Description

TECHNICAL FIELD [0001] The present invention relates to an insulation cap for a wiring crimp terminal and a manufacturing method of the insulation cap, and a manufacturing method of the insulation cap,

The present invention relates to an insulating cap for a wiring crimping terminal, a manufacturing apparatus for the insulating cap and a method of manufacturing the insulating cap, which can identify a warning or a dangerous situation according to the temperature. More particularly, By forming the insulating cap as the first and second insulating layers so as to react with each other according to the exothermic heating temperature, the manager can easily recognize that the warning situation is initiated in the first insulating layer, An insulation cap of a crimp terminal for wiring which enables a warning or a dangerous situation to be identified according to the temperature so that a dangerous situation can be recognized quickly so that the coping can be quickly carried out according to a situation and a manufacturing apparatus of the insulation cap and a manufacturing method of the insulation cap .

Generally, the crimp terminals for wiring are used for electric, electronic products, industrial switchboards or related devices. In order to effectively connect and connect parts, parts, components, power supply or wires and wires, And then pressed and fixed to the molten part.

In this case, an insulation cap was applied to the portion where the sheath of the wire was peeled off and the portion where the crimp terminal was connected, and finished.

Referring to FIG. 1 and FIG. 2, the insulation cap of a conventional wiring crimp terminal will use a wiring crimp terminal 10 for power connection where a three-phase power source is used. The wiring crimping terminal 10 has a cylindrical cable connecting portion 12 and a terminal 14 formed on one end of the cable connecting portion 12 in the form of a flat flat plate. And a connection hole 16 formed therein.

The cable 20 is inserted into the cable connecting portion 12 of the wiring crimp terminal 10 in a state in which the copper wire 22 with a certain portion of the insulating cover 24 at the end is exposed. When the exposed copper wire 22 of the cable 20 is inserted into the cable connecting portion 12, the outer side of the cable connecting portion 12 is pressed through the crimping tool so that the wiring crimping terminal 10 is pressed on the cable 20 So that they are fixedly coupled.

As described above, when the wiring crimping terminal 10 is engaged with and fixed to the copper wire 22 of the cable 10 through the crimping of the cable connecting portion 12, the crimping fixing groove 12a is formed, and the crimping fixing groove 12a The cable 20 is fixed without being detached from the cable connecting portion 12 of the wiring crimp terminal 10 by pressing the outer side of the copper wire 22 on the inner side of the cable connecting portion 12.

After the cable connecting portion 12 is compressed and the wiring crimping terminal 10 is coupled and fixed on the cable 20, the insulating cap 30 is put on the connecting portion of the cable 20 for insulation.

At this time, the insulation cap 30 is displayed in an opaque color to display each phase of the three-phase power source, and is usually displayed in red, blue, and yellow (or white).

This color display allows an operator or an administrator to easily identify the phase of the three-phase power source, thereby making it easier to connect and connect the power source to the power supply line.

However, the conventional insulating cap has an advantage that it can insulate the connection portion between the wiring crimping terminal and the cable. However, there is a risk of fire due to heat generation due to various factors such as a connection failure of the wiring crimping terminal and the cable, However, there is a danger that fire can not be recognized easily.

In order to solve the above-mentioned problem, referring to FIG. 3, a 'terminal for wiring' of the prior art 10-604206 has a flat terminal 210 for directly connecting to a power supply line at one side, A wiring terminal 200 having a cable connection part 220 for allowing the cable 230 to be connected to the inside and being pressed and fixed is provided on the outside of the connection position of the cable connection part 220 and the cable 230, And a color display unit 241 is provided on one side of the insulating cap 240. The color display unit 241 is coated with a paint whose color changes according to a heating state.

In addition, the insulating cap 240 is formed in a tube shape, and is formed by extruding the chlorine scale in a transparent state without adding any dye.

In addition, if the transparent cap is covered on the outside of the connection portion between the cable connection portion 220 and the cable 230, the state of formation of the pressure fixing groove 222 can be directly confirmed without removing the transparent cap.

A color display unit 241 is formed on one side of the transparent cap to identify the image of the three-phase power source. The color display unit 241 is formed in a band shape along the outer periphery of the transparent cap, Yellow < / RTI >

The color display portion 241 may be formed by avoiding the position of the pressure fixing groove 222, and may be formed by attaching a tape, a sheet, or the like.

The color display section 241 uses a thermo-color ('thermo chameleon' or 'chameleon paint').

However, the above-mentioned conventional insulating cap is a method of extruding the plastic, that is, forming a desired product shape continuously by putting the plastic into a mold at a high temperature or a low temperature. When the plastic is molded by an extrusion method, it is formed into a cylindrical shape of the same diameter, In this case, a step is formed due to a difference in diameter between the crimp terminal and the cable, so that the process of inserting the insulation cap is difficult.

In addition, the manufacturing process of attaching a thermo-color to a conventional insulating cap or attaching a tape or a sheet has a problem that the manufacturing efficiency is lowered due to the addition of working water to be performed, and peeling and peeling in the painting or the attached portion is easy There is a problem of losing product reliability that may occur.

In addition, in the conventional insulating cap, there is a problem that the thermo-color is formed in a part of one side, thereby deteriorating the functionality that the operator can not easily recognize the change of the thermo-color according to the temperature change.

Further, since the conventional insulating cap is set at a specific temperature, that is, usually 75 ° C, when heat is generated in the electric wire (or cable) covering the insulating cap and reaches about 65 ° C, It progresses slowly.

In this case, if the temperature is raised by the heating of the electric wire and the manager finds the temperature at the time when the reaction starts from 65 ℃ in thermo-color, the risk of safety accidents There is a problem that the time to take is short and the effect of preventing the occurrence of an accident caused by the heat generation of the electric wire is deteriorated.

Particularly, in precision fields handling precision instruments such as semiconductors, and in research fields such as research laboratories and seed industry fields, overloading, overcurrent, or the like can cause errors in product damage or research data, However, there is a problem in that the insulation cap provided so far has the limitation of a product that can not expect other functions for the purpose of preventing fire.
