Description

Technical Field

[0001] This utility model belongs to the field of terminal block technology, and in particular relates to a busbar terminal block. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. They allow for quick and stable connection between wires, thus enabling circuit continuity. Terminal blocks typically consist of a plastic housing, a conductive element housed within the housing, and a screw for securing the wires. Because tightening the screws requires drilling holes in the plastic housing, dust, insects, and other debris can easily enter the terminal block, affecting circuit stability. Furthermore, users can easily touch the screws, causing electric shock, posing a significant safety hazard.

[0003] In the existing technology, the dustproof effect of the terminal block is not good. In order to improve the dustproof effect and reduce safety hazards, the existing technology uses a dust cover to clip onto the outer shell. When using it, the dust cover needs to be removed. After wiring is completed, the clip needs to be aligned with the slot for installation. The installation and use are inconvenient, and the dust cover is easy to fall off and be lost. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a busbar terminal block. By rotatably mounting a rotating protrusion within a hinge hole, one end of the dust cover is hinged to the outer casing. A snap-fit ​​is then attached to the snap-fit ​​protrusion, allowing the other end of the dust cover to be snapped onto the outer casing. This facilitates opening and closing the dust cover, making operation simple and quick. Furthermore, the dust cover is less prone to falling off or being lost. The positioning and guiding function of the groove around the mounting opening, along with the cooperation between the first and second inclined surfaces, facilitates the installation of the dust cover.

[0005] In view of this, the present invention provides a busbar terminal block, comprising:

[0006] The outer casing has a mounting port on one side along the Z-axis, and first wiring holes are provided on both sides along the X-axis.

[0007] A conductor is disposed within the outer casing. Multiple first threaded holes are formed on the conductor along the Z-axis direction. A first wiring groove is also formed on the conductor, which is directly opposite to the first wiring hole. The first threaded hole is connected to the first wiring groove.

[0008] Multiple fastening screws are threaded onto the first threaded hole;

[0009] A cover plate is provided on the mounting opening. The cover plate has multiple first through holes, which are directly opposite to the first threaded holes. A receiving groove is formed between the cover plate and the mounting opening.

[0010] A dust cover is installed in the receiving groove, and reinforcing ribs are provided on the inner periphery of the dust cover;

[0011] The dust cover has two symmetrically arranged rotating protrusions on one end along the X-axis, and a buckle on the other end along the X-axis. The outer shell has two symmetrically arranged hinge holes near the mounting opening, and a snap-fit ​​protrusion adapted to the buckle is also provided on the outer shell. The rotating protrusion is rotatably disposed in the hinge hole, and the buckle snaps onto the snap-fit ​​protrusion. A groove is provided on the periphery of the mounting opening near the hinge hole, and a first inclined surface is provided on the groove. A second inclined surface adapted to the first inclined surface is provided on the rotating protrusion.

[0012] In the above scheme, two heat dissipation grooves are further provided on both sides of the outer shell in the Y-axis direction.

[0013] In the above scheme, a cable support platform is further provided on the outer casing at the first wiring hole.

[0014] In the above scheme, the dust cover is further provided with a label slot, and multiple indicator labels are snapped into the label slot.

[0015] In the above scheme, the cover plate is further provided with a second through hole, and the conductor is also provided with a second threaded hole directly opposite the second through hole. A fastening screw is also provided on the second threaded hole, and a second wiring groove is also provided on the conductor, with the second threaded hole connected to the second wiring groove.

[0016] In the above solution, the second wiring groove is further provided with anti-slip ridges, which are directly opposite the fastening screw.

[0017] In the above scheme, furthermore, a limiting protrusion is provided on the periphery of both the first through hole and the second through hole, and the inner diameter R1 of the limiting protrusion is smaller than the diameter R2 of the fastening screw.

