Description

  The present invention relates to a circuit board for an electronic device such as a DVD player.

Inside the casing of the electronic device, circuit boards and mechanical parts necessary for realizing the function of the electronic device are arranged. This is, for example, as seen in Patent Document 1.
JP-A-2005-295146 (page 5-7, FIGS. 1 and 2)

  In recent years, electronic devices are required to be miniaturized, but their functions are so sophisticated that parts are often arranged in a housing at high density. It is a matter of course that the components are arranged so that the components overlap each other when viewed from a certain direction.

  Other members may be processed behind the circuit board, for example, by screwing. There is no problem if the circuit board is assembled by attaching the circuit board after screwing the other member, but there are cases where this is not possible. For example, a circuit board is fixed first, a cable is connected thereto, and then other members are screwed.

  In the case described above, there is no problem as long as the circuit board is notched so as not to obstruct the screwing. However, if the notch is provided, the function as a circuit board, for example, the function as a ground pattern is deteriorated. Therefore, it is desirable to keep the circuit board as complete as possible.

  The present invention has been made in response to the above-described demand, and provides a circuit board for electronic equipment that does not impair the function as a circuit board while enabling processing and operation of members disposed behind. Objective.

And a connecting device that connects the separable area where the separation has been performed and the remaining region of the circuit board to recover the original shape of the circuit board. The connecting tool is made of a soft synthetic resin and has a plate-like main portion. The lower surface is formed with a connecting pin that fits into the through hole formed in the separable region and a connecting pin that fits into the through hole formed in the remaining region, and the separable region is provided with a wiring pattern, The wiring pattern of the separable area and the wiring pattern of the remaining area are characterized in that the electrical connection is maintained by a plurality of jumper lines even after the separable area is separated.

  According to this configuration, by fixing the circuit board and then separating the separable region, it is possible to execute the processing / operation of the member disposed behind the circuit board. Then, after the work is completed, the separable area and the remaining area of the circuit board are connected with a connector to restore the original shape of the circuit board, whereby the circuit board can perform the function originally expected. Since the dimensional error and the position error of the through hole can be absorbed by the elasticity of the connecting tool, the connection between the separable area and the remaining area of the circuit board is easy. In addition, the electrical connection realized by a plurality of jumper lines allows the circuit configuration of the entire circuit board to be kept the same before and after the separation, and there is no need to make an electrical connection again.

  According to a fifth aspect of the present invention, in the electronic device circuit board according to the fourth aspect, the electrical connection is made by a plurality of jumper wires.

  According to this configuration, electrical connection between the wiring pattern in the separable region and the wiring pattern in the remaining region can be easily realized.

  As described above, the circuit board for electronic equipment according to the present invention is provided with a separable area in a part of the circuit board in order to process and operate a member disposed behind, and the separable area is separated to provide a rear member. After the separation / separation of the separable area, the separable area where separation was performed and the remaining area of the circuit board are coupled with a connector to restore the original shape of the circuit board. The circuit board can perform the function originally expected. In addition, the wiring pattern in the separable area and the wiring pattern in the remaining area maintain electrical connection even after separation of the separable area is performed, so that the circuit configuration of the entire circuit board is kept the same before and after the separation. And there is no need to make another electrical connection.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a partial perspective view of the inside of the electronic device housing, FIG. 2 is a partial perspective view of the inside of the electronic device housing showing a state different from FIG. 1, and FIG. 3 is a partial perspective view of the inside of the electronic device housing showing a different state. 4 is a perspective view of a member, and FIG. 5 is a cross-sectional view of a circuit board and a connector.

  FIG. 1 shows the inside of a DVD player casing. The housing itself is not shown. The player mechanism 1, the AV board 10, and the main board 20 are fixed inside the casing. The main board 20 is a circuit board according to the present invention.

  The player mechanism section 1 includes a sheet metal chassis, and a part of the chassis projects sideways as shown in FIG. The tab 2 is provided with a through hole 3 and is screwed to the casing through a screw 4 in the through hole 3.

  The AV board 10 is arranged at the same height as the player mechanism unit 1 and is fixed to the casing with screws (not shown). The AV board 10 is formed with elongated holes 13 and 14 through which flat cables 11 and 12 (only shown by virtual lines) connected to the main board 20 are passed.

  The main board 20 is arranged at a position higher than the player mechanism unit 1 and the AV board 10. A boss 21 is erected on the inner surface of the housing, and one corner of the main board 20 is fixed to the boss 21 with screws 22. The fixed main board 20 comes to a position overlapping (interfering) above the tab 2 of the player mechanism unit 1.

  After the main board 20 is fixed in this way, the flat cables 11 and 12 are connected to the main board 20. This is a procedure for facilitating the connection of the flat cables 11 and 12. Thereafter, the player mechanism unit 1 is set up with screws 4.

  The main substrate 20 has a separable region 20 a that overlaps the tab 2. Between the remaining region 20b and the separable region 20a, a separation groove 20d is formed in addition to a narrow connecting portion 20c at the edge of the substrate. This is a measure for enabling the separable region 20a to be separated with a small force.

  Through holes 23 are formed at both ends of the separable region 20a. A through hole 24 is also formed in the remaining region 20 b at a location adjacent to the through hole 23. The through-holes 23 and 24 are fitted with couplings described later.

  A wiring pattern (not shown) is formed on the surface of the separable region 20a and the surface of the remaining region 20b. The wiring pattern of the separable region 20a and the wiring pattern of the remaining region 20b are electrically connected by a plurality of jumper lines 25, thereby forming one complete wiring pattern.

  At the stage of fixing the player mechanism 1 with the screws 4, the connecting portion 20c is broken as shown in FIG. 2 to separate the separable area 20a. Even after the separation is performed, the electrical connection between the wiring pattern of the separable region 20a and the wiring pattern of the remaining region 20b is maintained by the jumper wire 25.

  The separated separable area 20a is moved to a position where it does not interfere with the screw 4 and a driver (not shown) for turning the screw 4, and the screw 2 is screwed on the tab 2.

  When the screwing of the tab 2 is completed, the separable area 20a is returned to the original position as shown in FIG. 3, and the separable area 20a and the remaining area 20b are connected by the connector 30 to restore the original shape of the main board 20. The electrical connection between the wiring pattern of the separable region 20a and the wiring pattern of the remaining region 20b is maintained by the jumper line 25.

  The connecting tool 30 is made of a soft synthetic resin, and has two connecting pins 30b fitted into the through holes 23 and 24 formed on the lower surface of the main portion 30a having a rectangular plate shape. Since the dimensional error and the position error of the through holes 23 and 24 can be absorbed by the elasticity of the connector 30, it is easy to fit the connecting pin 30b into the through holes 23 and 24. The connecting pin 30b has a mushroom-shaped head and does not easily come off after being fitted into the through holes 23 and 24. Thereby, the connection of the separable region 20a and the remaining region 20b by the connector 30 becomes strong.

  Although the embodiments of the present invention have been described above, various modifications can be made without departing from the spirit of the invention.

  The present invention can be used for circuit boards in general electronic equipment.
