[0019]

Referring to FIGS. 1 through 4, the electrical connector of the preferred embodiment of the present invention includes an insulative housing 1 and a plurality of terminals 2 made of metal. This electrical connector can be applied to battery connectors, electronic card connectors, and the like.

[0020]

The insulative housing 1 has an abutting surface 1a, a welding surface 1b opposed to the abutting surface 1a, and a plurality of terminal grooves 11. The terminal slots 11 are all located on the same side of the insulative housing 1. Each of the terminal slots 11 accommodates the corresponding terminals 2. Therefore, the electrical connector of this embodiment is an electrical connector in which the terminals are arranged in a single row. There is an opening 12 above the terminal slot 11, and the abutting surface 1a communicates with the terminal slot 11 through the opening 12, and a part of the terminal 2 received in the terminal slot 11 extends from the opening 12 to the mating surface 1a for connection with the electrical connector (not shown). The terminals are joined, so the electrical connector of the present embodiment is an electrical connector in which the terminals are exposed and arranged in a single row. A lower portion of the opposite side walls 13 of the terminal groove 11 is recessed in the longitudinal direction of the side wall, and a shoulder portion 15 is formed on each of the two side walls 13 of the terminal groove 11.

[0021]

As shown in FIG. 4, the terminal 2 has a base portion 21, an elastic portion 22 formed by bending a rear end 21b of the base portion 21 rearward and upward, and a front end portion 22a of the elastic portion 22 extending forwardly and then inclined upwardly and upwardly. The bent portion 23, the contact portion 24 formed by bending the front end 23a of the bent portion 23 downwardly from the circular arc, and the abutting portion formed by the front end 24a of the contact portion 24 extending obliquely downward to the position above the base portion 21 and then bent backward 25. A solder fillet portion 26 connected to the front end 21a of the base portion 21. In the present embodiment, the elastic portion 22 is obliquely extended downward from the rear end 21b of the base portion 21 and then bent upwardly, so that the joint between the base portion 21 and the elastic portion 22 assumes a bent structure. The elastic portion 22 can be compressed and elastic, and the bent portion 23 also provides elasticity.

[0022]

The opposite side edges of the base portion 21 of the terminal 2 each extend to form a wing portion 27, and each of the wing portions 27 is fitted into each of the guide grooves 14, and the terminal 2 is positioned in the terminal groove 11. In the present embodiment, the wing portions 27 of the respective terminals 2 are formed into two pairs of latching portions 271 by tearing, and the latching portions 271 are correspondingly engaged with the respective guide grooves 14 to position the terminals 2 in the terminal slots 11. The holding portion 271 can increase the holding force of the wing portion 27 after being inserted into the guiding groove 14 to ensure the stability of the terminal 2 positioned in the terminal slot 11; and the height of the guiding groove 14 can be increased to be used on the insulating body 1 The mold core forming the guide groove 14 can be thick, convenient for processing and molding, and the mold has a long life. However, this embodiment is not intended to limit the present invention. For example, the front end of the wing may be bent forwardly at an angle to the base to form a catch portion. In addition, a convex package 241 may be disposed on the contact portion 24 of the terminal 2 to increase the contact capability and the conductive capability of the contact portion 24 with the mating electrical connector terminal, thereby avoiding contact failure and making signal transmission more stable.

[0023]

The opposite sides of the abutting portion 25 of the terminal 2 extend to form a lug 251. Each of the lugs 251 abuts against the lower edge 151 of the corresponding shoulder portion 15 to cause a limit function, so that the terminal 2 is positioned after the terminal slot 11 The height of the contact portion 24 of the opening 12 extending from the abutting surface 1a is uniform. In addition, one end of the contact portion 24 of the terminal 2 is connected to the bent portion 23, the other end is connected to the abutting portion 25, and the free end 252 of the abutting portion 25 is located above the base portion 21. Therefore, the electrical connector terminal 2 in this embodiment When engaged with the mating electrical connector terminal, the free end 252 of the abutting portion 25 abuts against the base portion 21, which increases the positive force and stabilizes the engagement, and allows the terminal to be less deformed and loses its elasticity.

[0024]

The terminal 2, as shown in FIG. 3, may have a surface mount technology (SMT) for the solder fillet portion 26, so that the solder fillet portion 26 is bent downward from the front end 21a of the base portion 21 and then extended forward, and can be torn. The broken molding method is formed to save the terminal plate while ensuring the solder area. At this time, the terminal groove 11 has a soldering port 16 underneath, the soldering surface 1b and the terminal slot 11 are connected by the soldering port 16, and the soldering leg portion 26 of the SMT type of the terminal 2 accommodated in the terminal slot 11 can be located at the soldering port 16 for soldering. Circuit board (not shown).

[0025]

In this embodiment, the other side of the insulative housing 1 opposite to the side on which the terminal slot 11 is provided may extend with a trapezoidal structure 17 to increase the suction area of the suction nozzle for the suction element, and to satisfy different nozzles. structure. The welding surface 1b of the insulative housing 1 can be provided with a positioning post 18 to ensure better positioning on the circuit board.
