Description

Technical Field

[0001] This utility model relates to the field of sensors, and in particular to a sensor with a protective wire-pressing structure. Background Technology

[0002] With the development of IoT technology, the demand for environmental detection, especially human presence detection, is becoming increasingly widespread in artificial intelligence, smart homes, and smart security technologies. Consequently, various sensors are widely used. Furthermore, with industry development, stringent safety certification requirements have been established for sensors. Safety certification, or safety specification certification, is a comprehensive set of regulations aimed at ensuring personal safety, property safety, and environmental protection. Through this certification, electronic products must undergo rigorous testing before being released to the market to ensure they comply with relevant safety standards during design, production, sales, and use, effectively preventing harm or loss to users and the surrounding environment. Safety specifications cover many aspects, such as prevention of electric shock, fire prevention, and protection against mechanical and thermal injuries. To ensure the stability and safety of power cords under various operating conditions, safety specifications require multiple tensile tests on power cords, with corresponding requirements for power cord displacement and wire tension during the tensile tests. Products must meet these requirements to obtain safety specification certification. In addition, safety regulations require that wiring terminals not be exposed and must be properly protected.

[0003] To meet relevant safety regulations, many products have also been designed accordingly, for reference. Figure 1 The illustration shows the structure of a sensor disclosed in Chinese Utility Model Patent No. CN 219284316 U. In order to limit the power cord, the sensor is provided with a wire clamping structure 122, which is fixed by screws. In order to protect the wiring part, the sensor is also provided with a protective cover 17 that is flipped and connected to the end of the fixing structure 121 of the upper shell 15. By flipping and connecting the protective cover 17 and the upper shell 15, the fixing structure 121 can be exposed to facilitate the wiring operation of the cable 30. After the wiring is completed, the protective cover 17 is closed on the upper shell 15 to protect the cable 30.

[0004] However, existing protective structures are complex. During installation, operators need to remove various components. For example, for the sensor disclosed in the aforementioned patent, the wire clamping structure 122 needs to be removed before wiring, and then screwed back on after wiring. Currently, the cost of using the sensor is primarily the electrician's labor cost rather than the price of the equipment itself. This is especially true in the European market, where electricians are a specialized trade with specific entry barriers. Electrical equipment requires professional electricians from procurement to installation, and their fees are calculated by the hour. As mentioned above, the complex protective structures of existing equipment require electricians to spend considerable time on installation, making it difficult to shorten installation time, reduce labor costs, and ultimately result in high operating costs for the corresponding equipment.

[0005] Further reference Figure 2A and Figure 2B As shown, a surface-mounted infrared sensor 10P is illustrated. The infrared sensor 10P includes a main body 11P and a back cover 12P covering the main body 11P. The back cover 12P extends from top to bottom over the back of the main body 11P, thus covering the wiring portion on the back of the main body 11P, providing a certain degree of protection and improving the aesthetics of the infrared sensor 10P, making it suitable for surface mounting. The back cover 12P has a simple structure and is easy to install onto the main body 11P. However, the back cover 12P cannot restrict the corresponding power cord. Furthermore, during installation, the operator must complete the wiring operation with the back cover 12P separated from the main body 11P before covering the main body 11P with the back cover 12P. Because the back cover 12P covers the main body 11P from top to bottom, the operator needs to properly position the power cord to avoid obstructing the back cover 12P during operation, making operation inconvenient. (Reference) Figure 2C The existing microwave sensor 20P also adopts a design in which the main body 21P is covered by the back shell 22P. However, as mentioned above, this design cannot meet the requirements for limiting the power cord and is also inconvenient to operate. Utility Model Content

[0055] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0056] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0057] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0058] Refer to the accompanying drawings in the specification of this utility model. Figures 3 to 7 A sensor 100 with a protective wire-pressing structure according to an embodiment of the present invention is illustrated. The sensor 100 with the protective wire-pressing structure includes a sensor body 10 and a protective wire-pressing housing 20. With the detection direction of the sensor body 10 as the forward direction, the sensor body 10 has a wiring portion 11 located at its rear end. The protective wire-pressing housing 20 is covered on the rear end of the sensor body 10 and has a rearward wire outlet 30. The cable correspondingly connected to the wiring portion 11 can be led out from the protective wire-pressing housing 20 through the rearward wire outlet 30, thereby forming protection for the wiring portion 11 and meeting the corresponding safety requirements.

