BACKGROUND

1. Technical Field

The present disclosure relates to electronic components, particularly to a connector with a shielding device and a method for manufacturing the connector.

2. Description of Related Art

Connectors are used to connect a first component to a second component. Generally, the connector includes a contact, a terminal, an interface, and other conductors. However electromagnetic interference and electrostatic discharge often exist between the terminal and the interface of the connector. Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION

FIG. 1illustrates a connecter in accordance with an embodiment. The connector comprises a main body10and a shielding device30attached to the main body10. The shielding device30is used to prevent the main body10from electromagnetic interference and electrostatic discharge.

The main body10includes a circuit board11and a plurality of cables13connected to the circuit board11. A plurality of electronic components112(only two shown inFIG. 1) are attached to the circuit board11. Each of the plurality of cables13comprises a plastic jacket131, a plurality of center cores133, and a plurality of dielectric insulators132enclosing the plurality of center cores133. The plurality of dielectric insulators132are received in the plastic jacket131, and the plurality of center cores133are attached to the circuit board11. In one embodiment, the plurality of center cores133are secured to the circuit board11by soldering.

The shielding device30comprises a first insulating member31, a copper foil32, and a second insulating member33. The first insulating member31is secured to the circuit board11and covers the circuit board11. In one embodiment, the first insulating member31is polyethylene and is secured to the circuit board11by injection molding. The copper coil32is secured to the dielectric insulators132and located between the first insulating member31and the second insulating member33. In one embodiment, the copper coil32is secured to the dielectric insulators132by soldering. The second insulating member33encloses the copper coil32to insulate the circuit board11. In one embodiment, after the first insulating member31and the circuit board11are secured together, the second insulating member33is secured to the first insulating member31by injection molding. The second insulating member33is thermoplastic rubber. In one embodiment, a cross-section of the first insulating member31is substantially a rectangle, and the second insulating member33is substantially a rectangle.

FIGS. 2-3illustrate an assembled view of the connecter in accordance with an embodiment. In assembly, the plurality of center cores133is secured to the circuit board11. The circuit board11with the plurality of center cores133is placed in a first mold (not shown), and a polyethylene material is fed into the first mold to form the first insulating member31. Thus, the first insulating member31can cover the circuit board11. The copper foil32encloses the first insulating member31and secured to the plurality of dielectric insulators132by soldering. The main body10with the first insulating member31and the copper foil32is placed in a second mold (not shown), and a thermoplastic rubber material is fed into the second mold to form the second insulating member33.

In use, the circuit board11is covered by the copper foil32, so that the circuit board11can be protected from disturbing by false signals from the outside of the circuit board or the inside of the circuit board11. The copper foil32is connected to the plurality of dielectric insulators132, so that the copper foil32can be for ground. Therefore, the false signal from the outside of the circuit board or the inside of the circuit board11can be transferred to the ground.

In addition, the first insulating member31and the second insulating member33are made by injection molding. The main body10is protected by the first insulating member31and the second insulating member33, so that each of the plurality of electronic components112, the solder joint between each of the plurality of center cores133, and the circuit board11and the solder joint between the copper foil32and the plurality of dielectric insulators can be protected well. The first insulating member31is substantially a rectangle, and the copper foil32can be easily covered on the first insulating member31.
