With；(2) the switch improved safety socket of the utility model, can be improved the convenience of socket, selects pass hull closure as needed
Power supply realizes the purpose for saving electric energy.
Detailed description of the invention
Fig. 1 is a kind of top view of switch improved safety socket of the utility model；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is the attachment structure schematic diagram of two receptacle contacts switch and its branch switch in Fig. 1.
In figure, 1. insulating base frames, 2. branch switches, 3. 3 receptacle contacts switch, 4. liang of receptacle contacts switches, 5. power supplys
Line, 6. master switch, 7. copper sheets, 8. pushing blocks, 9. insulating bars, 10. springs, 11. attachment bases, 12. static contacts, 13. movable contact springs.
Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
As depicted in figs. 1 and 2, a kind of switch improved safety socket of the utility model, including insulating base frame 1, it is described
Master switch 6 and multiple groups switch contacts are provided in insulating base frame 1, and every group of switch contacts pass through power supply line 5 with master switch 6
It is connected in parallel, is also respectively provided with branch switch 2 between every group of switch contacts and master switch 6.
As shown in figure 3, every group of switch contacts include multiple jacks, the inside of each jack is embedded with copper sheet 7,
The bottom of jack is provided with the static contact 12 being electrically connected with the copper sheet, is slideably extended with insulating bar in the static contact 12
9, spring 10 is set on the insulating bar 9, which is extension spring, and the upper end of the spring 10 is connected to static contact
12 bottom side, 9 bottom of insulating bar are provided with attachment base 11, and the side of the attachment base 11 is provided with movable contact spring 13, the dynamic touching
Piece 13 is electrically connected with corresponding branch switch 2, and when insulating bar 9 is pressed down, movable contact spring 13 is in contact with static contact 12.
This switch improved safety socket of the utility model, total design principle are carried out often by two-stage switch
The control of group switch contacts, i.e. level-one are master switch 6, and second level is each branch switch 2, and wherein master switch 6 is on the whole to all
Plug switch and the closure of branch switch controlled, and each branch switch 2 only controls corresponding switch contacts.
It is ensured that master switch 6 and each branch switch 2 are in the state closed, Zhi Houzai before the plug insertion of electrical equipment
When will be inserted into corresponding jack, the side of plug is in contact with the copper sheet 7 in jack, hereafter as plug gos deep into, plug
The upper-end contact of lower end and insulating bar 9, insulating bar 9 can move downward under the effect of the pressure, and movable contact spring 13 is driven to move down, until
It is in contact with movable contact spring 13 with static contact, at this time in the state being powered between each jack, spring 10 is also with insulation at the same time
