Description

Technical Field

[0001] This article proposes the technical field of a conductive spring support shaft, specifically relating to a conductive spring support shaft fixed by a tenon. Background Art

[0002] With the development of urban civil power supply and industrial power supply, the load of power facilities has gradually increased, and it is necessary to equip bus duct plug-in boxes that can provide large current and reliable connection to ensure the safe operation of the power supply system.

[0003] In order to better adapt to the plug-in box, a straight-plug-in box is usually used to directly connect with the center-split bus duct. In the existing center-split bus duct, the opening in the middle of the center-split bus duct is very wide. Although this improves the convenience of bus duct installation and plug-in box installation, the wide middle seam will cause the operator's hands or other tools to penetrate into it, thereby creating a safety hazard. Therefore, a narrow-slit center-split busbar is now used to ensure safety.

[0004] In order to adapt to this narrow-slot bus duct, a special plug-in type plug-in box is required. After the plug-in board is inserted into the bus duct, the conductive piece on the plug-in board needs to be extended using an independent expansion structure and connected to the conductor busbar in the bus duct, so that the plug-in box and the bus duct can be connected to each other.

[0005] The prior art CN206076887U discloses a busbar duct plug-in board, comprising a box body, a mounting base, and a plug-in board; the box body comprises a box shell and a box door, a circuit breaker is mounted on the upper right side of the rear mainboard of the box shell, three sockets are mounted on the right side of the bottom plate of the box shell, the mounting base is fixed to the box body, the plug-in board is vertically arranged in the middle of the horizontal plate of the L-shaped mounting plate and extends outward through the concave area, and contact pieces are affixed to the left and right planes of the plug-in board; a driving link mechanism and a locking mechanism are mounted on the mounting base, the driving link mechanism comprises a flip shaft, a swing rod, a slider, and a locking knob, and the locking mechanism is a safety screw. The advantages of the present invention are: a busbar duct plug-in box adopts a mechanical connection method of connecting rod clamping and locking, which not only ensures effective contact between the contact piece and the copper busbar, but also better locks and fixes the plug-in device to the busbar, thereby improving safety and facilitating installation and maintenance.

[0006] However, the ordinary pivot bracket can only lift the conductive spring upward from the bottom, and cannot provide a good support limit for the conductive spring. Secondly, the ordinary support rod can only support the conductive piece, and cannot assist in the connection and fixation between the plug-in box and the bus duct, which wastes the effect of the rotation locking force. Summary of the Invention

[0007] This article proposes a support shaft for a conductive spring piece fixed by a tenon, wherein the support shaft and the conductive spring piece are both arranged in the plug-in board of the plug-in box, and the support shaft is arranged below the conductive spring piece. The support shaft includes a rotating seat, a limit seat, a main shaft, a busbar support rod, a lower push rod and an upper push rod. A limit seat is provided above the rotating seat, a main shaft is provided above the limit seat, a busbar support rod is provided below the outer side of the main shaft, a lower push rod is provided above the busbar support rod, and an upper push rod is provided above the lower push rod. The lower push rod, upper push rod and busbar support rod are all flush with each other. By setting a special busbar support rod, the connection between the plug-in box and the busbar trough can be more stable, and it is more convenient to install and disassemble the plug-in box. At the same time, the push rod also has independent fixation for the expansion and contraction of the conductive spring piece, ensuring the stability of the overall plug-in and convenience during installation.

[0008] The shaft seat is in the shape of a cylindrical block, and a driving hole is provided through the outer side of the shaft seat. A limit seat is provided at the top center of the shaft seat. The limit seat is in the shape of a cylinder, and the diameter of the limit seat is smaller than the diameter of the shaft seat. A main shaft is provided at the excessive bevel of the top of the limit seat. The main shaft is in the shape of a cylinder, and the diameter of the main shaft is smaller than the diameter of the limit seat. The outer sides of the main shaft are connected to the busbar support rod, the lower push rod and the upper push rod. The main shaft is driven to rotate through the shaft seat to output power, and the limit seat supports the shaft to be inserted into the socket board so as to be locked with the limit lock at the entrance.

[0009] The busbar support rod is in the shape of a strip rod. Both ends of the busbar support rod are provided with arc transitions. The middle of the busbar support rod is provided with a main shaft through hole. The top surface of the busbar support rod is a flat surface. The bottom surface of the busbar support rod is provided with clockwise beveled edges on both sides based on the main shaft through hole. The busbar support rod can be erected at the same time as the main shaft rotates, so that the top surface of the busbar support rod can be connected to the inner edge of the busbar duct, thereby supporting the entire busbar duct.

