DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0029] As shown in Figures 1-6 An electronic engineering junction box, comprising a box body 1, a cover plate 4 movably connected to the top of the box body 1, a handle 5 fixedly installed at the upper end of the cover plate 4, a cover plate dismounting assembly 3 fixedly installed at the top of the left and right sides of the box body 1, and a wiring harness fixing assembly 2 fixedly installed at the front and back of the left and right sides of the box body 1.

[0030] The wiring harness fixing assembly 2 comprises a threading pipe 21, mounting holes provided through the front and back of the left and right sides of the box body 1, the outer wall of the threading pipe 21 fixedly installed with the inner wall of the mounting hole, and four rubber clamp plates 22 movably connected to the inner cavity of the threading pipe 21, wherein the four rubber clamp plates 22 are all arc-shaped structures.

[0031] The cover plate dismounting assembly 3 comprises two fixed plates 31, the upper ends of the two fixed plates 31 fixedly installed with the left and right parts of the lower end of the cover plate 4, a mounting frame 32 fixedly installed at the top of the left and right sides of the box body 1, a clamping plate 33 slidably connected to the inner wall of the two mounting frames 32, the top of the two clamping plates 33 being arc-shaped structures, and a positioning groove 34 provided through the top of the left and right sides of the box body 1 and the opposite side of the two fixed plates 31, and matching the two clamping plates 33.

[0032] The wire harness fixed assembly 2 can fix the wire harness passing through the wire pipe 21, and facilitate workers to connect the wires in the wire harness. The rubber clamping plates 22 and the springs 25 can adapt to and clamp wire harnesses of different sizes, and due to the design of the elastic cloth 26, dust can be prevented from entering the junction box in a large amount, and the utility is strong. The cover plate dismounting assembly 3 can quickly install or dismount the cover plate 4, and facilitate workers to operate in the exposed junction box. When installing, the two moving plates 6 are only needed to be slid into the four guide rails 7. The bottom of the two fixed plates 31 will extrude the arc-shaped structure of the two clamping plates 33, so that the two clamping plates 33 are pushed and slid back into the corresponding mounting frames 32 by the two sliding plates 36, and when the two clamping plates 33 enter the positioning grooves 34 on the two fixed plates 31, the force is lost, and the two fixed plates 31 are reset due to the elastic force of the springs 39, so that the cover plate 4 is quickly fixed. The dismounting of the cover plate 4 only needs the workers to move the two pulling plates 38, and the utility is strong, and manual screwing of screws is not needed.

[0033] As shown in Figure 4 the four rubber clamping plates 22 are fixedly installed on the side away from the axis of the wire pipe 21, the outer sides of the four guide rods 23 penetrate through the outer wall of the wire pipe 21 and are in sliding connection with the outer wall of the wire pipe 21, and the ends away from the axis of the wire pipe 21 of the four guide rods 23 are fixedly installed with the stop blocks 24.

[0034] When the wire harness passes through the four rubber clamping plates 22, the outer wall of the wire harness will push the four rubber clamping plates 22, so that the four rubber clamping plates 22 move through the four guide rods 23, at this time, the movement of the guide rods 23 will extrude the springs 25, and the elastic force of the springs 25 will react on the outer wall of the wire harness, so that the wire harness is fixed in the wire pipe 21. The stop blocks 24 limit the movement of the guide rods 23.

[0035] As shown in Figure 4 the four guide rods 23 are movably sleeved with the springs 25 at positions close to the axis of the wire pipe 21, one end of the four springs 25 close to the axis of the wire pipe 21 is fixedly connected with the side away from the axis of the wire pipe 21 of the four rubber clamping plates 22, and the other end of the four springs 25 away from the axis of the wire pipe 21 is fixedly connected with the inner wall of the wire pipe 21.

[0036] The springs 25 mainly provide clamping force. When the wire harness passes through the wire pipe 21, the rubber clamping plates 22 will move inward due to the extrusion of the wire harness. At this time, the springs 25 will be compressed and generate a reaction force, which is the clamping force. The clamping force can ensure that the rubber clamping plates 22 tightly clamp the wire harness, preventing it from loosening or falling off. Moreover, the elastic force of the springs 25 can make the rubber clamping plates 22 adjust slightly and maintain close contact when being extruded by wire harnesses of different diameters.

[0037] As shown in Figure 3 andFigure 4 As shown, the outer wall of the four rubber splints 22 close to one side of the box body 1 is bonded with elastic cloth 26.

