Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed circuit board housing in which a plurality of printed circuit boards are held in a board housing case.

2. Description of the Related Art Conventionally, in this type of device, a large number of printed circuit board guides are provided in parallel on the upper and lower inner surfaces of a rectangular parallelepiped-shaped board storage case, a number of connectors are attached to the inner wall of the inner wall, and the printed circuit boards are guided by the guides. It is assembled by inserting the printed circuit board side connector into the housing case side connector. At this time, the connector of each printed circuit board has a connection terminal arrangement unique to each printed circuit board, so that the connector on the side of the storage case naturally corresponds to each printed circuit board. These connectors are fixed at predetermined positions with respect to the storage case, so that the insertion position of the printed circuit board in the storage case is predetermined.

By the way, in such a printed circuit board housing, it is necessary to adjust the printed circuit board, and in that case, it is necessary to place the printed circuit board to be adjusted in a reachable position while being connected to the connector. However, in the conventional structure, many printed circuit boards are arranged in parallel inside the storage case, so even if the side wall of the storage case is cut out, the printed circuit board sandwiched on both sides is close to the printed circuit board. This cannot be done, and the printed circuit board cannot be adjusted with the printed circuit board mounted in a predetermined position. Therefore, conventionally, an extension board having a shape similar to that of a printed circuit board and having a connector that can be connected to a connector on the storage case side at one end and a connector that can be connected to a connector on the printed circuit board at the opposite end is provided on the printed circuit board. Instead, the connector of the printed circuit board was inserted into the connector of the extension substrate, and the printed circuit board was positioned outside the storage case to adjust the printed circuit board.

Problems to be Solved by the Invention However, in such a conventional configuration, an extension board is necessary for adjusting the printed circuit board, and the extension board must be prepared at all times, which makes the work troublesome and causes noise due to the extension board. There was a problem such as the possibility of

The present invention has been made in view of the above problems, and an object of the present invention is to provide a printed circuit board housing that can adjust a printed circuit board without using an extension substrate.

Means for Solving the Problems In order to solve the above problems, the present invention provides at least a first connector and a second connector on each printed circuit board housed in a storage case, and the first connector is provided on each printed circuit board. A common circuit connection part, the second connector is a circuit connection part unique to each printed circuit board, while the board housing case has a first connector corresponding to the first connector of each printed circuit board and each printed circuit board. A structure is provided in which a second connector corresponding to the second connector is provided, the second connector is held in a substrate storage case so that the mounting position can be changed, and at least one side surface of the substrate storage case is cut out. It is equipped with.

Operation The present invention can change the mounting position of the storage-case-side second connector corresponding to the second connector that constitutes the connection part of the circuit unique to each printed circuit board by the above-described configuration, so it should be adjusted. Position the second connector on the storage case side corresponding to the printed circuit board at the end of the side of the storage case that is cut out, and set the printed circuit board at that position. Therefore, since the printed circuit board to be adjusted is located on the side surface that is cut out, the printed circuit board can be approached from the outside of the storage case, and the adjustment can be performed while the printed circuit board is inserted into the storage case.

Embodiments Embodiments of the present invention shown in the drawings will be described below. FIG. 1 is a perspective view showing an embodiment of the present invention. In the figure, a printed circuit board housing, generally designated by reference numeral 1, comprises a large number of printed circuit boards 2 and a housing case 3 housing the printed circuit boards 2. Each printed circuit board 2 is provided with a first connector 4 and a second connector 5 on its side edge, the first connector 4 constitutes a circuit connecting part common to each printed circuit board, and the second connector 5 is used for each printed circuit board. It is designed to make the circuit connections unique to the board. On the other hand, the storage case 3 has guides 7 and 8 for guiding the printed circuit boards 2 on the upper and lower inner surfaces thereof, and a mother board 9 is fixed to the inner side surface. A first connector 10 corresponding to the first connector 4 of each printed circuit board 2 is fixed to the motherboard 9. Further, a second connector 11 corresponding to the second connector of each printed circuit board 2 is arranged above it. The second connector 11 is connected to the mother board 9 by a flexible lead wire (not shown),
In addition, it is detachably attached to the side wall of the storage case 3 with screws or the like. Thus, any second connector 11 can be arranged at both ends of the printed circuit board group. In addition, there are large windows 12 on both sides of the storage case 3,
13 is cut out.

Next, a printed circuit board adjusting operation in the printed circuit board housing 1 having the above structure will be described. Print board 2 to be adjusted
A is pulled out, and the second connector 11a on the side of the storage case corresponding to the second connector 5 of the printed board is moved to the outermost position (indicated by reference numeral 11A). If another second connector is already attached at this position, it can be removed and moved to an appropriate position. Next, the pulled-out printed circuit board 2a is set at the position of the second connector 11A. At this time, the first connector on the side of the storage case 3
Since 10 is common to each printed circuit board 2, there is no need to transfer it and the one fixed to the mother board 9 can be used as it is. The printed circuit board 2a thus transferred has one side facing the window 12,
The components on one side of the printed circuit board can be approached from the outside, and the printed circuit board is adjusted in this state. When it is necessary to adjust the opposite surface of the printed circuit board, the second connector on the storage case side is moved to the position indicated by reference numeral 11B, and the printed circuit board is also moved in the same manner, so that the opposite side surface is the window 13 Will be exposed. The printed circuit board may be adjusted in this state. If only one side of the printed circuit board needs to be adjusted, the window on both sides should be
It is not necessary to provide 12, 13 and only one of them is required.

Here, the printed circuit board storage position in the storage case and the first connectors 10 may be the same as the required number of printed circuit boards, but one or two more than that may be provided and the window 12,
It is preferable to always open the position next to 13 for adjustment because the work of replacing the printed circuit board for adjustment becomes easy.

In the above embodiment, the first connector forming the circuit connecting portion common to each printed circuit board and the second connector forming the circuit connecting portion specific to each printed circuit board are provided one by one. The number of connectors is not limited to two, and in that case, multiple connectors on the side of the storage case that correspond to the multiple connectors that make up the circuit board specific to the printed circuit board are all attached to the storage case. The position may be held so that it can be changed.

EFFECTS OF THE INVENTION As will be apparent from the above description, the present invention provides a printed circuit board housing in which a large number of printed circuit boards are housed, in which a housing case-side connector corresponding to a connector that constitutes a unique circuit connecting portion of each printed board is provided. By making it possible to change the mounting position with respect to the storage case and cutting out the side surface of the storage case, it is possible to install the printed circuit board to be adjusted directly next to the cut out side surface, and in this state the printed circuit board can be adjusted, This has the effect of not requiring an extension substrate.
