It is the part bent so as to.

Thus, by providing the first fixing portion 41 and the second fixing portion 61 so as to overlap in the thickness direction, the dimension in the width direction can be reduced when the first fixing portion 41 and the second fixing portion 61 are installed. it can.
Thereby, it can suppress that the installation space which installs the 1st fixing | fixed part 41 and the 2nd fixing | fixed part 61 becomes large.

Since the step of connecting the first main body 35 and the second main body 36 can be eliminated by integrally forming the first main body 35 and the second main body 36 via the first fixing portion 41 and the second fixing portion 61, plus contact is made. The process for manufacturing the terminal 21 can be simplified.
Furthermore, since the first main body 35 and the second main body 36 are integrally formed via the first fixing portion 41 and the second fixing portion 61, the first main body 35 and the second main body 36 can be managed together. Management of the positive contact terminal 21 can be facilitated.

portions

41 and 61.
Accordingly, the first bending portion 51 is elastically deformed and the first bent piece 53D comes into contact with the first stopper piece 51C of the first bending portion 51. At the same time, the second bending portion 67 is elastically deformed and the second bent piece 69D comes into contact with the second stopper piece 67C of the second bending portion 67.

As shown in FIG. 7C, in the state where the first bent piece 53D is in contact with the first stopper piece 51C and the second bent piece 69D is in contact with the second stopper piece 67C, the battery pack 25 is Continue to move as shown by arrow C.
By continuously moving the battery pack 25 as indicated by the arrow C, the first elastic part 46 and the second elastic part 63 are elastically deformed.

The first elastic part 46 and the second elastic part 63 generate an elastic force that resists elastic deformation, so that the first bent piece 53D and the first stopper piece 51C can be brought into contact with each other at the designed contact pressure, and the first The two folded pieces 69D and the second stopper piece 67C can be contacted with each other at a designed contact pressure.
Thereby, the contact state of the plus contact pad 26 of the battery pack 25 can be reliably maintained at the first contact portion 48 and the second contact portion 66.

For example, in the embodiment, the electronic device 10 is exemplified as a mobile terminal, but the present invention is not limited thereto, and the electronic device 10 can be used as another device.

In the embodiment, the double contact terminal including the first main body 35 and the second main body 36 is illustrated as a plurality of main bodies. However, the present invention is not limited to this, and other plural main bodies such as three may be provided. Is possible.

Furthermore, in the embodiment, an example in which the first main body 35 and the second main body 36 are integrally formed in a state where the first main body 35 and the second main body 36 are connected by the connecting portion 37 has been described. It is also possible to form it separately.
When the first main body 35 and the second main body 36 are formed separately, the fixing

portions

41 and 61 of the

main bodies

35 and 36 can be fixed in a stacked state by caulking or the like.

In addition, the shape of the electronic device, the case, the contact terminal, the contact pad, the first main body, the second main body, the first fixing portion, the second fixing portion, the first elastic portion, the second contact portion, etc. used in the embodiment The configuration is not limited to that illustrated, but can be changed as appropriate.

This application is based on a Japanese patent application filed on May 31, 2011 (Japanese Patent Application No. 2011-122394), the contents of which are incorporated herein by reference.

INDUSTRIAL APPLICABILITY The present invention is suitable for application to an electronic device in which a battery housing part of a battery pack is provided in a housing and the contact terminal protrudes from the battery housing part so that the contact pad of the battery pack can contact the contact terminal. .
