Description

Technical Field

[0001] The present invention relates to the technical field of electronic device structures, and particularly to a plug board that can be freely arranged and a usage method thereof. Background Art

[0002] In the field of cabinet electrical integration technology, existing socket board devices generally adopt an integrated fixed structure. Traditional socket boards integrate multiple socket units on a single substrate to form an inseparable overall structure. When a certain socket unit needs to be replaced due to usage wear, electrical faults, or specification upgrades, due to the lack of modular redundancy design, the entire socket board must be replaced as a whole, resulting in low material utilization rate and a significant increase in the cost for end-users. During long-term use, for the maintenance of the socket board, the densely arranged socket units make it necessary to disassemble the entire panel for fault troubleshooting. Although existing improvement schemes have tried to improve performance by increasing the number of sockets or improving the panel material, they have not addressed the fundamental design flaws.

[0003] In view of this, overcoming the defects of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0050] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] Embodiment 1:

[0052] Embodiment 1 of the present invention provides a plug board that can be freely arranged. As shown in Figure 1 and Figure 2 , it includes: a plurality of modular socket boards 1, an upper pressing plate 2, and a lower pressing plate 3. The upper pressing plate 2 and the lower pressing plate 3 are relatively fixed; a first cross beam 20 is provided in the middle of the upper pressing plate 2, and a second cross beam 30 is provided in the middle of the lower pressing plate 3. The first cross beam 20 and the second cross beam 30 divide the upper pressing plate 2 and the lower pressing plate 3 into two skylight areas respectively. The modular socket boards 1 are arranged in the skylight areas, and the first cross beam 20 and the second cross beam 30 are used to clamp and fix the modular socket boards 1.

[0053] As shown in Figure 2 , mounting holes 11 are provided on the modular socket board 1. The mounting holes 11 are used to mount tube sockets, and the tube sockets are fixedly connected to the modular socket board 1 by bolts. In one embodiment, the tube socket can be a connector socket 7 or a fuse socket 8 as shown in Figure 3 . Among them, the shape of the mounting holes 11 can be as shown in Figure 4 , which are three round holes with different diameters, a slot-shaped hole, a double-ear round hole with two arc-shaped grooves symmetrically arranged with the diameter of the round hole as the axis of symmetry, or a triple-ear round hole with three arc-shaped grooves arranged at the same angular interval, so as to adapt to different devices.

[0054] As shown in Figure 5 and Figure 6 , the plug board is installed on a cabinet 6. The lower surface of the lower pressing plate 3 abuts against the surface of the cabinet 6, and the upper pressing plate 2 and the lower pressing plate 3 are fixedly connected to the cabinet 6 by bolts.

[0055] By independently providing a plurality of modular socket boards 1, the positions of the modular socket boards 1 can be freely arranged according to different combination requirements, cable lengths, etc. During subsequent maintenance and repair, only the upper pressing plate 2 needs to be removed, and then the modular socket board 1 that needs to be repaired and replaced can be taken out. It is also possible to change and adjust the position of the modular socket board 1 and the type of devices installed on the modular socket board 1 without disassembling and replacing the entire plug board. Compared with the integrated fixed structure of the socket board in the prior art, the plug board provided by the present invention is more flexible in use and has lower later maintenance costs.

[0056] According to the technical solutions provided above, the structure above will be further elaborated in detail below.

[0057] In the foregoing solution, the first cross beam 20 and the second cross beam 30 are used to clamp and fix the module socket board 1. The specific method may be as follows Figure 7 and Figure 8 As shown, first wing plates 10 are arranged on both sides of the module socket board 1. The thickness of the first wing plates 10 is less than the body thickness of the module socket board 1. The upper pressure plate 2 further includes an upper frame 21. Two ends of the first cross beam 20 are respectively connected to two opposite side edges of the upper frame 21. The lower pressure plate 3 further includes a lower frame 31. The second cross beam 30 is respectively connected to two opposite side edges of the lower frame 31. The upper frame 21 and the lower frame 31 clamp and fix one of the first wing plates 10, and the first cross beam 20 and the second cross beam 30 clamp and fix the other first wing plate 10.

[0058] In an actual application scenario, the required quantity of the module socket boards 1 may be small and cannot fully cover the skylight area. When such a situation occurs, as Figure 9 and Figure 10 shown, the wiring board further includes a support unit 4 and a filling block 5. When the module socket boards 1 are not fully arranged in the skylight area, the filling block 5 is arranged at the vacant position of the skylight area, and the support unit 4 is arranged on at least one filling block 5; the lower end of the support unit 4 passes through the filling block 5 and is in close contact with the lower surfaces of the second cross beam 30 and the filling block 5, and the upper end of the support unit 4 presses the upper surfaces of the first cross beam 20 and the filling block 5, so as to reduce the deformation of the middle parts of the first cross beam 20 and the second cross beam 30.

