Description

Technical Field

[0001] The invention relates to the technical field of low-voltage closed busbar systems, and in particular to a four-pole spring pressure type and left-zero adapter. Background Art

[0002] The adapter is a transitional component installed on the busbar system of a circuit breaker, connecting the circuit breaker and the busbar system. Existing adapters feature a busbar clamp that securely connects to the incoming busbar. The clamp consists of a main body and bolts mounted on the clamp body. During assembly, the incoming busbar is inserted into the slots in the clamp body, and the bolts securely connect the main body to the busbar clamp body. Since the bolts require a screwdriver to operate, assembly and disassembly is time-consuming and labor-intensive, reducing assembly and disassembly efficiency. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that it is time-consuming and labor-intensive to fix the incoming busbar and the busbar clamp with bolts, and the disassembly and assembly efficiency is low, thereby providing a four-pole spring pressure type and left-zero adapter that saves time and effort in installing the incoming busbar and the busbar fixing clamp and has high disassembly and assembly efficiency.

[0004] To this end, the present invention provides a four-pole spring pressure type and left zero adapter, including a base, a busbar clamp and a conductive member. The busbar clamp is fixedly installed on the base and is formed with a first slot for inserting an incoming busbar; the conductive member is arranged on the base and has a connecting plate that can extend into the first slot and be elastically pressed with the incoming busbar.

[0005] The conductive member includes a conductive main plate and a connecting plate integrally bent and connected to the conductive main plate. A first biasing member is provided between the connecting plate and the conductive main plate.

[0006] It also includes an adjusting member movably mounted on the busbar clamp, and a second slot for inserting the incoming busbar is formed between the adjusting member and the connecting plate.

[0007] The adjusting member has a first installation position and a second installation position that can be flipped 180 degrees relative to the first installation position in the longitudinal direction, wherein the height of the second slot is different when the adjusting member is in different installation positions.

[0008] The adjusting member has a first stop and a second stop arranged along its diagonal and with different heights; wherein, when in the first installation position, the first stop abuts against the pressure plate at the bottom of the busbar clamp; when in the second installation position, the second stop abuts against the pressure plate.

[0009] The distance between the first stopper and the second stopper is adapted to the size of the pressing plate.

[0010] The adjusting member is connected to the busbar clamp through a positioning structure, and the positioning structure includes a positioning block, a first positioning groove and a second positioning groove. The positioning block is provided on the inner side of the busbar clamp; the first positioning groove is provided on the outer side of the adjusting member and is adjacent to the first stop block. When the adjusting member is in the second installation position, the first positioning groove is adaptively connected to the positioning block; the second positioning groove is provided on the outer side of the adjusting member and is adjacent to the second stop block. When the adjusting member is in the first installation position, the second positioning groove is adaptively connected to the positioning block.

[0011] The positioning block is V-shaped, the positioning groove is V-shaped and matched with the positioning block, and slots for inserting a screwdriver are provided on the front and rear sides of the adjusting member.

[0012] The base is provided with a locking structure which can be locked in cooperation with the incoming busbar.

[0013] The locking structure includes a locking member and a second biasing member. The locking member is installed on the base and has a blocking arm that extends to the opening of the first slot of the busbar clamp and can cooperate with the rear end of the incoming busbar to block; one end of the second biasing member is against the base, and the other end is against the blocking arm. The second biasing member applies a biasing force toward the blocking arm to press it tightly connected with the incoming busbar.

[0014] The technical solution of the present invention has the following advantages:

[0015] 1. The four-pole spring pressure type and left-zero adapter provided by the present invention includes a base, a busbar clamp and a conductive member. The busbar clamp is fixedly installed on the base and is formed with a first slot for inserting the incoming busbar; the conductive member is provided on the base and has a connecting plate that can extend into the first slot and elastically press-fit with the incoming busbar. During assembly, it is only necessary to insert the incoming busbar into the first slot on the busbar clamp. The connecting plate on the conductive member can undergo elastic deformation, so that the incoming busbar and the busbar clamp are tightly connected. Compared with the method in the prior art where the incoming busbar and the busbar clamp body need to be fixedly connected by bolts, this method saves time and effort in assembly and disassembly, and has high efficiency in assembly and disassembly.

[0016] 2. The four-pole spring pressure and left-zero adapter provided by the present invention comprises a conductive body plate and a connecting plate integrally bent and connected to the conductive body plate. A first biasing member is provided between the connecting plate and the conductive body plate. The first biasing member can make the contact between the connecting plate and the incoming busbar tighter and more reliable.

[0017] 3. The four-pole spring pressure and left-zero adapter provided by the present invention has an adjusting member having a first mounting position and a second mounting position that can be flipped 180 degrees longitudinally relative to the first mounting position. The height of the second slot varies when the adjusting member is in different mounting positions. The inventor cleverly changes the height of the second slot by flipping the position of the adjusting member. This enables the busbar clamp to be assembled with incoming busbars of different specifications, expanding its scope of application and reducing inventory costs.

[0018] 4. The four-pole spring pressure type and left-zero adapter provided by the present invention has a spacing between the first stop block and the second stop block that matches the size of the pressure plate, so that the connection between the adjustment block and the pressure plate is tighter, avoiding the change in the relative position of the adjustment member and the busbar clamp due to vibration during transportation. Therefore, when assembling the incoming busbar on site, there is no need to adjust the position of the adjustment member, and the assembly is faster and more convenient.

[0019] 5. The four-pole spring pressure type and left-zero adapter provided by the present invention has an adjusting member connected to the busbar clamp through a positioning structure, and the positioning structure includes a positioning block, a first positioning groove and a second positioning groove, and the positioning block is arranged on the inner side of the busbar clamp; the first positioning groove is arranged on the outer side of the adjusting member and is adjacent to the first stop block. When the adjusting member is in the second installation position, the first positioning groove is adapted to be connected with the positioning block; the second positioning groove is arranged on the outer side of the adjusting member and is adjacent to the second stop block. When the adjusting member is in the first installation position, the second positioning groove is adapted to be connected with the positioning block. The positioning structure can make the connection between the adjusting member and the busbar clamp more firm and prevent the adjusting member from detaching from the busbar clamp; in addition, since only one positioning block needs to be provided, it can be positioned and matched with the first positioning groove and the second positioning groove respectively, so the structure is simple and the production cost is reduced.

[0020] 6. The four-pole spring pressure type and left-zero adapter provided by the present invention has a V-shaped positioning block, a V-shaped positioning groove adapted to the positioning block, and slots for screwdrivers to be inserted on the front and rear sides of the adjusting member. When removing the adjusting member, the user can use a screwdriver to push against the slot, thereby driving the adjusting member to separate from the busbar clamp, making disassembly quick and convenient.

[0021] 7. The four-pole spring pressure type and left zero adapter provided by the present invention has a locking structure including a locking member and a second biasing member. The locking member is installed on the base and has a blocking arm that extends to the opening of the first slot of the busbar clamp and can cooperate with the rear end of the incoming busbar to block; one end of the second biasing member is against the base, and the other end is against the blocking arm. The second biasing member applies a biasing force toward the blocking arm to press it tightly together with the incoming busbar. The locking structure can prevent the incoming busbar from detaching from the busbar clamp, and the second biasing member can make the pressing connection between the blocking arm and the incoming busbar more secure, and the locking member and the second biasing member have the advantage of simple structure.
