Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a fitting position schematic diagram of a male connector and a female connector; and

(2) FIG. 2 is an exploded view of the female connector.

DETAILED DESCRIPTION OF THE INVENTION

(3) In the embodiments, the fitted male and female connectors are magnetic connectors.

(4) The male connector is as shown in FIG. 1, and the conductive terminals 92 are arranged in the iron shell 96 by plastic parts 93.

(5) The female connector is as shown in FIG. 1 and FIG. 2, specifically described as follow.

(6) A plurality of conductive terminals 2 is fixed in an electrically insulated form by fixers, each fixer comprises a plastic member 3 and a composite member 4, and an assembly pin 31 of the plastic member 3 is assembled in an assembly hole 41 at the front part of the composite member 4. The head ends of the conductive terminals 2 protrude from a pin hole 30 of the plastic member 3 and expose in the terminal area of the connection surface, and the tail ends of the conductive terminals 2 protrude from the pin hole 40 in the middle of the composite member 4. The composite member 4 is formed of a magnetic conductive block coated with an insulating material layer on the surface thereof, in particular, the surface of the pin hole 30 must have excellent insulating property, and otherwise, the plurality of conductive terminals 2 will be in short circuit due to the magnetic conductive block. Hereinafter, the magnetic conductive block is called lower magnetic conductive block. Electric insulation is accomplished by fixers between the conductive terminals 2, between the magnetic conductive block and the conductive terminals 2, and between the magnet 6 and the conductive blocks 2.

(7) The magnet 6 is arranged in an inner cavity 10 surrounded by a shell 1, an upper magnetic conductive block 5 and the composite member 4. The upper and lower magnetic conductive blocks conduct the magnetic force of the magnet to the magnetic area. The upper magnetic conductive block 5 is arranged on the shell 1, with its inner surface contacting the upper surface of the magnet, and the front end face of the upper magnetic conductive block 5 is located in the magnetic area of the connection surface of the female connector; and the lower magnetic conductive block is as described above, with its surface coated with an insulating material layer. Good magnetic conduction and adsorption effects may be obtained if the front end face of the magnetic conductive block is arranged in the magnetic area of the connection surface and the magnetic conductive block contacts the magnet 6. The upper and lower sides of the female connector are large while the left and right sides are small. The magnetic conductive blocks are arranged at the large upper and lower sides, so that the magnetic conduction effect is good.

(8) The connection surface is arranged in front of the magnet 6, and the magnetic conductive blocks are arranged above and below the magnet 6. Therefore, electric elements arranged at the left, right and back sides of the magnet 6 outside the female connector are likely to suffer magnetic disturbance. In the embodiments, a magnetic shield plate 8 is arranged behind the magnet 6 in order to avoid the magnetic disturbance. Further, in order to avoid lines of magnetic force from short circuit caused by the contact between the magnetic shield plate 8 and the magnet 6, a non-magnetic conductor 7 is especially provided for partitioning the magnet 6 from the magnetic shield plate 8. The non-magnetic conductor 7 may be a layer of polyester thin film.

(9) In the embodiments, the conductive terminals 2, the plastic member 3, the front part and middle part of the composite member 4, the front end face of the shell 1, and the front end face of the upper magnetic conductive block 5 are all associated with the standard of connection surfaces, all need to be designed according to the standard of connection surfaces. But the design on the inner cavity 10, the back part of the composite member 4, the magnet 6, the back part of the shell 1, the back part of the upper magnetic conductive block 5, the non-magnetic conductor 7 and the magnetic shield plate 8 is free from the restraint on the standard of the connection surfaces.
