Description

Technical Field

[0001] The utility model relates to the field of electrical components, in particular to a modular 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 modular spliced ​​busbar, which is composed 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, which has stronger adaptability.

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

[0005] A modular spliced ​​busbar includes a base, a cover, a conductive rod, a conductive block and a conductive sheet. The base is made of an insulating material, the cover is made of an insulating material, a plurality of engaging grooves are provided on the base, and each engaging groove is provided with through holes on both sides. The conductive block is provided with engaging holes, the conductive block is clamped in the engaging grooves, the base is matched with the cover, the conductive sheet is clamped between the base and the cover, the conductive rod is clamped with the through hole, the engaging hole is clamped with the conductive rod, and the conductive sheet is clamped between the conductive rod and the conductive block.

[0006] In this busbar, the base, cover, conductive block and conductive sheet form a group of single-group modules, each of which is provided with a number of snap-in slots, and the number of snap-in slots in each single-group module is not less than 2 and not more than 4. Only one conductive block is installed in each single-group 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 with the cable, and the conductive rod is used to connect with 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 combined busbar is composed 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, a clamping hole is provided on the conductive block, and the clamping hole is located on one side of the locking hole, and one end of the conductive sheet is fitted into the clamping hole.

[0010] A clamping hole is provided on the conductive block, and the clamping hole is located on one side of the hole wall of the clamping hole. One end of the conductive sheet is clamped in the clamping hole, which can improve the stability of the conductive sheet between the conductive rod and the conductive block.

[0011] Optionally, the conductive block is provided with a tightening hole, the tightening hole is in communication with the engaging hole, and the cover plate is provided with a mounting screw hole.

[0012] 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 press the conductive sheet tightly, 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.

[0013] Optionally, the through-holes are square through-holes, and the conductive rods are square conductive rods.

[0014] The square conductive rods are inserted into the square through holes, which can improve the matching stability between the single module and the conductive rods.

[0015] Optionally, a snap-fitting notch is provided on the base, and the conductive sheet fits together with the snap-fitting notch.

[0016] Since the conductive sheet is clamped between the base and the cover, a clamping notch is provided on the base, and the conductive sheet and the clamping notch are clamped together to ensure that the conductive sheet will not be deflected when released between the base and the cover.

[0017] Optionally, a protrusion is provided on the base, and a recess is provided on the conductive sheet, and the recess cooperates with the protrusion.

[0018] When the protrusion and the recess on the base fit together, a locking limit is formed between the base and the conductive sheet. The locking limit can ensure that the conductive sheet cannot slide relative to the base, ensuring the stability of the clamping fit between the conductive sheet, the conductive rod and the conductive block.

[0019] Optionally, the engaging groove is a square engaging groove, and the conductive block is a square conductive block.

[0020] Optionally, the through holes on both sides of each engaging groove are located on the same straight line.

[0021] Optionally, the conductive sheet is perpendicular to the conductive block.

[0022] The beneficial effects of the utility model are that: it is composed of a conductive rod and a single group of modules, and a corresponding number of single group modules can be sleeved on the conductive rod as needed, so the utility model has stronger adaptability.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

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.

[0035] As attached Figure 1 ~Attachment Figure 6 As shown, a modular 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 102 are provided on the base 1, and each engaging groove 102 is provided with a through hole 101 on both sides. The conductive block 3 is provided with an engaging hole 301, 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 101, the engaging hole 301 is clamped and matched with the conductive rod 2, and the conductive sheet 4 is clamped between the conductive rod 2 and the conductive block 3.

[0036] In this combined 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 102, and the number of engaging slots 102 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 part of the conductive sheet 4 is clamped between the base 1 and the cover 5, and a part of the conductive sheet 4 is located between the base 1 and the cover 5 for conducting.

[0037] The method of using this type of bus is as follows: first, each group of single-group modules is placed on the conductive rod 2, and it is ensured that each engaging slot 102 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 102, 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 102 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 with the cable, and the conductive rod 2 is used to connect with 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 2. The length of the conductive rod 2 can be designed as needed.

