  The rear case 2b is provided with a battery housing portion 21 that is covered with a battery 100 with a lid, which will be described later. The battery accommodating part 21 accommodates the battery part 110 of the battery with lid 100 and is covered with the lid part 120 by mounting the battery with lid 100 on the rear case 2b. A magnetic antenna 81 for non-contact communication is disposed in the vicinity of the battery housing part 21. The magnetic antenna 81 is disposed on the outer periphery of the battery housing part 21. In the present embodiment, the magnetic antenna 81 is disposed on the outer peripheral portion of the battery housing portion 21. However, the present invention is not limited to this. For example, you may arrange | position to the lid part (covering member) 120 and may arrange | position to either of the batteries 100 with a lid.

  As shown in FIG. 4, the battery with lid 100 includes a battery unit 110 and a lid unit 120. Moreover, the battery 100 with a lid includes a locking claw 101 that locks into a recessed locked portion in the battery housing portion 21 formed on one end side, and a hole-like shape in the battery housing portion 21 formed on the other end side. And an engaging portion 102 that engages with the engaged portion.

  As shown in FIG. 5, the battery unit 110 includes a battery pack 111 formed in a substantially rectangular shape, a conductive unit 112 that conducts to the circuit board 70 and the like, and a fitting unit that is disposed so that the conductive unit 112 is exposed. 113. The fitting portion 113 is provided at the end of the battery pack 111 and is disposed so that the conductive portion 112 provided at the end of the battery pack 111 is exposed. Further, the conductive portion 112 and the fitting portion 113 are arranged on the non-joint surface 114 side opposite to the joint surface 115 joined to the lid portion 120.

  The lid portion 120 has a first surface 121 on which the battery unit 110 is disposed, and a second surface 122 that constitutes a part of the outer surface of the operation unit side body 2 by being attached to the rear case 2b. .

  As shown in FIGS. 6 and 7, a plurality of recesses 125 are formed on the first surface 121 of the lid portion 120. The recess 125 is formed by punching out the lid portion 120 from the first surface 121 toward the second surface 122 in a substantially cylindrical shape. The concave portions 125 are arranged at predetermined intervals in the width direction of the lid portion 120 and are also provided at predetermined intervals in the longitudinal direction.

  The lid portion 120 includes a pair of side wall portions 124a and 124a provided at both ends in the width direction, an upper wall portion 124b orthogonal to the side wall portions 124a and 124a, and a side wall portion 124a and 124a. It has the lower wall part 124c facing the wall part 124b.

  Each of the side wall parts 124 a and 124 a and the upper wall part 124 b is formed such that the wall height is higher than the thickness of the battery part 110 in a state where the battery part 110 is joined. Specifically, when the low pressure molding resin is poured between the first surface 121 of the lid portion 120 and the joining surface 115 of the battery portion 110 and the low pressure molding is performed, the non-joint surface 114 and the side wall of the battery portion 110 are formed. The top surface of the top wall portion and the top wall portion are the same surface, and one surface of the lidded battery 100 is formed in a substantially flat shape. In addition, the lower wall part 124c is formed so that the fitting part 113 provided in the battery part 110 can be fitted.

  In addition, a resin mold part 130 that joins the lid part 120 and the battery part 110 is provided between the lid part 120 and the battery part 110. The resin mold part 130 is provided between the first surface 121 of the lid part 120 and the joint surface 115 of the battery part 110, and between each wall part of the lid part 120 and the side surface 116 of the battery part 110.

  When the resin is poured into the first surface 121 of the lid portion 120 with the battery portion 110 disposed, the poured resin enters between the joint surface 115 of the battery portion 110 and the first surface 121 of the lid portion 120. . Then, the resin that has flowed onto the first surface 121 enters the recess 125 formed on the first surface 121. When the poured resin is cured, the battery part 110 and the lid part 120 are joined, and the resin mold part 130 is formed.

  As shown in FIGS. 6B and 7B, the resin cured in the recess 125 adheres to the lid portion 120 on the side wall in addition to the bottom in the recess 125. Thereby, in the recessed part 125, an adhesion area increases. Further, when the resin adheres to the side wall, for example, even when a force is applied in a direction in which the resin peels (a direction orthogonal to the first surface of the recess 125), the resin is in a direction opposite to the peeling direction. Since a force in the direction of shearing is generated, the adhesive strength can be increased. Note that the direction of shearing the resin includes, for example, a direction substantially parallel to the side wall of the recess 125.

