[0033] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0034] As used herein, the term "comprising" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise specified, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc. may refer to different or the same objects.

[0035] As described above, in some narrow spaces or application scenarios with a relatively deep installation depth, it is easy for fasteners to fall off during installation or disassembly due to inconvenient installation. Especially when installing or disassembling fasteners in electrical equipment, the falling off of fasteners may even cause safety hazards. Embodiments of the present disclosure provide a fastening assembly and an installation structure to at least partially solve the above problems. Hereinafter, the principle of the present disclosure will be described in conjunction with Figures 1 to 8 the present disclosure.

[0036] Figure 1 The structural schematic diagram of an installation structure according to some embodiments of the present disclosure is shown. Figure 2 The installation schematic diagram of the fastening assembly 100 according to some embodiments of the present disclosure is shown. Figure 3 The structural schematic diagram of the fastening assembly 100 according to some embodiments of the present disclosure is shown. As Figures 1 to 3 shown, the fastening assembly 100 described herein is disposed on the target object 200, and the fastening assembly 100 generally includes a fastener 1, a limiting member 2, and an anti-detachment member 3.

[0037] Referring to Figures 1 to 2 , in some embodiments, the target object 200 may be a distribution box, which includes a front cover 201 and a rear cover 202 connected to the front cover 201. A plurality of plug-ins 300 may be disposed on the front cover 201. The inventors have noticed that, on the one hand, since the front cover 201 has an open structure, it is impossible to provide a support structure for setting fasteners inside the target object 200. On the other hand, due to the high installation density of the plurality of plug-ins 300 and considering the space requirements for installing male and female plugs, the depth space of the target object 200 cannot be occupied along the drawer insertion direction, which also results in the inability to provide an internal support structure.

[0038] Figure 4 Shows Figure 3 the exploded view of the fastening assembly 100 shown in Figures 3 to 4As shown, in some embodiments, the limiting member 2 includes a connecting portion 21 and an elastic portion 22. The connecting portion 21 is connected to the elastic portion 22 and together with the elastic portion 22 encloses an accommodation space 101. The fastener 1 can be located within the accommodation space 101. The fastener 1 contacts the inner surface of the elastic portion 22 and is blocked by the elastic portion 22 to prevent the fastener 1 from coming out of the accommodation space 101. The anti - detachment member 3 is connected to the connecting portion 21 and covers the connecting portion 21 to prevent the fastener 1 from coming out of the accommodation space 101. During the process of screwing the fastener 1 to install the target object 200 and the object to be connected, the fastener 1 can drive the elastic portion 22 to expand, so as to prevent the elastic portion 22 from blocking the fastener 1 during the installation process.

[0039] According to the embodiment of the present disclosure, the fastener 1 is located in the accommodation space 101, and one end of the fastener 1 is blocked by the elastic portion 22, and the other end of the fastener 1 is blocked by the anti - detachment member 3. Therefore, when the fastening assembly 100 is pre - installed on the target object 200, even when installing / dismantling the fastening assembly 100 in some narrow spaces or application scenarios with a relatively deep installation depth, the fastener 1 cannot come out, thus avoiding potential safety hazards.

[0040] In addition, since the fastener 1 can drive the elastic portion 22 to expand during the process of screwing the fastener 1 to install the target object 200 and the object to be connected; therefore, during the process of unscrewing the fastener 1 from the object to be connected and the target object 200, the elastic portion 22 will gradually hold the fastener 1 tightly as the fastener 1 retreats, thereby preventing the fastener 1 from coming out. In addition, the fastening assembly 100 can be pre - installed on the rear cover 202, and the fastening assembly 100 does not occupy the depth space of the target object 200, thus avoiding interference between the fastening assembly 100 and the cooperation of the male plug and the female plug, which is beneficial to the installation requirements of the target object 200 with a high - density plug 300.

[0041] The limiting member 2 and the anti - detachment member 3 according to the embodiment of the present disclosure can include various types of materials known currently or available in the future, and the embodiments of the present disclosure do not limit this. For example, in some embodiments, the limiting member 2 and the anti - detachment member 3 can include plastic parts. In addition, the object to be connected can include a base, a cross - beam, a column, etc., which are not limited here.

[0042] Continue to refer to Figures 3 to 4 , in some embodiments, the fastener 1 includes but is not limited to a screw. The fastener 1 can include a head 11 and a rod body 12 connected to the head. An operation hole 32 can be provided on the anti - detachment member 3, and the size of the operation hole 32 can be smaller than the size of the head 11. Thus, the anti - detachment member 3 can block the fastener 1 to prevent the fastener 1 from coming out of the accommodation space 101. In addition, the operation hole 32 facilitates the operator to screw in or out the fastener 1.

[0043] Figure 5A cross-sectional view of the limiting member 2 according to some embodiments of the present disclosure is shown. As Figures 4 to 5 shown, in some embodiments, the elastic portion 22 may include a plurality of clamping portions 221. The plurality of clamping portions 221 are respectively arranged on the connecting portion 21. The fastener 1 may contact the inner surfaces of the plurality of clamping portions 221 and be blocked by the plurality of clamping portions 221 to prevent the fastener 1 from coming out of the accommodation space 101. Adjacent clamping portions 221 among the plurality of clamping portions 221 may be spaced apart from each other, and a gap 222 is provided between adjacent clamping portions 221 among the plurality of clamping portions 221. It can be understood that the existence of the gap 222 helps the elastic portion 22 to expand.

