Description

Technical Field

[0001] This utility model relates to the field of cable protection equipment technology, and in particular to an insulating protective connector. Background Technology

[0002] Cables are a general term for conductors and cables, serving as the core carriers for power transmission, signal transmission, and equipment connection. They are widely used in power systems, communication networks, industrial equipment, and daily life. In practical production applications, to improve operational safety, exposed parts of cables need to be treated. One common method is to wrap electrical tape around the exposed areas of the cable. While this method can cover the exposed areas, the tape's adhesiveness decreases with age, making it prone to detachment and accidental electric shock to workers. Another method is to use silicone protective sleeves to protect the exposed areas. However, this not only fails to guarantee insulation but also allows the cable to easily detach from the sleeve, compromising operational safety. A third method uses connectors to protect the exposed areas. While this ensures insulation, to prevent the cable from detaching after installation, the connector is usually clipped onto the cable corresponding to the exposed area. This makes removing the connector difficult and inefficient, and there is a risk of the cable's electrical cores scratching the operator during disassembly, further reducing operational safety. Utility Model Content

[0003] The purpose of this utility model is to provide an insulating protective connector that can protect exposed areas on cables and ensure operational safety. Furthermore, the insulating protective connector is easy to disassemble after use and has high disassembly efficiency.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Insulating protective connectors, used to protect cables, include:

[0006] A protective cylinder, wherein the first end of the protective cylinder is a closed end;

[0007] The limiting component includes multiple elastic limiting members, which are spaced apart circumferentially inside the protective cylinder and cooperate with each other to form a limiting space.

[0008] An auxiliary withdrawal tube, the first end of which is movably inserted into the protective tube;

[0009] The exposed end of the cable can be sequentially threaded through the auxiliary withdrawal tube and the limiting space;

[0010] The auxiliary withdrawal cylinder moves relative to the protective cylinder along direction A and has a first position and a second position;

[0011] When the auxiliary withdrawal cylinder is located in the first position, the limiting component is in a locked state or an initial state, and the limiting component in the locked state can clamp the cable.

[0012] When the auxiliary withdrawal cylinder is in the second position, the auxiliary withdrawal cylinder abuts against the plurality of limiting members and can expand the limiting space.

[0013] As a further technical solution, the limiting component also includes an auxiliary sleeve, which is disposed at the second end of the protective cylinder. The first end of the auxiliary withdrawal cylinder is inserted into the auxiliary sleeve and can abut against multiple limiting members. All of the multiple limiting members are connected to the first end of the auxiliary sleeve.

[0014] As a further technical solution, each of the limiting components includes a limiting plate and a limiting part. The first end of each limiting plate is connected to the first end of the auxiliary sleeve, and the second end extends along the A direction. The limiting part is disposed on the inner wall corresponding to the second end of the limiting plate, and the multiple limiting parts cooperate with each other to form the limiting space.

[0015] As a further technical solution, the inner wall of the first end of the auxiliary sleeve is provided with at least one clearance opening, and the outer wall of the first end of the auxiliary withdrawal cylinder is correspondingly provided with a withdrawal protrusion.

[0016] When the auxiliary withdrawal cylinder is in the first position, the withdrawal protrusion engages with the corresponding clearance opening.

[0017] When the auxiliary withdrawal cylinder is in the second position, the withdrawal protrusion disengages from the corresponding clearance opening and abuts against the inner wall of the limiting plate.

[0018] As a further technical solution, the side wall of the withdrawal protrusion near the limiting member is configured as a first guide surface, the first guide surface is configured as an arc surface, or, along direction A, the first guide surface is configured as an inclined surface that is inclined in a direction away from the axis of the protective cylinder.

[0019] As a further technical solution, along direction A, the inner wall of at least one of the limiting plates is inclined toward the axis of the protective cylinder;

[0020] Pushing the auxiliary withdrawal cylinder along direction A allows the outer wall of the auxiliary withdrawal cylinder to abut against the inner wall of each of the limiting plates.