  Next, an operation of attaching the above-described battery with lid 100 to the rear case 2b will be described. FIG. 11 is a schematic diagram showing a state in which the lidded battery 100 is attached to the display unit side body 3 of the mobile phone 1. FIG. 12 is a schematic diagram showing a state in which the locking claw 101 provided on one side of the battery with lid 100 is unlocked. FIG. 13 is a schematic diagram illustrating a state in which the battery 100 with the lid is removed from the display unit side body 3.

  As shown in FIG. 11, the battery with lid 100 is mounted so as to be integrated with the rear case 2 b of the operation unit side body 2. Specifically, the battery 100 with a lid engages an engaging portion 102 provided on one end side in the longitudinal direction of the battery 100 with a lid with a hole-like engaged portion in the battery housing portion 21, and in the longitudinal direction. The engaging claw 101 provided on the other end side is mounted in a state of being engaged with the recessed engaged portion 22 in the battery accommodating portion 21. In the battery with lid 100 thus mounted, the second surface 122 of the lid portion 120 constitutes the outer surface of the rear case 2b, and is attached integrally with the rear case 2b.

  When removing the battery with lid 100 attached to the rear case 2b, first, the latching of the latching claw 101 of the battery with lid 100 and the locked portion 22 of the rear case 2b is released. Specifically, the locking claw 101 and the locked portion 22 are unlocked by pushing the locking claw 101 into the locked portion side 22 by a predetermined amount.

  Furthermore, as shown in FIG. 12, the battery 100 with a lid in a state in which the locking claw 101 is released is pulled out upward. At this time, a force is applied to pull up the lid portion 120, and thus a force that separates the lid portion 120 and the battery portion 110 is applied. Furthermore, the locking claw 101 side of the lid portion 120 tends to warp and deform upward by being pulled upward, whereas the battery portion 110 has a predetermined strength and is not easily deformed. Thereby, a high load is applied to the joint surface between the lid portion 120 and the battery portion 110 in the vicinity of the locking claw 101. That is, a force that releases the bonding between the lid 120 and the battery unit 110 is generated on the bonding surface between the lid 120 that is to be deformed and the battery 110 that is less deformed. Specifically, a force for releasing the bonding is applied to the bonding surface between the lid portion 120 and the resin mold portion 130 in a direction orthogonal to the bonding surface.

  On the other hand, since the recess 125 has a recess bonding surface (side surface of the substantially cylindrical recess) formed substantially parallel to the direction in which this force acts, in addition to the bonding strength at the bonding surface, the recess bonding surface and the resin mold portion The force in the shear direction generated during the period is added to the adhesive strength. As a result, the bonding strength between the lid part 120 and the battery part 110 can be further increased.

  Furthermore, the battery 100 with a lid is removed by releasing the engagement between the engagement portion 102 provided on one end side in the longitudinal direction of the battery 100 with a lid and the battery housing portion 21 (see FIG. 13).

  In addition, when attaching the battery 100 with a lid, it becomes possible to attach by performing an operation opposite to the above-described action.

  As described above, the battery with lid 100 in which the battery unit 110 and the lid unit 120 are joined is provided with a plurality of concave portions 125 formed in a substantially cylindrical shape on the inner surface of the lid unit, whereby the first surface of the lid unit 120 is provided. Since the resin poured between the bonding surface of the battery unit 110 and the bonding surface of the battery unit 110 enters the concave portion 125, the concave portion in addition to the adhesive force by the first surface 121 of the lid portion 120 even when stress is applied in the peeling direction. Since an adhesive force due to a shearing force generated in a direction opposite to the peeling direction is applied to the side wall forming 125, the battery part 110 is difficult to peel from the lid part 120 in the recess 125. In other words, the resin mold part 130 can increase the adhesive strength.

  Further, by providing a plurality of cylindrical recesses 125 on the first surface 121 of the lid portion 120, the adhesion area of the first surface 121 of the resin can be increased. Specifically, when the resin enters the recess 125 formed in the first surface 121, the resin is bonded to each of the insides of the recess 125. That is, it joins with the bottom part and side wall of the recessed part 125, respectively. Thereby, compared with the case where the recessed part 125 is not provided, the adhesion area increases by the amount of the peripheral wall of the recessed part 125. And it becomes possible to increase adhesive strength by increasing an adhesion area.

  In the present embodiment, the recess 125 is formed in a circular shape on the first surface 121. However, the present invention is not limited to this. For example, you may form in polygonal shapes, such as a triangle and a rectangle. That is, the recess 125 may be formed in a shape such as a triangular prism or a quadrangular prism. Further, not only a plurality of the concave portions 125 but also a groove portion may be provided on the first surface 121. Further, the concave portion 125 may be formed in a hole shape that penetrates the lid portion 120.

