Description

  The present invention relates to a connector.

There is known a connector that can be connected to an object to be connected so as to absorb a positional deviation from the object to be connected (see, for example, Patent Document 1).
The connector described in Patent Document 1 includes a fixed housing (fixing block) that is fixed to a substrate, and a movable housing (movable housing) that is separate from the fixed housing. The first fixed portion of the terminal (contact) is fixed to the movable housing, the second fixed portion of the terminal is fixed to the fixed housing, and the movable housing is held so as to float from the bottom surface side of the fixed housing. Then, the elastic portion between the first fixed portion and the second fixed portion in the terminal is elastically deformed, so that the movable housing can be moved with respect to the fixed housing. It can be absorbed.

  However, in the above-described connector, when the connection object is displaced in both directions parallel to the substrate, all the displacement is absorbed by elastic deformation of the elastic portion. Therefore, stress concentrates on the elastic part, and the contact may be broken.

  The present invention has been made to address the above problems. That is, an object of the present invention is to provide a connector that can absorb a positional deviation with respect to a connection object and that does not easily break a terminal.

  The connector according to the first aspect moves in a first direction and a second direction, which are directions perpendicular to each other in a direction along a plane of the board with respect to the fixed housing and the fixed housing. A movable housing, a fixed terminal held by the fixed housing, and a movable terminal formed separately from the fixed terminal and held by the movable housing and electrically connected to a connection object. The smooth surface of the fixed terminal and the smooth surface of the movable terminal are in contact with each other, so that the fixed terminal and the movable terminal are conductively connected, and the movable housing is connected to the fixed housing. When moving in the first direction, the fixed terminal and the movable terminal slide while keeping their smooth surfaces in contact with each other.

  In the first aspect, the connector includes a fixed terminal and a movable terminal formed separately from the fixed terminal. The fixed terminal is held by a fixed housing fixed to the substrate, and the movable terminal is held by a movable housing that can move in a direction along the plane of the substrate with respect to the fixed housing. And since the fixed terminal and the movable terminal are in contact, the fixed terminal and the movable terminal are conductively connected.

Furthermore, when the movable housing moves in the first direction, which is one of the directions along the plane of the substrate, with respect to the fixed housing, the fixed terminal and the movable terminal slide while keeping their smooth surfaces in contact with each other. To do. Thereby, the conduction connection between the fixed terminal and the movable terminal is maintained.
Thus, according to the connector which concerns on a 1st aspect, the position shift of a 1st direction can be absorbed by sliding with a fixed terminal and a movable terminal among the directions along the plane of a board | substrate. Therefore, compared to a connector that absorbs all of the positional deviations in both the first direction and the second direction (the direction perpendicular to the first direction out of the directions along the plane of the board), the stress generated in the terminal Concentration is suppressed, and as a result, breakage of the terminal is suppressed.
In addition, since the fixed terminal and the movable terminal are in contact with each other on the smooth surface, when both are in contact with each other on the plate thickness surface (punching surface), one is on the plate thickness surface and the other is in contact with the smooth surface. Compared to the case where the fixed terminal and the movable terminal are worn, wear due to sliding between the fixed terminal and the movable terminal is less likely to occur, and the conductive connection between the fixed terminal and the movable terminal is stabilized.

  In the connector according to the second aspect, even when the movable housing moves in the second direction with respect to the fixed housing, the fixed terminal and the movable terminal slide while keeping their smooth surfaces in contact with each other. To do.

  In the connector according to the second aspect, even when the movable housing moves in the second direction with respect to the fixed housing, the fixed terminal and the movable terminal slide while keeping their smooth surfaces in contact with each other. Misalignment not only in the direction but also in the second direction can be absorbed by sliding between the fixed terminal and the movable terminal. Therefore, the breakage of the terminal is further suppressed.

  The connector according to a third aspect is the first or second aspect, wherein the movable housing is a portion of the fixed terminal that contacts the movable terminal with respect to the movable housing of the fixed side sliding portion. When the fixed side sliding portion is constrained by the constraining range, the fixed terminal and the movable terminal are conductively connected.

  In the connector according to the third aspect, the movable housing has a restraining portion. The restraining part has a function of restraining the position of the fixed side sliding part in the second direction with respect to the movable housing within a predetermined restraining range. When the fixed-side sliding portion is constrained within a predetermined constraining range, the fixed terminal and the movable terminal are electrically connected. For this reason, even if the displacement in the second direction cannot be absorbed by sliding, or even if the displacement in the second direction can be absorbed by sliding, the restraining part can slide the fixed side. By moving the position of the portion relative to the fixed housing in the second direction, it is possible to greatly absorb the positional deviation in the second direction.

