Abstract

The utility model relates to the technical field of electrics and in particular relates to a support column type lightning arrester. The support column type lightning arrester comprises a cable clamp connected with an electrode lead-out end, wherein the inner side of the cable clamp is provided with a clamping surface; the clamping surface is a smooth plane; the clamping surface is provide with a bulge; or the bulge is a strip-shaped bulge along the wire length direction, or an arc bulge along the direction perpendicular to the length direction or a dotted bulge. The support column type lightning arrester has the advantages that a clamping part has good electric connection, and the using effect is not influenced after long-term use.

Description

A kind of column support type lightning arrester

Technical field

The utility model relates to technical field of electricity, particularly relates to a kind of column support type lightning arrester.

Technical background

The column support type lightning arrester has the wire clamp of connecting electrode exit, in the prior art, the adding of wire clamp, hold the position and have a plurality of conical projections, such projection is called puncture, when adding the wire of holding insulating barrier with wire clamp, the insulating barrier of wire need not be peelled off, puncture directly punctures insulating barrier, like this lightning arrester of connected mode have add hold the position be electrically connected bad, tend to affect its normal use.

Summary of the invention

The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of adding to hold the column support type lightning arrester that the position is electrically connected better, long-time use can not affect result of use.

The technical solution of the utility model is achieved in that a kind of column support type lightning arrester, and it has the wire clamp of connecting electrode exit, and the wire clamp inboard is to add the face of holding, and it is characterized in that: the described face of holding that adds is smooth plane.

Say that further described adding holds mask projection is arranged.

Say that further described projection is the strip projected parts along the conductor length direction.

Perhaps, described projection is the arc-shaped convex of vertical length direction.

Perhaps, described projection is the projection of point-like.

The beneficial effects of the utility model are: such column support type lightning arrester has to add holds the advantage that the position is electrically connected better, long-time use can not affect result of use.

Description of drawings

Fig. 1 is the structural representation of the utility model prior art.

Fig. 2 is the enlarged diagram of A part among Fig. 1.

Fig. 3 is structural representation of the present utility model.

Fig. 4 is the enlarged diagram of B part among Fig. 1.

Wherein: 1, wire clamp 2, add the face of holding 3, the puncture 4, projection.

Specific embodiments:

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, 2, the column support type lightning arrester has the wire clamp 1 of connecting electrode exit, in the prior art, the adding of wire clamp, hold the position and have a plurality of conical projections, such projection is called puncture 3, when adding the wire of holding insulating barrier with wire clamp, the insulating barrier of wire need not be peelled off, puncture directly punctures insulating barrier, and the lightning arrester of such connected mode has to add holds the shortcoming that the position connection is bad, tend to affect normal use.

The utility model is shown in Fig. 3,4, a kind of column support type lightning arrester, the column support type lightning arrester has the wire clamp 1 of connecting electrode exit, wire clamp 1 inboard is to add the face of holding 2, it is characterized in that: the described face of holding that adds is smooth plane, and described smooth plane is for the projection that puncture is arranged, refer to not to grow not only but also the projection of point, but little projection can be arranged, and the projection here just plays with the wire of stripping insulation layer and contacts better, prevents the effect of becoming flexible; Rather than puncturing the effect of insulating barrier, described technical field personnel should be clear.

Say that further described adding holds mask projection is arranged.

Perhaps, described projection is the projection of point-like.

More than several projections be mostly in order to increase hold, to increase the technical scheme of taking electrically contact.

Claims
