Above-mentioned two embodiment are merely the advantageous applications example of technical scheme of the present invention; Be not to limit its multifarious execution mode with this; Like versions such as the form of clamp lobe cylindrical tapering and the additional mask that on the basis of citation form, derives, sealings, all within the interest field that the present invention requires to protect.
When making the clamp lobe, can be that circular cone, endoporus are that the circular cone ring of circular hole cuts open and is seamed at least two clamp lobes by periphery, the interior circular hole of clamp lobe be that light face or inner hole surface are processed into concavo-convex; The whole periphery of clamp lobe is a taper seat, or clamp lobe periphery is the combination of the face of cylinder and taper seat.During batch machining, the method that adopts injection moulding is to improve work efficiency.
Shown in Figure 4, the clamp lobe receives the coupling mechanism force from cable cover or pressure ring, produces the normal pressure to cable, and wherein A-A and B-B cross section produce the normal pressure that numerical value is Na and Nb respectively, and produces frictional force fa and the fb that overcomes pulling (turning round) the power T from cable thus.
As far as embodiment one; Cable is significantly less than original cable outside diameter by (as shown in Figure 5) under the stitching state by pressing position insulating outer layer diameter of phi A, Φ B; Because the degree from cable cover or the pressing of pressure ring tapering is different; In the pressing amount in the A-A cross section pressing amount greater than the B-B cross section, promptly Φ A is less than Φ B.When pulling (turning round) the power T from cable increases; Make cable produce axial displacement with respect to the clamp lobe; Large tracts of land cooperates the big frictional force that produces between them except that overcoming, and original cable outside diameter must be compressed to Φ B size and could realize, and Φ B is significantly less than original cable outside diameter; Can't realize this compression, the practical like this high reliability that has guaranteed the clamping locking of cable.
As far as embodiment two, cable is reverse by (as shown in Figure 6) Φ A, Φ B and embodiment one under the stitching state, that is to say, and the pressing amount in the A-A cross section, the outer diameter of phi A of the pairing minimum cable insulation of promptly maximum pressing amount is near the wire bushing end.When pulling (turning round) the power T from cable increases; Make cable produce axial displacement with respect to the clamp lobe; Except that the frictional force that overcomes between them, original cable outside diameter must be compressed to Φ A size and could realize, and Φ A is the minimum diameter size; Can't realize this compression more, further guarantee high reliability the clamping locking of cable.
Shown in Figure 7, in traditional clamp mode, after the pressing of clamp to cable, the no change on stitching surface of the diameter of phi A after the cable pressing.The tradition clamp for the clamp lobe, the one, width is less, the 2nd, the goodness of fit was bad when its intrados and cable insulation skin cooperated, thereby its clamp area is less than normal, the clamping locking effect is poor than the clamp lobe.
Shown in Figure 8; Adopt wire clamp clamping cable external insulation layer, the wire clamp reed receives the coupling mechanism force of back nut, produces the normal pressure to cable; Wherein A-A and B-B cross section produce the normal pressure that numerical value is Na and Nb respectively, and produce frictional force fa and the fb that overcomes pulling (turning round) the power T from cable thus.By finding out the A-A section cable maximum that is stressed among the figure, normal pressure Na and frictional force fa are also maximum, and at the B-B section, because of the reed root does not produce pressing, so that normal pressure Nb and frictional force fb approach is zero.This moment, it was significantly less than original cable outside diameter by stitching state (as shown in Figure 9) by pressing position insulating outer layer diameter of phi A as far as cable.Because the root of reed does not produce pressing, promptly Φ B size equals original cable cylindrical, and like this at the cable stitching surface, promptly between section A-A and B-B, having formed a maximum cylindrical is that Φ B, minimum cylindrical are the formed taper seat of Φ A.Cable will produce axial displacement with respect to wire clamp, and the cable cylindrical must be compressed to minimum dimension Φ A, and cable by the pressing part, cable can strut the wire clamp reed along the guiding of outer conical surface, for the realization of this displacement provides maybe; Simultaneously, wire clamp belongs to a contact with contacting of cable insulation, and little with the clamping face of cable, frictional force is less than normal.When cable received bigger pulling (turning round) power T, cable will produce axial displacement with respect to wire clamp, and clamping locking was lost efficacy.
Complex chart 7,8,9; That the wire clamp structure only limits to is less demanding to the cable clamping, tension requires low environments for use such as radio frequency coaxial-cable; To the bigger cable of diameter difference, tension drag, the demanding environment for use suitability of antitorque commentaries on classics is relatively poor, can not satisfy the requirement of tension, torsional property.
