Abstract
The utility model relates to a pluggable mounting mode between a capacitance plate and a main board in an air conditioning frequency-changer, which realizes the quick connection of an electrical circuitry through a clamping groove, a buckle and a connecting finger, a support of a capacitance is supported and fixed through a C-shaped supporting column, and the capacitance plate can be conveniently replaced through adopting the device,.
Description
The present utility model relates to air conditioning frequency converter, particularly relates to the installation of air conditioning frequency converter internal capacitance plate and the device of replacing, adopts this device can change capacitor board easily.
Background technology
At present, be designed to 8-10 the useful life of air-conditioning, because the physical characteristic of electrochemical capacitor itself and the restriction of design and manufacture cost, the life-span of the electrochemical capacitor of installing on the frequency changer direct current bus has only 2 years usually, makes electrochemical capacitor to regularly replace.But the dc bus electrochemical capacitor of general air conditioning frequency converter directly is welded on the mainboard, makes and changes electrochemical capacitor, just must pull down mainboard earlier, then the electrochemical capacitor that damages on the mainboard is disassembled.The dismounting and change operation of electrochemical capacitor, labor intensive not only, and cause the damage of main circuit board easily, caused unnecessary loss.In order to address this problem, also there is employing that electrochemical capacitor is separated from mainboard, independently become the method for a capacitor board.Usually, this method is fixed on capacitor board on the panel beating substrate by screw, copper post or support column, by patch cord capacitor board is electrically connected with mainboard then.But this method still will be taken off capacitor board by instrument from the panel beating substrate, not convenient at the actual installation scene.
Summary of the invention
In order to overcome the installation and design defective of electrochemical capacitor on the existing air conditioning frequency converter mainboard.The utility model provides a kind of new electrochemical capacitor mount scheme.This scheme can be saved the operation of electrochemical capacitor on the dismounting mainboard, also can omit dismounting electrochemical capacitor plate, can simplify the process of maintenance greatly, saves cost of labor.
The present utility model solves the problems of the technologies described above the technical scheme that is adopted: as Fig. 2, shown in Figure 3, at first the electric capacity on the mainboard is separated, set up separately a capacitor board, then being connected between capacitor board and mainboard, adopt connected mode by plug.The mainboard side is installed a draw-in groove, draw-in groove two ends band buckle with welding.And one side of capacitor board is designed to a socket, and a semicircle breach is opened on the both sides of socket respectively, buckle can by this semicircular breach tightly fasten capacitor board, form a firm link.Simultaneously, the socket of capacitor board is pcb board, the suitable insertion draw-in groove of size design.This is two gold-plated electric contact copper sheets (generally being called golden finger) that expose above socket, between these two golden fingers a breach that is used to locate is arranged.When golden finger inserted draw-in groove, capacitor board and mainboard had formed a complete circuit on electric and have been connected.In addition, as shown in Figure 3, Figure 4, two support columns that are fixed on the substrate are used in the support of capacitor board, and the coupling part of support column and capacitor board is designed to the C font.These two support column left-right symmetric, the coupling part forms chute, and capacitor board is stuck in the chute the inside and can slides.Simultaneously, also to open two disengaging breach on the capacitor board, after capacitor board slides into indentation, there, can partly detach, reach the purpose of taking off capacitor board from the chute of support column.So just can realize the capacitor board plug easily, quick-replaceable function.
Effect of the present utility model is, simplified and installed and the maintenance step, improved operating efficiency, saved cost.
Description of drawings
Below in conjunction with accompanying drawing and implementation process the utility model is further specified.
Fig. 1 is the right view of system.
Fig. 2 is the top view of system.
Fig. 3 is the vertical view of system, the figure before mainboard is connected with capacitor board.
Fig. 4 is a mainboard and figure after capacitor board point is connected.
Among all figure: mainboard (1), draw-in groove (2), buckle (3), projection (4), socket (5), support column (6), panel beating shell (7), capacitor board (8), golden finger (9), location notch (10), semicircle breach (11), electric capacity (12), breach (13)
Embodiment
In Fig. 3, earlier mainboard is fixed on the panel beating shell (7).Buckle (3) on the draw-in groove (2) is outwards broken into two with one's hands.Two support columns (6) on the suitable fixed-site of substrate pass through breach (13) with capacitor board as figure again, and placement is gone down.Then capacitor board is moved to the left and inserts in the draw-in groove, at this moment the footing of buckle causes the rotational automatic semicircle breach (11) that fastens capacitor board of buckle owing to be subjected to pushing of capacitor board socket (5) on the draw-in groove.As shown in Figure 4, the vertical view that assembles exactly.The effect of golden finger (9) is to be electrically connected, and electric current just shuttles back and forth between mainboard and capacitor board by golden finger.The effect of support is not only in the effect of support column, and the design of support column is also played and prevented capacitor board rocking up and down in machine.As capacitor board being taken off, as long as the kick of pinning on the buckle (4) is outwards broken buckle into two with one's hands, capacitor board just ejects from draw-in groove automatically.
Claims (3)
1. the design of power amplifier board in the air conditioning frequency converter is characterized in that power amplifier board realizes being connected and disconnecting by the plug interface with capacitor board.
2. design according to claim 1 is characterized in that on limit of power amplifier board installing a draw-in groove, and one side draw-in groove two ends band buckle is with the socket that is designed to of capacitor board.
3. according to the described design of claim 1, capacitor board supports by support column, and capacitor board can be free to slide on support column, and the place that support column is connected with capacitor board is in order to prevent the capacitor board double swerve, to play the antivibration effect for the design of C font.
