Problems solved by technology

[0002] In the prior art, as the number of power signals passing through the wall increases, more and more insulators are used, while the traditional method is to directly weld the insulators to the board, which will cause great damage to the installation and disassembly of the board. At the same time, due to the difference in the expansion coefficient of the board and the expansion coefficient of the insulator during the high and low temperature test, it is easy to cause virtual welding at the connection point

Embodiment Construction

[0019] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0020] Such as Figure 1~Figure 3 As shown, a power signal through-wall connection device for avoiding short circuit includes: a circuit board 4 , an insulator and a connecting wire 2 . Among them, the insulator is provided with an insulator inner column 1 and an insulator outer column 5 sleeved outside the insulator inner column 1, a small hole is opened on the circuit board 4, the insulator is inserted into the small hole on the circuit board 4, and the connecting wire 2 passes through the hole. Through the inner column 1 of the insulator and welded with the circuit board 4, the connection between the external circuit and the circuit board 4 can be realized, which can avoid the problem of virtual welding at the connection between the circuit board 4 and the insulator caused by thermal expansion and contraction ...

Abstract

The invention discloses a power signal wall through connecting device avoiding short circuit. The power signal wall through connecting device comprises a circuit board, an insulator and a connecting line, wherein a small hole is formed on the circuit board, the insulator is inserted in the small hole on the circuit board, and the connecting line passes through the insulator and is in welding connection with the circuit board. By the power signal wall through connecting device disclosed by the invention, the board is convenient to install and uninstall, and a hidden hazard that a circuit which is externally connected with the insulator and the shell of the insulator is shorted out is eliminated; simultaneously, influences of thermal expansion contraction on a welding part also can be reduced, and the power signal wall through connecting device is convenient to operate and has good practicability.

Description

technical field [0001] The invention relates to a connection device for a power signal passing through a wall, in particular to a connection device for a power signal passing through a wall to avoid short circuit. Background technique [0002] In the prior art, as the number of power signals passing through the wall increases, more and more insulators are used, while the traditional method is to directly weld the insulators to the board, which will cause great damage to the installation and disassembly of the board. At the same time, due to the difference in the expansion coefficient of the board and the expansion coefficient of the insulator during the high and low temperature test, it is easy to cause virtual welding at the connection point. Contents of the invention [0003] The purpose of the present invention is to provide a power signal through-wall connection device that avoids short circuit, which not only facilitates the installation and disassembly of the board; ...
