Abstract: An insert retention device for retention of same in a dielectric housing serving as a screwlock especially suitable for high speed connector assemblies; these insert retention devices are desirable because of their characteristics when cold pressed into a plastic housing and are useful for electronic printed circuit board assembly and the like.

Abstract: An electrical connector comprises a dielectric housing having terminal passages in which electrical terminals are secured. A metal shell is secured onto the housing and ground contact means is provided for achieving electrical contact with the metal shell and a ground plate on a circuit board, the ground contact means including spring means for urging contact members of the ground contact means into electrical engagement with the ground plate.

Abstract: This connection construction for an electronic component includes a circuit board, a circuit pattern on the circuit board, an external connection terminal mounted to the circuit board and connected to the circuit pattern, a ground electrode opposing the external connection terminal, and a mass of dielectric material interposed between the ground electrode and the external connection terminal. Thereby proper connection is obtained for the circuit board, without introducing any undesirable delay, or deterioration or degradation of output signal therefrom. Thus, a connection construction for an electronic component is obtained which is particularly suitable for handling high speed signals.

Abstract: This invention relates to a connector for coupling a printed circuit board to an outside circuit and includes means to clamp said connector to said circuit board to form a sturdy circuit element that can be tested for conductivity without requiring spot soldering in the clamped portions. The connector may be readily disconnected from the printed circuit board should the test fail and another printed circuit board readily substituted. The connector, with the printed circuit board clamped thereto, is maintained in clamped relation for further assembly with other assembly elements should the test be passed.

Abstract: An electrical jack module comprising a vertically stacked series of electrical jacks having respective housings provided with respective open-ended axial bores wherein an electrical jack plug may be inserted for interference engagement with a protruding portion of a moveable contact member biased resiliently into electrical engagement with a fixed contact member disposed in grooves in the longitudinal side surfaces of the housings. A pair of the fixed contact members comprise integral end portions of a pre-shaped shunt wire press-fitted into plurality of communicating grooves provided in aligned side surfaces of adjacent housings in the vertically stacked series. The moveable contact members are integrally connected through respective preshaped spring wires disposed in grooves in the sides surfaces of the housing to respective wire terminals protruding in a common array from a proximal supporting surface of the vertically stacked series of housings.

Abstract: A cross-shaped retainer post with an oval longitudinal base which may break through when the ribs of the cross are stressed upon insertion into a locating hole.

Abstract: A method and quick disconnect contact for mounting on a pre-drilled circuit board is disclosed. The generally flat contact is provided with two stabilizing portions between the mounting legs. The stabilizing portions form pivot or pressure points spaced from or offset from associated major surfaces of the contact to minimize deformation and likelihood of breakage of the mounting legs upon application of external forces.

Abstract: An apparatus for interconnecting functional component circuits and branch circuits of a wiring harness. A wiring board includes a plurality of tab contact members and mounted on one surface of the wiring board is a first printed-circuit board including a plurality of control element components forming functional component circuits. Also mounted on the other surface of the wiring board is a second printed-circuit board which includes the functional element components of the components forming the functional component circuits.

Abstract: A holder for a shielded cable electrical connector used to connect the electrical connector to a printed circuit board includes a pair of opposed flange members for gripping the connector, a pair of opposed finger members extending from the tail portion of the holder for clamping the end of the cable providing a strain relief for the cable, a first surface portion extending from the surface of the holder in a direction to hold the connector within the flange members, a second surface portion of the holder which extends in a direction to engage a ground member located on the top surface of the printed circuit board upon mounting of the holder to the circuit board and a pair of tab portions for engaging the edge of the printed circuit board to lock the holder and the connector into engagement with a like connector mounted on the printed circuit board.

Abstract: A backplane wiring comprising a backplane printed circuit board 1 through which contact pins 2 are inserted and centering strips 3 which can be plugged on the contact pins of the circuit board to allow the acceptance of plugs or clip connectors so as to provide as many plugs as possible for the backplane wiring of the PC cards. The backplane printed circuit board 1 comprises a complete pin field and the centering strips 3 are provided with lateral recesses 4 at their longitudinal walls for accepting adjoining contact pins 2.

Abstract: An electrical power connector for conducting electrical power from a power bus bar to a circuit card. More particularly, the connector includes contact elements having tab terminal receiving receptacles positioned in a dielectric housing in a staggered arrangement so that the forces requires to insert tab terminals into the receptacles are distributed. Further, the terminal-receiving space in each receptacle is defined by a stationary member on one side and dual side-by-side spring-biased members on the other side so that the force required to insert a tab terminal therein is initially incremental.
