As shown in FIG. 9, the socket contact 150 has a fixing piece 152 which is fixed to the socket housing 110, and a leg portion 153 which is continuous on one end side of the fixing piece 152 and protrudes outward; and a branch contact Department 154, continuous On the other end side of the fixing piece portion 152.

As shown in FIGS. 9 and 10, the fixing piece portion 152 is embedded in the thickness direction of the long side wall portion 112 in the bottom long side portions 111a and 111b of the bottom surface portion 111.

The leg portion 153 connected to the one end portion side of the fixing piece portion 152 is protruded from the lower surface of the bottom long side portion 111a of the bottom surface portion 111 in a direction away from the other end portion side (here, the front and rear direction of the socket, respectively) . The leg portion 153 is fixed to a circuit or the like of a substrate on which the socket 100 is mounted, and is electrically connected to the substrate.

The branching contact portion 154 has a pair of diverging pieces 1541, 1542 which are arms extending from the bottom long side portion 111a (111b) toward the slit 117-1 (117-2) ( The arm 156 is bent in the opposite direction to the insertion direction of the plug (corresponding to the target connector) 200, that is, in the respective figures, and is branched into two branches.

The divergent sheets 1541 and 1542 are disposed in the openings 102 (102-1, 102-2) and are elastically deformable in a direction away from each other.

The branch contact portion 154 is continuous at the other end portion of the fixing piece portion 152 and is formed to be curved upward from the arm 156 protruding from the slit 117-1 (117-2) (on the side of the opening portion 102). As such, the divergent contact portion 154 is via the arm 156. The openings 102-1 and 102-2 are disposed apart from the components of the surrounding socket 100.

The diverging sheets 1541 and 1542 have a broken cross section which extends toward the insertion direction of the plug 200 (specifically, the rod-shaped contact portion 252 of the plug contact 250) and the direction opposite to the insertion direction, and The extending directions of the long side wall portions 211 and 213 are opposite to each other. The broken section is a surface formed when the branch contact portion 154 of the socket contact 150 is divided into two branches.

The diverging pieces 1541 and 1542 are respectively displaced in a direction away from each other by elastic deformation, that is, the diverging pieces 1541 and 1542 are respectively displaced toward each other in a direction away from each other. The direction in which the branch pieces 1541 and 1542 are apart from each other is orthogonal to (the intersection of) the thickness direction of the long side wall portions 112 and 113, and corresponds to the pitch direction at which the socket contact 150 is disposed.

The branch contact portion 154 is electrically deformably coupled to the plug contact 250 of the plug 200 inserted between the pair of split pieces 1541 and 1542 by elastically deforming the pair of branch pieces 1541 and 1542. Specifically, the branch contact portion 154 holds the rod-shaped contact portion 252 in a broken section of each of the pair of branch pieces 1541 and 1542, thereby being electrically connected to the rod-shaped contact portion 252. The clamping operation of the bar-shaped contact portion 252 by the diverging pieces 1541 and 1542 of the divergent contact portion 154 is to position the contact 250 by the positioning means (the engaging opening portions 162, 163 and the positioning rib 130 shown in FIG. 6). The connection positions of 150 and 150 are performed at the same time.

Further, in the branch contact portion 154, at the front end portion of the branch pieces 1541 and 1542, that is, at the front end portion of the branch contact portion 154, a tapered surface 1541a which is lowered toward the respective branch pieces 1541 and 1542 is formed. 1542a. The wedge faces 1541a and 1542a are respectively close to each other in the insertion direction from the front end (upper end). Further, the tip end portions of the branch pieces 1541 and 1542 together with the wedge surfaces 1541a and 1542a form claw portions 1541b and 1542b that protrude toward the respective branch pieces 1541 and 1542. The branch contact portion 154 is configured such that the rod-shaped contact portions 252 sandwiched by the fins 1541b and 1542 are held in the opposite direction to the insertion direction (upward direction) by the claw portions 1541b and 1542b, and are not easily accessible. The divergent pieces 1541, 1542 are separated.

