Description

Technical Field

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

[0002] With the advancement of economy and technology and the widespread use of electrical appliances, the application of power cords has also increased. Power cords are wires that transmit current. Although power cords are just accessories for electrical appliances, they play a vital role in their use. After long-term use, the connectors of power cords are prone to wear and breakage, so protective sleeves and other protective devices are often installed.

[0003] An existing patent (publication number: CN216251364U) discloses a power cord interface protection device, specifically relating to the field of power cord technology. It includes a housing, a power cord, and an interface shell disposed on the power cord. The housing comprises a left protective shell and a right protective shell hinged to one side of the left protective shell. A movable groove is provided inside the left protective shell. An arc-shaped locking rod passes through the movable groove, the left protective shell, and the right protective shell. A connecting rod is fixedly connected to the outer surface of the arc-shaped locking rod. One end of the connecting rod passes through the movable groove and is fixedly connected to a button block. Elastic locking elements are provided at the top of both the left and right protective shells.

[0004] Although this application can effectively disassemble and use the interface as needed, and can effectively block and shield the interface to avoid direct contact, thus protecting the power cord interface from easy bending and preventing breakage, it cannot protect the interface when it is not in use. This allows airborne dust particles to enter the socket or pin gap, forming an insulating layer, which leads to increased resistance and decreased conductivity. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a power cable interface protection device, which has the advantages of protecting the interface end when the interface is not in use. This solves the problem that existing protection devices cannot protect the interface end when the interface is not in use, allowing airborne dust particles to enter the socket or pin gap, forming an insulating layer, which leads to increased resistance and decreased conductivity.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power cable interface protection device, comprising a support frame rotatably connected to the side of the cable body, a side guard plate movably disposed on the side of the support frame, a top plate disposed on the inner side of the side guard plate, and the top plate overlapping the upper surface of the cable body.

[0007] On the outer side of the support frame, a first fixing frame and a second fixing frame are symmetrically arranged. The first fixing frame and the second fixing frame are clamped with each other. There are two sets of the support frame, side guard plates and top plates, and they are symmetrically arranged on the surface of the cable body. The two sets of the support frames, the side guard plates and the top plates are fixed by the first fixing frame and the second fixing frame.

[0008] Furthermore, both the support frame and the side guard plate are in an "L" shape. The side surface of the top plate is fitted with the side guard plate, and the surface of the side guard plate is fitted with the upper surface of another side guard plate. The two sets of the top plates and the side guard plates form a receiving cavity, and the cable body is arranged inside the receiving cavity.

[0009] Through the above solution, the side guard plate and the top plate can form a semi-enclosed or approximately closed receiving cavity around the interface end, directly covering key parts such as jacks and pins that are prone to dust accumulation, constructing a physical barrier to block the intrusion path of suspended dust particles in the air, so as to protect the interface end of the cable body.

[0010] Furthermore, a first fixing groove is formed on the side surface of the support frame, and second fixing grooves are formed on both the upper surface and the lower surface of the side guard plate. Both the first fixing frame and the second fixing frame are in an "L" shape, and both the first fixing frame and the second fixing frame are perpendicular to the support frame. The side surfaces of the first fixing frame and the second fixing frame are clamped inside the first fixing groove and the second fixing groove respectively.

[0011] Through the above solution, the vertical sides of the first fixing frame and the second fixing frame are clamped in the fixing groove formed on the side surface of the support frame, and the horizontal sides are clamped in the second fixing grooves formed on the upper surface and the lower surface of the side guard plate, forming clamping on both sides, which can effectively resist the horizontal / vertical stress generated by external collision at the power interface, and avoid loosening between the two sets of the support frames, the side guard plates and the top plates, thus affecting the protection of the interface end of the cable body.

[0012] Furthermore, an installation groove is formed on the end face of the first fixing frame, a connecting block corresponding to the installation groove is fixed on the end face of the second fixing frame, the connecting block penetrates inside the installation groove, a clamping groove is formed on the inner wall of the installation groove, and an elastic clamping block corresponding to the clamping groove is arranged on the side surface of the connecting block. The elastic clamping block is clamped inside the clamping groove.

[0013] Through the above solution, align the connecting block of the second fixing frame with the installation groove of the first fixing frame, and gently push along the axial direction to complete the assembly. At the same time, the elastic clamping block generates a small elastic deformation under the extrusion of the clamping groove during the pushing process, and relies on its own elasticity to reset and clamp tightly after completely entering the clamping groove. The whole process does not require any tools, reducing the time cost of production and assembly.

[0014] Furthermore, a first slider is fixed to the inner wall of the support frame, and a first groove is provided on the outer surface of the side guard plate. The first slider moves inside the first groove, and the side guard plate moves on the side of the support frame through the first slider and the groove. The first slider and the first groove are both "T" shaped, and there are two sets of the first slider and the first groove, which are symmetrically arranged.

