Description

Technical Field

[0001] This utility model belongs to the field of cable joint technology, and specifically relates to a cable joint that is easy to install. Background Technology

[0002] As a key component connecting ropes to ropes or to a fixed end, the installation efficiency and connection reliability of rope joints directly affect the overall operational safety and ease of use. Currently, commonly used rope joints in the industry mainly include plug-in type, rope clamp fastening type, compression sleeve type, and fusion splicing type structures.

[0003] Plug-in connectors form a connection by interlacing multiple strands of rope, requiring multiple steps such as untangling, interlacing, and locking. This relies heavily on the operator's professional skills, and installation typically takes more than 10 minutes, making rapid connection difficult. Rope clamp or compression fitting connectors require auxiliary tools such as wrenches and hydraulic equipment to tighten bolts or press metal sleeves, significantly reducing installation efficiency in emergency scenarios where specialized tools are unavailable. While fusion-welded connectors offer high connection strength, they require high-temperature heating to melt the rope ends and then cooling them to form the final shape. This is not only complex to operate but also prone to deterioration of the rope material due to improper temperature control, and cannot be adapted to scenarios requiring frequent disassembly and reassembly.

[0004] Existing cable joint limiting structure designs generally suffer from low contact efficiency. The contact form between the limiting component and the cable is mostly point contact or line contact, resulting in insufficient constraint strength of the limiting area on the cable. When the joint is subjected to axial tensile force or radial impact load, relative slippage is likely to occur between the cable and the limiting component due to contact stress concentration. Utility Model Content

[0005] The purpose of this utility model is to provide a cable connector that is easy to install, so as to solve the problem of low contact efficiency that is commonly found in the limiting structure design of cable connectors mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easy-to-install cable connector includes: a connector body, and further includes:

[0008] There are two wire-passing holes, one at each end of the connector body, and the two wire-passing holes are symmetrically distributed.

[0009] The threading hole is a fold-back through hole, with its inlet and outlet located on the same end face of the connector body, which is suitable for cable threading and forms a bending constraint section.

[0010] Two limiting mechanisms are provided, one for each of the wire holes;

[0011] The limiting mechanism includes a first limiting head and a second limiting head, which are used to fit against the surface of the rope after it is inserted to form a limit and prevent the rope from detaching.

[0012] Preferably, grooves are provided at both ends of the connector body, and wire holes are respectively provided on the inner wall of the grooves.

[0013] Preferably, the limiting mechanism further includes:

[0014] The first through hole is formed on the side wall of the groove, and the first limiting head is connected inside the first through hole;

[0015] The second through hole is opened on the inner wall of the wire hole, and the second limiting head is connected inside the second through hole.

[0016] Preferably, the limiting mechanism further includes:

[0017] A control sleeve is fitted onto the connector body, and the inner wall of the control sleeve has a connecting groove.

[0018] The first control head is installed on the inner wall of the connecting groove, and one end of the first control head is in contact with the first limit head;

[0019] The second control head is installed on the inner wall of the connecting groove, and one end of the second control head is in contact with the second limit head.

[0020] Preferably, one end of the first limiting head and the second limiting head are provided with an inclined surface, and the first control head and the second control head are respectively attached to the two inclined surfaces.

[0021] Preferably, the inner walls of the first through hole and the second through hole are provided with moving grooves, and a moving block is installed on one side of the first limiting head and the second limiting head, and the moving block is connected to the moving groove.

[0022] Preferably, an elastic element is installed on the inner wall of the moving groove, and one end of the elastic element is connected to the moving block.

[0023] Preferably, the control sleeve includes:

[0024] A gasket is installed at one end of the control sleeve, and the gasket is fitted onto the connector body;

[0025] The adjusting nut is installed on the washer, and the adjusting nut is connected to the connector body by threads.

[0026] Preferably, one end of both the first limiting head and the second limiting head is coated with an anti-slip layer.

[0027] Preferably, the inside of the wire hole has an elliptical or circular cross-section.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] This invention utilizes a folding-through threading hole to create a bent constraint section for the rope, using the friction generated by the bend to initially limit rope slippage. The first and second limiting heads, under the coordinated action of the control sleeve, control head, and elastic element, exert a stable clamping force on the rope. This multi-layered constraint enhances the constraint strength of the limiting area on the rope, effectively resisting axial tensile force and radial impact loads. The first and second limiting heads conform to the rope surface at different angles, increasing the contact area between the limiting components and the rope, thus improving contact efficiency. Due to the increased contact area, enhanced constraint strength, and tight fit between the limiting heads and the rope, relative slippage between the rope and the limiting components under force is effectively suppressed, preventing the rope from detaching from the limiting area and improving the safety and reliability of the rope joint.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-5A cable connector for easy installation includes: a connector body 100, and two through holes 102, respectively located at both ends of the connector body 100, with the two through holes 102 symmetrically distributed; the through holes 102 are fold-back through holes, with their inlet and outlet located on the same end face of the connector body 100, adapted for cable insertion and forming a bending constraint section; and two limiting mechanisms, corresponding to each other within the through holes 102; the limiting mechanisms include a first limiting head 103 and a second limiting head 104, used to conform to the surface of the cable after it is inserted, forming a limit to prevent the cable from detaching.

