Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. The following directions such as "axial direction", "above", "below", etc. are all for showing the structural position relationship more clearly, and are not limiting to the present invention. In the present invention, the terms "vertical", "horizontal" and "parallel" are defined as: including ± 10% of cases based on the standard definition. For example, vertical generally refers to an angle of 90 degrees relative to a reference line, but in the present invention, vertical refers to a situation within 80 to 100 degrees inclusive.

Referring to fig. 1 to 4, the housing of the sensor of the present embodiment includes a housing 1 and a connecting portion 2.

The housing 1 in this embodiment has a mounting hole 11, and both side walls of the mounting hole 11 form a limiting portion 12.

In this embodiment, the connecting portion 2 is disposed in the mounting hole 11, and at least two sides of the connecting portion 2 are matched with the limiting portion 12 to limit the rotation of the connecting portion 2 in the mounting hole 11. The connecting portion 2 may have a polygonal structure, and two sides of the polygonal structure correspond to the sidewalls of the two sides of the mounting hole 11, so that the connecting portion 2 is restricted from rotating in the mounting hole 11.

In this embodiment, the housing 1 has a first fixing hole 13, the first fixing hole 13 is communicated with the mounting hole 11, the connecting portion 2 has a second fixing hole 21, and the second fixing hole 21 is aligned with the first fixing hole 13. During the installation, the bolt can wear to establish first fixed orifices 13 to in the cooperation of second fixed orifices 21, at threaded connection's in-process, owing to restricted connecting portion 2's rotation, consequently, need not additionally to fix connecting portion 2, it is more convenient to operate.

The connecting portion 2 in this embodiment may be a nut.

In the present embodiment, a resistance portion 14 is disposed in the mounting hole 11, and the resistance portion 14 is engaged with at least one side surface of the connecting portion 2. The resistance part 14 is arranged to position the connecting part 2 in the mounting hole 11. In this embodiment, the connecting portion 2 can be accurately crimped to the fixing position (the first fixing hole 13 and the second fixing hole 21 are aligned) by the crimping device, and the position of the connecting portion 2 can not relatively move after the connecting portion is crimped in place due to the arrangement of the resistance portion 14, so that the connecting portion 2 is prevented from being dislocated or falling out of the mounting hole 11.

The shell 1 in the embodiment can be formed by injection molding alone, so that the process is simpler and the production efficiency is higher.

In this embodiment, the resistance portion 14 includes a rib 141, the rib 141 extends along the length direction of the mounting hole 11, and the rib 141 is disposed on one of the inner side surfaces of the mounting hole 11. When the connector 2 is pressed into the mounting hole 11, the connector 2 presses the rib 141 to deform the rib 141 and make the rib 141 form resistance to the connector 2. The resistance part 14 adopts the form of the convex rib 141, has simpler structure and is easy to form, and can realize the fixation of the connecting part 2 and prevent the connecting part 2 from loosening or falling out.

In some embodiments, the resistive portion 14 may include a rough surface.

In this embodiment, the mounting hole 11 includes a first sidewall 111 and a second sidewall 112, two sides of the connecting portion 2 in the thickness direction respectively correspond to the first sidewall 111 and the second sidewall 112, and the rib 141 is disposed on an inner surface of the first sidewall 111.

In this embodiment, the distance between the rib 141 and the inner surface of the second sidewall 112 is smaller than the thickness of the connecting portion 2. So that the connecting portion 2 forms an interference fit in the mounting hole 11 to limit the looseness of the connecting portion 2.

In this embodiment, two ribs 141 are provided. In some embodiments, the rib 141 can be provided in a plurality of pieces (more than two pieces). In some embodiments, the ribs 141 can be disposed on both the first side wall 111 and the second side wall 112.

In this embodiment, the hardness of the connecting portion 2 is greater than that of the rib 141. Specifically, the connecting portion 2 is made of a metal material, such as iron or an iron alloy. The rib 141 (the housing 1) is integrally formed of a plastic material. In some embodiments, the rib 141 may be provided in the mounting hole 11 as a separate component.

In this embodiment, the thickness of the rib 141 decreases in a direction approaching the second sidewall 112. So that the rib 141 is more easily deformed when being stressed to prevent the rib 141 from being damaged when the connection part 2 is pressed in.

In this embodiment, the first fixing hole 13 is disposed on the second sidewall 112, and the first sidewall 111 is disposed with a groove portion 1111, where the groove portion 1111 corresponds to the first fixing hole 13. The arrangement of slot portion 1111, the application of reducible material saves material cost, and in addition, slot portion 1111 can form the position of keeping away to the bolt, and one end of bolt can go deep into slot portion 1111 or pass slot portion 1111 to, in this way, can adapt to the bolt of different length specifications.

In this embodiment, the groove portion 1111 is open at one side in the longitudinal direction of the mounting hole 11.

The above description in this specification is merely illustrative of the present invention. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
