Description

Technical Field

[0001] This utility model relates to the field of cable assembly technology, and in particular to a shielded rigid cable assembly. Background Technology

[0002] The emergence of rigid shielded cables stems from the need for electromagnetic interference protection and improved cable mechanical performance. In industries and communications, electromagnetic interference can affect signal transmission and normal equipment operation, thus requiring cables to have shielding capabilities to resist external interference and reduce their own radiation. Simultaneously, in complex or harsh environments, cables must withstand mechanical pressure and tension; rigid structures provide better support and protection. With technological advancements, the requirements for cable transmission performance, anti-interference capabilities, and mechanical strength are constantly increasing, prompting continuous improvements in rigid shielded cable technology to adapt to diverse application scenarios.

[0003] Currently, the conventional procedure for wiring shielded rigid cables is as follows: first, use specialized tools to cut open the outer sheath of the cable; then, carefully peel off the inner shielding layer and pull it out separately, connecting it properly to the ground wire; while the core of the cable is connected to the circuit in the usual way. However, this traditional wiring method has obvious drawbacks. The operation steps are cumbersome and complex, requiring a lot of time and effort, and is prone to wiring errors due to improper operation, thus affecting the wiring quality and efficiency. Based on this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a shielded rigid cable assembly that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shielded rigid cable assembly includes an inner core for conducting electricity, and further includes: a shielding layer sleeved on the inner core, and a sheath sleeved on the shielding layer; a sliding sleeve slidably connected to the shielding layer, a cutting block connected to the sliding sleeve, a terminal fixedly connected to the sliding sleeve, and a second threaded buckle fixedly connected to the sliding sleeve; when the sliding sleeve slides on the shielding layer, the cutting block cuts open the sheath; when the sliding sleeve slides on the shielding layer, the shielding layer at the clamping end of the second threaded buckle moves synchronously, and the wound shielding layer is collected inside the sliding sleeve.

[0007] Preferably, an adjusting threaded cylinder is fixedly connected to the sliding sleeve, and the cutting block is slidably connected to the adjusting threaded cylinder.

[0008] Preferably, the adjusting threaded cylinder is connected to a compression threaded cylinder by a thread, and when the compression threaded cylinder moves laterally, the cutting blocks on both sides are squeezed together towards the middle.

[0009] Preferably, a second threaded buckle is fixedly connected to the sliding sleeve, and a second locking threaded sleeve is threadedly connected to the second threaded buckle.

[0010] Preferably, a positioning sleeve is slidably connected to the sheath, and a first threaded buckle is fixedly connected to the positioning sleeve. A first locking threaded sleeve is threadedly connected to the first threaded buckle.

[0011] Furthermore, the positioning sleeve is provided with a sliding groove, and a connecting threaded cylinder is rotatably connected to the sliding groove. The other end of the connecting threaded cylinder is connected to the sliding sleeve by a thread.

[0012] Furthermore, the sliding sleeve and the second threaded buckle are made of conductive metal, while the connecting threaded sleeve is made of insulating material.

[0013] Preferably, the terminal block is threadedly connected to a clamping bolt, and a metal washer is connected to the clamping bolt.

[0014] Compared with the prior art, the present invention provides a shielded rigid cable assembly, which has the following advantages:

[0015] 1. This shielded rigid cable assembly, by setting a sliding sleeve and a cutting block, allows the sliding sleeve to open and cut the sheath during the sliding process, thus saving the user the step of cutting the sheath.

[0016] 2. This shielded rigid cable assembly moves the end of the shielding layer together with the second threaded buckle through the sliding sleeve. The shielding layer is squeezed and contracted in the space inside the sliding sleeve, thereby completing the consolidation of the shielding layer. The shielding layer is connected to the grounding wire by setting the wiring terminal.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example 1: Refer to Figures 1-6A shielded rigid cable assembly includes an inner core 12 for conducting electricity, and further includes: a shielding layer 11 sleeved on the inner core 12, and a sheath 1 sleeved on the shielding layer 11; a sliding sleeve 3 slidably connected to the shielding layer 11, a cutting block 33 connected to the sliding sleeve 3, a terminal block 34 fixedly connected to the sliding sleeve 3, and a second threaded buckle 36 fixedly connected to the sliding sleeve 3; when the sliding sleeve 3 slides on the shielding layer 11, the cutting block 33 cuts the sheath 1; when the sliding sleeve 3 slides on the shielding layer 11, the second threaded buckle 36 clamps the end of the shielding layer 11 and moves synchronously, and the wound shielding layer 11 is collected inside the sliding sleeve 3.

