Description

Technical Field

[0001] This utility model relates to the field of cable junction box technology, and in particular to an anti-interference cable junction box for 10kV user projects. Background Technology

[0002] A cable junction box is a device used to connect, branch, splice, and switch circuits in cable lines, and is mostly used outdoors. It primarily performs the functions of collecting and connecting cable lines in a power distribution system, but does not have secondary auxiliary configurations such as control and measurement functions.

[0003] Cable junction boxes can be divided into two categories according to their electrical composition: one is a common junction box that does not contain any switching equipment, and only contains accessories for processing and connecting cable ends. It has a simple structure, small size, and single function; the other is a high-end junction box that contains switching equipment. It has a complex structure, large size, many connecting devices, high manufacturing difficulty, and high cost.

[0004] Existing cable junction boxes include a box body, a door, and a component mounting plate. The component mounting plate is fixed inside the box for the installation and wiring of relevant electrical components. The box body also has ventilation holes on the side for heat dissipation of the internal components. However, it has the following disadvantages:

[0005] 1. The fixed position of the component mounting plate makes it inconvenient for the installation and wiring of electrical components, and also inconvenient for subsequent maintenance and repair;

[0006] 2. The size of the heat dissipation holes is constant, making it impossible to flexibly control the temperature inside the enclosure.

[0007] This utility model addresses these issues by proposing an anti-interference cable junction box for 10kV user projects. The aim is to solve the aforementioned problems, making the cable junction box easy to install electrical components and wires, convenient for subsequent maintenance and repair, and allowing for flexible control of the temperature inside the box. Utility Model Content

[0008] To address the aforementioned shortcomings in the existing technology, this utility model provides an anti-interference cable junction box for 10kV user engineering projects.

[0009] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0010] An anti-interference cable junction box for 10kV user engineering projects includes a box body and a door, wherein the door is hinged to one side of the box body opening.

[0011] The enclosure contains a component mounting plate, which is connected to the back of the enclosure via a connecting assembly.

[0012] The connecting assembly includes a connecting plate 1, a connecting plate 2, a support plate 1, and a support plate 2. The support plate 1 is symmetrically arranged on the back of the housing, and the support plate 2 is symmetrically arranged on the back of the component mounting plate. The connecting plate 1 is hinged to the outside of the support plate 1, and the connecting plate 2 is hinged to the end of the connecting plate 1 away from the support plate 1. The end of the connecting plate 2 away from the connecting plate 1 is hinged to the support plate 2.

[0013] The inner surface of the side of the housing is provided with a guide and positioning component, which limits the movement direction and position of the connecting component, thereby limiting the movement position of the component mounting plate;

[0014] The lower end of the side of the box is provided with heat dissipation holes, and the inner surface of the side of the box is provided with heat dissipation hole adjustment components;

[0015] The enclosure and door are coated with a shielding coating.

[0016] As an improvement, the guide positioning component includes an arc-shaped guide groove and a positioning hole. The arc-shaped guide groove is provided with a positioning hole, and a positioning rod is slidably connected in the positioning hole. The front end of the positioning rod is slidably connected to the arc-shaped guide groove, and the positioning rod is slidably connected to the hinge joint of connecting plate one and connecting plate two.

[0017] As an improvement, the arc-shaped guide groove is provided with at least three positioning holes, which are evenly distributed within the arc-shaped guide groove.

[0018] As an improvement, the heat dissipation hole adjustment assembly includes an electric push rod and a sealing plate. The sealing plate is provided with through holes evenly distributed. The inner surface of the side of the box is provided with a sliding groove corresponding to the position of the heat dissipation hole. The sealing plate is slidably connected to the sliding groove. An electric push rod is provided below the sliding groove on the inner surface of the side of the box. The piston rod of the electric push rod is connected to the sealing plate.

[0019] As an improvement, a limiting strip is provided on the inner surface of the side of the slide, and the sealing plate is slidably connected to the limiting strip.

[0020] As an improvement, guide strips are symmetrically provided on the inner surface of the upper end face of the housing, and the component mounting plate is slidably connected to the guide strips.

[0021] Compared to traditional technologies, the advantages of this utility model are:

[0022] 1. The component mounting plate is connected to the housing through the connecting components. The guide and positioning components limit the movement direction and position of the connecting components, thereby limiting the movement position of the component mounting plate. This allows the position of the component mounting plate to be flexibly adjusted, facilitating component installation and wiring, and also making subsequent maintenance and repair easier.

