Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically a cable protection device. Background Technology

[0002] The sensor's data acquisition harness uses multiple single-strand wires, each connected to and collecting the voltage or temperature of each electronic component. During cable connection, it's often necessary to link two cables. Currently, a common method is to wrap the cable joint layer by layer with insulating tape until it completely covers the joint. However, because the insulating tape is directly exposed and lacks protection, it is prone to aging or peeling off over time.

[0003] Chinese utility model CN213484502U discloses a cable connector protection device, which incorporates a clamping mechanism to protect the connector. The principle involves passing the cable through the housing, then clamping it inside by pulling on the upper and lower limiting mechanisms. Rotating a knob drives a threaded rod, which in turn moves a slider, causing one clamping plate to move closer to the other, thus securing the cable in place.

[0004] However, existing devices control one clamping plate to move closer to the other during use. Since the other clamping plate is fixed in position, it pushes the cable closer to it during clamping. Because the clamping is not centered, thinner cables may detach from the inside of the clamping mechanism. Therefore, a cable protection device with centered clamping was designed to address the aforementioned problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a cable protection device that has the advantage of being able to clamp the cable in the center, thus keeping the cable in the center position. This solves the problem that existing clamping methods, which are not centered, can cause the cable to shift position and detach from the limiting mechanism.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cable protection device, comprising: a protective shell through which a cable penetrates for protecting the cable connector; a clamping assembly disposed inside the protective shell, the clamping assembly comprising: a threaded protrusion disposed on the outer side wall of the protective shell; a threaded tube sleeved on the outer side wall of the protective shell and threadedly connected to the threaded protrusion; a ring rotatably disposed on one side of the threaded tube; a connecting rod rotatably connected at one end to the ring; an insertion rod inserted at one end into the interior of the protective shell and rotatably connected at the other end to the connecting rod; and a clamping plate disposed at one end of the insertion rod.

[0009] In some embodiments, the clamping plate has an arc-shaped design.

[0010] In some embodiments, the threaded tube further includes: a plurality of rubber protrusions, all disposed on the inner sidewall of the clamping plate.

[0011] In some embodiments, the clamping assembly further includes: anti-slip protrusions disposed on the outer side wall of the threaded tube.

[0012] In some embodiments, the clamping assembly further includes: sealing rings symmetrically disposed on the inner sidewall of the protective housing.

[0013] In some embodiments, the protective shell is provided with a stabilizing component, the stabilizing component comprising: a rectangular shell disposed on the outer side wall of the protective shell; a rectangular block slidably disposed inside the rectangular shell; a threaded rod disposed inside the rectangular block, with one end penetrating through the inner side wall of the rectangular block and the rectangular shell, and threadedly connected to the rectangular block and rotatably connected to the rectangular shell; and a rotating wheel disposed at one end of the threaded rod.

[0014] In some embodiments, the stabilizing components are provided in two sets, both disposed on the outer side wall of the protective shell.

[0015] In some embodiments, the stabilizing component further includes a baffle disposed at the other end of the threaded rod.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a cable protection device with the following advantages:

[0018] 1. This protective device uses the movement of the threaded tube to pull the ring body along with the clamping assembly, which in turn drives the connecting rod to rotate. This causes one end of the connecting rod to push the plug rod into the inside of the protective shell, thereby clamping the cable with the clamping plate and fixing the protective shell at the cable joint to protect the joint.

[0019] 2. This protective assembly, through the rotation of the threaded rod using the stabilizing component, pushes the rectangular block out from inside the rectangular shell and finally abuts against the ring, thus restricting the movement of the ring. This prevents the clamping plate from becoming loose. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0031] The sensor's data acquisition harness uses multiple single-strand wires, each connected to and collecting the voltage or temperature of each electronic component. During cable connection, it's often necessary to link two cables. Currently, a common method is to wrap the cable joint layer by layer with insulating tape until it completely covers the joint. However, because the insulating tape is directly exposed and lacks protection, it is prone to aging or peeling off over time.

[0032] In related technologies, the cable is passed through the housing, and then clamped inside by pulling on the upper and lower limiting mechanisms. A rotating torque drives a threaded rod, which in turn moves a slider, causing one clamping plate to move closer to the other, thus securing the cable. However, existing devices control one clamping plate to move closer to the other. Since the other clamping plate is fixed in position, it pushes the cable closer to it during clamping. Because the clamping is not centered, thinner cables may detach from the clamping mechanism.

