That is, the second housing 111 is formed by filling the cavity of the mold in which the second terminal 161 is set in advance with resin. As a result, 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 each side surface of the second convex portion 112. It is integrally attached to the second housing 111 in a state of being exposed to the surface. In this case, ten second terminals 161 are arranged on the left and right at a pitch of, for example, about 0.2 [mm]. The pitch and number of the second terminals 161 can be changed as appropriate.

A second protruding end portion 122 as a mating guide portion is provided at both ends of the second housing 111 in the longitudinal direction. The second protruding end portion 122 is a thick member extending in the width direction of the second housing 111 and having both ends connected to both ends in the longitudinal direction of the second convex portion 112, and the upper surface thereof is substantially rectangular. It has a shape. Then, the second protruding end portion 122 is inserted into the fitting recess 22 of the first protruding end portion 21 included in the first connector 1 in a state where the first connector 1 and the second connector 101 are fitted. Functions as an insertion protrusion.

Further, a second reinforcing metal fitting 151 as a counterparty reinforcing metal fitting is attached to the second protruding end portion 122. The second reinforcing metal fitting 151 is arranged along the outer surface of the second housing 111 at the second protruding end portion 122, and the tip of the holding protruding piece 158 is inside the vicinity of both ends in the longitudinal direction of the second convex portion 112. It is housed and held in the second metal fitting holding recess 126 formed on the side surface.

The second reinforcing metal fitting 151 in the present embodiment is a member integrally formed by punching, bending, or the like on a metal plate, and is an elongated strip-shaped first member extending in the width direction of the second housing 111.

Next, the operation of fitting the first connector 1 and the second connector 101 having the above 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 step according to the embodiment of the present invention, and FIG. 6 shows the connector fitting step according to the embodiment of the present invention being completed. It is a figure which shows the state which was done. In addition, in FIG. 6, (a) is a perspective view of the fitted first connector and the second connector, and shows a state of being broken along the lines BB and CC in FIG. 5, (b). ) Is a front view of the fracture surface.

Here, the first connector 1 is connected to a connection pad in which the tail portion 62 of the first terminal 61 is connected to a conductive trace of a first substrate (not shown) by soldering or the like, and is connected to the substrate of the first reinforcing metal fitting 51. It is assumed that 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 board connection portion 59 of the first reinforcing metal fitting 51 is connected. The conductive trace is a power line.

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

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 matches the position of the corresponding concave groove portion 12a of the first connector 1, and the position of the second protruding end portion 122 of the second connector 101 corresponds to the fitting of the first connector 1. When the position of the recess 22 is matched, the alignment of 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 mating side, that is, in the fitting direction, the second convex portion 112 and the second protruding end portion 122 of the second connector 101 are moved. Is inserted into the concave groove portion 12a and the fitting recess 22 of the first connector 1. As a result, as shown in FIG. 6, when the fitting of the first connector 1 and the second connector 101 is completed, the first terminal 61 and the second terminal 161 are in a conductive state.

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 comes into contact, and the second contact portion 66 of the first terminal 61 and the second contact portion 166 of the second terminal 161 come into contact with each other. As a result, the conductive trace connected to the connection pad on the first board to which the tail portion 62 of the first terminal 61 is connected and the connection pad on the second board to which the tail portion 162 of the second terminal 161 is connected are connected. Conducts with the connected conductive traces.

By the way, since the first connector 1 and the second connector 101 are mounted on the first board and the second board having a large area, the operator can use the fitting surface of the first connector 1 and the fitting surface of the second connector 101. It is not possible to visually check and, and the fitting work is performed by groping. Then, since it is a fumbling, accurate alignment cannot be performed, and the position of the first connector 1 and the position of the second connector 101 may deviate from each other. For example, a state in which the second connector 101 is displaced in the longitudinal direction with respect to the first connector 1, and a state in which the fitting surface of the second connector 101 is inclined with respect to the fitting surface of the first connector 1. May become.

