Description

Technical Field

[0001] This application relates to the field of electrical installation auxiliary components, and in particular to a wire clamping plate and its electrical plate. Background Technology

[0002] In the field of electrical connections, wire clamps play a crucial role. With the widespread application of electrical equipment, the fixing and management of wires has become increasingly critical. In various electrical systems, whether complex industrial production lines or everyday household appliances, there are numerous wires. If these wires are not effectively secured, they are prone to loosening and displacement during equipment operation due to vibration, pulling, and other factors. This not only affects the normal operation of the equipment but may also cause serious safety hazards such as short circuits and leakage. Therefore, auxiliary components like wire clamps are needed to ensure the proper installation of wires.

[0003] However, existing pressure plates have many shortcomings. For example, the lack of positioning components between the upper and lower pressure plates leads to excessively long installation times. Current solutions include adding positioning components or fixing the upper and lower pressure plates to ensure more accurate installation. The former requires positioning components on the upper and lower pressure plates, which increases processing costs. The latter results in a large pressure plate that occupies too much space, affecting transportation and packaging. There is also the issue of matching mounting brackets. When designed separately, if a pressure plate is lost, the corresponding matching pressure plate needs to be found, causing many problems. Summary of the Invention

[0004] In order to overcome the shortcomings of existing pressure plates that lack low-cost positioning components, this application provides a pressure plate and its electrical board, which can achieve low-cost and accurate installation and positioning of the pressure plate.

[0005] To achieve the above objectives, this application adopts the following technical solution: a pressure plate, including a first pressure plate and a second pressure plate. The top surface of the first pressure plate has a first through groove with an upward opening that connects the front and rear sides. The bottom surface of the second pressure plate has a second through groove with a downward opening that is symmetrical to the first through groove. The top surface of the first pressure plate is provided with a first positioning part, and the bottom surface of the second pressure plate is provided with a second positioning part that is adapted to the first positioning part. After the first positioning part and the second positioning part cooperate, the first through groove and the second through groove form a through hole. The first positioning part and the second positioning part are symmetrical about the midpoint of the mating surface, and are also symmetrical about the midpoint of the mating surface.

[0006] After adopting the above technical solution, this application has the following advantages: Since the first and second through slots are symmetrical vertically, and the first and second positioning parts are symmetrical about the midpoint of the mating surface, and are also symmetrical about that point, the first and second pressure plates can be made into two identical pressure plates. They can be combined simply by changing their direction, and can form corresponding through holes for pressing wires of the corresponding size. This design allows for the manufacture of only one type of pressure plate to form a complete pressure plate. Even if one pressure plate, such as the upper or lower pressure plate, is lost during installation, it will not affect the installer's ability to use two identical pressure plates to form a complete pressure plate, reducing usage and design costs. Furthermore, the symmetrical positioning parts of the upper and lower pressure plates (requiring no additional parts) reduce processing costs while achieving the installation positioning function. Compared to the traditional solution of adding independent positioning components, and since the first and second pressure plates can be installed separately, packaging and transportation costs are also reduced.

[0007] Furthermore, the first and second through slots have various sizes so that when combined, they can form through holes of various sizes.

[0008] Using the aforementioned technical solution, in actual electrical connection scenarios, wires of different specifications require corresponding through-hole sizes on the wire clamping plate. The first and second through slots are available in various sizes, allowing for the combination of through-holes of various sizes. This enables the wire clamping plate to accommodate wires of different diameters or thicknesses. Whether for thick cables on industrial production lines or thin wires in household appliances, suitable through-hole sizes can be found for fixing, greatly improving the versatility and applicability of the wire clamping plate in different electrical devices.

[0009] Furthermore, the plurality of through holes include three circular holes and one oblong hole, and are offset in the left-right direction.

[0010] By adopting the aforementioned technical solution, since the wiring groove and the mounting hole on the electrical board in the prior art are asymmetrically designed, setting the through hole as an offset layout can adapt to the position of the wiring groove on the electrical board, increase adaptability, and after rotating 180°, another set of holes can be used to connect with the wiring groove of the electrical board.

[0011] Furthermore, the first pressure plate and the second pressure plate are provided with a first mounting hole penetrating their upper and lower surfaces.

