Abstract
A coupling for connecting model cars of a model train includes an integrated resilient contact supported by a first coupling member disposed against a mating electrical connector of a second coupling member. The first and second coupling members are configured to bear mechanical tension and compression, while permitting vertical movement of one coupling relative to the other. The resilient contact and mating contact are configured to maintain an electrical connection during relative vertical movement of the coupling members. Using the coupling, separate cars of a model train may be placed in electrical communication with one another without requiring a separate electrical connector. A wireless connection may also be made through the coupling.
Claims19
A connector to be used in a model train, comprising:
- a first coupling member having a distal portion configured to attach to a first model train car;
- a second coupling member having a distal portion configured to attach to a second model train car, and a proximal portion configured to engage with a proximal portion of the first coupling member;
- and
- a resilient electrical contact associated with the second coupling member and disposed to make an electrical connection to a first electrical contact of the first coupling member when the proximal portion of the second coupling member is engaged with the proximal portion of the first coupling member.