[0059] Furthermore, the protective wire clamping housing 20 includes a protective base 21 and a side-rotating protective cover 22 pivotally mounted on the protective base 21 to open or close the protective wire clamping housing 20 based on the pivoting of the side-rotating protective cover 22. The side-rotating protective cover 22 has a lateral opening direction that flips toward the side of the sensor 100 with the protective wire clamping structure, thereby facilitating the operator to perform wiring operations without disassembling the protective wire clamping housing 20, and facilitating the cable lead-out based on the pivoting opening of the side-rotating protective cover 22.

[0060] It is worth mentioning that the side-turn protective cover 22 is pivotally mounted on the protective base 21 and has a lateral opening direction. That is, the side-turn protective cover 22 is flipped toward the side of the sensor 100 with the protective wire pressing structure, thereby exposing the wiring part 11. After the wiring is completed, the side-turn protective cover 22 can be flipped and closed without affecting the cable, which is convenient for the operator to operate.

[0061] Furthermore, the protective cable clamping housing 20 includes a cable clamping seat 23 disposed on the protective base 21 and a side-rotating cable clamping clip 24 pivotally mounted on the cable clamping seat 23. The cable clamping seat 23 and the side-rotating cable clamping clip 24 have matching structures so that, when the side-rotating cable clamping clip 21 is inserted into the cable clamping seat 23, the corresponding cable can be clamped between the side-rotating cable clamping clip 24 and the cable clamping seat 23. The side-rotating cable clamping clip 24 is rotatably mounted on the cable clamping seat 23, thereby avoiding the risk of the side-rotating cable clamping clip 24 detaching from the cable clamping seat 23 and being lost, and also effectively reducing the labor cost during installation.

[0062] It is worth mentioning that the cable is fixed by the side-turn wire clamp 24 and the wire clamp seat 23, which forms a limit on the cable. The wire clamp seat 23 has a size that matches the wiring part 11. The outgoing and incoming wires of the sensor 100 with the protective wire clamp structure can be fixed by the side-turn wire clamp 24 and the wire clamp seat 23.

[0063] Specifically, the side-turning wire clamp 24 is pivotally mounted on the wire clamping base 23 and has a lateral opening direction, that is, the side-turning wire clamp 24 flips towards the side of the sensor 100 with the protective wire clamping structure, so that after the operator completes the wiring, the corresponding cable can be arranged towards the rear. After the side-turning wire clamp 24 is inserted into the wire clamping base 23, the side-turning protective cover 22 can be flipped and closed without affecting the cable, so that the cable is led out from the rear outlet 30.

[0064] It is worth mentioning that the protective seat 21 and the side-turn protective cover 22 form protection for the wiring part 11, the wire clamp 23 and the side-turn wire clamp 24. Specifically, when the side-turn protective cover 22 is closed, a protective cavity is formed between the side-turn protective cover 22 and the protective seat 21 to accommodate the wiring part 11, the wire clamp 23 and the side-turn wire clamp 24, thereby protecting the wiring part 11, the wire clamp 23 and the side-turn wire clamp 24. The top-outlet buckle 30 is connected to the protective cavity so that the cable is led out from the protective cavity from the rear-outlet port 30.

[0065] Preferably, in this structure of the present invention, the side-turn protective cover 22 and the side-turn wire clamp 24 have opposite lateral opening directions, which can avoid mutual obstruction and help to expand the pivot angle of the side-turn protective cover 22 and the side-turn wire clamp 24, so as to avoid affecting the wiring operation and thus ensure that the wiring operation is not affected without disassembling the accessories.

