The utility model discloses an one of the purpose adopts following technical scheme to realize: the utility model provides a compound plug connector of elasticity, includes hole cover and package spring, the hole cover includes grafting portion, offer on the grafting portion and supply contact pin male jack, one side of grafting portion is equipped with the elasticity opening, the package spring wraps up in the outside of grafting portion, and is equipped with the elastic bulge on the package spring, the elastic bulge inlays to be located the elasticity opening is and extend to in the jack.

Further, the elastic opening is in a linear structure and is parallel to the central axis of the jack.

Furthermore, a first limiting bulge and a second limiting bulge of an annular structure are respectively arranged at two ends of the insertion part, and the elastic opening extends to the first limiting bulge;

and the inner wall of the first limiting bulge and the central axis of the jack form an included angle smaller than 90 degrees.

Furthermore, the cross section of the elastic bulge is in an isosceles trapezoid structure;

and one side of the elastic bulge, which is back to the jack, is of a hollow structure.

Furthermore, one side of the elastic bulge facing the first limiting bulge is an inclined plane.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the contact area of contact pin (plug) and jack, elasticity limit structure (both package springs) has been increased, has remain the elasticity limit structure in the jack simultaneously, after the contact pin gets into the jack, can in time carry out the butt with elasticity limit structure to fixed contact pin, plug power is stable, and electric property is stable, and is safe in utilization.

The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following preferred embodiments are described in detail with reference to the accompanying drawings.

In the figure: 1. sleeving a hole; 2. wrapping a spring; 3. a plug-in part; 4. a jack; 5. an elastic bulge; 6. a first limit protrusion; 7. a second limit bulge; 8. and (4) elastic opening.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Combine fig. 1 to fig. 3 to show, a compound plug connector of elasticity, including hole cover 1 and package spring 2, hole cover 1 includes grafting portion 3, offers on the grafting portion 3 to supply contact pin male jack 4, and one side of grafting portion 3 is equipped with elasticity opening 8, and package spring 2 wraps up in the outside of grafting portion 3, and is equipped with elastic bulge 5 on the package spring 2, and elastic bulge 5 inlays and locates elasticity opening 8 and extend to in the jack 4, is used for conflicting the contact pin. The elastic opening 8 enables the inserting part 3 to have elastic expansion capacity, and the abutting contact pin can be automatically tightened.

The elastic opening 8 is of a linear structure and is parallel to the central axis of the jack 4, a first limiting bulge 6 and a second limiting bulge 7 of an annular structure are respectively arranged at two ends of the insertion part 3 to form a space for accommodating the wrap spring 2, two ends of the wrap spring 2 are fixed through end faces of the two bulges, and the elastic opening 8 extends to the first limiting bulge 6, so that the jack 4 keeps the elasticity of expansion;

in addition, the inner wall of the first limiting bulge 6 and the central axis of the jack 4 form an included angle smaller than 90 degrees, so that the included angle is open, the guiding function is achieved, and the insertion of a contact pin is facilitated.

The cross section of the elastic bulge 5 is of an isosceles trapezoid structure, so that the contact and friction between the elastic bulge 5 and the inner wall of the elastic opening 8 are reduced, the interference resistance is reduced when the contact pin is inserted, and the pre-tightening force between the contact pin and the elastic bulge is adjusted as completely as possible through the wrap spring 2; and one side of the elastic bulge 5 back to the jack 4 is of a hollow structure, so that the wrap spring 2 can be formed through punching, and the weight and the material are reduced.

Elastic bulge 5 is the inclined plane towards one side of first spacing arch 6, makes the contact pin when inserting, reduces the resistance of this side to the contact pin, also avoids the fish tail contact pin, and after the contact pin inserts completely, the contact pin is ejecting jack 4 with elastic bulge 5, and self is abundant with the inner wall contact of jack 4.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
