Description

  The present invention relates to an on-vehicle electric device group. More specifically, the present invention relates to an in-vehicle electric device group that can easily and reliably identify the type of electric board from the outside of the housing.

  Generally, many grades are set for a vehicle. Vehicle equipment is determined according to the grade. In addition to this, a large number of optional devices are lined up, and the equipment of the vehicle can be freely selected according to the intention of the user. In particular, in a vehicle-mounted control device, the types of electric boards accommodated in the control device are diversified along with the diversification of such vehicle equipment.

  On the other hand, the shape of the control device is usually the same regardless of the equipment of the vehicle due to restrictions on vehicle mounting, and even if the type of electric board is different, it is accommodated in one type of housing. It is configured as follows.

  However, the housing generally does not have a structure for confirming the inside thereof, and once the control device is assembled, the type of the electric board accommodated in the housing is confirmed later. It is difficult. For example, the type of the electric board is specified after connecting the control device to the controlled part and confirming the operation. This is a very time-consuming work, and equipment for checking the operation is also required. In addition, depending on the type of the electric board accommodated in the housing of the control device, a different seal is attached, or an identification mark is written or stamped to identify the type of the electric board. Things are also done. However, the method of sticking the identification sticker on the surface of the housing or writing the identification mark on the surface of the housing not only increases the work cost for pasting or writing, but also causes human error (pasting error or forgetting). Can not be completely prevented. Further, the marking of the identification mark has a problem that the number of parts increases and the number of molds increases.

  Patent Document 1 discloses a medical electrical device in which a small window for confirming the inside of a housing is formed in the housing in order to specify the types of a plurality of electric boards accommodated in the housing. It is disclosed.

JP 2002-78667 A

  However, in the technique of Patent Document 1, foreign matter (water, dust, etc.) enters the inside of the casing from a small window for confirming the inside of the casing, and there is a risk that a functional defect occurs. If, for example, a transparent panel is attached to the confirmation window in order to cope with this problem, the cost of parts will increase due to an increase in the number of parts, and the cost will increase due to an increase in attachment work. Furthermore, even if the inside of the housing can be looked into from the small window, the inside of the housing is dark, so that it is not easy to confirm from the outside. If a light source is added for the confirmation, the number of parts is further increased and the cost is increased due to an increase in mounting work.

  The present invention has been made in view of the above-described conventional problems. The type of the electric board accommodated in the housing can be easily and surely secured while preventing foreign matter from entering the housing. It aims at providing the vehicle-mounted electrical equipment group which can be identified from the exterior of a body.

According to the vehicle-mounted electrical equipment group of the present invention, the electrical board on which the electronic component is mounted and the housing that houses the electrical board are provided, and the housing sandwiches the electrical board in the thickness direction. The first member and the second member are housed in a plurality of ways, and each of the first member and the second member sandwiches the electric substrate while being in close contact with the periphery of the electric substrate. has a part, to the each clamping portion of the first member, respectively, the peripheral edge of the circuit board through holes and the clamping portion is adjacent to the through hole for exposing the specific portion of the circuit board to the outside A screw into which a screw for fastening the first member and the second member is inserted while being in close contact with each other, and the screw is inserted into each holding portion of the second member while being screwed. holes are formed, the periphery of the circuit board , A vehicle-mounted electrical device group consisting of vehicle-mounted electrical devices provided with a mark for determining the type of the electrical board exposed from a specific through-hole among the through-holes, The type of the electric board accommodated in the electric device is the color of the electric board exposed from each through hole formed in each clamping portion of the first member of each on- vehicle electric device or the electric board The above object can be achieved by being able to be identified by information combining the mark displayed on the surface and the position of the through hole.

  According to the in-vehicle electric device group according to claim 1 of the present invention, the type of the electric board accommodated in each in-vehicle electric device is formed in the clamping portion of the first member of each in-vehicle electric device. A plurality of types of electric boards can be identified by the combination of the color of the electric board exposed from each of the through-holes or the mark displayed on the surface of the electric board and the position of the hole. Can be determined.

