The bottom plate 110 has a bottom plate top surface 111 and a bottom plate bottom surface 112 opposite to each other, and has, for example, two fixing holes 113, an assembly groove 114 and a mounting hole 117. The two fixing holes 113 and the mounting hole 117 penetrate through the top surface 111 of the bottom plate and the bottom surface 112 of the bottom plate. The assembling groove 114 is recessed inward from the top surface 111 of the bottom plate, and the bottom plate 110 protrudes, for example, with two fixing structures 115 located in the assembling groove 114. The side portion 120 may include, for example, two annular side walls 121. For example, the two annular side walls 121 stand on an edge 1110 of the bottom plate top surface 111 of the bottom plate 110 and are spaced apart from each other, so that the two annular side walls 121 and the bottom plate 110 jointly form a containing groove 140 and the bottom plate top surface 111 is located in the containing groove 140. In addition, the bottom plate 110 has, for example, a groove 116, and the groove 116 is located at the edge 1110 and between the two annular side walls 121.

The card firmware 130 includes a cantilever 131 and a card block 132. The cantilever 131 stands on the edge 1110 of the top surface 111 of the bottom plate and is located between the two annular side walls 121.

The first protrusion 203 protrudes from the first leg 202 along a first protrusion direction D2 perpendicular to the normal direction D1. In addition, the first protrusion 203 extends along the long axis direction D3 of the first leg 202 to increase the structural strength of the first leg 202.

Furthermore, in this embodiment, the first convex portion 203 is not in contact with the bottom surface 112 of the bottom plate 110, but the present invention is limited to this; in other embodiments, one side of the first convex portion can also abut On the bottom surface of the bottom plate of the bottom plate so that the bottom plate is clamped between the first convex portion and the first electrical contact portion.

The two first fixing portions 204 are respectively inserted into the two fixing holes 113, so that the first conductive member 200 is fixed to the base 100.

Please refer to FIG. 6 additionally. FIG. 6 is a partial enlarged view of the side cross-sectional view of the battery holder in FIG. 3; for example, the two buckle structure 205 extends from a side close to the first electrical contact portion 201 to away from the first electrical contact portion 201 The other side of the sexual contact portion 201 gradually approaches the bottom plate 110, that is to say, the two buckle structure 205 has a feature of bending downward and gradually approaching the bottom plate 110. In addition, as shown in FIG. 3, the two buckle structures 205 respectively form a line L with the central axis C of the accommodating groove 140, and the angle θ between the two lines L is, for example, less than 120 degrees.

The second conductive element 300 is fixed to the base 100 and includes, for example, a second electrical contact portion 301, a second leg portion 302, a second convex portion 303 and a second fixing portion 304.

The second leg portion 302 is connected to the second electrical contact portion 301. The second convex portion 303 is located at the second leg portion 302. Two opposite sides of the second fixing portion 304 are respectively connected to the second electrical contact portion 301 and the second leg portion 302.

The second electrical contact portion 301 is located in the accommodating groove 140 and includes, for example, an elastic arm 3010 and a bump 3011. The bump 3011 protrudes from the elastic arm 3010 and is located in the accommodating groove 140 and, for example, electrically contacts the bottom surface 32 of the battery 30. The elastic arm 3010 is connected to the second fixing portion 304 and disposed in the assembly groove 114. Please refer to FIG. 7 additionally. FIG. 7 is a partial enlarged view of the side cross-sectional view of the battery holder in FIG. 3; for example, the elastic arm 3010 extends from one side connected to the second fixing portion 304 to the other away from the second fixing portion 304 One side is gradually away from the bottom surface 112 of the bottom plate, that is, the elastic arm 3010 has the characteristic of being warped upward and away from the bottom surface 112 of the bottom plate.

The second leg portion 302 is disposed in the mounting hole 117 and passes through the bottom surface 111 and bottom surface 112 of the bottom plate 110. In addition, the second leg portion 302 extends outward along the normal direction D1 of the bottom surface 112 of the bottom plate.

The second protrusion 303 protrudes from the second leg 302 along a second protrusion direction D4 perpendicular to the normal direction D1. In addition, the second convex portion 303 extends along the long axis direction D5 of the second leg portion 302 to increase the structural strength of the second leg portion 302. Furthermore, the first protrusion direction D2 is opposite to the second protrusion direction D4, such that the first protrusion 203 and the second protrusion 303 face each other.

The second fixing portion 304 is, for example, riveted to the bottom plate 110 through the fixing structure 115 to be disposed in the assembling groove 114 to further fix the second conductive element 300 to the base 100.

In addition, as shown in FIG. 2, the side of the first leg portion 202 away from the first electrical contact portion 201 is fixed to the plate 20, and the side of the second leg portion 302 away from the second electrical contact portion 301 It is fixed to the plate 20 so that the electronic component 22 is located between the bottom surface 112 of the bottom plate 110 of the battery holder 10 and the plate 20.

Furthermore, referring to FIGS. 1 to 3 again, by pressing the bottom surface 32 of the battery 30 against the guiding inclined surface 1321 of the block 132, the battery 30 can be smoothly installed in the receiving groove 140. After the battery 30 is installed in the accommodating slot 140, the top surface 31 of the battery 30 will abut against the abutment surface 1320 of the block 132, and the two buckle structures 205 will buckle on the top surface 31 to form a three-point fixation. In addition, the downward bending feature of the two buckle structure 205 enables the battery 30 to be more firmly installed in the accommodating groove 140. Furthermore, after the battery 30 is installed in the accommodating groove 140, the upward warping feature of the elastic arm 3010 ensures that the bump 3011 on the elastic arm 3010 will electrically contact the bottom surface 32 of the battery 30.

Because the locking block 132 protrudes from the elastic cantilever 131, the toggled fastener 130 will give way due to the deformation of the cantilever 131, so that the battery 30 is separated from the contact surface 1320 of the locking block 132. Since the angle θ between the two connecting lines L of the two buckle structures 205 is less than 120 degrees, and the upwardly warped elastic arm 3010 will assist in pushing the battery 30 up, the battery 30 that is separated from the abutting surface 1320 is easier It can be further easily separated from the two buckle structure 205, so that the battery 30 can be detached from the accommodating slot 140.

Of course, the present invention is not limited to the arrangement of the fastener 130 and the two buckle structure 205; in other embodiments, the fastener and the two buckle structure may not be provided, and for example, an additional cover is used to remove the battery. It is fixed in the accommodating slot, or the battery is directly fitted to the side of the base.

According to the circuit board disclosed in the above embodiment, the first leg portion and the second leg portion extend outward along the normal direction of the bottom surface of the bottom plate, and the first convex portion and the second convex portion are respectively along the first leg The long axis direction of the second leg portion and the long axis direction of the second leg portion extend, so the first leg portion of the first conductive member and the second leg portion of the second conductive member have sufficient structural strength to stabilize the base The seat frame is high, so that the electronic components can be arranged between the bottom surface of the bottom plate and the board, thereby increasing the space utilization rate on the board. In this way, the battery holder can take into account the space utilization rate on the board and the stability of the base on the board.

Although the present invention is disclosed in the foregoing embodiments as described above, it is not intended to limit the present invention. Anyone familiar with similar art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, this The scope of patent protection for inventions shall be determined by the scope of patent applications attached to this specification.
