Description

  The present invention relates to a connector device including one or a plurality of mating connectors and a joint connector that electrically connects a plurality of electric wires belonging to the mating connectors.

  Conventionally, a joint connector having a bus bar has been proposed for the purpose of connecting a plurality of electric wires extending from a plurality of electric / electronic devices provided in an automobile or the like.

  For example, one of the conventional joint connectors (hereinafter referred to as “conventional connector”) includes a bus bar having a plurality of pin terminals for fitting and connecting to terminals provided at terminals of a plurality of electric wires belonging to the mating connector; And a housing for accommodating the bus bar. The housing is provided with a plurality of fitting chambers corresponding to a plurality of mating connectors (see, for example, Patent Document 1).

JP 2010-123296 A JP 2000-067980 A JP 2002-231364 A

  By the way, the connector may be provided with a spacer for fixing (locking) the terminal accommodated in the terminal accommodating chamber of the connector (see, for example, Patent Documents 2 and 3). The spacer is generally inserted into an insertion space formed inside the connector and locked to the connector. For example, when the spacer is inserted into the insertion space, the above-described locking is performed by engaging the locking piece of the spacer with the locked portion of the connector.

  When such a spacer is applied to a mating connector of a conventional connector, an insertion space is provided inside the mating connector, and a locked portion for locking the spacer is added to the mating connector. Therefore, if such application is inadvertently performed, the counterpart connector may be enlarged. When the mating connector increases in size, the joint connector fitting chamber is enlarged to match the mating connector, and as a result, the joint connector itself may increase in size. From the viewpoint of avoiding an increase in the size of the joint connector, it is desirable to apply a spacer to the mating connector while avoiding an increase in the size of the mating connector as much as possible.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a connector device in which a spacer locking structure provided on a mating connector of a joint connector is simplified as much as possible.

In order to achieve the above-described object, the connector device according to the present invention is characterized by the following (1) and (2).
(1)
A connector device comprising one or a plurality of mating connectors and a joint connector for electrically connecting a plurality of electric wires belonging to the mating connector,
The joint connector is
A housing having one or a plurality of fitting chambers into which the mating connector is fitted;
The housing is
A partition wall that divides each of the fitting chambers, and a plurality of ridges formed on the wall surface of the partition wall so as to extend along the fitting direction of the mating connector,
The mating connector is
A main body having a shape corresponding to each of the plurality of ridges and having a plurality of recesses on the outer wall surface extending along the fitting direction, and a terminal for accommodating a terminal provided at the end of the electric wire A storage chamber, and a spacer having a locking piece inserted into an insertion space formed inside the main body in a direction intersecting the fitting direction and locked to the main body,
The spacer is
The locking piece is formed at a peripheral portion of the first through hole that forms a part of the terminal accommodating chamber and opens to the bottom surface of one of the plurality of recesses so as to communicate with the insertion space. When in the temporarily locked state to be locked, the terminal is allowed to move in the axial direction of the terminal accommodating chamber, and is inserted into the insertion space on the bottom surface of the other one of the plurality of recesses. Prohibiting movement of the terminal in the axial direction when the locking piece is locked in the peripheral portion of the second through-hole that is open to communicate with the locking piece;
It must be a connector device.
(2)
In the connector device according to (1) above,
The spacer is
When in the temporarily locked state, at least a part is exposed to the outside of the main body part and hinders fitting of the mating connector to the fitting chamber,
When in the main locking state, the whole is stored inside the main body and does not hinder the mating connector from being fitted into the mating chamber.
It must be a connector device.

  According to the connector device having the configuration of (1) above, the inner side of the mating connector is formed on the bottom surface of the recess formed in the outer wall surface of the mating connector (the guide groove corresponding to the convex strip formed in the joint connector). A through hole communicating with the spacer insertion space is provided. And the latching piece of a spacer is latched using the peripheral part (for example, side wall surface of the groove | channel for a guide) of the through-hole. In other words, the concave portion (guide groove) is also used as a portion (locked portion) for locking the locking piece. Therefore, the spacer locking structure can be simplified as compared with the case where a portion (locked portion) for locking the locking piece of the spacer is separately provided on the mating connector. Furthermore, even if the spacer locking structure is simplified in this way, by using the through holes (first through hole and second through hole) formed in the bottom surfaces of the two recesses (guide grooves), the terminal by the spacer is used. The holding function can also be maintained. As a result, an increase in size of the mating connector (and consequently an increase in size of the joint connector) can be avoided.