  Here, the “restraint range” includes a range having substantially no width.

  In the connector according to a fourth aspect, in the first or second aspect, the fixed housing is a portion of the movable terminal that contacts the fixed terminal. When the movable side sliding portion is restrained by the restraining range, the fixed terminal and the movable terminal are conductively connected.

  In the connector according to the fourth aspect, the fixed housing has a restraining portion. The restraining portion has a function of restraining the position of the movable side sliding portion in the second direction with respect to the fixed housing within a predetermined restraining range. When the movable side sliding portion is constrained within a predetermined constraining range, the fixed terminal and the movable terminal are electrically connected. For this reason, even if the displacement in the second direction cannot be absorbed by sliding, or even if the displacement in the second direction can be absorbed by sliding, the restraint part can move the movable side. By moving the position of the part with respect to the movable housing in the second direction, it is possible to greatly absorb the positional deviation in the second direction.

  Here, the “restraint range” includes a range having substantially no width.

  In the connector according to the fifth aspect, in the third or fourth aspect, the constraining range is a range having a width in the second direction.

  In the connector according to the fifth aspect, the restraint range is a range having a width in the second direction. For this reason, when the positional deviation in the second direction is small, the positional deviation can be absorbed by sliding. Further, when the positional deviation in the second direction increases, the positional deviation can be absorbed by deformation.

  The connector according to a sixth aspect is the contact according to any one of the first to fifth aspects, wherein the fixed side sliding part is a part that contacts the movable terminal in the fixed terminal, and the fixed terminal in the movable terminal. The width of the plate along the second direction is different from that of the movable sliding portion which is a portion to be performed.

  In the connector according to the sixth aspect, the fixed side sliding portion and the movable side sliding portion have different plate widths along the second direction. For this reason, when the fixed-side sliding portion and the movable-side sliding portion slide in the second direction, the contact state is maintained without reducing the mutual contact width in the sliding range in which the mutual plate widths are different. be able to.

  A connector according to a seventh aspect is the spring piece portion according to the third aspect, which is a portion located between the fixed portion that is fixed to the fixed housing in the fixed terminal and the fixed-side sliding portion. Is configured to include a curved portion that extends along the first direction when viewed from a direction orthogonal to the plane of the substrate and is bent in a direction substantially orthogonal to the plane of the substrate.

  In the seventh aspect, the portion (fixed portion) fixed to the fixed housing in the fixed terminal and the portion (spring piece portion) positioned between the fixed-side sliding portion are viewed from the direction orthogonal to the plane of the substrate. And a curved portion that is bent in a direction substantially perpendicular to the plane of the substrate. The spring piece portion is a portion that is deformed when the stationary side sliding portion is moved in the second direction with respect to the stationary housing by the restraining portion. Since this spring piece portion extends along the first direction when viewed from the direction orthogonal to the plane of the substrate, and includes a bent portion bent in a direction substantially orthogonal to the plane of the substrate. The stress is suppressed from concentrating on a part of the spring piece part, and the breakage of the terminal is further suppressed.

  As described above, the present invention has an excellent effect that it can absorb the positional deviation from the connection object and the terminal is not easily broken.

The holding portion 24 has a groove shape that penetrates the front wall 22F in the vertical direction and is open even when directed forward. A fixing portion 42 of the fixing terminal 40 is press-fitted and fixed to the holding portion 24.

<Fixed terminal 40>
The three fixed terminals 40 have the same configuration. In the drawings, reference numerals for the fixed terminals 40 other than the center are omitted as appropriate.

  The fixed terminal 40 is formed by punching a metal plate material and then bending it. Therefore, the front surface and the back surface (surfaces on both sides in the plate thickness direction) of the fixed terminal 40 are smoother than the surfaces formed by punching (surfaces connecting the front surface and the back surface, punched surfaces). ing. In the present specification, the front and back surfaces of the fixed terminal 40 are referred to as “smooth surfaces”. In addition, let the surface which faced the connector upper side among the smooth surfaces of the fixed terminal 40 be a surface, and let the surface which faced the connector lower side be a back surface.

  As shown in FIGS. 2 and 4, the fixed terminal 40 has a board connecting part 41, a fixing part 42, a first curved part 43, a first straight part 44, a second curved part 45, from one end to the other end. It has the 2nd linear part 46 and the fixed side sliding part 47 in this order.

  The board connecting part 41 is a part connected to a land pattern of the board 90 by soldering. The board connecting portion 41 has the plate thickness direction directed in the vertical direction, and extends backward from one end to the other end. The other end side of the board connection part 41 in the extending direction is connected to the fixing part 42 through a bent part.

