Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a component mounting device for attaching a component such as a printed circuit board of an electronic device to a base so as to be rotatably openable and closable.

BACKGROUND ART Conventionally, as a method for attaching two parts so that they can be rotated to open and close, a special part such as a latch or a hinge has been used.

Hereinafter, with reference to FIG. 3, an example of a component mounting device using the above-mentioned conventional nylon latch will be explained. In FIG. 3, reference numeral 1 denotes a base, and support plates 2a and 2b are provided on a part of the base so as to face each other at a predetermined interval. 3 is the support plate 2
A support shaft is provided on the inner wall of a so as to protrude toward the other support plate 2b, and 4 is a hole bored in the other support plate 2b. Further, 5 is a movable member to which, for example, a printed circuit board or the like is mounted, and tongue portions 6a and 6b are opposed to each other at a distance slightly smaller than the distance between the support plates 2a and 2b. and holes 7a and 7b are provided in them.
is drilled.

To assemble the conventional component mounting device configured as described above, first, insert the support shaft 3 into the hole 7a.
With the holes 2b and 7b overlapped, a nylon latch 8 made of synthetic resin or the like may be inserted into the holes.

Problems to be Solved by the Invention However, the above structure has the problem that it requires many man-hours and becomes complicated to assemble because it is composed of three or more parts. Furthermore, when hinges are used, the number of parts increases, leading to an increase in manufacturing costs.

In view of the above-mentioned problems, the present invention provides a parts mounting device that can reduce the number of man-hours and improve workability by reducing the number of parts.

Means for Solving the Problems In order to solve the above problems, the component mounting device of the present invention is a device for rotatably and removably mounting a component to be mounted on a base material. One of the pair of support parts formed on both sides is provided with a first support shaft that has a retaining member at its tip, and the other support part is provided with one of the second support shaft and a hole. and a slit through which the retaining prevention member can be inserted and a hole through which the first support shaft can be inserted are communicated with one of the pair of tongue members formed on both sides of the attached component. The other tongue member is provided with one of the hole and the spindle that are related to either the second spindle and the hole.

Effects The present invention has the above-described configuration, which reduces the number of parts, improves workability, and lowers manufacturing costs.

Embodiments Hereinafter, the present invention will be explained based on illustrated embodiments.

In FIG. 1, reference numeral 11 denotes a base material such as a frame, and a part of the base material is provided with first and second support parts 12a and 12b facing each other at a predetermined interval. Note that the distance between these opposing inner walls is _L1 . 13a is the first support part 1
It is a first support shaft provided on the inner wall of 2a so as to protrude in the direction of the other second support part 12b,
Let its diameter be D ₁ . 13b is a retaining member integrally formed at the tip of the first support shaft 13a, and its thickness is t. Note that the first
The supporting shaft 13a and the retaining member 13b may be formed integrally with the base material 11 using synthetic resin or the like. 1
Reference numeral 4 denotes a second support shaft having a diameter of D ₂ and projecting from the outer wall of the second support portion 12b.

Reference numeral 15 denotes a movable member which is a mounted part on which a printed circuit board or the like is mounted, and a part of the movable member has first and _second tongue pieces at a distance _L2 which is slightly smaller than the above-mentioned L1. 16a and 16b are provided to face each other, and the first
Holes 17 and 18 having inner diameters slightly larger than the diameters D ₁ and D ₂ of the second support shafts 13a and 14 are bored, respectively. Note that the first tongue portion 1
6a, a slit 19 having a gap s slightly larger than the thickness t of the retaining member 13b is provided in the hole 1.
It is provided so as to communicate with 7.

To assemble the component mounting device of this embodiment configured as described above, first insert the second support shaft 1 into the hole 18.
4 through the slit 19 and the hole 1.
What is necessary is to insert the retaining member 13b into the hole 7 and then insert the first support shaft 13a into the hole 17.

In this way, the diameter of the first support shaft 13a
D ₁ and the gap s of the slit 19 have a relationship of D ₁ > s, and in the range of rotation of the movable member 15 that does not completely match the retaining member 13b of the slit 19, the first tongue piece When the inner wall of the portion 16a comes into contact with the retaining member 13b, the movable member 1
5 is rotatably supported on the base member 11 in a completely prevented manner.

In the embodiment shown in FIG. 1, the second support shaft 14 is provided on the second support portion 12b, and the hole 18 is provided on the second tongue portion 16b. may be the opposite. The example in that case is shown in the second example.
As shown in the figure. That is, the hole 2 is formed in the second support portion 12b.
0, and the second tongue portion 16b is provided with a support shaft 21 that protrudes from the inner wall thereof toward the hole 17. It goes without saying that similar actions and effects can be obtained.

Effects of the invention As described above, according to the invention, the parts to be mounted can be freely rotated and detached with one touch, without using special mounting parts such as conventional nail latches or hinges. As a result, excellent effects such as a reduction in the number of parts and manufacturing costs can be obtained.
