Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sockets, in particular to a compatible female socket and an intelligent socket box. BACKGROUND

[0002] With the development of the fields of smart home, smart park, smart community, smart office, smart campus, smart old-age care, smart medical treatment and intelligent manufacturing, the intelligent trend of electrician products such as switches and sockets is obvious, and the market share is higher and higher. Compared with traditional mechanical products, the damage rate of intelligent products is higher, which brings inconvenience and cost of product maintenance to ordinary users.

[0003] At present, most of the traditional sockets on the market are mainly composed of pre-buried junction boxes and socket switch groups, and the wiring installation of the socket switch is carried out after pouring is completed. When the outer surface is damaged or the intelligent upgrading is carried out, only the whole can be replaced, and the replacement process is easy to cause electric leakage danger, waste the device, and also bring a large amount of environmental governance cost.

[0004] According to the investigation, at present, 37% of switches and sockets are changed 2-4 times (intelligent upgrading), and 93% of the reasons are that the position and function of the switch and socket cannot meet the requirements. 98% of the intelligent device systems have accepted more than 1 time of maintenance (63% of the intelligent systems have more than 3 times of heavy maintenance).

[0005] And when the switch and socket need to be replaced due to any of the above reasons, a large amount of labor cost is consumed.

[0006] At present, various types of socket switches on the market have obvious deficiencies in various functions, and there is no one in the entire industry that can meet the needs of most users, not to mention the rapid development of the Internet of Things and the increasing use of various terminal intelligent devices. Therefore, considering the increasing demand for sockets in the market, the application provides a compatible female socket and an intelligent socket box. SUMMARY

[0007] The application aims to solve the problems in the prior art and provides a compatible female socket and an intelligent socket box, which has a wide range of application scenarios and has the advantages of wiring-free and easy installation, is convenient for building a house with lower decoration cost, can meet the needs of different home decoration styles and easy adjustment of styles in the future market of the socket industry, and is welcomed by users. Therefore, the socket is also easy to market, has good market value, and is easy to market.

[0008] In order to achieve the above purpose, the application provides the following technical scheme:

[0009] A compatible female socket and an intelligent socket box, comprising:

[0010] The box body;

[0011] The adjusting unit is rotationally connected to the box body at the side facing the opening of the box body;

[0012] The interface unit is connected to various external plugs at one end facing the opening of the box body, and is connected to the wires at the other end;

[0013] The interface unit is slidingly connected to the box body, and is threadedly connected to the adjusting unit, so that the interface unit is driven to move by rotating the adjusting unit.

[0014] By the above structure, a high-adaptation socket with a wide range of application scenarios is formed, which has the advantages of free wiring and easy installation, and is convenient for building a house with lower decoration cost. In the future market of the plug-in industry, it is easier to meet the needs of different home decoration style designs and easy adjustment of style at any time, and can be deeply welcomed by users. Therefore, the socket is also very easy to market, and has good market value.

[0015] Preferably, the thread on the interface unit is arranged at the end of the interface unit close to the opening direction of the box body, and the thread is stopped before the edge of the end of the interface unit, so that the adjusting unit cannot be rotated out of the interface unit.

[0016] By the above structure, the rotation of the adjusting unit drives the interface unit to move to the extreme distance at the front and back ends without being separated from the adjusting unit, avoiding the operator from over-adjusting and causing the interface unit to fall. This design has two advantages. First, it limits the adjustment of the interface unit, avoiding the wires connected to the interface unit from being easily damaged due to excessive pulling, preventing the line from being disconnected to cause maintenance trouble, and preventing the line from being disconnected to cause the risk of easy electric shock around the socket, improving the safety of the socket in use. Second, it can prevent the socket from being reassembled into the socket due to the mistake in the adjustment operation.

[0017] Preferably, the adjusting unit is made of plastic.

[0018] By the above structure, the adjusting unit has a certain elasticity, which can slightly deform to ensure that the adjusting unit can be assembled with the interface unit, and the clamping part also has elasticity to be clamped into the mounting port, so that the entire adjusting unit and the interface unit can be assembled and installed into the protrusion and the limiting support. In addition, the adjusting unit made of plastic also has the advantages of insulation and low cost, which can improve the safety during adjustment operation and reduce the cost of the entire socket.

[0019] Preferably, the inner wall of the box body is further provided with a scale line arranged along the length direction of the adjusting unit.

[0020] Through the above structure, the user can refer to the scale line when adjusting the front end of the interface unit accurately, and it is easier to adapt to the plug specifications of the external intelligent terminal.

[0021] Preferably, the inner wall of the box body and the adjusting unit are both provided with an alignment line.

[0022] Through the above structure, the distance moved by the interface unit is measured according to the rotation of the adjusting unit by one revolution, so that the user can clearly know how many degrees to rotate to move the interface unit to the appropriate position.

[0023] Preferably, the outer surface of the adjusting unit is provided with an anti-slip structure.

[0024] Through the above structure, the user can avoid slipping when adjusting, and the operation experience is better.

[0025] Preferably, the anti-slip structure includes four annular concave parts uniformly distributed.

[0026] Through the above structure, it is convenient for the user to adjust, and the distance moved by the interface unit is fixed when rotating by one quarter, so that the user can accurately adjust the position of the interface unit.

[0027] Preferably, the bottom of the box body is provided with a mounting port, and the adjusting unit is rotationally connected to the mounting port.

[0028] Through the above structure, the mounting position is provided for the adjusting unit.

[0029] Preferably, the box body is provided with a limiting structure near the mounting port, the limiting structure is arranged in parallel along the moving direction of the interface unit, the outer surface of the interface unit is provided with a sliding groove, and the limiting structure is slidingly connected in the sliding groove.

[0030] Through the above structure, a path is provided for the movement of the interface unit in the box body.

[0031] Preferably, at least one end of the sliding groove does not penetrate the entire thread on the surface of the interface unit.

[0032] Through the above structure, the shell can be avoided from being completely slipped out to separate from the adjusting unit, the wire line connected to the interface unit can be avoided from being easily damaged due to excessive pulling, the line disconnection can be avoided to cause the trouble of maintenance, the risk of electric shock around the socket caused by line disconnection can be avoided, the safety of the socket during use is improved, and the trouble and danger of reassembling the interface unit into the socket caused by adjustment operation error can be avoided.

[0033] Preferably, the adjustment unit is rotatably connected to the inside edge of the mounting port.

[0034] The above structure integrates the entire interface unit into a very small space, comparable to traditional small and lightweight sockets. Compared to traditional sockets, it can achieve a small size like a traditional socket switch, thus adapting to various installation scenarios such as corners, bottom surfaces, and desktops. It also has the function of adjustable installation of smart terminal devices, which is not available in traditional sockets, thus having a very wide range of application scenarios.

[0035] Preferably, the radial section of the mounting port is U-shaped, and the adjustment unit is rotatably connected to the outer edge of the mounting port.

[0036] The above structure allows for greater space for the internal interface unit and adjustment unit to be installed. When the interface unit needs to be connected to a plug with more terminals, a housing with more first through holes is required. In this case, the diameter of the housing may be larger, thus enabling the installation of adjustment units that require more installation space.

[0037] Preferably, the adjustment unit is rotatably connected to the mounting port via a bearing.

[0038] The above structure reduces friction between the adjustment unit and the mounting port, making the adjustment more sensitive.

[0039] Preferably, the adjustment unit has a snap-fit ​​part on the end face opposite to the opening direction of the box body. The snap-fit ​​part fits with the edge of the mounting port, and the radial section of the snap-fit ​​part is L-shaped.

