Detailed ways

The utility model provides a composite tapered cable connector, which solves the problem of low reliability of the cable system of the existing technical solution, achieves a more stable cable connection effect, and helps to obtain stronger load-bearing capacity. The cable R to which this solution is applicable particularly includes (but is not limited to) fiber ropes. The cable R includes a plurality of parallel wires R1. The wires R1 constitute the core of the cable R, and the core is wrapped with a cable sheath R2.

Please refer to Figures 1 and 2. A composite tapered cable connector according to an embodiment of the present invention includes a connector body 1 in the shape of a tapered sleeve. A composite tapered cable connector is matchedly provided in the connector body 1. Conical structure, the composite conical structure includes an intermediate cone sleeve 2 in the shape of a cone sleeve, and a cone nail 3 is provided in the intermediate cone sleeve 2. Preferably, the outer diameter of the end of the awl nail 3 gradually decreases to form a tip 31, which serves to facilitate the spread of the wire R1 and provide a smooth transition to avoid stress concentration caused by the wire R1 contacting edges with smaller angles. One end of the connector body 1 is connected with the cable R, and the other end of the connector body 1 is provided with a terminal 4 . The connector body 1 and/or the terminal 4 have a connecting portion 41 .

The wire R1 of the cable R is spread out at the composite tapered structure and clamped between the taper nail 3 and the intermediate taper sleeve 2. The wire R1 continues to extend from the side near the end 4 and is folded outward. It is arranged and clamped between the intermediate taper sleeve 2 and the connector body 1. A cable sheath R2 is provided outside the portion of the wire R1 that is not spread out. This creates a double clamping force on the wire R1 to ensure the reliability of the connection, and eliminates the need to use cement, thereby achieving repeatable installation and removal.

More specifically, the inner diameter of the connector body 1, the inner and outer diameters of the intermediate taper sleeve 2, and the outer diameter of the taper nail 3 are all along the direction from the end 4 to the cable R (from right to left in Figure 1 direction) gradually decreases, thus forming conical structures nested in sequence. When the tensile force borne by the cable R increases, the clamping force between the conical structures also increases; taking Figure 1 as an example, the cable R direction Pulling to the left, the middle taper sleeve 2 tends to move to the left, and the inner diameter of the left side of the connector body 1 is smaller. Therefore, the greater the pulling force, the tighter the wire R1 is clamped, preventing the movement of the cable R and achieving a stable connection. It can be understood that the composite tapered structure of the present invention is not limited to this. For example, on the basis of the above in Figure 1, the inclination directions of the inner surface of the adjacent intermediate tapered sleeve 2 and the outer surface of the tapered nail 3 are changed to opposite directions. direction (the diameter gradually increases in the direction from end 4 to cable R), the double clamping force effect can also be achieved.

In some feasible embodiments, the end of the wire R1 is clamped between the intermediate cone sleeve 2 and the connector body 1; preferably, the end of the wire R1 protrudes from an end of the intermediate cone sleeve 2 away from the end 4. side (left side in Figure 1). Extend the end of the wire R1 from the front to the clamping position between the intermediate taper sleeve 2 and the connector body 1 to ensure that the wire R1 has a sufficiently long clamped length, which helps to improve the positioning and connection effect. In actual use, in order to facilitate installation, usually after the wire R1 is folded outward, structures such as films and tapes are wrapped around the middle cone sleeve 2 and the outside of the wire R1 for binding, or they can be inserted into the In front of the bushing 5, inject cement from the inlet of the cable R on the left side in Figure 1 to fill the interior of the cavity of the connector body 1.

At the position where the cable R is exposed from the composite tapered cable connector (the left end of the connector body 1 in Figure 1), a bushing 5 is provided outside the cable sheath R2 of the cable R, and the bushing 5 is connected to the connector body Within 1. The bushing 5 is a cylindrical sleeve. For example, the bushing 5 is connected to the cable R and the connector body 1 by a sealing interference fit or by adhesive bonding. The bushing 5 has three functions: first, the bushing 5 can position and protect the access end of the cable R; second, the bushing 5 can achieve waterproof and dustproof sealing there; third, during actual use, , the bushing 5 can be designed in multiple specifications with different inner diameters. For example, the outer diameters of the various bushings 5 all match the connector body 1, and the inner diameters match the outer diameters of the cables R of various specifications. Therefore, the same size The connector body 1 can be adapted to two or more cables R with different diameters by replacing the bushings 5 of different specifications. Therefore, the composite tapered cable connector of this solution has strong compatibility, high flexibility in use, and helps to reduce design, production and use costs. In addition, according to needs, the taper nail 3 and the intermediate taper sleeve 2 can also be designed and produced in different specifications for adaptation.

