For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] A power plug is a device that connects an electrical device to a power source. Current power plugs and springs are usually connected to a single side of a circuit board, which may cause problems such as uneven pressure on the circuit board. In addition, due to the limited internal space of the power plug, the existing connection structure between the spring and the circuit board occupies a large space, which easily leads to the spacing between the spring and other electrical components not meeting product assembly requirements and safety requirements.

[0037] Based on the above questions, please refer to Figures 1 to 3 The embodiment of the utility model provides a plug 1, which has a compact structure and can solve the problems of cumbersome welding and wire management processes and low labor efficiency, and can meet the safety requirements and product assembly requirements in the limited space of the plug 1.

[0038] The plug 1 includes a shell 20, a pin 30, a circuit board 40 and a spring 10. A fixing plate 60 is provided inside the shell 20, and the spring 10 and the pin 30 are provided below the fixing plate. The circuit board 40 is provided above the fixing plate 60. The clamping body of the spring 10 abuts against the circuit board 40 through a channel on the fixing plate 60 to achieve electrical connection.

[0039] Furthermore, the plug 1 also includes a secondary spring sheet 50 , the number of the pins 30 is two, the two pins 30 are respectively connected to the spring sheet 10 and the secondary spring sheet 50 , the secondary spring sheet 50 is spaced apart from the spring sheet 10 , and the secondary spring sheet 50 and the spring sheet 10 clamp the circuit board 40 together.

[0040] In this embodiment, the two pins 30 are respectively connected to the L-level and N-level circuits, so the spring clip 10 and the secondary spring clip 50 are L / N-level spring clips 10, and the conductive function is achieved by connecting the spring clip 10 and the secondary spring clip 50 to the circuit board 40; and the secondary spring clip 50 and the spring clip 10 are arranged, especially so that the connection part between the secondary spring clip 50 and the circuit board 40 is spaced from the connection part between the spring clip 10 and the circuit board 40 to meet the design requirements.

[0041] For details, please continue to read Figures 3 to 6 The spring piece 10 includes a main body 100 , a first clamping body 200 and a second clamping body 300 .

[0042] The main body 100 is used to connect with the pin 30 , the first clamping body 200 is connected with the end of the main body 100 , the second clamping body 300 is connected with the side of the main body 100 , and the first clamping body 200 and the second clamping body 300 are used together to abut against both sides of the circuit board 40 .

[0043] In this embodiment, a first clamping body 200 and a second clamping body 300 are provided on the main body 100 to jointly clamp the circuit board 40, so that the spring piece 10 and the circuit board 40 are in contact and conductive by double-sided clamping. This can not only effectively fix the circuit board 40 and prevent it from tilting, but also ensure that the spring piece 10 and the circuit board 40 are stably connected, thereby ensuring good conductive performance. Moreover, by connecting the first clamping body 200 to the end of the main body 100 and the second clamping body 300 to the side of the main body 100, the structure of the spring piece 10 can be effectively simplified, and the overall size of the spring piece 10 can be reduced, thereby meeting safety requirements and product assembly requirements.

[0044] It should be noted that in order to meet the requirements of the double-sided clamping mechanism, the existing spring clip 10 is usually provided with an extension portion on the side of the main body, and clamping portions are provided on both sides of the extension portion. This will make the structure of the spring clip 10 more complicated and make the space occupied by the spring clip 10 larger. Therefore, this embodiment achieves the purpose of simplifying the structure of the spring clip 10 and reducing its size by connecting the first clamping body 200 to the end of the main body 100 and the second clamping body 300 to the side of the main body 100.

[0045] Optionally, the circuit board 40 may be a PCBA circuit board 40 .

[0046] In addition, the first clamping body 200 abuts against the first side wall 610 of the channel on the fixed plate 60, the second clamping body 300 abuts against the second side wall 620, the first side wall 610 is adjacent to the second side wall 620, and the second side wall 620 is connected to the third side wall 630. In other words, the first side wall 610, the second side wall 620 and the third side wall 630 together form a channel.

[0047] In this embodiment, the distance between the circuit board 40 and the first side wall 610 is smaller than the distance between the circuit board 40 and the third side wall 630 .

[0048] In detail, the distance between the first clamping body 200 and the adjacent side wall of the housing 20 is smaller than the distance between the second clamping body 300 and the adjacent side wall of the housing 20 .

[0049] In this embodiment, the side walls of the shell 20, the first side wall 610 and the third side wall 630 of the channel, and the circuit board 40 are arranged in parallel, and are all arranged perpendicularly to the main body 100; it can be understood that the second side wall 620 is also arranged perpendicularly to the main body 100, and is arranged perpendicularly to the side walls of the shell 20, the first side wall 610 and the third side wall 630 of the channel, and the circuit board 40.

[0050] It should be noted that the side wall of the housing 20 here refers specifically to the side wall of the first clamping body 200 adjacent to the housing 20 .

[0051] Through the above arrangement, the internal space of the plug can be arranged reasonably, and the structure of the spring piece 10 can be reasonable, which can effectively reduce the space occupied by the spring piece 10 inside the plug 1.

[0052] Furthermore, the first clamping body 200 includes a first connecting section 210 and a first clamping section 220 connected to each other, and the first connecting section 210 is connected to the main body 100 .

[0053] The second clamping body 300 includes a second connecting section 310 , a third connecting section 320 and a second clamping section 330 which are connected in sequence. The second connecting section 310 is connected to the body 100 , and the first clamping section 220 and the second clamping section 330 are arranged opposite to each other.

[0054] In this embodiment, since the first connecting section 210 is connected to the end of the main body 100 and the second connecting section 310 is connected to the side of the main body 100, the plane where the first connecting section 210 and the second connecting section 310 are located is vertically arranged; and in order to ensure that the first clamping section 220 and the second clamping section 330 can be arranged relative to each other, a third connecting section 320 connected to the second connecting section 310 is also arranged on the top side of the second connecting section 310, and the second clamping section 330 is connected to the third connecting section 320, so that the first clamping section 220 and the second clamping section 330 are arranged relative to each other.

[0055] Furthermore, in a direction parallel to the main body 100 , the distance from the abutment position between the first clamping section 220 and the circuit board 40 to the farthest position of the first connecting section 210 from the circuit board 40 is smaller than the distance from the abutment position between the second clamping section 330 and the circuit board 40 to the farthest position of the second connecting section 310 from the circuit board 40 .

[0056] That is, the clamping body is arranged at one end of the body 100 , which can reduce the width of the body 100 and thus reduce the volume of the spring 10 , compared with the structure in which the clamping body is arranged at the side of the body 100 .

[0057] Described from another perspective, the horizontal projections of the first clamping body 200 and the second clamping body 300 are located within the plane of the main body 100, that is, the projections of the first clamping body 200 and the second clamping body 300 on the main body 100 overlap with the main body 100, thereby preventing the first clamping body 200 and the second clamping body 300 from extending outside the main body 100 and causing the spring 10 to occupy a large space.

[0058] Furthermore, the first connecting section 210 and the second connecting section 310 are both arranged vertically to the main body 100, the third connecting section 320 is parallel to the main body 100, and the second clamping section 330 is connected to the third connecting section 320 near the side of the first clamping section 220, so that the first clamping section 220 and the second clamping section 330 are arranged relative to each other, which facilitates the first clamping section 220 and the second clamping section 330 to jointly clamp the circuit board 40.

[0059] In this embodiment, the first connecting section 210, the first clamping section 220, the second connecting section 310, the third connecting section 320 and the second clamping section 330 are integrally formed with the body 100 and are formed by a bending process, which not only simplifies the process but also makes the overall structural strength of the spring piece 10 high.

