Problems solved by technology

At present, the existing filter electrical connectors have the following problems: single frequency integration, high and low frequency mixing integration cannot be realized; ceramics, contacts, shells, solders can only be involved in the production process at the same time in a small space, and there are too many uncontrollable factors. The quality is not guaranteed; the place where the inductor is installed between the ceramic interposers cannot be potted, and it is easy to be affected by moisture, has low corrosion resistance, and poor anti-vibration effect when used in the machine; and the filter electrical connector made by the existing production process, the product The scrap rate is high, and scrapped products cannot be repaired, so the pass rate of the product is low and the production cost is high

Embodiment 1

[0043] The preparation method of the TCC group mode filter electrical connector comprises the following steps:

[0044] a. Prepare the monolithic ceramic tube, metal contact body and shell required for production, and test the electrical performance index of the monolithic ceramic tube, the size of the metal contact body and the surface coating (check whether the coating is the corresponding required thickness, and The coating is a precious metal), which is tested by physical and chemical methods;

[0045] b. passing a metal contact body through a monolithic ceramic tube and connecting the outer surface of the metal contact body with the inner surface of the monolithic ceramic tube by welding to obtain an independent discrete assembly;

[0046] c. Check the welding index and filter electrical performance index of the discrete assembly obtained in b, inspect the TCC pipe body and the through-metal contact body for virtual welding and missing welding with a visual instrument, an...

Embodiment 2

[0057] Both the grounding plate and the shell are Y-shaped, and the grounding plate corresponds to the model of the shell. The metal contact body is selected from high-frequency discrete assemblies; the solidified layer of the encapsulation material and the air contact surface are provided with a plastic insulating plate, which prevents leakage and assists the electrical connector to better realize the filtering function. The surface of the plastic insulating sleeve at the cable outlet end of the metal contact body is provided with a pattern identification sheet, which is convenient for distinguishing the corresponding functions of each discrete assembly and the connection with the corresponding cable. The center-to-center distance between the metal contacts is greater than or equal to 0.635. Under the condition of center spacing ≥ 2.54㎜, AC and DC mixed integration can be realized; under the condition of center spacing < 1.27㎜, C-type filter circuit can be used; under the con...

Embodiment 3

[0059] Both the grounding plate and the shell are Y-shaped, and the grounding plate corresponds to the model of the shell. The metal contact body is selected from the combination of the low-frequency discrete assembly and the high-frequency discrete assembly; the solidified layer of the encapsulation material and the air contact surface are provided with a plastic insulating plate, which prevents leakage and assists electrical connection The device can better realize the filtering function. The surface of the plastic insulating sleeve at the cable lead-out end of the metal contact body is provided with a pattern identification sheet, which is convenient for distinguishing the corresponding functions of each discrete assembly and the connection with the corresponding cable. The center-to-center distance between the metal contacts is greater than or equal to 0.635. Under the condition of center distance ≥ 2.54㎜, AC and DC mixed integration can be realized; under the condition o...

Abstract

The invention discloses a preparation method of a TCC group mode filtering electric connector. The preparation method comprises the following steps: preparing manufacturing materials including a monolithic ceramic tube, a metal contact body and a shell; the metal contact body penetrating through the monolithic ceramic tube to be welded to obtain a discrete assembly, welding and integrating the discrete assembly to obtain a filtering module, and packaging and curing the two ends of the filtering module to obtain a packaging module; welding the packaging module with the shell or adhering and shielding the packaging module with a conductive adhesive to obtain a filtering electric connector welding or conductive adhesive adhering assembly; packaging and curing the two ends of the filtering electric connector welding or conductive adhesive bonding assembly to obtain a filtering electric connector packaging and curing assembly; and assembling the filtering electric connector packaging and curing assembly to obtain a TCC group mode filtering electric connector, and detecting, qualification and warehousing the TCC group mode filtering electric connector. The process is smooth, the operation is performed in an open state before total assembly, only the packaging module is associated with the shell during assembly, and the finished product percent of pass is high; the quality in the production process is controlled and can be cyclically maintained without influencing the normal line production; the production efficiency is high and the product quality is good.
