Protection device for communication line interface

Abstract

The invention discloses a protection device for a communication line interface, and the device comprises a communication connector. The central part of the front side wall of the communication connector is fixedly provided with a connector, and the front side wall of the connector is provided with a slot. The lower surface of the inner side wall of the slot is fixedly provided with a contact piece, and an outer side wall of the connector is sleeved by a protection cover. Whether a protection sleeve is needed or not depends on the actual situations: if the connector is a naked connector, the connector can be directly inserted for use without disassembling the protection sleeve. When the device moves a resetting support seat and is clamped, a connecting rod still moves, and drives a clampingblock to move. When the pressure reaches a certain value, a resetting spring will generate a recoil force and will moves in an opposite direction, i.e., driving the connecting rod to move in the opposite direction, and the clamping block will rebound immediately. However, a clamping board clamped with the clamping block will be free of clamping, thereby facilitating the disassembly of the protection cover, and reducing the damages to the communication connector. Moreover, the device can achieve the judgment of whether there is electric leakage at an interface or not, and guarantees the safety.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a protection device for a communication line interface. Background technique [0002] The communication interface generally has the following types: RS-232, RS-485, general network interface, can support PSTN, ISDN and LAN various networking environments, has USB2.0 super high-speed data interface, connects to the computer to back up important image data, It can be equipped with progressive scan VGA output interface, etc. At present, the communication application is very extensive, but the interface of the current communication line is fragile and cannot be used for a long time, and the applicability of the interface is poor and cannot meet people's requirements. Contents of the invention [0003] The purpose of the present invention is to provide a protection device for a communication line interface to solve the problems raised in the above-mentioned background technolo...
