The tail portion 162 is connected to the lower end of the main body portion extending in the left-right direction, that is, the width direction of the second housing 111, and extends outward from the second housing 111, thereby conducting the second substrate. The connection pads connected to the traces are connected by soldering or the like. The conductive trace is typically a signal line.

  Furthermore, the first contact portion 165 is a flat plate-like portion connected to the main body and extending in the vertical direction, that is, in the thickness direction of the second housing 111. The connection portion 164 is bent and connected to the first contact portion 165 and extends outward in the width direction of the second housing 111. The second contact portion 166 is a portion which is bent downward and connected to the outer end of the connection portion 164 and extends downward.

  The second terminal 161 is integrated with the second housing 111 by overmolding or insert molding. That is, the second housing 111 is formed by filling a resin into a cavity of a mold in which the second terminal 161 is set in advance. Thereby, the main body of the second terminal 161 is buried in the second housing 111, and the surfaces of the first contact portion 165, the connection portion 164, and the second contact portion 166 are fitted to the side surfaces of the second convex portion 112. It is integrally attached to the second housing 111 with the surface exposed. In this case, ten second terminals 161 are disposed on the left and right, respectively, at a pitch of about 0.2 mm, for example. Note that the pitch and number of the second terminals 161 can be changed as appropriate.

  And, at both ends in the longitudinal direction of the second housing 111, second projecting end portions 122 as mating mating guide portions are respectively disposed. The second projecting end portion 122 is a thick member that extends in the width direction of the second housing 111 and has both ends connected to both ends in the longitudinal direction of each second convex portion 112, and its upper surface is substantially rectangular. It has a shape. The second projecting end 122 is inserted into the fitting recess 22 of the first projecting end 21 of the first connector 1 in a state in which the first connector 1 and the second connector 101 are fitted. It functions as an insertion convex part.

  Further, a second reinforcing fitting 151 as a mating reinforcing fitting is attached to the second projecting end 122. The second reinforcing metal fitting 151 is disposed along the outer surface of the second housing 111 at the second projecting end portion 122, and the tip of the holding projecting piece 158 is on the inner side near both longitudinal ends of the second projecting portion 112. It is accommodated and held in the second metal fitting holding recess 126 formed on the side surface.

  The second reinforcement fitting 151 in the present embodiment is a member integrally formed by performing processing such as punching and bending on a metal plate, and an elongated belt-like third member extending in the width direction of the second housing 111. A main body portion 152, a central covering portion 157 connected to the upper end of the second main body portion 152, side covering portions 154 connected to the left and right ends of the central covering portion 157, and A holding projection piece 158 connected to one side edge, a contact side plate portion 155 connected to the other side edge of the side cover portion 154, and a board connection portion 156 connected to the lower end of the contact side plate portion 155 Is provided.

  The center cover portion 157 has a shape and a size that cover most of the upper surface of the second protruding end portion 122 in a state where the second reinforcing metal fitting 151 is attached to the second protruding end portion 122 as shown in the drawing. It is a member formed at the bottom.

  Further, the side cover 154 is a member that extends in the longitudinal direction of the second housing 111 from the left and right ends of the center cover 157 and covers the upper surface of the second convex portion 112 in the vicinity of both ends in the longitudinal direction. The contact side plate portion 155 is a member that covers the outer side surface of the second convex portion 112 in the vicinity of both ends in the longitudinal direction.

  Further, the board connection portion 156 extends outward from the second housing 111 and is connected to a connection pad connected to a conductive trace of the second board by soldering or the like. The conductive trace is typically a power line.

  The second main body portion 152, the center covering portion 157, the side covering portions 154, and the holding projection piece 158 in the second reinforcement fitting 151 can be omitted as appropriate.

  Next, an operation of fitting the first connector 1 and the second connector 101 having the above-described configuration will be described.

