Abstract

PURPOSE: A sleeve for connecting an electric wire is provided to adhere closely the electric wire on an inner face of the sleeve by forming a concavo-convex portion on an inner face of the sleeve. CONSTITUTION: A sleeve for connecting an electric wire includes a main body(10), a median strip(11), and a plurality of receiving parts(12,12'). The receiving parts(12,12') are used for receiving or storing the electric wire. The receiving parts are formed at both sides of the median strip(11). A concavo-convex portion or a saw-tooth portion is formed on each surface(13) of inner bases of the receiving part(12,12').

Description

Sleeve for connecting and coupling power lines

The present invention relates to a sleeve for electric wire connection. More specifically, the complete connection between the wires can increase the connection rate and mechanical strength, improve the construction method of the joints, eliminate the causes of failures, and prevent economic losses. The present invention relates to a sleeve for wire connection connection of a prismatic concave-convex model that can improve environment and distribution quality.

Conventionally disclosed wire connecting connectors include "sleeve for connecting wires" of Korean Patent Application Publication No. 96-32801 [Fig. 4A], "sleeve for connecting low voltage wires" of Korean Utility Model Registration No. 95-1454. 4b], "Low-voltage wire branching sleeve" of the Korean Utility Model Registration No. 95-3109 (Fig. 4c), and "Sleeving for wire connection" of the Korean Utility Model Registration No. 20-0158019 [Fig. 4d], etc. This was introduced.

According to this conventional technique, the inside of the sleeve connecting the electric wires, that is, the electric wire connecting tube that surrounds and connects the electric wires is mostly flat, and the external model of the electric wires to be connected is a crimped concave-convex type twisted with stranded wire. Therefore, when inserting and compressing the wire inside the sleeve, the pressure inside the sleeve is tightened uniformly, so that the element wire and the inner surface of the sleeve come into contact with each other, and the body of the element is completely bound, but there is a gap between the gap between the element wire and the inner sleeve. .

Therefore, when excessive tensile force is applied to the wires connected to both ends of the wire connector, such voids cause overheating of the wire connection points and poor connection of the joints due to the corona phenomenon, wire breakage, and corrosion of the wires, causing a power failure. In particular, the connection defect of the joint is a cause of shortening the wire usage period, causing frequent repair work and economic loss.

Accordingly, the present inventors have intensively researched to solve the problems of the conventional sleeves for wire connection, and as a result of forming a tooth type of the preferential type as opposed to the external model of the wire on the inner surface of the sleeve, It has now been found that the wires can be brought into close contact with the wires, leading to the present invention.

The present invention can improve the connection rate and mechanical strength by the complete connection between the wires, improve the construction method of the joints, eliminate the cause of failure, prevent economic losses, work environment and It is an object of the present invention to provide a sleeve for a wire connection connection of a priority type irregularities that can improve the distribution quality.

The straight or branched sleeve for electric wire connection connection of the present invention is characterized in that a preferential concave-convex or serrated model is formed along the axial direction of the sleeve on the surface of the electric wire inner member base.

1 is a perspective view of a branch sleeve for a wire connection connection according to a first embodiment of the present invention, as shown in Figure 1, the sleeve body 10 for a wire connection connection is a center separator 11 The wire receiving parts (12, 12 ') that can wrap the wire around the left and right are located.

According to the present invention, the inner base surface 13 of the wire receiving portions 12 and 12 'is formed with a wire-separated priority type irregularities or sawtooth models up to both ends along the axial direction of the sleeve body 11. have.

Figure 2 of the accompanying drawings is a perspective view of a branch sleeve for connecting the wire connection according to a second embodiment of the present invention, according to Figure 2, the wire accommodating to wrap the wire in the left and right without a central separator as in Figure 1 The portions 22, 22 'are open to face in opposite directions, and the inner base surface 23 of the wire receiving portions 22, 22' has a preferred type of concave-convex or serrated model for wire fastening. Along the axial direction of the sleeve main body 20, it is formed to both front-end | tips.

3 of the accompanying drawings shows a perspective view of a straight sleeve for connecting a wire connection according to a third embodiment of the present invention, according to Figure 3 the inside of the straight sleeve body 30 having one wire receiving portion 32 Priority concave-convex or jagged for wire fastening is formed on both sides of the base surface 33 along the axial direction of the sleeve body 30.

According to the present invention, the preferred model is formed on the inner surface of the sleeve body by forming a preferred model on the inner surface of the sleeve body as opposed to the external model of the wire, and the preferred tooth model formed on the inner surface of the wire sleeve even during compression work. It eliminates the convenience of construction and the cause of the line failure by preventing the gap between the wire connection connector or the wire connection connector from expanding due to the elasticity of the wire connection connector or the wire and the gap caused by the gap between the wires after compression. There is an effect that can prevent economic losses.
