Description

Technical Field

[0001] The utility model relates to the field of electrical components, in particular to a spliced ​​busbar. Background Art

[0002] The bus is a commonly used electrical device. The structure of the currently commonly used bus is shown in the patent publication document CN205376956U. There is a problem with the use of the bus with this structure, that is, the number of lower bus bars (numbered 5 in the figure in the document) of the bus with this structure is fixed, so it cannot be increased as needed in some usage scenarios, and its adaptability during use is poor. Utility Model Content

[0003] In view of the above problems, the present invention proposes a spliced ​​busbar, which is composed of conductive rods and single-group modules. A corresponding number of single-group modules can be mounted on the conductive rods as needed, making it more adaptable to use.

[0004] The technical solutions adopted by this utility model are as follows:

[0005] A spliced ​​busbar includes a base, a cover plate, a conductive rod, a conductive block and a conductive sheet, wherein the base is a base made of insulating material, the cover plate is a cover plate made of insulating material, a plurality of engaging grooves are provided on the base, and each engaging groove is provided with a through-hole on both sides, the conductive block is provided with an engaging hole, the conductive block is clamped in the engaging groove, the base and the cover plate are matched together, the conductive sheet is clamped between the base and the cover plate, the conductive rod and the through-hole clamp are matched together, the engaging hole and the conductive rod are clamped together, the conductive sheet is clamped between the conductive rod and the conductive block, the number of the conductive rods is equal to the number of the engaging grooves, the through-holes on both sides of the engaging grooves are on the same straight line, the conductive sheet is perpendicular to the conductive rod, and the conductive sheet is perpendicular to the conductive block.

[0006] In this combined busbar, the base, cover, conductive block and conductive sheet form a group of single modules, each of which is provided with a number of snap-in slots, and the number of snap-in slots in each single module is not less than 2 and not more than 4. Only one conductive block is installed in each single module, one end of the conductive block is clamped together with the conductive sheet, a part of the conductive sheet is clamped between the base and the cover, and a part of the conductive sheet is located between the base and the cover for conductive connection.

[0007] The method of using this type of combined bus is as follows: first, each group of single-group modules is placed on the conductive rod, and ensure that each engaging slot of each group of single-group modules is passed through by a conductive rod. If a conductive block is set in a certain engaging slot, the conductive block will be conductive with the conductive rod, and the conductive sheet will be clamped between the conductive rod and the conductive block. In this type of combined bus, the number of conductive rods is equal to the number of engaging slots in the single-group module. When using, the number of conductive rods and the number of single-group modules can be selected according to the required usage scenario. The single-group module is used to connect to the cable through its own conductive sheet, and the conductive rod is used to connect to the power supply cable. Therefore, when the cable connection needs to be increased, it can be achieved by placing more single-group modules on the conductive rod.

[0008] In summary, this type of busbar consists of a conductive rod and a single group of modules. A corresponding number of single groups of modules can be mounted on the conductive rod as needed, making it more adaptable to use.

[0009] Optionally, the through hole is a T-shaped through hole, and the conductive rod is a T-shaped conductive rod.

[0010] Optionally, the conductive block is provided with a side clamping hole, and the conductive sheet is engaged with the side clamping hole.

[0011] A side clamping hole is provided, and one end of the conductive rod is clamped in the side clamping hole, so as to improve the stability of the cooperation between the conductive rod and the conductive block.

[0012] Optionally, a notch step is provided on the base, and the conductive sheet is engaged with the notch step.

[0013] The function of the notch step is to clamp the conductive sheet to prevent the conductive sheet from sliding and deviating on the base.

[0014] Optionally, the conductive block is provided with a tightening hole, and the cover plate is provided with a mounting screw hole, and the number of the mounting screw holes is equal to the number of the engaging slots.

[0015] The function of the mounting screw hole is to install a screw or a bolt. When a screw or a bolt is installed in the mounting screw hole, the bolt or the screw will pass through the tightening hole to tighten the conductive sheet, so that the conductive rod and the conductive sheet are tightly attached together, ensuring that the fit between the conductive rod and the conductive sheet is more stable.

[0016] Optionally, the conductive sheet is provided with an arc-shaped recess, and the base is provided with an arc-shaped protrusion, and the protrusion and the recess cooperate together.

[0017] The conductive sheet has a recessed groove, and the base has a raised groove. The raised groove and the recessed groove fit together to prevent the conductive sheet from slipping out of the base. The raised groove and the recessed groove are both arc-shaped. This design ensures that the raised groove and the recessed groove fit together to reduce wear on the conductive sheet or the base.

[0018] Optionally, the engaging groove is a square engaging groove, and the conductive block is a square conductive block.

[0019] Optionally, a notch is provided on one side of the engaging hole, and hooks are provided on both sides of the notch, and the hooks are used to contact the conductive rod.

