[0054] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation
[0055] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0056] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0057] To further illustrate the technical means and effects adopted by this application in achieving its intended purpose, the following detailed description of this application is provided in conjunction with the accompanying drawings and preferred embodiments.
[0058] Please see Figure 1The wire clamp 100 provided in this embodiment includes a first side arm 10, a bottom arm 50, a second side arm 30, and a top arm 70, which are sequentially bent and connected. The first side arm 10 and the second side arm 30 are disposed opposite each other, and the bottom arm 50 and the top arm 70 are disposed opposite each other. The first side arm 10 includes a slot portion 11 located at the end of the first side arm 10 away from the bottom arm 50. The top arm 70 includes an engaging portion 71 located at the end of the top arm 70 away from the second side arm 30. The engaging portion 71 engages with the slot portion 11 to form a closed annular structure around the first side arm 10, the second side arm 30, the bottom arm 50, and the top arm 70 for surrounding the wire.
[0059] Specifically, the first side arm 10 is bent and connected to the bottom arm 50, the bottom arm 50 is bent and connected to the second side arm 30, the second side arm 30 is bent and connected to the top arm 70, and the top arm 70 is fixed to the first side arm 10 by the engaging connection between the engaging part 71 and the engaging groove part 11.
[0060] A rotating part 80 is provided at the connection between the top arm 70 and the second side arm 30, allowing the top arm 70 to rotate relative to the second side arm 30 around the rotating part 80 as a fulcrum, thereby engaging with or disengaging from the first side arm 10. In this embodiment, the rotating part 80 can be a rounded structure with a thickness thinner than the top arm 70 and the second side arm 30, allowing the top arm 70 to bend and rotate relative to the second side arm 30 around the rotating part 80 as a fulcrum. In other embodiments, the rotating part 80 can also be a pivot structure, with the top arm 70 and the second side arm 30 rotatably connected via the pivot structure, allowing the top arm 70 to rotate relative to the second side arm 30. The specific structure of the rotating part 80 is not limited in this application.
[0061] Please refer to the following: Figure 1 and Figure 2 The slot portion 11 includes a receiving cavity 111. A slot 112 is provided on the side wall of the receiving cavity 111 away from the second side arm 30. The receiving cavity 111 is used to partially accommodate the engaging portion 71 so that the engaging portion 71 engages with the slot 112.
[0062] The engaging portion 71 includes an elastic portion 711, an engaging hook 713, and a push handle 715. The engaging hook 713 is located on the side of the elastic portion 711 away from the second side arm 30, and the push handle 715 is located at the end of the elastic portion 711 away from the second side arm 30. Specifically, the elastic portion 711 is a bent structure protruding towards the bottom arm 50. The engaging hook 713 is located on the side wall of the elastic portion 711 away from the second side arm 30. The elastic portion 711 can move the engaging hook 713 in a direction close to or away from the second side arm 30. The push handle 715 is located at the end of the bent structure of the elastic portion 711. The push handle 715 can compress the elastic portion 711 under the action of external force, thereby moving the engaging hook 713.
[0063] The engaging hook 713 is used to engage with the slot 112. Specifically, when the top arm 70 is engaged with the first side arm 10, the elastic part 711 is housed in the receiving cavity 111, and the elastic part 711 applies a force to the engaging hook 713 away from the second side arm 30, thereby engaging the engaging hook 713 into the slot 112. At this time, applying a force to the push handle 715 toward the second side arm 30 can drive the engaging hook 713 toward the direction closer to the second side arm 30, thereby disengaging from the engaging state with the slot 112, and thus releasing the engaging state between the top arm 70 and the first side arm 10.
[0064] The wire clamp 100 provided in this application embodiment sets the engagement state of the top arm 70 and the first side arm 10 by setting the push handle 715 and the elastic part 711. This allows the top arm 70 and the first side arm 10 to switch between the engagement and non-engaged states, thereby facilitating the insertion of wires into the wire clamp 100 in the non-engaged state and the fixing of wires in the engagement state.