  The fixing portion 42 is a portion that is press-fitted and fixed to the holding portion 24 of the fixed housing 20. The fixing portion 42 has the plate thickness direction in the front-rear direction, and extends upward from one end to the other end. Locking protrusions (not shown in the figure) are formed on both sides of the fixing portion 23 in the plate width direction (both sides in the connector width direction). The fixing portion 42 is fixed to the holding portion 24 by the locking projections biting into the fixed housing 20. Thereby, the fixed terminal 40 is held by the fixed housing 20. The other end side in the extending direction of the fixing portion 23 is connected to the first curved portion 43.

  The first curved portion 43 is bent toward the back side in the plate thickness direction, and has a curved shape that is convex upward. The first curved portion 43 changes the direction of extension from one end to the other end by approximately 180 degrees. The other end side in the extending direction of the first curved portion 43 is connected to the first straight portion 44.

  The first straight portion 44 has the plate thickness direction in the front-rear direction, and extends downward from one end to the other end. The other end side in the extending direction of the first straight portion 44 is connected to the second curved portion 45.

  The second curved portion 45 is bent toward the surface side in the thickness direction, and has a curved shape that protrudes downward. The second curved portion 45 has its extending direction changed by approximately 120 degrees from one end to the other end, and the other end is inclined slightly upward with respect to the rear direction (backward and upward oblique direction). It extends. The position of the second curved portion 45 in the height direction is a position lower than the center in the height direction of the front wall 22F of the fixed housing 20 (that is, the position near the bottom wall 21). The position in the front-rear direction is a position in front of the center in the front-rear direction of the bottom wall 21 of the fixed housing 20 (that is, a position near the front wall 22F). The other end side in the extending direction of the second curved portion 45 is connected to the second linear portion 46.

  The second straight portion 46 has a plate thickness direction substantially in the vertical direction, and is linear in a direction slightly inclined upward (backward and upward oblique direction) from one end to the other end with respect to the rear direction. It extends to. The other end side in the extending direction of the second straight portion 46 is connected to the fixed-side sliding portion 47 through a bent portion slightly bent toward the surface side in the plate thickness direction.

  The fixed-side sliding portion 47 is bent toward the back side in the thickness direction, and has a curved shape that is convex upward. Thereby, the surface which is the upper surface of the fixed-side sliding portion 47 is curved upward and convex. A convex curved portion of the surface of the fixed side sliding portion 47 is in contact with the movable side sliding portion 51 of the movable terminal 50. In the state shown in FIGS. 1 to 4 (hereinafter, this state may be referred to as “normal state”), the fixed terminal 40 is elastically deformed, and the fixed side sliding portion 47 and the movable side slide are in the state. An upward load (elastic force) acts on the moving part 51. That is, the fixed terminal 40 is fixed to the holding portion 24 of the fixed housing 20 at the fixed portion 42, and receives a downward load from the movable terminal 50 and the movable housing 30 at the fixed-side sliding portion 47. As a result, a portion of the fixed terminal 40 between the fixed portion 42 and the fixed-side sliding portion 47 (hereinafter, referred to as “spring piece portion”. First curved portion 43, first straight portion 44, second curved portion) 45, the second straight portion 46, etc.) are elastically deformed. The movable terminal 50 and the movable housing 30 are pushed upward by the elastic force of the three fixed terminals 40, and the left and right protrusions 31 of the movable housing 30 are pressed against the upper wall 73 of the fixed metal fitting 70.

<Movable housing 30>
The movable housing 30 includes a substantially cylindrical upper portion 30U, a substantially rectangular parallelepiped intermediate portion 30I, and a substantially rectangular parallelepiped lower portion 30L having protrusions 31 projecting to both sides in the width direction from the intermediate portion. . The movable housing 30 is formed of an insulator such as synthetic resin, and is separate from the fixed housing 20.

As described above, the left and right protrusions 31 of the movable housing 30 are disposed in the left and right spaces 25 (see FIG. 13) formed by the fixed housing 20 and the fixing bracket 70. The left and right protrusions 31 of the movable housing 30 are constrained in the left and right spaces 25, thereby restricting the movable range of the movable housing 30 in the front and rear and upper and lower directions.
An intermediate portion 30I of the fixed housing 20 is disposed between the upper walls 73 of the left and right fixing brackets 70. Since the intermediate portion 30I of the fixed housing 20 contacts the upper walls 73 of the left and right fixing brackets 70, the left and right movable ranges of the movable housing 30 are limited.

