Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of capacitors, and in particular to a grounding structure and a capacitor. Background Art

[0002] Capacitors are a common electronic component and an integral part of circuits. In order to improve the filtering effect of capacitors and the quality of circuits, it is often necessary to ground one end of the capacitor in the circuit. Specifically, the capacitor grounding effect is achieved by forming an effective connection between the capacitor and the grounding wire.

[0003] However, when the existing capacitor is connected to the grounding wire, it is difficult for the capacitor to adapt to the complex and changeable grounding wire installation conditions and has poor applicability. Utility Model Content

[0004] The present application provides a capacitor, which can make the capacitor have better applicability.

[0005] In a first aspect, the present application provides a grounding structure, which is applied to a capacitor, wherein the capacitor includes a capacitor body, and the grounding structure includes an adjustment component and a grounding column arranged on the capacitor body. A positioning groove is provided on the grounding column, and a connecting hole is provided on the groove wall of the positioning groove, and the connecting hole is connected to the positioning groove, and the positioning groove is used to place a grounding wire. The adjustment component includes a fastener and an adjustment member, wherein the first end of the fastener passes through the connecting hole, the adjustment member is rotatably connected to the first end and is located in the positioning groove, and the adjustment member is used to clamp the grounding wire.

[0006] The setting form in which the adjusting member is rotatably connected to the first end of the fastener enables the adjusting member to clamp the grounding wires at different setting angles by rotating to different positions. By rotating the fastener, the adjusting member connected to the fastener applies a squeezing force to the grounding wire to prevent the grounding wire from being separated from the positioning groove, so that the grounding structure and the grounding wires at different connection positions maintain a good connection strength, so that the grounding structure can adapt to complex and changeable grounding wire installation conditions and has good applicability.

[0007] In a possible design, the adjusting member is riveted to the first end so that the adjusting member is rotatably connected to the first end.

[0008] Through the above scheme, the riveting connection method can not only form a stronger connection strength between the adjusting member and the first end of the fastener, but also enable the adjusting member to be rotated at different angles at will, so that the adjusting member can clamp the grounding wire with different setting angles, thereby making the wiring structure have better applicability.

[0009] In a possible design, a clamping portion is provided on a side of the adjusting member facing away from the connecting hole, and the clamping portion is used to clamp and fix the grounding wire.

[0010] Through the above scheme, the grounding wire is clamped and fixed between the clamping portion and the side wall of the positioning groove without a connecting hole, thereby improving the clamping and fixing effect of the grounding structure on the grounding wire.

[0011] In a possible design, the clamping portion is configured as a clamping slot provided on the adjusting member, and the grounding wire is clamped in the clamping slot. And / or, the clamping portion is configured as at least two clamping blocks provided on the adjusting member, and the grounding wire is clamped between the two clamping blocks.

[0012] Through the above scheme, this setting method can increase the contact area between the grounding structure and the grounding wire, thereby increasing the friction between the grounding structure and the grounding wire, avoiding the grounding wire from slipping in the grounding structure, and further improving the clamping and fixing effect of the grounding structure on the grounding wire.

[0013] In a possible design, the holding portion is a card slot, and when there are multiple card slots, the multiple card slots are arranged at intervals; when the holding portion is a card block, at least two card blocks are arranged at intervals.

[0014] Through the above solution, this setting method allows the user to select a suitable clamping and fixing position according to needs, so that the grounding structure can adapt to complex and changeable grounding wire installation conditions and has better applicability.

[0015] In a possible design, a plurality of anti-slip grooves and / or anti-slip convex strips are arranged on the groove wall of the positioning groove away from the connecting hole.

[0016] Through the above scheme, this setting form can improve the surface roughness of the groove wall area to increase the friction between the groove wall area and the grounding wire, prevent the grounding wire from moving in the direction toward the notch of the positioning groove after being clamped and fixed, and prevent the grounding wire from escaping from the positioning groove.

[0017] In one possible design, the ground post is screw-riveted to the capacitor body.

[0018] Through the above solution, compared with conventional welding, rotary riveting can avoid thermal deformation and maintain better connection strength between the grounding column and the capacitor body.

[0019] In a second aspect, the present application provides a capacitor, comprising a capacitor body and the grounding structure in the first aspect, wherein the grounding structure is arranged on the capacitor body.

