Embodiment
Below by way of embodiment, and the invention will be further described by reference to the accompanying drawings.
See Fig. 1 ~ Fig. 5, cable gripper of the present invention, comprises framework, mounting plate 4 and is arranged at the cramping body of two symmetrical settings on described mounting plate 4, be clamped between described two cramping bodies by clamped cable 12; Described cramping body comprises two cams, 1, torque spring, 7, four synchromesh gears; To be clamped between two cams 1 by blessing cable 12 and to contact with two cams 1, described cam 1 be involute by the profile line accommodating the nip side that cable 12 contacts; Described cam 1, torque spring 7, synchromesh gear are all installed on mounting plate 4; Torque spring 7 is provided for after cam 1 rotates and can automatically resets, and makes cam 1 can clamp by clamped cable 12; Synchromesh gear comprises two active synchronization gear 2-1 and two driven synchromesh gear 2-2; Wherein two active synchronization gear 2-1 and cam fixture block synchronous axial system; Four synchromesh gears form chain type engagement, and when some cam fixture blocks 1 rotate, another cam fixture block thereupon synchronous backward rotates, and synchronously opens or synchronizing close to realize two cam fixture blocks.
Described cam 1 nip side involute is similar to logarithmic spiral.The polar equation of logarithmic spiral is:
, wherein r is footpath, pole; α is the angle of footpath, pole and helical tangent line; θ is polar angle; E is the end of natural logarithm, e=2.7182 Ctg is cotangent.Its mechanical characteristic realized is: the footpath, pole of cam 1 be a constant by the holding angle of clamped cable 12, have nothing to do with by the diameter of clamped cable 12 or thickness.
The main body of described cam 1 is made with insulating material such as bakelite, ebonite, engineering plastics.To the clamp face of cam 1 with by the requirement of the coefficientoffrictionμ of clamped cable 12 be: μ >=tg α, wherein α be cam 1 footpath, pole with by the holding angle of clamped cable 12, tg is tan.When being subject to downward pulling force by clamped cable 12, this mechanical structure makes it does not pulled being produced enough frictional force by clamped cable 12.
This cable gripper also comprises the simplified mode of another kind of single cam structure.As Fig. 5, this cable gripper is drawn together framework, mounting plate 4 and is arranged at cramping body described in the cramping body of a symmetrical setting on described mounting plate 4 and comprises a cam 1, fixed clamp plate 13, is clamped between described cam 1 and fixed clamp plate 13 by clamped cable 12.As Fig. 5, it is a kind of cable gripper of the simplified mode of single cam structure.Single involute cam 1 forms clamp face 3 with fixed clamp plate 13, and cable 12 is clamped between involute cam 1 and fixed clamp plate 13.Compared with double cam-type cable gripper, single cammingly cable gripper eliminates an involute cam 1, torque spring 7 and 4 synchromesh gears 2-1,2-2, volume-diminished, designs simplification.Compared with double cam-type cable gripper, single cammingly cable gripper still can realize every mechanical property of described cable gripper of the present invention, operating method is also identical, caught object can not be still μ >=tg α by the necessary and sufficient condition pulled, only by maximum diameter the reducing by half than double-cam structure of clamped cable.
In Fig. 4, cable gripper main body is made up of the cam that two have certain evolvent profile, has torque spring and synchronous mechanism between two cams, and two cams can be made synchronously to close up to central or separate to both sides.Cam closes up under the effect of torque spring at ordinary times.When the cable be fixed inserts in the middle of two cams of clamp holder, cam separates automatically, and insertion force is very little.After inserting, cam compressing cable surface produces frictional force, and this frictional force can stop cable to pull out.Suitably choose the shape of cam material and cam curve, such mechanics effect can be reached---no matter external pull has much, all cable can not be pulled out from clamp holder.During dismounting cable, manually oppositely exert a force to cam, overcome spring torsion, lazy-tongs separate cam to both sides, and namely cable contacts with cam disengages and automatically deviate from.
Obviously, the technical program has the following advantages:
(1) load and unload cable and need not use the special tools such as spanner;
(2) charge and discharge operations simple and fast is laborsaving;
(3) impacting force is generated automatically by clamp structure, and impacting force is little under normal circumstances, and when cable is pulled by brute force, impacting force increases thereupon, is not pulled as degree, avoid operation accident and cable fault to greatest extent with cable;
(4) cam clamp face insulating material is made, and can not hurt cable or cause short circuit;
(5) can the on-the-spot various diameter of self adaption, variform flat and round cable, electric wire, and press the cable core of line nose;
(6), after cable is extracted out, wire-feeding hold is closed automatically, prevents dust, toy etc. from entering;
(7) this holder structure is simple, and element is sturdy, not fragile;
This clamp holder can be used as an individual components, is arranged on the wire outlet hole place of various distribution box, does not affect layout in the housing structure of distribution box, mechanical strength, case, and the realization of other function.
Logarithmic spiral, also known as equiangular spiral, is the one of involute.Its polar equation formula is:
Wherein:
R---footpath, pole (in figure OA line segment)
The angle (in figure A point) of α---footpath, pole and helical tangent line
（0＜α＜π α≠π/2）
θ---polar angle (θ ∈ (-∞ ,+∞))
The end (the e=2.7182 of e---natural logarithm ...)
Ctg---cotangent
A key property of logarithmic spiral is: on curve any point, and the angle α of footpath, pole r and helical tangent line is a steady state value.This adopts logarithmic spiral as the main cause of clamp holder involute cam fundamental curve in the technical program.
