Abstract
A stretched cable tie has a head connected to a strap having teeth on both sides of the strap. A moveable pawl is positioned on a ledge inside the head and urges the strap into engagement with a fixed tooth within the head so that teeth on both sides of the strap are engaged by the pawl and fixed tooth respectively. A sharp corner is provided more than a multiple of the spacing between the strap teeth below the fixed tooth so as to allow the corner to penetrate the strap and engage the adjacent tooth to aid in providing a withdrawal force. A portion of the wall of the head behind the fixed tooth is removed to facilitate cooling and eliminate shrinkage in the area of the fixed tooth.
Claims23
A stretched cable tie comprising a head and a strap having a plurality of teeth on both sides of said strap;
- said strap having been stretched from its as-molded condition to lengthen both said strap and the as-molded spacing between said teeth;
- said head having an abutment wall connected to a pair of spaced side walls having an entry face and an exit face with a strap receiving aperture extending therebetween;
- said abutment wall having a fixed tooth extending into said strap receiving aperture intermediate the entry and exit faces, said fixed tooth having a locking surface facing toward said exit face;
- and
- a pawl mounted for movement in said head having a single pawl tooth extending into said strap receiving aperture, said tooth being adapted to engage one of said teeth when said strap is positioned through said strap receiving aperture and a force is applied in a direction toward said strap entry face to a portion of said strap within said head.
A stretched cable tie having a head and a strap with a plurality of teeth on each side of said strap;
- said strap having been stretched from its as-molded condition to lengthen both said strap and the as-molded spacing between said teeth;
- said head having a pair of spaced side walls joined by an abutment wall;
- said head further having a strap entry face and strap exit face with a strap receiving aperture extending therebetween;
- a fixed tooth extending from said abutment wall into said strap receiving aperture, said fixed tooth having a locking surface facing toward said exit face;
- said abutment wall having a sharp corner positioned more than a multiple of the distance between said strap teeth toward said entry face from said fixed tooth;
- a pawl mounted for movement in said head having at least one pawl tooth extending into said strap receiving aperture, said tooth being adapted to engage one of said teeth when said strap is positioned through said strap receiving aperture and a force is applied in a direction toward said strap entry face to a portion of said strap within said head.
A stretched cable tie comprising a head and a strap extending therefrom having a plurality of strap teeth on both sides of said strap;
- said strap having been stretched from its as-molded condition to lengthen both said strap and the as-molded spacing between said teeth;
- said head having an abutment wall connected to a pair of spaced side walls having an entry face and an exit face with a strap receiving aperture extending therebetween;
- said abutment wall having a fixed tooth extending into said strap receiving aperture intermediate the entry and exit faces, said fixed tooth having a locking surface facing toward said exit face;
- a pawl mounted for movement in said head across the strap receiving aperture from said fixed tooth, said pawl having at least one pawl tooth extending into said strap receiving aperture, said tooth being adapted to engage one of said teeth when said strap is positioned through said strap receiving aperture and a force is applied in a direction toward said strap entry face to a portion of said strap within said head;
- and
- a portion of the abutment wall being relieved so as to permit cooling of said head without shrinkage in the area of said fixed tooth.
