Description

Technical Field

[0001] The invention relates to the field of electrical product accessories, and in particular to a spliced ​​busbar device. Background Art

[0002] The bus is a commonly used electrical component. The structure of the bus currently used is roughly as shown in the patent announcement document CN213989489U. The bus shown in this structure is a fixed bus and can only adapt to a specific power usage situation. As shown in the attached figure of the document, there are two pins, so this bus can only be matched with a P+N (i.e., one live wire plus one neutral wire) circuit breaker. If the corresponding circuit breaker is three live wires or two live wires, this bus cannot be matched and used, so its versatility is relatively poor. Summary of the invention

[0003] In view of the above problems, the present invention proposes a spliced ​​busbar device, in which the power connection plates on the docking blocks are used to directly or indirectly connect to the circuit breaker. The number of docking blocks and the number of supporting conductive rods can be increased or decreased according to usage requirements, and the entire device has stronger versatility.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A spliced ​​busbar device comprises a connector seat and a docking block, wherein the docking seat is provided with a main clamping hole and a side clamping hole, wherein the main clamping hole clamps a main conductive rod, wherein the side clamping hole clamps a branch conductive rod, wherein the number of the main conductive rods is not less than the number of the branch conductive rods, and each branch conductive rod is electrically connected to a main conductive rod, wherein the docking blocks are provided with a through hole, wherein each docking block is sleeved on the branch conductive rod through its through hole, and wherein each docking block is provided with an electrical connection sheet, and each electrical connection sheet is electrically connected to one of the branch conductive rods.

[0006] Specifically in this type of busbar device, a main clamping hole is provided in the main clamping hole of the docking seat, and a main conductive rod is clamped in each main clamping hole. Since there are three live wires and one neutral wire, each docking seat is provided with no less than four main clamping holes, and there are four main conductive rods in total. Each main conductive rod is clamped in one of the main clamping holes, and the four main conductive rods are A\B\C (three live wires) and N (one neutral wire).

[0007] The side card holes of the specific docking seat are provided with four side card holes, and the number of branch conductive rods can be selected according to the needs of use. If it is a household electricity scene, only two branch conductive rods are required. The two branch conductive rods are respectively inserted in the two side card holes, one of which is connected to the main conductive rod N, and the other branch conductive rod is connected to any one of the three main conductive rods A\B\C. When the usage scenario is a shopping mall or factory, four branch conductive rods are configured. The four branch conductive rods represent the three live wires A\B\C and one neutral wire N. Since the branch conductive rods are inserted into the side card holes, the number of branch conductive rods on each docking seat can be increased or decreased as needed. When used in a household scenario, two branch conductive rods are used, and when used in shopping malls, factories and other occasions, four branch conductive rods are used.

[0008] The use of this busbar device is as follows. When using it, the number of docking blocks is selected according to the number of circuit breakers. Taking the use scenario of a shopping mall as an example, a number of docking blocks are mounted on the supporting conductive rods. Each docking block has four through holes, and the four through holes are respectively matched with four supporting conductive rods. Each docking block has a connecting piece, and each connecting piece is only in a conductive state with one conductive rod. The connecting piece is used to directly or indirectly connect to the circuit breaker.

[0009] In summary, the connecting piece on the docking block in this busbar device is used to connect directly or indirectly to the circuit breaker, and the number of docking blocks and the number of supporting conductive rods can be increased or decreased according to usage needs, making the entire device more versatile.

[0010] Specifically, in this type of busbar device, there are two types of connector seats. One type is that side clamping holes are provided on both sides of the main clamping hole. Both ends of this type of connector seat can be clamped and inserted into the supporting conductive rod, so that the supporting conductive rod is provided on both sides of the main conductive rod. The other type of connector seat is that only one side of the supporting clamping hole is provided with a side clamping hole. Only one end of this type of connector seat can be used to clamp and insert the supporting conductive rod, so that only one side of the main conductive rod is provided with a supporting conductive rod.

