Description

  The present invention relates to a backboard connection structure, and more particularly to a backboard connection structure for connecting panels having various electrical functions provided on the back side of an electric device.

  Conventionally, a backboard as a printed board is mounted on the back side of the electric device in order to connect a panel having various electric functions. In some cases, such a board is attached not to the back side but to the front side of the electric device. Here, when the electrical device is large, it is ideal to connect all the panels with a single backboard. However, in reality, there is a limit to the size of the backboard that can be manufactured. A backboard divided into more than one is often used. In such a case, it is necessary to electrically connect the backboards.

  FIG. 7 shows a conventional example of a structure in which backboards 73A and 73B divided into two pieces are electrically connected. As shown in FIG. 7, two pieces of panels 71A and 71B are connected to each other. The backboards 73A and 73B are directly connected via connectors 76A and 76B (see Patent Document 1).

JP 2001-189581 A

  However, in the conventional backboard connection structure described in Patent Document 1 and the like, after the two backboards 73A and 73B are connected by the connectors 76A and 76B, the two connected backboards 73A and 73B are connected to the device. There was a problem that workability was poor because it was necessary to attach to the. Further, since the connectors 76A and 76B can only be attached to one side of the backboards 73A and 73B, there is a problem that the number of connectable backboards 73A and 73B is greatly limited.

  Therefore, the present invention has been made in view of the problems in the above-described conventional backboard connection structure, has good workability, has a small restriction on the number of connectable backboards, and secures a larger number of connections. An object of the present invention is to provide a backboard connection structure that can cope with high density.

  In order to achieve the above object, the present invention provides a backboard connection structure, which is a connector that can be attached and detached by moving adjacent backboards in a direction perpendicular to the respective panel mounting surfaces of the adjacent backboards. It is characterized by connecting via.

  According to the present invention, in order to connect adjacent backboards using a connector that is detached by moving in a direction perpendicular to the panel mounting surface, both the adjacent backboards are fixed to the apparatus, The backboard can be connected with a connector. As a result, it is not necessary to fix the entire backboard to the apparatus after connecting adjacent backboards with a connector as in the prior art, and the workability is greatly improved.

  In the backboard connection structure, there may be three or more backboards. Even if there are three or more backboards, the backboards can be easily connected via connectors that are detached by moving in the vertical direction with respect to the panel mounting surfaces of the adjacent backboards.

  In the backboard connection structure, each of the connectors provided on each of the adjacent backboards may be connected via a printed board, and the adjacent backboard may be connected via one printed board. When connecting, a plurality of connectors provided on each backboard and a plurality of connectors provided on the printed board may be used. As a result, even if the number of wires increases, the density of the printed board can be increased or the number of connections can be increased.

  As described above, according to the present invention, the workability is good, the restriction on the number of backboards that can be connected is small, a larger number of connected boards can be secured, and the back that can cope with higher density. A board connection structure can be provided.

  FIG. 1 shows a first embodiment of a backboard connection structure according to the present invention. This backboard connection structure is composed of two backboards 3 for connecting two panels 1 (1A, 1B). In order to connect (3A, 3B) to each other, a connector 5 (5A, 5B) provided on each of the back boards 3A, 3B and a printed board 4 are provided.

  The backboards 3A and 3B are printed boards that are installed on the back surface of an electric device (not shown) and have a function of electrically connecting the panels 1A and 1B having individual functions mounted in the device.

  As shown in FIG. 2, the printed board 4 for connecting the backboards 3A and 3B to each other is made of a conductor such as copper on the surface of the plate-like insulator 4a formed of glass fiber reinforced epoxy resin or the like. The circuit pattern 4b formed in the above is provided, and electrical connection is made between electrical components and between panels.

  As shown in FIG. 3, the connector 5 (5A, 5B) has a plug-side electrode 5aa made of a conductor formed by performing a surface treatment such as gold plating or nickel plating on copper, brass or the like from an insulator such as a resin. A plug-side connector 5a fixed by a plug-side housing 5ab; a socket-side electrode 5ba made of a conductor formed by subjecting copper, brass or the like to gold plating or nickel plating; and a socket made of an insulator such as a resin. By connecting the socket side connector 5b fixed by the side housing 5bb, electrical connection and mechanical holding are realized. The connector 2 shown in FIG. 1 is also configured in the same manner as the connector 5 although the dimensions are different. Note that the configurations of the printed board 4 shown in FIG. 2 and the connector 5 shown in FIG. 3 are merely examples, and may be of different types as long as they have similar functions.