In the embodiment shown in FIG. 1 , the terminal 4 is in the shape of a cover with one end open, that is, the terminal 4 has a cylindrical side wall on one side, and the terminal 4 is covered and disposed outside the connector body 1 . The cap-shaped inner surface of the terminal head 4 has internal threads, and the outer surface of the connector body 1 has matching external threads. The terminal head 4 and the connector body 1 are threadedly connected. It can withstand large axial tension and is detachable. It is conceivable that in addition to threaded connection, the terminal 4 and the connector body 1 can also be connected by other methods such as bonding, screw connection, positioning pin connection, etc. There is a sealing ring groove on the outside of the connector body 1 and a sealing ring 6 is set therein. When the end head 4 and the connector body 1 are installed, the sealing ring 6 is located at the opening edge of the end head 4 and forms a seal between the end head 4 and the connector body 1 .

In the embodiment shown in Figure 4, the end 4 is in the shape of a cylindrical plug. The outer side of the end 4 is provided with external threads. The inner side of the connector body 1 is provided with matching internal threads. The end 4 is screwed through the plug. is installed in the connector body 1. There is a sealing ring groove outside the end 4 and a sealing ring 6 is set therein. When the end head 4 and the connector body 1 are installed, the sealing ring 6 is located at the edge of the connector body 1 and forms a seal between the connector body 1 and the end head 4 .

The sealing ring 6 using the above two settings not only provides waterproof and dustproof sealing protection effect, but also provides a visual reminder whether it has been installed in place, thereby making it easier for installers and maintenance personnel to visually and conveniently check the installation and connection conditions, and avoid possible Problems that are difficult to detect due to substandard installation can further improve the fault tolerance rate and ensure the reliability of cable connections.

Please refer to Figure 1 again. The ends of the taper nail 3 and the intermediate taper sleeve 2 are basically flat. The end 4 directly or indirectly conflicts with the taper nail 3 and/or the intermediate taper sleeve 2, thereby providing a tightening force during installation. , ensure that wire R1 is clamped at the inner and outer clamping positions. It is conceivable that, for example, in a solution in which the taper nail 3, the intermediate taper sleeve 2, the connector body 1 and/or the wire R1 are directly bonded and fixed, there is no need for the end 4 to be pressed against. Preferably, a gasket 7 is provided between the end head 4 and the taper nail 3 and/or the intermediate taper sleeve 2. The gasket 7 is made of stainless steel or plastic, for example, and has a small friction coefficient, which helps to reduce the end friction. The friction between the head 4 and the taper nail 3 and/or the intermediate taper sleeve 2 facilitates the installation of the end head 4 and also helps to ensure the tightening effect of the end head 4.

In the embodiment shown in FIG. 3 , the taper nail 3 and the end 4 are in conflict with or connected through the top post 8 . The gasket 7 has a through hole and is set outside the top post 8 . More specifically, the top post 8 is, for example, a stud, a bolt, or an unthreaded column, block, etc. The top post 8 is threadedly connected to or directly penetrates the mounting hole opened in the middle of the end head 4, and the other end of the top post 8 is connected with a taper nail. 3 contradict or connect with each other. Furthermore, the end of the taper nail 3 can optionally have a positioning groove or be connected to the top post 8 in other ways, so as to achieve auxiliary positioning of the taper nail 3 while tightening, ensuring that the taper nail 3, the end 4 and the connection The axes of the device body 1 are basically coincident, which helps to improve the uniformity of the force on the wire R1.

As shown in the embodiment shown in FIG. 4 , the end 4 is a plug-shaped structure in the connector body 1 , and the top post 8 is a protrusion integrally provided on the end 4 so as to pass through the through hole on the gasket 7 , directly conflicting with the taper nail 3. It is conceivable that for this structure using the plug-shaped end 4, the top post 8 may not be provided, or a separate top post 8 may be provided, etc.

