Abstract
A lever member of a lever assisted insertion device engages with a front frame of a shelf before a fully inserted position of a substrate unit to form a leverage fulcrum on the front frame. A force that an operator applies to the lever member is transmitted to the substrate unit via a point of application with respect to the fulcrum, thereby inserting the substrate unit up to the fully inserted position. A buffering device abuts against the front frame of the shelf within a depth range of a front panel of the substrate unit before an operation start position at which the lever member engages with the front frame of the shelf, to absorb impact of the substrate unit at the time of insertion.
Claims9
An insertional buffering structure of a substrate unit that alleviates impact of the substrate unit to a backboard at the time of insertion of the substrate unit, in a shelf-type electronic device including:
- the substrate unit having a first connector;
- and
- a shelf for housing the substrate unit freely insertably and removably, the shelf including the back board, and a second connector to which the first connector is connected on the backboard, wherein
- the insertional buffering structure comprises a lever assisted insertion device and a buffering device provided on the substrate unit,
- the lever assisted insertion device includes a lever member that engages with a front frame of the shelf before a fully inserted position of the substrate unit at which the first connector is connected to the second connector, to form a leverage fulcrum on the front frame, and the lever member is constituted such that a force that an operator applies to the lever member is transmitted to the substrate unit via a point of application with respect to the fulcrum, thereby inserting the substrate unit up to the fully inserted position, and
- the buffering device abuts against the front frame of the shelf within a depth range of the front panel of the substrate unit before an operation start position at which the lever member of the lever assisted insertion device engages with the front frame of the shelf, to absorb impact of the substrate unit at the time of insertion.

- and
- a shelf for housing the substrate unit freely insertably and removably, the shelf including the backboard, and a second connector to which the first connector is connected on the backboard, wherein
- the insertional buffering structure comprises a lever assisted insertion device and a control device provided on the substrate unit,
- the lever assisted insertion device includes a lever member that engages with a front frame of the shelf before a fully inserted position of the substrate unit at which the first connector is connected to the second connector, to form a leverage fulcrum on the front frame, and the lever member is constituted such that a force that an operator applies to the lever member is transmitted to the substrate unit via a point of application with respect to the fulcrum, thereby inserting the substrate unit up to the fully inserted position, and
- the control device changes over a first operating state in which the control device abuts against the front frame of the shelf before an operation start position at which the lever member of the lever assisted insertion device engages with the front frame of the shelf, to obstruct progress of the substrate unit ahead from the operation start position, and a second operating state in which progress ahead from the operation start position is allowed, depending on a predetermined control release operation performed by the operator.
A substrate unit to be inserted and installed in a substrate housing shelf of an electronic device, comprising:
- a printed board;
- a connector wiring connected to the printed board;
- a front panel provided on the printed board on a front face side of the shelf;
- a lever assisted insertion device including a lever member that engages with a front frame of the shelf before a fully inserted position at which the connector is connected to a connector on the shelf side, to form a leverage fulcrum on the front frame, in which the lever member is constituted such that a force that an operator applies to the lever member is transmitted to the front panel via a point of application with respect to the fulcrum, thereby inserting the substrate unit up to the fully inserted position, and
- a buffering device that abuts against the front frame of the shelf within a depth range of the front panel before an operation start position at which the lever member of the lever assisted insertion device engages with the front frame of the shelf, to absorb impact of the substrate unit at the time of insertion.
