A clip for connecting an electrical component to testing equipment, comprising a plurality of conductive elements mounted in a holder in positions to engage the respective leads of a multi-lead electrical package and to connect said leads to components of the testing equipment, the conductive element holder comprising flat plates joined by a deformable web to constitute an integral core unit, the upper and lower surfaces of said unit being normally non-parallel and the conductive elements being fixed on said surfaces by upper and lower covers, the conductive elements projecting beyond the rear edges of the covers and terminating within the covers at the front end.
Improved clasp structure for use with both planar-type and curvilinear button-type external electrode sensors for electrical transfer of ECG signals. An integral connector on this universal-type clasp structure provides mechanically interlocked connection with a shielded cable to significantly reduce signal interference from external electrical sources. This new clasp structure can be used and reused in a sterile environment; it can be sterilized in a steam autoclave and is partially covered with sterilized surgical tubing so as to prevent pick-up of stray patient signals.
A test clip and grounding adapter assembly comprises a conventional integrated circuit test clip of a type having parallel arrays of signal conductors retained in a pair of molded plastic arms biased closed on the leads of a unit under test. An adaptor in accordance with the invention having twice as many conductors as the test clip interconnects the test clip and a ribbon cable. The additional conductors within the adaptor interposed with the signal conductors in the clip are grounded to electrically shield the signal wires.
The holders are attachable to the edges of planar support surfaces for music and serve to hold the music in place against the effects of wind, gravity and characteristics of the music material. Each holder comprises attachment apparatus and a spring arm extending from it to contact the music. In a preferred embodiment the spring comprises an arm portion and a pivot portion which, when the spring is relaxed, is at an 80.degree. angle to the arm portion. The pivot portion is carried in a hole in the attachment apparatus, the hole and pivot portion being inclined at a 3.degree. angle off of normal to the planar support surface angled toward the leafed material. The arm portion can thus be pivoted so that its end is either in or clear of the locations in which music is placed to be held. Height of the arm portion is adjustable by sliding the pivot portion in the hole in the attachment apparatus, thus accommodating variations in the thickness of the music material and allowing the arm to be positioned to lie flat against held material to allow free turning of unheld material.
An electrical assembly in which electrical connection is made to a device having two laminar electrodes and a laminar element between the electrodes, preferably a circuit protection device in which a PTC conductive polymer element is sandwiched between two metal foil electrodes. Connection is made to at least one of the electrodes by a resiliently deformed clip having an active arm which contacts one of the electrodes, and a passive arm which is not in conductive contact with the other electrode. Preferably there is an auxiliary member between the active and passive arms of the clip. The auxiliary member can be an insulator, or a conductive member which is spaced apart from the other electrode but secured to the same face of the PTC element as the other electrode.
A circuit test clip with a plurality of conducting elements making simultaneous electrical contact with an equal number of terminals on a miniaturized circuit formed on a printed circuit board. The test clip is useful for inspection or otherwise testing such miniaturized circuits.