  FIG. 5 is a perspective view showing the positional relationship between the first connector and the second connector in the connector fitting process in the embodiment of the present invention, and FIG. 6 is the connector fitting process in the embodiment of the present invention. It is a figure which shows the state which carried out. 6A is a perspective view of the fitted first connector and the second connector, and shows a state broken along the lines BB and CC in FIG. ) Is a front view of the fracture surface.

  Here, the first connector 1 is connected by soldering or the like to a connection pad in which the tail portion 62 of the first terminal 61 is connected to the conductive trace of the first substrate (not shown), and the substrate connection of the first reinforcing bracket 51 The portion 59 is surface-mounted on the first substrate by being connected to the connection pad connected to the conductive trace of the first substrate by soldering or the like. The conductive trace connected to the connection pad to which the tail portion 62 of the first terminal 61 is connected is a signal line and is connected to the connection pad to which the substrate connection portion 59 of the first reinforcing bracket 51 is connected. The conductive traces are assumed to be power lines.

  Similarly, the second connector 101 is connected by soldering or the like to a connection pad in which the tail portion 162 of the second terminal 161 is connected to the conductive trace of the second substrate (not shown), and the substrate connection of the second reinforcing bracket 151 It is assumed that the portion 156 is surface-mounted on the second substrate by being connected to a connection pad connected to the conductive trace of the second substrate by soldering or the like. The conductive trace connected to the connection pad to which the tail portion 162 of the second terminal 161 is connected is a signal line, and is connected to the connection pad to which the substrate connection portion 156 of the second reinforcing member 151 is connected. The conductive traces are assumed to be power lines.

  First, as shown in FIG. 5, the operator sets the fitting surface of the first housing 11 of the first connector 1 and the fitting surface of the second housing 111 of the second connector 101 to face each other. The position of the second convex portion 112 of the connector 101 coincides with the position of the corresponding recessed groove portion 12 a of the first connector 1, and the position of the second projecting end portion 122 of the second connector 101 corresponds to the corresponding fitting of the first connector 1 When the position of the recess 22 is aligned, the alignment between the first connector 1 and the second connector 101 is completed.

  In this state, when the first connector 1 and / or the second connector 101 is moved in the direction approaching the other side, that is, the fitting direction, the second convex portion 112 and the second protruding end portion 122 of the second connector 101. Is inserted into the recessed groove 12 a of the first connector 1 and the fitting recess 22. Thereby, as FIG. 6 shows, when the fitting of the 1st connector 1 and the 2nd connector 101 is completed, it will be in the state which the 1st terminal 61 and the 2nd terminal 161 became conductive.

  Specifically, the second terminal 161 of the second connector 101 is inserted between the first contact portion 65 and the second contact portion 66 of each first terminal 61, and the first contact portion 65 and the first contact portion 65 of the first terminal 61 are inserted. The first contact portion 165 of the two terminals 161 is in contact, and the second contact portion 66 of the first terminal 61 and the second contact portion 166 of the second terminal 161 are in contact. As a result, the conductive trace connected to the connection pad on the first substrate to which the tail portion 62 of the first terminal 61 is connected, and the connection pad on the second substrate to which the tail portion 162 of the second terminal 161 is connected Conduction with the connected conductive traces.

  By the way, since the first connector 1 and the second connector 101 are respectively mounted on the first board and the second board having a large area, the operator can fit the fitting surface of the first connector 1 and the fitting surface of the second connector 101. And can not be visually observed, and will perform fitting work by groping. As a result, it is not possible to perform accurate alignment because it is a grooving, and the position of the first connector 1 and the position of the second connector 101 may be shifted. For example, in a state in which the second connector 101 is displaced in the longitudinal direction with respect to the first connector 1 and in which the fitting surface of the second connector 101 is inclined with respect to the fitting surface of the first connector 1 It may become.

  In such a state, when the operator moves the first connector 1 and / or the second connector 101 in the fitting direction, the end wall portion 21b of one of the first projecting end portions 21 of the first connector 1 One of the second projecting ends 122 of the second connector 101 abuts, and the end wall 21b is directed from the second projecting end 122 in the fitting direction, that is, from top to bottom in FIG. It will receive a large pressure.

