DETAILED DESCRIPTION

[0039] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0040] An embodiment of the utility model provides a signal power coaxial special-shaped spring pin connector, which can realize the simultaneous transmission of two signals. Specifically, in this embodiment, it is used to simultaneously transmit power signals and communication signals. During the transmission of two different signals, the overall volume is reduced, the space utilization rate is higher, and the distance between the power pin and the signal pin is further shortened, thereby ensuring the stability of signal transmission.

[0041] like Figure 1-5As shown, the signal power coaxial special-shaped spring pin connector provided by the embodiment of the present invention includes a first spring pin 100, a second spring pin 200 and an insulating member 300 coaxially arranged, and the insulating member 300 includes a base 310 and a rod 320, wherein the rod 320 is formed on the base 310 and extends toward the outside, and a mounting hole 321 is provided inside the rod 320 along the axial direction; the first spring pin 100 is sleeved on the rod 320, and the second spring pin 200 is arranged on the lower side of the insulating member 300 and penetrates into the mounting hole 321, the first spring pin 100 includes a first needle tube 110, a first elastic member 120 and a first needle shaft 130, and the first A first inner tube 111 is provided inside the needle tube 110 along the axial direction, penetrating the first needle tube 110, and the first inner tube 111 is sleeved on the rod 320. The first elastic member 120 is provided inside the first inner tube 111 and sleeved on the rod 320. A first through hole 131 is provided inside the first needle shaft 130 along the axial direction, and the first needle shaft 130 is provided inside the first inner tube 111 and sleeved on the rod 320. The lower end of the first needle shaft 130 abuts against the first elastic member 120, and the first elastic member 120 elastically pushes the upper end of the first needle shaft 130 to extend out of the end of the first inner tube 111; the end of the second spring needle 200 extends along the mounting hole 321 and the end of the first through hole 131.

[0042] In this embodiment, the insulating member 300 is made of an insulating material, thereby isolating the first spring pin 100 and the second spring pin 200 to prevent mutual interference of signals. At the same time, the first spring pin 100 and the second spring pin 200 are interconnected through the insulating member 300. That is, the first spring pin and the second spring pin are both assembled on the insulating member, so that two signals can be transmitted simultaneously. In this process, the space size for assembling the connector is reduced, and the distance between the first spring pin 100 and the second spring pin 200 is shortened as much as possible to ensure stable signal transmission.

[0043] When using the connector provided in this embodiment to transmit signals, the first pin shaft 130, under the elastic thrust of the first elastic member 120, extends along the opening of the first inner tube 111, thereby abutting against the mating member to transmit the first signal. Similarly, the second spring pin 200 extends from the mounting hole 321 and the end of the first through hole 131 of the first pin shaft 130, thereby abutting against the mating member to transmit the second signal. By coaxially arranging the first spring pin 100 and the second spring pin 200 on the insulating member 300, two different signals can be transmitted simultaneously, reducing the design space required for the connection installation. Furthermore, by shortening the spacing between the two spring pins, the stability of signal transmission is improved.

[0044] In this embodiment, if Figure 2-4As shown, the first needle tube 110 includes a first bottom portion 112 and a first tube portion 113. The first bottom portion 112 is detachably connected to the base 310. One end of the first tube portion 113 is formed on the first bottom portion 112, and the other end extends outward. The first bottom portion 112 connected to the base 310 further stabilizes the connection between the first needle tube 110 and the insulating member 300. In this embodiment, the width and / or length of the first bottom portion 112 is greater than the diameter of the first tube portion 113, thereby ensuring a stable connection with the base 310 and ensuring the stability of the first spring pin 100.

At this time, the second bottom portion 212 is used to connect to the base 310. It is worth noting that the size of the second bottom portion 212 is also larger than the size of the second tube portion 312, so that the connection stability can be guaranteed during the connection between the second bottom portion 212 and the base 310. Specifically, the second bottom portion 212 and the base 310 are detachably connected; one end of the second tube portion 312 is formed on the second bottom portion 212, and the other end extends toward the opening of the first through hole 131.
