The material forming the base-side housing 11 is, for example, an electric insulating material such as synthetic resin. The shape of the base-side housing 11 is not limited to the illustrated shape.

The first base contact 12 comes into contact with the first plug contact 22 when the plug connector 2 is fitted into the base connector 1. The first base contact 12 is made of a conductive material such as metal. The first base contact 12 can be formed, for example, by subjecting a metal plate-shaped piece to punching, bending, or the like. In the present embodiment, as shown in FIGS. 1 to 3, a pair of first base contacts 12 are provided at both ends in the width direction D3 of the base-side housing 11. However, the number of first base contacts 12 and the positions where they are arranged are not particularly limited.

Although the structure of the first base contact 12 is not particularly limited, in the present embodiment, the first base contact 12 is configured to be elastically deformed by the movement of the first plug contact 22 in the fitting direction D1. Specifically, as shown in FIG. 5, the first base contact 12 is capable of contacting a contact base portion 121 and a later-described first fitting portion 222 of the first plug contact 22.

The locked portion L2 is formed as a rectangular engagement hole located slightly on the extraction direction D12 side from the tip of the first plug contact 22 on the fitting direction D11 side. When the first plug contact 22 moves to a predetermined position in the fitting direction D11 and fits into the first base contact 12, the lock portion L1 that is a protrusion opens the locked portion L2 as an engaging hole. By engaging with the edge, the movement of the first plug contact 22 in the extraction direction D12 is restricted.

In the present embodiment, the pair of first plug contacts 22 are provided at both ends in the width direction D3 of the plug-side housing 21. However, the number of first plug contacts 22 and the positions where they are arranged are not particularly limited.

The second plug contact 23 comes into contact with the second base contact 13 when the plug connector 2 is fitted into the base connector 1. The second plug contact 23 is formed of a conductive material such as metal.

As shown in FIG. 11, the second plug contact 23 extends from the second connection portion 231 toward the second fitting portion 232 on the end surface of the plug-side substrate PS (in the present embodiment, the first end surface of the cutout portion N). It extends beyond F1) in the fitting direction D11. The second plug contact 23 extends away from the surface PSa of the plug-side substrate PS and the first end face F1 in the second extending region that extends beyond the first end face F1 of the plug-side substrate PS. As a result, the second plug contact 23 does not contact the surface PSa of the plug-side substrate PS, a corner between the surface PSa and the end face F1, or the first end face F1. Therefore, when the plug connector 2 is connected to the base connector 1, even if the plug-side substrate PS is a metal substrate, energization between the second plug contact 23 and the plug-side substrate PS is suppressed. ..

The shape of the second plug contact 23 is not particularly limited as long as it has the second connecting portion 231 and the second fitting portion 232. In the present embodiment, as shown in FIG. 12, the second plug contact 23 includes a first plate-shaped portion 23a extending perpendicularly to the plug-side substrate PS and along the fitting direction D11, and a first plate-shaped portion 23a. A second plate-shaped portion 23b arranged substantially parallel to the plate-shaped portion 23a, and a third plate-shaped portion 23c that connects the first plate-shaped portion 23a and the second plate-shaped portion 23b in the width direction D3 (FIG. 9 and FIG. 14(B), etc.) and the end of the second plug contact 23 on the fitting direction D11 side faces the third plate-like portion 23c between the first plate-like portion 23a and the second plate-like portion 23b.

In the present embodiment, the second connecting portion 221 is provided on the first plate-shaped portion 23a, and the second fitting portion 232 is provided on the third plate-shaped portion 23c and the bent portion 23d.

As shown in FIG. 7, the second plug contact 23 has a smaller width in the width direction D3 than the first plug contact 22. In this case, when the connector C is provided with a plurality of second plug contacts 23 and the number of poles is increased, the plurality of second plug contacts 23 can be arranged at a narrow pitch in the width direction D3. Therefore, the size of the connector C does not increase in the width direction D3, and the connector C can be downsized even if the number of poles is increased.

As shown in FIG. 11, the second plug contact 23 is formed in a substantially plate shape in which the first plate-shaped portion 23a is arranged substantially perpendicular to the surface PSa of the plug-side substrate PS, and the first plate-shaped portion 23a is , Is also provided substantially perpendicular to the plate-like portion 22a of the first plug contact 22. As shown in FIG. 12, the second plug contact 23 has a narrower width on the extraction direction D12 side than on the fitting direction D11 side, and the second plug contact 23 is formed at the end on the extraction direction D12 side. The dimension of the width direction D3 of 23 is only the thickness of the first plate-shaped portion 23a.

More specifically, as shown in FIGS. 11 and 12, the first plate-shaped portion 23a is removed from the base portion B housed in the plug-side housing 21 and the outside of the plug-side housing 21 from the base portion B.

