DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0041] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0042] The push-pull test tooling provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0043] like Figure 1 , Figure 2 , Figures 6 to 8 As shown, the embodiment of the present application provides a filter, including an integrated bracket 210 , a receiving groove 211 is formed through the integrated bracket 210 , a nanocrystalline magnetic ring 240 is provided in the receiving groove 211 , and a copper bus 220 is passed through the nanocrystalline magnetic ring 240 .

[0044] The two side ends of the copper busbar 220 with respect to the nanocrystalline magnetic ring 240 are respectively fixedly connected to the integrated bracket 210 . A PCB board 270 is also fixedly disposed on the integrated bracket 210 , and a capacitor 250 is fixedly disposed on the PCB board 270 .

[0045] The integrated bracket 210 is configured to be integrally injection-molded on the copper bus 220 , and is fixedly connected to the nanocrystalline magnetic ring 240 via silicone.

[0046] In an embodiment of the present application, the above-mentioned filter is adopted. After the copper busbar 220 is inserted into the nanocrystalline magnetic ring 240, an integrated bracket 210 is directly injection molded on the copper busbar 220, which greatly improves the integrity of the device. Not only is the processing efficiency high, but also the adverse effects of the traditional split bracket structure on the nanocrystalline magnetic ring 240 during assembly are avoided. The overall structural accuracy of the device is higher, and the working stability of the device is effectively guaranteed.

[0047] In a preferred embodiment, Figures 6 to 8 As shown, the integrated bracket 210 is provided with a cavity communicating with the receiving groove 211 , and the PCB board 270 is fixed on the inner wall of the cavity of the receiving groove 211 by fixing screws 260 .

[0048] The capacitor 250 is located in the cavity of the accommodating groove 211 . A silicone layer is also provided in the cavity of the accommodating groove 211 . The capacitor 250 and the nanocrystalline magnetic ring 240 are fixedly connected to the integrated bracket 210 via the silicone layer.

[0049] It can be understood that after the integrated bracket 210, the nanocrystalline magnetic ring 240, the PCB board 270, and the capacitor 250 are assembled, in order to ensure the stability of the device during operation, silicone is poured into the cavity of the accommodating groove 211. After solidification, the silicone realizes a fixed connection between the capacitor 250, the nanocrystalline magnetic ring 240 and the integrated bracket 210, thereby ensuring the stability of the relative positions between the components during the operation of the device.

[0050] In a preferred embodiment, Figures 6 to 8 As shown, a cover plate 230 is detachably provided on the end surface of the integrated bracket 210 away from the PCB board 270 . The cover plate 230 is located at a corresponding position of the nanocrystalline magnetic ring 240 and can close the corresponding side opening of the accommodating groove 211 .

[0051] In a preferred embodiment, Figures 6 to 8 As shown, a clamping plate is fixedly provided on the end surface of the cover plate 230 close to the integrated bracket 210 , and a buckle capable of engaging with the clamping plate on the cover plate 230 is provided on the inner wall of the accommodating groove 211 .

[0052] The cover plate 230 can be detachably connected to the integrated bracket 210 through the clamping structure between the cover plate 230 and the inner wall of the receiving groove 211 .

[0053] It is understandable that the connection form between the cover plate 230 and the integrated bracket 210 is not limited to the above-mentioned one, as long as the cover plate 230 can seal the corresponding side opening of the receiving groove 211, which will not be elaborated here.

[0054] In a preferred embodiment, Figure 7 , Figure 8 As shown, a protection box 241 is fixedly disposed on one end surface of the nanocrystalline magnetic ring 240 in the axial direction.

[0055] It is understandable that the protective box 241 can fix the residues generated during the operation of the nanocrystalline magnetic ring 240, thereby further improving the overall working stability of the device.

[0056] In a preferred embodiment, Figure 1 , Figure 2 , Figures 6 to 8 As shown, two copper bars 220 are provided which are parallel to each other. The two copper bars 220 respectively pass through the nanocrystalline magnetic ring 240 and are fixedly connected to the integrated bracket 210 .

[0057] In a preferred embodiment, Figure 7 , Figure 8As shown, two PCB boards 270 are provided which are parallel to each other. The two PCB boards 270 are respectively located on two sides of the axial direction of the nanocrystalline magnetic ring 240 and are fixedly connected to the receiving groove 211 by fixing screws 260 .

