Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As depicted in figs. 1 and 2, biting connecions earthing clamp is made up of clamping device 100, linkage 200, power assistant spring 400, support 300 4 part, except low by density, that conductance the is strong aluminium of the outer other parts of power assistant spring 400 is made.Wherein power assistant spring 400 is arranged in support 300, and linkage 200 is through power assistant spring 400 and be fixed by support 300, and controls clamping device 100 and be engaged.
As shown in Figure 3, clamping device 100 is made up of three parts, be respectively connecting axle 103, wire clamp ring 101 and interlock clasp 104, one end of the wire clamp ring 101 of two circular arcs is connected with connecting axle 103, make wire clamp ring 101 diameter of formation wire can be clamped completely, to increase the contact area between wire clamp ring and wire as far as possible.Occlusion place 102 adopts length to be that 1cm sawtooth pattern draw-in groove is closed, and can meet the engaging of certain size wire when operating, and shape, the length of sawtooth pattern draw-in groove can increase according to on-the-spot actual needs with quantity or reduce, reserve certain nargin simultaneously, facilitate adjustment.An interlock clasp 104 is respectively equipped with in the middle position, both sides of two wire clamp rings 101, conveniently be connected with the universal bar 201 in linkage 200, as shown in Figure 4, two wire clamp rings 101 can with connecting axle 103 for the center of circle rotates, under the effect of linkage 200, the aperture 105 of wire clamp ring 101 is not less than 180 degree.
Linkage 200 is made up of universal bar 201, universal bar connector 202 and stretching bar 203, universal bar connector 202 is vertically set on one end of stretching bar 203, and stretching bar 203 is positioned at the middle part of joint coupling 202, two universal bars 201 are connected to the two ends of universal bar connector 202.In addition, choosing of universal bar 201 position can change for the closed tense-lax of clamping device 100 according to the openings of sizes of clamping device 100 and power assistant spring 400.Ground wire operating lever is utilized to pull stretching bar 203 to drive universal bar 201 to draw wire clamp ring 101, make wire clamp ring 101 opened with certain angle, universal bar connector 202 compresses power assistant spring 400 under the effect of stretching bar 203 in the process, completes the energy storage to power assistant spring 400.In the moment that ground wire operating lever is threaded off, power assistant spring 400 discharges elastic potential energy promotion linkage 200 and impels clamping device 100 to sting tight wire, is grounded the installing of line conductor end; Form mechanical latching between linkage 200 and power assistant spring 400 prevents clamping device 100 from loosening due to earth connection Action of Gravity Field and coming off simultaneously.
When arranging power assistant spring 400, the less spring met the demands again of demand fulfillment power assistant spring 400 coefficient of elasticity, to reduce the requirement to operating personnel's arm strength.
As shown in Figure 5, support 300 is used for supporting clamping device 100 and linkage 200, support 300 adopts three limit formula rectangular design, the circular hole 301 at top is for fixed connection shaft 103, and it is up and down for stretching bar 203 that middle part of going to the bottom leaves the circular hole 303 slightly longer, shorter than power assistant spring 400 diameter than stretching bar 203 diameter.The side of support 300 is provided with two bolt slots 302 and is convenient to installing bolt dead earth line.
The utility model adopts the mode of occlusion to be grounded the installing of line conductor end first, action bars is utilized to pass through to compress power assistant spring 400 while stretching bar 203 drives linkage 200 to pull open clamping device 100, the resilience realizing power assistant spring 400 in the moment that action bars is threaded off impel clamping device 100 to sting installing that tight wire completes conductor end of earth wire, forms mechanical latching simultaneously and prevents wire clamp ring from loosening due to earth connection Action of Gravity Field and coming off between linkage 200 and power assistant spring 400.
