Abstract

The utility model provides an electric connector comprising an insulating body, a conductive terminal and a metal shell. The conductive terminal is installed on the insulating body. The metal shell covers the insulating body. An edge of the metal shell is integrally and reversely bended and extended with a spring piece used for contacting with an outer shell. The spring shell comprises a reflexed part, an elastic part and a contact part. The thickness of the material of the elastic part is smaller than the thickness of the material of the metal shell, thus the spring piece has more excellent elasticity, and the reliability and stability of the contact of the spring piece with the outer shell are raised so as to eliminate noises on the outer shell well. In addition, the spring piece is reversely bended backward on the metal shell to be formed in an integrated way, the structure is simple, thus the shaping of the metal shell is convenient, an assembly process is simplified, and the reduction of production cost is facilitated.

In view of this, with not enough, process studies for a long period of time this design people for defects, and cooperates the utilization of scientific principle, creates a kind of design scheme that can solve above-mentioned deficiency and defective.

[utility model content]

The main purpose of this creation is to provide a kind of electric connector, and this electric connector has the shell fragment of excellent spring and integral structure, and it can form stable the contact with exterior case, with the existing not good problem of electric connector earthing effect of effective solution.

For reaching the above-mentioned purpose of this creation, the utility model adopts following technical scheme:

A kind of electric connector, include insulating body, conducting terminal and metal shell, this conducting terminal is installed on the insulating body, this metal shell covers on the insulating body outward, this metal shell ora terminalis one inverse bending is extended with the shell fragment that contacts for exterior case, described this shell fragment includes invayination, elastic portion and contact site, and the material thickness of described elastic portion is less than the material thickness of metal shell.

As a kind of preferred version, described shell fragment is oppositely backward one bending formation on the front-end edge of metal shell interface.

As a kind of preferred version, described shell fragment is oppositely backward one bending formation on the front-end edge of the top board of metal shell.

As a kind of preferred version, described shell fragment is oppositely backward one bending formation on the front-end edge of the sidewall of metal shell.

As a kind of preferred version, described shell fragment is inserted oppositely forward one bending formation on the end edge in metal shell.

As a kind of preferred version, described electric connector is a kind of HDMI electric connector, and the metal shell on it includes top board, base plate and connects the side plate of top board and base plate.

Compared to prior art, the utility model beneficial effect is: utilize the elastic portion with metal shell to thin through punching press, so that the elastic portion material thickness is less than the material thickness of metal shell, thereby so that this shell fragment has better elasticity; This shell fragment extends integrally formed in metal shell ora terminalis inverse bending, simple in structure, so that metal casing forming is convenient, and has simplified the assembling process of product, avoided simultaneously existing electric connector to cause shell fragment to contact unsettled situation with casing because becoming flexible appears in the second metal shell.

Be clearer elaboration architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.

Have execution mode:

See also Fig. 3 to shown in Figure 6, it has shown the concrete structure of the preferred embodiment of the utility model, and this electric connector is the electric connector 2 of a kind of HDMI, and it includes insulating body 20, conducting terminal 30 and metal shell 40.

Wherein, this conducting terminal 30 is positioned on the insulating body 10, this metal shell 30 is coated on the insulating body 20, the concrete structure of this conducting terminal 20 and insulating body 10 is existing mature technology, be not described in detail at this concrete structure to conducting terminal 30 and insulating body 20, and the assembled relation between this insulating body 20, conducting terminal 20 and the metal shell 40 is not described in detail the assembled relation between insulating body 20, conducting terminal 30 and the metal shell 40 at this also for existing mature technology.

The left and right sides plate 43 that described metal shell 40 includes top board 41, base plate 42 and connects top board 41 and base plate 42, the interface 44 ora terminalis one inverse bendings of this metal shell 40 are extended with for the shell fragment 45 of eliminating exterior case 50 noises, (seeing also the 6th diagram), this shell fragment 45 includes elastic portion 452 that an invayination 451, extends obliquely by invayination 451 and the contact site 453 of elastic portion 452 rear ends, and these invayination 451 one are connected on top board 41 front-end edges of metal shell 40.Material thickness on the described elastic portion 452 thins through punching press, makes elastic portion 452 material thicknesses less than the material thickness of metal shell 40, thereby so that this shell fragment 45 has good elasticity.

In the present embodiment, these shell fragment 45 1 end one are connected on the front-end edge of interface 44 of metal shell 40, but certainly this shell fragment 45 also one be connected on the end edge 46 of metal shell 40, to be limited, the other end is not free end.In addition, this shell fragment 45 also can extend from the ora terminalis bending of side plate 43 according to the position of exterior case, and this also is fine.

The using method that present embodiment is described in detail in detail is as follows:

During use, the fixing feet 47 on the electric connector is inserted in the external circuit board (not shown), and be welded and fixed with the external circuit board, so that electric connector integral body is fixed on the circuit board.Shell fragment 45 on it with based on parallel exterior case 50 contacts of metal shell 40, see also shown in the 6th figure, elastic portion 452 compressive deformations of this shell fragment 45, so that the contact site 453 on the shell fragment 45 contacts on the exterior case 50, this shell fragment 45 keeps keeping good contacting with casing 50, to reach the effect of eliminating noise on the casing 50.

Be with, in present embodiment, demonstration be that material thickness with the elastic portion 452 of shell fragment 45 thins through punching press, but sometimes in design, we can also all thin the material thickness of whole shell fragment 45 parts through punching press, this equally also can reach the enforcement effect of this creation.

Design focal point of the present utility model is: by the shell fragment design is formed by connecting by an invayination, a junction and an elastic portion, the material thickness of its elastic portion is thinner with respect to the material thickness of metal shell, utilization thins this elastic portion thickness, so that this shell fragment has better elasticity, the reliability and stability that this shell fragment contacts with exterior case further improve.

This creation for embodiment and accompanying drawing, only be illustrated for this creation of opposing, be to make and be familiar with purpose and the effect that this operator can understand this creation strictly according to the facts, but not to this creation any limitation in addition, this creation also still can have other change mode, so all persons that is familiar with the technique can understand purpose and the effect of this creation strictly according to the facts, to carry out other pattern under this case creation spirit and implement not breaking away from, the equivalence that all should be considered as this case claim is implemented.