[0058] A plurality of capacitors 250 are respectively welded and fixed on the two PCB boards 270 .

[0059] It is understandable that the fixed connection method between the PCB board 270 and the capacitor 250 is not limited to the above one, as long as the fixed connection between the two can be achieved, which will not be elaborated here.

[0060] In a preferred embodiment, Figure 1 , Figure 2 , Figures 6 to 8 As shown, a plurality of mounting holes 212 are formed through the integrated bracket 210 , and the integrated bracket 210 is fixedly connected to the mounting frame by bolts through the mounting holes 212 .

[0061] In a preferred embodiment, Figure 8 As shown, a grounding piece 280 connected to the PCB board 270 is also fixedly provided on the integrated bracket 210 .

[0062] The grounding member 280 has a first guide head, a second guide head and a guide piece connecting the first guide head and the second guide head, wherein the first guide head is connected to the PCB board 270, and the second guide head is embedded in the mounting hole 212 and can be fixedly connected to the mounting frame by bolts.

[0063] In a preferred embodiment, the integrated bracket 210 is configured to be integrally injection molded on the copper bus 220 and the grounding member 280 .

[0064] It is understandable that directly injecting the integrated bracket 210 on the grounding piece 280 and the copper busbar 220 can simplify the subsequent assembly of the grounding piece 280, further improve the overall processing efficiency of the device, and ensure the position accuracy, so that it is not easy to fall off during operation.

[0065] like Fig.14 As shown, the embodiment of the present application also provides a processing method for a filter, comprising:

[0066] S1. The copper bar passes through the nanocrystalline magnetic ring, and the copper bar, the nanocrystalline magnetic ring, and the grounding piece are positioned in the injection mold;

[0067] S2, isolating the nanocrystalline magnetic ring separately, and forming an integrated bracket by injection molding on the copper bus and grounding piece;

[0068] S3, releasing the isolation of the nanocrystalline magnetic ring and demoulding;

[0069] S4. Solder the capacitor on the PCB and lock the PCB on the integrated bracket on the copper busbar;

[0070] S5. Install the cover plate on the integrated bracket and seal it with glue;

[0071] S6. Pour silicone into the cavity of the integrated bracket to fix the nanocrystalline magnetic ring and the capacitor.

[0072] In an embodiment of the present application, the above-mentioned processing method is adopted. Since the characteristic of the nanocrystalline magnetic ring is that the inductance is greatly attenuated after being subjected to external force, the nanocrystalline magnetic ring is separately isolated during the injection molding process of the integrated bracket, thereby protecting the nanocrystalline magnetic ring from the pressure of glue punching during the injection molding process, and ensuring the working performance of the nanocrystalline magnetic ring while realizing the integrated processing of the filter, thereby improving the overall quality of the filter.

[0073] It can be understood that in step S1, since there is no installation position interference between the grounding part and other components, the grounding part can also be arranged to be installed on an integrated bracket together with the PCB board after injection molding and demolding, that is, the grounding part is an independent assembly component. At this time, the structural complexity of the injection mold can be reduced, and the processing cost of the injection molding process can be reduced. However, additional assembly time will be required later. The specific implementation plan is set based on actual needs and will not be elaborated here.

[0074] In a preferred embodiment, in step S2, the isolation method of the nanocrystalline magnetic ring can adopt a physical isolation method, that is, during the injection molding process, the injection mold forms an independent cavity for accommodating the nanocrystalline magnetic ring, and at this time, the integrated bracket is injection molded outside the independent cavity, thereby avoiding the influence of the filling pressure on the performance of the nanocrystalline magnetic ring.

[0075] It is understandable that since a copper bar is inserted into the nanocrystalline magnetic ring, the independent cavity formed by the injection mold needs to have a clearance space for the copper bar. At the same time, the sealing of the independent cavity should be ensured to prevent the injection colloid outside the independent cavity from flowing into the independent cavity through the clearance gap at the copper bar position.

[0076] In a preferred implementation, in step S4, the connection method between the PCB board and the capacitor is not limited to the above one, as long as the connection between the two can be achieved, which will not be described in detail here.

[0077] In a preferred embodiment, in step S4, after the PCB board is locked on the integrated bracket, the grounding piece on the integrated bracket is connected to the PCB board at a corresponding position.

[0078] In a preferred embodiment, in step S5, after the cover plate is snap-fitted to the integral bracket, glue sealing is performed at the gap between the cover plate and the integral bracket, thereby improving the sealing inside the integral bracket and improving the protection effect on the nanocrystalline magnetic ring.