  The movable housing 30 has a housing portion 32 for housing the movable terminal 50. The accommodating portions 32 are formed by the number of movable terminals 50 (three in this embodiment). The accommodating part 32 includes a holding part 33 for holding the movable terminal 50. Since the fixed portion 52 of the movable terminal 50 is fixed to the holding portion 33 of the movable housing 30, the movable terminal 50 is held by the movable housing 30.

  Of the three accommodating portions 32, the central accommodating portion 32 and the left and right accommodating portions 32 are configured differently.

  The central accommodating portion 32 (hereinafter, also referred to as “central accommodating portion 32”) is a through-hole penetrating the movable housing 30 up and down. The central housing portion 32 passes through the upper portion 30U, the intermediate portion 30I, and the lower portion 30L of the movable housing 30. The upper end of the central housing portion 32 opens upward in an opening portion 32 </ b> A formed on the upper surface of the upper portion 30 </ b> U of the movable housing 30. The opening 32A is an opening for inserting a counterpart terminal 80 (see FIG. 4) as a “connection object”. The opening 32A is formed with a tapered surface 32AT for guiding the mating terminal 80 from the front, rear, left and right into the central housing portion 32.

  The portion of the central housing portion 32 that accommodates the counterpart terminal 80 is located at the center of the cylindrical upper portion 30U of the movable housing 30, and is a long hole space that extends in the vertical direction and has a rectangular shape in plan view. is there.

  The center housing portion 32 is enlarged forward with respect to the above-described space (a long hole space extending in the vertical direction which is rectangular in plan view) in which the counterpart terminal 80 is housed. The central movable terminal 50 is disposed in this expanded space. The space expanded in the front where the central movable terminal 50 is arranged has a smaller dimension in the connector width direction than the space in which the counterpart terminal 80 is accommodated.

  On the other hand, as shown in FIG. 3, the left and right outer storage portions 32 (outer storage portions 32) have a groove shape that is open toward the front.

<Movable terminal 50>
Of the three movable terminals 50, the central movable terminal 50 is a signal terminal, and the two movable terminals 50 on both sides are ground terminals (GND terminals).

  The movable terminal 50 is formed by bending after a metal plate material is punched. Therefore, the front surface and the back surface (surfaces on both sides in the plate thickness direction) of the movable terminal 50 are smoother than the surfaces formed by punching (surfaces connecting the front surface and the back surface, punched surfaces). ing. In the present specification, the front and back surfaces of the movable terminal 50 are referred to as “smooth surfaces”. In addition, let the surface of the side which contacts the other party terminal 80 among the smooth surfaces of the movable terminal 50 be a surface, and let the surface on the opposite side be a back surface.

  The central movable terminal 50 (hereinafter referred to as “central movable terminal 50”) and the movable terminals 50 on both sides (hereinafter referred to as “outer movable terminals”) are both movable side slides from one end to the other end. It has the moving part 51, the fixing | fixed part 52, and the other party connection part 53 in this order. The central movable terminal 50 and the outer movable terminal 50 have the same configuration in the movable side sliding portion 51 and the fixed portion 23, and have different configurations (shapes) in the mating side connection portion 53 (FIG. 2, FIG. 2). 3).

  The movable side sliding part 51 is a part that contacts the fixed side sliding part 47 of the fixed terminal 40. The movable-side sliding portion 51 has the plate thickness direction directed in the vertical direction, and linearly extends forward from one end to the other end. The back surface (lower surface) of the movable sliding portion 51 is in contact with the surface (upper surface) of the fixed sliding portion 47. The other end side of the movable-side sliding portion 51 is connected to the fixed portion 52 via a bent portion that is bent approximately 90 degrees toward the surface side in the plate thickness direction.

  The fixed portion 52 is a portion that is press-fitted and fixed to the holding portion 33 of the movable housing 30. The fixing portion 52 has the plate thickness direction in the front-rear direction, and extends linearly upward from one end to the other end. Locking projections (not shown in the figure) are formed on both sides of the fixing portion 52 in the plate width direction (both sides in the connector width direction). The fixing portion 52 is fixed to the holding portion 33 of the movable housing 30 by the engagement protrusions biting into the movable housing 30. Thereby, the movable terminal 50 is held by the movable housing 30. The fixed portion 52 is disposed on the front side of the center of the movable housing 30 in the front-rear direction. The other end side in the extending direction of the fixing portion 52 is connected to the mating connection portion 53 via a bent portion bent approximately 20 degrees toward the surface side in the plate thickness direction.

  The counterpart connection part 53 of the central movable terminal 50 is a part that contacts and connects to the counterpart terminal 80 as a “connection object”. The mating connection part 53 has a straight part 53A, a curved part 53B, and a tip part 53C in this order from one end to the other end.

