Description

Technical Field

[0001] This utility model relates to the field of building electrical wiring construction technology, and more specifically, to a quick-installation electrical wiring system. Background Technology

[0002] Prefabricated construction refers to a construction method in which the main components of a building are prefabricated in a factory and then transported to the construction site for assembly. It offers advantages such as fast construction speed, controllable quality, and environmental friendliness and energy conservation. In the electrical design and construction of buildings, the current method for wiring the electrical terminals entering the building is mostly to use protective conduits. The construction procedure is as follows: trenching, conduit installation, wire pulling, and connection. To facilitate wire pulling, a wire must be pre-installed inside the conduit during installation, and the ends of the protective conduit must be ground to prevent damage to the wires during pulling. For smooth wiring, conduit openings must be properly pre-treated, and junction boxes and connection boxes must be installed at bends and branches according to construction specifications. Special tools are required for bending conduits and connecting conduits during on-site construction, and wiring must be performed according to electrical engineering standards.

[0003] To improve construction efficiency, complete electrical connection conduits with pre-installed wiring can be selected for direct electrical construction. However, existing products typically use plastic shells, which have low strength and are easily damaged during construction, and their appearance is unsightly. If metal materials are chosen, the metal shell needs to be grounded to ensure safety. However, the grounding terminal design in existing designs is usually exposed, which is not only unsightly but also affects the stability of the connection. Grounding also requires additional wiring, which is more troublesome to assemble. In addition, the grounding terminal requires extra space, which increases the size of the connection conduit joint, making it difficult to conceal and construct. Utility Model Content

[0022] This embodiment discloses a quick-installation electrical conduit, such as... Figure 1-3As shown, the device may include: a connecting core assembly 10, a housing 20, a fixing member 30, and a connecting spring 40; the connecting core assembly 10 includes a core body 11 extending along the connecting direction, a power supply assembly 12, and a grounding assembly 13, the grounding assembly 13 and the power supply assembly 12 being respectively disposed within the core body 11 along the extending direction of the core body 11; the wire assembly 14 includes a power supply wire and a ground wire, the wire assembly 14 extending into the housing through the tail end; the power supply assembly 12 is used to connect to the power supply wire, the grounding assembly 13 is used to connect to the ground wire; the housing 20 is sleeved on the outside of the connecting core assembly 10; and the connecting spring 40 has at least The device includes a first sub-spring 41 and a second sub-spring 42 connected in sequence. The connecting spring 40 is made of elastic metal. The core body 11 is provided with a spring mounting groove 111. The connecting spring 40 is disposed in the spring mounting groove 111. The first sub-spring 41 is fixed in the spring mounting groove 111 by a fixing member 30. The second sub-spring 42 can extend out through the opening of the spring mounting groove 111 and bend in the same direction as the installation direction of the outer shell 20. The fixing member 30 is made of metal and is electrically connected to the grounding assembly 13. The second side of the connecting spring 40 is squeezed by the outer shell 20 and abuts against the inner side of the outer shell 20.

