[0089] Before describing the embodiments of the present disclosure in detail, it should be understood that the present disclosure is not limited in its application to the construction and arrangement details of the components set forth in the following description or shown in the accompanying drawings. The present disclosure can have other embodiments and can be practiced or implemented in a variety of different ways. Moreover, it should be understood that the words and terms used in this article are for descriptive purposes and should not be considered restrictive. The use of "including" and "comprising" and their variations is intended to cover the items listed thereafter and their equivalents and additional items and their equivalents. DETAILED DESCRIPTION

[0090] Various specific embodiments of the present application will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "front", "back", "up", "down", "left", "right", "top", "bottom", "inside", "outside", etc., are used in this application to describe various example structural parts and elements of the present application, these terms are used here only for the purpose of convenience of explanation and are determined based on the example orientations shown in the accompanying drawings. Since the embodiments disclosed in this application can be set in different directions, these directional terms are only for illustration and should not be regarded as limitations. Where possible, the same or similar figure numbers used in this application refer to the same parts.

[0091] Figure 1A-1D FIG. 1 shows the basic structure of a fastening clip 100 according to an embodiment of the present application. Figure 1A A three-dimensional structural diagram of the fastening clip 100 is shown in a top view. Figure 1B A three-dimensional structural diagram of the fastening clip 100 at another bottom-up angle is shown. Figure 1C shows a top view of the fastening clip 100, Figure 1D FIG. 1 shows a front view of the fastening clip 100. Figure 1A-1D As shown, the fastening clamp 100 includes a first connecting member 102 and a second connecting member 104, which are detachably connected together. The first connecting member 102 is used to connect to the first component 551 to be fastened, and the second connecting member 104 is used to connect to the second component 552 to be fastened (see Figure 5A and Figure 6AAs shown). Therefore, by disassembling and assembling the first connector 102 and the second connector 104, the first component 551 and the second component 552 can be detachably connected together. In this embodiment, the second connector 104 and the first connector 102 are coaxial, and the second connector 104 is inserted into the first connector 102 along the axial direction and detachably connected to the first connector 102. In this embodiment, the first connector 102 and the second connector 104 are detachably connected together. It will be understood by those skilled in the art that the first connector 102 and the second connector 104 may also be connected together in any other detachable manner.

[0092] In this embodiment, the first connecting member 102 is substantially cylindrical with an axis i. The first connecting member 102 includes a neck 105 and a central channel 108. The neck 105 is annular, and the central channel 108 runs through the center of the neck 105 and extends along the axis i.

[0093] The first connecting member 102 also includes at least one snap-on spring 109, one end of each snap-on spring 109 is connected to the wall defining the central channel 108 to form a connecting end, that is, connected to the inner surface of the neck 105, and the snap-on spring 109 extends obliquely into the central channel 108. The other end of the snap-on spring 109 forms a free end. Thus, the snap-on spring 109 can have a certain elasticity, and the distance between the free end of the snap-on spring 109 and the axis i is smaller than the distance between the connecting end and the axis i. The first connecting member 102 also includes at least one guide bar 107, which is also arranged on the wall defining the central channel 108, that is, arranged on the inner surface of the neck 105, and extends vertically along the axis i. In this embodiment, the first connecting member 102 includes four snap-fit ​​springs 109 and four guide bars 107. The four snap-fit ​​springs 109 are spaced apart in the circumferential direction around the axis i, and the four guide bars 107 are provided between every two adjacent snap-fit ​​springs 109. The snap-fit ​​springs 109 are used to snap-fit ​​with the second connecting member 104, and the central channel 108 is used to receive at least a portion of the second connecting member 104. The more specific structure of the snap-fit ​​springs 109 and the guide bars 107 will be described in detail in conjunction with FIG. Figures 3A to 3D Detailed description.

[0094] The first connector 102 further includes a top flange 101, a bottom flange 103, and a groove 106. The top flange 101 is formed to extend outward from the top of the neck 105, for example, extending horizontally in the radial direction. The bottom flange 103 is formed to extend outward from the bottom of the neck 105, for example, extending horizontally in the radial direction. Thus, the first connector 102 can form a groove 106 between the top flange 101 and the bottom flange 103. The groove 106 is used to receive a plate to be fastened, such as the flat plate portion 555 of the first component 551 (see FIG. 1 ). Figure 5A and 5B (As shown). In this embodiment, the groove 106 is an annular groove. Those skilled in the art will appreciate that the groove 106 of the first connector 102 may also be configured as a groove of any other shape, such as a square ring or a polygonal ring, to receive a first component of another shape that requires fastening. Furthermore, in this embodiment, the top flange 101 and the bottom flange 103 are annular flanges. In other embodiments, the top flange 101 or the bottom flange 103 may also be configured as flanges with outer peripheral walls having a square or other polygonal shape.

