Description

Technical Field

[0001] This utility model specifically relates to a wiring device for adding wiring to a multi-control junction box, belonging to the field of building electrical engineering. Background Technology

[0002] In home renovation, junction boxes are an indispensable electrical accessory. During installation, electrical wires are typically run through conduits, a method that is both safe and neat. However, wires inevitably have joints during transmission, especially when connecting to wall switches or wall sockets. This necessitates a specialized device for connecting and transitioning wires, hence the junction box. The main function of a junction box is to provide a safe and reliable connection space for electrical wires. The conduit connects to the junction box via a suitable interface, guiding the wires from the conduit into the junction box. Inside the junction box, the wires are organized, connected, and precisely aligned with the terminals of the wall switch or wall socket. This not only ensures the stability of the wire connection but also effectively prevents safety hazards such as loosening or short circuits during the connection process.

[0003] In modern home decoration, people usually pursue a simple and practical design concept, and multi-control switches are widely used in home decoration. Multi-control switches allow the same light fixture to be controlled from multiple locations; however, their installation places higher demands on electricians. Because the wiring design of multi-control switches is more complex, requiring the connection of multiple wires to achieve its function, the number of wires in the junction box where the multi-control switch is installed increases significantly. When wiring, electricians often need to connect multiple wires together to ensure correct current transmission and achieve the multi-control function. This complex wiring method makes the space inside the junction box very limited.

[0004] In such situations, the limited space within the junction box often makes it difficult to accommodate excessive wiring and the multi-control switch itself. The accumulation of wires can completely fill the junction box, even preventing the multi-control switch from being installed properly. This not only creates difficulties for electricians but can also affect the safety and stability of the entire electrical system. Overcrowded wiring connections can lead to poor contact, short circuits, and even fire hazards. Therefore, when installing multi-control switches, it is crucial to plan the junction box space appropriately and choose suitable wiring methods. Utility Model Content

[0007] The wiring mechanism includes two side rods, two sliding grooves, multiple locking rods, and several multi-wire terminals. Each side rod is provided with a sliding groove, which is slidably disposed in the junction box. Multiple locking rods are arranged equidistantly between the two side rods along the length of the side rods. One end of each locking rod is disposed on one of the two side rods, and the other end of each locking rod is disposed on the other of the two side rods. Several multi-wire terminals are provided on the locking rods.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention, through the ingenious combination of multi-wire terminals and clamps, enables the scientific and rational arrangement of wires within the junction box. It effectively solves the problem of overcrowded wire connections in traditional junction boxes, thus avoiding safety hazards such as poor contact and short circuits caused by wire accumulation.

Detailed Implementation

[0028] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0029] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 This embodiment describes a wiring device for a multi-control junction box, comprising a junction box 1 and a wiring mechanism 2. The wiring mechanism 2 is slidably disposed within the junction box 1. The wiring mechanism 2 includes two side rods 2-1, two sliding grooves 2-2, multiple locking rods 2-3, and several multi-wire terminals 2-4. Each side rod 2-1 is provided with a sliding groove 2-2, which is slidably disposed within the junction box 1. The multiple locking rods 2-3 are arranged equidistantly between the two side rods 2-1 along the length direction of the side rods 2-1. One end of each locking rod 2-3 is disposed on one of the two side rods 2-1, and the other end of each locking rod 2-3 is disposed on the other of the two side rods 2-1. Several multi-wire terminals 2-4 are disposed on the locking rods 2-3.

[0030] According to the requirements, install several multi-wire terminals 2-4 on the corresponding positions of the clamps 2-3, and then install the auxiliary wires 3 and the main wires 4 on the corresponding positions of the multi-wire terminals 2-4 according to the requirements. Then, install the wiring mechanism 2 into the junction box 1 through the sliding groove 2-2.

[0031] Specific Implementation Method 2: This implementation method is a further limitation of Specific Implementation Method 1. The inner walls on both sides of the wire box 1 are respectively provided with U-shaped protrusions 1-1, and the sliding groove 2-2 is slidably disposed on the U-shaped protrusions 1-1. The wire box 1 is circumferentially machined with multiple wire tube holes 1-2.

[0032] The conduit hole 1-2 is used to connect to the conduit, and the U-shaped protrusion 1-1 is the connection position for the multi-control switch.

[0033] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. Each multi-wire terminal 2-4 includes a main body 2-4-1, a metal part 2-4-5, four arc-shaped buckles 2-4-2, five threaded tubes 2-4-3, and five threaded caps 2-4-4. An arc-shaped buckle 2-4-2 is provided at each of the four corners of the main body 2-4-1. The arc-shaped buckles 2-4-2 are provided on the clamping rod 2-3. A strip-shaped cavity 2-4-11 is machined on the back of the main body 2-4-1. A metal part 2-4-5 is provided in the strip-shaped cavity 2-4-11. Five round holes 2-4-12 are machined on the front of the main body 2-4-1 along its length. A threaded tube 2-4-3 is provided at each round hole 2-4-12 of the main body 2-4-1. Each threaded tube 2-4-3 is threadedly connected to a threaded cap 2-4-4.

