Abstract
The forceps (1) with stripping device for insulating layer comprises a single forceps body (2) with back part composed by stable handle (3) and front part formed a fixed clamp claw (4), a movable clamp claw (5) symmetric to fixed claw (4), a handle (7) combined with gear part (6) to support forceps with bearing axle neck (8), a toggle joint (9) to drive movable claw (5), and a couple of shearing claws (12, 13) with clippers (11) to form a interlink with a drafting element (140) to cut in insulating wrappage on first stage and strip the insulating wrappage from back end of conductor on second stage when the drafting element executes the stripping operation; wherein, the control device (130, 15) ensures the determined stripping length.
Description
Technical field
The present invention relates to a kind of pliers with insulating barrier device for stripping, in order to peel off the insulating barrier of conductor ends, it comprises the caliper of a single-piece, and its rear portion is made of the motionless handle above one and its front portion constitutes the form of a fixing clamp jaw; Also comprise: one on caliper supporting swingably and the movable clamp jaw that is opposite to fixing clamp jaw; That one and one drive disk assembly fuses and be bearing in following handle on the caliper swingably via this drive disk assembly and a bearing journal; One is steerable and drive the toggle of movable clamp jaw by drive disk assembly, and a pair of shearing pawl that is provided with scissors between each clamp jaw, it becomes a binding with a traction element, and its when handling pliers at the insulating covering of phase I incision conductor and in second stage from the end that has cut off that conductor ends is peelled off insulating covering, implement this by the traction element that is promoted by toggle and peel off motion this moment.
Background technology
By the known a kind of pliers that has with category feature of EP 0 562 229 B1.
The pliers of describing in document chapters and sections also has other processing unit (plant), and in order to the processing conductor ends, for example a beader and is used to separate the shear of electric conductor.
It is suitable substantially that these pliers have proved in practice.
The equipment that is used to peel off the insulating barrier of conductor ends in above-mentioned pliers finally works according to power.At first apply a clamping force via handle, toggle and movable clamp jaw,, and and then power is brought up to till the incision insulator so that clamp conductor ends.
In the flow process that continues, peel off insulation then, wherein in known pliers because the friction in the whole equipment finally can not accurately be determined strip length.
Summary of the invention
Therefore the objective of the invention is to, further develop such pliers targetedly, make it can reach an exactly determined insulating barrier and divest length.
Reach like this according to this purpose of the present invention, thereby promptly peel off motion and guarantee that the insulating barrier of determining divests length according to displacement control by a control device.
Therefore avoid reliably going in the process of insulating barrier because the fault that insulating bag skin bit that not exclusively peel off from conductor, cut-out occurs in conductor ends.
A kind of form that can realize especially simply of control device is that control device comprises one at the control cam that is shaped on the angle lever of the control cam that is provided with on the movable clamp jaw and at toggle and lead on the control cam.
Therefore control device comprises device pure machinery and that can make at an easy rate and that in fact do not improve the cost of this pliers.In addition, even this control device also has lasting operate as normal ability in frequent regular job.
Description of drawings
One embodiment of the present of invention are shown in all accompanying drawings, below give to describe in more detail.Wherein:
Fig. 1 pliers of the present invention is in the cutaway view of open configuration;
Among Fig. 2 Fig. 1 with the zoomed-in view of the thin portion of II mark;
Fig. 3 pliers of the present invention is in the profile in the centre position of an operation;
Among Fig. 4 Fig. 3 with the zoomed-in view of the thin portion of IV mark;
Fig. 5 pliers of the present invention is in the profile of the terminal location of an impulse stroke;
Among Fig. 6 Fig. 5 with the zoomed-in view of the thin portion of VI mark.
Embodiment
Fig. 1,3 and 5 illustrates with a vertical section of simplifying respectively that of the present invention it has the caliper 2 of a single-piece totally with the pliers of mark 1 expression, and its rear portion is made of the motionless handle 3 above one and its front portion constitutes the form of a fixing clamp jaw 4.
Below fixing clamp jaw 4, supporting another clamp jaw 5 swingably on the caliper 2.
In addition, on caliper 2, support a handle 7 below 6 one-tenth bindings of drive disk assembly swingably.The wherein supporting that can swing via a bearing journal 8 realizations, this bearing journal 8 passes drive disk assembly 6 and caliper 2.
Borrow its exercisable toggle 9 movable clamp jaw 5 can be driven around the direction of a bearing pin 10 to an inclination or oscillating motion via drive disk assembly 6 and.
Between fixing clamp jaw 4 and movable clamp jaw 5, be provided with and cut 11 shearing pawl 12 and 13 and can vertically move, wherein shearing pawl 12 is connected with a traction element 140 that prolongs with 13 one-tenth one, this traction element 140 is when handling pliers 1, that is pressing handle 3 and 7 o'clock, by the toggle 9 that works backward to the direction of two handles 3 and 7 this moment by backward, promptly to the direction motion of two handles 3 and 7.Correspondingly shearing pawl 12 and 13 this moment moves to equidirectional.
If pliers 1 is outwards opened once more from this terminal location by discharging two handles 3 and 7, traction element 140 and shear pawl 12 and 13 thus then also because the effect of spring of starting moves on to the original position of its front once more.
In clamping claw 4 and 5 and shear formation one spatial accommodation 120 between the pawl 12 and 13, wherein under the open configuration of pliers, can insert the end of an electric conductor.If after a conductor ends is inserted spatial accommodation 120, handle pliers 1 by compressing two handles 3 and 7, then at first conductor ends is clamped between clamp jaw 4 and 5, and then shear in the insulating barrier or insulating covering of scissors 11 incision conductor ends of pawl 12 and 13, and in the end pressing handle 3 and 7 o'clock are peelled off the insulating covering part of having cut off by the two above-mentioned motions of peeling off of shearing pawls 12 and 13 to the direction of two handles 3 and 7 from conductor.
Thus clamp jaw 4 and 5 and shear pawl 12 and 13 with its scissors 11 formations one insulating barrier device for stripping, in order to peel off the insulating barrier of conductor ends.
The function of above-mentioned pliers 1 is known by EP 0 562 229 B1 also basically and has described the operation of carrying out in detail here, therefore mentions this document here once more.
The scope that exceeds known pliers structure is provided with a control cam 130 according to pliers 1 of the present invention on movable clamp jaw 5.One with the angle lever 14 of drive disk assembly 6 crew-served toggles 9 in its lower section, be provided with a control cam 15 towards the end of control cam 130.This control cam 15 is along control cams 130 guiding, and the configuration that will control cam 130 is chosen to, and makes that when implementing the complete in opposite directions toward each other deflection of two handles 3 and 7 then toggle 9 can open at first once more.
Produce two thus and shear moving of pawls 12 and 13, it is equal to peels off motion, in order to peel off the insulating covering that has cut off part on the conductor ends, promptly a definite insulating barrier divests length.This peels off motion this moment because control cam 13 and control cam 15 crew-served with it have nothing to do according to the displacement Be Controlled and with intrasystem friction.
Advantageously, 130 one-tenth one on cam of control is formed on the movable clamp jaw 5.Perhaps also can imagine basically, control cam 130 is made independent member and be fixedly connected on the movable clamp jaw 5 in mode arbitrarily to this.Its special advantage is also can correspondingly be provided on the existing pliers.
Fig. 1,3 and 5 and detail drawing 2,4 under each and 6 with described order original position or resting position, a centre position and the terminal location of pliers 1 in the insulating barrier strip are shown.