As shown in FIG. 10, the pair of branch pieces 1541 and 1542 are disposed to face the positioning ribs 130 which are arranged side by side in the longitudinal direction (pitch direction). Specifically, the wedge-shaped surfaces 1541a and 1542a of the front ends of the pair of divergent sheets 1541 and 1542 are disposed at positions overlapping with respect to the front surface of the guide wedge-shaped surface portions 135 and 134 of the positioning rib 130. In front view, the degree of inclination of the tapered faces 1541a, 1542a of the leading ends of the diverging sheets 1541, 1542 is substantially the same as the inclination of the guiding wedge-shaped faces 135, 134 of the positioning ribs 130 which are arranged side by side in the spacing direction.

In other words, in a front view, the positioning ribs 130 are disposed between the branch contact portions 154 adjacent to each other in the pitch direction. Further, the positioning rib 130 overlaps the guide wedge-shaped surface portion 134 on the left side in the drawing on the right side wedge-shaped surface 1542a of one of the adjacent branch contact portions 154, and the right side in the figure The guiding wedge-shaped surface portion 135 overlaps the wedge-shaped surface 1541a disposed on the left side of the other adjacent branch contact portion 154 adjacent to each other.

Further, in the present embodiment, the socket contact 150 is integrally formed in the socket housing 110 by insert molding.

The operation when the socket 100 is fitted to the plug 200 in the above-described connector device 10 will be described.

<Fitting of the socket connector 100 and the plug connector 200>

Fig. 11 is a cross-sectional view showing the main part of the fitting operation of the socket connector and the plug connector. 11A to 11E show a series of flows of the fitting operation. Further, in Fig. 11, the positioning rib 130 is cut in the longitudinal direction to view the opposite branch contact portion 154. Further, Fig. 12 is a cross-sectional view showing the main part of the fitting operation of the socket connector and the plug connector.

First, as shown in FIG. 11A, the engaging convex portions 215b, 216b of the protruding portions belonging to the short side wall portions 215, 216 which are separated in the longitudinal direction (the horizontal direction in the drawing) of the plug 200 are respectively inserted into the socket 100, respectively. The engaging opening portions 162 and 163 of the short side wall portions 115 and 116. At this time, the wedge-shaped surface portions 217 and 218 of the engaging convex portions 215b and 216b of the short side wall portions 215 and 216 of the plug 200 are respectively moved along the upper end edges of the short side wall portions 115 and 116 to be guided to the engaging opening portion. 162, 163. For example, as shown in Figure 12A, even if the plug The short side wall portion 215 of the 200 is biased to the left with respect to the short side wall portion 115 of the socket 100, and the short side wall portions 115, 116 of the socket 100 are also slid by the wedge-shaped surface portions 217, 218.

By the engagement of the engaging convex portions 215b and 216b with the engaging opening portions 162 and 163, the plug 200 is roughly guided to the connection position of the mutual contacts 150 and 250 with respect to the socket 100 by mutual outer shape. .

Next, the engaging convex portions 215b and 216b of the two short side wall portions 215 and 216 of the plug 200 are inserted into the engaging opening portions 162 and 163 of the short side wall portions 115 and 116 (see FIG. 11B).

The insertion of the engaging convex portions 215b and 216b toward the engaging opening portions 162 and 163 is such that when the socket 100 and the plug 200 are fitted, the socket 100 and the plug 200 are positioned to each other by the mutual shape 150, 250 connection positions to each other.

Further, the plug 200 is inserted into the socket 100 in the insertion direction (here, from above). Thus, as shown in FIG. 11C and FIG. 12B which is a partial enlarged view of FIG. 11C, the plug contacts 250 (specifically, the rod-shaped contact portions 252) of the plug 200 are inserted between the positioning ribs 130. Furthermore, when the plug contact 250 (in detail, the rod contact portion 252) is inserted, as shown in FIG. 11D, the positioning rib 130 is guided to the branch contact portion 154 by the guiding wedge portions 134, 135. Between a pair of divergent sheets 1541, 1542.

