In the preferred embodiment, the wire clamping component 2 is wedge-shaped, and the wedge-shaped wire clamping component 2 is provided with two inclined side surfaces which are intersected to form an acute angle at the access end 11, and the two inclined side surfaces are connected to form a circular arc shape at the connection end 12; two end surfaces adjacent to the inclined side surface in the wedge shape are basically parallel; the clamping surface 13 on the inside of the connector body 1 is also in the form of a mating wedge. The rope body R completely surrounds the wire clamping part 2 and clings to two inclined side surfaces of the wire clamping part 2, and the casting agent channels 21 penetrate through the two inclined side surfaces of the wire clamping part 2, namely, each casting agent channel 21 is T-shaped in the whole view, so that casting agent can be applied to both sides. It is conceivable that in other embodiments, the clamping surface 13 and the wire clamping member 2 are in a generalized conical shape, i.e. a shape similar to a cone or a pyramid or a combination of both, in any case in that the side of the access end 11 is narrow/thin and the side of the connection end 12 is wide/thick, so that the above-mentioned pulling-over-tightening effect is achieved by means of a slope, and various specific shapes can be formed by adjusting on the basis of the inventive concept.

As shown in fig. 2 and 3, the wire clamping member 2 is preferably provided with a boss 24 on a side surface adjacent to the inclined side surface, the inner side surface of the connector body 1 is provided with a rail groove 18, and the boss 24 is matingly connected with the rail groove 18.

A specific seal cover 5 is shown in fig. 5, which encloses the end of the wire clamping member 2 and the cable R thereon and is sealingly connected to the connector body 1 by, for example, adhesive means.

The cable connector of the utility model can be applied to cable bodies R of various types and materials, for example, in the embodiment shown in fig. 1, the cable bodies R are straight-wire fiber cables (such as special fiber cables of aramid fibers and the like), the outer sides of the straight-wire fiber cables are cable jackets R2, the inner sides of the straight-wire fiber cables are cable cores R1, the cable cores R1 are formed by a large number of straight-wire fibers, the parts contacted with the wire clamping components 2 are cable cores R1 with the cable jackets R2 removed, and after the casting agent is installed and injected, the casting agent directly contacts with the cable cores R1 for solidification. Alternatively, as in the embodiment of fig. 6, the rope body R is a braided rope (e.g., a conventional multi-strand braided rope or a specialty fiber rope, etc.), which is typically unsheathed. For another example, the rope R may be a wire rope or the like.

In order to further embody the structure and beneficial technical effects of the scheme of the utility model, the following installation steps are given as an example of a preferred embodiment.

The solution with the connector cavity 17 shown in fig. 1 may be used as a "partial casting cement method", comprising in particular the following steps.

2. The whole piece of the cable body R and the wire clamping member 2 is pulled into the cavity of the connector body 1. The components should be fully covered with the sealing cap 5 when in place for product design purposes. Cement is injected through the casting agent injection hole 14 in the connector body 1, and the cement flows to portions on the rope R through a groove structure such as the casting agent passage 21.

3. Erecting the connector body 1 (with the access end 11 up), injecting cement from the port of the access end 11 into the connector cavity 17 and covering the cement over the tie 3 position; while the cement is uncured, the cable R is straightened, plugged into the bushing (the access end seal 4) and the connector body 1 is kept in the upright position for about 30 minutes (typically the time required for the cement to reach 75% cure).

More preferably, a "full line casting cement process" may be employed which is suitable for extremely humid or environmental pollution conditions, including in particular the following steps.

1. The rope body R (the braided rope or the straight-wire fiber cable after the cable sheath R2 is removed) is tightly wound around the wire clamping member 2 for one turn, and the end of the rope body R is tied with the tie 3. The surface of the cable body R is coated with cement, and the cable body R and the wire clamping member 2 are pulled into the connector body 1 while the cement is uncured.
