Anti-disassembly and power-off protection device and use method

Abstract

The invention discloses an anti-disassembly and power-off protection device and a use method. The anti-disassembly and power-off protection device comprises a connector and a wiring unit detachably connected to the connector. The device further comprises an anti-disassembly shielding plate mechanism, a shaft lock stop mechanism and a switch linkage control mechanism. The anti-disassembly shieldingplate mechanism comprises a shielding plate and an indexing pin, wherein the shielding plate is used for shielding the connection part of the wiring unit and the connector; the shaft lock stop mechanism comprises a shaft lock capable of sliding relative to the rotating shaft and a shaft lock positioning base capable of sliding relative to the shaft lock; the switch linkage control mechanism comprises a rotating shaft; the two ends of the rotating shaft are connected with a cam and an operating handle respectively, wherein the cam is used for driving the travel switch to be opened or closed, and the rotating shaft is provided with a first clamping section, a second clamping section and an annular groove matched with the shaft lock; the shielding plate is provided with a connecting hole matched with the first clamping section; one end of the shielding plate is connected to the rotating shaft through the connecting hole, and the other end is hinged to the wiring unit; and the travel switch and the shaft lock positioning base are connected to the wiring unit. According to the invention, through controlling of the shielding plate, the protection of the connection part of the wiring unit and the connector is realized.

Description

technical field [0001] The invention relates to the technical field of electrical connector protection, in particular to an anti-disassembly and power-off protection device and a use method. Background technique [0002] Anti-dismantlement and power-off protection devices for electrical connections have always been a non-negligible part of electrical equipment. For example, with the rapid development of the rail transit industry, the protection of the junction box installed on the carriage is becoming more and more important. Once the junction box is dismantled by mistake or maliciously, the entire carriage will not be able to operate normally. Therefore, the tamper protection of the junction box is crucial. On the other hand, the junction box in the prior art has no anti-dismantlement mechanism, which is easy to be dismantled by mistake and live work, and has poor safety. In view of the above reasons, an anti-dismantlement and power-off protection device is needed in the p...