[0066] Preferably, refer to Figure 7 As shown, the viewpoint is a top view of the rear end of the sensor 100 with the protective wire clamping structure. The opening direction of the side-turn protective cover 22 is clockwise, and the opening direction of the side-turn wire clamping buckle 24 is counterclockwise. This allows the operator to hold the sensor 100 with the protective wire clamping structure with their left hand and perform opening, wiring, clamping, and closing operations with their right hand during installation. This conforms to the operating habits of most operators and improves the efficiency of handheld suspended installation.

[0067] In particular, in some modified embodiments of this utility model, reference is made to the accompanying drawings of the specification of this utility model. Figure 13A and Figure 13B As shown, the side-turn protective cover 22 and the side-turn wire clamp 24 can also be configured to have the same lateral opening direction, so that the operator can use one hand to open the side-turn protective cover 22 and the side-turn wire clamp 24 in the same direction, which can ensure installation efficiency.

[0068] It is worth mentioning that in this utility model, the wiring part 11 has a wiring direction that is in the same direction as the detection direction of the sensor body 10, which makes it easier for the operator to connect the wires with one hand and organize the cables to the rear end, thus improving installation efficiency.

[0069] Further, the wire clamping seat 23 includes a wire clamping sill 231 and two limiting groove posts 232 erected at both ends of the wire clamping sill 231. Each limiting groove post 232 includes a multi-stage limiting wall 2321 and two guide limiting walls 2322 erected on both sides of the multi-stage limiting wall 2321. When the side-turning wire clamp 24 is inserted into the wire clamping seat 23, the side-turning wire clamp 24 is confined between the two limiting groove posts 232. The two guide limiting walls 2322 of one of the limiting groove posts 232 of the wire clamping seat 23 have a sliding groove along the insertion direction of the side-turning wire clamp 24. The device has a pivot shaft that matches the sliding groove. The side-turning wire clamp 24 is rotatably mounted on the wire clamping seat 23 with the pivot shaft inserted into the sliding groove. The pivot shaft can slide along the sliding groove, and when the pivot shaft slides to the top of the sliding groove, the sliding groove forms a limit on the pivot shaft in the insertion direction. The side-turning wire clamp 24 can be flipped relative to the wire clamping seat 23 with the pivot shaft as the axis. This allows the side-turning wire clamp 24 to be flipped and pressed towards the wire clamping threshold 231 without disassembling the accessories, ensuring a firm limit on the cable and facilitating operation by the operator.

[0070] Further, the side-turn protective cover 22 has a pivot end 221 and a snap-fit ​​end 222 opposite to the pivot end 221. The side-turn protective cover 22 is rotatably mounted on the protective base 21 at the pivot end 221, that is, the pivot of the side-turn protective cover 22 is set at the pivot end 221. The side-turn protective cover 22 has a closed state and an open state opposite to the closed state. The snap-fit ​​end 222 and the protective base 21 are provided with a first snap-fit ​​portion 251 and a second snap-fit ​​portion 252 that match each other. One of the first snap-fit ​​portion 251 and the second snap-fit ​​portion 252 is provided on the side-turn protective cover 22. The locking end 222, the other of the first locking part 251 and the second locking part 252 is disposed on the protective seat 21, wherein the first locking part 251 has a first hook 2511 and a second hook 2512 protruding from the locking end 222 of the side-turn protective cover 22 or the protective seat 21 to form an opening operation gap between the first hook 2511 and the second hook 2512, wherein in the closed state, the first hook 2511 and the second hook 2512 are both engaged with the second locking part 252, and are adapted to be used by a corresponding tool to open the cover when inserted into the opening operation gap.