[0095] The second connector 104 includes a main body 111, a sleeve 112, and a bell-mouth portion 123, all having a common axis i. The sleeve 112 is connected to the top of the main body 111, and the bell-mouth portion 123 is connected to the bottom of the main body 111. The sleeve 112 is cylindrical and is inserted into the central passage 108 of the first connector 102 and engages with the snap-on spring 109 in the central passage 108. The top of the sleeve 112 has an outwardly protruding step 122. The distance between the step 122 and the axis i is set to be smaller than the distance between the connecting end of the snap-on spring 109 and the axis i, but greater than the distance between the free end of the snap-on spring 109 and the axis i. When the first connector 102 and the second connector 104 are assembled together, the step 122 abuts against the top of the snap-on spring 109 of the first connector 102 to prevent the second connector 104 from moving downward relative to the first connector 102. In some embodiments, the sleeve portion 112 includes at least one elastic leg 121. The distance between the outer surface of the elastic leg 121 and the axis i is approximately equal to the distance between the free end of the snap-on spring 109 and the axis i. This ensures that when the first connector 102 and the second connector 104 are assembled together, the outer surface of the elastic leg 121 is close to the top of the snap-on spring 109, thereby preventing the sleeve portion 112 from undergoing excessive radial displacement relative to the first connector 102. In this embodiment, the sleeve portion 112 includes three elastic legs 121, which are spaced circumferentially around the axis i. By providing the structure of the elastic legs 121, the sleeve portion 112 can also have a certain degree of elasticity, thereby controlling the insertion force and retention force between the first connector 102 and the second connector 104. It will be understood by those skilled in the art that, in other embodiments, the sleeve portion 112 may not include elastic legs, but may have a complete cylindrical shape, relying solely on the snap-fit ​​spring piece 109 of the first connector 102 to provide elasticity. In this way, the insertion force and the holding force between the first connector 102 and the second connector 104 can be controlled by simply designing the shape of the snap-fit ​​spring piece 109 as needed. The more specific structure of the sleeve portion 112 will be described in conjunction with Figure 2A and Figure 2B Provide a detailed description.

[0096] In this embodiment, the main body 111 is roughly cylindrical in shape, and includes a pair of connecting beams 113 and a pair of support beams 114 connected between the top and the bottom, the pair of connecting beams 113 are symmetrically arranged relative to the axis i, and the pair of support beams 114 are also symmetrically arranged relative to the axis i. The interior of the main body 111 defines a hollow retaining cavity 118. The main body 111 also includes a pair of retaining arms 117, one end of the pair of retaining arms 117 extends from the inner surface of the pair of connecting beams 113 to the retaining cavity 118. In some embodiments, each retaining arm 117 is connected to the connecting beam 113 by an integrally formed hub 115. Each retaining arm 117 includes a threaded engaging tooth 119, and the threaded engaging tooth 119 includes a plurality of teeth arranged along the axis i. Each tooth of the threaded engaging tooth 119 is capable of engaging with a pin 553 having an external thread (see Figure 5A and Figure 5B 553 are engaged with the main body 111 and the pin 553 in the retaining cavity 118. In the present embodiment, the pair of retaining arms 117 include a first retaining arm 117a and a second retaining arm 117b, and the two retaining arms 117 are arranged approximately symmetrically in the circumferential direction, and their threaded engagement teeth 119 have different heights, so that the pair of retaining arms 117 can engage with the external thread of the pin 553 in a larger axial range. It will be understood by those skilled in the art that the number of retaining arms 117 can be set to more or less so that there is a greater or lesser insertion force and retaining force between the main body 111 and the pin 553. It will be understood by those skilled in the art that in some embodiments, according to the different structures of the inserted pin, the retaining arms can also be set to other shapes and structures.

[0097] The bell mouth portion 123 is generally bell-shaped and is connected to the bottom of the main body portion 111. The bell mouth portion 123 also includes at least one notch 124, which can facilitate the bell mouth portion 123 to expand and deform to a certain extent. In this embodiment, the bell mouth portion 123 is provided with two notches 124, which are symmetrically arranged at the bottom of the bell mouth portion 123. Thus, the bell mouth portion 123 can abut against the body 554 of the second component 552 to be connected (see Figure 5BAs shown), on the one hand, an upward force is provided to the pin 553 of the second component 552, pressing the external thread of the pin 553 against the threaded engagement teeth 119 of the retaining arm 117. On the other hand, the bell-mouth portion 123 can accommodate the larger diameter head of the pin 553 when the pin 553 is inserted into the retaining cavity 118. It will be understood by those skilled in the art that the bottom edge of the bell-mouth portion 123 can be set to a suitable outer profile to match the different shapes of the body 554 of the second component 552. It will be understood by those skilled in the art that the bell-mouth portion is not necessary for this application. In some embodiments, the second connecting member may also not include the bell-mouth portion. In some embodiments, the second connecting member may include the bell-mouth portion, but does not include a notch.

[0098] It should be noted that the present application is not limited to the structure of the main body in this embodiment. The shape and structure of the main body can also be set accordingly according to the shape of the second component and the connection requirements.

[0099] In the present application, the first connecting member 102 and the second connecting member 104 of the fastening clip 100 can both be made of plastic material. The first connecting member 102 and the second connecting member 104 made of plastic material can have good elasticity and are easy to repeatedly disassemble and assemble.

