Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, 2 and 3, the USB female socket includes a shell 10 and an inner core 20, the inner core 20 is disposed in the shell 10, and the inner core 20 is provided with a plurality of welding conductive sheets 22 and is exposed outside the shell 10. The shell 10 is provided with a welding pin 12, the welding pin 12 comprises two pins 14, the heads of the two pins 14 are connected, the tails of the two pins 14 are far away from each other, the side edge of the shell 10 is further provided with a positioning sheet 16 which is horizontally arranged, and the positioning sheet 16 and a welding conducting sheet 22 are in the same horizontal position.

When soldering is performed, the housing 10 is placed on a circuit board, and the soldering conductive pieces 22 of the core 20 and the soldering pins 12 of the housing 10 are all disposed at soldering positions on the circuit board. Because the positioning plate 16 and the welding conducting plate 22 are in the same horizontal position, the positioning plate 16 can support the shell 10 placed on the circuit board, so that the shell 10 is kept horizontally placed, and the shell 10 can be stably placed during welding. And the welding pin 12 comprises two pins 14, the head parts of the two pins 14 are connected, and the tail parts are far away from each other, so that the two pins are in a fork shape, and the welding pin 12 is not easy to loosen after being fixed.

The pin 14 includes an upper section 142 and a lower section 144 connected together, the lower section 144 having a width greater than the width of the upper section 142. The width of the lower section 144 is greater than the width of the upper section 142 such that the contact end of the upper section 142 and the lower section 144 forms a step, thereby improving the stability of the welding. In this embodiment, the width of the lower segment 144 gradually decreases from top to bottom. Specifically, the lower segment 144 is triangular in shape to facilitate insertion of the lower segment 144 of the pin 14 into the weld hole.

The corner of the shell 10 is provided with a clamping groove 15, the corner of the inner core 20 protrudes to form a clamping block 24, and the clamping block 24 is matched with the clamping groove 15. When the inner core 20 is inserted into the shell 10 during installation, the clamping blocks 24 move and extend into the clamping grooves 15, and therefore the relative position between the inner core 20 and the shell 10 is limited.

The inner core 20 is provided with a retaining groove 26 penetrating through the top edge and the side edge, and a retaining sheet 13 is formed on the top edge of the shell 10 and extends inwards in an inclined manner to the retaining groove 26. When the core 20 is inserted into the housing 10, the retaining piece 13 is located in the retaining groove 26 and abuts against the inner side surface of the retaining groove 26, so that the core 20 cannot easily withdraw from the housing 10.

A plurality of elastic pieces 17 are further formed on the shell 10, one end of each elastic piece 17 is connected with the shell 10, and the other end of each elastic piece 17 is suspended and bent downwards. When the male USB connector is inserted into the housing 10, the elastic piece 17 abuts against the surface of the male USB connector, so that the male USB connector is not easy to loosen. Specifically, the elastic piece 17 includes a horizontal section 172 extending horizontally, a lower section 174 extending downwards from one end of the horizontal section, and an upturned section 176 formed by upturning from one end of the lower section. In this embodiment, the elastic pieces 17 are formed on the top surface, the bottom surface, and the opposite side surfaces of the housing.

The elastic sheet 17 is stamped to form reinforcing ribs 178. By adding the reinforcing ribs to the elastic pieces 17, the elastic pieces 17 are not easy to bend under the condition of repeated deformation.

The side edges of the housing 10 are bent outward to form guide pieces 18. When the USB male connector is inserted into the housing 10, the USB male connector may be inserted into the housing 10 along the guide piece if the USB male connector is not aligned with the opening of the housing 10.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
