Abstract: A connector is provided that includes a female terminal with sacrificial portion. The terminal is configured to minimize arcing between a mating male terminal and an intended contact portion of the female terminal. The female terminal is configured such that arcs between the male terminal and the female terminal occur such that the sacrificial portion of the female terminal experiences any arcing while the intended contact portion remains suitable for reliably engaging the male terminal.

Abstract: A water-base wellbore fluid for use in subterranean wells that penetrate through a subterranean formation containing a shale which swells in the presence of water. The well bore fluid includes, an aqueous based continuous phase, and a shale hydration inhibition agent. One illustrative shale hydration inhibition agent is preferably the reaction product of a hydrogenation reaction of the product of the reaction of an aromatic amine with an aldehyde, preferably formaldehyde. Alternatively the shale hydration inhibition agent may be the reaction product of a hydrogenation reaction of the product of the reaction of aniline and formaldehyde. In one illustrative embodiment, the shale hydration inhibition agent is selected from the class of compounds known as polycycloaliphatic amines. The shale hydration inhibition agent may be present in the form of a free-base or preferably in the form of an acid salt of the disclosed amine compounds. The shale hydration inhibition agent is present in sufficient concentration to substantially reduce the swelling of shale drilling cuttings upon contact with the fluid.

Abstract: An electrical connector is capable of easy conversion from a receptacle connector to a blade connector. A dielectric housing includes an elongated receptacle for receiving a blade terminal of an appropriate mating blade connector. At least one connector terminal is mounted on the housing and includes a contact portion exposed in the receptacle to form a receptacle connector and for engaging the blade terminal of the mating blade connector. A bare blade member has a mounting end fixable in the receptacle in engagement with the contact portion of the connector terminal. A bare blade end of the blade member projects from a mating face of the housing to convert the receptacle connector to a blade connector.

Abstract: An electrical connector includes a dielectric housing having a terminal-receiving passage for insertion thereinto of a terminal. The terminal includes a cantilevered spring contact arm projecting into the passage for engagement by an appropriate conductor inserted into the passage. The terminal further includes an engagement arm projecting into the passage behind the cantilevered spring contact arm at a location to perform the dual function of providing an anti-overstress engagement surface for the spring contact arm and providing an engagement shoulder for an insertion tool which forces the terminal into the terminal-receiving passage of the housing. The passage is open-ended to allow the conductor to be inserted completely through the housing past the contact arm of the terminal and into the clearance hole of the printed circuit board.

Abstract: An electrical terminal pin is provided with a pin tip for insertion into a mating electrical female terminal, a hole in a printed circuit board or the like. The pin has an electrically conductive core plated with an electrically conductive layer. The pin tip is formed of a generally rounded pyramidal configuration defining four slightly curved convex sides joined at four edges converging at a pin end. Two opposite sides of the pin tip are non-plated. The other two opposite sides of the pin tip are plated with the conductive layer. Portions of the conductive plating layer overlap the edges of the pin tip in a smooth or rounded configuration to eliminate any sharpness thereof and to provide additional plated areas over the exposed core material. The pin tip is formed by a cutting and coining operation to form the configuration of the tip and to coin the overlapping portions of the conductive plating layer over the sharp edges of the pin tip.