[0023] In the above technical solution, the metal fastener 30 and connecting spring 40 are used to enable the outer casing 20 to be electrically connected to the grounding assembly 13 in the core connection device. The wire assembly 14 includes a power supply wire and a ground wire. The power supply wire is used to provide power, while the ground wire is used for grounding connection, thereby enabling the outer casing 20 to achieve grounding through the ground wire, so that the outer casing 20 can meet the relevant grounding requirements and improve the safety of the outer casing 20. At the same time, the connecting spring 40 is configured to be composed of a first sub-spring 41 and a second sub-spring 42, which can be at an angle. The first sub-spring 41 is used for fixing, while the second sub-spring 42 can extend from the opening of the spring mounting groove 111, so as to connect with the metal outer casing 20. The connecting spring 40 is made of elastic material, and its first sub-spring 41 is used for fixing, while the second sub-spring 42 can extend from the opening of the spring mounting groove 111, so as to connect with the metal outer casing 20. The connecting spring 40 is made of elastic material, and its first sub-spring 41 is used for fixing, while the second sub-spring 42 can extend from the opening of the spring mounting groove 111, so as to connect with the metal outer casing 20. The first sub-spring 41 is fixed to the core connecting device by the fixing member 30. The second sub-spring 42 is compressed by the outer shell 20, which causes it to undergo elastic deformation, thereby achieving the purpose of electrically connecting the connecting spring 40 to the outer shell 20. In addition, taking advantage of the shape of the connecting spring 40, the second sub-spring 42 is bent towards the installation direction of the outer shell 20. During installation, it can be fixed to the connecting core device 10 first, and then the assembly consisting of the connecting core device 10, the fixing member 30 and the connecting spring 40 is installed into the outer shell 20. The second sub-spring 42 is bent in the opposite direction to the installation direction of the outer shell 20, which can be in the same direction as the movement direction of the outer shell 20, which facilitates the installation of the outer shell 20, does not cause resistance and can also prevent damage to the connecting spring 40 due to improper installation.

[0024] It should be noted that the mounting direction of the outer casing 20 refers to the direction of movement of the outer casing 20 relative to the internal connecting core device 10 during installation, such as... Figure 2 As shown, its installation direction is to the left; therefore, the second spring in the figure is bent to the left. The outer shell 20 can be made of metal to improve structural strength, and the connecting spring 40 can be made of spring steel, brass, or other metal materials, while also being able to withstand a certain degree of elastic deformation. The core body 11 can be composed of rubber, plastic, or a composite of multiple insulating materials. The core body 11, the power supply component 12, and the grounding component 13 can be integrally molded through injection molding, encapsulation, or other methods. Specifically, the power supply component 12 and the grounding component 13 can have structures such as metal pins or metal pin slots to adaptably complete the connection. When used as a plug, metal pins are typically used as the implementation method, while when used as a socket, they can be metal pin slots. Specifically, it can be as follows... Figure 1-3 As shown, one end is a connection end, and the other end is a cable line. The connection end can be connected to a matching interface to supply power. Multiple power supply components 12 can be included to connect the live wire and neutral wire respectively. Power supply components 12 and grounding components 13 can adopt the same structure, which may include metal pins or electrical connectors that match the metal pins. The fixing member 30 can be a screw, clip, or a metal structural member embedded in the core body 11. It can be directly connected to the grounding component 13, or indirectly connected to the grounding component 13 through internal connecting wires, etc. It can be directly connected to the structural member used for connecting the ground wire, or it can be directly connected to the ground wire.

[0025] As a specific implementation method, such as Figure 2 As shown, the fastener 30 is configured to extend into the core body 11 radially and connect to the grounding assembly 13. The spring mounting groove 111 reduces the gap between the core body 11 and the outer casing 20, preventing it from wobbling. It also reduces the need for additional structures to fix the core body 11. The spring mounting groove 111 can be a recess or a through hole. When it is a recess, the fastener 30 needs to be able to pass through the core body 11. If it is a through hole, the grounding assembly 13 can be partially exposed at the bottom of the spring mounting groove 111. In this case, the fastener 30 can be directly connected to it without passing through the core body 11. This configuration also reduces the radial dimension of the core body 11.

