Description

Technical Field

[0001] This utility model relates to the technical field of sensor switches, and in particular to a long-life, quick-replacement sensor switch for cabinet lights. Background Technology

[0002] Nowadays, cabinets, wardrobes, wine cabinets, shoe cabinets and other furniture are often equipped with lighting fixtures. These fixtures serve both lighting and ambiance creation functions, while sensor switches for cabinet lights are used to control the on / off state or adjust the brightness of the lights.

[0003] Traditional inductive switches are mainly divided into two types: integrated switch body and wire design, and separate design. To ensure a stable installation and prevent detachment, both structures typically have the sensor head designed to be larger than the mounting hole. For integrated inductive switches, installation requires first threading the switch wire through the mounting hole from inside the cabinet before securing the switch body. However, because the wire is usually long and integrated with the switch, threading is often inconvenient. Separate inductive switches allow the switch body to be inserted into the mounting hole from inside the cabinet first, and then the wire is connected from the outside. While this simplifies the installation process and eliminates the need for threading, it requires a socket below the switch body and a plug at the wire end for assembly, undoubtedly increasing the cost of the inductive switch. Furthermore, both structures share a common problem: if the sensor head is damaged, the entire switch must be removed from the mounting hole for replacement. This replacement method is time-consuming, labor-intensive, and wasteful of materials.

[0004] Chinese utility model patent CN221728315U discloses a pluggable installation structure for an inductive switch, comprising a kit. The kit has a slot at its bottom, into which a metal contact spring is embedded. The metal contact spring has a wire connection end at its end and a contact point at its upper end. The contact point connects to a connecting slot at the bottom of the inductive switch body. A movable plate is slidably connected to the middle of the inductive switch body. A power contact point is located at the connection between the inductive switch body and the contact point, and the power contact point is electrically connected to the contact point for conduction. This prior art, by installing the kit inside a cabinet panel, fixes the kit within the panel. The wire connection end of the kit achieves conductivity through connection with the wire. The inductive switch is directly inserted into the space within the kit, and the power contact of the inductive switch is electrically connected to the contact point of the kit. When the inductive switch malfunctions or reaches the end of its service life, it can be directly removed for replacement.

[0005] Although the aforementioned existing technologies offer improved ease of replacement compared to traditional inductive switches, they still have significant shortcomings: the overall structure is relatively complex, and no structure for heat dissipation has been disclosed.

When the plug 2 is installed in the socket 1, the contact piece 221 on the control circuit board 22 will press outward against the protrusion of the metal piece 5, causing the metal piece 5 to bend outward, thereby forming a stable and tight electrical contact between the metal piece 5 and the contact piece 221. When the control circuit board 22 is installed inside the socket 1, the three contact pieces 221 can cooperate with the metal pieces 5 on the three sockets 4 at the bottom of the socket 1 to complete the power connection.

[0040] Furthermore, in a preferred embodiment, the bottom end of the socket 1 is provided with at least one slot 11, which is used for the wire connecting the metal plate 5 and the power supply to pass through. The slot 11 is in communication with the inside of the socket 1, and the wire enters the inside of the socket 1 through the slot 11. The three electrodes of the wire are electrically connected to the metal plates 5 on the three plug sockets 4, respectively.

[0041] Furthermore, in a preferred embodiment, the sleeve 1 is a cylindrical structure; the top cover 21 is circular.

[0042] Furthermore, in a preferred embodiment, at least one ventilation slot 212 is provided on the edge of the top cover 21; a baffle 213 is provided along the edge of the top cover 21, and a plurality of spaced limiting blocks 214 are provided on the bottom side of the baffle 213. The plurality of limiting blocks 214 abut against the top of the side wall of the sleeve 1, thereby positioning and limiting the top cover 21.

[0043] Furthermore, in a preferred embodiment, two adjacent limiting blocks 214, the bottom side of the baffle 213, and the top of the circumferential sidewall of the sleeve 1 together form a gap, each gap communicating with a vent groove 212. This gap facilitates the removal of the plug 2 during disassembly, and the structural cooperation between this gap and the vent groove 212 forms a passage between the interior and exterior of the housing structure. The interior of the housing structure communicates with the exterior through multiple vent grooves 212, enabling air circulation.

[0044] Furthermore, in a preferred embodiment, the vent groove 212 extends through the top cover 21, please refer to... Figure 9 .

[0045] Furthermore, in a preferred embodiment, the top cover 21 is circular, and a plurality of ventilation slots 212 are evenly spaced along the circumferential edge of the top cover 21; an annular baffle 213 is provided along the circumferential edge of the top cover 21, and a plurality of evenly distributed limiting blocks 214 are provided on the bottom side of the baffle 213, and the plurality of limiting blocks 214 abut against the top of the circumferential sidewall of the sleeve 1, thereby positioning and limiting the top cover 21; furthermore, the outer diameter of the baffle 213 is the same as the outer diameter of the sleeve 1.

[0046] Furthermore, in a preferred embodiment, a plurality of elastic elements 12 are spaced apart on the side wall of the sleeve 1, and each elastic element 12 has a locking head 121 at its top. When the locking head 121 is subjected to an inward squeezing force, the elastic element 12 will bend and enter the interior of the sleeve 1.

[0047] Furthermore, in a preferred embodiment, the sleeve 1 is a cylindrical structure, and a plurality of elastic elements 12 are evenly spaced on the circumferential sidewall of the sleeve 1, and each elastic element 12 has a locking head 121 at its top.

