Keyed receptacle for accessory-host interface

Keyed plug for accessory-host interface

A handle for an electronic instrument housing includes an elongated grip portion. The grip portion includes two elongated elements each having opposed ends. The elements are connected to each other to form an elongated chamber. An elastomeric layer encompasses an intermediate portion of the grip portion, and the grip portion has a vent aperture communicating with the chamber. The vent aperture may be beyond the elastomeric layer, at one or both ends. One of the elongated elements may form a channel with tapered edge surfaces receiving the other element, so that pressure of elastomeric molding tends to wedge the parts together to form a seal against incursion of the elastomer.

Molded instrument handle and method of manufacturing

A attachable/detachable probing tip system () has a housing () that includes a probing tip mounting member () and opposing substantially orthogonal attachment () arms extending from the probing tip mounting member. The attachment arms define an inner surface of the probing tip mounting member in which is disposed at least a first a non-compressive set, resilient member (). First and second probing tips () are disposed over the non-compressive, resilient member () and secured to the housing by latching means (). The attachable/detachable probing tip system allows mounting of the probing tips () to probing contacts on a device under test without a probe body or probing tip member () being attached. The attachment arms () allows a probe body or probing tip member () to be attached and detached to the probing tip system (). The probing tip member () includes contact pins that engage contact areas () of the probing tips ().

An attachable/detachable variable spacing probing tip system has a housing that receives pivoting probing arms. Each probing arm has a support member and a probing arm portion of a flexible substrate having a conductive trace thereon. One end of each conductive trace is coupled to a probing contact and the other end coupled to an electrical contact pad on a electrical contact pad portion of the flexible substrate. Each of the probing arm portions has a generally S-shaped fold therein extending from the support members to the electrical contact portion of the flexible substrate. The housing includes means for pivoting the probing arms. The rear surface of the housing has a resilient member disposed therein. Latching means in the housing secures the electrical contact pad portion of the flexible substrate to the rear surface of the housing. Opposing attachment arms from a rear surface of the housing.

Housing for test and measurement instruments

A coaxial cable 24 has an outer conductor 74 surrounding an inner conductor 70. A portion 76 of the inner conductor 70 is stripped of insulation and extends beyond the end of the outer conductor at a cable end 30. A circuit board 12 has a major surface and defines an elongated slot 34. A connection end of the slot is defined by a stop portion of the board 36, and a conductive pad 60 is provided on the board surface adjacent the stop portion at the end of the slot. The stripped portion 76 of inner conductor 70 is connected to the conductive pad 60, and at least a portion of the outer conductor 74 is received in the slot, and may be connected to another contact on the board. The stop portion of the slot is defined as a peninsular connection tab 54 by an elongated hole 50 formed on each side of said stop portion 36 of said slot. The distance between the sides of the conductive pad 60 and the near edges of the elongated holes 50 is selected to provide a predetermined transition impedance.
