Fig. 1-3 is please referred to, the utility model embodiment provides a kind of electric connector comprising conducting sleeve 11, encapsulated
Shell 12 and resistance material ring 13.It should be noted that electric connector provided by the embodiment of the utility model can mainly be applied
But it is not limited to assist the stabilization established between component to male end electric connector on the electric connector of New-energy electric vehicle
Electrical connection.
Conducting sleeve 11, is made of an electrically conducting material, including for being electrically connected with contact pin plug division 111 and for lead
The wire connecting portion 112 of electric wire cable electrical connection, one end of plug division 111 are offered for mating to realize electricity with contact pin with contact pin
The other end of the spliced eye of connection, plug division 111 is electrically connected with wire connecting portion 112.It should be noted that conducting sleeve 11 can
Added using the good Cu alloy material machine of electric conductivity.Grafting is carried out by the plug division 111 of conducting sleeve 11 and contact pin,
Using conductive material electric conductivity by electric current from contact pin by 111 connection of plug division import wire connecting portion 112, then by with connect
The conductor cable that line portion 112 is electrically connected is transmitted and is gone out.
Encapsulated shell 12, is made of insulating material, including housing main body 121 and anticreep snap ring 122, housing main body 121
The grafting accepting hole for accommodating plug division 111 is offered in one side, and offers in its another side and is accommodated with grafting
Hole is connected to and is used to accommodate wire connecting portion 112 and is electrically connected to the wiring accepting hole of wire connecting portion 112, anticreep snap ring for conductor cable
122 extend inwardly to form from the aperture opening's edge of grafting accepting hole, are detached from grafting accepting hole to limit conducting sleeve 11.It needs herein
Illustrate, to avoid occurring between electric connector leaky, electric connector usually requires to be formed on its surface one layer of insulation
Shell, in this regard, traditional mode mostly use encapsulated Shooting Technique the outside of conducting sleeve 11 be wrapped to form an insulation crust with
Play the role of mutual electric insulation and obturage protection, to improve the resistance to ring such as the high temperature resistant of electric connector, low temperature resistant, fire-retardant
Border performance.Therefore, the encapsulated injection molding of thermosetting plastic can be used in encapsulated shell 12.By mold design, make encapsulated shell 12 1
It is body formed, housing main body 121 is formed to accommodate conducting sleeve 11, and it is de- to limit conducting sleeve 11 to form anticreep snap ring 122

The plug division of 14 limit sockets limits section 1112, and the outer diameter of plug division limit section 1112 is mutually fitted with 14 internal diameter of positioning ring
Match, the outer diameter of plug division inserting section 1111 is not less than the outer diameter of positioning ring 14.To be attached with resistance material ring 13, lead
The plug division 111 of electric sleeve 11 can be divided into two parts, and one of part, which is formed, can be used for limiting socket with positioning ring 14
Plug division limits section 1112, and the outer diameter of section 1112 and the outer diameter of plug division inserting section 1111 are limited by plug division
Gap formed for limit connection positioning ring 14 boss, specifically, plug division limit section 1112 outer diameter and positioning
14 internal diameter of ring is adapted, and the outer diameter of plug division inserting section 1111 can be greater than or equal to the outer diameter of positioning ring 14.
The setting that section 1112 is limited by positioning ring 14 and plug division, by the connection between resistance material ring 13 and conducting sleeve 11
Phenomena such as relationship becomes more to consolidate, and avoids the offset of resistance material ring 13 being likely to occur is possible can not effectively to stop absolutely
Edge material injects the problem of conducting sleeve 11.
Referring to Fig. 3, in the present embodiment, the opening direction of grafting accepting hole and the opening direction of wiring accepting hole are in vertical
Straight setting.Since the occupied space of electric connector of straight line transmitting electric current is larger, it is most during practice