[0020] The capacitor has the same structure and beneficial effects as the grounding structure in the above embodiment. The structure and beneficial effects of the grounding structure have been described in detail in the above embodiment and will not be repeated here.

[0021] In a possible design, the capacitor body includes a cover plate, and the grounding column is riveted to the cover plate.

[0022] Through the above solution, usually, the existing grounding column and cover plate are mostly connected by soldering, which is affected by the welding quality and is prone to poor bonding strength. In addition, since the capacitor generates a lot of heat during operation, the working environment temperature is high, and the melting point of metal tin is low, the solder joints are easily deformed or even fall off due to the high ambient temperature. The rotary riveting can overcome the above problems and maintain good connection strength between the grounding column and the cover plate.

[0023] In a possible design, a grounding mark is provided in an area of ​​the cover plate close to the grounding post.

[0024] Through the above solution, the grounding mark makes it easy for operators to quickly identify and obtain the functional purpose of the grounding post.

[0025] The beneficial effects of the capacitor provided in the second aspect and each possible design of the second aspect can be referred to the beneficial effects brought about by the first aspect and each possible implementation method of the first aspect, which will not be repeated here.

[0043] Figure 1 The overall structure diagram of a grounding structure provided in an embodiment of the present application is as follows: Figure 2 An exploded schematic diagram of a grounding structure provided in an embodiment of the present application, Figure 3This is a schematic diagram of the overall structure of a grounding column provided in an embodiment of the present application. Figures 1 to 3 As shown, the present application provides a grounding structure 100 applied to a capacitor, wherein the capacitor includes a capacitor body, and the grounding structure 100 includes an adjustment component 110 and a grounding column 120 disposed on the capacitor body.

[0044] The grounding column 120 is provided with a positioning groove 121, and the groove wall of the positioning groove 121 is provided with a connecting hole 122, the connecting hole 122 is connected to the positioning groove 121, and the positioning groove 121 is used to place the grounding wire. The adjustment component 110 includes a fastener 111 and an adjustment member 112, the first end 1111 of the fastener 111 passes through the connecting hole 122, the adjustment member 112 is rotatably connected to the first end 1111 and is located in the positioning groove 121, and the adjustment member 112 is used to clamp the grounding wire.

[0045] It should be noted that "complex and changeable grounding wire installation conditions" mainly refers to the grounding wire not only being set horizontally when clamped and fixed, but also being set at a certain angle to the horizontal plane when clamped and fixed. Conventional capacitors can clamp and fix horizontally set grounding wires and form a good connection strength between the capacitor and the grounding wire, but conventional capacitors are difficult to clamp and fix horizontal planes to form a grounding wire set at a certain angle.

[0046] The capacitor body is the core structure of the capacitor, which can be used to store charge and generate electric field.

[0047] The grounding post 120 may be substantially cylindrical or prism-shaped. Figure 1 and Figure 2 The grounding column 120 shown is cylindrical, but does not limit the shape of the grounding column 120. The grounding column 120 can be connected to the capacitor body by riveting, welding, gluing, etc., and a suitable connection method can be selected according to actual needs.

[0048] The positioning groove 121 is arranged at one end of the grounding column 120 away from the capacitor body. The positioning groove 121 penetrates the grounding column 120 along the first direction, and the side of the positioning groove 121 facing away from the capacitor body is open, and the positioning groove 121 includes two groove walls with opposite positions along the second direction. Among them, the first direction is consistent with the extension direction of the grounding wire. The second direction is roughly perpendicular to the first direction, and roughly perpendicular to the arrangement direction of the grounding column 120 and the capacitor body. Roughly vertical means basically vertical. In addition to vertical in a strict sense, two directions with an angle of 85 degrees, 89 degrees, etc. close to 90 degrees should fall within the protection scope of the present application being roughly perpendicular.

[0049] The preset part of the grounding wire is placed in the positioning groove 121. The preset part is a part of the grounding wire except the end of the grounding wire. The preset part of the grounding wire can be placed in the positioning groove 121 from the opening of the side of the positioning groove 121 facing away from the capacitor body, or one end of the grounding wire can pass through the positioning groove 121 along the first direction to realize the placement of the grounding wire in the positioning groove 121.

