Embodiment

[0039] Please refer to figure 1 A schematic structural diagram of a manual maintenance switch 100 according to an embodiment of the present invention is shown. The manual maintenance switch 100 mainly includes a socket 20 and a plug 10 detachably connected to the socket 20 . In addition, the manual maintenance switch 100 also includes: a fuse with pin assembly 30 arranged in the plug 10 and two pins 40 for high current transmission, such as figure 2 shown. A fuse can be fixed between the two pins 40 for short-circuit protection, and the copper bar can also be directly connected to play the role of a switch. The socket 20 is provided with two jacks (not shown) that are mated with the pins 40, and the tails of the jacks need to be electrically connected to the outside. At the same time, the manual maintenance switch 100 of the embodiment of the present invention is also provided with a set of signal contact pairs for transmitting the signal of the connection status of the plug ...

Abstract

The invention discloses a manual maintenance switch and belongs to the technical field of electric passenger vehicles. The manual maintenance switch comprises a socket and a plug detachably connectedwith the socket. The plug comprises a first shell and a handle. One end of the handle is movably connected to the outer side wall of the first shell and the other end of the handle is respectively provided with a primary locking piece used for locking the handle to the first shell and a secondary locking piece used for locking the primary locking piece. The first locking piece is arranged on the inner side of the handle and is matched with a first locking groove arranged on the outer side wall of the first shell. The secondary locking piece is slidingly arranged on the handle The secondary locking piece comprises a spring bolt located on the inner side of the handle and a limiting plate connected with the spring bolt. The spring bolt is matched with a second locking groove arranged at theside of the primary locking piece. The limiting plate is in sliding connection with the primary locking piece. The manual maintenance switch is provided with a reliable locking mechanism and can be connected with the outside in three directions. The unlocking operation direction of the product is convenient to operate in a narrow space in the length direction of the product.

Description

technical field [0001] The invention relates to the technical field of electric passenger vehicles, in particular to a manual maintenance switch. Background technique [0002] Since there is no corresponding industry standard for manual maintenance switches for new energy electric passenger vehicles, most of the manual maintenance switches for passenger electric vehicles on the market do not have reliable primary locking and secondary locking mechanisms. The tail lock line can only be connected in one direction, and the unlocking is in the width direction of the product, which is not convenient for locking and unlocking in places with limited space. Contents of the invention [0003] The purpose of the present invention is to provide a manual maintenance switch to solve the problem of poor locking effect of the existing manual maintenance switch. [0004] The technical scheme that the present invention solves the problems of the technologies described above is as follows:...
