Abstract:
A holder for an electrical or electronic component includes a body formed of electrically non-conductive material. The body is generally U-shaped having a pair of laterally spaced arms bridged by a bight. Conductive tracing on the arms establishes an electrical connection between the component and a printed circuit board when the holder is electrically connected to the printed circuit board and the terminals of a component contact the arms.
Abstract:
A cable strain relief device is described comprised of a pair of disks each having an opening therein sized to allow a cable to be passed therethrough; and an arrangement to maintain the disks in a position relative to one another such that the openings are proximate and offset whereby cable passed through the openings is kinked and retained therebetween. The disks may be identical, the opening in each disk being offset from the disk center. The disks are positioned relative to one another to offset the openings therein. The preferred arrangement to maintain the disks in position relative to one another is a backshell and backnut assembly. The cable strain relief device, when used with a plurality of electrically conductive sheathed cables, provides, where electrically conductive disks are used, an electrically conductive pathway between the plurality of cables to ground.
Abstract:
A plug and an adapter are provided for use with an existing electrical receptacle which has a sleeve extending from a mounting base, with a conductive pin within the sleeve. The adapter has a cylindrical collar receivable snugly over the sleeve of the receptacle, and includes a flange for maintaining the collar in a predetermined position on the sleeve. The plug is elongate, with a first end having a recess for receiving the cylindrical collar, the first end also having an electrically conductive contact member to engage the contact pin. The plug and adapter include retaining means for retaining the plug to the adapter and to permit selective engagement of a plug and retaining means to prevent making incorrect connections between selected plugs and electrical receptacles. The plug further includes attachment means for connection to a cable.
Abstract:
A female power contact which is energized only upon insertion of a male plug. The contact includes a plunger which is biased toward a position which blocks accidental finger insertion into the contact. The plunger also contains sharp points on its outer edge to further prevent accidental finger insertion into the contact. However, insertion of the male plug into the female power contact, against the spring bias, causes the plunger to depress the spring in order to produce an electrical connection between the male plug and female contact.
Abstract:
An electrical terminal block for a high wattage high intensity projection lamp, and use thereof. The electrical terminal block is connected to an electrical power supply and has an orifice for plug-in of cable that forms part of such a lamp. The terminal block reduces premature lamp failure.
Abstract:
A finger is provided on the backshell extension of a heavy duty multi-pin connector to provide an attachment point for a strain relief band. The strain relief band prevents strain on a conductor bundle in response to flexure of a protective hose which is mounted on the backshell extension. The strain relief band may be similar in construction to the hose band which is used to secure the protective hose on the backshell extension.
Abstract:
A coupling guard insures that a plurality of plugs are coupled to plural receptacles in a desired sequence. An array of cam rings which rotate in unison with the rotation of mating plugs are designed to be locked against rotation unless the rings are rotated in the desired sequence. In one embodiment, cover plates coupled to the cam rings cover the entrance to the adjacent receptacles and are removed from the entrance of the receptacles by rotation of the cam rings.
Abstract:
Disclosed is a heat staking process using a configuration to join two conductive yarn traces or pads by piercing them with a thermo plastic stud shaped somewhat like a rivet with a pointed post to pierce the fabrics. A properly designed tool can be lowered to meet the pointed tip of the stud and by using the proper heat and proper compression will join the two fabric pieces mechanically and electrically. The heat and compression formed stud 50 will provide mechanical strength and actually seal the connection if so required.
