Contact for plug connection with primary locking lance and positioning spring arrangement

Abstract

Contact (10) which is provided for locking in a contact chamber (16) of a plug connection element (1), wherein the contact (10) comprises: a contact box (13); and a primary locking lance (14) resiliently protruding from a first side surface (18) of the contact box (13) in a first direction (22); characterized in that the contact (10) further comprises a spring arrangement (21) which resiliently protrudes from a second side surface (19) of the contact box (13) in a second direction (23) opposite the first direction (22) and which has a smaller spring constant than the primary locking lance (14), wherein the spring arrangement (21) comprises at least two partial spring arrangements (30, 31), wherein one partial spring arrangement (30) is arranged in front of the primary locking lance (14) in the longitudinal direction of the contact box (13) and one partial spring arrangement (31) is arranged behind the primary locking lance (14) in the longitudinal direction of the contact box (13).

Claims

[1] Contact (10) which is provided for locking in a contact chamber (16) of a plug connection element (1), the contact (10) comprising: a contact box (13); and a primary locking lance (14) resiliently projecting from a first side surface (18) of the contact box (13) in a first direction (22); characterized by , that the contact (10) further comprises a spring arrangement (21) which projects resiliently from a second side surface (19) of the contact box (13) in a second direction (23) opposite to the first direction (22) and which has a smaller spring constant than the primary locking lance (14), wherein the spring arrangement (21) has at least two partial spring arrangements (30, 31), wherein one partial spring arrangement (30) is arranged in the longitudinal direction of the contact box (13) in front of the primary locking lance (14) and one partial spring arrangement (31) is arranged in the longitudinal direction of the contact box (13) behind the primary locking lance (14). [2] Contact according to claim 1, wherein a projection height (d2) of the spring arrangement (21) is greater than the sum of a manufacturing tolerance of the contact (10) and a manufacturing tolerance of the contact chamber (16). [3] Contact according to claim 1 or 2, wherein a projection height (d2) of the spring arrangement (21) is smaller than a projection height (d1) of the primary locking lance (14). [4] Contact according to one of claims 1 to 3, wherein a projection height (d2) of the spring arrangement (21) is less than 0.2 mm. [5] Contact according to one of claims 1 to 4, wherein the spring arrangement (21) is formed integrally with the contact box (13). [6] Contact according to one of claims 1 to 5, wherein the spring arrangement (21) is cut out of a wall of the contact box (13) forming the second side surface (19). [7] Contact according to one of claims 1 to 6, wherein both ends (27, 29) of the spring arrangement (21) are arranged flush with the second side surface (19). [8] Contact according to one of claims 1 to 7, wherein the second side surface (19) is opposite the first side surface (18) and is arranged parallel thereto. [9] Plug connection element (1) with at least one contact chamber (16) and at least one contact (10) latched into a contact chamber (16) by means of a primary locking lance (14) according to one of claims 1 to 8.
