The filtering electric connector has good effect of filtering high-frequency interference signals, and can be compatible with most of conventional electric connectors in the current market, so that the filtering electric connector is widely applied to military weaponry such as aerospace, aviation, navigation and radar, civil products such as computers, communication and various precise instruments.
The tubular ceramic capacitor is a commonly used filter capacitor element in the design and manufacture of a filter electric connector, the structure of the filter capacitor element is shown in fig. 1 and 2, the filter capacitor element comprises a bare ceramic tube 4, an inner electrode 3 arranged on the inner wall of the bare ceramic tube 4 and an outer electrode 2 arranged on the outer wall of the bare ceramic tube 4, the inner electrode 3 and the outer electrode 2 are electrically isolated through a proper insulation distance, annular solder resist strips 1 are respectively arranged on the outer wall of the bare ceramic tube 4, which are close to two ends, and preferably, the middle part of the inner electrode 3 is separated by the bare ceramic tube 4, and the two sections of inner electrodes 3 are respectively connected with a contact piece in application.
The C-type, L-type and pi-type filter circuits can be manufactured by adopting the tubular ceramic capacitor, and the corresponding electric connectors are respectively a C-type filter electric connector, an L-type filter electric connector and a pi-type filter electric connector. Taking a pi-type filtering electric connector adopting a tubular ceramic capacitor as an example, wherein the internal structure of a socket or a plug (generally a socket) of the filtering electric connector is shown in fig. 3 and 4, the socket or the plug of the filtering electric connector comprises a shell 6, a contact piece 5, the tubular ceramic capacitor 9, a magnetic bead 10, a fixed ring 8, a grounding plate 12 and epoxy resin 7, wherein the shell 6, the contact piece 5, the fixed ring 8 and the grounding plate 12 are made of metal materials, when the filtering electric connector is processed by the traditional technology, firstly, the tubular ceramic capacitor 9, the magnetic bead 10, the fixed ring 8 and the contact piece 5 are welded together to form a filtering single needle, when the filtering electric connector is welded, the fixed ring 8 with a boss structure is inserted into the tubular ceramic capacitor 9, the contact piece 5 penetrates through a central hole of the fixed ring 8 and an inner hole of the magnetic bead 10 and is welded with the fixed ring 8 and an inner electrode (see the inner electrode 3 of the tubular ceramic capacitor 9) of fig. 2, and the stacked solder 11 is formed at the welding position of the fixed ring 8, and the coaxial degree of the tubular ceramic capacitor 9 and the contact piece 5 can be realized between the tubular ceramic capacitor 3 and the inner electrode 5; then welding a plurality of filtering single pins and a grounding plate 12 together in a welding way, forming piled solder 11 at the welding part to form a filtering component, electrically connecting the external electrode 2 of the tubular ceramic capacitor 9 with the grounding plate 12 after welding, bonding the outer ring of the grounding plate 12 with a shell 6 by using conductive adhesive 13 to realize the electrical conduction between the external electrode 2 of the tubular ceramic capacitor 9 and the shell 6, finally encapsulating epoxy resin 7 inside the shell 6 to fix and protect the internal filtering component, thus, the entire electrical connector receptacle or plug is assembled.
The conventional filtering electric connector manufactured by adopting the tubular ceramic capacitor has the following defects:

The solder used in soldering contains flux, and a part of the flux remains in the cavity and cannot be removed. Residual soldering flux is easily affected by moisture and high temperature in the subsequent use process of the filter, and the insulation resistance of the residual soldering flux is gradually reduced, so that the insulation resistance of the filter electric connector is reduced, and the risk of short circuit failure possibly occurs.