[0079] In a preferred embodiment, in step S6, the injection depth of silicone gel only needs to ensure the relative position fixing effect between the capacitor, the nanocrystalline magnetic ring and the integral body. If too much silicone gel is injected, the cost will be high on the one hand, and the weight of the filter will increase on the other hand, which is not conducive to application in some scenarios.

[0080] like Figures 9 to 13 As shown, the embodiment of the present application also provides an injection mold for a filter, including an injection head 330 and a base mold 310 and a pressure mold 320 that can be pressed together. When the base mold 310 and the pressure mold 320 are pressed together, a sealed injection cavity is formed, and the injection head 330 can inject glue into the injection cavity.

[0081] Among them, the inner wall of the injection cavity is provided with a first isolating member 314 fixedly connected to the bottom mold 310, a second isolating member 322 fixedly connected to the pressure mold 320, and a positioning assembly for positioning the copper busbar 220 and the grounding member 280. When the bottom mold 310 and the pressure mold 320 are pressed together, the first isolating member 314 and the second isolating member 322 are interlocked and formed into an independent cavity for accommodating the nanocrystalline magnetic ring 240. A closed groove 315 that matches the gap with the copper busbar 220 is provided on the inner wall of the independent cavity.

[0082] In an embodiment of the present application, an injection mold as described above is used, the copper busbar 220 and the grounding piece 280 are positioned by a positioning assembly, and during the injection molding process, a first isolation piece 314 and a second isolation piece 322 are snapped together to form an independent cavity for accommodating the nanocrystalline magnetic ring 240. On the one hand, the integrated bracket 210 is injection molded on the copper busbar 220 and the grounding piece 280 in an integrated manner, and on the other hand, the nanocrystalline magnetic ring 240 can be protected to avoid the influence of the injection molding pressure on the nanocrystalline magnetic ring 240, thereby ensuring the overall quality of the finished filter product.

[0083] In a preferred embodiment, Figures 9 to 13 As shown, a first injection cavity 311 is provided on an end surface of the bottom mold 310 close to the pressing mold 320 , and a second injection cavity 321 is provided on an end surface of the pressing mold 320 close to the bottom mold 310 .

[0084] When the bottom mold 310 and the pressing mold 320 are pressed together, the first injection cavity 311 and the second injection cavity 321 cooperate to form an injection cavity that matches the shape of the integrated bracket 210 .

[0085] In a preferred embodiment, Figures 9 to 13 As shown, the first isolation member 314 is provided with a first isolation cavity 316 opening toward the compression mold 320 , and the second isolation member 322 is provided with a second isolation cavity 323 opening toward the bottom mold 310 .

[0086] When the bottom mold 310 and the pressing mold 320 are pressed together, the first isolation cavity 316 and the second isolation cavity 323 cooperate to form an independent cavity for accommodating the nanocrystalline magnetic ring 240 .

[0087] In a preferred embodiment, Figures 9 to 13 As shown, a closed groove 315 is formed on the inner wall of the first isolation cavity 316 to fit the gap of the copper busbar 220 .

[0088] It is understandable that the arrangement of the closed groove 315 is not limited to the above-mentioned one. For example, the closed groove 315 can also be arranged to be arranged through the inner wall of the second isolation cavity 323, or the closed groove 315 is arranged on the inner wall of the first isolation cavity 316 and the second isolation cavity 323, and the combination of the two closed grooves 315 on the first isolation member 314 and the second isolation member 322 forms a space for making way for the copper busbar 220. As long as the copper busbar 220 can be made to make way, it will not be described in detail here.

[0089] In a preferred embodiment, Fig.10 , Fig.11 As shown, a locking frame 312 for positioning the copper busbar 220 and a positioning frame 313 for positioning the grounding member 280 are provided on the inner wall of the first injection cavity 311 .

[0090] The copper busbar 220 can be embedded in the locking frame 312 , and the positioning frame 313 has guide posts respectively embedded with the first guide head and the second guide head of the grounding member 280 .

[0091] In a preferred embodiment, Fig.12 , Fig.13 As shown, a locking groove 325 for positioning the copper busbar 220 and a positioning embedding groove 324 for positioning the grounding piece 280 are provided on the inner wall of the second injection cavity 321 .