  However, in the present embodiment, the first reinforcing metal fitting 51 is attached to the first protruding end portion 21 and most of the upper surface 21a and the inner wall end surface 21e of the portion corresponding to the end wall portion 21b in the inner wall portion 21f Since it is covered by the central guide portion 57 of the first reinforcing bracket 51, even if it receives a large pressing force from the second projecting end portion 122, the pressing force is applied from the outer connecting portion 52 of the first reinforcing bracket 51 to the board connecting portion. Since it is transmitted to the first substrate via 59, it is hardly transmitted to the end wall portion 21b. Therefore, the end wall 21b is not damaged or damaged.

  Moreover, the central guide portion 57 of the first reinforcing bracket 51 has a substantially U-shaped cross section, a large section modulus, and a high strength. As a result, even if the pressing force transmitted to the end wall 21b of the first projecting end 21 via the second projecting end 122 is large, the pressing force of the central guide 57 of the first reinforcing fitting 51 is It can be effectively received, and the pressing force is hardly transmitted to the end wall portion 21b. Therefore, even if the pressing force is large, the end wall portion 21b is not damaged or broken.

  Further, the central guide portion 57 of the first reinforcing bracket 51 is provided with a slope portion 57d that is inclined obliquely. As a result, the second projecting end portion 122 in contact with the central guide portion 57 slides along the slope portion 57d and is smoothly guided and inserted into the fitting concave portion 22.

  Further, for example, in a state where the second connector 101 is displaced in the width direction with respect to the first connector 1, the second protruding end portion 122 comes into contact with the side wall extension portion 21 c of the first protruding end portion 21. However, in the present embodiment, most of the upper surface 21a and the inner wall side 21j of the portion corresponding to the side wall extension 21c in the inner wall 21f are covered by the side guide 54 of the first reinforcing fitting 51, Even if a large pressing force is received from the second protruding end 122, the side wall extension 21c is not damaged or broken.

  Further, the side guide portion 54 of the first reinforcing bracket 51 includes a slope portion 54d that is inclined obliquely. As a result, the second protruding end portion 122 in contact with the side guide portion 54 slides along the slope portion 54d, and is smoothly guided and inserted into the fitting recess 22.

  Even when the second connector 101 is displaced with respect to the first connector 1, the apex of the upper cover portion 57 a of the central guide portion 57 and the apex of the upper cover portion 54 c of the side guide portion 54 are in contact arm portions 55. Therefore, the second projecting end portion 122 does not contact the contact arm portion 55 first. Therefore, the contact arm portion 55 has flexibility and is not damaged or broken even if the strength is low.

  In addition, the apex of the upper cover 57a of the central guide 57 and the apex of the upper cover 54c of the side guide 54 are higher than the upper surface 14a of the side wall 14 and the upper surface 13a of the first projection 13. The second projecting end portion 122 does not first contact the side wall portion 14 and the first convex portion 13. Therefore, the side wall part 14 and the first convex part 13 are not damaged or broken.

  However, in a state where the second connector 101 is largely misaligned with respect to the first connector 1, the second projecting end 122 does not abut the first reinforcing metal fitting 51, and the side wall 14 and the first projection 13 are Even in such a case, the top of the upper curved portion 55d of the contact arm 55 and each portion of the first terminal 61 may be in contact with the top surface 14a of the side wall 14 or the first The contact arm portion 55 and the first terminal 61 do not receive a pressing force from the second protruding end portion 122 because they are at a position equal to or lower than the upper surface 13 a of the convex portion 13. Therefore, the contact arm portion 55 and the first terminal 61 are not damaged or broken.

  By the way, since the second housing 111 of the second connector 101 is smaller in dimensions in the lateral direction, that is, in the width direction than the first housing 11 of the first connector 1, the second protruding end portion 122 is Compared with the end wall portion 21b of the first projecting end portion 21, the strength is high and it is difficult to break. Therefore, the second main body 152, the center cover 157, the side cover 154, and the holding protruding piece 158 in the second reinforcing metal fitting 151 can be omitted as appropriate.

