DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Please refer to Figs. 1-3 The utility model discloses a kind of probes for power test, including sleeve 1 and probe connector 2, one end of the probe connector 2 is provided with movable rod 24, the end of movable rod 24 away from probe connector 2 extends to the inside of sleeve 1, movable rod 24 surface movably sleeved with nut 23 located in the inside of sleeve 1, the inside of sleeve 1 is provided with linear bearing 14 movably sleeved with movable rod 24 surface.

[0023] Specifically, the probe connector 2 is provided with a coarse thread segment 21, and the movable rod 24 is provided with a fine thread segment 25 threadedly sleeved with the nut 23. The coarse thread segment 21 is used for connecting probe heads of different specifications, has high rotation speed and high structural strength, and is convenient to operate. The fine thread segment 25 is used for connecting with the nut 23 and has high adjustment accuracy, thereby facilitating accurate adjustment of the height of the probe connector 2.

[0024] Specifically, the probe connector 2 is provided with a limiting table 22 at one end, and the movable rod 24 is arranged on the side of the limiting table 22 away from the connector 26. The limiting table 22 is used for limiting the rising height of the movable rod 24. The probe connector 2, the limiting table 22 and the movable rod 24 are integrally formed, thereby ensuring the overall structural strength of the product.

[0025] Specifically, the diameter of the limiting table 22 is greater than the diameter of the connector 26, the diameter of the movable rod 24 is less than the diameter of the limiting table 22, and the diameter of the movable rod 24 is greater than the diameter of the connector 26.

[0026] Specifically, one end of the sleeve 1 is provided with a sink groove 11, and the inside of the sleeve 1 is provided with a through hole 15 located on one side of the limiting groove 12. Both ends of the through hole 15 are provided with a flared portion 16. The sink groove 11 and the through hole 15 are used for connecting a mold for driving a probe.

[0027] Specifically, the inside of the end of the sleeve 1 away from the sink groove 11 is provided with a limiting groove 12. The inner wall of the limiting groove 12 is hexagonal. The outer part of the nut 23 is hexagonal. The end of the movable rod 24 away from the limiting table 22 is provided with a connector 26. The outer diameter of the nut 23 is less than the inner diameter of the limiting groove 12. The outer part of the nut 23 does not directly contact the inner wall of the limiting groove 12. Only when the movable rod 24 is rotated, the hexagonal part of the nut 23 is in contact with the hexagonal inner wall of the limiting groove 12 to limit the nut 23, thereby avoiding rotation of the nut 23. Thus, the position of the nut 23 is adjusted. After the position of the nut 23 is adjusted, the descending height or the rising height of the movable rod 24 can be adjusted.

[0028] Specifically, the outer part of the connector 26 movably sleeves a spring 27. The spring 27 continuously applies a resilient contact force to the movable rod 24, so that the movable rod 24 can quickly descend and reset after being pressed to rise.

[0029] Specifically, a compensation block 13 is fixedly sleeved in the inside of the limiting groove 12, and the outer part of the linear bearing 14 is sleeved with the inside of the compensation block 13. Since the inner wall of the limiting groove 12 is hexagonal and the outer part of the linear bearing 14 is circular, the compensation block 13 compensates the corners in the inside of the limiting groove 12. The outer part of the compensation block 13 is hexagonal, and the inside of the compensation block 13 is circular.

[0030] In summary, compared with the existing probe that cannot independently adjust the height on the market, the power test probe limits the nut 23 through the limiting groove 12, adjusts the position of the nut 23 through the rotating movable rod 24, realizes the adjustment of the descending height or the ascending height of the movable rod 24, and the nut 23 is located in the inside of the sleeve 1, the appearance is beautiful, the fine thread section 25 has high adjustment precision, the height of the probe connector 2 is conveniently and accurately adjusted, the coarse thread section 21 has high rotating speed and high structural strength, the operation is more convenient, and the usability of the product is guaranteed.

[0031] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