And have. The lower end of the bridge portion E2 is separated from the surface PSa of the plug-side substrate PS, and the end of the base B on the extraction direction D12 side is separated from the end face (first end face F1) of the plug-side substrate PS. When the second plug contacts 23 have such a configuration, with respect to the distance between the adjacent second plug contacts 23 in the width direction D3, the distance between the second connection portions 231 on the extraction direction D12 side is It is wider than the distance between the second fitting portions 232 on the fitting direction D11 side. Therefore, even if the plurality of second plug contacts 23 are arranged at a narrow pitch, it is possible to secure a certain distance in the width direction D3 between the plurality of second connection portions 231 connected to the contact pads CP. Therefore, when the solder connection is performed, it is possible to prevent the solder from coming into contact with the adjacent contact pad CP and causing the conduction failure.

The second connection portion 231 provided on the first plate-shaped portion 23a is soldered to the contact pad CP provided near the first end face F1 of the cutout portion N of the plug-side substrate PS. In the present embodiment, the second connection portion 231 is the lower end of the standing portion E1 of the first plate-shaped portion 23a that faces the surface PSa of the plug-side substrate PS. The contact pad CP to which the second connection portion 231 provided in the upright portion E1 is connected is formed with a dimension in the width direction D3 corresponding to the plate thickness of the first plate-shaped portion 23a. Therefore, in the present embodiment, the dimension of the contact pad CP connected to the second plug contact 23 in the width direction D3 does not increase.

The first plate-shaped portion 23a, the second plate-shaped portion 23b, and the third plate-shaped portion 23c have a C-shaped cross section to enhance the strength of the second plug contact 23. As shown in FIG. 12, the second plate-shaped portion 23b has substantially the same shape as the base B of the first plate-shaped portion 23a, and the end portion of the second plate-shaped portion 23b on the extraction direction D12 side. Is separated from the first end face F1 of the plug-side substrate PS, as shown in FIG. The third plate-shaped portion 23c connects the first plate-shaped portion 23a and the second plate-shaped portion 23b, and at the end on the fitting direction D11 side, the lower surface of the third plate-shaped portion 23c is the second fitting. It constitutes a part of the section 232. Specifically, the lower surface of the third plate-shaped portion 23c is configured to contact the second arm 132 of the second base contact 13 via the slit SL of the covering portion 211 at the end portion on the fitting direction D11 side. Has been done.

The bent portion 23d constitutes a part of the second fitting portion 232 together with the third plate-shaped portion 23c in the present embodiment. Specifically, the bent portion 23d is configured to come into contact with the first arm 131 of the second base contact 13 via the slit SL of the covering portion 211. In the present embodiment, the second plug contact 23 having the first plate-shaped portion 23a, the second plate-shaped portion 23b, the third plate-shaped portion 23c, and the bent portion 23d is formed by bending a plate-shaped metal piece. Has been formed. Therefore, the second plug contact 23 having a complicated shape having a narrow width in the width direction D3 in the extraction direction D12 and a wide width in the fitting direction D11 can be manufactured at low cost.

As shown in FIG. 11, a part of the second plug contact 23 is housed in the above-mentioned second plug contact housing portion 213. In this embodiment, the portion of the second plug contact 23 on the fitting direction D11 side (base portion B) is housed in the plug-side housing 21, and the end portion on the extraction direction D12 side (extension portion E) is the plug-side housing 21. Exposed from. Further, the second fitting portion 232 of the second plug contact 23 on the fitting direction D11 side is exposed from the plug-side housing 21 via the slit SL.

The internal space of the second plug contact accommodating portion 213 is provided so that the second plug contact 23 can be inserted and attached in the fitting direction D11. The inner wall (upper inner wall) of the second plug contact accommodating portion 213 has an accommodating portion side engaging portion 213a with which the retaining portion 233 (see FIG. 12) provided at the base B of the second plug contact 23 engages. doing. Further, as shown in FIG. 11, a slit-shaped groove portion 214 is formed on the upper surface of the plug-side housing 21 so that the extending portion E of the second plug contact 23 can be inserted into the second plug contact accommodating portion 213. Has been done. In this way, the second plug contact 23 can be inserted in the fitting direction D11 and the second plug contact 23 can be assembled to the plug-side housing 21.