Fig. 12C is a partially enlarged view showing the rod-shaped contact portion 252 and the branch contact portion 154 in Fig. 11D.

As shown in FIG. 12C, the plug contact 250 (the rod-shaped contact portion 252) is favorably guided to the pair of divergent pieces 1541 of the branch contact portion 154 by the guiding wedge-shaped portions 134, 135 of the positioning rib 130, respectively. Between 1542.

Further, when the plug 200 is inserted into the socket 100 side in the insertion direction (here, from above), the plug contact 250 (the rod contact portion 252) is inserted into the pair of divergent pieces 1541 of the branch contact portion 154. Between 1542. That is, the rod-shaped contact portion 252 is inserted between the fracture faces of the pair of divergent pieces 1541 and 1542 which face each other. Along with this, the pair of divergent pieces 1541 and 1542 are displaced in a direction away from each other (longitudinal direction, pitch direction).

Next, as shown in FIG. 11E, the plug contact 250 (the rod-shaped contact portion 252) is inserted into the proximal end side between the pair of divergent sheets 1541 and 1542. Thereby, as shown in FIG. 13, the rod-shaped contact portion 252 is held by the fracture surface of the divergent pieces 1541 and 1542 by the restoring force of the divergent pieces 1541 and 1542, and is supported by the claw portion 1541b, The 1542b is clamped in a way that does not separate. Thereby, the plug contact 250 is connected to the socket contact 150 to be conductive.

According to the connector device 10 of the present embodiment, the socket housings 110 are formed with the engagement opening portions 162 and 163, and the engagement opening portions 162 and 163 are inserted into the connector. The engagement projections 215b and 216b belonging to a part of the plug 200 are engaged with each other to position the connection positions of the contacts.

Further, the positioning rib 130 formed in the socket housing 110 is inserted into the opening portion 230 of the plug 200, and the rod-shaped contact portion 252 is guided to the socket contact 150.

In this way, the connection positions of the contacts 150 and 250 of the socket 100 and the plug 200 are mutually correct by the two portions of the engaging mouth portions 162, 163 and the positioning ribs 130 in a manner that does not burden. The ground is positioned.

Figure 14 is a cross-sectional view showing a portion of the line D-D of Figure 11E. As shown in FIG. 14, the long side wall portions 211, 212 of the plug 200 are located on the bottom long side portions 111a, 111b of the socket 100, and are formed on the long side wall portions 112, 113 of the socket 100 and the long side wall portions 112, respectively. And 113 is fitted between the opposing branch portions 154. Further, the center beam portion 213 is fitted between the positioning ribs 130-1 and 130-2.

The socket contact 150 has a branch contact portion 154, and the branch contact portion 154 includes a pair of branch pieces 1541, 1542 attached to the socket housing 110 at the opening portion 102-1, The 102-2 is disposed so as to be branched into two branches in a direction opposite to the insertion direction of the plug 200, and is elastically deformable in a direction away from each other. Divergent contact unit 154 When the connection position is positioned by the engagement opening portions 162 and 163, the rod-shaped contact portion 252 inserted between the pair of branch pieces 1541 and 1542 is held in contact by the elastic pressure at the time of recovery by elastic deformation. The rod-shaped contact portion 252 extends horizontally in the thickness direction of the long-side wall portions 112 and 113. Further, when the branch contact portion 154 is positioned at the connection position of the plug contact 250 of the plug 200 by the positioning rib 130, the rod-shaped contact portion 252 inserted between the pair of branch pieces 1541 and 1542 is held to be conductive. .