  According to the connector device having the above configuration (2), when the spacer is in the temporary locking position, the mating connector cannot be fitted in the fitting chamber of the joint connector, and the spacer is in the final locking position. Only the mating connector can be fitted into the fitting chamber of the joint connector. Therefore, it is possible to prevent the mating connector from being fitted into the joint connector in a state where the spacer is in the temporary locking position and the function as the spacer (holding of the terminal) is not sufficiently exhibited.

  ADVANTAGE OF THE INVENTION According to this invention, the connector apparatus which simplified the latching structure of the spacer provided in the other party connector of a joint connector as much as possible can be provided.

  The present invention has been briefly described above. Further, details of the present invention will be further clarified by reading a form for carrying out the invention described below (hereinafter referred to as “embodiment”) with reference to the accompanying drawings.

<Embodiment>
Hereinafter, a connector device according to an embodiment of the present invention will be described with reference to the drawings.

  A connector device 100 according to an embodiment of the present invention includes a joint connector JC shown in FIGS. 1 to 3 and a mating connector 40 shown in FIGS. 4 to 7 (see FIGS. 8 and 9). As shown in FIG. 1, the joint connector JC includes a bus bar 10, a housing 20 that houses the bus bar 10, and a cover 30 that covers the bus bar 10 housed in the housing 20.

  Hereinafter, as shown in FIGS. 1, 2, 4, 7, 8, and 9, “the mating direction of the mating connector” (hereinafter simply referred to as “the mating direction”), “the width direction”. ”,“ Vertical direction ”,“ front ”,“ rear ”,“ upper ”and“ lower ”. The “fitting direction”, “width direction”, and “vertical direction” are orthogonal to each other.

  As shown in FIG. 1, the housing 20 accommodates the bus bar 10 from the front side in the fitting direction, and the mating connector 40 (see FIGS. 8 and 9) from the rear side. ing. Here, the joint connector JC allows a plurality of electric wires (not shown) belonging to the mating connector 40 to be connected to each other via the bus bar 10 with respect to the electric wire conduction pattern corresponding to the type of the mating connector 40 (number of electric wires, electric wires). The function of conducting a conductive connection so as to realize a combination, the position of the electric wire in the mating connector, etc.).

  As shown in FIG. 1, the metal bus bar 10 includes a plurality of terminal portions 11 and a connecting portion 12 that extends in the width direction and connects the front end portions of the plurality of terminal portions 11. The plurality of terminal portions 11 extend in parallel with each other toward the rear from the connecting portion 12 so as to be arranged at equal intervals in the width direction.

  In this example, a plurality (specifically, eight) bus bars 10 are used. Specifically, four of the seven fitting chambers 24 (see FIG. 1) to be described later are provided with three terminal portions 11 with respect to the three fitting chambers 24 adjacent in the left region when viewed from the rear side. The bus bar 10 is used in four stages in the vertical direction. In addition, four bus bars 10 including four terminal portions 11 are divided into four stages in the vertical direction with respect to four fitting chambers 24 adjacent to each other in the right region when viewed from the rear side among the seven fitting chambers 24. Used.

  As shown in FIG. 1, the resin housing 20 includes a rectangular tube-shaped main body peripheral wall portion 21 that is long in the width direction. A rectangular locking projection 22 that is long in the width direction for locking the cover 30 is integrally provided at the front end of the peripheral wall portion 21 so as to protrude forward.