[0012] Using the aforementioned technical solution, the first and second pressure plates can be securely fixed together using bolts, screws, or other fasteners through multiple pairs of through-holes on both the top and bottom surfaces. This design ensures that the pressure plate can stably secure the wires after installation, preventing loosening or displacement due to vibration, pulling, or other factors, thereby improving the reliability and safety of the electrical connection. Furthermore, the pressure plate can be directly mounted on the electrical board through the first mounting holes, providing a simple and effective fixing method.

[0013] Furthermore, the first mounting hole is designed to avoid through holes.

[0014] By employing the aforementioned technical solution, the design of the first mounting hole avoiding the through hole ensures that the position of the mounting hole will not interfere with the wires in the through hole. This design avoids wire compression or damage caused by the mounting hole overlapping with the wires during installation, thereby protecting the integrity of the wires and the reliability of the electrical connection.

[0015] Furthermore, the first pressure plate and the second pressure plate are provided with a second mounting hole penetrating through their upper and lower surfaces, and the second mounting hole is offset in the left and right direction.

[0016] Using the aforementioned technical solution, the wiring channels or mounting holes in electrical boards are typically designed asymmetrically. By setting the second mounting hole in an offset layout, this asymmetrical installation environment can be better adapted, ensuring that the wire clamp can accurately align with the mounting holes on the electrical board, thus improving compatibility and installation efficiency.

[0017] Furthermore, both the first positioning part and the second positioning part include a combination of protrusions and grooves.

[0018] By employing the aforementioned technical solution, the mating design of the protrusion and groove enables precise positioning between the first and second pressure plates. After the protrusion is embedded in the groove, it effectively restricts the relative movement of the pressure plates, ensuring alignment of the first and second through slots, thereby forming a complete through hole. This design improves the accuracy and efficiency of installation.

[0019] Furthermore, the boss and groove are tapered on the front and rear projection surfaces.

[0020] Using the aforementioned technical solution, the tapered boss and groove design make alignment easier during installation, allowing installers to quickly connect without precise adjustments. This design greatly simplifies the installation process, reduces installation difficulty, and improves work efficiency.

[0021] Furthermore, the first and second through grooves are provided with reinforcing ribs for pressing the wire.

[0022] By adopting the aforementioned technical solution, reinforcing ribs are set in the first and second through slots, so that the wire can be stably squeezed when installed in the through hole, making the wire more stable in the pressure plate and less likely to come out after installation, thus ensuring the stability and safety of the wire.

[0023] An electrical board includes an electrical board body and a wire clamping plate as described above. The electrical board body is provided with a wiring groove, and the wire clamping plate has two pairs of offset through holes. After the electrical board body and the wire clamping plate are installed, one pair of through holes corresponds to the wiring groove on the electrical board. After the wire clamping plate is rotated 180° with the vertical line in the vertical direction as the axis, it is installed with the electrical board body. The other pair of through holes corresponds to the wiring groove on the electrical board.

[0024] By adopting the aforementioned technical solution, since the existing wiring channels and mounting holes on electrical boards are mostly asymmetrically designed, the through holes of the pressure plate are set with an offset layout, including two pairs of offset through holes. This allows for better correspondence with the wiring channels on the electrical board, ensuring compatibility whether installed initially or after a 180° rotation. This significantly increases the compatibility between the pressure plate and the electrical board. The pressure plate can be installed by rotating 180° to the electrical board body, using different through holes to correspond with the wiring channels. This provides installers with more installation options, allowing for more flexible installation operations in different installation environments or with varying needs. Attached Figure Description

It should be understood that in this application, "multiple" refers to two or more. "And / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, X and / or Y can represent: X alone, X and Y simultaneously, and Y alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "Containing X, Y, and Z," "Containing X, Y, and Z" means that all three X, Y, and Z are included; "Containing X, Y, or Z" means that one of X, Y, and Z is included; "Containing X, Y, and / or Z" means that any one, two, or three of X, Y, and Z are included.

[0036] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0037] like Figures 1 to 7 As shown, this application provides a pressure plate, including a first pressure plate 1 and a second pressure plate 2. The top surface of the first pressure plate 1 has a first through groove 11 with an upward opening and connecting the front and rear sides. The bottom surface of the second pressure plate 2 has a second through groove 21 with a downward opening and symmetrical to the first through groove 11. The top surface of the first pressure plate 1 is provided with a first positioning part 12, and the bottom surface of the second pressure plate 2 is provided with a second positioning part 22 adapted to the first positioning part 12. After the first positioning part 12 and the second positioning part 22 are engaged, the first through groove 11 and the second through groove 21 form a through hole 3. The first positioning part 12 and the second positioning part 22 are symmetrical about the midpoint of the mating surface, and are also symmetrical about the midpoint of the mating surface.