[0048] Furthermore, in a preferred embodiment, eight longitudinally arranged slits are provided on the circumferential sidewall of the sleeve 1, extending downward from the top of the circumferential sidewall; each pair of slits forms a group, and four groups of slits are evenly spaced circumferentially, with the portion between the two slits in each group forming an elastic element 12; the longitudinal section of the clip 121 is a right-angled triangle, which facilitates guiding the elastic element 12 to contract during installation. After installation, the bottom surface of the clip 121 fits against the inner wall of the cabinet, serving as a limiting function to prevent it from falling off. In addition, the slits can also serve to allow for ventilation and heat dissipation.

[0049] Furthermore, in a preferred embodiment, a high-friction surface is provided on the outer wall of the circumferential sidewall of the sleeve 1, which forms an interference fit with the mounting hole after installation, thereby improving stability.

[0050] Furthermore, in a preferred embodiment, the elastic element 12 opens outward relative to the body of the sleeve 1. When installed in the mounting hole, the elastic element 12 applies a certain elastic force to the hole wall, which can improve installation stability. Compared with the prior art, this reduces the risk of loosening and further improves the overall performance and reliability of the product.

[0051] When this sensor switch is initially installed, it can be directly inserted into the mounting hole from the outside of the cabinet, along with the wire. The elastic element 12 on the socket 1 will retract inwards under the pressure of the mounting hole, ensuring the entire sensor switch can smoothly enter the mounting hole. When the socket 1 is in place, the locking head 121 at the upper end of the elastic element 12 will return to its original position under the action of the elastic force as it protrudes from the mounting hole, thus locking the socket 1 in place and securing it firmly within the mounting hole. Compared to traditional integrated sensor switches that require insertion into the mounting hole from the inside of the cabinet with the switch wire, the installation of this structure is much simpler.

[0052] Furthermore, in a preferred embodiment, the plug 2 further includes a clamping head 25, which is connected to the bottom side of the top cover 21. The clamping head 25 is used to connect the control circuit board 22 and the top cover 21. A clamping groove 251 is provided in the middle of the clamping head 25, and the top end of the control circuit board 22 is inserted into the clamping groove 251. The control circuit board 22 can be fixedly mounted on the clamping head 25 by interference fit with the clamping groove 251.

[0053] Furthermore, in a preferred embodiment, the clamping head 25 includes two symmetrically arranged clamping members, and a clamping groove 251 is formed between the two clamping members; the distance between the opposite sides of the two clamping members gradually decreases from top to bottom; the clamping head 25 has a certain elastic deformation capability, and when the control circuit board 22 is inserted into the clamping groove 251, it can be firmly clamped.

[0054] Furthermore, in a preferred embodiment, a sensor head 23 is provided on the control circuit board 22, and the sensor head 23 penetrates the top cover 21 to sense external signals.

[0055] Furthermore, in a preferred embodiment, the top cover 21 has a through hole 211 extending vertically, through which the sensor head 23 senses external signals.

[0056] Furthermore, in a preferred embodiment, the top surface of the top cover 21 is provided with a groove 215; the bottom of the groove 215 communicates with the through hole 211; the plug 2 also includes a filter 24, which is installed in the groove 215; the filter 24 serves to protect the sensor head 23 and filter light of a specific wavelength.

[0057] Furthermore, in a preferred embodiment, the sensor head 23 can be configured as a human body sensing sensor head, a hand-scanning sensing sensor head, or a touch sensing sensor head, etc.

[0058] Working principle:

[0059] The socket 1 is a cylindrical structure with an open top. The plug 2 is pluggably installed inside the socket 1. The plug 2 is freely inserted into the socket 1 through a limiting groove 31 on the socket 1 via a control circuit board 22. When the plug 2 is inserted into the socket 1, the control circuit board 22 on the plug 2 will be limited within the limiting groove 31. At the same time, the three contact pieces 221 below the control circuit board 22 will sequentially contact the metal pieces 5 on the three plug sockets 4 below the limiting groove 31 to achieve power connection. Simultaneously, when the plug 2 is installed inside the socket 1, the top cover 21 and the socket 1 together form a hollow shell structure. The limiting blocks 214 on the top cover 21 will press against the top of the circumferential sidewall of the socket 1, allowing air inside the shell structure to flow out through the gaps between the vent groove 212 on the top cover 21 and the multiple limiting blocks 214, thereby enhancing airflow inside the shell structure, achieving better heat dissipation, and extending the lifespan of the control circuit board 22.

[0060] When this sensor switch is installed for the first time, it can be directly inserted into the mounting hole from the back of the cabinet along with the switch wire. The elastic element 12 on the socket 1 will retract inward when it is squeezed by the mounting hole, thus ensuring that the entire sensor switch can be smoothly inserted into the mounting hole. When the socket 1 is installed in place, the clip 121 at the upper end of the elastic element 12 will reset under the action of the elastic force when it passes through the mounting hole, thus locking the socket 1 and making the socket 1 securely fixed in the mounting hole. Compared with the traditional integrated sensor switch, which requires the switch wire to be inserted into the mounting hole from the inside of the cabinet, the installation operation of this structure is much simpler.

[0061] When the inductive switch fails, the plug 2 can be pulled out of the socket 1 without disassembling the socket 1, and then the new plug 2 can be inserted into the socket 1 to complete the replacement, which is more efficient and faster.

[0062] In summary, this utility model includes a socket 1 and a plug 2, with the plug 2 detachably installed inside the socket 1. The plug 2 includes a top cover 21 and a control circuit board 22, which are detachably connected. When the control circuit board 22 is damaged, it can be replaced separately. Compared to traditional inductive switches, replacement is more convenient and cost-effective. The plug 2 mainly consists of the top cover 21 and the control circuit board 22, resulting in a simpler structure. Furthermore, the control circuit board 22 is directly exposed inside the socket 1, and the ventilation inside the socket 1 improves heat dissipation and extends its lifespan.

[0063] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
