Abstract: An apparatus having a backplane adapted for coaction with a number of circuit boards arranged in side-by-side relationship and including a number of mutually adjacent and mutually spaced elongated, narrow backplane-related connector fields, each of which is adapted for firm but easily removed mechanical and electrical coaction with a corresponding connector field related to an edge-part of respective circuit boards. A number of first selected backplane-related connector fields are connected electrically to a first bus, and a number of second selected backplane related connector fields are connected electrically to a second bus. The backplane-related connector fields are divided into a predetermined number of groups wherein each group is allotted a part-section of the backplane and wherein the first connector fields of respective groups are joined together and connect to the first bus.

Abstract: A panel mounted electrical connector is adapted for mounting in an aperture in a panel. The connector includes a dielectric housing insertable along an axis through the aperture from a first surface to at least a second surface of the panel and including at least one side wall. A flexible latch arm projects from the side wall and includes a locking portion adapted to engage the second surface of the panel at the periphery of the aperture when the housing is inserted completely therethrough. A stop bar projects transversely outwardly of the side wall and includes a stop shoulder adapted to engage the first surface of the panel at the periphery of the aperture when the housing is inserted therethrough. A yieldable anti-vibration arm projects inwardly of the stop bar and is axially aligned with the flexible latch arm.

Abstract: An electrical connector is provided with at least two pairs of signal-carrying contacts, which provides a low cost, compact, and rugged construction for minimizing crosstalk. While two initial contacts (A, B, FIG. 2) of the two pairs (102, 104) lie adjacent to each other, so there is unwanted capacitive and inductive coupling between them, secondary contacts (C, D) of the two pairs do not lie adjacent to the initial contacts and therefore are not as closely coupled to the initial contacts. Each secondary contact is capacitively coupled to an initial contact of the other pair by a lateral extension (110, 122) formed in one of the contacts which overlies the other contact in a local region (120) of limited length. The capacitive coupling resulting from the lateral extensions substantially cancels crosstalk that otherwise would exist.

Abstract: The present invention relates to a tethered protective cover which is detachably mounted to a multi-pin electrical connector. Specifically, the cover is mounted to a diagnostic connector located under the instrument panel of an automobile. The cover includes a shroud which is mountable to the connector. The shroud includes opposite side walls and an intermediate wall extending therebetween. The shroud has a size and shape such that clearances are created between each shroud side wall and the connector. The shroud is formed using a resilient material such that when the opposite side walls are squeezed inwardly, the clearances are reduced, causing the intermediate wall to gap outwardly from the connector. A latch button on the intermediate shroud wall interacts with a projection on the connector to secure the shroud to the connector.

Abstract: Three male terminals are inserted respectively into terminal receiving chambers in a male connector housing and a bus bar is inserted into the terminal receiving chambers through a through-hole. As a result, the insertion side portion of the bus bar is press-fitted in reception grooves in bus bar press-fitting portions disposed beneath the through-hole. Thus, the insertion side portion of the bus bar is received in the reception grooves in the three male terminals, and is mechanically fixed to and electrically connected to the male terminals, so that three insulated wires connected respectively to the male terminals are connected together only at the male connector housing.