[0040] The above structure ensures that the adjustment unit can be easily installed into the mounting port, and that it is difficult for the adjustment unit to detach from the mounting port after installation. This provides a high degree of stability for the installation of the adjustment unit and the housing, preventing damage to the entire socket caused by excessive force when inserting or removing the external plug, and ensuring that the socket product has sufficient quality assurance.

[0041] Preferably, the bottom of the box body protrudes towards the opening of the box body, and the mounting port is located on the protrusion.

[0042] Preferably, a plurality of terminals are provided on the side of the protrusion away from the opening of the box, and a limit bracket is fixedly installed on the terminal, with the limit structure located on the central hole wall of the limit bracket.

[0043] The above structure not only provides the advantages of detachable and more robust installation of the limit bracket via screws, but also provides an installation position for the subsequent PCB board, making the installation of the PCB board with the limit bracket and the box more compact and secure, while occupying little space.

[0044] Preferably, the protrusion is tubular, the limiting structure is disposed on the central hole wall of the limiting bracket, the mounting port is disposed on the end face of the protrusion facing the opening of the box, and the diameter of the mounting port is smaller than the inner diameter of the protrusion.

[0045] Preferably, the protrusion is trumpet-shaped, and a limiting bracket is fixedly connected to the surface of the protrusion away from the adjustment unit. The limiting structure is provided on the central hole wall of the limiting bracket.

[0046] The above structure provides an installation location and movement path for the interface unit, integrating the entire interface unit into a very small space. It can rival traditional small and lightweight sockets. Compared with traditional sockets, it can achieve a small size like traditional socket switches, thus adapting to various installation scenarios, such as corners, bottom surfaces, and desktops. It also has the function of adjustable installation of smart terminal devices, which traditional sockets do not have. Therefore, it has a very wide range of application scenarios.

[0047] Preferably, the limiting bracket is bonded and fixed to the protrusion.

[0048] Preferably, the protruding surface has several screw holes, and the limiting bracket is fixed by screwing screws into the screw holes.

[0049] With the above structure, when the internal wiring of this socket generates a lot of heat or the heat from the external smart terminal diffuses into the box, it is not easy for the glue to melt due to heat, causing the limiting bracket to loosen or even detach.

[0050] Preferably, the surface of the protrusion facing the opposite direction of the box opening is provided with a plurality of buckle grooves, and the surface of the limiting bracket near the protrusion is provided with a buckle that cooperates with the buckle grooves.

[0051] With the above structure, the limit bracket and the protrusion can be detachably connected by inserting the buckle into the buckle. The advantage of this method is that the limit bracket can be installed quickly, which is faster than the threaded method and will not cause the glue to melt due to the socket being heated.

[0052] Preferably, the interface unit includes:

[0053] The outer casing has threads on its surface and is slidably connected to the adjustment unit. The outer casing has a first through hole inside.

[0054] A decorative cover is inserted into the end face of the outer shell facing the opening of the box. The decorative cover has a second through hole, which is aligned with the first through hole.

[0055] A conductive clip is fixedly connected inside the first through hole.

[0056] Preferably, the outer shell is provided with a limiting groove arranged along the moving direction of the interface unit, and the decorative cover is provided with an insert that matches the limiting groove.

[0057] With the above structure, the decorative cover can be installed by inserting the insert strip into the limiting groove on the end face of the outer shell. Therefore, this structural design makes the assembly operation very simple and convenient, and can save manpower.

[0058] Preferably, the limiting groove is located on the inner wall of the outer shell.

[0059] The above structure makes the outer shell more concise and aesthetically pleasing.

[0060] Preferably, it also includes a safety door, which is rotatably connected inside the decorative cover and located between the decorative cover and the outer shell. The safety door has several through holes aligned with the first through hole, and the safety door also has clearance holes through which the insert can pass.

[0061] The above structure allows the second through hole to be both covered and connected to the first through hole. Therefore, after the entire socket is installed and before any external plug is connected, external non-plug objects or living bodies cannot enter the decorative cover and outer shell. This can prevent accidental electric shock accidents caused by human contact, especially preventing children from sticking their fingers into the socket. It can also reduce the entry of dust, impurities and other foreign objects that may affect the power supply efficiency of the socket, and reduce the difficulty of wiping and maintenance. This improves the usability and safety of the socket and reduces maintenance costs.

[0062] Preferably, the decorative cover has a baffle at one end near the safety door and on one side of the second through hole, and the baffle is located inside the through hole when the safety door is installed on the decorative cover; the safety door has a relief groove on one side wall of the through hole that can accommodate the baffle, and the relief groove is inclined or arc-shaped.

[0063] With the above structure, when an external plug is connected, the plug moves directly along the surface of the clearance groove, thereby driving the safety door to rotate, so that the first through hole and the second through hole are connected to allow the external plug to be connected.

[0064] Preferably, the safety door is further provided with a return spring, one end of which is connected to the safety door and the other end of which is connected to the outer shell or decorative cover;

[0065] The elasticity of the reset spring ensures that the safety door remains in a state of blocking the first and second through holes when no external plug is inserted into the interface unit.

[0066] The above structure enables the first and second through holes to be automatically blocked when the plug is unplugged and when no external plug is connected to the socket.

[0067] Preferably, the safety door has an arc-shaped receiving groove on the end face near the outer shell, the reset spring is installed in the receiving groove, and the outer shell has a protrusion that can extend into the receiving groove on the end face near the safety door.

[0068] With the above structure, this design not only provides sufficient installation space for the reset spring in a very narrow space, ensuring that this technical solution is a small and lightweight socket, but also gives the reset spring enough deformable space and reaction force, making the user's operation simpler and more convenient, and also very durable.

[0069] Preferably, the two ends of the reset spring abut against the end of the receiving groove and the protrusion respectively. The reset spring remains in a compressed state at any time after installation, and the direction of the reaction force of the reset spring is the rotation direction that drives the safety door to block the first through hole.

[0070] With the above structure, this design not only provides sufficient installation space for the reset spring in a very narrow space, ensuring that this technical solution is a small and lightweight socket, but also gives the reset spring enough deformable space and reaction force, making the user's operation simpler and more convenient, and also very durable.

[0071] Preferably, the two ends of the reset spring are fixedly connected to the end of the receiving groove and the protrusion, respectively. The reset spring remains in a stretched state at any time after installation, and the direction of the reaction force of the reset spring is the rotation direction that drives the safety door to block the first through hole.

[0072] The above structure allows the return spring to also be a tension spring. While the installation of the rotating door is slightly more complicated than that of the compression method, it allows for a wider variety of spring cross-sectional shapes to be selected for the return spring, and also allows for more design options for the receiving groove, such as rectangular cross-section tension springs and receiving grooves.

[0073] Preferably, it further includes a wiring unit, which is fixedly connected to the conductive clamp; the wiring unit includes:

[0074] A wiring frame, wherein the wiring frame is inserted into the first through hole, and the conductive clip is fixedly connected inside the wiring frame;

[0075] An end cap is fixedly connected to the end of the outer shell away from the decorative cover, and the end cap is provided with a plurality of third through holes aligned with the first through hole;

[0076] The third through hole is used for wire connection.

[0077] The above structure allows the external wires and the conductive clamp to be firmly fixed together, thereby completing the electrical connection.

[0078] Preferably, the outer edge of the end cap is provided with a hook, and the outer surface of the outer shell near the end cap is provided with a hook hole.