[0100] Figure 2A and Figure 2B It is used to more clearly illustrate the internal structure of the fastening clip 100. Figure 2A is a cross-sectional view of the fastening clip 100 along line AA, Figure 2B FIG is a cross-sectional view of the fastening clip 100 along line BB. Figure 2A and Figure 2B As shown, the sleeve portion 112 of the second connector 104 has a hollow sleeve channel 228. In this embodiment, when the outer side of the elastic leg 121 of the sleeve portion 112 is squeezed, the elastic leg 121 can undergo a certain degree of elastic deformation into the sleeve channel 228.

[0101] The bottom of the step portion 122 of the sleeve portion 112 has a bottom inclined surface 241. The bottom inclined surface 241 is used to cooperate with the top of the snap-on spring 109 to prevent the second connector 104 from moving downward relative to the first connector 102 when the first connector 102 and the second connector 104 are assembled together. In this embodiment, the bottom inclined surface 241 is gradually inclined away from the axis i from the bottom to the top. By providing the bottom inclined surface 241 at the bottom of the step portion 122, when the operator removes the second connector 104 from the first connector 102, a component force is generated at the contact point between the bottom inclined surface 241 of the step portion 122 and the snap-on spring 109, which pushes the snap-on spring 109 to deform, thereby facilitating the separation of the first connector 102 and the second connector 104. The top of the step portion 122 has a guided surface 242. The guided surface 242 is used to cooperate with the bottom of the snap-on spring 109. In this embodiment, the guided surface 242 gradually tilts from bottom to top toward the axis i. By providing the guided surface 242 at the top of the step portion 122, when an operator inserts the second connector 104 into the first connector 102, a force component is generated at the contact portion between the guided surface 242 of the step portion 122 and the engaging spring 109, which pushes the engaging spring 109 to deform, thereby facilitating assembly of the first connector 102 and the second connector 104.

[0102] The top of the main body 111 of the second connector 104 has a shoulder 227 that extends horizontally from the connection between the bottom of the sleeve 112 and the main body 111. When the first connector 102 and the second connector 104 are assembled together, the shoulder 227 abuts against the lower surface of the bottom flange 103 of the first connector 102, preventing the second connector 104 from moving upward relative to the first connector 102. When the first connector 102 and the second connector 104 are assembled together, the step 122 and the shoulder 227 together ensure that the first connector 102 and the second connector 104 cannot move axially. By setting the outer diameter of the sleeve 112 below the step 122, the first connector 102 and the second connector 104 can be prevented from radial and circumferential displacement. As a result, when the first connector 102 and the second connector 104 are assembled together, they can maintain a snap-fit ​​connection.

[0103] The pair of connecting beams 113 and the pair of supporting beams 114 of the main body 111 are arranged at intervals from each other in the circumferential direction of the main body 111. The width of the connecting beam 113 is larger than the width of the supporting beam 114 (that is, the dimension in the circumferential direction), but the thickness (that is, the dimension in the radial direction) is smaller. This is because the connecting beam 113 is used to set the retaining arms 117a and 117b on the inner wall, and space needs to be reserved in thickness. In order to improve the strength of the retaining arms 117a and 117b, a larger width is required. The support beam 114 is used to provide strength to the main body 111, and space needs to be reserved for processing the retaining arms. Therefore, the thickness of the support beam 114 is larger and the width is smaller.

[0104] Figures 3A-3D FIG. 1 shows a more specific structure of the first connecting member 102. Figure 3A A perspective view showing the first connecting member 102 is shown, Figure 3B shows a top view of the first connecting member 102, Figure 3C A cross-sectional view of the first connecting member 102 along line CC is shown. Figure 3D FIG. 4 shows a cross-sectional view of the first connecting member 102 along line DD. Figures 3A-3D As shown, the inner wall of the neck portion 105 of the first connector 102 defines a central channel 108. Four snap-fit ​​springs 109 are disposed on the inner wall of the neck portion 105 at intervals along the circumferential direction.

[0105] In this embodiment, the sleeve portion 112 of the second connecting member 104 is inserted into the central passage 108 from bottom to top. Therefore, the bottom of the engaging spring 109 is connected to the inner wall of the neck portion 105 and extends obliquely from bottom to top toward the axis i, so that its top forms the free end closest to the axis i. When the engaging spring 109 is pushed outward, the engaging spring 109 can pivot about the bottom, causing the top to move away from the axis i, thereby freeing the insertion channel and the exit channel of the sleeve portion 112. In this embodiment, the bottom of each engaging spring 109 has a guide surface 332 extending obliquely from bottom to top toward the axis i. The guide surface 332 cooperates with the guided surface 242 at the top of the step portion 122 of the sleeve portion 112 to guide the sleeve portion 112 into the central passage 108. Furthermore, in this embodiment, the top of each engaging spring 109 has a top inclined surface 331 extending obliquely from bottom to top away from the axis i. The top inclined surface 331 mates with the bottom inclined surface 241 of the stepped portion 122 of the sleeve portion 112, so that when the second connector 104 is removed from the central passage 108, a component force is generated at the top of the engaging spring 109 to push the engaging spring 109 outward, causing the engaging spring 109 to deform, thereby allowing the sleeve portion 112 to be removed from the central passage 108. In this embodiment, the circumferential width of each engaging spring 109 gradually decreases from top to bottom, thereby reducing the force required to deform the engaging spring 109. In other embodiments, the top of the engaging spring 109 may not have an inclined surface shape, and can still generate a component force to push the engaging spring 109 to deform when the second connector 104 is removed.