[0021] As a further technical solution, each of the limiting parts is provided with an anti-slip component on the side opposite to the limiting plate.

[0022] As a further technical solution, each of the limiting parts is provided with a second guide surface near the side wall of the auxiliary sleeve. The second guide surface is provided as an arc surface, or, along direction A, the second guide surface is provided as an inclined surface that is inclined in a direction away from the axis of the protective cylinder.

[0023] As a further technical solution, the auxiliary sleeve is threaded to the second end of the protective sleeve, and the second end of the auxiliary sleeve is provided with a positioning protrusion.

[0024] As a further technical solution, at least one compensation groove is provided on the end face of the first end of the auxiliary withdrawal cylinder, and the compensation groove extends toward the second end of the auxiliary withdrawal cylinder.

[0025] As a further technical solution, each of the limiting members is configured as a plate, with the first end of each limiting member fixedly connected to the inner wall of the protective cylinder, and the second end extending towards the axis of the protective cylinder, pushing the auxiliary withdrawal cylinder to abut against the multiple limiting members along direction A, so that each limiting member bends along direction A.

[0026] As a further technical solution, the second end of the auxiliary withdrawal cylinder is provided with an auxiliary limiting handle, which can be limited and abutted against the second end of the protective cylinder.

[0027] Beneficial effects: Since the first end of the protective cylinder is a closed end, multiple elastic limiting components are spaced apart along the circumference of the protective cylinder, and the first end of the auxiliary withdrawal cylinder is movably inserted into the protective cylinder. Therefore, when it is necessary to shield and protect the exposed end of the cable, it is only necessary to pass the exposed end of the cable through the auxiliary withdrawal cylinder and limit its insertion into the limiting space; when it is necessary to remove the insulation protection connector from the exposed end of the cable, the auxiliary withdrawal cylinder is moved from the first position to the second position inside the protective cylinder, that is, the first end of the auxiliary withdrawal cylinder abuts against the multiple limiting components, causing the multiple limiting components to elastically deform, thereby expanding the limiting space, and thus directly withdrawing the exposed end of the cable from the limiting space, thereby detaching the insulation protection connector from the cable. Throughout the process, the protective cylinder shields and protects the exposed end of the cable, confining it within a limited space. This prevents the exposed end from detaching from the protective cylinder during production, thus avoiding accidental electric shock to the operator and improving operational safety. Simultaneously, due to the elasticity of multiple components, moving the auxiliary withdrawal cylinder to its second position within the protective cylinder allows the exposed end of the cable to detach from the insulating protective connector. This simplifies and facilitates disassembly, improving cleaning efficiency. Furthermore, the entire disassembly process only requires the operator to move the auxiliary withdrawal cylinder to change its position within the protective cylinder, without touching the exposed end of the cable, preventing injury from the cable core and further enhancing operational safety.

[0040] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0041] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0042] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0043] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0044] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0045] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0046] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0047] Combination Figures 1 to 6 As shown, the insulating protective connector provided in this embodiment is used to protect the exposed areas on the cable 10 and ensure operational safety. The insulating protective connector is also easy to disassemble after use and has high disassembly efficiency. The insulating protective connector includes a protective cylinder 100, a limiting component, and an auxiliary withdrawal cylinder 300: the first end of the protective cylinder 100 is a closed end; the limiting component includes multiple elastic limiting members 200, which are spaced apart circumferentially within the protective cylinder 100 and cooperate with each other to form a limiting space 201; the first end of the auxiliary withdrawal cylinder 300 is movably inserted into the protective cylinder 100; the exposed end of the cable 10 passes through the auxiliary withdrawal cylinder 300 and the limiting space 201 in sequence, and the auxiliary withdrawal cylinder 300 moves relative to the protective cylinder 100 in direction A to have a first position and a second position; wherein, when the auxiliary withdrawal cylinder 300 is in the first position, the limiting component is in a locked state or an initial state, and the limiting component in the locked state can clamp the cable 10; when the auxiliary withdrawal cylinder 300 is in the second position, the auxiliary withdrawal cylinder 300 abuts against the multiple limiting members 200 and can expand the limiting space 201.

