It should be understood that the following description is only exemplary of the present invention, and is not intended to limit the present invention in any way.

An embodiment of the first aspect of the present invention provides an alarm device, as shown in fig. 1 to 6, the alarm device including: the alarm device comprises an alarm device body 100, a wire harness 200, a conductive connecting piece 300 and a protective connecting seat 400.

The wire harness 200 is connected to the alarm device body 100. One end of the conductive connector 300 is connected to the wire harness 200, and the other end of the conductive connector 300 is used to connect to the conductive contact 501 outside the cab. The warning device body 100 is connected to the cab 500 through the protective joint socket 400. And the wire harness 200, the conductive connector 300 and the conductive contact 501 outside the cab are all located inside the shield connector socket 400.

In one embodiment of the present invention, the conductive connector 300 includes a connector body 301, a first conductive contact 302, and a second conductive contact 303.

The first conductive contact 302 and the second conductive contact 303 are respectively disposed on the upper and lower sides of the connecting body 301. The first conductive contact 302 and the second conductive contact 303 communicate with each other. The first conductive contact 302 is connected with the wire harness 200. The second conductive contact 303 is for connection with the cab outside conductive contact 501.

For example, as shown in fig. 7 to 9, the connecting body 301 has a top-open type cylinder structure. The first conductive contact 302 is located on the inside of the bottom of the barrel. The second conductive contact 303 is located on the outside of the bottom of the can. For example, the bottom of the cylinder is a conductive plate. The first conductive contact 302 and the second conductive contact 303 are both conductive bodies, and are connected to each other through a conductive plate. Thereby, electrical conduction can be performed between the second conductive contact 303 and the first conductive contact 302.

The cab outer conductive contact 501 is a conductive body, and the power supply harness inside the cab 500 is electrically connected to the cab outer conductive contact 501. This enables electrical conduction between the power supply inside the cab 500 and the cab outside conductive contact 501.

A locking pin is inserted between the locking hole 702 and the locking matching hole 703 to lock and connect the first connecting cylinder 401 and the second connecting cylinder 402.

For example, as shown in fig. 2 and 4-6, the locking hole 702 on the first connecting cylinder 401 mates with the locking mating hole 703 on the second connecting cylinder 402. When the first connecting cylinder 401 is completely screwed into the inner side of the second connecting cylinder, the locking hole 702 is aligned with the locking mating hole 703, and a locking pin is inserted between the locking hole 702 and the locking mating hole 703. This can prevent the first connecting cylinder 401 and the second connecting cylinder 402 from loosening. When the alarm device body 100 needs to be disassembled or repaired, the locking pin is disassembled first, and then the first connecting cylinder 401 is screwed out from the inner side of the second connecting cylinder 402.

According to the above-described embodiments, the locking pin is inserted between the first connecting cylinder 401 and the second connecting cylinder 402, so that the connection reliability between the first connecting cylinder 401 and the second connecting cylinder 402 can be improved, and the connection stability between the warning device body 100 and the cab 500 can be improved.
