Description

The end box of connection capable of being combined

Technical field

The utility model relates to the end box of a kind of switch or socket, especially a kind of end box of connection capable of being combined.

Background technology

Switch, socket are the electric components of widely using, and have the effect of control, UNICOM's electric equipment break-make.For relatively-stationary switch of operating position or socket, usually take the mode of concealed installation to install, that is, the predetermined position that switch or socket are installed has the chamber groove in advance in wall, imbed end box in the groove of chamber, functional part and the panel with switch or socket is installed on the end box again.End box is made up of box body and the fixture that is used for fixing the functional part of switch or socket usually, and knock down hole is left in its sidewall and bottom surface.Be installed during box the end, with the knock down hole abate of required connection raceway for wiring, link to each other with pre-buried raceway for wiring, electric wire passes raceway for wiring, leaves power lug in end box.When switch or socket are installed, power lug is connected on the binding post in switch or the function of socket parts, and is fixed on the fixture of end box, outside the functional part of switch or socket, install panel at last again additional with the installing hole that screw passes functional part.

When needing a plurality of switches or socket to install side by side, especially cooperate when installing, often box of a plurality of ends fitly need be embedded into body of wall, and make uniform spacing of maintenance between each end box with multidigit Contiuum type panel.If the spacing between each end box is inconsistent, when installation panel, may be owing to can't matching with positions of panels and can't being installed exactly.Mainly address the above problem by two kinds of methods at present: a kind of method provides the special-purpose end box supporting with the Contiuum type panel, and box is difficult to other panel general usually at the bottom of this kind; Another kind method is on the general end box syndeton to be set, and it can be fitted together, and marshalling, has uniform spacing.

CN2645308Y, CN2697880Y and CN2416647Y disclose some end boxes that can be connected, the structure of these end boxes contains more boss and groove, processing and mounting hardness have been increased, in addition, each end box directly links together, its combination back is together adjacent, is not easy to connect electric wire and the Contiuum type panel is installed.

CN2840423Y discloses case connecting structure of a kind of end, and end box can be linked to each other by connector.Fig. 1 is the stereogram with box of the single end of this syndeton 1, the sidewall of box body 10 is provided with joint tongue 11, with sidewall that this sidewall parallels on correspondingly be provided with the tongue-and-groove 12 (referring to Fig. 3) that can match with joint tongue 11, also be provided with projection 13 (referring to Fig. 3) and 14 on the sidewall.Be provided with connector 2 between the end box 1, shown in Fig. 2 A and Fig. 2 B, connector 2 has and the joint tongue 11 of end box 1 and tongue-and-groove 12 matches be connected tongue-and-groove 22 and be connected joint tongue 21, and the guide

vane end stop

23 and 24 that matches with the projection 13 and 14 of end box 1.Box 1 schematic diagram of state that is connected at the bottom of Fig. 3 is two, box 1 is connected together by connector 2 at the bottom of two.Though this syndeton can link together box of a plurality of ends, and marshalling, from Fig. 1-3 as can be seen, the syndeton of this end box and connector is still comparatively complicated, and difficulty of processing is bigger, can increase production cost.In addition, when being connected or dismantle, need the accurate position of aiming at end box and connector, be not easy to install, and easily fracture because of undue force causes the joint tongue tongue-and-groove.