[0106] In some actual assembly processes, although the first connector 102 and the second connector 104 are coaxially arranged, it is difficult to ensure that they are completely inserted axially and coaxially during assembly. Providing an axially extending guide bar 107 between the four engaging springs 109 ensures that even if there is an assembly error between the two, the guide bar 107 can guide the sleeve portion 112 into or out of the central channel 108. Furthermore, the guide bar 107 can absorb at least a portion of the shear force generated by the misalignment of the engaging springs 109 and the elastic legs 121, thereby protecting the engaging springs 109 from damage.

[0107] Figure 4A and Figure 4B FIG. 1 shows a more specific structure of the second connecting member 104. Figure 4A is a three-dimensional diagram of the second connecting member 104, Figure 4B is a top view of the second connecting member 104. Figure 4A and Figure 4BAs shown, in this embodiment, the sleeve portion 112 includes three elastic legs 121 spaced apart from each other, each of which has a stepped portion 122 disposed on its top. When the stepped portion 122 applies a thrust to the engaging spring 109 to engage the engaging spring 109, the elastic legs 121 may contract somewhat toward the axis i, thereby reducing the deformation force exerted on the engaging spring 109. In some embodiments, the elastic legs 121 may be omitted, allowing the sleeve portion 112 to be inserted into and removed from the central passage 108 as a whole.

[0108] In the present application, the snap-on springs 109 and the elastic legs 121 are set to different numbers, which can reduce the difficulty of assembling and disassembling the first connecting member 102 and the second connecting member 104, so that the operator does not need to fully align the snap-on springs 109 and the elastic legs 121.

[0109] Thus, during the insertion of the sleeve portion 112 into the central passage 108 along the axis i of the first connector 102, the step portion 122 is used to push away the engaging spring 109, forcing the engaging spring 109 to elastically deform toward the neck 105 to clear the insertion and exit paths of the sleeve portion 112. After the sleeve portion 112 is fully inserted into the central passage 108 of the first connector 102, the step portion 122 passes over the top of the engaging spring 109, freeing the engaging spring 109 from the pressure of the step portion 122 and allowing it to return to its original shape. The bottom of the step portion 122 abuts the top of the engaging spring 109, thereby engaging and connecting the first connector 102 and the second connector 104. Following the reverse process, the sleeve portion 112 of the second connector 104 can be removed from the central passage 108 of the first connector 102 along the axis i to disassemble the first connector 102 and the second connector 104.

[0110] Figure 5A and Figure 5B FIG. 5 shows the structure of the fastening clip assembly 550 including the fastening clip 100 when the fastening clip 100 is in an assembled state. Figure 5A A perspective view of the fastening clip assembly 550 is shown, Figure 5B The fastening clip assembly 550 is shown along Figure 1C The cross-sectional view after cutting along the AA line. Figure 5A and Figure 5BAs shown, the fastening clamp assembly 550 includes a first component 551, a second component 552, and the fastening clamp 100. The first component 551 is connected to the first connecting member 102 of the fastening clamp 100. In this embodiment, the first component 551 includes a generally circular flat portion 555 and an annular wall 556. The flat portion 555 has an opening 558 on its front side. The annular wall 556 is disposed around the circumferential edge of the flat portion 555. The flat portion 555 is engaged with the groove 106 of the first connecting member 102 through the opening 558 and is received by the groove 106. The second component 552 is connected to the second connecting member 104 of the fastening clamp 100. In this embodiment, the second component 552 includes a body 554 and a pin 553. The body 554 and the pin 553 are fixedly connected together. The pin 553 can be inserted from bottom to top into the retaining cavity 118 of the second connecting member 104 and engages with the retaining arm 117. The bell mouth portion 123 abuts the upper surface of the body 554. This secures the first component 551 and the second component 552. For example, the pin 553 is a welding stud having external threads that mate with the threaded teeth 119 of the retaining arm 117. The pin 553 engages with the threaded teeth 119 of the retaining arm 117 via the external threads, securing the pin 553 to the second connector 104.

[0111] In this application, the second component 552 is made of a metal material, such as a vehicle sheet metal. The body 554 is fixedly connected to the pin 553 by welding. The first component 551 is another plastic or metal component of the vehicle. The fastening clip 100 is made of a plastic material with a certain degree of elasticity.

[0112] Those skilled in the art will appreciate that the first component 551 and the second component 552 in the figure are merely schematic shapes. In practice, it is sufficient as long as the first component 551 includes the flat plate portion 555 and the second component 552 includes the pin 553 .

[0113] Figure 6A and Figure 6B FIG. 5 shows the structure of the fastening clip assembly 550 including the fastening clip 100 when the fastening clip 100 is in a disassembled state. Figure 6A A perspective view of the fastening clip assembly 550 is shown, Figure 6B The fastening clip assembly 550 is shown along Figure 1C The cross-sectional view after cutting along the AA line. Figure 6A and Figure 6BAs shown, when the operator pulls the first component 551 upward or pulls the second component 552 downward, the fastening clamp assembly 550 can be changed from the assembled state to the disassembled state. At this time, the bottom inclined surface 241 of the stepped portion 122 of the second connecting member 104 contacts the top inclined surface 331 of the engaging spring 109, generating a component force that pushes the engaging spring 109 to deform, causing the engaging spring 109 to deform, thereby allowing the sleeve portion 112 to be pulled out of the central channel 108. At this time, the first connecting member 102 and the first component 551 remain connected together, and the second connecting member 104 and the second component 552 remain connected together, but the first connecting member 102 and the second connecting member 104 separate, thereby separating the first component 551 from the second component 552.

