Description

Technical Field

[0001] This invention relates to the field of switch box wiring technology, specifically to a quick wiring device for switch boxes. Background Technology

[0002] A switch box is a base box used to fix switch or socket panels. Its main function is to house electrical connection components and ensure safe wiring. Switch boxes play an important role in power plants. As an important component of the power plant's power distribution system, they cover multiple aspects such as power control, protection, isolation, and operation control. The side of the switch box is usually provided with wiring holes, and the wiring holes are provided with wires for connecting corresponding electronic devices in the plant.

[0003] When using existing quick-connection devices for switch boxes, operators typically use terminal blocks to connect the wires of electronic components to the wires of the switch box. However, during the connection process, due to the lack of an initial positioning structure for the wires, the wires may often come loose from the wiring holes before they are secured by screws. Operators often need to repeatedly insert the wires to achieve the connection, which is not conducive to the wire connection work in the switch box. Summary of the Invention

[0004] The purpose of this invention is to provide a quick wiring device for switch boxes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick wiring device for a switch box, comprising:

[0006] The mounting housing has a transmission cavity inside, and the transmission cavity has an anti-loosening component that can initially position the wires before they are connected.

[0007] Four receiving slots are symmetrically arranged at both ends of the mounting shell. An arc-shaped seat is fixedly connected to one side port of each receiving slot. A clamping component for stable wire connection is provided inside each receiving slot.

[0008] Preferably, the anti-loosening component includes a ball screw disposed inside the transmission cavity. The ball screw is rotatably connected to both ends of the inner wall of the transmission cavity. A screw nut block is helically connected to the outer side of the ball screw. A positioning rod is provided inside the receiving groove. A gear is fixedly connected to the top of the positioning rod. A rack is provided on one side of the gear. The bottom end of the rack is connected to the screw nut block. One side of the rack meshes with the gear. An arc plate is fixedly connected to the bottom end of the positioning rod and the top of the arc seat.

[0009] Preferably, a drive shaft is coaxially fixedly connected inside the gear, and the drive shaft is connected to both sides of the inner wall of the receiving groove.

[0010] Preferably, sliders are fixedly connected to both sides of the wire block, and grooves corresponding to the sliders are opened on both sides of the inner wall of the receiving groove, with the sliders located inside the grooves.

[0011] Preferably, the inner wall of the arc-shaped plate is provided with intermittently spaced friction ridges, which are made of rubber or silicone material.

[0012] Preferably, the top end of the ball screw extends through the outside of the receiving groove and is fixedly connected to an internal hexagonal protrusion.

[0013] Preferably, the clamping assembly includes a power connector fixed to the bottom of the cavity of the receiving groove. The power connector has a wiring hole inside, and the bottom of the wiring hole has an internal thread groove. A clamping screw is spirally connected inside the internal thread groove.

[0014] Preferably, a connecting strip is provided between the connecting bases, and a mounting groove corresponding to the connecting strip is opened inside the mounting shell.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-6 As shown, a quick-connection device for a switch box includes a mounting housing 1. The mounting housing 1 has a transmission cavity 3 inside, and the transmission cavity 3 has an anti-loosening component 4 inside, which can initially position the wires before connection. By setting the anti-loosening component 4, the wires can be positioned and fixed from the outside of the connection end before the operator connects the electronic component wires to the switch box wires. This effectively improves the tensile strength of the wires and prevents them from coming loose due to pulling before they are properly secured with screws. This avoids the operator having to repeatedly insert the wires, thus improving wiring efficiency and effectiveness. (Four capacities...) The receiving slots 2 are symmetrically arranged at both ends of the mounting shell 1. An arc-shaped seat 9 is fixedly connected to one side port of the receiving slot 2. The receiving slot 2 is equipped with a clamping component 11 for stable wire connection. By setting the clamping component 11, after the initial positioning of the wires to be connected is completed, it is convenient for the staff to clamp and fix the electronic device wires and switch box wires to the bottom of the inner cavity of each receiving slot 2. This enables quick connection between the electronic device wires and switch box wires. Compared with the traditional wiring method, it reduces the wiring difficulty, reduces the workload of the staff, and is more suitable for the situation of a large number of wiring points in the power plant.

