Abstract

The utility model discloses a kind of silk ring jack contact, this thread ring jack contact is different from traditional contact piece structure, contact of the present utility model is to turn to multiple continuous rectangles first by a copper wire, then multiple rectangle copper wires closely overlap, form the spring-like wrapping wire of rectangular opening, finally the front and rear rectangular port of the spring-like wrapping wire of the rectangular opening is connected to forming annular contact part, the contact is simple many compared to traditional grid contact, and then processing technology greatly optimizes, performance and yield are improved.The utility model contact have the advantages that contact engaging and separating force is soft, temperature rise is low, antivibration power is strong, long lifespan, be adapted to high current connection, no specification limitation, specification can arbitrarily be adjusted according to customer demand.

Description

A kind of silk ring jack contact

Technical field

Technical field of electric connectors is the utility model is related to, particularly relates to a kind of silk ring jack contact.

Background technology

Its full name of hyperboloid wire spring socket is one sheet hyperboloid wire spring socket, is electric connector (i.e. connector) product On a kind of highly reliable plugging hole component for using.By more elasticity are gold-plated or silver plated metals silk is by the straight of one sheet hyperboloid in hole Bus arranges, and is had angle with inner sleeve straight edge line shape.When contact pin inserts coil spring hole, coil spring silk all occurs radial and axial Elastic deformation, contact pin contact simultaneously with more in coil spring hole independent coil spring silks, form multiple independent current paths.Even if Indivedual coil spring silks fracture in jack, coil spring hole remains to form effective current path.When contact pin inserts jack, these elasticity Tightly envelope around contact pin, forms line contact to wire respectively, and a pair of pin holes make equivalent to several to common pin, hole parallel connection With drastically increasing contact reliability.Therefore it is the advantages of its protrusion:Contact resistance is low and stablize, contact engaging and separating force is small, contact It is long and in strength vibrates shock environment to wear low, connect-disconnect life, can keep the high reliability made electrical contact with.

Because the continuous renewal of technology is, it is necessary to which new contact substitutes traditional grid copper cash, to obtain more preferable effect Fruit.

The content of the invention

For deficiency of the prior art, the technical problems to be solved in the utility model is the provision of a kind of silk ring jack Contact.

In order to solve the above technical problems, the utility model is realized by following scheme：A kind of silk ring jack contact, should Silk ring jack contact includes metal copper sheathing, contact, metal backup shoe；

The both ends of the metal copper sheathing are two cylindrical tube shapes respectively, its small one and large one, big cylindrical drum is longer, and its end is set Trough with straight angle circle is equipped with, it is provided with flange collar with roundlet column casing joint, and a circle is provided with the big cylindrical drum outer wall of flange collar Groove；

The contact is to turn to multiple continuous rectangles first by a copper wire, and then multiple rectangle copper wires are closely folded Close, form the spring-like wrapping wire of rectangular opening, finally the front and rear rectangular port of the spring-like wrapping wire of the rectangular opening connects to forming circle Shape contact, the annular contact part are socketed on the big cylindrical drum oral area, then covered with metal backup shoe.

Further, through hole between the big cylindrical drum of the metal copper sheathing and roundlet column casing.

Further, the metal backup shoe is in flattened cylindrical shape, middle through-hole, and through hole is placed on the trough with straight angle circle.

Relative to prior art, the beneficial effects of the utility model are：The utility model silk ring jack contact and tradition Contact piece structure it is different, contact of the present utility model is to turn to multiple continuous rectangles first by a copper wire, then Multiple rectangle copper wires closely overlap, and form the spring-like wrapping wire of rectangular opening, finally by before and after the spring-like wrapping wire of the rectangular opening Rectangular port connects to forming annular contact part, and the contact is simple many compared to traditional grid contact, and then processes Technique greatly optimizes, and improves performance and yield.The utility model contact has that contact engaging and separating force is soft, temperature rise is low, anti-vibration Power is strong, long lifespan, the advantages that, be adapted to high current connection, no specification limitation, specification can arbitrarily be adjusted according to customer demand.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model Define.

Accompanying drawing 1-6, a kind of silk ring jack contact of the present utility model are refer to, this thread ring jack contact includes metal Copper sheathing 1, contact 2, metal backup shoe 3；

The both ends of the metal copper sheathing 1 are two cylindrical tube shapes respectively, its small one and large one, big cylindrical drum 101 is longer, its end Portion is provided with trough with straight angle circle, and it is provided with flange collar 103 with the joint of roundlet column casing 104, close to the big cylindrical drum outer wall of flange collar 103 Place is provided with a circle groove 102；

The contact 2 is to turn to multiple continuous rectangles first by a copper wire, and then multiple rectangle copper wires are close Overlapping, forms the spring-like wrapping wire of rectangular opening, finally the front and rear rectangular port of the spring-like wrapping wire of the rectangular opening connects to being formed Annular contact part, the annular contact part are socketed on the oral area of big cylindrical drum 101, then covered with metal backup shoe 3.

Through hole between the big cylindrical drum 101 and roundlet column casing 104 of the metal copper sheathing 1.

The metal backup shoe 3 is in flattened cylindrical shape, middle through-hole, and through hole is placed on the trough with straight angle circle.

The utility model silk ring jack contact is different from traditional contact piece structure, contact of the present utility model be by A piece copper wire turns to multiple continuous rectangles first, and then multiple rectangle copper wires closely overlap, and form the spring-like of rectangular opening Wrapping wire, finally the front and rear rectangular port of the spring-like wrapping wire of the rectangular opening is connected to forming annular contact part, the contact is compared It is simple many in traditional grid contact, and then processing technology greatly optimizes, and improves performance and yield.This practicality is new Type contact have the advantages that contact engaging and separating force is soft, temperature rise is low, antivibration power is strong, long lifespan, be adapted to high current connection, no specification Limitation, can arbitrarily adjust specification according to customer demand.
