A kind of electric connector

Technical field

The utility model relates to a kind of highly reliable electric connector, belong to technical field of electric connectors.

Background technology

At present, common can transmit big electric current and simple in structure, fitting operation easily electric connector mainly by self-locking and two kinds of structures of band retaining device.The connector shell material of these two kinds of structures is rubber parts, and elasticity and contact pin, jack interference fit by rubber parts fix chipware, and therefore under severe environmental conditions, rubber parts is prone to aging phenomenon, and therefore this reliability of structure is not high.And the contact pin of these two kinds of structures and jack unprotect device, fail safe in use is not high.Self-locking in use contact with band retaining device connector the phenomenon that do not have self-locking to put in place is appearred in meeting, and also very high to requirement on machining accuracy for contacting.

Summary of the invention

The purpose of this utility model provides a kind of abominable occasion that can be used for, and simple and reliable for structure, fitting operation convenience, safety, good seal, electrical connection properties are reliable, stable, can transmit the electric connector of big electric current.

Technical solution of the present utility model: it is characterized in that forming by convex plug and cloudy socket, wherein convex plug comprises convex plug shell, contact pin assembly and cable joint, described convex plug shell is to be connected by insulated dowel with the contact pin inter-module, on the convex plug shell end face keyway is arranged, the key that two projectioies are arranged in the dowel hole has angle [alpha] between two keys; Cloudy socket is by insulated dowel cloudy jack housing and plugging hole component to be linked up,

Advantage of the present utility model: can be used for abominable occasion, simple and reliable for structure, fitting operation convenience, safety, good seal, electrical connection properties are reliable, stable, can transmit big electric current.

Embodiment

Contrast accompanying drawing 1-7, its structure is made up of convex plug and cloudy socket, wherein convex plug comprises convex plug shell 4, contact pin assembly 6 and cable joint 7, described convex plug shell 4 is to be connected by insulated dowel 5 with 6 of contact pin assemblies, on convex plug shell 4 end faces keyway 8 is arranged, have in convex plug shell 4 holes between 9, two keys of key of two projectioies certain angle [alpha] is arranged; Cloudy socket is by insulated dowel 5 cloudy jack housing 15 to be connected with plugging hole component 16.

Described cloudy jack housing 15 has two " P " shape draw-in grooves, and the angle between two of draw-in groove inlets 19 is identical with the angle between interior two the protruding keys 9 of convex plug shell aperture, has elasticity backstay 18 on cloudy jack housing one end face;

Described plugging hole component 16 has jack protection structure, mainly comprises stage clip card 12, compression spring cover 11, pressure spring head 10, press spring base 21 and interior stage clip 13, outer stage clip 14, also can have two in the porch of jack

Shape groove 25 is installed insulated dowel hole 17 on same straight line on this groove inlet and the jack.

Described contact pin assembly 6 has contact spring 2, and a certain size round metal pin 3 is housed on certain position, and the contact pin top end face is equipped with insulation protection lid 1.

Described cloudy jack housing one end face has elasticity backstay 18.

When convex plug and cloudy socket plug together, contact pin 6 makes stage clip card 12 skid off jack groove 24 by the compression spring cover in the jack 16 11, pressure spring head 10 makes the interior stage clip 13 that is contained on the

press spring base

21,14 compressions of outer stage clip, the cloudy jack housing 15 of convex plug shell 4 insertions this moment, rotate convex plug shell 4 after putting in place again, the key 9 of two projectioies snaps into respectively on the step of cloudy jack housing 15 " P " shape draw-in groove in this moment convex plug shell aperture, and the elasticity backstay 18 on the cloudy jack housing also bullet advanced in the keyway 8 of convex plug shell.This moment, two housings connected together reliably again.Convex plug shell 4 presses 0 shape sealing ring 20 on the cloudy jack housing, and the contact spring 2 on the contact pin also fully contacts with jack 16.This is that a kind of simple insurance blocks and location structure.

According to the service condition requirement, can have two in the porch of jack

Shape groove 25, when convex plug and cloudy socket plug together put in place after, the round metal pin 3 on this moment contact pin passes through

Shape groove inlet enters, and when rotation convex plug shell 4, the round metal pin 3 on the contact pin sticks into

In the shape groove, simultaneously the key 9 of two projectioies also snaps into respectively on the step of cloudy jack housing 15 " P " shape draw-in groove in the convex plug shell aperture, and the elasticity backstay 18 on the cloudy jack housing also bullet advanced in the keyway 8 of convex plug shell.This is that a kind of dual fail-safe is blocked and location structure.

Between two " P " shape draw-in groove inlets 19 certain angle [alpha] is arranged between the key 9 of two projectioies and on the cloudy jack housing in the convex plug shell aperture, can make the angle of different sizes, satisfy anti-error function between the connector according to instructions for use.

The contact pin top end face is equipped with insulation protection lid 1, and plugging hole component has jack protection structure, therefore in use has very high fail safe.

The contact pin assembly has contact spring 2, so electric connector has that contact resistance is little, contact is reliable, can transmit characteristics such as big electric current.

Contrast Fig. 8, Fig. 8-1, Fig. 9, Figure 10 and Figure 11, according to different electrical connection requirements, this structure also can be designed as cloudy plug and these two kinds of structures of positive socket, and cloudy plug is made up of cloudy plug body 22 and plugging hole component 16, and positive socket is made up of positive jack housing 23 and contact pin assembly 6.Thereby satisfy various electrical connection requirements, it is flexible and changeable that connector is used.
