The utility model is achieved through the following technical solutions.
The utility model relates to a kind of shielding contact structures of electric connector, comprise connector shell, insulating base, insulation claw, O RunddichtringO and cable shielding mesh, described insulating base is fixedly installed in connector shell inside, described insulating base is provided with installing hole, described insulation claw comprises claw body and at least one pawl head, described claw body is provided with annular groove, the tail end of described pawl head is provided with elasticity location hook, described O RunddichtringO is installed on annular groove, described cable shielding mesh to be arranged between connector shell and O RunddichtringO and with connector shell close contact, described elasticity location hook coordinates fixing with the installing hole on insulating base.
As one preferred embodiment, the number of the pawl head of described insulation claw is 4.
As another preferred embodiment, the pawl head of described insulation claw is evenly distributed on the surface perimeter of insulation claw.
As another preferred embodiment, described cable shielding mesh is evenly arranged on outside O RunddichtringO circumference.
As another preferred embodiment, described insulation claw passes through compression molding.
As another preferred embodiment, the material of described insulation claw is nylon PA6.
[beneficial effect]
The technical scheme that the utility model proposes has following beneficial effect:
(1) the utility model utilizes the insulation claw with special construction fixed by cable and prevent it from rotating, simultaneously by arranging cable shielding mesh between connector shell and O RunddichtringO, when without the need to increasing other auxiliary components or operational sequence, utilize the elastic shrinkage of O RunddichtringO, make cable shielding mesh and connector shell close contact, therefore there is reliable shielding properties.
(2) the shielding contact structures that the utility model provides are assembled simple, the convenient manufacturing.

In figure, 1-connector shell; 2-insulating base; 3-insulate claw; 4-O RunddichtringO; 5-cable shielding mesh; 31-pawl head; 32-elasticity location hook.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, clear, complete description is carried out to embodiment of the present utility model, obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, neither to restriction of the present utility model.Based on embodiment of the present utility model, those of ordinary skill in the art, not paying the every other embodiment obtained under creative work prerequisite, belong to protection range of the present utility model.
Embodiment
The schematic diagram of the shielding contact structures of the electric connector that Fig. 1 provides for the utility model embodiment, the structural representation of the insulation claw 3 in the shielding contact structures of the electric connector that Fig. 2 provides for embodiment of the present utility model.As depicted in figs. 1 and 2, connector shell 1, insulating base 2, insulation claw 3, O RunddichtringO 4 and cable shielding mesh 5 is comprised.
It is inner that insulating base 2 is fixedly installed in connector shell 1, and insulating base 2 is provided with installing hole,
Insulation claw 3 comprises claw body and four pawl heads 31, four pawl heads 31 are fixedly connected with in claw body, four pawl heads 31 of insulation claw 3 are evenly distributed on the surface perimeter of insulation claw 3, in addition, the claw body of insulation claw 3 is provided with annular groove, the tail end of the pawl head 31 of insulation claw 3 is provided with elasticity location hook 32, and elasticity location hook 32 coordinates fixing with the installing hole on insulating base 2, O RunddichtringO 4 is installed in annular groove.Need to illustrate, the O RunddichtringO 4 in the present embodiment meets the national standard of O RunddichtringO.
Cable shielding mesh 5 to be arranged between connector shell 1 and O RunddichtringO 4 and with connector shell 1 close contact, particularly, cable shielding mesh 5 is evenly arranged on outside O RunddichtringO 4 circumference, need to illustrate, utilize the elastic shrinkage performance of O type circle enough to make cable shielding mesh 5 and connector shell 1 close contact.
In the present embodiment, insulation claw 3 is by compression molding, and in addition, the material of the claw 3 that insulate in the present embodiment is nylon PA6.
The following describes the assemble method of the present embodiment.
When assembling comprises the connector of the shielding contact structures provided in the present embodiment, first cable is penetrated in insulation claw 3, then four elasticity location hooks 32 of insulation claw 3 are pulled open a little, it is allowed to be stuck in the installing hole of insulating base 2 correspondence position, can prevent cable from rotating after insulating base 2 is fixing like this, O RunddichtringO 4 is loaded in the annular groove of claw, again the cable shielding mesh 5 handled well is evenly distributed on outside O RunddichtringO 4 circumference, during overall loading connector shell 1, utilize elasticity and the shrinkage of O RunddichtringO 4, make cable shielding mesh 5 and connector shell 1 close contact, reach shield effectiveness well.