  The straight portion 53A has a plate thickness direction substantially in the front-rear direction, and extends linearly in a direction slightly inclined backward (upward and backward) from one end to the other end with respect to the upward direction. Yes. Thereby, the linear portion 53A gradually moves away from the front wall surface 32F of the central housing portion 32 as it goes from one end to the other end, and approaches the center of the movable housing 30 in the front-rear direction. The other end side of the linear portion 53A is connected to the curved portion 53B.

  The curved portion 53B is bent toward the back side in the thickness direction, and has a curved shape that is convex toward the rear. As a result, the curved portion 53B changes the direction of extension from one end to the other end from the upward and backward oblique direction to the upward and forward oblique direction. The other end side of the curved portion 53B is connected to the distal end portion 53C.

  The distal end portion 53C extends linearly in an oblique direction upward and forward from one end to the other end. A front wall surface 32F of the central housing portion 32 faces the front side of the distal end portion 53C. A step portion 32D is formed on the front wall surface 32F of the central housing portion 32, and the front wall surface 32F of the central housing portion 32 is enlarged forward in the upper portion thereof. Thereby, the space ahead of the front-end | tip part 53C of the other party connection part 53 of the movable terminal 50 (namely, space in which the movable terminal 50 can deform | transform) is widened.

When the mating terminal 80 is inserted into the central housing portion 32, the mating terminal 80 comes into contact with the distal end portion 53 </ b> C or the curved portion 53 </ b> B of the mating connection portion 53 of the movable terminal 50, and the distal end portion 53 </ b> C is in front of the central housing portion 32. The movable terminal 50 is elastically deformed so as to approach the wall surface 32F.
In addition, the other party connection part 53 of the outer side movable terminal 50 is set as the structure (shape) reverse to the center movable terminal 50 as shown in FIG. Thus, the counterpart connection portion 53 of the outer movable terminal 50 protrudes from the outer housing portion 32 formed in a groove shape in the movable housing 30 to the front side of the movable housing 30.

  As shown in FIGS. 6, 8, and 12, the movable housing 30 has an arrangement groove 34 in which the movable side sliding portion 51 of the movable terminal 50 is arranged. The arrangement groove 34 is formed on the lower surface of the lower portion 30 </ b> L of the movable housing 30. The arrangement groove 34 is a groove extending in the front-rear direction, and three arrangement grooves 34 are formed side by side in the connector width direction. The structures of the three arrangement grooves 34 are substantially the same. In the figure, reference numerals regarding the arrangement grooves 34 other than the center are omitted as appropriate.

  The length L (front-rear dimension) of the arrangement groove 34 is substantially the same as the front-rear dimension of the movable sliding portion 51. Thereby, the whole extending direction of the movable side sliding portion 51 is arranged in the arrangement groove 34.

  A depth D (vertical dimension) of the arrangement groove 34 is set to be larger than a plate thickness d (see FIGS. 6 and 7) along the vertical direction of the movable sliding portion 51. Therefore, the pair of side wall surfaces 34 </ b> S of the arrangement groove 34 protrudes downward from the movable side sliding part 51 in a state where the movable side sliding part 51 is arranged on the bottom 34 </ b> B of the arrangement groove 34.

  As shown in FIG. 6 and the like, a portion of the fixed-side sliding portion 47 that is in contact with the movable-side sliding portion 51 is disposed between the pair of side wall surfaces 34 </ b> S of the arrangement groove 34. The groove width W of the arrangement groove 34 (left and right dimensions, distance between the pair of side wall surfaces 34S) is substantially the same as the plate width of the movable side sliding portion 51, and the movable side sliding portion 51 is movable housing. 30 is not moved. On the other hand, the plate width of the fixed side sliding portion 47 is formed smaller than the plate width of the movable side sliding portion 51 and the groove width W of the arrangement groove 34. Thereby, the fixed side sliding part 47 can move in the width direction between the pair of side wall surfaces 34S.

  As shown in FIGS. 6 and 8, in the normal state, the fixed-side sliding portions 47 of the three fixed terminals 40 are all positioned at the center in the width direction of the three arrangement grooves 34.

  Next, the operation of the connector 10 will be described.

(Absorption of misalignment between front and back)
When the movable housing 30 moves forward from the normal state shown in FIG. 4, the state shown in FIG. That is, in the normal state shown in FIG. 4, the fixed-side sliding portion 47 is in contact with the vicinity of the center in the extending direction (front-rear direction) of the movable-side sliding portion 51. On the other hand, in the state shown in FIG. 5A, the fixed-side sliding portion 47 is in contact with one end side (the rear side in the front-rear direction) of the movable-side sliding portion 51. That is, as the movable housing 30 moves forward, the position of the movable side sliding portion 51 where the fixed side sliding portion 47 is in contact is rearward on the movable side sliding portion 51 extending in the front-rear direction. Move to.

