Abstract
The utility model relates to a composite construction's heavy current contact, including jack and contact pin, its characterized in that: inserting the jack one end multichannel on it that closes the contact pin and distributing, cut apart to become inner fixed many lamellas cantilever structure along axially extended structure groove around the axial, many lamellas cantilever structure overcoat has the sheath, establishes central contact pin in many lamellas cantilever structure, in the contact pin is inserted and is fitted many lamellas cantilever structure, insert close end contact pin terminal surface be equipped with along insert needle shaft to the contact pin hole, the round reed that closes is inserted with central contact pin to downthehole the establishing of contact pin.
Description
Technical field
This utility model relates to contact field, the big current contact of a kind of composite construction.
Background technology
Contact is the important component part of electric connector, and the performance of contact directly influences the electric connector even quality of whole set equipment.The general contact pin of heavy-current electric connector, jack use grooving sheet spring structure, contact point is few, contact resistance is big, consumption of calorie is many in the course of the work, electric connector has bigger temperature rise, and adapter internal temperature rising can affect contact resistance further, and temperature rising simultaneously can affect the mechanical strength of resilient contact, so can form vicious cycle, affect the laser propagation effect of big electric current.
Summary of the invention
This utility model provides the big current contact of a kind of composite construction, by the double contact of surfaces externally and internally, increases contact surface, reduces contact resistance, improve the reliability of contact.
The technical solution of the utility model is: the big current contact of a kind of composite construction, including jack and contact pin, described jack one end plugging together contact pin multiple tracks on it is divided into inner fixing many lobes cantilever design around axial distribution, the structure grooves that axially extends, sheath, many lobes cantilever design Nei She center contact pin it is cased with outside many lobes cantilever design；Described contact pin plugs together in many lobes cantilever design, and mating side contact pin end face is provided with along the axial pin holes of contact pin, the ring spring sheet that pin holes Nei Sheyu center contact pin plugs together.
Further, it is provided with one between described many lobes cantilever design and sheath to bind round in the banding spring of many lobes cantilever design excircle.
Further, described banding spring is arranged in the multiple tracks cannelure on many lobes cantilever design excircle.
Further, the collar extension of described sheath or the collar extension of many lobes cantilever design are guide cone pore structure, and described contact pin mating side collar extension is the guide cone structure of corresponding guide cone pore structure.
Yet further, described jack is elastic copper alloy jack.
By above technology, the utility model has the advantages that: plug jack material is made up of elastic copper alloy, its front end fluting becomes many lobes cantilever design that one end is fixing, banding spring thereon, being closed up by many lobes cantilever design makes every lobe port to contract, there is provided a normal pressure to contact pin surface after plugging together with contact pin, make to be formed between contact pin jack electrical contact；Further, at many lobes cantilever design Nei She center contact pin, electrical contact can be produced with the reed in pin holes when the contact pin of coupling is combined, it is further provided the normal pressure of increasing；When contact pin, jack plug together, plugging together of guide cone pore structure and guide cone structure, it is simple to plug together.
This utility model can guarantee that the reliable contacts of contact pin and jack, and its contact point is many, can be effectively increased current-carrying capacity, reduces the temperature rise of adapter, is particularly suitable for the transmission of larger current.

Detailed description of the invention
It is described further below in conjunction with drawings and Examples.
Fig. 1 is jack structure schematic diagram.Mainly include jack 1, sheath 2, spring 3, center contact pin 4.Jack 1 is made up of elastic copper alloy, its front end fluting becomes many lobes cantilever beam structure that one end is fixing, many lobes cantilever beam structure Nei She center contact pin 4, many lobes cantilever beam structure outer wall is provided with multiple tracks cannelure, spring 5 banding many lobes cantilever beam structure is set in multiple tracks cannelure, being cased with sheath 2 outside many lobes cantilever beam structure, the collar extension of sheath 2 is guide cone pore structure.
Fig. 2 is contact pin structure schematic diagram.The mating side of contact pin 6 is provided with axial pin holes, sets a ring spring sheet 5 in pin holes, and the mating side collar extension of contact pin is guide cone structure.
Fig. 3 is that contact pin jack plugs together rear schematic diagram.The outer banding spring of the jack cantilever beam structure of lobe more than 1, being closed up by spring 3 makes many lobes cantilever beam structure port to contract, a normal pressure is provided to contact pin surface after plugging together with contact pin 6, make to be formed between contact pin, jack electrical contact, the normal pressure strengthened is provided, many lobes cantilever beam structure Nei You center contact pin 4, can produce electrical contact with the reed 5 in pin holes when the contact pin of coupling is combined.
Claims (5)
