One of the edges 221 is integrally formed with the first casing 21, which is advantageous in that the first casing 21 and the second casing are assembled together by only locking and fixing the two stacked edges 221, thereby facilitating the assembly.

Referring to fig. 1 and 2, in an embodiment, external thread groups 212 are further disposed between the two slot groups 211, and the external thread groups 212 and the slot groups 211 on two sides thereof are spaced apart from each other, so that the external thread groups 212 and the slot groups 211 can be manufactured separately. The external thread group 212 specifically includes a plurality of external threads 2120 arranged along the axial direction of the first housing 21. It will be understood herein that the external threads 2120 are not in the form of a full turn, but rather are generally along a portion of the circumference of the first housing 21.

The different structures of the slot set 211 and the external thread set 212 determine that the fixed structures of the slot set 211 and the external thread set 212 are different. In practical use, one of the card slot group 211 and the external thread group 212 can be selected for installation. Meanwhile, the sensor 100 provided with the slot group 211 and the external thread group 212 has more mounting modes and wider application range.

In an embodiment, the external thread set 212 may be disposed on the basis of the non-slot set 211, and therefore, the present invention further provides a sensor 100, wherein the external thread set 212 is disposed on two opposite sides of the outer peripheral surface of the first housing 21, and other features are the same as those of the above embodiment, and thus are not repeated.

Based on the sensor 100 with the new structure of the first housing 21 described in the above embodiments, the present invention further provides a sensor assembly 200, which includes the sensor 100 and the clamping members 5 and 5 'described in the above embodiments, please refer to fig. 3 to 12, wherein the clamping members 5 and 5' include the annular body 51 with the notch, two opposite engaging portions 510 are provided on the inner side surface of the annular body 51, and the two engaging portions 510 are correspondingly clamped into the two opposite engaging slots 2110. The clamping means 5, 5' are here the above-mentioned fastening structures. Through the connection between chucking piece 5, 5 'and sensor 100, further can install sensor 100 in required position, such as wall or ceiling etc. through this chucking piece 5, 5', need not to rely on gluing or the fixed mode of spring, simple structure, dismouting are more swift, are convenient for the maintenance of sensor 100 and sensor body 1.

Referring to fig. 3 to 8, the connection between the first clamping member 5 and the clamping groove set 211 is described first.

In particular, the clip 5 is used to mount the sensor 100 in a mounting hole 30 in the form of a through hole. As shown in fig. 5 and 8, the second housing 22 is located on one side of the mounting plate 3, and the clamping member 5 is located on the other side of the mounting plate 3, and since the second housing 22 and the clamping member 5 are both sized to be larger than the inner diameter of the mounting hole 30, neither the second housing 22 nor the clamping member 5 can enter the mounting hole 30. The mounting effect of this form of retainer 5 on a hard mounting plate is superior to that on a soft mounting plate.

Referring to fig. 3 and 6, in one embodiment, the annular body 51 is in an "Ω" shape, that is, two free ends of the annular body 51 are bent outwards to form two catches 513. This has the advantage that the locking legs 513 allow the annular body 51 to be larger in size, thereby preventing the annular body 51 from passing entirely through the mounting hole 30, and thus allowing for a wider range of inner diameters of the mounting hole 30, as shown in fig. 5 and 8.

Since the slots 2110 are arranged along the axial direction of the first housing 21, the engaging portions 510 are selected to enter the corresponding slots 2110 according to the height of the mounting hole 30 so as to be adapted to the thickness of the mounting plate 3, thereby preventing a gap from being generated between the ring body 51 and the mounting plate 3, as shown in fig. 5 and 8.

In one embodiment, the engaging portion 510 is formed at a non-axial center position on the inner side surface of the annular body 51, so that the distance from the engaging portion 510 to the upper surface 511 and the lower surface 512 of the annular body 51 are different. This has the advantage that the clamping member 5 can be positioned with its upper surface 511 close to the mounting hole 30 and also with its lower surface 512 close to the mounting hole 30, so that when the clamping portion 510 is clamped in the same clamping groove 2110, it will be adapted to mounting holes 30 of different heights and thus mounting plates 3 of different thicknesses. In a preferred embodiment, the engaging portion 510 is flush with the upper surface 511 of the ring body 51, or flush with the lower surface 512, as shown in fig. 3, so as to facilitate the manufacturing of the ring body 51 and the engaging portion 510 thereof.

