[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0021] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0022] like Figures 1 to 4As shown, a round cap jump sensor includes a sensor body 1, one end of which is provided with a terminal 13, and the terminal 13 is connected to one end of a wire 14. The end face of the sensor body 1 away from the terminal 13 is the part where the internal bimetallic strip exchanges heat with the outside world, and the end face is provided with a reinforcing rib 11. The reinforcing rib 11 is used to strengthen the deformation resistance of the end face of the sensor body 1 to prevent the deformation of the end face from affecting the heating effect of the sensor. The sensor body 1 is provided with a connecting piece 12, and the sensor body 1 is fixedly connected to other components through the connecting piece 12.

[0023] One end of the sensor body 1 close to the terminal 13 is located inside the detachably connected sealing cover 2, and the other end of the wire 14 passes through the sealing cover 2. The sealing cover 2 is provided with a wire tube 21 that matches the wire 14, and a detachable pipe plug 212 is provided inside the wire tube 21. The wire 14 is interference-fitted with the wire tube 21 through the pipe plug 212. The pipe plug 212 fills the gap between the wire 14 and the wire tube 21, thereby improving the sealing of the assembly of the wire 14 and the wire tube 21. A groove 211 that matches the pipe plug 212 is provided on the inner top surface of the sealing cover 2 at a position corresponding to the wire tube 21, and one end of the pipe plug 212 extends into the wire tube 21, and the other end is embedded in the groove 211. The detachable pipe plug 212 is easy to replace.

[0024] A step 15 is provided on one side of the sensor body 1 close to the terminal 13, an external thread 151 is provided on the side of the step 15, and an internal thread matching the external thread 151 is provided on the inner wall of the sealing cover 2. The threaded sealing cover 2 is easy to install and disassemble, and the outer wall of the sealing cover 2 is provided with an anti-slip pattern 24, which is used to facilitate the rotation of the sealing cover 2. A gasket 3 is provided on the top surface of the step 15, and a plurality of positioning pins 32 are evenly spaced in the circumferential direction of the gasket 3. The step 15 is provided with a positioning hole 152 matching the positioning pin 32, and a convex ring 23 matching the gasket 3 is provided on the inner wall of the sealing cover 2. The gasket 3 improves the sealing performance of the sealing cover 2 and the sensor body 1, and the detachable gasket 3 is easy to replace. A chamfer 31 is provided on one side of the gasket 3 close to the convex ring 23, and the convex ring 23 fits the inclined surface formed by the chamfer 31 on the gasket 3. The chamfer 31 increases the contact area between the gasket 3 and the convex ring 23, thereby improving the sealing performance. The sealing cover 2 is provided with a glue injection port 22, and the glue injection port 22 is provided with a top cover 221. The top of the glue injection port 22 is threadedly connected to the top cover 221, and the detachable top cover 221 is convenient for freely opening and closing the glue injection port 22. Opening the top cover 221 to inject the potting glue; closing the top cover 221 can prevent dust and impurities from falling into the interior of the sealing cover 2.

[0025] The sealing cover 2 isolates the end of the sensor body 1 provided with the terminal 13 from the outside, and fills the space between the sealing cover 2 and the sensor body 1 with potting glue through the potting port 22, so that the sensor body 1 has good waterproof performance.

[0026] The working principle of the specific implementation of the utility model is as follows: the sealing cover 2 is screwed into the sensor body 1, so that one end of the sensor body 1 with the terminal 13 is isolated from the outside world, one end of the wire 14 is connected to the terminal 13, and the other end passes through the wire tube 21 to connect to the external circuit. The sealing glue is injected into the space between the sealing cover 2 and the sensor body 1 through the glue injection port 22 to improve the overall waterproof performance of the sensor.
