Description
Technical field
The utility model relates to plant equipment constructing technology in the communications field, is specifically related to be used for the AC distribution junction box of communication cabinet.
Background technology
In communication, IT and field of broadcast televisions, because the needs of system design and equipment control, equipment that some are crucial such as minicomputer, server, industrial computer, router etc. all are installed in the rack.The said equipment adopts Alternating Current Power Supply usually, the alternating current of AC power need be introduced rack and distribute to equipment in the rack.Common way is, alternating current at first passes through distribution or the branch means in the rack, and then distributes to the electric power plug socket in the rack, gives power devices in the rack by insert row at last.Therefore, distribution or branch means are very important in the rack power supply.
The sub power distribution line apparatus is a kind of branch means of box structure as shown in Figure 1 in the existing rack.
There is following shortcoming in sub power distribution line apparatus shown in Figure 1:
1, the equipment mounting means in this kind Unit Installation mode and the rack is identical, will take effective installing space of rack in rack, need could firmly be installed in the rack by slideway simultaneously.
2, generally speaking, the relations of distribution of power supply input way, power supply output way and the input and output of this device are fixed, be designed to 1 the tunnel such as certain device and import corresponding 1 tunnel output, just be difficult to become one the tunnel and import corresponding 2 tunnel outputs, import corresponding 2 tunnel outputs unless change one one the tunnel again.Therefore can't increase or reduce the input way flexibly according to what of rack internal configurations equipment, also can't increase or reduce the input way of power supply to the variation of power supply back-up demand according to equipment in the rack.
3, after the rack installation, the rack rear portion can be stopped by cable and dependency structure spare.Because this kind sub power distribution line apparatus is the same with other equipment all to be installed in rack inside, so operation and maintenance all compares difficulty.
The utility model content
The utility model provides a kind of AC distribution junction box, to solve the problem that existing branch means takies the too much space of rack, is difficult to adjust according to the actual requirements the input and output way.
The technical scheme that the utility model provides is as follows:
A kind of AC distribution junction box is made of with the frame that encloses that is connected with the installation panel back side installation panel, is provided with opening on described panel, is provided with the input and output branch apparatus facing to described opening in described bottom surface of enclosing frame.
In above-mentioned AC distribution junction box, described opening upper cover has transparent panel.
Implement the AC distribution junction box that the utility model provides, has following advantage: because junction box is by panel with enclose frame and constitute, volume is little, junction box can be installed in rear of cabinet uses, do not take effective installing space of rack inside, the input and output branch apparatus can adopt terminal and a plurality of air switch to constitute, air switch in the branch apparatus and terminal, can adopt short-circuiting bar to carry out the short circuit combining and configuring according to the actual conditions of rack power supply, realize that a box uses more, do not need to increase other material, can be combined into 2 the tunnel easily and import 4 tunnel outputs, 3 the tunnel import 4 tunnel outputs, 4 the tunnel import multiple inputs such as 4 tunnel outputs, to satisfy different power demands.Simultaneously easy to operate.Satisfied the requirement that rack produces owing to the flexible configuration of internal unit to the different electrical power input.Because it can be installed in the back side of rack, make the very convenient of maintenance and operation change simultaneously.
Below in conjunction with accompanying drawing, further specify the utility model with embodiment.

Embodiment
With reference to Fig. 2, Fig. 3, the AC distribution junction box is made of with the frame that encloses that is connected with the installation panel back side installation panel, is provided with opening on panel, is provided with the input and output branch apparatus facing to opening in the bottom surface of enclosing frame.
Installation panel is provided with four installing holes, is convenient to be fixed on rear of cabinet.For watching the aspect, can in the middle of housing, a transparent emissive plastic glazing be housed, the installation situation of junction box on rack is as shown in Figure 3.
With reference to Fig. 4, the input and output branch apparatus can adopt air switch and binding post to constitute, be provided with four air switches 2,3,12,13 shown in the figure in the branch apparatus, 6,7,8,9 and four ground wire terminals 4,5,10,11 of four zero terminals, the bottom of air switch, zero terminal and ground wire terminal connects live wire, zero line and the ground wire of input power cord respectively, and the top of air switch, zero terminal and ground wire terminal connects live wire, zero line and the ground wire of out-put supply line respectively.The left side two air switches 2,3 and zero terminal 6,7 respectively by short-circuiting bar 15,16 by screw 19,20,21,22 short circuits, two skies in the right open 12,13 and zero terminal 8,9 respectively by short-circuiting bar 18,17 by the screw short circuit.Short-circuiting bar all is installed on the terminal board under the normal condition.
The distribution principle as shown in Figure 5.Two groups of terminals can realize importing for one 1 the tunnel 2 tunnel outputs respectively about junction box at this moment, realize importing for two 1 the tunnel 2 tunnel outputs altogether and promptly 2 the tunnel import 4 tunnel outputs.Sometimes, the equipment of configuration is in order to work more reliably in the rack, have 3 power modules, adopt the 2+1 powering mode, be to be that 2 power modules are worked simultaneously under the normal condition, when wherein any one breaks down, the 3rd power module replaces trouble power to work on immediately, they need rack to provide 3 the tunnel independently to import, as long as the short-circuiting bar about at this moment removing on any one group of air switch and the terminal, make this group air switch and terminal independent fully, just can make this organize 1 the tunnel and import 2 tunnel outputs and become 2 the tunnel and import 2 tunnel outputs, can realize that altogether 3 the tunnel import 4 the tunnel and export.Its distribution principle as shown in Figure 6.In like manner, if short-circuiting bar is all removed, 4 live wire skies are opened with 4 zero terminals just independent fully, and junction box became 4 the tunnel and imported 4 tunnel outputs this moment.
Except that the above-mentioned execution mode that provides, can also provide enough spaces to hold more terminal and air switch by optimization the junction box structure, therefore this junction box can and increase air switch and terminal be realized more input and output way by structure optimization, and two skies are opened such as increasing again, zero line and ground wire terminal can realize that 6 the tunnel import 6 tunnel outputs, 3 tunnel and import the corresponding relations of input and output such as 6 tunnel outputs by the method for aforementioned adjustment short-circuiting bar respectively.
