Abstract
The utility model relates to a plastic single-phase universal three-pole flat socket, belonging to the daily low-voltage (250V) power socket. The utility model is provided with a grounding wire sleeve, a fire wire sleeve and a neutral wire sleeve. The fire wire sleeve and the neutral wire sleeve of the socket can be arranged at correspondingly positions which are mutually parallel or positions which form an angle of 60 DEG through a two-pole or a three-pole flat plug under the pushing force of a contact sleeve cover (6). The plastic single-phase universal three-pole flat socket of the utility model has simple structure, and the size of the utility model is similar to the size of the existing three-pole flat socket. The utility model has the function that the two-pole or three-pole flat plug can be directly plugged.
Description
The utility model belongs to daily low pressure (250V) supply socket.
The existing low single-phase flat socket of compression molding material has two kinds, and a kind of is three pole sockets of band earth connection, and this socket live wire and the neutral line two jack positions are mutually 60 °; Another kind is two pole sockets of not being with earth connection, and this socket live wire is mutually parallel with the neutral line two jack positions.The use that all can not be mixed of these two kinds of plugs, socket.
Be connection illuminating lamp, hair dryer, electric comb in the daily life ... to adorn two pole sockets etc. overall plastic electrical equipment: for connecting washing machine, pedestal fan, refrigerator ... adorn three pole sockets again in metal shell electrical equipment.If lack a kind of socket in same place, make troubles for the use of above-listed electrical equipment, sometimes existing one two utmost point has one three pole socket again in same place, in the time of connecting the power supply of two (only) two utmost points or three pole sockets simultaneously, equally also can produce difficulty.At this moment people have only the two kinds of methods that adopt: (one) adjunction one cover plug, socket mapping device, but when two pole sockets are transformed into three pole sockets is because ground path not in fact is unsafe.(2) transform plug.Can insert Xiao to two of two-wire plug and pull that to be twisted into be 60 ° of positions, inject the live wire and the neutral line jack energized of three pole sockets, but three-terminal polarized plus plug can not be transformed and injects two pole socket energized.Use above-listed (one), (two) two methods not only to increase expense, cause many troubles, and potential danger factor.
The purpose of this utility model provides a kind of plastics single-phase universal three utmost point flat sockets, and it can patch single-phase three utmost point flat plugs, can patch single-phase two utmost point flat plugs again.
The purpose of this utility model is achieved in that in single-phase three utmost point flat sockets, sleeve of its live wire and the neutral line etc. is installed in the vinyl cover and the coaxial aperture between the base plate of socket, and can rotates 30 ° along the axle center.When patching two utmost points or three-terminal polarized plus plug,, insert Xiao by the neutral line and live wire and promote the inclined-plane that sleeve covers, make it be rotated into the relevant position, thereby reach the purpose of energized if live wire and the neutral line two jacks and slotting Xiao position are not simultaneously.
Owing to adopt such scheme, only increase the rotating mechanism of live wire and the neutral line two sleeves, just can make single-phase three utmost point flat sockets become the blanket socket that two utmost points or three extremely all can patch, simple in structure, easy to use.
Below in conjunction with embodiment, the utility model is described in further detail.
Fig. 1 is the utility model embodiment winding diagram.
Fig. 2 is Fig. 1 I-I position cutaway view.
Fig. 3 is that the socket of live wire sleeve lid and neutral line sleeve lid is located parallel position mutually, when patching three utmost point flat plugs, and sleeve lid position of rotation schematic diagram.
Fig. 4 is that the socket of live wire sleeve lid and neutral line sleeve lid is in 60 °, when patching two-wire plug, and sleeve lid position of rotation schematic diagram.
Among the figure 1, plastic bottom board 2, earth connection sleeve 3, earth connection socket 4, hold-down screw 5, vinyl cover 6, neutral line plastics sleeve lid 7, live wire plastics sleeve lid 8, the neutral line, live wire sleeve 9, screw 10, terminal block 11, soft line 12, copper sleeve 13, terminal block 14, screw 15, three heart yearns 16, terminal block 17, hold-down screw 18, plug live wire insert Xiao 19, the plug neutral line is inserted Xiao.
Present embodiment is mainly by the earth connection sleeve in Fig. 1, live wire sleeve and neutral line sleeve are formed, carry the earth connection of three heart yearns (15) of power supply directly receive earth connection sleeve (2), the right side neutral line and left side live wire respectively by terminal block (13), soft line (11), draw and be connected on the neutral line, the live wire sleeve (8).The V-arrangement open slot of the neutral line, live wire sleeve (8) can be formed 60 ° (positions among the figure) mutually or rotate 30 ° of one-tenth parallel positions.The square inner bore of neutral line plastics sleeve lid (6) and live wire plastics sleeve lid (7) matches with the neutral line, live wire sleeve (8) (simultaneously referring to Fig. 2), and the rectangle socket is consistent with two sleeve V-arrangement open slot directions.
The visible neutral line in Fig. 2, live wire sleeve (8) is installed in the coaxial aperture of socket plastic bottom board (1) and vinyl cover (5) by the ailhead of screw (17) and the convex shoulder of cover neutral line sleeve lid (6) thereon respectively, and the rectangle socket is consistent with sleeve V-arrangement open slot direction.
By Fig. 3, Fig. 4 as seen, the rectangle loudspeaker socket limit of neutral line plastics sleeve lid (6) and live wire plastics sleeve lid (7), be divided into by minor axis center line MM and become four deltas of a, b, c, d of 30 ° with the socket limit, these deltas all become 40 ° of inclined slopes (simultaneously referring to Fig. 2) to the socket direction.When the socket of neutral line plastics sleeve lid (6) and live wire plastics sleeve lid (7) when scheming (3), two-wire plug can directly patch; When patching three-terminal polarized plus plug, 60 ° two slotting Xiao (18), (19) contact the live wire plastics respectively and insert lid (7) b, d two triangle slope and neutral line plastics sleeve lid (6) a, c two triangle slope each other, because thrust, sleeve lid (6), (7) of plug when patching rotate 30 ° along the direction of arrow respectively, slotting Xiao of three-terminal polarized plus plug this moment gets final product socket.When neutral line plastics sleeve lid (6) and live wire sleeve covered the socket of (7) such as Fig. 4, three-terminal polarized plus plug can directly patch; When patching two-wire plug, parallel each other two slotting Xiao (18), (19) contact live wire plastics sleeve lid (7) a, c two triangle slope and neutral line plastics sleeve lid (6) b, d two triangle slope respectively, because the thrust of plug when patching, along 30 ° of direction of arrow rotations, two-wire plug is inserted Xiao and is got final product socket respectively for sleeve lid (6), (7).
