[0062] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0063] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. In addition, the features defined with "first", "second", "third", "fourth", "fifth" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0064] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "abutment", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0065] In the related art, in electronic products such as servers or terminal products in other fields, there are various fasteners and connection methods between a circuit board and a structural member or between structural members. The more commonly used fastening connection methods mainly include, but are not limited to, bolt connection, rivet connection, snap connection, mortise and tenon connection, and adhesive connection. However, during production assembly and later maintenance, these connection methods require tools for disassembly and assembly, with low disassembly and assembly efficiency. In some connection methods, there is strong stress between the fastener and the product during disassembly and assembly, and the product is easily damaged during the disassembly and assembly process, reducing the yield of the product. In addition, in some connection methods, the fastener needs to be damaged during disassembly, resulting in non-reusability.

[0066] In view of the above problems existing in the prior art, the present application provides a fastener, a connection assembly, and an electronic device. By pushing the clamping component to move along the axial direction of the fastener, the clamping component drives the elastic member to move, causing the elastic member to extend in the axial direction or the radial direction of the fastener. When the elastic member extends in the radial direction, the fastener is in a fastened state, and when the elastic member extends in the axial direction, the fastener is in a detachable state. Therefore, rapid disassembly and assembly can be carried out without tools, and the two components are connected through the deformation of the elastic member. No great stress is generated during the disassembly and fastening processes, reducing damage to the components. In addition, the fastener provided in the present application can also be reused.

[0067] Such as Figures 1-6As shown, a fastener 100 according to an embodiment of the present invention is used to connect a first component 200 and a second component 300. The fastener 100 has a first state and a second state. The fastener 100 includes: a housing 110. When the fastener 100 is in the first state, the housing 110 at least partially abuts against the first component 200 to limit the displacement of the first component 200 in a direction away from the second component 300; a clamping component 120. At least part of the clamping component 120 is located inside the housing 110. The clamping component 120 is movably connected to the housing 110. The clamping component 120 can move along the axial direction of the housing 110 to drive the fastener 100 to switch between the first state and the second state; an elastic member 130, which is connected to the clamping component 120. At least part of the elastic member 130 is located inside the housing 110. When the fastener 100 is in the first state, the elastic member 130 extends in the radial direction of the fastener 100 and abuts against the second component 300 to limit the displacement of the second component 300 in a direction away from the first component 200. When the fastener 100 is in the second state, the elastic member 130 extends in the axial direction of the fastener 100.

[0068] Wherein, at least part of the clamping component 120 and the elastic member 130 are located inside the housing 110, so that the clamping component 120 and the elastic member 130 move in a fixed direction when subjected to a force. At the same time, the housing 110 can also be used to protect and support the fastener 100, improving the stability of the fastener 100 in connecting the first component 200 and the second component 300.

[0069] Specifically, mounting holes 400 are provided on the first component 200 and the second component 300. At least part of the fastener 100 can pass through the mounting holes 400 of the first component 200 and the second component 300. When the fastener 100 is in the first state, at least part of the housing 110 abuts against the first component 200 to limit the displacement of the first component 200 in the direction away from the second component 300, and the fastener 100 cannot escape from the side of the mounting hole 400 close to the elastic member 130. The elastic member 130 extends in the radial direction of the fastener 100 and abuts against the second component 300 to limit the displacement of the second component 300 in the direction away from the first component 200, and the fastener 100 also cannot escape from the side of the mounting hole 400 away from the elastic member 130. Therefore, at least part of the fastener 100 is located in the mounting hole 400, and the elastic member 130 and the housing 110 are respectively blocked on both sides of the two components, connecting the first component 200 and the second component 300. So at this time, the fastener 100 is in a tightened state. When the fastener 100 is in the second state, the elastic member 130 extends in the axial direction of the fastener 100 and can pass through the mounting holes 400 of the first component 200 and the second component 300. The fastener 100 can be disassembled from the first component 200 and the second component 300, and at the same time, the first component 200 and the second component 300 can also be separated. So at this time, the fastener 100 is in a detachable state.