[0050] The connecting hole 122 is arranged on any one of the two groove walls of the aforementioned positioning groove 121 along the second direction, and the connecting hole 122 passes through the groove wall where the connecting hole 122 is located to be connected with the positioning groove 121, so that the first end of the fastener 111 can pass through the connecting hole from the side of the groove wall facing away from the positioning groove 121 and extend into the positioning groove 121.

[0051] The connection hole 122 may be a round hole or a square hole, etc. The shape of the connection hole 122 may be set according to the shape of the fastener 111, and the size of the connection hole 122 may be set according to the thickness of the fastener 111, as long as the connection hole 122 can allow the first end 1111 of the fastener 111 to pass through. The connection hole 122 may be a threaded hole, or a bare hole with no thread on the hole wall, which is not limited in the present embodiment.

[0052] The fastener 111 may be a screw, a bolt, a pin, etc. The adjusting member 112 may be a plate-like structure, and the side of the adjusting member 112 facing away from the connecting hole 122 may be circular or square.

[0053] In actual production applications, the fastener 111, the adjustment member 112 and the grounding column 120 can be made of metal. Metal has good machinability, strength and conductivity, which facilitates the processing and production of the grounding structure 100, so that the grounding structure 100 has a certain structural strength, and is conducive to forming an electrical connection between the grounding wire and the grounding structure 100 to achieve grounding.

[0054] The adjusting member 112 can also be made by a metal dipping process, which not only retains the advantages of metal materials, but also can use the coated dipping layer to protect the grounding wire, thereby preventing the metal adjusting member 112 from damaging the grounding wire due to accidental situations such as scratches during the operation of clamping and fixing the grounding wire.

[0055] The adjusting member 112 is rotatably connected to the first end 1111 of the fastener 111, so that the adjusting member 112 can clamp the grounding wires at different setting angles by rotating to different positions. By rotating the fastener 111, the adjusting member 112 connected to the fastener 111 applies a squeezing force to the grounding wire to prevent the grounding wire from being separated from the positioning groove 121, so that the grounding structure 100 maintains a good connection strength with the grounding wires at different connection positions, so that the grounding structure 100 can adapt to complex and changeable grounding wire installation conditions and has good applicability.

[0056] The adjusting member 112 is connected to the first end 1111 of the fastener 111, so that the area of ​​the side of the adjusting member 112 facing the grounding wire is set larger than the area of ​​the side of the first end 1111 facing the grounding wire. In this way, the contact area between the adjusting member 112 and the grounding wire is larger than the contact area between the first end 1111 and the grounding wire, so the adjusting member 112 can increase the contact area between the grounding wire and the grounding structure 100, thereby facilitating the increase of the friction between the grounding wire and the grounding structure 100, so that the grounding structure 100 can clamp and fix the grounding wire more stably.

[0057] In an optional embodiment, the connection hole 122 may be a threaded hole, the fastener 111 may be a bolt, and the fastener 111 and the connection hole 122 may be matched with each other by a threaded connection.

[0058] By rotating the fastener 111, the first end 1111 of the fastener 111 and the adjusting member 112 are moved close to or away from the side wall of the positioning groove 121 where the connecting hole 122 is not provided, so as to adjust the distance between the adjusting member 112 and the above-mentioned side wall as needed, so that the grounding structure 100 can quickly install and remove the grounding wire, and the grounding structure 100 can be suitable for grounding wires of different diameters.

[0059] In addition, after the fastener 111 is rotated until the adjusting member 112 abuts against the grounding wire, the fastener 111 is further rotated so that the adjusting member 112 squeezes the grounding wire, thereby achieving a better position fixing effect on the grounding wire.

[0060] In another optional embodiment, the fastener 111 and the connecting hole 122 can be connected by interference fit, and the interference fit allows the outer wall of the fastener 111 and the inner wall of the connecting hole 122 to form a stronger connection strength between the fastener 111 and the connecting hole 122.

[0061] Specifically, the depth of the positioning groove 121 can be greater than the radial diameter of the grounding wire, so that the grounding wire can be completely placed in the positioning groove 121, and cooperate with the adjustment member 112 to clamp and fix the grounding wire to prevent the grounding wire from detaching from the positioning groove 121, so as to maintain better connection strength between the grounding structure 100 and the grounding wire.

