[0001] The utility model relates to the technical field of sockets, in particular to a fixed surface-mounted socket. Background Art
[0002] The track socket of the prior art usually consists of a socket and a movable track. There is no need to make grooves in the wall to bury the wires. It is only necessary to install the movable track on the wall. The socket can be moved on the slide rail. At the same time, the corresponding number of sockets can be increased according to the number of devices used, thereby improving the efficiency of socket replacement and increase and decrease. However, the track and other structures of the track socket of the prior art are exposed to the outside, which is easy to get into water, dust and debris, etc., not only has low reliability but also has potential safety hazards; in addition, since the socket and the movable track are in a slidable connection relationship, the main body of the socket is located above the movable track, there is a lack of reliable fixing relationship between the main body of the socket and the movable track, and the socket is located at a high position, so the overall stability of the socket is poor, and it is easy to loosen, resulting in a decrease in the tightness of the electrical connection between the socket and the movable track, affecting the reliability of the socket. The Chinese patent document with publication date of January 29, 2021 and publication number of CN112290276A discloses an electric track socket, including a socket track and a sealing seat cover, the back of the socket track is provided with an alloy buckle, and the upper surface of the socket track is provided with a guide slot, the outer side of the guide slot is nested with a socket panel, and the outer side of the socket panel is provided with a plug hole, the sealing seat cover is installed on both sides of the socket track, and the outer side of the socket track is nested with a power line, the outer side of the socket track is provided with a positioning hole, and double-sided tape is bonded and fixed between the positioning holes, the inside of the socket track is welded and fixed with a wire connection seat, and a vertical conductive column is provided directly below the wire connection seat, and the bottom of the vertical conductive column is nested with a conductive panel. The electric track socket adopts alloy buckles and guide slide bars, and the back of the socket track is fixed and limited by alloy buckles of different widths, which plays a certain role in the stability of the socket on the mobile track. However, the track and other structures of the track socket are exposed to the outside, which is easy to get into water, dust and debris, etc., and the problem of low reliability and potential safety hazards has not been solved. Utility Model Content
[0003] The purpose of the utility model is to solve the above-mentioned deficiencies of the track sockets in the prior art and to provide a fixed surface-mounted socket to solve the problems of the track sockets in the prior art, such as poor stability, easy ingress of water, dust and debris, low reliability and potential safety hazards. The utility model has the advantages of good socket stability, high protection level and good reliability.
[0004] The specific technical solution adopted by the utility model to solve the above technical problems is a fixed surface-mounted socket, including a long strip-shaped bottom box, a conductive connection cavity is provided in the bottom box, a conductive strip parallel to the length direction of the bottom box is provided in the conductive connection cavity, a plurality of socket holes are provided on the top plate of the bottom box, a detachable socket is embedded in the socket hole, the socket includes a socket and a pin corresponding to the socket, and when the socket is used, the pin is electrically connected to the conductive strip through an electrical connection mechanism. The surface-mounted socket of the utility model has a socket hole in the bottom box, and a detachable socket is embedded in the socket hole, so that the internal structure such as the track is not exposed to the outside, which causes problems such as easy ingress of water, dust and debris, greatly improves the protection level and reliability, and reduces safety hazards.

For a three-pole socket, the structure in which the L-pole conductive strips and N-pole conductive strips are located on both sides of the E-pole conductive strips and their positions are higher than the E-pole conductive strips is conducive to the electrical connection between the pins and the conductive strips. When the bottom box is made of conductive material (such as aluminum alloy), the bottom box itself is equivalent to the E-pole conductive strip (that is, the shell is grounded).