[0114] By setting the retaining force between the first component 551 and the first connector 102, the retaining force between the first connector 102 and the second connector 104, and the retaining force between the second connector 104 and the second component 552 within reasonable ranges, the first connector 102 and the second connector 104 can be more easily disassembled than between other components, thereby preventing wear between the plastic fastening clip and the metal first and / or second components. As a specific example, the retaining force between the first component 551 and the first connector 102 can reach 600N, and the retaining force between the second connector 104 and the second component 552 can reach 600N. However, the retaining force between the first connector 102 and the second connector 104 is only 250N.

[0115] When an operator presses the first component 551 or the second component 552, the fastening clamp assembly 550 can be changed from a disassembled state to an assembled state. At this time, the guided surface 242 of the step portion 122 of the second connecting member 104 contacts the guiding surface 332 of the snap-on spring 109, generating a component force that pushes the snap-on spring 109 to deform, causing the snap-on spring 109 to deform, thereby allowing the sleeve portion 112 to be inserted into the central channel 108. After the step portion 122 passes over the top of the snap-on spring 109, the snap-on spring 109 is no longer subjected to the thrust and returns to its original state, causing the bottom inclined surface 241 of the step portion 122 to abut the top inclined surface 331 of the snap-on spring 109. The step portion 122 and the boss 227 of the second connecting member 104 jointly hold the first connecting member 102 in place relative to the second connecting member 104.

[0116] It should be noted that during the initial assembly of the fastening clip assembly 550, the first connecting member 102 and the second connecting member 104 of the fastening clip 100 are connected together. The assembled fastening clip assembly 550 is obtained by assembling the first component 551 with the first connecting member 102 and the second component 552 with the second connecting member 104. After the initial assembly of the fastening clip assembly 550 is complete, subsequent disassembly or assembly of the fastening clip assembly 550 is completed between the first connecting member 102 and the second connecting member 104 of the fastening clip 100.

[0117] Figures 7A-11B Detailed structures of a fastening clip 700 and a fastening clip assembly 1050 according to another embodiment of the present application are shown.

[0118] Figures 7A-7E FIG. 7 shows the structure of a fastening clip 700 according to another embodiment of the present application. Figure 7A A three-dimensional structural diagram of the fastening clip 700 is shown at an angle. Figure 7B An exploded view of the fastening clip 700 is shown at another angle. Figure 7C shows a top view of the fastening clip 700, Figure 7D shows a front view of the fastening clip 700, Figure 7E FIG. 7 shows a cross-sectional view of the fastening clip 700 along line EE. Figures 7A-7E As shown, similar to the fastening clamp 100, the fastening clamp 700 also includes a first connecting member 702 and a second connecting member 704, which are detachably connected together. The first connecting member 702 is used to connect to the first component 1051 to be fastened, and the second connecting member 704 is used to connect to the second component 1052 to be fastened (see Figure 10A and Figure 10B shown).

[0119] Similar to the first connector 102, the first connector 702 also includes a neck 705, a top flange 701, and a bottom flange 703. A groove 706 is formed between the top flange 701 and the bottom flange 703. The first connector 102 defines a central channel 708 extending along the axis i. At least one snap-on spring 709 and at least one guide bar 707 are connected to the inner wall of the central channel 708.

[0120] However, unlike the first connecting member 102, a first anti-rotation structure is provided between the first connecting member 702 and the first component 1051 to prevent the two from rotating relative to each other. After the first connecting member 702 is connected to the second connecting member 704, by preventing the first connecting member 702 and the first component 1051 from rotating relative to each other, the fastening clamp can be prevented from rotating as a whole relative to the first component 1051. In this embodiment, the first anti-rotation structure includes a top flange 701 that is no longer circular but polygonal with an angular shape, and an annular wall 1056 in the shape of a square ring. After the groove 706 of the first connecting member 702 receives the flat plate portion 1055 of the first component 1051, the polygonal top flange 701 can cooperate with the annular wall 1056 to prevent the first connecting member 702 and the first component 1051 from rotating relative to each other (see Figure 10A Those skilled in the art will appreciate that the first anti-rotation structure may include other anti-rotation structures, and the top flange 701 and the annular wall 1056 may be configured to have any matching shapes as long as they can prevent the first connector 702 and the first component 1051 from rotating relative to each other.

[0121] The first connector 702 further includes a cylindrical portion 761, which extends axially downward and outward from the bottom of the neck 705 to form a tapered shape. In this embodiment, the bottom opening of the cylindrical portion 761 is larger than the central passage 708. This allows the second connector 704 to be more easily inserted into the central passage 708 under the guidance of the cylindrical portion 761. This also increases the guiding distance during insertion, making it easier for operators to blindly connect the first connector 702 and the second connector 704 even in situations with limited vision.

