Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, reference numeral 1 denotes a substrate holder, and in the present embodiment, the substrate holder 1 is made of a synthetic resin and is formed in a substantially quadrangular prism shape. The substrate holder 1 is formed by projecting a pair of elastic hooks 2 and 4 from the lower side thereof.

Each of the pair of hooks 2 and 4 is formed such that the tips are bent inward in a "L" shape. As shown in FIG. 2, the mounting plate 6 has a pair of mounting holes 8, 1 in advance.
0 is formed at an interval corresponding to the interval between the pair of hooks 2 and 4. The mounting plate 6 is a chassis or a main board of an electric device.

When the hooks 2 and 4 are inserted into the mounting holes 8 and 10 while being bent against their elasticity, the hooks 2 and 4 return to their original shape by elasticity, and the hooks 2 and 4 The mounting plate 6 is sandwiched between the pair of mounting holes 8 and 10 so as not to be easily pulled out as it is.

A groove 12 is formed in the substrate holder 1 along the standing direction, and the groove 12 of the substrate holder 1 is formed so as to open on the upper surface 1a and the side surface 1b. Groove 1
The width of 2 is formed so that a board 14 such as a printed board to be held can be inserted. In addition, the substrate holder 1 includes:
A rectangular hole 16 is formed, and the rectangular hole 16 is formed so as to penetrate perpendicularly to the standing direction. By forming the rectangular hole 16, the release operation portion 18 is formed in a plate shape having elasticity. One hook 2 is arranged on the extension of the plate-shaped release operation portion 18. As shown in FIG. 3, when the release operation unit 18 is pushed into the rectangular hole 16, the release operation unit 18 bends in an arc shape, and one hook 2 escapes outward.

On the other hand, an elastic piece 24 is formed by cutting out the bottom of the groove 12 so as to communicate with the rectangular hole 16 in a U-shape, and an elastic piece 24 is formed. ing. When the substrate 14 is inserted into the groove 12, the elastic piece 24 is elastically deformed by the substrate 14, the elastic piece 24 enters the rectangular hole 16, and the elastic piece 24 contacts the back side of the release operation unit 18. It is configured as follows.

Further, a groove 1 is provided on the upper surface 1a of the substrate holder 1.
An elastic engagement piece 26 is provided along the extension direction of the second engagement piece 2. The engagement piece 26 includes an engagement portion 26a protruding toward the substrate 14 and a lever portion 26b formed at the distal end side. By pressing the lever portion 26b, the engagement piece 26 is curved, and the engagement portion 26a is formed so as to be able to retreat from above the extension of the groove 12. On the other hand, the substrate 14
A notch 14a into which the engaging portion 26a enters when the substrate 14 is inserted into the groove 12 is formed.

Next, the substrate holder 1 of the above-described embodiment is described.
The operation of will be described. First, as shown in FIG. 2, hooks 2 and 4 are inserted into the mounting holes 8 and 10 of the mounting plate 6, respectively. At that time, the hooks 2 and 4 are elastically deformed and bent, and are inserted with an interval therebetween. After the insertion is completed, the hooks 2 and 4 return to the original state, and the hooks 2 and 4 are erected so as to embrace the mounting plate 6.

As shown in FIG. 5, the two substrate holders 1 are erected on the mounting plate 6 with their grooves 12 facing each other. Then, the board 14 is inserted along the two grooves 12, but when the corner of the board 14 hits the engaging portion 26a,
The engaging piece 26 is bent, and the engaging portion 26a escapes outward (see FIG. 3A).

Accordingly, the substrate 14 can be inserted into the groove 12. When the substrate 14 inserted into the groove 12 hits the elastic piece 24, the elastic piece 24 is elastically deformed toward the rectangular hole 16.
Then, the elastic piece 24 comes into contact with the back side of the release operation unit 18, and the release operation unit 18 cannot be operated even if the release operation unit 18 is bent with the tip of a finger or the like.
Therefore, in a use state where the substrate 14 is inserted into the groove 12,
The hooks 2 and 4 do not escape from the mounting holes 8 and 10 so that they can be pulled out.

When the board 14 reaches the lower end of the groove 12 and the insertion is completed, the elasticity of the engaging piece 26 causes the engaging portion 26a to enter the notch 14a. Thereby, the groove 12 of the substrate 14 is
(See FIG. 3B). At this time, when the connectors 30 and 32 are provided,
They are also connected.

On the other hand, when removing the substrate holder 1 from the mounting plate 6, first, the lever portion 26b of the engagement piece 26 is pushed outward. As a result, the engaging piece 26 is curved, and the engaging portion 26
a retracts from the notch 14a. In this state, the substrate 14 is pulled out along the groove 12. As a result, the elastic piece 24 returns to the original state protruding from the rectangular hole 16 into the groove 12.

Then, as shown in FIG.
8 is pushed into the rectangular hole 16 with the tip of a finger or the like to bend in an arc shape. Due to the elastic deformation of the release operation portion 18, one of the hooks 2 escapes outward, and the interval between the pair of hooks 2, 4 is widened. When the substrate holder 1 is pulled up in this state, the hooks 2 and 4 are pulled out from the mounting holes 8 and 10, and the substrate holder 1 can be removed.

Next, a substrate holder according to a second embodiment different from the above-described embodiment will be described with reference to FIG.
Note that the same members as those of the substrate holder 1 of the above-described embodiment are denoted by the same reference numerals, and detailed description is omitted. The substrate holder 50 is formed by the groove 12 of the substrate holder 1 described above.
Is formed on the side surface 50c different from the 90-degree direction so that the penetration direction of the rectangular hole 16 and the depth direction are the same direction. The engaging piece 54 also differs from the above-described engaging piece 26 in the 90-degree direction, and the engaging portion 54a and the lever portion 54b are formed similarly.

With such a shape, when the substrate holder 50 is formed of a synthetic resin, the configuration of a mold (not shown) is simplified, and the substrate holder 50 is divided into upper and lower parts without using a slide mold. Resin molding using a metal mold. As described above, the present invention is not limited to such embodiments at all, and can be implemented in various modes without departing from the gist of the present invention.
