Description

  The present invention relates to a printed wiring board, and more particularly to a mounting position of a connector having a lock function.

  Conventionally, in a printed wiring board on which many connectors for connecting loads and other printed wiring boards are mounted, the size of the printed wiring board can be reduced by adjoining the connectors in two rows and minimizing the space between the connectors. I try to figure it out. Further, for example, the size of the printed wiring board is reduced by using the size of the connector as one side of the printed wiring board (see Patent Document 1).

  FIG. 4A is a perspective view of a printed wiring board 301 in which a large number of connectors 302 are adjacent to each other in two rows so that the size can be reduced. In this printed wiring board 301, the connectors 302 are partially disposed adjacent to each other in two rows, the space between the connectors is reduced, and the large electronic component 303 and the small chip component 304 are disposed in the remaining space. The wiring board 301 is downsized.

  FIG. 4B is a perspective view of the printed wiring board 301 in which one side is adjusted to the size of the large connector 305 so that the size can be reduced. is there. In this printed wiring board 301, one side is set to a necessary minimum size that allows the large connector 305 to be mounted, and the large electronic component 303, the small chip component 304, and the small connector 302 are arranged in the remaining space. .

  By the way, in the conventional printed wiring board, as a connector mounted on the printed wiring board, for example, there is a connector serving as an interface for supplying power from a power supply board to a circuit formed on the printed wiring board.

  And, as such a connector, when inserting the connector on the power supply board side, the connector on the power supply board side can be securely fitted, and the connector having a locking function that is less likely to cause problems such as half-insertion. used. Recently, a connector having a lock function is also used as a connector as an interface of a signal line.

  Here, when using a connector having such a locking function, it is assumed that the connector having the locking function is provided around the lock portion so that the unlocking operation can be performed on the assumption that the mating connector is pulled out. Space is needed to allow human fingers to enter.

  However, for example, when a connector having a lock function is mounted adjacent to each other as shown in FIG. 4A, if a space for unlocking operation is secured, the printed wiring board becomes large. In addition, even when a large connector 305 is disposed at the end of the printed wiring board 301 as shown in FIG. 4B, if a large component or the like is disposed around the lock portion of the connector 305, the unlocking operation is performed. Space cannot be secured.

  Accordingly, the present invention has been made in view of such a current situation, and provides a printed wiring board that can secure a space for unlocking a connector having a locking function and can be miniaturized. It is intended to do.

The present invention relates to a printed wiring board on which electronic components are mounted, and includes a board body and a plurality of connectors having a lock function including a lock portion that locks another connector that is mounted on and connected to the board body. The plurality of connectors with a lock function are mounted so that the lock portions face each other, and the facing lock portions share an operation space necessary for unlocking operation, and the lock is placed in the shared operation space. The electronic component having a height such that the part can be released is mounted .

  As in the present invention, by mounting so that the lock portions face each other and between the lock portions so as to form a common operation space necessary for the lock release operation, the connector for unlocking the connector with the lock function can be used. Space can be secured and downsizing can be achieved.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view of a printed wiring board according to an embodiment of the present invention. In FIG. 1, 10 is a printed wiring board, and 4 is a printed wiring board body (hereinafter referred to as a board body). Reference numerals 1, 1A, and 1B denote a plurality of connectors with a lock function (hereinafter referred to as connectors with locks), which are examples of electronic components mounted on the board body 4, and the connectors with locks 1, 1A, and 1B each include a lock portion. 2 has. For example, the lock portion 2 is adapted to be fitted to a lock portion 7a of a female connector 7 with a lock shown in FIG.

  The substrate body 4 is mounted, for example, in an electronic device housing, and has a mold or an insertion hole (not shown) formed by drilling. 1A and 1B are inserted. A large electronic component 5 and a small chip component 6 are mounted on the substrate body 4, and the large electronic component 5 and the small chip component 6 are connected in a pattern (not shown) printed on the substrate main body 4.

  Here, in the board body 4 of the present embodiment, when the two connectors with locks 1A and 1B among the connectors with locks 1 and 1A and 1B to be inserted (mounted) are inserted into the board body 4, the locking portion 2 are arranged to face each other.

  FIG. 2A is a perspective view showing a state immediately before the female connector 7 with lock provided with the lock portion 7a is fitted to the connector 1B with lock, and the female connector 7 with lock to be fitted is a substrate. It is inserted vertically into the lock connector 1B mounted on the main body 4. FIG. 2B is a perspective view showing a state where the lock portion 7a of the female connector 7 with lock is inserted into the connector 1B with lock.

  Here, as described above, when the female connector 7 with lock inserted into the connector 1B with lock is pulled out, in order to release the lock by the lock portion 2, as described above, a human finger is placed around the lock portion. A space (space) is needed to enter.

  Therefore, in the present embodiment, the lock release operation space 3 which is an operation space necessary for the lock release operation by the lock portion 2 is replaced with two lock connectors 1A shown in FIG. , 1B. In the present embodiment, the mounting interval L between the two connectors with locks 1A and 1B is set to 15 mm to 40 mm.

  Thus, when the lock part 2 is released by mounting the two lock connectors 1A and 1B so that the lock part 2 faces to share the unlocking space 3, the lock connector 1A is released. , 1B can be unlocked without interfering with each other. Further, the size of the substrate body 4 is not unnecessarily increased, and the substrate body 4 can be downsized.

  As described above, in the present embodiment, the connectors with locks 1A and 1B are made to share the operation space necessary for the unlocking operation between the lock portions 2 so that the lock portions 2 face each other. Is implemented. As a result, a space for unlocking the connectors with locks 1A and 1B can be secured, and the printed wiring board 10 can be downsized.

  In this unlocking space 3, electronic parts such as chip parts can be arranged as long as the lock part 2 can be unlocked. FIG. 3 shows a state in which the connectors 1A and 1B with locks are arranged on the board body 4 so that the lock portions 2 face each other, and the small chip component 6 is arranged in the space 3 for unlocking operation.

  Here, the small chip component 6 arranged in the space 3 for unlocking operation has a height H1 that does not exceed the height H2 of the lock portion 2. Then, by disposing the small chip component 6 having the height H1 not exceeding the height H2 of the lock portion 2 in the space 3 for unlocking operation in this way, the unlocking operation of the lock portion 2 of the connector 1 with lock can be performed. It becomes possible.

  Thus, by disposing the electronic components such as the small chip component 6 having a height of H2 or less in the space 3 for unlocking operation, the unlocking operation of the lock portion 2 of the connector 1 with lock can be performed, and the printed wiring The substrate 10 can be downsized.