[0122] A second anti-rotation structure is also included between the first connecting member 702 and the second connecting member 704 to prevent relative rotation between the two. In this embodiment, the second anti-rotation structure includes a first tooth portion 762 provided on the first connecting member 702 and a second tooth portion 763 provided on the second connecting member 704. The first tooth portion 762 and the second tooth portion 763 engage with each other to prevent relative rotation between the first connecting member 702 and the second connecting member 704. In this embodiment, the first tooth portion 762 is provided at the bottom edge of the barrel portion 761. The second tooth portion 762 is in the shape of a triangular tooth. Even if the second tooth portion 763 of the second connecting member 704 is not completely aligned with the first tooth portion 762 of the first connecting member 702, the triangular teeth can still guide them to rotate a short distance relative to each other to allow the two to engage.

[0123] Similar to the second connecting member 104, the second connecting member 704 includes a main body 711, a sleeve 712, and a bell-mouth portion 723. The sleeve 712 is connected to the top of the main body 711, and the top of the sleeve 712 has a step portion 722 for engaging with the snap-on spring 709 of the first connecting member 702. The bell-mouth portion 723 is connected to the bottom of the main body 711, and is provided with at least one notch 724 to facilitate deformation of the bell-mouth portion 723. The main body 711 includes a pair of connecting beams 713 and a pair of support beams 714, and a pair of retaining arms 717 are provided inside the main body 711. Similarly, in some embodiments, the second connecting member 704 may not include the bell-mouth portion 723, and the bell-mouth portion 723 may not include the notch 724.

[0124] However, in this embodiment, the sleeve portion 712 no longer includes three elastic legs, but is instead configured as a whole in a cylindrical shape. In this embodiment, the sleeve portion 712 no longer undergoes elastic deformation, relying solely on the snap-on spring 709 for elastic deformation. This prevents the sleeve portion from being unable to elastically deform inward when the pin 1053 of the second component 1052 is long. In this embodiment, elastic deformation is achieved solely by the snap-on spring 709, so that regardless of the length of the pin 1053, the sleeve portion 712 does not affect the insertion force and retention force. Furthermore, the main body 711 is no longer a straight cylinder, but instead includes a first main body 767 and a second main body 768 that are interconnected. The sleeve portion 712 is connected to the top of the first main body 767, and the bell-mouth portion 723 is connected to the bottom of the second main body 768. The shape of the first main body 767 matches that of the barrel 761 of the first connector 702, extending downward and outward from the bottom of the sleeve portion 712 to form a tapered shape. And in this embodiment, a pair of support platforms 765 are provided on the outer sides of the pair of connecting beams 713 of the second main body 768. The second tooth portion 763 is arranged on one of the support platforms 765 and protrudes upward from the top of the support platform 765. Thus, when the first connecting member 702 and the second connecting member 704 are connected, the cylinder portion 761 is sleeved on the outside of the first main body 767, and the first tooth portion 762 of the first connecting member 702 can engage with the second tooth portion 763 of the second connecting member 704, thereby preventing the first connecting member 702 and the second connecting member 704 from rotating relative to each other. As a specific example, the first tooth portion 762 of the first connecting member 702 is arranged as a circle arranged along the circumferential direction, while the second tooth portion 763 of the second connecting member 704 is arranged as an independent one. In this way, even if the first connecting member 702 and the second connecting member 704 have processing tolerances, the first tooth portion 762 and the second tooth portion 763 can be more easily engaged and matched. Continue to see Figure 7EAs shown, in this embodiment, the step portion 722 of the sleeve portion 712 has a bottom inclined surface 741 located at its bottom end and a guided surface 742 located at its top end. The bottom inclined surface 741 is used to push the snap-on spring 709 to deform when the second connector 104 is pulled out from the first connector 102 from top to bottom. The guided surface 742 is used to push the snap-on spring 709 to deform when the second connector 704 is inserted into the first connector 702 from bottom to top. And in this embodiment, the snap-on spring 709 no longer includes a top inclined surface that matches the bottom inclined surface 741, but includes a top plane 731, and the edge is a smooth shape. By adjusting the inclination angle and top shape of the snap-on spring 109, the insertion force and extraction force (or holding force) required for insertion and extraction between the second connector 704 and the first connector 702 can be adjusted. The applicant has found that under certain insertion and extraction forces, the snap-on spring piece 709 including the top flat surface 731 can be repeatedly inserted and extracted more times, and the service life of the snap-on spring piece 709 is longer.

[0125] Figure 8A and Figure 8B FIG. 7 shows a more specific structure of the first connecting member 702. Figure 8A A perspective view of the first connecting member 702 is shown, Figure 8B The first connecting member 702 is shown along Figure 7C The cross-sectional view of the EE line. Figure 8A and Figure 8B As shown, the first connecting member 702 includes four snap-fit ​​springs 709 and four guide bars 707. The shape of each guide bar 707 is the same as that of the guide bar 107, and the four guide bars 707 are evenly arranged on the inner wall of the central channel 708. Each snap-fit ​​spring 709 is arranged between adjacent guide bars 707. However, the shape of the snap-fit ​​spring 709 is not completely identical to that of the snap-fit ​​spring 109.