[0026] When the quick-install electrical conduit in this application is like Figure 2-3As shown, the quick-install electrical conduit also includes a wire protection tube 50, which is made of metal and is fitted over the outside of the wire assembly 14. The wire protection tube 50 is electrically connected to the outer casing 20. The wire assembly 14 may include a live and neutral wire for power supply and a ground wire for grounding, allowing the outer casing 20 to be grounded through connection with the ground wire. Simultaneously, to protect the wire protection tube 50, the outer side of the wire assembly 14 may be covered with the wire protection tube 50, which can be made of materials such as plastic or metal. When the wire protection tube 50 is made of metal, better structural strength can be obtained. However, similar to the outer casing 20, the wire protection tube 50 also needs to be grounded to ensure safety. In the above technical solution, grounding is achieved by electrically connecting the wire protection tube 50 to the outer casing 20. The electrical connection method can be direct or indirect. When indirect, a conductive structure such as a wire can be used to achieve the electrical connection. Specifically, the wire protection conduit 50 can be a bendable spiral metal conduit or a fixed conduit, i.e., a regular conduit structure that cannot be bent. In addition, coatings or plastic coatings can be applied to the inner or outer layers of the wire protection conduit 50 as needed to achieve further technical effects. For example, to prevent corrosion of the wire protection conduit 50 caused by external factors, a plastic coating layer can be applied to the outer side of the wire protection conduit 50. The plastic coating layer can play a role in preventing corrosion. Alternatively, a powder coating can be applied to the inner surface of the wire protection conduit 50, such as using epoxy resin powder material, to form a dense protective film on the inner wall of the metal pipe, effectively isolating the inner wall of the pipe from contact with corrosive media (such as acids, alkalis, salts, etc.) in the transported medium, and preventing corrosion of the inner wall of the pipe.

[0027] However, for the connection between the metal protective tube 50 and the outer casing 20, an indirect connection would add extra components, while a direct connection via contact alone, lacking fixation or support, would result in an unstable connection. Furthermore, the wire protective tube 50 lacks a structure to prevent it from detaching from the outer casing 50. Figure 2As shown, the rear end of the outer casing 20 is provided with an inner support portion 21, which can support the inner side of the wire protection tube 50. Using the inner support portion 21, it can be inserted into the inner side of the wire protection tube 50, causing a slight elastic deformation of both the inner support portion 21 and the wire protection tube 50, thereby achieving the purpose of fixing the wire protection tube 50 and making an electrical connection. Furthermore, the diameter of the inner support portion 21 can be set as a tapered shape that gradually decreases in the direction away from the outer casing 20, with its maximum diameter greater than the inner diameter of the wire protection tube 50. This facilitates the installation of the wire protection tube 50 while also tightening it inside the tube, achieving a better anti-loosening effect. Simultaneously, since the inner support portion 21 can also be made of metal, when it tightens and connects to the wire protection tube 50, it enables the wire protection tube 50 to achieve an electrical connection with the outer casing 20 through the inner support portion 21, thereby achieving the purpose of grounding.

[0028] Furthermore, such as Figure 2 As shown, the quick-install electrical conduit also includes a tail connector 60 and a pressure plate 70. The pressure plate 70 is annular and can be fitted onto the outer side of the wire protection tube 50 corresponding to the inner support portion 21. The outer casing 20 also includes a guide portion 22 arranged around the inner support portion 21. A first gap space is provided between the guide portion 22 and the inner support portion 21. The ends of the pressure plate 70 and the wire protection tube 50 can extend into the first gap space. The tail connector 60 is annular. A pushing portion 61 is provided at the end of the tail connector 60 away from the outer casing 20. The pushing portion 61 extends inward in the radial direction and can push the pressure plate 70 into the first gap space.

[0029] The guide portion 22 guides the pressure plate 70 into the first interval space. In the radial direction, the inner diameter of the pressure plate 70 can be set slightly smaller than the outer diameter of the wire protection tube 50, so that the pressure plate 70 can squeeze the wire protection tube 50 inward. The inner support portion 21 supports the wire protection tube 50 internally, so that the wire protection tube 50 can be clamped in the first interval space in the radial direction. The pressure plate 70 can be clamped between the guide portion 22 and the wire protection tube 50. In the axial direction, the tail connector 60 can push the pressure plate 70 towards the head and prevent it from coming out of the first interval space. Specifically, the tail connector 60 can be set as a tapered shape with a gradually decreasing diameter.

[0030] Furthermore, such as Figure 2As shown, the inner support portion 21 and the guide portion 22 are connected by a connecting portion 23. The side of the connecting portion 23 facing the first space is a tapered surface with a diameter that gradually increases in the direction toward the wire protection tube 50. The tapered surface of the connecting portion 23 can guide the pressure plate 70 to deform further inward under the push of the tail connector 60. When the end of the pressure plate 70 contacts the connecting portion 23, it is subjected to the action of the inclined tapered surface, thereby pressing the wire protection tube 50 inside it.