[0048] Since the first end of the protective cylinder 100 is a closed end, multiple elastic limiting members 200 are spaced apart circumferentially inside the protective cylinder 100, and the first end of the auxiliary withdrawal cylinder 300 is movably inserted inside the protective cylinder 100. Therefore, when it is necessary to shield and protect the exposed end of the cable 10, it is only necessary to pass the exposed end of the cable 10 through the auxiliary withdrawal cylinder 300 and limit it in the limiting space 201; when it is necessary to remove the insulating protective connector from the exposed end of the cable 10, the auxiliary withdrawal cylinder 300 is moved from the first position to the second position inside the protective cylinder 100, that is, the first end of the auxiliary withdrawal cylinder 300 abuts against the multiple limiting members 200, causing the multiple limiting members 200 to undergo elastic deformation, thereby expanding the limiting space 201, and thus directly removing the exposed end of the cable 10 from the limiting space 201, thereby detaching the insulating protective connector from the cable 10. Throughout the process, the protective cylinder 100 shields and protects the exposed end of the cable 10, and the exposed end of the cable 10 is confined within the limiting space 201. During production, this prevents the exposed end of the cable 10 from detaching from the protective cylinder 100 on its own, thus preventing the operator from accidentally touching the exposed end of the cable 10 and getting an electric shock, thereby improving operational safety. At the same time, since multiple elastic components are elastic, moving the auxiliary withdrawal cylinder 300 to its second position within the protective cylinder 100 allows the exposed end of the cable 10 to detach from the insulating protective connector. The process of disassembling the insulating protective connector is simple and convenient, improving disassembly and cleaning efficiency. Furthermore, the entire disassembly process only requires the operator to move the auxiliary withdrawal cylinder 300 to change its position within the protective cylinder 100, without touching the exposed end of the cable 10, thereby preventing the cable 10 core from scratching the operator and further improving operational safety.

[0049] When the auxiliary withdrawal cylinder 300 is in the first position, if the exposed end of the cable 10 passes into the limiting space 201, the limiting component is in a locked state, and multiple limiting components 200 cooperate to limit the exposed end of the cable 10. If the cable 10 is not inserted into the auxiliary withdrawal cylinder 300, or if the cable 10 is inserted into the auxiliary withdrawal cylinder 300 but the exposed end of the cable 10 does not pass into the limiting space 201, the limiting component is in the initial state. Furthermore, moving the auxiliary withdrawal cylinder 300 along direction A allows it to move from the first position to the second position within the protective cylinder 100.

[0050] To facilitate the passage of the exposed end of the cable 10 through the auxiliary withdrawal cylinder 300 and its placement in the limiting space 201, the auxiliary withdrawal cylinder 300 can be moved to the second position to expand the limiting space 201. After the exposed end of the cable 10 is passed through the limiting space 201, the auxiliary withdrawal cylinder 300 can be moved again to move from the second position to the first position within the protective cylinder 100, so that the limiting component is in a locked state.

[0051] To improve the overall insulation performance of the insulating protective joint, all components in the insulating protective joint are made of insulating materials, including but not limited to rubber, polyvinyl chloride (PVC), polyethylene (PE), cross-linked polyethylene (XLPE), polypropylene (PP), etc., without specific limitations here.

[0052] The number of limiting members 200 can be increased or decreased according to actual needs. In this embodiment, eight limiting members 200 are used as an example for explanation.

[0053] Regarding the specific setting of the limiting member 200, this embodiment provides three implementation methods, as follows:

[0054] First implementation method

[0055] Combination Figures 1 to 5 As shown, the limiting assembly also includes an auxiliary sleeve 400, which is disposed at the second end of the protective cylinder 100. The first end of the auxiliary withdrawal cylinder 300 is inserted into the auxiliary sleeve 400 and can abut against eight limiting members 200. All eight limiting members 200 are connected to the first end of the auxiliary sleeve 400. By setting the auxiliary sleeve 400, the limiting and protection effect on the exposed end of the cable 10 is ensured, while facilitating the placement of the eight limiting members 200 inside the protective cylinder 100, thereby reducing the processing and assembly difficulty of the eight limiting members 200.