  On the other hand, when the movable housing 30 moves rearward from the normal state shown in FIG. 4, the state shown in FIG. That is, in the normal state shown in FIG. 4, the fixed-side sliding portion 47 is in contact with the vicinity of the center in the extending direction (front-rear direction) of the movable-side sliding portion 51. On the other hand, in the state shown in FIG. 5B, the fixed side sliding portion 47 is in contact with the other end side (front side in the front-rear direction) of the movable side sliding portion 51. That is, as the movable housing 30 moves rearward, the position where the fixed-side sliding portion 47 is in contact with the movable-side sliding portion 51 moves forward on the movable-side sliding portion 51 extending in the front-rear direction. Move to.

  When the movable housing 30 moves forward or backward, the fixed-side sliding portion 47 and the movable-side sliding portion 51 slide while keeping their smooth surfaces in contact with each other. Thereby, while the movable housing 30 is moving, the conduction connection between the fixed terminal 40 and the movable terminal 50 is maintained, and the conduction connection is stably maintained after the movement.

(Left and right misalignment absorption)
When the movable housing 30 moves to the left from the normal state shown in FIGS. 6 and 8, the state shown in FIGS. 7 and 9 is obtained. That is, in the normal state shown in FIGS. 6 and 8, the fixed-side sliding portion 47 is spaced from both the pair of side wall surfaces 34 </ b> S of the arrangement groove 34. On the other hand, in the state shown in FIGS. 7 and 9, the right side wall surface 34S of the arrangement groove 34 abuts on the fixed side sliding portion 47 from the right side, and the fixed side sliding portion 47 is on the left side of the position in the normal state. It is moved to the position. In this state, the portion (spring piece portion 40D) between the fixed portion 23 of the fixed terminal 40 and the fixed-side sliding portion 47 is elastically deformed.

  The transition from the normal state to the state of FIG. 7 or FIG. 9 will be described in chronological order. First, the fixed side sliding portion 47 and the movable side sliding portion 51 are slid in the left-right direction while being in contact with each other. The right side wall surface 34S comes into contact with the fixed side sliding portion 47 from the right side, and the fixed terminal 40 is elastically deformed.

  In addition, although illustration is abbreviate | omitted, if the movable housing 30 moves to the right side from a normal state, it will carry out a symmetrical operation with the above-mentioned.

  As described above, the position of the fixed side sliding portion 47 in the left-right direction of the connector with respect to the movable housing 30 is constrained in the arrangement groove 34 (between the pair of side wall surfaces 34S) by the pair of side wall surfaces 34S of the arrangement groove 34. ing. And since the movable side sliding part 51 is arrange | positioned in the arrangement | positioning groove | channel 34, when the fixed side sliding part 47 is restrained in the arrangement | positioning groove | channel 34 (between a pair of side wall surfaces 34S), it is fixed side sliding. The part 47 and the movable side sliding part 51 are in contact with each other. That is, the pair of side wall surfaces 34S of the arrangement groove 34 restrains the position of the fixed side sliding portion 47 in the connector width direction with respect to the movable housing 30 in the arrangement groove 34, so that the movable housing 30 moves in the connector width direction. Sometimes, it can be regarded as a restraining portion 34S that keeps the conductive connection between the fixed terminal 40 and the movable terminal 50 (hereinafter, the same reference numeral 34S is used for the pair of side wall surfaces of the placement groove 34 and the restraining portion).

  The movable housing 30 may move not only in the front-rear direction and the left-right direction, but also in a combined movement. However, even in that case, the above-described operations are combined, so that a combined positional shift in the front, rear, left, and right can be absorbed. In addition, the movable housing 30 is slightly rotatable around the vertical axis. In this case as well, the movable housing 30 moves while the conductive connection between the fixed terminal 40 and the movable terminal 50 is maintained.

<Effect>
Next, the function and effect of the connector 10 according to this embodiment will be described.

  The connector 10 according to the present embodiment includes a fixed terminal 40 and a movable terminal 50 formed separately from the fixed terminal 40. The fixed terminal 40 is held by the fixed housing 20 that is fixed to the substrate 90, and the movable terminal 50 is held by the movable housing 30 that can move relative to the fixed housing 20. The fixed terminal 40 and the movable terminal 50 are in contact with each other, so that the fixed terminal 40 and the movable terminal 50 are conductively connected.

