Description

Technical Field

[0001] The utility model relates to the field of electrical product accessories, 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, it has 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 has three live wires or two live wires, this bus cannot be matched and used, so its versatility is relatively poor. Utility Model Content

[0003] In response to the above problems, the utility model proposes a spliced ​​busbar device. The power connection plate on the docking block is 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 needs, and the entire device is more versatile.

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

[0005] A spliced ​​busbar device includes a connector seat and a docking block, the connector seat is provided with a main clamping hole and a side clamping hole, the main clamping hole is clamped with a main conductive rod, and the side clamping hole 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 electrically connected to a main conductive rod, the docking blocks are multiple, each of the docking blocks is provided with a through hole, each docking block is sleeved on the branch conductive rod through its own through hole, and each docking block is provided with an electrical connection piece, and each electrical connection piece 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 connector seat, and a main conductive rod is clamped in each main clamping hole. Since there are three live wires and one neutral wire, each connector seat has 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).

[0007] The specific connector seat has four side card holes, and the number of branch conductive rods can be selected according to usage needs. If it is a household power scenario, only two branch conductive rods are required. The two branch conductive rods are respectively inserted into the two side card holes, 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 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 the neutral wire N. Since the branch conductive rods are inserted into the side card holes, the number of branch conductive rods on each connector 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, etc., four branch conductive rods are used.

[0008] The usage 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 usage scenario in a shopping mall as an example, several docking blocks are placed 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.

In this type of connector block, 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. The other type of connector block has a side clamping hole on only one side of the supporting clamping hole. In this type of connector block, 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.

[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 connector seat, which connects the main conductive rod and the branch conductive rod. In the entire connector seat, except for the connecting piece which is made of conductive material, the rest is made of insulating material (such as plastic).

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

[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 busbar device, the sleeve seat is provided with a snap-fitting groove, and the connector seat is provided with a step ring. The connector seat is snap-fitted with the snap-fitting groove of the sleeve seat via its own step ring.

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

[0017] Optionally, the socket includes an outer sleeve and an inner tube body, the outer sleeve 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 in the inner tube body.

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

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

[0021] Optionally, it also includes a wiring seat, which is provided with a clamping hole and a wiring hole, the clamping hole is clamped and matched with the main conductive rod, and a wiring frame is provided in the wiring seat, 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.

[0039] 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.

[0040] 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.

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.

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

[0043] Specific attached Figure 1 With attached Figure 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 connector seat, and a main conductive rod is clamped in each main clamping hole. Since there are three live wires and one neutral wire, each connector seat has 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 connector seat are provided with four side card holes 3013, 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 into 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 scenario is a shopping mall or factory, four branch conductive rods are configured, and 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 3013, the number of branch conductive rods on each connector seat can be increased or decreased as needed. When used in a household scene, two branch conductive rods are used, and when used in shopping malls, factories and other occasions, four branch conductive rods are used.

[0046] The usage 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 usage scenario in a shopping mall as an example, several docking blocks 4 are mounted on the supporting conductive rods. Each docking block 4 has four through holes, and the four through holes are respectively matched with four supporting conductive rods. Each docking block 4 has a power connection piece 401, and each power connection piece 401 is only in a conductive state with one conductive rod. The power connection piece 401 is used to directly or indirectly connect to the circuit breaker.

[0047] See attached Figure 3 、 4As 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 card hole 3012 and the side card hole 3013 are both opened on the seat bottom 301. The connecting piece 303 is stuck in different grooves of the seat plate 302. There are four connecting pieces 303 in each seat plate 302. The four connecting pieces 303 are in a parallel and non-contact state.

[0048] In summary, the power connection piece 401 on the docking block 4 in this busbar device is used to connect directly or indirectly 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 needs, making the entire device more versatile.

[0049] Specifically, in this busbar device, the connector base 3 has two types. One type has side clamping holes 3013 on both sides of the main clamping hole. In this type, both ends of the connector base 3 can be clamped and inserted into the supporting conductive rod, thus providing support conductive rods on both sides of the main conductive rod. The other type of connector base 3 has side clamping holes 3013 on only one side of the clamping hole. In this type, only one end of the connector base 3 can be used to clamp and insert the supporting conductive rod, thus providing support conductive rods on only one side of the main conductive rod.

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

[0051] 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 303 is provided inside the connector seat 3. 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 entirely made of insulating material (such as plastic), while the electrical connection piece 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 both ends of the sleeve seat 2 are respectively clamped together with a connector 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 both 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 type of busbar, a passage is provided inside the socket 2 , and the passage inside the socket 2 is for the main conductive rod to pass through.

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

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

[0059] Specifically, to improve the mating stability between the outer sleeve 202 and the inner tube 203, a plurality of sliding plates 2021 are provided on the inner wall of the outer sleeve 202. The sliding plates 2021 are parallel and non-contacting with each other. Sliding grooves 2031 are provided on the inner tube 203, and the sliding plates 2021 and the sliding grooves 2031 slide and fit together tightly. The presence of the sliding plates 2021 and the sliding grooves 2031 improves the mating stability between the inner tube 203 and the outer sleeve 202, ensuring that the probability of jamming is reduced when the inner tube 203 and the outer sleeve 202 slide relative to each other.

[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 on both 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. This can ensure the matching stability of the two adjacent docking blocks 4 and reduce the exposed area of ​​the supporting conductive rods in the air to ensure safety.

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

[0063] The wiring base 1 is specifically used to connect the power line. The entire wiring base 1 is made of insulating material, while the wiring frame is made of conductive material.

[0064] As attached Figure 6 As shown, the docking block 4 is a rectangular parallelepiped docking block 4.

[0065] Attachment 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 strip 401 has four different engaging positions on the bottom 403 of the block. 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. Figure 10 The household docking block 4 shown in FIG 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 piece 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] 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.
