Abstract
The invention relates to a high-current contact part with a composite structure. The high-current contact part comprises an insertion hole and an insertion pin, and is characterized in that one end of the insertion hole inserted with the insertion pin is divided into a multi-petal suspension arm structure by a plurality of structure grooves which are axially distributed and extended; a protection sleeve sleeves the multi-petal suspension arm structure; a central insertion pin is arranged in the multi-petal suspension arm structure; the insertion pin is inserted into the multi-petal suspension arm structure; an insertion pin hole formed along the axial direction of the insertion pin is formed in the end surface of the insertion pin at the insertion end; a ring of spring piece inserted with the central insertion pin is formed in the insertion pin hole.
Description
Technical field
The present invention relates to contact field, is a kind of big current contact of composite construction specifically.
Background technology
Contact is the important component part of electric connector, and the performance of contact directly has influence on the electric connector even quality of whole set equipment.Contact pin, the jack of general heavy-current electric connector adopt grooving sheet spring structure, contact point is few, contact resistance is large, consumption of calorie is many in the course of the work, electric connector has larger temperature rise, and the rising of connector internal temperature can affect contact resistance further, and simultaneous temperature raises the mechanical strength of meeting influence elastane contact, can vicious circle be formed like this, affect the laser propagation effect of big current.
Summary of the invention
The invention provides a kind of big current contact of composite construction, by the two contact of surfaces externally and internally, increase contact-making surface, reduce contact resistance, improve the reliability of contact.
Technical scheme of the present invention is: a kind of big current contact of composite construction, comprise 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 extends vertically, many lobes cantilever design overcoat has sheath, many lobes cantilever design Nei She center contact pin; Described contact pin plugs together in many lobes cantilever design, and mating side contact pin end face is provided with the pin holes along contact pin axis, the ring spring sheet that pin holes Nei Sheyu center contact pin plugs together.
Further, be provided with one between described many lobes cantilever design and sheath and bind round banding spring in 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.
Again further, described jack is elastic copper alloy jack.
By above technology, advantage of the present invention is: plug jack material is made up of elastic copper alloy, its front end fluting becomes the fixing many lobes cantilever design in one end, banding spring thereon, being closed up by many lobes cantilever design makes every lobe port inwardly shrink, plug together with contact pin and provide a normal pressure to contact pin surface afterwards, make to form electrical contact between contact pin jack; Further, at many lobes cantilever design Nei She center contact pin, with mate contact pin in conjunction with time can produce electrical contact with the reed in pin holes, the normal pressure of increasing is provided further; When contact pin, jack plug together, plugging together of guide cone pore structure and guide cone structure, is convenient to plug together.
The present invention can ensure the reliable contacts of contact pin and jack, and its contact point is many, effectively can increase ampacity, reduces the temperature rise of connector, is particularly suitable for the transmission of larger current.
Accompanying drawing explanation
Fig. 1 is jack structure schematic diagram;
Fig. 2 is contact pin structure schematic diagram;
Fig. 3 is that contact pin jack plugs together rear schematic diagram.
In figure: jack 1, sheath 2, spring 3, center contact pin 4, reed 5, contact pin 6.
Embodiment
Be described further below in conjunction with drawings and Examples.
Fig. 1 is jack structure schematic diagram.Mainly comprise jack 1, sheath 2, spring 3, center contact pin 4.Jack 1 is made up of elastic copper alloy, its front end fluting becomes the fixing many lobes cantilever beam structure in one end, 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 established in multiple tracks cannelure, many lobes cantilever beam structure overcoat has sheath 2, and 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, establishes 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 jack lobe more than 1 cantilever beam structure, being closed up by spring 3 makes many lobes cantilever beam structure port inwardly shrink, plug together with contact pin 6 and provide a normal pressure to contact pin surface afterwards, make to form electrical contact between contact pin, jack, the normal pressure of increasing is provided, many lobes cantilever beam structure Nei You center contact pin 4, with mate contact pin in conjunction with time can produce electrical contact with the reed 5 in pin holes.