[0011] Specifically in this type of busbar device, in order to achieve conduction between the main conductive rod and the branch conductive rod, a connecting piece is provided inside the joint seat, and the connecting piece connects the main conductive rod and the branch conductive rod.

[0013] Optionally, a sleeve seat is also included, and both ends of the sleeve seat are respectively engaged with a connector seat clamp.

[0014] Specifically in this type of socket, the two ends of the socket are respectively matched with the connector clamp. When in use, the two connectors at both ends of the socket are respectively fixed to the distribution box or the wall of the building by fasteners such as screws. However, when one of the connectors needs to be slid, one of the connectors can be released from the distribution box or the wall of the building, and then the connector can be moved.

[0015] Specifically in this type of busbar device, the sleeve seat is provided with a snap-fitting groove, and the joint seat is provided with a step ring, and the joint seat is snap-fitted with the snap-fitting groove of the sleeve seat through its own step ring.

[0016] In this type of busbar, a channel is provided inside the socket, and the channel inside the socket is used for the main conductive rod to pass through.

[0017] Optionally, the socket includes an outer sleeve and an inner tube body, the outer tube body is slidably mounted on the inner tube body, one end of the inner tube body is engaged with a connector clamp, and one end of the outer sleeve is engaged with another connector clamp.

[0018] Specifically, both the outer sleeve and the inner tube body are provided with engaging grooves, and the passage for the main conductive rod to pass through is located inside the inner tube body.

[0019] Optionally, an annular recess is formed at one end of the docking block, and a raised ring is formed at the other end of the docking block, and the annular recess and the raised ring are respectively located on two sides of the through hole.

[0020] Because multiple docking blocks are required in this busbar device, in order to ensure that two adjacent docking blocks remain stable when in contact, a raised ring and a ring groove are respectively opened at both ends of the docking block. The two adjacent docking blocks are matched together through the raised ring and the ring groove. In this way, the matching stability of the two adjacent docking blocks can be ensured, and the exposure area of ​​the supporting conductive rod in the air can be reduced to ensure safety.

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 drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0042] As attached Figure 1 , 2 As shown in , 3 and 6, a spliced ​​busbar device includes a connector seat 3 and a docking block 4, the docking seat is provided with a main clamping hole 3012 and a side clamping hole 3013, the main clamping hole 3012 is clamped with a main conductive rod, and the side clamping hole 3013 is clamped with a branch conductive rod, the number of the main conductive rods is not less than the number of the branch conductive rods, and each branch conductive rod is in an electrically connected state with a main conductive rod, there are multiple docking blocks 4, each of which is provided with a through hole, each of which is sleeved on the branch conductive rod through its own through hole, and each of which is provided with an electrical connection sheet 401, and each electrical connection sheet 401 is electrically connected to one of the branch conductive rods.

[0043] Specific attachment Figure 1 With attached Fig. 9 The main conductive rod and the auxiliary conductive rod are not drawn.

[0044] Specifically in this type of busbar device, a main clamping hole is provided in the main clamping hole of the docking socket, and a main conductive rod is clamped in each main clamping hole. Since there are three live wires and one neutral wire, each docking socket is provided with no less than four main clamping holes, and there are four main conductive rods in total. Each main conductive rod is clamped in one of the main clamping holes. The four main conductive rods are A\B\C (three live wires) and N (one neutral wire).

[0045] The side card holes 3013 of the specific docking seat are provided with four side card holes 3013, and the number of supporting conductive rods can be selected according to the needs of use. If it is a household electricity scene, only two supporting conductive rods are required. The two supporting conductive rods are respectively inserted in the two side card holes 3013, one of which is connected to the main conductive rod N, and the other is connected to any one of the three main conductive rods A\B\C. When the usage scene is a shopping mall or factory, four supporting conductive rods are configured, and the four supporting conductive rods represent the three live wires A\B\C and one neutral wire N. Since the supporting conductive rods are inserted in the side card holes 3013, the number of supporting conductive rods on each docking seat can be increased or decreased as needed. When used in a household scene, two supporting conductive rods are used, and when used in shopping malls, factories and other occasions, four supporting conductive rods are used.