When assembling the sensor assembly 200, the first housing 21 of the sensor 100 is first inserted through the mounting hole 30, and then the retainer 5 is pushed from the side of the portion of the first housing 21 protruding from the mounting hole 30 on the other side of the mounting plate 3, so that the engaging portion 510 thereof enters the engaging groove 2110 (the straight arrow in fig. 3 and 6 indicates the mounting direction, the same applies below).

With reference to fig. 9 to 12, the connection between the clip 5' and the housing 2 in another configuration is then described.

In one embodiment, the retainer 5 ' further comprises two resilient tabs 52, 52 ' connected to the annular body 51 and extending in the axial direction of the first housing 21, as shown in fig. 9 and 10, the resilient tabs 52, 52 ' being capable of being elastically deformed in the radial direction of the first housing 21. Thus, after the ring 51 and the engaging groove 2110 are engaged with each other, the sensor 100 can be mounted in the mounting hole 30 by providing a pressing force by elastic deformation of the elastic pieces 52 and 52'. The clamping part 5' is suitable for mounting holes 30 in the form of through-holes or blind holes, and is particularly suitable for mounting holes 30 having a large height.

Referring to fig. 9, in one embodiment, the two elastic pieces 52 are disposed in a trumpet shape, and the distance between the two elastic pieces 52 gradually increases as the distance from the ring body 51 increases.

Alternatively, referring to fig. 10, in an embodiment, the resilient sheet 52' includes a first sub-resilient sheet 521 connected to the annular body 51 and a second sub-resilient sheet 52 connected to the first sub-resilient sheet 521, and the first sub-resilient sheet 521 is connected to the second sub-resilient sheet 52 in a bending manner, so that the resilient force is provided at a position where the first sub-resilient sheet 521 is connected to the second sub-resilient sheet 52 in a bending manner. The bent connection between the first sub-spring plate 521 and the second sub-spring plate 52 may protrude outward or may be recessed inward. Specifically, in the present embodiment, the bent connection portion of the first sub-elastic piece 521 and the second sub-elastic piece 52 protrudes outward, as shown in fig. 10.

Further, in one embodiment, since the ring body 51 only needs to be fitted with the catching groove 2110, it may not need to be fitted with the mounting hole 30, and in order to ensure no gap between the second housing 22 and the opening of the mounting hole 30, the ring body 51 may have a "C" shape, and both free ends thereof may not protrude, and thus may completely enter the mounting hole 30, as shown in fig. 11 and 12, whereby the external aesthetic property of the installation of the sensor assembly 200 may be ensured.

When assembling the sensor assembly 200, it is necessary to assemble the retainer 5 'with the sensor 100, and then compress the two resilient pieces 52, 52' inward to be integrally installed in the installation hole 30, as shown in fig. 11.

Referring to fig. 13-15, the present invention further provides a sensor assembly 200, which includes the sensor 100 with the external thread set 212 and the thread ring 6, and the thread ring 6 is connected to the external thread set 212.

Specifically, the thread ring 6 has a ring shape, and an inner annular surface thereof is provided with an internal thread 610 engaged with the external thread 2120. This turn 6 is also suitable for mounting holes 30 in the form of through holes, which are located on both sides of the mounting plate 3 with the second housing 22, respectively, and has a good fixing effect on both hard and soft mounting plates.

In assembling the sensor assembly 200, the first housing 21 of the sensor 100 is first inserted through the mounting hole 30, and then the threaded ring 6 is screwed onto the first housing 21 on the other side of the mounting plate 3 until it is pressed against the other side of the mounting hole 30.

Referring to fig. 13 and 14, in one embodiment, the internal threads 610 are not arranged in a complete circle in the circumferential direction, but are arranged at intervals to form a plurality of internal thread groups 61 to adapt to the shape of the external thread groups 212, and a concave recess 62 is formed between two internal thread groups 61 arranged at intervals. This has the advantage of facilitating the manufacture of the screw ring 6 and the internal thread 610 thereof, and the recess 62 allows the trace to pass through when the screw ring 6 is mounted on the first housing 21, thereby facilitating the trace design of the sensor body 1 and the mounting of the sensor 100.

It is understood that the sensor assembly 200 provided by the present invention may also include both the threaded ring 6 and the clamping members 5, 5 'to be present as a complete, more adaptable product, wherein the threaded ring 6 or the clamping members 5, 5' are selected for use according to the form of the specific mounting plate 3 and the mounting hole 30. Therefore, the present invention also provides a sensor assembly, which includes the sensor 100 having the external thread group 212 and the slot group 211, the thread ring 6, and the clamping member 5, 5' having the same features, and therefore, the description thereof is omitted.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