[0038] After adopting the above technical solution, this application has the following advantages: Since the first through groove 11 and the second through groove 21 are symmetrical vertically, and the first positioning part 12 and the second positioning part 22 are symmetrical about the center point of the mating surface, and are also symmetrical about the center point of the mating surface, the first pressure plate 1 and the second pressure plate 2 can be made into two identical pressure plates. The combination of the two can be achieved simply by changing the direction, and they can form corresponding through holes 3 for pressing wires of corresponding sizes. This design allows for the manufacture of only one type of pressure plate to form a complete pressure plate. This means that if one pressure plate is lost during installation, such as the upper pressure plate or the lower pressure plate, it will not affect the installer's ability to use two identical pressure plates to form a complete pressure plate, reducing usage and design costs. Furthermore, the symmetrical positioning parts of the upper and lower pressure plates (without the need for additional parts) reduce processing costs while achieving the installation positioning function. Compared to the traditional solution of adding independent positioning components, and since the first pressure plate 1 and the second pressure plate 2 can be installed separately, packaging and transportation costs are also reduced.

[0039] Specifically, the midpoint of the bonding surface is the midpoint in the left-right and front-back directions on the upper and lower projection planes after the top surface of the first pressure plate 1 and the bottom surface of the second pressure plate 2 are bonded together. The first positioning part 12 and the second positioning part 22 are centrally symmetrical to each other, as indicated by a straight line extending left and right along the midpoint of the bonding surface. Figure 1 or Figure 2 The rotation axis shown in o1 is rotated 180° to form the shape; and the first positioning part 12 and the second positioning part 22 are themselves centrally symmetrical, formed by a straight line extending vertically along the midpoint of the mating surface, as shown in the figure. Figure 1 It is formed by rotating the rotation axis shown in o2 by 180°.

[0040] Furthermore, the first through groove 11 and the second through groove 21 have multiple sizes so that when they are combined, they form through holes 3 of multiple sizes.

[0041] Using the aforementioned technical solution, in actual electrical connection scenarios, wires of different specifications require corresponding through-hole sizes on the wire clamping plate. The first through-slot 11 and the second through-slot 21 have various sizes, which can be combined to create through-holes 3 of various sizes. This allows the wire clamping plate to accommodate wires of different diameters or thicknesses. Whether for thick cables on industrial production lines or thin wires in household appliances, suitable through-holes 3 can be found for fixing, greatly improving the versatility and applicability of the wire clamping plate in different electrical devices.

[0042] Furthermore, the through hole 3 includes three round holes and one oblong hole, and is offset in the left-right direction.

[0043] By adopting the aforementioned technical solution, since the wiring groove 8 and the mounting hole 9 on the electrical board in the prior art are asymmetrically designed, setting the through hole 3 to an offset layout can adapt to the position of the wiring groove 8 on the electrical board, increase adaptability, and after rotating 180°, another set of holes can be used to connect with the wiring groove 8 on the electrical board.

[0044] Specifically, the offset layout in the left and right directions means that, with the center symmetry plane of the left and right end faces of the pressure plate as the center of symmetry, the three round holes and one oblong hole are asymmetrical relative to this center of symmetry.

[0045] Furthermore, the first pressure plate 1 and the second pressure plate 2 are provided with a first mounting hole 4 that penetrates the upper and lower surfaces of both.

[0046] Using the aforementioned technical solution, the first pressure plate 1 and the second pressure plate 2 can be firmly fixed together using bolts, screws, or other fasteners through multiple pairs of through-holes 4. This design ensures that the pressure plate can stably fix the wires after installation, preventing loosening or displacement due to vibration, pulling, or other factors, thereby improving the reliability and safety of the electrical connection. Furthermore, the pressure plate can be directly mounted on the electrical board through the first mounting holes 4, providing a simple and effective fixing method.

[0047] Furthermore, the first mounting hole 4 is designed to avoid the through hole 3.

[0048] By employing the aforementioned technical solution, the design of the first mounting hole 4 avoiding the through hole 3 ensures that the position of the mounting hole will not interfere with the wire in the through hole 3. This design avoids wire squeezing or damage caused by the mounting hole overlapping with the wire during installation, thereby protecting the integrity of the wire and the reliability of the electrical connection.