[0020] Because the conductive rod is a T-shaped conductive rod, in order to ensure that the conductive rod can be smoothly inserted into the engaging hole of the conductive block, a notch is set on one side of the engaging hole. The presence of the notch allows the conductive rod to slide smoothly relative to the conductive block. At the same time, the T-shaped conductive rod has a protrusion relative to the round or square rod, so hooks are set on both sides of the notch. The hooks on both sides respectively hook the two protrusions, thereby clamping the conductive sheet and the conductive rod in the engaging hole of the conductive block.

[0021] The beneficial effects of the utility model are as follows: the busbar is composed of a conductive rod and a single group of modules, and a corresponding number of single groups of modules can be sleeved on the conductive rod as needed, so the busbar has stronger adaptability.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention.

For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0033] As attached Figure 1 ~Attached Figure 5As shown, a spliced ​​busbar includes a base 1, a cover plate 5, a conductive rod 2, a conductive block 3 and a conductive sheet 4. The base 1 is a base 1 made of insulating material, the cover plate 5 is a cover plate 5 made of insulating material, a plurality of engaging grooves 101 are provided on the base 1, and each engaging groove 101 is provided with a through hole 102 on both sides. The conductive block 3 is provided with an engaging hole 303. The conductive block 3 is clamped in the engaging groove, the base 1 is matched with the cover plate, the conductive sheet 4 is clamped between the base 1 and the cover plate, the conductive rod 2 is clamped and matched with the through hole 102, the engaging hole 303 is clamped and matched with the conductive rod 2, the conductive sheet 4 is clamped between the conductive rod 2 and the conductive block 3, the number of the conductive rods 2 is equal to the number of the engaging grooves 101, the through holes 102 on both sides of the engaging groove 101 are on the same straight line, the conductive sheet 4 is perpendicular to the conductive rod 2, and the conductive sheet 4 is perpendicular to the conductive block 3.

[0034] In this modular busbar, the base 1, the cover 5, the conductive block 3 and the conductive sheet 4 form a group of single modules, each of which is provided with a plurality of engaging slots 101, and the number of engaging slots 101 in each single module is not less than 2 and not more than 4. Only one conductive block 3 is installed in each single module, one end of the conductive block 3 is clamped together with the conductive sheet 4, a portion of the conductive sheet 4 is clamped between the base 1 and the cover 5, and a portion of the conductive sheet 4 is located between the base 1 and the cover 5 for conducting.

[0035] The method of using this type of combined bus is as follows: first, each group of single-group modules is sleeved on the conductive rod 2, and ensure that each engaging slot 101 of each group of single-group modules is passed through by a conductive rod 2. If a conductive block 3 is set in a certain engaging slot 101, the conductive block 3 will be conductive with the conductive rod 2, and the conductive sheet 4 will be clamped between the conductive rod 2 and the conductive block 3. In this type of combined bus, the number of conductive rods 2 is equal to the number of engaging slots 101 in the single-group module. When in use, the number of conductive rods 2 and the number of single-group modules can be selected according to the required usage scenario. The single-group module is used to connect to the cable through its own conductive sheet 4, and the conductive rod 2 is used to connect to the power supply cable. Therefore, when the cable connection needs to be increased, it can be achieved by sleeved more single-group modules on the conductive rod 2. The length of the conductive rod 2 can be designed and matched according to the needs of the usage scenario.

[0036] In summary, this type of busbar consists of a conductive rod 2 and a single group of modules. A corresponding number of single groups of modules can be mounted on the conductive rod 2 as needed, which makes it more adaptable to use.

[0037] In this busbar, since the conductive sheet is perpendicular to the conductive rod and the conductive block, the conductive sheet can be easily inserted into the conductive block during assembly. At the same time, the conductive rod can be smoothly inserted into the conductive block, reducing the probability of interference between the conductive rod and the conductive sheet.

[0038] Combined with attachment Figure 1 ~Attached Figure 5 As shown in the following, the usage of this combined busbar is described in detail. Figure 1 The single module shown in the figure has four engaging slots 101, which means that the busbar disclosed in this embodiment requires four Figure 2 The conductive rods 2 shown in the figure represent three live wires (A\B\C three-phase) and one neutral wire (N phase). When combined, each single module is provided with a conductive block 3. When each single module is mounted on the four conductive rods 2, the conductive block 3 in each single module is in a conductive state with the conductive rod 2. Figure 1 The single module shown in the figure is suitable for current scenarios with relatively large power consumption, such as shopping malls or factories, which require three live wires and one neutral wire. Figure 1 Take the single module shown in the figure as an example. Figure 1 The single-group module has four engaging slots 101, which means there are four rows of through holes 102, which clamp four conductive rods 2 from top to bottom, namely A\B\C\N. If the conductive block 3 of one of the single-group modules is set in the first engaging slot 101, the single-group module is connected to the A-phase conductive rod 2. If the conductive block 3 of another single-group module is set in the fourth engaging slot 101, the single-group module is connected to the N-phase conductive rod 2.

