DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dustproof cap, and more particularly, to a dustproof cap which is attached to a main body of an electronic device and closes an external connection terminal exposed on an outer surface of the main body.

[0002]

2. Description of the Related Art For example, electronic devices such as a portable telephone, a PHS telephone, a portable CD player, a digital camera, and a personal computer have a jack for inserting an earphone microphone, a connector for connecting to an external device, or a slot for attaching and detaching an external memory. Are provided in plurality. In particular, in recent years, portable electronic devices such as cellular phones and PHS telephones are provided with a terminal portion in which a connector for connecting a memory card is provided so that a large amount of information such as an image can be exchanged. Conventionally, in such a terminal portion, an openable dustproof cap having various shapes has been arranged for the purpose of preventing ingress of dust. FIG. 15 is a diagram showing an embodiment of a conventional dustproof cap employed in such a mobile phone. FIG.
Are dust caps 160a, 160 shown in FIG.
FIG. 13B is a diagram showing a state where b and 160c are mounted on a main body 150. FIG. 17 is a view showing another embodiment of a conventional dustproof cap. FIG. 18 is a view showing still another embodiment of a conventional dustproof cap.

As shown in FIG. 15, one embodiment of a conventional dustproof cap employed in a portable telephone is a plurality of jacks and connectors 4 arranged at an outer surface of a main body 150 of the portable telephone (three in FIG. 15). ) Terminal portions 154a, 15
4b and 154c.
b and 154c are attached to the main body 150 so as to cover each.

[0004] The dust caps 160a, 160b,
As shown in FIG. 15, an extension 160c extends in a thin plate shape and opens and closes the terminal 154, and the extension 1
A holding portion 162 is formed integrally with a holding portion 162 in which one end of 64 is bent at a substantially right angle to protrude in a T-shape. Further, the dustproof caps 160a, 160b, and 160c are provided with fixing portions 152a, 152b, and 152c formed by cutting out the main body 150.
Are provided, and the fixing portions 152a, 152b, and 152c have T
By fitting the letter-shaped holding portion 162, the terminal portions 154a, 154b, and 154c are fixed in a state of being closed as shown in FIG. Therefore, the dustproof cap 160
Are arranged for one terminal portion 154,
A plurality of terminals 154 are formed according to the number of the terminals 154 so that they can be individually opened and closed.

As another embodiment of the dustproof cap, as shown in FIG. 17, a boss 170a is provided to protrude into the main body 170 of the portable telephone, and is inserted into and fixed to the boss 170a. A thin plate-shaped holding portion 182,
An extension portion 184 is provided extending from the holding portion 182 to open and close a terminal portion (not shown). The dustproof cap 180 is attached to the boss 170a of the main body 170 by the holding portion 182.
The holes (not shown) are inserted and fixed to prevent the extension portion 184 from being pulled out of the main body 170 by being pulled.

Further, as shown in FIG. 18, a further embodiment of the dustproof cap has an extending portion 204 extending in a thin plate shape, and one end of the extending portion 204 is bent substantially at a right angle. The holding portion 202 that projects in a T-shape is integrally formed. This dust cap 200 is different from the dust cap shown in FIG. 15 in that a plurality of jacks 2 and connectors 4 (two in FIG. ) It is formed so as to close the arranged terminal portion (not shown). Thus, the dustproof cap 200 can be easily assembled and the number of manufacturing steps can be reduced. As described above, the conventional dustproof cap is formed in various shapes for the purpose of preventing dust from entering the terminal portion, and is formed so as to simultaneously obtain the effects of reducing the number of manufacturing steps and preventing dropout.

[0007]

However, in the conventional dustproof cap, for example, when the dustproof cap 160 shown in FIG.
As the number of parts increased, the number of parts to be mounted increased, and both the number of assembly steps and cost increased. Also, in the conventional dustproof cap, when the dustproof cap 180 shown in FIG. 17 is used, the holding portion 182 is formed large in order to obtain the effect of preventing the cap from coming off. The capacity increases, the number of mounting locations increases with the number of terminals (not shown), and the arrangement space in the main body 170 simply decreases. Furthermore, with the conventional dust cap,
When the dustproof cap 200 shown in FIG. 18 is used, when only the terminal (connector 4 shown in FIG. 18) close to the holding portion 202 is used, the unused terminal (jack 2) is also exposed. Not only does the effect of preventing the ingress of air from entering, but also the extension portion 204 becomes uselessly long and hinders, and the closing force for closing the terminal portion (not shown) in which the jack 2 and the connector 4 are arranged becomes weak. there were. An object of the present invention is to provide a low-cost dustproof cap that solves such problems, can be arranged in a small space, can individually open and close a plurality of terminals, and can reduce the number of assembly steps.

[0008]
