Coaxial connector

A connector has upper and lower rows of contacts (20, 22, FIG. 4 ) whose contact tails (40, 42) are soldered to front and rear rows of pads (26, 24) on a circuit board (14), which provides flexibility in downward deflection of all contact tails in a short forward-rearward distance (B) . While the upper tails of the upper row of contacts extend at a downward-forward incline, the lower tails have rear portions (80) with inclined parts (90) that extend at an upward-forward incline, and forward portions (82) with inclined parts (92) that extend at downward-forward inclines. A heating bar (102, FIG. 7 ) for heating the forward ends (120, 122) of the contact tails for reflow soldering to the pads, has slots (124) in its lower surface (106) that extend from its rear end (126) to a location (130) behind its front end (132).

Termination of contact tails to PC board

A drawer connector is provided with modular components to facilitate the replacement of those portions of the drawer connector that are subject to the greatest wear. The drawer connector comprises mateable female and male panel mount drawer connector housings having mateable terminals press fit or otherwise lockingly engaged therein. The conductive leads are not permanently terminated to the terminals of the drawer connector. Rather, the conductive leads are terminated to modular connector terminals or terminal assemblies which in turn are lockingly but releasably mounted to the respective rear sides of the panel mount assemblies of the drawer connector. Thus, the panel mount assemblies can be discarded and replaced upon the damage of the frequently connected and disconnected terminals therein, while still retaining the time and labor intensive termination work on the conductive leads. Alignment of the drawer connector housings is facilitated by a frangible float collar formed unitarily with at least one of the housings. The float collar is severed from the remainder of the housing as the housing is connected to the panel. However, the size and relative disposition of the float collar relative to the remainder of the housing permits a controlled floating therebetween.

A floating panel mount for an electrical connector comprises opposed pairs of multiple cantilevered latch structures. Each latch structure comprises a lower arm cantilevered from a mounting flange. An upper arm is cantilevered from the end of the lower arm remote from the mounting flange, and is angularly aligned thereto. A locking arm is cantilevered from the end of the upper arm remote from the lower arm such that the lower arm and the locking arm extend angularly from opposed ends of the upper arm and from opposite sides thereof. The maximum cross-sectional dimension defined by the upper and locking arms exceeds the maximum cross-sectional dimension of a mounting aperture in a panel. However, the cross-sectional dimensions defined by the upper arms is substantially less than the cross-sectional dimensions of the mounting aperture. The arms can be deflected to enale the latch structures to pass through the mounting aperture. Thereafter, the latch structures will return to their unbiased, undeflected condition such that the panel is engaged intermediate the locking arms and the mounting flange. However, the smaller cross-sectional dimensions of the upper arms enables float relative to the panel.

Electrical connectors are slidably received in side-by-side serial array in elongated, hollow tubular cassettes. The cassettes are shaped to receive the connectors only in a single orientation, and protect terminals which partly extend from the connector housings in an intermediate assembly stage. Cassettes are vertically stacked in a feed system, and when the bottom cassette is emptied of connectors, it is released from the stack and replaced with a full cassette.
