[0045] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0046] See also Figures 1-6 The embodiment of the present application provides a shell 1, which includes a shell and a stopper 40, the shell includes a first shell 10 and a second shell 20; the first shell 10 and the second shell 20 are arranged opposite to each other and enclose a mounting cavity; the first shell 10 is provided with a snap 30, and the second shell 20 is provided with a snap hole 211, the snap 30 can be moved to be engaged with or disengaged from the snap hole 211 to lock or unlock the first shell 10 and the second shell 20; the stopper 40 is provided on the shell and is provided corresponding to the snap 30; wherein, when the snap 30 is disengaged from the snap hole 211, it can move to abut against the stopper 40.

[0047] In this way, the first shell 10 and the second shell 20 are locked together by the buckle 30 being locked in the locking hole 211. Secondly, in order to prevent the buckle 30 from being permanently deformed or broken under the action of external force, the present application provides a stopper 40 on the second shell 20 to limit the movement of the buckle 30 away from the locking hole 211. This allows the second end of the buckle 30 to be disengaged from the locking hole 211 under the action of external force, while also limiting the movement of the buckle 30 through the provision of the stopper 40. The provision of the stopper 40 prevents the buckle 30 from being permanently deformed or broken during its movement from the locking hole 211 under the action of external force, thereby increasing the service life of the buckle 30 and facilitating the service life of the housing.

[0048] In the examples of this application, see Figure 2The first shell 10 defines a first accommodating cavity 11, and the second shell 20 defines a second accommodating cavity 21. The first accommodating cavity 11 and the second accommodating cavity 21 are connected to form an installation cavity. One end of the buckle 30 is connected to the cavity wall of the first accommodating cavity 11, and the other end can be moved to engage or disengage from the engaging hole 211; the stopper 40 is connected to the cavity wall of the second accommodating cavity 21 and extends toward the direction of the first accommodating cavity 11, thereby defining a first gap 22 between the stopper 40 and the side wall of the second accommodating cavity 21. The buckle 30 can be deformed under the action of an external force so that the second end of the buckle 30 moves from the first position back to the engaging hole 211 to the first gap 22. The buckle 30 can move within the first gap 22 under the action of an external force.

[0049] For example, one end of the buckle 30 connected to the side wall of the first accommodating cavity 11 is defined as the first end of the buckle 30, and the other end is defined as the second end of the buckle 30. Similarly, one end of the stopper 40 connected to the cavity wall of the second accommodating cavity 21 is defined as the first end of the stopper 40, and the other end is defined as the second end of the stopper 40.

[0050] The first end of the buckle 30 is connected to the side wall of the first accommodating cavity 11 . The side wall of the second accommodating cavity 21 is provided with a snap-fitting hole 211 . The stopper 40 is disposed in the second accommodating cavity 21 .

[0051] The first accommodating cavity 11 and the second accommodating cavity 21 respectively have an opening, and the opening of the first accommodating cavity 11 and the opening of the second accommodating cavity 21 are arranged to face each other.

[0052] The second end of the buckle 30 can move between a first position and a second position. Figure 5 When the second end of the buckle 30 is located at the first position, the second end of the buckle 30 is locked in the locking hole 211. Figure 6 When the second end of the buckle 30 moves from the first position back toward the locking hole 211 to the second position under the action of external force, the second end of the buckle 30 disengages from the locking hole 211, and the stopper 40 abuts against the second end of the buckle 30 to limit the movement of the buckle 30 back toward the locking hole 211.

[0053] In the examples of this application, see Figure 5 When the second end of the buckle 30 is in the first position, the first shell 1 and the second shell 1 are in a locked state, and the first shell 10 and the second shell 20 cannot be separated. Figure 6 When the second end of the buckle 30 is in the second position, the first and second housings 1 and 20 are unlocked, allowing the first and second housings 10 and 20 to separate. At this point, the buckle 30 is deformed. More specifically, when no external force is applied to the buckle 30, the second end of the buckle 30 is retained within the engaging hole 211. When an external force is applied to the buckle 30, the second end of the buckle 30 is released from the engaging hole 211.

[0054] In some embodiments, the buckle 30 is integrally formed with the first housing 10. The buckle 30 deforms when subjected to an external force and resets when the external force disappears, disengaging from or snapping into the engaging hole 211. The stopper 40 is integrally formed with the second housing 20, thereby saving production time and cost and improving product quality and performance.

[0055] In some embodiments, the first housing 10, the buckle 30, the second housing 20, and the stopper 40 are all made of plastic material, and the properties of the plastic material itself can be used to achieve deformation and resetting of the buckle.

[0056] In some embodiments, see Figure 2 The buckle 30 includes a first elastic portion 31 and a first hook portion 32, one end of the first elastic portion 31 is connected to the side wall of the first accommodating cavity 11; the first hook portion 32 is arranged at the second end of the first elastic portion 31, and is located on the side of the first elastic portion 31 facing away from the stop member 40; wherein, the first hook portion 32 can be moved to engage in or disengage from the engaging hole 211.