As described above, in the present embodiment, the opposing faces (broken sections) of the pair of branch pieces 1541 and 1542 which are branched in the opposite directions with respect to the insertion direction in the branch contact portion 154 are sandwiched by the plug 200 in the pitch direction. Rod-shaped contact portion 252. Thereby, the configuration of the contact on the plug 200 side can be simplified by being formed into a rod shape sandwiched by the pair of branch pieces 1541 and 1542. That is, unlike the conventional connector device for electrically connecting the substrates to each other, there is no need for the convex portion of the plug corresponding to the insertion depth of the socket in order to reliably connect the contacts of the plug and the socket. The protruding length ensures a predetermined length.

Fig. 15 is a view showing the fitting of the plug 2 of the connector device 1 of the comparative example to the socket 3. The connector device 1 shown in FIG. 15 is configured such that a convex portion 2b having a plug contact on the outer surface of the plug 2 is inserted into a U-shaped groove-shaped conductive portion of the socket contact 4 in the opening portion 3a of the socket 3. The inside of 4a is connected to the exposed portion 2a of the plug contact in a state of being moved in a direction separating from the side wall 5 of the socket 3.

In the connector device 10 of the present embodiment shown in FIG. 14, the diverging pieces 1541 and 1542 are sandwiched by one of the directions orthogonal to the rod-shaped contact portion 252 for insertion from above and extending substantially horizontally. Rod-shaped contact portion 252. Therefore, it is not necessary to form a structure in which the insertion depth of the plug side is ensured and the length is divided, and the deformation area of the contact on the socket side of the contact on the plug side is received to improve the engagement force of the mutual contacts. . Unlike the insertion depth a of the configuration of the comparative example of Fig. 15, the length b < a in the insertion direction can be made, that is, the height of the connector device can be lowered. That is, it is possible to achieve lightness and thinness.

As described above, according to the present embodiment, it is possible to reduce the thickness of the electronic device body to which the connector device 10 is attached. Further, unlike the conventional U-shaped groove-shaped conductive portion, it is not necessary to secure the length in the direction in which the contact on the socket contact side is separated from the side wall in order to secure the contact pressure with the contact of the outer surface of the convex portion. As described above, the connector device 10 of the present embodiment can be electrically connected stably with a simple configuration, and can be reduced in size, thickness, and size.

Further, the engaging opening portions 115 and 116 sandwich the opening portions 102-1 and 102-2, and are disposed apart from each other in a direction in which the pair of branch pieces 1541 and 1542 are apart from each other, and the engaging convex portion 215b of the plug 200 in the insertion direction, 216b snaps. It is only necessary to engage the engagement projections 115 and 116 with the engagement projections 215b and 216b of the plug 200 to roughly position the connection positions of the contacts 150 and 250.

The positioning rib 130 is opposed to the branch contact portion 154 in a direction orthogonal to a direction in which the pair of branch pieces 1541 and 1542 are apart from each other, and is separated from the bottom surface portion 111 for partitioning the openings 102-1 and 102-2. The arrangement is protruded and inserted into the opening portion (engagement recess) 230 of the plug 200 to perform positioning of the connection positions of the contacts 150, 250 with each other.

Thereby, when the socket 100 and the plug 200 are inserted and fitted, the mutually corresponding contacts 150 and 250 can be connected easily, correctly, and once.

In addition, the socket 100 and the plug 200 integrally form the contacts 150, 250 to the socket housing 110 and the plug housing 210 by insert molding. In particular, the branch contact portion 154 is disposed at a position suspended in the openings 102-1 and 102-2, that is, at a position separated from the surrounding constituent body. Thereby, the branch contact portion 154 is provided in the socket housing 110 by insert molding without requiring resin to be attached. Therefore, unlike the conventional technique, it is possible to improve the productivity without assembling the manual work required in the case where the complex shaped joints such as the bellows are incorporated into the casing.

Further, the branch contact portion 154 includes a pair of branch pieces 1541 and 1542, and the pair of branch pieces 1541 and 1542 are disposed in a position suspended in the openings 102-1 and 102-2, that is, disposed in the surrounding area. The positions at which the bodies are separated are branched into two branches in a direction opposite to the insertion direction of the plug 200. Thereby, when the plug 200 is inserted into the socket 100 to fit the two, The deviation from the insertion direction in the vertical direction can be followed by elastic deformation, and the connection with the plug contact 250 can be held in a stable state.

