Abstract
The utility model relates to a universal single-phase two-polar power-supply plug for the daily electrical appliance, particularly a plug for automatically changing the pin pole angle, which can rotate the plug pole angle. Flat inserting pieces whose heads are in the circle arc shape are arranged in fan-shaped holes on a shell. The gaps of the flat inserting pieces are matched with lug bosses on the hole walls of the fan-shaped holes on a shell. When the circle arc-shaped heads of the flat inserting pieces are inserted into the fan-shaped holes, a flat plug is forced to automatically rotate, and the use on a two-polar socket and a three-polar socket is realized. The utility model has the advantages of simple structure, easy manufacture and low cost.
Description
The utility model is general single-phase two utmost point attaching plugs of a kind of household appliance, particularly can rotate the plug that the polar angle degree is inserted in the automatic conversion of inserting the polar angle degree.
Individual event two utmost point flat plugs that use on the existing household appliance, owing to can not use on three pole sockets, this makes troubles just for the use of household appliance under certain occasion of using the two poles of the earth flat plug.The angle that plug is inserted the utmost point has appearred changing for addressing this problem, make plug can with the CN88211266.X of two pole sockets and three pole socket compatibilities, " two, Three-hole socket common pin " patent, its structure is to have a circular shaft on the metal insert of plug, realizes that by circular shaft the metal insert rotational angle adapts to two kinds of different sockets.Its weak point is that manufacturing process is complicated, has increased manufacturing cost owing to have a rotating shaft on metal insert.
The purpose of this utility model is to provide a kind of automatic conversion to insert the plug of polar angle degree, and not only simple in structure, cost is low, and the angle that can rotate metal insert easily realizes the function that patches to single-phase two pole sockets and single-phase three pole socket compatibilities.
The utility model is achieved in that automatic conversion inserts the plug of polar angle degree and mainly be made up of the flat inserted sheet of housing and the two poles of the earth, the head of flat inserted sheet is circular arc, its middle part punching press is jagged, the hole that housing cooperates with flat inserted sheet is a scallop hole, is being provided with the boss that matches with breach on the flat inserted sheet on the hole wall of housing scallop hole.Because the breach on every extremely flat inserted sheet matches with the boss on the fan-shaped hole wall of housing, avoided flat inserted sheet indexing to cause the possibility of rocking and deviating from, the head of flat plug circular arc is when inserting the jack of socket, the head of circular arc can play guide effect, force flat plug to turn to automatically, adapt to the needs of jack angle on the socket, this utility model structure is simple especially, handling ease, cost is low.
Below in conjunction with accompanying drawing the utility model is further described.Fig. 1 is the plug A-A cutaway view that the polar angle degree is inserted in conversion automatically, and Fig. 2 is the plug side view that the polar angle degree is inserted in conversion automatically, and Fig. 3 is the plug B-B cutaway view that the polar angle degree is inserted in conversion automatically.
Automatically the plug of the slotting polar angle degree of conversion is made up of the flat inserted sheet of housing (1) and the two poles of the earth (2), the head of flat inserted sheet (2) is circular arc, its middle part punching press has the breach of symmetry, the hole that housing (1) cooperates with flat inserted sheet (2) is a scallop hole, and the boss that respectively is provided with in the upper and lower on the fan-shaped hole wall of housing (1) on the fan-shaped hole wall of breach that boss, every extremely flat inserted sheet (2) go up symmetry and housing (1) matches.The spacing angle of flat inserted sheet (2) rotation is limited by the scallop hole of housing (1), thereby make two extremely flat inserted sheets (2) can be in parallel respectively or be the position of 60 ° of angles, the plug that makes automatic conversion insert the polar angle degree can be realized the compatibility to two pole sockets and three pole sockets, when being in, the flat inserted sheets in the two poles of the earth (2) can be used for two pole sockets when parallel, when going to the flat inserted sheets in the two poles of the earth (2) angle when being 60 °, can be used for three pole sockets.
Claims (3)
1. change the plug of inserting the polar angle degree automatically for one kind, mainly form by the flat inserted sheet of housing (1) and the two poles of the earth (2), the head that it is characterized in that flat inserted sheet (2) is circular arc, its middle part punching press is jagged, the hole that housing (1) cooperates with flat inserted sheet (2) is a scallop hole, is being provided with the boss that matches with breach on the flat inserted sheet (2) on the hole wall of housing (1) scallop hole.
2. the plug of polar angle degree is inserted in automatic conversion according to claim 1, it is characterized in that the breach of the breach of flat inserted sheet (2) middle part punching press for symmetry.
3. the plug of polar angle degree is inserted in automatic conversion according to claim 1, it is characterized in that the upper and lower on the hole wall of housing (1) scallop hole respectively is provided with boss.
