Abstract: An electrical terminal or contact element for use in an electrical connector, having a resilient tab for retaining the element in the connector housing. The tab is attached to a central portion of the element and extends diagonally through the center of the element at an acute angle to the longitudinal axis of the element. A free end of the tab extends beyond the element for engaging a shoulder of the housing after the element is inserted through a passageway in the housing. The free end of the tab may be deflected inwardly by means of a pin-like tool to disengage the tab from the shoulder and allow removal of the element from the housing. A stop surface in the central portion of the element prevents deflection of the tab beyond its elastic limit, thereby preventing damage to the terminal element.
Abstract: A mechanical element positioning control system. Position measuring means supply actual position and a computer supplies desired position as the least significant 11 bits of an 18 bit signal to corresponding digital to analog units, each comprising an 11 bit register and an 11 bit digital to analog converter. A differential amplifier compares the outputs of the digital to analog converters and generates a position error signal. A threshold circuit operates to complement the most significant bit of the D/A registers when exceeding of a maximum allowable analog error occurs. A servo system responsive to the position error signal positions the mechanical element to eliminate difference between desired and actual position. By eliminating the seven most significant bits representing desired and actual position, the total range is divided into 2.sup.7 separate fields so that D/A units of practical accuracy may be employed to make feasible a positioning control system of required accuracy and range.

Abstract: Improved modular interface connectors and connector assemblies incorporating such connectors are disclosed for interconnecting telephones and telephone signal equipment. The modular connectors of the invention include improved mounting structures which permit each connector to be slidably mounted on a support member in at least two alternate orientations and to be retained at any position between two spaced shoulders of the support member. In addition, the modular connector is preferably an integrally molded plastic unit configured to permit its fabrication in a single-action mold. In one embodiment, the interface connector further includes a removable comb member which separates and aligns the active portions of the connector contact elements and prevents access through the entrance aperture of the connector to the free ends of the contact elements.
Abstract: The invention relates to a sheet metal contact element which can be inserted into a chamber of an insulating housing and comprises a rear terminal portion for connecting a conductor, a forward contacting portion, and an intermediate locking section with at least one stamped, outwardly protruding locking tab to anchor the contact element in the chamber. When a strong tensile load is applied to prior art contact elements, the locking tabs, which usually are bent slightly outwardly, are deflected toward the interior of the contact element and permanently distorted. Thus, the contact element is no longer kept in the proper axial position, and the damaged contact element must be replaced. This problem is solved by the present invention by providing a reinforcing pin inserted into the inner cavity of the locking portion. The reinforcing pin prevents the locking hook from being deflected into the interior of the contact element when a load is applied.
Abstract: An electrical connector is disclosed and has complementary receptacle and plug connector members, each member having a hollow shell containing a conventional insulating insert which houses electrical contacts. A rotatable coupling ring is carried by the plug and is engageable with the receptacle for mating the connector members and holding the contacts in electrical engagement. A radially deflectable detent leaf spring is carried on an inner circumferential portion of the coupling ring, and the leaf spring has a radially extending detent protrusion intermediate the ends thereof and engageable with an annular array of ratchet-type detent teeth on an outer circumferential portion of the connector plug. The leaf spring is comprised of a pair of superimposed leaf portions joined together integrally at adjacent ends thereof by an enlarged loop portion. The loop portion is positionable within an axially exposed mounting recess at one end of the coupling ring.

Abstract: Circuit transfer apparatus is described for use in transferring from time-responsive control to temperature-responsive control, and vice-versa, in a microwave oven. The low cost, miniaturized apparatus is mounted to the wall of the oven's cooking cavity and is operated from within the cavity by insertion or withdrawal of the cable plug of the heat-sensitive food probe. The probe plug cooperates with insulative elements to activate spring-leaf sheet metal contacts mounted in the housing of the apparatus, to thereby effect the circuit transfer. The housing also serves as mechanical retention means for the probe plug.
Abstract: An electrical connector for attachment to a printed circuit board which allows stacked printed circuit boards to be positioned closer together than previously possible. The connector comprises a housing, one surface of which is mounted against one side of the printed circuit board, and at least one resilient female contact having a terminal end extending through a passageway in the housing and attached to the printed circuit board. An intermediate portion of the female contact is bent such that the portion is substantially parallel to the printed circuit board. The other end of the terminal is folded over to form a wiping surface for contacting a mating male contact extending from an adjacent printed circuit board. The housing includes an opening adjacent the contacting end of the female contact to allow passage of the male contact through the housing and into engagement with the female contact.
Abstract: This invention relates to a locking mechanism for coupling anduncoupling electrical connectors. In the prior art, because of the large number of electrical contacts contained within the male and female connector parts, the insertion and extraction forces for coupling and uncoupling the connector parts are often sufficiently high to damage the supports for the connector parts. This is especially true with printed circuit boards wherein the insertion and extraction forces are applied normal to the flat surface of the board. The present invention overcomes this deficiency by providing an improved locking mechanism for coupling together and uncoupling mating electrical connector parts. One connector part is provided with an actuator pivotally mounted for applying force in both an insertion and an extraction direction as the actuator pivots. A projection on the other electrical connector part receives the insertion and extraction forces for coupling and uncoupling the connector parts, respectively.
