Back plug-in connector device
View Patent ↗A back plug-in connector device having a floating structure, comprises: a body chassis, a cover and a support plate on which a connector is mounted. The support plate is sandwiched by the body chassis and the cover so as to constitute the floating structure.
1. A back plug-in connector device having a floating structure, comprising:
a body chassis, a cover, a support plate on which a connector is mounted and a sub-board, wherein:
the connector is mounted on the sub-board and the sub-board is attached on the support plate,
the support plate is sandwiched by the body chassis and the cover so as to constitute the floating structure,
the support plate comprises one or more guide pins on an edge surface portion of the support plate, the body chassis comprises one or more groove portions, each of the groove portions engaging a respective of the one or more guide pins with a clearance allowing the guide pin to float in the groove portion, and the one or more guide pins are cylinder-shaped.
2. The connector device as defined in claim 1 , wherein an end portion of the cylinder-shaped one or more guide pins are sphere-shaped or semi-sphere-shaped.
3. The connector device as defined in claim 1 , wherein at least one of the one or more guide pins which engages a respective of the one or more groove portions is provided on each edge surface of the edge surface portion of the support plate.
4. The connector device as defined in claim 1 , wherein a concave-shaped guide receiving portion for positioning at plug-in is provided on the support plate such that the guide receiving portion engages a convex-shaped guide member provided on a backboard of a cabinet side.
5. The connector device as defined in claim 1 , wherein the floating structure is constituted such that the support plate having the one or more guide pins is fitted into the body chassis having the one or more groove portions and that the cover is fixed to the body chassis from a same direction as the support plate so as to sandwich the support plate.
6. The connector device as defined in claim 5 , wherein an end portion of the cylinder-shaped one or more guide pins are sphere-shaped or semi-sphere-shaped.
7. The connector device as defined in claim 5 , wherein at least one of the one or more guide pins which engages a respective of the one or more groove portions is provided on each edge surface of the edge surface portion of the support plate.
8. The connector device as defined in claim 5 , wherein a concave-shaped guide receiving portion for positioning at plug-in is provided on the support plate such that the guide receiving portion engages a convex-shaped guide member provided on a backboard of a cabinet side.