[0010] The lower rod and the upper rod are of equal shape, and the lower rod and the upper rod are mirror images of each other, and the shape of the lower rod and the upper rod are rectangular blocks, and a semi-circular arc main shaft groove is provided on one side of the rectangular block, and an arc supporting edge is provided on the other side of the rectangular block. The upper and lower sides of the arc supporting edge are provided with arc side plates, and the center of the arc supporting edge is provided with a fixing groove. The semi-circular arc main shaft groove of the lower rod is connected to the outer side of the main shaft, the lower rod faces the busbar support rod, and the lower rod is aligned with the left end of the busbar support rod. The semi-circular arc main shaft groove is connected to the outer side of the main shaft, the upper rod faces the busbar support rod, and the upper rod is aligned with the right end of the busbar support rod. The arc supporting edge and the fixing groove on the rod have independent fixation for the expansion and contraction of the conductive spring sheet, ensuring stability during overall insertion and convenience during installation, and the setting flush with the busbar support rod can make the busbar support rod, the lower rod and the upper rod rotate together on a common plane.

[0011] The driving hole is in the shape of a circular hole and is arranged on the rotating shaft seat at an oblique angle to the busbar support rod. The oblique angle setting of the driving hole can ensure that the driving hole will not be completely horizontal when rotated ninety degrees, so that the driving rod that drives the driving hole has sufficient room to move.

[0012] Beneficial effects:

[0013] By setting up a special busbar support rod, the connection between the plug-in box and the busbar duct can be more stable, and it is more convenient to install and disassemble the plug-in box. At the same time, the top rod also independently fixes the expansion and contraction of the conductive spring, ensuring the stability of the overall plug-in and convenience during installation.

[0014] The main shaft is driven to rotate by the rotating shaft seat to output power, while the limit seat supports the rotating shaft to be inserted into the plug-in board so as to achieve limit locking with the entrance.

[0015] The arc-shaped support edge and fixed slot on the ejector rod independently fix the expansion and contraction of the conductive spring, ensuring the stability of the overall plug-in and the convenience of installation. The setting flush with the busbar support rod enables the busbar support rod, the lower ejector rod and the upper ejector rod to rotate together on the same plane.

[0016] The bevel setting of the driving hole can ensure that the driving hole will not be completely horizontal when it is rotated ninety degrees, so that the driving rod that drives the driving hole has enough movable space to drive. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Implementation examples;

[0026] First, insert the plug-in board in the plug-in box into the bus duct, and drive the rotating shaft through the drive shaft on the plug-in box.

[0027] The driving shaft drives the rotating seat 1 to rotate, and the rotating seat 1 rotates together with the limit seat 2 and the main shaft 3. After the main shaft 3 rotates ninety degrees, the busbar support rod 4, the lower push rod 5 and the upper push rod 6 are all vertical, and the conductive spring piece on the inner side of the plug-in board inserted in the busbar is lifted up by the lower push rod 5 and the upper push rod 6. The arc-shaped side plates on the upper and lower sides of the lower push rod 5 and the upper push rod 6 are connected to the two sides of the conductive spring piece to limit and fix the conductive spring piece. After the busbar support rod 4 is horizontal, the top surface of the busbar support rod 4 will be connected to the inner edge of the busbar duct, so that the busbar support rod 4 can better fix and lock the busbar duct and the plug-in box.

[0028] When the plug-in is to be disassembled, the rotating seat 1 drives the main shaft 3 to rotate together. The rotation of the main shaft 3 drives the busbar support rod 4, the lower push rod 5 and the upper push rod 6 to all be leveled. At this time, the conductive spring piece falls through the arc-shaped support edge of the push rod, and the arc-shaped side plates on the upper and lower sides of the push rod will also move forward to no longer limit and fix the conductive spring piece. After it is completely dropped, the fixed slot in the middle of the arc-shaped support edge will be fixed with the fixed hook under the conductive spring piece, so that the conductive spring piece has an upper and lower fixing force even after it is completely leveled. After the busbar support rod 4 is leveled, the support of the plug-in box and the busbar duct is cancelled, and the plug-in box can be easily taken out of the busbar duct.
