Abstract:
An electrical connector may have a housing which has one or more printed circuit board assemblies. Each printed circuit board assembly has a plurality of signal traces and ground traces. Attached to the printed circuit board assemblies is a base. Disposed within one side of the base are a plurality of slots for receiving the printed circuit board assemblies. The opposing side of the base may have a plurality of pockets for receiving a plurality of fusible elements, which are preferably solder balls. Holes in the base provide a passage from the slots to the pockets. The solder balls are connected to the signal trace ends which extend into the base slots by metallic elements, such as contacts or solder paste.
Abstract:
A receptacle comprises a receptacle housing having a body, a plug interface portion extending therefrom, and a contact support member with pivot areas formed therein for urging contacts disposed in the housing into alignment. A receptacle further comprises a shielding shell having cantilevered beams formed therein. The shielding shell has a projection extending therefrom for contacting a latch arm extending from the receptacle housing. A shielding gasket is disposed around the shielding shell and has overlapping rows of beams extending therefrom. The shielding gasket also has a projection extending therefrom that is situated in a channel formed in a latch arm. The latch arm is formed as part of a latch plate comprising a latch bar, two latch arms, and at least one projection for contacting ground.
Abstract:
Disclosed herein are methods and apparatus for providing as strain relief (18) for use in the assembly of an electrical connector (14) on an end of an electrical conductor (16) having at least an outer braided portion (24), which may be surrounded by an insulating cover. The methods and apparatus disclosed herein provide a low cost approach for installation using minimal tooling, while providing a precise and robust relief that ensures electrical performance.
Abstract:
A wedge connector with a shell (10) and a wedge (12). The shell (10) has insulation piercing sections (46) to pierce through insulation of electrical conductor cables (A, B). The wedge has a frame and piercing supports movably attached to the frame. The piercing supports pierce through insulation of the cables such that conductors in the cables are directly contacted by both the shell and the wedge.
Abstract:
An electrical wedge connector with a wedge (12) and a shell (10). The shell (10) is a one-piece sheet metal member with a conductor piercing section (46). The conductor piercing section comprises a tab (46a) of the sheet metal member at an end of the shell that is folded about 180 degrees inward against an interior side (52) of the shell. The tab has a section that projects in an inward direction generally perpendicular to the interior side and has teeth at an end edge thereof.
Abstract:
A hydraulic drive system for a battery operated portable compression tool. The tool has an electric motor. The drive system has a self-regulating variable displacement pump with a rotatable conduit frame having radial conduits, pistons reciprocally located in the conduits, and a ring bearing surrounding the conduit frame in an eccentric adjustable location. Ends of the pistons are located against the inside of the ring bearing. A valve plate located against a front end of the rotatable conduit frame to control entry and exit of fluid into and out of the conduit frame as it is rotated.
Abstract:
In an electrical connector, cross talk between signal contacts in adjacent linear columns and rows may be reduced by changing the size of the lead portions of the contacts extending within a leadframe housing. For example, the height of the ground contact lead portions may be increased to further isolate signal contacts in adjacent columns from interfering electrical fields. The height of the signal contact lead portions may be decreased in order to accommodate the larger ground contact lead portions without increasing the overall size of the connector. Smaller signal contact lead portions may reduce the overall length differential between signal contacts in a differential pair, thereby minimizing signal skew.
