  • Patent number: 5280716
    Abstract: A tool for crimping a terminal to an end of an electrical conductor has a movable fulcrum which reduces hand force required to operate the crimping tool. The tool includes main body having a handle end and a first jaw disposed remote from the handle end. A second jaw is pivotally connected to the main body between the handle end and the first jaw. The a second jaw cooperates with the first jaw to perform the crimping as the second jaw is pivoted toward the first jaw. A movable handle is operably connected to the second jaw to pivot the second jaw toward the first jaw. A driver link has a first end pivotally connected to the main body, and a second end of the driver link has a slidable connection with the movable handle. The slidable connection includes a pivot pin which is slidable in a slot defined in the movable handle.

  • Patent number: 5142771
    Abstract: Feeding apparatus for feeding articles, such as electrical devices, from a tube magazine comprises a frame for supporting the tube with a first end of the tube adjacent to a delivery station. The articles are fed by a flexible feeding member which has a first feeding member and located, at the beginning of an operating cycle, adjacent to the second end of the tube. The feeding member extends away from the second end and then in the reverse direction back towards the first end of the tube. The feeding member is moved through the tube by an actuator which comprises a resilient flexible tape or band. The actuator has a coiled portion adjacent to the second tube end and an end portion which extends from the coiled portion towards the first tube end. The end portion is secured to the trailing end of the feeding member.

  • Patent number: 5090116
    Abstract: A connector (10) having one or more arrays of elongate cantilever beam arms (22) of contacts (20) can have contact sections (26) on free ends (24) thereof soldered to respective traces (94) of a circuit element (90), by securing a lead frame (50) to free ends (24) which includes a corresponding plurality of fingers (56) extending from a carrier strip (52). On the finger ends (58) are affixed preforms (80,82) of solder; on the carrier strip (52) is defined a thin magnetic layer, transforming the brass carrier strip into a Curie point heater. When the carrier strip is subjected to RF current, it generates thermal energy which melts the solder preforms to join the fingers first to the contact sections (26) of the connector contacts (20), and in a remote location later subjected to RF current to reflow solder preform (82) to join contact sections (26) to traces (94).

  • Patent number: 4754536
    Abstract: The present invention relates to a method through which a machine is enabled to feed a preloaded electrical connector (10) on appropriate spacings to allow the termination of individual wires (W) in terminals (13) in the connector through a novel indexing feed finger (120) which is capable of engaging surfaces (A-E) on the connector which are different relative to a constant indexing stroke. The indexing finger includes surfaces (126-132) capable of handling more than one set of dimensions of more than one style of connector without adjustment. The invention further includes a mechanism (180) for bending a scored portion of terminals to effect a later removal of the terminal carrier strips.

  • Patent number: 4747209
    Abstract: A tool for aligning contacts of an electrical connector with conductive areas of a circuit board comprises a base member with comb means movably secured thereto. The comb means are movable between a first position and a second position to cooperate with the contacts of the connector to insure that the contacts are precisely aligned as the circuit board is inserted into the connector. Securing and alignment means are provided to allow the comb means to easily adjust to the contacts of individual connectors. As the comb means is brought into engagement with the contacts a space bar is provided to prevent the contacts from entering the recess into which the circuit board enters. The contacts are maintained in position as soldering occurs, ensuring that a positive electrical connection is affected.

  • Patent number: 4739550
    Abstract: A tool for aligning contacts of an electrical connector with conductive areas of a circuit board comprises a clamp for clamping the connector therein, a slide is movably mounted on the clamp and includes a comb between the teeth of which the contacts are disposed, and adjustment means moves the slide and comb thereby causing the comb teeth to move the contacts so that they are positioned in alignment with the conductive areas.