[0044] Figure 6 A cross-sectional view of the fastening assembly 100 in an installed state according to some embodiments of the present disclosure is shown. As Figures 4 to 6 shown, further, along the direction X in which the fastener 1 is screwed in, the distance between each clamping portion 221 among the plurality of clamping portions 221 and the central axis of the rod body 12 gradually decreases. Thus, during the process of screwing in the fastener 1, the fastener 1 can drive the plurality of clamping portions 221 to expand outwards. In addition, during the process of unscrewing the fastener 1, the plurality of clamping portions 221 will gradually hold the fastener 1 tightly as the fastener 1 retreats.

[0045] The clamping portion 221 according to the embodiments of the present disclosure may include an inner surface of any shape, and the embodiments of the present disclosure do not limit this. For example, as Figure 5 shown, in some embodiments, the inner surface of the clamping portion 221 may be an arc surface. In other embodiments, the inner surface of the clamping portion 221 may also be a flat surface.

[0046] Referring to Figures 4 to 6 , further, the plurality of clamping portions 221 may include paired clamping portions 221, and each pair of clamping portions 221 among the paired clamping portions 221 may be arranged opposite to each other. For example, the plurality of clamping portions 221 may include two pairs of clamping portions 221; correspondingly, the number of gaps 222 is four.

[0047] It should be noted that the numbers, numerical values, quantities, etc. mentioned above and elsewhere in the present disclosure are all exemplary and are not intended to limit the scope of the present disclosure in any way. Any other appropriate numbers, numerical values, quantities are possible. For example, referring to Figures 4 to 6 , according to specific application scenarios and requirements, the plurality of clamping portions 221 may include a greater or smaller number.

[0048] Returning to reference Figures 4 to 5, in some embodiments, a plurality of mounting grooves 211 may be provided on the connecting portion 21, and the plurality of mounting grooves 211 communicate with corresponding gaps 222 respectively. The anti - detachment member 3 may further include at least two mounting portions 31. A part of each of the at least two mounting portions 31 is located in the corresponding mounting groove 211, and another part of each mounting portion 31 is located in the corresponding gap 222 and is limited by the connecting portion 21. Thus, the clamping connection between the anti - detachment member 3 and the limiting member 2 is achieved.

[0049] Continue to refer to Figures 4 to 6 , in some embodiments, the head 11 may contact the inner surface of the elastic portion 22 and be blocked by the elastic portion 22, and the contact position between the head 11 and the elastic portion 22 is adjacent to the connecting portion 21. Thus, during the process of screwing the fastener 1 in, the fastener 1 can drive the plurality of clamping portions 221 to expand outwards through the head 11.

[0050] Continue to refer to Figure 3 、 Figure 4 and Figure 6 , in some embodiments, at least two clamping members 4 may be provided on the anti - detachment member 3, and the at least two clamping members 4 are adapted to be clamped to the target object 200. Thus, the clamping connection between the fastening assembly 100 and the target object 200 is achieved. Of course, the fastening assembly 100 can also be connected to the target object 200 in any connection manner, for example, including but not limited to bonding or integral connection, etc., and the embodiments of the present disclosure do not limit this.

[0051] Figure 7 FIG. shows a schematic structural view of a fastening assembly 100 according to other embodiments of the present disclosure. Figure 8 FIG. shows Figure 7 an exploded view of the fastening assembly 100 shown in Figures 7 to 8 The fastening assembly 100 shown in Figures 3 to 4 has a similar structure to the fastening assembly 100 shown in

[0052] As Figures 7 to 8 shown, in some embodiments, at least two clamping members 4 may be provided on the limiting member 2, and the at least two clamping members 4 are adapted to be clamped to the target object 200. Thus, the clamping connection between the fastening assembly 100 and the target object 200 is achieved.

[0053] Return to refer to Figure 1 , the embodiments of the present disclosure further provide an installation structure, which includes any one of the above - mentioned fastening assemblies 100. The fastening assembly 100 can be arranged on the target object 200.

[0054] Return to refer to Figure 2and Figure 6 , in some embodiments, the target object 200 may further include a plurality of through holes 203 and a plurality of sets of clamping structures. The plurality of through holes 203 and the plurality of sets of clamping structures are respectively arranged on the rear cover 202. Each of the plurality of through holes 203 is aligned with the rod body 12 of the fastener 1, so that the target object 200 is connected to the object to be connected through the fastener 1.

[0055] Continuing to refer to Figure 2 and Figure 6 , further, each of the plurality of sets of clamping structures may include at least two clamping bosses 204, and at least two clamping members 4 are arranged in the at least two clamping bosses 204, so that the fastening assembly 100 is clamped to the rear cover 202. Of course, the fastening assembly 100 can also be connected to the target object 200 in any connection manner. For example, including but not limited to bonding or integral connection, etc. The embodiments of the present disclosure do not limit this.
