Description

Technical Field

[0001] The invention relates to the technical field of vehicle jumper wires, and in particular to a universal jumper wire clamping plate module. Background Art

[0002] In recent years, low-floor trams have developed rapidly in my country as a new form of urban rail transit. To facilitate passengers to enter the car, the biggest feature of low-floor trams is the low floor surface of the passenger compartment. The low floor surface has resulted in many large electrical equipment being moved from the traditional undercarriage to the roof where the space is relatively limited. At the same time, the operating characteristics of trams determine that the electrical connections and gas-liquid connections between carriages should have the functions of easy maintenance and quick disassembly. However, the existing wire clamp structure is complex. When only a single or a few cables need to be adjusted and disassembled, the wire clamp structure needs to be disassembled as a whole, which is inconvenient to use. Summary of the invention

[0003] The present invention aims to provide a universal jumper clamping plate module, which is more convenient to disassemble when the cables need to be adjusted.

[0004] The embodiment of the present invention is achieved as follows:

[0005] A universal jumper clamping plate module, comprising:

[0006] The wire clamp structure is mainly composed of at least three clamping plates connected in parallel in a transverse direction; and,

[0007] A locking structure, used to limit the relative displacement between the clamps in the lateral direction, and the locking structure can release the restriction on the clamps;

[0008] The side of the clamping plate connected to another clamping plate is concavely formed with a plurality of half-hole structures, and the half-hole structures on the two connected clamping plates are correspondingly assembled to form a plurality of wire holes for the cables to pass through.

[0009] Preferably, a support structure is further included, wherein the support structure includes a connecting portion connected to the vehicle crossing bridge, and the wire clamp structure is fixedly connected to the connecting portion.

[0010] Preferably, the support structure further comprises a supporting portion for supporting the wire clamp structure, and the supporting portion is connected to the connecting portion to transfer the load of the wire clamp structure to the vehicle wire bridge.

[0011] Preferably, the connecting portion is U-shaped, and the vehicle crossing bridge is clamped in the U-shaped opening of the connecting portion.

[0012] Preferably, the number of components of the wire clamp structure is two groups, and they are arranged at intervals in the lateral direction. The bracket structure is arranged between the two groups of wire clamp structures. Two groups of supporting parts are formed on the bracket structure and are respectively connected to the wire clamp structures on both sides. The two groups of supporting parts are respectively connected to the two side edges of the U-shaped opening of the connecting part. The innermost clamping plates of the two groups of wire clamp structures are abutted against the two side edges of the U-shaped opening of the connecting part.

[0013] Preferably, the locking structure is mainly composed of a locking bolt whose threaded section sequentially penetrates each clamping plate and the side of the connecting part in the transverse direction and extends into the U-shaped opening, and a stop nut threadedly connected to the portion where the locking bolt extends into the U-shaped opening, and the head of the locking bolt and the stop nut clamp the clamping plate therebetween.

[0014] Preferably, a clamping strip is provided between the head of the locking bolt and the clamping plate.

[0015] Preferably, it further comprises an elastic ring coaxially interference-fitted in the wire hole, wherein the inner periphery of the elastic ring is interference-fitted with the outer periphery of the cable passing through the wire hole.

The semi-hole structures on the connected clamps enclose a wire hole for the cable to pass through, and the clamps are locked by a locking structure. When faced with a situation where the cable needs to be adjusted, the implementer releases the locking structure on each clamp, and separates the clamps on both sides of the cable that needs to be adjusted from each other in the horizontal direction, so that the cable can be detached from the wire hole; during the detachment process of the cable that needs to be adjusted, the remaining cables can still be retained in the wire hole and will not be completely separated from the wire clamp structure, eliminating the need to assemble these cables again during the assembly process, thereby improving the convenience of loading and unloading the universal jumper clamp module.

[0033] Example 1

[0034] See also Figures 1 to 3 The present embodiment 1 provides a universal jumper clamping plate module 60, comprising:

[0035] The wire clamp structure is mainly composed of at least three clamping plates 11 which are connected in parallel in the transverse direction; and,

[0036] A locking structure, used to limit the relative displacement between the clamps 11 in the lateral direction, and the locking structure can release the restriction on the clamps 11;

[0037] The side of the clamping plate 11 connected to another clamping plate 11 is concavely formed with a plurality of half-hole structures, and the half-hole structures on the two connected clamping plates 11 are correspondingly assembled to form a plurality of wire holes for the cables to pass through.

[0038] When a single cable or a small number of cables need to be adjusted or replaced, the implementer releases the locking structure for each clamping plate 11, and separates the clamping plates 11 on both sides of the cable that needs to be adjusted from each other in the horizontal direction, so that the cable can be detached from the wire hole. During the detachment of the cable that needs to be adjusted, the remaining cables can still be retained in the wire hole and will not be completely separated from the wire clamping structure, thus eliminating the need to assemble these cables again during the assembly process, thereby improving the convenience of loading and unloading the universal jumper clamping plate module 60.

[0039] In order to ensure that the above-mentioned wire clamp structure can be fixed relative to the vehicle body and in a fixed position during its use, as a preferred embodiment, in this embodiment 1, a bracket structure is also included, and the bracket structure includes a connecting portion 31 connected to the vehicle wire bridge 50, and the wire clamp structure is fixedly connected to the connecting portion 31. Among them, the connecting portion 31 is used to connect with the vehicle wire bridge 50 to ensure that the entire universal jumper clamp plate module 60 can be roughly in a fixed position when in use.