[0056] Specifically, each of the eight limiting members 200 includes a limiting plate 210 and a limiting part 220. The first end of each of the eight limiting plates 210 is connected to the first end of the auxiliary sleeve 400, and the second end of each extends along direction A. The limiting part 220 is disposed on the inner wall of the corresponding second end of the limiting plate 210. The eight limiting parts 220 cooperate with each other to form a limiting space 201. Since the contact area between the limiting part 220 and the cable 10 is small, when the cable 10 is limited in the limiting space 201, the range of motion can be increased. The stress between each limiting part 220 and the cable 10 causes each limiting part 220 to press against the outer wall of the cable 10, thereby further improving the limiting effect on the cable 10. At the same time, since each limiting part 220 is located on the inner wall of the second end of the corresponding limiting plate 210, when the cable 10 is limited in the limiting space 201, each limiting plate 210 can have a large bending deformation, thereby providing a large clamping force to the corresponding limiting part 220, so as to further improve the limiting effect on the cable 10.

[0057] Specifically, the inner wall of the first end of the auxiliary sleeve 400 is provided with at least one clearance opening 410, and the outer wall of the first end of the auxiliary withdrawal cylinder 300 is correspondingly provided with a withdrawal protrusion 310. When the auxiliary withdrawal cylinder 300 is in the first position, the withdrawal protrusion 310 is engaged with the corresponding clearance opening 410; when the auxiliary withdrawal cylinder 300 is in the second position, the withdrawal protrusion 310 disengages from the corresponding clearance opening 410 and abuts against the inner wall of the limiting plate 210. With this configuration, pushing the auxiliary withdrawal cylinder 300 along direction A causes the withdrawal protrusion 310 to withdraw from the corresponding clearance opening 410, which not only opens the corresponding limiting plate 210 in a direction away from the axis of the protective cylinder 100, but also prevents the auxiliary withdrawal cylinder 300 from detaching from the auxiliary sleeve 400 on its own.

[0058] For example, the retraction protrusion 310 may abut against the inner wall of at least one limiting plate 210, such as two or three.

[0059] In this embodiment, when the auxiliary withdrawal cylinder 300 abuts against the eight limiting members 200, in order to ensure that the eight limiting members 200 have sufficient deformation space to facilitate separation from the exposed end of the cable 10, the inner diameter of the protective cylinder 100 is larger than the outer diameter of the auxiliary withdrawal cylinder 300.

[0060] In this embodiment, in order to ensure the limiting effect of the limiting space 201 on the exposed end of the cable 10, the maximum distance between the two limiting parts 220 that are arranged opposite to each other is slightly smaller than the diameter of the exposed end of the cable 10. For example, when the diameter of the exposed end of the cable 10 is set to 9cm, the maximum distance between the two limiting parts 220 that are arranged opposite to each other does not exceed 8.5cm.

[0061] In this embodiment, in order to ensure that the first end of the auxiliary withdrawal cylinder 300 can pass through the auxiliary sleeve 400 and be inserted into the protective cylinder 100, the inner diameter of the auxiliary withdrawal cylinder 300 is slightly larger than the outer diameter of the auxiliary withdrawal cylinder 300. For example, when the outer diameter of the auxiliary withdrawal cylinder 300 is set to 10cm, the inner diameter of the auxiliary withdrawal cylinder 300 is correspondingly set to 10.2cm.