[0092] The copper busbar 220 can be embedded in the locking groove 325 , and the positioning embedding groove 324 can be engaged with the first guide head and the second guide head of the grounding member 280 .

[0093] like Figures 1 to 5 As shown, the embodiment of the present application also provides a push-pull test tool, including a base 110, a column 120 fixedly disposed on the base 110, a push-pull execution component 150 that can be raised and lowered on the column 120, and an installation and adjustment component disposed on the base 110.

[0094] The installation adjustment component includes a first adjustment plate 130, a second adjustment plate 140 slidably arranged on the end surface of the first adjustment plate 130 close to the push-pull actuator 150, a positioning column 111 is fixedly provided on the end surface of the base 110 close to the push-pull actuator 150, and a positioning groove 131 is provided on the first adjustment plate 130. The positioning column 111 is slidably arranged in the positioning groove 131 and the first adjustment plate 130 can rotate about the central axis of the positioning column 111.

[0095] The second adjustment plate 140 is provided with a plurality of installation slots 141 in a linear array and extending therethrough. Installation bolts 142 can be slidably arranged in the installation slots 141 . The installation bolts 142 can pass through the installation slots 141 from the side of the second adjustment plate 140 close to the base 110 and be threadedly connected to the workpiece to be tested.

[0096] The installation adjustment assembly further includes a first locking portion for limiting the relative position between the first adjustment plate 130 and the positioning column 111 and a second locking portion for limiting the relative position between the first adjustment plate 130 and the second adjustment plate 140 .

[0097] It is understandable that when performing push-pull force detection on a workpiece, its own posture state during detection may be different based on different workpiece shapes and specifications, so it is necessary to move it to the test area of ​​the push-pull execution component 150 while satisfying the workpiece detection posture.

[0098] In an embodiment of the present application, the above-mentioned push-pull test fixture is adopted, the first adjustment plate 130 can slide and rotate linearly relative to the positioning column 111, and the second adjustment plate 140 can slide linearly relative to the first adjustment plate 130. When the workpiece to be tested is fixedly connected to the second adjustment plate 140 by the mounting bolts 142, the workpiece to be tested can be moved to the working area of ​​the push-pull execution component 150 by adjusting the relative position between the second adjustment plate 140 and the first adjustment plate 130 and between the first adjustment plate 130 and the positioning column 111. The workpiece transfer range is large and the detection posture applicability is strong. After the relative position between the positioning column 111, the first adjustment plate 130 and the second adjustment plate 140 is limited by the first locking portion and the second locking portion, the test work on the workpiece to be tested can be performed by the push-pull execution component 150, and at the same time, the position stability of the workpiece to be tested during the push-pull test is ensured.

[0099] On the other hand, the workpiece to be tested is fixedly connected to the second adjustment plate 140 by means of mounting bolts 142. Based on the different specifications of the workpiece to be tested, the mounting bolts 142 can be selected to pass through mounting slots 141 in different orientations to match the connection position of the workpiece to be tested. The structure is simple, which further improves the adaptability of the workpiece to be tested and reduces the push-pull force test cost of the workpiece.

[0100] In a preferred embodiment, Figure 5 As shown, the first locking portion includes a positioning nut 112 threadedly connected to the positioning column 111 . The positioning nut 112 is located at a side of the first adjustment plate 130 away from the base 110 and can contact the first adjustment plate 130 .

[0101] It is understandable that when the positioning nut 112 is not tightened, the first adjustment plate 130 can translate or rotate relative to the positioning column 111. When the positioning nut 112 is tightened, the relative displacement limitation between the first adjustment plate 130 and the positioning column 111 is achieved by the friction force between the positioning nut 112 and the first adjustment plate 130.

[0102] In a preferred embodiment, Figure 5 As shown, a stop groove 134 communicating with the positioning slide groove 131 is provided on the end surface of the first adjustment plate 130 away from the base 110 , and the positioning nut 112 can contact the inner wall of the stop groove 134 close to the base 110 .

[0103] In a preferred embodiment, the first locking portion further includes a first friction washer which is sleeved on the positioning column 111 and located between the positioning nut 112 and the inner wall of the abutting groove 134 on the side close to the base 110 .

[0104] It is understandable that when the positioning nut 112 is tightened, the friction between the positioning nut 112 and the first adjustment plate 130 can be increased by the first friction gasket, thereby improving the limiting effect on the relative movement between the first adjustment plate 130 and the positioning column 111.

