Description

Board-to-Board Plug Connectors

technical field

The utility model belongs to a line connector, in particular to a board-to-board plug connector.

Background technique

As shown in FIG. 9 , the known U.S. Patent No. 6,626,482 discloses a board-to-board plug connector 5 and a receptacle connector 6. The conductive terminal 50 of the plug connector 5 has a slightly vertical contact end 501 and The soldering end 502 connected to the circuit board can be electrically contacted with the U-shaped conductive terminal 60 of the receptacle connector 6 through the contact end 501 when mating. However, the known US patents have the following flaws in use:

Since the tail end of the contact end 501 is against the inner wall of the receiving groove of the plug connector 5, there is no elasticity when it is in contact with the socket connector 6, and the elasticity of the contact comes entirely from the U-shaped conductive terminal 60 of the socket connector 6. Therefore, when the plug connector 5 and the receptacle connector 6 are initially docked, the contact end 501 must overcome the static friction of the U-shaped conductive terminal 60 before it can be inserted smoothly. There is a lot of friction and it is easy to cause scratches. Therefore, not only the butt joint force is large in use, but also the friction between the conductive terminal and the conductive terminal is high.

Contents of the invention

The purpose of the utility model is to provide a board-to-board plug connector which can be docked with low insertion force and can reduce mutual friction between conductive ends.

The utility model includes an insulating body and several conductive terminals; the insulating body is a flat elongated body, which has a docking port, a docking surface located on the opposite outer side of the docking port, a joint surface adjacent to the docking surface, and a joint surface arranged on the joint surface and the joint surface. There are several receiving holes for accommodating conductive terminals and a push-in part integrally extended from the front edge of the docking port and adjacent to the receiving holes; the conductive terminals are housed in the receiving holes of the insulating body, which have a contact part and a welding part; the frontmost part of the contact part The edge is close to the pushing part of the insulating body; the welding end of the welding part is horizontal.

in:

The pushing portion of the insulating body is provided with an inclined surface adjacent to the leading edge of the contact portion with a guiding function.

The contact portion of the conductive terminal is provided with a fixed end for assembly in the receiving hole.

A curved arc with guiding effect is formed between the leading edge of the contact portion of the conductive terminal and the fixed end.

Because the utility model includes an insulating body and several conductive terminals; the insulating body is a flat elongated body, which has a docking port, a docking surface located on the opposite outer side of the docking port, a joint surface adjacent to the docking surface, and a joint surface arranged on the joint surface and joint Between the surfaces are several receiving holes for accommodating conductive terminals and a push-in part integrally extended from the front edge of the docking port and adjacent to the receiving holes; the conductive terminals are housed in the receiving holes of the insulating body, which have contact parts and welding parts; The leading edge is close to the pushing part of the insulating body; the welding end of the welding part is horizontal. When the board of the utility model is plugged into the socket connector, the push-in part first abuts against the contact convex arc of the contact part of the conductive terminal of the socket connector, and the push-in part and the socket connector are made of metal by the insulating material. The low friction coefficient of the contact part of the contact part of the conductive terminal of the material and the curved arc of the contact part overcome the static friction of the conductive terminal of the contact part socket connector, so that the subsequent insertion is smoother. After overcoming the static friction force, the utility model The contact portion of the conductive terminal can be smoothly butted with the contact portion of the conductive terminal of the socket connector, and during the docking process, since the friction between the two contact portions has been reduced, there will be no scratches or wear. Not only can it be docked with low insertion force, but also reduce the friction between the conductive ends, so as to achieve the purpose of the utility model.

Detailed ways

As shown in FIG. 1 and FIG. 2 , the board-to-board plug connector 1 of the present invention includes an insulating body 2 and several conductive terminals 3 .

The insulating body 2 is a prolate body, which has a docking port 20, a docking surface 21 located on the opposite outer side of the docking port 20, a joint surface 22 adjacent to the docking surface 21, and is arranged between the docking surface 21 and the joint surface 22 to accommodate A plurality of receiving holes 23 of the conductive terminal 3 and a pushing portion 24 integrally extended from the front edge of the docking port 21 and adjacent to the receiving holes 23 .

The conductive terminal 3 has a contact portion 30 and a welding portion 31 . The leading edge of the contact portion 30 is adjacent to one end of the inclined surface 241 of the pushing portion 24 of the insulating body 2, and the contact portion 30 is provided with a fixed end 32 for assembly in the receiving hole 23. With the curved arc 33 having a guiding effect, the welding end 310 of the welding portion 31 is in a horizontal shape by surface adhesive welding.

As shown in Fig. 3, Fig. 4, and Fig. 5, the socket connector 3 plugged with the board-to-board plug connector 1 of the present invention is provided with a docking groove 40 corresponding to the plugging of the utility model, and the bottom of the docking groove 40 There is a concave part 401 for accommodating the pushing part 24 of the insulating body 2 after plugging. The conductive terminal 41 of the receptacle connector 4 has a contact portion 42 that is an elastic arm, and a contact convex arc 421 with a guiding effect is formed between the contact portion 42 and the front edge, that is, the contact portion 42 has appropriate elastic flexibility. Movement on one side produces deformation.

As shown in Figure 5 and Figure 6, when the board-to-board plug connector 1 of the present invention is plugged into the socket connector 4, the inclined surface 241 of the pushing part 24 first abuts against the conductive terminal 41 of the socket connector 4. On the contact convex arc 421 of the contact portion 42, the contact portion 42 of the contact portion 42 contacting the convex arc 421 of the conductive terminal 41 made of metal material by the inclined surface 241 of the insulating material pushing portion 24 and the socket connector 4 has a low coefficient of friction and contact The curved arc 33 of the part 30 overcomes the static friction of the conductive terminal 42 of the socket connector 4 of the contact part, so that the insertion of the subsequent plug connector 1 is smoother. As shown in Figures 7 and 8, it can be clearly seen that after overcoming the static friction force, the contact portion 30 of the conductive terminal 3 of the plug connector 1 can be smoothly butted with the contact portion 42 of the conductive terminal 41 of the socket connector 4, and the During the docking process, since the friction between the two contact parts 30 and 42 has been reduced, no scratches or wear will occur.