[0015] With the above solution, the side guard plate can move on the side of the support frame through the first slider and the first slide groove. After the support frame is flipped, the side guard plate can move synchronously with the position of the support frame, thereby protecting the wiring of the cable body.

[0016] Furthermore, a second slider is fixed to the side of the top plate, and a second groove corresponding to the second slider is opened on the inner wall of the side guard plate. The second slider moves inside the second groove. Both the second slider and the second groove are "T" shaped. The top plate moves inside the side guard plate through the first slider and the first groove.

[0017] Furthermore, the upper surface of the side guard plate is provided with a placement groove corresponding to the cable. The placement groove is semi-circular, and two placement grooves can form a wire hole, through which the wiring of the cable body can be inserted.

[0018] Through the above solution, the semi-circular placement groove, with its "semi-enclosed + limiting" design, can accurately fix the lateral position of the cable body connection. When the connection is inserted into the wire hole, its outer wall is in close contact with the inner wall of the placement groove. The arc-shaped structure of the placement groove generates a radial constraint force on the cable, restricting the cable from swaying in the horizontal direction, preventing the interface from being damaged due to cable swaying, and extending the service life of the interface.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] This power cable interface protection device uses two symmetrically arranged "U"-shaped support frames, side guards, and a top plate, which are fixed by the snap-fit ​​of the first and second fixing frames to form a receiving cavity around the interface end. The inner side of the side guards fits against the side of the cable body interface end, and the top plate overlaps the upper surface of the cable body interface end. The side guards reduce the splicing gap through surface fitting. The top plate directly covers the upper surface of the interface end, and the side guards cover the side. Together, the three components "wrap" the socket, pins, and other key parts in the receiving cavity, constructing a physical barrier and blocking the intrusion path of suspended dust particles in the air.

[0035] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Please see Figure 1 , Figure 2 and Figure 3, a power cable interface protection device in this embodiment includes a support frame 2 rotatably connected to the side of the cable body 1. A side guard plate 3 is movably arranged on the side of the support frame 2. A top plate 4 is arranged inside the side guard plate 3, and the top plate 4 overlaps the upper surface of the cable body 1. First fixing frames 5 and second fixing frames 6 are symmetrically arranged on the outer side of the support frame 2, and the first fixing frame 5 and the second fixing frame 6 are clamped with each other. There are two groups of the support frame 2, the side guard plate 3 and the top plate 4, and they are symmetrically arranged on the surface of the cable body 1. The two groups of the support frame 2, the side guard plate 3 and the top plate 4 are fixed by the first fixing frame 5 and the second fixing frame 6. Through the two groups of symmetrically arranged "C"-shaped support frames 2, side guard plates 3 and top plates 4, and through the clamping and fixing of the first fixing frame 5 and the second fixing frame 6, a receiving cavity is formed around the interface end. Among them, the inner side of the side guard plate 3 is fitted to the side of the interface end of the cable body 1, the top plate 4 overlaps the upper surface of the interface end of the cable body 1, the splicing gap is reduced by the surface fitting between the side guard plates 3, the top plate 4 directly covers the upper end surface of the interface end, and the side guard plates 3 cover the sides. The three together "wrap" key parts such as jacks and pins in the receiving cavity, constructing a physical barrier and blocking the intrusion path of suspended dust particles in the air.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 , both the support frame 2 and the side guard plate 3 are "C"-shaped. The side surface of the top plate 4 is fitted to the side guard plate 3, and the surface of the side guard plate 3 is fitted to the upper surface of another side guard plate 3. The two groups of the top plate 4 and the side guard plate 3 form a receiving cavity, and the cable body 1 is arranged inside the receiving cavity. Through the side guard plate 3 and the top plate 4, a semi-enclosed or approximately closed receiving cavity can be formed around the interface end, directly covering key parts such as jacks and pins that are prone to dust accumulation, constructing a physical barrier to block the intrusion path of suspended dust particles in the air, so as to protect the interface end of the cable body 1; a first fixing groove 201 is opened on the side surface of the support frame 2, and second fixing grooves 304 are opened on both the upper surface and the lower surface of the side guard plate 3. Both the first fixing frame 5 and the second fixing frame 6 are "C"-shaped, and both the first fixing frame 5 and the second fixing frame 6 are perpendicular to the support frame 2. The side surfaces of the first fixing frame 5 and the second fixing frame 6 are clamped inside the first fixing groove 201 and the second fixing groove 304. The vertical sides of the first fixing frame 5 and the second fixing frame 6 are clamped in the fixing groove opened on the side surface of the support frame 2, and the horizontal sides are clamped in the second fixing grooves 304 opened on the upper surface and the lower surface of the side guard plate 3, forming clamping on both sides, which can effectively resist the transverse / longitudinal stress generated by external collisions at the power supply interface, and avoid loosening between the two groups of the support frame 2, the side guard plate 3 and the top plate 4, thus affecting the protection of the interface end of the cable body 1.

