Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal for a portable electronic device having a detachable portion, and more particularly to a seal plate for a portable electronic device which seals a contact surface between the detachable portion and the device body.

[0002]

2. Description of the Related Art In portable electronic devices, a battery pack is used to supply power to the portable electronic device main body. Until now, portable electronic devices have not been considered for use outdoors in the case of rain, or have no means for properly attaching and detaching the battery pack and the electric appliance body, which are easily removable. In particular,
Although there is a contact surface between the attachment / detachment portion such as the battery pack and the device body when it is attached, there is no one that can simply and easily attach / detach the contact surface. Therefore, in the conventional portable electronic device, the seal between the portable electronic device main body and the battery pack is not particularly considered, and the portable electronic device does not have a splash-proof structure.

[0003]

In recent years, the demands of customers have been diversified, and a portable electronic device is required to have a splash-proof function so that it can be used outdoors without trouble regardless of rain.

In view of the above situation, the present invention provides a seal plate capable of sealing the surface of a device such as an electronic device main body and a battery pack that requires simple attachment / detachment.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a seal plate provided on a contact surface between a device body and a detachable portion of a portable electronic device having a detachable portion, the portion being along a seal line. The feature is that the required amount is raised to form a step.

[0006]

When the attachment / detachment portion is attached to the equipment body, the seal plate provided on the abutment surface between the equipment body and the attachment / detachment portion only contacts the abutted surface along the seal line. Contact and deform the required amount to seal the boundary between the device body and the detachable part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a telephone body of a portable telephone which is one of portable electronic devices, and in FIGS. 2 and 3, 2 denotes a battery pack mounted on the telephone body 1. A case where the present invention is applied to a mobile phone will be described.

An interface 3 between the phone body 1 and the battery pack 2 appears on the surface 4 of the boundary between the phone body 1 and the battery pack 2 (the surface of the mobile phone with the battery pack 2 attached to the phone body 1). The required step is formed with the surface including the boundary line,
A guide rail 5 is formed at a boundary position between the united surface 3 and the boundary surface 4. The guide rail 5 has a partial cutout near the side (upper side) from which the antenna 22 projects,
Is continuous over substantially the entire length of the united surface 3 in the vertical direction,
It is a drip-proof wall that faces the boundary surface 4.

Further, the guide rail 5 is provided with a notch portion 7 for introducing an engagement protrusion 6 of the battery pack 2 which will be described later and an engagement groove 8 which is continuous with the notch portion 7 and extends in parallel with the boundary surface 4. Has been formed.

Guide grooves 9 into which the guide rails 5 are fitted are formed on both sides of the battery pack 2, and a peripheral surface of the battery pack 2 is defined by a united surface 10 that contacts the united surface 3 of the telephone body 1. A peripheral wall 11 having a height corresponding to the step of the united surface 3 is formed. The peripheral wall 11 conforms to the boundary surface 4, the side wall portion facing the guide groove 9 is provided with the above-mentioned engaging projection 6, and the bottom wall portion of the peripheral wall 11 has a semicircular cutout portion. 12 are formed. The notch 12 is adapted to abut on the lower surface 13 of the united surface 3, and when the battery pack 2 is mounted on the telephone body 1, the notch 12 is closed by the lower surface 13. It is supposed to be.

A seal plate 14 made of a highly elastic material such as silicone rubber, urethane rubber, plastic elastomer, or butyl rubber is attached to the upper end surface of the battery pack 2, and a water-repellent fiber cloth is applied to the bottom surface of the guide groove 9. A water repellent sheet 15 made of cloth or the like in which a water repellent material is impregnated into a non-woven fabric is attached.

The seal plate 14 will be described with reference to FIGS.

The upper end surface of the battery pack 2 is composed of a vertical surface and an inclined surface, and the seal plate 14 has a vertical surface 14a and an inclined surface 14b so that the upper end surface of the battery pack 2 is completely adhered. . Further, since the sealing property depends on the magnitude of the surface pressure, the seal plate 14 is shaped so as to secure the surface pressure at a required value and deform the seal plate 14 properly.