[0031] In addition, as an optional implementation method, such as Figure 2 As shown, the inner side of the pressure plate 70 is provided with an abutment portion 71, which can abut against the end of the wire protection tube 50; the inner side of the wire protection tube 50 is provided with a first internal thread, and the outer peripheral surface of the inner support portion 21 is provided with a first external thread that matches the first internal thread. By using threaded installation, the axial movement of the wire protection tube 50 can be further limited, and the connection strength between the wire protection tube 50 and the inner support portion 21 can be strengthened.

[0032] If the inner part 50 of the wire protection tube has a powder coating, the wire protection tube 50 cannot achieve electrical connection with the outer shell through the inner support part 21. In this case, the outer shell 20 can contact the pressure plate 70. The pressure plate 70 is made of metal. At this time, the pressure plate 70 contacts the outer side of the wire protection tube 50, so that the wire protection tube 50 can achieve electrical connection with the outer shell 20, so as to achieve the purpose of grounding the wire protection tube 50.

[0033] In order to protect the internal components from water ingress, such as Figure 2 As shown, the head of the outer casing 20 is provided with a second external thread. The quick-connect electrical conduit also includes an end nut 80 and a first sealing ring 90. The head of the core body 11 is provided with a fixed boss that protrudes in the radial direction. The fixed boss is annular. The head of the end nut 80 is annular and is provided with a fixed flange that extends inward in the radial direction. The inner annular surface of the first sealing ring 90 is attached to the core body 11. The tail end of the end nut 80 is provided with a second internal thread that matches the second external thread. The end nut 80 can be installed on the outer casing 20. The fixed flange can press the first sealing ring 90 against the head end face of the outer casing 20.

[0034] The end nut 80 restricts the axial movement of the core body 11 inside the housing 20 at the head. It also presses the sealing ring against the end of the housing 20. The end of the housing 20 is the connection between the housing 20 and the internal core body 11. There is a gap where moisture can enter. The sealing ring is made of elastic material such as rubber. Its inner ring surface fits against the core body 11 to prevent moisture from entering. At the same time, the compression of the sealing ring in the axial direction can also seal the gap at the connection between the housing 20 and the core body 11. Therefore, setting the sealing ring here can prevent moisture from entering in this direction.

[0035] When quick-connect electrical conduits are connected to other structures, to prevent them from shaking or coming loose, such as... Figure 2 As shown, the quick-install electrical conduit also includes a connecting nut 100, which is sleeved on the outside of the end nut 80 and can move in the axial direction. The tail end of the connecting nut 100 is provided with a limiting flange 101 extending inward in the radial direction, which can abut against the tail end of the connecting nut 100.

[0036] The connecting nut 100 is provided to further secure it to the connected structure after the quick-installation electrical conduit is installed. The rear limiting flange 101 prevents it from coming off from the head position of the housing 20, thereby preventing the connecting nut 100 from falling off when not installed.

[0037] To further seal, as one implementation method, such as Figure 2 As shown, the quick-install electrical conduit also includes a second sealing ring 110. A sealing ring portion is provided at the tail end of the core body 11, and the sealing ring portion has at least one sealing ring fixing groove 15. The sealing ring portion is fitted to the inner circumferential surface of the outer casing 20, and the second sealing ring 110 is disposed within the sealing ring fixing groove 15. The second sealing ring 110 can seal the gap between the core body 11 and the outer casing 20 from the tail end. Since the connecting wire and other structures can be connected to the core body 11 as a whole through methods such as adhesive coating, there is only a gap between the core body 11 and the outer casing 20 in the tail direction. Therefore, the second sealing ring 110 can effectively seal from the tail direction. Furthermore, multiple second sealing rings 110 can be provided at intervals; as shown in the figure, two are provided.

[0038] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