[0046] The use of this busbar device is as follows. When using it, the number of docking blocks 4 is selected according to the number of circuit breakers. Taking the use scenario of a shopping mall as an example, a number of docking blocks 4 are mounted on the supporting conductive rods. Each docking block 4 is provided with four through holes, and the four through holes are respectively matched with four supporting conductive rods. Each docking block 4 is provided with a power connection sheet 401, and each power connection sheet 401 is only in a conductive state with one conductive rod. The power connection sheet 401 is used to directly or indirectly connect to the circuit breaker.

[0047] See attached Figure 3 , 4 As shown in Figure 5, the specific connector seat 3 includes a seat bottom 301 and a seat plate 302. The seat plate 302 and the seat bottom 301 are detachably matched together. The seat plate 302 is used to cover the seat bottom 301. The main clamping hole 3012 and the side clamping hole 3013 are both opened on the seat bottom 301. The connecting piece 303 is clamped in different grooves of the seat plate 302. There are four connecting pieces 303 in each seat plate 302, and the four connecting pieces 303 are in a parallel and non-contact state.

[0048] In summary, the power connection plate 401 on the docking block 4 in this busbar device is used to directly or indirectly connect to the circuit breaker. The number of docking blocks 4 and the number of supporting conductive rods can be increased or decreased according to usage requirements, and the entire device is more versatile.

[0049] Specifically, in this busbar device, there are two types of connector base 3. One type is that both sides of the main clamp hole are provided with side clamp holes 3013. In this type of connector base 3, both ends can be clamped and inserted into the supporting conductive rod, so that both sides of the main conductive rod are provided with supporting conductive rods. Another type of connector base 3 is that only one side of the supporting clamp hole is provided with a side clamp hole 3013. In this type of connector base 3, only one end can be used to clamp and insert the supporting conductive rod, so that only one side of the main conductive rod is provided with a supporting conductive rod.

[0050] In the specific busbar device, the connector seat 3 having side clamping holes 3013 on both sides is a cross-shaped connector seat 3 (structure as shown in the attached figure). Figure 3 As shown), and the one with the side clamping hole 3013 on one side is a T-shaped connector seat 3 (structure as shown in the attached Figure 8 The internal structures of the two are basically the same, except that the T-shaped connector seat 3 has one less row of side clamping holes 3013 than the cross-shaped connector seat 3. The specific state of the cross-shaped connector seat 3 when in use is roughly as shown in the attached Figure 1 As shown in the figure, the state of the T-shaped connector when in use is roughly as shown in the figure. Fig. 9 shown.

[0051] Specifically in this busbar device, in order to achieve conduction between the main conductive rod and the branch conductive rod, a connecting piece 303 is provided inside the connector seat 3, and the connecting piece 303 connects the main conductive rod and the branch conductive rod. In the entire connector seat 3, except for the connecting piece 303 which is made of conductive material, the rest are all made of insulating material (such as plastic).

[0052] Likewise, the docking block 4 is made entirely of insulating material (such as plastic), while the power strip 401 on the docking block 4 is made of conductive material (which may be copper).

[0053] As attached Figure 2 As shown, it also includes a sleeve seat 2, and the two ends of the sleeve seat 2 are respectively clamped together with a joint seat 3.

[0054] Specifically in this type of socket 2, the two ends of the socket 2 are respectively clamped together with the connector seat 3. When in use, the two connector seats 3 at the two ends of the socket 2 are respectively fixed to the distribution box or the wall of the building by fasteners such as screws. However, when one of the connector seats 3 needs to be slid, one of the connector seats 3 can be released from the distribution box or the wall of the building, and then the connector seat 3 can be moved.

[0055] Specifically in this busbar device, the socket 2 is provided with a snap-fitting groove 201 , and the connector seat 3 is provided with a step ring 3011 . The connector seat 3 is snap-fitted with the snap-fitting groove 201 of the socket 2 via its own step ring 3011 .

