Filtering electric connector contact

Abstract

The invention discloses a filtering electric connector contact. The contact is used for power supply signal transmission in a filtering electric connector; a magnetic tube, a capacitor tube, a copper coil and a metal tube are sleeved outside a contact insertion pin or a contact insertion hole of the contact in sequence; the capacitor tube and the contact insertion pin or the contact insertion hole are connected by welding the end parts; and the copper coil and the metal tube are connected by welding the end parts. According to the contact, by sleeving the magnetic tube and the capacitor tube on the contact insertion pin or the contact insertion hole directly, the contact has both functions of signal connection and filtering; the contact is separately fixed with a low level signal contact in the connector, so that the interference is avoided, and thus the contact has the characteristics of being simple in structure, simple and convenient to assemble and high in reliability and has wide popularization and application value.

Description

technical field [0001] The invention relates to a filter electrical connector contact piece, which belongs to the technical field of electrical connectors. Background technique [0002] A filter electrical connector is an electrical connector that has a filter installed inside it, such as a capacitor and a magnetic ring, and has a certain ability to resist electromagnetic interference. [0003] With the development of electronic equipment toward integration and diversification, new requirements are put forward for filter electrical connectors. More and more electronic equipment requires that not only low-level signals but also power signals be transmitted in the same connector. , but the contacts that transmit various signals must be connected to the same capacitor plate. Due to the relatively large size of the contacts that transmit the power signal, and the relatively large size of the filter, it seriously affects the miniaturization of the equipment, and the power signal ...

Problems solved by technology

[0003] With the development of electronic equipment toward integration and diversification, new requirements are put forward for filter electrical connectors. More and more electronic equipment requires that not only low-level signals but also power signals be transmitted in the same connector. , but the contacts that transmit various signals must be connected to the same capacitor plate. Due to the relatively large size of the contacts that transmit the power signal, and the relatively large size of the filter, it seriously affects the miniaturization of the equipment, and the power signal transmission is all large. The power signal generates a large electric field and magnetic field near the contact, which interferes with the low-level signal, so that the electromagnetic compatibility of the same connector cannot meet the requirements due to the integration of the low-level signal contact and the power signal contact.