  A plurality of busbars penetrating in the fitting direction corresponding to a plurality (specifically, eight) of the busbars 10 used in four stages as described above are accommodated inside the locking projection 22. A hole (not shown) is provided at a predetermined position. A corresponding bus bar 10 (terminal portion 11) is press-fitted and fixed to each bus bar accommodating hole to a predetermined position.

  In a state in which each bus bar 10 is fixed, the plurality of terminal portions 11 of the bus bar 10 are forward in the fitting direction in the internal space of the main body peripheral wall portion 21 (more specifically, in the fitting chamber 24 described later). It extends backward from. In this state, by mating the mating connector 40 into the mating chamber 24, each terminal portion 11 corresponds to the corresponding female terminal 44 accommodated in the terminal accommodating chamber 43 of the mating connector 40 (see FIG. 7). ) And are connected to each other.

  In this manner, the cover 30 is assembled to the locking protrusion 22 of the housing 20 in a state where each bus bar 10 is fixed. As shown in FIG. 1, the resin cover 30 includes a rectangular tube-shaped frame body portion 31 that is long in the width direction. A lid plate portion 32 is integrally provided at the front end portion of the frame body portion 31.

  The cover 30 is assembled to the housing 20 by fitting and locking the frame body portion 31 of the cover 30 to the locking protrusion 22 of the housing 20. As shown in FIG. 2, by assembling the cover 30 to the housing 20, the connecting portions 12 of the plurality of bus bars 10 are covered with the cover plate portions 32 of the cover 30, thereby preventing the bus bars 10 from falling off the housing 20. Can be done. In addition, intrusion of dust or the like from the front side of the housing 20 to the inside can be prevented. As described above, the assembly of the joint connector JC is completed by assembling the plurality of bus bars 10 and the cover 30 to the housing 20 (an assembly completion state).

  As shown in FIGS. 1 to 3, the internal space of the body peripheral wall portion 21 of the housing 20 is adjacent in the width direction by a plurality (specifically, six) partition walls 23 extending in the vertical direction and the fitting direction. Are divided into a plurality (specifically, seven) of fitting chambers 24.

  As shown in FIG. 3, a plurality of side inner wall surfaces (specifically, an inner wall surface of the body peripheral wall portion 21 and a wall surface of the partition wall 23) of each fitting chamber 24 extend along the fitting direction. (Specifically, three) ridges 25 are formed. The rear end of each ridge 25 is located on the front side of the rear end surface of the main peripheral wall 21 and on the rear side of the rear end of the terminal portion 11 of the bus bar 10 fixed to the housing 20. ing. In addition, about each fitting chamber 24, the protruding item | line part 25 should just be formed in one or more side inner wall surfaces, and two or more in the other side inner wall surface.

  When viewed from the rear side, the “form” of the protrusion 25 may be the same or different for each fitting chamber 24. Here, the “form” refers to the position and shape (size in the width direction and vertical direction, etc.) when viewed from the rear side. In the example shown in FIG. 1 to FIG. 3, the three fitting chambers 24 adjacent in the left region as viewed from the rear side and the four fitting chambers 24 adjacent in the right region as viewed from the rear side are convex. The “form” of the strip 25 is different.

  As shown in FIGS. 4 to 7, the resin main body (housing) 41 of the mating connector 40 has an outer shape corresponding to the fitting chamber 24. The interior of the main body 41 corresponds to the bus bar 10 used in four stages as described above, and a plurality (specifically, three) partition walls 42 are adjacent to each other in the vertical direction. In the example, it is divided into four terminal housing chambers 43 (see FIG. 7). Each terminal accommodating chamber 43 extends in the fitting direction, and a female terminal 44 connected to an end of an electric wire (not shown) is accommodated in each terminal accommodating chamber 43 from the rear side.

  A plurality of (three in this example) recesses 45 extending along the fitting direction are formed on the side outer wall surface of the mating connector 40. The “form” of the concave portion 45 of the mating connector 40 matches the “form” of the convex portion 25 in the fitting chamber 24 to be fitted. In other words, the “form” of the protrusion 25 formed in the fitting chamber 24 and the “form” of the recess 45 formed in the mating connector 40 are different for each type (conduction pattern) of the mating connector 40. Is different.

