Description

A kind of suction type charging inlet

Technical field

The utility model relates to the electronic product of employing rechargeable battery and the charging inlet between charger, refers more particularly to a kind of suction type charging inlet.

Background technology

Due to the classification of waterproof of LED watertight light fitting product for guaranteeing to require, all adopt all-sealed design in design, built-in chargeable lithium cell.At present, usually whole light fixture is placed on the charger of traditional employing charging charging inlet its built-in lithium battery is charged, that is: with the support platform of charger as whole light fixture, by the light fixture self gravitation with the charging thimble close contact that is filled contact and charger on light fixture.But for the larger large-scale light fixture of volume, because the base of the charger of traditional charging charging inlet is too little, large-scale light fixture is very easy to topple over; And because the contact of being filled on large-scale light fixture is not easy to aim at the position of the charging thimble of charger, it is very inconvenient to use.

The utility model content

Technical problem to be solved in the utility model is: provide a kind of the needs that the self gravitation of light fixture is held out against the active force that is filled the contact on light fixture and contraposition suction type charging inlet very easily as the charging thimble of charger.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the suction type charging inlet, comprise: charging housing and filled housing, filled to be provided with on the base plate of housing and be subjected to electric cavity, be provided with the charging protuberance that can rotate on the base plate of charging housing in being subjected to electric cavity, be equipped with a center thimble that is positioned at the center, one on charging protuberance end face and be positioned at the eccentric thimble that departs from its center, be provided with the central contact that matches with the center thimble and the annular contact of matching with eccentric thimble on the described diapire that is subjected to electric cavity; Be provided with the first magnet of at least one pair of circumferential arrangement on the inner surface of described charging housing base plate, be provided with on the described inner surface that is filled the housing base plate with the quantity of the first magnet equate, position corresponding and opposite polarity the second magnet one by one.

The concrete set-up mode of described the first magnet and the second magnet is: the charging housing and filled housing separately on the inner surface of base plate along circumferentially evenly being provided with respectively and the first magnet or the second magnet placing chamber one to one, the first magnet correspondence one by one is placed in the placing chamber of charging housing, and the second magnet is corresponding being placed in the placing chamber that is filled housing one by one.

Described center thimble and eccentric thimble are spring thimble.

the beneficial effects of the utility model are: the charging protuberance of the charging housing in the utility model can rotate in being subjected to electric cavity, and, regardless of the protuberance that charges in the position that is subjected to electric cavity, the center thimble contacts with central contact all the time, eccentric thimble contacts with annular contact all the time, so just need not deliberately go contraposition, greatly facilitate use, in addition, owing to being provided with the first magnet of at least one pair of circumferential arrangement in the charging housing, being filled the quantity that is provided with in housing with the first magnet equates, the position is corresponding and opposite polarity the second magnet one by one, making the charging housing and being filled the housing adhesive gets very firm, the charging thimble that can guarantee charger holds out against being filled on the contact on light fixture, thereby do not need the self gravitation of light fixture is held out against the active force that is filled the contact on light fixture as the charging thimble of charger, also just abandoned traditional charge mode that light fixture is placed on charger, greatly widened the scope of application of the present utility model.
