Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

As shown in fig. 1-2, a short circuit indication terminal comprises a metal connector 1 and an insulating sheath 2, wherein the insulating sheath 2 is arranged on the surface of a wire connection part 11 of the metal connector 1, the insulating sheath 2 comprises a regular region 21 and a color-changing region 22, the color-changing region 22 is included in the regular region 21, and the color of the color-changing region 22 can change along with the temperature change.

The short circuit prompting terminal is used in the same way as a conventional wiring terminal, but has a short circuit prompting function. The discoloration region 22 of the insulating sheath 2 of the short circuit indication terminal changes color with temperature change. When the wires are in poor contact or short circuit, the temperature of the wires rises, the temperature of the terminal connected with the wires also rises, the color changing region 22 changes the color accordingly, even if the circuit is in a charged state, a worker can visually observe that a specific wire in a complex circuit has a problem, and the circuit can be overhauled in time. In general, the discolored region 22 is disposed in a ring-like structure at the middle portion of the entire insulating sheath 2, ensuring that the discolored region 22 can be visually observed through 360 degrees.

As shown in fig. 3-4, the color-shifting region 22 is also preferably divided into a first color-shifting region 221 and a second color-shifting region 222. Wherein the color change of the first color-changing region 221 has irreversibility, the color of the first color-changing region 221 changes after the circuit generates high temperature, and the color of the first color-changing region 221 is not restored even if the temperature is reduced. The color change of the second discoloring region 222 is reversible, and the color of the second discoloring region 222 changes after the circuit generates high temperature, and the color of the second discoloring region 222 returns to the original color after the temperature is reduced.

The effect that the color changes and has irreversible first color-changing region 221 can be embodied, when the staff patrols and examines the switch board, if the color change is carried out to first color-changing region 221 on some terminals, the color is different from the initial color, the wire that can judge this terminal has a problem, can influence the operation of whole circuit, but has not yet embodied in practice, should make the prevention in advance, or in time handle this wire.

The second discoloration region 222, which has a reversible color change, may be used in that the second discoloration region 222 may only display a real-time failed line, and problems generated at other times may not be displayed. When the circuit discovers the trouble suddenly, the colour of second discoloration district 222 on the terminal through observing which wire has produced the change, and the colour is different with initial colour, can judge the wire of this terminal for the circuit that leads to this trouble, can find trouble circuit in time and overhaul.

Wherein, the patent 201610459300.5 and the patent 201210353784.7 respectively describe one implementation method of the first color-changing region 221 and the second color-changing region 222 with irreversible color change and reversible color change, the color selection can be adjusted by adjusting the ratio of each component, and the selection of the color and the rate of change of the color are different and need to be adjusted according to different places to be used, so the detailed description is omitted here.

Furthermore, in order not to confuse the worker with the first and second

discolored regions

221 and 222, the first and second

discolored regions

221 and 222 cannot be recognized. The first and second

discolored regions

221 and 222 may be marked with identification marks 23 on upper or lower sides thereof, and the identification marks 23 may be in fonts or other symbols. Or the colors used between the regular area 21 and the first and second

discoloring areas

221 and 222 are different, and in general, the regular area 21 uses colorless and transparent as the main color tone, and the discoloring area 22 uses other colors which are not colorless and transparent as the main color tone. On the basis of this, the regular color and the color after color change are different between the first color-changing region 221 and the second color-changing region 222.

The above embodiments of the present invention are not right the utility model discloses the limited protection scope, the utility model discloses an embodiment is not limited to this, all kinds of basis according to the above-mentioned of the utility model discloses an under the above-mentioned basic technical thought prerequisite of the utility model, right according to ordinary technical knowledge and the conventional means in this field the modification, replacement or the change of other multiple forms that above-mentioned structure made all should fall within the protection scope of the utility model.
