Definitions

• the present invention relates to a device for constituting a fastening at the end of a plastic envelope cable (electrical or telephone type).
• the purpose of this fastener is to allow a solid connection between a cable and a pulling pin located in a conduit or sheath.
• the cable pulling attachment is traditional - the ent made with the wires of the cable, released after stripping and then wrapped with adhesive tape to form a loop then connected to the pulling pin.
• the invention aims to overcome these drawbacks by proposing a fastening means composed of a metal socket to be crimped in the form of a cylindrical tube whose inner diameter corresponds to the diameter of the cable and in which the end of the cable is slid in order to crimp.
• This socket then receives a specific crimp to make it integral with the cable, creating an effective attachment means requiring neither stripping nor the use of adhesive tape.
• the invention thus aims to provide a crimping socket with which the production of an attachment means on the cable becomes a simple and rapid operation using manual pliers provided with a cutting crimping punch. Characteristics and advantages will appear on reading the following description which refers to the appended figures in which:
• FIG. 1 is a schematic view in partial section of the socket according to the invention.
• FIG. 2 and FIG. 3 are views in partial section respectively illustrating a second and a third variant of the invention.
• FIG. 4 is a schematic view in partial section of the socket once crimped according to the invention.
• FIG. 5 is a schematic view of a crimping tool relating to the invention.
• FIG. 6 is a schematic view of the punch penetrating the socket according to the invention.
• the invention relates to a sleeve (1), slipped on a cable (4), to which a partial tear is applied using pliers (5) provided with a punch (6) causing a projection (3) which penetrates into the material of the cable.
• This projection (3) facing forward and inclined towards the heart of the cable acts as a claw planted in the material, retaining the cable in the socket (1).
• two or more projections (3) will be applied, thus giving a very resistant connection in traction.
• the invention is also characterized by a fixing means (2) having the role of connecting the pulling pin to the socket (1).
• the sleeve is extended by a fixing means (2) preferably consisting of a thread or a threaded end or a simple perpendicular drilling.
• the invention is also characterized by a sleeve (1) whose thickness of the cylindrical envelope accommodating the cable is such that it can be perforated easily.
• the device according to the invention is particularly easy to implement thanks to a simple clamp (5) provided with a punch (6) which penetrates the sleeve to form a projection (3).
• the punch (6) has a conical shape partially cut along its vertical axis, forming a flat with cutting edges.
• the invention is also characterized by a socket (1) whose outside diameter differs very little from the diameter of the cable (4), thus optimizing its capacity for passage through a conduit.
• the socket according to the invention also advantageously comprises a circular chamfer at its end (tapped side), thus avoiding the risk of being caught in the duct or sheath.
• the invention also aims to propose a socket of simple and inexpensive design for easy use which, once used, will be eliminated by cutting the cable.
• the invention also aims to propose a means of crimping the sleeve characterized by a manual pliers of simple, reliable design, easy to use and usable in any place.
