Abstract

The utility model discloses a USB main body structure, which comprises a metal outer casing and a plug core. The plug core is positioned at the center part of the metal outer casing, four metal conductive contact wires are arranged on each surface of the plug core, and the contact wires on the both surface of the plug core are arranged in reverse direction. Through adopting the above structure, the USB plug can be inserted into the USB main body no matter in positive or negative direction without changing the prior USB plug structure. The trouble that the inserting direction is required to be changed when the inserting direction of the USB plug is wrong can be effectively avoided, and therefore the USB main body structure is convenient to be operated by users.

Description

A kind of two-sided USB precursor structure of inserting

Technical field

The utility model relates to a kind of USB precursor structure, especially a kind of two-sided USB precursor structure of inserting.

Background technology

Being seen in the market USB (universal serial bus) structure is made up of USB parent and USB plug.The USB parent is also referred to as USB socket, generally be installed on the computer body, and USB plug generally is installed on memory devices such as USB flash disk, MP3 or other the computer peripheral equipment.

The USB parent is made up of the metal shell and the lock pin of outside.Lock pin is positioned at that of metal shell is half side, and another of housing is half side to be cavity, is used for linking to each other with the lock pin of USB plug, only has four strip metals conduction to touch line on the lock pin of housing internal cavity direction.The purpose of doing like this is to prevent that the USB plug direction is anti-inserted, i.e. fool proof design.

Though present USB structure has the fool proof function, but when inserting USB plug, the user is very difficult disposable directly to be inserted into plug in the USB parent, direction not to the time, must oppositely just can be inserted in the socket plug, when particularly using the rearmounted USB socket of computer housing, owing to may not face USB socket, and the place, position of USB socket can only be felt, gropingly even if felt the USB socket position in the accurate position of positioning socket, may be because plug direction be not right, need plug is reverse, go to grope the position of USB socket once more, bring great inconvenience to use.

Summary of the invention

The utility model is made improvement at USB precursor structure in the market, and the concrete technical scheme that adopts is:

Improved USB parent is made of metal shell and lock pin, and the position of lock pin is positioned at the middle part of metal shell, and the two sides of lock pin is all touched line by four strip metals conductions and formed, and the line that touches on lock pin two sides puts in order oppositely.Adopt this structure, need not change the prior USB plug construction, just can USB plug can be inserted into the USB socket from both forward and reverse directions.Can avoid effectively the USB plug direction of insertion not to the time need change the trouble of direction of insertion, be very easy to user's use.

Accompanying drawing

Further specify the utility model below in conjunction with accompanying drawing.

Fig. 1 is a stereogram of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Embodiment

Fig. 1 and Fig. 2 are the utility model preferred embodiment.Fig. 1 is the three-dimensional view of the utility model embodiment.1 is metal shell, and 2 is lock pin, and 3 touch line for the metal on the lock pin.Pack into the center of housing 1 of lock pin 2 makes USB plug all can be inserted in the housing from left and right sides both direction, packs the back effect into as shown in Figure 2, and Fig. 2 is the vertical view of Fig. 1.Two faces all have metal to touch line 3 on the lock pin 2, it is opposite that putting in order of line touched on the two sides, one side put in order into power Vcc+, data-(data-), data+(data+) and earth connection (GND), another side touch line put in order for earth connection (GND), data+(data+), data-(data-) and power Vcc+.

The utility model can be applied on computer body, USB extended line and other the equipment that has the USB parent.

Claims

1. a two-sided USB interface precursor structure of inserting comprises metal shell (1) and lock pin (2); It is characterized in that lock pin (2) is gone up the two sides all has metal to touch line (3), described metal touches line and puts in order oppositely, and the position of lock pin (2) is positioned at the centre of metal shell (1).