  When the fitting between the first connector 1 and the second connector 101 is completed, the first terminal 61 and the second terminal 161 are brought into conduction, and the first reinforcing bracket 51 provided in the first connector 1 and the first The second reinforcing metal fitting 151 provided in the two connectors 101 is engaged with each other. Thereby, the 1st reinforcement metal fitting 51 and the 2nd reinforcement metal fitting 151 will be in the state connected, and the conduction | electrical_connection of an electric power line is maintained.

  Specifically, the second reinforcement fitting 151 is inserted inside the first reinforcement fitting 51, and the downward curved portions 55 b of the left and right contact arms 55 of the first reinforcement fitting 51 are the left and right contact side plate parts of the second reinforcement fitting 151. 155 is contacted. At this time, the downward bending portion 55b is displaced downward as the second reinforcing metal fitting 151 moves relatively downward, and is displaced outward in the width direction of the first housing 11, that is, outward. Then, the surface of the lower curved portion 55b is formed on the surface of the contact side plate portion 155 by the springiness of the contact arm 55 and the connection arm 53 to which the contact arm 55 is connected, that is, by the function as a spring portion. Pressed.

  Thereby, the contact between the surface of the lower curved portion 55b and the surface of the contact-side plate portion 155 is reliably maintained, so that the electrical connection between the first reinforcing bracket 51 and the second reinforcing bracket 151 is reliably maintained.

  Here, the connection arm portion 53 has a long spring length from the proximal end connected to the left and right ends of the outer connection portion 52 to the distal end to which the contact arm portion 55 is connected, that is, the free end. Further, the free end of the connection arm portion 53 is located at the lower side because it is the tip of the second connection arm portion 53b bent in a substantially crank shape, and thus extends upward from the free end located at the lower side. The contact arm 55 also comprises a long spring length up to the lower curve 55b. Therefore, the downward curved portion 55b is located at the free ends of the connection arm portion 53 and the contact arm portion 55, which are spring portions having an extremely long spring length, and the amount of elastic displacement is extremely large. As a result, vibration and impact generated when the electronic device or the like on which the first substrate and the second substrate are mounted fall or receive external force is transmitted, and the second reinforcing bracket 51 is transmitted to the first reinforcing bracket 51. Even when 151 is relatively displaced, the lower curved portion 55b can maintain the contact state by following the displacement of the contact side plate portion 155, so that the first reinforcement fitting 51 and the second reinforcement fitting 151 can be maintained. Thus, there is no occurrence of a phenomenon called so-called instantaneous interruption in which the conduction state is reliably maintained and conduction is temporarily interrupted.

  As described above, even when the second connector 101 is displaced with respect to the first connector 1, the second projecting end portion 122 does not first contact the contact arm portion 55, and the contact arm portion 55 does not receive a pressing force from the second projecting end portion 122. Therefore, the connection arm 53 and the contact arm 55 can be made flexible, and the lower curved portion 55 b can be flexibly and largely displaced.

  Further, the side guide portion 54 is connected to the middle of the connection arm portion 53, and when the side guide portion 54 is displaced downward and outward to some extent, the lower end portion 54b of the inner covering portion 54a Since the contact with the support surface 27a and the inner wall side surface 21j is made, the displacement is stopped. Therefore, the upper cover portion 54c does not contact the upper surface 21a of the inner wall portion 21f corresponding to the end wall portion 21b, and the upper surface 21a is not damaged or broken.

