Zero insertion force socket connector

摘要

A substantially rectangular socket connector for connecting a CPU to a mother board, comprises a base and cover mounted on the base and movable relative thereto between open and closed positions along a diagonal direction of the connector. The cover defines a number slots extending in a direction parallel to the diagonal direction. The base forms a number of teeth slidably received in the slots. A number of contacts are fixedly received in contact passages defined in the base for engaging with/disengaging from pins of the CPU inserted into the connector in response to a movement of the connector between the closed and open positions. The cover further forms at least a ridge in a corresponding slot to divide the corresponding slot into two recessed regions. The tooth extending into the corresponding slot is received in either of the two recessed regions when the connector is at either of the open and closed positions whereby the connector can be more securely located at these two positions.