Further, in the socket 100, the positioning rib 130 is disposed at a position sandwiching the socket contact 150 with each of the long side wall portions 112, 113. Thereby, when the plug 200 is inserted, the plug 200 does not enter the openings 102-1 and 102-2 in which the socket contacts 150 are disposed, and deformation due to the contact of the plug 200 can be prevented.

Further, the plug contacts 250-1 and 250-2 are configured to be bridged between the long side wall portions 211 and 212 facing the center beam portion 213, but may be only from the center beam portion 213 or the long side wall. The cantilevered structure in which the portions 211, 212 protrude. In this case, the plug contacts 250 (250-1, 250-2) are supported by the protruding central beam portion 213 or the long side wall portions 211, 212.

Specifically, the rod-shaped contact portion 252A is a broken section of the branch contact portion 354 which is formed by splitting into two branches in a direction opposite to the insertion direction of the rod-shaped contact portion 252A in the socket contact 350 (Fig. The faces of the bifurcation pieces 3541 and 3542 shown in Fig. 25 are opposed to each other in a conductive manner. At this time, since the corner portion of the lower portion of the rod-shaped contact portion 252A having a rectangular cross section is formed in an R-shaped U-shape, it is suitable for surface contact with the branch surface (broken section). Further, even if the lower portion of the rod-shaped contact portion 252A is formed as a section V The word can also achieve the same effect.

Further, the portion that is continuous with the rod-shaped contact portion 252A and protrudes from the outer surface of the long-side wall portions 21 and 22 toward the front-rear side constitutes the leg portion 254A. The leg portion 254A is fixed to a circuit or the like of the substrate and can be electrically connected to the substrate. Further, the plug contact 250A in the present embodiment is integrally molded to the plug housing 210A by insert molding. The leg portion 254A is formed in a shape in which the surface side mounted on the substrate is notched. When the plug contact 250A is inserted into the plug housing 210A, the runners are formed in a plurality of identically arranged states via the respective leg portions 254A. Next, when the connected leg portion 254A is cut after the molding, in order to reduce the size of the plug 200A itself, it is desirable to cut the plurality of leg portions 254A from the surface of the runner opposite to the mounting surface. Thus, even if a burr is generated at the time of the cutting, since the burr is located in the notch portion, the mounting surface of the leg portion 254A can ensure a flat state. Moreover, this configuration can also be applied to the socket contact 350 of the socket 100A.

The leg portion 353 connected to one end side of the fixing piece portion 352 protrudes from the lower surface edge portion of the long side wall portions 12 and 13 in a direction away from the long side wall portions 12 and 13 (here, the socket 100A) Front and rear direction). The leg portion 353 is fixed to a circuit or the like on which the substrate of the socket 100A is mounted, and is electrically connected to the substrate.

The branch contact portion 354 is formed continuously from the lower end of the partition surface of the long side wall portions 12 and 13 toward the front end of the arm 356 extending in the openings 102A-1 and 102A-2.

The branch contact portion 354 is provided to be bent from a distal end of the arm 356 in a direction opposite to the insertion direction of the plug (corresponding to the target connector) 200A (also referred to as an upward direction, also referred to as an extraction direction). Further, the arm 356 is formed continuously from the other end portion of the fixing piece portion 352. Thereby, the branch contact portion 354 is disposed in the openings 102A-1 and 102A-2 via the arm 356 so as to be separated from the constituent body of the surrounding socket 100A.

As shown in FIG. 22, FIG. 23, and FIG. 25, the branch contact portion 354 has a pair of branch pieces 3541 and 3542, and the pair of branch pieces 3541 and 3542 are oriented from the arm 356 to the plug (corresponding to the target connector) 200A.

