tario, Canada, assignors to Erie Technological Products, Inc., a corporation of Pennsylvania Filed Aug. 20, 1963, Ser. No. 306,406 9 Claims. (Cl. 333-79) This invention is a combined connector and lter assembly which eliminates the increased radiation and other complications of separate lters. The filters are solidly mounted on and float with the pins to simplify inseration and withdrawal.
In the drawing, FIG. 1 is an elevation, partly broken away, of a connector; FIG. 2 is a longitudinal section through one of the lter assemblies; FIGS. 3 and 4 are longitudinal sections through modifications of the filter assemblies; and FIG. 5 is a transverse section showing the spring connection between the filter assemblies and the connector.
The connector shown in FIG. l is that typical of that used in electronic equipment andmay have from 50 to 150 more pins, each. representing a circuit.. The male connector is shown in FIG. 1. The female counterpart is of conventional design. The term pin is used to designate either a male or female connector.
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. On opposite sides of the ground plate are members 4 and 5 of insulating material having surfaces 6 and 7 making clamping engagement with the upper and lower surfaces of the ground plateiwhen Athe members 4 and 5 are bolted together. Extending from the surfaces 6`and 7 are aligned honeycomb sockets 8 and 9, each associated with a pin'10 of the connector. In the bottoms of the sockets 8, 9 are aligned clearance openings 11, 12 which provide the necessary clearance so that the pins can float to facilitate insertion and removal.` i
As shown in FIG.2,` each of the pins has a filter assembled thereon comprising a tubular ceramic capacitor 13 with inner electrodes 14 and 15 and an outer electrode 16. The inner electrode 15 is soldered at 17 to a collar 18 integral with the pin. The inner electrode 14 is soldered at 19 to a thimble 20 which is soldered to the pin at 21. Hermetically sealed within the ybore of the capacitor are a plurality of ferrite beads 22 telescoped over the pin. The connection between the outer electrode 16 and the ground plate, as shown in FIG. 5, is made through a split metallic sleeve 23 with axially extending corrugations which provides a spring connection between the outer electrode and the ground plate. The sleeve 23 conveniently can be made` of hardened shim stock.
In the assembly, the pins 10 are inserted in the recesses 8 in the member 5 which is arranged with its surface 6 presented to the upper side of the ground plate 2. The member 5 is then assembled and the parts 4 and 5 bolted together. The thrusts on insertion and removal of the pins are taken by a collar 24 on the pin and by the thimble 20. The floating of the pins permitted by the clearance between the collars 20, 24 and the bottoms of the sockets 8, 9 and by the clearance between the outer surface of the electrode 16 and the openings 25 in the ground plate facilitate insertion and withdrawal of the pins.
In FIGS. 3 and 4 are shown alternative constructions for the lter assembly. In FIG. 3, the ilter assembly is contained within a metal tube 26 soldered to a collar 27 of insulating material on the pin 28. At the opposite end, the tube is sealed by an O-ring 29. Within the tube 26 is a ceramic capacitor 30 having an outer electrode 31 Patented Sept. 27, 1966 soldered to the tube 26 by solder introduced through holes 32. The capacitor has inner electrodes 33, 34 respectively connected to the pin by sleeves 35, 36. Between the sleeves are a plurality of ferrite beads 37. The FIG. 3 assembly provides a precision surface for mounting and taking the thrusts. The outer surface of the metallic tube 26 is easily controlled to the precise dimensions desirable for electrical connection to the ground plate. The ends of the tube 26 provide the thrust surfaces for insertion and removal. The fragile ceramic capacitor is completely protected.
In FIG. 4, the pin 38 has spaced metallized ceramic collars 39, 40 soldered thereto at 41, 42. Between the collars are a plurality of ferrite beads 43. Telescoped over the collars is a ceramic capacitor 44 having an outer electrode 45 and inner electrodes 46, 47 respectively soldered to the collars 39, 40 at 48, 49. The insertion and removal thrusts are taken by the collars 39, 40.