[0071] In other words, when performing wiring operations, the operator can use the corresponding tool to insert into the opening operation gap to disengage the first hook 2511 and the second hook 2512 from the second locking part 252, so as to conveniently open the side-turn protective cover 22 while meeting safety requirements.

[0072] Preferably, the protective pressure wire housing 20 is detachably covered on the sensor body 10, so as to meet diverse packaging, transportation, installation and sales needs based on the detachable installation of the protective pressure wire housing 20. For example, the detachable installation of the protective wire-pressing housing 20 facilitates the packaging and transportation of the sensor 100 with the protective wire-pressing structure in a state where the sensor body 10 and the protective wire-pressing housing 20 are separated. Furthermore, the protective wire-pressing housing 20 can be sold separately from the sensor body 10 as an accessory. Manufacturers can also flexibly launch different products for different regions. For instance, in regions with exposed wiring and power cord restrictions, a sensor 100 with the protective wire-pressing structure, including the sensor body 10 and the protective wire-pressing housing 20, can be launched to meet safety regulations. In regions without such regulations, the sensor body 10 can be sold separately, reducing the sensor's price. For manufacturers, this avoids the need to design different products for different regions, saving development and mold costs. Additionally, in some application scenarios, the detachable protective wire-pressing housing 20 allows the sensor body 10 to be used in surface-mounted installations, improving product flexibility.

[0073] Specifically, please refer to the accompanying drawings in the specification of this utility model. Figures 8A to 8J The installation process of the sensor 100 with the protective pressure wire structure is illustrated. For shipment, the sensor body 10 is generally packaged and transported separately from the protective pressure wire housing 20; therefore, corresponding to... Figure 8A When the operator receives the product, the protective pressure wire housing 20 is first placed over the rear end of the sensor body 10 to install the protective pressure wire housing 20.

[0074] Corresponding to Figure 8B and Figure 8C The operator can hold the sensor 100 with the protective wire-pressing structure in one hand and the tool in the other hand, and insert the tool into the opening operation gap. Specifically, a flathead screwdriver is inserted into the opening operation gap to disengage the snap-fit ​​end 222 of the side-turn protective cover 22 from the protective seat 21, and then flip the side-turn protective cover 22 open to expose the wiring part 11.

[0075] Corresponding to Figure 8DThe operator pulls the side-turn wire clamp 24 away from the wire clamp 231 and flips it in the opposite direction to the opening direction of the side-turn protective cover 22 to open the wire clamp seat 23. This ensures that the flipping of the side-turn wire clamp 24 is not blocked by the side-turn protective cover 22, thus guaranteeing a large-angle flipping of the side-turn wire clamp 24 and avoiding obstruction in the wire insertion direction.

[0076] Corresponding to Figure 8E After opening the side-turn wire clamp 24, the operator inserts the cable into the connector 11 and places the cable on the wire clamp 23 to form a neat and standardized cable exit.

[0077] Corresponding to Figure 8F After completing the wiring, the operator flips the side-turn wire clamp 24 towards the wire clamping base 23 and presses the side-turn wire clamp 24 down towards the wire clamping base 23 to clamp the cable between the side-turn wire clamp 24 and the wire clamping base 23, thus completing the wire clamping operation and limiting the cable position.

[0078] Corresponding to Figure 8G After the wire pressing is completed, the side-turn protective cover 22 is flipped over to close the protective wire pressing housing 20, thus completing the wiring, wire pressing, and cover closing operations. It is worth mentioning that, during these operations, the operator can hold the sensor 100 with the protective wire pressing structure in one hand and operate it with the other hand, making the operation convenient and efficient.

[0079] Corresponding to Figure 8H After completing the above operations, the operator sets the relevant parameters of the sensor body 10 based on the setting window 16 on the sensor body 10 according to actual needs.

[0080] Corresponding to Figure 8I After setting the parameters, the operator holds the spring clip of the sensor 100 with the protective wire clamp and inserts the sensor 100 with the protective wire clamp into the mounting port on the corresponding mounting plate.