In addition, a screw 4 (described later) is screwed into the first placement portion 22a, the second placement portion 22b, the third placement portion 22c, the fourth placement portion 22d, and the fifth placement portion 22e. Screw holes 22a2, 22b1, 22c2, 22d1 and 22e1 for insertion are formed. The positions of the screw holes 22a2, 22b1, 22c2, and 22d1 differ depending on the specifications of the electric board 3. When the electrical board 3 having the specification shown in FIG. 2A is accommodated in the housing 2, the receiving board 22 shown in FIG. 1 is used and the electrical board 3 having the specification shown in FIG. 1 is housed in the housing 2, the receiving tool 22 is used in which the position of the screw hole is different from the position shown in FIG. 1.

  The sandwiching portion of the housing 2 includes a first placement portion 22a and a first pressing portion 21a, a second placement portion 22b and a second pressing portion 21b, a third placement portion 22c, a third pressing portion 21c, and a fourth placement. It is comprised from the mounting part 22d and the 4th press part 21d. Specifically, in a state where the electric board 3 is accommodated in the housing 2, the first pressing portion 21 a of the lid 21 and the first mounting portion 22 a face each other to sandwich the electric board 3, and the lid 21 The second pressing portion 21b and the second mounting portion 22b face each other to sandwich the electric substrate 3, and the third pressing portion 21c of the lid 21 and the third mounting portion 22c face each other to sandwich the electric substrate 3, and the lid The 21st 4th press part 21d and the 4th mounting part 22d face each other, and the electric board | substrate 3 is clamped. When the electric board 3 is sandwiched, of the two holes formed in the pressing portions 21a to 21d, the one of the notches 3a to 3d formed in the electric board 3 is below one of the holes. Any one of them is located, and any one of the regions A1 to A4 where the identification mark of the electric board 3 is displayed is located under the other hole.

  As shown in FIGS. 1 and 15, the connector 5 is for electrically connecting the electric board 3 to an external device. One end of the connector 5 is in contact with the electric board 3, and the other end protrudes outside the housing 2 through a connector insertion hole 21 e formed in the housing 2.

  The screw 4 is for fastening the lid 21 and the receiver 22. As shown in FIG. 1, holes 21e1 formed in the fifth pressing portion 21e at the four corners of the housing 2, the first pressing portion 21a, the second pressing portion 21b, the third pressing portion 21c, and the fourth pressing portion 21d. Are inserted into either one of the two holes formed in accordance with the specification of the control device 100 (automatic specification or manual specification). In this embodiment, as shown in FIG. 1, since the electric substrate 3 of FIG. 2A is used, the screw 4 is inserted into the hole 21a2, the hole 21b1, the hole 21c2, and the hole 21d2. When the electric board 3 of FIG. 2B is used, the screw 4 is inserted into the hole 21a1, the hole 21b2, the hole 21c1, and the hole 21d1. Therefore, in this embodiment, the type of the electric board 3 accommodated in the housing 2 can be identified, and whether the control device 100 is the automatic specification or the manual specification is also confirmed by the insertion position of the screw 4. It is possible only by doing.

  FIG. 16 is a cross-sectional view taken along the line XX of FIG. 17 and shows a state where the electric board 3 is sandwiched between the receiving member 22 and the lid 21 of the housing 2.

Therefore, foreign matter can be effectively prevented from entering the inside of the housing 2 through the hole for exposing the identification mark. Moreover, since the clamping part of the housing | casing 2 and the electric substrate 3 are closely_contact | adhered, it is easy to visually recognize the identification mark provided on the electric substrate 3 without providing a light source or the like.

  A method for identifying the type of the electric board 3 in the in-vehicle electric device of the present invention with the above configuration will be described below.

  FIG. 17 is a plan view for explaining a method for determining the type of the electric board 3 accommodated in the in-vehicle electric device 100 according to the first embodiment. FIG. When the board is accommodated inside the casing, (b) is when the electrical board of FIG. 7 is accommodated inside the casing, and (c) is when the electrical board of FIG. 9 is accommodated inside the casing. Is shown.

