Description

Technical Field

[0001] The present invention relates to a frame into which a module storage unit is inserted, namely a module storage frame, which houses a circuit board for mounting modules. Background Technology

[0002] For example, a circuit board for mounting communication modules such as memory cards or SD cards is housed in a module housing unit. The module housing unit is inserted into the frame and secured. Typically, the module housing unit's latching mechanism, i.e., its locking claws, engages with slots located in the frame to secure it.

[0003] For example, conventionally, the locking claws provided in the battery holder, which is equivalent to a module storage unit, engage with the slots in the frame to secure the battery holder. Moreover, when the module storage unit is disassembled, the locking is released by inserting a rod-shaped member through a disassembly hole provided on the side of the frame (for example, see Patent Document 1).

[0004] Patent Document 1: Japanese Utility Model Application Publication No. 5-31106

[0005] However, in the existing snap-fit ​​structure of the modular storage unit as described above, an additional rod-shaped component is required when disassembling the modular storage unit from the frame, thus increasing the number of new components. Summary of the Invention

[0006] The present invention was proposed to solve the above-mentioned problems, and its purpose is to obtain a modular storage frame with a reduced number of components.

[0007] The modular storage frame of the present invention comprises: a modular storage unit, which is configured to store a module between a cover having a flexible engaging claw and a housing having an engaging hole for engaging with the engaging claw; and a frame comprising a cover and a base covered by the cover, wherein the base has an opening for inserting the modular storage unit, and the engaging claw for engaging with the engaging hole protrudes from the engaging hole toward the base, and the protruding engaging claw engages with an engaging groove provided on the base.

[0008] The effects of the invention

[0009] The modular storage frame involved in this invention has a locking claw that engages with a locking hole, which protrudes from the locking hole toward the base. The protruding locking claw engages with a locking groove provided on the base, thereby allowing the modular storage unit to be inserted and removed from the frame without the need for new parts, thus reducing the number of parts.

[0026] Implementation method 1.

[0027] Figure 1 This is an example of a perspective view of the module storage frame 4 according to this embodiment. The structure of the module storage frame 4 will be described in turn.

[0028] Figure 2 This is a perspective view of the frame 9 and the module storage unit 8 after the module storage unit 8 has been pulled out from the module storage frame 4. That is, the module storage frame 4 is in the state where the module storage unit 8 is inserted into and housed in the frame 9. Figure 2 Arrow M indicates the orientation in which the module storage unit 8 is inserted into the frame 9. The module storage unit 8 is... Figure 2 The arrow M shown is inserted into frame 9, becoming... Figure 1 The state shown.

[0029] Figure 3 This is an exploded perspective view of module storage box 4. For example... Figure 3 As shown, the module housing frame 4 is configured to sandwich a printed wiring board 2 between a cover 1 and a base 3. The cover 1 and the base 3 are formed, for example, of a glass fiber reinforced engineering plastic. The cover 1 covers the base 3. Furthermore, the cover 1 has an opening 1a for inserting a module housing unit 8. Similarly, the base 3 also has an opening 3a for inserting a module housing unit 8. The openings 1a and 3a overlap each other when the cover 1 covers the base 3.

[0030] Figure 4 From the Z direction Figure 3 The diagram shows an oblique view of the base 3. (See figure.) Figure 4 As shown, a locking groove 31 is provided on the base 3. The details of how the locking groove 31 is set will be described later.

[0031] Figure 5 This is an example of a perspective view of module storage unit 8. The construction of module storage unit 8 will be explained in sequence.

[0032] Figure 6 yes Figure 5 The exploded perspective view of module storage unit 8 shown. (See attached image.) Figure 6As shown, the module storage unit 8 is constructed by storing the circuit board 6 on which the module 61 is mounted between the cover 5 and the housing 7. The cover 5 and the housing 7 are formed of a material with a low modulus of elasticity, such as PBT (Polybutylene terephthalate) or nylon, which does not contain glass fibers. Furthermore, with the circuit board 6 stored in the housing 7 and cover 5, the housing 7 has a plug-in portion 72 on the side opposite to the cover 5. The plug-in portion 72 in the housing 7 is provided with a disassembly groove 73. Details regarding the arrangement of the disassembly groove 73 will be described later.

[0033] Figure 7 This is a perspective view of the cover 5 that constitutes the modular storage unit 8. The cover 5 is provided with engaging claws 51. Additionally, feet 52 are provided extending from each engaging claw 51. Furthermore, the engaging claws 51 are flexible due to their snap-fit ​​construction, and their front ends are rounded (R-shaped).

[0034] Figure 8 From Figure 1 The diagram shows a cross-sectional view of the module storage frame 4 viewed along the Z-direction from an oblique perspective. The module storage unit 8, housed within the base 3, is secured by the engagement of the locking claw 51 of the cover 5 with the locking groove 31. Details regarding the engagement will be described later.

