Abstract

The utility model relates to an anti-drop safety plug and a socket. The two pins of the plug form bent feet in a right angle mode. In addition, the two pins are opposite outwards. The two jacks of the socket are corresponding to the two pins. The two jacks are extended clockwise (or counterclockwise) into half-arc holes. The conductive bodies of the two electrodes are arranged on the opposite face of a socket body and are positioned on both sides of the half-arc holes. After inserted into the socket, the plug is rotated in a certain angle. Thus, the plug and the socket can be tightly contacted without falling off. For the goal that the existing plug is suitable for the socket, a transition-type plug can be used for insertion and connection. The utility model has the advantages of simple structure, convenient use, adequate contact, prevention of falling off, and non-touch accidents for the socket.

Description

Slip-off preventing safety plug socket

The utility model belongs to electrotechnical apparatus, specifically a kind of slip-off preventing safety plug socket.

Along with popularizing of household electrical appliance, the use of plugs and sockets is increasingly extensive, but the plug and socket that generally uses is at aspect and imperfections such as function of use and security protections at present, exist following shortcomings: the one, because plug directly inserts on the socket, can not pin, in use, plug is come off, cause and use inconvenience because of involving as movable electrical appliances; The 2nd, reed in the existing socket or spring easily follow the string because of long-term use, and it is bad to cause pin to contact with reed, flashing and oxidation; The 3rd, outside the electric conductor in the existing receptacle sockets was exposed to, especially to children, electric shock accidents very easily met accident.

The purpose of this utility model is to provide a kind of novel slip-off preventing safety plug socket, and the electric conductor in its receptacle sockets does not expose, and pin contacts well with the interior reed of socket, and pin is the clubfoot shape, can not come off.

By the slip-off preventing safety plug socket that the utility model proposed, it has comprised plug and socket, and two pins of its plug are rectangular clubfoot, and in opposite directions outwardly, point-blank; Two jacks on its socket are corresponding with pin, the inner of each jack is extended for a semi-arcwise hole clockwise or counterclockwise, is beneficial to the pin rotation, and two electrodes conduct bodies are loaded on the reverse side of socket panel, be positioned at the both sides of semi-arcwise hole, electric conductor is not exposed.

Below in conjunction with embodiment the utility model is further described.

Plug and socket of the present utility model is complementary.Plug body (1) is similar with existing plug body, and the pin of its lower end (2) is the clubfoot that is converted into the right angle, and in opposite directions outwardly.Socket (3) also is a block socket panel, on two corresponding jacks (4) are arranged, the jack shape is corresponding with pin, and respectively there is clockwise direction to be extended for an arc hole, be beneficial to be rotated after pin inserts, reverse side at socket panel, in the both sides of semi-arcwise hole an electrodes conduct body (5) is housed respectively, general available copper reed is manufactured, and an end is fixed on the socket panel by screw (6), and the other end is bent slightly and embedded in the socket panel, the thickness of socket panel is h, the distance that it and plug clubfoot partly arrive plug body equates that substantially copper reed is installed a little more than socket panel, makes the thickness of itself and socket panel addition be slightly larger than h, the interference fit that this is small, after plug inserts rotation, can rely on the intrinsic elasticity of plug and socket material, reach the purpose of locking and abundant contact.

During use, the plug alignment socket is inserted downwards, the dextrorotation certain angle can be locked then, because plug base pin has bent angle, plug promptly is stuck in the socket after rotation, can not directly dial down.Because conducting strip is loaded on the socket bottom, from jack, can not directly contact, so can avoid having an accident because of directly touching socket.

Because the plug base pin of existing product is not a clubfoot at present, as promotes socket of the present utility model, existing plug is inapplicable, also is impossible and will change original plug fully.A kind of transiens plug is now proposed, as shown in Figure 4, in rectangle transition plug body (8), two plug-in parts (10) are housed, the upper end has jack to lead to plug-in part, and its lower end is the clubfoot pin that stretches out, and will have plug (7) now and insert, the pin of its plug (7) inserts from the upper end jack in the plug-in part of transition plug, and such transition plug is with regard to satisfying and this practical socket adapted.For existing plug 7 and transition plug are connected together, not easily separated, can use the aluminium dog (11) of T shape to fix, the aluminium dog is fixed on the transition plug by the fixing hole on the plug body (9) with bolt, nut earlier, the top horizontal stripe with the aluminium dog encases existing plug, clamp then.

The utility model is simple in structure, and is easy to use, can prevent that plug from coming off, because electric conductor does not expose in the jack, and the socket touch accident that can not meet accident.
