Description

Technical Field

[0001] This utility model belongs to the field of socket technology, specifically relating to a multi-functional socket structure. Background Technology

[0002] In modern electricity use, sockets are crucial devices connecting power sources and electrical equipment, and their functionality and safety directly impact power efficiency and security. Traditional four-wire three-phase sockets are typically used as standalone power supply devices to provide power to industrial equipment requiring three-phase power. Three-pole and two-pole sockets are widely used in homes and offices to power low-voltage single-phase equipment. However, in specific application scenarios, such as industrial production, commercial complexes, or mixed-use environments, users need to simultaneously use three-phase high-voltage equipment and single-phase low-voltage equipment. In such cases, standalone four-wire three-phase sockets or standalone three-pole / two-pole sockets are insufficient to meet the diverse needs of users.

[0003] Current technical solutions combine four-wire three-phase sockets with three-pole and two-pole sockets by connecting the power lines (including live, neutral, and ground wires) to the four-wire three-phase socket, three-pole socket, and two-pole socket respectively, allowing multiple devices to be powered simultaneously. However, this method results in complex and intertwined internal wiring, increasing wiring difficulty, occupying space, and raising maintenance costs. Three-pole and two-pole sockets receive power directly from the power lines without considering the balanced distribution of three-phase loads, which can easily lead to a bias in the three-phase power system, reducing power supply stability and even damaging equipment.

[0004] Therefore, there is an urgent need to improve the existing socket structure to address the shortcomings of the aforementioned technology. Utility Model Content

[0005] The purpose of this utility model is to provide a technical solution that can reduce the complexity of internal wiring in multi-functional socket structures (including four-wire three-phase sockets, three-pole sockets, and two-pole sockets) and improve the balanced distribution capability of three-phase loads, in order to address the shortcomings of existing technologies.

[0006] To achieve the above technical objectives, this application implements the following technical solution:

[0007] A multi-functional socket structure includes a base and a cover plate. The base is provided with a wiring module. The wiring module is connected to a power source and supplies power to the sockets in the base. The wiring module includes a live wire terminal, a neutral wire terminal and a ground wire terminal.

[0008] The socket includes a four-pole socket and at least one three-pole socket and / or at least one two-pole socket. The live wire terminal is connected to the live wire clip of the four-pole socket, and the ground wire terminal is connected to the ground wire clip of the four-pole socket.

[0009] The live wire clip is connected to at least one live wire terminal via a first connecting wire. The live wire terminal is used to provide phase power to the three-pole socket and / or two-pole socket. The ground wire clip is connected to the ground wire terminal via a second connecting wire. The ground wire terminal is used to ground the three-pole socket. The neutral wire terminal is connected to the neutral wire terminal of the three-pole socket and / or two-pole socket via a third connecting wire.

[0010] The above technical solution produces the following technical effects:

[0011] This application improves upon existing socket structures by directly connecting the live and ground wires from the power supply to the live and ground terminals of a four-wire three-phase socket. Simultaneously, connecting wires connect the live and ground terminals to a three-pole socket and a two-pole socket, respectively. This design reduces the need for independent wiring from the power supply to each socket, significantly reducing wiring complexity.

[0012] As a further improvement to the multifunctional socket structure of this utility model, both the three-pole socket and the two-pole socket are provided with phase clamps and protective doors. One end of the live wire terminal is connected to the live wire clamp through the first connecting wire, and the other end of the live wire terminal is fixedly connected to the phase clamp.

[0013] Preferably, the live wire clip extends to include a connector for connecting the first connecting wire to the live wire clip.

[0014] As a further improvement to the multi-functional socket structure of this utility model, when the live wire terminal is set to one, the number of phase clips is the number of three-pole plugs and / or two-pole plugs.

[0015] As a further improvement to the multi-functional socket structure of this utility model, a live wire terminal is connected to a phase wire clip, and the number of live wire terminals is the number of three-pole sockets and / or two-pole sockets.

[0016] As a further improvement to the multi-functional socket structure of this utility model, the base is provided with a frame that supports three-pole sockets and / or two-pole sockets. The frame is provided with at least one slot, and the slot is provided with at least two layers of slot plates. Each layer of slot plates is provided with a slot, and the slots of different layers of slot plates are staggered.

[0017] The second and / or third connecting wires are set via a card slot.

