Utility model content
The purpose of the utility model is to provide a kind of switch improved safety sockets, solve asking for common socket protection against electric shock Topic.
In order to achieve the above object, the technical scheme adopted by the utility model is a kind of switch improved safety socket, Including insulating base frame, it is provided with master switch and multiple groups switch contacts in the insulating base frame, and every group of switch contacts are and institute It states master switch to be connected in parallel by power supply line, every group is also respectively provided with branch switch between switch contacts and master switch;Every group Switch contacts include multiple jacks, and the inside of each jack is embedded with copper sheet, the bottom of jack be provided with it is described The static contact of copper sheet electrical connection, is slideably extended with insulating bar in the static contact, is set with spring on the insulating bar, The upper end of the spring is connected to the bottom side of static contact, and insulating bar bottom is provided with attachment base, the side setting of the attachment base There is movable contact spring, the movable contact spring is electrically connected with corresponding branch switch, and when insulating bar is pressed down, movable contact spring and static contact phase Contact.
The technical solution of the utility model also has the following characteristics that
Switch contacts described in multiple groups include two receptacle contacts switch and three receptacle contacts switch.
The quantity of two jackswitch is two, and the quantity of the three receptacle contacts switch is one.
The upper end of the insulating bar is provided with pushing block.
The spring is extension spring.
The beneficial effects of the utility model are: the switch improved safety socket of (1) the utility model, can effectively improve slotting The safety of seat prevents accidentally touching jack (such as children's touching, liquid or metallic foreign body entrance) electric shock, the protection of isolation electric arc from making 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 Bar 9 moves downwardly together, and stretcher strain occurs for spring 10.It is separately turned on corresponding branch switch 2 and master switch 6 later, accordingly Switch contacts i.e. be powered.
It also should be noted that some point can be operated using the switch improved safety socket of the utility model Zhi Kaiguan 2 powers off corresponding electrical equipment, the energized state without will affect other electrical equipments.
Wherein, every group of switch contacts and corresponding branch switch are the global facility of a relative closure, when power supply is connected Or when plug insertion, the sheet metal contact portion of jack and plug does not generate electric arc, has very high safety and convenience.