[0059] Wherein, the support unit 4 is fixedly arranged on at least one filling block 5. According to the force analysis of the first cross beam 20 and the second cross beam 30, since the centers of gravity of the first cross beam 20 and the second cross beam 30 are located in the middle parts, the deformation degree of the middle parts of the first cross beam 20 and the second cross beam 30 is the largest. The filling block 5 can be arranged close to the middle parts of the first cross beam 20 and the second cross beam 30 to disperse the external force applied to the first cross beam 20 and the second cross beam 30 and reduce the deformation of the middle parts of the cross beams. As Figure 11 shown, if only one filling block 5 is arranged on the wiring board, two support units 4 are arranged, and the two support units 4 are arranged on the only filling block 5.

[0060] In an actual application scenario, the arrangement modes of the filling block 5 and the module socket board 1 can be referred to Figure 9 and Figure 11As shown, since the middle parts of the first cross beam 20 and the second cross beam 30 are prone to deformation under external forces, the module socket boards 1 are mostly arranged in the areas near the two ends of the first cross beam 20 and the second cross beam 30, and the filling blocks 5 are arranged in the areas near the middle parts of the first cross beam 20 and the second cross beam 30. Or refer to Figure 12 As shown, in the form where the filling blocks 5 and the module socket boards 1 are arranged alternately, the support units 4 are respectively arranged on two symmetrically arranged filling blocks 5.

[0061] In order to enable the upper pressing plate 2 and the lower pressing plate 3 to fix the filling block 5, as Figure 13 shown, second wing plates 50 are arranged on both sides of the filling block 5. The thickness of the second wing plates 50 is less than the main body thickness of the filling block 5. The upper frame 21 and the lower frame 31 clamp and fix one of the second wing plates 50, and the first cross beam 20 and the second cross beam 30 clamp and fix the other second wing plate 50.

[0062] The above-mentioned first wing plates 10 and second wing plates 50 have the same size. In order to keep the surface of the wiring board flat, the distance from the upper surface of the first wing plate 10 to the module socket board 1 is equal to the thickness of the first cross beam 20, and the distance from the lower surface of the first wing plate 10 to the module socket board 1 is equal to the thickness of the second cross beam 30; the distance from the upper surface of the second wing plate 50 to the module socket board 1 is equal to the thickness of the first cross beam 20, and the distance from the lower surface of the second wing plate 50 to the module socket board 1 is equal to the thickness of the second cross beam 30.

[0063] Taking the connector seat 7 provided on the module socket board 1 as a male head as an example, during the process of plugging and unplugging the female connector, an external force needs to be applied to the module socket board 1 upward or downward. The module socket board 1 conducts the external force to the upper pressing plate 2 and the lower pressing plate 3. If the applied external force is close to the middle parts of the first cross beam 20 and the second cross beam 30, the deformation of the middle parts of the first cross beam 20 and the second cross beam 30 is larger than that of the two ends of the cross beam. Therefore, in order to disperse the influence of the applied external force on the middle part of the cross beam, as Figure 14 and Figure 15 shown, the support unit 4 includes a nut 40 and a hooked screw 41, and the nut 40 and the hooked screw 41 are threadedly connected; two first through holes 51 are provided on the filling block 5, and the two first through holes 51 are arranged on the same side of the filling block 5; the bottom of the nut 40 is in close contact with the upper surfaces of the filling block 5 and the first cross beam 20; the hooked screw 41 passes through the first through hole 51 from bottom to top and is threadedly connected with the nut 40, and the hooked screw 41 abuts against the lower surfaces of the filling block 5 and the second cross beam 30. Among them, since the bottom of the nut 40 is in close contact with the upper surfaces of the filling block 5 and the first cross beam 20, so asFigure 16 As shown, the radius r of the nut 40 is greater than the distance L from the center of the first through hole 51 to the side of the first cross beam 20, so that the nut 40 can abut against the upper surfaces of the filling block 5 and the first cross beam 20.

[0064] In a scenario where multiple connectors are provided, there may be a problem that there are many cables connected to the socket, resulting in messy cables and difficulties for subsequent maintenance. Therefore, as Figure 15 shown, a second through hole 53 is further provided on the filling block 5, and the second through hole 53 can be used to fix a cable organizer for storing cables.

