When the electric apparatus is used, the knife switch is closed, and when not used, the knife switch is cut off. The utility model which can ensure the reliable use of high power electric appliance has the characteristics of safety, easiness, quickness, reliable connection, no space usage, etc.

Description

Multi-functional single-phase plug-in strip

The utility model relates to and is used for cutting off and closing the single-phase plug-in strip that closes AC-DC Circuit in a kind of low-voltage circuit, especially sets up the multi-functional single-phase plug-in strip of socket at plug-in strip line outlet place.

At present, the structure of known single-phase plug-in strip is to be formed by combining by base, inlet wire sluice gate, handle, cutter hub, line outlet, Bakelite Cover.During use, load onto suitable fuse, plug-in strip is concatenated in the circuit, firm banking covers Bakelite Cover, comes the cut-out of control circuit and pass to close by handle.But, in practical operation, sometimes for connecing patch, mounting receptacle or directly open the plug-in strip Bakelite Cover in power distribution cabinet normally, the place directly goes between at line outlet, is very much trouble, and is dangerous.In addition, when using the bigger household electrical appliance of air-conditioning constant power, for safety, plug when generally using, the time spent does not pull up, because this type of appliance starting electric current is bigger, when plug, electrical equipment is damaged, need before socket, to install single-phase plug-in strip usually and control, general single-phase plug-in strip does not have the function of socket, brings unnecessary trouble to the user.

The utility model provides a kind of multi-functional single-phase plug-in strip, it can not only fast shut-off and closes the zygonema road, and owing to set up socket at the line outlet place, make the temporary line attachment security, easy, rapid, refute and connect reliably, do not take up room, guarantee the reliable use of high-power household electrical appliance such as air-conditioning simultaneously.

The purpose of this utility model is achieved in that on base, when connecting fuse, when closing plug-in strip, the inlet wire sluice gate, cutter hub, fuse, line outlet is electrically connected, arrangements of electric connection to single-phase plug-in strip line outlet improves simultaneously, set up a socket, this socket elastic copper sheet is fixed on the boss of setting up at base line outlet place with following pile crown by screw, elastic copper sheet one end contacts with base, the other end is connected with following pile crown, following pile crown on the upper side portion set up a fixing hole, screw by base boss bottom elastic copper sheet, following pile crown connects firm, following pile crown one termination fuse, another termination lead-out wire, following both distances of pile crown are little than both distances of incoming line pile crown, and are placed in the groove, offer socket aperture on Bakelite Cover, for the plug-in strip of setting up two pole sockets, following pile crown is answered parallel placement, and distance is as the criterion with the two poles of the earth plug distance, and two jacks are set on the Bakelite Cover simultaneously; For three pole sockets, should set up an Earth pile-head, twice pile crowns should oblique placement, and three jacks are set on the Bakelite Cover simultaneously, during use the two poles of the earth plug or three-terminal polarized plus plug is inserted in the corresponding socket to get final product.

Owing to adopt such scheme, can make the function that plug-in strip possesses socket, when connecing temporary line safety, easy, rapid, refute and connect reliably, do not take up room; Guarantee the reliable use of high-power household electrical appliance such as air-conditioning simultaneously, only set up a socket at the plug-in strip line outlet, simple in structure.

The utility model further specifies during below in conjunction with drawings and Examples:

Fig. 1 is first embodiment vertical view of multi-functional plug-in strip;

Fig. 2 is second embodiment vertical view of multi-functional plug-in strip;

Fig. 3 is the A-A cutaway view of Fig. 1.

Among the figure: 1, base; 2, handle; 3, cutter hub; 4, inlet wire sluice gate; 5, line outlet; 6, base boss; 7, socket elastic copper sheet; 8, line outlet pile crown; 9, fixed screw; 10, lead-out wire, 11, the earth connection pile crown, 12, fuse.

In enforcement shown in Figure 1, locate to be provided with two pole sockets at plug-in strip line outlet (5), socket elastic copper sheet (7) one ends contact with base boss (6), the other end contacts with line outlet pile crown (8), and be fixed on the base boss (6) by fixed screw (9), two line outlet pile crowns (8) are answered parallel design, distance is smaller than two inlet wire sluice gates (4) distance, and it is corresponding with two jacks on the Bakelite Cover, line outlet pile crown (8) vertical section is L shaped, internal thread is arranged in the interstitial hole, one end stretches in the socket copper sheet (7), and the top screw is used for connecing fuse (12), and the bottom connects lead-out wire (10).

In embodiment illustrated in fig. 2, locate to be provided with three pole sockets at plug-in strip line outlet (5), by fixed screw (9) socket elastic copper sheet (7) and line outlet pile crown (8) are fixed on the base boss (6), two line outlet pile crowns (8) are answered oblique placement, Earth pile-head (11) is fixed on the base (1), earth connection should pass base and be fixed on the earth connection pile crown (11), and jack should be corresponding with it on the Bakelite Cover.
