Connection part and method for producing a connection part
View Patent ↗A connection part has a plastic body ( 1 ) and at least one electrical connection element ( 4, 5 ) having a fixing region ( 4 a, 5 a ) which is injection molded into the plastic body ( 1 ), and having a connection lug ( 4 b, 5 b ) which has a cutout ( 12, 13 ) for a screw connecting element. A corresponding connecting element ( 8, 9 ) can be introduced into a receiving area ( 2, 3 ) beneath the connection lug ( 4 b, 5 b ). At least one latching element ( 10, 11; 14, 15 ) holds the corresponding connecting element ( 8, 9 ) in the receiving area ( 2, 3 ) such that it cannot fall out once it has been inserted. A connection part is thus created which has a securely and permanently fixed connection element with cost-effective production and, at the same time, makes it possible to compensate for the tolerance with respect to a contact element to be mounted externally.
1. A connection part comprising:
a plastic body,
at least one electrical connection element,
a fixing region which is injection molded into the plastic body,
a connection lug which has a cutout for a screw connecting element,
a corresponding connecting element,
a receiving area beneath the connection lug into which the corresponding connecting element can be inserted in a insertion direction from outside and which receives said corresponding connecting element, and
two lateral latching hooks designed to spring open laterally in a direction perpendicular to the insertion direction which hold the corresponding connecting element in the receiving area such that it cannot fall out once it has been inserted but wherein it can move within the receiving area sufficiently to adapt to a longitudinal axis of the screw connecting element.
2. A connection part according to claim 1 , wherein the corresponding connecting element is a square nut.
3. A connection part according to claim 2 , wherein the square nut has front and bottom walls and sidewalls perpendicular to the front and bottom walls.
4. A method for producing a connection part, comprising the steps of:
injection molding into a plastic body a fixing region of a connection element having a connection lug suitable for receiving a screw connecting element,
introducing a connecting element which corresponds to an external screw connecting element from the outside in a insertion direction into a receiving area, delimited by the plastic body, beneath the connection lug, and
providing on the plastic body two lateral latching hooks designed to spring open laterally in a direction perpendicular to the insertion direction which holds the corresponding connecting element in the receiving area such that it cannot fall out once it has been inserted but wherein it can move sufficiently to adapt to a longitudinal axis of the screw connecting element.
5. A method according to claim 4 , wherein the corresponding connecting element is a square nut.
6. A method according to claim 5 , wherein the square nut has front and bottom walls and sidewalls perpendicular to the front and bottom walls.
7. A connection part comprising:
a plastic body with an injection molded fixing region,
at least one electrical connection element,
a connection lug which has a cutout for a screw connecting element,
a receiving area beneath the connection lug into which a nut can be introduced in a insertion direction from outside and which receives said nut, and
two lateral latching hooks designed to spring open laterally in a direction perpendicular to the insertion direction which holds the nut in the receiving area such that it cannot fall out once it has been inserted but wherein it can move sufficiently to adapt to a longitudinal axis of the screw connecting element.
8. A connection part according to claim 7 , wherein the nut has a square form.
9. A connection part according to claim 8 , wherein the square nut has front and bottom walls and sidewalls perpendicular to the front and bottom walls.