[0065] The wire clamp 100 also includes an elastic arm 90, which is disposed between the first side arm 10 and the second side arm 30. One end of the elastic arm 90 is connected to the second side arm 30. The elastic arm 90 is used to fix the position of the wire when the wire clamp 100 surrounds the wire. Specifically, the elastic arm 90 has an arc-shaped protrusion 91 facing the top arm 70. When the wire is housed in the wire clamp 100, the elastic arm 90 can abut against the wire, thereby fixing the position of the wire in the wire clamp 100.
[0066] A first fixing part 20 is provided on the first side arm 10. The first fixing part 20 includes a first fixing wing 21 and a second fixing wing 23, which are spaced apart in the first direction X. Specifically, the first fixing wing 21 and the second fixing wing 23 are protruding structures extending from the first side arm 10 away from the second side arm 30. The first direction X is the axial direction of the closed annular structure formed by the first side arm 10, the second side arm 30, the bottom arm 50, and the top arm 70. That is, the first direction X is the thickness direction of the wire clamp 100, or the thickness direction of the sheet metal part 210 when the wire clamp 100 is mounted on the sheet metal part 210. The first fixing wing 21 and the second fixing wing 23 are spaced apart in the first direction X, so that when the wire clamp 100 is mounted on the sheet metal part 210, it engages with the sheet metal part 210, thereby fixing the relative position of the wire clamp 100 and the sheet metal part 210 in the first direction X. In this embodiment, the distance between the first fixing wing 21 and the second fixing wing 23 in the first direction X is the same as the thickness of the sheet metal part 210. In other embodiments, the distance between the first fixing wing 21 and the second fixing wing 23 in the first direction X and the thickness of the sheet metal part 210 may also have a certain tolerance, and this application does not impose any restrictions on this.
[0067] In this embodiment, there are two first fixing wings 21 and one second fixing wing 23. The first fixing wings 21 are spaced apart in the extending direction of the first side arm 10, and the second fixing wing 23 is located between the two first fixing wings 21 in the extending direction of the first side arm 10. This allows for better fixation of the wire clamp 100 when it is mounted on the sheet metal part 210. In other embodiments, the number and arrangement of the first fixing wings 21 and the second fixing wings 23 can be set according to specific needs, and this application does not impose any restrictions on this.
[0068] The first fixing part 20 also includes a first fixing post 25, which protrudes from the side of the first side arm 10 away from the second side arm 30. The first fixing post 25 is used to engage with the sheet metal part 210, thereby fixing the relative position of the wire clamp 100 and the sheet metal part 210. Specifically, the sheet metal part 210 has a receiving groove 211 for accommodating the wire clamp 100, and a limiting groove 212 matching the first fixing post 25 is formed on the side wall of the receiving groove 211. When the wire clamp 100 is fixed in the receiving groove 211, the first fixing post 25 engages with the limiting groove 212, thereby fixing the position of the wire clamp 100 in the extending direction of the first side arm 10.
[0069] A second fixing part 40 is provided on the second side arm 30. The second fixing part 40 includes a third fixing wing 41 and a fourth fixing wing 43, which are spaced apart in the first direction X. Specifically, the third fixing wing 41 and the fourth fixing wing 43 are protrusions extending from the second side arm 30 away from the first side arm 10. The third fixing wing 41 and the fourth fixing wing 43 are spaced apart in the first direction X, so that when the wire clamp 100 is placed on the sheet metal part 210, it engages with the sheet metal part 210, thereby fixing the relative position of the wire clamp 100 and the sheet metal part 210 in the first direction X. In this embodiment, the distance between the third fixing wing 41 and the fourth fixing wing 43 in the first direction X is the same as the thickness of the sheet metal part 210. In other embodiments, the distance between the third fixing wing 41 and the fourth fixing wing 43 in the first direction X and the thickness of the sheet metal part 210 may have a certain tolerance, which is not limited in this application.
[0070] In this embodiment, there are two third fixing wings 41 and one fourth fixing wing 43. The third fixing wings 41 are spaced apart in the extending direction of the second side arm 30, and the fourth fixing wing 43 is located between the two third fixing wings 41 in the extending direction of the second side arm 30. This allows for better fixation of the wire clamp 100 when it is mounted on the sheet metal part 210. In other embodiments, the number and arrangement of the third fixing wings 41 and the fourth fixing wings 43 can be set according to specific needs, and this application does not impose any restrictions on this.