  Furthermore, since the displacement of the side guide 54 is stopped halfway, the first connection arm 53a of the connection arms 53 can not be displaced if it is displaced to some extent, and only the second connection arm 53b can be displaced. . Therefore, the lower curved portion 55b is a long spring portion having a spring length of the entire connection arm 53 and the contact arm 55 until the displacement amount is within a certain range, that is, until the displacement of the side guide 54 is stopped. When the displacement amount exceeds the above range, the second connection arm portion 53b and the contact arm portion 55 are displaced while exhibiting a strong spring force by a relatively short spring portion. Thereby, since the lower curved portion 55b has a large displacement amount and a strong spring force, it can maintain the contact state with the contact side plate portion 155, and the first reinforcement fitting 51 and the second reinforcement fitting can be maintained. Thus, there is no occurrence of a phenomenon called so-called momentary interruption in which the conduction state with 151 is reliably maintained and conduction is temporarily interrupted.

  As shown in FIG. 6, when the first connector 1 and the second connector 101 are completely fitted, the lower curved portion 55 b of the contact arm 55 is displaced outward by the contact side plate 155. Thus, the lower end 55c enters the contact arm lower end accommodation hole 28b. When moving the first connector 1 and / or the second connector 101 away from the other side, that is, in the opposite fitting direction, in order to release the fitting between the first connector 1 and the second connector 101, The force in the direction of pulling upward from the first housing 11 acts on the contact arm portion 55 of the first reinforcing bracket 51 that holds the two reinforcing brackets 151. However, since the lower end 55c is in a state of entering into and engaged with the contact arm lower end accommodation hole 28b, the upward displacement of the lower end 55c is prevented, and the hook of the lower curved portion 55b (turned over) Raising is prevented and the contact arm portion 55 is prevented from being pulled out from the first housing 11.

  As described above, in the present embodiment, the first housing 11 fitted with the second connector 101 and the first housing 11 are arranged, and according to the fitting, the second terminal 161 of the second connector 101 and A first connector 1 including a plurality of first terminals 61 that are electrically connected, and a pair of first reinforcing metal fittings 51 located at both ends in the longitudinal direction of the first housing 11 and both ends in the short direction of the first housing 11. The first housing 11 includes a pair of end faces 11a formed at both ends in the longitudinal direction and a pair of side faces 11b formed at both ends in the lateral direction. The pair of first reinforcement fittings 51 has an outer connection portion 52 covering the pair of end faces 11 a of the first housing 11 and a second reinforcement of the second connector 101 according to the fitting. Hardware 151 And a pair of shield plates 58 that cover the pair of side surfaces 11b of the first housing 11 and a pair of first reinforcing brackets 51 ( Since both ends in the short direction of the outer connecting portion 52) are integrally connected, the first member is formed by integrally connecting the pair of first reinforcing brackets 51 and the pair of shield plate portions 58. The surroundings of the housing 11 can be shielded, and as a result, not only good robustness can be obtained, but also the shielding performance due to the separation of the joints as compared with the conventional connector that shields the periphery of the connector body with a pair of shielding members. Can also be prevented.

  In addition, since the first reinforcing metal fitting 51 that maintains the fitted state between the first connector 1 and the second connector 101 is also used as the shield member, the structure can be simplified and the cost can be reduced by using the member in common.

  The pair of first reinforcing metal fittings 51 includes a pair of connection arm portions 53 extending along the pair of side surfaces 11b of the first housing 11 from both ends of the outer connection portion 52 in the short direction, and a contact arm. The portion 55 is provided at the free end of the connection arm 53, and the pair of shield plate portions 58 are arranged in parallel on the outer side of the pair of connection arms 53, so that the elastic displacement of the contact arm 55 is obtained. The pair of first reinforcing metal fittings 51 can be integrally connected through the pair of shield plate portions 58 while allowing the above.

  Further, the pair of shield plate parts 58 has a board connecting part 59 connected to the circuit board, and the board connecting part 59 is located near the outer side of the contact arm part 55. By receiving the load acting on 55 at the board connecting portion 59 located in the vicinity of the outer side, generation of moment (twisting force) can be suppressed.

  In addition, since the pair of shield plate portions 58 includes the reinforcing concave portion 58b extending in the longitudinal direction, the robustness can be further improved without increasing the thickness of the shield plate portion 58.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications may be made within the scope of the gist of the present invention described in the claims. It can be changed.
