Description

Technical Field

[0001] The invention relates to the technical field of electrical material protection, in particular to a water-proof cable protective cover. Background Art

[0002] Cables are electrical materials used to transmit and distribute electrical energy or signals. Cables are widely used in power systems, communication systems, transportation, household appliances and many other fields.

[0003] At present, cables, as a kind of high-value electrical materials, are often stored in outdoor environments. Due to the diversity of usage requirements, cables sometimes need to be cut during use to adapt to specific installation lengths or configuration requirements. In outdoor environments, cables are easily affected by natural factors such as wind, sun, and rain, which may have an adverse effect on the performance and life of the cables. For example, when the cable is cut, the break will face upward. In this case, if it rains, moisture may penetrate into the cable along the cut edge. After the cable is flooded, it will not only affect its performance in transmitting electrical energy or signals, but may also damage the insulation layer of the cable, thereby shortening the service life of the cable, and may even cause cable failure, posing a threat to the stable operation of the entire power or communication system. In the prior art, operators generally use insulating tape to wrap the cut end of the cable to protect it.

[0004] During implementation, the inventors found that the above-mentioned prior art has at least the following defects: when wrapping the cut end of the cable with insulating tape, the operation process is relatively cumbersome and the protection effect on the cable end is poor. Summary of the invention

[0005] The embodiment of the present application provides a water-proof cable protective cover to solve the technical problems in the prior art of complicated operation and poor protection effect when protecting the cut end of the cable.

[0006] In order to solve the above technical problems, the present invention adopts the following technical scheme: a water-proof cable protective sleeve, comprising a sleeve that can be nested in the outer periphery of the cable, one end of the sleeve is equipped with a clamping member that can clamp the cable, and the other end of the sleeve is threadedly equipped with a plugging member, and the plugging member has a cavity for accommodating the end of the cable; the interior of the sleeve is also provided with an annular ramp and a rubber ring that cooperates with the ramp, one end face of the rubber ring is an inclined surface, and the inclined surface of the rubber ring contacts the surface of the ramp; when the plugging member is tightened, the end of the plugging member can squeeze the rubber ring toward the ramp inside the sleeve.

[0007] When using the present invention, the end of the cable can be inserted into the sleeve, the cable can be clamped by the clamping piece, and then the plugging piece can be screwed in. Since the sleeve is provided with a ring, a ramp and a rubber ring inside, the rubber ring will transfer the force to the ramp when it is axially squeezed by the plugging piece, and the rubber ring will shrink radially under the guidance of the ramp, thereby pressing the cable embedded therein, achieving a higher sealing effect and facilitating operation.

[0008] Furthermore, the sealing piece includes a threaded tube capable of accommodating the end of the cable and a plugging cover located at one end of the threaded tube, the outer circumference of the threaded tube is provided with external threads, the outer circumference of the plugging cover is provided with edges and corners, and the outer circumference of one end of the corresponding sleeve is also provided with edges and corners; since the plugging cover of the sealing piece and one end of the sleeve are both provided with edges and corners, a wrench can be used when screwing the sealing piece into the sleeve, which can increase the axial pressure and make the rubber ring more tightly squeezed on the outer circumference of the cable, thereby providing a better sealing effect.

[0009] Furthermore, a round tube is fixed to one end of the threaded tube away from the plugging cover, the outer diameter of the round tube is consistent with the outer diameter of the rubber ring, and the outer diameter of the round tube is not greater than the thread root diameter of the threaded tube.

[0010] Furthermore, a rubber gasket is provided between the plugging cover and the end of the sleeve; thus, after the plugging piece is tightened, the sealing effect can be further improved by the rubber gasket.

[0011] Furthermore, one end of the sleeve on which the clamp is installed is provided with a radially penetrating through hole, and the clamp includes an eccentric wheel and a handle fixed to the outer periphery of the eccentric wheel, and the eccentric wheel is rotatably installed in the through hole of the sleeve; magnets are installed on the outer wall of the sleeve and the end of the handle away from the eccentric wheel, and when the handle is rotated to fit with the sleeve, the magnet on the handle can be attracted to the magnet on the sleeve.