[0079] The above structure makes it easy and secure to assemble the end cap and the outer shell, preventing them from easily coming loose. Moreover, the assembly has a limiting function, preventing radial sliding of the end cap after installation, which could cause the line to be squeezed, thus preventing the power supply efficiency of the line from being affected and preventing the line from aging faster.

[0080] Preferably, the outer surface of the housing near the end cover is provided with a mounting hole through which the first through hole can pass, the wiring frame is provided with a positioning hole near the mounting hole, the conductive clip is U-shaped near the end cover, and a screw is screwed into the mounting hole to connect the circuit.

[0081] With the above structure, any number of wires can be connected to this socket, making it compatible with plugs of any specification and model, and thus compatible with the assembly of any smart terminal. This ensures that the socket has a wide range of applications, and the wiring and assembly operations are very simple and convenient.

[0082] Preferably, it also includes a pre-embedded box, which is pre-embedded in the building and the box body is detachably connected to the pre-embedded part.

[0083] The above structure facilitates both the installation and disassembly of this common socket. Therefore, for existing pre-embedded boxes on the market, as long as they conform to the design concept of detachable sockets, this common socket can be directly assembled with the existing pre-embedded boxes. Thus, for buildings where sockets have already been installed, it is not necessary to install this pre-embedded box separately, further improving the adaptability of this common socket.

[0084] Preferably, the surface of the pre-embedded box is provided with a plurality of wire-passing holes, and a detachable baffle is provided inside the wire-passing holes.

[0085] The above structure not only helps to prevent mortar from seeping into the pre-embedded box when it is embedded in the wall in advance, but also allows the external wires to be pulled into the pre-embedded box by simply knocking off the removable cover during subsequent socket wiring operations. When this socket is used in conjunction with a smart terminal, it can also serve as a heat dissipation channel.

[0086] Preferably, the inner wall of the pre-embedded box is provided with a plurality of limiting protrusions, the limiting protrusions are inclined toward the side facing the opening of the pre-embedded box, and the box body is provided with a shaped hole that cooperates with the limiting protrusions.

[0087] The above structure allows the box to be inserted into the pre-embedded box and locked into the shaped hole, preventing the box from automatically coming out after installation.

[0088] Preferably, both the pre-embedded box and the edge of the box body are provided with bent edges.

[0089] The above structure provides a certain limiting effect for the installation of the box body into the pre-embedded box and the pre-embedded box into the building, preventing the surface of the pre-embedded box from embedding into the wall during the pouring process. It also provides a certain limiting effect for the subsequent smart terminal, avoiding damage to the socket due to excessive force when plugging and unplugging the plug.

[0090] Preferably, the bent edge is provided with a magnetic absorbing piece.

[0091] The above structure allows the installation box to automatically slide into the pre-embedded box when it is installed, and maintains attraction when the pre-embedded box and the magnetic plate on the box come close together. This can improve the firmness of the box and the pre-embedded box to a certain extent. In the event of an earthquake or other reasons that cause the box to be subjected to a certain force and tend to fall out, it can prevent the box from falling out or stretching the lines, thus avoiding safety situations such as electric shock or injury to people in the event of an accident.

[0092] The present invention also provides the following technical solutions:

[0093] A smart junction box includes a compatible female socket as described above, and also includes a smart male socket, the smart male socket comprising:

[0094] A male plug, which is inserted into the interface unit to enable electrical connection;

[0095] The panel includes, but is not limited to, terminals such as push-button switches, displays, touch screens, and smart switches.

[0096] Compared with the prior art, the beneficial effects of this invention are as follows: it forms a highly adaptable socket with a wide range of application scenarios, and also has the advantages of being wire-free and easy to install, making it easier to build houses with lower decoration costs. In the future market of the socket industry, it is easier to meet the needs of different home decoration styles and the need to adjust the style at any time, which can be well received by users. Therefore, this socket is also very easy to promote in the market and has good market value. Attached Figure Description

Detailed Implementation

[0116] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0117] Example 1:

[0118] Please see Figures 1-3 The present invention provides the following technical solution: a compatible female socket, comprising:

[0119] Box 1;

[0120] Adjustment unit 2 is rotatably connected to the side of the box 1 facing the opening of the box 1;

[0121] Interface unit 3, one end of interface unit 3 facing the opening of box 1 is used for connecting various external plugs, and the other end of interface unit 3 is connected to various wires;

[0122] Interface unit 3 is slidably connected to housing 1, and interface unit 3 is threadedly engaged with adjustment unit 2. The interface unit 3 is driven to move by rotating adjustment unit 2.

[0123] As an optional embodiment of the present invention, the interface unit 3 integrates a power supply wire and can connect to plugs of any specification. Therefore, it is applicable to most specifications and standards of plug access, such as three-prong, two-prong, USB, Type-C, and other simple or very complex plugs. It can be used directly as a power plug or as a data interface, directly connecting to various electrical appliances for power supply or data transmission. It can also be used as a mounting base and power socket for various switch panels 51, with a very wide range of applications. When the adjustment unit 2 rotates, since the interface unit 3 and the adjustment unit 2 are both slidably connected and threadedly engaged, the interface unit 3 can only be driven by the rotation of the adjustment unit 2. The sliding mechanism allows the interface unit 3 to move within the housing 1, accommodating both flexible connector plugs and direct connectors designed for different locations. This avoids the problem of various smart terminals being unable to install different plugs due to variations in plug design specifications and sizes. The housing 1 allows the socket to be installed in the wall along with the pre-embedded box 42 as a wall socket, or on the floor as a floor socket, or on furniture such as desktops or counters. Alternatively, the socket can be installed directly in these scenarios without the pre-embedded box 42. Furthermore, protective structures such as moisture-proof and waterproof features can be designed directly on the socket to extend its application to even more scenarios.

[0124] In this embodiment, an anti-electric shock sticker can also be affixed to the surface of the box 1. If the circuit is damaged or other reasons cause the box 1 to be electrified, it can prevent electric shock caused by touching the box 1 during use, thereby improving safety.

[0125] Various installation structures can be designed on the box 1, such as designing lugs, drilling holes on the box 1 and then inserting screws 11, so that the socket can have different installation and fixing methods.

[0126] Box 1 can be connected directly during the water and electricity installation of the building, either alone or together with the pre-embedded box 42. This completes the common infrastructure in one go, so that the sockets are installed in the unfinished house before moving in, making the overall appearance of the unfinished house more beautiful. Therefore, after moving in, users only need to install different public sockets according to their own needs. It is very simple and convenient to use. Therefore, users do not need to install sockets themselves or hire electricians during the decoration, which can save users a lot of decoration costs.