[0018] In the above scheme, there are two snap-fit ​​protrusions, which are respectively set on both sides of the outer shell in the X-axis direction. There are four hinge holes, which are symmetrically set on both sides of the outer shell in the Y-axis direction. The periphery of the mounting opening is provided with four grooves that are close to the four hinge holes, and each of the four grooves is provided with a first inclined surface.

[0019] The beneficial effects of this utility model are:

[0020] 1. By rotatably setting the rotating protrusion in the hinge hole, one end of the dust cover is hinged to the outer shell, and the other end of the dust cover is snapped onto the snap protrusion by a buckle, making it easy to open and close the dust cover. The operation is simple and quick, and the dust cover is not easy to fall off or lose. The positioning and guiding function of the groove on the periphery of the installation opening and the cooperation between the first inclined surface and the second inclined surface make it easy to install the dust cover.

[0021] 2. The heat dissipation grooves extend to the perimeter of the outer casing. When multiple terminals are used side by side, the heat dissipation effect is affected because the outer casing surfaces of two adjacent terminals abut against each other. By aligning the heat dissipation grooves on two adjacent outer casings and forming a heat dissipation channel, the heat generated by the terminals can be dissipated along the heat dissipation channel, thereby improving the heat dissipation effect.

[0022] 3. After the wire is inserted into the first wiring slot of the conductor, by setting up a cable support platform, the contact area between the wire and the first wiring hole can be increased, the end of the wire can be better supported, the risk of the wire bending and breaking at the first wiring hole due to external force can be reduced, and the reliability of the wire connection can also be improved.

[0023] 4. By opening a label slot on the dust cover, multiple indicator labels are snapped into the label slot. The indicator labels can mark the wiring terminals. The indicator labels are snapped into the label receiving slot, which facilitates the installation, removal and replacement of the indicator labels. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0035] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0036] Example 1:

[0037] This embodiment provides a busbar terminal block, including:

[0038] The outer casing 1 has a mounting port 6 on one side of the outer casing 1 in the Z-axis direction, and first wiring holes 7 are provided on both sides of the outer casing 1 in the X-axis direction.

[0039] A conductor 2 is disposed inside the outer casing 1. Multiple first threaded holes 8 are formed on the conductor 2 along the Z-axis direction. A first wiring groove 9 is also formed on the conductor 2, which is directly opposite to the first wiring hole 7. The first threaded holes 8 are connected to the first wiring groove 9.

[0040] Multiple fastening screws 3 are threadedly connected to the first threaded hole 8;

[0041] A cover plate 4 is provided on the mounting port 6. The cover plate 4 has multiple first through holes 10, which are directly opposite to the first threaded hole 8. A receiving groove is formed between the cover plate 4 and the mounting port 6.

[0042] Dust cover 5 is set in the receiving groove, and reinforcing ribs 11 are provided on the periphery of the inner side of dust cover 5;

[0043] The dust cover 5 has two symmetrically arranged rotating protrusions 12 on one end in the X-axis direction, and a buckle 13 on the other end in the X-axis direction. The outer shell 1 has two symmetrically arranged hinge holes 14 near the mounting port 6. The outer shell 1 also has a snap-fit ​​protrusion 15 adapted to the buckle 13. The rotating protrusion 12 is rotatably disposed in the hinge hole 14, and the buckle 13 is snapped onto the snap-fit ​​protrusion 15. The mounting port 6 has a groove 16 near the hinge hole 14 on its periphery, and a first inclined surface 17 is provided on the groove 16. The rotating protrusion 12 has a second inclined surface 18 adapted to the first inclined surface 17.

[0044] In this technical solution, the outer shell 1 can be made of plastic, such as PVC, PE and PP, and the plastic shell can play an insulating role.

[0045] The outer casing 1 has a receiving cavity for accommodating the conductor 2. The receiving cavity is connected to the mounting port 6 and the first wiring hole 7. The conductor 2 can be a metal material with conductive properties, such as copper, which has excellent conductivity. The conductor 2 is installed into the receiving cavity of the outer casing 1 through the mounting port 6, and then the fastening screw 3 can be threaded into the first threaded hole 8 of the conductor 2.

