Abstract: A lever-type connector has first and second housings (10, 20) that can be mated with one another. A lever (30) is mounted rotatably on the first housing (10). A cam groove (35) is formed on the lever (30) and engages a follower pin (22) on the second housing (20) to connect the housings (10, 20). The cam groove (35) has steep surface area (45) whose distance from a center of rotation of the lever (30) decreases at a higher rate than the other areas of the cam groove (35) and is formed at a position of the cam groove (35) slightly before a terminus end (35B). Thus, an operation resistance peaks when follower pins (22) reach the steep surface areas (45). This peak operation resistance is larger than a sum of a resistance required to engage a lock (41) with a projection (26) and a connection resistance acting between housings (10, 20).

Abstract: A ZIF socket (1) includes a base (10), a cover (20) slidably mounted on the base, a plurality of conductive terminals (30) received in a plurality of passageways (12) defined in the base, and an actuation protection device (24). The base defines a recess (16) at one end thereof, and the cover defines a through slot (22) at one end thereof corresponding to the recess. The actuation protection device includes a tenon (240) insert-molded in the cover, and a stop (242) protruding upwardly from the tenon. When an actuation tool (5) actuates the cover to slide between a first position and a second position, the actuation tool directly abuts against the actuation protection device. Therefore, the actuation protection device protects the cover and an associated CPU from being damaged by the actuation tool. Accordingly, the ZIF socket is apt to have an extended cycles lifetime.

Abstract: A telecommunications server comprises a switch/larch mechanism for use in online removal or insertion of a peripheral card, such as a PCI card. A bulkhead is adapted for mating engagement with a bulkhead mounting bracket of the peripheral card when the peripheral card is installed in the switch/latch mechanism. A doorbell switch having a vertical range of motion is manually depressed to signal the server and commence an orderly shutdown of the peripheral card in advance of online replacement of the peripheral card. A panel switch provides a mechanical lock retaining the peripheral card in place, and also function as a backup power interrupt device to protect the peripheral card in the event that depression of the doorbell button does not result in an orderly shutdown of the peripheral card.

Abstract: A telecommunications electrical connector positions the contacts in a manner to reduce crosstalk problems. An insert assembly positions the spring contacts within a jack for electrical contact with the contacts of a plug. The insert assembly staggers the relative positions of adjacent spring contacts in the y-direction, and staggers the spring contact pivot points in the x-direction, yet maintains a common contact region for all the spring contacts for contacting the contacts of the plug. The distal ends of alternating spring contacts are positioned so as to increase the isolation between adjacent springs. The insert assembly includes selected air passages between spring contacts mounted to the insert assembly to increase isolation and selected dielectric to increase crosstalk cancellation.

The protection cap is defined in a box shape, which can be molded by one or more molding dies that can be removed parallel to an engagement direction of the protection cap with the connector.

Abstract: A PC card has a plastic frame provided along the periphery of a substrate. Metal plates, such as stainless steel plates and the like, cover both surfaces of the substrate and are attached to the plastic frame. External surfaces of the metal plates located in an area on the opposite side of a connector and which are touched by a person's hand are covered by an insulation tape, so that, even if a person charged with static electricity touches the PC card when the PC card is inserted or withdrawn from an external apparatus such as a personal computer (PC), the static electricity (charge) of the person does not flow into the external apparatus. Thus, malfunctions or erroneous operations of the external apparatus do not occur.
