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.

Referring to fig. 1 to 4, the present invention provides a technical solution: an SF6 gas density relay junction box comprises a base 2, a wiring terminal 3, a cover 4, a circuit board 7, a conductive column 8 and a shell 9, wherein the shell 9 is arranged at the top end of the base 2;

the shell 9 is made of polycarbonate, and the shell 9 and the conductive column 8 form an integrated structure through pouring;

the shell 9 is made of polycarbonate and is of a pouring integrated structure with the shell 9 through the conductive posts 8, so that gaps are effectively avoided, and the water and oil leakage prevention is greatly improved;

a mounting plate 1 is arranged at one end inside the shell 9, and a plurality of conductive columns 8 are uniformly arranged at the upper end of the mounting plate 1;

the number of the conductive posts 8 is 10, and the conductive posts 8 are made of brass;

the number of the conductive columns 8 is 10, so that one more junction box can be avoided, on one hand, the hidden danger of water inflow and oil leakage is increased by adding one more junction box, on the other hand, the cost is increased, and in addition, the wiring is inconvenient;

and a circuit board 7 is arranged at the middle position inside the shell 9;

a plurality of through holes 6 are uniformly formed in the circuit board 7, and the conductive posts 8 and the wiring terminals 3 are in one-to-one correspondence through the through holes 6 formed in the circuit board 7;