[0046] Both sides of the outer casing 1 in the X-axis direction can be provided with snap-fit ​​holes, and the cover plate 4 can be snapped onto the outer casing 1 for easy installation.

[0047] In use, insert the end of the wire into the first wiring groove 9. A hexagonal groove 16 can be made on the fastening screw 3. By using a tool to pass through the first through hole 10 on the cover plate 4 and insert it into the hexagonal groove 16, the fastening screw 3 can be rotated. For example, by turning the fastening screw 3 with a screwdriver, the end of the wire is fixed in the first wiring groove 9. After the wires in the first wiring groove 9 on both sides of the X-axis direction are fixed, the circuit can be made conductive. The wire can be removed by rotating the fastening screw 3 in the opposite direction.

[0048] By engaging the rotating protrusion 12 with the hinge hole 14, the dust cover 5 is hinged to the mounting opening 6 of the outer casing 1, allowing the dust cover 5 to rotate on the outer casing 1. The rotating protrusion 12 on the dust cover 5 can be a cylindrical protrusion, which facilitates the smooth rotation of the rotating protrusion 12 within the hinge hole 14.

[0049] like Figure 4-5 As shown, the buckle 13 can be a conventional elastic buckle 13 with an inclined surface, and the engaging protrusion 15 can be a protrusion protruding from the surface of the outer shell 1. By pressing down on the dust cover 5, the buckle 13 deforms, causing the inclined surface of the buckle 13 to abut against the surface of the engaging protrusion 15, thereby engaging the dust cover 5 onto the outer shell 1 and accommodating it in the receiving groove. Placing the dust cover 5 in the receiving groove can protect the dust cover 5 and reduce impacts from external forces on both sides in the Y-axis direction.

[0050] like Figure 3 and Figure 6-7 As shown, when installing the dust cover 5 onto the outer casing 1, the second inclined surface 18 of the rotating protrusion 12 can be aligned with the first inclined surface 17 on the groove 16. The rotating protrusion 12 is then pressed into the groove 16 on the mounting opening 6 in the Z-axis direction. The groove 16 provides positioning and guidance, while the second inclined surface 18 abuts against and slides on the first inclined surface 17. Subsequently, the rotating protrusion 12 is installed into the hinge hole 14. The mutual cooperation between the two inclined surfaces facilitates the smooth and quick installation of the dust cover 5 onto the outer casing 1.

[0051] In summary, by rotatably setting the rotating protrusion 12 in the hinge hole 14, one end of the dust cover 5 is hinged to the outer shell 1, and the other end of the dust cover 5 is locked to the outer shell 1 by the buckle 13 and the locking protrusion 15. This makes it easy to open and close the dust cover 5, and the operation is simple and quick. The dust cover 5 is also less likely to fall off or be lost. The positioning and guiding function of the groove 16 on the periphery of the mounting port 6 and the cooperation between the first inclined surface 17 and the second inclined surface 18 make it easy to install the dust cover 5.

[0052] Example 2:

[0053] This embodiment provides a busbar terminal block, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0054] Two heat dissipation slots 19 are provided on both sides of the outer casing 1 along the Y-axis.

[0055] In this technical solution, the heat dissipation groove 19 extends to the periphery of the outer casing 1. When multiple terminals are used side by side, the heat dissipation effect is affected because the outer casing 1 surfaces of two adjacent terminals abut against each other. By aligning the heat dissipation grooves 19 on two adjacent outer casings 1 and forming a heat dissipation channel, the heat generated by the terminals can be discharged along the heat dissipation channel, thereby improving the heat dissipation effect.

[0056] Example 3:

[0057] This embodiment provides a busbar terminal block, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0058] A cable support platform 20 is provided on the outer casing 1 at the first wiring hole 7.

