Docking system having elastic rail portions

A docking system for facilitating a connection of an electronics module to a mating connector, the docking system comprising:

• first and second rails that are separated from and oppose each other, each of the first and second rails having an elongated guide slot, each of the elongated guide slots receiving a corresponding guide portion of the electronics module during a sliding movement of the electronics module toward the mating connector, each of the elongated guide slots of the first and second rails are U-shaped and defined by two opposing walls and a connecting wall between the two opposing walls;
• a first elastic structure formed as part of one of the opposing walls of the first rail and separated from the connecting wall by a slot in the one of the opposing walls such that the first elastic structure has two first fixed ends and a first curved middle region between the two first fixed ends, the first elastic structure being a thin member such that the first curved middle region has first upper and lower curved surfaces that are curved downwardly toward the elongated guide slot to form a bow shape for the first elastic structure, the first lower curved surface defining a first engagement portion extending into the elongated guide slot of the first rail;
• and
• a second elastic structure formed as part of one of the opposing walls of the second rail and separated from the connecting wall by a slot in the one of the opposing walls such that the second elastic structure has two second fixed ends and a second curved middle region between the two second fixed ends, the second elastic structure being a thin member such that the second curved middle region has second upper and lower curved surfaces that are curved downwardly toward the elongated guide slot to form a bow shape for the second elastic structure, the second lower curved surface defining a second engagement portion extending into the elongated guide slot of the second rail;
• wherein the first engagement portion of the first elastic structure and the second engagement portion of the second elastic structure are configured to engage the guide portions of the electronics module, the first engagement portion and the second engagement portion being further configured to urge the guide portions against the other ones of the two opposing walls of the guide slots and to resist movement of the guide portions in a direction generally perpendicular to the sliding movement of the electronics module.
