Abstract

An electric connector comprises a sleeve and a contact spring contained in the sleeve, wherein the contact spring comprises a fixing ring fixed in the sleeve and a plurality of reeds extending out along one side of the fixing ring. One ends, far away from the fixing ring, of the reeds are mutually independent structures and are respectively abutted against the inner wall surface of the sleeve. The spring structure has more reliable elasticity and contact force.

Description

Electrical connector

[ technical field ] A method for producing a semiconductor device

The present invention relates to an electrical connector, and more particularly, to an electrical connector having a contact spring.

[ background of the invention ]

Chinese invention patent No. CN101969160A discloses a crown spring cage jack and a crown spring thereof, a crown spring cage jack, characterized in that: the jack comprises an inner sleeve, a crown spring penetrates through an inner hole of the inner sleeve, the crown spring comprises two end rings which are positioned at two ends and coaxially arranged, connecting wire spring strips are integrally connected between the two end rings, and the extending direction of each connecting wire spring strip is intersected with the axial space of the two end rings and deflects along the same trend relative to the axial space of the end rings.

The utility model provides a hat spring of hat spring cage jack which characterized in that: the crown spring comprises two end rings which are coaxially arranged at two ends, connecting wire spring strips are integrally connected between the two end rings, and the extending direction of each connecting wire spring strip is intersected with the axial space of the two end rings and deflects along the same trend relative to the axial space of the end rings. The elastic force of the crown spring contacting the inner wall and the contact force of the crown spring contacting the contact pin are insufficient.

It is therefore desirable to design an improved electrical connector that overcomes the above-mentioned deficiencies.

[ summary of the invention ]

The technical problem to be solved by the invention is as follows: an electrical connector is provided having better transmission of force.

In order to solve the above problems, the present invention can adopt the following technical scheme:

an electric connector comprises a sleeve and a contact spring accommodated in the sleeve, wherein the contact spring comprises a fixing ring fixed in the sleeve and a plurality of reeds extending out along one side of the fixing ring; one ends, far away from the fixing ring, of the reeds are mutually independent structures and are respectively abutted against the inner wall surface of the sleeve.

Compared with the prior art, the reed has more reliable elasticity and contact force.

Electrical connector 100 sleeve 1

Inner wall surface 102 of containing chamber 101

Contact spring 2 fixing ring 21

Supporting part 220 of reed 22

Contact 221 butt-joint terminal 200

The following detailed description will further illustrate the invention in conjunction with the above-described figures.

[ detailed description ] embodiments

Referring to fig. 1 to 2, the present invention discloses an electrical connector 100 for transmitting large current, wherein the electrical connector 100 includes a sleeve 10 and a contact spring 20 accommodated in the sleeve 10. The sleeve 10 is made of insulating plastic material, and the contact spring 20 is made of metal material.

Referring to fig. 2, the sleeve 10 has a cylindrical shape and is provided with a receiving cavity 101 for receiving the contact spring 20, the receiving cavity 101 is formed to penetrate forward to form one end of the sleeve 10 as an opening, and the other end of the sleeve 10 as a closed shape.

The contact spring 20 includes a fixing ring 21 fixed in the sleeve 10 and a plurality of spring leaves 22 extending along one side of the fixing ring 21. The ends of the spring pieces 22 away from the fixing ring 21 are independent structures and are respectively abutted against the inner wall surface 102 of the sleeve 10 (see fig. 4). The spring pieces 22 are gradually bent inward from the two ends to the middle to form a contracted contact portion 221 located in the middle, and the contact portion 221 is electrically connected to the butt terminal 200 to stably transmit a large current. As shown in fig. 4, the mating terminal 200 is accommodated in the contact spring 20, and the contact portion 221 is uniformly attached to the outer peripheral surface of the mating terminal.

The end of the spring leaf 22 is bent reversely outward to form a support part 220, and the support part 220 elastically abuts against the inner wall surface 102 of the sleeve 10 to provide reliable elastic force for contacting the spring 20. The support portion 102 has a contact surface abutting against the inner wall surface 102 of the sleeve, and the contact surface is an arc surface, so that smooth hand feeling is provided in the plugging process. In this embodiment, the spring 22 is bent outward and reversely to form a U-shaped support portion 220.

Referring to fig. 1 and 4, the fixing ring 21 is attached to the inner wall surface 102 of the accommodating cavity 101 and located at the opening of the accommodating cavity 101. The spring piece 22 extends into the housing cavity 101, an elastic deformation space is formed between the spring piece 22 and the inner wall surface 102, the support portion 220 abuts against the inner wall surface 102 near the closed end of the housing cavity 101, and an elastic deformation space is formed between the support portion 220 and the mating terminal 200.

The above-described embodiments are presently preferred, but not necessarily all, embodiments of the invention. Any equivalent variations of the technical solutions of the present invention that a person of ordinary skill in the art would take upon reading the present specification are covered by the claims of the present invention.
