Description

  The present invention relates to a holder for a plate-shaped electronic component and a storage case for transporting or storing the plate-shaped electronic component. More specifically, the present invention relates to a plate-like electronic component holder and storage case that holds and transports the plate-like electronic component from static electricity.

JP2001-2179A

  Conventionally, plate-like electronic components such as an electronic board (circuit board) and a liquid crystal panel are stored in a storage box opened upward. Such a storage box is partitioned by a plurality of partition plates at predetermined intervals. The electronic boards and the like are individually stored between the partition plates. Then, when the substrates collide with each other and do not damage each other, the substrates can be easily taken out one by one. Further, in order to prevent damage to the electronic substrate or the like due to static electricity, and to provide cushioning properties, the electronic substrate or the like is individually wrapped and stored in an antistatic sheet or bag.

  Patent Document 1 discloses an article storage box shown in FIG. The article storage box 100 includes a rectangular parallelepiped plastic or cardboard box 101 having an upper opening. A pair of locking rails 102 is provided on the upper part of the opposing inner wall 101 a of the box body 101. Between the pair of locking rails 102, both end portions are supported, and a plurality of support rods 103 provided so as to be movable in the longitudinal direction along the locking rails 102 are disposed. A flexible sheet-like member 104 is hung between adjacent ones of the support rods 103 so as to hang down.

  The sheet-like member 104 is a material having conductivity or non-charging properties. The sheet-like member 104 is sequentially hung on the adjacent support rod 103. The portion of the sheet-like member 104 that is bent in a U shape is a storage portion 105 for storing the electronic substrate.

  In general, a storage tool that stores electronic components has a problem of countermeasures against static electricity of the electronic components that are contents and individual storage methods for preventing damage. As described in the prior art, corrugated cardboard and plastic are usually used for the storage device because of its ease of processing, low cost, and light weight. However, since such a thing has almost no conductivity, it is easily charged with static electricity. Therefore, a separate measure for protecting electronic components from static electricity is required. As a countermeasure against static electricity, in the prior art, an electronic component is covered or packed in advance using an antistatic sheet or a bag. However, it is cumbersome to individually package electronic components with an antistatic sheet. Moreover, in the structure which partitions off with a conductive sheet like the technique of patent document 1, the structure is complicated and the number of parts increases.

  On the other hand, the partition plate for individual storage is intended to prevent the plate-like electronic components from colliding with each other and damaging each other. However, the partition plate is often fixed to a predetermined width, and depending on the electronic components to be stored, the partition plate may move between the partition plates and be damaged. On the other hand, in Patent Document 1, by making the partition plate a conductive flexible sheet, the size of the storage box can be reduced by the thickness of the partition plate, and the width of the partition can be increased by the size of the plate-like electronic component. It can be changed depending on the size. However, the strength for preventing damage between adjacent parts or the elasticity for absorbing the impact is not sufficient.

  Accordingly, the present invention has a technical problem to provide a plate-shaped electronic component holder and a storage case with a simple structure capable of integrally performing countermeasures against static electricity and surely holding the plate-shaped electronic component. .

  The plate-like electronic component holder according to the present invention (Claim 1) is formed of conductive corrugated cardboard, and is arranged on a plurality of plate members arranged in parallel in the vertical direction and on the upper and lower ends of the plate members.

The elastic member includes a fixing member that fixes the plate member so as to elastically sandwich the plate member from above and below.

  In such a plate-shaped electronic component holder, it is preferable that the plate material is disposed such that the direction in which the core of the plastic cardboard extends is lateral (Claim 2).

  A storage case for a plate-like electronic component according to the present invention (Claim 3) includes a box-shaped case main body having an upper opening, a lid that closes the opening of the case main body, and an upper part disposed inside the lid. The elastic member, the lower elastic member disposed on the bottom surface of the case main body, and the conductive member disposed in parallel in the vertical direction so as to be elastically sandwiched between the upper and lower elastic members in the case main body. A plurality of plate members, a pressing member that holds the plate members arranged in parallel so as to overlap each other, and a connector that fixes a lid to the case body are provided.

  Such a plate-like electronic component storage case is preferably such that the case body, the lid, and the partition plate are formed of a material having substantially the same surface specific resistance value (Claim 4).

  In addition, it is preferable that the case main body and the lid are formed of a conductive synthetic resin foam (Claim 5).

  The electronic component holder of the present invention (Claim 1) uses conductive plastic corrugated cardboard (pradan) plate material, and sandwiches the plate-like electronic component with the plate material. Can be prevented. Further, as a plate material, a plate-shaped electronic component can be sandwiched between flexible platen plate materials, and the plate materials can be pressed and held by a pressing member. For this reason, the plate material can prevent vibration during movement or conveyance of the plate-like electronic component. Furthermore, plate-like electronic components having different sizes can be held at a time.

  In such a plate-shaped electronic component holder, when the plate material is arranged so that the direction in which the core of the plastic cardboard extends is lateral (Claim 2), the shape of the electronic component is adjusted. The Pradan can be curved. Therefore, the electronic component is surely held.

  The storage case of the present invention includes a box-shaped case main body with an open top and a lid that closes the opening of the case, and the plate-like electronic component can be protected by the case main body and the lid, Easy to store. Moreover, the upper and lower ends of the partition plate can be elastically fixed by the elastic member only by covering. In addition, it can also be used as a passing box at the time of conveyance.

  Further, when the case main body, the lid body and the partition plate are formed of materials having substantially the same surface specific resistance value (Claim 4), from the partition plate to the case main body and the lid body, that is, from the inside to the outside of the case. It is easy to spread static electricity through the air as it is. For this reason, static electricity is difficult to accumulate.

  Further, when the case main body and the lid are made of conductive synthetic resin foam (Claim 5), since all members exhibit conductivity, charging of electronic parts such as static electricity It is possible to reliably prevent failures due to. In addition, each member can exhibit the property corresponding to a use by making foaming ratio and shaping | molding different according to the use used.

The elastic member 4 below is cut at two places from the front side plate 22 to the rear side plate 23 and is divided into three in the left and right longitudinal directions. Therefore, even if a large force is applied, it can bend toward the cut portion. Further, the lower pressing member 6 a (see FIG. 6) is locked to the bottom plate 21 and extends upward along the front side plate 22 through the cut portion. On the other hand, in the vicinity of the upper end of the rear side plate 23, an upper presser member 6b that can be connected to the lower presser member 6a is locked. The plate member 5 can be stacked and pressed from both sides by the pressing members 6a and 6b. Further, near the upper end of the front side plate 22, surface fasteners 6c, 6c for temporary fixing are provided. The temporary fastening fasteners 6c and 6c can be stopped so that the lower pressing members 6a and 6a do not fall down.

  The lid 3 extends vertically from the upper surface 3a that closes the opening of the case main body 2 and the outer edge of the upper surface 3a so that when the case main body 2 is covered, it almost contacts the outer periphery of the case main body 2. It consists of the hook-shaped part 3b arrange | positioned. The upper elastic member 4 is attached to the inside of the upper surface 3a of the lid 3.

As the material of the case main body 2 and the lid body 3, it is preferable to use plate-like members having a surface resistivity of about 5 × 10 ^{3 to} 6 × 10 ⁶ . For example, in order to impart conductivity, a material containing carbon is preferable, and it is preferably formed of a plate-like member obtained by foaming polypropylene.