[0040] At the same time, since the wire clamp structure will bear part of the load of the cable during use, in order to ensure that the load borne by the wire clamp structure can be stably transmitted to the vehicle overpass bridge 50, it is avoided that the wire clamp structure and the connecting part 31 only rely on the fixed connection between the two to transmit the above load to the vehicle overpass bridge 50. Figure 4 In this embodiment 1, the support structure also includes a supporting portion 32 for supporting the wire clamp structure, and the supporting portion 32 is connected to the connecting portion 31 to transfer the load of the wire clamp structure to the vehicle overpass 50, which is particularly suitable for the case where the wire clamp structure is arranged on the lateral side of the connecting portion 31.

[0041] Regarding the above-mentioned connecting portion 31, in the present embodiment 1, it is specifically in a U-shape, and its U-shaped opening constitutes a bayonet adapted to the vehicle crossing bridge 50. The implementer may also replace the above-mentioned structure by providing a connecting portion of a clamping mechanism.

[0042] In order to improve the accommodating capacity of the entire universal jumper clamp plate module 60, in the present embodiment 1, the number of components of the wire clamp structure is two groups, and they are arranged in a lateral interval. The bracket structure is arranged between the two groups of wire clamp structures. Two groups of supporting parts 32 are formed on the bracket structure and are respectively connected to the wire clamp structures on both sides. The two groups of supporting parts 32 are respectively connected to the two side edges of the U-shaped opening of the connecting part 31. The innermost clamp plates 11 of the two groups of wire clamp structures are against the two side edges of the U-shaped opening of the connecting part 31.

[0043] The structural form in which the above-mentioned two groups of supporting parts 32 are placed on the horizontal sides of the same bracket structure can make the overall center of gravity of the entire universal jumper wire clamp module 60 roughly approach the position between the two wire clamp structures, so as to optimize the weight distribution, so that the weight of the universal jumper wire clamp module 60 can be more stably transferred to the wire bridge 50, avoiding the accident of the entire module tipping over when multiple wire clamp structures are set.

[0044] More specifically, in this embodiment 1, the splint 11 is made of PA66 material, which can also be replaced by other materials. The specific number of splints 11 in each set of wire clamp structures is 3 pieces, and the two sets of wire clamp structures provide a total of 21 sets of wire holes, including 3 groups of φ34 corrugated hoses, 4 groups of φ25 metal hoses, 2 groups of water-cooling liquid pipelines, and 10 groups of cables, so that the universal jumper wire splint module 60 of this embodiment 1 can realize various forms of jumpering, including but not limited to electrical, gas, and liquid jumpering.

[0045] Regarding the above-mentioned locking structure, in the present embodiment 1, in addition to realizing the locking function, it is also used to connect the wire clamp structure and the connecting portion 31 .

[0046] Specifically, the locking structure is mainly composed of a locking bolt 21 whose threaded section sequentially penetrates each clamp plate 11 and the side of the connecting portion 31 in the transverse direction and extends into the U-shaped opening, and a stop nut 22 threadedly connected to the portion where the locking bolt 21 extends into the U-shaped opening. The head of the locking bolt 21 and the stop nut 22 clamp the clamp plate 11 therebetween.

[0047] Please see again Figure 1 , the stop nut 22 is screwed out relative to the locking bolt 21, and the clamping plate 11 between the two can be loosened, and the implementer can separate each clamping plate 11 in the horizontal direction to remove the cable. In the assembly process, the implementer splices each clamping plate 11 side by side in the horizontal direction, and tightens the stop nut 22 to lock each clamping plate 11 in the horizontal direction. This structure ensures the assembly action of the clamping plate 11 in the wire clamp structure, and the combination of the assembly action of the connecting part 31 and the wire clamp structure, which is convenient for users.

[0048] In addition, since the load borne by the wire clamp structure and the load it carries are mainly transmitted to the connecting part 31 by the supporting part 32, the locking bolt 21 mainly plays a tightening role and is not subjected to shear force as a whole. This arrangement extends the service life of the locking structure.

[0049] As a preferred embodiment, in this embodiment 1, a clamping strip 41 is provided between the head of the locking bolt 21 and the clamping plate 11, which plays a role in dispersing the tightening force of the locking bolt 21 and ensuring the reliability of the entire device. At the same time, the above-mentioned supporting portion 32 is specifically integrally formed with the connecting portion 31, and the connecting portion 31, the supporting portion 32 and the clamping strip 41 are all made of t4 stainless steel 304.

[0050] More specifically, regarding the relationship between the wire hole and the cable, in the present embodiment 1, an elastic ring 12 is coaxially interference fit in the wire hole, and the inner periphery of the elastic ring 12 is interference fit with the outer periphery of the cable passing through the wire hole. The elastic ring 12 is fixed relative to the wire hole and the cable by means of the interference fit, ensuring that there is no relative movement between the entire universal jumper clamp module 60 and the cable.

[0051] In addition, in the present embodiment 1, a flange coaxial with the inner hole is formed on the outer periphery of the elastic ring 12, and an annular assembly groove for the flange to be inserted is formed on the inner periphery of the wire hole to avoid the accident that the elastic ring 12 is pulled out of the wire hole due to force.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