[0012] Furthermore, a rubber sleeve is provided on the outer periphery of the eccentric wheel; the rubber sleeve can increase the friction coefficient between the outer periphery of the cable and the eccentric wheel, thereby preventing the cable from sliding after being fixed and improving stability.

[0013] Furthermore, there are two clamping members, which are symmetrically located on both sides of the sleeve; therefore, when the end of the cable is inserted into the sleeve, the handles of the two clamping members are pressed down at the same time, and the two eccentric wheels are pressed on the outer circumference of the cable at the same time, so that the cable is centered in the sleeve.

[0014] Furthermore, the middle portion of the outer peripheral surface of the eccentric wheel is recessed toward the inside of the eccentric wheel; thereby, the outer periphery of the eccentric wheel can more evenly squeeze the outer periphery of the cable, which is beneficial to the relative fixation of the sleeve and the cable.

[0015] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages: When using the present invention, the end of the cable can be inserted into the sleeve, the cable can be clamped by the clamping piece, and then the plugging piece can be screwed in. Since the sleeve is provided with a ring, a ramp and a rubber ring inside, the rubber ring will transfer the force to the ramp when it is axially squeezed by the plugging piece, and the rubber ring will shrink radially under the guidance of the ramp, thereby pressing the cable embedded therein, achieving a higher sealing effect and facilitating operation.

[0018] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0019] The present invention discloses a water-proof cable protective sleeve, which comprises a sleeve 1, a clamping member 2 installed on the outer periphery of the sleeve 1, and a plugging member 4 installed at one end of the sleeve 1. The clamping member 2 is located at one end of the sleeve 1, and the plugging member 4 is located at the other end of the sleeve 1. In one example, when the cable is cut off, its end can extend into the sleeve 1, and the sleeve 1 and the cable can be fixed relative to each other through the clamping member 2, and then the plugging member 4 is installed at one end of the sleeve 1 to seal the exposed end of the cable.

[0020] like Figure 1 As shown, the sleeve 1 is a hard tube, and the inner diameter of the sleeve 1 is slightly larger than the diameter of the cable so that the cable can be inserted therein. When the cable is inserted into the sleeve 1, the clamping member 2 can be manipulated to fix the cable and the sleeve 1 relatively. A through hole is provided at one end of the sleeve 1 for mounting the clamping member 2, and the through hole penetrates the sleeve 1 along the radial direction of the sleeve 1. The through hole on the sleeve 1 can realize the installation and matching of the clamping member 2 and the sleeve 1.

[0021] The clamping member 2 includes an eccentric wheel 201 and a handle 202. The rotating shaft of the eccentric wheel 201 is installed in the through hole of the sleeve 1, so that the rotation of the eccentric wheel 201 can be realized. The handle 202 is fixedly connected to one side of the eccentric wheel 201, so that the eccentric wheel 201 can be driven to rotate by rotating the handle 202. When the handle 202 is rotated to fit with the outer arm of the sleeve 1, the lower end of the eccentric wheel 201 is located in the lumen of the sleeve 1. Thus, by rotating the handle 202, the eccentric wheel 201 can squeeze the cable in the sleeve 1, thereby realizing the relative fixation of the cable and the sleeve 1. In addition, magnets are installed on the outer wall of the sleeve 1 and the end of the handle 202 away from the eccentric wheel 201. When the handle 202 is rotated to fit with the sleeve, the magnet on the handle 202 can be attracted with the magnet on the sleeve 1, so that the handle 202 can fit the outer wall of the sleeve 1 reliably and avoid the loosening of the cable.

