Description

Technical Field

[0001] The utility model belongs to the technical field of cable distribution boxes, and particularly relates to a cable distribution box. Background Art

[0002] A low-voltage cable distribution box is a device used for tapping, branching, connecting, and converting circuits of cable lines, and most of them are used outdoors. This device is widely used in the power supply of small users such as street lights in urban power grids. By dividing the main cable into several small-area cables to access the load, it effectively avoids the waste of cable use. And on long-distance lines, when the cable length cannot meet the requirements, a cable distribution box is used for transfer, ensuring the safety and reliability of power supply.

[0003] Generally, the number of branches of a low-voltage cable distribution box is the sum of the number of incoming lines and the number of outgoing lines. Generally, the number of branches of a low-voltage distribution box is 3-7. The cable enters from the incoming line port on one side of the bottom, and after corresponding branch connections, it exits from the outgoing line port. When the bottom is opened at both the incoming line port and the outgoing line port, there will be more incoming and outgoing lines side by side, and the cables are easy to tangle with each other inside the device, which is not convenient for distinction. And for the existing wire bundling board or support member that clamps the wire harness, the clamping position is prone to breakage when the wire harness is bent. Content of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a cable distribution box.

[0005] The technical solution adopted by the utility model is as follows: A cable distribution box includes a protective housing and a wire bundling device located inside the protective housing; the protective housing has a corresponding accommodation chamber, and an incoming line port and an outgoing line port are opened at the bottom of the accommodation chamber; the wire bundling device includes a sliding support member that can slide between both sides inside the protective housing; a multi-stage telescopic rod connected to the sliding support member and performing telescopic operation along the front-back direction inside the protective housing; a wire bundling member connected to the telescopic end of the multi-stage telescopic rod, with a wire passing channel defined inside, and the wire passing channel has a corresponding limiting operation length and a limiting operation inner diameter.

[0006] Further, the wire bundling member is damping rotatably connected to the telescopic end of the multi-stage telescopic rod, and the inclination angle of the wire passing channel can be rotatably adjusted.

[0007] Further, the wire passing channel is arranged with the middle part inwardly converging and both ends outwardly expanding.

[0008] Further, a limiting rod and a support cross bar are fixedly installed side by side between the inner side walls on both sides of the protective housing, and the sliding support member is slidably connected to the limiting rod and the support cross bar.

[0009] Further, protective doors are provided on both sides of the front side of the protective housing.

[0010] Further, fixed vertical plates are provided on the inner walls of both sides of the protective housing, and a fixed horizontal plate is installed between the fixed vertical plates. The fixed horizontal plate is located above the wire bundling device.

[0011] Further, heat dissipation holes are formed in two opposite side walls of the protective housing. The upper cover at the top of the protective housing is hollow to form a ventilation cavity. The ventilation cavity is connected to the inside of the protective housing through a ventilation opening. Both ends of the ventilation cavity extend out of both sides of the protective housing, and a ventilation port communicating with the outside is provided at the bottom of the extended end of the ventilation cavity.

[0012] After adopting the above structure, the beneficial effects of the present utility model are as follows: A cable distribution box proposed by the present utility model can separate the incoming line cables and the outgoing line cables through the provided wire bundling device, avoiding wire harness entanglement. Moreover, the wire passing channels and the limiting channels formed by the wire bundling members have corresponding lengths and limiting working inner diameters, and the angle can be rotated and adjusted, which can facilitate the adaptive guiding of the wire harness to enter and exit. When the wire harness is not clamped, the wire harness is limited and separated, and the wire harness has a certain activity space in the limiting channel. When the part extending out of the wire passing channel is bent, the limiting part is not easily broken or damaged. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described 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 embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0021] As Figures 1-4 shown, a cable distribution box includes a protective housing 1 and a wire bundling device 2 located inside the protective housing 1 for separating cables. The protective housing 1 has a corresponding accommodation chamber, and an inlet 3 and an outlet 4 are provided at the bottom of the accommodation chamber. Among them, protective doors 10 are provided on both sides of the front side of the protective housing 1, and the protective doors 10 can be opened from the front side and the rear side for maintenance. In addition, fixed vertical plates 11 are provided on the inner walls of both sides of the protective housing 1, and a fixed horizontal plate 12 is installed between the fixed vertical plates 11. The fixed horizontal plate 12 is located above the wire bundling device 2. The fixed vertical plates 11 and the fixed horizontal plate 12 can be made of channel steel, and installation holes are sequentially opened on both sides of the channel steel to facilitate installation and fixing operations.

