Abstract

The utility model provides a USB male connector. The USB male connector mainly comprises a metal housing, an insulating body base, a two-sided contact conduction type printed circuit board and an insulating body cover. The lower surface of the insulating body base is provided with four positioning columns, four positioning holes are formed in the two-sided contact conduction type printed circuit board, the upper surface of the insulating body cover is provided with four positioning grooves at positions corresponding to the positions of the positioning columns, and the four positioning columns on the lower surface of the insulating body base pass through the four positioning holes of the two-sided contact conduction type printed circuit board and in interference fixation with the four positioning grooves of the upper surface of the insulating body cover. The metal housing is a rectangular hollow housing, and the outer peripheral surface of the insulating body base and the outer peripheral surface of the insulating body cover are covered by the metal housing. According to the USB male connector of the utility model, a printed circuit board front surface and back surface wiring method is adopted, so the advantage of two-sided contact conduction can be realized when the USB male connector and a USB female socket are matched with each other, the front surface and the back surface of the USB male connector both can be inserted into the USB female socket, so that a more favorable experience is provided for users.

Description

A kind of USB Male head connector

Technical field

The utility model relates to the USB connector field, relates in particular to a kind of USB Male head connector of double contact conducting.

Background technology

USB (USB, Universal. be the most widely used a kind of coffret in the present personal computer peripheral device product Serial Bus), be to advocate initiation by Intel and Microsoft at first, up to the present experienced the evolution of four versions such as USB1.0, USB1.1, USB2.0, USB3.0.USB1.0,1.1,2.0,3.0 versions are supported respectively following four kinds of transmission rates: (1) low-speed mode transmission rate is 1.5Mbps; (2) mode transfer speed is 12Mbps at full speed; (3) the fast mode transmission rate is 480Mbps; (4) transmission rate reaches 5Gbps.

The USB Male head connector that occurs on the market at present all is based on the one direction inserted mode of USB association criterion, when this type of USB Male head connector and USB female seat interworking, can only the one direction insertion, thereby can make troubles to the user.

Summary of the invention

The purpose of this utility model is to provide a kind of USB Male head connector, can the double contact conducting when this USB Male head connector and USB female seat interworking, positive and negatively all can use.

The purpose of this utility model is achieved through the following technical solutions.

A kind of USB Male head connector mainly comprises metal shell, insulating body pedestal, double contact conducting pcb board and insulating body lid;

The lower surface of described insulating body pedestal is provided with four reference columns, is provided with four location holes at double contact conducting pcb board; The corresponding reference column of the upper surface position of insulating body lid is provided with four location notchs, four reference columns on the insulating body pedestal lower surface pass four location holes of double contact conducting pcb board, and fix with four location notch interference of the upper surface of insulating body lid, described metal shell is the rectangular hollow housing, and it is coated on the outer peripheral edges face of described insulating body pedestal and insulating body lid.

Preferably, the upper surface of described insulating body pedestal is provided with two stopper slots, and the lower surface of insulating body lid is provided with draw-in groove, and the upper and lower surface of described metal shell is respectively equipped with two positive stop spring plates, connects and fixes with described stopper slot and draw-in groove.

Preferably, described double contact conducting pcb board is thin printed circuit board, and the front end of its upper and lower surface is laid with respectively two or more golden fingers, and the upper surface golden finger is electrically connected respectively golden finger on the lower surface.

Preferably, the front end golden finger of described double contact conducting pcb board upper and lower surface is as four take Copper Foil conduction material forming and its quantity.

The utility model compared with prior art, beneficial effect is: the utility model USB Male head connector, adopt PCB circuit board positive and negative cabling mode, so that can the double contact conducting when this USB Male head connector and USB female seat interworking, positive and negatively all can use, for the user provides better experience.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

See also shown in Fig. 1,2,3, the utility model USB Male head connector mainly comprises metal shell 1, insulating body pedestal 2, double contact conducting pcb board 3 and insulating body lid 4.

Insulating body pedestal 2 and insulating body lid 4 are to be made by insulating material such as plastic cement or resins, the upper surface of insulating body pedestal 2 is provided with two stopper slots 21, its lower surface is provided with four reference columns 22, and corresponding reference column 22 positions are provided with four location holes 31 at double contact conducting pcb board 3; The corresponding reference column of upper surface 22 positions of insulating body lid 4 are provided with four location notchs 41, and its lower surface is provided with draw-in groove 42; Four reference columns 22 on insulating body pedestal 2 lower surfaces pass four location holes 31 of double contact conducting pcb board 3, and fix with four location notch 41 interference of the upper surface of insulating body lid 4;

Upper and lower surface at metal shell 1 is respectively equipped with two positive stop spring plates 11, outside the double contact conducting pcb board 3 that metal shell 1 cover is fixed in the above, and the draw-in groove 42 that covers 4 lower surfaces with two stopper slots 21 and the insulating body of the upper surface of insulating body pedestal 2 respectively connects and fixes.

Double contact conducting pcb board 3 is thin printed circuit board, its width is substantially equal to the width of insulating body pedestal 2, but so double contact conducting pcb board 3 cross-under insulating body pedestals 2, the front end of the upper surface of double contact conducting pcb board 3 is laid with two or more golden fingers, these golden fingers be take Copper Foil conduction material forming on upper surface and its quantity as four; Similarly, the front end of the lower surface of double contact conducting pcb board 3 is laid with two or more golden fingers, these golden fingers be take Copper Foil conduction material forming on lower surface and its quantity as four; And, be noted that especially four golden fingers on the upper surface are electrically connected respectively four golden fingers on the lower surface.So that the signal that transmits during the positive and negative insertion of USB male USB female seat is identical.

In the utility model, metal shell 1 is the rectangular hollow housing haply, and the outer peripheral edges face of its coated insulation main base 2 and insulating body lid 4 prevents electromagnetic interference so that the metallic shield effect to be provided, and the inner double contact conducting pcb board 3 of protection.
