Description

Board to board connector

Technical field

The present invention relates to a kind of board to board connector that computer product internal signal circuit such as hand-held electronic product such as mobile phone, digital camera or NB PAD connect usefulness that is used for.

Background technology

The board to board connector of usefulness is the single-point type contact or the way of contact of two point formula in the market, and these two kinds of ways of contact are poor aspect the contact fixing, and when product received the extraneous vibration impact, product was prone to produce the hit phenomenon;

Board to board connector in the market, it all is the tight mechanism of monolock that its public female fastening engages, and product is when receiving the vibratory impulse in the external world, and the female head of product public affairs is easy to break away from cause breaking and interrogates;

Board to board connector in the market; Just there is protruding guiding structural in the guiding that its public female head fastens process in the longitudinal direction, can only realize the homing guidance effect of length direction, does not have protruding guide mechanism at Width; The guiding effect of Width is relatively poor; In a public female insertion process, be easy to cause the plastics on female head width direction to be collapsed by pressure, cause product function to lose efficacy.

Summary of the invention

In view of the deficiency that prior art exists, the invention provides a kind of bikini way of contact, the tight mechanism of twin-lock, have the board to board connector of guidance function in the length and width direction.

The present invention is for realizing above-mentioned purpose; The technical scheme that is adopted is: a kind of board to board connector; Comprise public head connector and female connector; It is characterized in that: said public head connector comprises public head end, a public plastic cement main body, and said public head end one end is the U-shaped lamellar body, and the other end that is shaped to one with U-shaped lamellar body one side is horizontally disposed the connection to use the wiring lamellar body; On a side of U-shaped lamellar body, be provided with locking and use groove, use another side of the U-shaped lamellar body of groove symmetry to be offset formula stay with locking; A said public affairs plastic cement main body is a cuboid, on cuboid, is provided with bar-shaped trough, on the plastic body of bar-shaped trough both sides, is respectively equipped with the public head end pilot trench that several communicate with the cuboid bottom surface, and three of the plane angles are guiding surface on the two ends of cuboid; Several pieces public head end are separately positioned in several public head end pilot trench that a public plastic cement main body is provided with and take shape in one with a public plastic cement main body; Said female connector comprises female head end, a female plastic cement main body; Said female head end one end is the U-shaped body; In the U-shaped body, be provided with three protruding contacts; Body formed with U-shaped for the other end of one is horizontally disposed the connection to use the wiring body, be provided with a protruding post in horizontally disposed connection on the wiring body, on a side of protruding post, be provided with a location with protruding;

A said mother plastic cement main body is a cuboid; On cuboid, be provided with rectangular recess; In rectangular recess, be provided with strip projected parts; Two sides of strip projected parts and with two corresponding rectangular recess in side of strip projected parts in the both sides cell wall on and on the face of the plastic body of rectangular recess both sides; Be respectively equipped with female head end pilot trench that several communicate with the cuboid bottom surface, be equipped with in the female head end pilot trench of several on the plastic cement dignity of both sides with protruding post on the location that is provided with use groove with protruding corresponding location; The two ends, top and bottom of cuboid are boss, and three angles in two boss above the cuboid are for guiding the inclined-plane into; Several said female head end are embedded in respectively in several female head end pilot trench that a female plastic cement main body is provided with and are connected together with a female plastic cement main body;

Said public head connector is plugged on the female connector.

Characteristics of the present invention are: the locking that the sub-U-shaped lamellar body of public head end is provided with is with the bikini contact structures design of groove, offset formula stay and U-shaped lamellar body bottom face; Can be good at guaranteeing the reliability that contacts with the bikini of three protruding contacts being provided with in the female connector U-shaped body; And 3 contacts all are Elastic Contact, receive the vibration in the external world, have the effect that keeps continuing contact when impacting for product; The locking that public head end is provided with is with groove and the offset formula stay tight mechanism of formation twin-lock that contacts with two protruding contacts that are provided with on the sub-U-shaped body of female head end is interior; Can be fine plug sensation during the raising assembling; Product receives extraneous vibration synchronously; Public female contact jaw is difficult for separately improving the strong degree of product contact greatly during impact; Female three the interior angles of two boss above the plastic body are the design of guiding the inclined-plane into; The guiding effect that possesses the length and width direction; Be used with three guiding surfaces on the public plastic cement main body, have and reduce the frictional force that public head connector is plugged on the mutual timing of female connector, product is joined under the state busy; Can automatic capturing, the length and width direction all has the effect of homing guidance.
