Further, the engagement protrusion 23 extends in the direction in which the engagement protrusions 23 face each other, that is, in the width direction of the inserted mobile terminal device 10 and in the longitudinal direction of the mobile terminal device 10. 21 is an inverted triangular shape in front view protruding from the surface of 21.

  In the above configuration, the charging terminal 14 and the power feeding terminal 22 are connected in a state where the one side 12b of the second housing 12 is inserted into the support recess 21 of the cradle device 20, and the engaging protrusion 23 is engaged. Of the surfaces defining the groove 17, the upper surface 17 e is opposed to the back surface 17 d and the bottom surface 17 a extending along the overlapping surface 12 c of the second housing 12 and extends along the thickness direction of the second housing 12. It comes to contact.

  Further, among the wall surfaces that define the support recess 21, the front wall 24 that supports the overlapping surface 12 c side of the second housing 12 has a notch 24 a that allows the first housing 11 to pass therethrough. Yes. In the present embodiment, the cutout portion 24a has a semicircular shape in plan view that opens forward, and when the first housing 11 is rotated about the axis of the connecting portion 13, the front wall 24 and the first The housing 11 does not interfere.

  Further, in the present embodiment, the inner peripheral surface of the notch 24a protrudes radially inward of the notch 24a on the inner surface of the front wall 24 on the inner peripheral surface of the notch 24a. A support plate 24b extending along the line is formed. When one side 12b of the second casing 12 is inserted into the support recess 21 of the cradle device 20 and attached, the peripheral edge of the one side 12b of the second casing 12 on the side of the overlapping surface 12c contacts the support plate 24b. It is in contact with and supported by the front wall 24. Note that the thickness of the front wall 24 is equal to the thickness of the first housing 11, and the thickness of the support plate 24 b is thinner than the thickness of the front wall 24.

  In the illustrated example, the distal outer peripheral surface of the arc portion of the first housing 11 is on the inner peripheral surface of the notch portion 24a in a state where the closed mobile terminal device 10 is inserted into the support recess 21. In addition, the outer surface of the front wall 24 and the back surface 11e opposite to the overlapping surface 11c of the first housing 11 are substantially flush with each other, and the first and second housings 11 and 12 A support plate 24b is positioned between the overlapping surfaces 11c and 12c.

  In addition, when the mobile terminal device 10 is inserted into the support recess 21, the whole of the second housing 12 extending from both side surfaces 12 d and 12 d to the back surface 12 e on the one side 12 b is supported on the surface of the support recess 21. It is like that. Among these, the apparatus 10 is operated with the one side 12b of the second housing 12 inserted into the support recess 21 by the rear wall 25 of the support recess 21 that supports the one side 12b of the second housing 12 from the back surface 12e side. Even when a force to slide toward the back surface 12e in the thickness direction is applied to the one side 12b of the second housing 12 when it is closed from the open state, the movement can be prevented. ing.

  As described above, according to the mobile terminal device 10 and the charging connection structure according to the present embodiment, the size in the width direction on the one side 12b of the second housing 12 is the portion where the engagement groove 17 is formed. Since this portion is larger than the portion located closer to the end portion of the one side 12b, the engagement groove 17 is open toward the end portion of the one side 12b of the second housing 12, Even if the groove 17 does not extend from the end of the one side 12b toward the center of gravity of the housing 12, the support point of the engagement protrusion 23 in the second housing 12 and the center of gravity of the housing 12 The distance can be reduced.

  Therefore, when the second housing 12 is inserted into or removed from the support recess 21, the second housing 12 is guided in the inserting direction and the removing direction by the engagement of the engaging protrusion 23 and the engaging groove 17. The supporting force of the engaging protrusion 23 with respect to the second housing 12 can be improved while maintaining the forward / backward movement amount at the current level and preventing the handleability from being lowered. Furthermore, since it is not necessary to extend the engaging groove 17 from the end of the one side 12b toward the center of gravity of the housing 12, it is possible to prevent the appearance of the mobile terminal device 10 from being deteriorated. Furthermore, since the charging terminal 14 and the power feeding terminal 22 are connected in a state where the engaging groove 17 and the engaging protrusion 23 are engaged, the load acting on both the terminals 14 and 22 can be reduced. it can.