  In the control device 100 shown in FIGS. 17A to 17C, when specifying the type of the electric board 3 accommodated in the housing 2, first, it is formed on the lid 21 of the housing 2. Of the holes 21a1, 21a2, 21b1, 21b2, 21c1, 21c2, 21d1, and 21d2, the holes to which the screws 4 are not inserted, here, the holes 21a1, 21b2, 21c1, and 21d2 are exposed. The color of the surface of the electric substrate 3 is confirmed. For example, in the control device 100 shown in FIG. 17A, the surface of the printed wiring board 32, that is, a green color, is exposed from the hole 21a1 formed in the first pressing portion 21a. In addition, a white identification mark m2 printed on the printed wiring board 32 is exposed from the hole 21b2 formed in the second pressing portion 21b. In addition, a white identification mark m3 printed on the printed wiring board 32 is exposed from the hole 21c1 formed in the third pressing portion 21c. Further, the surface of the printed wiring board 32, that is, a green color is exposed from the hole 21d2 formed in the fourth pressing portion 21d. Table 1 summarizes the colors of the portions exposed from the holes 21a1, 21b2, 21c1, and 21d2 formed in the housing 2 of FIGS. 17 (a) to 17 (c).

  In other words, in the present embodiment, the type of the electric board 3 accommodated in the housing 2 is displayed in the green color of the printed wiring board 32 exposed from each hole or on the surface of the printed wiring board 32. The identification mark is easily and reliably specified by information combining the white color of the identification mark and the position of the hole.

  According to the on-vehicle electric device 100 of the first embodiment described above, the lid 21 of the housing 2 has a plurality of holes 21a1, 21b2, 21c1, and 21d2 sandwiching the periphery of the electric board 3, Depending on the type of the electric substrate 3, the electric substrate 3 or an identification mark displayed on the surface of the electric substrate 3 is exposed from each hole formed in the portion facing the electric substrate 3. doing. Thereby, in order to position and fix the electric substrate 3 in the housing 2, the portions provided in close contact with the electric substrate 3 (that is, the first pressing portion 21a, the second pressing portion 21b, the third pressing portion 21c). The type of the electric board 3 accommodated in the housing 2 can be identified by utilizing the fourth pressing portion 21d). Therefore, it is possible to easily and reliably identify the type of the electric board 3 accommodated in the housing 2 from the outside of the housing 2 while preventing foreign matter from entering the housing 2.

  In the first embodiment, the description has been given of the form using the screw hole as the hole for displaying the identification mark printed on the surface of the electric substrate 3, but the present invention is not limited to this. As long as the hole is formed in the portion of the housing 2 that sandwiches the periphery of the electric substrate 3 and faces the electric substrate 3, the screw hole may not be used. For example, a dedicated hole for displaying an identification mark on the lid 21 may be newly formed.

  In the first embodiment, the positions of the notches 3a, 3b, 3c, and 3d formed at the four positions of the electric substrate 3 are two types as shown in FIGS. 2 (a) and (b). However, the present invention is not limited to this, and by changing the positions of the cutouts 3a, 3b, 3c, and 3d at each of the above locations, it is possible to change the position of the cutouts to the maximum. 24 = 16 distinctions can be made. It goes without saying that if the number of cutouts further increases, the number that can be discriminated further increases.

  In the first embodiment, the description has been given of the form in which the space for passing the screw 4 formed on the electric substrate 3 is the notches 3a, 3b, 3c, and 3d. However, the present invention is not limited to this. Instead, a configuration in which through holes are formed in the electric substrate 3 may be used as a space for passing the screw 4 formed in the electric substrate 3.

  In the first embodiment, the description has been given of the mode in which four holes for displaying the identification mark are provided in the lid 21. However, the present invention is not limited to this, and for displaying the identification mark. The number of holes does not matter. In the case where four or more holes for displaying the identification mark are provided, more electric boards can be identified than in the case of the first embodiment.

  In the first embodiment, the case where the identification marks m1 to m4 are only white is described. However, the present invention is not limited to this, and the color of the identification mark is not limited. By setting several types of identification mark colors, it is possible to identify more electric boards than in the first embodiment. In particular, when several types of identification mark colors are set, various electric boards can be identified even if the number of holes for displaying the identification mark is small.
