Abstract
Abstract An electrical connector in which a contact is mounted in a contact cavity in the connector insulator from the front and is removed forwardly from the cavity. The contact is formed with a forwardly and outwardly extending spring retention tine that engages a rearwardly facing shoulder in the cavity to prevent forward movement of the contact in the cavity. The tine embodies a relatively deformable area so that upon application of a predetermined forwardly directed force on the contact, the tine will fold back on itself at said deformable area, thereby allowing the tine to pass under the rearwardly facing shoulder in the cavity. Thus, the contact may be removed from the contact cavity without the use of a tool. The invention is particularly adaptable to contacts having wire-wrap tails which are accurately held in position by a stabilizing plate at the rear of the connector insulator.