[0126] Specifically, the bottom end of each snap-on spring piece 709 is connected to the inner wall of the central channel 708 and extends obliquely from bottom to top toward the axis i to the top end, with the top end forming a free end. The bottom end of each snap-on spring piece 709 has a guide surface 832 for cooperating with the step portion 722 of the second connecting member 704. And the top end of each snap-on spring piece 709 has a top plane 731. And in this embodiment, the width of the bottom end of the snap-on spring piece 709 is greater than the width of the top end. Compared to the snap-on spring piece 109, the larger bottom end width of the snap-on spring piece 709 will increase the deformation force required for the snap-on spring piece 709 to deform, but will increase the service life of the snap-on spring piece 709 when repeatedly plugged in and out.

[0127] In this embodiment, the cylindrical portion 761 of the first connecting member 702 and the guiding surface 832 of the engaging spring 709 are substantially inclined at the same angle to facilitate guiding the sleeve portion 712 of the second connecting member 704 to be inserted into the central channel 708 .

[0128] The first tooth portion 762 extends axially downward from the bottom edge of the cylindrical portion 761 and comprises a continuous circle of triangular teeth arranged circumferentially. Each tooth has the same shape, and a triangular groove 871 is formed between two adjacent teeth for accommodating the teeth of the second tooth portion 763. As described above, the triangular teeth facilitate more accurate meshing of the first tooth portion 762 with the second tooth portion 763.

[0129] Figure 9A and Figure 9B FIG. 7 shows a more specific structure of the second connecting member 704. Figure 9A A perspective view showing the second connecting member 704 is shown, Figure 9B FIG. 4 shows a left side view of the second connecting member 704. Figure 9A and Figure 9B As shown, the second connecting member 704 includes a pair of support platforms 765a and 765b. The support platforms 765a and 765b are relatively arranged on the left and right sides of the main body 711 of the second connecting member 704, and are formed to protrude outward from the outer surfaces of the left and right sides of the main body 711. In this embodiment, the support platforms 765a and 765b are arranged on the left and right sides of the second body 768 of the main body 711. Thus, when the first connecting member 702 is connected to the second connecting member 704, the first body 767 of the second connecting member 704 is supported on the inner side of the cylindrical portion 761 of the first connecting member 702, and the support platforms 765a and 765b can support the first tooth portion 762 of the first connecting member 702.

[0130] The second tooth portion 763 is disposed on the support platform 765a, protruding upward from the upper surface of the support platform 765 and located in the middle of the support platform 765a. The second tooth portion 763 is configured to engage with the first tooth portion 762. In this embodiment, the second tooth portion 763 is also triangular in shape, having the same shape as the grooves formed between adjacent teeth of the first tooth portion 762, so that the second tooth portion 763 can engage with the first tooth portion 762.

[0131] Figure 10A and Figure 10B FIG. 1 shows the structure of the fastening clip assembly 1050 including the fastening clip 700 when the fastening clip 700 is in an assembled state. Figure 10A A perspective view of the fastening clip assembly 1050 is shown, Figure 10B The fastening clip assembly 1050 is shown along Figure 7C The cross-sectional view after cutting along the FF line. Figure 10A and Figure 10BAs shown, the fastening clip assembly 1050 includes a first component 1051, a second component 1052, and the fastening clip 700. The first component 1051 is connected to the first connector 702 of the fastening clip 700. In this embodiment, the first component 1051 includes a generally square flat portion 1055 and an annular wall 1056. The flat portion 1055 has an opening 1058 on its front side. The annular wall 1056 is disposed around the circumferential edge of the flat portion 1055. The flat portion 1055 is inserted into the groove 706 of the first connector 702 through the opening 1058 and is received by the groove 706. In this embodiment, the flat portion 1055 is generally square in shape, and the annular wall 1056 also forms a square annular groove. The flat portion 1055 is slightly larger than the top flange 701 of the first connector 702, so that the polygonal top flange 701 can be accommodated within the area enclosed by the annular wall 1056 but cannot rotate. Therefore, the first connecting member 702 cannot rotate relative to the first component 1051 .

[0132] The second component 1052 is connected to the second connector 704 of the fastening clamp 700. In this embodiment, the second component 1052 includes a body 1054 and a pin 1053, which are fixedly connected together. The pin 1053 can be inserted from the bottom up into the second connector 704 and engage with the retaining arm 717. The bell-mouth portion 723 abuts the upper surface of the body 1054. This allows the first component 1051 and the second component 1052 to be securely connected. As an example, the pin 1053 is a welding stud having external threads that mate with the threaded teeth of the retaining arm 717. The external threads of the pin 1053 engage with the threaded teeth of the retaining arm 717, thereby firmly connecting the pin 1053 to the second connector 704. In this embodiment, the length of the pin 1053 is approximately the same as the overall height of the second connector 704, and the middle portion of the pin 1053 is used to engage with the retaining arm 717. The top of the pin 1053 is generally retained in the sleeve portion 712. It should be noted that the inner wall of the sleeve portion 712 does not have teeth for engaging with the external thread of the pin 1053. The pin 1053 is engaged with the second connector 704 solely by the retaining arm 717. In this embodiment, the second connector 704 can be used to assemble a pin 1053 with a length ranging from the bottom of the retaining arm 717 to the top of the sleeve portion 712.

