Abstract:
A cable tie includes an elongate generally planar strap and a head. The head of the cable tie includes an aperture therethrough for insertably accommodating the strap. The head of the cable tie also includes a barb embedding surface adjacent the aperture through the head. A metallic locking barb is embedded in the embedding surface in a direction substantially parallel to the aperture in the head. The metallic locking barb is bent to form an obtuse angle so that the metallic locking barb extends into the aperture in the head to permit movement of the strap in an insertion direction and to prevent substantial movement of the strap in a withdrawal direction.
Abstract:
A low thread force two piece cable tie includes a strap, a locking head forming a strap accepting channel, a metal barb positioned within the channel and mounted to the locking head, and a cored out pocket disposed adjacent the metal barb at the entrance to the strap accepting channel. The cored out pocket allows for a slight rotation of the metal barb during insertion of the tip of the strap which enhances the threadability of the cable tie.
Abstract:
The head portion of a bundling strap is provided with severing means encompassing a strap body receiving aperture extending transversely through the head portion, said severing means having a sharpened blade partially restricting the head portion aperture opening to enable the excess portion of the strap body extending beyond the head portion to be severed from the remainder thereof by urging the strap body against the sharpened blade. The sharpened blade may comprise either a continuous edge or selected elements of predetermined length extending inwardly from the periphery of the strap head portion and located preferably generally adjacent or coincident with one face of the head portion to permit the strap body portion to be severed at a position generally flush with the adjacent face of the head portion. An obliquely angled, inwardly protruding leg portion extending from the inner surface of the severing means may be provided to lockingly engage the strap body portion within the apertured head portion of the bundling strap.
Abstract:
A bundling tie for use in looping about a plurality or bundle of elements, such as wires, tubes or cables, and to be drawn taunt about the bundle for mounting of the elements in bundle form on a support, such as for instance on a circuit board or harness board assembly, and comprising a buckle head having an aperture therethrough and a separate insert pawl mounted in the aperture of the head in generally floatable condition, adapted for locking coaction with a strap portion that is disposed in looped condition and passes into said aperture in the head. Such an arrangement not only facilitates the insertion of the strap into the aperture in the head but also ensures that the locking coaction between the pawl and the strap is such that pullout of the strap from the head is prevented. In one embodiment, the floating pawl is eliminated and a wedgeinsert is provided severably attached to the head of the tie and adapted to be forced into wedging coaction in the head with the strap portion, to hold the latter in looped condition.
Abstract:
PROBLEM TO BE SOLVED: To provide a cable tie which can be used in an automated cable tie installation tool and has improved gripping of a large bundle or a small bundle. SOLUTION: A two-piece cable tie is provided that is capable of usage with an automated cable tie installation tool. The two-piece cable tie accommodates improved gripping of large or small bundles. By including a cored-out region near the neck, the cable tie can secure a near zero bundle size. By including a transverse pad on the bottom side of the cable tie strap near the cable tie head, the cable tie can be prevented from rotation relative to the bundle to which it is secured. A preferred cable tie strap has a wide recessed center section and high side rails that increase lateral clamping force. To resist barb inversion, the cable tie preferably includes a reinforcement area underneath the metal locking device when used with a strap having a recessed area. By maintaining relatively high side rails and a thin web section in the tip, the cable tie can achieve zero insertion force while maintaining sufficient strap rigidity and size to enable feeding of the strap through an automated cable tie installation tool.

Abstract:
PROBLEM TO BE SOLVED: To provide a two-piece cable tie including a support of a locking device which changes from a cantilever beam to a simple beam support when completely coupled. SOLUTION: The cable tie includes a strap 104 with a first end and a free end 138, a locking head having a strap accepting channel 122, and a metal locking device 136 having a mounted end fixed to a support of a locking head and a free end positioned in the strap accepting channel to form a cantilever beam and mounted within an anchoring housing region of the head. It has a central inwardly projecting groove 110 of a predefined width that defines a thinned portion extending along a longitudinal axis of the strap to the free end of the strap. The strap accepting channel has a channel width defined between an end wall and an inner wall. A ledge 116 that provides a support surface of the metal locking device and a V-shaped groove at the free end to improve flexibility of the strap are provided.