[0070] In practice, the clamping component 120 is movably connected to the housing 110 and can move axially along the fastener 100 relative to the housing 110. Only by pushing the clamping component 120 can the fastener 100 be driven to switch between the first state and the second state. When the clamping component 120 is pushed to displace in the direction close to the elastic member 130, the elastic member 130 deforms when it receives the force of the clamping component 120. The elastic member 130 changes from extending in the axial direction of the fastener 100 to extending in the radial direction of the fastener 100, making the fastener 100 unable to escape from the mounting hole 400, that is, the fastener 100 is in the first state. When the clamping component 120 is pushed to displace in the direction away from the elastic member 130, the clamping component 120 removes the force on the elastic member 130, and the elastic member 130 bounces up and changes from extending in the radial direction of the fastener 100 to extending in the axial direction of the fastener 100. The elastic member 130 can pass through the mounting hole 400, that is, the fastener 100 is in the second state. Therefore, without using tools, only by pushing the clamping component 120, the fastener 100 can be switched between the first state and the second state, that is, the tightened state and the detachable state.

[0071] It can be understood that the clamping component 120 is at least partially located inside the housing 110. When the fastener 100 is in the first state, the clamping component 120 will not come out of the housing 110. The clamping component 120 can be provided with a pressing part or a pushing part outside the housing 110, and the clamping component 120 can be pushed to move through the pressing part or the pushing part. Or a part of the clamping component 120 is arranged outside the housing 110, and the clamping component 120 can be directly pushed to move. Or the housing 110 is provided with a through hole, and the clamping component 120 can be pushed to move from the through hole. When the fastener 100 is in the first state, the clamping component 120 can be positioned to limit the movement of the clamping component 120 and the elastic member 130. When it is necessary to switch to the second state, applying a force to the clamping component 120 again can make it slide out or be pushed out, or the clamping component 120 can be reset by setting a reset button. As long as the clamping component 120 can position and reset the elastic member 130, there are no excessive restrictions in this embodiment.

[0072] Thus, the fastener 100 of the embodiment of the present utility model can be quickly installed and disassembled without tools, only by pushing the clamping component 120, and can be reused. Moreover, the fastener 100 of the embodiment of the present utility model will not generate great stress on the installation component, improving the yield of production and after-sales.

[0073] In some embodiments, the housing 110 includes a first housing 111 and a first housing 112. A limiting surface is formed between the first housing 111 and the second housing 112. The first housing 111 and the first housing 112 form a receiving cavity, and the clamping component 120 and the elastic member 130 are at least partially located in the receiving cavity.

[0074] Specifically, the housing 110 includes a first housing 111 and a first housing 112 to reduce the assembly difficulty of the fastener 100. The cross-sectional diameter of the first housing 111 is larger than the cross-sectional diameter of the mounting hole 400, and the cross-sectional diameter of the second housing 112 is smaller than the diameter of the mounting hole 400. A limiting surface is formed between the first housing 111 and the second housing 112. Therefore, the second housing 112 can pass through the mounting hole 400, and the first housing 111 cannot pass through the mounting hole 400. Thus, the first housing 111 abuts against the first component 200, so that the fastener 100 cannot come out of the mounting hole 400 in the first state. The first housing 111 and the first housing 112 form a receiving cavity, and the clamping component 120 and the elastic member 130 are at least partially located in the receiving cavity. Therefore, the clamping component 120 and the elastic member 130 will not come out of the housing 110, and there is no need to assemble the fastener 100 during use, improving the installation efficiency.

[0075] It can be understood that the first housing 111 and the first housing 112 can be detachably connected or fixedly connected, and there are no excessive restrictions in this embodiment.

[0076] In some embodiments, the first housing 111 is provided with a through hole, and the clamping component 120 is provided with a pressing part 121. At least a part of the pressing part 121 is located outside the through hole, and the pressing part 121 is configured to drive the clamping component 120 to move along the axial direction of the fastener 100 when being pressed.

