| 61 | Sliding contact and method for producing the same | US10486099 | 2004-02-09 | US20040205965A1 | 2004-10-21 | Mitsuyoshi Sayama; Kenitiro Tani; Hirohito Suzuki |
| The object is to provide a method of manufacturing a sliding contact which has a high yield of manufacturing sliding contacts and can positively make smooth the tip portion surface of a finger of a brush of a sliding contact. According to the invention, in a method of manufacturing a sliding contact having a metal brush, the tip portion of a finger 12anull of a sliding contact piece 10null is melted and thereafter the tip portion is solidified in a gas, whereby the surface of the tip portion is made smooth. For example, when a sliding contact is manufactured by blanking a metal sheet material, the tip portion of the finger 12anull of the brush 12null of the sliding contact piece 10null which is obtained by blanking is irradiated with a laser beam, whereby the tip portion is heated and melted. Then, a sharp portion and a burr which exist before melting disappear. When the tip portion of the finger 12anull is solidified in a gas after melting, a sliding contact having a brush provided with a finger whose tip portion surface is a smooth curved surface is manufactured. | ||||||

| 64 | Armature assembly for balanced moving armature magnetic transducer and method of locating and adjusting same | US09779920 | 2001-02-08 | US20020125972A1 | 2002-09-12 | George C. Tibbetts; Joseph A. Sawyer |
| In a folded armature assembly the vibratory end portion of the armature is prelocatable both translationally and rotationally relative to the facing pole surfaces of the permanent magnetic flux means before attachment of the supported portion of the armature to said means. The armature has wings extending laterally from the supported portion to form therewith a connecting bridge portion, and the wings are formed to provide pads extending normal to the bridge. A magnet strap with attached magnets fits slidably between the pads, with a clearance from the bridge of the armature, to permit said locations before the parts are permanently attached. After attachment and with the magnets magnetized, the armature may be adjusted substantially in translation to magnetic center between the pole faces by appropriate plastic deformation of the bridge. In a preferred embodiment, an improved structure is provided for viscoelastic damping of the undesirable second natural resonant mode of the folded armature. | ||||||
| 65 | Switching contact for electrical switching devices | US09968303 | 2001-10-01 | US20020079205A1 | 2002-06-27 | Karl-Heinz Gunzelmann; Manfred Knofel; Wolfgang Schlenk |
| The switching contact is suitable for electrical switching devices. A contact element is connected to a contact support. In order to connect relatively large contact elements to the contact support with sufficient connection quality, in particular by means of cost-effective resistance welding or laser welding, the contact element is formed from a number of contact element segments and the individual contact element segments are assembled to make up the contact element. Different switching properties can be set by using contact element segments of the same or different material compositions and/or geometries. | ||||||
| 66 | Float sensor employing reed switch | US09419275 | 1999-10-15 | US06380499B1 | 2002-04-30 | Paul K. Edwards |
| A reed switch in a solid plastic body is positioned by a clip adjacent to a fluid container. A change in fluid level opposite the reed switch moves a magnet connected to a float, turning the reed switch on or off. Glass filled polyester is injected into a die which surrounds the reed switch supported on electrical plug blades. The reed switch has high stiffness leads positioned on the blades, and is oriented within the mold so the injected plastic flows along the glass tube of the reed switch, minimizing stresses on the reed switch, which could result in the reed switch becoming crack and/or broken. The molded plastic body incorporates an integrally formed clip arm that functions to position and hold the plastic body onto a larger structure. The magnet and float may move in a tube, may pivot, or slide along rails in response to a change in fluid level. | ||||||

| 70 | Method of making a polarized electromagnetic relay | US52697 | 1998-03-31 | US5940955A | 1999-08-24 | Daniel Robert Smith |
| A polarized electromagnetic relay includes a base, an electromagnet with a coil and a pair of pole pieces extending perpendicularly from the end of said coil, a balanced armature and spring system which when actuated pivots between two fixed contact points and a permanent magnet inducing the same magnetic poles in both of said pole pieces and providing an opposite pole in closely adjacent relationship to the central portion of the armature. A movable contact spring is fixedly connected to the armature, said spring forming contact arms at either armature end portion. Further, a flexible movable braid connects the movable contacts on said movable spring to each other and to a movable contact terminal. A pair of retaining tabs extending from a central bobbin flange engaging corresponding recesses at the lateral sides of the armature limits the movement of the armature in two directions as well as its rotation. This feature eliminates the need for a torsion spring and allows the contact forces to be higher if necessary. Two identical coils wound in a common direction are provided as the means for actuation. Armature transfer will occur by either applying a voltage pulse across the appropriate coil, or by toggling the voltage pulse polarity across the two coils connected in series. | ||||||
| 71 | Sliding contact producing method | US55948 | 1993-04-28 | US5416969A | 1995-05-23 | Akito Miura |
| A sliding contact producing method is provided wherein noble metal balls are easily positioned on a metal plate; the weld strength between the noble metal ball and the metal plate can be obtained sufficiently; and a noble metal mounting jig can be prevented from damage when the metal plate is beam-welded with the noble metal ball. While being received in the recess portions of a jig, the noble metal balls are respectively contacted with bowllike recesses formed in the base surface of the metal plate. YAG laser beam is irradiated on the metal plate to weld the metal plate with the noble metal ball. Then the metal plate is sheared in a determined shape to form resilient strips. The present invention can improve welding operation efficiency and the reliability of welded portions. Since the metal plate being wider than that of the resilient strip receives beam, the metal contact mounting jig can be prevented from damage due to beam welding. | ||||||

| 75 | Method for attaching a flexible connector | US645362 | 1991-01-24 | US5093988A | 1992-03-10 | James A. Becker |
| A flexible electrical connector is attached to a movable contact finger and a stationary termianl by placing the components in a work chamber and positioning a first end of the flexible connector against an attachment surface of the contact finger, preferably in a perpendicular orientation. After evacuating the work chamber, the output of an electron gun is directed toward a joint formed between the flexible connector and the contact finger. The electron beam forms a weld zone which fuses the the flexible connector with the contact finger without degrading the flexibility of the connector or the mechanical strength of the contact finger. A second end of the flexible connector is positioned against an attachment surface of the stationary terminal, such as in a parallel orientation, and attached in a similar manner. | ||||||

| 77 | Enclosed externally actuated switch assembly | US931531 | 1986-11-14 | US4762972A | 1988-08-09 | John O. Roeser |
| A precision subminiature, snap action switch and an externally actuated, heavy duty, spring loaded self-return type operator therefor are enclosed within an hermetically sealed housing. The operator employs a switch actuating cam having shoulders cooperable with shoulders on the interior of the housing to define the limits of cam movement, said cam also having a shoulder cooperable with a shoulder on a switch lever to trip the switch upon movement of the externally actuated operator shaft a precise amount away from its at rest position. A connector/switch subassembly sealingly closes a housing opening, provides a rigid, precision mounting for the switch, and also provides external electrical connections for the switch. The operator has an externally projecting shaft which extends through a shaft bearing/rotary seal assembly employing a silicone rubber O-ring member and oil for lubricating a shaft bearing and the O-ring member, there being additional polytetrafluoroethylene O-ring members which prevent escape of the lubricating oil. An end cap sealingly closes another housing opening, provides a bearing for the inner end of the operator shaft, and exerts a predetermined stress on the operator spring. The structure lends itself to a simplified fabrication method. | ||||||
