Filter connector

Abstract

The invention relates to a filter connector which comprises a square insulator; a square blind hole is arranged at the rear section of the insulator; a through hole for a contact to go out through is externally arranged on the bottom surface of the blind hole of the insulator; the contact with the front section being arranged in the through hole is arranged in the through hole; the rear end of the contact extends out of the rear end surface of the insulator; an earth plate is arranged in the blind hole of the insulator; a setting hole for the contact to pass through is arranged on the earth plate; a tubular capacitor which passes through the contact in a limit way is arranged between the setting hole and the contact; the inner side surface of the tubular capacitor is electrically connected with the contact in a contact way; a conductive spring hole on the outer side surface of the tubular capacitor which is limited and sleeved on the periphery of the tubular capacitor is electrically connected with the wall of the setting hole; a glue-poured seal piece which fixes the contact and the earth plate in the insulator is arranged in the blind hole of the insulator; and at least one end of the earth plate is provided with an earth terminal which extends out of the rear end surface of the insulator.

Description

technical field [0001] The invention relates to a connector for transmitting electric signals with filter function. Background technique [0002] Filter connectors are widely used because they can filter out harmful clutter and realize electromagnetic shielding so that the signals transmitted on the contacts are not disturbed by the outside world. There are many forms of filter connectors. There is a filter connector, such as Figure 1~3 As shown, the connector is a square connector, including a square housing 5, a square inner hole is arranged in the housing 5, an insulator 4 is installed at the front end of the inner hole of the housing 5, and a There are two assembling edges which are press-fitted with the insulator 4 to prevent the insulator 4 from protruding from the front end of the housing 5, and are respectively arranged at two ends of the housing. In the inner hole of the housing behind the insulator 4, an insulating rubber pad 3 formed by poured glue is arranged, a...
