Description
Technical field
The utility model relates to a kind of earth leakage protective socket, refers to especially that a kind of dynamic/static contact contact stabilization is reliable, low cost of manufacture, simple, the earth leakage protective socket stable and reliable operation new type electric leakageproof socket of processing technology.
Background technology
Earth leakage protective socket of a great variety, structure is different.As the patent No. is Fig. 4 of 00250313.1 patent application and shown in Figure 2.One end of the power supply input flexibility sheet metal 20,21 that it links to each other with power supply input wires screw 9,10 is respectively equipped with moving contact 22,23 (shown in Figure 1 as the application); This is to moving contact 22,23 and be arranged on fixed contact 16,15 corresponding (shown in Figure 2 as the application) on the power supply output metallic conductor 14,13 of middle layer bracket 3 both sides; contact or disconnection; thereby the power input of realization earth leakage protective socket is connected with output electric power or disconnects.
Along with the development of earth leakage protective socket, application number is that 200480006646.5 patent applications also disclose a kind of supply socket.Shown in Fig. 3, Fig. 4 (Fig. 3 of the application, Fig. 4) of this application, in the disclosed supply socket of this patent application, one end of the sheet metal 66,64 that links to each other with power input is two fingers, all is connected with electric bridge contact 68,70,72,74 on the end of finger.Shown in Fig. 2 (Fig. 5 of the application) of this application, electric bridge contact 68,70,72,74 on the sheet metal 66,64 contacts with contact 56,58,62,60 on the power supply output sheet metal respectively or disconnects, thereby, the power input that makes supply socket and output realize that electric power is connected or disconnects, and supply socket has power supply to export or non-transformer is exported.
The shortcoming of the supply socket of this structure is:
1, the contact contact is unreal, not firm.Shown in Fig. 3 (Fig. 3 of the application) of 200480006646.5 patent applications, in the process that sheet metal 66,64 moves up and down, often sheet metal 66 takes place is not to move up or down with being the level of state, but move up or down obliquely, an electric bridge contact (as electric bridge contact 68) of very easily causing its finger end has contacted with contact 56 on the power supply output sheet metal, and another electric bridge contact (as electric bridge contact 70) of same sheet metal finger end and power supply are exported contact 58 on the sheet metal and do not contacted or contact unreal; In like manner, also can there be same problem in sheet metal 64, the sound contact occurs and contacts phenomenon unreal, not firm, virtual connection.
2, the supply socket job insecurity is reliable.
Owing to contact unreal, illusive phenomenon with 68,70,72, the 74 frequent contacts 56,58,62,60 that occur exporting on the sheet metal, electric bridge contact on the continuous sheet metal 66,64 of power input with power supply, so, make that the job insecurity of whole supply socket is unreliable.
3, processing technology complexity, manufacturing cost height.
In order to guarantee the stability and reliability of supply socket work, electric bridge contact 68,70,72,74 on the sheet metal 66,64 that must guarantee to link to each other with power input contacts securely with the contact 56,58,62,60 on the power supply output sheet metal is stable simultaneously, so, must improve processing technology, move up and down to guarantee that sheet metal 66,64 can be the level of state, two contacts of its end all with power supply output sheet metal on the contact reliably contact, so processing technology complexity, manufacturing cost height.
In addition, because the end of power supply input sheet metal 66,64 need be provided with two contacts, and sheet metal is in the process that moves up and down, and the contact of to drive its end moves up and down, so, sheet metal 66,64 broads.Because sheet metal 66,64 broads, longer are so consumption is just big, has also increased manufacturing cost.
