Description

The rotational electrical apparatus charging plug

The utility model relates to a kind of plug, particularly a kind of rotational electrical apparatus charging plug.

The rotational electrical apparatus charging plug of commonly seeing structure, as No. 82201253 patent in Taiwan " improvement of rotational electrical apparatus charging plug structure ", as shown in Figures 1 and 2, it mainly by a shell 100 with wall, reaches a headstock structure 200 and combines; Wherein, shell 100 has an embedding seat 120 that roughly is the L type, embedding seat 120 has socket 110, be formed with storage tank 130 between two sockets 110, can be in the storage tank 130 in order to put contact element 140, contact element 140 is formed with blind hole 150 with respect to storage tank 130 bottom land places, can be in order to installing spring 160 in the blind hole 150, and contact element 140 outer ends more are formed with semicircle protuberance 141.Headstock structure 200 mainly is by a lateral strut 210, two guide-joining plates 220 and inserted link 230 are formed by combining, wherein, guide-joining plate 220 is integral with inserted link 230 riveteds and can freely rotates, guide-joining plate 220 inserts the socket 110 of above-mentioned shell 100 and locatees, between two pairs of guide-joining plates 220 and inserted link 230, then plug lateral strut 210, lateral strut 210 two side ends are formed with key mouth 212, mat key mouth 212 is held clamping in addition for inserted link 230, rotate with inserted link 230, semicircle protuberance 141 opposite positions of this lateral strut 210 and contact element 140 and be formed with semicircle groove 211, with when it rotates with inserted link 230, be able to this semicircle groove 211 and semicircle protuberance 141 top contact and be rotating shaft and unlikely coming off.

The shortcoming of this structure is as follows:

1. because of guide-joining plate and the direct riveted of inserted link plug lateral strut after being integral,, cause the inconvenience in the use so positions such as semicircle protuberance 141, spring 160 and key mouth 212 can come off when inserted link is subjected to the bump of front or side.

2. the member of this structure is many, in production, part management and assembling, and the burden of very taking great energy, and the empty manufacturing cost that increases beyond doubt.

3. the jack of the necessary straight insertion socket of inserted link when using, as angular deviation is arranged slightly, inserted link will up spring back to favorite places, causes great puzzlement in the use.

4. use or the spring partly elastic fatigue and the phenomenon of getting rusty can be caused in the area indoor, that outside humidity is big because of long-term, cause original function stuck and lost efficacy.

Main purpose of the present utility model provides a kind of rotational electrical apparatus charging plug, utilize the copper runners that is made of one piece again behind copper pin and the pole riveted, add the bracing force of bonnet, difficult drop-off when making the copper pin be subjected to the bump of front or side also is difficult for making disabler because of humid environment.

Another purpose of the present utility model provides a kind of simple assembling and is easy to the rotational electrical apparatus charging plug, makes and assembly cost to reduce.

Another purpose of the present utility model provides the fixed position that syllogic is arranged when the copper pin rotates, to increase the facility on using.

The purpose of this utility model is achieved in that the rotational electrical apparatus charging plug, and it comprises at least: loam cake is to match with lower cover with ccontaining circuit board; Lower cover, be provided with an accommodation chamber in it with ccontaining copper runners, respectively there is a U-shaped embedding seat these accommodation chamber both sides with ccontaining pole, and this U-shaped embedding seat and accommodation chamber inwall form chase with ccontaining conducting strip, and accommodation chamber respectively have up and down a supporting part with the stop block of contact copper runners and a fixed part with fixing bonnet; Copper runners, its front end have two copper pin, and respectively there is a pole both sides, and an annular groove is offered on this pole top, and this copper runners is to be made of one piece behind copper pin and the pole riveted again, and there are two stop blocks and a projection in its rear end; Two conducting strips, with lead connecting circuit plate, each conducting strip front end has a semicircle open-work, via the annular groove of this semicircle open-work and pole riveted mutually; One bonnet is to insert on the accommodation chamber bonnet with contact copper runners at copper runners and conducting strip, and these bonnet both sides respectively have an open-work to pass for conducting strip, and there be the slip of a way block for copper runners projection in central authorities, a briquetting are arranged with compacting pole between open-work and way block.

The utility model has the advantages that: the rotational electrical apparatus charging plug can make the copper pin that the syllogic location is arranged, the copper pin can be done 90 ° rotation, difficult drop-off when the copper pin is subjected to the bump of front or side, convenient more in the use, and the simple assembling of its member easily, can reduce and make and assembly cost, nor easily make disabler because of humid environment.
