Description

Technical Field

[0001] This utility model relates to the field of anti-interference cable technology, and specifically to an anti-interference cable. Background Technology

[0002] Anti-interference cable is a multi-core flexible conductor with a soft conductor, PVC insulation, an outer shielding layer, and a PVC sheath.

[0003] Traditional anti-interference cables consist of internal conductors and a protective sheath surrounding the internal conductors, as well as a shielding layer filled between the internal conductors and the outer protective sheath. The shielding layer is made of metal foil, copper mesh, or aluminum foil and can effectively shield external electromagnetic radiation and interference signals inside the cable, preventing them from interfering with the signal.

[0004] Traditional anti-interference cables require the use of other fixing components, such as fasteners, during installation to ensure stability and prevent shaking and wear. However, these fasteners are typically used to lock the anti-interference cable directly to the wall or floor. Once the locking point is determined, it is difficult to change, making them inflexible and unsuitable for installation on boards, countertops, or columns. This results in strict installation requirements and inconvenience. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an anti-interference cable that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an anti-interference cable, including a cable body and a base. The top of the base has an assembly cavity for placing the cable body. A transmission seat is fixedly installed at the top of the base. An arc-shaped extrusion plate is slidably installed in the assembly cavity and presses against the outer surface of the cable body. An L-shaped top seat is fixedly installed at the top of the transmission seat. An extrusion plate that can slide up and down and moves synchronously but in the opposite direction to the arc-shaped extrusion plate is elastically installed between the L-shaped top seat and the transmission seat.

[0008] Furthermore, the cable body includes a core wire, a shielding layer, and an outer sheath, with the shielding layer covering the surface of the core wire and the outer sheath covering the surface of the shielding layer.

[0009] Furthermore, a transmission gear is rotatably mounted inside the transmission seat, and two L-shaped racks, a first L-shaped rack and a second L-shaped rack, are meshed on the outer ring wall of the transmission gear and are centrally symmetrically distributed about the transmission gear. The second L-shaped rack is fixedly connected to the bottom of the extrusion plate.

[0010] Furthermore, a first spring is installed between the top end of the arc-shaped extrusion plate and the bottom of the transmission seat. The first spring contains a shaft cylinder and a shaft rod that are interlocked with each other. The bottom of the shaft cylinder is installed on the top end of the arc-shaped extrusion plate. The top end of the shaft rod extends into the transmission seat and is fixedly connected to the end of the first L-shaped rack. The outer wall of the shaft cylinder has several air inlet and outlet holes that penetrate the inner cylinder cavity.

[0011] Furthermore, the L-shaped top seat has sliding holes through both sides, and the L-shaped top seat has two sliding grooves symmetrically distributed about the sliding hole axis on the side near the extrusion plate. The extrusion plate has a sliding through-hole installed on one side, which extends to the outside of the L-shaped top seat. It also has sliders that are slidably installed in the corresponding sliding grooves.

[0012] Furthermore, four second springs are installed between the bottom of the extrusion plate and the top of the transmission seat, and arc-shaped rubber sheets are installed at the top of the extrusion plate and the top of the inner wall of the L-shaped top seat.

[0013] The technical solution provided by this utility model, compared with the known prior art, has the following advantages:

[0014] Beneficial effects:

[0015] 1. It is equipped with a base for easy placement of anti-interference cables of different models and specifications. The base is equipped with an arc-shaped extrusion plate that can compress the anti-interference cable. At the same time, an L-shaped top seat is set on the top of the base, and an extrusion plate that can be raised and lowered and slid is set in the L-shaped top seat. Through the elastic expansion and contraction of the extrusion plate, together with the L-shaped top seat, the L-shaped top seat (base) and the anti-interference cable can be locked and fixed in various installation scenarios such as board surface, table surface and column. When it is necessary to change the locking position of the anti-interference cable, the base and the L-shaped top seat can be slid directly on the anti-interference cable, which has the characteristics of flexible and convenient use.

[0016] 2. The locking and fixing of anti-interference cables of different models and specifications by the arc-shaped extrusion plate, as well as the extrusion plate's pressing and fixing of different plate surfaces and columns, are carried out synchronously through the transmission structure between the base and the L-shaped top seat. This reduces the number of operation steps and improves the installation efficiency of anti-interference cables. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example 1

[0031] Reference Figure 1-4This first embodiment of the present invention discloses an anti-interference cable, including a cable body 1 and a base 2. The top of the base 2 has an assembly cavity 21 for placing the cable body 1. A transmission seat 3 is fixedly installed on the top of the base 2. An arc-shaped extrusion plate 4 is slidably installed in the assembly cavity 21 and presses against the outer surface of the cable body 1. The bottom of the arc-shaped extrusion plate 4 is designed with an arc surface to facilitate full pressing against anti-interference cables of different outer diameters. An L-shaped top seat 5 is fixedly installed on the top of the transmission seat 3. An extrusion plate 53, which can slide up and down and moves synchronously but in the opposite direction to the arc-shaped extrusion plate 4, is elastically installed between the L-shaped top seat 5 and the transmission seat 3. This reduces the number of operation steps and improves the installation efficiency of anti-interference cables of different outer diameters.