[0060] Furthermore, the first clamping section 220 includes a first guide portion 221 and a first clamping portion 222, one end of the first guide portion 221 is connected to the first connecting section 210, and the other end is connected to the first clamping portion 222;

[0061] The second clamping section 330 includes a second guide portion 331 and a second clamping portion 332, one end of the second guide portion 331 is connected to the third connecting section 320, and the other end is connected to the second clamping portion 332, and the spacing between the first guide portion 221 and the second guide portion 331 gradually decreases in the direction toward the clamping portion, so that the first clamping section 220 and the second clamping section 330 are jointly in an M shape.

[0062] In this embodiment, the first clamping portion 222 and the second clamping portion 332 are used to abut against both sides of the circuit board 40. Therefore, by setting the first guide portion 221 and the second guide portion 331 away from the clamping portion in a large distance, the circuit board 40 can be easily inserted between the first guide portion 221 and the second guide portion 331 during the assembly process, and can smoothly abut against the first clamping portion 222 and the second clamping portion 332 along the extension direction of the first guide portion 221 and the second guide portion 331.

[0063] Moreover, the above design can also make the first clamping section 220 and the second clamping section 330 have good elastic force and holding force.

[0064] In detail, the maximum distance between the first guide portion 221 and the second guide portion 331 is A, wherein A is 2.2 mm to 2.8 mm.

[0065] In this embodiment, the maximum distance between the first guide portion 221 and the second guide portion 331 can be 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm and 2.8mm. Of course, the maximum distance between the first guide portion 221 and the second guide portion 331 can also be other values, which are not specifically limited here.

[0066] Optionally, the maximum distance between the first guide portion 221 and the second guide portion 331 is 2.5 mm.

[0067] In detail, the distance between the first clamping portion 222 and the second clamping portion 332 is B, where B is 0.2 mm to 0.6 mm.

[0068] In this embodiment, the distance between the first clamping portion 222 and the second clamping portion 332 can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm and 0.6 mm. Of course, the distance between the first clamping portion 222 and the second clamping portion 332 can also be other values, which are not specifically limited here.

[0069] Furthermore, the thickness of the circuit board 40 is greater than the distance between the first clamping portion 222 and the second clamping portion 332, and is smaller than the maximum distance between the first guide portion 221 and the second guide portion 331, so that the first clamping body 200 and the second clamping body 300 have an interference fit with the circuit board 40, that is, the first clamping portion 222 and the second clamping portion 332 have an interference fit with the circuit board 40.

[0070] In this embodiment, the first clamping portion 222 and the second clamping portion 332 are interference-fitted with the circuit board 40 , thereby ensuring that the spring sheet 10 effectively clamps the circuit board 40 , thereby providing the plug 1 with good conductive performance.

[0071] Furthermore, the first clamping section 220 also includes a first extension portion 223, which is connected to the first clamping portion 222; the second clamping section 330 also includes a second extension portion 333, which is connected to the second clamping portion 332, and the distance between the first extension portion 223 and the second extension portion 333 gradually increases in the direction away from the clamping portion.

[0072] In this embodiment, a first extension portion 223 connected to the first clamping portion 222 and a second extension portion 333 connected to the second clamping portion 332 are provided, and the spacing between the first extension portion 223 and the second extension portion 333 gradually increases in a direction away from the clamping portions. When the circuit board 40 is removed from the first clamping portion 222 and the second clamping portion 332, the circuit board 40 can be prevented from being stuck by the first clamping portion 222 or the second clamping portion 332, thereby facilitating maintenance or replacement of parts.

[0073] In summary, the utility model provides a spring clip 10 and a plug 1, by arranging a first clamping body 200 and a second clamping body 300 on the main body 100 to jointly clamp the circuit board 40, so that the spring clip 10 and the circuit board 40 are in contact and conductive by double-sided clamping, which can not only effectively fix the circuit board 40 and prevent it from tilting, but also ensure that the spring clip 10 and the circuit board 40 are stably connected, thereby ensuring good conductive performance; moreover, by connecting the first clamping body 200 to the end of the main body 100 and the second clamping body 300 to the side of the main body 100, the structure of the spring clip 10 can be effectively simplified, and the overall size of the spring clip 10 can be reduced, thereby meeting safety requirements and product assembly requirements.

[0074] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
