Waterproof wall wiring structure

Technical Field

The utility model relates to the technical field of wiring, in particular to a waterproof through-wall wiring structure.

Background

At present, the need to pass through the wall plate for the current supply and the connection of electrical equipment is generally achieved by means of cables. However, there are more and more occasions where it is necessary to extend the terminals directly through the wall plate to the outside of the tank. For example, in an electrochemical treatment apparatus, the powered device is inside the apparatus and is in water for long periods of time, while the power source is outside the apparatus. From an economic perspective, the connection of the powered device to the power source should preferably be made directly through the equipment wall. The prior art generally provides a waterproof method by providing an elastic sealing member made of plastic material or by sealing a joint with a sealant. Such a waterproof structure has the following problems: 1. the waterproof effect is realized by clamping the sealing element, and the requirement on the fit tolerance among the opening, the sealing element and the copper bar is high; 2. the sealing element or the sealant is easy to age after a long time, so that the sealing effect is difficult to ensure; 3. the bonding strength is low, so that the wiring cannot bear large tensile force.