[0062] It should be noted that the positioning groove 121 is located at the end of the grounding column 120 away from the capacitor body, and the notch of the positioning groove 121 is a straight opening. This arrangement not only facilitates the placement of the grounding wire into the positioning groove 121, but also enables the positioning groove 121 to limit the grounding wire. The positioning groove 121 has only one side of the groove wall provided with a connecting hole 122, and the "first end 1111 of the fastener 111" refers to the end of the groove wall facing the other side of the positioning groove 121 after the fastener 111 is inserted into the connecting hole 122.

[0063] In an optional embodiment, the ground wire can be a bare copper wire. Compared with conventional wires with protective sheaths, bare copper wire has the following advantages: 1. The processing technology is relatively simple and the production cost is low; 2. Under the same conductive cross-sectional area, the amount of bare copper wire required is less; 3. There is no need to remove the protective sheath during construction, reducing labor intensity and workload; 4. Bare copper wire has good heat dissipation effect and is easy to carry large instantaneous short-circuit current.

[0064] Figure 4 A schematic diagram of the assembly structure of an adjusting member and a fastener provided in an embodiment of the present application, see Figure 2 and Figure 4 Through the grounding structure 100 provided in the first aspect, the adjusting member 112 is riveted to the first end 1111 so that the adjusting member 112 is rotatably connected to the first end 1111 .

[0065] The riveted connection method not only enables the adjusting member 112 to form a stronger connection strength with the first end 1111 of the fastener 111, but also enables the adjusting member 112 to be rotated at different angles at will, so that the adjusting member 112 can clamp the grounding wires at different setting angles, thereby making the wiring structure have better applicability.

[0066] In an optional embodiment, the riveting position of the adjusting member 112 and the first end 1111 can be approximately located at the geometric center of the adjusting member 112. Since the geometric center of an object is easy to measure and locate, this arrangement can facilitate the processing and positioning of the riveting position when the adjusting member 112 is riveted. On the other hand, when the adjusting member 112 is a regular-shaped object with uniform mass distribution, the geometric center of the adjusting member 112 is also the center of gravity of the adjusting member 112, so that the mass distribution around the rotation center of the adjusting member 112 is consistent, thereby making the rotation adjustment of the adjusting member 112 more convenient and reasonable.

[0067] Figure 5 A schematic diagram of the structure of an adjustment member provided in an embodiment of the present application at a first viewing angle. In a possible design, as Figure 5 As shown, a clamping portion 130 may be provided on a side of the adjustment member 112 facing away from the connection hole 122 , and the clamping portion 130 is used to clamp and fix the grounding wire.

[0068] In an optional embodiment, the holding portion 130 may be configured as a slot (not shown in the figure) provided on the adjusting member 112, and the ground wire is held in the slot.

[0069] The slot can be a U-shaped slot. The U-shaped slot makes the slot fit the grounding wire more closely, increases the contact area between the slot and the grounding wire, thereby increasing the friction between the slot and the grounding wire, preventing the grounding wire from slipping in the slot, and thus improving the clamping and fixing effect of the grounding structure 100 on the grounding wire.

[0070] In another optional embodiment, the clamping portion 130 can be configured as at least two clamping blocks provided on the adjusting member 112, and the grounding wire is clamped between the two clamping blocks. Specifically, the grounding wire is clamped between the opposite side walls of the two clamping blocks, and the side wall structure and the friction between the grounding wire and the side wall stabilize and fix the grounding wire.

[0071] In actual production applications, the cross-sectional shape of the card block can be a regular shape, such as a triangle, rectangle, etc., or an irregular shape. Under the premise of not affecting the clamping and fixing effect of the card block on the ground wire, the embodiment of the present application does not make specific restrictions on the cross-sectional shape of the card block. Among them, the cross-sectional shape of the card block refers to the cross-sectional shape formed by the contact surface between the card block and the adjusting member 112 as the bottom surface.