[0028] The anti-loosening component 4 includes a ball screw 41 disposed inside the transmission cavity 3. The ball screw 41 is rotatably connected to both ends of the inner wall of the transmission cavity 3. A screw nut block 42 is helically connected to the outer side of the ball screw 41. A positioning rod 45 is provided inside the receiving groove 2. A gear 44 is fixedly connected to the top of the positioning rod 45. A rack 43 is provided on one side of the gear 44. The bottom end of the rack 43 is connected to the screw nut block 42, and one side of the rack 43 meshes with the gear 44. An arc plate 46 is fixedly connected to the bottom end of the positioning rod 45 and the top of the arc seat 9. Figure 5 , Figure 6 As shown, it should be noted that the screw nut 42 is internally fitted with a screw nut that matches the ball screw 41. When the ball screw 41 rotates, the screw nut 42 slides back and forth along the axis of the ball screw 41. In actual use, when it is necessary to connect electronic device wires and switch box wires, the electronic device wires and switch box wires can be inserted into the corresponding receiving slots 2 in advance. Then, the ball screw 41 drives the screw nut 42 to move downward along the inner wall of the transmission cavity 3. During the movement of the screw nut 42, the racks 43 set at its four corners will drive the adjacent gears 44 to rotate. The rotation of the gears 44 will then drive the positioning rod 45 to fall and reach the position above the arc-shaped seat 9. At this time, the electronic device wires and switch box wires will be connected by the bottom end of the positioning rod 45 and the arc-shaped seat 9. The adjacent arc-shaped plates 46 at the top are positioned and fixed, thereby improving the anti-loosening performance of the wires and enabling the wires to effectively resist the pulling and dragging during the wiring process. This prevents the wires from coming loose due to pulling before they are properly secured by screws, avoiding repeated wire insertion operations by the staff. This improves wiring efficiency and wiring effect. When it is necessary to inspect and maintain the wires of electronic components and switch boxes, the ball screw 41 can be used to drive the nut block 42 to move upward along the inner wall of the transmission cavity 3. Then, with the cooperation between the rack 43 and the gear 44, the positioning rod 45 can be driven to rise and move away from the arc-shaped seat 9. At this time, the top of the inner cavity of the receiving groove 2 is completely exposed to the staff's line of sight, which facilitates the subsequent inspection and maintenance of the wires of electronic components and switch boxes and effectively improves practicality.

[0029] A drive shaft 7 is coaxially fixedly connected inside the gear 44. The drive shaft 7 is connected to both sides of the inner wall of the receiving groove 2, such as... Figure 3 , Figure 5 As shown, the drive shaft 7 is coaxially arranged inside each gear 44. By setting the drive shaft 7, the positioning rod 45 can be limited as a whole. When the gear 44 rotates due to its cooperation with the rack 43, the positioning rod 45 can be flipped up or down with the drive shaft 7 as the center. This facilitates the positioning of electronic device wires and switch box wires, and also facilitates the later inspection and maintenance of electronic device wires and switch box wires, thus improving the working stability of the anti-loosening component 4.

[0030] Both sides of the nut block 42 are fixedly connected to sliders 5, and both sides of the inner wall of the receiving groove 2 are provided with grooves 6 corresponding to the sliders 5. The sliders 5 are located inside the grooves 6, such as... Figure 5 , Figure 6 As shown, by setting the slider 5 and the slide groove 6, on the one hand, the screw nut block 42 can be limited to prevent the screw nut block 42 from rotating together with the ball screw 41, which would cause the anti-loosening component 4 to fail to work. On the other hand, the screw nut block 42 can be kept smooth during the lifting and sliding process, thus further improving the working stability of the anti-loosening component 4.

[0031] The inner wall of the arc-shaped plate 46 is provided with intermittently spaced friction ridges 10, which are made of rubber or silicone material. Figure 3 , Figure 4 and Figure 6 As shown, by intermittently and equally spaced friction ridges 10 on the inner walls of each arc plate 46, the friction between the outer sheath of the electronic device wires and the outer sheath of the switch box wires and the inner wall of the arc plate 46 can be effectively enhanced. This further improves the anti-loosening performance of the wires, making them less likely to come loose due to external pulling or dragging. At the same time, the friction ridges 10 are made of rubber or silicone, which are relatively soft and can prevent the sharp edges of the arc plate 46 from scratching the outer sheath of the electronic device wires and switch box wires, thus providing a certain degree of protection and further improving practicality.

[0032] The top end of the ball screw 41 extends through to the outside of the receiving groove 2 and is fixedly connected to an internal hexagonal protrusion 8, such as... Figure 2 , Figure 4 and Figure 5 As shown, the groove on the top of the hexagonal protrusion 8 matches the commonly used hexagonal wrench. When workers need to connect the wires of electronic components and switch boxes, they can use the corresponding hexagonal wrench to drive the hexagonal protrusion 8 to rotate from the outside of the receiving groove 2. Then, the hexagonal protrusion 8 drives the ball screw 41 to rotate. The ball screw 41 then drives its outer nut block 42 to move downward along the inner wall of the transmission cavity 3. Then, through the cooperation between the rack 43 and the gear 44, the positioning rods 45 inside the four receiving grooves 2 can be driven to fall down at the same time, which facilitates the connection of the wires of electronic components and switch boxes.