[0028] This utility model applies to cables where the shielding layer 11 is a mesh structure woven from metal wires. The cable consists of three layers: the outermost layer is a rubber sheath 1; inside the sheath 1 is the shielding layer 11 woven from conductive metal wires; and inside the shielding layer 11 is an inner core 12 composed of multiple copper wires with rubber sheaths. At the factory, a section of the sheath 1 at both ends is cut off, and a sliding sleeve 3 is fitted and secured to the shielding layer 11 by the second threaded buckle 36. When the user needs to use the cable, the sliding sleeve 3 is slid, and the cutting block 33 on the sliding sleeve 3 moves along the shielding layer... The gap between the shielding layer 11 and the inner core 12 allows the shielding layer 1 to be opened and cut, thus eliminating the need for the user to cut the shielding layer 1. As the sliding sleeve 3 moves, the second threaded buckle 36 moves the end of the shielding layer 11 together. The shielding layer 11 is squeezed and contracted in the space inside the sliding sleeve 3. When the sliding sleeve 3 moves to the required position, the ground wire is connected to the terminal 34 through the external wire to complete the wiring of the shielding layer 11. There is no need to spend time separating the shielding layer 11 from the inner core 12, nor is it necessary to connect the shielding layer 11 to the ground wire. The operation is simple and convenient.

[0029] Example 2: Refer to Figures 1-6Similar to Embodiment 1, but with a further improvement: an adjusting threaded cylinder 31 is fixedly connected to the sliding sleeve 3, and the cutting block 33 is slidably connected to the adjusting threaded cylinder 31. A pressing threaded cylinder 32 is threadedly connected to the adjusting threaded cylinder 31. When the pressing threaded cylinder 32 moves laterally, the cutting blocks 33 on both sides are pressed together towards the center. A second threaded buckle 36 is fixedly connected to the sliding sleeve 3, and a second locking threaded cylinder 37 is threadedly connected to the second threaded buckle 36. A positioning sleeve 2 is slidably connected to the sheath 1. A first threaded buckle 21 is fixedly connected to the sleeve 2. A first locking threaded cylinder 22 is threadedly connected to the first threaded buckle 21. A sliding groove 23 is provided on the positioning sleeve 2. A connecting threaded cylinder 4 is rotatably connected to the sliding groove 23. The other end of the connecting threaded cylinder 4 is threadedly connected to the sliding sleeve 3. The sliding sleeve 3 and the second threaded buckle 36 are made of conductive metal, while the connecting threaded cylinder 4 is made of insulating material. A clamping bolt 35 is threadedly connected to the terminal 34. A metal washer 351 is connected to the clamping bolt 35.

[0030] In this invention, the end of the extrusion threaded cylinder 32 is flush with the inclined surface of the cutting block 33. When the extrusion threaded cylinder 32 is rotated and moved laterally, the extrusion threaded cylinder 32 will press the cutting block 33 towards the middle position, thereby adjusting the tightness of the contact between the cutting block 33 and the shielding layer 11, ensuring that the cutting block 33 can separate and cut the sheath 1 while sliding on the shielding layer 11;

[0031] Both the first locking threaded cylinder 22 and the second locking threaded cylinder 37 have beveled ends for pressing the first threaded buckle 21 and the second threaded buckle 36 when moving laterally, moving them towards the center for clamping. This allows the user to adjust the clamping force of the first threaded buckle 21 and the second threaded buckle 36 by rotating the first locking threaded cylinder 22 and the second locking threaded cylinder 37.

[0032] The connecting threaded sleeve 4 is rotatably connected to the positioning sleeve 2. When the sliding sleeve 3 moves to one side of the positioning sleeve 2, the sliding sleeve 3 is connected to the positioning sleeve 2 through the thread, thereby completing the fixation of the sliding sleeve 3.

[0033] The connecting threaded sleeve 4 is made of insulating material, thereby preventing current from being conducted to the positioning sleeve 2 through the connecting threaded sleeve 4;

[0034] Users can wrap the external wires around the clamping bolt 35, and by rotating the clamping bolt 35, the metal washer 351 is moved down to clamp and fix the wires.

[0035] When using the device, the user first slides and adjusts the positioning sleeve 2 to move it to the distance required to expose the inner core 12. Then, by rotating the first locking threaded sleeve 22, the positioning sleeve 2 is fixed to the sheath 1. Subsequently, by rotating the second locking threaded sleeve 37 and the adjusting threaded sleeve 31, the position of the second threaded buckle 36 and the cutting block 33 is adjusted. The sliding sleeve 3 can then be moved to the positioning sleeve 2. Since the shielding layer 11 generally has a certain deformation capability and is not fixedly connected to the inner core 12, the second threaded buckle 36 will drive the end of the shielding layer 11 to move together. After the user tears the sheath 1 into two halves, the user rotates the connecting threaded sleeve 4 to connect the sliding sleeve 3 and the positioning sleeve 2 together, and rotates the second threaded buckle 36 to make the second locking threaded sleeve 37 tightly connected to the shielding layer 11. Finally, the external wire is connected to the terminal 34 and the grounding wire to complete the connection between the shielding layer 11 and the grounding wire, and sufficient length of the inner core 12 is left for wiring.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
