Abstract
It the utility model discloses a kind of plug-type connection structure for high-voltage electric connector, solves existing push-pull structure circlip postposition installation, and needs to be coupled with pressure ring, installation dimension is longer, and housing outer diameter is larger, the higher problem of production cost.The plug-type connection structure of the utility model includes shell, coupling nut, circlip and spring.Compared with existing postposition push-pull structure, the housing outer diameter size of the utility model is smaller, high production efficiency and save the cost.Circlip is directly fixedly connected with nut and spring with shell cooperation, reduces number of parts, shortens installation dimension, and reduce cost of parts.
Description
Technical field
The utility model relates to high-tension connector technical fields, specifically provide a kind of push-and-pull for high-voltage electric connector
Formula connection structure.
Background technique
At present in electric automobile high-voltage electric connector field, there are different demands for high current connector docking mode,
Push-pull structure as a kind of common structure for, strict control is needed for installation dimension and production cost.Existing push-and-pull
Formula structure circlip postposition installation, and need be coupled with pressure ring, installation dimension is longer, and housing outer diameter is larger, production cost compared with
It is high.
Utility model content
In order to solve the above-mentioned technical problem, it is simple to provide a kind of preposition installation of circlip, structure for the utility model, uses part
The low plug-type connection structure for high-voltage electric connector of negligible amounts, production cost.
To achieve the goals above, the utility model adopts the following technical solution: a kind of pushing away for high-voltage electric connector
Pull-type connection structure, the plug-type connection structure include shell, coupling nut, circlip and spring, and coupling nut inner circumferential is equipped with convex
Key, shell periphery are equipped with key mapping slot, and convex key is placed in key mapping slot and can be axially moveable in key mapping slot, and the spring pocket is mounted in
Shell periphery, and in compressive state be placed in coupling nut inner circumferential first annular boss and shell periphery the second annular convex platform it
Between in the cavity that is formed, be equipped with jump-ring slot in the shell periphery of key mapping front of the slot, circlip, coupling nut be installed in jump-ring slot
Compressed spring, and realized by the reciprocating motion of spring and moved axially in reciprocal fashion in shell periphery.
Further, the key mapping slot is U-shaped structure, and jump-ring slot is annular, and the radial depth and circlip of key mapping slot
The radial depth of slot is equal.
Further, the spring is made of stainless steel wire material.
Compared with prior art, the utility model has the following beneficial effects: compared with existing postposition push-pull structure,
The housing outer diameter size of the utility model is smaller, high production efficiency and save the cost.Circlip is directly fixedly connected with shell cooperation
Nut and spring, reduce number of parts, shorten installation dimension, and reduce cost of parts.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
- Fig. 4 referring to Fig.1, a kind of plug-type connection structure for high-voltage electric connector, the plug-type connection structure include
The side first annular boss 2-2 of shell 1, coupling nut 2, circlip 3 and spring 4,2 inner circumferential of coupling nut is equipped with convex key 2-1, shell
1 periphery of body is equipped with the key mapping slot 1-1 to match with convex key 2-1, and convex key 2-1 is placed in key mapping slot 1-1 and can be in key mapping slot 1-1
It is axially moveable, and rotate after can preventing coupling nut from assembling, the spring 4 is sleeved on 1 periphery of shell, and in compression shape
State is placed in the sky formed between the second annular convex platform 1-2 of 1 periphery first annular boss 2-2 and shell of 2 inner circumferential of coupling nut
In chamber, it is equipped with jump-ring slot 1-3 in 1 periphery of shell of the front end key mapping slot 1-1, circlip 3 is installed in jump-ring slot 1-3, connects spiral shell
2 compressed spring 4 of cap, and realized by the reciprocating motion of spring 4 and moved axially in reciprocal fashion in 1 periphery of shell.
The key mapping slot 1-1 is U-shaped structure, and jump-ring slot 1-3 is annular, and the radial depth and circlip of key mapping slot 1-1
The radial depth of slot 1-3 is equal.
The spring 4 is made of stainless steel wire material.
The push-pull structure of the utility model is used for high-voltage electric connector, and spring is first fitted in shell periphery by when use
On, then coupling nut is axially mounted on shell, then circlip is assemblied in shell snap ring groove with specific purpose tool, spring
In compressive state, with the sufficiently resilient service performance for guaranteeing the push-pull structure, since convex key can be in key mapping slot along axis
To activity, moved so axial push-and-pull coupling nut can make it do small range along shell peripheral, axial.
Specific case used herein is expounded the process and embodiment of the utility model, the above reality
The explanation for applying example is merely used to help understand the method and its core concept of the utility model；Meanwhile for the general of this field
Technical staff, based on the idea of the present invention, there will be changes in the specific implementation manner and application range.To sum up institute
It states, the content of the present specification should not be construed as a limitation of the present invention.
