Abstract:
The disclosure relates to a filter assembly securable in a panel by driving the filter assembly into an aperture in the panel, the filter assembly automatically locking itself in the panel, yet being easily removable from the panel by means of a tool. This is accomplished by providing a ceramic filter encased within a body of non-resilient electrically conductive material having a drivable region, the body fitting within a tapered locking ring having fingers with internal diameter across the fingers smaller than the diameter of one section of the body, the fingers being driven outwardly by movement of the body thereagainst within the panel to lock the fingers on the panel. The body includes an enlarged flange portion which is utilized for driving the assembly into the panel as well as to lock the assembly in the panel in conjunction with the fingers. The assembly is removed by means of a tool returning the fingers to the pre-locking position.
Abstract:
A plurality of electrically conducting socket-type terminals are provided on a common carrier strip. The sockets comprise sleeves of conducting material which contain a resiliently expansible receptacle which forms a female terminal. Each receptacle is freely expansible internally of a corresponding sleeve. This is accomplished by providing a pair of opposed spring arms of the receptacle which are free to deflect resiliently toward and away from each other internally of a corresponding sleeve. Positive connection between a corresponding sleeve and a receptacle is accomplished totally externally of the receptacle in order to prevent undue constraint of its resilient expansion. Such a connection is accomplished by providing a tab integral with a non-deflectable portion of a receptacle, the tab projecting outwardly of the receptacle for connection to the enclosing sleeve. The free ends of the spring arms protrude outwardly of the sleeve to provide an enlarged flared entryway to the receptacle. The free ends are also exposed to allow visual inspection of their correct alignment. The ends are further widened to provide relatively large target surfaces for receiving and funneling the male electrical terminal which is to be connected within the receptacle.
Abstract:
A tap-type connection for a multi-conductor cable comprises a multi-contact connector disposed beside the cable. The wires from the cable extend laterally with respect to the cable axis and are connected to terminals on the rearward side of the connector. The wires extend from these terminals back to the axis of the cable and become part of the cable again. The tap is contained in a housing comprising two panel-like members hinged together clamshell fashion. The housing has inlet and outlet openings for the cable along one side and, in its closed condition, is assembled to the rearward side of the connector so that the laterally extending wires are contained in the housing.
Abstract:
The invention relates to a miniature connector having a dielectric housing which is flexible for conforming to irregularities in the printed circuit board. A plurality of contacts are mounted in the housing. Each of the contacts includes a leaf spring portion in the form of a cantilever beam integral with the base portion and latched to the housing. The housing includes an opening at one end allowing for receipt of projecting posts mounted to a printed circuit board. When the housing is mounted on the surface of the printed circuit board the posts are electrically attached to the base portions of the contacts. The housing includes additional openings for pluggable receipt of male electrical terminals wedgingly engaged between the posts and leaf springs which cooperate to engage and grip the terminals.
Abstract:
An electrical terminal structure is disclosed which is provided with a flow deposited quantity or band of solder adhered to a selected portion of the terminal and limited from spreading over the surface of the terminal by the presence of a soldernonwettable material adjacent to but not necessarily touching the terminal. A method of mounting the banded electrical terminals in plated apertures provided in a substrate is also disclosed, wherein the solder bands are applied to the terminals according to the above mentioned application technique. A technique of flattening the solder bands, and the resulting terminal structures having flattened solder bands adhered thereto are also disclosed. Flattening of the solder bands facilitates insertion of the banded terminals into the plated apertures by changing the shapes of the solder bands and by reducing their structural integrity though the creation of numerous hairline fractures.
Abstract:
This invention relates to a receptacle for connecting a terminated coaxial cable to circuits on a printed circuit board. More particularly, the receptacle consists of a stamped and formed shell member which contains a stamped and formed center contact and which also terminates the ground circuit to the board. The center conductor contact is embedded within a dielectric housing electrically isolating it from the shell member. Both the shell member and center contact contain formed biasing means to frictionally retain the coaxial cable.
Abstract:
An improved matched impedance and power transmission cable assembly is disclosed having a pair of flat flexible cables. Each cable comprises a flexible insulating substrate with circuitry on both sides thereof, each covered by an insulation layer. The cables are arranged in stacked fashion with shielding circuitry on the exterior surfaces. The pair of cables is enclosed in a protective sheath and terminated with appropriate terminal means. The circuitry on both sides of each of the two flat flexible cables has a periodic repetition rate so that the cables can be terminated at suitable intervals thus obviating the need to form such cables in a multiplicity of different lengths.
Abstract:
A method for mechanically and electrically connecting conductors to multi-contact electrical connectors having rows of aligned terminals. Predetermined conductors can be electrically and mechanically connected to predetermined terminals in each of the separate connector housings positioned beside each other by locating the intermediate portion of each conductor over corresponding aligned terminals in the housings, moving the conductors into the slots of the terminals, and cutting out the section of conductor which extends between the terminals.
Abstract:
Housings for electrical connecting devices, such as terminals on the ends of wires, are provided in the form of a continuous strip of unassembled housings in side-by-side relationship. The leading housing of the strip is applied to a connecting device by means of an apparatus which assembles the housing to the connecting device and ultrasonically welds meeting edges of the housing to each other.
Abstract:
The present invention relates to a electrical connector shield wherein one end retains an electrical connector and the other end contains an opening defined by arcuate portions and a curved inner wall against which electrical leads emanating from the connector are simultaneously clamped and deflected away from the shield at an angle.