[0049] Furthermore, the first pressure plate 1 and the second pressure plate 2 are provided with a second mounting hole 5 penetrating through their upper and lower surfaces, and the second mounting hole 5 is offset in the left and right direction.

[0050] Using the aforementioned technical solution, the wiring groove 8 or mounting holes in the electrical board are typically designed asymmetrically. By setting the second mounting hole 5 to an offset layout, this asymmetrical installation environment can be better adapted, ensuring that the wire clamp can accurately align with the mounting holes on the electrical board, thus improving compatibility and installation efficiency.

[0051] Specifically, the offset layout in the left and right directions means that, with the center symmetry plane of the left and right end faces of the pressure plate as the center of symmetry, the second mounting hole 5 is asymmetrical relative to this center of symmetry.

[0052] Furthermore, both the first positioning part 12 and the second positioning part 22 include a combination of protrusions and grooves.

[0053] By employing the aforementioned technical solution, the cooperative design of the protrusion and groove enables precise positioning between the first pressure plate 1 and the second pressure plate 2. After the protrusion is embedded in the groove, it effectively restricts the relative movement of the pressure plates, ensuring that the first through groove 11 and the second through groove 21 are aligned, thereby forming a complete through hole 3. This design improves the accuracy and efficiency of installation.

[0054] Specifically, the first positioning part 12 has alternating protrusions and grooves at the four corners of the top surface of the first pressure plate 1, and the second positioning part 22 has alternating protrusions and grooves at the four corners of the bottom surface of the second pressure plate 2.

[0055] It is understandable that the first positioning part and the second positioning part can also be other positioning methods, such as the positioning method of a snap fastener, etc., all of which are included in the protection scope of this technology.

[0056] Furthermore, the boss and groove are tapered on the front and rear projection surfaces.

[0057] Using the aforementioned technical solution, the tapered boss and groove design make alignment easier during installation, allowing installers to quickly connect without precise adjustments. This design greatly simplifies the installation process, reduces installation difficulty, and improves work efficiency.

[0058] Furthermore, the first through groove 11 and the second through groove 21 are provided with reinforcing ribs 6 for pressing the wire.

[0059] By adopting the aforementioned technical solution, reinforcing ribs 6 are provided in the first through groove 11 and the second through groove 21, so that the wire can be stably squeezed when it is installed in the through hole 3, making the wire more stable in the pressure plate and less likely to come out after installation, thus ensuring the stability and safety of the wire.

[0060] An electrical board includes an electrical board body 7 and a wire clamping plate as described above. The electrical board body 7 is provided with a wiring groove 8. The wire clamping plate has two pairs of through holes 3 with an offset arrangement. After the electrical board body 7 and the wire clamping plate are installed, one pair of through holes 3 corresponds to the wiring groove 8 on the electrical board. After the wire clamping plate is rotated 180° with the vertical line in the vertical direction as the axis, it is installed with the electrical board body 7. The other pair of through holes 3 corresponds to the wiring groove 8 on the electrical board.

[0061] By adopting the aforementioned technical solution, since the existing wiring grooves 8 and mounting holes 9 on the electrical board are mostly asymmetrically designed, the through holes 3 of the pressure plate are set in an offset layout, and include two pairs of offset through holes 3. This allows for better correspondence with the wiring grooves 8 on the electrical board. Whether installed initially or after rotating 180°, it can fit the wiring grooves 8 of the electrical board, greatly increasing the compatibility between the pressure plate and the electrical board. The pressure plate can be installed with the electrical board body 7 by rotating 180°, using different through holes 3 to correspond with the wiring grooves 8. This provides installers with more installation options, allowing for more flexible installation operations when facing different installation environments or needs.

[0062] Specifically, the electrical board in the prior art has four symmetrical mounting holes 9, but the wiring groove 8 is asymmetrically offset relative to the center of symmetry of the mounting holes 9. Therefore, when setting the position of the through hole 3, it needs to correspond to the wiring groove 8, and the first mounting hole 4 and the second mounting hole 5 need to correspond to the mounting holes 9 on the electrical board. As a result, the through hole 3 is in an offset position. In order to maximize the utilization of a single pressure plate, a single second mounting hole 5 is designed so that the mounting hole can be assembled with the corresponding mounting hole 9 whether it is installed initially or after rotating 180°. After the corresponding second mounting hole 5 avoids the through hole 3, the through hole 3 has two installation methods corresponding to the wiring groove 8.

[0063] In addition to the preferred embodiments described above, this application has other implementation methods. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection claimed in this application.
