[0036] The present invention will be described in detail below with reference to the accompanying drawings and by way of examples.

[0037] The present invention provides a quick installation component for a back pad type ozone sheet, as shown in Figure 1 、 Figure 2 and Figure 3 structures. The installation component includes an insulating housing 1, a plug spring 2 and an ozone sheet 3; as shown in Figure 1 、 Figure 4 、 Figure 5 and Figure 6 structures, the insulating housing 1 can be a cuboid-shaped housing with an opening 5 provided on one side, forming a cavity for accommodating the plug spring 2 and the ozone sheet 3 inside, and the plug spring 2 and the ozone sheet 3 are installed in the insulating housing 1 through the opening 5; in order to facilitate the fixed installation of the insulating housing 1, a protruding fixed plate 18 can also be provided on the peripheral side of the insulating housing 1, and fixing holes are opened on the fixed plate 18;

[0038] As shown in Figure 4 、 Figure 5 and Figure 6 structures, two plug springs 2 arranged side by side are inserted into the insulating housing 1, and perforations 4 corresponding to each plug spring 2 are provided on the side wall of the insulating housing 1;

[0039] The bottom surface of the ozone sheet 3 is provided with pads corresponding to each plug spring 2, that is, two pads are provided on the bottom surface of the ozone sheet 3 for realizing electrical connection with the plug spring 2, and electrical connection between the cable 8 and the ozone sheet 3 is realized through the plug spring 2;

[0040] The ozone sheet 3 is snap-fitted into the opening 5 of the insulating housing 1, and the pads of the ozone sheet 3 are abutted against the tops of the corresponding plug springs 2; the ozone sheet 3 is also provided with discharge electrodes connected to the pads one by one. During actual use, an alternating current is generated by a power supply, and the alternating current acts between the two discharge electrodes through the sequential conduction of the cable 8, the plug spring 2, and the pads, thereby generating ozone;

[0041] As shown in Figure 7 、 Figure 8 and Figure 9As shown in the structure, the plug spring 2 is made of an elastic metal sheet, and at least two barbs 6 evenly distributed in the circumferential direction are arranged inside. The number of barbs 6 can be 3 - 5; the barbs 6 and the plug spring 2 can be an integrally formed structure or a separately formed structure; the ends of the barbs 6 are inclined outward; a gap 7 for threading the cable 8 is formed between the ends of at least two barbs 6. The width of the gap 7 is smaller than the diameter of the cable 8. The barbs 6 are used to clamp the cable 8 passing through the gap 7 and prevent the cable 8 from withdrawing. The material of the plug spring 2 can be stainless steel 301, stainless steel 304, stainless steel 316, phosphor bronze, beryllium copper, carbon steel spring steel or alloy spring steel.

[0042] In the above-mentioned back pad type ozone sheet quick installation assembly, the ozone sheet 3 is snap-fitted into the opening 5 of the insulating housing 1, so that the pad of the ozone sheet 3 abuts against the top of the corresponding plug spring 2. The plug spring 2 is made of an elastic metal sheet, and at least two barbs 6 distributed in the circumferential direction are arranged inside the plug spring 2. A gap 7 for threading the cable 8 is formed between the ends of the barbs 6. Since the width of the gap 7 is smaller than the diameter of the cable 8, when the cable 8 passes through the gap 7 between the barbs 6, the cable 8 can be clamped between the barbs 6, improving the friction force between the cable 8 and the barbs 6, thereby improving the connection strength between the cable 8 and the plug spring 2. Therefore, the above installation assembly fixes the wire harness through the barb 6 structure, realizes the quick plugging and unplugging of the wire harness, and fixes the ozone sheet 3, solving the problems of low connection efficiency, easy solder joint detachment, and insufficient fixed plugging force existing in the connection between the existing ozone sheet 3 and the power supply, and avoiding the problem of damage to the ozone sheet 3 during operation.

