Specific embodiment
The optimal technical scheme that according to the present invention will be described in detail below with reference to the accompanying drawings.
A kind of copper bar fast fixture comprising protective shell 1, fixation kit 2 slide hold down assembly 3 and latch assembly 4
Composition.
As depicted in figs. 1 and 2, protective shell 1 divides to pass through spiral shell between upper casing 11 and lower casing 12 comprising upper casing 11 and lower casing 12
It is fixed to follow closely 1.
There are slot-type openings convenient for copper bar insertion at the top of upper casing 11 and lower casing 12；There are cross line for upper casing 11 and 12 bottom of lower casing
Connecting cable is convenient in hole.
Upper casing 11 and lower casing 12 use insulating materials, preferably insulation ABS.
Fixation kit 2 includes that rack 21, elastic fixture block 22, sliding sleeve 23 and screw 2 24 form.
Shown in Fig. 3 and Fig. 4,21 shape of rack is Y type, and left side is equipped with screw hole 211 and limit card slot 212, is used for bullet
The fixation of property fixture block 22.Centre is equipped with cable jack 213.Right side is equipped with hinge hole 214, for consolidating for cam 33 and pawl 41
Fixed, bottom is equipped with cable crimp head 215.Type of attachment uses and crimps form between middle cable connector 215 of the present invention and cable, but
Do not limit to the form only with crimping, the forms such as copper lug connection can also be used.
21 material of rack is preferably brass.
Shown in Fig. 5 and Fig. 6,22 shape of elastic fixture block be it is trapezoidal, have elastic clamping face 221, copper bar clamp state
Under, flexible deformation occurs for elastic clamping face, and shape is rectangle by trapezoidal distortion, has not only increased the clamping torque of copper bar, but also protect
Effective contact area of copper bar is demonstrate,proved.Elastic fixture block 22 is T-type, and boss 222 is equipped with threaded hole 223, boss 222 and limiting card
Slot 212 plays position-limiting action for cooperating.
Fixed by screw 2 24 between elastic fixture block 22 and rack 21 is only a kind of its optimal scheme, in order to work as bullet
Property fixture block 22 wear after can be convenient for changing.It can also be an integral structure form using elastic fixture block 22 and rack 21.
22 material of elastic fixture block is preferably brass, and 221 surface preferred process scheme of elastic clamping face is embossing processing, to increase
The contact area of big electric conductor.
It 3 includes that slide bar 31, connecting rod 32, cam 33, swivel pin 34 form that sliding, which holds down assembly, and sliding holds down assembly 3 and solid
Determine the composition slider-crank mechanism of component 2 to be driven by the sliding of slide bar 31 by connecting rod 32, is ultimately converted to the rotation of cam 33.
Cam clamping mechanism is formd again between cam 33 and fixation kit 2, to realize the clamping to copper bar.
There is T-type platform at the top of slide bar 31, as the face cooperated with copper bar, T stage protrusion is partially contained in limit card slot 212
Interior, playing slide bar 31 described in position-limiting action can be along 23 slide downward of sliding sleeve under the reaction force acts of copper bar.
It is connected between connecting rod 32 and slide bar 31 and cam 33 by swivel pin 34.
32 quantity of connecting rod is two, is respectively arranged in the positive and negative two sides of slide bar 31.
Shown in Fig. 7, the arc-shaped edges of cam 33 are seal face 331, and ratchet 332 is designed in lower end.What cam 33 rotated counterclockwise
Gap between process seal face 331 and elastic clamping face 221 reduces therewith, to play the role of clamping copper bar.
Seal face 331 is equipped with anti-skid structure, is handled in the present invention using embossing.
Ratchet 332 can prevent cam 33 to be rotated clockwise under 34 mating reaction of pawl.
Cam 33 is fixed in rack 21 by swivel pin 34.
Latch assembly 4 includes pawl 41, unlock drawstring 42.Pawl 41 is by being hingedly fixed in rack.And pawl 41 with
Reset spring is equipped between rack 21.Pawl 41 is used cooperatively with the ratchet 332 on cam 33, it is ensured that cam 33 can turn counterclockwise
It is dynamic, locking clockwise.
When needing to unclamp, it is only necessary to tense unlock rope 42.I.e. disengagable pawl 41 is to unlock.
Unlock rope 42 is isolation material, preferably insulated nylon rope.
Such as Fig. 2, when operation first according to the thickness of copper bar and adjustment confirmation seal face 331 and elastic clamping face 221 it
Between gap, this gap should be 2-5mm bigger than copper bar thickness.The rectangle gap on copper bar fast fixture top is directed at copper bar, so
After enforce fast fixture.After copper bar is contacted with slide bar 31, under the reaction force acts of copper bar, slide bar 31 can be along cunning
Set 23 moves downward.Under the drive of slide bar 31, connecting rod 32 will drive cam 33 and rotate counterclockwise.As cam 33 turns counterclockwise
Gap between dynamic seal face 331 and elastic clamping face 221, which constantly reduces, plays the role of clamping copper bar.With further depth
Enter, flexible deformation occurs for the elastic clamping face 221 of elastic fixture block 22.The clamping force of copper bar, another party are on the one hand improved in this way
The contact area that face increases.After it is rectangle that elastic fixture block is by trapezoidal distortion, copper bar clamping device can not promote further along.?
Ratchet 332 and 41 mutual cooperation of ratchet effect prevent cam 33 to rotate backward during this, to play fixed locking
Effect.The operation process of copper bar fast fixture so far connecting with copper bar is completed.It is when needs are separated with copper bar, only
Need to tense unlock rope 42, ratchet 41 is in the unlocked state at this time, and cam 33 can rotate clockwise, and exerts oneself at this time copper bar is fast
Fast attachment device is extracted, and under the action of frictional force, seal face band moving cam is rotated clockwise, seal face 331 and elastic clamping
Gap becomes larger between face 221, and flexible deformation is restored in elastic clamping face 221.Final copper bar fast fixture and the copper bar realized
Separation.
Above-described specific embodiment, to the purpose of this utility model, technical scheme and beneficial effects carried out into
One step is described in detail, it should be understood that being not used to limit the foregoing is merely specific embodiment of the present utility model
The utility model processed, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done,
It should be included within the scope of protection of this utility model.
