Description

wire clamp

technical field

The utility model relates to a device for fixing lines in an electric meter box, in particular to a line clip.

Background technique

The assembly space in the electric energy meter is small, and there are many lines. Generally, cable ties are used to restrain and fix it on the inner wall of the electric energy meter, so as to avoid the mutual winding of circuits, which is not conducive to electrical connection, but the cable tie is a disposable product.

At present, there is a kind of clamp on the market, which includes a base and a top base, both of which are fixed by screws, and the base is fixed on the inner wall of the electric energy meter by screws, and the two are spliced to form a clamping hole. Although this kind of wire clip can play the role of restraining the line, there are problems that when there are too many wires, multiple wire clips are needed, which occupies more assembly space in the electric energy meter; in addition, because the base and the top are directly fixed with screws , When many lines are gathered together, an expansion force will be generated, causing the base and the screw holes on the base to be misaligned, causing inconvenience to assembly.

Utility model content

Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a wire clamp that solves the above problems.

In order to achieve the above object, the utility model provides the following technical solutions:

A wire clamp, including a base and a top base, both of which are fixedly connected by screws, the base is fixed in the electric meter box by screws, the base and the top base are spliced to form a first clamping hole, a second clamping hole and a second clamping hole. Three clamping holes, a positioning hole is provided on the upper end surface of the base, and a positioning rod for cooperating with the positioning hole is protruded on the lower end surface of the top seat.

The utility model is further configured as follows: the outer circular surface of the positioning rod is provided with several convex ribs, and the convex ribs all extend along the axial direction of the positioning rod, and several convex ribs are evenly distributed along the circumferential direction of the positioning rod to form a conical shape.

The utility model is further configured as follows: a plurality of thorns are distributed on the inner side walls of the first thread clamping hole, the second thread clamping hole and the third thread clamping hole.

The utility model is further configured as follows: the second thread clamping hole is arranged between the first thread clamping hole and the third thread clamping hole, and the hole diameter is the largest.

The utility model is further configured as: the top seat is arranged in an arched shape at the position of the second clamping hole.

The utility model is further configured as follows: the bottom wall of the base is provided with reinforcing ribs.

By adopting the above technical scheme, when there are many lines, they can be divided into three groups and placed in the first clamping hole, the second clamping hole and the third clamping hole respectively. After splicing the base and the top seat, the limit rod is inserted into the limit hole to play the role of pre-connection, avoiding the misalignment of the base and the top seat under the action of external force, which is convenient to use.

detailed description

The wire clamp of the present utility model will be further described with reference to the accompanying drawings and embodiments.

A wire clamp, including a base 1 and a top base 2, both of which are fixedly connected by screws, the base 1 is fixed in the electric meter box by screws, the base 1 and the top base 2 are spliced to form a first clamping hole 3, a second The second clamping hole 4 and the third clamping hole 5 are provided with a positioning hole 11 on the upper end surface of the base 1, and a positioning rod 21 for cooperating with the positioning hole 11 is protruded on the lower end surface of the top base 2. When there are many lines, they can be divided into three groups and placed in the first clamping hole 3, the second clamping hole 4 and the third clamping hole 5 respectively, so that multiple clamps are not needed to reduce the occupation of the meter box Space, after the base 1 and the top base 2 are spliced, the limit rod is inserted into the limit hole to play the role of pre-connection, avoiding the misalignment of the base 1 and the top base 2 under the action of external force, which is convenient to use.

The outer circular surface of the positioning rod 21 is provided with several ribs 211 , and the ribs 211 all extend along the axial direction of the positioning rod 21 , and several convex ribs 211 are evenly distributed along the circumference of the positioning rod 21 to form a conical shape. It is convenient to position and insert into the positioning hole 11. The function of the convex rib 211 is to form an interference fit after being inserted into the socket, and the lines placed together will generate expansion force to lift the top seat 2. This structure is convenient for screw assembly .

A plurality of thorns 6 are distributed on the inner walls of the first thread clamping hole 3 , the second thread clamping hole 4 and the third thread clamping hole 5 . It is used to more firmly fix the lines gathered in the clamp hole to prevent the lines from sliding.

The second thread clamping hole 4 is arranged between the first thread clamping hole 3 and the third thread clamping hole 5 and has the largest hole diameter. The top seat 2 is arranged in an arched shape at the position of the second clamping hole 4 . The group with more gathered lines is placed in the second clamping hole 4 in the middle position, and the fixation is more firm, avoiding one end of the top base 2 from tilting, which affects the fixing effect, and the arched line set on the top base 2 can be established The expansion force is greater, which prevents the base 1 from breaking when fixing many lines, and improves the service life of the base 1 .

The bottom wall of the base 1 is provided with reinforcing ribs 7 . In order to save the material of the base 1 and reduce the cost, the inside of the base 1 is set to be hollow, and the reinforcing rib 7 is set along the length direction of the base 1 for increasing the strength of the clamping hole.

The above descriptions are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present utility model all belong to the protection scope of the present utility model. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