[0038] The elastic cloth 26 has a dustproof effect.

[0039] As shown, Figure 6 The inner walls of the two installation frames 32 are provided with slotted holes 35 at the upper and lower parts. The inner walls of four adjacent slotted holes 35 are slidingly connected with sliding plates 36. The two clamping plates 33 are fixedly connected with the middle parts of the opposite sides of the two sliding plates 36.

[0040] When the worker needs to remove the cover plate 4 to maintain the internal wiring of the box body 1, the two pull plates 38 are moved outwardly of the box body 1, so that the two pull plates 38 drive the sliding plates 36 and the clamping plates 33 to move away from the positioning grooves 34. At this time, the worker pulls the handle 5 upwardly, and the two moving plates 6 at the bottom of the cover plate 4 will slide out from between the two adjacent guide rails 7, so that the cover plate 4 is quickly disassembled.

[0041] As shown, Figure 6 The front and rear parts of the mutually distant sides of the two sliding plates 36 are fixedly installed with adjusting rods 37. The ends of the four adjacent adjusting rods 37 away from each other are fixedly installed with pull plates 38. The outer walls of the four adjusting rods 37 penetrate through the mutually distant sides of the two installation frames 32 and are slidingly connected with the mutually distant sides of the two installation frames 32.

[0042] As shown, Figure 6 The outer walls of the four adjacent adjusting rods 37 close to each other are movably sleeved with springs 39. The opposite ends of the four adjacent springs 39 are fixedly connected with the front and rear parts of the mutually distant sides of the two sliding plates 36. The ends of the four adjacent springs 39 away from each other are fixedly connected with the front and rear parts of the mutually distant sides of the inner walls of the two installation frames 32.

[0043] The spring 39 has a reset function. The presence of the spring 39 not only provides a reset force, but also enhances the stability of the clamping plate 33. In the process of using the junction box, it may be subjected to external vibration or impact. These forces may cause the clamping plate 33 to displace slightly. However, due to the elastic force of the spring 39, it can quickly pull the clamping plate 33 back to the correct position, ensuring the tight connection between the cover plate 4 and the box body 1.

[0044] As shown, Figure 2 and Figure 3 The front and rear parts of the lower end of the cover plate 4 are fixedly installed with moving plates 6. The front and rear positions of the top of the inner wall of the box body 1 are fixedly installed with two guide rails 7. The left and right sides of the two moving plates 6 are slidingly connected with the opposite sides of the four adjacent guide rails 7.

[0045] The cooperation between the moving plate 6 and the adjacent two guide rails 7 improves the stability of the installation of the cover plate 4.

[0046] The working principle of the utility model is: when using, the wire harness is stripped, and the wire harness has multiple wires that need to be connected. Taking one wire harness as an example, the stripped wire harness is inserted through the wire inserting pipe 21, and the outer wall thereof is inserted through the four rubber clamping plates 22, the outer wall of the wire harness pushes the four rubber clamping plates 22, the four rubber clamping plates 22 are moved through the four guide rods 23, the movement of the guide rods 23 extrudes the spring 1 25, and the elastic force of the spring 1 25 acts on the outer wall of the wire harness, so that the wire harness is fixed in the wire inserting pipe 21, and the position of the stripped wire harness is located in the box body 1. In the prior art, the connection between the wires uses a connector (referring to the 221 series connector), and the stripped wires are directly connected through the connector. After the connection is completed, the cover plate 4 is installed, the two moving plates 6 at the bottom of the cover plate 4 are slid into the four guide rails 7, the bottom of the two fixed plates 31 extrudes the arc-shaped structure of the two clamping plates 33, the two clamping plates 33 are pushed and slid into the corresponding installation frame 32 through the two sliding plates 36, when the two clamping plates 33 enter the positioning groove 34 on the two fixed plates 31, the force is lost, and the two fixed plates 31 are fixed due to the elastic force of the spring 2 39, so that the cover plate 4 is quickly fixed. When the worker needs to remove the cover plate 4 to maintain the wire connection in the box body 1, the two pull plates 38 are moved to the outside of the box body 1, so that the two pull plates 38 drive the sliding plates 36 and the clamping plates 33 away from the positioning groove 34, at this time, the worker pulls the handle 5 upwards, the two moving plates 6 at the bottom of the cover plate 4 slide out from between the adjacent two guide rails 7, so that the cover plate 4 is quickly removed.

[0047] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principle of the utility model, and various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model.
