An insulation stripping tool for flat cables includes a clamping device adapted to be clamped to a flat cable and to provide a linear guide edge for guiding a knife holder to accurately sever the outer insulation sheath of the cable in a transverse direction. Upon removal of the clamping device from the cable, the knife holder is inserted into a chamber contained in the clamping device with the knife edge protruding from the chamber, whereupon a curved side of the flat cable is inserted within first guide grooves contained in the clamping device, and the clamping device is displaced circumferentially of the cable to sever the curved cable side transversely of the cable. The curved cable side is then inserted into a second pair of grooves contained in the clamping device, and the knife holder is displaced longitudinally to sever the insulation sheath longitudinally of the cable.

Insulation stripping tool

Have a pliers housing (2), two clamping jaws (4, 28) which can be pivoted relative to each other to form a mouth (29) of the pliers, in which mouth two stripping members (51, 59) are arranged such that they can be displaced in the longitudinal direction of the mouth by a pull-rod (37), two handles (3, 12), which can be pivoted relative to each other, and a drive device, which is arranged in the pliers housing (2) and can be driven by the pivoting movement of the handles (3, 12) for pivoting the clamping jaws (4, 28) relative to each other and for longitudinal displacement of the pull-rod (37). The drive device has cam discs (18a, 18b) via which both the relative pivoting of the clamping jaws (4, 28) and the longitudinal displacement of the pull-rod (37) can be controlled.

A device for stripping conductor ends contains two stripping devices arranged in a mouth formed by clamping jaws. The two stripping devices can be displaced in a longitudinal direction of the mouth. At least one of the stripping devices includes a stack of laminates which are located side by side. The stack can be moved transversely with respect to the longitudinal direction of the mouth and has cutting edges which penetrate into insulation of a conductor which is held by the clamping jaws when the mouth is closed. A laminate guidance device is matched to the profile of the conductor and controls the laminate transverse movement in a corresponding manner. The laminate guidance device is located on the rear side of the laminate stack.

Tongs for dressing conductor ends have two handles (3, 11) which can move relative to one another, at least two dressing stations (4, 8), and a drive device (10, 12, 20), via which the dressing stations can be driven during operation of the handles. At least one (18, 19) of the dressing stations (4, 8; 18, 19) can be coupled to the drive device (10, 12, 20) with the aid of the conductor end (28) which is to be dressed. The dressing station which can be coupled to the drive device is thus driven only when this is also actually required.

Core end sleeves (22) are linked to one another in the form of a belt and in each case have a metal sleeve (70) in the front region and a plastic sleeve (71), which partially engages over the metal sleeve (70), in the rear region, via which the core end sleeves are connected to one another. The plastic sleeves are in each case provided on their rear end with a projection (72) which points to the rear and rests on an outer side of the belt. The height, running at right angles to the plane of the belt, of the projection (72) is independent of the diameter of the plastic sleeves (71). Core end sleeves (22) for different conductor cross-sections can thus be transported using one and the same core end sleeve guide track (63) which has a guide groove (67) on its one side wall (65) for the projections (72).

Pliers for dressing conductor ends have two handles (3, 11) which can move relative to one another, a plurality of dressing stations for the conductor ends, and a drive device (21) via which the dressing stations can be driven during operation of the handles (3, 11). One of the dressing stations is constructed as a crimping drum (18) which can be displaced axially and is supported such that it can rotate and be coupled to the drive device (21) in the axially displaced position over only one dressing process. In this position, the station can be locked via a flange (52) which projects radially from it. This flange (52) extends over the overall circumference of the crimping drum (18) and has at least one recess (51). A locking tab (50a), which is arranged in a fixed position on the body (2) of the pliers and is radially opposite the flange (52), engages, in the undisplaced axial position of the crimping drum (18), into the recess (51), to be precise up to a point close to the outer surface of the crimping drum (18) while, in the axially displaced and rotated position of the crimping drum (18), the locking tab (50a) comes to rest above the outer surface of the crimping drum and engages behind the flange (52). Locking of the crimping drum (18) both in the rotational direction and in the axial displacement direction is thus possible by the locking tab (50a).

Connectors with a barrel-shaped ferrule are produced from an intermediate which is embodied by metallic strip consisting of a plurality of connector blanks linked together by interconnecting means, each blank comprising a first ferrule-forming part and a second tongue-forming part, and including a first zone which comprises all the first parts, and an adjacent second zone which comprises all the second parts and all the interconnecting means, the side edges of neighbouring first parts in the strip being separated by free interspaces and a continuous layer or cover of insulating material being adhesively applied on the first zone, on at least one obverse surface of the strip, so as to extend beyond a terminal edge of the first part, the said layer being within said interspaces cut through and bent so as to form at least one flap sufficiently large to adhere when folded back.

Methods of producing intermediates for connectors with insulated ferrules

A contact element such as an end-sleeve or a cable shoe, having a connecting portion and a contact portion, is produced from an originally plane blank which has a substantially rectangular first part, which in the finished product defines said connecting portion, and a second part, which in the finished product defines said contact portion. A plurality of such blanks is joined into a metallic punching band with an obverse face and a reverse face and comprising a first zone with all the first parts of the blanks, and a second zone with all the second parts of blanks. On at least the obverse face of the first zone is an insulating cover or coating applied before the individual blanks are removed from the punching band, so that the contact elements having a metallic connection portion with an insulating layer are obtained.