[0038] Please refer to Figure 2 , Figure 4 and Figure 5The first fixing frame 5 has an installation groove 501 on its end face, and the second fixing frame 6 has a connecting block 601 corresponding to the installation groove 501 fixed on its end face. The connecting block 601 passes through the installation groove 501. The inner wall of the installation groove 501 has a slot 502. The side of the connecting block 601 is provided with an elastic locking block 602 corresponding to the slot 502. The elastic locking block 602 is engaged in the slot 502. The connecting block 601 of the second fixing frame 6 is aligned with the installation groove 501 of the first fixing frame 5, and the assembly can be completed by gently pushing it along the axial direction. At the same time, the elastic locking block 602 is squeezed by the slot 502 during the pushing process and undergoes a slight elastic deformation until it is fully inserted into the slot 502 and then resets and locks itself due to its own elasticity. The whole process does not require any tools, which reduces the time cost of production and assembly.

[0039] Please see Figure 2 and Figure 3 The inner wall of the support frame 2 is fixed with a first slider 202, and the outer surface of the side guard plate 3 is provided with a first groove 301. The first slider 202 moves inside the first groove 301. The side guard plate 3 moves on the side of the support frame 2 through the first slider 202 and the groove. The first slider 202 and the first groove 301 are both "T" shaped. There are two sets of the first slider 202 and the first groove 301, which are symmetrically arranged. Through the first slider 202 and the first groove 301, the side guard plate 3 can move on the side of the support frame 2. After the support frame 2 is flipped, the side guard plate 3 can move synchronously with the position of the support frame 2, thereby protecting the wiring of the cable body 1.

[0040] Please see Figure 2 , Figure 6 and Figure 7 The top plate 4 has a second slider 401 fixed on its side. The inner wall of the side guard plate 3 has a second groove 303 corresponding to the second slider 401. The second slider 401 moves inside the second groove 303. Both the second slider 401 and the second groove 303 are "T" shaped. The top plate 4 moves inside the side guard plate 3 through the first slider 202 and the first groove 301. The upper surface of the side guard plate 3 has a placement groove 302 corresponding to the cable. The placement groove 302 is semi-circular, and the two placement grooves 302 can form a wire hole. The wire of the cable body 1 can be inserted into the wire hole. The semi-circular placement groove 302 can accurately fix the lateral position of the wire of the cable body 1 through the "semi-enclosed + limiting" design. When the wire is inserted into the wire hole, its outer wall is in close contact with the inner wall of the placement groove 302. The arc structure of the placement groove 302 generates a radial constraint force on the cable, restricting the cable from shaking in the horizontal direction, avoiding damage to the interface due to cable shaking, and extending the service life of the interface.

[0041] The working principle of the above embodiment is as follows: First, the support frame 2 is flipped so that it is positioned close to the interface end of the cable body 1. Then, the position of the side guard plate 3 is adjusted by the first slider 202 and the second slider 401 so that the lower surface of the upper side guard plate 3 is in contact with the upper surface of the lower side guard plate 3. Then, the position of the top plate 4 is adjusted by the second slider 401 and the second slide groove 303 so that the lower surface of the top plate 4 is in contact with the upper and lower surfaces of the interface end of the cable body 1. Then, the operator moves the first fixing frame 5 and the second fixing frame 6 closer from both sides and makes the first fixing frame 5 and the second fixing frame 6 closer together. The frame 6 is respectively snapped into the first fixing groove 201 opened on both sides of the support frame 2 and the second fixing groove 304 opened on the surface of the side guard plate 3. Then, the connecting block 601 of the second fixing frame 6 is aligned with the mounting groove 501 of the first fixing frame 5, and the assembly is completed by gently pushing it along the axial direction. At the same time, the elastic block 602 is squeezed by the groove 502 during the pushing process and generates a slight elastic deformation until it is fully inserted into the groove 502 and then resets and locks itself by its own elasticity, thus completing the fixing of the first fixing frame 5 and the second fixing frame 6, thereby fixing the upper and lower sets of support frames 2, side guard plates 3 and top plate 4.

[0042] When the interface end of the cable body 1 is needed, the operator only needs to press the elastic block 602 to disengage it from the slot 502. The operator can then remove the first fixing bracket 5 and the second fixing slot 304 from the surface of the support frame 2. The operator then flips the support frame 2, causing the side guard plate 3 and top plate 4 to rotate synchronously. The operator then adjusts the positions of the side guard plate 3 and top plate 4 using the first slider 202, the first sliding groove 301, the second slider 401, and the second sliding groove 303, respectively, so that after flipping, the two sets of side guard plates 3 and top plate 4 form the configuration shown in the attached figure. Figure 7 The cavity shown protects the wiring of the cable body 1. Meanwhile, the placement grooves 302 on the surfaces of the two side guards 3 can form a wire-passing hole to accommodate the wiring of the cable body 1.
