Description

Electrical connector and electronic device {ELECTRIC CONNECTOR AND ELECTRONIC DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates generally to an electrical connector and an electronic device including the electrical connector, and more specifically, is attached to the housing of the electronic device by being inserted into a fitting hole formed in the housing of the electronic device, and The present invention relates to an electrical connector capable of liquid-tight sealing a space between a device and an electronic device including the electrical connector.

Conventionally, electrical connectors have been used to electrically connect electronic devices and other electronic devices. A receptacle connector that is mounted on a circuit board installed in the housing of the electronic device and exposed to the outside of the electronic device through a through hole provided in the housing of the electronic device in order to obtain an electrical connection between the electronic device and other electronic devices And, two types of electrical connectors, such as plug connectors for insertion into the outlet of the receptacle connector, are used in combination.

As such an electronic connector, a universal serial bus (USB) connector or the like is widely used. For example, Patent Document 1 discloses a receptacle connector, wherein the receptacle connector is mounted on a circuit board installed in a housing of an electronic device (eg, PC, game console, mobile phone, smartphone), and the housing of the electronic device The outlet of the receptacle connector is exposed to the outside of the electronic device through the through hole provided in the electronic device. By inserting a corresponding plug connector into the outlet of the receptacle connector exposed to the outside of the electronic device, it is possible to provide an electrical connection between the electronic device and another electronic device.

Also in portable devices such as mobile phones and smart phones, the receptacle connectors as described above are widely used. When a user carries such a portable device, it is assumed that the portable device gets wet due to rain, or a situation in which the portable device is accidentally dropped into the water. In such a situation, in order to prevent water from entering the housing of the electronic device through the gap between the receptacle connector and the housing of the electronic device, the distal end of the outer periphery of the shell 810 as shown in FIGS. 1 and 2 An electrical connector 800 having a waterproof function having a waterproof sealing member (a gasket made of an elastic material, etc.) 820 provided in the wall is known (see, for example, Patent Document 2).

As shown in FIG. 2, the electrical connector 800 is inserted into the fitting hole 910 formed in the housing 900 of the electronic device, and is attached to the housing 900 of the electronic device. When the electrical connector 800 is attached to the housing 900 of the electronic device, the electrical connector 800 and the electronic device are formed by a waterproof seal member 820 installed at the distal end of the outer periphery of the shell 810 of the electrical connector 800. The gap between the housing 900 and the liquid-tight is sealed. With this configuration, water is prevented from entering the interior of the housing 900 of the electronic device through the gap between the electrical connector 800 and the housing 900 of the electronic device.

However, since the waterproof sealing member 820 is made of a soft resin material, a silicone material, or an elastic material such as rubber, the strength is low. Therefore, when inserting the electrical connector 800 into the fitting hole 910 of the housing 900 of the electronic device, the entire outer periphery of the waterproof seal member 820 is inserted into the fitting hole 910 of the housing 900 of the electronic device. ), it is inserted while being in contact with the entire inner surface of the waterproof seal member 820 and the inner surface of the fitting hole 910, since it is difficult to equalize the occurrence of frictional force due to the misalignment of the insertion angle, etc. Twisting, twisting, and curling of the waterproof seal member 820 are likely to occur. When such twisting, twisting, or curling of the waterproof sealing member 820 occurs, the waterproof function by the electric connector 800 cannot be provided.

For this problem, a method of directly molding the waterproof seal member 820 on the outer periphery of the shell 810 of the electrical connector 800 (eg, LIM: Liquid Injection Molding) is sometimes used. However, such a method increases the manufacturing time of the electrical connector 800, consequently deteriorates the productivity of the electrical connector 800, and has a problem that the manufacturing cost of the electrical connector 800 increases.