[0127] Based on a survey of the costs of upgrading traditional sockets to smart technology, the costs of on-site installation and debugging by technicians, and the costs of requiring additional chargers for traditional sockets, the survey results are shown in Tables 1-3 below:

[0128] Table 1: Cost Statistics for Upgrading Traditional Switches and Sockets to Intelligent Systems

[0129]

[0130] Table 2: Survey statistics on the cost allocation of on-site upgrade and debugging by technicians, and the cost of additional chargers required for traditional sockets:

[0131]

[0132] Table 3: Cost Statistics for Upgrading Traditional Switches and Sockets to Intelligent Systems

[0133]

[0134] Table 4: Statistical analysis of the unit cost of this socket:

[0135]

[0136] Based on the survey results in Tables 1-3 above regarding the costs of upgrading traditional sockets to smart technology, the costs of on-site installation and debugging, and the costs of requiring additional chargers for traditional sockets, combined with the cost analysis of a single socket in Table 4, compared to traditional sockets, taking a single household as an example, the cost of upgrading traditional switches and sockets to smart technology involves 2-4 modifications due to inadequate location and functionality. Including the costs of on-site installation and debugging, and the costs of additional chargers for traditional sockets, and excluding material waste and environmental remediation costs associated with traditional upgrades, the comprehensive cost of upgrading traditional junction boxes to smart technology reaches 55 yuan per unit, exceeding the cost of a smart junction box. The comprehensive cost of a smart junction box, which completes the upgrade of common infrastructure in one go, is 16 yuan lower per unit than the comprehensive cost of upgrading traditional junction boxes to smart technology. After applying the smart junction box, the common base brings hardware cost savings (secondary cost savings) for smart terminals, saving up to 150 yuan per terminal per household (based on a three-bedroom, one-living room apartment), totaling 5285 yuan in savings. With 430 million households nationwide, and assuming a cumulative installation rate of 30% over the next ten years, this translates to a total cost saving of 680 billion yuan for all households. The smart junction box can also be directly applied to office and commercial environments; a single building (based on 10,000 smart terminals) is expected to save 1.66 million yuan per building.

[0137] The above structure creates a highly adaptable socket with a wide range of applications. It also has the advantages of being wire-free and easy to install, making it easier to build houses with lower decoration costs. In the future market of the socket industry, it is easier to meet the needs of different home decoration styles and the need to adjust the style at any time, which will make it popular with users. Therefore, this socket is also very easy to promote in the market and has good market value.

[0138] Example 2:

[0139] Please see Figures 2-4The present invention provides the following technical solution: a compatible female socket, comprising:

[0140] Box 1, Box 1 protrudes 13 in the direction of the opening of Box 1, the protrusion 13 is provided with an installation port 8, the protrusion 13 is flared, and a limit bracket 15 is also attached to the surface of the protrusion 13 away from the adjustment unit 2, and a limit structure 9 is provided on the central hole wall of the limit bracket 15.

[0141] Adjustment unit 2, the end face of adjustment unit 2 opposite to the opening direction of box 1 is provided with a snap-fit ​​part 12, and the radial section of snap-fit ​​part 12 is L-shaped, and snap-fit ​​part 12 is rotatably connected to the inner side of the edge of the mounting port 8.

[0142] Interface unit 3 has one end facing the opening of box 1 for connecting various external plugs, and the other end of interface unit 3 for connecting wires. The outer surface of interface unit 3 is provided with a sliding groove 10 along the moving direction of interface unit 3, and the limiting structure 9 is slidably connected in the sliding groove 10. Interface unit 3 is also threadedly engaged with adjustment unit 2. The thread on interface unit 3 is provided at the end of the outer surface of interface unit 3 near the opening of box 1. The interface unit 3 is driven to move by rotating adjustment unit 2.

[0143] The thread stops before the end edge of the interface unit 3, preventing the adjustment unit 2 from being unscrewed from the interface unit 3. The adjustment unit 2 is made of plastic, and at least one end of the groove 10 does not penetrate the thread on the entire surface of the interface unit 3.

[0144] As an optional embodiment of the present invention, the protrusion 13 and the limiting bracket 15 provide the installation position and movement path for the interface unit 3, integrating the entire interface unit 3 into a very small space. This is comparable to traditional small and lightweight sockets. Compared to traditional sockets, it can achieve a small size like a traditional socket switch, thus adapting to various installation scenarios such as corners, bottom surfaces, and desktops. It also has the function of adjustable installation of smart terminal devices, which is not available in traditional sockets, thus having a very wide range of application scenarios. By adjusting the threaded engagement between the adjustment unit 2 and the interface unit 3 and the sliding engagement between the interface unit 3 and the housing 1, the interface unit 3 can be moved without causing damage. The rotation of interface unit 3 prevents wire tangling at the terminals, thus avoiding malfunction and ensuring proper movement. It also prevents external plugs from being unable to connect properly to the socket if the external plug is rotated. This design creates a highly adaptable common female connector, ensuring a wide range of applications. The major diameter of the external thread of interface unit 3 does not exceed its outer diameter. Preferably, the major diameter of the external thread is equal to the outer diameter. This design ensures that the entire interface unit 3, along with the protrusion 13, the limiting bracket 15, and the adjustment unit 2, are integrated seamlessly. The smaller gap between them ensures a closer fit between the limiting bracket 15 and the slide groove 10, and also allows the overall size of the socket to be designed to be small enough to rival traditional sockets. The threaded design at both ends prevents the interface unit 3 from disengaging from the adjusting unit 2 when it reaches its maximum front and rear distances, thus preventing it from falling off due to over-adjustment. This design also limits the adjustment of the interface unit 3, preventing excessive pulling and damage to the wires connected to it. This avoids both the inconvenience of repairs due to wire breakage and the risk of electric shock around the socket caused by a broken wire, improving the safety of the socket during use. Secondly, it eliminates the hassle and danger of having to reassemble the interface unit 3 into the socket due to adjustment errors. The adjustment unit 2, made of plastic, has a certain degree of elasticity. When assembled onto the threads that stop at both ends, it can undergo slight elastic deformation to ensure that the adjustment unit 2 can be assembled with the interface unit 3. At the same time, it also ensures that the snap-fit ​​part 12 is elastic enough to snap into the mounting port 8, so that the entire adjustment unit 2 and interface unit 3 can be installed into the protrusion 13 and the limiting bracket 15 after assembly. Furthermore, the adjustment unit 2 made of plastic also has the advantages of insulation and low cost, which can improve the safety of adjustment operations and reduce the overall cost of the socket.

[0145] In this embodiment:

[0146] The inner diameter of the front end of the adjusting unit 2 and the inner diameter of the snap-fit ​​part 12 should not be lower than the major diameter of the internal thread on the adjusting unit 2, so as to ensure that when the internal thread on the adjusting unit 2 moves to the middle of the external thread on the interface unit 3, neither the front end of the adjusting unit 2 nor the snap-fit ​​part 12 will obstruct the movement of the interface unit 3.

[0147] In order to ensure that the integrated adjustment unit 2 and interface unit 3 can be installed on the protrusion 13, the inner diameter of the snap-fit ​​part 12 should be larger than the major diameter of the internal thread of the adjustment unit 2, so as to ensure that the snap-fit ​​part 12 has deformable space and thus ensure that the snap-fit ​​part 12 can be snapped into the mounting port 8.

[0148] The snap-fit ​​part 12 can be designed as a right trapezoid. This ensures that the snap-fit ​​part 12 can be easily installed into the mounting port 8, and also makes it difficult for the adjustment unit 2 to detach from the mounting port 8 after it is installed. This makes the installation of the adjustment unit 2 and the housing 1 more secure, preventing the adjustment unit 2 from detaching from the mounting port 8 due to excessive force when inserting or removing the external plug, which would damage the entire socket and ensure that the socket product has sufficient quality assurance.

[0149] For the adjustment unit 2, the internal thread and the outer layer of the adjustment unit 2 can be made separately. Specifically, it can be set as an elastic ring component with internal thread and an outer ring without internal thread. During assembly, the elastic ring is first installed on the interface unit 3 to achieve thread engagement. Then, glue or double-sided tape is applied to the axial surface of the elastic ring. Then, the outer ring is put on the elastic ring to form the whole adjustment unit 2. Then, the adjustment unit 2 is gently pushed to make the snap-fit ​​part 12 snap-fit ​​with the mounting port 8. This design method is much easier than making the entire adjustment unit 2 elastically deform. Although the process is more complicated, it is easier to install.

