[Problems to be solved by the invention]
The conventional mounting structure of electronic equipment by screw fixing has a drawback that it takes a lot of time for assembly work and lowers production efficiency. In particular, when the option is supported, the front case attached to the rear case must be removed because it is necessary to attach an OP board to the front case. Therefore, there is a drawback that the production efficiency is further reduced.
[0004]
In addition, although the mounting structure of the electronic device described as the conventional example is a screw-less structure, when the option is supported, it is the same as the mounting structure of the conventional electronic device with a general screw fixing. There is a drawback that it takes much time than the assembly work and further reduces the production efficiency. Furthermore, since a tool is required to remove the front case attached to the rear case (because it is removed from the front case by, for example, applying a flathead screwdriver to the nail of the rear case) There is a disadvantage that it is easy to stick. Also, when there are too many claws when replacing the substrate, there is a disadvantage that maintenance is significantly reduced because it is difficult to remove. In addition, since the fitting claw is bent and locked, a large fitting length cannot be secured, and as a result, an excessive impact (for example, a drop impact) is applied. There is a disadvantage that sometimes comes off.
[0005]
Therefore, in the present invention, by removing these drawbacks, the assembly property is improved (so that it can be easily assembled) even when the option is supported, and the mounting structure of the electronic device having a high drop impact property is provided. With the goal.
[0006]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention comprises a housing of an electronic device with three cases of a front case, a rear case, and a bottom case, and a fitting nail for the case (front case, rear case, bottom case). The electronic device is assembled by sliding the case without bending the fitting claw so that the fitting length can be secured sufficiently. In other words, the front case can be moved vertically by setting the fitting length of the claws provided on the back surface of the rear case and the fitting length of the claws provided on the inner surface of the front case to be equal to or greater than the required values. By sliding in the direction, the front unit claw can be fitted into the rear unit claw. In addition to providing a claw on the inner surface of the rear case and providing a hole in the front case for retaining the claw provided on the inner surface of the rear case, the front case can be attached to the rear case. Is.
[0007]
In addition, a protrusion is provided on the lower surface of the rear case, a U-shaped claw is provided on the upper surface of the front case, an L-shaped hole corresponding to the protrusion of the rear case is provided on the lower surface of the bottom case, and a U-shape of the front case is provided on the inner surface of the bottom case. By providing an L-shaped nail corresponding to the nail of the rear case, the bottom case is slid in the horizontal direction so that the protrusion of the rear case is fitted into the L-shaped hole of the bottom case and the L-shaped nail of the bottom case is It is designed to fit into a U-shaped nail. The bottom case can be attached to the rear case and the front case by providing elastic claws on the lower surface of the rear case and providing holes on the lower surface of the bottom frame for insertion of the elastic claws provided on the lower surface of the rear case. It is what I did. Similarly, when disassembling the electronic device, the case (front case, rear case, bottom case) can be slid. As a result, the impact resistance is increased by increasing the fitting length.
[0008]
When the option is supported, a space for attaching the OP substrate (second substrate) is provided in the bottom case, and guide ribs for attaching the OP substrate (second substrate) are provided on the inner surface. As a result, the main unit can be made optional without disassembling the front unit and rear unit (the OP board can be easily attached if necessary), so that assembly and option compatibility are improved. It is a thing. Further, a claw for attaching the substrate (first substrate) to the rear case is provided on the inner surface, and the height direction of the claw and the guide rib is made the same, whereby the substrate (first substrate) and By making the mounting position in the height direction of the OP substrate (second substrate) the same, it is made difficult to receive interference of electromagnetic wave noise.

The receiving apparatus of this embodiment includes a rear unit A, a front unit B, and a bottom unit D as shown in FIGS. Hereinafter, the configuration of each unit will be described.
[0011]
First, the configuration of the rear unit A will be described with reference to FIGS. The rear unit A is a guide for partitioning the rear case 1, the substrate 3 fixed to the plurality of claws 1 a on the inner surface of the rear case 1, the storage portion of the AC adapter 26, and the AC adapter 26 and the substrate 3. A hole 9 mounted in the groove 1g, an antenna 15 (hereinafter referred to as ANT15), which is inserted into the hole 1h on the rear surface of the rear case 1 and then rotated and fixed and connected to the antenna terminal 18 on the substrate 3, and a hole. It is comprised by the cap 16 inserted in 1h. (The structure relating to the attachment of the ANT 15 and the cap 16 to the rear case 1 is described in detail in Japanese Patent Application No. 2000-237872.)
Second, the configuration of the front unit B will be described with reference to FIGS. The front unit B is fitted with a front case 5, a speaker 6, and a yoke 6 a of the speaker 6, and then rotated and locked by a claw 5 m on the inner surface of the front case 5 (hereinafter referred to as “SP Osae 17”). Consists of.
[0012]
Third, the configuration of the bottom unit D will be described with reference to FIGS. The bottom unit D includes a bottom case 13, a battery case 4 with a battery terminal (hereinafter referred to as a BAT case 4), and a bottom case 13 into which a protrusion 4 b slides along a guide groove 13 b of the bottom case 13. The battery cover 11 has a protrusion 11a that fits into the guide hole 13d.
