JP 2000-260507 A

  The invention described in Patent Document 1 is configured such that each circuit board can be conducted by fitting a male connector and a female connector that are soldered and mounted on each circuit board. However, since the connector is mounted on the circuit board by soldering, the assembling work becomes complicated, and the workability of the assembling work of the circuit board is deteriorated.

  Thus, there is a technical problem to be solved in order to simplify the assembling work when connecting the circuit boards and improve workability, and the present invention aims to solve this problem.

  The present invention has been proposed in order to achieve the above object, and is a circuit board connecting device for connecting one circuit board with wiring and the other circuit board with a connector, Provided with recessed portions on both the front and back sides of the connector along the outer peripheral edge, formed so that each circuit board can be fixed to the recessed portion, and provided with a pattern on the edge of the circuit board, When the terminal is attached to the concave portion of the connector and the circuit board is fixed to the concave portion of the connector, the terminal of the connector and the pattern of the circuit board are formed so as to be in pressure contact with each other and fixed to the connector. Provided is a circuit board connecting device configured to allow electrical connection between a circuit board and a circuit board on the back side.

  The circuit board connecting device of the present invention is provided so that concave portions of the same type as the circuit board to which the connector is connected are formed on both the front and back surfaces of the connector, and the circuit board can be fixed to the concave portion. . Further, a pattern is disposed on the outer edge portion of the circuit board so that it can be pressed against a terminal disposed in the recessed portion of the connector.

  Thus, if the circuit boards are respectively fixed to the recessed portions of the connector, the circuit boards on both the front and back sides are conducted through the terminals of the connector. Therefore, the conventional work of soldering the connector to the circuit board and the positioning work for fitting the female connector and the male connector are unnecessary, and the workability of the assembling work to make the circuit board conductive. This has the advantage of reducing labor and contributing to cost reduction.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 is an exploded perspective view of one circuit board 10, the other circuit board 11, and a connector 12. On the one circuit board 10, various electronic components 13, 13,... 10 is wired. Further, as shown in FIGS. 1 to 3, patterns 14, 14... Are arranged on the outer edge portion of the circuit board 10.

  1, 4, and 5, various electronic components 15, 15... Are placed on the other circuit board 11 in the same manner as the circuit board 10, and patterns 16, 16 ... are arranged.

  On the other hand, the connector 12 is formed of a synthetic resin as shown in FIGS. 1, 6, and 7. The recessed portions 17 and 17 are formed in substantially the same shape as the outer peripheral edges of the circuit boards 10 and 11, and the circuit boards 10 and 11 can be fixed to the recessed portions 17 and 17. Is formed. Further, terminals 18, 18,... Are attached to the outer peripheral edge of the connector 12 through the upper and lower recessed portions 17, 17.

  Thus, when one circuit board 10 and the other circuit board 11 are brought into conduction, the circuit boards 10 and 11 are respectively fitted and fixed to the upper and lower recessed portions 17 and 17 of the connector 12. At this time, the patterns 14, 14... Of the circuit board 10 and the patterns 16, 16... Of the circuit board 11 are in pressure contact with the terminals 18, 18. The Therefore, the process of soldering the connector 12 to the circuit board 10 or 11 as in the prior art becomes unnecessary, and further, the positioning work between the circuit board 10 and the circuit board 11 becomes unnecessary, so that the assembling work is simplified. This can reduce labor and contribute to cost reduction.

  8 to 11 show other embodiments, in which covers 21, 21... That can slide the edge of the connector 19 inward and outward are mounted, and the four sides of the recessed portions 20, 20 of the connector 19. Each of the edges is configured so as to be open and coverable. When the circuit boards 10, 11 are fixed, the covers 21, 21,. Thereafter, the circuit boards 10, 11 are fitted into the recessed portions 20, 20 and the covers 21, 21, etc. are slid inward so that the edges of the circuit boards 10, 11 are connected to the connector 19. The circuit boards 10 and 11 are fixed to the connector 19 by being sandwiched between the edge and the inner surfaces of the covers 21, 21.

  At this time, since the patterns 22, 22,..., 23, 23,... Of the circuit boards 10, 11 are in pressure contact with the terminals 24, 24, etc. of the connector 19, the circuit board 10 and the circuit board 11 are electrically connected. Also in this embodiment, since the soldering work and the positioning work between the circuit board 10 and the circuit board 11 are not necessary as described above, the workability can be improved and the labor of the assembling work can be reduced. At the same time, it can contribute to cost reduction.

  It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
