Abstract
The utility model discloses a clip of hook-typed earth conductive wire end, which is used for short circuit earth in maintenance of high voltage electric circuit. The utility model comprises a hook body, a lever-typed inner tongue with a pressure arm, a soft copper wire connecting hole, and a pressure mechanism composed of a pressure rear seat, a pressure spring, and a draw rod. One end of the draw rod is an insulated operating rod joint. The utility model adopts the lever-typed inner tongue with a pressure arm and the pressure rear seat which is directly drawn by the draw rod; thus, when the utility model is used, a clip can be conveniently made to loosen a high voltage conducting wire, and the clip can be conveniently discharged from the high voltage conducting wire.
Description
The safety protective tools of using when the utility model relates to a kind of high-voltage electrical apparatus line maintenance, specifically a kind of conductor wire end chuck of portable short-circuit grounding wire.
The short-circuit grounding wire conductor wire end chuck that uses mainly contains two kinds at present, and a kind of is Luo line push type, and a kind of is hook type.Luo line pusher-type chuck is made up of conductor metal frame and its inner live metal plate of an openings at one side, have annealed copper wire on the framework and connect the hole, be connected with the Luo bar on the live metal plate, the Luo bar passes framework as the insulating bar joint, rotate insulating bar during use, advance the live metal plate to clamp lead with framework by the Luo line; The hook type chuck is made up of coupler body and interior tongue, have annealed copper wire on the coupler body and connect hole and insulating bar joint, interior tongue has the pressure mechanism of a spring as interior tongue behind, during use, leans on the pressure of the internal tongue of spring to make interior tongue clamp lead with coupler body.Though more than two kinds of chucks can satisfy instructions for use, but all there is a weak point, be exactly in use, chuck is installed and removed cumbersome on lead, particularly will be when lead disassemble, chuck is difficult to unclamp lead, and human body must maintain a certain distance with aerial lead, and aerial lead has rocking to a certain degree again in unloading process, so dismounting difficulty relatively.
The purpose of this utility model provides a kind of chuck, and it will can make it unclamp lead, thereby can use more easily when lead disassemble with comparalive ease.
Technical solution of the present utility model is: on the basis of existing hook type chuck, the interior tongue formation pressure arm that extends back, tongue becomes the interior tongue of lever in making, and pressure arm has a rear end face; Set pressure mechanism is made up of pressure back seat, compression spring and pull bar, and an end of pull bar links to each other with the pressure back seat, and the other end is the insulating bar joint; Can make the pressure back seat move to the rear end face of interior tongue pressure arm backward by insulating bar pulling pull bar.During use, coupler body hooks lead, and one draws insulating bar, and between tongue and the coupler body, at this moment, the pressure back seat was under the effect of compression spring in lead entered, and tongue pressure arm in pressing makes interior tongue clamping wire; In the time will dismantling, by insulating bar pulling pull bar, make mobile backward the rear end face of pressure back seat up to interior tongue pressure arm, at this moment, interior tongue is under the effect of lead, and its pressure arm is to the coupler body inner rotation, releasing lever, the rear end face of tongue pressure arm in the pressure back seat just withstands, thus tongue opens in making, and so just can take off chuck from lead.
Owing to adopted the pressure back seat of interior tongue of lever and pull bar direct pull in the above-mentioned solution, can make chuck unclamp lead very easily, unload lower chuck from lead easily.
The utility model is described in further detail below in conjunction with accompanying drawing.
Sectional arrangement drawing when Fig. 1 is the utility model clamping wire;
Fig. 2 is the sectional arrangement drawing of the utility model when interior tongue opens;
Fig. 3 is a back of the present utility model schematic diagram;
Fig. 4 is a coupler body schematic diagram of the present utility model.
Shown in Fig. 1 to 4, the utility model comprises that coupler body (6), interior tongue (7), annealed copper wire connect hole (9), insulating bar joint and pressure mechanism, interior tongue (7) has a pressure arm that extends back (4), pressure arm (4) has a rear end face (12), pressure mechanism is made up of pressure back seat (3), compression spring (2), pull bar (1), and an end of pull bar (1) is connected with pressure back seat (3), the other end is the insulating bar joint; Compression spring (2) is set on the pull bar (1); Pressure back seat (3) has alignment pin (10), the corresponding with it location cotter way (13) that has on coupler body (6); Interior tongue (7) is connected with coupler body (6) by pin (11), and interior tongue (7) can rotate within the specific limits around pin (11).
As shown in Figure 1, after chuck sandwiched lead (8), pressure back seat (3) pressed interior tongue (7) pressure arm (4) under the effect of compression spring (2), make interior tongue (7) clamping wire (8).
When spurring pull bar (1) by insulating bar, pressure back seat (3) moves backward, rear end face (12) up to interior tongue (7) pressure arm (4), at this moment interior tongue (7) is under the effect of lead, its pressure arm (4) is to coupler body (6) inner rotation, and releasing lever (1), pressure back seat (3) just withstand the rear end face (12) of interior tongue (7) pressure arm (4), as shown in Figure 2, thus interior tongue (7) is opened.
When pressure back seat (3) moves to the rear end face (12) of interior tongue (7) pressure arm (4) backward, for the pressure arm (4) that uses interior tongue (7) reliably to coupler body (6) inner rotation, a rotation spring (5) can be set.
Claims (3)
1, the earthy hook type earth connection conductor wire end chuck of short circuit during a kind of high-voltage electrical apparatus line maintenance, comprise coupler body (6), interior tongue (7), pressure mechanism, annealed copper wire connects hole (9), the insulating bar joint, it is characterized in that: interior tongue (7) also has a pressure arm that extends back (4), pressure arm (4) has a rear end face (12), pressure mechanism is by pressure back seat (3), compression spring (2), pull bar (1) is formed, one end of pull bar (1) is connected with pressure back seat (3), the other end is the insulating bar joint, and pressure back seat (3) can move to the rear end face (12) of pressure arm (4) backward under the drive of pull bar (1).
2, hook type earth connection conductor wire end chuck according to claim 1 is characterized in that: an alignment pin (10) is arranged, the corresponding with it location cotter way (13) that has on coupler body (6) on the pressure back seat (3).
3, hook type earth connection conductor wire end chuck according to claim 1 and 2, it is characterized in that: compression spring (2) is set on the pull bar (1).
