However, the guide rail 23 with the above configuration,
Since the claw members 24a, 24a are attached to the printed circuit board mounting portion of the housing by utilizing their elasticity, the guide rail 23 is inclined with respect to the wall surface of the printed circuit board mounting portion of the housing 21, as shown in FIG. There was a fear that the printed circuit board would be mounted diagonally.
Furthermore, in order to attach the guide rail 23 to the printed circuit board mounting portion inside the housing, it is necessary to simultaneously insert the engaging portions 24 near both ends of the guide rail 23 into the holes provided in the printed circuit board mounting portion within the housing. Therefore, when assembling an electronic device in which a large number of guide rails 23 are attached, the task of attaching the guide rails 23 is also time consuming and difficult.

In order to solve the above problems, the present invention is a rod-shaped body with a rectangular cross section that is attached to a flat printed circuit board mounting part inside the housing and has a thin groove formed in the center of the top surface into which the end of the printed circuit board fits. In a guide rail for mounting a printed circuit board, one end of the guide rail is extended to have a stepped engagement surface with the top surface of the guide rail, and the distance from the bottom surface of the guide rail is approximately equal to the thickness of the flat printed circuit board mounting portion. In addition to forming a rigid support part, an engaging part consisting of two claw members is formed at the bottom near the other end, and the flat printed circuit board mounting part has a support part insertion hole into which the support part of the guide rail is inserted. Provide an engaging part insertion hole into which the engaging part is inserted, rotate the guide rail into the supporting part insertion hole, insert the supporting part of the guide rail into the engaging part insertion hole, and then guide the guide rail using the supporting part as a fulcrum. The engaging part of the rail is inserted, and the flat printed circuit board mounting part is held between the bottom surface of the guide rail, the supporting part, and the shoulder part of the claw member.

With the above configuration, the guide rail is fixed by sandwiching the printed circuit board attachment part in the housing between the guide rail bottom surface, the upper surface of the support member, and the shoulder of the claw member, but the support part is fixed at one end of the guide rail. The guide rail is rigid because it is formed by stretching it, and the guide rail is fixed by firmly clamping the printed circuit board mounting part in the housing between the engagement surface of this rigid support part and the bottom surface of the guide rail. The rails are firmly fixed to the housing, eliminating problems such as diagonal mounting of printed circuit boards.
Also, when attaching the guide rail to the housing, as described later, after inserting the guide rail support part into the hole provided in the printed circuit board mounting part inside the housing,
The guide rail can be attached to the housing by simply inserting the claw member of the engaging portion into the hole provided in the printed circuit board attaching portion.

The guide rail 13 is made of a resin material, and a narrow groove 13b into which the end of the printed circuit board fits is formed in the center of the upper surface 13a in the length direction, and one end extends to form the upper surface 13a of the guide rail 13. A rigid support portion 15 is formed which has a stepped engagement surface 15a and is rigid. As will be described later, the distance t 1 between the engagement surface 15a of the support portion 15 and the bottom surface 13c of the guide rail 13 is approximately the same as the thickness of the printed circuit board mounting portion in the housing in which the printed circuit board is mounted. The width dimension of the support part 15 is the same as the width dimension of the guide rail 13, and the thickness dimension t2 of the support part 15 is formed smaller than the thickness dimension t3 of the guide rail 13. The connecting portion 15c that connects the two is thick on the guide rail 13 side and gradually becomes thinner toward the support portion 15, and has a so-called trapezoidal shape, so that it has a strong structure. Further, the support part 15 is divided into two parts by a cutout part 15b in the central part. The bottom surface 13c of the guide rail 13 and the engagement surface 15a of the support portion 15 are formed in equilibrium.

る電子機器の組立て作業が極めて容易になる。 Figure 5 a, b, and c show guide rail 1 of the above structure.
FIG. 3 is a diagram for explaining the order in which the PCB 3 is attached to the printed circuit board attaching portion in the housing. As shown in FIG.
a and 11b are provided, and as shown in FIG.
Then, as shown by arrow B, the guide rail 13 is pushed down so that the two claw members 14a of the engaging part 14 are inserted into the holes 11b, respectively. As a result, the shoulder portion 14 of the claw member 14a of the engaging portion 14
When b reaches the bottom surface 13c of the guide rail 13, the claw member 14a spreads outward and the shoulder portion 14b engages with the bottom surface 13c of the guide rail 13, thereby fixing the guide rail 13 to the printed circuit board mounting portion 1 in the housing.
Fixed to 1. At this time, as mentioned above, the bottom surface 13c of the guide rail 13 and the engagement surface 15a of the support part 15
and the distance t 1 between the claw member 14a and the shoulder 14b and the thickness t 4 of the printed circuit board attachment part 11 inside the housing.
Since the dimensions are approximately the same as that of
c, the shoulder portion 14b, and the top surface 15a, and the bottom surface 13c of the guide rail 13 is in close contact with the surface of the printed circuit board mounting portion 11 inside the housing. Moreover, since the support part 15 has strong rigidity, the guide rail 1
3 is not easily inclined with respect to the printed circuit board mounting portion 11 in the housing, so there is no problem of mounting the printed circuit board diagonally.Also, when installing the guide rail 13, first place the support portion 15 on the printed circuit board mounting portion. The guide rail 13 can be attached to the printed circuit board attachment part 11 inside the housing by simply inserting the guide rail 13 into the hole 11a of the engagement part 11 and inserting the claw member 14a of the engaging part 14 into the hole 11b. Assembling work of electronic equipment that requires the rail 13 becomes extremely easy.
