SELF-ALIGNING ELECTRICAL CONNECTOR STRUCTURE Filed oct. 8. 195s United States Patent O SELF-ALIGNING ELECTRICAL CONNECTOR STRUCTURE Sion Colvin, Chicago, Ill., assignor to Western Electric Company, Incorporated, New York, N.Y., a corporatron of New York Application October 8, 1953, Serial No. 384,852
2 Claims. (Cl. 339-59) lThe present invention relates to a self-aligning electrrcal connector structure, and more particularly to a device for supporting an electrical connector element for oating movement for making connections to an electronic tube of the magnetron type.
Electronic tubes of the magnetron type have a cathode disposed in an accurately predetermined position relative to an anode and mounted on one end of a stem, the other end of which is supported on a terminal component of the magnetron to which electrical connections are made for applying potentials to the cathode. After fabrication of the tube and during the testing thereof the tube is clamped in a holding fixture and the cathode supporting component of the magnetron is engaged by a connector electrically connected to the testing apparatus for applying predetermined potentials to the cathode. During the testing of the magnetron and the application of relatively high potentials thereto the cathode supporting component of the magnetron is heated and may be distorted by the application of external force thereto and thereby cause the misalignment of the cathode. Hence, it is essential to provide a ilexible floating structure for making electrical connections which will not impart any stresses to the cathode supporting component to cause distortion and alter the alignment of the cathode.
It is an object of the present invention to provide a iloating, self-aligning mounting for electrical connectors.
It is a further object of the invention to provide an electrical connector structure having the contactors supported against movement axially thereof while permitting free movement laterally thereof and limited tilting movement to permit the self-alignment of the electrical contactors with cooperable connector elements on electrical devices being connected thereto.
One type of apparatus illustrating certain features of the invention as applied to a connector for establishing an electrical connection between a test set and an electrical device to be tested, may include a lconnector element centrally mounted on a mounting sheet of insulating material which is slightly flexible and is disposed in an aperture of a frame plate of slightly greater thickness than the sheet and in engagement with curved leaf springs interposed between the outer edges of the sheet and the inner walls of the frame plate and supported thereby for free iloating movement parallel to face of the sheet. A pair of apertured retaining plates are secured on opposite sides of the frame plate in overlapping relation to the marginal edges of the supporting sheet for holding the sheet and the electrical connector thereon against movement transversely of the sheet while permitting free lateral and a limited rotative movement of the connector element,
whereby the connector element may readily align itself with a contact member of an electrical device to be tested and establish electrical connections between the device and a testing apparatus.
Other objects and advantages of the invention will become apparent by reference to the following detailed de- 2,882,510 Patented Apr. 14, 1959 ICC scription and the accompanying drawings illustrating a preferred embodiment thereof, in which Fig. 1 is a diagrammatic side elevational view of a testing apparatus for testing electronic tubes showing the self-aligning electrical connector mounting;
Fig. 2 is an enlarged face view of the mounting taken on the line 2--2 of Fig. 1 with parts broken away;
Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2; and
Fig. .4 is a horizontal sectional view taken on the line 4-4 of Fig. 2.
The present connector structure 10 is designed to support an electrical connector element 12 for floating movement to enable the electrical connector to align itself and engage the terminal component 14 of a magnetron electronic tube 16 during the testing of the magnetron. The magnetron has a cathode 17 coaxially aligned within a hollow anode 18 and mounted on one end of a stem 19, which at its other end is bonded to the terminal component 14. During the testing thereof the magnetron 16 is clamped in fixed position between a pair of jaws 22 of a holding fixture 23 mounted on a base 24.
The electrical connector element 12 comprises a pair of contact elements 26 and 27 mounted centrally on a sheet 28 ofrelatively stiff insulating material capable of being ilexed to permit the connector element 12 to be tilted slightly. The sheet 28, which serves as a heat and electrical insulator and may be of various configurations, is shown herein as having a rectangular outline. The contact element 26 is tubular in form and has a ange 29 which is secured to the sheet 28 of insulating material by a plurality of rivets or screws 30 and the contact element 27 is in the form of a pin mounted coaxially within the member 26 and secured to sheet 28 of insulating material by a screw 31. The sheet 28 is disposed in a rectangular opening 33 of a frame member 34 of insulating material having a thickness slightly greater than that of the sheet 28. The opening 33 in the frame member 34 is larger than the sheet 28 and of the same general configuration and provides spaces 35 between the outer edges of the sheet 28 and the inner edges of the member 34. The sheet 28 is yieldably supported on a plurality of at leaf springs 36, the ends of which slidably fit into slots 37 in the frame member 34. The springs 36 are curved and are held in slots in a manner to cause the middle portion thereof to engage and support the sheet 28 for floating movement in any direction parallel to the face of the sheet 28. Plates 38 and 39 of insulating material having central apertures 40 and 41, respectively, are secured to opposite sides of the frame member 34 by rivets or bolts 42 and overlie the spaces 35 and the marginal shoulder portions of the sheet 28 to prevent movement of the sheet in a direction transversely of the face thereof while permitting free [oating movement of the sheet 28 and the connector 12 parallel to the face of the sheet.
An angle bracket 45 fixed to the base 24 supports the connector structure 10 in a predetermined stationary position relative to the holding xture 23 and with the connector 12 in substantial alignment with the axis of a magnetron tube supported in the holding xture. Thus, when a magnetron tube is being clamped in theholding fixture 23 and the terminal component 14 is brought into engagement with the connector element 12, this connector element 12 moves freely and aligns itself with the terminal component 14 of the magnetron without imparting any stresses thereto which might effect the misalignment of the cathode.
The contact elements 26 and 27 are electrically connected by leads 46 and 47, respectively, to a test set 50 for applying the proper potentials thereto during the testing of the magnetron.
It is to be understood that the above-described arrange- 3 ne'n'ts are simply illustrative ofthe application of the principles of this invention'. Numerous other arrangements may be readily devised by those skilled in the art which will embody the principles of the invention and fall withinv thel spirit and scope' thereof;
