TH17667A - Protective plug for terminal block or terminal release board - Google Patents

Abstract

The invention involved a protective plug. (1) For the terminal block or terminal release board (4) of the telecommunication system which has provided the grounding joint board (5), it consists of a housing (2) with an overvoltage suppressor. Define (3) and the contact conductor bar (13,14) in order to provide a protective plug (1) that its housing is as small as possible so that it can reach the cable. Cable (39) that is connected on top The cable of the terminal block or the terminal block (4) can be connected even when the protective plug (1) is already inserted inside the protective plug (1), the socket must be provided. (48) Posing along the pole side (28) one pole of the body. The overvoltage (23) is pressed and the grounding joint board (5) is provided with a lug (11) which is inserted into the socket (48) to make the earthing connection of the unit. Press against the overvoltage (23) (Fig. 5).

Claims (9)

1. A protective plug-in assembly for use with terminal blocks or terminal release boards or terminal release boards for telecommunication systems. The plug assembly consists of an earth joint board. And the housing with An overvoltage suppressor and a contact conductor bar, which is used to provide an electrical connection between the terminals.
