Detachable insulation cover for terminal insulation {SEPARABLE INSULATING COVER FOR INSULATING TERMINAL}

The present invention relates to a removable insulation cover for terminal insulation, and more particularly, in a cable assembly having a connection portion electrically connected to each other, a removable insulation cover for terminal insulation that can be insulated and covered in a short time after the terminal assembly. It is about.

In general, a cable used as a feed line for a high-voltage line of several tens of kilovolts (KV) is manufactured by being coated with a resin of an insulating material and a semiconducting material for the purpose of electrical insulation and equal distribution of voltage and shielding.

These cables are connected in a branch or straight line according to the direction of the electrical path to form a line. In this case, since most cable accidents occur mainly at the connections between the cables, it is necessary to be able to completely insulate these connections, and to require a structure that can be reworked in the future.

There is a need for a more complete implementation of insulating materials that can be insulated.

In this connection member, a conventional termination member will be described.

The conventional cable termination member is composed of a detachable connector or an integral connector.

That is, the direction in which the grooves 412a are formed and the direction in which the protrusion lines 422a are formed may be perpendicular to each other.

In addition, the protrusion lines 322a may be formed to extend a predetermined length to the inner circumferential surface of the second inclined body 421.

Next, the method of coupling and the operation and effects of the terminal insulation removable insulation cover for the terminal insulation removable insulation cover of the present invention is configured as described above is adopted by the cable connection.

1 to 5, the pair of cables 50 and 50 'are disposed to face each other. Here, the cable of one side has a connecting end 51 of a metal material that is not coated at one end, the connecting end 51 is formed with a connection hole (51a). The cable 50 'on the other side has a connecting end 51' made of a metal material not coated at one end thereof, and a connecting hole 51'a is formed in the connecting end 51 '.
As shown in FIG. 3, the connection end 51 of the cable 50 on one side and the connection end 51 'of the cable 50' on the other side overlap each other. At this time, the connection hole 51'a formed in the connection hole 51'a formed in the connection end 51 'of the cable 50' of one side and the connection end 51 'of the cable 50' of the other side 50'a. ) Also overlap each other. Therefore, the overlapped connecting ends 51 and 51 'may be electrically connected to each other by winding a plurality of times with an electric wire (not shown).

Therefore, the connection parts of the two cables 50 and 50 ', to which the connection ends 51 and 51' are connected, are exposed to the outside.

Subsequently, the cable connection part may be insulated from the outside by using the insulation cover of the present invention.

As shown in Figure 1, the cover body 100 according to the present invention can be opened so that its interior is exposed. That is, the first cover body 110 and the second cover body 120 may be separated from each other by using the connecting portion 130 as a hinge axis.

The cable 50 connection part may be located in an inner space of the cover body 100.

Subsequently, the cover body 100 may be retracted to surround the connection portion of the cable 50. That is, the first cover body 110 and the second cover body 120 may be retracted from each other using the connecting portion 130 as a hinge axis. At this time, by the connecting groove 131 formed on the inner surface of the connecting portion 130 may guide the rotation operation of the first and second cover body (110, 120) according to the collapse.

Accordingly, the first and second cover bodies 110 and 120 may have a cylindrical shape in the inner space thereof, and the cable 50 connection portion may be located in the inner space.

Subsequently, the first and second cover bodies 110 and 120 may be coupled to each other by the coupling part 300.

In more detail, the coupling protrusions 322 formed to protrude from the second coupling part 320 are fitted into the coupling grooves 312 formed in the first coupling part 310, respectively. The two cover bodies 110 and 120 may be coupled to each other.

At this time, the protrusion 322b of the coupling protrusion 322 is formed so that the diameter (D2) is larger than the diameter (D1) of the coupling hole 312, it should be fitted to the coupling hole 312 in the interference fit method. do. In addition, when applying a fluid such as viscous oil to the protrusion body 322a and the protrusion 322b, the protrusion 322b may be more easily fitted into the coupling hole 312.

In addition, since the protrusion 322b has a configuration in which the outer diameter gradually increases along its downward direction from the top thereof as shown by the arrow, and the bottom thereof forms a flat surface, the protrusion 322b is the coupling hole 312. When fitted in, the flat surface of the projection 322b is fixed across the peripheral surface of the coupling hole 312.

Accordingly, the coupling protrusions 322 are fitted into and fixed to the coupling holes 312 in this manner, so that the first and second surfaces 1 and 2 of the first and second cover bodies 110 and 120 are fixed. The surface ② ′ may be in contact with each other, and the inner surfaces of the first and second coupling bodies 310 and 320 may be in close contact with each other.

Accordingly, the connection portion of the cable 50 may be disposed inside the first and second cover bodies 110 and 120 to be insulated from the outside.

On the other hand, the first extension portion 410 of one end of the cover body 100 of the present invention can grip the outer surface of one end of the cable 50, the second extension portion 420 to the end of the cable 50 The outer surface of the termination member 500 that can be provided can be gripped. Here, the termination member 500 is larger than the diameter of the cable 50.

First, since the first extension body 412 of the first extension portion 410 has an inner diameter smaller than that of the cover body 100, the first extension body 412 is in close contact with the outer surface of the cable 50 to close one end of the cable 50. Can be fixed In addition, since the first inclined body 411 of the first extension part 410 has an inner diameter that gradually decreases from the inner diameter of the cover body 100, the cable 50 has one end to be bent to provide a correction space. can do.

In addition, since the groove 412a having a corrugated pipe shape is formed on the inner circumferential surface of the first extension body 412, one outer surface of the cable 50 may be vacuum absorbed.

Next, the second extension body 422 of the second extension portion 420 is in close contact with the outer surface of the terminal connecting member 500 provided at the end of the cable 50 because the inner diameter is formed larger than the inner diameter of the cover body 100. The terminal connecting member 50 can be fixed. In addition, since the inner diameter of the second inclined body 422 of the second extension part 420 is gradually increased from the inner diameter of the cover body 100, one end of the termination member 500 is no longer covered by the cover body ( It may be guided so as not to be drawn into the interior of the 100).

In addition, since the plurality of protrusion lines 422a along the central axis C of the cover body 100 protrude from the inner circumferential surface of the second extension body 422, the outer surface of the termination connecting member 500 is easily formed. In addition, the outer surface of the termination member 500 may be vacuum-adsorbed.

On the other hand, the protrusion lines 422a and the corrugated pipe-shaped grooves 412a are formed in a direction perpendicular to each other, such that the cable 50 passing through the inner space of the cover body 100 is along the axial direction thereof. One end of the cable 50 and one end of the termination member 500 can be easily fixed so as not to flow.