[0013]
Next, assembly of the receiving apparatus of this embodiment will be described. First, the assembly of the main unit C (front unit A and rear unit B) will be described with reference to FIGS. The rear case 1 has a claw 1b on the back surface, and the front case 5 has a claw 5b corresponding to the claw 1b. The front case 5 has a hole 5g on the front surface, and the inner surface of the rear case 1 has a claw 1d corresponding to the hole 5g. One of the front unit A and the rear unit B is slid. For example, the front unit A is slid so that the claw 5b is fitted into the claw 1b and the claw 1d is held in the hole 5g. Can be assembled.
[0014]
Secondly, the mounting of the bottom unit D to the main unit C will be described with reference to FIGS. The upper surface of the front case 5 has a plurality of U-shaped claws 5h, and the inner surface of the bottom case 13 has a plurality of L-shaped claws 13c corresponding to the claws 5h. The rear case 1 has a plurality of protrusions 1i on the back surface, and the bottom case 13 has an L-shaped hole 13d corresponding to the protrusions 1i. The bottom unit C can be attached to the main unit C by sliding the bottom unit D with respect to the main unit C and fitting the claws 5h into the holes 13c and fitting the protrusions 1i into the holes 13d. Since the claw 13c and the hole 13d of the bottom case 13 are L-shaped, the mounting direction of the bottom unit D with respect to the main unit C is perpendicular to the mounting direction of the front unit A with respect to the rear unit B. The rear case 1 has a plurality of elastic claws 1e, and the bottom case 13 has square holes 13a corresponding to the elastic claws 1e. When the bottom unit D is inserted into the main unit C (the insertion direction is opposite to the mounting direction of the front unit A with respect to the rear unit B), the elastic claw 1e is bent on the inner surface of the bottom case 13. After the insertion, when the elastic claw 1e passes over the square hole 13a by moving the bottom unit D by changing the direction in which the bottom unit D is slid by 90 degrees, the restoring force of the elastic claw 1e is in its original state (the state is not bent). Trying to return. Due to this restoring force, the elastic claw 1e is locked to be caught in the square hole 13.
[0015]
The receiver of this embodiment can be assembled by assembling the main unit C and mounting the bottom unit D to the main unit C. Conversely, when disassembling the receiving apparatus of the present embodiment, each unit (front unit A, rear unit B, bottom unit D) can be slid in the same manner.
[0016]
Next, self-cleaning of the receiving apparatus of this embodiment and attachment / detachment of the OP board 7 will be described with reference to FIGS. When the bottom unit D is slid with respect to the main unit C, the terminals 21 and 22 on the BAT case 4 side move while contacting the power terminals 19 and 20 on the main unit C side. 19 and 20 are self-cleaned. The bottom case 13 has a storage portion for mounting the OP board 7 below the BAT case 4 and a plurality of guide grooves 13e that can be fixed after the OP board 7 is inserted by sliding. And ribs 13h. On the other hand, the rear case 1 has a claw 1a on which the substrate 3 can be mounted. By making the positions in the height direction of the claw 1a, the guide groove 13e, and the rib 13h the mounting positions in the height direction of the substrate 3 and the OP substrate 7 are made the same. As a result, it is possible to make it less susceptible to electromagnetic noise interference. Further, the bottom case 13 has a hole 13g for inserting the operation button 23 from the outside, and a guide groove 13f for sliding the button holder 24 for holding the button 23.
[0017]
As described above, in the receiving device mounting structure of this embodiment, the receiving device can be easily assembled and disassembled by sliding the unit. Therefore, it is possible to easily increase the production efficiency by replacing the substrate when the substrate is defective and attaching / detaching the OP substrate as necessary. Further, since it is not necessary to use a tool, the receiving device can be prevented from being damaged. Furthermore, since the fitting length is made large, the fitting portion can be prevented from coming off even if an excessive impact (for example, a drop impact) is applied.
[0018]
In the present embodiment, the mounting structure of the receiving apparatus has been described, but the present invention is not limited to this. In the same manner as the receiving device of this embodiment, the electronic devices other than the receiving device are enlarged so that the fitting lengths of the fitting claws of each unit can be sufficiently secured, and the units are slid without bending the fitting claws. By adopting the mounting structure, it is possible to increase the production efficiency and prevent the fitting portion from being detached even if an excessive impact (for example, a drop impact) is applied. Furthermore, it is possible to avoid scratching the electronic device.
[0019]
【The invention's effect】
According to the present invention, since a very simple assembly operation can be performed without using a tool, productivity can be greatly improved (in the case of mounting with a normal screw fixing method, it is screwed at 10 or more locations both inside and outside). In this case, it takes several minutes to assemble, but the electronic device having the mounting structure of the present invention can be assembled in tens of seconds). Compared to conventional screwless electronic devices, the locking claw and fitting claw are the same claw in the present invention, whereas in the present invention, the locking claw and fitting claw are the same claw. Therefore, it is possible to provide a mounting structure that is strong against a drop impact because the fitting length can be increased and assembly can be performed without bending the fitting claws. In addition, when responding to options, it has been necessary to remove the front case and add an OP board while flexing the claws of the rear case with a tool such as a screwdriver. An OP board can be added by simply removing the bottom unit by sliding it while pushing the claws, and the maintainability can be significantly improved. Furthermore, since the OP substrate is arranged horizontally with the substrate, there is an effect that it is difficult to receive interference of electromagnetic noise.
