Description

Technical Field

[0002] Junction boxes are widely used in electrical engineering to distribute and connect multiple wires in electrical wires for power transmission and signal transmission of different electrical equipment. Junction boxes are widely used in fields such as building construction, industrial installation and home wiring. They not only protect the connection points of wires from the influence of the external environment, but also realize the orderly arrangement and management of wires through the design of internal structure.

[0003] In the prior art, junction boxes usually arrange different types of wires (such as live wires, ground wires and neutral wires) side by side in the same row of junction boxes for connection and classification. Since the live wires, ground wires and neutral wires are usually arranged side by side in the same row of junction boxes, wires of different types are arranged densely, which can easily lead to confusion during wiring. Especially when it is necessary to increase or change the wiring in the future, wires of different types are staggered, which increases the complexity of operation and the risk of errors. Based on this, we propose a multifunctional junction box that can be marked and classified. Utility Model Content

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0028] This embodiment provides a multifunctional wire splitter box that can be marked and classified. As Figures 1 to 6 shown, it includes a box body 1. An opening is provided at the upper end of the box body 1 with a cover body 2. A wire inlet pipe 3 and a wire outlet pipe 4 are inserted and connected inside the box body 1. The ends of the wire inlet pipe 3 and the wire outlet pipe 4 both extend to the outside of the box body 1. In this embodiment, the wire inlet pipe 3 and the wire outlet pipe 4 are arranged oppositely, and there are two wire outlet pipes 4. The wire inlet pipe 3 is used for threading the main wire, and the wire outlet pipe 4 is used for threading the branch wires. A wire splitter is provided inside the box body 1. The wire splitter is slidably assembled on the first guide rail 6. The first guide rail 6 is fixed to the backing plate 5 by screws. The backing plate 5 is fixedly installed at the bottom of the inner cavity of the box body 1, making the wire splitter in an overhead state, which is beneficial for its heat dissipation. A wire splitting interface is provided on the end face of the wire splitter close to the wire outlet pipe 4, and a main wire interface is provided on the end face of the wire splitter close to the wire inlet pipe 3. The wire splitting interface and the main wire interface are electrically connected. When splitting the wire, the end of the main wire is fixed in the main wire interface, and the start end of the branch wire is fixed in the wire splitting interface, realizing the wire splitting operation. However, in actual applications, the splitting of a category of wires generally consists of a live wire, a ground wire, and a neutral wire. The live wires, ground wires, and neutral wires of different branch wires are usually arranged side by side in the same row of wire splitters. The wires of different categories are arranged densely. When wiring, although the wires usually have color markings, in actual operation, due to the dense arrangement of the wire splitters, the wires of different categories are prone to confusion, increasing the difficulty of identification. Especially during maintenance or repair, incorrect connection may lead to electrical failures or safety hazards. Therefore, we split the traditional side-by-side wire splitter into individual wire splitter columns 8. And in each individual wire splitter column 8, at least three first interfaces 9 are provided on the end face close to the wire outlet pipe 4, and at least three second interfaces 10 are provided on the end face close to the wire inlet pipe 3, so that the live wire, ground wire, and neutral wire of the same branch wire are arranged in a wire splitter column 8, and each wire splitter column 8 is only used to connect one branch wire, thereby avoiding the mixing of wires of different categories, reducing the complexity of wiring and maintenance, and achieving the purpose of classification.

[0029] On the basis of the above solution, if the splitters connected by several splitter columns 8 belong to the same category, these splitter columns 8 can be spliced together to form a large group. Specifically, the lower end of the splitter column 8 is slidably assembled on the first guide rail 6. Adhesive strips 82 are installed on both sides of the splitter column 8. Two adjacent splitter columns 8 are pasted together through the adhesive strips 82. In this embodiment, the adhesive strips 82 are made of Velcro, which can achieve simple and convenient adhesion. To improve the classification distinctiveness, a card slot 81 is installed at the upper end of the splitter column 8. Different colored cardboards or cardboard with information marked can be inserted into the card slot 81 to correspond the information of the corresponding splitter with the corresponding splitter column 8 one by one.

[0030] In this embodiment, the first interface 9 and the second interface 10 are electrically connected through an upper and lower conductive plate structure. Specifically, lower conductive plates 11 are fixedly installed at the bottom of the inner cavities of the first interface 9 and the second interface 10. An upper conductive plate 12 is slidably assembled in the vertical direction above the lower conductive plate 11. Two front and rear corresponding lower conductive plates 11 are connected through a connecting plate 13. The end of the wire with the insulating outer skin removed is inserted into the first interface 9 or the second interface 10. The lower conductive plate 11 moves downward in the vertical direction until the end of the wire is tightly pressed on the lower conductive plate 11, and the electrical connection between the bus and the splitter is realized by using the conductive characteristics of the metal.

