Description

Description INSULATION CAP FOR COMPRESSED WIRE TERMINAL
Technical Field
[1] The present invention relates, in general, to insulation caps for compressed wire terminals and, more particularly, to an insulation cap for a compressed wire terminal which is made of transparent material to make it possible to easily check the condition of a connection between the compressed wire terminal and a cable, and which includes a color indicator to easily distinguish between wire terminals respectively corresponding to each phase of three-phase power. Background Art
[2] Generally, compressed wire terminals are used in electrical and electronic products, industrial distribution boards and related apparatuses. To effectively connect components together, a component to a power supply, or wires to each other, after an end of an insulated covering of a wire is removed to an appropriate length, it is inserted into and reliably fastened to a compressed wire terminal by pressing the terminal. In the initial stage of this art, used is a method in which ends of insulated coverings of wires are removed, exposed conducting parts of the wires are tied to each other, and an insulating tape is wound around the tied portion. This method is still widely used now, and the current regulation requires that insulating tape be wound at least six times when wiring in a building or the like.
[3] Meanwhile, after this, compressed wire terminals have been developed and used.
To use a compressed wire terminal, an end of a covering of a wire is removed and, thereafter, an exposed conducting part of the wire is inserted into a compressing part of the wire terminal, and the compressing part of the wire terminal is forcibly compressed using a pressing tool. Typically, such a compressed wire terminal is used for power connection of a system that uses high pressure three-phase power. Next, the compressed wire terminal and an insulation cap for the compressed wire terminal will be described herein below.
[4] FIG. 1 is a perspective view showing a compressed wire terminal and an insulation cap therefor, according to a conventional technique. FIG. 2 is a sectional view showing the connection of a cable to the compressed wire terminal of FIG. 1.
[5] Typically, the compressed wire terminal 100 shown in FIG. 1 is used for power connection of a system that uses high pressure three-phase power. The compressed wire terminal 100 includes a cable connection part 120, which has a cylindrical shape, and a flat terminal part 110, which extends from one end of the cable connection part 120. Furthermore, as shown in FIG. 2, the cable connection part 120 has in the other end thereof a hollow space 121, into which the cable 130 is inserted.
[6] Meanwhile, an end of a covering 131 of the cable 130 is removed to a predetermined length to expose a copper wire 132. The exposed portion of the copper wire 132 is inserted into the hollow space 121 of the compressed wire terminal 100. As such, after the exposed portion of the copper wire 132 of the cable 130 has been insert ed into the hollow space 121, the cable connection part 120 is pressed using a pressing tool (not shown), so that the compressed wire terminal 100 is reliably fastened to the cable 130.
[7] When the compressed wire terminal 100 is fastened to the cable 130 by pressing the cable connection part 120, as shown in FIG. 2, compressed coupling depressions 122 are formed. Because the outer surface of the copper wire 132 is forcibly compressed by inner surfaces of portions of the cable connection part 120, at which the compressed coupling depressions 122 are formed, the cable 130 can be reliably fastened to the cable connection part 120 without being undesirably removed therefrom.
[8] After the compressed wire terminal 100 has been coupled to the cable 130 by pressing the cable connection part 120, the insulation cap 140 is fitted over a junction between the compressed wire terminal 100 and the cable 130. Here, an opaque color is applied to the insulation cap 140 to indicate each phase of three-phase power. Typical colors are red, yellow or green. Therefore, a user can easily determine the phase of three-phase power by checking the colored insulation cap and connect the three-phase power to the corresponding power supply line.
[9] Furthermore, coupling holes 111 are formed through the terminal part 110 of the compressed wire terminal 100, so that the compressed wire terminal 100 is coupled to a connection member of the power supply line through the coupling holes 111 using bolts.
[10] However, the conventional opaque insulation cap 140 has a problem in that it is difficult to check the connection condition between the compressed wire terminal 100 and the cable 130. In detail, in the case where the terminal 100 and the cable 130 are not completely connected, due to the carelessness of a worker, so that connection failure is induced, for example, although it is preferable that several compressed coupling depressions 122 are formed, if a single or compressed coupling depression 122 is formed, or none are formed, so that connection failure is induced, the cable 130 may be easily removed from the compressed wire terminal 100, and electric shocks or power interruption may result. Furthermore, because the resistance of the defective connection portion is increased, there is a danger of fire due to the generation of heat.
[11] To prevent this, a process of checking the connection conditions between the compression wire terminal 100 and the cable 130 must be conducted. However, the conventional compressed wire terminal is problematic in that, because all insulation caps 140 must be removed to check the connection conditions, it is very difficult to check the connection conditions thoroughly. Disclosure of Invention
Technical Problem
[12] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide an insulation cap for a compressed wire terminal which is made of transparent material and includes a color indicator that is provided on a portion of the insulation cap to indicate the phase of three-phase power, thus making it possible to easily check the condition of a connection between the compressed wire terminal and a cable.
[13] Another object of the present invention is to provide an insulation cap for the compressed wire terminal in which the color indicator is made of paint or tape, the color of which changes in response to a change in temperature, so that the color of the color indicator changes in response to heat generation due to overload or the like to make a user aware of this, thus decreasing the risk of a fire.
Advantageous Effects
[14] As described above, an insulation cap for a compressed wire terminal according to the present invention is made of transparent material, and a color indicator for indicating the phase of three-phase power is provided on a portion of the insulation cap. Therefore, the insulation cap of the present invention has advantages in that it is possible to easily check the condition of a connection between the compressed wire terminal and a cable, as well as having an insulating function.
[15] Furthermore, in the insulation cap for the compressed wire terminal according to the present invention, the color indicator is made of paint or tape, the color of which changes in response to a change of temperature, so that the color of the color indicator changes in response to heat, generated upon overload or the like, to make an administrator aware of this, thus decreasing the risk of a fire.
