Description

Technical Field

[0001] This utility model relates to the field of switch box technology, specifically to an outdoor switch box with a bare wire protective cover. Background Technology

[0002] Outdoor switch boxes are critical electrical installations used to control and protect electrical equipment, and are widely used in the power, telecommunications, and industrial sectors. Their primary function is to control and protect systems through switches, circuit breakers, and various protective devices to ensure the safe and stable operation of electrical equipment. In outdoor environments, switch boxes must be able to withstand various weather conditions and operating conditions; therefore, their design requires high levels of weather resistance and protective capabilities.

[0003] To connect to external power sources and electrical equipment, outdoor switch boxes are structurally equipped with openings for wires to enter and exit, typically including one inlet and one or more outlet holes. The inlet hole is used to bring the power cord into the box, while the outlet holes are used to distribute power from inside the box to external equipment. However, the wire portions of these inlet and outlet holes are usually exposed on the outside of the switch box. Because these exposed wires are directly exposed to the environment, they are highly susceptible to damage from wind, rain, human forces, or animals, increasing the risk of wire damage.

[0004] When these exposed wires are pulled by external forces, the connections inside the box can easily become loose. This can lead to power system malfunctions such as unstable circuits, power outages, or even short circuits, thus creating safety hazards. It not only affects the normal operation of electrical equipment but may also pose a risk of electric shock. Therefore, we propose outdoor switch boxes with protective covers for exposed wires. Utility Model Content

[0005] The purpose of this invention is to provide an outdoor switch box with a bare wire protective cover to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An outdoor switch box with a bare wire protective cover includes a switch box body. The bottom of the switch box body has multiple wire passage holes arranged equidistantly from left to right. The switch box body is the main frame of the entire device, supporting other components, and allows wires to enter and exit through the wire passage holes at its bottom. A rectangular protective cover is detachably connected to the bottom of the switch box body. The multiple wire passage holes are all located inside the rectangular protective cover to protect the wires passing through the wire passage holes and prevent direct damage to the wires from external forces.

[0008] The rear side of the inner wall of the rectangular protective cover is provided with multiple fixed vertical plates arranged at equal intervals from left to right. The number of fixed vertical plates is the same as the number of wire holes. The front side of the rectangular protective cover is movably connected with multiple clamping main components arranged at equal intervals from left to right. The clamping main components include a first bolt pressure rod threaded to the front side of the rectangular protective cover. The rear end of the first bolt pressure rod passes through the front side of the rectangular protective cover and is rotatably connected to a movable vertical plate. The multiple movable vertical plates are respectively located in front of the multiple fixed vertical plates. The first bolt pressure rod drives the movable vertical plates to move back and forth. When the movable vertical plate moves backward, it can clamp the electrical components between the movable vertical plate and the fixed vertical plate. When the exposed wires are pulled by external force, the movable vertical plate and the fixed vertical plate can fix the wires, preventing the wires from detaching from the connection end of the equipment inside the switch box and improving safety.

[0009] The front side of the movable vertical plate is provided with two positioning rods arranged symmetrically at the top and bottom. The front end of the positioning rods penetrates the front side of the inner wall of the rectangular protective cover to the outside, ensuring that the movable vertical plate moves stably back and forth, so that the movable vertical plate is stably driven by the first bolt pressure rod.

[0010] Preferably, the top of the outer wall of the rectangular protective cover is provided with a frame-shaped mounting plate, and the bottom of the frame-shaped mounting plate is provided with multiple mounting holes. Bolts are connected in the mounting holes and the bolts are threaded to the bottom of the switch box body to ensure a stable connection between the frame-shaped mounting plate and the switch box body, which facilitates the assembly and disassembly of the rectangular protective cover.

[0011] Preferably, the height of the fixed vertical plate is two-thirds of the height of the rectangular protective cover, and the bottom of the fixed vertical plate is on the same plane as the bottom of the rectangular protective cover, so that space is reserved above the fixed vertical plate, which is beneficial for the wires to move closer to the front side of the fixed vertical plate.

[0012] Preferably, a first arc-shaped groove is provided on the front side of the fixed vertical plate, and a second rubber pad is adhered in the first arc-shaped groove to increase the friction between the wire and the fixed vertical plate and improve the stability of pressing the wire.

[0013] Preferably, the front end of the first bolt lever is provided with a first knob, which is used to rotate the first bolt lever, making it convenient for the operator to rotate the first bolt lever.

