Technical Field
The invention relates to the technical field of conductor wire clamps, in particular to a variable-clamping-distance ground wire clamp for a ground wire conductor end clamp.
Background
The grounding wire is a safety tool widely applied to power systems, wherein the portable short-circuit grounding wire is most commonly applied, and the insulating rod is connected with a conductor terminal clamp of the grounding wire to vertically hang the grounding wire to a part needing grounding on a lead. The existing ground wire clamp is an n-shaped clamp, the clamping distance is fixed, and the ground wire clamp with a single clamping distance can only be installed on a wire with a corresponding diameter. When the wire diameter of the wire is too thick, the wire clamp cannot clamp the wire, so that the installation fails; when the wire diameter is too thin, the power of fastener centre gripping wire is lower, and the fastener drops easily to take place. In order to deal with the conducting wires with various wire diameters of the power system, grounding wires with various clamping distances need to be equipped. This not only increases the operation and maintenance cost of power system, and the earth connection that uses multiple clamp distance can bring the puzzlement for the power production work moreover.

In order to achieve the purpose, the invention provides the following technical scheme: a variable-clamping-distance ground wire clamp comprises an A-side wire clamp and a B-side wire clamp, wherein the A-side wire clamp and the B-side wire clamp are both L-shaped, and the A-side wire clamp and the B-side wire clamp are connected through a conductive connecting belt; the short edge of the A-side wire clamp is provided with a fixed plug slot and a fixed rod, the short edge of the B-side wire clamp is provided with a fixed rod slot and a fixed plug, the fixed plug slot is matched with the fixed plug, and the fixed plug slot and the fixed plug are provided with positioning mechanisms; the fixed rod is matched with the fixed rod groove.
Preferably, the positioning mechanism comprises a slot fixing hole, a plug fixing hole and a positioning nail, the slot fixing hole is formed in the fixed plug slot, the plug fixing hole is formed in the fixed plug, and the positioning nail is matched with the slot fixing hole and the plug fixing hole.
Preferably, one side of the side wire clamp A opposite to one side of the side wire clamp B opposite to the side wire clamp A is hinged with a wire clamping column, one end of a spring is mounted on each of the side wire clamp A and the side wire clamp B, and the other end of the spring is mounted on the wire clamping column.
Compared with the prior art, the invention has the beneficial effects that: compared with the existing ground wire clamp, the change of the clamp distance of the clamp can be realized, and the ground wire clamp with the variable clamp distance can be used for the installation work of ground wires with wires of different wire diameters. And the stable clamping effect of the grounding wire with any diameter and size is ensured by the coarse adjustment structure and the fine adjustment structure for setting the distance between the wire clamps on the two sides.
Simultaneously the ground wire clamp of this application has simple structure, small, with low costs, reasonable in design, uses nimble, the characteristics that the practicality is strong, is favorable to generally promoting.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a variable-clamping-distance ground wire clamp comprises an A-side wire clamp 1 and a B-side wire clamp 2, wherein the A-side wire clamp 1 and the B-side wire clamp 2 are both L-shaped, and the A-side wire clamp 1 and the B-side wire clamp 2 are connected through a conductive connecting belt 10, so that the two-side wire clamps are kept at the same potential in use. The short edge of the A-side wire clamp 1 is provided with a fixed plug slot 4 and a fixed rod 5, the short edge of the B-side wire clamp 2 is provided with a fixed rod slot 6 and a fixed plug 3, the fixed plug slot 4 is matched with the fixed plug 3, and the fixed plug slot 4 and the fixed plug 3 are provided with positioning mechanisms for fixing the position of the fixed plug 3 in the fixed plug slot 4. The fixing rod 5 is matched with the fixing rod groove 6, and an auxiliary positioning effect is achieved. Due to the fact that the diameter of the grounding wire is large or small, clamping and positioning of the grounding wire are achieved better, and subsequent installation work is completed. The distance of the fixed plug 3 inserted into the fixed plug slot 4 can be determined according to the diameter of the grounding wire, and the locking between the two positions is completed through a positioning mechanism.
Positioning mechanism includes slot fixed orifices 8, plug fixed orifices 7 and location nail 9, slot fixed orifices 8 are seted up on fixed plug groove 4, plug fixed orifices 7 are seted up on fixed plug 3, and the quantity of plug fixed orifices 7 is a plurality of, and is equidistant setting, location nail 9 cooperates with slot fixed orifices 8 and plug fixed orifices 7. When the positioning pins 9 are inserted into the slot fixing holes 8 and the plug fixing holes 7, the distance between the a-side wire clamp 1 and the B-side wire clamp 2 can be fixed. The positioning nail 9 is T-shaped as a whole, and the diameter of the positioning nail is in clearance fit with the slot fixing hole 8 and the plug fixing hole 7.
Since the plug fixing holes 7 are arranged at equal intervals, the intervals cannot be set too densely, which results in that the grounding wires cannot be perfectly matched with the types and diameters of the grounding wires, and the clamping effect is affected. Therefore, an auxiliary clamping mechanism is required to be provided at the clamping position to further satisfy the fastening of the ground wire. A wire clamping column 11 is hinged to one side, opposite to the side wire clamp 1, of the side wire clamp B2, one end of a spring 12 is installed on the side wire clamp A1 and the side wire clamp B2, the other end of the spring 12 is installed on the wire clamping column 11, and the spring 12 is in a pressing state. When the device is not used, the wire clamping columns 11 on the two sides are in a tight fit state due to the acting force of the spring. When the clamping device is used, the distance between the A-side wire clamp 1 and the B-side wire clamp 2 is roughly adjusted according to the diameter of a grounding wire, and then the wires are further clamped by the wire clamping columns 11 on the two sides, so that the clamping effect is not influenced.
The working principle is as follows: when the connector is used, the distance between the A-side wire clamp 1 and the B-side wire clamp 2 is roughly adjusted according to the wire diameter of the grounding wire, and the positioning nail 9 is inserted into the appropriate plug fixing hole 7. Because the plug fixing holes 7 arranged at intervals are difficult to ensure the clamping force of the wire clamp on the grounding wire with any wire diameter, the wire clamping columns 11 on the two sides can rotate inwards through the elastic effect of the springs 12, the grounding wire is further clamped, and thus any type of grounding wire can be stably clamped.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