[0056] In this busbar, a channel is provided inside the socket 2, and the channel inside the socket 2 is for the main conductive rod to pass through.

[0057] As attached Figure 2 As shown, the sleeve seat 2 includes an outer sleeve 202 and an inner tube body 203. The outer tube body is slidably mounted on the inner tube body 203. One end of the inner tube body 203 is clamped together with a joint seat 3, and one end of the outer sleeve 202 is clamped together with another joint seat 3.

[0058] Specifically, both the outer sleeve 202 and the inner tube body 203 are provided with a locking groove 201 , and a passage for the main conductive rod to pass through is located inside the inner tube body 203 .

[0059] Specifically, in order to improve the matching stability between the outer sleeve 202 and the inner tube body 203, a plurality of slides 2021 are provided on the inner wall of the outer sleeve 202, the slides 2021 are in a parallel and non-contacting state, and a slide groove 2031 is provided on the inner tube body 203, and the slides 2021 and the slide groove 2031 slide and fit together tightly. The existence of the slides 2021 and the slide groove 2031 can improve the matching stability between the inner tube body 203 and the outer sleeve 202, and ensure that the probability of jamming when the two slide relative to each other is lower.

[0060] As attached Figure 6 As shown, a ring recess 4032 is formed at one end of the docking block 4, and a raised ring 4031 is formed at the other end of the docking block 4. The ring recess 4032 and the raised ring 4031 are respectively located at two sides of the through hole.

[0061] Because multiple docking blocks 4 are required in this busbar device, in order to ensure that two adjacent docking blocks 4 remain stable when in contact, a raised ring 4031 and a ring groove 4032 are respectively provided at both ends of the docking block 4. The two adjacent docking blocks 4 are matched together through the raised ring 4031 and the ring groove 4032. In this way, the matching stability of the two adjacent docking blocks 4 can be ensured, and the exposure area of ​​the supporting conductive rod in the air can be reduced to ensure safety.

[0062] As attached Figure 1 As shown, it also includes a wiring seat 1, which is provided with a clamping hole 101 and a wiring hole 102. The clamping hole 101 is clamped and matched with the main conductive rod. A wiring frame is arranged in the wiring seat 1 (located in the wiring seat 1, not shown in the drawings), one end of the wiring frame is matched with the main conductive rod, and the other end of the wiring frame is located at the wiring hole 102.

[0063] The specific function of the wiring seat 1 is to connect the power line. The entire wiring seat 1 is made of insulating material, and the wiring frame is made of conductive material.

[0064] As attached Figure 6 As shown, the docking block 4 is a cuboid-shaped docking block 4 .

[0065] Attached Figure 6 With attached Figure 7 The docking block 4 shown in the figure is provided with four through holes, which is adapted to the current use scenario of three phase lines and one neutral line. Therefore, when four through holes are provided, the power connection piece 401 has four different engagement positions on the block bottom 403. Figure 7 The four different display positions are shown from left to right. Compared with the current home scene, only two conductive rods are needed. Fig.10 The household docking block 4 shown in FIG. 4 has only two through holes.

[0066] Specifically, the docking block 4 includes a block bottom 403 and a block cover 402 , and the electrical connection piece 401 is stuck in a groove of the block bottom 403 .

[0067] The main conductive rods are in a parallel state, and the branch conductive rods are in a parallel state.

[0068] The branch conductive rod is perpendicular to the main conductive rod.

[0069] In order to prevent the main conductive rod from being exposed, a cover sheet 5 may be clamped on the connector seat 3 or the sleeve tube at the end.

[0070] Specifically, the cover sheet is made of insulating material, and the outer sleeve and the inner tube body are also made of insulating material.

[0071] Specifically, both the main conductive rod and the branch conductive rod can be round rods, and the diameter of the main conductive rod is greater than the diameter of the branch conductive rod.
