Abstract

A high-power electric connector with zero plugging force comprises a plug and a socket, wherein the plug comprises inserting pieces, spring clamps and a base, the inserting pieces are fixedly arranged in the base, and the spring clamps are longitudinally and movably fixed on two end faces of the base and are symmetrically arranged; the socket comprises a pressing plate, a base and a reed, wherein the reed is Y-shaped, the base is provided with holes for mounting the pressing plate and the reed, the holes for fixing the pressing plate are symmetrically arranged at the upper end of the reed hole, the reed and the inserting sheet are correspondingly arranged and then fixed in the corresponding hole of the base, and meanwhile, the pressing plate is also fixed in the corresponding hole of the base. During butt joint, external force presses the two pressing plates and the spring clamps which are symmetrically arranged on the socket, and the inserting pieces of the plug are inserted into the reed of the socket to realize corresponding electrical connection. The utility model discloses there is not to insert between the contact member and closes power and separating force during butt joint, connects reliably, the manufacturability is good.

Description

ZIF large power, electrically connector

Technical field

The utility model belongs to technical field of electric connectors.

Background technology

The power-type electric connector requires by bigger electric current, so the size of contact is bigger; For obtaining less contact resistance and reduce caloric value, the separating force of power-type contact is more much bigger than the separating force of conventional non-power type contact, so plug difficulty comparatively in the use.And conventional contact piece structure all is that elastic wall is out of shape in advance, and in the use, elastic wall is pressed in certain deformation on the surface of another contact, and such contact is subjected to influencing elastic wall and can losing elastic force gradually of connect-disconnect life, and influences contact reliability.

Summary of the invention

The purpose of this utility model provides a kind of ZIF large power, electrically connector, solves that conventional power-type connector contact engaging and separating force is big, the life-span is low, the defective of contact reliability difference.

Zero plug power large power, electrically connector described in the utility model, be made up of plug and socket, described plug comprises inserted sheet 1, spring clip 3, pedestal 5, and inserted sheet 1 is arranged and is fixed in the pedestal 5, spring clip 3 longitudinally-movings are fixed on the both ends of the surface of pedestal 5, are symmetrical expression and arrange; Socket comprises pressing plate 6, pedestal 8, reed 10, wherein reed 10 is " Y " type, pedestal 8 is provided with the hole that pressing plate 6 and reed 10 are installed, the hole of fixation clip 6 is arranged symmetrically in the upper end of spring leaf hole, be fixed in the pedestal respective aperture after reed 10 and the inserted sheet 1 corresponding arrangement, pressing plate 6 also is fixed in the pedestal corresponding aperture simultaneously.

Described plug is provided with bag sheet 2, and described socket is provided with bag sheet 9, and inserted sheet 1 and reed 10 are fixed in separately in the pedestal by arranging by bag sheet 2 and bag sheet 9 respectively.

Described reed 10 upper center are arc structure dorsad.

Described socket base 8 both ends of the surface and pressing plate 6 junctions are provided with patch 7, are used for vertical fixation clip position, prevent along its pedestal hole play.

Beneficial effect of the present invention:

(1) the utility model connector plugs together that contact does not have the power of plugging together and separating force when separating, so claim zero-force connector;

(2) pressure between connector inserted sheet and the reed is controlled by the pressure of spring clip and the distance that pressing plate moves, as long as in the life span of spring clip spring, all can provide consistent pressure, so the contact of the utility model plugs and sockets reed is reliable, the life-span is long;

(3), rather than lean on the deformation of reed itself to obtain because the contact pressure between the reed derives from spring clip, thus the constant pressure between the reed, lower to the dimension precision requirement of reed, realize easily on the technology.

Embodiment

Below in conjunction with the embodiment accompanying drawing the utility model is described in further detail:

The utility model is made up of plug and socket, wherein plug comprises inserted sheet 1, bag sheet 2, spring clip 3, pin 4, pedestal 5, inserted sheet 1 is by bag sheet 2 spacing being fixed in the pedestal 5, spring clip 3 is vertically fixed in the both ends of the surface of pedestal 5 by pin 4, is symmetrical expression and arranges, this moment, the state of spring clip 3 was a free state, its handle 3b position is under the effect of spring force, for splitting state, hook 3a position is closure state under the effect of spring force.

Socket comprises pressing plate 6, patch 7, pedestal 8, bag sheet 9, reed 10, wherein reed 10 is " Y " type, pedestal 8 is provided with vertical stepped hole that reed 10 is installed, also be provided with the longitudinal hole that two pressing plates 6 are installed simultaneously, reed 10 is fixed in the vertical stepped hole of pedestal by bag sheet 9, pressing plate 6 is fixed on by patch 7 in the longitudinal hole of pedestal correspondence, reclines with the upper end of contact reed 10.Patch 7 restriction pressing plates 6 are with respect to pedestal 8 lengthwise movements.

The middle part of the contact reed 10 of " Y " type is an arc structure dorsad, during butt joint, when pressing plate 6 that two symmetrical expressions of pressing by outside force socket are arranged and plug upper spring press from both sides two handle 3b of 3, the upper end of the contact reed 10 of " Y " type is stressed to be drawn close to the center, the inserted sheet of plug inserts in the Die for Reeds of Connector Jack, realize corresponding being electrically connected, do not have pressure between inserted sheet and the reed this moment.The middle part arc of reed 10 tightly rode on the inserted sheet 1 of plug when butt joint put in place, and open at two of spring clip 3 hook 3a positions simultaneously.The hook 3a position of butt joint rear spring clamp 3 compresses two pressing plates 6 of socket symmetric under the effect of spring force, the normal pressure between the contact that is electrically connected is provided, thus the separation of restriction plug and socket, guarantees stressed evenly, the raising reliability.When need separate plugs and sockets,, from socket, take out plug and get final product as long as dead spring folder 3 separates spring clip and pressing plate 6.