[0006] Preferably, the socket is circular, including a base and a socket cover, a rotating ring is provided between the base and the socket cover, the L-pole pin and the N-pole pin are electrically connected to a horizontally arranged conductive pin, and the conductive pin is in transmission connection with the rotating ring; when the rotating ring rotates, the conductive pin is connected or disconnected with the conductive strip. The rotating ring between the base and the socket cover is used to control the connection or disconnection of the conductive pin and the conductive strip. Unlike the track socket, the rotating ring of the utility model is equivalent to a power switch, and the power supply on the socket can be disconnected when the socket is not in use, thereby improving its safety; and if the conductive pin and the conductive strip of the track socket are disconnected, the socket will fall off from the bottom box, so once the socket is inserted into the bottom box, it is always in a powered state, and the power indicator light on the socket is always on to consume power; if the socket is removed, it needs to be re-inserted when it is used again; in addition, removing the socket will cause large sections of the track and other internal structures to be exposed, which is prone to safety hazards.
[0007] Preferably, the L-pole conductive strip and the N-pole conductive strip both include an insulating groove and a power supply strip embedded in the insulating groove. The conductive pin is arranged horizontally, and the conductive pin is connected to the L-pole pin and the N-pole pin through a conductive shaft, and the conductive shaft is connected to the rotating ring in a transmission manner. The E-pole pin is electrically connected to the grounding pin, and a compression spring is provided at the upper end of the grounding pin, and the lower end of the grounding pin abuts against the bottom box or the E-pole conductive strip arranged on the bottom box. The L-pole conductive strip and the N-pole conductive strip both include an insulating groove and a power supply strip (conductor) embedded in the insulating groove. The insulating groove is used for insulation isolation, and one side of the insulating groove is opened to expose the power supply strip, which is convenient for connection with the conductive pin. When the bottom box is made of metal conductive material (such as aluminum alloy), the grounding pin is directly connected to the bottom box. When the bottom box is made of insulating material (such as plastic), the grounding pin is connected to the E-pole conductive strip arranged on the bottom box. In order to ensure reliable connection, a compression spring is provided at the upper end of the grounding pin, thereby ensuring that the grounding pin is in good contact with the ground.

The limiting groove cooperates with the limiting strip at the bottom of the socket to fix the relative position of the conductive latch on the socket, ensuring that the conductive latch is reliably connected to the power supply strip on the conductive strip when it rotates, and the limiting strip does not shake, ensuring a stable connection.
[0009] Preferably, the socket is symmetrically provided with a snap-fit mechanism on both sides, and the socket is snap-fitted with the top plate of the bottom box through the snap-fit mechanisms on both sides; the snap-fit mechanism includes buttons on both sides of the socket and a snap-fit tongue below the button, and a snap-fit spring is provided on the inner side of the button. The snap-fit mechanism is used to fix the socket on the top plate of the bottom box to ensure that the socket is firmly connected to the bottom box. When the socket is installed on the bottom box, the snap-fit tongue below the button snaps the top plate, and the limit bar at the bottom of the socket snaps into the limit groove, so that the socket cannot move or rotate, ensuring the stability of the socket; at the same time, because the socket completely closes the socket hole, it avoids the internal structure such as the track being exposed to the outside, causing problems such as easy ingress of water, dust and debris, thereby improving the protection level and reliability and reducing safety hazards.
[0010] Preferably, a protective door partition is provided above the pin, a slide groove is provided on the protective door partition, a protective door is provided in the slide groove, an inclined surface is provided at the protective door and the pin, a reset spring is provided on one side of the protective door, and the other end of the reset spring abuts against the protective door partition. The protective door partition cooperates with the protective door and the reset spring, so that the protective door can move in the slide groove on the protective door partition, and is used to close the L-pole pin and the N-pole pin when the socket is not in use, thereby reducing safety hazards.
[0011] Preferably, the bottom box and the conductive strip are both long strips of uniform cross-section profiles, and end caps are provided at both ends of the bottom box, and a terminal is provided in the end cap on one side. The bottom box and the conductive strip are both long strips of uniform cross-section profiles, and the length can be cut according to the number of sockets, etc. The terminal is used to connect the conductive strip to the power supply.