[0062] In this embodiment, the auxiliary sleeve 400 is provided with two clearance openings 410. The two clearance openings 410 are symmetrically arranged about the axis of the auxiliary sleeve 400. The outer wall of the first end of the auxiliary withdrawal cylinder 300 is provided with two withdrawal protrusions 310 corresponding to the two clearance openings 410. Each clearance opening 410 corresponds to at least one limiting plate 210. When the auxiliary withdrawal cylinder 300 is pushed along direction A, one withdrawal protrusion 310 can abut against the inner wall of at least one limiting plate 210.

[0063] When the withdrawal protrusion 310 is engaged with the corresponding clearance opening 410, all eight limiting plates 210 are in their original state; when the exposed end of the cable 10 passes through the auxiliary withdrawal cylinder 300 and is inserted into the limiting space 201, and the second ends of all eight limiting plates 210 are inclined in a direction away from the axis of the protective cylinder 100, and the eight limiting parts 220 abut against the cable 10, so as to limit the exposed end of the cable 10 to the limiting space 201; when the exposed end of the cable 10 needs to be withdrawn from the protective cylinder 300, the cable 10 is in a position to be withdrawn from the protective cylinder 300. When the cable 10 is disengaged, the auxiliary withdrawal cylinder 300 is pushed along direction A. As the auxiliary withdrawal cylinder 300 is continuously pushed, the withdrawal protrusion 310 is withdrawn from the corresponding clearance opening 410 and abuts against the inner wall of the corresponding limiting plate 210. This causes the second end of the corresponding limiting plate 210 to bend further away from the axis of the protective cylinder 100, so that the corresponding limiting part 220 no longer abuts against the cable 10, thereby facilitating the withdrawal of the exposed end of the cable 10 from the limiting space 201. After the exposed end of the cable 10 is disengaged from the protective connector, the auxiliary withdrawal cylinder 300 is retracted in the opposite direction of direction A until the withdrawal protrusion 310 is once again engaged with the corresponding clearance opening 410, preventing the auxiliary withdrawal cylinder 300 from disengaging from the protective cylinder 100 or the auxiliary sleeve 400, thus facilitating the next use of the insulating protective connector.

[0064] In other embodiments, the number of clearance openings 410 may be increased or decreased according to actual needs, and is not limited to the two illustrated in this embodiment.

[0065] Preferably, combined with Figures 1 to 5 As shown, when the auxiliary withdrawal cylinder 300 is pushed along direction A, in order to improve the convenience of withdrawal protrusion 310 withdrawing from the corresponding clearance opening 410, the side wall of withdrawal protrusion 310 near the limiting member 200 is configured as a first guide surface 311. The eight first guide surfaces 311 are configured as arc surfaces; or, along direction A, the eight first guide surfaces 311 are configured as inclined surfaces tilted in a direction away from the axis of the protective cylinder 100; or, some of the first guide surfaces 311 are configured as arc surfaces, and the other part of the first guide surfaces 311 are configured as inclined surfaces tilted in a direction away from the axis of the protective cylinder 100 along direction A.

[0066] In other embodiments, the sidewalls of the clearance opening 410 near the limiting member 200 may be configured as arc-shaped surfaces, or the sidewalls of the clearance opening 410 near the limiting member 200 may be configured as inclined auxiliary inclined surfaces that are inclined in the direction of A toward the axis of the protective cylinder 100.

[0067] Preferably, at least one compensation groove 320 is provided on the end face of the first end of the auxiliary withdrawal cylinder 300, and the compensation groove 320 extends toward the second end of the auxiliary withdrawal cylinder 300.

