Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a storage and fixing device for protecting electronic components such as printed circuit boards that are attached to a housing that houses instruments.

[Conventional technology]

Connecting terminals that electrically connect electrical components housed in instrument housings, etc. with external power sources, lamp loads, etc., or printed circuit boards with circuit elements for driving them, are generally used to protect electrical components from external flying objects, and to protect them from external flying objects. In order to prevent poor electrical continuity, the cable is disposed inside the housing and is configured to lead out a connection cord to an external power source or electrical load through an insertion hole formed at an appropriate location.

For example, as disclosed in Japanese Utility Model Application Publication No. 52-106170, a structure is adopted in which a printed circuit board with circuit components arranged inside the housing is housed, and a connection cord with the outside is led out through a grommet installed in the insertion hole of the housing. be done.

[The problem that the idea attempts to solve]

However, such a structure not only requires extremely difficult work to lead out the connection cord to the outside after the printed circuit board etc. is housed and fixed in the housing, but also requires an extremely difficult work when an electrical connector is connected to the cord terminal. When the connector is installed in the housing, a fairly large insertion hole must be formed in the housing to lead out the connector, which has the disadvantage that the assembly work is troublesome and the protection function from foreign objects cannot be satisfied.

[Means to solve the problem]

The present invention aims to solve the above-mentioned drawbacks and provide a storage and fixing device that has a structure that is easy to assemble and ensures protection from foreign objects. A storage section is formed, and after storing printed circuit boards with electrical components arranged in this storage section, the storage section is covered with a cover member that can be attached to the housing, and furthermore, the direction in which the connection cord with the outside is led is restricted. a cylindrical support part for forming a guide groove on the side periphery of the housing part, and forming a tongue piece for regulating the direction in which the electrical cord is led out at a corresponding position on the cover member, and pressing and fixing the printed circuit board from the lower surface of the cover member; The device is characterized in that it is formed hanging down and fixed by screwing through the screw insertion hole.

〔Example〕

Embodiments of the present invention will be described below based on the accompanying drawings.

Figures 1 and 2 illustrate the storage structure of a device in which a color display section is provided in a part of the housing that houses the instruments, and a small lamp that illuminates and displays the display section is connected to a printed circuit board. A color display section 3 (for example, a gear position display on a two-wheeled vehicle) is attached to a part of the housing 2 that houses the instrument body 1, and the display is displayed by lighting a lamp 4 arranged behind the color display section 3. , the lamp 4 is connected to a terminal provided upright on the electrical path of the printed circuit board 5. On the outer peripheral surface of the housing 2, behind the color display section 3, there is a
A storage recess 7 is formed surrounded by an inner wall continuous with the back wall 6, and an insertion hole 8 is formed at the bottom of the storage recess 7 through which the lamp 4 projects toward the color display section 3 side. Further, screw holes 9 are formed on both sides of the bottom of the storage recess 7, and when the printed circuit board 5 is disposed in the storage recess 7, insertion holes 10 formed on both sides of the printed circuit board 5 are formed.
Their positional relationship is set so that they overlap. Furthermore, a part of the side circumference of the storage recess 7 is provided with a printed circuit board 5.
A guide groove 12 is formed to regulate the direction in which the electric cord 11 connected to the electric cord 11 is led out. Reference numeral 13 denotes a cover member that covers the opening of the storage recess 7;
A tongue piece 14 for regulating the direction in which the electric cord 11 is led out is formed protrudingly at a position corresponding to the housing recess 7 on the lower surface of both sides of the cover member 13.
A cylindrical support portion 16 is suspended from a position corresponding to the screw hole 9, which presses the printed circuit board 5 during fixation and allows the screw 15 to be tightened at the same time.

Therefore, after the printed circuit board 5 is stored in the storage recess 7 surrounded by the inner wall continuous with the outer peripheral surface of the housing 2, the cover member 13 is attached so as to cover the storage recess 7, and the support part 16 is inserted. The printed circuit board 5 can be firmly fixed by simply tightening and fixing the screws 15 through the holes, and the printed circuit board 5 can be securely protected from foreign objects in the same way as if the printed circuit board 5 were housed in the housing 2. be able to.

That is, according to the above structure, the printed circuit board 5 can be stored and fixed from the outside of the housing 2, so that the troublesome work of leading out the electrical cord 11 after storing and securing the printed circuit board 5 in the housing as in the conventional case is not required. After the instrument body 1 is assembled as an instrument device housed in the housing 2, it can be freely attached as an external component.
It has an excellent effect in that it can be removed and replaced extremely easily even in the event of component failure without disassembling the instrument device itself.

In addition, the guiding groove 12 extending from the storage recess 7 and the tongue piece 14 protruding from the cover member 13 can regulate the direction in which the electrical cord 11 is led out and can be easily routed, making it easy to connect to an external power source or lamp load. This also makes it easier to store the printed circuit board 5 and greatly improves work efficiency.

Furthermore, the printed circuit board 5 is fixed using a cover member 13.
Since this structure can be performed at the same time as the fixing work to the housing 2, the structure can be simplified without the need for special mounting members. Since the storage recess 7 formed protruding from the housing 2 is covered with the cover member 13, the overall design of the instrument device can be balanced, and the shape is almost the same as when it is stored in the housing 2 without creating unnecessary protrusions. It is something that can be secured.

FIG. 3 shows another example of the shape of the storage part formed on the outer circumferential surface of the housing 2, and particularly illustrates a structure having a connector part that electrically connects with the internal electrical components of the housing 2. be.

That is, the storage part formed on the outer circumferential surface of the housing 2 has a cylindrical part 1 that can communicate with the inside of the housing 2.
7 has a shape that hangs inward, a printed circuit board 18 is placed on the periphery of the lower end, and a flange 19 with a screw hole is formed. In this case, the printed circuit board 18 has connection terminals 21 erected thereon for connecting to the connector 20 that connects to the electrical components inside the housing 2, and the electrical cord 22 that connects the printed circuit board 18 to an external power source, etc. is shown in FIG. And it is led out through the guide groove 23 similarly to the embodiment explained in FIG. The cover member 24 that covers the cylindrical portion 17 serving as a storage portion also forms a support portion 25 as in the above embodiment, and simultaneous fixing by screwing can be achieved in the same manner, so the details will be omitted.

[Effect of idea]

As described in detail above, the present invention forms a storage section on the outer circumferential surface of a housing that stores instruments, etc., in which a printed circuit board with electrical components is arranged, and
By providing a cover member that covers this storage portion and fixing it to the housing, and forming a cylindrical support portion that presses and fixes the printed circuit board on the lower surface of this cover member, after storing the printed circuit board in the storage portion, the cover member is fixed to the housing. It can be fixed together with other parts at the same time.
Furthermore, the cord guide groove and tongue piece allow the cord to be pulled out easily by regulating the direction in which it is pulled out, which not only simplifies assembly work but also allows electrical components such as printed circuit boards to be treated as external components. There is no need to disassemble the housing itself when replacing parts, and it is possible to provide a storage device with extremely high practical value that does not create unnecessary external protrusions while ensuring protection from foreign objects. It is something.