[0077] Specifically, referring to Figures 2-8 As shown, the clamping component 120 is provided with a pressing part 121 and protrudes from the housing 110. When pressed, the clamping component 120 can be pushed to move towards the elastic member 130, causing the elastic member 130 to deform. At the same time, the fastener 100 switches between the first state and the second state, so the disassembly and assembly of the fastener 100 are more convenient and fast. The pressing part 121 can be at the top of the housing 110 or any position convenient for pressing, and there are no excessive restrictions in this embodiment.

[0078] In some embodiments, referring to Figure 11 As shown, one end of the second housing 112 close to the elastic member 130 is provided with a guiding part 1121 and an avoidance hole 1122. The guiding part 1121 is arranged on the inner surface of the second housing 112 and extends along the radial direction of the second housing 112 to the avoidance hole 1122. The elastic member 130 includes at least one elastic arm, and the elastic arm can move along the guiding part 1121, and the elastic arm can extend out or retract from the avoidance hole 1122.

[0079] One end of the second housing 112 close to the elastic member 130 is provided with a guiding part 1121 and an avoidance hole 1122. When the elastic member 130 is pushed, the elastic member 130 can move along the guiding part 1121, and the elastic arm on the elastic member 130 extends out from the avoidance hole 1122 and abuts against the second component 300. The guiding part 1121 and the avoidance hole 1122 enable the elastic member 130 to more quickly extend and deform from the axial direction of the fastener 100 to the radial direction of the fastener 100 when being acted on by a force.

[0080] In some embodiments, a guiding component is provided between the inner surface of the housing 110 and the clamping component 120. The guiding component extends in the axial direction of the fastener 100, and the clamping component 120 can move along the guiding component.

[0081] It can be understood that a guiding component is provided between the inner surface of the housing 110 and the clamping component 120. The guiding component extends in the axial direction of the fastener 100. When the clamping component 120 displaces along the guiding component, offset can be prevented to ensure that when the clamping component 120 is pushed, the clamping component 120 displaces in the axial direction of the fastener 100.

[0082] Specifically, the guiding component can be a protrusion and a guiding groove. One of the inner surface of the housing 110 and the clamping component 120 is provided with a protrusion, and the other is provided with a guiding groove. The protrusion is located in the guiding groove and can move relative to the guiding groove. The protrusion and the guiding groove can be one or more. When there are multiple ones, they are arranged along the circumferences of the inner surface of the housing 110 and the clamping component 120. The specific structure of the guiding component is not limited in this embodiment.

[0083] In some embodiments, the guiding component includes at least one protrusion 1111 and at least one guiding groove 122. The protrusion 1111 is arranged on the inner surface of the housing 110, and the guiding groove 122 is arranged on the outer peripheral side of the clamping component 120. A stop groove 123 is provided on the clamping component 120. When the protrusion 1111 is located in the guiding groove 122, the fastener 100 is in the second state. When the protrusion 1111 is located in the stop groove 123, the fastener 100 is in the first state.

[0084] Specifically, when the protrusion 1111 is located in the guiding groove 122, the protrusion 1111 can move along the guiding groove 122. Therefore, the clamping component 120 can move axially relative to the housing 110. At this time, the elastic member 130 can extend in the axial direction of the fastener 100, and the fastener 100 is in the first state. When the protrusion 1111 is located in the stop groove 123, the protrusion 1111 abuts against the clamping component 120, preventing the clamping component 120 from moving away from the elastic member 130. At this time, the elastic member 130 is extended in the radial direction of the fastener 100 under the action of the clamping component 120, and the fastener 100 is in the second state.

[0085] It can be understood that the protrusion 1111 can move relative to the clamping component 120 into the guiding groove 122 or the stop groove 123. By pushing the clamping component 120 into the guiding groove 122 or the stop groove 123, the switching between the first state and the second state of the fastener 100 can be realized. The specific movement method is not limited in this embodiment.