[0068] The number of compensation grooves 320 can be adaptively set according to actual needs. In this embodiment, two compensation grooves 320 are set at the first end of the auxiliary withdrawal cylinder 300 as an example. Specifically, in conjunction with Figure 4 As shown, the first end of the auxiliary withdrawal cylinder 300 is provided with two compensation grooves 320, which are symmetrically arranged about the axis of the auxiliary withdrawal cylinder 300 so that the first end of the auxiliary withdrawal cylinder 300 is bilobed. Since the outer wall of the first end of the auxiliary withdrawal cylinder 300 is provided with a withdrawal protrusion 310, when the first end of the auxiliary withdrawal cylinder 300 is inserted into the auxiliary sleeve 400, the bilobed first end of the auxiliary withdrawal cylinder 300 is compressed in the direction closer to its axis. When the first end of the auxiliary withdrawal cylinder 300 is inserted into the auxiliary sleeve 400 and the withdrawal protrusion 310 is engaged with the corresponding clearance opening 410, the compressed bilobed auxiliary withdrawal cylinder 300 returns to its original shape so that the exposed end of the cable 10 can pass through the auxiliary withdrawal cylinder 300 and be confined in the limiting space 201. By setting two compensation grooves 320, the convenience of inserting the first end of the auxiliary withdrawal cylinder 300 into the auxiliary sleeve 400 is improved, while ensuring the structural strength of the auxiliary withdrawal cylinder 300 itself. When the auxiliary withdrawal cylinder 300 is pushed in the A direction to abut against the multiple limiting members 200, the first end of the auxiliary withdrawal cylinder 300 is prevented from deforming due to the abutment force, which would increase the difficulty of disassembling the insulating protective joint.

[0069] Preferably, each of the eight limiting portions 220 is provided with an anti-slip element 230 on the side opposite to the limiting plate 210. By providing the anti-slip element 230, the friction between the corresponding limiting portion 220 and the exposed end of the cable 10 is increased, thereby further improving the limiting effect of the limiting space 201 on the exposed end of the cable 10 inserted in the limiting space 201. The anti-slip element 230 can be formed by providing a serrated, wavy, or grid-like texture on the side of the limiting portion 220 opposite to the limiting plate 210; alternatively, a rubber pad, polyurethane (PU) sheet, or sandpaper can be adhered to the side of the limiting portion 220 opposite to the limiting plate 210; or a rubber block, nylon block, or metal protrusion can be fixedly provided on the side of the limiting portion 220 opposite to the limiting plate 210. The specific configuration can be adapted according to actual needs and is not specifically limited here.

[0070] Preferably, combined with Figure 1 and Figure 2As shown, in order to improve the convenience of inserting the exposed end of the cable 10 into the limiting space 201, the side walls of the eight limiting parts 220 near the auxiliary sleeve 400 are all configured as second guide surfaces 221, and the eight second guide surfaces 221 are configured as arc surfaces; or, along the A direction, the eight second guide surfaces 221 are configured as inclined surfaces that are inclined in the direction away from the axis of the protective cylinder 100; or, some of the second guide surfaces 221 are configured as arc surfaces, and other parts of the second guide surfaces 221 are configured as inclined surfaces that are inclined in the direction away from the axis of the protective cylinder 100 along the A direction.

[0071] Preferably, the auxiliary sleeve 400 is threadedly connected to the second end of the protective sleeve 100. This arrangement facilitates the installation of the limiting component inside the protective sleeve 100 and prevents the auxiliary sleeve 400 from wobbling within the protective sleeve 100. Furthermore, in special circumstances, if pushing the auxiliary withdrawal sleeve 300 fails to increase the cross-sectional area of ​​the limiting space 201 in direction A, the auxiliary sleeve 400 can be directly unscrewed from the protective sleeve 100, and then the operator can manually pry open part of the limiting component 200 to completely detach the exposed end of the cable 10 from the insulating protective connector. In some embodiments, the auxiliary sleeve 400 can also be fixed to the second end of the protective sleeve 100 by snap-fit, adhesive, or other methods, not limited to the threaded connection in this embodiment.

[0072] The second end of the auxiliary sleeve 400 is provided with a positioning protrusion 420. When the auxiliary sleeve 400 is threadedly connected to the second end of the protective sleeve 100, the positioning protrusion 420 abuts against the second end of the protective sleeve 100, preventing the auxiliary sleeve 400 from extending excessively into the protective sleeve 100, which would result in an insufficient distance between the closed end of the protective sleeve 100 and the limiting component, thus failing to effectively protect the exposed end of the cable 10. In this embodiment, the positioning protrusion 420 extends in a ring shape along the circumference of the auxiliary sleeve 400.