Furthermore, when the movable housing 30 moves in a first direction (connector longitudinal direction) which is one of the directions along the plane of the substrate 90 with respect to the fixed housing 20, the fixed terminal 40 and the movable terminal 50 are mutually connected. Slide while keeping smooth surfaces in contact. Thereby, the conductive connection between the fixed terminal 40 and the movable terminal 50 is maintained.
As described above, according to the connector 10 according to the present embodiment, at least the displacement in the first direction (the connector longitudinal direction) among the directions along the plane of the substrate 90 is caused by sliding between the fixed terminal 40 and the movable terminal 50. Can be absorbed. Therefore, a connector that absorbs all of the positional deviations in both the first direction (connector front-back direction) and the second direction (direction perpendicular to the first direction out of the directions along the plane of the board, connector left-right direction) by deformation of the terminals. As a result, the stress generated in a part of the terminal is suppressed, and as a result, the breakage of the terminal is suppressed.
In addition, since the fixed terminal 40 and the movable terminal 50 are in contact with each other on the smooth surface, when both are in contact with each other on the plate thickness surface (punching surface), one is on the plate thickness surface and the other is in contact with the smooth surface. Compared to the case where the fixed terminal 40 and the movable terminal 50 are worn, wear due to sliding between the fixed terminal 40 and the movable terminal 50 is less likely to occur, and the conductive connection between the fixed terminal 40 and the movable terminal 50 is stabilized.

  Further, in the connector 10 according to the present embodiment, even when the movable housing 30 moves in the second direction (connector left-right direction) with respect to the fixed housing 20, the fixed terminal 40 and the movable terminal 50 have the smooth surfaces of each other. Since the sliding is performed while being in contact, not only the first direction (connector longitudinal direction) but also the displacement in the second direction (connector lateral direction) can be absorbed by the sliding of the fixed terminal 40 and the movable terminal 50. it can. Therefore, the breakage of the terminal is further suppressed.

  Further, in the connector 10 according to the present embodiment, the movable housing 30 has a restraining portion 34S, and the restraining portion 34S is a position of the fixed-side sliding portion 47 in the second direction (connector left-right direction) with respect to the movable housing 30. Is constrained to a predetermined restraining range. When the fixed side sliding portion 47 is constrained within a predetermined restraining range, the fixed side sliding portion 47 and the movable side sliding portion 51 come into contact with each other, and the fixed terminal 40 and the movable terminal 50 are electrically connected. It is like that. For this reason, the dimension which follows the 2nd direction (connector left-right direction) of the fixed side sliding part 47 or the movable side sliding part 51 cannot be set large, but the sliding range which absorbs the position shift of a 2nd direction (connector left-right direction). Even when the fixed terminal 40 is narrow (for example, when a plurality of the fixed terminals 40 and the movable terminals 50 are arranged in parallel in the connector width direction as in the present embodiment), the fixed side sliding portion 47 is fixed to the fixed housing 20 by the restricting portion 34S. By moving the position in the second direction (connector left-right direction), it is possible to greatly absorb the position shift in the second direction (connector left-right direction).

  In the connector 10 according to the present embodiment, the predetermined restraining range restrained by the restraining portion 34S is a range having a width in the second direction (connector left-right direction). For this reason, when the positional deviation in the second direction (connector left-right direction) is small, the positional deviation can be absorbed by the sliding of the fixed terminal 40 and the movable terminal 50. When the positional deviation in the second direction (connector left-right direction) becomes large, the positional deviation can be absorbed by the deformation of the fixed terminal 40.

  In the connector 10 according to the present embodiment, the fixed side sliding portion 47 and the movable side sliding portion 51 have different plate widths along the second direction (connector width direction). For this reason, when the fixed-side sliding portion 47 and the movable-side sliding portion 51 slide in the second direction (connector width direction), the mutual contact width is set within the sliding range in which the mutual plate widths are different. The contact state can be maintained without reduction.

  Further, in the connector 10 according to the present embodiment, the spring piece portion 40D (the first curved portion 43, the first straight portion 44, the second curved portion 45, the first curved portion 45, the second curved portion 45, which is located between the fixed portion 42 and the fixed-side sliding portion 47. The bilinear portion 46) extends along the first direction (connector front-rear direction) when viewed from the direction orthogonal to the plane of the substrate 90, and in the direction orthogonal to the plane of the substrate 90 (connector up-down direction). It is comprised including the bent music part (the 1st music part 43, the 2nd music part 45). The spring piece portion 40D is a portion that is deformed when the restraint portion 34S moves in the second direction (connector left-right direction) with respect to the fixed housing 20 of the fixed-side sliding portion 47 (see FIGS. 7 and 9). The spring piece portion 40D extends along the first direction (the connector longitudinal direction) when viewed from the direction orthogonal to the plane of the substrate 90, and is bent in the direction orthogonal to the plane of the substrate 90 (connector vertical direction). Since the curved portions (the first curved portion 43 and the second curved portion 45) are included, the concentration of stress on a part of the spring piece portion 40D is suppressed, and the breakage of the terminal is further suppressed. Is done.

