[0089] In some embodiments, the limiting portion 26 can include a blocking portion 262, which is protruded on the side of the base 261 away from the bottom plate 21. The blocking portion 262 has a spacing with the inner wall of the side wall 22, so that the space between the side of the blocking portion 262 facing the inner wall of the side wall 22, the side of the base 261 away from the bottom plate 21 and the inner wall of the side wall 22 forms the above-mentioned limiting space. The second end plate 33 is clamped into the limiting space, one side of the second end plate 33 abuts against the base 261, and the other side abuts against the blocking portion 262, which can prevent the second end plate 33 from being pulled out of the limiting space, and improve the connection stability of the terminal plate 3 and the bottom plate 21.

[0090] In some embodiments, the abutment portion 262 can include a first section 262a and a second section 262b. The first section 262a is connected to the base 261 at one end and extends towards the bottom plate 21 to form the first section 262a. The other end of the first section 262a is connected to the second section 262b, which can be inclined, so that the second end plate 33 can enter the limiting space along the second section 262b. The second section 262b provides a guide for the second end plate 33 to facilitate its sliding into the limiting space. In the direction from the bottom plate 21 to the back plate 1, the distance between the second section 262b and the inner wall of the side wall 22 gradually increases, so that the second section 262b forms an inclined slope.

[0091] In some embodiments, the base 261 and the abutment portion 262 are integrally formed to form the limiting portion 26. The limiting portion 26 can be fixed to the bottom plate 21 by bonding or screwing, or can be integrally formed with the bottom plate 21. The interior of the base 261 and the abutment portion 262 can be hollow to reduce the material cost of the limiting portion 26.

[0092] In some embodiments, the bottom plate 21 can also be provided with a plurality of protrusions 27 on the side facing the back plate 1. The plurality of protrusions 27 are arranged in the same direction as the at least two limiting portions 26, and the side of the second end plate 33 facing away from the back plate 1 abuts against the protrusions 27, so that the second end plate 33 is indirectly abutted against the bottom plate 21 by the protrusions 27. If the second end plate 33 is directly abutted against the bottom plate 21, the contact area is large, and the flatness requirement of the bottom plate 21 is high. If the flatness of the bottom plate 21 is slightly not up to standard, it may cause the second end plate 33 to be misaligned. Therefore, by arranging a plurality of spaced protrusions 27, the second end plate 33 is abutted against the plurality of protrusions 27, so that the second end plate 33 is in contact, reducing the impact of the flatness of the bottom plate 21 not meeting the standard on the installation of the second end plate. At the same time, the plurality of protrusions 27 can also increase the structural strength of the bottom plate 21 and the back shell 2.

[0093] In some embodiments, the protrusions 27 can be block-shaped structures protruding from the side of the bottom plate 21. The side of the protrusions 27 in contact with the second end plate 33 can be flush with the side of the base 261 facing away from the bottom plate 21, so that the second end plate 33 can be abutted against both the protrusions 27 and the base 261.

[0094] In the embodiment, when the terminal plate 3 is installed, the rear shell 2 can be laid flat, the terminal plate 3 is pushed into the inside of the installation window 24 along the direction, the second buckle 34 on the body 31 is buckled on the first buckle 23 on the bottom plate 21, the terminal plate 3 is pushed to one side, the second end plate 33 of the terminal plate 3 falls into the limiting space formed by the limiting part 26 and the side wall 22, the preliminary fixation of the terminal plate 3 and the rear shell 2 is completed, finally the rear shell 2 is installed on the back plate 1, the third buckle 222 on the rear shell 2 is buckled in the clamping hole on the back plate 1, the rear shell 2 and the back plate 1 are clamped and connected, the first end plate 32 of the terminal plate 3 extends into the clamping groove formed by the side wall 22 of the rear shell 2 and the back plate 1, the limiting fixation of the terminal plate 3 in each direction is completed, and the screwless installation of the terminal plate 3 is realized.