[16] In addition, a thermal indicator, which is made of paint or tape, the color of which changes in response to a change in temperature, is provided on a terminal part of the compressed wire terminal to indicate whether heat is generated due to an overload or the like such that the administrator can easily be made aware of the heat generation.

[21] FIG. 5 is a sectional view showing the insulation cap provided on the compressed wire terminal according to the present invention. Best Mode for Carrying Out the Invention
[22] In order to accomplish the above objects, the present invention provides an insulation cap for a compressed wire terminal, which has on a first end thereof a planar terminal for connection with a power supply line and has on a second end thereof a cable connection part, into which a cable is inserted, the cable being fastened by pressing the cable connection part. The insulation cap covers the junction between the cable connection part of the compressed wire terminal and the cable. The portion of the insulation cap that covers the junction between the cable connection part of the compressed wire terminal and the cable is transparent, and a color indicator, the color of which changes in response to a change in temperature due to heat generation in the cable, is provided on the portion of the insulation cap that contacts the cable.
[23] Preferably, the color indicator may be made of one among tape, a sheet and paint, the color of which changes in response to a change in temperature due to heat generated in the cable. Here, the color of the color indicator may be one of red (R), green (T) and yellow (S).
[24] Furthermore, the insulation cap may be bent at a boundary between the portion that covers the cable connection part of the compressed wire terminal and the portion that contacts the cable. The diameter of the portion that contact the cable may be less than that of the portion that covers the cable connection part of the compressed wire terminal.
[25] In addition, tape, a sheet or paint, the color of which changes in response to heat generation, may be applied to a terminal part of the compressed wire terminal. Mode for the Invention
[26] Hereinafter, an insulation cap for compressed wire terminals according to a preferred embodiment of the present invention will be described in detail.
[27] FIG. 3 is a perspective view of the insulation cap for compressed wire terminals, according to the present invention. FIG. 4 is a perspective view showing the insulation cap provided on a compressed wire terminal according to the present invention. FIG. 5 is a sectional view showing the insulation cap provided on the compressed wire terminal according to the present invention.
[28] As shown in FIG. 3, the insulation cap 240 of the compressed wire terminal 200 according to the present invention is fitted over a junction between a cable connection part 220 of the compressed wire terminal 200 and a cable 230 to insulate the junction.
[29] The insulation cap 240, which is fitted over the junction between the cable connection part 220 and the cable 230, is formed by extruding vinyl chloride without adding pigment, thus having a transparent tube form. In the case where the transparent insulation cap 240 manufactured by the above method is fitted over the junction between the cable connection part 220 and the cable 230, thanks to transparency thereof, the condition of compressed coupling depressions 222 can be directly observed even without removing the insulation cap 240 from the junction.
[30] Meanwhile, a color indicator 241 for indicating the phase of three-phase power is provided on the insulation cap 240 at a predetermined position, at which the insulation cap 240 contacts the cable 230 coupled to the cable connection part 220. The color indicator 241 is formed in a band shape around the circumferential outer surface of the insulation cap 240 and has a single color, for example, red, yellow or green.
[31] Preferably, the color indicator 241 is provided at a position other than the compressed coupling depressions 222. For example, it is preferable that the color indicator 241 be provided on a front end or a rear end of the insulation cap 240. Furthermore, the insulation cap 240 may be provided by attaching a tape or a sheet and, more preferably, may be provided by applying paint mixed with corresponding pigment.
[32] In detail, it is preferable that the color indicator 241 be provided by applying thermo-color, also known as chameleon paint, to the insulation cap. Then, the color indicator 241 can have a structure such that the color thereof changes when heat is generated upon overload due to connection failure occurring at the junction between the cable connection part 220 and the cable 230.
[33] Therefore, the insulation cap 240 for the compressed wire terminal 200 according to the present invention allows a worker or an administrator to easily observe the connection condition of the cable 230 through the transparent portion of the insulation cap 240 and also to easily determine whether there is safety hazard, such as the risk of a fire due to heat generation, by checking the color indicator 241.
[34] In a brief description of the insulation cap 240 according to the present invention, the portion of the insulation cap 240 that covers the junction between the cable connection part 220 of the compressed wire terminal 200 and the cable 230 is transparent, and the color indicator 241, the color of which changes in response to a change in temperature due to heat generation in the cable 230, is provided on the portion of the insulation cap 240 that directly contacts the cable 230.
[35] Furthermore, the insulation cap 240 having the above-mentioned construction is bent at a boundary between the portion that covers the cable connection part 220 of the compressed wire terminal 200 and the portion that directly contacts the cable 230. Here, the diameter of the portion of the insulation cap 240 that directly contacts the cable 230 is less than that of the portion that covers the cable connection part 220 of the compressed wire terminal 200.
[36] Meanwhile, even if the cable 230 is normally connected to the compressed wire terminal 200, if the terminal part 210 of the compressed wire terminal 200 is incorrectly connected to a power supply line or if the power line is overloaded, the compressed wire terminal 200 generates heat. To enable this to be easily detected, in the present invention, a temperature indicator 250 may be provided on the terminal part 210. The temperature indicator 250 is provided using thermo-color, that is, chameleon paint, in the same manner as that of the color indicator 241 of the insulation cap 240. For this, pigment is added to chameleon paint and, more particularly, red, yellow or green pigment may be used to distinguish the phase of three-phase power.
[37] As such, the temperature indicator 250 may be provided by applying chameleon paint to the terminal part 210, or, alternatively, it may be provided by attaching thermal tape or a thermal sheet to the terminal part 210.
[38] Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention.