[0071] The second fixing part 40 also includes a second fixing post 45, which protrudes from the side of the second side arm 30 away from the first side arm 10. The second fixing post 45 is used to engage with the sheet metal part 210, thereby fixing the relative position of the wire clamp 100 and the sheet metal part 210. Specifically, the sheet metal part 210 has a receiving groove 211 for accommodating the wire clamp 100, and a limiting groove 212 matching the second fixing post 45 is provided on the side wall of the receiving groove 211. When the wire clamp 100 is fixed in the receiving groove 211, the second fixing post 45 engages with the limiting groove 212, thereby fixing the position of the wire clamp 100 in the extending direction of the second side arm 30.
[0072] A third fixing part 60 is provided on the bottom arm 50, which includes a fifth fixing wing 61 and a sixth fixing wing 63, which are spaced apart in the first direction X. Specifically, the fifth fixing wing 61 and the sixth fixing wing 63 are protrusions extending from the bottom arm 50 away from the top arm 70. The spaced-apart arrangement of the fifth fixing wing 61 and the sixth fixing wing 63 in the first direction X allows them to engage with the sheet metal part 210 when the wire clamp 100 is mounted on it, thereby fixing the relative position of the wire clamp 100 and the sheet metal part 210 in the first direction X. In this embodiment, the distance between the fifth fixing wing 61 and the sixth fixing wing 63 in the first direction X is the same as the thickness of the sheet metal part 210. In other embodiments, the distance between the fifth fixing wing 61 and the sixth fixing wing 63 in the first direction X and the thickness of the sheet metal part 210 may have a certain tolerance, which is not limited in this application.
[0073] In this embodiment, there are two fifth fixing wings 61 and one sixth fixing wing 63. The fifth fixing wings 61 are spaced apart in the extending direction of the bottom arm 50, and the sixth fixing wing 63 is located between the two fifth fixing wings 61 in the extending direction of the bottom arm 50. This allows for better fixation of the wire clamp 100 when it is mounted on the sheet metal part 210. In other embodiments, the number and arrangement of the fifth fixing wings 61 and the sixth fixing wings 63 can be set according to specific needs, and this application does not impose any restrictions on this.
[0074] The wire clamp 100 provided in this application embodiment can fix the relative position of the wire clamp 100 and the sheet metal part 210 in six degrees of freedom by providing a first fixing part 20, a second fixing part 40 and a third fixing part 60, thereby fully fixing the wire clamp 100 on the sheet metal part 210.
[0075] The wire clamp 100 provided in this embodiment of the application, by setting the top arm 70 and the first side arm 10 to form a closed structure through engagement, can accommodate the wire in the wire clamp 100. By setting the first fixing part 20, the second fixing part 40 and the third fixing part 60, the wire clamp 100 can be fixed to the sheet metal part 210, thereby fixing the wire to the sheet metal part 210. The wire clamp 100 has a simple structure, which avoids damage to the wire by the sheet metal part 210 and eliminates the need for other processes on the sheet metal part 210 or the wire, thus improving assembly efficiency.
[0076] Please see Figure 3 This application also provides an electronic device 200, which includes a sheet metal part 210, a wire 230, and a wire clamp 100 as described in the above embodiments. The sheet metal part 210 has a receiving groove 211, the wire 230 is disposed on the sheet metal part 210, and the wire clamp 100 is disposed on the receiving groove 211 for fixing the wire 230.
[0077] Specifically, the wire clamp 100 is engaged with the receiving groove 211, and the wire 230 is housed in the wire clamp 100. By fastening the top arm 70 of the wire clamp 100 to the first side arm 10, the wire 230 can be fixed in the wire clamp 100, and the elastic arm 90 can abut against the wire 230, thereby fixing the position of the wire 230.
[0078] The electronic device 200 provided in this application embodiment uses the wire clamp 100 as described in the above embodiment to fix the wire 230 to the sheet metal part 210. This avoids damage to the wire 230 by the sheet metal part 210 and eliminates the need for additional fixing or anti-damage processes for the sheet metal part 210 and the wire 230. This reduces the number of operation steps and improves assembly efficiency. Furthermore, by opening a receiving groove 211 on the sheet metal part 210, the space occupied by organizing the wire 230 can be reduced, which helps to improve space utilization.
