Description

Electric connector

Technical field

This utility model relates to a kind of electric connector, particularly relates to a kind of electric connector with inner metal shell and plastic shell.

Background technology

Existing USB plug adapter the most all includes inner metal shell and plastic shell, plastic shell usually relies on the elastic force of self to be attached on inner metal shell, this makes the attachment between inner metal shell and plastic shell fasten not, easily occurs loosening, and can not be accurately positioned between the two.

Thus, it is necessary to design a kind of new electric connector to solve above-mentioned technical problem.

Utility model content

The purpose of this utility model there are provided a kind of electric connector having and improving structural strength.

For realizing object defined above, this utility model adopts the following technical scheme that a kind of electric connector, it includes an insulating body, the some conducting terminals being contained in insulating body, the inner metal shell of coated insulation body and a plastic shell of collecting inner metal shell, described inner metal shell includes end face, bottom surface and connect the two sides of end face and bottom surface, described plastic shell includes roof, diapire and connect the two side of roof and diapire, at least one side opening is respectively offered in described two sides, each described side opening convex stretches out a buckling piece, at least one buckle slot is respectively offered on the inwall of described two side, described buckling piece is correspondingly embedded in buckle slot and makes inner metal shell and plastic shell keep fixing.

As further improvement of the utility model, described buckling piece has angle with the side shape at side opening rear, and described angle is less than 45 °.

As further improvement of the utility model, described inner metal shell rear end is provided with a riveted riveted sheet on cable.

As further improvement of the utility model, rear end, described two sides is protruding with for limiting the bending lug that plastic shell is moved rearwards by.

As further improvement of the utility model, described buckling piece is square.

As further improvement of the utility model, described buckle slot is square.

This utility model electric connector arranges buckling piece and lug on inner metal shell, the buckle slot of buckling piece embedding plastic shell sidewall inwall make inner metal shell and plastic shell combine closely, simple and convenient assembly is easily, conveniently, it is accurately positioned and is difficult to appearance between inner metal shell and plastic shell to loosen, improve the structural strength of electric connector.

Detailed description of the invention

Referring to Fig. 1, the electric connector 100 shown in 2, it includes an insulating body (not shown on figure), some conducting terminals (not shown on figure) of being contained in insulating body, the inner metal shell 3 of coated insulation body, cladding one plastic shell 4 of inner metal shell 4, cable 5, cladding connect the insulation fixed block 6 of inner metal shell 3 and cable 5, the metal front 7 of accommodating conducting terminal and connect the circuit board 8 of conducting terminal and cable 5.

Inner metal shell 3 includes end face 31, bottom surface 32 and connects the two sides 33 of end face 31 and bottom surface 32, and a side opening 331 is respectively offered in two sides 33, and each side opening 331 convex stretches out a buckling piece 332.

In the present embodiment, side opening 331 is square hole, and buckling piece 332 is square, and buckle slot 431 is square.

Buckling piece 332 has angle with side 33 shape at side opening 331 rear, and angle is less than 45 °, and in the present embodiment, this angle is 15 °, can also be 5 ° in other embodiments, 10 °, 30 degree etc..

Inner metal shell 3 rear end is provided with riveted sheet 34, and riveted is on cable 5, and reshaping insulation fixed block 6 is coated with inner metal shell 3 and cable 5, the outwardly bending lug 333 in rear end, inner metal shell 3 side 33.

After inner metal shell 3 assembles with plastic shell 4, buckling piece 332 limits plastic shell 4 and moves forward, and lug 333 limits plastic shell 4 and is moved rearwards by.

Plastic shell 4 includes roof 41, diapire 42 and connects the two side 43 of roof 41 and diapire 42, refer to shown in Fig. 3, a buckle slot 431 is respectively offered on the inwall of two side 43, lug 333 limits plastic shell 4 and is moved rearwards by, and buckling piece 332 is correspondingly embedded in buckle slot 431 and makes inner metal shell 3 and plastic shell 4 keep fixing and are accurately positioned.

In other embodiments, multiple side opening 331 is respectively offered in two sides 33, and each side opening 331 convex stretches out a buckling piece 332, and multiple buckling pieces 332 front and rear row cloth on side 33 becomes at least one row；Two side 43 inwall respectively offers multiple buckle slot 431, and multiple buckle slots 431 front and rear row cloth on sidewall 43 inwall becomes at least one row.

In certain embodiments, inner metal shell 3 is internal in electric connector 100 presented in shielding metal-back.

This utility model electric connector 100 arranges buckling piece 332 and lug 333 on inner metal shell 3, buckling piece 332 embeds in the buckle slot 431 of plastic shell 4 sidewall 43 inwall and inner metal shell 3 and plastic shell 4 is combined closely, and is accurately positioned and is difficult to occur loosening between inner metal shell 3 and plastic shell 4.

Although being example purpose, have been disclosed for preferred implementation of the present utility model, but those of ordinary skill in the art is it will be appreciated that in the case of without departing from by scope and spirit of the present utility model disclosed in appending claims, various improvement, to increase and replace be possible.
