Abstract
The receptacle contact (10) includes a box-shaped contact section (12) with its upper wall folded over to provide protrusions (36) to abut against the tip of a resilient arm (48). Such receptacle contacts (10) are inserted into contact receiving cavities (42) in the connector housing (44). A double-lock member (150) may be used for double locking the contacts.
Claims18
An electrical connector assembly comprising:
- an insulated housing member with a plurality of contact receiving cavities therein, at least one of said cavities includes a resilient arm which is formed on a wall of said at least one cavity,
- an electrical contact for insertion into said at least one cavity, said contact having a general box shape with an upper wall portion, said upper wall portion having an upwardly extending projection for sliding engagement with said resilient arm and contact with an end surface of said resilient arm;
- and a double lock member for retaining said contact in said housing;
- whereby, when said contact is inserted into said at least one cavity said projection engages and deflects said resilient arm for an initial low insertion force, and as the contact is inserted further the insertion force increases as a portion of said resilient arm engages said cavity wall, and when said contact is fully inserted said projection contacts the end surface of said resilient arm thereby retaining said contact in said at least one cavity against separation forces.

An electrical connector assembly comprising:
- an insulated housing member with a plurality of contact receiving cavities therein, at least one of said cavities includes a resilient arm which is formed on a wall of said at least one cavity,
- an electrical contact for insertion into said at least one cavity, said contact having a general box shape with an upper wall portion, said upper wall portion having an upwardly extending thickened projection centrally of said upper wall portion for sliding engagement with said resilient arm and engagement with an end surface of said resilient arm thereby retaining said electrical contact within said at least one cavity,
- and a double lock member for retaining said contact in said housing.
An electrical connector assembly comprising:
- an insulated housing member with a plurality of contact receiving cavities therein, at least one of said cavities includes a resilient arm which is formed on a wall of said at least one cavity;
- an electrical contact for insertion into said at least one cavity, said contact having an upper portion, said upper portion includes a thickened projection centrally of said upper portion for sliding engagement with said resilient arm and engagement with an end surface of the resilient arm thereby retaining said electrical contact within said at least one cavity,
- a double lock member for retaining said contact in said housing;
- and
- said contact includes a wire termination portion having a double-lock barrel member for engaging the double-lock member.
2 more elements
An electrical connector comprising:
- an insulated housing having a contact-receiving cavity;
- a resilient arm provided by a wall of said contact-receiving cavity extending downwardly from the wall and toward a front end of said housing;
- an electrical contact insertable into said contact-receiving cavity and including a contact section and a wire-connection section;
- and
- an upper portion of said contact section adjacent an inner end of said contact section being folded over thereby forming a protrusion extending above a surface of said upper portion;
- whereby said protrusion is engaged by an engaging surface of said resilient arm when the electrical contact is fully inserted into said contact-receiving cavity thereby retaining said electrical contact therein.