[0150] For the groove 10, which at least one end does not penetrate the thread on the entire surface of the interface unit 3, if the diameter of the decorative cover 20 is larger than the major diameter of the thread of the adjustment unit 2, it is preferable that the rear end of the outer shell 19 does not penetrate. This can prevent the outer shell 19 from completely detaching from the adjustment unit 2, and prevent the wires connected to the interface unit 3 from being excessively pulled and easily damaged. This not only prevents the trouble of maintenance caused by wire breakage, but also prevents the danger of electric shock around the socket due to wire breakage, thus improving the safety of the socket during use. Secondly, it can prevent the socket from having the trouble and danger of needing to reassemble the interface unit 3 into the socket due to adjustment operation errors.

[0151] The above structure creates a compact socket that is low-cost, can be manufactured in a small and lightweight manner, can be installed in a wide range of application scenarios, is highly adaptable, and is simple, convenient, safe, maintenance-free, and easy to disassemble and assemble.

[0152] Example 3:

[0153] Please see Figures 2-12 The present invention provides the following technical solution: a compatible female socket, comprising a housing 1, an adjustment unit 2 and an interface unit 3; the adjustment unit 2 is rotatably connected to the side of the housing 1 facing the opening of the housing 1;

[0154] Interface unit 3 includes a housing 19 and a decorative cover 20; the surface of housing 19 is provided with threads that mate with adjustment unit 2, housing 19 is slidably connected to adjustment unit 2, and interface unit 3 is driven to move by rotating adjustment unit 2;

[0155] The inner wall of the outer shell 19 is provided with a limiting groove 24 arranged along the moving direction of the interface unit 3. The decorative cover 20 is provided with an insert 25 that matches the limiting groove 24 on the side near the outer shell 19, so that the decorative cover 20 can be inserted into the end face of the outer shell 19 facing the opening of the box 1. The outer shell 19 is provided with a first through hole 21, and a conductive clip 23 for connecting various wires is fixedly connected in the first through hole 21. The decorative cover 20 is provided with a second through hole 22 for connecting various external plugs, and the second through hole 22 is aligned with the first through hole 21.

[0156] A safety door 26 is rotatably connected inside the decorative cover 20 and between the decorative cover 20 and the outer shell 19. The safety door 26 has several through holes 27 aligned with the first through hole 21, and also has clearance holes 28 for the insertion strip 25 to pass through. A baffle 29 is provided on one end of the decorative cover 20 near the safety door 26 and on the side of the second through hole 22. When the safety door 26 is installed on the decorative cover 20, the baffle 29 is located inside the through holes 27. A clearance groove 30 is provided on the side wall of the safety door 26 on the side of the through hole 27 to accommodate the baffle 29. The clearance groove 30 is inclined or arc-shaped.

[0157] The safety door 26 has an arc-shaped receiving groove 32 on the end face near the outer casing 19. A return spring 31 is provided in the receiving groove 32. The outer casing 19 has a protrusion 33 that can extend into the receiving groove 32 on the end face near the safety door 26. The two ends of the return spring 31 abut against the end of the receiving groove 32 and the protrusion 33, respectively. The return spring 31 is kept in a compressed state at any time after installation, and the direction of the reaction force of the return spring 31 is the direction of rotation that drives the safety door 26 to block the first through hole 21. The elasticity of the return spring 31 ensures that the safety door 26 blocks the first through hole 21 and the second through hole 22 when no external plug is inserted into the interface unit 3.

[0158] As an optional embodiment of the present invention, a basic socket core structure is formed by the decorative cover 20, the outer shell 19, and the wire clamp. During assembly, simply insert the wire clamp into the first through hole 21 on the outer shell 19, and then insert the insert strip 25 into the limiting groove 24 on the end face of the outer shell 19 to install the decorative cover 20. Therefore, this structural design makes assembly very simple and convenient, saving manpower. Furthermore, when designing corresponding assembly equipment for this technical solution, the relatively simple appearance of each component and the simple assembly process make it easier to design corresponding assembly equipment, which helps to accelerate the market promotion of this socket product. This makes the socket product more likely to meet market demands compared to traditional sockets, further accelerating the promotion of the Internet of Things (IoT) in the market, thereby speeding up the popularization of advanced technologies such as IoT in smart parks, smart communities, smart offices, smart campuses, smart elderly care, smart healthcare, and intelligent manufacturing, as well as promoting socio-economic development. Through the rotation of the safety door 26 between the outer shell 19 and the decorative cover 20, the second through hole 22 and the first through hole 21 can be both blocked and connected. Therefore, in the overall design of this socket… After all installation is complete and before any external plug is connected, the decorative cover 20 and the outer casing 19 are prevented from being entered by non-plug objects or living persons. This prevents accidental electric shock accidents, especially preventing children from sticking their fingers into the socket. It also reduces the entry of dust, impurities, and other foreign objects that could affect the power supply efficiency of the socket, and reduces the difficulty of wiping and maintenance, thereby improving the usability and safety of the socket and reducing maintenance costs. Furthermore, a reset spring 31 is installed inside the safety door 26 and the outer casing 19, ensuring that after the plug is unplugged and the safety door 26 is not in use, the socket remains closed. When an external plug is connected, it automatically blocks the first through hole 21 and the second through hole 22. When an external plug is connected, the plug can move directly along the surface of the clearance groove 30 to drive the safety door 26 to rotate, so that the first through hole 21 and the second through hole 22 can be connected to allow the external plug to be connected. This structural design not only gives the return spring 31 enough installation space in a very narrow space, ensuring that this technical solution is a small and lightweight socket, but also gives the return spring 31 enough deformable space and reaction force, making the user's operation simpler and more convenient, and also very durable.

[0159] In this embodiment, the outer shell 19, safety door 26 and decorative cover 20 can all be made of plastic material, which is not only low in weight and cost, but also very convenient for mass production and molding. It also has good insulation to ensure that users will not accidentally touch the power source and cause safety accidents.

[0160] The insert 25 on the decorative cover 20 and the limiting groove 24 in the outer shell 19 also have anti-detachment designs, such as elastic damping, interference fit, and snap-fit ​​design, to ensure that the outer shell 19 and the decorative cover 20 are very firmly installed after installation. No matter how the outer shell 19 and the decorative cover 20 are adjusted, there will be no loosening. This prevents the safety door 26 from falling off due to the decorative cover 20 becoming loose or even falling off, thus preventing the entire core structure of the socket from falling apart and ensuring the effective adjustability of the socket. In addition, this design improves the sealing of the safety door 26, ensuring that external impurities cannot enter, which has significant beneficial effects.

[0161] After installation, the safety door 26 is in close contact with the end face of the outer shell 19 and the inner wall of the decorative cover 20 at both ends, thus completely blocking the connection between the first through hole 21 and the second through hole 22. This ensures that external dust, impurities, and moisture cannot enter the interior of the outer shell 19 through the second through hole 22, preventing the socket from being affected by dust, impurities, and moisture, which could accelerate aging or even cause short circuits and damage. This further improves the durability of this application and extends the service life of the socket, greatly reducing the cost of maintenance and repair for users and increasing the popularity of this socket in the market.

[0162] The number of first through holes 21 on the outer casing 19 and second through holes 22 on the decorative cover 20 are equal and not less than one each. They can be distributed in a ring or designed according to other plug standards. Each wire clamp can connect to the neutral wire, live wire, ground wire, or wires connected to any different functional modules. The shape of all through holes can be of any specification so that various styles of wire clamps can be installed in the outer casing 19, thereby allowing plugs of any specification and shape, such as flat or cylindrical, to be directly connected to this socket, ensuring that this socket has sufficiently high compatibility and a wide range of application scenarios.

