Abstract

The utility model relates to a plug adaptive to jack shape. The plug comprises pins respectively formed by a bundle of magnetic metal strips through mutual magnetic force attraction; the metal strips on the outmost layer of each pin is an elastic hollow pipe; and the external diameter of the top portion is less than that the external diameter of the pipe body. When applied with outside force, the pins can change the position of the metal strips in order to change cross section of the pins; when the pins are inserted into power supply jacks with different shapes, the pins are extruded by the jack walls to change the cross section shape at will, so as to adapt to jacks with different shapes.

Description

The plug of self adaptation jack shape
Technical field
The utility model relates to the expansion field of pin function, relates in particular to a kind of plug of self adaptation jack shape.
Background technology
Plug is the accessory of each electric equipment products basically, and ordinary circumstance has the electrical equipment of the demand of electricity all to need to obtain power supply by plug gang socket.Along with electrical equipment is popularized, for consumers in general make the electrical appliance facility, the socket and plug that market produces makes the socket plug specification unified day by day towards standardization, causes and can not behaviour in service take place because plug is unworthy of socket to avoid electrical equipment.Yet, owing to multiple reasons such as national boundaries, use habit, electrical equipment oneself requirements, make appliance socket might not mate each plug, therefore plug can't insert, causing electrical equipment to use, therefore how to avoid the generation of this situation, then is a problem that is worth solution.
Summary of the invention
Appliance plug can be suitable for various sockets for convenience, the utility model proposes a kind of plug of self adaptation jack shape.The plug of self adaptation jack shape, this plug is formed pin by a branch of magnetic bonding jumper by mutual magnetic attraction, thereby the position that can change bonding jumper when this pin is subjected to external force changes the cross section of pin, when pin was inserted in the difform supply hub, the extruding that pin is subjected to Socket walls can change cross sectional shape arbitrarily to adapt to difform jack.
The outermost bonding jumper of the pin of self adaptation jack shape plug is elasticity hollow pipe, and the head portion external diameter is less than the body external diameter.When inserting in the supply hub like this, whole pin inserts easily, and outermost bonding jumper extrusion, and pipe is deformed into elliptical tube, and with the Socket walls jam-packed, whole pin is not easy to come off.
The plug of self adaptation jack shape, bonding jumper external diameter are 0.5mm ~ 1.2mm.The meticulous easy deformation of bonding jumper is unfavorable for long-term use; The words that bonding jumper is thick excessively then can't adapt to the trickle adjustment of different jacks.The utility model is in order to reach ideal effect, and the bonding jumper external diameter of the plug of self adaptation jack shape is decided to be 0.8mm.
Further technological improvement of the present utility model, the bonding jumper magnetic intensity of the plug of self adaptation jack shape is 0.3T ~ 0.9T.The magnetism intensity of bonding jumper is too small, and bonding jumper attraction each other is not up to standard, then is difficult for fixing the shaping, forms the plug of being convenient to insert jack; The magnetism intensity of bonding jumper is excessive, then in use runs into when needing to adjust the pin cross section to require great effort very much, uses inconvenient.The utility model is in order to reach ideal effect, and the bonding jumper magnetic intensity of the plug of self adaptation jack shape is decided to be 0.7T.
The utility model has been obtained following technique effect:
By the utility model plug is improved, the fixing metal pin that is shaped of common socket is designed to rely on the disposable pin of magnetic force, cost increases not obvious, has brought facility for the user makes electrical appliance, has avoided socket and plug not match and has caused electrical equipment can't use phenomenon.
Description of drawings
Fig. 1 is the plug schematic diagram of self adaptation jack shape of the present utility model;
Fig. 2 is the plug conversion schematic diagram of self adaptation jack shape of the present utility model.
Embodiment
Understand and enforcement the utility model for the ease of those of ordinary skills, below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Embodiment:
The utility model discloses a kind of design of plug of self adaptation jack shape, see Fig. 1, comprise plug 1 body.The pin 2 of plug is by a branch of bonding jumper, and bonding jumper has magnetic, can attract each other, and the external diameter of bonding jumper is 0.8mm, and outermost bonding jumper is elasticity hollow pipe, and the head portion external diameter is less than the body external diameter.When inserting in the supply hub like this, whole pin inserts easily, and outermost bonding jumper extrusion, and pipe is deformed into elliptical tube, and with the Socket walls jam-packed, whole pin is not easy to come off.The magnetic of bonding jumper is 0.7T.Thereby this pin 2 can change the cross section that the position of bonding jumper changes pin 2 when being subjected to external force, when pin 2 is inserted in the difform supply hub, the extruding that pin 2 is subjected to Socket walls can change cross sectional shape arbitrarily to adapt to difform jack, using receptacle sockets generally speaking is rectangular eyelet, when inserting jack, the plug of self adaptation jack shape becomes cuboid according to the eyelet shape conversion, as Fig. 1.When jack was circle, the plug of self adaptation jack shape also can change pin 2 and change over cylindrical shape, as Fig. 2, to adapt to various jacks according to the jack changes shape.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
