Abstract

A self contact type socket and plug which have excellent contact and convenient usage are provided, which comprise a socket casing and a plug casing, wherein two rotating shafts which oppositely rotate in left and right are arranged in the socket casing, a fixing contact strip is fixed on the rotating shaft, and a permanent magnet is fixedly connected with the fixing contact strip, the rotating shaft is relatively rotated with a moving contact strip, a permanent magnet or an iron strip is fixed on the moving contact strip, and is corresponding to the permanent magnet, contacts are fixed on the plug casing in left and right, and the end portion of the contacts are in circular or are slanted outwards to form a reversed-V shape. The outer ends of the fixing contact strip and the movable contact strip are both slanted outwards to form a reversed-V shape. The rotating shafts in the utility model can freely rotate, can enlarge the scope of finding contacts when inserting the plug, and can tightly clamp the contacts.

Description

Self-contact type socket and plug

Technical field

The utility model relates to a kind of socket and plug, relates in particular to a kind of self-contact type socket and plug.

Background technology

The conventional socket of using all is made up of copper sheet, the spring of plastic casing, compression moulding at present; Plug all is made up of two electrode slices of plastic casing and wiring; Traditional socket plug all is to adopt the screw fixing cord, when wiring, do not have slightly and tightly will cause loose contact, and traditional socket plug the loosening phenomenon of socket intermediate plate occurs easily through long-term use, when making electrical appliance, particularly during high-power electric appliance, can generate heat because contact is unreal, cause socket scaling loss or appliance plug scaling loss.When the indoor and outdoor mobile operating, traditional plugs and sockets can disconnect because peg graft not firm, makes troubles to the worker.

Summary of the invention

The purpose of this utility model provides that a kind of socket can well contact with plug, self-contact type socket and plug easy to use.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of self-contact type socket and plug, comprise Socket casing, plug body, it is characterized in that: correspondence two rotating shafts that have been rotatably connected relatively about in the Socket casing, be fixedly connected with fixed touch plate on the rotating shaft, be fixedly connected with permanent magnet on the fixed touch plate, movable contact flat relatively has been rotatably connected on the rotating shaft, be fixedly connected with permanent magnet or iron plate on the movable contact flat, permanent magnet or iron plate are corresponding with permanent magnet; Correspondence is fixedly connected with contact about on the plug body, and contact end is circular or outward-dipping, forms " eight " word shape.

According to described self-contact type socket and plug, it is characterized in that: the outer end of fixed touch plate and movable contact flat is all outward-dipping, forms " eight " word shape.

Rotating shaft in the utility model is free to rotate, when inserting plug, can enlarge the scope of seeking contact,, therefore contact tightly can be clamped owing to have the suction-combining force all the time between fixed touch plate and the movable contact flat, socket can well be contacted with plug, easy to use.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described:

A kind of self-contact type socket and plug, as Fig. 1, Fig. 2, shown in Figure 3, comprise Socket casing 2, correspondence two rotating shafts 1 that have been rotatably connected relatively are fixedly connected with fixed touch plate 5 about in the plug body 7, Socket casing 2 on the rotating shaft 1, be fixedly connected with permanent magnet 3 on the fixed touch plate 5, the movable contact flat 6 that has been rotatably connected relatively on the rotating shaft 1 is fixedly connected with permanent magnet or iron plate 4 on the movable contact flat 6, permanent magnet or iron plate 4 are corresponding with permanent magnet 3; Correspondence is fixedly connected with contact 8 about on the plug body 7, and contact 8 ends are circular or outward-dipping, form " eight " word shape.In the present embodiment, the outer end of fixed touch plate 5 and movable contact flat 6 is all outward-dipping, forms " eight " word shape.

In order to protect the steadiness of positive plug, the contact shape of plug is designed to circular or outward-dipping, forms " eight " word shape, prevents that effectively plug from coming off, and guarantees well contact.Insert socket smoothly in order to protect positive plug, fixed touch plate and movable contact flat form the outer shape of dehiscing, and the rotating shaft of two contacts divides in housing and stands up the peaceful dual mode of putting, and forms vertical rotation and horizontal rotation installation.The contact front end of plug is bigger than terminal.

Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection range of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.

The utility model in use, when the plug socket, because rotating shaft and Socket casing are to be rotationally connected, pinning plug that can maximum magnitude, and the suction-combining force is arranged between fixed touch plate and the movable contact flat, can contact by the tighter more steady plug and socket that makes.The contact front end of plug is big, can make fixed touch plate and movable contact flat effectively lock plug, makes the plug difficult drop-off.In addition, ordinary plug used in everyday also can insert socket, and closely contacts with movable contact flat with fixed touch plate.

Because rotating shaft of the present utility model and Socket casing are to be rotationally connected, and fixed touch plate, movable contact flat and rotating shaft also are rotationally connected, between two contacts the suction-combining force is arranged, so contact can search out header contact easily, and contact is clamped tightly, guarantee well contact, safe in utilization, convenient, and durable, increase the plug number of times.

Claims

1, a kind of self-contact type socket and plug, comprise Socket casing (2), plug body (7), it is characterized in that: correspondence two rotating shafts (1) that have been rotatably connected relatively about in the Socket casing (2), be fixedly connected with fixed touch plate (5) on the rotating shaft (1), be fixedly connected with permanent magnet (3) on the fixed touch plate (5), movable contact flat (6) relatively has been rotatably connected on the rotating shaft (1), be fixedly connected with permanent magnet or iron plate (4) on the movable contact flat (6), permanent magnet or iron plate (4) are corresponding with permanent magnet (3); Correspondence was fixedly connected with contact (8) about plug body (7) was gone up, and contact (8) end is circular or outward-dipping, forms " eight " word shape.

2, self-contact type socket according to claim 1 and plug is characterized in that: the outer end of fixed touch plate (5) and movable contact flat (6) is all outward-dipping, forms " eight " word shape.
