Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic structural view of a flexible contactor according to an embodiment of the present invention.

Wherein, one side of the base 110 is provided with two guide rails 111 extending outwards; the first insulating housing 120 and the second insulating housing 140 are nested on the two rails 111; the first spring 130 is connected to one side of the first insulating case 120 and one side of the second insulating case 140 through the first guide post 131, respectively; the second spring 150 is disposed in a guide hole provided at the other side of the second insulating case 140, and one end of the second spring 150 is connected to the copper contact 160; the driving unit 180 is used for driving the first insulating housing 120 and the second insulating housing 140 to move on the two guide rails 111 so as to drive the copper contacts 160 to move; a distance measuring sensor 170 is disposed at one side of the first insulating housing 120, and the distance measuring sensor 170 is used to detect the amount of expansion and contraction of the first spring 130 to obtain the butting pressure of the flexible contactor 100.

When the copper contact 160 is not connected to the device to be connected, neither the first spring 130 nor the second spring 150 is stressed.

Therefore, various flexible angle ranges can be met through the design of the conical surface guiding and limiting structure, and the stable contact of the connector at each position is guaranteed.