[0022] In some preferred embodiments, heat dissipation holes 13 are provided on two opposite side walls of the protective housing 1. The heat dissipation holes 13 can have a downward opening on the outside of the protective housing 1 to play a role in dust prevention. The upper cover of the top end of the protective housing 1 is hollow to form a ventilation cavity 14. The ventilation cavity 14 is connected to the inside of the protective housing 1 through a ventilation port 15. Both ends of the ventilation cavity 14 extend out of both sides of the protective housing 1, and a ventilation port 16 communicating with the outside is provided at the bottom of the extended end of the ventilation cavity 14 to facilitate ventilation and heat dissipation between the inside and the outside of the protective housing 1. A heat dissipation device such as a heat dissipation fan can be installed at a suitable position in the heat dissipation cavity to assist in heat dissipation inside the device.

[0023] In some preferred embodiments, the wire bundling device 2 includes a sliding support member 5 that can slide between two sides inside the protective housing 1. Specifically, a limiting rod 8 and a support cross bar 9 are fixedly installed side by side between the inner side walls of the two sides of the protective housing 1. The sliding support member 5 is slidably connected to the limiting rod 8 and the support cross bar 9, and the sliding support member 5 is in damping sliding connection with the limiting rod 8 and can stay at a suitable working position;

[0024] The wire bundling device 2 further includes a multi-stage telescopic rod 6 and a wire bundling member 7 connected to the telescopic end of the multi-stage telescopic rod 6. The multi-stage telescopic rod 6 is connected to the sliding support member 5 and performs telescopic operation along the front-rear direction inside the protective housing 1; the wire bundling member 7 is connected to the telescopic end of the multi-stage telescopic rod 6. A wire passing channel is defined inside the wire bundling member 7. The telescopic end of the multi-stage telescopic rod 6 is in damping rotational connection with the wire bundling member 7, and the inclination angle of the wire passing channel can be adjusted.

[0025] It should be noted that the wire passing channel has a corresponding limiting working length and a limiting working inner diameter, and the wire passing channel is arranged with an inwardly converging middle part and outwardly expanding ends. The wire passing channel adaptively guides the incoming and outgoing directions of the wire harness by adjusting the angle, and the wire passing channel does not clamp and restrain the wire harness, but restricts the wire harness in a relatively movable space, enabling the wire harness to move to a certain extent. Therefore, when the part outside the wire passing channel can be appropriately bent, the wire harness is not easily broken or damaged (without a clamping end, the limiting position is not easily broken or damaged).

[0026] The specific use is as follows: When installing the cable, sealing and other treatments are carried out at the inlet 3 and the outlet 4 for the incoming and outgoing wires; the incoming cable and the branch wires of the outgoing cable respectively extend into the wire passing channels of the corresponding wire bundling members 7. The horizontal position of the wire harness can be adjusted through the multi-stage telescopic rod 6, enabling the wire harnesses to be misaligned, and the wire bundling member 7 can be rotated to adaptively guide the advancing direction of the wire harness. The wire harnesses are separated from other wire harnesses through the wire passing channels, and there is no fixed clamping position when the wire harnesses enter and exit the wire passing channels. When the wire harnesses are appropriately bent, the limiting positions are not easily broken or damaged.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural methods and embodiments without creative efforts without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention. Each component of this application can be driven by a corresponding external motor, which is prior art and will not be elaborated in this application.