  As a result, even if an incorrect type of mating connector 40 is to be fitted into the mating chamber 24, the “form” of the recess 45 of the mating connector 40 matches the “form” of the ridge 25 of the mating chamber 24. Due to this, the mating connector 40 cannot be fitted into the fitting chamber 24. As a result, erroneous insertion of the mating connector 40 can be detected.

  As shown in FIG. 7, each of the bottom wall of the main body portion 41 extending along the fitting direction and the plurality of partition walls 42 extending along the fitting direction inside the main body portion 41 is the center in the fitting direction. Only a predetermined range in the vicinity is removed. As a result, an insertion space 47 (see FIGS. 4 to 6) is formed in the main body 41 so as to continuously extend in the vertical direction between the upper wall and the lower wall of the main body 41. . The insertion space 47 is closed at the upper end by the upper wall of the main body 41 and opened at the lower end (see FIG. 6).

  Through holes 46 (46 a, 46 b, 46 c) that are open to communicate with the insertion space 47 are formed in the fitting direction range corresponding to the insertion space 47 on the bottom surface of each recess 45 of the main body 41. (See FIGS. 4 and 6).

  A spacer 50 (see FIG. 4) is inserted into the insertion space 47 from below (in a direction crossing the fitting direction). The spacer 50 is a member for inhibiting the movement of the female terminal 44 accommodated in the terminal accommodating chamber 43 in the axial direction (that is, the fitting direction) (that is, preventing the female terminal 44 from coming off). Hereinafter, the spacer 50 will be described.

  As shown in FIG. 4, the resin spacer 50 includes a pair of side plates 51 extending in the vertical direction and facing in the width direction, and a plurality (four in this example) of connection plates 52 that connect the pair of side plates 51. And comprising. The space between the pair of side plates 51 is divided into a plurality of spaces 53 adjacent in the vertical direction by the plurality of connecting plates 52. The interval between the adjacent connecting plates 52 in the vertical direction is the same as the interval between the adjacent partition walls 42 of the main body 41 (see FIG. 7A). Locking pieces 54 that protrude outward in the width direction are provided on the outer surface of each side plate 51 on the rear end side in the fitting direction (see FIGS. 4 to 6).

  Hereinafter, for convenience of explanation, as shown in FIG. 6, the three concave portions 45 are distinguished from the concave portions 45 a, the concave portions 45 b and the concave portions 45 c, and the three through holes 46 are referred to as the through holes 46 a, the through holes 46 b and the through holes 46 c. The two locking pieces 54 may be referred to as the locking piece 54a and the locking piece 54b.

  When the spacer 50 is inserted into the insertion space 47 from the bottom to the top, the spacer 50 is first locked at the temporary locking positions shown in FIGS. 6 (a) and 7 (a). In the temporary locking position, the locking piece 54a is exposed to the through hole 46a of the recess 45a and engaged with the upper side wall of the recess 45a, and the locking piece 54b is exposed to the through hole 46c of the recess 45c and the recess. Engages with the lower side wall of 45c. The spacer 50 is locked at the temporary locking position by these two engagements.

  As shown in FIG. 7A, in the temporary locking position, the vertical positions of the plurality of connecting plates 52 coincide with the vertical positions of the plurality of partition walls 42 of the main body 41. In other words, each connecting plate 52 functions as a part of the corresponding partition wall 42, and each space 53 in the spacer 50 forms a part of the corresponding terminal accommodating chamber 43.

  Therefore, as shown in FIG. 7A, the female terminal 44 is inserted into the terminal accommodating chamber 43 with the spacer 50 in the temporary locking position. At this time, the female terminal 44 is inserted to a position where a locking portion (not shown) of the female terminal 44 is engaged with a lance 49 provided in the terminal accommodating chamber 43.

