Abstract

The utility model relates to a universal socket for single-phase two-pole or three-pole plug, comprising a socket base and a socket cover. Jacks which are suitable for inserting the single-phase two-pole or three-pole plug is arranged on the socket cover. Two connector rotating devices are arranged on the socket base to realize the needed angle and space for inserting the single-phase two-pole or three-pole plug, and consequently, the universal purpose is obtained. The utility model has convenience and practicality, and great convenience can be brought to the use of the user.

Description

Universal socket for single-phase two-or three-pole plug

The utility model relates to a kind of supply socket, is adapted to blanket socket single-phase two, three-terminal polarized plus plug especially.

During existing single-phase two, three utmost point appliances power source plugs use the grafting of the fixed socket of simply connected, must socket, the plug number of poles is corresponding could use.When the fixed socket number of poles of the simply connected of attaching plug and installation not at once, have only and join the fixed or multi-joint mobile jack of double-purpose of corresponding number of poles simply connected in addition, increase expense and time that the user addresses this problem, make troubles to the user.

The purpose of this utility model provides a kind of blanket socket of convenient and practical single-phase two, three-terminal polarized plus plug, to solve the difficult problem that user's plug number of poles is unworthy of joining in addition socket.

The utility model is to improve on the basis of existing single-phase three pole sockets, and it mainly is made up of socket cover and socket base, have on the socket cover can adapt to two, the jack of three-terminal polarized plus plug insertion, two connector whirligigs are arranged on the socket base.

The connector whirligig is made up of connector, bolt, packing ring, pressure spring, nut and lead plate.Connector is rotatable, with adapt to two, three-terminal polarized plus plug inserts required angle and spacing.

The utility model blanket socket is compared with existing socket, has following advantage:

1, can reduce the user because of need buy the expense of respective socket with single-phase two utmost points, three-terminal polarized plus plug, use to the user and bring great convenience.

2, the panel that can improve concealed installation duplex multipurpose socket closes humorous attractive in appearance.

3, can save whole electric conductor parts of a cover two pole sockets to the manufacturing of concealed installation duplex multipurpose socket, reduce manufacturing cost.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a socket base schematic diagram of the present utility model.

Fig. 2 is a socket base A-A section diagrammatic sketch of the present utility model.

Fig. 3 is a socket cover schematic diagram of the present utility model.

The utility model is realized by following measure:

Single-phase two, three utmost point blanket sockets are improved on the basis of existing single-phase three pole sockets, and it mainly is made up of socket base (7) and socket cover (8).Socket cover (8) has and can adapt to jack (9) single-phase two, that three-terminal polarized plus plug inserts, and two connector whirligigs are arranged on the socket base (7).The connector whirligig is made up of connector (1), bolt (2), packing ring (3), pressure spring (4), nut (5) and lead plate (6).The connector whirligig is fixed on the socket base (7), and connector (1) is rotatable, and pressure spring (4) is adjusted the spin friction resistance of connector (1) and lead plate (6), makes it the rotation torque that produces less than connector (1).Realize that by the connector whirligig single-phase two, three-terminal polarized plus plug inserts required angle and spacing, the plug latch inserts connector (1) by jack (9), in the position not at once, latch enters the garden cambered surface by the connector lip, because the not corresponding angle of connector (1), make connector (1) produce rotation torque automatically, connector (1) rotates to corresponding with the latch angle position along bolt (2) center, thereby realizes general purpose.

Claims

1, a kind of single-phase two, three-terminal polarized plus plug blanket socket, it mainly is made up of socket base and socket cover, it is characterized in that: have on socket cover and can fit jack single-phase two, that three-terminal polarized plus plug inserts, socket base has two connector whirligigs, and the connector whirligig is fixed on the socket base.

2, blanket socket according to claim 1 is characterized in that above-mentioned said connector whirligig is made up of connector (1), bolt (2), packing ring (3), pressure spring (4), nut (5) and lead plate (6).