Another embodiment of the present invention will be described with reference to FIGS. FIG. 8A is a YY cross-sectional view of a lidded battery 100A including a hole portion 125A having a large opening area on the second surface 122 side while penetrating the lid portion 120, and FIG. It is the elements on larger scale of a). 9A is a YY cross-sectional view of a battery 100B with a lid that includes a flange hole portion 125B that penetrates the lid portion 120 and has a flange portion formed on the second surface 122 side, and FIG. It is the elements on larger scale of (a). FIG. 10A is a YY sectional view of the lidded battery 100C in which the hole portion 125C penetrates the lid portion 120 and the resin protrudes to the second surface 122 side of the lid portion 120C. (A) is the elements on larger scale, (c) is the perspective view which looked at the battery 100C with a lid from the 2nd surface side.

  In the following embodiments, parts that are not particularly described are the same as those in the above-described embodiments, and the same reference numerals are given to the numbers given in the drawings when they are the same as those in the above-described embodiments.

  As shown in FIGS. 8A and 8B, the lidded battery 100A allows the first surface 121 and the second surface 122 of the lid portion 120A to communicate with each other and has an opening area on the first surface 121. A hole 125A that is smaller than the opening area of the second surface 122 may be formed.

  As described above, by providing the hole 125A whose opening area in the first surface 121 is smaller than the opening area in the second surface 122, it is possible to make it difficult for the resin to be pulled out from the hole 125A. In addition, the bonding area between the resin and the lid portion 120A can be increased. Thereby, compared with the case where the recessed part 125 is formed, it becomes possible to make joint strength stronger and it becomes possible to suppress that the battery part 110 peels from the lid part 120A.

  The battery with lid 100A may have the entire recess 125 as a hole 125A. However, when the battery with lid 100A is attached or detached, the latching claw of the battery with lid 100A easily peels off from the lid 120A. It is preferable to be provided on the 101 side and the engaging portion 102 side.

  9A and 9B, the battery with lid 100B allows the first surface 121 and the second surface 122 of the lid portion 120B to communicate with each other and the opening on the first surface 121. You may form the flange hole part 125B which provided the flange part 126 which has an opening area larger than an area in the 2nd surface 122 side.

  As described above, by providing the flange hole portion 125B in the lid portion 120B, the flange portion 126 of the flange hole portion 125B is locked to the lid portion 120 even when stress is applied in the peeling direction of the battery portion 110. It is possible to make it difficult for the resin to be pulled out from the flange hole portion 125B. In addition, the bonding area between the resin and the lid portion 120B can be increased. Thereby, compared with the case where the recessed part 125 is formed, it becomes possible to make joint strength stronger and it becomes possible to suppress that the battery part 110 peels from the lid part 120B.

  The battery 100B with a lid may have the entire recess 125 as a flange hole 125B, but the battery 100B with a lid is a part where the battery part 110 is easily peeled off from the lid part 120B when the battery 100B with a lid is attached or detached. It is preferable to be provided on the locking claw 101 side and the engaging portion 102 side.

  Also, as shown in FIGS. 10A to 10C, the battery with lid 100C is provided with a hole portion 125C in which the first surface 121 and the second surface 122 of the lid portion 120C are communicated with each other, and a resin. A protrusion 130 </ b> C that protrudes toward the second surface 122 may be formed by the resin poured into the mold part 130.

  For example, it is possible to provide a function as a cushion for preventing the cellular phone 1 from being damaged by contacting the receiver when using electronic money performed by non-contact communication. In addition, for example, when the user holds the mobile phone 1 or puts the mobile phone 1 on an inclined portion, it can be used as a slip stopper. In this case, a polyamide resin is preferably used as the resin used for low-pressure molding. The polyamide resin has a characteristic that it is softer than other resins such as PC resin (polycarbonate resin) and ABS resin (acrylonitrile / butadiene / styrene resin) even when cured. It becomes possible to act as a buffer part in the lid part 120C.

  In the battery with lid 100C, the protruding portion 130C may be formed in the vicinity of the magnetic antenna 81 that communicates with an external device in order to perform non-contact communication in the hole portion 125C. The protrusion 130C may be formed on the surface.

  Further, when the battery 100C with a lid is attached and detached, the above-described hole 125A or the flange hole 125B may be provided on the side of the latching claw 101 of the battery 100C with the lid that the battery part 110 is easily detached from the lid part 120C. Good.
