Description

Technical Field

[0001] The present application relates to the technical field of wire arrangement in distribution cabinets, and in particular to a wire harness structure for distribution cabinets. Background Art

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the end-level equipment of the power distribution system. Distribution cabinets are the general term for motor control centers. Distribution cabinets are used in occasions where the load is relatively scattered and the number of circuits is small; motor control centers are used in occasions where the load is concentrated and the number of circuits is large. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring, and control for the load;

[0003] Due to the complex internal wiring of distribution cabinets, in order to make the wiring more intuitive and convenient for later maintenance, the wiring needs to be arranged. The existing methods include restraining the wires through U-shaped elastic clips, which is convenient to operate but prone to falling off; there is also restraint in the form of cable ties. Although it has high reliability, its operation convenience and the convenience of later maintenance are both poor; there is also a method of fixing through metal sheets and bolts, which requires all wires to be arranged neatly before simultaneous restraint, and the operation difficulty is high;

[0004] To solve the above problems, a wire harness structure for distribution cabinets is proposed in the present application. Utility Model Content

[0005] In order to solve the problem of inconvenient and unreliable wire bundling, the present application provides the following technical solutions.

[0006] A wire harness structure for distribution cabinets provided by the present application includes a fixed seat and a movable seat distributed in parallel with the fixed seat. An arc-shaped seat for ensuring the clamping accuracy and fitting degree of the wire is provided at one end of the movable seat away from the fixed seat. A clamping block for clamping and disengaging the guide is slidably provided on the movable seat. The clamping blocks are symmetrically arranged in pairs on both sides of the arc-shaped seat. The two cooperating clamping blocks clamp the wire through a driving component, and the two cooperating clamping blocks disengage the clamping of the wire through an elastic member, but the minimum gap between the two clamping blocks is always smaller than the wire diameter.

[0007] Preferably, a through hole for the clamping block to penetrate and slide is provided in the movable seat. Sliders are fixedly provided at both the upper and lower ends of the clamping block, and a sliding groove for sliding cooperation with the slider is provided in the through hole of the movable seat.

[0008] Preferably, the driving component includes a pressure-receiving plate integrally connected to the end of the clamping block and a pressing block fixed to one end of the fixed seat close to the movable seat. The pressure-receiving plate and the pressing block are in pressing cooperation. After the pressing block presses the pressure-receiving plate, the two cooperating clamping blocks are driven to approach each other and clamp the wire.

[0009] Preferably, the driving component further includes a clamping bolt rotatably arranged on the fixed seat and a screw sleeve fixedly arranged in the movable seat and in screw fit with the clamping bolt.

[0010] Preferably, a guiding hole is formed in the movable seat, and a guiding rod fixedly arranged on the fixed seat and penetrating and sliding in the guiding hole is provided. A limiting block is fixed at the front end of the guiding rod.

[0011] Preferably, the elastic member is a spring piece, and the clamping block disengages from the clamping of the wire through the spring piece.

[0012] Preferably, a fixing piece for fixing in the power distribution cabinet is fixedly arranged on the fixed seat.

[0013] In summary, the present application includes the following beneficial technical effects:

[0014] Clamping blocks are provided to clamp from both sides. When the clamping blocks are in the fully open state, the gap between two adjacent and cooperating clamping blocks is slightly smaller than the diameter of the wire, and then the wire is squeezed between the two clamping blocks through the original toughness of the wire, playing a role of pre-positioning before clamping; the clamping blocks press the wire through screw drive and the cooperation of the pressure receiving plate and the extrusion block; the pre-positioning and locking of the wire are integrally arranged, having the advantages of convenient operation, high reliability and high linkage.

Detailed Description of the Embodiment

[0021] The following will further describe the present application in detail Figure 1 - Figure 5 with reference to the accompanying drawings.

[0022] Reference Figure 1 - Figure 5 , a wiring harness structure for a power distribution cabinet, including a fixed seat 1 and a movable seat 2 distributed in parallel with the fixed seat 1. An arc-shaped seat 3 for ensuring the clamping accuracy and fitting degree of the wire is provided at one end of the movable seat 2 away from the fixed seat 1. A clamping block 4 for guiding clamping and detachment is slidably provided on the movable seat 2. The clamping blocks 4 are symmetrically arranged in pairs on both sides of the arc-shaped seat 3. The two cooperating clamping blocks 4 clamp the wire through a driving component. The clamping blocks 4 are provided to clamp from both sides. When the clamping blocks 4 are in the fully open state, the gap between two adjacent cooperating clamping blocks 4 is slightly smaller than the diameter of the wire, and then the wire is squeezed between the two clamping blocks 4 by the original toughness of the wire, playing a pre-positioning role before clamping. The two cooperating clamping blocks 4 are detached from clamping the wire through an elastic member, but the minimum gap between the two clamping blocks 4 is always smaller than the diameter of the wire. After the two corresponding clamping blocks 4 are fully opened, since the gap is smaller than the diameter of the wire, the wire will not fall off automatically and needs to be pulled out manually to be removed, ensuring that the wires that are not overhauled and replaced are always in a constrained state.