[0018] As a further improvement to the multifunctional socket structure of this utility model, the ground terminal is fixedly connected to the grounding clip of the three-pole socket, and the neutral terminal is fixedly connected to the neutral clip of the three-pole socket and / or the two-pole socket.

[0019] The number of grounding clips is the same as the number of three-pole sockets.

[0020] As a further improvement to the multi-functional socket structure of this utility model, the cover plate is provided with holes, including three-pole holes corresponding to three-pole sockets and / or two-pole holes corresponding to two-pole sockets and four-pole holes corresponding to four-pole sockets.

[0021] As a further improvement to the multifunctional socket structure of this utility model, the cover plate is provided with a front panel and side panels arranged around the perimeter of the front panel, and both the front panel and the side panels are provided with holes.

[0022] As a further improvement to the multi-functional socket structure of this utility model, the wiring module is set at the bottom of the base, and the power cord is fixed by screws for the live wire terminal, the neutral wire terminal and the ground wire terminal.

[0023] The cover plate has wiring positions, and wiring through holes are provided at the wiring positions. The wiring through holes correspond to the wiring modules, and a convex ring is provided inside the wiring through holes. The diameter of the convex ring is smaller than the diameter of the screw.

[0025] The protective cover has anti-slip texture. Attached Figure Description

[0076] The present invention will be further described in detail below with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0077] Implementation Method 1

[0078] like Figure 1-2 As shown, in order to reduce the load on the multi-functional socket structure combining a four-wire three-phase socket, a three-pole socket, and a two-pole socket in the prior art, this application connects the three live wires—L1, L2, and L3—and the neutral wire in the power cord to the four-pole socket 41 (the embodiment of the four-wire three-phase socket in this application, hereinafter referred to as the four-pole socket 41) via the wiring module 3. The four-pole socket 41 then provides phase power and grounding terminals to the three-pole socket 42 (the embodiment of the three-pole socket in this application, hereinafter referred to as the three-pole socket 42) and / or the two-pole socket 43 (the embodiment of the two-pole socket in this application, hereinafter referred to as the two-pole socket 43). This simplifies the socket structure and optimizes the wiring. This design effectively reduces the size of the socket while ensuring electrical safety and reliability. Furthermore, by reducing the need for independent wiring, it also lowers installation costs and maintenance difficulty.

[0079] Specifically, the multi-functional socket structure of this application includes a base 1 and a cover plate 2. A wiring module 3 is provided inside the base 1. The wiring module 3 is connected to a power source and supplies power to the socket 4 inside the base 1. The wiring module 3 includes a live wire terminal 31, a neutral wire terminal 32, and a ground wire terminal. In practical implementation, the live wire terminal 31, the neutral wire terminal 32, and the ground wire terminal are all part of the wiring module 3 structure, used for fixed connection to the power cord via screws 314.

[0080] Furthermore, the socket 4 includes a four-pole socket 41 and at least one three-pole socket 42 and / or at least one two-pole socket 43. The live wire terminal 31 is connected to the live wire clip 411 of the four-pole socket 41, and the ground wire terminal 33 is connected to the ground wire clip 412 of the four-pole socket 41. Specifically, the wiring module 3 is connected to the live wire clip 411 and the ground wire clip 412 via a conductive copper strip. The conductive copper strip ensures stable current transmission. In specific implementation, the four-pole socket 41 has a structure of three live wire clips 411 and one ground wire clip 412. Through the coordinated operation of the three live wire clips 411 and the one ground wire clip 412, a stable three-phase power supply of 380V and reliable grounding protection are provided, suitable for the operating environment of industrial and high-power equipment.

[0081] Furthermore, the live wire clip 411 is connected to at least one live wire terminal 5 via the first connecting wire 311. The live wire terminal 5 is used to provide phase power to the three-pole socket 42 and / or the two-pole socket 43. The ground wire clip 412 is connected to the ground wire terminal 6 via the second connecting wire 312. The ground wire terminal 6 is used to ground the three-pole socket 42. The neutral wire terminal 32 is connected to the neutral wire terminal 7 of the three-pole socket 42 and / or the two-pole socket 43 via the third connecting wire 313. The principle of the above technical solution, which simplifies the socket structure wiring by providing phase power to the three-pole socket 42 and the two-pole socket 43 through the four-pole socket 41, is as follows:

[0082] Firstly, in traditional socket designs, three-pole sockets 42 and two-pole sockets 43 require direct wiring from the live, neutral, and ground wires. This results in multiple sockets 4 being independently connected to the power supply, leading to complex wiring and low space utilization. The technical solution described in this application centrally connects the live and ground wires to the four-pole socket 41, distributing power to the three-pole sockets 42 and two-pole sockets 43 via the live wire clip 411 and the ground wire clip 412. Therefore, the live and ground wires only need to be connected once in the four-pole socket 41, and are then distributed to the other sockets 4 by internal wiring, avoiding the need for separate wiring from the power source and significantly reducing the number and complexity of internal wiring within the socket.