[0163] The above structure creates a highly compatible socket that is small in size, highly safe, easy to maintain, and more durable.

[0164] Example 4:

[0165] Please see Figures 1-12 The present invention provides the following technical solution: a compatible female socket, comprising a housing 1, an adjustment unit 2, and an interface unit 3; the interface unit 3 includes a housing 19, a decorative cover 20, and a wiring unit 34; the adjustment unit 2 is rotatably connected to the side of the housing 1 facing the opening of the housing 1, the surface of the housing 19 is provided with threads that cooperate with the adjustment unit 2, and the housing 19 is slidably connected inside the adjustment unit 2, and the interface unit 3 is moved by rotating the adjustment unit 2; the wiring unit 34 includes a wiring frame 35 and an end cover 36.

[0166] The outer casing 19 has a first through hole 21 inside, and the wiring frame 35 is inserted into the first through hole 21. The wiring frame 35 is fixedly connected with a conductive clip 23 for connecting various wires. The decorative cover 20 is inserted into the end face of the outer casing 19 facing the opening of the box 1. The decorative cover 20 has a second through hole 22 for connecting various external plugs. The second through hole 22 is aligned with the first through hole 21.

[0167] The end cap 36 is fixedly connected to the end of the outer shell 19 away from the decorative cover 20. The end cap 36 is provided with several third through holes 37 aligned with the first through hole 21. The third through holes 37 are used for wire access. The outer surface of the outer shell 19 near the end cap 36 is provided with a mounting hole 40 that can pass through the first through hole 21. The wiring frame 35 is provided with a positioning hole 41 near the mounting hole 40. The part of the conductive clip 23 near the end cap 36 is U-shaped. The screw 11 is screwed into the mounting hole 40 to realize the connection of the circuit.

[0168] The outer edge of the end cap 36 is provided with a hook 38, and the outer surface of the outer shell 19 near the end cap 36 is provided with a hook hole 39.

[0169] As an optional embodiment of the present invention, the conductive clip 23 is inserted into the wiring frame 35, and then the wiring frame 35 and the conductive clip 23 are inserted together into the first through hole 21. The external wire passes through the third through hole 37, through the end cover 36, and is placed in the conductive clip 23. The screw 11 is screwed into the mounting hole 40 and the positioning hole 41, so that the external wire and the conductive clip 23 are tightly fixed together, thereby completing the electrical connection. This design allows any number of wires to be connected to this socket, so that this socket can be adapted to plugs of any specification and model, and thus can be adapted to any smart terminal. The assembly of the end caps ensures that the socket has a wide range of applications, and the wiring assembly operation is very simple and convenient. The end cap 36 is snapped into the hook hole 39 by the hook 38, which simultaneously aligns the third through hole 37 with the first through hole 21 and fixes the end cap 36 to the outer shell 19. This assembly method makes the assembly of the end cap 36 and the outer shell 19 both convenient and firm, and it is not easy to loosen. Moreover, it has a limiting function after assembly, which prevents the radial sliding of the end cap 36 after installation from causing the wires to be squeezed, thus preventing the power supply efficiency of the line from being affected and preventing the aging of the line from being accelerated.

[0170] In this embodiment:

[0171] The end cap 36 is also provided with a boss that mates with the first through hole 21 on the side near the outer shell 19. The third through hole 37 is located inside the boss, which can further ensure that the connection between the end cap 36 and the outer shell 19 is tighter and more secure, so that there is absolutely no radial or axial movement between the end cap 36 and the outer shell 19 after installation.

[0172] The latch 38 on the end cap 36 can also be accessed from inside the housing 19 to connect with the hook hole 39 on the housing 19.

[0173] The above structure creates a socket that is simple and convenient to connect and assemble, and can be adapted to any type and model of plug after assembly, thus having a wide range of applications.

[0174] Example 5:

[0175] Please see Figure 1 The present invention provides the following technical solution: a compatible female socket, comprising:

[0176] Box 1;

[0177] Adjustment unit 2 is rotatably connected to the side of the box 1 facing the opening of the box 1;

[0178] Interface unit 3, one end of interface unit 3 facing the opening of box 1 is used for connecting various external plugs, and the other end of interface unit 3 is connected to various wires;

[0179] Embedded box 42 is pre-embedded in the building, and the box body 1 is detachably connected to the embedded part;

[0180] Interface unit 3 is slidably connected to housing 1, and interface unit 3 is threadedly engaged with adjustment unit 2. The interface unit 3 is driven to move by rotating adjustment unit 2.

[0181] As an optional embodiment of the present invention, the pre-installed box 42 is pre-installed on the building wall, which is consistent with most current concealed boxes that pre-place junction boxes, in order to facilitate the subsequent wiring and installation of the socket. The significance of the detachable connection between the box body 1 and the pre-installed box 42 is that it facilitates both the installation and disassembly of this common socket. Therefore, for some pre-installed boxes 42 currently available on the market, as long as they conform to the design concept of detachable sockets, this common socket can be directly assembled with the existing pre-installed box 42. Thus, for buildings where sockets have already been installed, it is not necessary to install this pre-installed box 42 separately, further improving the adaptability of this common socket.

[0182] In this embodiment, the axial section of the embedded box 42 can be a circle, a square, a triangle or a polygon. In this technical solution, a square is preferred, but the above shape and specifications can be adjusted according to actual needs.

[0183] Example 6:

[0184] Please see Figures 1-2 The present invention provides the following technical solution: a compatible female socket, comprising:

[0185] Box 1;

[0186] Adjustment unit 2 is rotatably connected to the side of the box 1 facing the opening of the box 1;

[0187] Interface unit 3, one end of interface unit 3 facing the opening of box 1 is used for connecting various external plugs, and the other end of interface unit 3 is connected to various wires; interface unit 3 is slidably connected to box 1, and interface unit 3 is threadedly engaged with adjustment unit 2, and interface unit 3 is driven to move by rotating adjustment unit 2.

[0188] Embedded box 42 is pre-embedded in the building, and the box body 1 is detachably connected to the embedded part;

[0189] The surface of the embedded box 42 is provided with several wire-passing holes 43, and a detachable baffle 44 is provided inside the wire-passing holes 43; the inner wall of the embedded box 42 is provided with several limiting protrusions 45, and the limiting protrusions 45 are inclined towards the opening direction of the embedded box 42; the box body 1 is provided with a shaped hole 46 that mates with the limiting protrusions 45; both the embedded box 42 and the box body 1 are provided with bent edges 47; magnetic suction pieces 48 are provided on the bent edges 47.

[0190] As an optional embodiment of the present invention, there are only a few connection points between the removable baffle 44 on the pre-embedded box 42 and the pre-embedded box 42, and the gap between the removable baffle 44 and the pre-embedded box 42 is also small. During manufacturing, it can be easily removed by gently tapping it off during installation. This design not only helps prevent mortar from seeping into the pre-embedded box 42 when it is pre-embedded in the wall, but also allows for easy wiring of the socket by simply tapping off the removable baffle 44 to allow external wires to be pulled into the pre-embedded box 42 through the wire pass 43. When this socket is used in conjunction with a smart terminal, it can also serve as a heat dissipation channel; the limiting protrusion 45 is on the box body 1. When pushed into the pre-embedded box 42, it is inserted into the shaped hole 46, which prevents the box body 1 from automatically falling out after installation; the magnetic suction piece 48 allows the box body 1 to automatically slide into the pre-embedded box 42 when it is installed, and maintains attraction when the pre-embedded box 42 and the magnetic suction piece 48 on the box body 1 are close together, which can improve the firmness of the box body 1 and the pre-embedded box 42 to a certain extent. When the box body 1 is subjected to a certain force due to earthquake or other reasons, and the box body 1 tends to fall out or stretch the line, it can prevent the box body 1 from falling out or stretching the line, thus avoiding safety situations such as electric shock or injury to people in case of accidents or accidents.