[0072] In another optional embodiment, the clamping portion 130 can be configured as a clamping slot and at least two clamping blocks provided on the adjusting member 112. Specifically, the two clamping blocks are respectively located on both sides of the clamping slot, so that the grounding wire is clamped in the clamping slot, and the grounding wire is clamped between the two clamping blocks. This arrangement increases the contact area between the grounding wire and the clamping portion 130, thereby strengthening the friction between the grounding wire and the clamping portion 130, and further strengthening the clamping and fixing effect of the grounding wire.

[0073] By cooperating between the clamping portion 130 and the side wall of the positioning slot 121 without the connecting hole 122 , the ground wire is clamped and fixed between the clamping portion 130 and the side wall of the positioning slot 121 , thereby improving the clamping and fixing effect of the grounding structure 100 on the ground wire.

[0074] When the holding portion 130 is a card slot, and there are multiple card slots, the multiple card slots can be arranged at intervals.

[0075] Specifically, the plurality of slots may be arranged in an array on the adjusting member 112 (i.e., the plurality of slots are arranged at equal intervals on the adjusting member 112), or may be arranged at unequal intervals on the adjusting member 112. This arrangement allows the user to select a suitable clamping and fixing position according to needs, so that the grounding structure 100 can adapt to complex and changeable grounding wire installation conditions, so as to have better applicability.

[0076] When the holding portion 130 is a block, at least two blocks may be arranged at intervals.

[0077] Specifically, when two card blocks form a group, and there are multiple groups of card blocks, the multiple groups of card blocks can be arranged at equal intervals or at unequal intervals. This arrangement allows the user to select a suitable clamping and fixing position according to needs, so that the grounding structure 100 can adapt to complex and changeable grounding wire installation conditions and has better applicability.

[0078] Figure 6 A schematic diagram of the structure of an adjustment member provided in an embodiment of the present application at a second viewing angle is shown in FIG. Figure 6 As shown, a weight-reducing groove 123 may be provided on the side of the adjusting member 112 facing away from the grounding wire. The clamping portion 130 and the adjusting member 112 are designed as an integrated molding, and the adjusting member 112 is made by stamping.

[0079] The process selection of stamping and forming the adjusting member 112 can simplify the processing steps of the adjusting member 112, avoid extra material waste, reduce the production and processing cost of the adjusting member 112, and make the production and processing of the adjusting member 112 green and environmentally friendly. In addition, the weight-reducing groove 123 can reduce the material usage of the adjusting member 112, reduce the weight of the adjusting member 112, and thus reduce the production and processing cost of the adjusting member 112.

[0080] In one possible design, see Figure 3 A plurality of anti-slip grooves 140 may be provided on the groove wall of the positioning groove 121 away from the connecting hole 122 .

[0081] Compared with the groove wall with a smooth surface, multiple anti-slip grooves 140 can increase the surface roughness of the groove wall. Since the grounding wire contacts the groove wall of the positioning groove 121 away from the connecting hole 122 when being clamped and fixed, the above-mentioned setting can increase the friction between the groove wall and the grounding wire to prevent the grounding wire from falling off the positioning groove 121.

[0082] Specifically, the plurality of anti-skid grooves 140 may be arranged in an array on the groove wall. This arrangement enables the area on the groove wall where the anti-skid grooves 140 are arranged to have the same surface roughness, thereby maintaining a stable friction force between the ground wire and the above area.

[0083] Multiple anti-slip grooves 140 can also be arranged at unequal intervals on the groove wall. In practical applications, the distribution density of the anti-slip grooves 140 can be increased near the commonly used setting position of the grounding wire, and the distribution density of the anti-slip grooves 140 at other positions on the groove wall can be reduced.

[0084] While ensuring that a strong friction force is maintained between the ground wire and the groove wall, the number of anti-slip grooves is appropriately reduced to reduce the processing difficulty of the groove wall of the positioning groove 121 and improve the processing efficiency.

[0085] In another optional embodiment, an anti-slip convex strip (not shown in the figure) may be provided on the groove wall of the positioning groove 121 away from the connecting hole 122 .

[0086] Compared with the smooth surface of the groove wall, the anti-slip convex strip can increase the surface roughness of the groove wall. Since the grounding wire is clamped and fixed with the groove wall of the positioning groove 121 away from the connecting hole 122, the above-mentioned setting can increase the friction between the groove wall and the grounding wire to prevent the grounding wire from falling off the positioning groove 121.