The divergent sheets 3541 and 3542 have broken sections 35a and 35b (see FIG. 25), and the broken sections 35a and 35b are inserted in the direction of the plug 200A (specifically, the rod-shaped contact portion 252A of the plug contact 250A). And extending in a direction opposite to the insertion direction, and the extending directions of the long side wall portions 211 and 213 are opposed to each other. The fractured sections 35a and 35b are formed by, for example, cutting a portion of the conductive plate-like material when the socket contact 350 is formed, and dividing the branch contact portion 354 into two branches. surface.

The divergent sheets 3541 and 3542 are disposed in the opening portions 102A (102A-1, 102A-2) and are elastically deformable in a direction away from each other. Specifically, as shown in FIG. 25, the divergent pieces 3541 and 3542 are respectively displaced in the direction away from each other by elastic deformation, that is, the mutually opposite fracture faces 35a, 35b of the divergent pieces 3541 and 3542 are mutually opposite. Move away from the direction. The direction in which the diverging pieces 3541 and 3542 are apart from each other is the longitudinal direction of the socket 100A orthogonal to (intersecting) the thickness direction of the long side wall portions 12 and 13, and corresponds to the direction in which the socket contacts 350 are disposed.

The branch contact portion 354 is elastically deformed to sandwich the plug contact 250A of the plug 200A inserted between the pair of split pieces 3541 and 3542 by a pair of split pieces 3541 and 3542 (refer to Figure 18 and Figure 19). Specifically, the branch contact portion 354 sandwiches the plug contact 250A with the broken sections 35a and 35b of each of the pair of branch pieces 3541 and 3542. The rod-shaped contact portion 252A (see FIG. 19) is connected to the rod-shaped contact portion 252A in an electrically conductive manner. The pinching operation of the bar contact portion 252A by the diverging pieces 3541 and 3542 of the divergent contact portion 354 is to position the contacts 250A and 350 by the positioning means (the engaging opening portions 162A and 163A shown in FIG. 22). When connecting the location.

Further, in the branch contact portion 354, the front end portions of the branch pieces 3541 and 3542, that is, the front end portions of the branch contact portions 354 are formed with wedge-shaped surfaces 3541a and 3542a which are lowered toward the respective branch pieces 3541 and 3542. The wedge faces 3541a and 3542a are close to each other in the insertion direction from the front end (upper end). Further, the front end portions of the divergent pieces 3541 and 3542 having the tapered surfaces 3541a and 3542a constitute hook portions 358 and 359 which protrude toward the mutually different branch pieces 3541 and 3542.

The hook portions 358 and 359 have hook faces 358a and 359a which are attached to the upper surface of the rod-shaped contact portion 252A (with the insertion direction) when the rod-shaped contact portion 252A of the plug contact 250A is held. The surface on the opposite side of the side surface is in contact with each other, and in detail, it is in contact with the upper end surface of the rod-shaped contact portion 252A.

The hook faces 358a, 359a of the hook portions 358, 359 are respectively cut by a part (the lower portions of the hook portions 358, 359) of the broken portions 35a, 35b of the branch pieces 3541, 3542 (the hollow portions 35c, 35d are formed). ) formed. Here, arcuate hollow portions (notched portions) 35c and 35d are formed.

In other words, the hollow portions 35c and 35d are formed in the fracture faces 35a and 35b, whereby the front end portions 358b and 359b of the hook faces 358a and 359a are larger than the corner portions on the upper surface side of the pin-shaped contact portion 252A that has been clamped. It is closer to the center side of the rod contact portion 252A.

Thereby, the hook portions 358 and 359 are formed so as to be in contact with at least four points or more from two points on the nip side and two points on the detachment side (upper surface side) before the end portions (hook ends) 358b and 359b. Rod-shaped contact portion 252A. In the present embodiment, when the rod-shaped contact portion 252A held by the branch pieces 3541 and 3542 is moved in the direction away from the branching direction 354 in the direction opposite to the insertion direction (upward), The hooking surfaces 358a, 359a will be in contact with each other to increase the pulling force. Thereby, the rod-shaped contact portion 252A that has been clamped is not easily loosened.

