Embodiment
Embodiment 1
Use Fig. 1-3 that the bindiny mechanism of the terminal board of present embodiment 1 is described.
At first, use the equipment of this arrangements of terminal to constitute as shown in Figure 1, the formation of this equipment, operation and prior art are basic identical, at this moment omit explanation.
In addition, as shown in Figure 2, here used arrangements of terminal (platform) is provided with the terminal 21-24 of outside wiring operator in order to connecting wiring, corresponding to these terminals, in indoor terminal board 9 and outdoor terminal board 13, be provided with the power line splicing ear 21a as the internal wiring side terminal, the sub-22a of signal wire connecting end, neutral line splicing ear 23a and the ground wire splicing ear 24a that is connected to indoor and outdoor control basal plate 10,14 respectively through dividing plate 25, and, also be provided with the dividing plate (next door wall) 26 of side between each splicing ear that is used to divide terminal board 9,13.
In addition, the wiring 11b that is connected on the terminal board 9,13 for example is made of power line 16, holding wire 17, the neutral line 18 and 194 distributions of ground wire, as Fig. 4 or shown in Figure 5, in these wirings 11b, except that ground connection wiring 19, its terminal 20 all forms bar-shaped, in the terminal of ground wire 19 assembling Y word or circular terminal to form Y word or circular shape.In addition, the color of each terminal is corresponding on the color of these wirings and the terminal board.
Below, the terminal board of formation like this and the operation that is connected of wiring are described.
At first, the bar-shaped terminal 20 of power line 16, holding wire 17 and the neutral line 18 is inserted after the wiring insertion mouth 29 of same color on each terminal board 9,13, the fastening screw 30 that is connected with terminal crimping plate 31, thus make each terminal clamp between terminal crimping plate and packing ring.
At this moment, the ground connection wiring 19 that has Y word or circular terminal in terminal is not inserted mouth 29 because its terminal is inserted wiring, so take out the screw 30 that is connected with terminal crimping plate 31 in the terminal 24 of the terminal board that never having connects up inserts mouth 29, and after the terminal with screw 30 insertion Y words or circular terminal, the fastening screw 30 that is connected with terminal crimping plate 31, thus ground terminal is clipped between terminal crimping plate and the packing ring.
As mentioned above, make each wiring and each splicing ear of terminal board have same color accordingly, thereby can incorrect link not connect up, simultaneously, only the terminal at ground wire is provided with Y word or circular terminal, if do not take out the terminal crimping plate and the screw of terminal board, just ground wire can't be connected on the terminal board, in other words, owing to ground wire can not be assemblied on other terminal of terminal board, the operation so can correctly, positively connect up, thereby the terminal board bindiny mechanism that can obtain correctly, positively to assemble ground wire.
In addition, as shown in Figure 3, this moment is also at terminal board 9,13 wiring inserting side wall is provided with dividing plate 28, have on this dividing plate bar-shaped terminal 20 to be inserted into and connect power line 16, each terminal board 9 of the holding wire 17 and the neutral line 18,13 power connector end 21, mouth 29 is inserted in the wiring of the wiring inserting side of signal connecting terminal 22 and neutral line splicing ear 23, inaccessible wiring inserting surface between the dividing plate 26 of each splicing ear, if do not insert mouth 29 by wiring, just can not carry out the connection of each wiring, thereby on each splicing ear that each wiring is connected in terminal board the time, when especially ground wire 19 being connected on the splicing ear except that earth terminal of terminal board, even take out terminal crimping plate 31 and screw 30 each splicing ear beyond earth terminal, also can not insert mouthful 29 Y words that insert or circular terminal etc. from wiring because in the terminal of ground wire 19, be equipped with, and can not insert mouthful 29 insertion assembling ground wires 19 from wiring, therefore, compare with the terminal board structure of Fig. 2, can obtain further to assemble really the terminal board bindiny mechanism of ground wire.
Bindiny mechanism according to terminal board of the present invention, possess: comprise many wirings of ground wire, with terminal board with each the splicing ear portion that is connected these wirings respectively, it is characterized in that: on above-mentioned terminal board, the wiring of the splicing ear portion except that earth terminal portion is inserted sidewall and is provided with the insertion mouth that above-mentioned wiring terminal is passed through, in above-mentioned ground terminal Y word or circular terminal are installed simultaneously, above-mentioned ground wire can not be connected in above-mentioned each splicing ear portion except that earth terminal portion through above-mentioned insertion mouth, so can really ground wire be connected in the earth terminal portion of terminal board, thus can provide a kind of can be correct, really the operation of connecting up, especially the terminal board bindiny mechanism of high reliability that can the incorrect link ground wire.
In addition, the wiring inserting side wall of above-mentioned terminal board has sealed the wiring inserting surface between the wall of next door, described next door wall is used to divide the side of each splicing ear except that above-mentioned earth terminal portion, thus can obtain not can the incorrect link ground wire the higher terminal board bindiny mechanism of reliability.
In addition, respectively with each splicing ear portion of the above-mentioned terminal board of color differentiating, also distinguishing above-mentioned each wiring corresponding to the color of this color, thus can discern more clearly, and obtain can be more accurate, the connect up higher terminal board bindiny mechanism of reliability of operation positively.
In addition, above-mentioned terminal board bindiny mechanism is used for power-supply wiring mixes the wiring connecting portion that exists with signal routing, so can clearly be distinguished also can correctly, positively the connect up high reliability equipment of operation of power-supply wiring and signal routing.