  As shown in FIGS. 6A and 7A, in the temporary locking position, the lower end portion 55 of the spacer 50 (the pair of side plates 51) is exposed to the outside of the main body portion 41 (the bottom wall of the main body portion 41). Protruding further downward). Therefore, even if the mating connector 40 is to be fitted into the fitting chamber 24 in a state where the spacer 50 is in the temporary locking position, it cannot be fitted until the fitting is completed. As a result, it is possible to prevent the mating connector 40 from being fitted into the fitting chamber 24 in a state where the female terminal 44 is not sufficiently held by the mating connector 40.

  After the female terminal 44 is inserted into the terminal accommodating chamber 43 in a state where the spacer 50 is in the temporary locking position, the spacer 50 is inserted further upward as shown in FIG. It is locked at the final locking position shown in FIG. At the main locking position, the locking piece 54a is exposed to the through hole 46b of the recess 45b and engaged with the lower side wall of the recess 45b, and the locking piece 54b is exposed to the through hole 46c of the recess 45c. Engages with the upper side wall of the recess 45c. By these two engagements, the spacer 50 is locked at the final locking position.

  As shown in FIG. 7B, in the final locking position, each connecting plate 52 enters the corresponding terminal accommodating chamber 43 and engages with the step 44 a of the corresponding female terminal 44. By this engagement, the movement of the female terminal 44 to the rear side is prohibited (that is, the female terminal 44 is prevented from coming off).

  As shown in FIG. 6B and FIG. 7B, in the final locking position, the lower end 55 of the spacer 50 (the pair of side plates 51) is stored inside the main body 41 (the bottom of the main body 41). Do not protrude below the wall). Therefore, in a state where the spacer 50 is in the final locking position, the mating connector 40 can be fitted into the fitting chamber 24 until the fitting is completed. In other words, the mating connector 40 can be fitted into the fitting chamber 24 in a state where it is guaranteed that the female terminal 44 is completely inserted into the terminal accommodating chamber 43.

  The mating connector 40 is a joint connector in a state where assembly is completed as shown in FIGS. 8 and 9 with a plurality of female terminals 44 inserted into the terminal accommodating chamber 43 and the spacer 50 in the final locking position. It is inserted and fitted into the fitting chamber 24 of JC. As shown in FIG. 9, the locking piece 54 of the spacer 50 does not interfere with the ridge portion 25 of the housing 20 in the fitting completed state. In other words, the presence of the locking piece 54 does not hinder the mating until the mating connector 40 is completely mated.

  In the fitting completion state, each terminal portion 11 of the bus bar 10 exposed inside the fitting chamber 24 is fitted and connected to the corresponding female terminal 44 accommodated in the mating connector 40. As a result, an electric wire conduction pattern corresponding to the type of the mating connector 40 is obtained for the plurality of wires belonging to the mating connector 40 via the corresponding bus bar 10.

  As described above, according to the connector device according to the embodiment of the present invention, the bottom surface of the guide groove (recess 45) formed on the outer wall surface of the mating connector 40 penetrates the insertion space 47 inside the mating connector 40. A hole 46 is provided, and the locking piece 54 of the spacer 50 is locked using the through hole 46. That is, the guide groove (recess 45) is also used as a portion for locking the locking piece 54. Therefore, the locking structure of the spacer 50 can be simplified as compared with the case where a portion for locking the locking piece 54 is provided separately.

  Furthermore, the mating connector 40 cannot be fitted into the fitting chamber 24 of the joint connector JC unless the spacer 50 is in the fully locked state. Therefore, the mating connector 40 can be prevented from being fitted in a state where the female terminal 44 is not sufficiently held by the mating connector 40.

  4, 5, and 7, the mating connector 40 is provided with a locking portion 48, and as shown in FIGS. 3 and 8, the housing 20 has an engaging protrusion 26. Is provided. The engagement protrusion 26 is provided at the end of a cantilever-like lock arm 27 (see FIGS. 8 and 9). Then, when the mating connector 40 is inserted (fitted) into the fitting chamber 24 of the housing 20, the locking portion 48 engages with the engaging protrusion 26, so that the mating connector 40 is connected to the housing 20. It will be held in the fitted state.