[0033] To address some of the problems in related technologies, this application provides a cable protection device. When cable connectors need protection, one end of the cable is first passed through the interior of the protective housing 11 and then connected to another cable connector. After connection, the cable is pulled to insert the connector into the interior of the protective housing 11. Then, the cable needs to be clamped. At this time, the threaded tube 22 can be rotated to connect with the threaded protrusion 21 and move on the outer wall of the protective housing 11. At the same time, the ring 23 on one side is pulled to rotate. Because the ring is rotatably connected to the threaded tube 22, the rotation of the threaded tube 22 will not drive the ring 23 to rotate. When the ring 23 moves, it will pull the connecting rod 24 to rotate, thereby causing one end of the connecting rod 24 to push the insertion rod 25 into the interior of the protective housing 11 and push the clamping plate 26 to fit against the outer wall of the cable, clamping the cable and fixing the connector position inside the protective housing 11 to protect the connector.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figures 1-4 This application provides a cable protection device, including: a protective shell 11 through which a cable passes to protect the cable connector; a clamping assembly 2 is provided inside the protective shell 11, the clamping assembly 2 including: a threaded protrusion 21 fixedly disposed on the outer side wall of the protective shell 11; a threaded tube 22 sleeved on the outer side wall of the protective shell 11 and threadedly connected to the threaded protrusion 21; a ring 23 rotatably disposed on one side of the threaded tube 22; a connecting rod 24 rotatably connected at one end to the ring 23; an insertion rod 25 inserted at one end into the interior of the protective shell 11 and rotatably connected at the other end to the connecting rod 24; and a clamping plate 26 fixedly disposed at one end of the insertion rod 25.

[0036] When it is necessary to protect the cable connector during use, first pass one end of the cable through the inside of the protective shell 11 and connect it to another cable connector. After the connection is completed, pull the cable to pull the connected connector into the inside of the protective shell 11. Then, the cable needs to be clamped. At this time, the threaded tube 22 can be rotated so that the threaded tube 22 connects with the threaded protrusion 21 and moves on the outer wall of the protective shell 11. At the same time, pull the ring 23 on one side to rotate. Because the ring is rotatably connected to the threaded tube 22, the rotation of the threaded tube 22 will not drive the ring 23 to rotate. When the ring 23 moves, it will pull the connecting rod 24 to rotate, so that one end of the connecting rod 24 pushes the insertion rod 25 into the inside of the protective shell 11 and pushes the clamping plate 26 to fit against the outer wall of the cable, clamping the cable and fixing the connector position inside the protective shell 11 to protect the connector.

[0037] In some embodiments, the clamping plate 26 is arc-shaped.

[0038] When in use, the inner arc design of the clamp 26 allows it to better fit the surface of the cable, thereby increasing the contact area with the cable and enhancing the clamping effect.

[0039] In some embodiments, the threaded tube 22 further includes: multiple rubber protrusions 27, all disposed on the inner sidewall of the clamping plate 26.

[0040] When in use, the design of the rubber protrusion 27 can protect the surface of the cable while increasing friction, making it more secure when clamped.

[0041] In some embodiments, the clamping assembly 2 further includes an anti-slip ridge 28 disposed on the outer side wall of the threaded tube 22.

[0042] The anti-slip ridge 28 is designed to increase friction when rotating the threaded tube 22, making it easier to apply force when gripping and rotating.

[0043] In some embodiments, the clamping assembly 2 further includes a sealing ring 29 symmetrically disposed on the inner sidewall of the protective shell 11.

[0044] When in use, the sealing ring 29 is made of soft rubber. Inside the cable, the sealing ring can better fit the surface of the cable, thereby reducing gaps and preventing some impurities and dust from entering.

[0045] In some embodiments, a stabilizing component 3 is provided on the protective shell 11. The stabilizing component 3 includes: a rectangular shell 31 disposed on the outer side wall of the protective shell 11; a rectangular block 32 slidably disposed inside the rectangular shell 31; a threaded rod 33 disposed inside the rectangular block 32, with one end penetrating through the inner side wall of the rectangular block 32 and the rectangular shell 31, and threadedly connected to the rectangular block 32 and rotatably connected to the rectangular shell 31; and a rotating wheel 34 disposed at one end of the threaded rod 33.

[0046] In order to ensure that the clamping does not loosen after clamping and fixing, the rotating wheel 34 can be rotated. When the rotating wheel 34 rotates, it will drive the threaded rod 33 to rotate together. At this time, because the rectangular shell 31 can restrict the rectangular block 32 and restrict the rotation of the rectangular block 32, when the threaded rod 33 rotates, it will drive the rectangular block 32 to extend out from the inside of the rectangular shell 31 until it contacts the ring 23 and can hold the ring 23, thereby stabilizing the position of the ring 23 and preventing the clamping plate 26 from loosening.

[0047] In some embodiments, the stabilizing components 3 are provided in two sets, both of which are disposed on the outer side wall of the protective shell 11.

[0048] The design of two sets of stabilizing components 3 during use can make the limiting effect better.

[0049] In some embodiments, the stabilizing component 3 further includes a baffle 35 disposed at the other end of the threaded rod 33.

[0050] The design of the baffle 35 during use can prevent the threaded rod 33 from detaching from the rectangular block 32 during rotation.