[0086] In some embodiments, the clamping component 120 includes a first clamping mechanism 124 and a second clamping mechanism 125. The first clamping mechanism 124 and the second clamping mechanism 125 are rotatably connected. The guiding groove 122 includes a first guiding groove 1221 and a second guiding groove 1222. The first guiding groove 1221 is located on the first clamping mechanism 124, the second guiding groove 1221 is located on the second clamping mechanism 125, and the stop groove 123 is located on the second clamping mechanism 125.

[0087] Specifically, the clamping component 120 includes a first clamping mechanism 124 and a second clamping mechanism 125. The first clamping mechanism 124 and the second clamping mechanism 125 can rotate relative to each other. When rotated to a position where the first guiding groove 1221 corresponds to the second guiding groove 1222, when the clamping component 120 is pushed, the protruding portion 1111 can slide along the first guiding groove 1221 and enter the second guiding groove 1222. When rotated to a position where the first guiding groove 1221 corresponds to the stop groove 123, when the clamping component 120 is pushed, the protruding portion 1111 abuts against the stop groove 123. Thus, by relatively rotating the first clamping mechanism 124 and the second clamping mechanism 125, it is possible to switch between the first state and the second state of the fastener 100.

[0088] In some embodiments, referring to Figures 5-10 As shown, at one end of the protruding portion 1111 close to the elastic member 130, there is provided a first inclined surface 1112. The second clamping mechanism 125 includes a second inclined surface 1251 and a third inclined surface 1252 that cooperate with the first inclined surface 1112. The second inclined surface 1251 and the third inclined surface 1252 are sequentially arranged between the guiding groove 122 and the stop groove 123.

[0089] Specifically, the guiding groove 122 and the stop groove 123 are provided on the clamping component 120. The second inclined surface 1251 and the third inclined surface 1252 are sequentially arranged between the guiding groove 122 and the stop groove 123. The first inclined surface 1112 can slide relative to the second inclined surface 1251 and the third inclined surface 1252. Therefore, when the protruding portion 1111 is located in the stop groove 123, the protruding portion 1111 can slide along the second inclined surface 1251 and can slide from the stop groove 123 into the guiding groove 122. When the protruding portion 1111 is located in the guiding groove 122, the protruding portion 1111 can slide along the third inclined surface 1252 and can slide from the guiding groove 122 back into the stop groove 123. The second inclined surface 1251 and the third inclined surface 1252 are sequentially arranged between the guiding groove 122 and the stop groove 123. Therefore, the protruding portion 1111 can move between the guiding groove 122 and the stop groove 123 in sequence. Thus, by pushing and rotating the clamping component 120 and the housing 110, the fastener 100 can be switched between the first state and the second state.

[0090] In some embodiments, the first clamping mechanism 124 further includes a plurality of fourth inclined surfaces 1241 and fifth inclined surfaces 1242, and the fourth inclined surfaces 1241 and the fifth inclined surfaces 1242 cooperate with the second inclined surface 1251 and the third inclined surface 1252.

[0091] Specifically, when the first clamping mechanism 124 rotates relative to the second clamping mechanism 125, the fourth inclined surface 1241 and the fifth inclined surface 1242 can slide relative to the second inclined surface 1251 and the third inclined surface 1252. The fourth inclined surface 1241 and the fifth inclined surface 1242 have a guiding effect. When the protruding portion 1111 moves relative to the second inclined surface 1251 or the third inclined surface 1252, it drives the second clamping mechanism 125 to rotate relative to the first clamping mechanism 124.