[0023] Reference Figure 4 , a through hole for the clamping block 4 to penetrate and slide is provided in the movable seat 2. Sliders 5 are fixedly provided at both the upper and lower ends of the clamping block 4. A sliding groove 6 slidably engaged with the slider 5 is opened in the through hole of the movable seat 2. The slider 5 and the sliding groove 6 limit the movement path of the clamping block 4 and the reliability during the movement process, ensuring the structural accuracy and strength.

[0024] Reference Figure 2 - Figure 5 , the driving component includes a pressure-receiving plate 8 integrally connected to the end of the clamping block 4 and a pressing block 9 fixed to one end of the fixed seat 1 close to the movable seat 2. The pressure-receiving plate 8 and the pressing block 9 are in pressing cooperation. After the pressing block 9 presses the pressure-receiving plate 8, the two cooperating clamping blocks 4 are driven to approach each other and clamp the wire. The contact surface between the pressure-receiving plate 8 and the pressing block 9 is inclined. After pressing, the position of the clamping block 4 is changed, playing a role in changing the direction of the force, and improving the operation convenience while ensuring reliable clamping.

[0025] Reference Figure 1 - Figure 5 , the driving component further includes a clamping bolt 10 rotatably provided on the fixed seat 1 and a screw sleeve 11 fixedly provided in the movable seat 2 and in screw fit with the clamping bolt 10. The cooperation of the clamping bolt 10 and the screw sleeve 11 has the advantages of convenient operation and reliable structure.

[0026] Reference Figure 4 - Figure 5, a guiding hole 12 is formed in the movable seat 2, and a guiding rod 13 which penetrates and slides in the guiding hole 12 is fixedly arranged on the fixed seat 1. A limiting block 14 is fixedly arranged at the front end of the guiding rod 13. The cooperation between the guiding hole 12 and the guiding rod 13 plays a role in guiding and strengthening the structure, ensuring the cooperation reliability and precision between the fixed seat 1 and the movable seat 2, and the guiding rod 13 restricts the movement range of the fixed seat 1 and the movable seat 2.

[0027] Refer to Figure 4 , the elastic member is an elastic sheet 7. The clamping block 4 releases the clamping of the wire through the elastic sheet 7. The elastic sheet 7 is used for the opening after the clamping block 4 disengages from the driving component, and the elastic sheet 7 can be replaced by an elastic structure such as a spring.

[0028] Refer to Figure 5 , a fixing piece 15 for fixing in the power distribution cabinet is fixedly arranged on the fixed seat 1. The wire harness structure is fixed in the power distribution cabinet through the fixing piece 15, and the fixing piece 15 can also be replaced by other connecting pieces such as quick buckles.

[0029] Working principle: According to the distribution of the internal lines in the power distribution cabinet, the wire harness structure is fixed in the power distribution cabinet through screws and the fixing piece 15. During the wire arrangement process in the power distribution cabinet, the clamping block 4 is in an open state. At this time, the gap between two cooperating clamping blocks 4 is slightly smaller than the diameter of the wire. The wire is squeezed between the two clamping blocks 4 and the arc-shaped seat 3 through the toughness of the wire. At this time, the wire is pre-positioned. The remaining wires are arranged in sequence. After the arrangement is completed, the straightness of the wires is adjusted, the wires are pulled into a straight state, and then the clamping bolt 10 is rotated. The screw sleeve 11 drives the movable seat 2 to gradually approach the fixed seat 1 through the spiral with the clamping bolt 10. At this time, the extrusion block 9 and the pressure receiving plate 8 are mutually extruded. The extrusion block 9 extrudes and moves the pressure receiving plate 8. The pressure receiving plate 8 moves in the movable seat 2 and drives the slider 5 to move inside the sliding groove 6 accordingly. The guiding hole 12 slides along the outer end of the guiding rod 13. At this time, the elastic sheet 7 is gradually compressed, and two adjacent cooperating clamping blocks 4 are gradually tightened, and finally the wire is clamped between the two clamping blocks 4 and the arc-shaped seat 3;

[0030] When it is necessary to repair or replace the wire: Rotate the clamping bolt 10 in the reverse direction. The screw sleeve 11 makes the movable seat 2 gradually move away from the fixed seat 1 through the spiral with the clamping bolt 10. The extrusion block 9 gradually disengages from the extrusion of the pressure receiving plate 8. At this time, the two cooperating clamping blocks 4 release the clamping of the wire under the action of the elastic sheet 7. However, after the corresponding two clamping blocks 4 are completely opened, since the gap is smaller than the diameter of the wire, the wire will not fall off automatically and needs to be pulled out manually to be removed, ensuring that the wires that are not repaired and replaced are always in a constrained state.

[0031] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
