The needle sleeve main body 7 comprises a second front end, a second fixed flange and a second tail end which are connected in sequence; wherein: an inner cavity is arranged in the second front end, the conductive sleeve ring 5 and the compensating spring 6 are arranged in the inner cavity from front to back, and the conductive thimble 4 can be inserted into the inner cavity to be in contact with the conductive sleeve ring 5; an outer convex column is formed at one end of the conductive thimble 4 far away from the conductive lantern ring 5, and one end of the compensation spring 6 is sleeved and fixed on the outer convex column; a counter bore is arranged at one end of the conductive thimble 4 close to the conductive sleeve ring 5, and the conductive thimble 4 and the first front end of the needle end main body 2 can be inserted into the counter bore and contacted with the conductive sleeve ring 5.
In summary, the first end of the needle end body 2 and the second end of the needle sleeve body 7 are connected to the modular electrical components by the conductive wire 1, and when the connection between two adjacent modular electrical components is realized, the pin portion is inserted into the socket portion:
