Abstract
The utility model relates to a straight clamp type earth wire, which belongs to the technical field of electrical equipment safety maintenance device. The earth wire consists of an insulation handle and a wire clamp connected on the upper end of the handle. The wire clamp includes a wire clamp seat provided with a post head and two relatively arranged clamp terminals. A spring for pushing away the two clamp terminals is arranged between the two clamp terminals; the lower ends of the two clamp terminals are respectively articulated with the wire clamp seat; the inner side of the lower end of each clamp terminal forms a bevel; a rocker die is arranged at the lower end of the clamp terminal; the rocker die is restricted in the wire clamp seat and can slide along the central line of the two clamp terminals; an action bevel is formed at the two sides of the upper end of the rocker die to match with the bevel in the inner side of the lower end of each clamp terminal; the lower end of the rocker die is matched and connected with screw threads at the upper end of the insulation handle. The straight clamp type earth wire can clamp conveniently and improve the working efficiency, which solves the problems in the prior art that the wire clamp at the conductor end clamps with the conductor inconveniently and that the working efficiency is low, etc.
Description
Technical field
The utility model relates to a kind of straight-clamping type grounding wire, belongs 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 utility model purpose 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 utility model 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 utility model.
Therefore, it is convenient to the utlity model has clamping, characteristics such as can increase work efficiency.
