Abstract
The present invention relates to a D-subconnector provided with ferrite cores, formed in the opposite ends of a computer signal cable which connects to a computer body and a monitor. More particularly the plurality of ferrite cores are incorporated in an interior of the D-subconnector, and a copper plate is inserted between the cores. This configuration substantially attenuating magnetizing action. Additionally, the copper plate can achieve common grounding inside the D-subconnector. Moreover, the present invention can obtain an E.M.I. effect while obtaining clearer images and reducing the occurrence of a short-circuit.
Claims6
A D-subconnector comprising:
- a plurality of ferrite cores having at least three sets of pin holes, at least one set of the pin holes comprising two connected pin holes;
- a fixed plate having a plurality of pin holes configured to receive a plurality of connecting pins;
- and
- a plurality of metal shells that hold said plurality of ferrite cores and an insulator,
- wherein said plurality of ferrite cores are provided in an interior of the D-subconnector, a copper plate having a plurality of pin holes is provided between said ferrite cores, and said copper plate having a bent ground part on one side that is grounded to at least one of said metal shells.
A cable with a D-subconnector comprising:
- a plurality of ferrite cores having at least three sets of pin holes, at least one set of the pin holes having two connected pin holes;
- a fixed plate having a plurality of pin holes configured to receive a plurality of connecting pins;
- and
- a plurality of metal shells that hold said plurality of ferrite cores, a copper plate, and an insulator,
- wherein diameters of pin holes formed in said copper plate are at least one of a first size and second size, said first size pin holes contacting the connecting pins and the second size pin holes not contacting the connecting pins.