[0191] In this embodiment, the threading port 43 and the non-removable baffle 44 can be designed in different shapes and quantities, and this technical solution does not make specific limitations on them.

[0192] The shape, quantity, and specific design location of the limiting protrusions 45 are not specifically limited in this technical solution;

[0193] The bent edge 47 provides a certain limiting function for the installation of the box body 1 into the embedded box 42 and the installation of the embedded box 42 into the building, preventing the surface of the embedded box 42 from embedding into the wall during the pouring of the concrete. It also provides a certain limiting function for the subsequent smart terminal, avoiding damage to the socket due to excessive force when plugging and unplugging the plug.

[0194] The magnetic absorbing sheet 48 can be specifically set in the pre-embedded box 42 and / or the box body 1. This technical solution does not specifically limit the number or specifications of the magnetic absorbing sheets 48 set in any component.

[0195] The above structure creates a socket that is convenient for on-site construction and installation as well as for subsequent wiring. Using this socket greatly facilitates electrical work, ensuring that the socket does not delay the delivery of unfinished houses. This makes it popular with construction companies, making the socket product very easy to market and promote.

[0196] Example 7:

[0197] This invention provides the following technical solution: a compatible female socket, comprising:

[0198] Box 1, with a protrusion 13 in the direction of the opening of box 1, and an installation port 8 provided on the protrusion 13;

[0199] Adjustment unit 2 is rotatably connected to the inside edge of the mounting port 8 via a bearing;

[0200] Interface unit 3, one end of interface unit 3 facing the opening of box 1 is used for connecting various external plugs, and the other end of interface unit 3 is connected to various wires;

[0201] Interface unit 3 is slidably connected to housing 1, and interface unit 3 is threadedly engaged with adjustment unit 2. The interface unit 3 is driven to move by rotating adjustment unit 2.

[0202] As an optional embodiment of the present invention, the bearing can reduce the friction between the adjustment unit 2 and the mounting port 8, making the adjustment more sensitive.

[0203] In this embodiment, the protrusion 13 can be either tubular or trumpet-shaped; this technical solution does not impose any specific limitations.

[0204] The mounting port 8 needs to be designed to prevent detachment from the bearing. Specific methods include, but are not limited to, designing the edge of the snap-fit ​​part 12 to cover the entire end face of the bearing, or using adhesive or other methods to directly fix the outer and inner rings of the bearing to the connected parts. This ensures that the installation of the adjustment unit 2 and the housing 1 is highly secure, preventing the adjustment unit 2 from detaching from the mounting port 8 due to excessive force when inserting or removing the external plug, which could damage the entire socket and ensure that the socket product has sufficient quality assurance.

[0205] Example 8:

[0206] This invention provides the following technical solution: a compatible female socket, comprising:

[0207] Box 1, with a protrusion 13 in the direction of the opening of box 1, and an installation port 8 provided on the protrusion 13;

[0208] Adjustment unit 2 is rotatably connected to the outer edge of the mounting port 8;

[0209] Interface unit 3, one end of interface unit 3 facing the opening of box 1 is used for connecting various external plugs, and the other end of interface unit 3 is connected to various wires;

[0210] Interface unit 3 is slidably connected to housing 1, and interface unit 3 is threadedly engaged with adjustment unit 2. The interface unit 3 is driven to move by rotating adjustment unit 2.

[0211] As an optional embodiment of the present invention, the adjustment unit 2 can also be installed on the outside of the mounting port 8, with the mounting port 8 protruding towards the center line of the box 1 and recessed into the inner wall of the box 1, or the edge of the mounting port 8 protruding directly outward at the edge of the protrusion 13. The snap-fit ​​part 12 can be snapped into the mounting port 8 from the outside. The advantage of this design is that the internal interface unit 3 has more space to install the adjustment unit 2. When the interface unit 3 needs to be connected to a plug with more wiring terminals, a shell 19 with more first through holes 21 is required. At this time, the diameter of the shell 19 may be larger. Therefore, the present technical solution can cope with the installation of the adjustment unit 2 which requires more installation space.

[0212] In this embodiment, the mounting port 8 can also be a structure that protrudes both inward and outward. Meanwhile, the limiting structure 9 on the protrusion 13 can be detachable or telescopic, so that it can satisfy the installation of the adjustment unit 2 connected to the mounting port 8 from the outside, and also satisfy the installation of the adjustment unit 2 installed from the inner edge to the mounting port 8, so as to ensure the adjustability of the entire interface unit 3 is feasible, and further improve the application scenarios of this socket.

[0213] Example 9:

[0214] Please see Figure 14 The present invention provides the following technical solution: a compatible female socket, comprising:

[0215] Box 1, with a protrusion 13 in the direction of the opening of box 1, and an installation port 8 on the protrusion 13;

[0216] Adjustment unit 2 is rotatably connected to mounting port 8;

[0217] Interface unit 3, one end of interface unit 3 facing the opening of box 1 is used for connecting various external plugs, and the other end of interface unit 3 is connected to various wires;

[0218] A limiting bracket 15 is fixedly connected to the side of the protrusion 13 away from the adjustment unit 2. A limiting structure 9 is provided on the central hole wall of the limiting bracket 15, which is parallel to the moving direction of the interface unit 3. A sliding groove 10 is provided on the outer surface of the interface unit 3. The limiting structure 9 is slidably connected in the sliding groove 10. The interface unit 3 is threadedly engaged with the adjustment unit 2. The interface unit 3 is driven to move by rotating the adjustment unit 2.

[0219] The adjustment unit 2 has a snap-fit ​​part 12 on the end face opposite to the opening direction of the box 1. The snap-fit ​​part 12 fits with the edge of the mounting port 8, and the radial section of the snap-fit ​​part 12 is L-shaped.

[0220] The surface of the protrusion 13 has several screw holes 16, and the limiting bracket 15 is fixed by screwing screws 11 into the screw holes 16.

[0221] As an optional implementation of the present invention, this technical solution mainly focuses on the installation method of the limiting bracket 15. The advantage of fixing the limiting bracket 15 to the protrusion 13 by means of threads is that when the internal circuit of the socket generates a lot of heat or the heat of the external smart terminal diffuses into the box 1, it is not easy for the limiting bracket 15 to loosen or even fall off due to the glue melting due to heat.

[0222] In this embodiment, the protrusion 13 can be trumpet-shaped or tubular. The limiting bracket 15 can be installed on the inner wall of the protrusion 13 to screw in the screw 11, or it can be installed on the bottom plane of the box 1.

[0223] Example 10:

[0224] Please see Figure 15 The present invention provides the following technical solution: a compatible female socket, comprising:

[0225] Box 1, with a protrusion 13 in the direction of the opening of box 1, and an installation port 8 on the protrusion 13;

[0226] Adjustment unit 2 is rotatably connected to mounting port 8;

[0227] Interface unit 3, one end of interface unit 3 facing the opening of box 1 is used for connecting various external plugs, and the other end of interface unit 3 is connected to various wires;

[0228] A limiting bracket 15 is fixedly connected to the side of the protrusion 13 away from the adjustment unit 2. A limiting structure 9 is provided on the central hole wall of the limiting bracket 15, which is parallel to the moving direction of the interface unit 3. A sliding groove 10 is provided on the outer surface of the interface unit 3. The limiting structure 9 is slidably connected in the sliding groove 10. The interface unit 3 is threadedly engaged with the adjustment unit 2. The interface unit 3 is driven to move by rotating the adjustment unit 2.