  Further, in the connector 10 according to the present embodiment, since the spring piece portion 40D has two curved portions (the first curved portion 43 and the second curved portion 45), stress concentration is less likely to occur.

  In the connector 10 according to the present embodiment, the second linear portion 46 between the curved portions (the first curved portion 43 and the second curved portion 45) included in the spring piece portion 40D and the fixed-side sliding portion 47 is provided. The direction along the first direction (the longitudinal direction of the connector) extends as the longitudinal direction. The second curved portion 45 is located near the front wall 22 </ b> F of the fixed housing 20. For this reason, the fixed-side sliding portion 47 is greatly moved by a small deformation of the curved portion.

  Further, in the connector 10 according to the present embodiment, the restraining portion 34 </ b> S is configured by a pair of side wall surfaces 34 </ b> S of the arrangement groove 34. Therefore, not only when the movable housing 30 moves to one side (connector left side) in the second direction with respect to the fixed housing 20, but also when the movable housing 30 moves to the other side (connector right side), the fixed side sliding portion The side wall surface 34 </ b> S abuts on 47 and the fixed terminal 40 can be deformed.

  Further, in the connector 10 according to the present embodiment, the fixed side sliding portion 47 is pressed against the movable side sliding portion 51 by the elastic force of the fixed terminal 40. The contact state between the fixed-side sliding portion 47 and the movable-side sliding portion 51 is kept good.

  Furthermore, in the connector 10 according to the present embodiment, the movable housing 30 is movable in a predetermined movable range in a direction perpendicular to the plane of the substrate 90 (connector up-down direction) with respect to the fixed housing 20 fixed to the substrate 90. The conductive connection between the fixed terminal 40 and the movable terminal 50 is maintained in the entire upper and lower movable range. For this reason, the positional deviation in the direction perpendicular to the substrate 90 can also be absorbed.

[Supplementary explanation of the above embodiment]
In the above-described embodiment, the example in which the fixed terminal 40 is held in the fixed housing 20 by press-fitting and the movable terminal 50 is held in the movable housing 30 by press-fitting has been described, but the present invention is not limited to this, and the fixed terminal The movable terminal may be held by other methods.

  Moreover, although the said embodiment demonstrated the example by which the part different from the fixing | fixed part 52 was made into the movable side sliding part 51 among the movable terminals 50, this invention is not limited to this. For example, the movable terminal 50 may be fixed to the movable housing 30 in the movable side sliding portion 51. That is, the movable side sliding part and the movable side fixed part may be the same part.

  Further, in the above embodiment, the depth D of the arrangement groove 34 is larger than the plate thickness of the movable side sliding portion 51, and is larger than the movable side sliding portion 51 of the pair of side wall surfaces 34 </ b> S of the arrangement groove 34. The example in which the portion protruding downward from the connector functions as the restraining portion 34S has been described. However, the depth D of the arrangement groove 34 may be formed smaller than the plate thickness of the movable side sliding portion 51. That is, the movable housing 30 may not have the restraining portion 34S.

  In the above-described embodiment, the example in which the movable housing 30 is movable in a predetermined movable range in the connector vertical direction has been described. However, the movable housing 30 may be configured not to move in the vertical direction of the connector. .

Moreover, in the said embodiment, you may reverse the structure of the part vicinity which the fixed terminal 40 and the movable terminal 50 contact. That is, by providing a “restraining portion” in the fixed housing 20 instead of the movable housing 30, the movable terminal 50 may be deformed when the movable housing 30 moves in the second direction.
That is, in this case, the “restraint portion” of the fixed housing 20 has a function of restraining the position of the movable side sliding portion in the second direction with respect to the fixed housing within a predetermined restraint range. When the movable side sliding portion is constrained within a predetermined constraining range, the conductive connection between the fixed terminal and the movable terminal is maintained. For this reason, even when the dimension along the second direction of the fixed side sliding part or the movable side sliding part cannot be set large, the position of the movable side sliding part with respect to the movable housing is moved in the second direction. The displacement in the two directions can be greatly absorbed.