[0059] In this technical solution, after the wire is connected to the first wiring groove 9 of the conductor 2, the contact area between the wire and the first wiring hole 7 can be increased by setting the cable support platform 20, which can better support the end of the wire, reduce the risk of the wire bending and breaking at the first wiring hole 7 due to the influence of external force, and also improve the reliability of the wire connection.

[0060] Example 4:

[0061] This embodiment provides a busbar terminal block, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0062] The dust cover 5 has a label slot, and multiple indicator labels are snapped into the label slot; 21.

[0063] In this technical solution, the indicator label 21 can mark the wiring terminals, and the indicator label 21 can be made of plastic. A slot can be provided in the label receiving groove, and an elastic buckle 13 can be provided on the inside of the indicator label 21, so that the indicator label 21 can be snapped into the label receiving groove, which facilitates the installation, removal and replacement of the indicator label 21.

[0064] Example 5:

[0065] This embodiment provides a busbar terminal block, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0066] The cover plate 4 is provided with a second through hole 22, and the conductor 2 is also provided with a second threaded hole 23 opposite to the second through hole 22. The second threaded hole 23 is also provided with a fastening screw 3. The conductor 2 is also provided with a second wiring groove 24, and the second threaded hole 23 is connected to the second wiring groove 24.

[0067] In this technical solution, such as Figure 4As shown, the second wiring slot 24 is an open slot, and wires can be placed in the second wiring slot 24. By passing a screwdriver through the second through hole 22 and tightening the fastening screw 3, the conductor can be fixed. The number of wires can be increased by setting the second wiring slot 24.

[0068] Furthermore, the second wiring groove 24 is provided with anti-slip ridges 25, which are directly opposite the fastening screw 3.

[0069] In this technical solution, a flat surface is provided on the second wiring groove 24, which is directly opposite to the bottom end of the fastening screw 3. Anti-slip ridges 25 are provided on this flat surface. The anti-slip ridges 25 are used to increase the friction between the wire and the second wiring groove 24, thereby improving the stability of the wire connection.

[0070] Furthermore, a limiting protrusion ring 26 is provided on the periphery of both the first through hole 10 and the second through hole 22, and the inner diameter R1 of the limiting protrusion ring 26 is smaller than the diameter R2 of the fastening screw 3.

[0071] In this technical solution, the inner diameter R1 of the limiting protrusion ring 26 is smaller than the diameter R2 of the fastening screw 3, thereby limiting the fastening screw 3 and preventing it from being excessively unscrewed and causing it to come out.

[0072] Example 6:

[0073] This embodiment provides a busbar terminal block, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0074] There are two snap-fit ​​protrusions 15, which are respectively located on both sides of the outer shell 1 in the X-axis direction. There are four hinge holes 14, which are symmetrically located on both sides of the outer shell 1 in the Y-axis direction. Four grooves 16 are respectively provided on the periphery of the mounting port 6, which are close to the four hinge holes 14. Each of the four grooves 16 is provided with a first inclined surface 17.

[0075] In this technical solution, the two snap-fit ​​protrusions 15 can be divided into a first snap-fit ​​protrusion 15 and a second snap-fit ​​protrusion 15, and the hinge holes 14 can be divided into two groups, including a first hinge hole group 14 near the second snap-fit ​​protrusion 15 and a second hinge hole group 14 near the first snap-fit ​​protrusion 15.

[0076] When installing the dust cover 5, the rotating protrusion 12 of the dust cover 5 can be installed on the first set of hinge holes 14, and the buckle 13 can be snapped onto the first snap-fit ​​protrusion 15; the rotating protrusion 12 of the dust cover 5 can also be installed on the second set of hinge holes 14, and the buckle 13 can be snapped onto the second snap-fit ​​protrusion 15. Therefore, the dust cover 5 has two installation directions, and the installation direction can be selected arbitrarily, further improving the convenience of installation.
