Design for reduced connector pitch, with robust electromagnetic compatibility and strain relief abilities.
Disclosed is a device for securing surface mount connectors to a peripheral component interconnect (PCI) tailstock while minimizing pitch.
Maximizing data I/O from a computer card, while minimizing electromagnetic compatibility (EMC) exposures, and providing reliable connections, are all assets for card designs. Often surface mount (SMT) connectors are used on cards to improve data rate. But, an SMT connector is more prone to failure from cable induced stresses, as compared to pin thru connectors, if there is not additional mechanical support to the board (besides the SMT leads).
The figure shows a clamp that mechanically limits strain to a connector. The front facing screws are staggered vertically so that the connectors can nest closer together horizontally. This design also symmetrically compresses the gasket, while providing strain relief to the connector, and staying within the PCI form factor requirements.
Generally, connector mechanical attachments to tailstocks consist of two screws on the centerline of the connector, which limits how closely the connectors can be placed together on a card. By applying the concept of staggered screws to the clamp attachment, all the requirements of the PCI spec, mechanical strain relief on the card, and EMC gasket compression can be met. The staggered screw design can be part of the connector itself, or part of a sep...
