Description

Supply unit

[technical field]

The present invention relates to a kind of supply unit, particularly a kind of supply unit with rotatable plug.

[background technology]

Along with development of electronic technology, daily life, study and work all be unable to do without electronic product, and these electronic products usually need a supply unit to be its power supply or charging.All supply units are all similar in circuit collocation, and it is the electron exchange power circuit that is used for direct voltage is reduced or is equipped with the conversion alternating voltage, and main difference then is on the structural design that the plug of its various different sizes changes.

Please refer to Fig. 1, disclosed a kind of existing supply unit 50, supply unit 50 comprises that a housing 52 and can be assembled in the plug 54 of housing 52.Be equiped with a pair of conductive feet 540 on the plug 54 corresponding to receptacle sockets.Conductive feet 540 extends back and exposes a pair of contact jaw 544 in the trailing edge of plug 54.Have two protruding axles 542 in the both sides, rear end of plug 54, protruding axle 542 can be installed in the described housing 52.During use, plug 54 outwards overturns, and contact jaw 544 contacts (only showing a conducting strip 520 among the figure) with two conducting strips 520 in the housing 52, thereby guarantees normal conduction effect.Not the time spent, plug 54 can be contained in the housing 52 towards housing 52 upsets.Though this supply unit 50 persons of being easy to use collect or carry, yet in use, because of user's improper operation or other reason, the plug 54 of described kind of supply unit 50 very easily breaks away from housing 52, and described plug 54 still is plugged on the socket.Like this, revealing contact jaw 544 outside the plug 54 just becomes very dangerous trap, when the user touch accidentally or desire with described charger when socket is pulled up, all danger that might get an electric shock.Simultaneously, this kind supply unit 50 can not conversion direction, when supply unit 50 inserts sockets, can cause other contiguous socket of socket to use.

[summary of the invention]

For solving the deficiency that above-mentioned prior art exists, be necessary to provide a kind of supply unit with rotary connector.

A kind of supply unit comprises a pedestal and a plug.Pedestal comprises a bottom, a depression, a sidewall and at least one location division, and depression is arranged at the bottom, the side walls enclose depression, and the location division is arranged at sidewall.The location division comprises a plurality of location notchs and a plurality of flank, and location notch and flank design at interval.Plug is installed on depression rotationally, and plug comprises at least one projection, and projection is contained in the location notch and can moves between location notch.When described projection was mobile between described location notch, described plug rotated relative to described pedestal.

Because of the projection in the technique scheme can move between location notch, make that the relative position of plug and pedestal can indexing, thereby make that the relative position of supply unit and pedestal can indexing, so just some socket can not be used.

[embodiment]

Please refer to Fig. 2, disclosed the supply unit 10 of embodiment of the present invention, it comprises a pedestal 20 and a plug 30.

Please be simultaneously with reference to Fig. 4, pedestal 20 is a housing, is assembled with electronics, electric component (figure does not show) in it.Pedestal 20 comprises a bottom 22, and a circular depressed 24 is offered at 22 center in the bottom.Pedestal 20 comprises a sidewall 28 and a diapire 26, and depression 24 is surrounded by sidewall 28 and diapire 26, and diapire 26 comprises a first surface 264 and one and first surface 264 opposing second surface 266.Offer an accepting hole 260 at the center of diapire 26, described accepting hole 260 runs through first surface 264 and second surface 266.Pedestal more comprises a pair of pressing tablet 262, is arranged on the first surface 264 of described diapire 26, and pressing tablet 262 is arc and symmetric design, and radian is at least 90 degree.Pedestal 20 more comprises a pair of location division 280, is arranged on the sidewall 28, and location division 280 is arc and symmetric design, and radian is at least 90 degree.Each location division 280 comprises a plurality of location notchs 282 and a plurality of flank 284.Location notch 282 and flank 284 design at interval.Pedestal 20 more comprises a pair of stop block 286, and stop block 286 lays respectively at two ends of a location division 280, is used to prevent that plug 30 from excessively rotating.

Please be simultaneously with reference to Fig. 2 and Fig. 3, plug 30 comprises a body 32, pair of conductive sheet 34 and a pair of contact chip 36, conducting strip 34 is arranged at the centre of body 32.Conducting strip 34 can electrically connect with socket (figure does not show).Conducting strip 34 is flat, and certainly, conducting strip 34 also can be other shape, as cylindric.Body 32 is roughly circle, and it can be contained in the depression 24 of pedestal 20.Body 32 comprises a pair of projection 322 and a pair of deep-slotted chip breaker 324, and projection 322 is arranged at the circumferential edges and the symmetric design of body 32, and projection 322 can be contained in the location notch 282 of pedestal 20.Projection 322 is along the length of the body 32 thickness directions thickness greater than body 32, and outstanding from the bottom surface 320 of body 32.Projection 322 and stop block 286 cooperate can prevent that projection 322 from shifting out location division 280, thereby has protected projection 322.Groove 324 runs through described body 32 and respectively near projection 322, is used in use increasing the elasticity of projection 322.Body 32 more comprises a locating shaft 328 and a pair of resettlement section 326, and locating shaft 328 is convexly set in the bottom surface 320 of body 32 and is positioned at the center of bottom surface 320, and locating shaft 328 is a hollow, and can be contained in the accepting hole 260 of pedestal 20.Resettlement section 326 is symmetricly set in the both sides of locating shaft 328.Locating shaft 328 comprises an a pair of circular-arc barb 327 and a cross-notching 329.Fluting 329 is used to increase the elasticity of locating shaft 328.Barb 327 lays respectively at the both sides of fluting 329, and is positioned at the end of locating shaft 328.An accepting groove 325 is offered in each resettlement section 326, and conducting strip 34 passes accepting groove 325 and combines with riveted joint or welding mode with contact chip 36.Contact chip 36 can electrically connect with the pressing tablet 262 of pedestal 20.

Please refer to Fig. 2 to Fig. 5, during assembling, the locating shaft 328 of extrusion pin 30 makes locating shaft 328 be contained in the accepting hole 260 of pedestal 20, and makes barb 327 pass accepting hole 260.Simultaneously, the projection 322 of plug 30 is contained in one of them location notch 282 of pedestal 20.Like this, plug 30 just is assembled into one with pedestal 20.At this moment, two barbs 327 of plug 30 are respectively near the second surface 266 of pedestal 20.The contact chip 36 of plug 30 electrically connects with the pressing tablet of pedestal 20 262.

During use, if supply unit 10 has blocked some socket and some socket can not be used, then can operate plug 30 moves projection 322 in location division 280, make the relative position of plug 30 and pedestal 20 rotate corresponding angle, thereby the relative position of supply unit 10 and socket has also rotated corresponding angle.

Because of the existence of barb 327, so in use, plug 30 can be because of not overexerting or other fortuitous event breaks away from pedestal 20, thereby guaranteed the normal use of supply unit 10.

Because of the existence of stop block 286, in use, projection 322 can only be along the location division 280 moves, thereby has protected projection 322.
