Abstract

The utility model discloses single phase AC power plug and socket belongs to electrical apparatus, especially involves a single phase AC power plug and socket, and this plug and socket designs a T shape structure, and plug and socket inserts for the orientation, makes the difficult wrong insertion of phase line and zero line two poles of the earth, and after the plug inserted the socket, the contact surface increase, plug cross atress, the contact is good, is difficult for droing between plug and the socket, and single phase AC power plug and socket is applicable to all kinds of electrical apparatus.

Description

Socket for single phase power supply

Utility model single phase alternating current power supply plugs and sockets belongs to appliance device, relates in particular to a kind of single phase alternating current power supply plugs and sockets.

Existing single phase alternating current power supply plugs and sockets generally adopts run-in index flat plugs and sockets, though have certain effect in actual use, but also exist some defective, mainly be that phase line and zero line the two poles of the earth are difficult to distinguish, easy misplug, even cause the not charged originally electricity of but being with of some apparatus casing, plugs and sockets self cooperate unreasonable, often come in contact badly, phenomenon such as come off easily.

The utility model single phase alternating current power supply plugs and sockets provides a kind of single phase alternating current power supply T shape plug and T shape socket, makes plugs and sockets reach self and cooperates rationally, is difficult for misplug, and difficult drop-off contacts good purpose.

In order to realize above-mentioned purpose, its technical scheme is as follows: the single phase alternating current power supply plugs and sockets changes T shape structure into by the run-in index flat, one of two inserted sheet of T shape plug are vertical inserted sheets, another is parallel inserted sheet, T-shaped state, and on two inserted sheets, a convex key is set respectively, the jack of T shape socket, reed also is a T shape structure corresponding to the inserted sheet of T shape plug, on two reeds a gib key is set respectively, when T shape plug inserts T shape socket, a vertical utmost point that inserts is a phase line, and a utmost point of parallel insertion is a zero line, like this, T shape plug inserts T shape socket and is referred to as directed the insertion, simultaneously, the inserted sheet of T shape plug injects in the T shape Die for Reeds of Connector Jack, and the gib key of the convex key of inserted sheet and reed matches, and both contact-making surfaces are increased, at this moment after T shape plug inserts T shape socket, make T shape plug cross stressed, like this, difficult drop-off between T shape plug and the T shape socket, and contact is reliable.

It is as follows that the utility model single phase alternating current power supply plugs and sockets and existing single phase alternating current power supply plugs and sockets are compared the characteristics that have: the one, and plug insertion socket is directed the insertion; The 2nd, behind the plug insertion socket, the plug cross is stressed; The 3rd, difficult drop-off between plug and the socket, the reliability of contact greatly strengthens.

Below in conjunction with the embodiment accompanying drawing this application technology being done one describes in detail.

Fig. 4 single phase alternating current power supply plug contacts stress figure with socket

Fig. 1 single phase alternating current power supply plug is a T shape structure, two inserted sheets of T shape plug, and one is vertical inserted sheet 1, another is parallel inserted sheet 2, vertical inserted sheet 1 and parallel inserted sheet 2 T-shaped states, vertical inserted sheet 1 is provided with a convex key respectively with parallel inserted sheet 2.Fig. 2 single-phase alternating current supply socket also is a T shape structure corresponding to T shape plug, and jack, the reed of T shape socket is T shape attitude, and the vertical inserted sheet 1 of the vertical jack 3 of T shape socket and parallel jack 4 and T shape plug is corresponding with parallel inserted sheet 2.When T shape plug inserts T type socket, vertical inserted sheet 1 is vertical insertion with vertical jack 3, parallel inserted sheet 2 is parallel insertion with parallel jack 4, a vertical utmost point that inserts is a phase line, one utmost point of parallel insertion is a zero line, it is directed the insertion that this explanation T shape plug inserts T shape socket, simultaneously, vertical inserted sheet 1 injects in the T shape Die for Reeds of Connector Jack 5 (parallel inserted sheet 2 roughly the same), the convex key of T shape plug slice 1 and the gib key of reed 5 are matched (as shown in Figure 3), at this moment, T shape plug slice 1 increases with the contact-making surface of T shape Die for Reeds of Connector Jack 5, after T shape plug injects T shape socket, T shape plug cross stressed (as shown in Figure 4), like this, difficult drop-off between T shape plug and the T shape socket, and contact is reliable.

Claims

1, the utility model single phase alternating current power supply plugs and sockets, it is characterized in that plugs and sockets designs a T shape structure, the T-shaped state of the inserted sheet of plug, a vertical inserted sheet, another is parallel inserted sheet, with the corresponding receptacle sockets of plug slice, the also T-shaped structure of reed, the vertical inserted sheet of plug T shape inserted sheet has a convex key respectively with parallel inserted sheet, and socket T shape reed has a gib key respectively, during plug insertion socket, a vertical utmost point that inserts is a phase line, one utmost point of parallel insertion is a zero line, in the plug slice socket reed, the convex key of inserted sheet and the gib key of reed is matched simultaneously.

2, single phase alternating current power supply plugs and sockets according to claim 1, it is characterized in that the convex key of plug T shape inserted sheet and the gib key of socket T shape reed match, its both contact area increases, after making T shape plug insert T shape socket, T shape plug cross is stressed, cause difficult drop-off between plug and the socket, contact is reliable.

3, single phase alternating current power supply plugs and sockets according to claim 1 is characterized in that plug insertion socket is directed the insertion, makes phase line and zero line the two poles of the earth be difficult for misplug, thereby has avoided the accident that should not take place in a sense.
