Description to preferred embodiment

Anchor clamps with explanation are applicable to 25 pairs of electric wires that help in the hinge joint communication cable as shown.This numerical value is the standard of U.S.'s telecommunications industry; Clearly, can be applicable to other cable standards according to device of the present invention.

These anchor clamps generally are expressed as 4, and it comprises a locator main part 5 with extension planar section of upper surface 6 and lower surface 7.Upper surface forms a groove, as hereinafter said, be used to lay hinge joint module base 10, module base 10 be by with main body 5 on aligning alignment distance pole 11 and relative with this groove straight, and the distance pole 11 on the main body 5 is to match with the open-ended of module base.

Main element 5 has flexible, and one first edge and one second edge are arranged on upper surface 6.The tooth 15 at many intervals forms a long row along every edge, and protrudes from upper surface 6.It is in order to lay electric wire between cog that tooth 15 leaves the gap.The standard wire specification of U.S.'s telecommunications industry is between 22 to 28.Tooth 15 has the crown that can limit the electric wire displacement of inserting 15 in tooth.Tooth 15 can be made into the crown of alternate shape as shown in Figure 3 and Figure 4, breaks away from and enter the gap of between cog with the electric wire of assisting each bar to separate.As figure, tooth has first cover to have the crown 18 of rounding or dome-shaped end, and 15 in tooth is arranged crown 19 alternately, and crown 19 has the tip, and exceeds the horizontal plane of crown 18.The crown end is assisted the electric wire of separate wires centering.The gap that tooth is 15 is consistent with the gap of the dividing plate of arranging along the lateral edges of base 10 20.Form the groove of laying electric wire together with the center distance pole on the base.

The shape of crown can have various shapes, and these shapes will make the insulating coating that does not damage on the electric wire when between cog inserts and shifts out electric wire, and these shapes can not deviate from aim of the present invention simultaneously, but the crown in the accompanying drawing is better.As shown in Figure 4, tooth 18 extends to and is approximately higher than upper surface 6 about 7.6mm (0.3 inch) greatly and locates, it has a circular free end face that is limited by the upper surface 30 of band fillet arc, radius is 1.8mm (0.04 inch), free end face and dull and

stereotyped side

31 and 32 link together, and become the angle of one 60 degree mutually.Side 31 is connected with the surface 33 of the vertically arranged 0.25mm of being of a size of (0.010 inch) substantially with 32, on surface 33 and the tooth 19 with its facing surfaces 35 at a distance of 0.5mm (0.020 inch).

Surface

33 and 35 defines the nearest surface of 19 in tooth 18 and tooth.Surface 33 links to each other with drop edge 34, forms one 30 angle of spending with the vertical line on surface 6.The height of tooth 19 from lower surface 7 to terminal is the last free end face that 36 declines of 9.8mm (0.385 inch) lateral edge have a fillet arc, and lateral edge is in one 60 degree angles.The lower surface 35 links to each other with the surface, subsequently, is being higher than upper surface 65.9mm (0.233 inch), is higher than lower surface 77.442mm (0.293 inch) and locates surface 35 and link to each other with surface 37, and surperficial 37 become 30 to spend angles with the vertical line of upper surface 6.If when the layout on

surface

31,32,36 and 34,37 made the objectionable impurities influence wrap in the insulating material of wire conductor outside, the electric wire in the cable can be embedded into and take out within the specific limits.Arrive 1.42mm (0.061-0.056 inch) at a distance of 1.55 between the facing surfaces of the gusset piece element 16 that will discuss later on.The height of tooth (between the upper surface of crown and main element) is enough to lay at least one pair of electric wire, the electric wire of such first lateral support on base can be placed in 15 in tooth, and then, second can be embedded into that laterally to place as the patent No. be No.3, on 945,705 the United States Patent (USP) hinge joint module main body.Here we are in conjunction with this patent as a reference.In some execute-in-place situation, only fix electric wire with a toothrow 15, in other operational circumstances, electric wire will be inserted between the tooth on anchor clamps 4 both sides.The upper surface portion 36 of crown 19 generally is to use colour code, with the hinge joint operation that helps to carry out according to conventional practice.Further as shown in Figure 2, tooth 15 can rotate from the actual edge of main element, and is supported by the gusset piece of making by the mould of main element upper surface.Element 16 also be used for expansion slot or adjacent to the cable channel at edge to align the passage of each bar electric wire.Main element is made into to wear along following table the lateral edge of groove, if when must limit lateral moving, can be fixed on the stable surface.

Distance pole 11 is on upper surface, and the end face of the groove on asymmetric the upper surface that is adjacent to main element 5.One root or as shown in the figure a pair of have the rib 25 of spacing to form relative continuous surface, and these two ribs have longitudinally extended main element 5 is laid the module base with formation groove on upper surface 6.The spacing of rib 25 is used for laying base, and open-ended 22 of base 10 is set near the distance pole 11, in case base places in the groove, just aims at the lengthwise movement that base limits base 10 with it.The distance of the groove that is formed by rib 25 is to count into 8.1mm (0.34 inch) from the outward flange of base tooth on one side, and counting from opposed edges is 6.7mm (0.264 inch).The space that move the position that this distance provides electric wire to drop to 15 in tooth from module body.

Anchor clamps preferably by a kind of by the test method 93MP of ASTM (ASTM) D70 (13, be that the polymer with flexing resistance that 40NM (352 o'clock/pound) records constitutes 500PSTmin) with according to the multiaxis impact velocity of the method D3763 of ASTM (ASTM).Material is a kind of Merlon preferably.The Lexan141R of the general electronic corporation of pittsfield for example, the MA of the Miles company of Pennsylvania Pittsburgh, Miles Nakrolon2805, the Dow chemical company of available with Dow Calibre301.10.Anchor clamps flexible makes main element 5 can be from hinge joint module or base 10 crooked or peel off.By increasing the resistance that surface 33 and spacing between surperficial 35 can further reduce the electric wire that tooth moves between cog.

In operation, the base 10 of one hinge joint module can be fixed on the upper surface of main element 5, and the electric wire of segregate each bar communication cable is passed main element 5 by laterally laying and drops to and is laid between the gusset piece 16 on 15 in each tooth and the dorsal edge in the electric wire mounting groove that the base 10 by the hinge joint module forms.The module main body can be placed on the base 10 so that the contact element of the set support in electric wire and there is electrically contacted then.

Main body can be used a pair of tongs (not shown) simply or finish (if possible) by skill 2 usefulness thumb pressings with respect to the crimping of module base action electric wire is fixed on the base, and electrically contacts with the eliminating of the electric contactor that supports in the module body contact portion that insulate.At that time, second the cover electric wire can be placed on the main body and between the crown of tooth 15 to its pressurization with securing electric lines in a suitable position, be placed in the other end that forces electric wire and contact element on the main body until a cover cap and get rid of being electrically connected of insulation.
