Description

  The technology disclosed in the present application relates to an electronic device.

  Some electronic devices include a rack and a unit mounted on the rack. Some of such electronic devices include a power bus bar provided in the rack and a connector provided in the electronic device and connected to the power bus bar as a structure for supplying power to the unit (for example, Patent Document 1). In general, in such a power supply structure, if an error occurs between the position of the power bus bar and the position of the connector, the power bus bar and the connector may not be correctly connected.

  Therefore, a floating structure of a connector has been proposed in which a notch is provided in a panel that supports the connector, and the connector is slidably attached to the notch (see, for example, Patent Document 2). According to such a floating structure of the connector, even if an error occurs between the position of the power bus bar and the position of the connector, the error can be absorbed by sliding the connector, and the power bus bar and the connector can be connected correctly. Can be expected.

Inserted. In a state where the contact 92 is inserted to the back side of the connection groove 24, the contact 92 contacts the plurality of convex portions 29 formed on the bus bar contact 28. Further, in a state where the contact member 90 is connected to the power bus bar 20 in this way, the side surfaces of the pair of power bus bars 20 are held by the pair of side guides 73 and the power bus bar 20 and the connector 50 are fitted. It becomes a state.

(Second fitting example)
16A and 16B are diagrams illustrating a second fitting example in which the connector 50 in an oblique state is fitted to the power bus bar 20 shown in FIG. In the second fitting example, when the unit 12 is inserted into the rack 11 from the front side of the rack 11, the entire unit 12 including the connector 50 is in an oblique state, and with respect to the rack 11. It is shifted to the right.

  In this second fitting example, as shown in the state (1) to the state (2), when the unit 12 is inserted into the rack 11, the tapered portion 77 formed at the tip end portion of the guide protrusion 72 is formed. The taper portion 23 formed on the opening side of the guide groove 22 between the pair of power bus bars 20 comes into contact. As a result, the base member 30 together with the power bus bar 20 moves to the right with respect to the rack 11, and the entire connector 50 including the connector main body 70 moves to the left with respect to the unit 12.

  Further, as shown in the state (2) to the state (3), when the unit 12 is further inserted into the rack 11, the taper portion 100 formed at the tip of the right contact 92 becomes the right power bus bar. It contacts the inclined portion 25 formed on the opening side of the 20 connection grooves 24. As a result, as shown in the state (3), the entire contact member 90 including the right contact 92 rotates (tilts) to the left, and the right contact 92 is inserted into the connection groove 24 of the right power bus bar 20. The Further, the entire connector 50 including the connector main body 70 moves further to the left with respect to the unit 12.

Is movably supported. Therefore, since the three floating structures are adopted, it is possible to secure a relative movement amount of the contact member 90 with respect to the power bus bar 20. Thereby, even if an error occurs between the position of the power bus bar 20 and the position of the connector 50, this error can be effectively absorbed. As a result, the power bus bar 20 (the plurality of convex portions 29) and the contact member 90 can be brought into contact more uniformly.

  The power bus bar 20 is supported so as to be movable in the left-right direction of the rack 11 with respect to the rear portion of the rack 11, and the connector main body 70 is movable in the left-right direction and vertical direction of the unit 12 with respect to the rear portion of the unit 12. It is supported. Therefore, the connector main body 70 can be slid vertically and horizontally with respect to the power bus bar 20, so that the position of the connector 50 can be appropriately adjusted with respect to the power bus bar 20.

  In addition, the contact member 90 is supported so as to be movable in the left-right direction, the up-down direction, and the front-rear direction of the unit 12 with respect to the connector main body 70, and the entire contact member 90 including the contact 92 rotates up and down, left and right ( (Tilting) is possible. Therefore, even when the position of the connector 50 is displaced with respect to the power bus bar 20, the entire contact member 90 including the contact 92 rotates vertically and horizontally so that the contact 92 is smoothly inserted into the connection groove 24 of the power bus bar 20. Can be inserted.

  Further, even when the unit 12 is mounted obliquely on the rack 11, the contact 92 can be inserted straight into the connection groove 24 of the power bus bar 20 by rotating the contact member 90. Thereby, even if the unit 12 is mounted on the rack 11 at an angle, the contact between the power bus bar 20 and the contact member 90 can be made uniform.

  Next, a modification of this embodiment will be described.

  In the above embodiment, the power bus bar 20 is supported by the rack 11 via the base member 30 and the mounting bracket 40. However, the power bus bar 20 may be supported by the rack 11 via a member other than the base member 30 and the mounting bracket 40.

  In the above embodiment, the long hole 32, the screw 44, and the spacer 45 are used as a structure for supporting the power bus bar 20 movably in the left-right direction of the rack 11 with respect to the rear portion of the rack 11. The structure may be used.

  Moreover, in the said embodiment, although the screw 44 and the spacer 45 are used as an example of the "bus-bar support member" inserted in the long hole 32, members other than the screw 44 and the spacer 45, such as a pin, are used, for example. May be.

  In the above embodiment, the connector support hole 63, the screw 79, and the spacer 80 are used as a structure that supports the connector main body 70 movably in the horizontal direction and vertical direction of the unit 12 with respect to the rear portion of the unit 12. However, other structures may be used.

  Moreover, in the said embodiment, although the screw 79 and the spacer 80 are used as an example of the "connector support member" inserted in the connector support hole 63, members other than the screw 79 and the spacer 80, such as a pin, are used, for example. May be used.

  In the above-described embodiment, the contact support hole 96 and the screw 101 are used as a structure that supports the contact member 90 movably in the left-right direction, the vertical direction, and the front-rear direction of the unit 12 with respect to the connector main body 70. However, other structures may be used.

  In the above embodiment, the screw 101 is used as an example of a “contact support member” inserted into the contact support hole 96. However, a spacer in addition to the screw 101 may be used as an example of the “contact support member”, similarly to the support structure of the power bus bar 20 to the rack 11 and the support structure of the connector main body 70 to the unit 12 described above. . Further, as an example of the “contact support member”, for example, a member other than the screw 101 such as a pin may be used.

  In the above-described embodiment, the connector 50 has a convex plug shape, but may have a concave receptacle shape. When the connector 50 has a concave receptacle shape, the power bus bar 20 may have a convex plug shape.

  In the above embodiment, as shown in FIG. 3, the power supply device 16 is mounted on the rack 11, and the power bus bar 20 is supplied with power from the power supply device 16. However, the power supply to the power bus bar 20 may have other structures.

  Here, FIG. 17 is a diagram showing a modification of the power supply system to the power bus bar 20 shown in FIG. In the modification shown in FIG. 17, the power bus bar 20 is supplied with power from the system power supply. Thus, either the power supply device or the system power supply may be used to supply power to the power bus bar 20.

  As mentioned above, although one embodiment of the technique disclosed in the present application has been described, the technique disclosed in the present application is not limited to the above, and various modifications may be made without departing from the spirit of the present invention. Of course, it is possible.

  In addition, the following additional remark is disclosed regarding one Embodiment of the technique which the above-mentioned this application discloses.
