The present invention generally relates to a connector, and more particularly to a magnetic connector.
According to progress of electrical technology, magnetic connectors are the most widely applied connectors. Magnetic connectors have been widely applied in the various consumer products such as mobile phone, medical device, etc.

However, the conventional magnetic connector needs to differentiate the magnetic pole of the magnetic bodies 30′ in advance, and then the magnetic bodies 30′ are assembled in predetermination positions of the insulating housing according to the magnetic pole of the magnetic bodies 30′. Furthermore, before assembling the magnetic bodies 30′, the printed circuit board 20′ needs to be assembled in the insulating housing. Hence, structure and manufacturing processes of the conventional magnetic connector are complicated.
An object of the present invention is to provide a magnetic connector. The magnetic connector includes a first insulating housing, a printed circuit board, a plurality of magnetic bodies, a plurality of terminals and a second insulating housing. The first insulating housing has a bottom wall, a side wall, a recess being defined between the bottom wall and the side wall, the recess is opened at a top of the first insulating housing. The printed circuit board is received in the recess. The magnetic bodies are mounted to the printed circuit board. The terminals are mounted to the printed circuit board. The terminals are located between the magnetic bodies. The second insulating housing is mounted to the top of the first insulating housing and is covered the recess. The magnetic bodies and the terminals are exposed from a top surface of the second insulating housing. Each of the magnetic bodies is without magnetic pole before the magnetic bodies are mounted to the printed circuit board. Each of the magnetic bodies has a predetermination magnetic pole by magnetizing the magnetic bodies after the magnetic bodies are mounted to the printed circuit board.
Another object of the present invention is to provide a manufacturing method of a magnetic connector. The method of manufacturing the magnetic connector comprises steps of: providing a first insulating housing and a second insulating housing; mounting a plurality of magnetic bodies and a plurality of terminals on pads of a printed circuit board; soldering the magnetic bodies and the terminals on the printed circuit board, and the magnetic bodies being without magnetic pole at this time; magnetizing the magnetic bodies to have predetermination magnetic poles after the soldering step; assembling the printed circuit board with the magnetic bodies and the terminals into a recess of the first insulating housing; and assembling the second insulating housing to the first insulating housing to cover the recess.
Another object of the present invention is to provide a manufacturing method of a magnetic connector. The method of manufacturing the magnetic connector comprises steps of: providing a first insulating housing and a second insulating housing; mounting a plurality of magnetic bodies and a plurality of terminals on pads of a printed circuit board; soldering the magnetic bodies and the terminals on the printed circuit board, and the magnetic bodies being without magnetic pole at this time; assembling the printed circuit board with the magnetic bodies and the terminals into a recess of the first insulating housing; magnetizing the magnetic bodies to have predetermination magnetic poles; and assembling the second insulating housing to the first insulating housing to cover the recess.
As described above, the terminals and the magnetic bodies are together soldered on the printed circuit board by a surface mount technology, and then the magnetic bodies are magnetized after the soldering step. So that the magnetic pole differentiating process in the prior art is omitted, and the assembling process and the gluing process of the magnetic bodies in the prior art are further avoid. As a result, comparing with the conventional magnetic connector, the magnetic connector of the present invention has fewer manufacturing steps and simple structure. Hence, manufacture efficiency of the magnetic connector is improved, and manufacture cost of the magnetic connector is saved.