[0083] Secondly, in this application, the live wire clip 411 is connected to the live wire terminal 5 via the first connecting line 311, distributing phase power from the four-pole socket 41 to the three-pole socket 42 and the two-pole socket 43. The ground wire clip 412 is connected to the ground wire terminal 6 via the second connecting line 312, providing reliable grounding for the three-pole socket 42 and the two-pole socket 43. The neutral wire terminal 32 directly provides a neutral wire return to the three-pole socket 42 and the two-pole socket 43 via the third connecting line 313. Thus, the power supply function is decomposed into three modules: live wire terminal 5, ground wire terminal 6, and neutral wire terminal 7, and centrally connected at the four-pole socket 41, and then distributed through modularly distributed connecting lines, avoiding redundant wiring.

[0084] It should be noted that the number of three-pole sockets 42 and two-pole sockets 43 in this application is not fixed. Furthermore, this application is not limited to the case where three-pole sockets 42 and two-pole sockets 43 form a five-pole socket; a five-pole socket is a structure that simultaneously includes three-pole sockets 42 and two-pole sockets 43, and is not outside the scope of protection of this application. Specifically, both three-pole sockets 42 and two-pole sockets 43 in this application already include a phase clamp 421 and a neutral clamp 423; simultaneously, the three-pole socket 42 also includes a grounding clamp 422. These are essential components for realizing three-pole and two-pole sockets, and there are no unclear aspects in this embodiment. In addition, thanks to the four-pole socket 41, the multi-functional socket structure can be equipped with multiple three-pole sockets 42 or two-pole sockets 43, and is not limited to only three-pole sockets 42 or two-pole sockets 43.

[0085] Implementation Method 2

[0086] like Figure 1-4 As shown, unlike embodiment 1, to further reduce the complexity and improve safety of wiring between the four-wire three-phase socket, three-pole socket, and two-pole socket, specifically, both the three-pole socket 42 and the two-pole socket 43 are equipped with phase clamps 421 and protective doors 424. One end of the live wire terminal 5 is connected to the live wire clamp 411 via the first connecting wire 311, and the other end of the live wire terminal 5 is fixedly connected to the phase clamp 421. The phase clamp 421 is the component that supplies power to the electrical equipment via the three-pole socket 42 and the two-pole socket 43. When the plug of the electrical equipment is inserted into the socket, the phase clamp 421 contacts the live wire pin of the plug, providing live current to the electrical equipment. The phase clamp 421, in conjunction with the protective door 424, avoids the risk of electric shock due to accidental contact, and keeps the socket powered off when the plug is not inserted, improving overall safety.

[0087] Preferably, the live wire clip 411 extends to include a connector 4111, which connects the first connecting wire 311 to the live wire clip 411. Figure 4 As shown, the connector 4111 is fixed in this application by a screw connected to the first connecting line 311. It is worth noting that the arrangement of the connector 4111 in this application does not limit the way the first connecting line 311 is connected to the live wire clip 411. In this application, the way the first connecting line 311 is connected to the live wire clip 411 is not limited to through the connector 4111 and the screw; the position of the connector 4111, regardless of which side of the live wire clip 411, is within the protection scope of this application. Figure 4 The connection method shown is only the optimal embodiment and does not mean that it can only be achieved in this way. At the same time, the way the second connecting line 312 is connected to the ground terminal 6 is the same as the way the live wire clip 411 is connected to the first connecting line 311.

[0088] Furthermore, the live wire terminal 5 is connected to the live wire clip 411 of the four-pole socket 41 via the first connecting wire 311, forming the main power input path. The phase clips 421 are directly fixed in the three-pole socket 42 and the two-pole socket 43 via the live wire terminal 5, without the need for additional wiring. The live wire current is distributed to each phase clip 421 through the live wire clip 411, realizing the sharing of the power supply path and avoiding the complex design of independently pulling wires to each socket 4.

