Abstract: A pin contact of a connector and a method of fabricating the pin contact which enables a substantial decrease of manufacturing cost, and smooth installation of the pin connector without a change in the pitch of arrangement at the time of press-fitting into a pin housing. A flat metal sheet undergoes blanking and pressing to form a narrow piece including a strip portion of decreased area of a fracture. Then an approximately L-shaped connecting portion is bent at right angles to raise the narrow piece sideways. Thereafter the strip portion of the narrow piece is pressed along the direction of rising, to thereby form an approximately cylindrical contact section. A raised piece at the rear of the contact section is provided with a locking section which faces approximately at right angles with the direction of arrangement.

Abstract: An electrical connector assembly 2 for use with a printed circuit board 6 includes an electrical connector 4, such as a standard miniature ribbon connector, and an injection molded lead positioning comb 48. Cantilever beams 54 in the lead positioning comb 48 form lead receiving slots 52 into which terminal leads 40 extending at right angles from terminals 26 inserted into a connector housing 8 precisely position rows of leads 40 for insertion into printed circuit board holes or on surface mount pads. The slots 52 on the lead positioning comb 48 face the connector housing 8 and the comb 48 is snapped to the housing from the rear. As the comb is snapped to the housing, the terminal leads enter the slots. Carrier strips 46 join terminals in each row during insertion of the leads into the slots to prevent deflection. The carrier strips 46 are removed after assembly of the comb 48 to the housing 4.

Abstract: An electrical connector assembly (100) that adaptively couples a radio frequency signal between two ports includes two electrically conductive elements (102, 104), a compliant member (106), and a matable housing (116). A first electrically conductive element (102) is disposed substantially within the matable housing (116) to provide connectivity to a first port. A circularly formed metal element (104) provides connectivity to a second port. The circularly (e.g.. cylindrically) formed metal element may be mounted to a printed circuit board by soldering a solderable surface (114) on an underside of the circularly formed metal element to a trace on the printed circuit board. The compliant member (106) is connected to both electrically conductive elements (102, 104) to provide mechanical stress relief therebetween during operation of the electrical connector assembly (100).

Abstract: A short-circuit chamber 15 is provided in a female connector housing 11, and contains a short-circuit part 16 provided with left and right-hand resilient arms 18a which normally make contact with female terminal parts 13 to establish a conducting state. A male connector housing 21 is provided with insulating pieces 25 which, when the male and female housings are coupled, enter between the female terminal parts 13 and resilient arms 18a to break the electrical circuit. Projections 18c engage with the rear edges 15d of openings 15c to establish an engaged state of the short-circuit part 16. Insertion of the insulating pieces 25 disengages the projections 18c from the rear edges 15d, to allow the short-circuit part 16 to be taken out.

Abstract: A socket-type terminal has an annular groove which is formed in a step portion between a base portion of a terminal connecting portion and a neck portion. A distal end of a lance head of a retaining lance for preventing withdrawal of the terminal is so formed as to fit in the groove. With this construction, when the terminal is pulled in a longitudinal direction, the whole of the retaining lance is displaced in a direction of the axis of the terminal. Therefore, the terminal is firmly retained in a housing without damaging the retaining lance.

Abstract: A miniaturized shunt connector assembly provides sufficient retention force between the assembly and mating contact posts and includes an insulative housing defining a contact-receiving cavity and a contact mounted therewithin. The contact includes an opposing pair of generally opposing support pieces including parallel arm supporting portions spaced a given dimension apart. Resilient contact arms extend from an upper edge of each arm supporting portion and are inwardly and downwardly formed to project beyond the lower edge thereof. An anchor portion extends from a lower portion of each support piece and connects to an adjacent portion of the other of the pair of support pieces. One resilient contact arm opposes a corresponding resilient contact arm inside respective arm supporting portions and maintains a spaced apart dimension smaller than the dimension of the parallel arm supporting portions.

Abstract: A connector housing has terminal receiving chambers for respectively receiving press-connecting terminals, and those portions of the partition walls disposed facing outer sides of crimp arms of the press-connecting terminals can be retracted from an initial position where those portions of the partition walls are disposed facing outer sides of the crimp, arms. During the press-connecting operation, those portions of the partition walls are retracted, and after the press-connecting operation is completed, those portions are returned to their initial position, thereby suitably isolating the press-connecting terminals from one another. Thus, even if the thickness of the partition walls is reduced, they will not be deformed during press-fitting of a wire, and the resulting inadequate deformation of crimp arms of the terminals is eliminated.