[0035] Figure 9 The illustration shows the situation when the module storage unit 8 is being inserted or removed from the module storage frame 4. Figure 1 The oblique view shown is a cross-sectional view of the module storage frame 4 viewed in the Z direction. The module storage unit 8 is inserted and removed with the cover 5 and the base 3 having a close-fitting groove 31.

[0036] Figure 10 This is a side view of module storage unit 8. Figure 11 The modular storage unit 8 is in the state of having the housing 7 and the cover 5 installed. Figure 10 Arrow B-B section view. Figure 12 This indicates the state in which the cover 5 is being installed on the housing 7. Figure 10 Arrow B-B sectional view.

[0037] like Figures 10-12 As shown, the locking claw 51 of the cover 5 is in a state of elastic deformation due to being pressed into the inner side of the module 61 by the side wall of the housing 7.

[0038] The circuit board 6 is housed in the module storage unit 8 by engaging the locking claws 51 of the cover 5 with the locking holes 71 of the housing 7. The locking claws 51 of the cover 5 and the housing 7 are in a state where they protrude from the side wall of the housing 7 through the locking holes 71.

[0039] Next, the engagement of the locking claws 51 and locking holes 71 of the cover 5 with the locking grooves 31 of the frame 9 will be explained.

[0040] Figure 13 yes Figure 8 An enlarged view of part A shown. (Using...) Figure 13 The following describes the various parts of the engaging claw 51 in the state of engaging with the engaging hole 71.

[0041] like Figure 13 As shown, if the module storage unit 8 is stored in the frame 9, the engaging claw 51 engages with the engaging hole 71 of the housing 7. Furthermore, the engaging claw 51, which engages with the engaging hole 71, protrudes through the engaging hole 71 toward the base 3 and engages with the engaging groove 31 of the base 3.

[0042] like Figure 13 As shown, the engaging claw 51 consists of a fixed surface 51a and an inclined surface 51b. The fixed surface 51a is provided continuing from the foot 52. The fixed surface 51a faces the side of the engaging hole 71. The angle between the fixed surface 51a and the direction in which the module storage unit 8 is inserted into the frame 9 is less than or equal to 90 degrees. The inclined surface 51b is provided continuing from the fixed surface 51a and facing the opening. The angle between the inclined surface 51b and the direction in which the module storage unit 8 is inserted into the frame 9 is less than 90 degrees.

[0043] With the engaging claw 51 engaged with the engaging hole 71 and engaging groove 31, the module storage unit 8 does not detach from the frame 9. For example... Figure 9 As shown, when the operator pulls the module storage unit 8 out of the frame 9 with a certain load, the locking claw 51 elastically deforms and disengages from the locking groove 31, so that the module storage unit 8 can be taken out from the frame 9.

[0044] Figure 14 This is a perspective view of the housing 7. The plug-in / plug-out part 72 is positioned on the housing 7, aligned with the opening 3a of the base 3 and the opening 1a of the cover 1, with the module storage unit 8 housed within the frame 9. Furthermore, a disassembly groove 73 is provided around the entire circumference of the plug-in / plug-out part 72, along the openings 3a and 1a. The operator grasps the disassembly groove 73 to remove the module storage unit 8 from the frame 9.

[0045] When components of equipment such as circuit breakers with modular storage frames 4 are arranged adjacent to the modular storage frame 4, if the disassembly slot 73 is only provided in a portion of the frame, it becomes difficult for the operator to grasp the disassembly slot 73, making it potentially difficult to disassemble the modular storage unit 8 from the frame 9. Therefore, when the modular storage frame 4 is shared, the insertion and removal direction of the modular storage unit 8 is restricted, potentially reducing the design freedom of the equipment.

[0046] However, since the disassembly slot 73 is located around the entire circumference of the insertion and removal part 72, the storage direction of the module storage unit 8 is not limited when the module storage frame 4 is shared, thus increasing the design freedom of the device.

[0047] According to this embodiment, the module storage unit 8 can be disassembled from the frame 9 without adding any components, thus reducing the number of components. Furthermore, the reduction in the number of components helps to control costs. Additionally, since no new components are needed when disassembling the module storage unit 8, the space required for storing the components used during disassembly within the frame 9 can be reduced.

[0048] In addition, the locking claws 51 of the cover 5 are elastic, so the operator gets a clicking sensation when installing the module storage unit 8 into the frame 9. Based on the clicking sensation, the operator can easily determine that the installation is complete.

[0049] In addition, by providing a disassembly groove 73 around the entire circumference of the plug-in portion 72 of the housing 7, the installation direction of the module storage unit 8 is not limited, the sharing of the module storage frame 4 becomes easier, and the design freedom of the device can be improved.
