Abstract
The utility model relates to a self-fastening single-phase power supply plug. The width and angle of the plug pins are adjustable, which is characterized in that the plug pins are loose when inserting and drawing, and tight after inserting. The utility model is composed of plug pins, a casing, screw nails, and conducting wire. The front end of the casing (4) is provided with a thin wall connector (7). The back end of the casing (4) is provided with two spring fixing seats (2), and a spring (3) is arranged between the two fixing seats. The rest part of the casing (4) is hollow. The utility model has the advantages of simple structure and high safety. The utility model is applicable to a two-foot socket as well as a three-foot type socket, and is connected with the socket tightly. The utility model is especially suitable as the power cord for TV sets, voice recorders, etc.
Description
The utility model relates to technical field of electric appliances, and exactly it is a kind of self-tightening type single phase poaer supply plug.
Attaching plug is a kind of a kind of electric elements that often use in industrial and domestic life.At present, the plug of selling on the market is of a great variety, have two-phase, three-phase, flat formula plug, garden formula plug, turnover or the like, but the Single-phase plug that uses in the daily life has two kinds basically: a kind of user of being is the single plug from purchasing on the market on demand; A kind of be the plug of the disposal molding that together brings of the power line with the electrical equipment of being purchased the former is easily loosening owing to the heterogeneity of producing and other reason pin, or the tension latter is because the production of disposal molding, two pins are fixing dead, so the pin tension.No matter be pine, or tension they a lot of drawbacks are all arranged.If pin is loose excessively, can make that to insert the back insecure, thereby with the sheet metal loose contact of socket, easily produce sparking, or virtual connection is touched and is formed excessive resistance; Time has been grown the coupled lead of pin is fractureed in addition, thereby produce short circuit or sparking, if pin tension, loosening with the pin that can make of a specified duration, in addition when the shared socket of several plugs, when some plugs insert or extract, other plug generation temporarily or is fully opened circuit, be usually said " scintillation " phenomenon, " scintillation " this phenomenon harm is very big, and especially the picture tube harm to television set is bigger.For fear of the loosening drawback of being brought of pin, metal contact in a lot of sockets on the market, design very tightly, especially a kind of socket of " travelling contact type " that cries is tighter, though this has overcome the loosening drawback of pin to a certain extent, but it is because too tight, make when inserting and pulling up all very hard, have in addition can not insert fully, this has brought difficulty and dangerous to use, especially use and electrical equipment breaks down suddenly when needing emergency power off as child, more dangerous and inconvenient.In addition, because tension, the easier fixing plug of pin that makes damages, thus produce the present normally used plug of series of malpractice insert only "
Formula and "
A kind of in the formula jack, insert only mostly "
" the formula jack, this has greatly limited the use of user to electrical equipment, and the someone has designed the plug that can insert different jacks for this reason.But this plug is except having this new function, not only still there is plug to cross outside the drawback of pine or tension, also produced new defective, because pin frequently changes, its easier coupled lead of pin that makes fractures, thus easier sparking, short circuit, this in addition plug can not disposablely be produced, therefore can not be promoted the use of widely, and, during assembling than ordinary plug complexity.
The purpose of this utility model provides a kind of limb width and angle all can be adjusted, and when plug pine, insert the tight new-type self-tightening type single phase poaer supply plug in back.It is not only simple in structure, and is easy to use, and safe and reliable.
The purpose of this utility model is achieved by the following scheme, it is made up of pin, housing, screw and lead, it is characterized in that: housing (4) front end has a thin-walled connector (7), housing (4) rear end has two spring fixed seats (2) relatively, spring (3) is housed between two holders, and remainder is hollow in the middle of the housing (4).
The utility model has the advantages that: pin width and adjustable angle, both applicable to "
" the formula socket, again applicable to "
The formula socket, and when plug pine, it is tight to insert the back, thereby tight with being connected of socket.Simple in structure, safe and reliable, be fit to disposable production, be particularly suitable for the power line of household electrical appliance such as television set, recorder.
Below in conjunction with drawings and Examples the utility model is done further detailed description.
Fig. 1 is the utility model structural representation
1 is power line among the figure, and 2 is spring fixed seat, and 3 is spring, and 4 is housing, and 5 is screw, and 6 is pin, and 7 is the thin-walled connector
The production technology of manufacturing process of the present utility model and existing single phase poaer supply plug is basic identical, just the housing middle part is empty substantially, there is a thin-walled connector to connect at front end, a spring is equipped with in the rear end, be placed on single injection-molded in the mould after during production power line and pin being connected, at last spring loaded onto the distance that to note in the time of to produce between two pins regulation without prejudice to national standard.During use, behind the plug insertion socket, because the effect of Rear springs will make tighter that pin is connected with socket.As insert "
" during the formula socket, because centre of the present utility model is empty substantially, plug more easily deforms, thereby it is slightly crooked with plug exert oneself a little, can make the plug adaptation "
" the formula socket
