The lower end of the probe 52 is accommodated in the accommodating cavity 501 of the sleeve 50 , and the upper end of the probe 52 extends out of the opening 503 of the sleeve 50 . After the spring 54 is placed in the receiving cavity 501 , its lower end abuts against the bottom of the accommodating cavity 501 , and its upper end abuts against the inner top of the accommodating cavity 521 of the probe 52 . When the probe 52 is pressed, as shown in FIG. 1 b , the spring 54 is deformed, so that the probe 52 can slide up and down in the accommodating cavity 501 .

However, after the spring 54 is placed in the accommodating cavity 501, its upper end is accommodated by the accommodating cavity 521 of the probe 52, and there is still a large gap around the accommodating cavity 501 where its lower end is located, and the lower end of the spring 54 is located in the accommodating cavity 521. The base is concave, and like this, when the spring 54 is deformed under pressure, because the lower end of the spring 54 does not have a resisting part to resist and support, the deformation of the spring is relatively large, and the elastic force is unstable. Cause elastic fatigue, thereby reducing the service life of the product. In addition, since the elastic force of the spring is unstable, it is difficult to control the amount of depression of the probe 52, thereby affecting the stability of electrical conduction.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIGS. 2-4 , the probe connector 100 of the present invention includes a sleeve 1 , a probe 2 , a spring 4 and a resisting member 5 .

Specifically, the sleeve 1 is a hollow structure, and the hollow structure forms an accommodating cavity 15, the upper end of the sleeve 1 is provided with a through hole 11 communicating with the accommodating cavity 15, and the lower end of the sleeve 1 is connected to There is a closed base 13. Specifically, the upper end of the sleeve 1 is bent and extended toward the accommodating cavity 15 to form a stop portion 12 , the stop portion 12 has an opening, and the through hole 11 is formed by the opening.

The probe 2 has a sliding portion 25 and a contact portion 23 protruding upward from the sliding portion 25 . Specifically, the sliding part 25 is slidably accommodated in the accommodating cavity 15 of the sleeve 1 and can be held by one end of the sleeve 1. The end of the contact part 23 is roughly hemispherical, and passes through the through hole 11. And protruding out of the sleeve 1 , the sliding portion 25 defines a groove 21 communicating with the accommodating cavity 15 . Specifically, as shown in FIG. 4 , the bottom of the groove 21 is tapered.

The resisting member 5 is accommodated in the receiving cavity 15 and carried on the base 13 . The resisting member 5 defines a receiving cavity 51 communicating with the receiving cavity 15 .

The upper end of the spring 4 is in contact with the groove 21 of the probe 2 , and the lower end of the spring 4 is accommodated in the receiving cavity 51 of the resisting member 5 . In this embodiment, the accommodating cavity 51 is a through structure, and the lower end of the spring 4 passes through the accommodating cavity 51 and interferes with the base 13 . Specifically, the resisting member 5 in this embodiment is in the shape of a metal ring. The resisting member 5 of the metal ring structure can resist and support the spring 4, and the detailed description will be given below. The assembly action of the above structure will be described in detail below.

Referring to Figures 3 and 4, the resisting member 5 is first placed in the housing cavity 15 of the sleeve 1, and then the spring 4 is also placed in the housing cavity 15, and the lower end of the spring 4 is accommodated in the resisting member 5 in the housing chamber 51. Then, after the sliding portion 25 of the probe 2 is loaded from the top of the sleeve 1, the upper end of the sleeve 1 is pressed inwardly to form a stop portion 12 that bends and extends slightly toward the accommodating cavity 15. At this time, the spring 4 The upper end touches the groove 21 of the probe 2 , and the lower end passes through the receiving cavity 51 of the resisting member 5 and touches the base 13 . Therefore, the spring 4 provides an upward elastic force, and the probe 2 is stretched by the elastic force of the spring 4 so that its contact portion 23 protrudes outside the through hole 11 of the sleeve 1, and its sliding portion 25 is blocked by the stop portion 12 of the sleeve 1 Hold, so that it is locked in the accommodation cavity 15 and can slide in it, and will not slip out from the through hole 11. Then, the probe 2 and the sleeve 1 are connected together.

FIG. 5 is a reference diagram of the use state of the probe connector 100 of the present invention. As shown in the figure, when the utility model is in use, the probe 2 moves downward due to the pressure from the contacted object 31, and the spring 4 is compressed accordingly. At this time, the contact part 23 of the probe 2 is against the inner wall of the sleeve 1, and the electric energy can be transmitted to the sleeve 1 through the abutment of the probe 2, and then transmitted to the circuit board (not shown in the figure), so that the current is quickly conducted .

The lower end of the spring 4 passes through the receiving cavity 51 of the resisting member 5 and then abuts against the base 13 . At this time, the gap between the spring 4 and the cavity wall of the accommodating cavity 15 becomes smaller. When the spring 4 is deformed, the resisting member 5 plays a role of resisting and supporting at its lower end, thereby preventing the deformation of the spring 4 from being too large. The spring force is stabilized, thus increasing the life of the product. In addition, since the elastic force of the spring is stable, the amount of depression of the probe 2 is easy to control, thereby improving the stability of electrical conduction.

6, 7 and 8 are respectively a perspective view, an exploded perspective view and a cross-sectional view along line B-B shown in FIG. 6 of the second embodiment of the probe connector 100 of the present invention. The difference between this embodiment and the first embodiment is that the accommodating cavity 51 of the resisting member 5 is a blind hole structure. More specifically, the resisting piece 5 is a metal piece with blind holes. As shown in FIG. 8 , the lower end of the spring 4 is accommodated in the receiving chamber 51 of the blind hole structure, and is in contact with the bottom of the receiving chamber 51 . Specifically, the bottom of the receiving cavity 51 is conical. The lower end of the spring 4 is accommodated in the blind hole metal part. The function of the receiving chamber 51 of the resisting part 5 of the blind hole structure is consistent with that of the resisting part 5 of the metal ring structure in the first embodiment. When the probe is connected During the working process of the device 100, when the spring 4 is deformed, it can also prevent the deformation of the spring 4 from being too large, so that the elastic force of the spring 4 is stable, thereby improving the life of the product. In addition, since the elastic force of the spring 4 is stable, the amount of depression of the probe probe 2 can be easily controlled, thereby improving the stability of electrical conduction. In addition, the bottom of the accommodating cavity 51 of the blind hole structure is tapered, and the non-horizontal bottom surface can make the spring 4 on it slightly inclined, which is beneficial to the stopper between the contact portion 23 of the probe 2 and the sleeve 1 Electrical conduction between the inner walls of the portion 12.

In summary, the probe connector 100 of the present invention is provided with a resisting member 5 in the accommodation cavity 15 of the sleeve 1, and the resisting member 5 is carried on the base 13, and is provided with the accommodation cavity 15 The connected receiving cavity 51. The accommodating chamber 51 of the resisting member 5 accommodates the lower end of the spring 4 to resist and support, thereby preventing the deformation of the spring 4 from being too large, making the elastic force of the spring 4 stable, and thus improving the life of the product. In addition, since the elastic force of the spring 4 is stable, the amount of depression of the probe 2 is easy to control, thereby improving the stability of electrical conduction.
