Anti-bending twin-lock connector

Technical field

The utility model relates to connector technique fields, and in particular to a kind of anti-bending twin-lock connector.

Background technique

Connector is a kind of component most basic in our electronic engineering technologies.It is blocked place or isolated in circuit Between obstructed circuit, the bridge of communication is erected, current flowing is made to reach transmission electric current or signal purpose, realizes circuit predetermined Function.Connector its terminal on the market is not connected firmly with stitch at present, vibration, transport, the movement such as use when be easy general Stitch bending and terminal and stitch are deviate from, and can fracture after the multiple bending of stitch, eventually lead to high speed connector failure.Simultaneously Portioned product to connector require hole seat and needle stand clasp it is very tight, be difficult to the requirement deviate from, wanted currently on the market without meeting The connector asked.

Summary of the invention

In order to overcome the shortcomings of background technique, the utility model, which provides, a kind of can prevent stitch from bent and hole seat and needle simultaneously Seat clasps very tight anti-bending twin-lock connector.

The technical solution of the utility model is: including terminal, hole seat, needle stand, stitch, 90 degree of the terminal left and right sides is curved Song has left wall and right wall, and the left wall and right wall are at S type, and the left wall and right wall are mutually symmetrical with, mutually fit, the needle stand First bottom surface is equipped with first hole, and the second bottom surface of the hole seat is equipped with second hole, and one end of the stitch is successively worn Cross first hole, second hole is inserted between left wall and right wall, the terminal is mounted in hole seat, and the hole seat and needle stand are mutual It matches.

The left wall and right wall of the terminal have good clamping force using S type, can compress stitch, reduce stitch from terminal Middle abjection and reduction contact resistance.

Stitch bent in order to prevent, and the stitch is at 90 degree of bendings, and two sides are equipped with anti-bending on the first bottom surface of the needle stand Baffle, the shape of the anti-bending baffle are square.

Preferably, the terminal is equipped with acclivitous elastic slice, is equipped with angle inside the hole seat, the hole seat it is oblique Mouth back is equipped with inverted l-shaped structure.

Preferably, two side bottom of hole seat is equipped with hook, and the hook one is fixed in hole seat, and the hook is in addition One hanging, and the hook is equipped with oblique wave and chuck, and the needle stand two sides are equipped with rectangular hook groove, the inclined-plane court of the oblique wave To the inside of needle stand, the chuck is snapped connection mutually towards the outside of needle stand, the chuck with hook groove.

Preferably, the head of the hook is equipped with boss.

Preferably, mark platform is additionally provided in the hole seat.

Preferably, the shape of the mark platform is semicolumn.

Preferably, the needle stand is equipped with latch hook.

The utility model has the beneficial effects that improving terminal and stitch connective stability, stitch is not easy to curve, hole seat with Clasping for needle stand is tightly not easy voluntarily to deviate from very much.

Specific embodiment

The embodiments of the present invention are described further below for attached drawing:

As shown in figs. 1-9, the present embodiment provides a kind of anti-bending twin-lock connectors, including terminal 1, hole seat 2, needle stand 3, needle Foot 4, the 1 90 degree of bendings in the left and right sides of terminal have left wall 11 and right wall 12, and the left wall 11 and right wall 12 are at S type, the left side Wall 11 and right wall 12 are mutually symmetrical with, mutually fit, and the first bottom surface 31 of the needle stand 3 is equipped with first hole 32, the hole seat 2 The second bottom surface 21 be equipped with second hole 22, one end of the stitch 4 sequentially pass through first hole 32, second hole 22 be inserted into To between left wall 11 and right wall 12, the terminal 1 is mounted in hole seat 2, and the hole seat 2 is worked in coordination with needle stand 3.The terminal 1 left wall 11 and right wall 12 have good clamping force using S type, can compress stitch, reduce stitch deviate from from terminal and The material of reduction contact resistance, the terminal 1 and stitch 4 preferentially selects phosphor bronze, and good conductivity, elasticity is good.

Stitch bent in order to prevent, and the stitch 4 is at 90 degree of bendings, and two sides are equipped on the first bottom surface 31 of the needle stand 3 Anti-bending baffle 33, the shape of the anti-bending baffle 33 are square.The anti-bending baffle 33 may be cylindrical or described It is not arranged in two sides on first bottom surface 31 of needle stand 3, and the anti-bending baffle 33 of a bulk entirety is set.

It is preferably put into when in order to install and when dismantling connection device preferably makes power, it is preferable that the terminal 1 is equipped with Acclivitous elastic slice 13, angle 23 is equipped with inside the hole seat 2, and 23 back of angle of the hole seat 2 is equipped with inverted l-shaped structure 24.Angle 23 guides the deformation of elastic slice 13 when installation, and when the elastic slice 13 on terminals 1 being waited to pass through angle 23 completely, elastic slice 13 starts Rebound, elastic slice 13 is bound to 23 back of angle and is equipped in inverted l-shaped structure 24, so that inverted l-shaped structure 24 be made to block the anti-not-go-end of angle 23 Son 1 is voluntarily deviate from.

In order to allow hole seat 2 and needle stand 3 to clasp and more step up, it is preferable that 2 liang of side bottoms of the hole seat are equipped with hook 25, The hook 25 1 is fixed in hole seat 2, and the hook 25 other one hanging, and the hook 25 is equipped with 26 He of oblique wave Chuck 27,3 two sides of needle stand are equipped with rectangular hook groove 34, and the inclined-plane of the oblique wave 26 is towards the inside of needle stand 3, the chuck 27 snap connection mutually towards the outside of needle stand 3, the chuck 27 with hook groove 34.When hole seat 2 is initially inserted into needle stand 3, hook Oblique wave 26 on 25 guides hook 25 to start to deform, and when oblique wave 26 passes through hook groove 34 completely, hook 25 starts to spring back, and allows card Platform 27 blocks hook groove 34 and voluntarily deviates from so as to avoid hole seat 2 and needle stand 3.

In order to preferably remove hole seat 2 from needle stand 3, the head of the hook 25 is equipped with boss 28, increases hand and hole The frictional force of seat 2 and better pressing hook 25 make its deformation.

For the ease of the serial number of quick recognition terminal 1 and stitch 4, mark platform 29 is additionally provided in the hole seat 2.

In order to make the preferably injection molding demoulding of hole seat 2, the shape of the home block 24 is semi-cylindrical, naturally it is also possible to be used Triangular-section, salient point etc..

Portioned product has higher requirement to the anticreep of hole seat 2 and needle stand 3, then just needing to increase hole seat 2 and needle stand 3 Tightening force, the needle stand 3 be equipped with latch hook 35, when future needing to increase tightening force, the latch hook 35 on needle stand 3 can be used to buckle Tightly, it is only necessary to increase a hook 25 to match each other with hole seat 2 in hole seat 2.

The present embodiment is not construed as the limitation to utility model, but changes made by any spirit based on the utility model Into should all be within the protection scope of the utility model.