[0014] Preferably, the height of the movable vertical plate is the same as the height of the fixed vertical plate, and a second arc-shaped groove is provided on the rear side of the movable vertical plate. A first rubber pad is adhered in the second arc-shaped groove to increase the friction between the wire and the movable vertical plate and improve the stability of pressing the wire.

[0015] Preferably, the rectangular protective cover is provided with clamping accessories on the front side and near the upper and lower sides of the clamping main component. The clamping accessories include a strip-shaped fixing plate fixedly connected to the front side of the rectangular protective cover. The front side of the strip-shaped fixing plate is threaded with multiple second bolt pressure rods arranged equidistantly from left to right. The number of second bolt pressure rods on the clamping accessories is the same as the number of fixed vertical plates. The rear end of the second bolt pressure rod passes through the front side of the rectangular protective cover and is rotatably connected to a circular pressure block. The rear side of the circular pressure block abuts against the front side of the movable vertical plate. The second bolt pressure rod drives the circular pressure block to move back and forth. When the movable vertical plate clamps the wire, the second bolt pressure rod drives the circular pressure block to move backward, generating a backward squeezing force on the movable vertical plate. This allows the movable vertical plate to generate three squeezing forces on the wire, thereby improving the clamping effect of the movable vertical plate on the wire.

[0016] Preferably, the front end of the second bolt lever is provided with a second knob, which is used to rotate the second bolt lever, making it convenient for the operator to rotate the second bolt lever.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This outdoor switch box with bare wire protective cover effectively secures exposed wires passing through the wire hole through a rectangular protective cover, a fixed vertical plate, and a movable vertical plate. Through the combined action of the fixed and movable vertical plates, and the further pressing action of two clamping accessories, the wires will not easily move or fall off when subjected to external force, enhancing the stability of the electrical connection and avoiding circuit failures and equipment damage caused by loosening.

[0019] 2. This outdoor switch box with bare wire protection cover features a first knob and a second knob design, making operation and installation easier. Workers can easily adjust the first and second bolt levers to quickly fix and adjust the wires, reducing problems caused by misoperation.

[0020] 3. This outdoor switch box with bare wire protective cover increases the friction between the wire and the pressure plate by adding a second rubber pad and a first rubber pad in the arc-shaped groove, further improving the wire clamping effect. This multi-fixing and protective measure greatly reduces the risk of power system failure caused by loose wires and improves the safety performance of the equipment. Attached Figure Description

[0030] Please see Figures 1-6 This utility model provides a technical solution:

[0031] An outdoor switch box with a bare wire protective cover includes a switch box body 1. The bottom of the switch box body 1 has multiple wire passage holes 10 arranged equidistantly from left to right. The switch box body 1 is the main frame of the entire device, supporting other components, and allows wires to enter and exit through the wire passage holes 10 at its bottom. A rectangular protective cover 2 is detachably connected to the bottom of the switch box body 1. The multiple wire passage holes 10 are all located inside the rectangular protective cover 2, which is used to protect the wires passing through the wire passage holes 10 and prevent direct damage to the wires from external forces.

[0032] The rear side of the inner wall of the rectangular protective cover 2 is provided with multiple fixed vertical plates 3 arranged equidistantly from left to right. The number of fixed vertical plates 3 is the same as the number of wire holes 10. The front side of the rectangular protective cover 2 is movably connected with multiple clamping main components 4 arranged equidistantly from left to right. The clamping main component 4 includes a first bolt pressure rod 40 threaded to the front side of the rectangular protective cover 2. The rear end of the first bolt pressure rod 40 passes through the front side of the rectangular protective cover 2 and is rotatably connected to a movable vertical plate 41. The multiple movable vertical plates 41 are located directly in front of the multiple fixed vertical plates 3. The first bolt pressure rod 40 drives the movable vertical plates 41 to move back and forth. When the movable vertical plate 41 moves backward, it can clamp the electrical components between the movable vertical plate 41 and the fixed vertical plates 3. When the exposed wires are pulled by external force, the movable vertical plates 41 and the fixed vertical plates 3 can fix the wires, preventing the wires from detaching from the connection end of the equipment inside the switch box and improving safety.

[0033] The front side of the movable vertical plate 41 is provided with two positioning rods 43 arranged symmetrically at the top and bottom. The front end of the positioning rod 43 penetrates the front side of the inner wall of the rectangular protective cover 2 to the outside, ensuring that the movable vertical plate 41 moves back and forth stably, so that the movable vertical plate 41 is stably driven by the first bolt pressure rod 40.

