TH3348A - Grounding terminal structure for protective device to prevent voltage surges. - Google Patents

Abstract

The substance of this invention provides an earth-termination terminal in a stabilizer that is simple and can be fixed to the ground. To achieve the aforementioned objectives and other matters under this invention The earthing terminal structure has been provided to consist of a block pattern, the earthing terminal on the insulating base, and placed between the insulating insulator inserts under the communication terminal block pattern on the insulating base, terminal plate. The U-shaped earthing end is inserted into the shield insert and is provided with a convex cleat attached to the earth terminal block, and a screw (screw) to secure the terminal block. The earthing end is connected by a convex grit and adjusted to be fixed to the ground wire. Because the U-shaped earthing plate Was brought into the insertion of the guard The lightning arrester contains electrodes. The upper and lower inserts can be adjusted for electrical connections to earth throughout the earthing plate by inserting the shield just into the protective insert, respectively. Any other substance and feature of this invention can be evident from the revelations made following the details of one fine appearance with reference to the illustration.

1. The structure of the grounding terminal for the higher voltage stabilizer used for the subscriber consists of: Insulated base and cover Which the insulator base will be provided with a support base Which extends forward from the lower end of the insulator base so that it has a general L shape. The insulated base has a protective insert. Bottom connector block and top, left and right connector block. The shield insert allows the earthing pad with the grounding contact pad to be positioned on one of the side walls designated as the insertion of the shield. And the grounding pad is placed on the terminal block below. The grounding disc is fixed on the bottom terminal. By a screw that acts as a grounding terminal Has that feature The bottom terminal block extends forward from the lower front end under the center between the upper resistance block of the insulator base. And such shield inserts are made horizontally between the bottom faces of the above, left and right connector blocks. And the aforementioned support The earthing pad consists of an earthed contact pad made of odd flat plates with a common U-shaped hole. And the grounding pad will emerge from the middle portion of the U-shaped grounding contact pad. The grounding terminal plate will rest on the support base. In order to plan the grounding on the bottom terminal block and the left and side connecting blocks. There is an earth contact that extends the arc to the protective insert.