[0043] In a specific embodiment, as Figure 7 , Figure 8 and Figure 9 shown in the structure, the plug spring 2 includes a rectangular plug-in board 9 at the bottom and a connecting portion at the top; the plug-in board is arranged vertically and is fixedly connected to the bottom of the connecting portion; the barbs 6 are arranged on the plug-in board; as Figure 8 shown in the structure, three barbs 6 are partitioned inside the rectangular plug-in board 9, and the three barbs 6 are evenly distributed in the circumferential direction;

[0044] The connecting portion is a "7"-shaped structure, including a horizontal top plate 10 and an inclined plate 11 arranged obliquely; an arc transition is formed between the top plate 10 and the inclined plate 11, and a first included angle a is formed. The first included angle a is 25° - 60°; an arc transition is formed between the inclined plate 11 and the plug-in board, and a second included angle b is formed. The second included angle b is 100° - 150°;

[0045] As Figure 5 and Figure 6 shown in the structure, two slots 12 for plugging and matching with the plug-in board are arranged inside the insulating housing 1.

[0046] The insertion spring 2 forms a bent portion at the connection between the top plate 10 and the inclined plate 11, and at the connection between the inclined plate 11 and the rectangular plug-in plate 9 respectively. Two curvature bends are formed by the two bent portions respectively to provide an upward supporting force, so as to achieve a sufficiently stable and lasting contact between the ozone sheet 3 and the insertion spring 2 after assembly, and achieve the purpose of saving the assembly space. As Figure 7 shown in the structure, two convex points 13 are arranged on the top surface of the top plate 10, and the convex points 13 are electrically connected to the corresponding pads. The number of the convex points 13 can be 2-5, and the connection reliability with the pads of the ozone sheet 3 can be enhanced through the convex points 13.

[0047] The through hole 4 further includes an insertion spring throat 14 communicating with the slot 12, and the diameter of the insertion spring throat 14 is smaller than that of the through hole 4. As Figure 3 and Figure 5 shown in the structure, the insertion spring throat 14 is composed of a throat hole with a diameter smaller than that of the through hole 4 and a tapered hole connecting the throat hole and the through hole 4. One end of the tapered hole communicates with the through hole 4 and has the same diameter as the through hole 4, and the other end communicates with the throat hole and has the same diameter as the throat hole. Through the insertion spring throat 14 arranged on the insulating housing 1, after the cable 8 is inserted into the through hole 4 and is plugged and connected with the insertion spring 2, the cable 8 can be stably fixed. When the cable 8 is stretched, a reverse force is provided to prevent the cable 8 from being pulled out, ensuring the tensile strength of the cable 8.

[0048] As Figure 4 and Figure 5 shown in the structure, on the inner side wall of the insulating housing 1 on the side of the opening 5, upper and lower buckles 15 and 16 are arranged oppositely; the upper and lower buckles 15 and 16 are used to limit the ozone sheet 3 at the top of the ozone sheet 3. The ozone sheet 3 is jointly supported by the upper and lower buckles 15 and 16 and the insertion spring 2, so that while the ozone sheet 3 is limited, the stable and reliable contact between the ozone sheet 3 and the insertion spring 2 can be ensured.

[0049] As Figure 3 shown in the structure, the cable 8 includes a wire core 17 and an outer skin covering the outer peripheral side of the wire core 17. In order to ensure the reliable connection and power conduction between the cable 8 and the insertion spring 2, a cold pressing terminal or tinning treatment is provided at the end of the wire core 17. The exposed part of the wire core 17 can be a single-strand wire or a multi-strand wire; when the wire core 17 is a single-strand wire, the diameter of the wire core 17 is larger than the gap 7 surrounded by the plurality of barbs 6; when the wire core 17 is a multi-strand wire, the exposed end of the wire core 17 can be twisted, tinned, or both twisted and tinned at the same time to make it integrated, and the diameter of the converged wire core 17 is larger than the gap 7 surrounded by the plurality of barbs 6. The purpose of twisting and tinning can also increase the roughness of the wire core 17 part and improve the difficulty of pulling out the wire core 17.

[0050] When the end of the wire core 17 is a single-strand wire or a multi-strand wire, the end of the cable 8 can also be cold-pressed with a terminal. After cold-pressing the terminal, the end of the wire core 17 forms a diameter larger than the gap 7 surrounded by multiple barbs 6, so that it is not easy to pull out the cable 8 after insertion, improving the connection stability and reliability between the cable 8 and the plug spring 2.

[0051] In summary, the above are only the preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