[0081] Corresponding to Figure 8J The sensor 100 with a protective wire-pressing structure is embedded and installed on a corresponding mounting plate, thereby completing the installation operation of the sensor 100 with a protective wire-pressing structure.

[0082] It is worth mentioning that, through Figures 8A to 8J As can be seen, the sensor 100 with the protective wire-pressing structure is quick and easy to install, without the need to disassemble any parts. The operator can complete various operations while holding the sensor 100 with the protective wire-pressing structure in the air, which meets safety requirements while ensuring installation efficiency.

[0083] Furthermore, in order to improve the firmness of the protective pressure wire housing 20 covering the sensor body 10, the protective base 21 includes a base portion 214 and a skirt portion 211 extending downward from the base portion 214. The sensor body 10 has a plug portion 14 that matches the skirt portion 211, so that when the protective pressure wire housing 20 is covering the sensor body 10, the skirt portion 211 and the plug portion 14 are engaged and fixed to form a limit on the protective pressure wire housing 20.

[0084] Furthermore, the bottom of the base portion 214 and the rear end of the sensor body 10 have mutually matching insertion structures 213 and 13. For example, the bottom of the base portion 214 is provided with a protruding mounting post 213, and the rear end of the sensor body 10 is provided with a mounting hole 13 that matches the mounting post 213. Thus, when the protective pressure wire housing 20 covers the sensor body 10, the mounting post 213 is inserted into the mounting hole 13 to limit the protective pressure wire housing 20.

[0085] Furthermore, the skirt 211 and the sensor body 10 are also provided with matching snap-fit ​​structures 212 and 15. For example, the skirt 211 is provided with a slot 212, and the sensor body 10 has a snap-fit ​​15 that matches the slot 212. Thus, when the protective pressure wire housing 20 is covered by the sensor body 10, the snap-fit ​​15 is inserted into the slot 212 to limit the protective pressure wire housing 20.

[0086] Furthermore, the side-turn protective cover 22 is provided with a flip-top buckle 221, and the sensor body 10 is provided with a mounting structure that matches the flip-top buckle 221, so that when the side-turn protective cover 22 is in the closed state, the flip-top buckle 221 is engaged with the mounting structure to ensure the closing stability of the side-turn protective cover 22.

[0087] It is worth mentioning that in the above structures, the sensor 100 with the protective wire-pressing structure is an infrared sensor, wherein the sensor body 10 can be used as a standalone infrared sensor product, see reference. Figures 9A to 9C As shown, the structure of the sensor body 10 is specifically illustrated. The sensor body 10 is an infrared sensor and includes a lens 12.

[0088] Refer to the accompanying drawings in the specification of this utility model. Figure 9D and Figure 9EThe sensor body 10 includes a main housing 101 and a cover 102. The main housing 101 is cylindrical, and the cover 102 has a connecting ring 1021 that matches the main housing 101. When the cover 102 is installed on the main housing 101, the connecting ring 1021 engages with the main housing 101. Specifically, the main housing 101 has a slot 1011, and the connecting ring 1021 has a mounting buckle that matches the slot 1011, so that the connecting ring 1021 can engage with the main housing 101 based on the engagement of the mounting buckle and the slot 1011.

[0089] It is worth mentioning that in these structures of the present invention, the face cover 102 further includes a positioning arc plate 1022. The positioning arc plate 1022 is arranged around the connecting ring 1021 and forms an installation gap between the positioning arc plate 1022 and the connecting ring 1021. The main housing 101 has an inner recess 1012 that matches the positioning arc plate 1022. When the face cover 102 is installed on the main housing 101, the positioning arc plate 1022 is embedded in the inner recess 1012, and the main housing 101 is clamped by the positioning arc plate 1022 and the connecting ring 1021. This provides installation positioning and limitation, and also helps to reduce the thickness of the connecting ring 1021, thus avoiding deformation and shrinkage of the face cover 102 at this position due to the thickness of the connecting ring 4221 during the processing of the face cover 102. This helps to maintain the aesthetic appearance of the face cover 102. Figure 9E As can be seen, the face cover 102 does not need to be provided with decorative grooves to cover the shrinkage, and can maintain a flat design on the detection surface.