[0229] The adjustment unit 2 has a snap-fit ​​part 12 on the end face opposite to the opening direction of the box 1. The snap-fit ​​part 12 fits with the edge of the mounting port 8, and the radial section of the snap-fit ​​part 12 is L-shaped.

[0230] The surface of the protrusion 13 facing the opposite direction of the opening of the box 1 is provided with several buckle grooves 17, and the surface of the limiting bracket 15 near the protrusion 13 is provided with buckles that cooperate with the buckle grooves 17.

[0231] As an optional implementation of the present invention, this technical solution mainly focuses on the installation of the limiting bracket 15. The limiting bracket 15 and the protrusion 13 can be detachably connected by inserting a buckle into the buckle. The advantage of this method is that the installation of the limiting bracket 15 can be completed quickly, which is faster than the threaded method and will not cause the glue to melt due to the large heat of the socket.

[0232] In this embodiment, the slots 17 are arranged in a circular array on the protrusions 13. This design makes the limiting bracket 15 have more stress points and makes it more difficult for radial slippage to occur after installation. It also prevents the buckle from disengaging from the slots 17 when the interface unit 3 rotates, thus preventing the limiting bracket 15 from falling off and ensuring the adjustability of the socket is not compromised.

The interface unit 3 is threadedly engaged with the adjustment unit 2. The interface unit 3 is driven to move by rotating the adjustment unit 2.

[0239] The adjustment unit 2 has a snap-fit ​​part 12 on the end face opposite to the opening direction of the box body 1. The snap-fit ​​part 12 fits with the edge of the mounting port 8, and the radial section of the snap-fit ​​part 12 is L-shaped.

[0240] As an optional embodiment of the present invention, the limiting bracket 15 is installed by setting the terminal block 14. The advantage of this fixing method is that it has the characteristics of better detachability and firmness of installing the limiting bracket 15 by screw 11, and also provides an installation position for the subsequent PCB board 18, so that the installation of the PCB board 18 with the limiting bracket 15 and the box 1 is more compact and firm, and the space occupied is not large.

[0255] Alignment lines 5 are provided on the inner wall of the box body 1 and the adjustment unit 2, and the outer surface of the adjustment unit 2 is provided with an anti-slip structure 6.

[0256] As an optional embodiment of the present invention, an alignment line 5 is provided on the bottom plane of the box 1 or the plane of the mounting port 8, and an alignment line 5 is also provided on the anti-slip structure 6. The distance that the interface unit 3 moves is measured according to the rotation of the adjustment unit 2. This design allows the user to clearly know how much angle to rotate so that the interface unit 3 moves to the appropriate position.

[0257] In this embodiment, the alignment line 5 can be 360 ​​lines evenly distributed in a ring;

[0258] Furthermore, four evenly distributed annular recesses 7 can be provided on the anti-slip structure 6. This provides a better grip for the user during adjustment, and the fact that the distance the interface unit 3 moves is fixed for each quarter rotation allows the user to precisely adjust the position of the interface unit 3.

[0259] Example 14:

[0260] Please see Figure 3 The present invention provides the following technical solution: a compatible female socket, comprising a housing 1, an adjustment unit 2 and an interface unit 3; the adjustment unit 2 is rotatably connected to the side of the housing 1 facing the opening of the housing 1;

[0261] Interface unit 3 includes a housing 19 and a decorative cover 20; the surface of housing 19 is provided with threads that mate with adjustment unit 2, housing 19 is slidably connected to adjustment unit 2, and interface unit 3 is driven to move by rotating adjustment unit 2;

[0262] The inner wall of the outer shell 19 is provided with a limiting groove 24 arranged along the moving direction of the interface unit 3. The decorative cover 20 is provided with an insert 25 that matches the limiting groove 24 on the side near the outer shell 19, so that the decorative cover 20 can be inserted into the end face of the outer shell 19 facing the opening of the box 1. The outer shell 19 is provided with a first through hole 21, and a conductive clip 23 for connecting various wires is fixedly connected in the first through hole 21. The decorative cover 20 is provided with a second through hole 22 for connecting various external plugs, and the second through hole 22 is aligned with the first through hole 21.

[0263] A safety door 26 is rotatably connected inside the decorative cover 20 and between the decorative cover 20 and the outer shell 19. The safety door 26 has several through holes 27 aligned with the first through hole 21, and also has clearance holes 28 for the insertion strip 25 to pass through. A baffle 29 is provided on one end of the decorative cover 20 near the safety door 26 and on the side of the second through hole 22. When the safety door 26 is installed on the decorative cover 20, the baffle 29 is located inside the through holes 27. A clearance groove 30 is provided on the side wall of the safety door 26 on the side of the through hole 27 to accommodate the baffle 29. The clearance groove 30 is inclined or arc-shaped.

[0264] The safety door 26 has an arc-shaped receiving groove 32 on the end face near the outer casing 19. A return spring 31 is provided in the receiving groove 32. The outer casing 19 has a protrusion 33 that can extend into the receiving groove 32 on the end face near the safety door 26. The two ends of the return spring 31 are fixedly connected to the end of the receiving groove 32 and the protrusion 33, respectively. The return spring 31 is kept in a stretched state at any time after installation, and the direction of the reaction force of the return spring 31 is the direction of rotation that drives the safety door 26 to block the first through hole 21.

[0265] As an optional embodiment of the present invention, the main modification in this technical solution is to the connection between the return spring 31 and the safety door 26 and the outer shell 19. By fixing the two ends of the return spring 31 to the safety door 26 and the outer shell 19 respectively, such as by hook 38, the return spring 31 can also be a tension spring. Although the installation is slightly more complicated than the compression method, this allows for a wider variety of spring cross-sectional shapes to be selected for the return spring 31. At the same time, the receiving groove 32 can also have more design options, such as a rectangular cross-section tension spring and receiving groove 32.

The external wire passes through the end cover 36 through the third through hole 37 and is placed in the conductive clip 23. The screw 11 is screwed into the mounting hole 40 and the positioning hole 41 so that the external wire and the conductive clip 23 are tightly fixed together to complete the electrical connection. The reset spring 31 is placed in the receiving groove 3. In step 2, the protrusion 33 on the outer shell 19 abuts against the other end of the reset spring 31, and then the insert strip 25 passes through the middle hole of the safety door 26 and is inserted into the limiting groove 24 to complete the assembly of the entire interface unit 3; the limiting bracket 15 is installed on the rear end of the protrusion 13, the box 1 is slid into the pre-embedded box 42, and the limiting structure 9 slides in the sliding groove 10. The interface unit 3 passes through the mounting port 8 and the front end of the decorative cover 20 protrudes from the mounting port 8; the adjustment unit 2 is installed on the interface unit 3, and the threaded engagement is completed. Then the adjustment unit 2 is pushed into the mounting port 8 to complete the snap-fit ​​between the adjustment unit 2 and the protrusion 13, thus completing the installation of the entire socket.

[0271] When in use, with the scale line 4 as a reference, since the interface unit 3 is slidably connected to the box 1 and threadedly engaged, the interface unit 3 can be moved by rotating the adjustment unit 2 to adjust the interface unit 3 to a position suitable for the plug of the smart terminal.