The number of second plug contacts 23 and the positions where they are arranged are not particularly limited. In the present embodiment, the plurality of second plug contacts 23 are provided between the pair of first plug contacts 22 in the width direction D3. Further, as described above, the plurality of second base contacts 13 are provided between the pair of first base contacts 12 in the width direction D3. When the contacts of the base connector 1 and the plug connector 2 have such an arrangement, the first base contact 12 and the first plug contact 22 that are wide and have high rigidity are located at both ends in the width direction D3. In addition, the second base contact 13 and the second plug contact 23, which have a small width and relatively low rigidity, have a high rigidity in the width direction D3 and a high bonding strength with respect to the substrate. Sandwiched. Therefore, for example, when the plug connector 2 is subjected to a tilting force with respect to the plug-side substrate PS, a large force is suppressed from being directly applied to the second plug contact 23. In addition, for example, when the plug connector 2 is inserted into the base connector 1, damage to the second plug contact 23 is suppressed.

As described above, in the present embodiment, the fitting between the first base contact 12 and the first plug contact 22 is made by elastically deforming the first base contact 12. The fitting between the second base contact 13 and the second plug contact 23 is also made by elastically deforming the second base contact 13. In the present embodiment, the elastic deformation directions of the first base contact 12 and the second base contact 13 are both the thickness direction D2, but the elastic deformation direction is not particularly limited.

In this embodiment, as shown in FIG. 13, when the first plug contact 22 is fitted to the first base contact 12, the first base contact 12 is elastically deformed by a predetermined amount. The first insertion force IF1 applied is the second insertion force applied to the second base contact 13 in order to elastically deform the second base contact 13 by a predetermined amount when the second plug contact 23 is fitted into the second base contact 13. It is configured to be larger than IF2. Therefore, the insertion resistance when inserting the first plug contact 22 into the first base contact 12 is larger than the insertion resistance when inserting the second plug contact 23 into the second base contact 13.

The first insertion force IF1 is a force applied when the deformation amount of the first base contact 12 from the initial state by the first plug contact 22 becomes maximum during the fitting process of the first plug contact 22. The time (timing) t1 at which the first insertion force IF1 is applied may change depending on the shapes and structures of the first base contact 12 and the first plug contact 22. In the present embodiment, at time t1, as shown in FIG. 15A, the lower surface of the first fitting portion 222 of the first plug contact 22 is located on the top of the protrusion of the lock portion L1 of the first base contact 12. It is when they are in sliding contact. Further, the second insertion force IF2 is a force applied when the amount of deformation of the second base contact 13 by the second plug contact 23 from the initial state is maximized during the process of fitting the second plug contact 23. The time (timing) t2 when the second insertion force IF2 is applied may change depending on the shapes and structures of the second base contact 13 and the second plug contact 23. In the present embodiment, as shown in FIG. 16B, the time t2 is the second fitting of the second plug contact 23 between the first arm 131 and the second arm 132 of the second base contact 13. This is when the portion 232 is fully inserted.

In the present embodiment, the contact between the first plug contact 22 and the first base contact 12 which requires the first insertion force IF1 is caused by the second insertion force IF2 during the insertion process of the plug connector 2 into the base connector 1. Occurs before the contact between the second plug contact 23 and the second base contact 13, which is necessary. When the plug connector 2 is inserted into the base connector 1, when the first base contact 12 is elastically deformed by the first plug contact 22 with a force equal to or greater than the first insertion force IF1, a second insertion force IF2 smaller than the first insertion force IF1 is obtained. The second base contact 13, which is elastically deformable by, also elastically deforms. Therefore, the second base contact 13 can be elastically deformed by using the large force required to elastically deform the first base contact 12, and the plug connector 2 can be fitted into the base connector 1 to the end. Therefore, when the plug connector 2 is inserted into the base connector 1 with a predetermined force, no additional force or the like is required for fitting between the second plug contact 23 and the second base contact 13, which is the latter half of the fitting process. The fitting is not incomplete. Therefore, incomplete fitting between the plug connector 2 and the base connector 1 can be prevented. Moreover, since the first base contact 12 and the second base contact 13 do not reach the maximum deformation amount at the same time, the insertion force of the plug connector 2 into the base connector 1 does not become large, and the insertion resistance of the plug connector 2 is reduced. Can be made smaller.

In addition, in the process of inserting the plug connector 2 into the base connector 1, the first plug contact 22 and the first base contact 22 need the first insertion force IF1 after the first plug contact 22 contacts the first base contact 12. The second plug contact 23 may be configured to come into contact with the second base contact 13 before reaching the contact position between the second plug contact 23 and the second base contact 13. In this case, the elastic deformation of the second base contact 13 by the second plug contact 23 starts before the maximum deformation amount of the first base contact 12 by the first plug contact 22. Therefore, when elastically deforming the second base contact 13, the plug connector 2 can be inserted into the base connector 1 without feeling a great resistance.

