Abstract: A low inductance electrical compression connector for a disc drive interconnecting conductors of a flex circuit to conductive traces on a PCB, the electrical compression connector having a dielectric housing with a plurality of spaced apart insulator portions and conductive compression contacts disposed between the insulator portions. The insulator portions, the dielectric housing and the conductive compression contacts form open ended deflection cavities disposable above the PCB. First ends of the conductive compression contacts and solderable to conductive traces on the PCB, while second ends of the conductive compression contacts are pre-load spring contacts disposable above respective deflection cavities. Inserting the conductors of the flex circuit beneath the pre-load spring contacts into the deflection cavities causes the pre-load spring contacts to engage the conductors of the flex circuit to secure the flex circuit against the printed circuit while providing electrical contact.

Abstract: Two lamp sockets (40, 42) on a wiring board (32) behind a switch assembly (18) have identical geometries. Each comprises a through-hole with a polarizing feature. Plural discrete contact pads (44, 46, 48, 50) are disposed on the board surface spaced apart around the margin of each through-hole. Plural discrete conductor traces (52, 54, 56, 58) are printed on the board surface to run from the respective contact pads. Each socket can accept either a first model (66) or a second model (68) of lamp assembly to make either socket a status indicator for the switch assembly or a nighttime illumination socket. A common wiring board can thereby serve different requirements for the locations of status indicator and nighttime illumination lamps.

Abstract: A press-in pin includes an elastic, cross sectionally bow-shaped press-in region having a bow section, two longitudinal sides and lateral flares at opposing locations on the two longitudinal sides. In a pressed-in condition, the press-in region rests against a bore wall only with the flares, but not with the bow section. Such a press-in pin has a very favorable resilience behavior and practically speaking, is only elastically deformed.

Abstract: A series of modular plugs insertable into a row of connector sockets mounted on a circuit board to be tested are secured to a specially designed support structure which enables the plugs to be simultaneously mated with the sockets to thereby substantially reduce the required test connection time and to enable the plugs to be coupled with and uncoupled from the sockets without subjecting the plug cables to appreciable handling stress. In one embodiment thereof the support structure may be manually moved toward the sockets to effect the coupling of the plugs with their sockets, and a movable latch plate member is carried by the support structure for use in simultaneously unlatching the inserted plugs from their sockets. In another embodiment thereof the support structure is stationarily secured to a specially designed test stand assembly which is operable to move the circuit board toward the stationary plugs to effect the desired plug/socket test interconnection.

Abstract: A safety jumper cable has two cable segments each with conventional terminal clamps on one end and a coupling on the other end. The terminal clamps are adapted to be secured to the battery terminals in the conventional manner. The cable couplings cannot physically be connected together by means of a positive fail-safe lockout unless the clamps are secured to the proper battery terminals. This lockout is provided by a normally extended, locked safety blade that is slidably mounted within each coupling. When the terminal clamps are attached to the proper battery terminals, the safety blades are unlocked and the safety jumper cable can be coupled together away from either battery and the danger of sparking and explosions. The safety jumper cable may also be provided with a manual override device.

Electrical contact elements extend partially into the bore for contact with the plug member when inserted, such contact elements having a leg part accommodated in one of a pair of first and second slots so as to extend from that one slot outwardly of the body for electrical connection. In this manner two similar insulating bodies of stackable electrical sockets can be stacked one on another so that the first and second slots of the overlying socket each overlie one of a first and second slot of the underlying connector and the leg part of the overlying connector which is presented for electrical connection is received through one of the first or second slots which is vacant of a leg part of the underlying socket for the leg part of the overlying socket to be presented for electrical connection from the underlying socket.

Abstract: An electrical connector comprises an insulative housing, a number of contacts, and a conductive shield enclosing the housing. The housing defines a number of passageways for receiving the contacts with terminal portions outwardly extending. The shield is integrally formed by means of stamping wherein a mating portion is further formed thereon by a drawing process. A fastening section fastens the shield and the mating portion together thereby defining a cavity for receiving the housing. By bending a rear wall of the shield the housing can be entirely enshrouded by the shield thereby providing excellent shielding capabilities.

Abstract: A selectable compatibility electrical connector plug has a substantially hollow housing member and a plurality of contact members extending from a cable connection end to a connector end. A circuit member having circuit components thereon is affixed within the housing with the circuit components being spaced from the contact members or leads. In open embodiment, actuator members contact the leads and project above the exterior surface of the housing. When the plug is inserted into a low performance jack, the actuator members force the leads against the circuit components to produce crosstalk and transmission loss characteristics of a low performance plug. When the plug is removed from the jack, the resilience of the leads forces the actuators up into a neutral position. The actuators may be buttons, toggles, or, in one embodiment, bowed portions of the leads which project above the surface of the housing.