[0012] Preferably, the socket holes on the bottom box are easy-tear holes, which are arranged at equal intervals on the top plate of the bottom box, and the fixed surface-mounted socket also includes a sealing cover adapted to the socket hole. For a bottom box made of plastic material, an easy-tear hole that is easy to tear is further processed on the top plate of the bottom box as a socket hole, which is removed when the socket is installed to form an embedded position of the socket; the position where the socket is not temporarily installed can be retained as it is, so that the position of the easy-tear hole is still in a closed state, which can prevent the intrusion of water vapor, dust, etc. The sealing cover is used to remove the socket hole of the socket for sealing.
[0013] The beneficial effect of the utility model is that the socket is detachably installed in the circular hole of the bottom box by a buckle, so that the socket is stable relative to the bottom box structure and will not shake, thereby improving reliability. In addition, only the socket hole is exposed to the outside, and the power connection structure inside the bottom box is enclosed in the bottom box, which has the functions of waterproof, vapor-proof and dust-proof, solves the problem of low protection level of the guide groove penetrating the surface of the existing track socket shell, so that the whole device can achieve a higher waterproof, dust-proof and anti-fouling effect; in addition, because the socket is embedded in the bottom box, the overall height of the device is effectively reduced by 20-30%, thereby making the structure simpler and more sophisticated, convenient to process, easy to install, easy to carry and reliable to work.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.
[0024] Example 1
[0025] exist Figure 1 Figure 2 In the embodiment 1 shown, a fixed surface-mounted socket includes a long strip-shaped base box 1, a conductive connection cavity 2 is provided in the base box 1, a conductive strip parallel to the length direction of the base box 1 is provided in the conductive connection cavity 2, a socket hole 4 is provided on the top plate 3 of the base box 1, and the number of the socket holes is determined according to the number of sockets to be installed. In this embodiment, four socket holes are provided, and a detachable socket 5 is embedded in the socket hole. The socket includes a socket 6 and pins corresponding to the socket, wherein the socket and the pins are arranged in a manner prescribed by the national standard, and a power connection mechanism is provided at the bottom of the socket. When the socket is in use, the pins are electrically connected to the conductive strips respectively through the power connection mechanism.
[0026] The pins of this embodiment are arranged on the pin fixing seat 7 inside the socket. For a three-pole socket, the pins include an L-pole pin 8, an N-pole pin 9 and an E-pole pin 10 (ground pin), and the conductive strips include an L-pole conductive strip 11, an N-pole conductive strip 12 and an E-pole conductive strip 22 corresponding to the L-pole pin 8, the N-pole pin 9 and the E-pole pin 10, wherein the L-pole conductive strip and the N-pole conductive strip are located on both sides of the E-pole conductive strip and are symmetrically arranged, and the positions of the L-pole conductive strip and the N-pole conductive strip are higher than the E-pole conductive strip. Here, the structure in which the L-pole conductive strip and the N-pole conductive strip are located on both sides of the E-pole conductive strip and are higher than the E-pole conductive strip is conducive to the electrical connection between the pins and the conductive strips, and avoids the E-pole conductive strip from interfering with the above electrical connection.
[0027] The socket is circular and includes a base 14 and a socket cover 15. A rotating ring 16 is provided between the base and the socket cover. The rotating ring between the base and the socket cover is used to control the connection or disconnection of the conductive pin and the conductive strip. The L-pole pin and the N-pole pin are connected to a conductive shaft 40 (see Figure 6 ) is electrically connected to a horizontally arranged conductive pin 17 (see Figure 3 ), the conductive plug 17 can rotate around the conductive rotating shaft 40 while maintaining electrical connection, and the conductive plug is connected to the rotating ring 16 of the socket in a transmission manner; when the rotating ring rotates, the rotating ring drives the conductive plug to rotate, so that the conductive plug and the conductive strip are in an electrically connected state or disconnected state. Unlike the track socket, the rotating ring of the utility model is equivalent to a power switch. When the socket is not in use, the conductive plug and the conductive strip can be disconnected by rotating the rotating ring, thereby disconnecting the power supply to the socket. In this way, the socket is powered off, which can improve the safety of electricity use; for the track socket of the prior art, if the conductive plug is disconnected from the conductive strip, the socket will fall off from the bottom box 1, so once the socket is inserted into the bottom box 1, it is always in a powered state, and the power indicator light on the socket is always on to consume electricity. If the socket is removed, it needs to be re-inserted when it is used again; in addition, removing the socket will cause large sections of the internal structure such as the track to be exposed, which not only reduces the protection level, but also easily leads to safety hazards. The socket of the utility model is also provided with an indicator light 35, which is connected to the L-pole pin 8 and the N-pole pin 9 through a wire, and a light guide block 36 is provided above the indicator light (see Figure 2 ), the upper end of the light guide block 36 is adapted to the indicator light hole set on the socket cover 15, and is used to guide the light of the indicator light to indicate the power-on status of the socket.