[0039] The assembly method of this busbar is as follows: first, place the first conductive block 3 into one of the engaging slots 101 of the base 1, and then insert the conductive sheet 4 into the conductive block 3, and then cover the cover 5 so that the conductive sheet 4 is clamped between the base 1 and the cover 5. At this time, the assembly of the single-group module is completed, and then prepare four conductive rods 2, and set the single-group module on the four conductive rods 2. Then, set the corresponding number of single-group modules as needed. After the single-group modules are set, screws are screwed into the corresponding mounting screw holes 501 on each cover 5, and the screws are used to tighten the conductive sheet 4, so that the conductive sheet 4 is pressed tightly against the conductive rod 2.

[0040] As attached Figure 1 ~Attached Figure 5 As shown, the insertion hole 102 is a T-shaped insertion hole 102 , and the conductive rod 2 is a T-shaped conductive rod 2 .

[0041] The T-shaped conductive rod 2 and the T-shaped through hole 102 have good matching stability after being matched together.

[0042] As attached Figure 1 ~Attached Figure 5 As shown, the conductive block 3 is provided with a side clamping hole 301 , and the conductive sheet 4 is engaged with the side clamping hole 301 .

[0043] A side clamping hole 301 is provided, and one end of the conductive rod 2 is clamped in the side clamping hole 301 , so as to improve the stability of the cooperation between the conductive rod 2 and the conductive block 3 .

[0044] As attached Figure 1 ~Attachment Figure 5 As shown, a notch step is provided on the base 1, and the conductive sheet 4 is engaged with the notch step.

[0045] The function of the notch step is to clamp the conductive sheet 4 to prevent the conductive sheet 4 from sliding and deviating on the base 1 .

[0046] As attached Figure 1 ~Attachment Figure 5 As shown, the conductive block 3 is provided with a tightening hole 302 , and the cover plate 5 is provided with a mounting screw hole 501 . The number of the mounting screw holes 501 is equal to the number of the engaging slots 101 .

[0047] The function of the mounting screw hole 501 is to install a screw or a bolt. When a screw or a bolt is installed in the mounting screw hole 501, the bolt or the screw will pass through the tightening hole 302 to tighten the conductive sheet 4, so that the conductive rod 2 and the conductive sheet 4 are tightly attached together, ensuring that the fit between the conductive rod 2 and the conductive sheet 4 is more stable.

[0048] As attached Figure 1 ~Attachment Figure 5 As shown, the conductive sheet 4 is provided with an arc-shaped recess 401 , and the base 1 is provided with an arc-shaped protrusion 104 , which is matched with the recess 401 .

[0049] The conductive sheet 4 has a recess 401, and the base 1 has a protrusion 104. The protrusion 104 and the recess 401 fit together to prevent the conductive sheet 4 from slipping off the base 1. The protrusion 104 is arc-shaped, and the recess 401 is also arc-shaped. This design ensures that the protrusion 104 and the recess 401 cooperate to reduce wear on the conductive sheet 4 or the base 1.

[0050] Optionally, the engaging groove 101 is a square engaging groove 101 , and the conductive block 3 is a square conductive block 3 .

[0051] As attached Figure 1 ~Attachment Figure 5 As shown, a notch is provided on one side of the engaging hole 303 , and hooks 3031 are provided on both sides of the notch. The hooks 3031 are used to contact the conductive rod 2 .

[0052] Because the conductive rod 2 is T-shaped, a notch is provided on one side of the engaging hole 303 to ensure that the conductive rod 2 can be smoothly inserted into the engaging hole 303 of the conductive block 3. The notch allows the conductive rod 2 to slide smoothly relative to the conductive block 3. Furthermore, the T-shaped conductive rod 2 has a protrusion compared to a round or square rod, so hooks 3031 are provided on either side of the notch. The hooks 3031 on either side respectively hook onto the two protrusions, thereby clamping the conductive sheet 4 and the conductive rod 2 within the engaging hole 303 of the conductive block 3. When a screw is installed in the mounting screw hole 501, one side of the conductive sheet 4 is tightened by the bolt or screw, while the protrusion on the conductive rod 2 is hooked by the hook 3031. Thus, the conductive sheet 4 and the conductive rod 2 are clamped together by the hook 3031 and the screw.

[0053] It is necessary to further explain the Figure 1 The single module shown in the figure is suitable for occasions with large power consumption. For scenes with small power consumption, such as home occasions, only the following modules are needed. Figure 6 The household module shown in FIG can be used. This household module has only two rows of through holes 102, which are used to cooperate with two conductive rods 2 (the two conductive rods 2 are respectively connected to the neutral wire and the live wire).

[0054] The above-described embodiments only express some embodiments of the present invention. The description is relatively specific and detailed, but it should not be understood as limiting the scope of the patent of the present invention. It should be pointed out that for those skilled in the art, it is still possible to modify the technical solutions described in the above-mentioned embodiments or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this utility model should be included in the scope of protection of this utility model.
