That is to say, the exterior panel 1 and the shell 2 in the utility model are positioned and locked by three different structures, and are positioned and locked in the plug-in direction as well as in a direction different from the plug-in direction, so as to ensure the stability of the assembly structure and enable the exterior panel 1 and the shell 2 to be stably assembled together. In addition, the utility model does not require the use of screws / screws for assembly, and is directly assembled by plug-in locking, so it is fast to assemble and has extremely high assembly efficiency.

[0028] The elastic embedded clip 22 includes a first elastic piece 221 and a second elastic piece 222 integrally formed on the housing 2 and spaced apart, the first elastic piece 221 and the second elastic piece 222 are both extended and distributed along the insertion direction, and the ends of the first elastic piece 221 and the second elastic piece 222 are respectively formed with a first arc-shaped buckle body 201 and a second arc-shaped buckle body 202 which are symmetrically distributed and used to hold and position the elastic sheath clip 12.

[0029] The elastic sheath clip 12 includes a first elastic clip 121 and a second elastic clip 122 which are integrally formed on the exterior panel 1 and are spaced apart. The first elastic clip 121 and the second elastic clip 122 are both extended and distributed along the insertion direction, and the ends of the first elastic clip 121 and the second elastic clip 122 are respectively formed with a first arc-shaped clip 101 and a second arc-shaped clip 102 which are symmetrically distributed and respectively adapted to the first arc-shaped buckle body 201 and the second arc-shaped buckle body 202, and the ends of the first arc-shaped clip 101 and the second arc-shaped clip 102 are respectively formed with a first arc-shaped clip 101 and a second arc-shaped clip 102. The spacing dimension between the ends of the first arc-shaped buckle body 201 and the second arc-shaped buckle body 202 is greater than the spacing dimension between the ends of the first arc-shaped buckle body 201 and the second arc-shaped buckle body 202.

[0034] The protruding buckle 11 protrudes forward from the rear end, and the angle between the protruding buckle 11 and the plugging direction is greater than 60 degrees, so that the exterior panel 1 and the housing 2 are stably assembled together.

[0035] The housing 2 is further provided with a positioning piece 27 , and the exterior panel 1 is provided with a positioning groove 15 , and the positioning piece 27 is embedded in the positioning groove 15 , so that the assembly of the exterior panel 1 and the housing 2 is more stable and the assembly structure is more solid.

[0036] In summary, after the exterior panel 1 and the shell 2 are plugged and assembled, the buckle 21 is engaged with the convex buckle 11 for positioning and locking in a direction different from the plugging direction, the elastic sleeve clip 12 is clamped and fixed to the outside of the elastic embedded clip 22 for positioning and locking in the plugging direction, and the undercut 23 is snapped into the card slot 13 for positioning and locking in the plugging direction. In other words, the exterior panel 1 and the shell 2 in the utility model are positioned and locked through three different structures, and are positioned and locked in the plugging direction and in a direction different from the plugging direction, so as to ensure the stability of the assembly structure, so that the exterior panel 1 and the shell 2 are stably assembled together. In addition, the utility model does not need to be assembled by screws / screws, and is directly assembled by plugging and locking, so it is fast to assemble and has extremely high assembly efficiency.
