Abstract:
A method (10) of forming an electrically conducting feedthrough. The method (10) comprises a first step (11) of forming an electrically conductive structure (21) comprising a sacrificial component and a non-sacrificial component. At least a portion of the non-sacrificial component can then be coated with a relatively electrically insulating material (35) prior to removal of at least a portion of the sacrificial component from the electrically conductive structure. The structure of the feedthrough provides electrical connection through the wall of a housing of an implantable component while preventing unwanted transfer of materials between the interior of the component and the surrounding environment.
Abstract:
Disclosed is a device for automatically mounting a crimp-style terminal on a connector housing which can have one or more vacant cavities. The mounting device is to be applied in production in which connectors can have varying numbers of terminals. Housings are accurately fed by a plurality of parts feeders and guides. Empty housings and housings with inserted terminals are held, respectively, by separate magazines. Terminals are individually cut off from a terminal hoop and individually set into insertion positions in front of a housing. After all terminals have been set, the terminals are inserted into the cavities all at once.
Abstract:
A terminal feeding unit reducing preparation time and adapted for multi-item and small-lot production of wire harnesses and a multi-crimping apparatus employing the same are disclosed. Plural terminal feeding units (210) are incorporated into the multi-crimping apparatus (20). Each terminal feeding unit (210) has a carrier cutting section for severing a terminal portion (BS) from a terminal belt (B), a crimping section (214) located at a pressing position (A), and a feeding section (215) for feeding a terminal (T) to the crimping section (214).
Abstract:
An IC sheet cutting press (B) pertorms a series of press cutting operations to separate IC's trom an IC sheet while feeding the IC sheet stepwise. In the IC sheet cutting press (B) a series of press moids and an IC feed mechanism are mounted on a common die set to constitute a single press mold unit (B1). When a different type of IC sheet is to be machined, the entire press mold unit (B1) can be exchanged with another one, so that various adjustments, e.g., adjustment of arrangement intervals of the press molds or a feed interval of the IC sheet can be omitted, and the operating efficiency of the cutting press (B) and hence the compatibility are improved. An IC sheet processing apparatus in which the IC sheet cutting press (B) described above is combined with an automatic IC sheet loading unit (A), an IC lead bending press (C), and IC storage unit (D) for storing IC's after the lead bending operation, allows automatic IC sheet processing including the cutting operation of IC's from the IC sheet over a long period of time.
Abstract:
Wire stripping and crimping tools are combined in modules (10, 16) movable along parallel rails (18, 20). An individual preparing a cable slides a particular tool module in front of a work station where each wire, requiring the same contact, is first stripped (62) then moved to an adjacent crimper (64) where a contact is crimped thereto. A second module carrying a second type of contact is then positioned into place and the cycle is repeated for those wires requiring fastening of the second type of contact thereto. By sequentially moving different modules to the cable, the entire cable becomes dressed in situ.

Abstract:
A contact (18) for use with a chip carrier (12) and a method for inserting of same into a housing is taught. Briefly stated, the device includes a contact (18) which is shaped similar to a tuning fork or U with a carrier strip (60) parallel to the arms (30, 32) of the contact and a pivot arm (40) interconnecting the carrier strip to the arms of the contact and having an interconnection member (41) perpendicular to the carrier strip and adjacent the lower part (38) of the tuning fork type contact. The contacts in carrier strip form are inserted into the housing by a feeder/cutter (66) which after insertion of a contact (18) into the housing (10) severs the adjacent portion of the carrier strip from the contact with the housing then being indexed (58) for insertion of the next contact.
Abstract:
Apparatus (10) mass terminates wires (12) to an automatically fed strip (22) of terminals, then mass inserts terminals on leading ends into cavities in a connector housing. A shuttle (14) having telescoping wire guide tubes and a wire clamp reciprocates to deliver wires (12) with leading ends in a straight array axially at a first fixed spacing to an operating zone and then to an insertion station. The telescoping tubes collapse to extrude leading ends of wires (12) into the operating zone where the wires (12) are deflected laterally of their axes various amounts and rolled into grooves in a template of the compensator (80) which restores the leading ends to a straight array at a second fixed spacing for termination to a strip (22) of terminals at the second fixed spacing. Shuttle (14) then retreats as tubes expand to draw in terminated wires, and then advances to insert terminals on leading ends into cavities at first fixed spacing in a connector housing. Clamp is released and shuttle (14) retreats over stationary wires (12) until wires (12) are exposed to strip and shear blades (40) remote from housing.
