Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a small electronic device,
For example, the present invention relates to a locking structure of a lock button for fixing a battery pack detachably attached to a main body of a mobile phone to the main body, and an electronic device including the same.

[0002]

2. Description of the Related Art For example, a lock button of a portable telephone is, as shown in FIG.
And a hook claw 4 formed at the other end of the main body 2 and capable of being elastically deformed. Then, with the spring 5 mounted inside, the distal end of the hook 4 is pressed into the locking member 6 formed on the housing side of the mobile phone and is pushed in the direction of arrow A, so that the hook 4
Is opened in the direction of arrow A by elastic deformation, and assembled as shown in FIG.

When the force in the direction of the arrow A is released, a force in the direction of the arrow B acts on the main body 2 by the resisting force of the spring 5, the hook 3 engages with the locking member 5, and the lock button 1 is turned on. It is held in the housing. Then, the battery pack mounted on the housing of the mobile phone is fixed to the housing by the resistance of the spring 5.

[0004]

With such a configuration, as shown in FIG. 7, when a larger force acts in the direction of arrow B as compared with the coercive force of the spring 5, as shown in FIG. The hook 4 may be deformed in the direction of arrow A and come off the locking member 6.

[0005] In order to solve such a problem, when the bending strength of the hook 4 of the lock button 1 is improved,
A large force is required when assembling the lock button to the housing during the assembling work, which lowers the workability.

In view of the above-mentioned circumstances, an object of the present invention is to provide a lock button locking structure for preventing the lock button from being detached from the locking member without increasing the bending strength of the hook, and an electronic device having the same. To provide equipment.

[0007]

In order to achieve the above object, the invention described in claim 1 of the present application is slidably supported by an electronic device main body, and one end thereof is attached to the electronic device main body. The lock button is formed with a lock claw for fixing a component to the main body, and a hook claw formed on the other end for engaging with a locking member formed on the electronic device main body to prevent it from falling off. A locking structure, wherein a concave portion is formed on a surface of the locking member where the hooking claw contacts, and a concave portion of the locking member is fitted on a surface of the locking button where the hooking claw contacts the locking member. A convex portion is formed, and the convex portion formed on the hook of the lock button is fitted into the concave portion of the locking member to lock the lock button.

According to a second aspect of the present invention, the electronic device is provided with the lock button locking structure according to the first aspect.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 5 show a lock button according to the present invention and a mobile phone as an example of an electronic device using the lock button. FIG. 1 is an exploded perspective view of the mobile phone and a battery pack, and FIG. 3 is an exploded perspective view of the lock button, FIG. 3 is an enlarged perspective view of the lock button, FIG.
Is a plan sectional view showing a state before the lock button is assembled, and FIG. 5 is a plan sectional view showing a state after the lock button is assembled.

In FIGS. 1 and 2, reference numeral 7 denotes a front case. Reference numeral 8 denotes a rear case, which is formed with a concave portion 10 for fitting the battery accommodating portion 9 and the nail of the battery pack, and a lock button accommodating portion 11 for accommodating the lock button. The front case 7 and the rear case 8 form a housing of the mobile phone. As shown in FIGS. 4 and 5, the inside of the rear case 8 is provided with a recess 6a on the surface with which the locking claw of the lock button engages.
Are formed integrally with each other.

Reference numeral 12 denotes a battery pack having a convex portion 13 fitted in the concave portion 10 formed in the rear case 8 and a concave portion 14 fitted with a lock claw of a lock button.

1 is a lock button, as shown in FIG.
A main body 2, a lock claw 3 formed at one end of the main body 2 and fitted into a concave portion 14 of the battery pack 12, and a hook claw 4 formed at the other end of the main body 2 and engaged with the locking member 6.
And a projection 4a formed on the hook 4 and fitted into the recess 6a of the locking member 6 are integrally formed.
A spring 5 is mounted between the locking member 6 and the lock button 1.

When the lock button 1 is assembled to the rear case 8 with such a configuration, a spring 5 is mounted on the lock button 1 as shown in FIG. As shown in FIG. 4, the lock button 1 is pushed in the direction of arrow A. Then, the hook 4 is elastically deformed in the direction of arrow A, and is pushed to a position beyond the locking member 6 as shown in FIG. 5, and the lock button 1 is assembled to the rear case 8.

In such a state, when a large force in the direction of arrow B is applied to the lock button 1, the projection 4 a of the hook 4 of the lock button 1 fits into the recess 6 a of the locking member 6. The elastic deformation of the claw 4 in the direction of arrow A is restricted, and the lock button 1 can be prevented from coming off the rear case 8.

The lock button 1 from the rear case 8
Troubles such as the loss of the spring 5 due to the falling off can be eliminated.

According to the above-described embodiment, it is possible to reliably prevent the lock button from falling off from the electronic device without lowering the workability of the assembling work. Further, it is possible to prevent troubles caused by the drop of the lock button.

[0017]

As described above, according to the present invention, a lock slidably supported by an electronic device main body and having one end fixed to one end of the electronic device main body to the electronic device main body. A lock button locking structure in which a claw is formed and a hook claw is formed at the other end to engage with a locking member formed on the electronic device main body to prevent falling off,
A concave portion is formed on a surface of the locking member that comes into contact with the hook, and a convex portion that fits into the concave portion of the locking member is formed on a surface of the lock button that comes into contact with the locking member. Since the convex portion formed on the hook of the lock button is fitted into the concave portion of the lock member to lock the lock button, the electronic device can be mounted without lowering the workability of the assembly operation. It is possible to reliably prevent the lock button from falling off.