  Further, the charging terminal 14 is provided on both side surfaces 12d and 12d on one side 12b in the longitudinal direction of the second housing 12 adjacent to the engaging groove 17 in the thickness direction of the second housing 12. Therefore, the engagement groove 17 and the charging terminal 14 can be compactly disposed on both side surfaces 12d and 12d of the second housing 12, and the appearance of the mobile terminal device 10 can be improved.

  Furthermore, when the second housing 12 is supported from the back surface 12e side when inserted into the support recess 21, and the engagement groove 17 is formed on the back surface 12e side from the charging terminal 14, the insertion is performed. In the state where the second housing 12 is inclined toward the overlapping surface 12c side in the thickness direction, the engagement protrusion 23 is the second of the surfaces defining the engagement groove 17. By hooking (contacting) the back surface 17d extending in the direction along the overlapping surface 12c of the housing 12, the inclination of the second housing 12 can be prevented. Therefore, it is possible to prevent the power supply terminal 22 from being pressed and damaged by the surface defining the engagement groove 17 or the like.

  Furthermore, in the cradle device 20, since the upper end of the engaging projection 23 in the insertion direction is positioned above the upper end of the power supply terminal 22, when the second housing 12 is inserted into and removed from the support recess 21. In both cases, when the charging terminal 14 is in contact with the power supply terminal 22, the engaging protrusion 23 is engaged with the engaging groove 17. Therefore, when the terminals 14 and 22 are in contact with each other, the longitudinal direction of the mobile terminal device 10 can be made to coincide with the insertion direction and the like, and an uneven load or the like acts on the terminals 14 and 22. And can be prevented from being damaged.

  Further, the charging terminal 14 is provided at a position facing both side surfaces 12d and 12d of the one side 12b in the longitudinal direction of the second casing 12 in the width direction of the second casing 12, while the power feeding terminal 22 is supported. Since the surface of the concave portion 21 is provided so as to be able to protrude and retract by an elastic force, the charging terminal 14 of the inserted second housing 12 can be pressed in the width direction of the second housing 12. The support force for the two housings 12 can be further improved.

  Furthermore, the upper surface 17e extending in the thickness direction of the second housing 12 among the surfaces defining the engaging groove 17 is formed with the upper end of the engaging protrusion 23 when the second housing 12 is inserted into the support recess 21. Since the contact is made, the engaging projection 23 supports the second casing 12 via the upper surface 17e even when a lateral load in the width direction acts on the inserted second casing 12. Therefore, the supporting force with respect to the second housing 12 by the engagement protrusion 23 can be further improved.

  Further, the end portion of the one side 12b of the second housing 12 is an arc portion whose plan view is a convex arc shape toward the end portion of the one side 12b in the longitudinal direction. Is formed in this arc portion, the above-mentioned effects can be achieved easily and reliably.

  Further, when the second housing 12 is inserted into the support recess 21, the engagement protrusion 23 and the engagement groove 17 are engaged, and without charging the battery, the charging of the second housing 12 is interrupted. The mobile terminal device 10 can be opened and closed with the one side 12 b inserted into the support recess 21 of the cradle device 20.

  That is, when the first housing 11 is rotated about the axis of the connecting portion 13 to open the mobile terminal device 10, the one side 12 b of the second housing 12 is overlapped in the thickness direction in the thickness direction. Even when a force directed toward the 12c side is applied, the back surface 17d defining the engagement groove 17 is caught by the engagement protrusion 23 of the support recess 21, and the one side 12b of the second housing 12 is connected to the cradle device. It can prevent coming off from 20 support recessed parts 21.

  Thereby, it is possible to prevent the terminal 22 from being damaged by the rear surface 17d of the engagement groove 17 colliding with the power supply terminal 22 due to the disengagement. In particular, in the cradle device 20, since the power supply terminal 22 and the engagement protrusion 23 are provided in this order from the front wall 24 to the rear wall 25 of the support recess 21, such a collision can be prevented more reliably. can do.

  Further, in the present embodiment, since the support plate 24b is formed on the inner peripheral surface of the notch 24a, as described above, the support plate 24b is superimposed on the one side 12b of the second housing 12 in the thickness direction. Even when a force directed toward the surface 12 c is applied, the overlapping surface 12 c on the one side 12 b of the second housing 12 is caught on the inner surface of the support plate 24. Accordingly, it is possible to more reliably prevent the second casing 12 from being detached from the cradle device 20 described above.

The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
