Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and in particular to a junction box for network engineering. Background Technology

[0002] As a terminal device for distribution cables or optical fibers, the junction box is responsible for connecting the distribution cables or optical fibers to the user's line section and for branching the main line. It plays a vital role in the communication network.

[0003] In practical applications, due to size and cost considerations, the cables inside the junction box typically generate a significant amount of heat during operation. If the internal cables become tangled, it could potentially pose a safety risk. This is why the design of junction boxes needs to consider the spacing between cables to prevent heat buildup.

[0004] Currently, the technical solution to the problem of overheating of cables inside junction boxes is usually to install a fan on the side of the box to promote airflow and reduce the temperature.

[0005] However, in practical applications, we have observed that while the fan can reduce the internal temperature of the junction box, its presence also introduces noise issues and limits the installation location of the junction box. Under improper installation conditions, the continuous hot air blown out by the fan may cause new safety hazards.

[0006] Therefore, we propose to develop a new type of network engineering junction box, aiming to solve the safety hazards caused by heat accumulation in cables through physical structure design. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model proposes a junction box for network engineering, which ensures that the junction boxes are tightly and dispersed, preventing heat from accumulating and thus reducing safety hazards.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A junction box for network engineering includes a box body and a cover, which are detachably connected. The box body and cover have inlet and outlet holes at their front and rear ends, respectively. The box also includes a sliding plate with multiple sliding grooves running through it. A sliding groove I is located in the center of the sliding plate, and multiple sliding grooves II with varying spacing are symmetrically distributed on both sides of sliding groove I. The sliding groove I and adjacent sliding groove II have equal spacing near the inlet hole, and the distance between the sliding groove I and adjacent sliding groove II near the inlet hole is equal to the distance between the adjacent sliding groove II at the outlet hole. The distance between the ends near the inlet hole and the distance between adjacent slide grooves II near the outlet hole are positively correlated with the distance between slide grooves I and II. Furthermore, the distance between adjacent slide grooves II near the outlet hole is greater than the distance between slide grooves I and II near the outlet hole, and the distance between slide grooves I and II near the outlet hole is greater than the distance between slide grooves I and II near the inlet hole. Each slide groove contains a follower shaft, and a mating block is fixedly connected to its upper end. The mating block has a receiving groove on its upper end. The branch line can be inserted into the receiving groove.

[0010] Furthermore, a limiting housing is provided at the upper end of the slide plate. The upper and lower ends of the limiting housing are open structures, and multiple mating blocks are inserted into the limiting housing. The limiting housing is slidably connected to the box body. The open design at the upper and lower ends of the limiting housing facilitates easy insertion of the mating blocks.

[0011] Furthermore, each of the left and right ends of the limiting housing has a through hole, into which a positioning rod is inserted. Each positioning rod is detachably connected to the housing, and a compression spring is sleeved on the outside of each positioning rod. Each compression spring is located on the side of the limiting housing near the inlet hole, and its two axial ends abut against the inner wall of the housing and the limiting housing, respectively. By setting the compression spring, the required elasticity and positioning function are ensured.

[0012] Furthermore, a damping plate is provided at the upper end of the limiting housing. The damping plate abuts against the upper surface of the mating block, and the damping plate is magnetically connected to multiple mating blocks. By limiting the contact between the damping plate and the upper surface of the mating block, the required resistance is provided to ensure sufficient frictional resistance between the mating block and the branch line.

[0013] Furthermore, the left and right ends of the limiting housing are respectively provided with limiting grooves, and the left and right ends of the damping plate are respectively provided with limiting blocks that cooperate with the limiting grooves, and the limiting blocks are inserted into the limiting grooves.

[0014] Furthermore, an elastic pad is fixedly connected to the inside of the box cover, and the elastic pad abuts against the upper surface of the damping plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a sliding plate inside the housing with multiple grooves. By limiting the distance between adjacent grooves to achieve the desired effect, the design allows the follower shaft to simultaneously pull the branch wires towards the outlet hole and separate adjacent branch wires as the mating block moves towards the outlet hole. This design ensures the branch wires are taut and dispersed, preventing heat accumulation and thus reducing safety hazards. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, terms such as "upper," "lower," "front," and "rear" are used based on the accompanying drawings and are intended to simplify the description rather than limit the actual location of the device or component. These terms are for ease of understanding only and should not be considered as limitations on the embodiments of this utility model.

[0024] Please refer to Figure 1 A junction box for network engineering includes a box body 4 and a cover 1, wherein the box body 4 and the cover 1 are detachably connected. It is worth noting that in practical applications, the box body 4 and the cover 1 are detachably connected using bolts; therefore, both are designed with corresponding bolt holes.

[0025] Meanwhile, the front and rear ends of the box body 4 and the box cover 1 are respectively provided with inlet holes 5 and outlet holes 6, which facilitates the convenient introduction and exit of wires.

[0026] See Figure 2 As shown, compared to the existing technology, the junction box has an additional sliding plate 2, which has multiple through sliding grooves.

[0027] Specifically, the chute design includes a central chute I8 and multiple symmetrically distributed chute II7s on the left and right sides.