[0032] Example 2

[0033] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that: the cable body 1 includes a core wire, a shielding layer, and an outer sheath. The shielding layer wraps around the surface of the core wire, and the outer sheath wraps around the surface of the shielding layer. A transmission gear 31 is rotatably installed inside the transmission seat 3. Two L-shaped racks 32 and 33, which are centrally symmetrically distributed about the transmission gear 31, are meshed on the outer ring wall of the transmission gear 31. The second L-shaped rack 33 is fixedly connected to the bottom of the extrusion plate 53. A first spring 41 is installed between the top of the arc-shaped extrusion plate 4 and the bottom of the transmission seat 3. The first spring 41 has a shaft cylinder 42 and a shaft rod 43 that are interlocked inside, which can improve the stability of the extension and contraction of the first spring 41, ensure that the first spring 41 will not deviate or bend, and limit the maximum extension and contraction of the first spring 41 to avoid the first spring 41 compressing or extending beyond its own bearing limit and causing irreversible damage. The bottom of the shaft cylinder 42 is installed on the arc-shaped extrusion plate. At the top of the shaft 43, the top of the shaft 43 extends into the transmission seat 3 and is fixedly connected to the end of the first L-shaped rack 32. The outer wall of the shaft cylinder 42 is provided with several air inlet and outlet holes 44 through the inner cylinder cavity to facilitate the extension and retraction of the shaft 43 within the shaft cylinder 42. The L-shaped top seat 5 is provided with sliding holes 51 through both sides. The L-shaped top seat 5 is provided with two sliding grooves 52 symmetrically distributed about the sliding holes 51 on the side near the extrusion plate 53. The extrusion plate 53 is provided with a sliding through hole 51 on one side and a lifting block 54 extending to the outside of the L-shaped top seat 5 to facilitate the extension and retraction of the extrusion plate 53. Sliding blocks 55 are also provided and slidably installed in the corresponding sliding grooves 52 to improve the extension and retraction stability of the extrusion plate 53. Four second springs 56 are installed between the bottom of the extrusion plate 53 and the top of the transmission seat 3. The top of the extrusion plate 53 and the top of the inner wall of the L-shaped top seat 5 are provided with arc-shaped rubber sheets 57, which can fully fit with the surface of the plate, table or column that is arc-shaped, thus improving the stability of the extrusion fixation.

[0034] The remaining structure is the same as that in Example 1.

[0035] The workflow of this utility model is as follows:

[0036] First, the lifting block 54 is pushed towards the transmission seat 3, thereby forcing the extrusion plate 53 to approach the transmission seat 3. Several second springs 56 between the extrusion plate 53 and the transmission seat 3 are forced to compress. During the movement of the extrusion plate 53, the transmission gear 31 is rotated by the meshing of the second L-shaped rack 33, which in turn meshes with and drives the first L-shaped rack 32, that is, the arc-shaped extrusion piece 4 to move towards the transmission seat 3 by the first spring 41. At this time, the cavity opening of the assembly cavity 21 is exposed, and the cable body 1 is placed in the assembly cavity 21 of the base 2.

[0037] Next, along the surface of the cable body 1, move the base 2 and the L-shaped top seat 5 to the designated installation position, and insert the space between the extrusion plate 53 and the top of the inner wall of the L-shaped top seat 5 into the plate, table, or column to be installed. Then release the lifting block 54. At this time, several second springs 56 elastically return and push the extrusion plate 53 away from the transmission seat 3 and press against the plate, table, or column, completing the limiting and fixing of the L-shaped top seat 5. With the movement of the extrusion plate 53, the transmission gear 31 is driven to rotate through the meshing of the second L-shaped rack 33, which in turn meshes with and drives the first L-shaped rack 32, that is, the arc-shaped extrusion piece 4 to move away from the transmission seat 3 through the first spring 41. Finally, the arc-shaped extrusion piece 4 presses against the surface of the cable body 1, completing the locking and fixing between the arc-shaped extrusion piece 4 and the cable body 1 and the base 2, thus finally completing the installation of anti-interference cables of different outer diameter specifications.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