Further, the hollowed portions 35c and 35d are formed to be smaller than the thickness of the rod-shaped contact portion 252A in the insertion direction, thereby preventing a decrease in the contact force with respect to the rod-shaped contact portion 252A, that is, preventing the contact of the rod-shaped contacts. The decrease in the extraction force of the portion 252A.

Further, it is also possible to design such that the front end portions 358b and 359b projecting in the opposing directions of the hook portions 358 and 359 are located closer to each other than the portions of the broken portions 35a and 35b which are not hollowed out, and are not dug. The empty broken section is orthogonal to the hook faces 358a, 359a. As described above, the corner portions on the upper surface side in the front-rear direction of the rod-shaped contact portion 252A are orthogonal to each other, which is more effective. The fruit is hung. Further, in the present embodiment, the plug contact 350 is integrally formed in the socket housing 110A by insert molding.

In other words, the distal end portions 358b and 359b that protrude toward the mutually opposing directions of the hook portions 358 and 359 are located closer to the central portion than the left and right side surfaces of the rod-shaped contact portion 252A sandwiched by the bifurcation pieces 3541 and 3542. The upper surface (upper end surface) abuts.

Thereby, as shown in FIG. 31, the plug contact 250A (specifically, the rod-shaped contact portion 252A) sandwiched by the branch contact portion 354 is hooked by the hook portions 358 and 359 even if it moves in the direction of the separation. Clamp in a way that won't break away.

In other words, the corner portions of the upper surface of the rod-shaped contact portion 252A that moves in the direction of the separation are sandwiched by the fracture faces 35a and 35b of the branch pieces 3541 and 3542, and the hook faces 358a and 359a (including the front end) are included. The portions 358b and 359b) are in surface contact, that is, hooked from the side of the drawing direction, that is, the upper side. Thereby, the rod-shaped contact portion 252A that has been clamped is not easily detached, and the plug contact 250A and the socket contact 350 are electrically connected.

As described above, in the second embodiment, the branch contact portion 354 is turned toward The opposing faces (broken sections 35a and 35b) of the pair of branch pieces 3541 and 3542 that are different in the direction opposite to the insertion direction sandwich the rod-shaped contact portion 252A of the plug 200A in the pitch direction. Thereby, the configuration of the contact on the plug 200A side can be simplified by being formed into a rod shape sandwiched by the pair of branch pieces 3541 and 3542. That is, unlike the conventional connector device for electrically connecting the substrates to each other, there is no need for the convex portion of the plug corresponding to the insertion depth of the socket in order to reliably connect the contacts of the plug and the socket. The protruding length ensures a predetermined length.

As shown in FIG. 30, the branch-shaped contact portions 252A for inserting from the upper side and extending substantially horizontally are sandwiched between the divergent pieces 3541 and 3542 in one direction of the direction orthogonal to the rod-shaped contact portion 252A. Therefore, it is not necessary to improve the engagement force of the mutual contacts in such a manner as to ensure the insertion depth of the plug side and ensure the length thereof, and to secure the deformation region of the contact on the socket side of the contact on the plug side. Composition. Unlike the insertion depth a of the configuration of the comparative example of Fig. 15, the length b < a in the insertion direction can be made, that is, the height of the connector device 20 can be lowered. That is, it is possible to achieve lightness and thinness.

As described above, according to the present embodiment, it is possible to reduce the thickness of the electronic device body to which the connector device 20 is attached. Further, unlike the conventional U-shaped groove-shaped conductive portion, it is not necessary to secure the length in the direction in which the contact on the socket contact side is separated from the side wall in order to secure the contact pressure with the contact of the outer surface of the convex portion. As described above, the connector device 20 of the present embodiment can be electrically connected stably with a simple configuration, and can be reduced in size, thin, and thin.