[0038] In summary, this combined busbar is composed 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.

[0039] Combined with attachment Figure 1 ~Attached Figure 4 As shown in the following, the usage of this combined busbar is described in detail. Figure 1 The single module shown in FIG. 1 has four engaging slots 102, 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 1The single-group module has four engaging slots 102, which means there are four rows of through holes 101, 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 102, 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 102, the single-group module is connected to the N-phase conductive rod 2.

[0040] The assembly method of this busbar is as follows: first, place the first conductive block 3 into one of the engaging slots 102 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, and 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.

[0041] As attached Figure 1 ~Attachment Figure 6 As shown, a clamping hole 302 is provided on the conductive block 3 , and the clamping hole 302 is located on one side of the engaging hole 301 , and one end of the conductive sheet 4 is fitted into the clamping hole 302 .

[0042] A clamping hole 302 is provided on the conductive block 3, and the clamping hole 302 is located on one side of the hole wall of the clamping hole 301. One end of the conductive sheet 4 is clamped in the clamping hole 302, which can improve the stability of the conductive sheet 4 between the conductive rod 2 and the conductive block 3.

[0043] As attached Figure 1 ~Attachment Figure 6 As shown, the conductive block 3 is provided with a tightening hole 303 , the tightening hole 303 is in communication with the engaging hole 301 , and the cover plate 5 is provided with a mounting screw hole 501 .

[0044] The function of the mounting screw hole 501 is to install a screw or bolt. When a screw or bolt is installed in the mounting screw hole 501, the bolt or screw will press the conductive sheet 4 tightly, so that the conductive rod 2 and the conductive sheet 4 are tightly together, ensuring that the fit between the conductive rod 2 and the conductive sheet 4 is more stable.

[0045] As attached Figure 1 ~Attachment Figure 6 As shown, the through hole 101 is a square through hole 101 , and the conductive rod 2 is a square conductive rod 2 .

[0046] The square conductive rod 2 is locked in the square through hole 101 , which can improve the matching stability between the single module and the conductive rod 2 .

[0047] As attached Figure 1 ~Attachment Figure 6 As shown, a snap-fitting notch 103 is provided on the base 1 , and the conductive sheet 4 fits in the snap-fitting notch 103 .

[0048] Since the conductive sheet 4 is clamped between the base 1 and the cover 5 , a locking notch 103 is provided on the base 1 , and the conductive sheet 4 is locked with the locking notch 103 to ensure that the conductive sheet 4 is released between the base 1 and the cover 5 without any hysteresis.

[0049] As attached Figure 1 ~Attachment Figure 6 As shown, a protrusion 104 is provided on the base 1 , and a recess 401 is provided on the conductive sheet 4 , and the recess 401 cooperates with the protrusion 104 .

[0050] When the protrusion 104 on the base 1 is fitted together with the recess 401, a locking limit is formed between the base 1 and the conductive sheet 4. The locking limit can ensure that the conductive sheet 4 cannot slide relative to the base 1, thereby ensuring the stability of the clamping fit between the conductive sheet 4, the conductive rod 2 and the conductive block 3.

[0051] As attached Figure 1 ~Attachment Figure 6 As shown, the engaging groove 102 is a square engaging groove 102 , and the conductive block 3 is a square conductive block 3 .

[0052] As attached Figure 1 ~Attachment Figure 6 As shown, the through holes 101 on both sides of each engaging groove 102 are located on the same straight line.

[0053] As attached Figure 1 ~Attachment Figure 6 As shown, the conductive sheet 4 is perpendicular to the conductive block 3 .

[0054] 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 7 The household module shown in FIG can be used. This household module has only two rows of through holes 101, which are used to cooperate with two conductive rods 2 (the two conductive rods 2 are connected to the neutral wire and the live wire respectively).

[0055] 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.
