  • Patent number: 4252399
    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.

  • Patent number: 4245297
    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.

  • Patent number: 4239321
    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.

  • Patent number: 4236302
    Abstract: A crimping apparatus or machine is disclosed in which electrical contacts of any one of a variety of conformations are fed from a receptacle or reservoir which holds a supply of contacts of selected conformation. The contacts are fed seriatim from the receptacle and are oriented and advanced to a crimping mechanism where each contact is selectively crimped to the end of an electrical cable. The receptacle includes a vibratory container which can be supplied with a plurality of contacts in a random array and the container is vibrated whereas the contacts are fed outwardly from the container along a helical path leading from the bottom of the container to an orienting mechanism. The orienting mechanism includes a downwardly inclined ramp connected to the container to be oscillated therewith so that the contacts move down the ramp one at a time due to vibration and gravity toward an advancing mechanism. The advancing mechanism is selectively actuatable and feeds the contacts seriatim to a crimping mechanism.

  • Patent number: 4233478
    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.

  • Patent number: 4232926
    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.
