Abstract

The utility model relates to a plug and a socket with buckle structures for a power supply. Clamping springs are added to the outsides of two plugging reeds of the plug, and a shell of a socket is used as a clamping tongue; the firm and reliable connection can be obtained by using clamping grooves on the clamping springs to buckle the clamping tongue after the plug is plugged into the socket, so that the plug can be prevented from falling off from the socket to cause a power failure. The buckle structures are matched with the tension of a bottom spring of the socket, so well contact between the plug and the socket can be ensured after the plug is plugged into the socket. The rigid plastic clamping spring of the plug can exert the function of a protecting cover, and the power supply can be switched on as long as the plugging reeds contact with the bottom spring as the plug is completely plugged into the socket in the main, so that double security protection of electric shock prevention as operating can be obtained.

Description

The clip type power supply plug socket

The utility model relates to a kind of plug and socket of power source that has buckle structure.

At present, general plug and socket of power source is to clamp the both sides of plug stamen sheet and realize connecting by two inside tension force of reeds in the socket.One, because Die for Reeds of Connector Jack is erect outwardly, and the plug insertion socket stroke is oversize and plug stamen sheet is exposed fully, when plug insertion socket, energized during plug stamen sheet one contact base reed, the hidden danger that finger gets an electric shock when existing operation.Two, owing to insert repeatedly for a long time and extract, and the high temperature that causes because of loose contact, make the inside tension force of Die for Reeds of Connector Jack weaken and press from both sides tight plug stamen sheet, cause plug from socket, to come off at an easy rate, cut off the electricity supply with causing the accident character.Three, because plug stamen sheet and Die for Reeds of Connector Jack are contacts side surfaces, when Die for Reeds of Connector Jack tension force weakens and presss from both sides tight plug stamen sheet or when loosening fully, the area of passage that plug contacts with socket reduces and causes loose contact, can cause high temperature and produce spark, even cause fire.

The purpose of this utility model provides a kind of plug and socket of power source that has buckle structure, guarantees the firm and reliable connection of plug and socket and does not come off; Also rely on the tension force of socket back spring to withstand pin head and guarantee that the plugs and sockets contact is good simultaneously; And with jump ring when guard shield with change the contact site of plugs and sockets energized and the duplicate protection of protection against electric shock when realizing operating.

The purpose of this utility model is achieved in that

The outside of two slotting springs of plug respectively has one to mould jump ring firmly, and the jump ring root has a draw-in groove.Spring at the bottom of the socket back horizontal positioned, socket cover are the block tongue of buckle.During with plug insertion socket, mould firmly jump ring prop up socket upper casing hole along the extruding jump ring draw close to slotting spring; After plug inserted socket fully, jump ring was opened outward, and draw-in groove fastens socket cover, thereby realized solid and reliable connection.End spring guarantees that by the head that its tension force upwards tightly props up the slotting spring of plug contact is good.Plug is inserted spring to be had and moulds jump ring firmly and work as guard shield; and only just spring and energized at the bottom of the contact base after plug inserts socket substantially fully; that is to say the contact site that has changed plug and socket energized, thereby realized preventing when operating the dual security protection that finger gets an electric shock.

The utility model increases buckle structure, changes plugs and sockets energized contact site, realizes dual electrical shock protection safety.Be further described below in conjunction with accompanying drawing.

Among Fig. 5: 7, socket back spring.

In Fig. 1, it is the rectangle cylinder that plug is inserted spring (4), and tack, head have overcurrent sectional area up to specification.The outside of two slotting springs of plug (4) respectively has one to mould jump ring (3) firmly.Moulding jump ring (3) firmly is the rectangle reverse taper, and between the slotting spring (4) distance is arranged.Mould jump ring (3) firmly and slightly be shorter than slotting spring (4).Mould jump ring (3) firmly and form a draw-in groove (2) because of reverse taper by the plug top.Notch is following to be the jump ring tongue, and the guiding plug inserts socket smoothly, and protection does not expose outside inserting spring (4) yet.Spring at the bottom of the socket back horizontal positioned (7) is seen Fig. 4, Fig. 5.End spring (7) arches, and can open pressure.Socket back spring (7) open the pressing behind the stroke to the height on socket cover table plane and the stroke of plug insertion socket of half that be depressed matches.Socket cover is seen Fig. 3, and its lid shell is the block tongue of buckle, and the height that the thickness of shell and plug are moulded the draw-in groove (2) of jump ring (3) firmly matches.Plug location notch (5) is arranged in the socket cover, see Fig. 2, Fig. 3.(6) are pricked for socket plug among Fig. 2, and the distance between its size and the Kong Yukong matches with plug.During plug insertion socket, insert spring (4) and socket positioning groove (5) in, aims at end spring (7) insertion, mould jump ring (3) conical surface firmly and prop up socket upper casing hole and draw close to slotting spring (4) along pushing jump ring (3); After plug inserts socket fully, mould outer of jump ring (3) firmly, draw-in groove (2) fastens socket cover, thereby realizes solid and reliable connection.End spring (7) tightly props up the head that plug is inserted spring (4) by its tension force, guarantees that contact is good.Plug is inserted spring (4) to be had and moulds jump ring (3) firmly and work as outer cover; and energized just when plug inserts socket substantially fully only; that is to say the contact site that has changed old-fashioned plug and socket energized, thereby prevent that finger touch from causing the dual security protection that gets an electric shock to slotting spring (4) when having realized operation.

Disconnect when connecting, depress the inside extruding of active button (1) of plug both sides gently and mould jump ring (3) firmly, make to mould firmly to pull the plug out of the socket after jump ring draw-in groove (2) breaks away from block tongue (jack housing).

The utility model structure and operation principle are simple, and be applied widely, alternative general two-pin plug socket, 3-phase plug socket and knockdown multipurpose socket at present, and can realize general exchange.

Claims

1. plug and socket of power source that has buckle structure is characterized in that: the outside of two slotting springs of plug has moulds jump ring firmly and is block tongue with the socket shell, and the jump ring draw-in groove fastens block tongue behind the plug insertion socket, guarantees the plugs and sockets outage that do not come off that is connected firmly.

2. clip type power supply plug socket according to claim 1 is characterized in that: buckle structure cooperates the tension force of socket back spring, and plug contacts well with socket behind the plug insertion socket.

3. clip type power supply plug socket according to claim 1; it is characterized in that: plug is moulded the jump ring guard shield firmly and is inserted spring; simultaneously also only after plug inserts socket substantially fully, plug is inserted just energized of the low spring of spring contact base, the dual security protection of protection against electric shock when realizing operation.
