General safe socket
The present invention relates to a kind of General safe socket for electric equipment power supply usefulness, be particularly related to a kind of safety socket that can guarantee that the person is not got an electric shock and injures, in the time of among people's mistake will be conducted electricity foreign matter insertion jack, electric shock accidents can not take place; Even two fingers slip into the attaching plug current-carrying part simultaneously during the plug plug, electric shock accidents can not take place yet.
Electric shock accidents in the time of in user's mistake will be conducted electricity foreign matter insertion jack, will take place in normally used supply socket, cause electric shock, even cause loss of life or personal injury; User's two fingers when the plug plug slip into the current-carrying part of attaching plug accidentally in addition, also electric shock accidents can take place.
The safety socket of China children Xu Chen invention has the mechanical trap of covering jack, when plug bipod simultaneously during the roof pressure trap, can open trap.And the insertion jack, energized.This mechanical safety socket, complex structure, bulky, poor reliability is damaged easily.
The objective of the invention is defective, a kind of safe and reliable universal power supply socket is provided at above-mentioned normally used common socket and the existence of machine security socket.
General safe socket of the present invention is provided with an electrical interlocks structure, when in jack, not inserting attaching plug, each jack all not with power connection, have only the plug bipod of working as all to insert jack simultaneously, when arriving near extreme position, each conduction patches just energized of sheet, and electric equipment is started.If user mistake will be conducted electricity foreign matter and be inserted among arbitrary jack, it is not charged that conduction in this jack patches sheet, electric shock accidents can not take place, in the process of plug plug, if when accidentally two fingers being slipped into the current-carrying part that touches plug, electric shock accidents can not take place yet.
Brief Description Of Drawings
Fig. 1 is according to General safe socket generalized section of the present invention.
Fig. 2 is the upward view of A-A direction.
Fig. 3 patches the schematic diagram of sheet energized situation when being safety socket insertion appliance plug.
Accompanying drawings is according to embodiments of the invention.With reference to Fig. 1, Fig. 2 conduction patch sheet (1) and changing-over electrode slice (3) respectively on supporting clapboard (11) and below be riveted on simultaneously on the circular hole (12) on the dividing plate (11) with tubular rivet (14); Conduction patch sheet (2) and changing-over electrode slice (4) respectively on supporting clapboard (11) with below be riveted on the hole (13) with tubular rivet (15).Conduction patches sheet (1) and (2) are separated by the protrusion that is threaded the hole (19) above the supporting clapboard (11).The convex tendon (20) of changing-over electrode slice (3) and (4) weak point below supporting clapboard (11) separates.Insulation depression bar (7) and (8) is through respectively in tubular rivet (14) and (15) hollow, can move up and down flexibly.Power supply wiring sheet (5) and (6), locate and separate by the boss on the base (21), and be fixed on the base (16), its contact (24) and (25) respectively with contact (26) and (27) concentric one group of normally open contact of relative formation (9) and (10) of changing-over electrode slice (4) and (3).Changing-over electrode slice and power supply wiring sheet and conduction patch sheet and all make with whippy good electric conducting material, can guarantee that conduction is good, and have enough elastic force that the insulation depression bar is resetted.The insulation depression bar, power supply wiring sheet and the changing-over electrode slice that is cross-linked constitute the electrical interlocks structure jointly.The base central axis is provided with two thrusts with threaded hole (28) and (29).The supporting clapboard that assembles is screwed on the boss (28) and (29) at insulator foot, and the loam cake (23) that has jack is fixed on the convex platform thing (19) of supporting clapboard with screw (30).
With reference to Fig. 3, when attaching plug (31) the insertion conduction of electric equipment patches sheet, depression bar is arrived near extreme position by roof pressure, the elastic force that overcomes the changing-over electrode slice is pushed the contact of changing-over electrode slice to the contact of power supply wiring sheet, make normally open contact (9) and (10) closed simultaneously, energized can start electric equipment with relative power supply wiring sheet connection by the changing-over electrode slice to patch sheet.Under plug patches "on" position, because patch the elastic restoring force that the elasticity power of seizing on both sides by the arms of sheet is enough to overcome the changing-over electrode slice, and unlikely plug is ejected, guarantee normal power supply.
Obviously, among any conducting objects is inserted arbitrary jack, even depression bar is pushed up extreme position, make corresponding normally open contact closure, it is charged also can only to make another relative conduction patch sheet, and the conduction in this jack patch sheet not with power connection, and electric shock accidents can not take place.When two finger mistakes contacts with the plug bipod because the thickness of pointing makes plug depression bar can not be pushed up the position of necessity, thereby patch sheet also not with power connection, electric shock accidents can not take place.