[0073] Second implementation method

[0074] In this embodiment, the arrangement of the protective sleeve 100, the auxiliary sleeve 400, and the auxiliary withdrawal sleeve 300, as well as the arrangement of the second guide surface 221 and the anti-slip component 230, are exactly the same as in the first embodiment, and will not be repeated here. The difference is that the auxiliary sleeve 400 does not have a clearance opening 410, and the auxiliary withdrawal sleeve 300 does not have a withdrawal protrusion 310 and a compensation groove 320. Specifically, the insulating protective joint also includes an auxiliary sleeve 400, which is disposed at the second end of the protective cylinder 100, and the first end of the auxiliary withdrawal cylinder 300 is inserted into the auxiliary sleeve 400; each of the eight limiting members 200 includes a limiting plate 210 and a limiting part 220, the second end of each of the eight limiting plates 210 is connected to the first end of the auxiliary sleeve 400, the second end extends along direction A, and along direction A, the inner wall of at least one limiting plate 210 is inclined toward the axis of the protective cylinder 100; the limiting part 220 is disposed on the inner wall of the corresponding second end of the limiting plate 210, and pushing the auxiliary withdrawal cylinder 300 along direction A can make the outer wall of the auxiliary withdrawal cylinder 300 abut against the inner wall of the eight limiting plates 210.

[0075] When the auxiliary withdrawal cylinder 300 is inserted into the auxiliary sleeve 400 and the cable 10 is not inserted into the limiting space 201, all eight limiting plates 210 are in their original state; when the exposed end of the cable 10 passes through the auxiliary withdrawal cylinder 300 and is inserted into the limiting space 201, and the second ends of all eight limiting plates 210 are inclined in a direction away from the axis of the protective cylinder 100, and all eight limiting parts 220 abut against the cable 10, so as to limit the exposed end of the cable 10 to the limiting space 201; when it is necessary to... When the exposed end of cable 10 is to be detached from the protective connector, push the auxiliary withdrawal cylinder 300 in direction A. As the auxiliary withdrawal cylinder 300 is continuously pushed, it abuts against the inner wall of each limiting plate 210, causing the second ends of the multiple limiting plates 210 to bend further away from the axis of the protective cylinder 100. This prevents the eight limiting parts 220 from contacting the cable 10, thus facilitating the removal of the exposed end of cable 10 from the limiting space 201. After the exposed end of cable 10 is detached from the protective connector, withdraw the auxiliary withdrawal cylinder 300 in the opposite direction of direction A until all eight limiting plates 210 are back in their original position, so that the insulating protective connector can be used again.

[0076] It is understandable that when the exposed end of the cable 10 passes through the auxiliary withdrawal cylinder 300 and is inserted into the limiting space 201, along direction A, the inner wall of at least one limiting plate 210 is inclined toward the axis of the protective cylinder 100 to be suitable for being opened by the auxiliary withdrawal cylinder 300.

[0077] Third implementation method

[0078] Combination Figure 6As shown, the auxiliary withdrawal cylinder 300 and cable 10 are configured in the same way as in the first embodiment; the configuration of the limiting member 200 is different from both the first and second embodiments. Specifically, the auxiliary sleeve 400 is not provided in the insulating protective joint, and the eight limiting members 200 are all plate-shaped. The first end of each of the eight limiting members 200 is fixedly connected to the inner wall of the protective cylinder 100, and the second end extends towards the axis of the protective cylinder 100. The auxiliary withdrawal cylinder 300 is pushed to abut against the multiple limiting members 200 in the A direction, so that the eight limiting members 200 bend in the A direction.