[0090] Specifically, refer to Figure 10As shown, preferably, in this embodiment of the present invention, the lens 12 preferably adopts a folded form. Specifically, the lens 12 has a central lens group 121, a wide-angle lens group 122 arranged in a staggered manner relative to the central lens group 121, and a junction 123 connecting the central lens group 121 and the wide-angle lens group 122. Both the central lens group 121 and the wide-angle lens group 122 are lens groups formed by an array of multiple lens units, wherein the lens group passing through the central lens group 121... The physical center point of the light-receiving surface 1210 and the axis perpendicular to the light-receiving surface 1210 of the central lens group 121 are the central axis of the central lens group 121. Along the central axis, with the light-receiving surface 1210 of the central lens group 121 facing forward, the central lens group 121 and the wide-angle lens group 122 satisfy the following conditions on the same cross section along the central axis 1211: the central lens group 121 has a structure that is low in the middle and high at both ends; the light-receiving surface 1220 of the wide-angle lens group 122 faces away from the central axis. The lower end of the wide-angle lens group 122 on the same side of the line is lower than the upper end of the central lens group 121 and is farther away from the central axis relative to the upper end of the central lens group 121. The upper end of the wide-angle lens group 122 on the same side of the central axis is higher than the upper end of the central lens group 121 and is farther away from the central axis relative to the lower end of the wide-angle lens group 122. With respect to the line connecting the lower end of the wide-angle lens group 122 to the upper end of the central lens group 121 on the same side of the central axis, the wide-angle lens group 122 on that side at that cross-section... The focal point of the lens unit of lens group 122 is located above the connecting line, so that the lens 12 has a staggered segmented light-gathering surface design. In the state of the staggered segmented light-gathering surface design of the lens 12, the junction 123 connecting the central lens group 121 and the wide-angle lens group 122 is prevented from blocking the effective light-gathering angle of the wide-angle lens group 122. Therefore, compared with the overall convex light-gathering surface shape, the staggered segmented light-gathering surface design can meet the requirements of large light-gathering surface area and small volume under the design of fixed effective light-gathering angle.

[0091] It is worth mentioning that, based on the design of this utility model, the protective pressure wire housing 20 is also suitable for ordinary infrared sensors, see reference. Figures 11A to 11C The sensor body 10 is an infrared sensor and has a lens 12, wherein the lens 12 is a common infrared lens.

[0093] Further reference is made to the accompanying drawings in the specification of this utility model. Figure 12A and Figure 12B As shown, the sensor body 10 is configured as a microwave sensor, reference... Figure 12C , for the corresponding Figure 12A and Figure 12B The sensor body 10 shown is equipped with the protective wire clamping housing 20. That is to say, the protective wire clamping housing 20 is suitable for infrared sensors and microwave sensors, so that the corresponding sensors meet safety requirements based on the setting of the protective wire clamping housing 20.

[0094] It is worth mentioning that the protective wire clamping housing 20 can be designed to be transparent. For example, the protective wire clamping housing 20 can be made completely transparent, or a portion of the protective wire clamping housing 20 can be made transparent to make it semi-transparent. For example, the side-turn protective cover 22 can be designed to be transparent. Based on the transparent design of the protective wire clamping housing 20, it is convenient for the user to observe the internal condition of the wiring part 11 when the protective wire clamping housing 20 is closed, which is beneficial for the inspection and maintenance of the sensor 100 with the protective wire clamping structure.

[0095] It is understood that the side-turning wire clamp 24 can also be designed to be transparent so that the operator can visually see the wire clamping status and facilitate the inspection and maintenance of the sensor 100 with the protective wire clamping structure.
