[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0032] As Figures 1-9The utility model discloses a signal sensor, including sensor head 1, the connector 2 of sensor head 1 front side and the connecting wire 3 between connector 2 and sensor head 1, after the signal sensor is installed to the pipeline position of need monitoring, the sensitive element in sensor head 1 at this time can convert physical signal into electric signal through circuit board (not marked in the drawing) and then pass through connecting wire 3 and give connector 2, and because connector 2 can be electrically connected with control system or other equipment, therefore electric signal can pass through connector 2 and give control system and other equipment (this is prior art, not do specific elaboration here), the connector 2 is installed with connecting plug 21, still including dust cover 4 that sets up on connector 2, the shell 5 includes front connecting section 52 and rear connecting section 53, the projection of connecting plug 21 towards the front side is located on dust cover 4, dust cover 4 and connector 2 are detachably connected, 1. because dust cover 4 is located on connector 2 and the projection of connecting plug 21 towards the front side falls on dust cover 4, therefore installs dust cover 4 on connector 2 after, can effectively prevent dust and other pollutants from entering the inside of connector 2 to avoid the interface of connecting plug 21 and control system when subsequent enablement signal sensor appears contact failure, short circuit etc. problem, 2. because dust cover 4 can be detachably connected with connector 2, therefore before enabling signal sensor, dust cover 4 can be detached from connector 2 and normally used signal sensor, and when signal sensor is detached from the vehicle or is not enabled signal sensor is in storage and accomodation state, dust cover 4 can play the dustproof effect at this time.

[0033] Among them, the dust cover 4 is made of rubber and other materials that can easily deform, the connecting plug 21 includes a shell 5 and an insertion portion 211, the insertion portion 211 is located inside the shell 5, the shell 5 has an upper positioning plug 51 protruding upward, the dust cover 4 has an upper positioning slot 41 corresponding to the upper positioning plug 51, 1. Because the dust cover 4 can easily deform and can more smoothly force the dust cover 4 to pass through the upper positioning slot 41, the upper positioning plug 51 is located in the upper positioning slot 41, and the dust cover 4 is located around the connecting plug 21; 2. Because of the existence of the upper positioning plug 51 in the shell 5, after the dust cover 4 is set around the connecting plug 21, the dust cover 4 cannot rotate and move forward and backward compared to the connecting plug 21 because the upper positioning plug 51 is located in the corresponding upper positioning slot 41, so the relative position of the dust cover 4 and the connecting plug 21 is determined.

[0034] Preferably, the insertion part 211 is located in the front connecting section 52, the width of the front connecting section 52 is greater than that of the rear connecting section 53, the upper positioning plug 51 is located between the front connecting section 52 and the rear connecting section 53 and is fixedly connected with the shell 5. 1. Since the width of the front connecting section 52 is greater than that of the rear connecting section 53, after the dust cover 4 is sleeved on the shell 5, the part of the dust cover 4 located on the rear connecting section 53 with a smaller width than the front connecting section 52 is difficult to pass over the front connecting section 52 without external force, thereby further improving the connection stability of the dust cover 4 and the shell 5.

[0035] Preferably, the upper positioning plug 51 is in the shape of a triangular prism, and the upper positioning plug 51 comprises a front guide surface 511 which is inclined upward from front to back. Since the front guide surface 511 of the upper positioning plug 51 is inclined upward from front to back, the upper positioning plug 51 is in the shape of a triangular prism with a narrow top and a wide bottom. When the dust cover 4 is mounted on the shell 5, the top of the upper positioning plug 51 enters the upper positioning slot 41 first. The inclined guide surface 511 makes the upper positioning plug 51 more smoothly aligned with the upper positioning slot 41. After the dust cover 4 is assembled with the shell 5, the part of the dust cover 4 located in front of the upper positioning plug 51 is limited by the upper positioning plug 51 and cannot move backward, and the part of the dust cover 4 located behind the upper positioning plug 51 is also limited by the upper positioning plug 51 and cannot move forward, thereby making the upper positioning plug 51 and the upper positioning slot 41 stably connected together without external force.

[0036] The bottom of the rear connecting section 53 protrudes downward and is provided with a plurality of limiting ribs 531, the dust cover 4 is provided with a lower positioning slot 42 corresponding to each limiting rib 531, and the dust cover 4 is integrally provided with a cooperation plate 43 between adjacent lower positioning slots 42, and the cooperation plate 43 is provided with a pull ring 431 downward. 1. When the dust cover 4 is mounted on the shell 5, the dust cover 4 deforms and forcibly passes over the limiting ribs 531 at the bottom of the rear connecting section 53, thereby falling into the corresponding lower positioning slot 42, and the cooperation of the limiting ribs 531 and the lower positioning slot 42 further improves the stability of the dust cover 4 on the shell 5; 2. When the dust cover 4 needs to be removed from the shell 5, compared to applying force to the periphery of the dust cover 4 to deform it, applying force to the pull ring 431 can more smoothly deform the bottom of the dust cover 4, thereby facilitating the separation of the dust cover 4 and the shell 5.

[0037] Preferably, the pull ring 431 is arranged in a semi-circular shape with the opening facing upwards, and the pull ring 431 is hollow inside and is provided with a plurality of contact protrusions 4311. The hollow design of the pull ring 431 reduces the overall weight of the pull ring 431, and the contact protrusions 4311 inside increase the roughness of the inner wall surface of the pull ring 431, further enhancing the friction between the hand and the pull ring 431, facilitating force exertion.

[0038] Preferably, each of the contact protrusions 4311 is arranged in an arc shape with the opening facing downwards. The arc design is not only beautiful, but also provides a better support point when the finger is inserted into the pull ring 431 and exerts pressure on the pull ring 431, preventing slipping and further facilitating force exertion.

[0039] In addition, the connector 2 is made of a material that is easy to deform and includes a connecting groove 22 for accommodating the connecting plug 21, the connecting groove 22 is arranged in a flared shape from front to back, the connecting plug 21 includes a limiting plug 212 at the rear side, the limiting plug 212 is arranged in a tapered shape from front to back, the front side end face of the limiting plug 212 abuts against the connector 2, therefore, during the process of accommodating the connecting plug 21 into the connecting groove 22, the connector 2 can be deformed to forcibly accommodate the front side of the limiting plug 212 into the connecting groove 22, at this time, since the front side of the limiting plug 212 abuts against the connector 2, it provides convenience for accommodating the connecting plug 21 into the connector 2 and further realizing the fixation of the connecting plug 21 and the connector 2.

[0040] The above description of disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application should not be limited to the embodiments shown herein, but should be consistent with the widest scope consistent with the principles and novel features disclosed herein.