[0022] Specifically, the outer periphery of the eccentric wheel 201 is wrapped with a rubber sleeve, and the rubber sleeve on the outer periphery of the eccentric wheel 201 can increase the friction coefficient between the outer periphery of the cable and the eccentric wheel 201 to avoid slipping after the cable is fixed to the sleeve 1. It should be understood that a rubber lining can also be provided in the lumen of the sleeve 1 to improve the stability of the cable and the sleeve 1 after they are fixed.

[0023] like Figure 2 As shown, the outer circumference of the eccentric wheel 201 is recessed toward the inside of the eccentric wheel 201, so that when the eccentric wheel 201 rotates, the outer circumference of the eccentric wheel 201 can more evenly squeeze the outer circumference of the cable. This is beneficial to the relative fixation of the sleeve 1 and the cable. In addition, Figure 2 and Figure 3 As shown, there are two clamping members 2, which are symmetrically arranged on both sides of the sleeve 1. After the end of the cable is inserted into the sleeve 1, the handles 202 of the two clamping members 2 are pressed at the same time, so that the two eccentric wheels 201 can be pressed on the outer periphery of the cable at the same time. In this way, the cable can be centered in the sleeve 1, which is conducive to improving the sealing effect of the plugging member 4 on the cable end.

[0024] like Figure 3As shown, the casing 1 is divided into a smooth section 101 and a threaded section 103 according to its inner wall, wherein the inner wall of the threaded section 103 is provided with an internal thread, and the inner diameter of the threaded section 103 is larger than the inner diameter of the smooth section 101. A rubber ring 3 is installed in the threaded section 103, and the inner diameter of the rubber ring 3 is consistent with the inner diameter of the smooth section 101 of the casing 1, so that when the cable passes through the smooth section 101 of the casing 1, the rubber ring 3 can be nested in the outer circumference of the cable.

[0025] like Figure 3 and Figure 4 As shown, the smooth section 101 and the threaded section 103 are transitioned by an annular ramp 102. The ramp 102 forms an annular ramp inside the sleeve 1, so that when the rubber ring 3 is axially squeezed, the ramp 102 can guide the rubber ring 3, so that the radial size of the rubber ring 3 is reduced and pressed against the outer periphery of the cable. In addition, one end face of the rubber ring 3 is an inclined surface, and the inclined surface of the rubber ring 3 contacts the inclined surface of the ramp 102, so that when the rubber ring 3 is axially squeezed, the contact between the two inclined surfaces can guide the rubber ring 3 to keep the rubber ring 3 pressed against the outer periphery of the cable more stably.

[0026] like Figure 5 As shown, the plugging member 4 includes a threaded tube 402 and a plugging cover 403 located at one end of the threaded tube 402, wherein the inner diameter of the threaded tube 402 is slightly larger than the diameter of the cable, and when the end of the cable passes through the rubber ring 3, it can extend into the threaded tube 402. The outer circumference of the threaded tube 402 is provided with an external thread, and the external thread of the threaded tube 402 cooperates with the internal thread of the end of the sleeve 1, thereby enabling the plugging member 4 to be installed at the end of the threaded sleeve 1. One end of the plugging cover 403 is provided with an edge, and correspondingly, one end of the sleeve 1 is also provided with an edge, thereby enabling the plugging member 4 to be screwed into the sleeve 1 by a wrench, providing a greater axial pressure for the rubber ring 3, so that the rubber ring 3 is more tightly squeezed on the outer circumference of the cable. It should be understood that a rubber gasket can also be provided between the plugging cover and the end of the sleeve, so that after the plugging member 4 is tightened, the sealing effect can be further improved by the rubber gasket.

[0027] In addition, the plugging member 4 further comprises a round tube 401, which is coaxially arranged with the threaded tube 402 and fixed to one end of the threaded tube 402 away from the plugging cap 403. The outer diameter of the round tube 401 is consistent with the outer diameter of the rubber ring 3, and the outer diameter of the round tube 401 is not greater than the diameter of the thread root of the threaded tube 402. Thus, when the plugging member 4 is screwed into the casing 1, it can be ensured that the end of the plugging member 4 is in contact with the rubber ring 3.
