Abstract:
There is provided a cable tie (100) comprising: a cord (101) having a first end (102) and a second end (103), which cord comprises cellulosic fibers; and a locking head (104) fixedly attached to the first end (102), said locking head (104) being adapted to receive the second end (103) and retain the cable tie (100) in a closed loop configuration, wherein said locking head (104) defines (a) wall(s) (105) that encircles a passage (106) having an inlet (107) and an outlet (108) and comprises a metal blade (109) that extends into the passage (106) for engaging the cord (101) and which is arranged to allow displacement of the cord (101) in a first direction towards the outlet (108) while preventing displacement of the cord (101) in a second direction towards the inlet (107).
Abstract:
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 is it 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:
A two piece cable tie is provided having an improved locking device support. The cable tie includes a strap with a first end and a free end, a locking head having a strap accepting channel, and a metal locking device mounted within an anchoring housing region of the head to form a cantilever beam having a mounted end fixed to a support of the locking head and a free end positioned within the strap accepting channel. The strap includes a central inwardly projecting groove 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 W1 defined between an end wall and the inner wall The strap accepting channel also includes a support guide projecting from the inner wall of the locking head into the strap accepting channel to restrict the width of the channel accepting channel to a width W2, which is less than W1. The free end of the metal locking device has a length L that is greater than W2 and preferably no greater than W1. The support guide has a width transverse to the width of the strap accepting channel that is less than the predefined width of the projecting groove of the strap. The support guide also includes a ledge that provides a support surface for the metal locking device that changes the locking device from one having a cantilever support to one with a simple beam support when the locking device is bent downward by a sufficient withdrawal force. This withdrawal force is sufficient to cause the locking device to fully pierce the thinned portion of the strap, which allows the free end of the locking device to rest upon the ledge. The strap may include a V-shaped groove at the first end to improve flexibility of the strap.
Abstract:
A two-piece cable tie is provided that can be more readily assembled and achieves a low insertion force while maintaining desired strap retention force. The cable tie includes a metal locking device that is bent at a predetermined bend angle and then precisely located within a locking device receiving cavity. The cable tie includes a strap including a first end and a free end and a locking head secured to the first end of the strap along a strap attachment axis. The locking head includes a strap accepting channel in the head that has a strap entry end and a strap exit end on opposite ends of a strap accepting channel axis. The strap accepting channel divides the locking head into a first part and a second part, with the first part being secured to the first end of the strap and the second part including metal locking device receiving cavity adjacent to and open toward the strap exit end of the locking head and an extending wall located between the receiving cavity and the strap accepting channel. The metal locking device, which is preferably prebent, is mounted within the metal locking device receiving cavity by having a fixed end mounted to a support slot of the end wall of the locking head and oriented substantially parallel to the strap accepting channel axis. The metal locking device further includes a free end angled at an acute angle relative to the strap accepting channel axis and extending into the strap accepting channel. When mounted, the free end preferably substantially rests upon a fulcrum point of the extending wall and extends beyond the wall by a predetermined distance into the strap accepting channel.
Abstract:
A two-piece cable tie including a strap and a locking head forming a strap accepting channel with a metal locking wedge positioned within the channel and mounted to the locking head including a groove formed by coining on the embedded end of the metal locking wedge to increase the pull out force of the locking wedge without the need to cut out material of the locking wedge. The coined groove also avoids weakening of the flexure region and still allows for a decrease of the threading force of the cable tie strap.
Abstract:
A cable tie includes a head having an elongate passage therethrough and a strap insertable into the head. The head includes a metallic barb supported therein which extends into the passage for locking engagement with the strap. The barb includes a portion embedded into the head and a portion extending therefrom. A cable tie exhibiting high withdrawal or pull-out strength with low strap insertion force is obtained by significantly increasing the length of the unembedded portion of the barb with respect to both the embedded portion and the thickness of the strap.
Abstract:
The invention relates to a device in a cable tie. This comprises an elongate band part (2) of a certain width and thickness, which at one end has an elongate insertion part (2a) of a lesser width than the band part (2) and at its other end a locking head (3) with, on the one hand, a through-opening (4) for the band part (2), which has largely the same width as the band part (2) but a height greater than the thickness of the band part (2), and on the other a slit (5) in one transverse wall of the opening, the width of which slit is such that it will allow the insertion part (2a) to be inserted into the opening (4) via the slit (5), forming a band loop. A tongue (6), which is designed to lock the band part (2) in relation to the locking head (3), extends from one end of the opening (4) to the other and towards the slit (5). A sheet-metal insert (7) reinforcing the locking head (3) is embedded in the locking head (3).
Abstract:
A low profile cable tie, preferably a two-piece cable tie, has a low profile locking head with a lateral strap accepting channel and a strap preferably molded with a right angle bend that is retained in this state during non-use. The cable tie has a clean exterior appearance, including a top surface free of openings and a smooth lateral opening. With this cable tie, a strap accepting channel is provided in the locking head that is substantially parallel to a strap attachment axis. The strap accepting channel divides the locking head into a first part, which is secured to the strap, and a second part which contains a locking device. By providing the locking device on the second part, the first part can be made thinner, allowing the strap accepting channel to be closer to the cable bundle being tied. Further, in the case of a two-piece cable tie having a metal locking device, the locking device is preferably bent so as to have a fixed end substantially parallel to the strap accepting channel axis and a free end positioned within the strap accepting channel at an acute angle relative to the strap accepting channel axis. A bottom wall may be shorter in length than an upper wall to define a recessed inset that widens the effective strap accepting channel entrance without increasing the height of the locking head. The inset also allows entrance of the strap over a broader range of entrance angles.
