Abstract

The present invention provides a mini MSD (Manual Service Disconnector). The structure of the mini MSD comprises a socket, the socket comprises a base plate and a rectangular housing provided with anupper side face of the base plate; the base plate arranged at the internal portion of the rectangular housing is provided with a female terminal module, and the outer surface of the rectangular housing is provided with two mutually corresponding ear-shaped guide rails and inverted grips; the structure of the mini MSD comprises also a plug, the plug comprises a plug housing a male terminal module installed in the plug housing and capable of being inserted into a female terminal and a handle sleeved at the outer surface of the plug housing, the handle is provided with a locking device latched orlocked with the inverted grips, the handle is further provided with a latching column clamped into the ear-shaped guide rails, and the plug is clamped into the ear-shaped guide rails through the latching column and is buckled and fixed with the inverted grips through the locking device. Through unique structure improvement, mini MSD is provided with the handle to drive plugging and insertion of the plug and the socket through small pushing force, so that the problem is avoided that current plugging and insertion force is too large, and the effects are achieved that the structure is compact, the structure is novel and the safety performance is good.

Description

technical field [0001] The present invention relates to a maintenance switch, more specifically to a manual mini MSD Background technique [0002] Manual maintenance switch, or MSD (Manual Service Disconnector), is a commonly used manual operation device in the high-voltage circuit of electric vehicles, high-voltage power distribution boxes (PDU) and other equipment. The danger of electric shock and the damage of electrical components caused by overload and short circuit need to install a manual maintenance switch on the main circuit of the equipment with high current. The manual maintenance switch plays the role of protecting the power supply in the equipment circuit. In case of emergency or battery maintenance and installation, the manual maintenance switch can be disconnected in time to cut off the current of the battery pack, effectively avoiding accidents caused by improper operation of the maintenance personnel. of electric shock. There are many types of manual MSDs ...
