Description

Compact connector

Technical field

The utility model relates to connector technique fields, and in particular to a kind of compact 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 on the market usually requires the spare and accessory parts such as hole seat, needle stand, terminal, stitch, and part comparison is more, volume is opposite Larger, disassembly inconvenience, and the fewer part electronic product requirement connector part the better on the market, volume is the smaller the better, will also be just In disassembly.

Summary of the invention

In order to overcome the shortcomings of background technique, the utility model provides the bar connector of a kind of only hole seat and terminal.

The technical solution of the utility model is: including terminal, hole seat, the terminal is equipped with fixture block, sets in the hole seat Fluted, the fixture block is worked in coordination with groove.

Stitch, needle stand directly are eliminated, terminal is directly welded on circuit boards, is blocked by the cooperation of fixture block and groove Hole seat prevents hole seat from voluntarily deviating from, and utilizes the elasticity capacity of terminal phosphor bronze material when disassembly is desired, makes the fixture block on terminal Reach away from one another with groove variations, finally removes terminal.

In order to improve the deformability of fixture block on terminal, it is equipped with hole in the middle position of the terminal, the terminal is from the beginning Portion curves inwardly 180 degree, and the head that the fixture block is located at terminal curves inwardly at the top of 180 degree, and the fixture block passes through on terminal Hole.A long regulations and parameters is formed by this bending 180 degree, fixture block can be deformed easily.

Preferably, protrusion is equipped between the hole and head on the terminal, the hole seat is equipped with square hole, the terminal Head and protrusion pass through square hole.

Preferably, for the groove in the hole seat at U-shaped, the groove inside of the hole seat is equipped with guiding surface, described to lead It is inclined to inwardly to inclined-plane outer small interior big.

Preferably, the hole seat is equipped with home block.

Preferably, the shape of the home block is semi-cylindrical.

The utility model has the beneficial effects that significantly reduce spare and accessory parts, only hole seat and terminal, convenient disassembly.

Specific embodiment

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

As shown in Fig. 1-Fig. 7, the present embodiment provides a kind of compact connector, including terminal 1, hole seat 2, the terminals 1 It is equipped with fixture block 11, the hole seat 2 is equipped with groove 21, and the fixture block 11 is worked in coordination with groove 21.The hole seat 2 is usually adopted With PA66 material, the terminal 1 generallys use phosphor bronze, since phosphor bronze and PA66 material have good elasticity, when installation Fixture block 11 is set to be caught in groove 21 using the elasticity of material.

In order to increase the elasticity of fixture block 11, it preferably is equipped with hole 12 in the middle position of the terminal 1, the terminal 1 is from the beginning Portion 13 curves inwardly 180 degree, and the head 13 that the fixture block 11 is located at terminal 1 curves inwardly at the top of 180 degree, and the fixture block 11 passes through Hole 12 on terminal 1.Certain fixture block 11 can also increase its elasticity using thinner thickness, but if the whole thickness of terminal 1 If uneven, just it is not easy to will increase some costs using metal plate punching forming technology.

In order to preferably make power when dismantling connection device, it is preferable that be equipped between the hole 12 and head 13 on the terminal 1 Protrusion 14, the hole seat 2 are equipped with square hole 25, and the head 13 of the terminal 1 and protrusion 14 pass through square hole 25.When needing to remove hole When seat 2, as long as deforming terminal 1 by the protrusion 14 in lower terminal 1, fixture block 11 is finally allowed to be deviate from groove 21.

In order to allow terminal 1 to be preferably inserted into hole seat 2 and the easy insertion groove 21 of fixture block 11, it is preferable that in the hole seat 2 On groove 21 at U-shaped, 21 inside 22 of groove of the hole seat 2 is equipped with guiding surface 23, and the guiding surface 23 is towards introversion Tiltedly at outer small interior big, the groove 21 facilitates to increase the elasticity of groove 21 at U-shaped.When hole seat is inserted on the head of terminal 1 13 When 2, the guiding surface 23 will be such that fixture block 11 deforms easily, and as the insertion of terminal 1 is deeper, fixture block 11 and the deformation of groove 21 are got over Seriously, fixture block 11 is finally directed to groove 21 by the guiding surface 23.Certain guiding surface 23 can use straight inclined-plane, circular arc The appearance of each various kinds such as face.

For the ease of the serial number of quick recognition terminal 1, the hole seat 2 is equipped with home block 24.

In order to make the preferably injection molding demoulding of hole seat 2, it is preferable that the shape of the home block 24 is semi-cylindrical, certainly It can be using triangular-section, salient point etc..

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.