[0087] The number of anti-skid convex strips can be multiple, and multiple anti-skid convex strips can increase the surface roughness of the groove wall, so that the grounding wire is not easy to slide in the area where the anti-skid convex strips are set, so as to better fix the grounding wire. Specifically, the multiple anti-skid grooves 140 can be arranged in an array on the groove wall. This arrangement makes the area on the groove wall where the anti-skid grooves 140 are set have the same surface roughness, so that the grounding wire maintains a stable friction force with the above area.

[0088] In another optional embodiment, the groove wall of the positioning groove 121 away from the connecting hole 122 may be provided with anti-slip convex strips and anti-slip grooves 140 at the same time.

[0089] Specifically, the anti-slip ridges and the anti-slip grooves 140 are arranged at intervals. This arrangement can improve the surface roughness of the groove wall area to increase the friction between the groove wall area and the grounding wire, thereby preventing the grounding wire from moving in the direction toward the groove opening of the positioning groove 121 after being clamped and fixed, thereby preventing the grounding wire from detaching from the positioning groove 121.

[0090] Through the grounding structure 100 provided in this embodiment, the grounding column 120 is riveted to the capacitor body. Compared with conventional welding, riveting can avoid thermal deformation and maintain better connection strength between the grounding column 120 and the capacitor body.

[0091] In an alternative embodiment, the grounding post 120 may be screwed to the capacitor body.

[0092] See also Figure 3 , a riveting portion 123 may be provided at one end of the grounding column 120 facing the capacitor body, and the grounding column 120 is riveted to the capacitor body through the riveting portion 123. Specifically, the riveting process of the riveting portion 123 may be circumferential riveting or radial riveting, preferably radial riveting. Compared with traditional circumferential riveting, radial riveting requires lower riveting force, and the friction and noise generated during the riveting process are also smaller. In addition, the shape of the riveting portion may be cylindrical or non-cylindrical, such as a prism.

[0093] Figure 7 A schematic diagram of the overall structure of a capacitor provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, the present application provides a capacitor 200 , including a capacitor body 210 and the above-mentioned grounding structure 100 , wherein the grounding structure 100 is disposed on the capacitor body 210 .

[0094] The capacitor 200 has the same structure and benefits as the grounding structure 100 in the above embodiment. The structure and benefits of the grounding structure 100 have been described in detail in the above embodiment and will not be repeated here.

[0095] Specifically, the grounding structure 100 is connected to the capacitor body 210 via the grounding column 120 , wherein the grounding column 120 is rotatably connected to the capacitor body 210 .

[0096] Figure 8 A schematic diagram of an assembly structure of multiple capacitors and ground wires provided in an embodiment of the present application. In actual production applications, Figure 8 As shown, the grounding wire 300 and multiple capacitors 200 can be electrically connected to the ground through the grounding wire 300 at the same time. On the one hand, it is convenient to manage multiple capacitors 200 after they are connected into groups. On the other hand, after multiple capacitors 200 are connected, they can have a better filtering effect and improve the working quality of the capacitors 200.

[0097] In one possible design, see Figure 7 The capacitor body 210 includes a cover plate 211 , and the grounding column 120 is riveted to the cover plate 211 .

[0098] Generally, the existing grounding column 120 and the cover plate 211 are mostly connected by soldering, which is affected by the welding quality and is prone to poor bonding strength. In addition, since the capacitor 200 generates a lot of heat during operation, the working environment temperature is high, and the melting point of metal tin is low, the solder joints are easily deformed due to the high ambient temperature, which leads to a decrease in the connection strength of the solder joints. Riveting can overcome the above problems, so that the grounding column 120 and the cover plate 211 maintain good connection strength.

[0099] The grounding structure provided by this embodiment, see Figure 7 A grounding mark 220 may be provided in an area of ​​the cover plate 211 close to the grounding column 120 .

[0100] In practical applications, the grounding mark 220 may be a universal standard symbol, so that the grounding mark 220 is convenient for operators to quickly identify and obtain the functional purpose of the grounding post 120. The grounding mark 220 may also be other shapes and patterns, such as columnar protrusions, text marks, etc., and the grounding meaning of the corresponding shape and pattern needs to be explained in the product manual.