Further, the engaging opening portions 115 and 116 sandwich the opening portions 102A-1 and 102A-2, and are disposed apart from each other in a direction in which the pair of branch pieces 3541 and 3542 are apart from each other, and the engaging convex portion 25b of the plug 200A in the insertion direction, 26b snap. Only the engagement opening portions 115 and 116 can be engaged with the engagement convex portions 25b and 26b of the plug 200A to position the connection positions of the contacts 250A and 350.

In addition, the socket 100A and the plug 200A integrally form the contacts 350, 250A into the socket housing 110A and the plug housing 210A by insert molding. In particular, the branch contact portion 354 is disposed at a position suspended in the openings 102A-1 and 102A-2, that is, at a position separated from the surrounding constituent body. Thereby, the branch contact portion 354 is provided in the socket housing 110 by insert molding, and it is not necessary to carry out the resin. Therefore, unlike the conventional technique, it is possible to improve the productivity without assembling the manual work required in the case where the complex shaped joints such as the bellows are incorporated into the casing.

Further, the branch contact portion 354 includes a pair of branch pieces 3541 and 3542, and the pair of branch pieces 3541 and 3542 are disposed at positions suspended in the openings 102A-1 and 102A-2, that is, disposed at and around the periphery. The positions at which the bodies are separated are branched into two branches in a direction opposite to the insertion direction of the plug 200A. Thereby, when the plug 200A is inserted into the socket 100A to fit the two, the deviation from the insertion direction in the vertical direction can be followed by the elastic deformation, and the connection with the plug contact 250A can be stabilized. status Hold it underneath.

Further, the plug contacts 250A-1 and 250A-2 are configured to be spanned between the long side wall portions 21 and 22 facing the center beam portion 23, but may be only from the center beam portion 23 or the long side wall. The cantilevered structure in which the portions 21 and 22 protrude. In this case, the plug contacts 250A (250A-1, 250A-2) are supported by the protruding central beam portion 23 or the long side wall portions 21, 22.

Each of the contacts 150, 350, 250, 250A of the sockets 100, 100A and the plugs 200, 200A is formed by inserting and molding the long side wall portions 12, 13, 21, 22, 211, 212 to the contact portion and the foot portion. The portion between the portions is buried in each of the long side walls. Thereby, when the sockets 100 and 100A and the plugs 200 and 200A are mounted on the substrate, it is possible to prevent the solder flux from rising toward the contact portion side when the leg portion is fixed to the circuit by soldering. In this way, problems such as poor contact after mounting can be suppressed.

Further, in each of the embodiments, the plug contacts 250-1, 250-2, 250A-1, and 250A-2 are configured to be orthogonal to the plug housings 210 and 210A from both side faces of the center beam portions 21 and 23, respectively. The method is provided, but is not limited thereto. The plugs 200 and 200A can be folded in any direction as long as they are inserted into the sockets 100 and 100A in the direction in which the plugs 200 and 200A are inserted in the direction in which the plugs 200 and 200A are inserted, and are sandwiched by the socket contacts.

Furthermore, in each of the embodiments, the sockets 100 and 100A have been described. Corresponding to the connector, and the plugs 200 and 200A correspond to the target connector, the connector device is not limited thereto, and the connector device may be such that the sockets 100 and 100A correspond to the target connector and the plugs 200 and 200A correspond to the connector. In other words, the plug 200 may be provided with a contact having the branch contact portion having the above configuration.

The socket contact 150 in the connector device 10 of the first embodiment may be replaced with the socket contact 350 of the connector device 20 of the second embodiment. Conversely, the socket contact 350 may be replaced with the socket contact 150 of the socket 100 of the first embodiment to constitute a connector device. In this case, the connector device 10 of the first embodiment can achieve the same effects as those achieved by the socket contact 350 described in the second embodiment.

The embodiments of the present invention have been described above. Further, the above description is illustrative of preferred embodiments of the present invention, and the scope of the present invention is not limited to the above embodiments. That is, the description of the configuration of the above-described apparatus and the shape of each part is merely an example, and various modifications and additions can be made to the examples in the scope of the present invention.