[0133] The barrel portion 761 of the first connecting member 702 is sleeved onto the exterior of the first main body 767 of the second connecting member 704, and the first tooth portion 762 of the first connecting member 702 abuts against the support platform 765 of the second connecting member 704, so that the second connecting member 704 cannot move upward relative to the first connecting member 702. In addition, the step portion 722 of the sleeve portion 712 abuts against the top of the clamping spring 709, so that when the second connecting member 704 is not subjected to a large extraction force, the second connecting member 704 cannot move downward relative to the first connecting member 702. In addition, the first tooth portion 762 of the first connecting member 702 meshes with the second tooth portion 763 of the second connecting member 704, so that the second connecting member 704 cannot rotate relative to the first connecting member 702. Through such a structure, the connection between the first connecting member 702 and the second connecting member 704 can remain relatively stable, forming the fastening clamp 700. Furthermore, since the first connecting member 702 can be firmly connected to the first component 1051 and the second connecting member 704 can be firmly connected to the second component 1052 , the fastening clip 700 can firmly connect the first component 1051 and the second component 1052 together.

[0134] Figure 11A and Figure 11B FIG. 1 shows the structure of the fastening clip assembly 1050 including the fastening clip 700 when the fastening clip 700 is in a disassembled state. Figure 11A A perspective view of the fastening clip assembly 1150 is shown, Figure 11B The fastening clip assembly 1150 is shown along Figure 7C The cross-sectional view after cutting along the FF line. Figure 11A and Figure 11B As shown, when the operator pulls the first component 1051 upward or pulls the second component 1052 downward, the fastening clamp assembly 1050 can be changed from the assembled state to the disassembled state. At this time, the bottom inclined surface 741 of the step portion 722 of the second connecting member 704 contacts the top flat surface 731 of the engaging spring 709, causing the engaging spring 709 to deform inward, thereby allowing the sleeve portion 712 to be pulled out of the central channel 708. At this time, the first connecting member 702 and the first component 1051 remain connected together, and the second connecting member 704 and the second component 1052 remain connected together, but the first connecting member 702 and the second connecting member 704 separate, thereby separating the first component 1051 from the second component 1052.

[0135] Similar to the fastening clamp assembly 550, by setting the retaining force between the first component 1051 and the first connecting member 702, the retaining force between the first connecting member 702 and the second connecting member 704, and the retaining force between the second connecting member 704 and the second component 1052 within a reasonable range, the first connecting member 702 and the second connecting member 704 can be made easier to disassemble than other components, thereby avoiding wear between the fastening clamp made of plastic and the first component and / or second component made of metal.

[0136] When an operator presses the first component 1051 or the second component 1052, the fastening clamp assembly 1050 can be changed from a disassembled state to an assembled state. At this point, the sleeve portion 712 of the second connector 704 is inserted into the barrel portion 761 of the first connector 702. After the guided surface 742 of the step portion 722 contacts the guide surface 832 of the snap-on spring 709, the guided surface 742 pushes the snap-on spring 709 to deform, allowing the sleeve portion 712 to be inserted into the central channel 708. After the step portion 722 passes over the top of the snap-on spring 709, the snap-on spring 709 is no longer subject to the thrust and returns to its original state, causing the bottom inclined surface 741 of the step portion 722 to abut the top flat surface 731 of the snap-on spring 709. The step portion 722 of the second connector 704 and the support platform 765 jointly hold the first connector 102 in place relative to the second connector 104.

[0137] The present application provides a fastening clamp comprising a first connecting member and a second connecting member that are detachably connected. When the fastening clamp connects two components, the first connecting member and the second connecting member are securely connected to the components, respectively. Furthermore, by removing the first and second connecting members to separate the two components, the fastening clamp of the present application can prevent wear between the metal component and the plastic fastening clamp. The fastening clamp of the present application is particularly suitable for attaching two components, at least one of which is made of metal.

[0138] The fastening clamp of the present application, by providing a matching shape of a sleeve and a snap-on spring, enables the first and second connecting members of the fastening clamp to have smaller dimensions, while maintaining insertion and extraction forces within the required range. The second connecting member of the fastening clamp of the present application includes a retaining arm structure that can provide a secure connection between the second connecting member and a pin having an external thread. This further prevents wear between the metal and plastic parts when the pin is made of a metal material. Furthermore, the fastening clamp of the present application is connected to the second component via a pin, such as a welding nail, eliminating the need to drill holes in the second component, simplifying the assembly process and reducing the difficulty of assembly.

[0139] Furthermore, the fastening clamp in some embodiments can better guide the first and second connecting members to be assembled together by providing matching cylindrical portions and first bodies on the first and second connecting members, and is particularly suitable for assembly occasions with poor vision.

[0140] Furthermore, in some embodiments, the fastening clamp includes cooperating anti-rotation structures, such as intermeshing teeth, on the first and second connectors to prevent relative rotation between the first and second connectors. Furthermore, in some embodiments, the fastening clamp further prevents relative rotation between the first connector and the first component.
