PCB connector having a conductive base body having a spring body and a put-through body
The invention relates to a PCB connector for fastening a first printed circuit board on a second printed circuit board. The PCB connector may have a longitudinal base body with a clamping and fastening device for tool-free fastening of the PCB connector on a printed circuit board. The clamping and fastening device has a put-through body and a spring body which is formed extendable upon putting-through the put-through body through the land. The base body is thus pressed against the printed circuit board by the spring body.
1. PCB connector for fastening a first printed circuit board on a second printed circuit board and for providing an electrically conductive connection between the two printed circuit boards, the PCB connector comprising:
a longitudinal electrically conductive base body having at least at a first end a clamping and fastening device for tool-free fastening of the PCB connector at one of the printed circuit boards in a land, and
a spring body is provided wherein:
at the first end of the base body a put-through body for putting through the land of the printed circuit board is formed, wherein the base body and the put-through body are formed integrally,
the base body and the put-through body form a stop for defining a put-through depth of the put-through body through the land,
the spring body is configured to be expandable upon and/or after putting the put-through body through the land, wherein the base body is pressed by the spring body against the printed circuit board,
the put-through body and the spring body at least partially form the clamping and fastening device, and
a shoulder is formed at a first end portion at the spring body for defining a penetration depth of the spring body in the land.
2. PCB connector according to claim 1 , wherein the spring body is formed sleeve-like.
3. PCB connector according to claim 1 , wherein the spring body has an outer diameter that substantially corresponds to the inner diameter of the land.
4. PCB connector according to claim 1 , wherein a second end portion of the spring body is formed to be bent towards a central axis of the spring body.
5. PCB connector according to claim 1 , wherein the put-through body comprises a snap-in device for a second end portion of the spring body at its end portion facing away from the base body.
6. PCB connector according to claim 1 , wherein the put-through body has a widening at its end portion facing away from the base body.
7. PCB connector according to claim 1 , wherein the spring body is formed integrated in the put-through body.
8. PCB connector according to claim 1 , wherein the spring body is formed compressible and the spring body has a diameter in an unloaded state that is larger than a diameter of the land.
9. PCB connector according to claim 1 , wherein a clamping and fastening device is formed at each of a first end and a second end of the base.
