Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the compression sleeve for preventing the separation of the wire according to the present invention and a method of manufacturing the same.

The crimping sleeve 10, 20, and 30 for preventing separation of the electric wire according to the present invention includes an outer sleeve in which a space in which the electric wire is accommodated is formed, and the inner surface of the outer sleeve has a predetermined depth. A binding groove (11a) (21a) (21a') (31a) is formed to surround the electric wire.

Alternatively, the crimping sleeves 10, 20, and 30 of the present invention include an outer sleeve 11, 21, 21', 31 in which a space in which an electric wire is accommodated is formed, and the outer sleeve 11 ( 21) (21') (31) is formed in a shape that surrounds the electric wire by reinforcing the strength, and is inserted into the outer sleeve (11) (21) (21') (31), the inner support (12) ( 22) (22') (32).

First, in an example in which a binding groove (11a) (21a) (21a') (31a) is formed on the inner surface of the outer sleeve (11) (21) (21') (31) to wrap the wire to a predetermined depth. It will be described.

The outer sleeves 11, 21, 21', 31 form the outer shape of the compression sleeves 10, 20, 30. A space for accommodating electric wires is formed inside the outer sleeve 11, 21, 21 ′, and 31 so that the electric wires are connected to each other therein. The outer sleeves 11, 21, 21 ′ and 31 may be formed in various shapes depending on the shape of the wires connected to each other and the portion to which the compression sleeves 10, 20, and 30 are fixed.

The binding grooves 11a, 21a, 21a', 31a are formed at a predetermined depth on the inner side of the outer sleeve 11, 21, 21', 31. Since the inner surface of the outer sleeve 11, 21, 21', 31 becomes a discontinuous surface by the binding grooves 11a, 21a, 21a', 31a, the crimping sleeve of the present invention ( 10) When the wire is inserted into the (20) (30), the portion where the binding grooves (11a) (21a) (21a') (31a) are not formed presses the side of the wire, thereby further improving the binding force.

The binding groove 11a is formed along the inner surface of the outer sleeve 11 in a direction perpendicular to the electric wire inserted therein. In addition, the binding groove (11a) is formed repeatedly at intervals along the longitudinal direction of the outer sleeve (11).

The outer sleeve 11 presses the side surface of the electric wire with the inner side thereof, and the binding force of the portion where the coupling groove 11a is not formed is relatively strong, thereby preventing separation of the electric wire.

The binding groove 21a may be formed along the inner surface of the outer sleeve 21 in a direction perpendicular to the electric wire, and is repeatedly formed along the length direction of the outer sleeve 21.

Similarly, the outer sleeve 21 presses the side surface of the electric wire with the inner side thereof, but since the binding force of the portion where the coupling groove 21a is not formed is relatively strong, the separation of the electric wire is prevented.

Meanwhile, as shown in FIG. 6, a binding groove 21a ′ formed on an inner surface of the outer sleeve 21 ′ may be formed in a spiral shape.

The outer sleeve 21 ′ basically has a shape as described in FIG. 5, but the binding groove 21a ′ has a spiral shape.

12 to 14 illustrate an embodiment of a method of manufacturing a crimping sleeve for preventing separation of an electric wire according to the present invention.

The manufacturing method of the compression sleeve according to the present embodiment includes an outer sleeve preparation step (S110) of mounting an outer sleeve to an extrusion die, and an inner support preparation step of preparing an inner support 12 to be inserted into the outer sleeve 11 (S120) and an extrusion step (S130) of extruding the inner support 12 and the outer sleeve 11 through the extrusion die.

In the outer sleeve preparation step (S110), the outer sleeve 11 is mounted on one side of the extrusion die 51. The outer sleeve 11 in the outer sleeve preparation step (S110) is formed in a cylindrical structure, and the extrusion die 51 is mounted on one side.

In the step of preparing the inner support (S120), the inner support 12 to be inserted into the outer sleeve 11 is prepared. The inner support 12 may be disposed in the same direction as the outer sleeve 11 with respect to the extrusion die 51.

In the extrusion step (S130), the outer sleeve 11 and the inner support 12 are extruded using the extrusion die 51. A double compression cylinder 52 may be applied to pressurize the outer sleeve 11 and the inner support 12. The double compression cylinder 52 is arranged so that the internal supports 12 are spaced apart from the inside of the extruded body (semi-finished product of the compression sleeve) discharged from the extrusion die 51 (this is the internal support in the completed compression sleeve). It is the same as those arranged at intervals), and the compression speed is adjusted using the volume ratio.

In addition, in the extrusion step (S130), an extrusion device such as an extrusion die 51 is extruded while maintaining a predetermined temperature. For example, when the outer sleeve 11 is made of aluminum or its alloy, and the inner support 12 is made of copper or its alloy, it is extruded while maintaining 450°C to 500°C.

In the heat treatment step (S140), the extruded body that has passed through the extrusion step (S130) is heated to a predetermined temperature through a heat treatment device 61 to perform heat treatment. For example, when the outer sleeve 11 is aluminum or an alloy thereof, and the inner support 12 is copper or an alloy thereof, it may be 500°C to 600°C.

Thereafter, the extruded body is cut to a predetermined length through the cutter 71 (S150), and then finished to complete the compression sleeve 10.

When the melting point of the inner support 12 is higher than the outer sleeve 11 and extrusion is impossible, the compression sleeve 10 may be manufactured by the method shown in FIG. 15. For example, when the outer sleeve 11 is made of copper or an alloy thereof, and the inner support 12 is made of aluminum or an alloy thereof, extrusion is not possible, so a method as shown in FIG. 10) is prepared.

The outer sleeve preparation step (S210) prepares the outer sleeve 11. Unlike manufacturing a compression sleeve by extrusion, in this embodiment, an outer sleeve 11 formed in a plate shape is prepared.

In the step of forming a support groove (S220), an insertion groove 41a into which the inner support 12 is to be inserted is formed in the outer sleeve 11. A plurality of insertion grooves 41a are formed at intervals on one side of the outer sleeve 11 using a tapping machine or the like (see FIG. 16).

In the step of inserting the inner support (S230), the inner support 12 is inserted into the insertion groove 41a. By inserting the inner support 12 into the insertion groove 41a and performing high-temperature pressure welding, the inner support 12 may be inserted into the insertion groove 41a (see FIG. 17).

Thereafter, in the bending step (S240), the end of the outer sleeve 11 into which the inner support 12 is inserted is bent to form a compression sleeve having a desired shape.
