a wire controller

Abstract

The objective of the invention lies in providing a line controller, and mainly solves a problem that a mainboard of a conventional line controller is liable to be affected with damp. The line controller comprises a housing and a mainboard disposed in the housing. The mainboard comprises a mainboard main body and a wiring terminal. The housing is provided with a via hole which is used for the passing of a wire harness so as to connect a wiring terminal. The line controller also comprises an isolation structure, and the isolation structure forms a wiring space which is used for storing the wiring terminal and is communicated with the via hole. The isolation mechanism enables the wiring space to be isolated with the mainboard main body, thereby enabling the wiring space and the space of the mainboard to be separated, effectively prevent damp from entering into a space where the working surface of the mainboard is located through the via hole and affecting the mainboard, and achieving a good damp-proof effect.

Description

technical field [0001] The invention relates to the field of control devices, in particular to a wire controller. Background technique [0002] The existing surface-mounted wire controllers do not have moisture-proof function, or the moisture-proof function is poor, such as figure 1 As shown, the shell 1' of the wire controller is provided with a wire hole 131' and a mounting hole 132'. The above wire controller has the following problems: [0003] 1. If the wire hole 131' is too high, moisture will enter the main board 2' through the wire hole 131' along the line. [0004] 2. The installation hole 132' in the lower right corner is too close to the terminal 22', which will cause corrosion, open circuit or open circuit here. [0005] Both of the above problems can cause motherboard corrosion. [0006] In view of the above problems, it is urgent to provide a new wire controller to solve the problem of poor moisture-proof effect existing in the prior art. Contents of the ...