[0038] By setting two symmetrically distributed folding through holes as wire-passing holes 102 at both ends of the connector body 100, the inlet and outlet of the wire-passing holes 102 are located on the same end face of the connector body 100. At the same time, a limiting mechanism including a first limiting head 103 and a second limiting head 104 is set in each wire-passing hole 102, forming a combination structure of bending constraint and fitting limit after the rope is passed through. With the path constraint of the folding channel and the fitting effect of the double limiting heads, the rapid passing through and stable limiting of the rope can be achieved.

[0039] The folding-through hole 102 causes the rope to bend naturally after being threaded through, and the friction generated by the bend initially restricts the rope from sliding. The first limiting head 103 and the second limiting head 104 fit against the surface of the rope from different angles. By increasing the contact area, the force is dispersed, and the limiting effect is further enhanced. The combination of the two simplifies the installation process and improves the stability of the connection through multiple constraints, thus meeting the dual requirements of rapid installation and reliable limiting.

[0040] The design of the common inlet and outlet of the folding-through hole 102 eliminates the complicated operation of threading the cable through different ports at both ends, allowing the cable to be threaded from the same end, which significantly improves the installation speed. The first limiting head 103 and the second limiting head 104 of the limiting mechanism are in contact with the surface of the cable, which increases the contact area between the limiting part and the cable, improves the contact efficiency, and effectively prevents the cable from detaching from the limiting area after being subjected to force.

[0041] Both ends of the connector body 100 are provided with grooves 101, and wire holes 102 are respectively provided on the inner wall of the grooves 101.

[0042] The limiting mechanism further includes: a first through hole 105, formed on the side wall of the groove 101, with the first limiting head 103 connected inside the first through hole 105; a second through hole 106, formed on the inner wall of the wire hole 102, with the second limiting head 104 connected inside the second through hole 106; a control sleeve 200, fitted onto the connector body 100, with a connecting groove 203 formed on the inner wall of the control sleeve 200; a first control head 204, installed on the inner wall of the connecting groove 203, with one end of the first control head 204 in contact with the first limiting head 103; and a second control head 205, installed on the inner wall of the connecting groove 203, with one end of the second control head 205 in contact with the second limiting head 104.

[0043] By opening grooves 101 at both ends of the connector body 100, and setting the threading hole 102 on the inner wall of the groove 101, the cable can form a preliminary positioning space by relying on the groove 101 when it is threaded through; the first through hole 105 and the second through hole 106 in the limiting mechanism provide mounting carriers for the first limiting head 103 and the second limiting head 104 respectively; the control sleeve 200 drives the first control head 204 and the second control head 205 through the inner wall connecting groove 203, which respectively act on the first limiting head 103 and the second limiting head 104, forming a linkage limiting structure that can be operated by the control sleeve 200.

[0044] The groove 101 provides a guiding space for the cable to pass through the threading hole 102, reducing unnecessary friction between the cable and the connector body 100 during the threading process and further improving installation convenience. The control sleeve 200 drives the first and second control heads 205 to act on the corresponding limit heads, which can realize synchronous linkage control of the limit mechanism. This ensures the consistency of the first and second limit heads 104 with the cable, and allows for quick adjustment of the limit force by operating the control sleeve 200. While improving contact efficiency, it also prevents the cable from detaching due to the loosening of a single limit head, thus enhancing the stability of the connector under dynamic stress.

[0045] One end of the first limiting head 103 and the second limiting head 104 is provided with an inclined surface, and the first control head 204 and the second control head 205 are respectively attached to the two inclined surfaces.

[0046] The inclined plane structure utilizes the principle of labor saving by decomposing the axial force applied by the control sleeve 200 into a radial force that pushes the limit head to move in the direction of the rope. This reduces the force required to operate the control sleeve 200 and allows for precise control of the displacement of the limit head through the design of the inclined plane angle, ensuring that the clamping force of the two limit heads on the rope is uniform and controllable.

[0047] The inclined surface concentrates the force exerted by the first control head 204 and the second control head 205 on the limiting head, reducing losses during force transmission and enabling the operation of the control sleeve 200 to be quickly converted into the clamping force of the limiting head on the cable, thus improving the sensitivity of the limit adjustment. At the same time, the inclined surface ensures the contact stability between the control head and the limiting head, avoiding operational lag caused by relative sliding, and further enhancing the tightness of the fit between the limiting head and the cable, so that the tendency of the cable to detach can be counteracted more promptly when under force.

