Picture 1-4 with a kind of coil spring terminal connecting structure provided by the utility model shown in 10-11, comprising:
Male terminal 1 is fixed with nesting 11, described nested 11 thereon and is set on the carrying protrusion disk 12 of male end；
Female terminal 2, end sleeve are equipped with female end shell 21, are equipped in the female end shell 21 several for fixed with 1 son of male end
And conductive coil spring 211, it is fixed that the female end shell 21 was connected with female terminal 2 is arranged end is equipped with for fixing coil spring first
Ring 212 is equipped with the elastic regulatory component of control coil spring in one end that the female end shell 21 connects with male terminal 1；
The regulatory component includes:
The fixed lid 213 of the coil spring being fixedly mounted in female end shell 21；
The second fixed ring 214 connecting with coil spring 211,214 two sides of the second fixed ring, which are equipped with, adjusts protrusion 215,
Second fixed ring 214 can be free to slide to play the elastic effect of control coil spring 211 in the fixed lid 213 of coil spring；
It is opposite with one end that female terminal 2 is connected to each other on described nested 11 to be equipped with wedge-shaped opening 111, with the second fixed ring 214
Adjusting protrusion 215 match；
Working principle: the insertion end of male terminal 1 is aligned and is inserted into female terminal 2；When insertion, nesting 11 is directed at female end shell
21, and the adjusting protrusion 215 of the second fixed ring 214 is directed at wedge-shaped opening 111；Male end head enters in coil spring 211, but also
It is not contacted with spring silk, next continuing into male terminal, with the insertion of male terminal, adjusts protrusion 215 in wedge shape
The limit sliding groove of mouth 111 will drive the rotation of the second fixed ring 214, since the second fixed ring 214 is connected with coil spring 211, with
The rotation of the second fixed ring 214, coil spring 211, which twists, simultaneously to be tightened, and the diameter of cylinder that coil spring 211 forms becomes smaller, thus by public
Terminal is stuck in female terminal, and common coil spring terminal has with coil spring in the process to be contacted and have sliding friction: sliding friction
It will increase male terminal, the abrasion of spring silk table face electroplated layer reduces service life, reduces electrical connection performance；Also compare when extraction
It is convenient, it directly extracts, adjusts the drum diameter that protrusion 215 forms coil spring 211 under the reversed drive of wedge-shaped opening 111
Become larger, then without lifting an eyebrow and undamaged extraction by male terminal 1；
It is compared such as into and out stress condition in the process and traditional form coil spring terminal into and out process stress
Shown in Figure 10~11.
The advantages of this coil spring terminal connecting structure, is that the male terminal and female terminal of the utility model are not the mistakes after insertion
Be full of connection, thus male terminal 1 and female terminal 2 dock and withdrawal process in terminal zero insertion force, only male terminal 1 can be achieved
After being inserted in place, since coil spring 211 can just tighten package male terminal 1, to provide enough retentivities, therefore even if make for a long time
With that the case where connection shakiness, loosening will not occur, will not occur showing the case where plug has some setbacks because long-time connects.Because
Have no frictional force in docking and withdrawal process, so the abrasion of male terminal 1 and coil spring 211 can bottom out,
To increase the service life of male and female terminal 2.
In above-mentioned technical proposal, as seen in figs. 5-6, the female end shell 2 is double-layer structure, inner casing 22 and shell 23 it
Between distance match with nested 11 thickness, it is opposite on the inner casing 22 to open up that there are two the wedge-shaped openings with nested 11
111 square breach 112 to match make nesting 11 smooth during insertion in female end shell 21, simultaneously using double-layer structure
Square breach 112 can also guide the adjusting protrusion 215 of the second fixed ring 214, improve docking efficiency.
In above-mentioned technical proposal, as illustrated in figs. 5-7, opened up vertically on the inner wall of the shell 23 of the female end shell 21 limited
Position slot 231, nested 11 outer wall are equipped with the positive stop strip 115 to match with the limiting slot 231 of shell 23, the mesh of this design
Be to assist docking for male terminal 1 and female terminal 2, make nested 11 to be properly inserted female end shell 21.
In above-mentioned technical proposal, as shown in figure 8, the bottom of nested 11 wedge-shaped opening 111 is equipped with a V-arrangement barb mouth
113, after the insertion of male terminal 1, it can will will adjust protrusion 215 and be caught in V-arrangement barb mouth 113, and prevent it due to acutely shaking
It falls off.
In above-mentioned technical proposal, as Figure 8-9,23 bottom of shell of the female end shell 21 is equipped with annular groove 231, institute
It states and offers annular bar hole 2311 on the side wall of annular groove 231, be equipped with and 231 shape phase of annular groove in the annular groove 231
The annular strip 2312 matched, can be free to slide in annular groove 231, and the annular strip 2312 is equipped with control protrusion
2313, it is stretched out from the annular bar hole 2311 so that user controls annular strip 2312, design can be consolidated second
It is directly locked to determine ring 214, causes connection to fall off to prevent it from turning round.
In above-mentioned technical proposal, as Figure 8-9, one end in the annular groove 231 is equipped with top and stretches spring 2314, makes
The annular strip 2312 is constantly in limit state, and 2314 means of complementary annular strip 2312 of spring is stretched for the second fixed ring 214 in top
Position it is locked, to guarantee the elastic of coil spring 211.
In above-mentioned technical proposal, rubber dust-proof skin is connected between the inside and outside shell of the female end shell 21, prevents dust from entering
And influence the using effect of terminal.
Number of devices and treatment scale described herein are the explanations for simplifying the utility model.To the utility model
The application of coil spring terminal connecting structure, modifications and variations will be readily apparent to persons skilled in the art.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
