Description

[Detailed Description of the Invention] [Technical Field] This invention relates to an electronic board block that houses a board for mounting electronic components such as a printed circuit board.

[Background technology]

Conventional electronic board blocks incorporating boards for mounting electronic components, which are applied to the display section and operation section of a control panel, are as shown in FIGS. 3 to 5.
That is, in FIG. 3, the lower box 30 supports the lower substrate 31 and the upper substrate 32 on the support protrusions 33, and the lower box 30
The connector (male) 36 of the boards 31 and 32 and the connector (female) 38 of the belt-shaped control line 37 are connected through a connector insertion window 35 formed in the side plate 34 of the board.

However, this electronic board block
When the connector (female) 38 is not connected or during the process until the connection is completed, foreign objects can easily enter the lower box 30 through the connector insertion window 35, and the direction in which the connector is inserted and the direction in which the control line 37 extends from the lower box 30 are Since they are the same, there is a drawback that the connector (female) 38 tends to come off when the control line 37 is pulled.

On the other hand, in the electronic board blocks shown in FIGS. 4 and 5, a connector (male) 40 is provided through the side plate 39 of the case 38, and the connector (male) 40 and the board 41 are connected with a crossover wire 42. It is something. 43 is a connector (female), and 44 is its control line.

However, in this electronic board block, since the direction in which the connector (female) 43 is inserted and the direction in which the control wire 44 is pulled out is the same, the connector (female) 43 is easily pulled out by pulling the control wire 44 as described above, and the crossover wire 42 Since this is necessary, work efficiency is poor, and furthermore, when a connector is not required depending on the type of internal unit, there is a disadvantage that foreign matter may enter unless the connector mounting hole 40a of the connector (male) 40 is closed.

[Purpose of invention]

The purpose of this invention is to provide an electronic board block that prevents foreign matter from entering and also prevents connectors from coming off.

[Structure of the idea]

This device consists of a lower box and an upper lid that closes the opening of the lower box, and the lower box has a partition plate that divides the interior into two parts including the opening, and the partition plate is connected to the lower box from the opening side. The box has a vertical slit extending toward the bottom side of the box, and a locking groove facing the vertical slit is formed in a side plate opposite to the partition plate of at least one section divided by the partition plate, and further A case in which an opening window is formed on one side plate of a section partitioned by the partition plate, and a vertical slit having a length approximately the same as the inner width dimension in the thickness direction of the partition plate of this case. a board into which an intermediate part is inserted, one end part of which is locked in the groove and prevented from being removed by the upper cover; and a connector which is erected parallel to the partition plate at a part of the board having the opening window. It is equipped with the following.

According to the configuration of this invention, the board is inserted into the vertical slit of the middle partition plate and the locking groove of the bottom box through the opening of the lower box, and the board is fixed by closing the opening with the top cover, so the board is attached to the case. A device that is fixed to the board and allows the terminals of the board to protrude into the recess (for example,
27649), the board can be easily fixed to the case. In addition, since the connector is installed upright in the part facing the opening window of the board separated by a partition plate, the direction in which the control line is pulled out from the case and the direction in which the connector is inserted are at right angles, making it difficult to remove the connector. Also, compared to a connector in which the connector protrudes from the case (for example, Utility Model Application No. 57-154187), the connector is less likely to be damaged during assembly. Furthermore, even if foreign matter enters through the opening window, it is blocked by the partition plate, thereby preventing it from entering the other section of the lower box.

An embodiment of this invention is shown in FIGS. 1 and 2. That is, in this electronic board block, a case 1 consists of a lower box 2 and an upper lid 3, and the lower box 2 is provided with a vertical partition plate 4 close to one side plate, and the interior is divided into two horizontally (2a, 2b). )do. A vertical slit 5 is formed in this middle partition plate 4, and a groove 9 with a rib 8 is formed in the side plates 6, 7 of the separated lower box 2, and the side plate 6 of the section 2b partitioned by the middle partition plate 4 and this An opening window 11 is cut out and extends across the side plate 10 adjacent to the side plate 10 . The substrate 12 is a flat plate having a width equal to the inner height of the lower box 2 and a length equal to the width of the lower box 2, and is passed through the vertical slit 5 and supported by the groove 9 at both ends. And the upper opening 1 of the lower box 2
When the top cover 3 is placed on the top cover 3, the board 12 is completely fixed without coming off. Note that the grooves 9 of the side plates 6 and 7 may be formed only on either one. The open window 11 side of the substrate 12 partitioned by the partition plate 4 is the exposed portion 1.
2a, and a connector (male) 14 is erected on this exposed portion 12a. In this case, connector 14
The charging portion 15 is provided on the partition plate 4 side with respect to the housing 16.

With this configuration, foreign matter does not enter the interior of the case 1 partitioned by the partition plate 4, and failures due to foreign matter can be prevented. Also, a part of the board 12 is exposed from the partition plate 4 of the case 1,
Since the connector 14 is installed upright on the exposed part 12a, the insertion direction of the connector (female) 17 is parallel to the surface of the partition plate 4, as shown in FIG.
Connector (female) 17 even if the control line 18 is drawn because it is perpendicular to the direction in which it extends to case 1 of 8.
is difficult to remove. Also, the pins (live parts) 15 of the connector 14 are connected to the partition plate 4 and the connector housing 16.
Because it is protected by being sandwiched between the two, it can be expected that accidents such as external ground faults will be significantly reduced. Furthermore, since the connectors 14 and 17 are housed inside the case 1 with respect to their outer dimensions, accidents in which external forces are applied to the connectors 14 and 17 and cause damage to the connectors 14 and 17 are greatly reduced.

Furthermore, as shown in Fig. 2, multiple cases 1, 1'
... are installed side by side on panel A of the control panel, and when interconnecting wiring 19, in the conventional example (third
4), the cases 1 and 1' are lined up in the width direction of the control lines 37 and 44, so it is necessary to twist the control lines 37 and 44 to connect them, but in the embodiment, the lines 19 are Because they are lined up, there is no need to twist the crossover wiring 19.

[Effect of idea]

According to this invention, the board is inserted into the vertical slit of the partition plate and the locking groove of the lower box through the opening of the lower box,
In order to fix the board by blocking the opening with the top cover, the board is fixed to the case and the terminals of the board protrude into the recess (for example, Utility Model Publication No. 59-27649).
The board can be easily fixed to the case compared to the previous version. In addition, since the connector is installed upright in the part facing the opening window of the board separated by a partition plate, the direction in which the control line is pulled out from the case and the direction in which the connector is inserted are at right angles, making it difficult to remove the connector. Also, compared to a connector in which the connector protrudes from the case (for example, Utility Model Application No. 57-154187), the connector is less likely to be damaged during assembly. Furthermore, even if foreign matter enters through the opening window, it is blocked by the partition plate, so there is an effect that it is possible to prevent foreign matter from entering the other section of the lower box.