[0034] In this embodiment, a frame-shaped mounting plate 20 is provided on the top of the outer wall of the rectangular protective cover 2. Multiple mounting holes 200 are provided on the bottom of the frame-shaped mounting plate 20. Bolts 6 are connected in the mounting holes 200. The bolts 6 are threaded to the bottom of the switch box body 1 to ensure a stable connection between the frame-shaped mounting plate 20 and the switch box body 1, which facilitates the assembly and disassembly of the rectangular protective cover 2.

[0035] Specifically, the height of the fixed vertical plate 3 is two-thirds of the height of the rectangular protective cover 2, and the bottom of the fixed vertical plate 3 and the bottom of the rectangular protective cover 2 are on the same plane, so that space is reserved above the fixed vertical plate 3, which is conducive to the wires moving closer to the front of the fixed vertical plate 3.

[0036] Furthermore, a first arc-shaped groove 30 is provided on the front side of the fixed vertical plate 3, and a second rubber pad 7 is adhered in the first arc-shaped groove 30 to increase the friction between the wire and the fixed vertical plate 3 and improve the stability of pressing the wire.

[0037] Furthermore, a first knob 44 is provided at the front end of the first bolt lever 40. The first knob 44 is used to rotate the first bolt lever 40, making it convenient for the operator to rotate the first bolt lever 40.

[0038] Furthermore, the height of the movable vertical plate 41 is the same as that of the fixed vertical plate 3. A second arc-shaped groove 410 is provided on the rear side of the movable vertical plate 41. A first rubber pad 42 is adhered in the second arc-shaped groove 410 to increase the friction between the wire and the movable vertical plate 41 and improve the stability of pressing the wire.

[0039] Furthermore, clamping accessories 5 are provided on the front side of the rectangular protective cover 2 and near the upper and lower sides of the clamping main component 4. The clamping accessories 5 include a strip-shaped fixing plate 50 fixedly connected to the front side of the rectangular protective cover 2. The front side of the strip-shaped fixing plate 50 is threaded with multiple second bolt pressure rods 51 arranged equidistantly from left to right. The number of second bolt pressure rods 51 on the clamping accessories 5 is the same as the number of fixed vertical plates 3. The rear end of the second bolt pressure rod 51 passes through the front side of the rectangular protective cover 2 and is rotatably connected to a circular pressure block 52. The rear side of the circular pressure block 52 abuts against the front side of the movable vertical plate 41. The second bolt pressure rod 51 drives the circular pressure block 52 to move back and forth. When the movable vertical plate 41 clamps the wire, the second bolt pressure rod 51 drives the circular pressure block 52 to move backward, generating a backward squeezing force on the movable vertical plate 41. This allows the movable vertical plate 41 to generate three squeezing forces on the wire, thereby improving the clamping effect of the movable vertical plate 41 on the wire.

[0040] Furthermore, a second knob 53 is provided at the front end of the second bolt lever 51. The second knob 53 is used to rotate the second bolt lever 51, making it convenient for workers to rotate the second bolt lever 51.

[0041] In this embodiment, the outdoor switch box with bare wire protective cover is used by fixing the rectangular protective cover 2 to the bottom of the switch box body 1 through the mounting holes 200 provided on the frame mounting plate 20 using bolts 6, ensuring that all wire holes 10 are inside the rectangular protective cover 2 and allowing the wires to pass through safely. Next, the wires are introduced through the wire holes 10 and arranged between the fixed vertical plates 3, ensuring that the wire length is appropriate for subsequent fixing and adjustment. Then, the contact between the movable vertical plate 41 and the wire is adjusted. By rotating the first knob 44, the first bolt pressure rod 40 is pushed, causing the movable vertical plate 41 to move backward, increasing the friction between the fixed vertical plate 3 and the movable vertical plate 41, effectively fixing the wires. For a tighter effect, the second bolt pressure rod 51 is adjusted, and more pressure is applied to the movable vertical plate 41 through the circular pressure block 52, thereby enhancing the fixing force of the fixed vertical plate 3 and the movable vertical plate 41 on the wires. Finally, the fixing status of all wires is carefully checked to prevent any loosening, thereby greatly reducing the risk of wire failure caused by external forces.
