Abstract
The utility model discloses a sealing cover for a variable-capacitance joint, belonging to the field of variable-capacitance joint connecting devices. The sealing cover comprises a bottom plate and a vertical plate that are vertical to each other and are connected with each other into a whole; two side plates are arranged vertically on the bottom plate and are arranged in parallel with each other; a plurality of copper bars are arranged between the two side plates; and insulative clamping blocks are used for isolating the copper bars and isolating the copper bars and the side plates. When the device is matched with a connector to connect a large-current bus and a small-current bus, the small-current bus is arranged at one side of the connector, the large-current bus is arranged at the other side of the connector, and the copper bar on the variable-capacitance joint cover and the small-current bus are inserted in one side of the connector in parallel, so that the copper bar of the connector can be well supported at the small-current bus side and the large-current bus side; and after screws of the connector are tightly locked, the copper bars at two sides of the connector are subject to load uniformly and have good contact, so that the reliability of electric connection is ensured. The device is specially used for connecting the large-current bus with the small-current bus.
Description
Technical field
The utility model relates to a kind of electrical connection arrangement, particularly a kind of transfiguration joint jockey.
Background technology
In the prior art, need sometimes heavy current busbar and little current bus bar are interconnected, because heavy current busbar is a two-row structure, and little current bus bar is a single row configuration, and the cross section difference of bus and the difference of busbar bring difficulty for both butt joints; When assembling, respectively the socket of bus phase line is gone in the connector, again bolt is tightened up, Yi Bian if busbar is arranged, Yi Bian there is not busbar, must cause the connector unbalance stress, connector tightens up to the one side that lacks busbar, one side and opening of busbar arranged, the contact area of busbar and connector reduces, current capacity after causing connecting reduces, and influences dependability.
The utility model content
The purpose of this utility model provides a kind of transfiguration joint sealing cover, and it can successfully reliably be connected heavy current busbar with little current bus bar by matching connector.
The purpose of this utility model is achieved in that a kind of transfiguration joint sealing cover, comprise base plate and riser vertical mutually and that be connected as a single entity, upright and be arranged in parallel and be provided with two blocks of side plates on the base plate, be provided with some copper bars between the biside plate, reach between copper bar and the side plate isolated between the described copper bar through the insulation fixture block.
When this device is connected heavy current busbar with the connector cooperation with little current bus bar, little current bus bar is arranged on connector one side, heavy current busbar is arranged on the connector opposite side, copper bar and little current bus bar on the transfiguration joint cover insert connector one side side by side, make the copper bar of connector all can obtain good supporting at the opposite side of little current bus bar one side and heavy current busbar, after the screw lock of connector, the copper bar stress equalization of connector both sides, contact is good, has guaranteed the reliability that is electrically connected.This device is exclusively used in heavy current busbar is connected with little current bus bar.
Utilize side plate and insulation fixture block fixed copper row for further facilitating, the described biside plate outside is respectively equipped with fixed angles aluminium, is connected through screw between described fixed angles aluminium and the base plate, fixedlys connected with side plate through the bolt fixture block that will insulate between the fixed angles aluminium of both sides.
For providing better protection to device, described base plate and riser both sides are provided with bending edges.Bending edges itself has certain intensity, can be shock-resistant, and simultaneously, bending edges also plays booster action, has strengthened the intensity of base plate and riser.
For improving the class of insulation, described riser is provided with the sponge lining towards a side of copper bar.The sponge lining has insulating effect, can make that the class of insulation improves between copper bar and the riser.
For ease of installing and fixing, described base plate is provided with the connection pawl away from an end of riser.
Description of drawings
Fig. 1 is this practical three-dimensional structure diagram.
Fig. 2 is the annexation explosive view of transfiguration joint.
Wherein, 1 riser, 2 copper bars, 3 insulation fixture blocks, 4 side plates, 5 base plates, 6 connect pawl, 7,9 bending edges, 8 fixed angles aluminium, 10 sponge linings, 11 transfigurations joint sealing cover, 12 little current bus bars, 13 connectors, 14 heavy current busbares.
Embodiment
As shown in Figure 1, be transfiguration joint sealing cover, it comprises orthogonal base plate 5 and riser 1, base plate 5 and riser 1 both sides are provided with bending edges 7,9, upright and be arranged in parallel and be provided with two blocks of side plates 4 on the base plate 5, be provided with some copper bars 2 between the biside plate 4, reach between copper bar 2 and the side plate 4 isolated between the copper bar 2 through insulation fixture block 3; Biside plate 4 outsides are respectively equipped with fixed angles aluminium 8, are connected through screw between fixed angles aluminium 8 and the base plate 5, fixedly connected with side plate 4 through the bolt fixture block 3 that will insulate between the two fixed angles aluminium 8; Riser is provided with sponge lining 10 towards a side of copper bar 2, and base plate 5 also is provided with connection pawl 6 away from an end of riser 1; Above-mentioned base plate 5, riser 1, bending edges 7,9 and be connected pawl 6 and be connected as a single entity adopt impact style to make.
When this device uses, as shown in Figure 2, little current bus bar 12 and transfiguration joint sealing cover 11 are arranged on connector 13 1 sides, heavy current busbar 14 is arranged on connector 13 opposite sides, copper bar 2 on the transfiguration joint cover inserts connector 13 1 sides side by side with little current bus bar 12, this connector 13 can adopt that the patent No. is in the prior art: the bus tie of ZL200820035951.2, the copper bar of this connector 13 all can obtain good supporting at the opposite side of little current bus bar 12 1 sides and heavy current busbar 14, after the screw lock of connector 13, the copper bar stress equalization of connector 13 both sides, contact is good, has guaranteed the reliability that is electrically connected.
