Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the contact for the live detection equipment of the power distribution controller is as follows:

referring to fig. 1-4, a contact for a live line detection device of a power distribution controller comprises a first contact piece 1, a second contact piece 2 is arranged on one side of the first contact piece 1, the upper side and the lower side and the left side and the right side of the first contact piece 1 are symmetrically arranged, the upper side and the lower side of the two sides of the first contact piece 1 are respectively connected with the second contact piece 2 in a fitting manner, so that the connection stability is improved, a first gap 3 is formed between the first contact piece 1 and the second contact piece 2, a third contact piece 4 is arranged on one side of the second contact piece 2 away from the first contact piece 1, the two sides of the second contact piece 2 are connected with the two sides of the third contact piece 4 in a fitting manner, so that the connection stability is improved, a second gap 5 is formed between the second contact piece 2 and the third contact piece 4, a round hole 6 is arranged inside the third contact piece 4, round hole 6 has all been seted up to the inside of first contact 1 and second contact 2, and set up on same axis with round hole 6 that third contact 4 was seted up, the heat-sinking capability is improved, the both ends of third contact 4 are equipped with arc edge 7, arc edge 7's inside is connected with the equal laminating in both ends of first contact 1 and second contact 2, the stability of connection is improved, the both sides fixedly connected with contact rod 8 of third contact 4, arc edge 7's outside butt has fixed block 9, contact rod 8 pegs graft in the inside of fixed block 9, and extend to the outside of fixed block 9, and convenient to use, the both ends of two upper and lower third contacts 4 of fixed block 9 block, the stability of connection is improved, the upper and lower both sides of fixed block 9 all are equipped with arch 10.

The working principle is that the upper part and the lower part of the two sides of the first contact piece 1 are respectively connected with the second contact piece 2 in an attaching mode, and the two sides of the second contact piece 2 are connected with the two sides of the third contact piece 4 in an attaching mode, so that a parallel structure is formed among the first contact piece 1, the second contact piece 2 and the third contact piece 4, the current sinking capacity of the contact can be increased, the internal resistance can be reduced, and the loss of electric energy is reduced.