That is, the seal portion 18 along the seal line of the vertical surface 14a and the peripheral edge 19 along the seal line of the inclined surface 14b are raised steps, respectively, and the battery pack 2 is attached to the telephone body 1 When the upper end surface of the battery pack 2 is in contact with the contacted surface of the telephone main body 1, the seal portion 18 and the peripheral edge 19 are in contact with each other so that the surface pressure becomes a required value.

Further, a protrusion 20 is formed substantially in the center of the seal plate 14, and the protrusion 20 fits into a recess 21 formed in the contact surface on the telephone body 1 side to close the recess.

Reference numeral 16 in FIG. 3 denotes an engaging claw that engages with an engaging hook (not shown) on the side of the telephone body 1, and reference numeral 17 in FIG.
A release button for releasing the engagement between the engagement hook and the engagement claw 16.

When the battery pack 2 of FIG. 2 is mounted on the telephone body 1 of FIG. 1, the engaging projection 6 is aligned with the cutout portion 7 to bring the telephone body 1 and the battery pack 2 into close contact with each other, and the battery pack 2 is attached. Slide up. The engagement protrusion 6 is fitted into and slides in the engagement groove 8, the engagement claw 16 engages with an engagement hook (not shown), and the battery pack 2 is fixedly attached to the telephone body 1. As described above, the notch 12 contacts the lower surface 13 and is closed.

The seal plate 14 is interposed between the upper end surface of the battery pack 2 and the contacted surface of the telephone body 1.
The seal plate 14 is deformed by a predetermined amount by the engagement of the engagement claw 16 and an engagement hook (not shown), and the seal portion 18 and the peripheral edge 19 are deformed by a required amount, and the upper end surface of the battery pack 2 and the telephone body 1 are connected.
The contact surface of the battery pack 2 is hermetically sealed, and the restoring force of the seal plate 14 prevents rattling of the battery pack 2. Furthermore,
Since the seal plate 18 has the seal portion 18 and the peripheral edge 19 and the contact area is limited, a sufficient sealing effect can be exhibited without using a strong fixing means such as a screw.

A water repellent sheet 15 is interposed between the upper surface of the guide rail 5 and the bottom surface of the guide groove 9. The water repellent sheet 15 allows smooth sliding of the battery pack 2 with respect to the telephone body 1, and water penetrates through a slight gap between the guide rail 5 and the water repellent sheet 15 due to the surface tension of the water repellent sheet 15. Suppress the.

The water soaked from the boundary surface 4 between the telephone body 1 and the battery pack 2 is prevented from entering the inside by the seal plate 14 and the water repellent sheet 15. Further, the water soaked flows down along the boundary surface and is extruded to the outside from the notch 12, so that it does not cross over the step of the united surface 3 and enter the inside.

Since the guide rail 5 is continuously formed, the guide rail 5 functions as a drip-proof wall. The present inventor has confirmed by experiments that the guide rail 5 is partially cut away, but the function of the guide rail 5 as a drip-proof wall is not impaired.

When the battery pack 2 is attached to the telephone body 1 and further charging is continued after the battery pack 2 is rapidly charged, gas is generated. The generated gas is generated on the lower surface 13 and the peripheral wall 11. The notch 12 through the minute gap of
More volatilized to the outside.

Needless to say, the seal portion 18 and the peripheral edge 19 are formed not only on the peripheral edge of the seal plate 14 itself but also on the boundary portion to be sealed, and according to the present invention. It is needless to say that the present invention can be applied to a contact surface to be sealed of a portable electronic device having a detachable portion other than a mobile phone.

[0025]

As described above, according to the present invention, the contact surface to be sealed can be easily sealed, and the portable electronic device having the detachable portion can realize the splash-proof function. Exert the effect.