In addition, in the present embodiment, the first fitting portion 222 of the first plug connector 22 is biased from the first base contact 12 in the first thickness direction (upper side) which is one direction in the thickness direction D2. The second fitting portion 232 of the second plug connector 23 is urged from the second base contact 13 in the thickness direction D2 in the second thickness direction (lower side) opposite to the first thickness direction. ing. In this case, the biasing direction from the first base contact 12 to the first fitting portion 222 and the biasing direction from the second base contact 13 to the second fitting portion 232 are opposite in the thickness direction D2. Has become. As a result, when vibration or the like is applied to the connector C, the plug connector 2 is prevented from vibrating or rattling in the thickness direction D2 with respect to the base connector 1, and the connector C is resistant to vibration and rattling. Can be

Next, an example of the fitting operation of the connector C of this embodiment will be described. The following description of the operation is merely an example, and the connector of the present invention is not limited to the following description.

First, as shown in FIG. 1, the base connector 1 and the plug connector 2 are aligned in the fitting/withdrawing direction D1, and the plug connector 2 is moved toward the base connector 1 in the fitting direction D11. Specifically, the first plug contact 22 of the plug connector 2 is moved toward the first base contact 12, and the second plug contact 23 is moved toward the second base contact 13.

As shown in FIGS. 14A and 14B, the first plug contact 22 contacts the first base contact 12 before the second plug contact 23 contacts the second base contact 13. When an insertion force exceeding the first insertion force IF1 is applied to the plug connector 2 in the fitting direction D11, as shown in FIG. 15(A), the top part of the protruding lock part L1 of the arm part 122 of the first base contact 12 is applied. And the lower surface of the first plug contact 22 are in sliding contact with each other, the plug connector 2 moves in the fitting direction D11. At this time, the second fitting portion 232 of the second plug contact 23 contacts the second base contact 13, and the first arm 131 is slightly elastically deformed from the initial state. In this state, the elastic deformation of the second base contact 13 is not maximum.

In the states of FIGS. 15(A) and 15(B), the first insertion force IF1 larger than the second insertion force IF2 is applied. Therefore, the insertion force causes the states of FIGS. 16(A) and 16(B) to pass through. Then, the plug connector 2 can be inserted into the base connector 1 up to the fitting completed state shown in FIGS. 17A and 17B without further increasing the insertion force. Therefore, the half fitting of the plug connector 2 to the base connector 1 is suppressed. Then, as shown in FIG. 17A, since the lock portion L1 engages with the locked portion L2, the plug connector 2 is prevented from coming off from the base connector 1.

In the mating completed state in which the plug connector 2 is connected to the base connector 1, the first plug contact 22 is provided on the plug side at the peripheral portion of the notch N as shown in FIGS. 9, 11 and 17B. It is separated from the surface PSa of the substrate PS and is also separated from the second end face F2 and the third end face F3. The second plug contact 23 is separated from the surface PSa of the plug-side substrate PS and is separated from the first end face F1. Therefore, even when an aluminum substrate or the like is used as the plug-side substrate PS, a portion having an exposed non-insulated cut surface such as the cutout portion N of the plug-side substrate PS when a current flows, and the first plug It is possible to prevent electrical conduction between the contact 22 and the second plug contact 23. It is possible to prevent a defect due to electrical conduction between the first plug contact 22 or the second plug contact 23 and the plug-side substrate PS. Further, in the present embodiment, a plurality of plate-shaped second plug contacts 23 that are perpendicular to the plug-side substrate PS are provided, and the connector C has multiple poles. By using a plate-shaped second plug contact 23 perpendicular to the plug-side substrate PS and arranging a plurality of second plug contacts 22 having a width narrower than the width of the first plug contact 23 in the width direction D3 in parallel, The size of the connector C does not increase in the direction D3, and the connector C can be downsized even if the number of poles is increased. Also, the width of the plug-side substrate PS to which the plug connector 2 is connected can be reduced.

The connector of the present invention is not limited to the above embodiment. For example, the number and arrangement of the first base contact 12, the second base contact 13, the first plug contact 22, and the second plug contact 23 may be changed. For example, a plurality of second plug contacts 23 may be arranged on both sides of one first plug contact 22 in the width direction D3, or the first plug contacts 22 and the second plug contacts 23 may be alternately arranged in the width direction D3. It may be provided.

Further, in the present embodiment, the cutout portion N is formed in the plug-side substrate PS, but the cutout portion N may not be formed.

Further, in the present embodiment, the first plug contact 22 is formed longer than the second plug contact 23, but the first plug contact 22 may have the same length as the second plug contact 23, It may be shorter than the second plug contact 23. In that case, the portions where the first base contact 12 and the second base contact 13 contact the first plug contact 22 and the second plug contact 23 may be adjusted depending on the purpose.