[0065] To ensure that the lower end of the hooked screw 41 can remain in close contact with the lower surfaces of the second cross beam 30 and the module plug board and will not rotate due to factors such as environmental vibration and break away from the contact with the second cross beam 30, continue to refer to Figure 14 and Figure 15 shown, the hooked screw 41 includes a main body portion 410 and a pressing portion 411. A thread is provided at the top of the main body portion 410 for connecting with the nut 40, and the main body portion 410 and the pressing portion 411 are connected at a preset angle; wherein, the preset angle can be 90 degrees. The pressing portion 411 includes a limiting portion 4110 and an abutting portion 4111. An abutting surface 412 is provided above the abutting portion 4111. The abutting portion 4111 is formed by machining the tail of the limiting portion 4110. A first limiting groove 52 is provided on the filling block 5, and the first limiting groove 52 extends from the edge of the module socket board 1 towards the first through hole 51 and is communicated with the first through hole 51. The limiting portion 4110 is coupled with the first limiting groove 52; the abutting surface 412 abuts against the lower surface of the second cross beam 30. In one embodiment, the limiting portion 4110 is cylindrical and the first limiting groove 52 is arc-shaped. In addition, the limiting portion 4110 can also be square, and correspondingly the first limiting groove 52 is also square, as long as its shape can achieve the limitation of the hooked part.

[0066] During the installation process, the hooked screw 41 can be first passed from below the first through hole 51 to above, and the hooked screw 41 is rotated until the limiting portion 4110 is stuck in the first limiting groove 52 and the plane of the abutting portion 4111 abuts against the bottom of the second cross beam 30. Then the nut 40 is screwed tightly with the threaded portion at the top of the hooked screw 41 to fix the hooked screw 41.

[0067] The reason why the support unit 4 can relieve the deformation of the first crossbeam 20 and the second crossbeam 30 is that the hooked part of the hooked screw 41 can tightly hook the bottom surface of the second crossbeam 30, and the upper end of the hooked screw 41 is tightened with a nut 40. In this way, the hooked screw 41 forms a stable support point. This support point not only supports the filling block 5 and the upper pressing plate 2, but also indirectly supports the entire structure through the connection between the upper pressing plate 2 and the lower pressing plate 3. When an external force acts on the connector seat 7 (such as the insertion and extraction force when inserting and extracting the external female head), these external forces will first act on the connector seat 7 and the module socket board 1. Without the hooked screw 41, these external forces will directly be transmitted to the first crossbeam 20 and the second crossbeam 30 through the fixed wings, resulting in a large bending moment in the middle of the first crossbeam 20 and the second crossbeam 30, and thus causing deformation. However, with the hooked screw 41, since the hooked screw 41 is fixed on the filling block 5, the second wing plate 50 on one side of the filling block 5 is clamped and fixed by the upper frame 21 and the lower frame 31, and the lower frame 31 is fixedly installed on the cabinet 6. Then, the hooked screw 41 hooking the second crossbeam 30 and the nut 40 abutting against the first crossbeam 20 and the filling block 5 can share a part of the external force, thereby reducing the force on the middle of the crossbeam. In addition, the hooked screw 41 and its nut 40 are in close contact with the surface of the installation block and the crossbeam surface of the upper cover plate, forming a more stable structural system, which not only improves the overall rigidity of the structure, but also enhances its ability to resist deformation caused by external forces.

[0068] The following analyzes the forces on the hooked screw 41, the first crossbeam 20, and the second crossbeam 30. Taking the case where the external force is applied on one side of the support unit 4 as an example, when there is no hooked screw 41, the bending moment M in the middle of the crossbeam can be calculated from the external force F and the force arm L: M = FL; the deformation δ can be calculated from the bending moment M and the flexural rigidity EI of the beam: where E is the elastic modulus and I is the moment of inertia of the cross-section.

[0069] When there is a hooked screw 41, the hooked screw 41 provides a supporting force. Let the supporting force of the hooked screw 41 be Fs, and the distance from it to the midpoint of the crossbeam be a (a is less than L / 2). The moment M1 generated by the hooked screw 41 is: M1 = Fs·a. Due to the supporting effect of the hooked screw 41, the bending moment in the middle of the crossbeam will decrease, so the bending moment M' in the middle of the crossbeam is M - M1 = FL - Fs·a; the deformation δ' can be calculated from the new bending moment M - M1 and the flexural rigidity EI of the beam: Due to the supporting effect of the hooked screw 41 (i.e., Fs > 0), the new bending moment M' will be less than the original bending moment M. Therefore, the deformation δ' will be less than the original deformation δ.

[0070] In the foregoing solution, the upper pressing plate 2 and the lower pressing plate 3 are relatively fixed. In one embodiment, the specific fixing method may be, for example, Figure 17 As shown, locking latches 22 are provided around the upper pressing plate 2, and locking tongues 32 are provided around the lower pressing plate 3. The locking latches 22 and the locking tongues 32 are correspondingly arranged, and the locking latches 22 and the locking tongues 32 are locked and linked. The locking tongue 32 is fixedly connected to the lower pressing plate 3 by welding or bolt connection.
