Abstract
The utility model relates to a single-phase power supply plug, which is characterized in that the width and angle of the plug pins are adjustable, and the plug is loose when inserting and pulling, but tight after inserting. The utility model is composed of a casing, screw nails, plug pins, and a spring. The casing is split into left and right casings. The front ends of the right casing (1) and the right casing (8) are connected with the connection mode of universal joint. The lower ends of the left and right casings are both provided with a spring seat (9), and the spring (10) is arranged between the two spring seats (9). The utility model has the advantages of simple structure and ease realization. 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 suitable for any place needing plugs.
Description
The utility model relates to technical field of electric appliances, and exactly it is a kind of single phase poaer supply plug.
Attaching plug is a kind of a kind of electric elements that often use in industry 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 tension.The latter is owing to the production of disposal molding, and 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 produces 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, it is usually said " scintillation " phenomenon, " scintillation " this phenomenon harm is very big, 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 designs very tightly, and 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 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 inconvenience in addition, owing to 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 housing, screw, pin and spring, it is characterized in that: housing is divided into left and right sides housing, left shell (1) adopts the universal joint connected mode to be connected with right shell body (8) front end, all there is a spring base (9) housing lower end, the left and right sides, spring (10) pin (3), (5) is housed between two spring bases (9) fixes with screw (4) in housing
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, is difficult for sparking and short circuit phenomenon take place, and can replace existing attaching plug.
Below in conjunction with drawings and Examples the utility model is done further detailed description
Fig. 1 is a structural representation of the present utility model
1 is left shell among the figure, and 2 is screw, and 3 is pin, and 4 is screw, and 5 is pin, and 6 is steering base, and 7 is steering ball, and 8 is right shell body, and 9 is spring base, and 10 is spring.
The production technology of manufacturing process of the present utility model and existing power supply plug is basic identical, just two housings adopts the universal joint connected mode to connect, a spring is equipped with in the rear end, housing adopts injection molding, get all the ready shown in the accompanying drawing behind the parts, with reference to accompanying drawing assembling should note in the time of can producing two pins between distance without prejudice to the regulation of national standard.During use, the effect owing to Rear springs behind the plug insertion socket will make the reed in pin and the socket fit together closely, thereby be difficult for taking place " scintillation " phenomenon.As insert "
" during the formula socket, because two housings adopts the universal joint connected mode, modification more easily takes place plug, thereby a little firmly can plug casing is slightly crooked, make it to be adapted to "
The formula socket.Because modification is housing itself, and housing separates, be fixed on the power line on the pin and do not stress, thereby power line can not fracture, more can not take place to strike sparks and short circuit phenomenon.
Claims (2)
1, single phase poaer supply plug, it is made up of housing, screw, pin and spring, it is characterized in that: housing is divided into left and right sides housing, left shell (1) adopts the universal joint connected mode to be connected with right shell body (8) front end, all there is a spring base (9) housing lower end, the left and right sides, and spring (10) is housed between two spring bases (9)
2, single phase poaer supply plug according to claim 1 is characterized in that: pin (3), (5) are fixing with screw (4) in housing
