In order to avoid the problems of aging, breakage and the like of the conducting wire and further cause the condition that the ignition switch can not work due to abnormal setting in work, a wireless ignition switch without the conducting wire is also provided in the prior art, and the ignition switch usually adopts the matching of a movable contact and a fixed contact to realize the connection and disconnection of a circuit. For example, patent document No. CN215578328U discloses a contact type arc discharge ignition switch, which includes a rotor, a moving contact, and a lock base, wherein two sets of contacts are provided on the lock base, the moving contact is rotatably provided along with the rotor, and when the moving contact rotates to a proper position, the contact of the moving contact contacts the contact of the contact on the lock base to turn on the circuit.

However, the ignition switch in the technical scheme is lack of a waterproof structure, rainwater can easily enter the ignition switch in rainy days, short circuit occurs between the movable contact and the fixed contact, and the ignition switch cannot work.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the present invention is to provide an ignition switch plug-in unit with waterproof function, which is added with a waterproof structure to prevent rainwater from entering between the movable contact and the stationary contact, thereby avoiding short circuit; the elastic piece is arranged, so that the movable contact and the fixed contact are well contacted; the section of the guide post is in a central symmetry shape, so that misassembly of the movable contact piece can be avoided.

In order to achieve the above purpose, the utility model provides a following technical scheme: an ignition switch plug-in with waterproof function, including the moving contact assembly, plug-in components; the movable contact component comprises a rotor; the plug-in assembly comprises a main body and an inlay arranged in the main body; the rotor is rotatably arranged at one end of the inlay, a moving contact rotating along with the rotor is arranged at one end of the rotor facing the inlay, and a static contact is arranged on the end surface of the inlay facing the rotor; the movable contact is connected with the stationary contact in a detachable and abutting mode, and is characterized in that: and a waterproof structure is arranged between the rotor and the main body. Specifically, it may be further configured to: the waterproof structure comprises an annular baffle arranged at one end of the rotor, a waterproof space is arranged between the annular baffle and the end surface of the rotor facing the main body, the end face of the inlay facing the rotor extends for a distance towards the direction close to the rotor and then forms a step with the main body, and the movable contact and the step are arranged in the waterproof space.

By adopting the technical scheme, the waterproof structure is arranged between the rotor and the main body, so that rainwater can be prevented from entering between the movable contact and the fixed contact. The waterproof structure comprises an annular baffle and a step, wherein a waterproof space is arranged between the annular baffle on the rotor and the end face of the rotor (the annular baffle can extend for a distance towards the direction close to the inlay, and at the moment, the annular baffle and the end face of the rotor can naturally enclose the waterproof space), the step is formed by extending for a distance towards the end face far away from the main body from the end face of the inlay facing the rotor, a static contact is arranged on the end face of the inlay facing the rotor, at the moment, the height difference exists between the inlay and the main body, and the step extends into the waterproof space, namely, the annular baffle surrounds the periphery of the step, so that the static contact is also positioned in the waterproof space; the movable contact is originally arranged in the waterproof space, so far, the movable contact and the fixed contact are both positioned in the waterproof space at the moment, the movable contact and the fixed contact are protected by the annular baffle and the rotor, rainwater is blocked by the annular baffle and the rotor and cannot directly enter between the movable contact and the fixed contact, the rainwater naturally flows away when falling to the main body and cannot enter the waterproof space through the step, and therefore the set waterproof structure is good in waterproof effect, and the phenomenon of short circuit between the movable contact and the fixed contact can be effectively avoided.

To the connection between the sound contact, wherein, because the rotor is the rotatable one end that sets up in the inlay, the movable contact sets up in the one end of rotor towards the inlay, the stationary contact sets up on the terminal surface of inlay towards the rotor, and the movable contact is to dismantle the conflict with the stationary contact and be connected, means when the rotor rotates to the exact position, the movable contact can switch on the circuit with the stationary contact butt, and when the rotor rotated the exact position, the conflict between movable contact and the stationary contact is connected and is dismantled, does not switch on the circuit promptly, the control of being convenient for.