In such a state, when the operator moves the first connector 1 and / or the second connector 101 in the mating direction, the end wall portion 21b of the first protruding end portion 21 of any one of the first connectors 1 is pressed. The second protruding end portion 122 of any one of the second connectors 101 comes into contact with the second protruding end portion 122, and the end wall portion 21b is directed from the second protruding end portion 122 in the fitting direction, that is, from top to bottom in FIG. It will be subject to a large pressing force.

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 of the inner wall portion 21f corresponding to the end wall portion 21b are the first. 1 Since it is covered by the central guide portion 57 of the reinforcing metal fitting 51, even if a large pressing force is received from the second protruding end portion 122, the pressing pressure is applied from the outer connecting portion 52 of the first reinforcing metal fitting 51 to the substrate 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 portion 21b is not damaged or damaged.

Moreover, the central guide portion 57 of the first reinforcing metal fitting 51 has a substantially U-shaped cross section, has a large cross-sectional coefficient, and has high strength. As a result, even if the pressing force transmitted to the end wall portion 21b of the first protruding end portion 21 via the second protruding end portion 122 is large, the central guide portion 57 of the first reinforcing metal fitting 51 applies the pressing pressure. 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 damaged.

Further, the central guide portion 57 of the first reinforcing metal fitting 51 includes a slope portion 57d that is inclined at an angle. As a result, the second protruding end portion 122 that comes into contact with the central guide portion 57 slides along the slope portion 57d and is smoothly attracted and inserted into the fitting recess 22.

Further, for example, when 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 21c of the first protruding end portion 21. However, in the present embodiment, most of the upper surface 21a and the inner wall side surface 21j of the portion of the inner wall portion 21f corresponding to the side wall extension portion 21c is covered by the side guide portion 54 of the first reinforcing metal fitting 51. Even if a large pressing force is received from the second protruding end portion 122, the side wall extension portion 21c is not damaged or damaged.

Further, the side guide portion 54 of the first reinforcing metal fitting 51 includes a slope portion 54d that is inclined at an angle. As a result, the second protruding end portion 122 that comes into contact with the side guide portion 54 slides along the slope portion 54d and is smoothly attracted and inserted into the fitting recess 22.

Even when the second connector 101 is misaligned with respect to the first connector 1, the apex of the upper covering portion 57a of the central guide portion 57 and the apex of the upper covering portion 54c of the side guide portion 54 are the contact arm portions 55. Since it is located higher than the apex of the upward curved portion 55d of the above, the second protruding end portion 122 does not come into contact with the contact arm portion 55 first. Therefore, the contact arm portion 55 has flexibility and is not damaged or damaged even if the strength is low.

Further, since the apex of the upper covering portion 57a of the central guide portion 57 and the apex of the upper covering portion 54c of the side guide portion 54 are higher than the upper surface 14a of the side wall portion 14 and the upper surface 13a of the first convex portion 13. , The second protruding end portion 122 does not first come into contact with the side wall portion 14 and the first convex portion 13. Therefore, the side wall portion 14 and the first convex portion 13 are not damaged or damaged.

However, in a state where the second connector 101 is largely displaced with respect to the first connector 1, the second protruding end portion 122 does not abut on the first reinforcing metal fitting 51, but rather on the side wall portion 14 and the first convex portion 13. There is a possibility that they will come into contact first, but even in such a case, the apex of the upward curved portion 55d of the contact arm portion 55 and each portion of the first terminal 61 are the upper surface 14a and the first portion of the side wall portion 14. Since the contact arm portion 55 and the first terminal 61 are located at a position equal to or lower than the upper surface 13a of the convex portion 13, the contact arm portion 55 and the first terminal 61 are not subjected to pressing force from the second protruding end portion 122. Therefore, the contact arm portion 55 and the first terminal 61 are not damaged or damaged.

By the way, since the second housing 111 of the second connector 101 has a smaller dimension in the lateral direction, that is, in the width direction, as compared with the first housing 11 of the first connector 1, the second protruding end portion 122 has a smaller dimension. Compared with the end wall portion 21b of the first protruding end portion 21, the strength is high and the damage is less likely to occur. Therefore, the second main body portion 152, the central covering portion 157, the side covering portion 154, and the holding projecting piece 158 in the second reinforcing metal fitting 151 can be omitted as appropriate.

