Description

  The present invention relates to a mounting board in which an electrical component is mounted on a printed board.

  2. Description of the Related Art Conventionally, a mounting board in which electrical components such as a relay and a connector are mounted on a printed board is known, and is widely used as an internal circuit of an electric junction box for automobiles.

  By the way, in such a mounting board, the configuration of the printed circuit board itself may be different due to differences in the vehicle type, grade, etc., and even if the configuration of the printed circuit board is the same, the specifications of the components to be mounted may be different. Due to the different types and the different types of electrical components, many types of mounting boards are manufactured as products.

  Therefore, the product can be managed by making it possible to identify the mounting boards with different specifications from each other by marking each product number (part number) etc. on various types of mounting boards with different specifications. To be done. For example, in Japanese Patent Laid-Open No. 2000-40860 (Patent Document 1) and Japanese Patent Laid-Open No. 2001-223457 (Patent Document 2), a label indicating a product number, a barcode seal, or the like is attached to a printed circuit board. A conventional structure for identifying a type of mounting board is described. In addition, instead of such a label or bar code seal, a grid-like display area is formed on a printed circuit board by land or silk printing, and an adhesive is applied to a specific grid of the display area. A structure for displaying the difference is proposed.

  However, the structure in which a label or bar code seal indicating the product number or the like is attached to the final product is not preferable because the number of work steps increases and the use of the label or bar code increases the cost. Even in the method of applying an adhesive to a grid-like display area provided on a printed circuit board, a separate process of applying an adhesive is required and the work is complicated. In addition, the amount of information that can be displayed is limited only by the grid-like display, and it is necessary to separately create a part number correspondence table as shown in Table 1 of Patent Document 2 and specify the part number while checking the correspondence table. There is a problem that the work of specifying the product number becomes complicated.

Therefore, at the time of confirming the product numbers of the mounting boards 10 and 12, it can be simultaneously confirmed whether or not the fuse module 18 and the printed boards 14 and 16 are mounted in an incorrect combination.

  As mentioned above, although several embodiment of this invention was explained in full detail, this invention is not limited by the specific description. For example, the optical reading code constituting the component type identification display is not limited to a general one-dimensional bar code. For example, a matrix-type two code formed by combining small squares such as a QR code (registered trademark), for example. Various known optical reading codes such as a two-dimensional bar code and a stack type two-dimensional bar code in which a plurality of one-dimensional bar codes are stacked can be arbitrarily employed. The optical reading code may be a letter, a number, a symbol, or the like as long as it can be read using a known optical reading device.

  Further, in the above-described embodiment, an example in which two types of mounting boards are identified using one type of fuse module and two types of printed boards as electrical components provided with a component type identification display is shown. According to the present invention, it is possible to identify and manage more types of mounting boards by combining a plurality of types of electrical components and a printed board.

In other words, the electrical parts provided with the part type identification display are relays, connectors, fuses, etc., as long as there are multiple types of differences in specifications such as required current values depending on the vehicle type and grade. Various known electrical components that can be mounted on a mounting board, such as a module, can be arbitrarily employed. If there is a difference in type among a plurality of electrical components mounted on a printed circuit board, it is also possible to provide a component type identification display for each electrical component to identify more types of mounting boards. .

  In the above-described embodiment, the component type identification display is provided on the side surface side of the fuse module, but the specific position or the like for providing the component type identification display is not particularly limited. For example, a component type identification display may be provided on the upper surface of an electrical component such as a fuse module so that the component type identification display and the substrate type identification display provided on the upper surface of the printed board can be viewed from the same direction. By adopting such an aspect, it is possible to simultaneously read the component type identification display and the board type identification display from the upper surface side of the mounting substrate using a single optical reader.
