Abstract
The invention relates to a straight-tongs ground wire, pertaining to the technical field of electrical equipment safety inspection devices. The ground wire comprises an insulated hand grip and a wire clip connected with the upper end of the hand grip. The wire clip comprises a clip seat which is provided with a terminal and two relative wire-clip heads; two press springs which push to open the two wire-clip heads are arranged between the two wire-clip heads; the lower ends of the two wire-clip heads are hinged to the wire-clip seat respectively; the inner flanks of the lower ends of the wire-clip heads form a cant; a slide block is arranged at the lower ends of the wire-clip heads, and the slide block is restricted inside the clip seat and capable to slide along the central lines of the two wire-clip heads; the action cant formed on the both ends of the slide block matches the cant at the inner flanks of the lower ends of the wire-clip heads; the lower end of the slide block matches and is connected with the bolt threads arranged at the upper end of the insulated hand grip. The straight-tongs ground wire is easy to hold, capable to improve the working efficiency, and settles the problems of the prior art that the wire-clips at the end of a conductor are not easy to hold the conductor, the working efficiency is low, etc.
Description
Technical field
The present invention relates to a kind of straight-clamping type grounding wire, belong to the technical field of electric equipment safety inspection device.
Technical background
A kind of intelligent sound alarm short-circuit earth connection (notification number: CN2706888), it comprises that head end is provided with the action bars of conductor end wire clamp, the short-circuit line and the ground lead of two ends difference bonding conductor end terminal and earth terminal wire clamp, be respectively equipped with on described conductor end wire clamp and the earth terminal wire clamp and chuck action associated switch circuit, described switching circuit links to each other with singlechip controller, described singlechip controller is connected with speech chip and according to switching circuit control speech chip, described speech chip connects the voice output circuit.Comparatively inconvenience when the conductor end wire clamp of above-mentioned earth connection and conductor clamping, operating efficiency is lower.
Summary of the invention
Problems such as the object of the invention is to provide a kind of clamping convenient, and the straight-clamping type grounding wire that can increase work efficiency is comparatively inconvenient when having solved conductor end wire clamp that prior art exists with the conductor clamping, and operating efficiency is lower.
Above-mentioned technical purpose of the present invention mainly solves by the following technical programs: it comprises insulated handle and is connected the wire clamp of handle upper end, described wire clamp comprises the wire clamp seat wire clamp head relative with two with binding post, be provided with the stage clip that the ejection of two wire clamp heads is opened between two wire clamp heads, two wire clamp head lower ends are hinged with the wire clamp seat respectively, the inboard inclined-plane that forms, the lower end of wire clamp head, described wire clamp head lower end is provided with slide block, slide block is limited in can sliding along the center line of two wire clamp heads in the wire clamp seat, the upper end of slide block both sides form the action inclined-plane and cooperate with the inclined-plane of inboard, wire clamp head lower end, and the slide block lower end is connected with the bolt thread of establishing with the insulated handle upper end.Working as two wire clamp heads during use is under the state of being opened by the stage clip ejection, even two wire clamp head-clamps are lived the lead lead between two wire clamp heads, then turning handle makes between the bolt of handle upper end and the slide block and relatively rotates, thereby slide block is moved up, the ramp effect of the action inclined-plane of upper end of slide block and inboard, two wire clamp head lower ends forces two wire clamp heads to overcome the active force of stage clip and closes up, thereby lead is clamped, and the whole operation process is very convenient, has improved operating efficiency; Simultaneously, two wire clamp heads are also very reliable to the clamping of lead, improved the fail safe of ground connection operation.
As preferably, be connected with lead between described wire clamp head and the wire clamp seat.Wherein, lead has been strengthened being electrically connected between wire clamp head and the wire clamp seat, has improved the reliability of ground connection.
As preferably, inboard, described two wire clamp heads upper end is respectively equipped with recess.Wherein, the recess on the wire clamp head can guarantee the reliable clamping of two wire clamp heads to lead.
As preferably, described insulated handle lower end is arranged with insulating rubber jacket, and the insulating rubber jacket surface is provided with asperities.Wherein, the asperities on insulation rubber sleeve surface can increase the frictional force between insulation rubber sleeve and the hand, is convenient to grasping.
As preferably, be provided with the bulge loop that turns up that moves on the restriction hand on the described insulating sleeve.Wherein, the bulge loop that turns up can prevent upwards sliding of hand, improves the fail safe of operation.
As preferably, described slide block is provided with spacing hole corresponding to the bolt end of insulated handle upper end.Wherein, the setting of spacing hole can prevent the bolt of handle upper end and the interference fits between the wire clamp seat, thereby has protected the threaded engagement between bolt and the wire clamp seat not to be damaged, and has prolonged useful life of the present invention.
Therefore, it is convenient that the present invention has clamping, characteristics such as can increase work efficiency.