As shown in Figures 1 and 2, a tool hole 42 is circumferentially provided on the outer surface of the end head 4, and as shown in Figures 4 and 5, a flat surface is provided on the cylindrical outside of the connector body 1 to facilitate the use of tools. Carry out wrenching, complete installation or removal.

As shown in FIGS. 1 and 2 , the connecting portion 41 is provided on the side of the end 4 away from the cable R. The connecting portion 41 has a connecting hole for connecting other components such as pins or shackles. The connecting part 41 is, for example, two ear plates arranged side by side and opposite to each other, and is processed into a cylindrical shape, for example; as shown in FIG. 5 , it is processed into a spherical shape; or the connecting part 41 can optionally have only one ear plate. , or a connecting ring, etc., any structure that can realize the connection can be used.

In some specific embodiments, the connector body 1 and the terminal 4 can be manufactured using a variety of processes and materials, such as hot-dip galvanized carbon steel, stainless steel, aluminum alloy, copper alloy, plastic, composite materials, etc. For a cable connector with a load of 3 to 10.5 tons, for example, in the structure shown in Figure 1, the angle of the generatrix of the conical surface of the connector body 1, the intermediate taper sleeve 2 and the taper nail 3 relative to the horizontal direction is 1.5 degrees. From left to right, the total length of the structure (the length from left to right, excluding the R part of the cable outside the left end) is about 130mm to 175mm. The structure is compact and easy to use in various fields.

Taking the embodiment shown in Figure 1 as an example, a process for installing and using the composite tapered cable connector of the present invention is as follows. First, insert the cable R (with a bushing 5 on the outside) from left to right into the connector body 1 (with a sealing ring 6 on the outside) and the middle taper sleeve 2. Peel off the cable sheath R2 at the end of the cable R and remove the internal wires. R1 is spread out, and then the taper nail 3 is inserted into the middle taper sleeve 2 from right to left, and placed in the middle of the wire R1, so that the wire R1 is basically evenly distributed outside the taper nail 3, and the taper nail 3 is initially compacted. inside the middle cone sleeve 2, and then fold all the wires R1 outwards and distribute them basically evenly outside the middle cone sleeve 2; at this time, if the end of the wire R1 is not enough to protrude from the left end of the middle cone sleeve 2, then The structure can be disassembled again, move the cable R to the right, increase the length of the wire R1 and reinstall it; use plastic film to wrap around the middle cone sleeve 2 and the wire R1, and pre-fix the wire R1 to the middle cone sleeve 2. outside; then move the cable R, the middle taper sleeve 2 and the taper nail 3 as a whole to the left, put the middle taper sleeve 2 and the taper nail 3 into the connector body 1; screw in the installation cap-shaped end 4 (with an internal Gasket 7), when the end 4 is screwed into the connector body 1 until it is close to the fastening position, the gasket 7 inside the end 4 is first pressed against the right ends of the taper nail 3 and the middle taper sleeve 2, and then pushed forward. At this time, the taper nail 3 and the middle taper sleeve 2 of the wire R1 have been clamped to the fully tightened position, and the cylindrical edge of the left end of the end 4 has moved to a position that completely covers the sealing ring 6; when the installation is completed, the seal The ring 6 should be completely hidden between the end 4 and the connector body 1 (the length dimensions of each component are designed like this), so that you can judge whether it is installed in place; finally, insert the bushing 5 into the connector body 1. A watertight seal is formed between the cable R and the connector body 1 .

During the installation and disassembly process, special disassembly tools can be used: for example, when screwing the installation end 4, a wrench-shaped tool is used. The positioning end of the tool has an inwardly protruding positioning post, and the positioning post is Insert the tool hole 42 and tighten; for example, during disassembly, after removing the bushings 5 and ends 4 at both ends of the connector body 1, the intermediate taper sleeve 2 may still be tightly attached to the connector body 1 and cannot be separated. At this time, the cylindrical disassembly tool 9 (for example, as shown in Figure 5) can be inserted from the gap position between the connector body 1 and the cable R where the bushing 5 is originally located, and the intermediate taper sleeve 2 can be pushed outward.
