Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of circuit breaker, in particular to a circuit breaker adapter which reduces the wiring difficulty of the circuit breaker. BACKGROUND

[0002] The circuit breaker is an important part of the power distribution electrical appliance, mainly used in industrial low-voltage power system to connect and disconnect the current in the power grid circuit and protect the line and power supply equipment from the damage of overload, under-voltage, short circuit, single-phase grounding and other faults.

[0003] The circuit breaker adapter is mainly used in the power distribution cabinet to provide a mounting platform for the circuit breaker and is used in close combination with the circuit breaker, mainly for the transfer and transmission of electric energy. In the prior art, the transfer and transmission of electric energy in the power distribution cabinet are usually achieved by fixedly connecting the copper bar with the circuit breaker by bolts. When the circuit breaker is installed, the electrical connection between the incoming line and the outgoing line is achieved by using bolts, so that the installation efficiency is low when the circuit breaker is initially installed or is replaced in the later period. When the adapter is used, the electrical connection between the circuit breaker and the adapter is achieved by one-time clamping or plugging, which can realize quick installation or replacement, and the efficiency of on-site maintenance and replacement is greatly improved.

[0004] Chinese patent ZL201820304904.7 discloses a circuit breaker adapter, which comprises a shell, a first wiring structure and a second wiring structure, a busbar, a wiring board and a conductive plate. The shell is arranged at the bottom of the circuit breaker and has a receiving cavity. The first wiring structure and the second wiring structure are installed on the shell and correspondingly connected to the first wiring end and the second wiring end of the circuit breaker. The busbar is installed in the receiving cavity and connected to the second wiring structure at one end and to the hook structure of the external busbar at the other end. The wiring board is arranged on the side of the shell corresponding to the second wiring end and used for connecting the wire. The conductive plate is installed in the receiving cavity and connected to the wiring board at one end and to the first wiring structure at the other end. The adapter can enable the operator to directly perform the assembly of the wire from the upper end of the circuit breaker, so that the operator's visual line is not easily blocked, the assembly error or loose connection is avoided, the assembly is convenient, and the wire does not need to bypass the circuit breaker due to the connection of the outgoing line end, thereby avoiding the hidden danger. However, the adapter still has the following defects:

[0005] (1) A large operating force is required for installation and disassembly, increasing the difficulty of use.

[0006] (2) The incoming line and the outgoing line are not associated, which can easily lead to wiring operation under live conditions and cause safety accidents.

[0007] (3) The wiring state of the adapter is irrelevant to the on-off state of the circuit breaker, which can easily lead to wiring operation under live conditions and cause safety accidents. SUMMARY

[0008] The present application aims at the defects of the existing circuit breaker adapter, and provides a circuit breaker adapter which reduces the operating force of the incoming line and outgoing line connection through the lever principle, and associates the incoming line and outgoing line and the on-off state of the circuit breaker to avoid the wiring operation under the live condition and improve the safety performance of the whole device.

An input insulating cap 5a03 is installed on the input pin 5a02 to prevent the input pin 5a02 from being exposed while energized. The input wiring assembly 8 is a copper busbar. A spring 5c01 is installed at the front end of the horizontal input connector 5c to increase the insertion and extraction force. As shown in the attached figure. Figure 2 and 3 As shown, the two ends of the feed cable linkage shaft 3b pass through the feed cable linkage shaft mounting holes 5a01 on the feed cable sliding housing 5a, located as shown in the attached figure. Figure 5 The cable inlet is located in the horizontal cable inlet oblong hole 104 on the cable inlet end of the base 1 shown, and can slide within the horizontal cable inlet oblong hole 104. The outer side of the cable inlet sliding housing 5a is connected to the interlocking mechanism 11 via a cable inlet stepped screw 5d.

(See attached...) Figure 4a As shown in 4b and 4c, the outgoing end sliding adapter assembly 6 includes an outgoing sliding housing 6a, which can be connected as shown in the attached diagram. Figure 5The shown outlet slide slot 106 of the base 1, the vertical outlet connector 6b is installed in the inner cavity of the outlet slide shell 6a corresponding to the outlet wiring assembly 9, in this embodiment, the outlet wiring assembly 9 is composed of a wiring support and a wiring column, the outlet wiring assembly 9 is fixed on the base 1 by riveting or bolt, the horizontal outlet connector 6c is fixed on the upper end of the vertical outlet connector 6b corresponding to the output wiring assembly 10 by fastener two 6d, in this embodiment, the horizontal outlet connector 6c is fixed on the upper end of the vertical outlet connector 6b by fastener two 6d, and then the whole is fixed in the inner cavity of the outlet slide shell 6a by outlet pin 6a02, the outlet pin 6a02 passes through the outlet groove 6b01 on the vertical outlet connector 6b to fix the vertical outlet connector 6b and avoid being pulled out, the outlet pin 6a02 is provided with an outlet insulation cap 6a03 to prevent the outlet pin 6a02 from being exposed to electricity, the output wiring assembly 10 is a copper wiring, and the front end of the horizontal outlet connector 6c is provided with spring two 6c01 to increase the plug force. As shown in the accompanying Figure 2 and 3 As shown, the both ends of the outlet linkage shaft 4b pass through the outlet linkage shaft mounting hole 6a01 on the outlet slide shell 6a and are located in and can slide in the horizontal outlet waist-shaped hole 107 on the outlet end of the base 1, the outer side of the outlet handle 4 is provided with a limiting protrusion 4c corresponding to the interlocking mechanism 11. The outlet step screw 11b passes through the horizontal outlet interlocking waist-shaped hole 108 on the outlet end of the base 1 and can slide in the horizontal outlet interlocking waist-shaped hole 108.

