Conventionally, a connector such as a micro USB connector is directly mounted on a substrate in consideration of ease of electrical control.
For this reason, it has been difficult to firmly fix the connector and its periphery due to the positional deviation of mounting on the board and concerns about the assembly method of the product.
In particular, a connector such as a micro USB connector that is always provided in a mobile terminal or the like is used for various purposes such as charging, connection with other devices, and writing and reading of information inside. Therefore, the connector is frequently used and there is a risk of receiving a dynamic or static load from the outside during connection.

Conventionally, as shown in FIG. 5, a connector device 100 in which a connector main body 101 is directly mounted on a rigid board 102 has been proposed.

Therefore, the connector device 100 may not be able to use the connector main body 101 and the rigid board 102.

Further, as shown in FIG. 6, in the connector device 100, the connector main body 101 directly mounted on the rigid board 102 is arranged in the first casing 111 arranged in the upper part in the figure and in the lower part in the figure. It is sandwiched and fixed between the second housing 112.
Therefore, the connector device 100 directly receives a load applied to the first casing 111 or the second casing 112.
Therefore, the connector device 100 may not be able to use the connector main body 101.

On the other hand, the connector device described in Patent Document 1 can achieve reliable shielding of electromagnetic wave noise without increasing the mounting accuracy of the connector.
However, in the connector device described in Patent Document 1, although the circuit unit and the connector are connected by a flexible connection line, the circuit unit and the connector are rigidly fixed to the housing body and the rear panel having an integral structure. Yes.
Therefore, in the connector device described in Patent Document 1, when a load is applied to the housing main body or the rear panel, the load is directly applied to the circuit unit and the connector, so that the circuit unit and the connector are damaged. There was a fear.

On the other hand, in the connector device described in Patent Document 2, the auxiliary connector is electrically connected to the internal connector, and the elastic member electrically connects the internal connector and the electronic circuit. By having the elastic member, the impact force from the outside applied to the connector connecting portion can be reduced to less than about 10%.
However, in the connector device described in Patent Document 2, since the connector connecting portion is composed of an internal connector and an auxiliary connector, the number of parts increases, and a large number of man-hours are required for managing a plurality of parts at the time of manufacture. There was a problem of increasing man-hours as necessary.

The connector device 10 is used by being mounted on a mobile phone.

 The rigid substrate 11 is made of glass epoxy, a plurality of electrical components 15 are mounted on the lower surface, and a sheet metal panel 16 having an electromagnetic shielding function is attached to the upper surface.

As shown in FIG. 2, the flexible printed circuit board 12 is made of a flexible wiring body and is bent into a substantially S shape. The flexible printed circuit board 12 has one end bent in a substantially S shape and a base end electrically connected to a printed circuit (not shown) provided on the rigid board 11, and the other end connected to the connector main body 14. A tip portion electrically connected to a built-in connector terminal (not shown) is formed.
The base end portion of the flexible printed board 12 is a rigid board connecting portion 17, and the distal end portion of the flexible printed board 12 is a connector main body connecting portion 18.
The flexible printed circuit board 12 has a bent portion 19 that is bent in a substantially S shape and can be elastically deformed between the rigid board connecting portion 17 and the connector main body connecting portion 18.

The flexible printed circuit board 12 holds the connector main body 14 in a floating state with a predetermined distance L1 above the rigid board 11 by bending the bent portion 19 into a substantially S shape. .
Further, the flexible printed circuit board 12 is elastically deformed when a stress is applied to the connector main body 14 in a direction parallel to the rigid circuit board 11 because the bent portion 19 is bent in a substantially S shape.

Further, the flexible printed circuit board 12 is elastically deformed by the stress from the connector body 14 toward the rigid board 11 and the stress from the rigid board 11 toward the connector body 14 because the bent portion 19 is bent into a substantially S shape. .