[0028] For a three-pole socket, the L-pole conductive strip and the N-pole conductive strip each include an insulating groove strip 18 and a power supply strip 19 embedded in the insulating groove strip. The insulating groove strip surrounds the power supply strip and leaves only a notch 38 on the opposite side (inner side) (see FIG. Figure 4), so that the conductive plug can enter and be electrically connected to the power supply bar. The conductive plug is arranged horizontally. In order to facilitate the conductive plug to enter the gap, a guide opening 39 with a narrow inside and a wide outside is also arranged on the outer side of the gap of the insulating slot. The conductive plug is connected to the L-pole pin and the N-pole pin in a rotational manner through the transmission of the vertically arranged conductive shaft, and the conductive shaft is driven by the rotation of the dependent rotating ring to achieve transmission connection; in order to ensure the reliable connection between the conductive plug and the power supply bar, the cross section of the power supply bar here adopts a horizontal U-shape, and an eight-shaped elastic joint is formed at its opening, which facilitates the smooth entry of the conductive plug on the one hand, and ensures close contact on the other hand. The E-pole pin is always electrically connected to the grounding plug 20. The upper end of the grounding plug is provided with a compression spring 21 for pressing the grounding plug. The lower end of the grounding plug abuts against the E-pole conductive strip 22 arranged on the bottom box 1. The bottom box 1 of this embodiment is a plastic product. A groove is provided at the bottom of the conductive connection cavity 2. Two T-shaped strips 37 are provided on the bottom of the groove. A receiving groove for the E-pole conductive strip 22 is formed between the two T-shaped strips 37. The E-pole conductive strip 22 adopts a conductive copper plate and is inserted into the receiving groove located at the center of the bottom of the conductive connection cavity 2.
[0029] A positioning structure for fixing the conductive strip is formed between the T-shaped strip 37 and the groove walls on both sides. At the same time, slots 41 are provided on the groove walls on both sides. The conductive strip is correspondingly provided with protruding inserts 42, which are inserted into the slots to fix the conductive strip. Fixing holes 43 are also provided on both sides of the conductive connection cavity 2. The fixing holes 43 are used to fix the end covers 33 at both ends of the bottom box 1. The L-pole conductive strip and the N-pole conductive strip both include an insulating groove and a power supply strip (power supply conductor) embedded in the insulating groove. The insulating groove is used for insulation isolation. One side of the insulating groove is opened to expose the power supply strip, which is convenient for connection with the conductive plug.