[0105] In a preferred embodiment, Figures 2 to 4 As shown, two parallel translation grooves 143 are provided on the second adjustment plate 140, and the second locking portion includes a limiting bolt 133 slidably arranged in the translation groove 143. The limiting bolt 133 passes through the translation groove 143 from the side of the second adjustment plate 140 away from the first adjustment plate 130 and is threadedly connected to the first adjustment plate 130.

[0106] The bolt head of the limiting bolt 133 can contact the second adjustment plate 140 to limit the relative displacement between the second adjustment plate 140 and the first adjustment plate 130 .

[0107] It can be understood that when the limit bolt 133 is not tightened, under the cooperation of the sliding guide of the limit bolt 133 and the translation groove 143, the second adjustment plate 140 can translate relative to the first adjustment plate 130 along the length direction of the translation groove 143. When the limit bolt 133 is tightened, the relative displacement limitation between the second adjustment plate 140 and the first adjustment plate 130 is achieved by the friction force between the bolt head of the limit bolt 133 and the second adjustment plate 140.

[0108] In a preferred embodiment, Figures 1 to 4 As shown, the length direction of the translation sliding groove 143 is perpendicular to the length direction of the positioning sliding groove 131 .

[0109] It can be understood that by vertically setting the translation slot 143 and the positioning slot 131, the workpiece to be tested can be transferred to any position on the horizontal plane (within the moving range of the first adjustment plate 130 and the second adjustment plate 140), ensuring the adaptation to different test posture requirements of the workpiece to be tested.

[0110] In a preferred embodiment, Figure 3 , Figure 4 As shown, a locking slot 145 communicating with the translation slot 143 is provided on the end surface of the second adjustment plate 140 away from the base 110 , and the bolt head of the limiting bolt 133 can abut against the inner wall of the locking slot 145 close to the base 110 .

[0111] In a preferred embodiment, the second locking portion further includes a second friction washer which is sleeved on the limiting bolt 133 and is located between the bolt head of the limiting bolt 133 and the inner wall of the locking slot 145 on the side close to the base 110 .

[0112] It is understandable that when the limiting bolt 133 is tightened, the friction between the limiting bolt 133 and the second adjustment plate 140 can be increased by the second friction gasket, thereby improving the limiting effect on the relative movement between the first adjustment plate 130 and the second adjustment plate 140 .

[0113] In a preferred embodiment, Figure 4 , Figure 5 As shown, a plurality of positioning holes 132 capable of being threadedly connected with the limiting bolts 133 are provided on the first adjustment plate 130 along the length direction of the translational slide slot 143 .

[0114] It can be understood that by arranging multiple positioning holes 132 in the length direction of the translation slide groove 143, the relative position of the limit bolt 133 on the first adjustment plate 130 can be adjusted, thereby providing the second adjustment plate 140 with a larger moving stroke range relative to the first adjustment plate 130, thereby further improving its applicability to the specifications of the workpiece to be tested while ensuring the volume of the installed adjustment component.

[0115] In a preferred embodiment, Figure 3 As shown, a clearance groove 144 communicating with the mounting groove 141 is provided on the end surface of the second adjustment plate 140 close to the base 110 , and the bolt head of the mounting bolt 142 can abut against the inner wall of the clearance groove 144 away from the base 110 .

[0116] It is understandable that when the mounting bolt 142 is tightened, the relative position of the mounting bolt 142 and the second adjustment plate 140 is fixed by the friction force between the bolt head of the mounting bolt 142 and the second adjustment plate 140, thereby fixing the relative position of the workpiece to be tested and the second adjustment plate 140.

[0117] In a preferred embodiment, a third friction pad is sleeved on the mounting bolt 142 and is located between the bolt head of the mounting bolt 142 and the inner wall of the clearance groove 144 away from the base 110 .

[0118] It can be understood that when the mounting bolt 142 is tightened, the friction between the mounting bolt 142 and the second adjustment plate 140 can be increased through the third friction gasket, thereby improving the limiting effect of the relative movement between the mounting bolt 142 and the second adjustment plate 140, thereby ensuring the installation stability of the workpiece to be tested and avoiding position displacement during the push-pull force test.

[0119] In a preferred embodiment, Figure 1 , Figure 2 As shown, the workpiece to be tested is specifically a filter 200 , and a mounting hole threadedly connected to the mounting bolt 142 is provided through the filter 200 .
