As shown in fig. 1 to 3, the present invention provides a protection system for installation protection of a BMS board 4, including a protection member, a detection member 2, a control member 3, and a socket; the protection part is arranged at one side of the BMS board 4 where the capacitor 401 is arranged, and the protection part is provided with an alignment part 101 so that the capacitor 401 can be inserted into the alignment part 101; the detector 2 is disposed on the guard, and the detector 2 can detect that the capacitor 401 is inserted into the positioning portion 101; the detection part 2 is in communication connection with the control part 3, and the control part 3 is in communication connection with the socket so as to control the socket to be powered on or powered off.

the utility model provides a protection system, through the protection piece set up in BMS board 4 can protect BMS board 4 towards one side of electric capacity 401, and through the counterpoint portion 101 that forms on the protection piece, can make electric capacity 401 get into in counterpoint portion 101 to by the detection piece 2 on the protection piece detect, and then can be to control 3 signals, make control 3 control socket circular telegram, realize circular telegram and outage of criticizing the electricity.

In use, the protection element is arranged on the BMS board 4 through the positioning part 101, and when the capacitor 401 enters the positioning part 101, the protection element can be detected by the detection element 2, so that a signal can be sent to the control element 3, the socket is controlled to be electrified, and the electric screwdriver used for installation can work.

When the worker does not attach the protection component during working, the detection component 2 cannot detect the capacitor 401, and therefore the control component 3 cannot receive the detection signal of the detection component 2, so that the socket cannot be powered on, and the electric screwdriver cannot be used.

It should be added that in the present application, the detecting element 2 and the protecting element are detachably connected, and the detecting element 2 is formed with a connecting hole and connected with the protecting element by a fastening element.

As shown in fig. 1 to 3, the shape of the bit part 101 matches the shape of the capacitor 401, and is a rectangular groove; the rectangular groove penetrates the guard in the thickness direction of the guard.

The capacitor 401 on the BMS board 4 in this application is rectangular, and therefore the positioning portion 101 in this application is rectangular shaped to match the shape of the capacitor 401. The capacitor 401 and the positioning portion 101 having the matched shapes can stabilize the guard after installation.

Since the detecting member 2 in the present application is disposed on the side of the protection member facing away from the BMS board 4, by making the rectangular groove penetrate the protection member in the thickness direction thereof, the capacitor 401 can protrude from the plane of the protection member after the protection member is mounted on the BMS board 4, and thus can be detected by the detecting member 2.

It should be noted that the reason why the alignment portion 101 is rectangular in the present application is to better match the shape of the capacitor 401, and if the capacitor 401 has another form such as a cylinder, the shape of the alignment portion 101 is adapted to the capacitor 401 having another form.

On the other hand, if the installed BMS board 4 has the drawn mark, it is proved that the worker uses the hood shield 1 when installing, and if the drawn mark does not appear on the plug 402, it is proved that the hood shield 1 is not used, thereby emphasizing the quality inspection of the BMS board 4.

It should be added here that, since the plug 402 on the BMS board 4 is relatively rigid, the extension 102 and the indication part 103 on the extension 102 in the present application are formed to correspond to the position of the plug 402 for easy marking.

The extension 102 may cover two connectors 402, but preferably, the extension 102 is disposed at a position corresponding to one connector 402, so that the connectors 402 can be easily distinguished.

Preferably, the indicator 103 is lightning-like, as shown in fig. 1 in conjunction with fig. 2.

The mark portion 103 in this application is the lightning and can make the operation personnel be difficult for directly drawing through the mark, and on the other hand can match the structure that is used for battery safety installation that this application corresponds.