[0079] The second ends of the eight limiting members 200 cooperate to form a limiting space 201. After the exposed end of the cable 10 passes through the auxiliary withdrawal cylinder 300, the cable 10 is continuously pushed so that the exposed end of the cable 10 is limited in the limiting space 201. When the auxiliary withdrawal cylinder 300 is pushed in direction A, the middle part of each of the eight limiting members 200 abuts against the first end of the auxiliary withdrawal cylinder 300. The auxiliary withdrawal cylinder 300 is continuously pushed so that the second ends of the eight limiting members 200 bend in direction A, thereby expanding the limiting space 201. That is, the second ends of the eight limiting members 200 release the limiting effect on the exposed end of the cable 10, so that the exposed end of the cable 10 can be separated from the limiting components. The exposed end of the cable 10 can be withdrawn from the auxiliary withdrawal cylinder 300, thus completing the disassembly process of the insulation protection joint.

[0080] Because multiple limiting members 200 need to be installed on the inner wall of the protective cylinder 100, and the second ends of the multiple limiting members 200 need to cooperate with each other to form a limiting space 201, the inner diameter of the protective cylinder 100 is larger than the outer diameter of the auxiliary withdrawal cylinder 300. When the exposed end of the cable 10 is limited to the limiting space 201, in order to prevent the auxiliary withdrawal cylinder 300 from shaking radially within the protective cylinder 100, which would cause the cable 10 inserted in the auxiliary withdrawal cylinder 300 to shake and cause the cable 10 to detach from the limiting space 201 on its own, in this embodiment, a positioning ring 110 is fixedly installed on the inner wall of the first end of the protective cylinder 100, and in order to ensure that the first end of the auxiliary withdrawal cylinder 300 can pass through the positioning ring 110 and be inserted into the protective cylinder 100, the inner diameter of the positioning ring 110 is slightly larger than the outer diameter of the auxiliary withdrawal cylinder 300. For example, when the outer diameter of the auxiliary withdrawal cylinder 300 is set to 10cm, the inner diameter of the positioning ring 110 is correspondingly set to 10.2cm.

[0081] In addition, to improve the limiting effect of the limiting space 201 on the exposed end of the cable 10 inserted into the limiting space 201, the second end of each of the eight limiting members 200 is provided with an anti-slip member 230. The specific arrangement of the anti-slip member 230 is the same as in the first embodiment, and will not be repeated here. To improve the convenience of inserting the exposed end of the cable 10 into the limiting space 201, the second end of each of the eight limiting members 200 is provided with a second guide surface 221.

[0082] In the above three embodiments, the second end of the auxiliary withdrawal cylinder 300 is provided with an auxiliary limiting handle 330, which can be limited and abutted against the second end of the protective cylinder 100.

[0083] Specific reference Figure 1 , Figure 3 and Figure 4 As shown, the auxiliary limiting handle 330 is disc-shaped and fixedly mounted on the second end of the auxiliary withdrawal cylinder 300. This configuration serves two purposes: firstly, when the auxiliary withdrawal cylinder 300 is pushed along direction A to abut against multiple limiting members 200, the auxiliary limiting handle 330 can limit the pushing distance of the auxiliary withdrawal cylinder 300 by abutting against the second end of the protective cylinder 100 or the auxiliary sleeve 400. This prevents excessive contact between the auxiliary withdrawal cylinder 300 and the multiple limiting members 200, which could lead to bending and damage. This ensures the insulated protective joint can be reused, reducing operating costs. Secondly, the disc-shaped auxiliary limiting handle 330 improves the ease of operation when moving the auxiliary withdrawal cylinder 300 back and forth in direction A, further enhancing disassembly efficiency.

[0084] In other embodiments, the auxiliary limiting handle 330 may be adapted to be rod-shaped, block-shaped, or plate-shaped depending on the actual situation, which will not be described in detail here.

[0085] In addition, the diameter of the exposed end of the cable 10, the maximum distance between the two oppositely arranged limiting parts 220, the outer diameter of the auxiliary withdrawal cylinder 300, and the inner diameter of the positioning ring 110 mentioned in this embodiment are all examples selected for the purpose of clearly describing the scheme. In actual production, the dimensions of each component are set according to actual needs and are not limited to the examples in this embodiment.

[0086] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
