Kind Code:
A1
Abstract:
Disclosed is a wall bushing, comprising a head portion assembly, a conductive rod, and a connection terminal sealing and covering the head portion assembly and the conductive rod. The connection terminal and the conductive rod are electrically connected. The head portion assembly comprises a transition container and a transition plate connected to each other. The transition container is provided with a first through-hole at the upper end thereof, and is open at the lower end thereof. The transition plate is provided with a second through-hole. The conductive rod passes through the first through-hole and the second through-hole. The transition container and the transition plate are fixedly connected such that an accommodation chamber is formed around the conductive rod in the transition container. The wall bushing has a simple structure and does not require a corrugated pipe, thereby eliminating the need to use dynamic axial sealing equipment, and greatly improving sealing reliability while reducing production costs.
