  • Patent number: 4444454
    Abstract: A plug connector is disclosed which is particularly useful with a coaxial cable having alternating layers of braided shield and foil tape between an outer insulating plastic jacket and an inner dielectric covering a center conductor. The connector has a housing, with an internally threaded end having a predetermined thread pitch for manual "twist-on" connection to the outer plastic jacket of the cable, and a center contact having an internally threaded opening with a thread pitch different from that of the end of the housing. The center contact of the connector is designed to require greater "twist-on" torque, to effect a good connection to the center cable conductor, than that torque required to effect assembly of the connector housing and cable jacket.

  • Patent number: 4366459
    Abstract: A miniature magnetic latch relay including a support header, a permanent magnet, an armature in pivotal contact with the magnet and engaging a pair of switch contacts movable between corresponding pairs of fixed contacts, the armature being pivotally movable between two stable positions in response to selective energization of two electromagnetic coils, and a frame mounted in spaced relation to the header having magnetic core sections for the coils and pole piece sections for the armature, the frame supporting the permanent magnet and having an opening through which the magnet extends for pivotal contact with the armature. A barrier of non-magnetic material in the frame around the opening resists magnetic flux flow between the permanent magnet and the frame portion near the opening thereby forcing magnetic flux to flow between the permanent magnet and the armature.

  • Patent number: 4327344
    Abstract: A mechanically latchable solenoid having a single coil and a single-piece armature or core plunger having a latch pin fixed thereto. The plunger is moved to a first, retracted position by energization of the coil with a pulse of either direct or alternating electric current. A spring-biased mechanical latch latches the plunger in the retracted position. A subsequent energization of the coil with a current pulse unlatches the plunger so that the plunger is returned to its original, unretracted position by a non-magnetic external force, such as that provided by a plunger spring. The latch is in the form of a lobed cam which is mechanically moved out of its normal unlatched position by the latch pin when the coil is first energized to attract the plunger from its unretracted to its retracted position. When the plunger has moved a predetermined portion of the distance to its retracted position, a lobe of the spring-biased cam engages the pin to prevent the plunger from returning to its original position.

  • Patent number: 4322701
    Abstract: A magnetic circuit for a miniature relay comprising a coil carried by a magnetic frame and an armature adapted for movement in response to energization of the coil to close an air gap between the armature and a pole face of the frame. A portion of the frame comprising a pair of supporting legs is sufficiently close to a core face portion of the frame to define a fringing flux path tending to divert flux from the useful flux path including the armature, air gap and frame. A barrier is provided in the fringing flux path of a material creating sufficient reluctance in that path to resist flux flow therethrough thereby increasing flux flow in the useful flux path to increase relay efficiency. The barrier can comprise non-magnetic material in the supporting legs, in the core face or in both.

  • Patent number: 4252996
    Abstract: Telephone coupling devices which are used to connect various devices into telephone networks without electrical connections require structure which will provide effective acoustic coupling with telephone handsets produced by a variety of manufacturers, many of which differ from each other not only in major dimensional characteristics but also in specific construction. An acoustic coupler having a dimensionally bi-stable flexible coupling element permits use of the coupler of the present invention with an unlimited number of telephone handset configurations.

  • Patent number: 4161816
    Abstract: A plurality of contact pins project from a flat header of a miniature relay for connection to a corresponding number of coaxial cables. A separate radio frequency adaptor is provided having a plurality of hollow cable connector receiving shells and a planar supporting base interconnecting the shells with the shells serving as RF shields for the header pins.The process of making the RF relay assembly includes mounting the header pins in a predetermined layout on the relay header, forming a one-piece adaptor by interconnecting the tubular shells in a pattern corresponding to the header pin layout and then securing the one-piece RF adaptor to the relay header with each header pin in a complementary shell and with each shell made common with electrical ground.

  • Patent number: 4133594
    Abstract: A connector is disclosed which features a bifurcated contact providing a pair of contact legs enveloped within an insulating body or housing having a conductor entry opening registering with the contact legs. The housing includes beveled cam shoulders adjacent its opening and which cooperate with the contact legs to automatically apply a predetermined conductor locking force upon inserting the conductor into the housing between the contact legs and which increase the locking force in response to a conductor withdrawal force being applied.

  • Patent number: 4101855
    Abstract: A miniature relay having an electromagnet assembly including a coil carried by a magnetic frame member which assembly is supported on a non-magnetic coil support member which in turn is secured to a header containing an arrangement of stationary and movable contacts and terminal pins. The magnetic frame member includes a core extending through and slightly beyond the coil and a pole piece outwardly adjacent the coil. An armature is held in position by the cooperation of spaced-apart holding elements depending from the electromagnet assembly which saddle a recess area in the armature, and a return spring carried by the header continuously urges the armature into saddle defined by the holding elements. The pull-in force of the electromagnet is enhanced by a mating tab and notch configuration of the pole piece and armature or by an end portion of the pole piece disposed to present increased surface area facing the armature.

  • Patent number: 4053195
    Abstract: A readily installed and removable coaxial cable connector assembly which is rendered theftproof by the provision of an end cap which may be manually thrust into an open end of a housing surrounding a coaxial cable connector coupling to close the open end of the housing and simultaneously render the coupling inaccessible. The end cap is releasably locked by a plurality of spring fingers formed on a leading end of the cap and movable with a snap action into an internal groove in the housing.