[0030] In this embodiment, the L-pole conductive strip and the N-pole conductive strip are symmetrically arranged, and a limiting groove 23 is formed between the insulating groove strip of the L-pole conductive strip and the insulating groove strip of the N-pole conductive strip. A limiting strip 24 adapted to the limiting groove is provided at the bottom of the socket (see Figure 3), a latch window 25 is formed on the limit bar 24, and the conductive latch 17 is located in the latch window 25. When the conductive latch 17 is in an electrically connected state with the conductive bar, the conductive latch 17 and the limit bar 24 are approximately in a vertical state, and when the conductive latch 17 and the conductive bar are in a disconnected state (storage state), the conductive latch 17 and the limit bar 24 are in a parallel state and located within the contour of the limit bar 24. The rotation of the conductive latch 17 is driven by the rotation of the rotating ring 16, and the rotation of the rotating ring 16 drives the conductive shaft 40 to rotate, and the conductive latch 17 is vertically fixedly connected to the conductive shaft 40. In this structure, the limit groove cooperates with the limit bar at the bottom of the socket, which can limit the position of the upper limit bar 24 of the socket, and then limit the relative position of the conductive latch 17, ensuring that the conductive latch 17 is reliably connected to the power supply bar on the conductive bar when rotating, and the limit bar does not shake, ensuring stable connection; while the track socket of the prior art has poor stability because the socket can move relative to the bottom box 1 and the socket body lacks a fixed structure. The socket of this embodiment is symmetrically provided with a clamping mechanism on both sides, and the socket is clamped with the top plate 3 of the bottom box 1 through the clamping mechanisms on both sides; the clamping mechanism includes buttons 26 located on both sides of the socket and a clamping tongue 27 located below the button, and a buckle spring 28 is provided on the inner side of the button. The clamping mechanism is used to fix the socket on the top plate 3 of the bottom box 1 to ensure that the socket is firmly connected to the bottom box 1. When the socket is installed on the bottom box 1, the clamping tongue below the button clamps the top plate 3, and the limiting strip at the bottom of the socket is clamped into the limiting groove, so that the socket cannot move or rotate, ensuring the stability of the socket; at the same time, because the socket completely closes the socket hole, it avoids the internal structure such as the track being exposed to the outside, causing problems such as easy ingress of water, dust and debris, improving the protection level and reliability, and reducing safety hazards.
[0031] In this embodiment, a protective door partition 29 is provided above the pins (see Figure 7 ), the two ends of the protective door partition are bent upward to form a folding plate 44, and a slide groove is formed between the two folding plates 44. A protective door 30 is slidably arranged in the slide groove. A pin hole 46 is arranged at the corresponding position of the protective door 30 and the pin, and a bevel 31 is arranged on one side of the pin hole. A reset spring 32 is arranged on the side of the protective door located on the pin hole with the bevel 31, and the other end of the reset spring abuts against a positioning baffle 45 of the protective door partition. When no plug is inserted into the socket, the protective door 30 closes the socket under the action of the reset spring, and the bevel is located below the socket; when the plug is inserted into the socket, the plug acts on the bevel, so that the protective door 30 overcomes the elastic force of the reset spring and moves in the opposite direction to expose the socket, so that the plug can be inserted smoothly. The utility model adopts closing measures for both the L-pole pin and the N-pole pin to ensure safety, and the opening of the protective door corresponding to the E-pole pin is larger and is always in an open state. The protective door partition cooperates with the protective door and the reset spring, so that the protective door can move in the slide groove on the protective door partition, and is used to close the L-pole pin and the N-pole pin when the socket is not in use, thereby reducing safety hazards.
