Sexual conduction; at this time, as shown in FIG. 5, the thimble 20 is subjected to the contact pressure of the butt end 5 The inside of the accommodating portion 12 is displaced downward, and although the elastic member 3 is pressed, since the needle 20 and the elastic member 3 are still blocked by the electrical barrier member 4, the above electrical conduction does not pass. The elastic element 3 (whether or not the elastic element 3 is a conductive material) is electrically conductive only through the conductive terminal 21 on one side, and since the path of the electrical conduction is short and direct, the inductance can be avoided. The effect can be applied to the transmission of high-frequency signals or high-frequency power, and has a good transmission effect. At the same time, in consideration of factors such as the elastic fatigue and the number of reciprocating times of the elastic member 3, any material (including a conductive material) may be used as the material of the elastic member 3 without being affected by the material.

Furthermore, as shown in FIG. 6 and FIG. 7 , since the electrical barrier 4 is coated and bonded to the joint portion 201 of the thimble 20, the inner wall of the electrical barrier 4 and the accommodating portion 12 can be used. The sliding contact and the sliding engagement of the electrical barrier 4 with the accommodating portion 12 restrict the upper and lower elastic displacement of the thimble 20. In this way, since the electrical barrier 4 cannot be made of a conductive material, it is not made of a hard metal, and can usually be made of an insulating material such as plastic. Therefore, the same material can be used as the insulating body 1 so that it is in sliding contact. The wear can also be reduced so that the thimble 20 should maintain precision and stability in the movement of the telescopic movement and avoid affecting the contact effect.