[0089] Furthermore, in specific implementation, when there is only one live wire terminal 5, the number of live wire clips 411 is the same as the number of three-pole sockets 42 and / or two-pole sockets 43. Specifically, only one live wire terminal 5 is set up as a unified live wire input point, directly supplying current to all three-pole sockets 42 and two-pole sockets 43 via the phase clips 421. This design avoids the need to draw a separate live wire for each socket 4. Secondly, regardless of the number of sockets 4 contained in the socket, such as multiple three-pole sockets 42 and / or two-pole sockets 43, only the corresponding number of phase clips 421 needs to be added; no adjustment to the live wire terminal 5 is required. However, if each phase clip 421 corresponds to one live wire terminal 5, the maximum number of live wire terminals 5 can only reach three, corresponding to the number of live wire clips 411 in a four-pole socket 41, and more first connecting wires 311 are needed to connect the live wire clips 411 to the live wire terminals 5. Furthermore, when the multi-socket 4 is running, the independent power supply of the phase clip 421 effectively reduces the risk of single-point overload, improves the stability of circuit operation, and avoids socket overheating or short circuit problems caused by live wire overload, thus ensuring electrical safety.

[0090] Furthermore, the ground terminal 6 is fixedly connected to the grounding clip 422 of the three-pole socket 42, and the neutral terminal 7 is fixedly connected to the neutral clip 423 of the three-pole socket 42 and / or the two-pole socket 43; the number of grounding clips 422 is the same as the number of three-pole sockets 42. The fixed connection between the ground terminal 6 and the grounding clip 422 of the three-pole socket 42 ensures the stability and safety of the grounding. The fixed connection between the neutral terminal 7 and the neutral clip 423 of the three-pole socket 42 and / or the two-pole socket 43 provides a complete current loop for the socket.

[0091] Specifically, the number of grounding clips 422 matches the number of three-pole sockets 42, ensuring reliable grounding protection for each three-pole socket 42. Furthermore, the number of neutral clips 423 matches the number of three-pole sockets 42 and two-pole sockets 43, ensuring the integrity of the current loop and balanced current distribution. This design not only simplifies wiring but also improves electrical safety and reliability, while reducing installation and maintenance costs.

[0092] Other aspects that are the same as in Implementation Method 1 will not be described again in this implementation method.

[0093] Implementation Method 3

[0094] like Figure 1-4As shown, unlike embodiment 2, this embodiment considers the phenomenon of unbalanced three-phase current due to uneven distribution of the insertion points 4 when multiple three-pole insertion points 42 and / or two-pole insertion points 43 are used, resulting in a bias. Specifically, the bias causes some phases of the three-phase voltage in the four-pole insertion point 41 to rise or fall, and the three-phase currents to be unequal, leading to reduced power utilization efficiency and potential power fluctuations and peak current instability in the power grid, affecting the stability and reliability of the power grid. Simultaneously, the bias causes one phase of the three phases to bear a greater load, leading to overload of electrical equipment and cables, increased operating temperature, and reduced equipment lifespan. Prolonged existence of this load imbalance may cause equipment overheating and damage, or even fire.

[0095] Based on this, this application connects one live wire terminal 5 to one phase clamp 421, and the number of live wire terminals 5 corresponds to the number of three-pole sockets 42 and / or two-pole sockets 43. That is, in this application, the number of live wire terminals 5 is at most three, corresponding to the number of live wire clamps 411 of the four-pole socket 41. Thus, each live wire terminal 5 draws current from one phase of the four-pole socket 41, providing power to multiple three-pole sockets 42 or two-pole sockets 43. The above design ensures that the load of each phase is as balanced as possible. This distribution method avoids the phase imbalance problem caused by overload of one phase, while making the three-phase current tend to be balanced.

[0096] Other aspects that are the same as in Implementation Method 2 will not be described again in this implementation method.