[0057] When the second end of the buckle 30 is in the first position, the first hook portion 32 is engaged with the engaging hole 211. When the second end of the buckle 30 moves from the first position away from the engaging hole 211 to the second position under the action of an external force, the first hook portion 32 disengages from the engaging hole 211, and the stopper 40 abuts against the first elastic portion 31 to restrict the second end of the first elastic portion 31 from moving away from the engaging hole 211.

[0058] In some embodiments, the first hook portion 32 is provided with an inclined surface 321. When the first hook portion 32 is inserted into the engaging hole 211, the second housing 20 slides along the inclined surface 321. The provision of the inclined surface enables the first elastic portion 31 to deform when a force is applied to the first hook portion 32, thereby enabling the first hook portion 32 to be inserted into the engaging hole 211.

[0059] According to the embodiment of the present application, the first hook portion 32 can be locked in the engaging hole 211 to prevent the first shell 10 and the second shell 20 from separating. Secondly, the stopper 40 abuts against the second end of the first elastic portion 31 to limit the further deformation of the first elastic portion 31 after it is separated from the engaging hole 211, thereby protecting the first elastic portion 31 and preventing it from being permanently deformed or broken by external forces.

[0060] In some embodiments, see Figure 5The engaging hole 211 and the stopper 40 are spaced apart along the first direction, and the dimension L of the first gap 22 in the first direction is greater than the sum of the dimensions of the first elastic portion 31 and the first hook 32 in the first direction. Such an arrangement enables the first elastic portion 31 and the first hook 32 to have enough space to enter the first gap 22 when the first shell 10 and the second shell 20 are clamped toward each other, and the first hook 32 is clamped into the engaging hole 211 by the reset force of the first elastic portion 31.

[0061] It should be noted that the specific size of the first gap 22 needs to be determined according to the material used for the first elastic part 31, and the maximum size of the first gap 22 needs to be calculated based on the stress test of the first elastic part 31. Then, during the design, the size of the first gap 22 can be set to be smaller than the maximum size of the first gap 22. No limitation is made here.

[0062] In some embodiments, there are plural buckles 30 , stoppers 40 , and engaging holes 211 , and the buckles 30 , stoppers 40 , and engaging holes 211 are disposed in a one-to-one correspondence.

[0063] In some embodiments, a reinforcing rib 43 is provided on the stop member 40 , and the reinforcing rib 43 connects the stop member 40 and the cavity wall of the second accommodating cavity 21 . The reinforcing rib 43 can prevent the stop member 40 from breaking, which is beneficial to enhancing the strength of the stop member 40 .

[0064] In some embodiments, a first protrusion 50 is provided on the side of the second housing 20 facing the first housing 10, and a first positioning portion 60 is provided on the side of the first housing 10 facing the second housing 20, which is compatible with the first protrusion 50. The first protrusion 50 is embedded in the first positioning portion 60, thereby achieving positioning between the first housing 10 and the second housing 20. For example, there are four first protrusions 50 and four first positioning portions 60. The first housing 10 is positioned by snapping into the first positioning portions 60 of the second housing 20 at the four corners of the first protrusion 50, thereby achieving positioning between the first housing 10 and the second housing 20.

[0065] In some embodiments, the first housing 10 and the second housing 20 are provided with heat dissipation holes 1a communicating with the mounting cavity, for dissipating heat 1a from electrical components disposed in the mounting cavity. In other embodiments, the first housing 10 is provided with heat dissipation holes 1a, or the second housing 20 is provided with heat dissipation holes 1a.

[0066] In some embodiments, the stopper 40 includes a connecting portion 41 and a stopping portion 42. The connecting portion 41 is disposed on the wall of the second accommodating cavity 21, and the stopping portion 42 is connected to a side of the connecting portion 41 near the wall of the second accommodating cavity 21. The connecting portion 41 extends toward the engaging hole 211 to form a recessed space 40a with the stopping portion 42. When the buckle 30 is released from the engaging hole 211, it can be moved into the recessed space 40a and abut against the stopping portion 42, thereby limiting the position of the buckle 30. The cross-sectional dimensions of the connecting portion 41 are larger than those of the stopping portion 42, which increases the rigidity of the stopper 40, making it less susceptible to deformation and ensuring positional stability. Specifically, when the buckle 30 contacts the stopper 40, the stopper 40 does not deform, ensuring a stable stopper position.

[0067] See also Figure 7 In some embodiments, a limiting strip 70 is provided on the edge of the first shell 10, and a limiting groove 23 is provided on the edge of the second shell 20. The limiting strip 70 is inserted into the limiting groove 23 to achieve positioning between the first shell 10 and the second shell 20.
