Embodiment

Now in conjunction with the accompanying drawings execution mode of the present utility model is further described:

As shown in the figure, the embodiment of a kind of breaker of plastic casing connector of the utility model embodiment, include housing 1, it is corresponding with three-phase bus 6 respectively that three groups of hooks 8 are housed in the bottom surface of housing 1, also be respectively equipped with three gusset pieces 5 longitudinally in the bottom side of housing 1, these three gusset piece 5 one ends are separately fixed at and are used for the screw 9 that is connected with breaker of plastic casing, the other end of these three gusset pieces 5 is respectively corresponding with corresponding hook 8, on housing, also be provided with the slide plate 3 of three horizontally sets, these three groups of slide plates 3 respectively with three gusset piece 5 square crossings, front end at every slide plate 3 is provided with inclined-plane 31, between this inclined-plane 31 and gusset piece, establish wedge 4, wedge 4 constitutes wedge with the inclined-plane of slide plate 3 and cooperates, and also is provided with the mechanism 2 that drives slide plate 3 horizontal slippages on housing 1.During use, hang over bus 6 on by hook 8 connector after, drive slide plates 3 by mechanism 2 again and move to right, utilize the inclined-plane 31 of slide plate 3 front ends to drive wedges 4 to bottom offset, be adjacent to bus 6 thereby drive gusset piece 5, realize the reliable electrical connection of the two.

This mechanism of mechanism that drives the horizontal slippage of slide plate can be any mechanisms such as pinion and rack, crank mechanism, but consider from the convenience of simple structure and operation, present embodiment adopts eccentric stiffener, this eccentric stiffener 2 includes a upper end and is provided with the biasing post 22 that revolves the rotating shaft 21 of opening hole 23 and be arranged on the rotating shaft lower end, rotating shaft 21 is rotatable to be set in the axis hole 12 of housing 1, be provided with on housing 1 with revolving and open the corresponding inner hexagon spanner inlet 13 in hole 23, biasing post 22 is set in the hole of slide plate 3 front ends.During use, during by inner hexagon spanner rotating shaft 21, the biasing post 22 of rotating shaft 21 lower ends promptly can drive slide plate 3 lateral displacements, thereby can drive wedge 4 to bottom offset by the inclined-plane 31 of slide plate 3 front ends, so just can promote gusset piece 5 is adjacent to bus 6, equally when connector being pulled down from bus, also only use inner hexagon spanner is inserted to revolving of rotating shaft opens to twist in the hole and get final product, operation is very easy and reliably.

In the present embodiment, the side that described each rotating shaft 21 and boss 11 are located at housing 1 place that keeps to the side, each boss 11 of housing 1 is above the primary flat of housing 1 (i.e. the face of fitting with breaker of plastic casing), first slide plate 3 wherein (being uppermost slide plate among the figure) passes first, second gusset piece 5 is (corresponding to the left side among the figure, in gusset piece) the below and act on mutually with the 3rd gusset piece 5 (corresponding to the nethermost gusset piece among Fig. 1), second slide plate 3 (corresponding to the slide plate in the centre position among Fig. 1) passes the below of first gusset piece 5 and acts on mutually with second gusset piece 5, first slide plate 3 and first, be provided with between second gusset piece 5 between insulation board 7, the second slide plates 3 and first gusset piece 5 and also be provided with insulation board 7.Boss 11 is located at the avris of housing 1, just can earlier breaker of plastic casing be installed on the connector when mounted, the installation of breaker of plastic casing can not cover in inner hexagon spanner inlet 13, therefore can again connector be installed on the bus easily, also can directly connector be pulled down when dismantling equally and needn't pull down circuit breaker earlier.Obviously, the structural design that boss is such greatly facilitates user's use.

In the illustrated embodiment, the bottom surface of described wedge 4 is provided with boss 41, also is provided with boss 81 on the corresponding face of the end of described hook 8 and bus 6.Be provided with boss the 41, the 81st,, fit with bus 6 thereby promote gusset piece 5 better in order to reduce the contact area of wedge 4 and gusset piece 5, hook 8 and bus 6.And if do not establish this boss, then can be than higher to the processing request of the end plane of the bottom surface of wedge and hook.

Obviously; though in conjunction with the accompanying drawings the utility model embodiment has been done detailed description; it only is preferred implementation of the present utility model that but those skilled in the art should be understood that above embodiment; and be not qualification to protection range of the present utility model, any improvement of being done based on invention spirit of the present utility model is all naturally in the utility model protection range.
