1. Field of the Invention
The present invention relates to a magnetic connector assembly.
2. Description of Related Arts
U.S. Pat. No. 7,632,134, issued on Dec. 15, 2009, discloses a magnetic connector including a mating section, a magnetic element having a cavity, and a plurality of retractable, POGO-type contacts accommodated in the mating section and the cavity. The magnetic connector further includes a terminal block receiving the contacts, an internal printed circuit board, and a protective member.
U.S. Patent Application Publication No. 2013/0210244, published on Aug. 15, 2013, discloses a magnetically-conductive label and a magnetic connector system including portions of connector insert (plug) and connector receptacle. Connector receptacle may include one or more magnets, which may be covered by label. Connector insert may include an attraction plate. Magnetic field lines originating in first magnet may pass through label and attraction plate and terminate in second magnet. Specifically, magnetic field lines originating in a North pole of a magnet terminate at a South pole of another magnet. Magnets may be formed of various materials and may be arranged in various configurations. For example, a single magnet may be employed where a first magnetic element may extend from a North side of the magnet to an opening and a second magnetic element may extend from a South side of the magnet to the opening U.S. Pat. No. 7,311,526, issued on Dec. 25, 2007, discloses an electrical plug and receptacle relying on magnetic force to maintain coupling. Each of the plug and the receptacle comprises a magnetic element and a plurality of contacts accommodated in the magnetic member. Also disclosed are complementary guides that allow for only one way of coupling the plug and receptacle together to ensure proper alignment of the plug contacts with the receptacle contacts. An electrical connector assembly having guiding means is desired.
To achieve the above object, an electrical connector assembly comprises: a first connector comprising a first magnetic element having a cavity, and a plurality of first contacts accommodated in the cavity of the first magnetic element; and a second connector comprising a second magnetic element and a plurality of second contacts accommodated in the second magnetic element; wherein the first magnetic element and the second magnetic element include a pair of opposite poles located at two ends thereof respectively along a direction perpendicular to a mating direction of the first magnetic element and the second magnetic element; and wherein when the first connector mates with the second connector, the poles of the corresponding ends of the first magnetic and the second magnetic element are opposite.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Reference will now be made in detail to the preferred embodiment of the present invention.

The first contacts 113 comprise a first power contact 113a, a first grounding contact 113c and a first signal contact 113b located between the first power contact 113a and the first grounding contact 113c. Each first contact 113 comprises a mating portion 1131 mating with the second connector 200 electrically, a holding portion 1132 extending rearwardly from the mating portion 1131 and fixing the first contact 113, and a connecting portion 1133 extending rearwardly from the holding portion 1132 and connected with the printed circuit board 115. The holding portion 1132 is thicker than the mating portion 1131 and the connecting portion 1133.
The first spacer 114 is made of plastic material, and comprises a main portion 1141 and a rear portion 1142 extending rearwardly from the main portion 1141. The rear portion 1142 is wider than the main portion 1141. The first spacer 114 defines a plurality of grooves 1140 extending through the main portion 1141 and the rear portion 1142 and receiving the first contacts 113. The mating portions 1131 of the first contacts 113 reach out of the grooves 1140.
The first magnetic element 112 surrounds the main portion 1141 and defines a receiving chamber 1121 extending through a front surface and a rear surface thereof The first metal shell 110 surrounds the first magnetic element 112 and defines a receiving space 1101 receiving the first magnetic element 112 and the first spacer 114. The periphery of the first metal shell 110 is corresponding to the port 2201 of the panel 220, so that the first metal shell 110 can enter into the port 2201 of the panel 220.
In assembly, the first contact 113 is assembled to the first spacer 114. The first magnetic element 112 is assembled to the main portion 1141 of the first spacer 114. The first contact 113 and the cable 130 are assembled to the printed circuit board 115 electrically. The first metal shell 110 is assembled to the first magnetic element 112 and the first spacer 114. The cover 120 is assembled to the rear end of the first metal shell 110 and the front end of the cable 130.
