tario, Canada, assignors to Erie Technological Products,
Inc., a corporation of Pennsylvania Filed Aug. 20, 1963, Ser. No. 306,407 4 Claims. (Cl. 333-79) This invention is a feed through inductance, capacitance filter for high frequency circuits which is particularly advantageous in connectors where floating of the connector pins is required to simplify insertion and withdrawal. Each pin and its associated filter comprises a unitary assembly with the filter elements housed within a metal tube to which ground connections may be made.
In the drawing, FIG. 1 is an elevation, partly in section, of a connector; FIG. 2 is a section through one of the filter assemblies; FIG. 3 is a section through `a modification of the filter assembly, and FIG. 4 is yan elevation of another modification.
The connector shown in FIG. l is typical of that used in the electronic equipment and may have from 50 to 150 or more pins, each representing a circuit. The m-ale connector is shown in FIG. l. The female counterpart is of conventional design.
The connector has a metallic housing 1 having at its center a ground plate 2 connected to the inside of the housing by a spring connector 3 which provides electrical connection and permits relative movement between the ground plate and the housing. On opposi-te sides of the ground plate are upper and lower members 5 and 6 of insulating material having surfaces 7, 8 which respectively abut the upper and lower sides of the ground plate when the members are suitably clamped together, for example, by through bolts (not shown). A plurality of yaligned honeycomb sockets 9, 10 Vrespectively extend inward from the surfaces 7, 8 and in the bottom of each socket is an opening 11, 11a of slightly larger diameter than the associated pin 12. There are `as many openings 11, 11a as there are pins. The clearance between the pins and the openings permits floating of the pins desirable for insertion and removal.
The filter assembly for each pin is shown in FIG. 2. It comprises a large ceramic capacitor 14, one or more ferrite beads 15, and a small ceramic capacitor 16 telescoped over the pin 12 in the order named. The large capacitor 14 butts `against a flange 17 on the pin .and its inner electrode 18 is soldered to the flange Iat 19. A metal tube 20 is telescoped over the capacitors and the ferrite beads and the `outer electrode 21 of the large capacitor is soldered to one end of the tube `at 22. The opposite end of the metal tube 20 is soldered at 23 to the outer electrode 24 of Ithe capacitor 16 and the inner electrode 25 of the capacitor 16 is soldered at 26 to the pin 12.
The metal tube can be made to close tolerance both as to diameter and as to length. While the ceramic capacitors cannot be made to as close tolerances, any clearance between the capacitors and either the pin 12 or the inside diameter of the tube 20 is bridged iby the soldered connections 19, 22, 23, 26 so that the capacitors are located in fixed relation to the pin. The filter is protected from injury. The metal tube 2) encloses Ithe full length of the ceramic. At one end, the shoulder 17 takes the thrusts. At the other end the projecting end 27 of the tube takes the thrusts.
In assembly, the filter element is assembled on each of the pins. The assembled pins are then dropped into the sockets 9 and the member 5 arranged on one side of the ground plate 2. In this position, annular spring members 28 make connection between the ground plate yand each "ice of the tubes 20. The member 6 is then assembled on the opposite side of the ground plate. When the members are bolted together, each of the pin and filter assemblies is loosely carried in the aligned sockets 9, 10 with the tubes 20 grounded by the connectors 28 and with shoulders 17 and 27 in position to cooperate with shoulders 29 and 30 to accommodate the axial thrusts.
In the modification shown in FIG. 3, the pin 31 (corresponding to pin 12) has 'a collar 32 which is soldered at 33 to an inner electrode 34 on a tubular capacitor 35. A metal tube 36 is telescoped over the capacitor 35 `and the outer capacitor electrode 37 is soldered to the tube at 38. A plurality of ferrite beads 39 are arranged between the capacitor 35 and another tubular capacitor 40 having an outer electrode 41 soldered to the metal tube at 42 and having an inner electrode 43 connected to the pin by a collar 44 soldered to both the pin 'and to the inner electrode. In this assembly, the metal tube 36 protects the ceramic capacitors 4and also supplies a precision metallic surface to which contact may be easily made. The filter assembly of FIG. 3 is adapted to higher voltages because the flanges 45 and 46 on the outer ends `of capacitors 35 `and 40 provide a longer insulating band. In the construction of FIGS. 1 and 2, the insulating b-and between the capacitor electrodes is limited by the thickness of the capacitor dielectric.
In the construction of FIG. 4, the metal tube 47 is provided with a mounting flange 48. The internal construction may be the same as in the previously described filters.
