2, the rational arrangement position of mounting panel, convenient installation is fixed, and effectively make use of installing space.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 of the present utility modelly faces structural representation.
Fig. 2 is side-looking structural representation of the present utility model.
Fig. 3 be in Fig. 2 A to structural representation.
In figure: 1-upper shell; 2-lower house; 3-main terminal; 4-side joint terminal; 5-over cap; 6-wire casing; 7-mounting panel.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, 2, the utility model comprises upper shell 1 and lower house 2, and described upper shell 1 and lower house 2 are detachably installed together, and surrounds the instrument transformer housing that middle part is porose.At least one side surface of described housing is provided with side joint terminal 4, the front surface of described housing and rear surface are respectively equipped with main terminal 3, if the installing space of current transformer is rather spacious, namely when installation environment is fairly simple, main terminal 3 can be selected to carry out wiring, handled easily.
As shown in Figure 3, the side surface of described housing is provided with groove, and described side joint terminal 4 is located in described groove, in prioritization scheme, a described side surface has two grooves, all has two side joint terminals 4 in each groove.Described groove upper end is provided with over cap 5, and recess sidewall is provided with the via hole corresponding with side joint terminal 4, and during wiring, line stretches into groove from via hole and is connected with side joint terminal 4.In prioritization scheme; described over cap 5 one end and side, groove upper end hinged; on the hinge of hinged place, cover has a torsionspring; one fin of described torsionspring and groove inner wall are fixed; another fin and the over cap 5 of torsionspring are fixed; described over cap 5 edge there is projection, groove has the draw-in groove matched with projection.During use, projection is sticked in draw-in groove and namely by over cap 5, side joint terminal 4 is covered.
When the installing space of current transformer is narrower and small; line is connected on side joint terminal 4, due to side joint terminal 4 on the same lateral surface, so install very convenient; the cooperation of over cap 5 and groove avoids the generation of wiring place leaky, improves fail safe to a certain extent.
