Abstract

The invention discloses the function of a multi-hole dual-duty low-voltage power supply receptacle and a schematic diagram thereof. The multi-hole dual-duty low-voltage power supply receptacle makes use of one jack of a three-pole plug and a jack parallel with the jack of the three-pole plug as a jack group of a two-pole plug to form a universal receptacle. Just one jack is added to solve the problem that the jacks of a three-pole receptacle can not be used for the two-pole plug. The invention has the advantages that the multi-hole dual-duty low-voltage power supply receptacle is designed by taking full advantage of the surface of the facade of the receptacle so that the multi-hole dual-duty low-voltage power supply receptacle is beautiful and practical; the volume of the receptacle is reduced; the cost is saved; and the multi-hole dual-duty low-voltage power supply receptacle is convenient to users.

Description

Porous dual purpose low-voltage power supply socket

Technical field

The invention relates to a kind of low voltage voltage socket.

Background technology

Existing low-voltage power supply socket has two spring hole scokets that are applicable to the two poles of the earth plug, and the Three-hole socket that is applicable to three-terminal polarized plus plug is arranged, and also has existing three jacks that the modular jack of two jacks is arranged again.But the jack on the various socket generally can not be shared, just can not give the two poles of the earth plug shared as three utmost point jacks, because three utmost point insertion hole groups are isosceles triangles, and the two poles of the earth insertion hole groups is parallel.So isosceles triangle three pole sockets use also just can not for the two poles of the earth plug, bring inconvenience to life and work, also are unfavorable for the appropriate design of modular jack.

Summary of the invention

The objective of the invention is can not give the shared shortcoming of the two poles of the earth attaching plug in order to solve the isosceles triangle three pole socket jacks in the above-mentioned supply socket, and the porous dual purpose low-voltage power supply socket of design.

For achieving the above object, the technical scheme that the present invention takes is: a kind of isosceles triangle Three-hole socket that can use to three-electrode power plug, its isosceles triangle jack top is the ground wire of power supply, the lower end jack is the live wire or the zero line of power supply, then on this basis, design a parallel with it supply hub again on one side of the lower end of isosceles triangle jack live wire or zero line jack, then the power line of its power line and pairing three utmost point jacks is coupled together, if three utmost point jacks are live wires then newly-increased jack is exactly a zero line; Otherwise if three utmost point jacks are zero lines, the newly-increased jack line of just starting to exchange fire forms one group of parallel jack that can be used for the two poles of the earth plug.On three utmost point receptacle electrical connectors, only need to increase a jack like this and just can become the blanket socket that is applicable to three-terminal polarized plus plug and the two poles of the earth plug simultaneously, i.e. porous dual purpose low-voltage power supply socket with live wire or ground line parallel.

For the purpose of more both artistic and practical, another embodiment of the present invention is: this receptacle sockets is designed to the dual-purpose herringbone jack in five holes, promptly utilize the jack of the right and left in the lower end of isosceles triangle jack, increase a parallel with it jack separately again, promptly the live wire of three utmost point jacks is connected with the zero line of newly-increased parallel jack, and of the live wire connection of the zero line of three utmost point jacks with newly-increased parallel jack, form two groups of the two poles of the earth supply hubs, not only can use but also can be for two the two poles of the earth plugs for a three-terminal polarized plus plug use.The herringbone five hole dual purpose low-voltage power supply sockets that this socket become have five jacks.

The present invention also has a kind of embodiment to be: above-mentioned porous dual purpose socket or the dual-purpose socket in herringbone five holes and safeties, switching device and timer are coupled together becomes the novel combination type low-voltage power supply socket.

Concrete enforcement

Below in conjunction with accompanying drawing embodiment its operation principle is described.

Fig. 1 is a porous dual purpose low-voltage power supply socket.

Fig. 2 is five hole dual purpose low-voltage power supply sockets.

Fig. 3 is the novel combination type low-voltage power supply socket.

Embodiment one:

As shown in Figure 1: (1) is the firewire jack of three utmost point jacks, ground wire jack, (3) that (2) are three utmost point jacks For socket, (4) are that zero line jack, (5) of three utmost point jacks are the firewire jack of the two poles of the earth plug-socket. As Fruit jack (4) is live wire, and then jack (5) is zero line; Jack (4) and the parallel formation one of jack (5) Group the two poles of the earth insertion hole groups, jack (1), (2), (4) then are three utmost point insertion hole groups, and jack (5) also can Be located at the left side and a pair of the two poles of the earth of the parallel formation of jack (1) insertion hole groups.

Embodiment two:

Be illustrated in figure 2 as five hole dual purpose low-voltage power supply sockets, present embodiment and embodiment one are basic identical, the difference part jack (6) that has been many, and jack (6) is parallel with jack (1), and forms the two poles of the earth insertion hole groups and use for the two poles of the earth plug.

Embodiment three:

Be illustrated in figure 3 as multifunctional low-voltage supply socket box: (1) is that Timing power supply jack, (6) be switch for normal open supply hub, (4) for timer, (5) for safeties, (3) for external general supply line, (2).Timer (4) can be controlled the dual-purpose insertion hole groups of socket the latter half, and the dual-purpose insertion hole groups of socket the first half then is the double-purpose electric source jack of normal open electricity.

The present invention has scientifically utilized a jack in three utmost point jacks as the parallel jack of the two poles of the earth plug, so only need increase a jack, just can make three pole sockets become general socket.So just the surface area that can make full use of the socket front designs, and makes it both beautiful and practical, can also dwindle the volume of socket, saves cost, makes things convenient for the user.

Claims (3)

1, a kind of low-voltage power supply socket with the isosceles triangle jack that can use for three-terminal polarized plus plug, the top jack is a ground wire jack, two jacks in lower end are respectively live wire or zero line jack, it is characterized in that: also have a supply hub parallel with live wire or zero line in three utmost point jacks at least in the lower end of this isosceles triangle jack, its power line and zero line or live wire connect to form one can be for the supply hub group of the two poles of the earth plug use.

2, porous dual purpose low-voltage power supply socket according to claim 1 is characterized in that: the firewire jack and the zero line jack of the lower end of isosceles triangle three utmost point jacks, respectively having a parallel with it jack to partner respectively can be for the insertion hole groups of the two poles of the earth attaching plug use.