[0097] Implementation Method 4

[0098] like Figure 1-4 As shown, unlike Embodiment 1, to further improve the stability of the second connecting wire 312 and the third connecting wire 313, specifically, the base 1 is provided with a frame 11 supporting the three-pole socket 42 and / or the two-pole socket 43. The frame 11 is provided with at least one locking slot 111, and the locking slot 111 is provided with at least two layers of locking plates 112. Each layer of locking plate 112 is provided with a locking groove 1121, and the locking grooves 1121 of different layers of locking plates 112 are staggered. The second connecting wire 312 and / or the third connecting wire 313 are secured by the locking groove 1121. With this design, the second connecting wire 312 and the third connecting wire 313 are firmly fixed in the locking groove 1121, reducing the risk of poor contact or wire breakage caused by wire movement or vibration. The locking slot 111 design of the frame 11 not only improves the stability of the connecting wires, but also facilitates installation and maintenance, because the setting of the locking groove 1121 allows the connecting wires to be quickly inserted or removed without complicated operations. Furthermore, the multi-layered staggered design of the card plate 112 ensures that no interference occurs between the connecting wires even when high current is flowing, thus guaranteeing stable current transmission. This structural design significantly improves the reliability of the socket while reducing maintenance costs and failure rates.

[0099] Furthermore, the slot 1121 is not limited to the second connecting wire 312 and the third connecting wire 313; the first connecting wire 311 also benefits from this design, thereby ensuring that all connecting wires can be well secured and protected inside the socket. In specific implementation, the first connecting wire 311 can be fixed, but considering that the number of first connecting wires 311 may be too large, the slot 1121 used to fix the first connecting wire 311 needs to be determined according to the specific situation.

[0100] Furthermore, the multi-layered staggered design of the card plate 112 allows for layered arrangement of connection wires with different current ratings as needed, further optimizing current distribution and management. This design not only improves the electrical performance of the socket but also enhances its adaptability and durability in various usage environments.

[0101] Other aspects that are the same as in Implementation Method 1 will not be described again in this implementation method.

[0102] Implementation Method 5

[0103] like Figure 1-6 As shown, unlike Embodiment 1, to achieve the technical effect that the screws 314 of the live wire terminal 31, neutral wire terminal 32, and ground wire terminal 33 in the socket structure wiring module 3 of this application do not fall off even when the threads are loosened, the wiring module 3 is specifically located at the bottom of the base 1. The live wire terminal 31, neutral wire terminal 32, and ground wire terminal 33 are fixed with power cords by screws 314. The cover plate 2 has a wiring position 24, which has a wiring through hole 241 corresponding to the wiring module 3. A protruding ring 2411 is provided inside the wiring through hole 241, and the diameter of the protruding ring 2411 is smaller than the diameter of the screw 314. The principle of the above technical solution for achieving the live wire terminal 31, neutral wire terminal 32, and ground wire terminal 33 is that when the screw 314 is loosened, due to the presence of the protruding ring 2411, the screw 314 will be stuck under the protruding ring 2411, thereby preventing the screw 314 from completely disengaging from the wiring through hole 241. In this way, even under vibration or external force, screw 314 will not easily fall off, thus ensuring the stability and safety of the wiring. Furthermore, the wiring position 24 design of the cover plate 2 makes the wiring process more convenient, allowing users to easily perform wiring operations without worrying about the terminals coming loose. This design simplifies the maintenance and replacement of the power cord, while significantly reducing safety hazards caused by improper wiring.

[0104] Furthermore, the wiring position 24 is equipped with a protective cover 242, which snaps onto the wiring position 24, and the protective cover 242 is provided with anti-slip texture 2421. Both the protective cover 242 and the wiring position 24 have a locking structure that allows for easy installation and removal of the protective cover 242 and the wiring position 24. Simultaneously, the protective cover 242 is made of an anti-electric shock material and has anti-slip texture 2421 when opened, further enhancing user safety during operation.

[0105] Specifically, the anti-slip texture 2421 design of the protective cover 242 ensures that users can still firmly grip the protective cover 242 for operation in wet or oily environments, avoiding the risk of slipping. The anti-slip texture 2421 design when opening the cover makes it easier for users to operate the protective cover 242 for inspection or maintenance, while ensuring stability and safety during operation.

[0106] Furthermore, the cover plate 2 is provided with holes 21, including a three-pole hole 211 corresponding to the three-pole socket 42 and / or a two-pole hole 212 corresponding to the two-pole socket 43, and a four-pole hole 213 corresponding to the four-pole socket 41. Thus, users can select the appropriate three-pole or two-pole socket 43 according to the power and type of the appliance, or use the four-pole socket 41 to meet the grounding requirements of specific equipment.

[0107] Furthermore, the cover plate 2 is provided with a front panel 22 and side panels 23 arranged around the perimeter of the front panel 22.
