Abstract
A contact spring contained in a conforming recess in a guide channel has a U-shaped portion with projecting side tabs embracing the edge of a circuit board. The side tabs rest against conductors on the circuit board which carry circuit board potentials and establish a good electrical connection between the conductors and the contact spring. The contact spring also grips the circuit board. A spring leg on the contact strip goes through an opening in the guide channel and engages the subassembly carrier.
Claims3
A connector for removably mounting a circuit board on a subassembly carrier, the circuit board carrying electronic components and comprising at least one conductor run, the subassembly carrier comprising a conducting surface at ground potential, the connector providing a low resistance connection between the conductor run and the conducting surface of the carrier, the connector comprising:
- a guide member comprising a channel for receiving the circuit board, a recess in the channel, a base wider than the channel, and an opening extending from the channel to the base, the opening wider than the channel;
- a U-shaped contact conformably fitted in the recess, the contact comprising resilient side portions adapted to positively engage the circuit board on both sides and to make a highly conductive electrical connection to the conductor run;
- and
- a spring leg on the contact, the spring leg adapted for passage through the opening in the guide member, the spring leg wider than the channel and comprising a surface adapted to conformably engage the conducting surface of the subassembly carrier to make a highly conductive electrical connection thereto.