[0034] When performing wiring operations within junction box 1, the five threaded caps 2-4-4 must first be removed from the wiring mechanism 2 to facilitate subsequent wire installation. Next, the auxiliary wire 3 and main wire 4 are pre-treated by removing the insulation layer at appropriate locations to expose the internal conductors, ensuring good contact between the wires and the metal component 2-4-5 within the wiring mechanism 2. Then, the treated auxiliary wire 3 and main wire 4 are inserted into the wiring mechanism 2 through the strip cavity 2-4-11. At this point, the auxiliary wire 3 and main wire 4 are in close contact with the metal component 2-4-5 to ensure circuit continuity. Simultaneously, the auxiliary wire 3 and main wire 4 emerge sequentially from the port of the threaded tube 2-4-3, preparing for subsequent fixing and connection.

[0035] After the initial wiring installation is completed, the sliding groove 2-2 is slidably mounted on the U-shaped protrusion 1-1, and the wiring mechanism 2 is smoothly pushed into the junction box 1 through the sliding function of the sliding groove 2-2. During the pushing of the wiring mechanism 2, the auxiliary wire 3 and the main wire 4 are pulled outwards at the same time, shortening the length of the wires remaining in the junction box 1. This effectively reduces the space occupied by the auxiliary wire 3 and the main wire 4 in the junction box 1, further optimizing the spatial layout within the junction box 1 and providing sufficient space for the subsequent installation of multi-control switches.

[0036] After the wiring mechanism 2 is pushed into the junction box 1 and reaches the appropriate position, the auxiliary wire 3 is cut along the port of the threaded tube 2-4-3 to ensure that the wire length matches the installation requirements. Then, the previously removed threaded cap 2-4-4 is reinstalled on the threaded tube 2-4-3 to seal the location of the auxiliary wire 3 and ensure its safety during subsequent use. Finally, the end of the main wire 4 is connected to the corresponding position of the multi-control switch, completing the entire wiring and connection operation.

[0037] The above steps not only ensure the proper installation and fixation of the wires, but also effectively prevent the problem of overcrowding in the junction box caused by excessively long wires, further improving the standardization and safety of wiring inside the junction box.

[0038] Specific Implementation Method Four: This implementation method is a further limitation of Specific Implementation Method One, Two or Three. The metal part 2-4-5 is U-shaped. One end of the metal part 2-4-5 is provided with an arc-shaped metal piece 2-4-52 along its length direction. The other end of the metal part 2-4-5 is provided with another arc-shaped metal piece 2-4-52 along its length direction. The metal part 2-4-5 is machined with five wire holes 2-4-51 along its length direction. The positions of the wire holes 2-4-51 and the round holes 2-4-12 correspond one-to-one.

[0039] The stripped secondary wire 3 or main wire 4 passes between the two arc-shaped metal plates 2-4-52 and contacts the arc-shaped metal plates 2-4-52, thereby connecting multiple secondary wires 3 and main wires 4 together. The secondary wire 3 or main wire 4 passes through the corresponding wire hole 2-4-51 and round hole 2-4-12 and exits from the threaded tube 2-4-3.

[0040] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Method 1, 2, 3 or 4. A protrusion 2-4-31 is provided on the inner wall of the port of each threaded tube 2-4-3. When the auxiliary wire 3 or the main wire 4 passes through the threaded tube 2-4-3, the protrusion 2-4-31 abuts against the outer wall of the auxiliary wire 3 or the main wire 4, and plays a role in clamping and fixing.

[0041] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Method One, Two, Three, Four or Five. Each arc-shaped buckle 2-4-2 has a rubber pad 2-4-21 on its inner wall. The rubber pad 2-4-21 increases the friction between the arc-shaped buckle 2-4-2 and the lever 2-3, effectively preventing the arc-shaped buckle 2-4-2 from falling off the lever 2-3.

[0042] Working principle:

[0043] During wiring, the auxiliary wire 3 and main wire 4 first need to be pre-processed. The insulation layer is removed at appropriate locations on the auxiliary wire 3 and main wire 4 to expose the internal conductive parts, preparing for subsequent connections. Then, based on the installation location of the multi-control switch and the spatial layout within the junction box 1, the auxiliary wire 3 and main wire 4 are precisely cut to lengths matching the installation requirements. After cutting the wires, the auxiliary wire 3 and main wire 4 are respectively installed on multi-wire terminals 2-4, ensuring a secure and reliable connection between the wires and terminals, thereby guaranteeing normal circuit continuity.

[0044] Then, several multi-wire terminals 2-4 are sequentially installed on the corresponding clamps 2-3. The design of the clamps 2-3 provides stable support for the multi-wire terminals 2-4 and ensures that they remain neatly arranged during installation, avoiding tangling or interference between wires. By rationally arranging the positions of the multi-wire terminals 2-4, the space utilization efficiency within the junction box can be further optimized, providing favorable location conditions for the subsequent installation of multi-control switches.

[0045] Finally, the entire wiring mechanism 2 is smoothly slidably installed into the junction box 1 using the sliding groove 2-2. The design of the sliding groove 2-2 not only makes the installation process of the wiring mechanism 2 more convenient and efficient, but also ensures that each wire bundle is separated after installation, in its own independent state, and has self-positioning stability. In this way, the wiring mechanism 2 can separate the wires and the multi-control switch into different spaces in the junction box 1, thereby ensuring that the space inside the junction box 1 can accommodate too many wires and the multi-control switch itself when installing the multi-control switch, while making the wire arrangement more standardized and orderly.