[0028] See Figure 2 , Figure 3 , Figure 4 To ensure the stability of the branch line position, the device is equipped with multiple mating blocks 13 inside the housing 4. Each mating block 13 has a receiving groove 14 at its upper end, into which the branch line can be inserted.

[0029] In addition, to ensure that the branch lines maintain an appropriate distance and prevent heat accumulation due to excessive distance, a follower shaft 16 is fixedly installed at the lower end of each mating block 13, and the multiple follower shafts 16 are ensured to correspond one-to-one with the corresponding slide grooves.

[0030] This structure allows for a variable design by adjusting the spacing between slides II7, where the spacing between slide I8 and adjacent slides II7 at the inlet hole 5 is consistent. Simultaneously, it ensures that the distance between adjacent slides II7 at the outlet hole 6 increases with the increase in their distance from slide I8, and this distance is greater than the distance between slides I8 at the same position. When the distance between slide I8 and adjacent slides II7 at the outlet hole 6 is greater than that at the inlet hole 5, the distance between the mating block 13 and the inlet hole 5 can be increased, and the spacing between adjacent branch lines can be widened, thereby achieving branch line contraction and spacing control.

[0031] In addition, to ensure that the distance of the mating block 13 can be adjusted as needed, a limiting housing 10 is added to the upper end of the slide plate 2. The upper and lower ends of the housing are open to facilitate easy insertion of the mating block 13.

[0032] By ensuring that multiple mating blocks 13 are inserted into the limiting housing 10 together, and that the limiting housing 10 and the box 4 are connected by a sliding connection, the technical goal of moving multiple mating blocks 13 simultaneously is achieved. This design can fully utilize the spacing variation function of multiple sliding grooves Ⅱ7.

[0033] Specifically, in order to achieve a sliding connection between the limiting housing 10 and the box 4, this device provides a through hole 15 at each of the left and right ends of the limiting housing 10, and a positioning rod 11 is embedded in the through hole 15.

[0034] In this case, if each positioning rod 11 maintains a relatively fixed relationship with the box 4, the linear movement of the limiting housing 10 can be achieved through the positioning rod 11, ensuring that the movement trajectory of the limiting housing 10 meets expectations.

[0035] Specifically, such as Figure 3 As shown, the positioning rod 11 is positioned precisely by means of the pre-set bolt holes on the box body 4, combined with the support of the box body 4 and the box cover 1 on the end of the positioning rod 11.

[0036] Furthermore, this device is equipped with a compression spring 12 on the outer side of each positioning rod 11 to ensure the required elasticity and positioning function. Each compression spring 12 is positioned on the side of the limiting housing 10 near the inlet hole 5, with both ends of the spring tightly fitted against the inner wall of the housing 4 and the limiting housing 10, thereby causing the limiting housing 10 to tend to move towards the outlet hole 6. This ensures that in actual operation, when the mating block 13 is fixed relative to the corresponding branch line, the mating block 13 can pull the branch line towards the inlet hole 5, thus ensuring the branch line is taut and maintaining an appropriate distance between adjacent branch lines.

[0037] Specifically, to ensure the stability between the mating block 13 and the branch line, and to ensure that the mating block 13 can pull the branch line to move synchronously when it moves toward the outlet hole 6, a damping plate 3 is added to the top of the limiting housing 10. By limiting the contact between the damping plate 3 and the upper end face of the mating block 13, the required resistance is provided to ensure that there is sufficient frictional resistance between the mating block 13 and the branch line to achieve synchronous movement.

[0038] Specifically, in order to ensure that the damping plate 3 continues to move toward the mating block 13, thereby providing sufficient clamping force for the branch line and realizing the frictional connection between the branch line and the mating block 13, this device fixes the damping plate 3 and multiple mating blocks 13 to each other through magnetic connection.

[0039] Furthermore, the device has limit grooves 17 at both ends of the limiting housing 10, and limit blocks that cooperate with the limit grooves 17 are provided at both ends of the damping plate 3. The precise insertion of the limit blocks into the limit grooves 17 stabilizes the positioning of the damping plate 3, while ensuring that the damping plate 3 and the multiple mating blocks 13 achieve the maximum contact area, thereby improving the stability of the overall structure.

[0040] Furthermore, to ensure that the mating block 13 can provide sufficient limiting effect on the branch line during actual use and prevent relative displacement between the branch line and the mating block 13, this device is provided with an elastic pad 9 on the inside of the cover 1. The elastic pad 9 abuts against the upper end face of the damping plate 3. When the cover 1 and the box body 4 are tightly closed, this design provides additional cushioning and enhances the sealing effect.

[0041] In the practical application of this utility model:

[0042] By adding a sliding plate 2 inside the housing 4 and utilizing multiple sliding grooves on the sliding plate 2, the spacing between adjacent sliding grooves is limited, causing the distance between the follower shafts 16 located within the sliding grooves to gradually increase as they move towards the cable outlet 6. This design works in conjunction with the damping plate 3, and in practical applications, it can synchronously pull the branch lines towards the cable outlet 6, effectively separating adjacent branch lines, achieving both tension and dispersion of the branch lines, and achieving the desired technical effect.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
