Abstract

The utility model relates to a general serial bus socket, comprising a terminal seat and a casing used for covering the terminal seat. The utility model is characterized in that the general serial bus socket also comprises an elastic piece body provided with a spring arm, both side walls of the elastic piece body are respectively provided with agnails, and the terminal seat corresponding to the wall surface is respectively provided with a containing groove. Both side walls of the containing groove is correspondingly provided with a guide rail, and the elastic piece body is guided into the containing groove by the guide rail and positioned firmly by the agnails on both side walls used for being penetrated into the guide rail. The original function of the general serial bus socket can not be affected, and the manufacturing cost can be reduced effectively.

Description

The USB socket

The utility model relates to a kind of socket, relates in particular to a kind of USB socket.

The existing trend that replaces D shape connector gradually of universal serial bus connector (universalserialbusconnectors), and become the main flow of connector of new generation, as shown in Figure 1, universal serial bus connector in the past includes the plug 2 of a socket 1 and and this socket 1 phase configuration, can be reached the purpose of communicated data signal by the two binding.Please cooperate and consult Fig. 2, shown in 3, aforementioned USB socket 1 includes the terminal base 10 and the shell 11 in order to clad terminal seat 10 that are provided with terminal 100, be respectively equipped with a storage tank 101 on two sidewalls of this terminal base 10, this shell 11 generally is the housing that sheet material is bent into a rectangle through stamped, edge bends inwards into four defining flanges 13 around the front opening 12 of shell 11, and the defining flange 13 of the front opening 12 dual-sides elastic arm 14 that also extends internally in the position of corresponding storage tank 101, the front end of each elastic arm 14 roughly is affixed on storage tank 101, free terminal then forms the compacting end 140 of an arc, and the minimum point of each compacting end 140 is lower than the inside thickness of corresponding defining flange 13; And this plug 2 is provided with corresponding draw-in groove 20 at two elastic arms, 14 places of relative aforesaid sockets 1, when plug 2 inserts in the socket 1, each elastic arm 14 on the aforementioned shell 11 will be bestowed the chucking power of plug 2 one side direction relatively, to keep the stability of plug 2 in the grafting process, the compacting end 140 of two elastic arms 14 can fall into the draw-in groove 20 interior clamping location of plug 2 simultaneously, the stability after pegging graft with maintenance.

Above-mentioned USB socket 1 has following shortcoming: because elastic arm 14 ends must be lower than the width of defining flange 13, so the long elastic arm 14 of the arm of force must be arranged, end is extended to the position that is lower than defining flange 13 width, must keep simultaneously the elastic force of the long arm of force again, so that whole casing 11 all must use the preferable material of elasticity to make, for example use phosphor bronze (PHOSPHORBRONZE) sheet material integrated punching to go out shell 11 and elastic arm 14 at present, stronger elasticity and elastic force can be arranged so that have the elastic arm 14 of the long arm of force; But phosphor bronze sheet material is quite expensive, and causes whole universal serial bus connector to hold at high price.

Main purpose of the present utility model is to provide a kind of USB socket that can effectively reduce manufacturing cost.

The purpose of this utility model is to realize like this, a kind of USB socket, comprise a terminal base and a shell that is provided with terminal in order to the clad terminal seat, be characterized in: it also comprises an elastic strip body with elastic arm, and this terminal base is respectively equipped with a storage tank on the wall of correspondence; Two sidewalls of this elastic strip body are respectively equipped with a hangnail, and correspondence is provided with a guide rail on two sidewalls of this storage tank, and this elastic strip body is led in this storage tank of people by guide rail, and this hangnail thrusts the interior strong fix of guide rail of this storage tank.

Described this shell is to make with bronze, iron or any conductive lower cost materials, and this elastic strip body is to make with the preferable material of elasticity such as phosphor bronze.

Owing to adopted above-mentioned technical solution, the elastic arm of in the past USB socket and shell separated be provided with, elastic arm is not to be shaped on the shell, and shell can make with any conductive lower cost materials, so have the effect that required cost is made in effective reduction.

Below by most preferred embodiment and accompanying drawing the utility model USB socket is elaborated.

Fig. 1 is the three-dimensional exploded view of universal serial bus connector in the past;

Fig. 2 is the front view of USB socket among Fig. 1;

Fig. 3 is the cutaway view of Fig. 2;

Fig. 4 is the part three-dimensional exploded view of the utility model preferred embodiment;

Fig. 5 is the part enlarged drawing of the utility model preferred embodiment;

Fig. 6 is the assembled sectional view of the utility model preferred embodiment.

Shown in Fig. 4,5, the USB socket of the utility model preferred embodiment includes a terminal base 3, shell 4 and two elastic strip bodies 5.

This terminal base 3 is provided with terminal 30, is respectively equipped with a storage tank 31 on two side wall surfaces of this terminal base 3, and the upper and lower wall correspondence of this storage tank 31 is provided with a guide rail 32.

This shell 4 is to make with bronze material, iron material or the moulding of any conductive lower cost materials integrated punching, and to be coated on outside the terminal base 3, edge bends inwards into four defining flanges 41 around the front opening 40 of shell 4.

These elastic strip bodies 5, be to make with the preferable material of elasticity such as phosphor bronze, these elastic strip bodies 5 are roughly isometric and contour with the guide rail 32 of aforementioned this storage tank 31, these elastic strip bodies 5 can be inserted in the guide rail 32 of this storage tank 31, please cooperate consult shown in Figure 6, these inside punching presses in elastic strip body 5 lower ends form an abutting part 50, the then relative abutting part 50 reverse punching presses in upper end form an elastic arm 51, the free terminal of elastic arm 51 then forms the compacting end 510 of an arc, and the minimum point of each compacting end 510 is lower than the inside thickness of corresponding defining flange 41, two sidewalls at these elastic strip bodies 5 are respectively equipped with a hangnail 52, after making these elastic strip bodies 5 in importing this storage tank 31, can thrust by the hangnail 52 of its two sidewall in the guide rail 32 of this storage tank 31, firmly the location.

See also aforementioned figures, by above-mentioned structure, after making shell 4 outside being coated on terminal base 3, in regular turn these elastic strip bodies 5 are inserted in the storage tank 31 of this terminal base 3 again, the hangnail 52 of these elastic strip body 5 two sidewalls is thrust in the guide rail 32 of this storage tank 31, and firmly be positioned wherein.

The utility model USB socket is that two elastic strip bodies 5 are set in addition, and on these elastic strip bodies 5, stamp out an elastic arm 51, make elastic arm 51 no longer be shaped in (the USB socket was that integrated punching molds two elastic arms 14 on shell 11 in the past) on the shell 4, be respectively equipped with two hangnails 52 on these elastic strip bodies 5 and on storage tank 31 walls of terminal base 3, be provided with two guide rails 32 in the cooperation, and then reach the purpose of this utility model, make that having only these elastic strip bodies 5 to be still with the preferable material of elasticity such as phosphor bronze makes, can any conductive lower cost materials make as for 4 on shell, to reach the effect that required cost is made in effective reduction.
