Ceramic feed-through filter integrated block, filtering electric connector and preparation method thereof

Abstract

The invention discloses a ceramic feed-through filter integrated block which comprises a substrate, a plurality of ceramic tubular capacitors and contact pins corresponding to the ceramic tubular capacitors in number. The ceramic tubular capacitors are arranged on the substrate, one contact pin is arranged in each ceramic tubular capacitor, and the contact pins penetrate through the ceramic tubular capacitors to be in welded connection with the ceramic tubular capacitors and serve as inner-end electrodes of the ceramic tubular capacitors. The invention also discloses a filtering electric connector including the ceramic feed-through filter integrated block and a preparation method of the filtering electric connector. The filtering electric connector is uniform in parameter distribution, compact in structure, strong in anti-conducted-interference capability and capable of achieving multi-frequency or mixed filtration. In addition, by adopting the preparation method, difficult real-time monitoring of a traditional filtering electric connector and the shortcoming that the construction operation in a process section is performed in a quality out-of-control state can be fundamentally avoided and get rid by adopting the preparation method, and the pass percent of product quality is obviously improved.

Description

technical field [0001] The invention relates to the technical field of electric connectors, in particular to a ceramic through-core filter integrated block, a filter electric connector and a preparation method of the filter electric connector. Background technique [0002] For a long time, the international and domestic industries that produce filter electrical connection devices have different production methods and uneven technological levels, but so far there is still one thing in common: after the qualified separation components are ready, once they enter the welding process It cannot be stopped, because all the separation components such as structural parts and filter electronic parts are combined and mixed when they are installed in the connector housing. Sealing and curing can only be done in a one-time continuous operation, and timely measurement and control of quality indicators and filter electrical performance indicators cannot be carried out during the process.

Problems solved by technology

Moreover, it is not possible to provide a feasible quality analysis mode and quality solution for the production of the same model in future batches

Strictly speaking, for the quality problems that arise, if they cannot be analyzed and qualitative, they cannot be zeroed, and they cannot be finalized and put into use

At the same time, most of the existing filter electrical connectors are single-purpose electrical connectors, which are suitable for a single product. When connecting different components, appropriate electrical connectors need to be used, which has poor versatility.