[0032] The bottom box 1 and the conductive strip of the utility model are both long strips of uniform cross-section profile structure, wherein the L-pole conductive strip and the N-pole conductive strip are composed of an outer insulating groove and an inner power supply strip, and the insulating groove and the power supply strip are both profiles. The two ends of the bottom box 1 are provided with end caps 33 (see Figure 5 ), a terminal 34 is arranged in the end cover on one side. For a three-pole socket, there are three terminal 34. The position corresponding to the fixing hole 43 on the end cover 33 is provided with a corresponding screw installation hole. The end cover 33 can be fixed to the two ends of the bottom box 1 by self-tapping screws; the end cover 33 is also provided with a lead hole to facilitate the lead-out of the power cord. The bottom box 1 of this embodiment is a plastic profile, and the socket holes on the bottom box 1 are easy-to-tear holes, which are arranged at equal intervals on the top plate 3 of the bottom box 1. The fixed surface-mounted socket also includes a sealing cover (not shown in the figure) adapted to the socket hole. The bottom box 1 and the conductive strip are both long strips of equal cross-section profiles, and the length can be cut according to the number of sockets, etc. The top plate 3 of the bottom box 1 is processed to form an easy-tear hole as a socket hole, which is removed when the socket is installed to form the embedded position of the socket; the position where the socket is not installed temporarily can be retained as it is, so that the position of the easy-tear hole is still in a closed state, which can prevent the invasion of water vapor, dust, etc. The sealing cover is used to seal the socket hole where the socket is removed to prevent water vapor, dust, etc. from invading from the opened socket hole. The thickness of the bottom box of the utility model is not more than 16mm. Generally, the design thickness of the bottom box of the prior art is 20mm, while the thickness of the bottom box of this embodiment is 15.8mm. The thickness of the socket body of the utility model is not more than 20mm (excluding the raised limiting strip at the bottom). Generally, the main body thickness of the track socket in the prior art is 29mm (excluding the raised limiting strip at the bottom), while the thickness of the socket body of this embodiment is 20mm. In addition, since the socket of the utility model is partially embedded in the bottom box, its total thickness is much smaller than the total thickness of the track socket in the prior art. Generally, the total thickness of the track socket in the prior art is 20mm+29mm=49mm, while the total thickness of the bottom box plus the socket in this embodiment is about 32mm, which significantly reduces the total thickness.
[0033] Example 2
[0034] In Example 2, when the bottom box is made of conductive material (such as aluminum alloy profile), the bottom box itself is equivalent to the E-pole conductive strip. In this case, the E-pole conductive strip can be omitted, and the grounding pin is directly connected to the bottom box (that is, the outer shell is grounded). In addition, when the bottom box is made of conductive material (such as aluminum alloy profile), socket holes (that is, non-easy-to-tear holes) can be directly set on the top plate of the bottom box to better install the sockets. When the number of sockets is less than the number of socket holes, the redundant socket holes are closed with sealing covers to prevent the intrusion of water vapor, dust, etc., and the rest of the structure is the same as that of Example 1.
[0035] When assembling the utility model, first cut a base box (profile) of appropriate length. Since the conductive connection cavity of the base box is preset with installation positions for the L-pole conductive strip, the N-pole conductive strip and the E-pole conductive strip, the L-pole conductive strip, the N-pole conductive strip and the E-pole conductive strip can be conveniently plugged into the conductive connection cavity of the base box. The E-pole conductive strip here is only applicable to base boxes with insulating structures. For example, the base box is made of plastic profiles. For base boxes made of metal materials such as aluminum alloy, there is no need to install the E-pole conductive strip. The base box itself has the function of the E-pole conductive strip, and the grounding pin can be directly connected to the base box. Then install end covers at both ends of the base box, connect the power supply strip on the L-pole conductive strip, the power supply strip on the N-pole conductive strip and one end of the E-pole conductive strip to the wiring terminal and lead out the power line, and fix the end cover to the fixing hole of the base box by self-tapping screws. In this way, the entire fixed surface-mounted socket can work normally. In the overall structure of the utility model, only the socket hole is exposed outside. After the bottom box and the socket are installed, a fixed surface-mounted socket with waterproof, dustproof and anti-fouling functions is formed, which solves the shortcomings of the guide slots penetrating the surface of the bottom box of the existing track socket that are not waterproof, dustproof and anti-fouling, so that the entire fixed surface-mounted socket can achieve a higher waterproof, dustproof and anti-fouling effect. After installation, the thickness is reduced by at least 30% compared with the existing track socket. The structure is simple and exquisite, convenient to process, easy to install, easy to carry and reliable to work.
[0036] In addition to the above-mentioned embodiments, within the scope disclosed in the claims and the specification of the utility model, the technical features or technical data of the utility model can be reselected and combined to form new embodiments, which can be achieved by those skilled in the art without creative work. Therefore, these embodiments that are not described in detail in the utility model should also be regarded as specific embodiments of the utility model and within the protection scope of the utility model.