[0031] During the implementation of the above solution, if each upper conductive plate 12 is driven individually in the vertical direction, it will cause the volume of the entire splitter column 8 to be too large and increase the operation difficulty. Therefore, we drive the upper conductive plates 12 in the same column with the same drive source. Specifically, connecting rods 14 are arranged on both sides of the upper conductive plates 12 in the same column. The upper conductive plates 12 are fixedly sleeved on the connecting rods 14. The connecting rods 14 are slidably assembled in the splitter column 8 in the vertical direction. A connecting plate 18 is jointly installed at the upper ends of the two connecting rods 14. A hand-twist screw 19 is rotatably connected to the upper end of the connecting plate 18. The hand-twist screw 19 is threadedly inserted through the splitter column 8 and extends above the splitter column 8 at the upper end. In the initial state, the distance between the upper conductive plate 12 and the lower conductive plate 11 is at the maximum value. At this time, the space between the lower conductive plate 11 and the upper conductive plate 12 is the largest, which is convenient for inserting the end of the wire. After the end of the wire is inserted, rotate the hand-twist screw 19 to drive the connecting plate 18 to move downward in the vertical direction. The connecting plate 18 drives the upper conductive plate 12 to move downward through the two connecting rods 14 until the upper conductive plate 12 and the lower conductive plate 11 are in close contact.

[0032] On the basis of the above scheme, since the first interface 9 or the second interface 10 is arranged vertically, and several wires in the same column need to complete the plug-in operation at the same time, due to the different heights of each interface, the insertion angle of the wire is also different. In order to facilitate the insertion of the end of the wire, we set the lower conductive plate 11 and the upper conductive plate 12 at an angle, so that an upwardly inclined interface is formed between the lower conductive plate 11 and the upper conductive plate 12; further, in order to adapt to the insertion angle of the wires at interfaces of different heights, we gradually reduce the inclination of the interfaces in the same column upward along the vertical direction, so as to facilitate the simultaneous insertion of multiple wire ends. In this embodiment, in order to increase the contact area between the wire and the conductive plate, we install a boss 111 on the upper end face of the lower conductive plate 11, and a groove corresponding to the boss 111 is opened on the lower end face of the upper conductive plate 12. The end of the wire is wound into a U-shaped structure and is sleeved on the boss 111, so as to increase the contact area between the wire and the lower conductive plate 11 and reduce the probability of the wire detaching from the interface.

[0033] During the process of fixing the wire end, the operator is required to keep the insertion action of the wire end stable. However, in actual applications, the operator's hand may shake slightly, which can easily cause the wire end to shift, or even cause the pressing area to be too small, causing subsequent poor contact and other problems. Therefore, it is necessary to adjust the position of the wire end in time. For this reason, we set the interface height of the same column to gradually decrease upward in the vertical direction, so that the wires in the same column are gradually fixed from the bottom to the top, reserving time for the operator to fine-tune the wire end later.

[0034] Since in the above scheme, the heights of the interfaces located in the same column are different, the lowering distances of the upper conductive plates 12 in the interfaces located at different positions are also different. In order to realize the synchronous lowering operation of the upper conductive plates 12 at different lowering heights, a fixed seat 15 is fixedly sleeved on the circumferential surface of the connecting rod 14, and a spring 16 is installed at the lower end of the fixed seat 15. A movable seat 17 is installed at the lower end of the spring 16. The movable seat 17 is slidably sleeved on the connecting rod 14, and the movable seat 17 and the upper conductive plate 12 are fixedly connected. When the connecting rod 14 moves downward in the vertical direction, the fixed seat 15 drives the movable seat 17 to move downward through the spring 16, and the movable seat 17 drives the upper conductive plate 12 to move downward. When the lowermost upper conductive plate 12 contacts the lower conductive plate 11, the upper conductive plate 12 stops moving and squeezes the spring 16. At this time, the connecting rod 14 continues to move downward until the upper conductive plates 12 in the same column all contact the corresponding lower conductive plates 11.

[0035] In addition, to facilitate the later arrangement of wires, a second guide rail 7 parallel to the first guide rail 6 is installed inside the box body 1. A second sliding seat 71 matching the number of splitter columns 8 is slidably assembled on the second guide rail 7. A first vertical rod 72 is installed at the rear part of the upper end of the second sliding seat 71, and a second vertical rod 73 matching the number of wire splice interfaces in one splitter column 8 is installed at the front part of the upper end of the second sliding seat 71. Cable clips 74 are slidably sleeved on both the first vertical rod 72 and the second vertical rod 73. The cable clips 74 are in interference fit with the first vertical rod 72 and the second vertical rod 73 to achieve static state. After the head of the splitter wire is connected to the splitter column 8, the cable is sequentially passed through the cable clips 74 on the first vertical rod 72 and the second vertical rod 73 to optimize the arrangement of the wires and reduce the workload of subsequent wiring.