[0023] 2. The heat dissipation hole adjustment component allows for flexible adjustment of the size of the channel connecting the heat dissipation holes to the inside and outside of the cabinet, thereby flexibly adjusting the temperature inside the cabinet and ensuring its normal operation.

[0032] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model.

[0033] Example 1

[0034] Combined with appendix Figure 1-3 The housing 1 is provided with a component mounting plate 3, which is connected to the back of the housing 1 via a connecting assembly;

[0035] The connecting assembly includes a first connecting plate 4, a second connecting plate 5, a first supporting plate 6, and a second supporting plate 7. The first supporting plate 6 is symmetrically arranged on the back of the housing 1, and the second supporting plate 7 is symmetrically arranged on the back of the component mounting plate 3. The first connecting plate 4 is hinged to the outside of the first supporting plate 6, and the second connecting plate 5 is hinged to the end of the first connecting plate 4 away from the first supporting plate 6. The end of the second connecting plate 5 away from the first connecting plate 4 is hinged to the second supporting plate 7.

[0036] The inner surface of the side of the housing 1 is provided with a guide and positioning component, which limits the movement direction and position of the connecting component, thereby limiting the movement position of the component mounting plate 3;

[0037] The guide positioning assembly includes an arc-shaped guide groove 9 and a positioning hole 10. The arc-shaped guide groove 9 is provided with a positioning hole 10. A positioning rod 11 is slidably connected in the positioning hole 10. The front end of the positioning rod 11 is slidably connected to the arc-shaped guide groove 9. The positioning rod 11 is slidably connected to the hinge of the connecting plate 4 and the connecting plate 5.

[0038] The inner surface of the upper end face of the housing 1 is symmetrically provided with guide strips 16, and the component mounting plate 3 is slidably connected to the guide strips 16.

[0039] When in use, pulling the positioning rod 11 guides the movement direction of the arc-shaped guide groove 9. The positioning rod 11 drives the connecting plate 4, which is hinged to the support plate 6, to swing forward. The connecting plate 4 drives the connecting plate 5, which is hinged to it, to swing forward. The connecting plate 5 drives the component mounting plate 3 to move outward along the guide strip 16 through the support plate 7, which facilitates the installation and wiring of electrical components on the component mounting plate 3, and also facilitates the maintenance and repair of electrical components.

[0040] After the component mounting plate 3 is positioned, push the positioning rod 11 so that the end of the positioning rod 11 facing the side plate of the housing 1 is inserted into the positioning hole 10 in the arc-shaped guide groove 9 to achieve the positioning of the component mounting plate 3.

[0041] Combined with appendix Figure 3 The arc-shaped guide groove 9 is provided with at least three positioning holes 10, which are evenly distributed within the arc-shaped guide groove 9; the box body 1 and the box door 2 are coated with shielding paint.

[0042] The three positioning holes 10 within the arc-shaped guide groove 9 provide at least three fixed positions for the component mounting plate 3, facilitating different operations. The shielding coating applied to the enclosure 1 and the door 3 ensures that the junction box has excellent electromagnetic shielding performance.

[0043] Example 2

[0044] Combined with appendix Figure 1-4The lower side of the box 1 is provided with a heat dissipation hole 8, and the inner surface of the side of the box 1 is provided with a heat dissipation hole adjustment component.

[0045] The heat dissipation hole adjustment assembly includes an electric push rod 12 and a sealing plate 13. The sealing plate 13 is provided with through holes evenly. The inner surface of the side of the box 1 is provided with a sliding groove 14 corresponding to the position of the heat dissipation hole 8. The sealing plate 13 is slidably connected to the sliding groove 14. The electric push rod 12 is provided below the sliding groove 14 on the inner surface of the side of the box 1. The piston rod of the electric push rod 12 is connected to the sealing plate 13.

[0046] The inner surface of the side of the slide groove 14 is provided with a limiting strip 15, and the sealing plate 13 is slidably connected to the limiting strip 15.

[0047] Based on Embodiment 1, the piston rod of the electric push rod 12 extends and retracts, causing the sealing plate 13 to move within the slide groove 14. The limiting strip 15 on the side of the slide groove 14 guides the movement direction of the sealing plate 13 and prevents it from moving out of the slide groove 14. By adjusting the overlap between the through hole and the heat dissipation hole 8 on the sealing plate 13, the size of the channel connecting the inside and outside of the box 1 is adjusted, thereby flexibly controlling the temperature inside the box 1.

[0048] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