[0033] The clamping assembly 11 includes a power connector 111 fixed to the bottom of the inner cavity of the receiving groove 2. The power connector 111 has a wiring hole 112 inside, and an internal threaded groove 113 is formed at the bottom of the inner cavity of the wiring hole 112. A clamping screw 114 is screwed into the internal threaded groove 113. Figure 2 , Figure 3 and Figure 5As shown, in actual use, after the wires of various electronic components and switch boxes are inserted into the corresponding wiring holes 112, the initial positioning of the wires to be connected can be completed by the anti-loosening component 4. At this time, the wires of electronic components and switch boxes will be positioned and fixed by the bottom end of the positioning rod 45 and the adjacent arc plate 46 on the top of the arc seat 9, so that the wires can effectively resist the pulling and pulling during the wiring process. After the initial positioning of the wires to be connected is completed, the operator can use a screwdriver to drive the clamping screw 114 inside the internal thread groove 113 to rotate. Since the internal thread groove 113 and the clamping screw 114 are threadedly engaged, as the clamping screw 114 rotates continuously, the clamping screw 114 will gradually penetrate into the wiring hole 112 inside the connector 111 until it is pressed in. The threaded end of the tightening screw 114 firmly presses and fixes the electronic component wires and switch box wires inside the corresponding wiring hole 112. At this time, the electronic component wires and switch box wires cannot be pulled out from the wiring hole 112 because the connection end is fixed. This achieves quick connection between the electronic component wires and switch box wires. It should be noted that in order to prevent leakage caused by contact between the tightening screw 114 and the electronic component wires and switch box wires, the tightening screw 114 should be made of a hard plastic or other insulating material. This can effectively prevent unstable and unsafe power supply to the electronic component wires and switch box wires due to leakage without hindering the connection between the electronic component wires and switch box wires, thus enhancing the safety of the electronic component wires and switch box wires.

[0034] A connecting strip 13 is provided between the connecting bases 111. The mounting housing 1 has an internal mounting groove 12 corresponding to the connecting strip 13. The connecting strip 13 is fixedly installed inside the mounting groove 12 and is connected to the connecting bases 111 at both ends. Figure 5 As shown, it should be noted that the grounding base 111 and the grounding strip 13 can be made of common conductive metal materials such as copper, while the mounting shell 1 can be made of plastic material. The grounding strip 13 is set between the opposing grounding bases 111. The grounding strip 13 is connected to the outside of the grounding bases 111 at both ends through the mounting groove 12, so as to realize the power flow of the wires inside the opposing wiring holes 112, and thus realize the power flow between the wires of electronic devices and the wires of switch boxes.

[0035] The axis of the wiring hole 112 and the arc-shaped seat 9 are in the same plane, such as... Figure 3 , Figure 5As shown, in actual use, to prevent bending of the connection ends of electronic device wires and switch box wires due to inconsistent positions of wiring hole 112 and arc-shaped seat 9 during the connection process, wiring hole 112 should be in the same plane as the axis of arc-shaped seat 9. That is, arc-shaped seat 9 and wiring hole 112 should be coaxial. This avoids excessive bending of electronic device wires and switch box wires, which is conducive to the normal operation of clamping assembly 11 and facilitates the connection between electronic device wires and switch box wires.

[0036] Positioning seats 14 are fixedly connected to the four corners of the bottom of the mounting shell 1, such as Figure 1 , Figure 2 As shown, by setting positioning seats 14 at the four corners of the bottom of the mounting shell 1, and then using tools and fasteners such as bolts, the workers can easily install the invention on the wall or frame according to actual usage needs, which helps to improve the overall installation stability of the mounting shell 1.

[0037] Working Principle: First, the operator strips the outer sheath of one end of the wires from the electronic components and switch boxes to be connected and inserts them into the corresponding wiring holes 112. When it is necessary to connect the wires, the anti-loosening component 4 can drive multiple positioning rods 45 to fall synchronously and reach the position above the arc-shaped base 9. At this time, the wires are positioned and fixed by the bottom of the positioning rods 45 and the adjacent arc-shaped plates 46 on the top of the arc-shaped base 9, thereby improving the anti-loosening performance of the wires. This allows the wires to effectively resist the pulling and dragging during the wiring process, preventing the wires from coming loose before they are tightened by the screws. This avoids the operator having to repeatedly insert the wires, which is beneficial for improving the connection efficiency. The wiring efficiency and effect are improved. At the same time, the friction ridges 10 can effectively enhance the friction between the outer sheath of the electronic device wires and the outer sheath of the switch box wires and the inner wall of the arc plate 46. This can further improve the anti-loosening performance of the wires. The electronic device wires and switch box wires are less likely to come loose due to external pulling or pulling. After the initial positioning of the wires to be connected is completed, the pressing component 11 can drive the threaded end of the pressing screw 114 to tightly press and fix the electronic device wires and switch box wires into the corresponding wiring holes 112. At this time, the electronic device wires and switch box wires cannot be pulled out from the wiring holes 112 because the connection end is fixed. Thus, the quick connection between the electronic device wires and the switch box wires is realized.
