Abstract

(57) [Abstract] [Purpose] When assembling assembled parts that need to contact the protruding parts in the case, the assembled parts interfere with the protruding parts due to tolerances or misalignment during assembly, and the assembly is hindered. Prevent that. [Constitution] In an assembly part module assembled by using a guide pin, the guide pin has a tip part at a position where the interval between the assembly part and the projecting part is wide open, and a root part in contact with each other, The guide pins are arranged so as to be inclined with respect to the base.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an assembly part module assembled by using a guide pin.

[0002]

[Prior Art]

 As shown in FIG. 2, the conventional assembly part module has a guide pin 1 arranged perpendicularly to the upper surface of the base body 5 at a desired position of the base body 5 arranged in the case 8 and the guide described above. The base part 9 of the assembly part having a hole for fitting the pin 1 is fitted, and the assembly part 2 is assembled in a desired position. At this time, the position of the assembled parts on the plane perpendicular to the assembly direction does not change.

[0003]

[Problems to be solved by the device]

 However, in the conventional assembly component module, as shown in FIG. 2, when there is a projecting portion 4 arranged so as to come into contact with or approach the assembly component in the case as shown in FIG. As shown in FIG. 3, there is a possibility that the assembled parts may interfere with the projecting portions, making it difficult to assemble, and there is a problem that the assembly may be hindered particularly in the case of automatic assembly.

Therefore, in order to solve such a conventional problem, an object of the present invention is to provide a space between the assembled component and the projecting portion so as not to interfere with each other when the assembled component is assembled. Then, at the end of the assembling of the assembling parts, it is possible to obtain an assembling parts module in which the assembling parts can come into contact with or come close to each other.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a structure in which guide pins are obliquely arranged in the assembly component module so that the assembly component and the projecting portion have a desired positional relationship. By having a shape with a certain root part and a tip part at a position where the assembly part and the protruding part are filled and separated, at the start of the assembly of the assembly part, the assembly part and the protruding part are separated from each other. There is a sufficient space between them, and at the end of the assembling, the assembling parts and the projecting portions have a desired positional relationship.

[0006]

[Action]

 In the assembled component module configured as described above, at the time of starting the assembly of the assembled component, the guide pin tip for the assembled component allows the assembly component and the projecting portion to be assembled without interference. As the assembling parts are installed, the assembling parts approach the projecting portion by the side surface of the assembling parts guide pin, and at the end of assembling, the assembling parts are guided by the root part of the assembling parts. The part and the protruding portion come into contact with or come close to each other.

【Example】

 An embodiment of this invention will be described below with reference to the drawings. Here, a switch spring for a small electronic device is used as an example of the assembled component. In FIG. 1, a base body 5 mounted on a case 8 having a protruding portion 4 arranged so as to come into contact with the switch spring tip portion 3 is disposed at a desired position with a tilt with respect to the base body 5. A switch spring base 9 having a switch spring hole 10 that fits the guide pin 1 is fitted into the guide pin 1 thus formed, so that the switch spring 2 is assembled at a desired position. The built-in method is a drop-type assembly method that is often used in automatic assembly.

In FIG. 4, the side surface of the guide pin 1 moves toward the guide pin root portion 7 as the switch spring 2 is assembled from above. In FIG. 5, the switch spring 2 is separated from the projecting portion 4 by the guide pin tip portion 6 when the switch spring 2 is started to be assembled, and by the guide pin root portion 7 when the assembly is completed. The tip portion 3 of the switch spring contacts the protruding portion 4.

In FIG. 6, when the incorporation of the switch spring 2 according to the present invention is viewed from above, the switch spring 2 moves in parallel and approaches the projecting portion 4. In FIG. 7, by rotating the direction of the guide pin 1 on the side farther from the switch spring tip 3 by 180 °, the switch spring base 9 rotates during assembly, and the switch spring tip 3 is rotated. In, a larger position change can be given.

FIG. 8 shows another embodiment of the guide pin. In this embodiment, only the side surface of the protruding portion 4 side is inclined with respect to the base body 5.

[0011]

[Effect of the device]

 As described above, according to the present invention, in the assembled component module, the guide pin is disposed obliquely with respect to the base body so that the protruding portion and the assembled component are in contact with each other at the end of the assembly of the assembled component. Further, at the start of the assembling, there is an effect that a sufficient space is provided between the protruding portion and the assembling component, and it is possible to prevent the assembling from interfering with the assembling.