When the fitting of the first connector 1 and the second connector 101 is completed, the first terminal 61 and the second terminal 161 are in a conductive state, and the first reinforcing metal fitting 51 and the first reinforcing metal fitting 51 included in the first connector 1 are provided. The second reinforcing metal fitting 151 included in the two connectors 101 is in a state of being engaged with each other. As a result, the first reinforcing metal fitting 51 and the second reinforcing metal fitting 151 are in a conductive state, and the continuity of the power line is maintained.

Specifically, the second reinforcing metal fitting 151 is inserted inside the first reinforcing metal fitting 51, and the downward curved portion 55b of the left and right contact arm portions 55 of the first reinforcing metal fitting 51 is the left and right contact side plate portions of the second reinforcing metal fitting 151. Contact 155. At this time, the downward curved portion 55b is displaced downward as the second reinforcing metal fitting 151 relatively moves downward, and is also displaced outward in the width direction of the first housing 11, that is, outward. Then, due to the springiness of the contact arm portion 55 and the connecting arm portion 53 to which the contact arm portion 55 is connected, that is, due to the function as a spring portion, the surface of the downward curved portion 55b becomes the surface of the contact side plate portion 155. Be pressed.

As a result, the contact between the surface of the downward curved portion 55b and the surface of the contact side plate portion 155 is reliably maintained, so that the continuity between the first reinforcing metal fitting 51 and the second reinforcing metal fitting 151 is reliably maintained.

Here, the connecting arm 53 includes a long spring length from the base end connected to the left and right ends of the outer connecting portion 52 to the tip to which the contact arm 55 is connected, that is, the free end. Further, the free end of the connecting arm 53 is located below because it is the tip of the second connecting arm 53b bent in a substantially crank shape, and thus extends upward from the free end located below. The contact arm portion 55 is also provided with a long spring length up to the downward curved portion 55b. Therefore, the downward curved portion 55b is located at the free end of the connecting arm portion 53 and the contact arm portion 55, which are spring portions having an extremely long spring length, and the elastic displacement amount is extremely large. As a result, vibrations and shocks generated when the first board and the electronic device on which the second board is mounted are dropped or receive an external force are transmitted, and the second reinforcing metal fitting 51 is transmitted to the second reinforcing metal fitting 51. Even when the 151 is relatively displaced, the downward curved portion 55b can maintain the contact state by following the displacement of the contact side plate portion 155, so that the first reinforcing metal fitting 51 and the second reinforcing metal fitting 151 can be maintained. The continuity state with and is surely maintained, and the so-called instantaneous interruption, in which the continuity is temporarily cut off, does not occur.

As described above, even when the second connector 101 is displaced with respect to the first connector 1, the second protruding end portion 122 does not first come into contact with the contact arm portion 55, and the contact arm portion The 55 does not receive pressing force from the second protruding end 122. Therefore, the connecting arm portion 53 and the contact arm portion 55 can be made flexible, and the downward curved portion 55b can be flexibly and greatly displaced.

Further, a side guide portion 54 is connected in the middle of the connecting 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 becomes the inner convex portion 27. Since it comes into contact with the support surface 27a and the inner wall side surface 21j, the displacement is stopped. Therefore, the upper covering portion 54c does not come into contact with the upper surface 21a of the portion of the inner wall portion 21f corresponding to the end wall portion 21b, and the upper surface 21a is not damaged or damaged.

Further, since the displacement of the side guide portion 54 is stopped in the middle, the first connecting arm portion 53a of the connecting arm portions 53 cannot be displaced if it is displaced to some extent, and only the second connecting arm portion 53b can be displaced. .. Therefore, the downward curved portion 55b is a long spring portion having the entire connecting arm portion 53 and the contact arm portion 55 as the spring length until the displacement amount is within a certain range, that is, until the displacement of the lateral guide portion 54 is stopped. When the displacement amount exceeds the above range, the displacement is performed while exerting a strong spring force by a relatively short spring portion having the second connecting arm portion 53b and the contact arm portion 55 as spring lengths. As a result, the downward curved portion 55b has a large displacement amount and a strong spring force, so that the contact state with the contact side plate portion 155 can be maintained, and the first reinforcing metal fitting 51 and the second reinforcing metal fitting 51 can be maintained. The conduction state with 151 is surely maintained, and the so-called instantaneous interruption, in which the continuity is temporarily cut off, does not occur.