[0048] The inner walls of the first through hole 105 and the second through hole 106 are provided with moving grooves. The first limiting head 103 and the second limiting head 104 are each equipped with a moving block 107 on one side. The moving block 107 is connected to the moving groove. The inner wall of the moving groove is equipped with an elastic element 108. One end of the elastic element 108 is connected to the moving block 107.

[0049] The moving groove and the moving block 107 constitute a sliding guide mechanism. The matching accuracy of the two ensures the linearity of the displacement of the limit head, eliminates the deflection deformation caused by radial force, and ensures that the force transmission efficiency of the inclined plane transmission is not affected. The elastic element 108 adopts elastic elements such as springs or elastic blocks. Its deformation energy storage and release characteristics realize the automatic reset function of the limit head. Moreover, through the continuous action of elastic force, the limit head and the rope are more tightly attached, and a stable limiting effect can be maintained even when subjected to force fluctuations.

[0050] The cooperation between the moving groove and the moving block 107 restricts the movement trajectory of the limit head, preventing it from deviating or getting stuck when subjected to force, ensuring that the limit head always fits the rope precisely in the radial direction, and improving the reliability of the limit mechanism; the elastic element 108 can drive the limit head to automatically reset when the control sleeve 200 is released.

[0051] The control sleeve 200 includes: a gasket 201, which is installed at one end of the control sleeve 200 and is sleeved on the connector body 100; and an adjusting nut 202, which is installed on the gasket 201 and is threadedly connected to the connector body 100.

[0052] The threaded engagement between the adjusting nut 202 and the connector body 100 utilizes the self-locking characteristic of the screw drive to convert circumferential motion into axial linear motion, achieving precise locking of the control sleeve 200 position and preventing the control sleeve 200 from loosening due to vibration or other factors. The gasket 201 is made of elastic or rigid material, which reduces local pressure by increasing the contact area. This protects the contact surface between the control sleeve 200 and the adjusting nut 202, and can also compensate for assembly errors through its own deformation, ensuring the uniformity of force transmission.

[0053] Both the first limiting head 103 and the second limiting head 104 have an anti-slip layer coated at one end. The anti-slip layer enhances the friction between the limiting head and the surface of the rope. The threading holes 102 with different cross-sections can be adapted to ropes of different diameters and shapes. In conjunction with existing structures such as the adjusting nut 202, washer 201, and moving groove, the limiting mechanism can more tightly constrain the rope and improve the compatibility of the joint with various ropes.

[0054] The wire hole 102 has an elliptical or circular cross-section inside. The cross-sectional shape of the wire hole 102 is designed according to the geometry of the rope. The elliptical cross-section can be adapted to flat ropes of different widths by adjusting the dimensions of the major and minor axes, while the circular cross-section forms a surface contact with the circular rope. Both can improve the fit between the rope and the hole wall by optimizing the contact shape, thereby reducing the resistance during wire threading.

[0055] Working principle and usage process of this utility model:

[0056] During installation, first align the end of the cable to be connected with the inlet of the threading hole 102 in the groove 101 at one end of the connector body 100. Using the guiding effect of the groove 101, thread the cable through the inlet into the fold-back through hole, bending it along the channel and exiting from the outlet at the same end, forming a bending constraint section. The friction generated by the bending initially restricts cable slippage. Then, rotate the adjusting nut 202 on the control sleeve 200. Since the adjusting nut 202 is threadedly connected to the connector body 100, its rotation causes the control sleeve 200 to move axially. The first control head 204 and the second control head 204 in the connecting groove 203 on the inner wall of the control sleeve 200... The control head 205 moves along with the control head, and comes into contact with the inclined surfaces at the ends of the first limiting head 103 and the second limiting head 104 respectively. Through the force transmission of the inclined surfaces, the first limiting head 103 is pushed along the moving groove in the first through hole 105 and the second limiting head 104 is pushed along the moving groove in the second through hole 106 towards the rope. The moving block 107 slides in the moving groove to provide guidance for the limiting heads until the ends of the two limiting heads coated with anti-slip layer are tightly attached to the surface of the rope. At this time, the elastic element 108 is compressed and stores elastic force. The self-locking characteristic of the adjusting nut 202 is used to maintain the position of the control sleeve 200, thereby achieving stable limiting of the rope.

[0057] During disassembly, rotate the adjusting nut 202 in the opposite direction to move the control sleeve 200 in the opposite direction along the axial direction. The force exerted by the first control head 204 and the second control head 205 on the inclined surface of the limit head is weakened. The elastic element 108 in the compressed state releases its elastic force, pushing the first limit head 103 and the second limit head 104 to reset along the moving groove through the moving block 107, disengaging from the rope and releasing the limit constraint. Finally, the rope and cable can be pulled out from the outlet and inlet of the threading hole 102 in sequence to complete the disassembly.