[0092] Exemplarily, referring to Figures 5-8 As shown, when the fastener 100 is in the first state, the clamping assembly 120 reserves a movement space in the direction of the elastic member 130, and the elastic member 130 reserves a compression space in the direction away from the clamping assembly 120 when being pushed by the clamping component 120. Therefore, when the fastener 100 is in the first state, it can push the clamping assembly 120 to move in the direction of the elastic member 130, so that the elastic member 130 has greater elastic potential energy. At this time, when the clamping assembly 120 is released, the elastic member 130 recovers its deformation and pushes the clamping assembly 120 to move in the direction away from the elastic member 130. At this time, the second inclined surface 1251 slides relative to the fifth inclined surface 1242, and the third inclined surface 1252 slides relative to the fourth inclined surface 1241. At the same time, the protruding portion 1111 slides into the guiding groove 122 relative to the second inclined surface 1251, and the fastener 100 switches to the second state. At this time, the protruding portion 1111 is located in the guiding groove 122, the second inclined surface 1251 corresponds to the fourth inclined surface 1241, and the third inclined surface 1252 corresponds to the fifth inclined surface 1242. When the first clamping mechanism 124 is pushed, the second inclined surface 1251 slides relative to the fourth inclined surface 1241, and the third inclined surface 1252 slides relative to the fifth inclined surface 1242. At the same time, the protruding portion 1111 slides into the stop groove 123 relative to the third inclined surface 1252, and the elastic member 130 abuts against the second clamping mechanism 125, and the fastener 100 switches to the first state. Therefore, only by pushing the first clamping mechanism 124, the second clamping mechanism 125 automatically rotates under the guiding action of the first clamping mechanism 124, and the protruding portion 1111 sequentially falls into the guiding groove 122 and the stop groove 123, and the fastener 100 sequentially switches between the first state and the second state.

[0093] In some embodiments, the clamping assembly 120 is provided with a plurality of guiding grooves 122 and a plurality of stop grooves 123. The plurality of guiding grooves 122 and the plurality of stop grooves 123 are sequentially and spaced apart on the outer peripheral side of the clamping assembly 120. The second clamping mechanism 125 includes a plurality of second inclined surfaces 1251 and a plurality of third inclined surfaces 1252, and the first clamping mechanism 124 includes a plurality of fourth inclined surfaces 1241 and a plurality of fifth inclined surfaces 1242.

[0094] Specifically, the clamping component 120 is provided with a plurality of guiding grooves 122 and a plurality of stopping grooves 123. When the protruding part 1111 is located in any one of the guiding grooves 122, the fastener 100 is in the second state. When the protruding part 1111 is located in any one of the stopping grooves 123, the fastener 100 is in the first state. The plurality of guiding grooves 122 and the plurality of stopping grooves 123 are arranged at intervals, facilitating the movement of the protruding part 1111 in the guiding grooves 122 and the stopping grooves 123. When the clamping component 120 is pushed, the plurality of second inclined surfaces 1251 slide relative to the plurality of fifth inclined surfaces 1242, and the plurality of third inclined surfaces 1252 slide relative to the plurality of fourth inclined surfaces 1241. At the same time, the protruding part 1111 slides out along the third inclined surface 1252 and enters the guiding groove 122. When the clamping component 120 is pushed again, the plurality of second inclined surfaces 1251 slide relative to the plurality of fourth inclined surfaces 1241, and the plurality of third inclined surfaces 1252 slide relative to the plurality of fifth inclined surfaces 1242. At the same time, the protruding part 1111 slides out along the fourth inclined surface 1241 and enters the stopping groove 123. Therefore, the protruding part 1111 can successively and continuously fall into the guiding groove 122 and the stopping groove 123, enabling the fastener 100 to switch between the first state and the second state successively when the clamping component 120 rotates.

[0095] It can be understood that the protruding part 1111 can be one or multiple. When there are multiple protruding parts 1111, the multiple protruding parts 1111 can correspond to the multiple guiding grooves 122 simultaneously, or the multiple protruding parts 1111 can correspond to the multiple stopping grooves 123 simultaneously. There are no excessive restrictions in this embodiment.

[0096] In some embodiments, the fastener 100 further includes a limiting ring 140, and the limiting ring 140 is disposed between the housing 110 and the first component 200.

[0097] Specifically, the limiting surface on the housing 110 and the first component 200 are also provided with the limiting ring 140, and the limiting ring 140 can be adjusted according to the first component 200 and the second component 300, enabling the fastener 100 to be applicable to first components 200 and second components 300 with different thicknesses.