[0055] As shown in the accompanying Figure 2 and 3As shown, the interlocking mechanism 11 includes a slide rod 11a. An inlet step screw 5d passes through an inlet end connection hole 11a01 on one end of the slide rod 11a and is locked in an inlet step screw locking hole 5a04 on the inlet sliding housing 5a. The inlet step screw 5d is installed in a horizontal inlet interlocking waist-shaped hole 105 at the inlet end of the base 1 and can slide in the horizontal interlocking waist-shaped hole 105. An outlet step screw 11b is locked in an outlet step screw locking hole 1104 on the slide rod 11a. The outlet step screw locking hole 1104 is located on the slide rod 11a near the outlet end. The outlet step screw 11b is located in a horizontal outlet interlocking waist-shaped hole 108 at the outlet end of the base 1 and can slide in the horizontal outlet interlocking waist-shaped hole 108. The other end of the slide rod 11a is provided with a limiting step 11a02, which corresponds to the limiting protrusion 4c provided on the outer side of the outlet handle 4, so that the slide rod 11a and the outlet handle 4 can be interlocked. In this embodiment, there are two inlet connection holes 11a01 arranged vertically. The slide rod 11a is symmetrically placed on both sides of the circuit breaker 2, so the upper hole is used on one side and the lower hole is used on the other side.

[0056] As attached Figure 6a As shown in 6b, 6c, and 6d, the locking mechanism 12 includes a first connecting rod 12a, the bottom end of which is connected to the drive shaft 12b. The upper end of the first connecting rod 12a is provided with a locking pin group 12c, which is located in the locking hole 11a03 on the slide rod 11a. The drive shaft 12b is connected to the rotating shaft 13 inside the circuit breaker through a second connecting rod 12d. The rotating shaft 13 has different positions when the circuit breaker is open and closed. The locking hole 11a03 includes a horizontal locking hole 11a0301 and an arc-shaped limiting hole 11a0302 at the inlet end. The locking pin group 12c includes a locking pin 12c01 and a locking pin 2 12c02. During the rotation of the connecting rod 12a driven by the circuit breaker shaft 13, the inner side of the locking pin 12c01 is located in the corresponding horizontal locking hole 11a0301, the locking pin 2 12c02 is located in the corresponding arc-shaped limiting hole 11a0302, and the outer side of the locking pin 12c01 is located in the limiting hole 1a on the base 1.

[0057] The lower end of the first connecting rod 12a is fitted onto the drive shaft 12b through the connecting rod waist-shaped hole 12a01. Both ends of the drive shaft 12b are limited by the limiting step screws 12e. The second connecting rod 12d is mounted on the base 1 through the connecting rod shaft 12f mounted on the base 1. The lower end is pivotally mounted on the drive shaft 12b. The upper end of the second connecting rod 12d is clamped onto the circuit breaker shaft 13.

[0058] The working principle of the present embodiment is that when the circuit breaker is in the closed state, the circuit breaker rotating shaft 13 drives the connecting rod 2 12d to rotate the connecting rod 1 12a, which makes the locking pin 1 12c01 and the locking pin 2 12c02 locate in the corresponding horizontal locking hole 1 11a0301 and the arc-shaped limiting hole 1 11a0302, thereby limiting the stroke of the sliding rod 11a and preventing the incoming line handle 3 from pulling the incoming line end sliding adapter assembly 5. The lower end surface 4d of the outgoing line handle 4 is blocked by the limiting surface 11a0201 of the limiting step 11a02 and cannot be rotated outward. As shown in the accompanying Figure 7 .

[0059] When the circuit breaker is in the open state, the circuit breaker rotating shaft 13 drives the connecting rod 2 12d to rotate the connecting rod 1 12a, which makes the locking pin 1 12c01 and the locking pin 2 12c02 locate in the horizontal locking hole 1 11a0301, as shown in the accompanying Figure 8 , the sliding rod 11a can move back and forth. At this time, the incoming line handle 3 can pull the incoming line end sliding adapter assembly 5 to disconnect from the incoming line connection assembly 7 and the input connection assembly 8, while the lower end surface 4d of the outgoing line handle 4 is blocked by the limiting surface 11a0201 of the limiting step 11a02 and cannot be rotated outward. As shown in the accompanying Figure 9 , only when the incoming line handle 3 pulls the incoming line end sliding adapter assembly 5 to completely open, the limiting surface 11a0201 of the limiting step 11a02 does not block the lower end surface 4d of the outgoing line handle 4, the outgoing line handle 4 can be rotated outward to pull the outgoing line end sliding adapter assembly 6 to disconnect from the outgoing line connection assembly 9 and the output connection assembly 10. In this state, the sliding rod 11a acts on the connecting rod 1 12a through the locking hole 1 11a03, the connecting rod 1 12a is locked and cannot be rotated, thereby locking the circuit breaker and preventing it from being closed. As shown in the accompanying Figure 10 , when the outgoing line handle 4 pulls the outgoing line end sliding adapter assembly 6 to completely open, the limiting protrusion 4c blocks the right side surface 11a0202 of the limiting step 11a02, so the sliding rod cannot move to the outgoing line end. Therefore, at this time, the incoming line handle 3 cannot push the incoming line end sliding adapter assembly 5 to connect with the incoming line connection assembly 7 and the input connection assembly 8.