As shown in FIG. 6, when the fitting of the first connector 1 and the second connector 101 is completed, the downward curved portion 55b of the contact arm portion 55 is displaced outward by the contact side plate portion 155. Therefore, the lower end portion 55c enters the contact arm portion lower end accommodating hole 28b. When moving the first connector 1 and / or the second connector 101 in the direction away from the mating side, that is, in the anti-fitting direction in order to release the fitting between the first connector 1 and the second connector 101, the first 2. A force acts on the contact arm portion 55 of the first reinforcing metal fitting 51 holding the reinforcing metal fitting 151 in the direction of pulling out upward from the first housing 11. However, since the lower end portion 55c has entered the contact arm portion lower end accommodating hole 28b and is engaged with the lower end portion 55c, the lower end portion 55c is prevented from being displaced upward, and the lower curved portion 55b is turned over. Lifting is prevented, and the contact arm 55 is the first housing 1.
It is prevented from being pulled out from 1.

As described above, in the present embodiment, the first housing 11 fitted with the second connector 101 and the second terminal 161 of the second connector 101 arranged in the first housing 11 according to the fitting. A first connector 1 having a plurality of conductive first terminals 61, 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 lateral direction of the first housing 11. The first housing 11 includes a pair of shield plate portions 58 located at the same position, and the first housing 11 has a pair of end faces 11a formed on both ends in the longitudinal direction and a pair of side surfaces 11b formed on both ends in the lateral direction. The pair of first reinforcing metal fittings 51 having a rectangular outer shape provided with the outer connecting portion 52 covering the pair of end faces 11a of the first housing 11 and the second reinforcing metal fitting of the second connector 101 according to the fitting. A contact arm portion 55 that comes into contact with the metal fitting 151 and maintains the mated state by the contact is provided, and the pair of shield plate portions 58 cover the pair of side surfaces 11b of the first housing 11 and the pair of first reinforcements. Since both ends of the metal fitting 51 (outer connecting portion 52) in the lateral direction are integrally connected to each other, one member formed by integrally connecting the pair of first reinforcing metal fittings 51 and the pair of shield plate portions 58. As a result, not only good robustness can be obtained as compared with the conventional connector in which the periphery of the connector body is shielded by a pair of shield members, but also the seam separation can be obtained. It is also possible to prevent the deterioration of the shielding performance due to the above.

Moreover, since the first reinforcing metal fitting 51 that maintains the mated state of 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 members together.

Further, the pair of first reinforcing metal fittings 51 includes a pair of connecting arm portions 53 extending from both ends of the outer connecting portion 52 in the lateral direction along the pair of side surfaces 11b of the first housing 11, and the contact arms. The portion 55 is provided at the free end of the connecting arm portion 53, and the pair of shield plate portions 58 are arranged in parallel on the outer side of the pair of connecting arm portions 53, so that the contact arm portion 55 is elastically displaced. The pair of first reinforcing metal fittings 51 can be integrally connected to each other via the pair of shield plate portions 58.

Further, since the pair of shield plate portions 58 have a substrate connecting portion 59 connected to the circuit board and the substrate connecting portion 59 is located near the outer side of the contact arm portion 55, the contact arm portion at the time of fitting. By receiving the load acting on the 55 at the substrate connecting portion 59 located near the outer side thereof, the generation of a moment (twisting force) can be suppressed.

Further, since the pair of shield plate portions 58 have the reinforcing recesses 58b extending in the longitudinal direction, the robustness can be further improved without increasing the plate thickness of the shield plate portions 58.

Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and modifications are made within the scope of the gist of the present invention described in the claims.
