Embodiment
This embodiment provides a kind of distribution line wire clamp, and the wire clamp that provides of the utility model is provided, and can effectively reduce the difficulty that is connected of wire clamp and alive circuit, simplifies the connection procedure of lead-in wire waiting and alive circuit.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1 and Fig. 2, the distribution line wire clamp that this embodiment provides, comprising:
Wire clamp seat 10, wire clamp seat 10 comprises occipitalia 11 and lower occipitalia 12, between upper occipitalia 11 and lower occipitalia 12, forms activity space, and wire clamp seat 10 is provided with the fixture for fixing lead-in wire waiting;
Be arranged at the movable block 13 in activity space, movable block 13 can move between upper occipitalia 11 and lower occipitalia 12, and is equipped with half groove on the corresponding surface of upper occipitalia 11 and movable block 13, to be formed for the jaws of sandwiched live wire;
Adjusting screw(rod) 14, lower occipitalia 12 is provided with screwed hole, and the rod end of adjusting screw(rod) 14 passes screwed hole, and can drive movable block 13 to move between upper occipitalia 11 and lower occipitalia 12.
So arrange, while adopting distribution line wire clamp that this embodiment provides to connect lead-in wire waiting and alive circuit, first lead-in wire waiting is fixed on wire clamp seat 10 by fixture, then adopt insulation driven rod that wire clamp is delivered on alive circuit by operating personnel, and make in half groove of alive circuit between movable block 13 and upper occipitalia 11, then employing instrument rotation adjusting screw(rod) 14, make adjusting screw(rod) 14 drive movable block 13 to rise, to alive circuit is clamped between upper occipitalia 11 and movable block 13, completed being connected of lead-in wire waiting and alive circuit.When the wire clamp providing by this embodiment connects lead-in wire waiting and alive circuit, simple and quick, effectively improve operating efficiency.
It should be noted that, because adjusting screw(rod) 14 promotes movable block 13 upper and lower displacements at rotation process, and in place the moving past in journey of movable block 13 can not be rotated with adjusting screw(rod) 14.
Therefore, this embodiment can be passed through following manner, in making adjusting screw(rod) 14 can drive movable block 13 upper and lower displacements, avoids movable block 13 along with adjusting screw(rod) 14 rotates.On movable block 13, can be provided with a blind hole, the rod end of adjusting screw(rod) 14 is plugged in blind hole rotationally.
So arrange, because adjusting screw(rod) 14 is to be plugged in rotationally in the blind hole of movable block 13, adjusting screw(rod) 14 is in the time rotating, can not drive movable block 13 to rotate together, and be blind hole due to what arrange on movable block 13, adjusting screw(rod) 14 offsets with the bottom of blind hole, and then can promote movable block 13 and move up.
Certainly, also can pass through alternate manner, in making adjusting screw(rod) 14 can drive movable block 13 upper and lower displacements, avoid movable block 13 along with adjusting screw(rod) 14 rotates.Such as, adjusting screw(rod) 14 can be set to two sections is socketed on together and sleeve pipe in relative rotation, wherein one section of sleeve pipe periphery is provided with external screw thread, it matches with the screwed hole of lower occipitalia 12, another section of sleeve pipe is fixedly connected with movable block 13, these two sections of sleeve pipes can only produce relative rotation, and can not produce and move to axial.So, also can realize in making adjusting screw(rod) 14 can drive movable block 13 upper and lower displacements, avoid movable block 13 along with adjusting screw(rod) 14 rotates.
For the problem that prevents that adjusting screw(rod) 14 and movable block 13 are separated, in the preferred version of this embodiment, the periphery that adjusting screw(rod) 14 is inserted into the part in blind hole can be provided with retaining annular groove, and movable block 13 is fitted with the retaining part 15 being inserted in retaining annular groove.
So arrange, extend in retaining annular groove owing to being plugged in the retaining part 15 of movable block 13, adjusting screw(rod) 14, under the barrier effect of retaining part 15, has been avoided vertically the problem that is separated with movable block 13, and retaining part can not hinder adjusting screw(rod) and rotates.
In addition, in another preferred version of this embodiment, for convenient rotation adjusting screw(rod) 14, the opposite end of the one end that can be connected with movable block 13 at adjusting screw(rod) 14 is provided with operation annulus 16.
In the time that needs raise movable block 13 or lower movable block 13, only need to adopt the action bars with hook, extend in operation annulus 16, and along respective direction rotating operation bar, there is higher operability.
In addition, in this embodiment, can be as following setting for the fixture of fixing lead-in wire waiting.Fixture can be for being arranged at the trip bolt 17 and the compressing tablet that is placed on trip bolt 17 peripheries of wire clamp seat 10, and lead-in wire waiting is pressed between compressing tablet and wire clamp seat 10 by trip bolt 17.
So arrange, in the time screwing trip bolt 17, under the pressure-acting of the nut of screw, compressing tablet can compress lead-in wire waiting.
As preferably, the line ball direction of compressing tablet and the clamp direction of movable block 13 are perpendicular, after lead-in wire waiting is compressed by compressing tablet, with live wire be vertical relation.So arrange, can effectively avoid lead-in wire waiting to contact with the live wire of other phase, and cause the danger of short circuit.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
