Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage electrical appliances, in particular to a leakage switch. Background Art

[0002] The leakage protector, also known as the leakage switch or leakage circuit breaker, is mainly used to protect against leakage faults in the equipment and to protect people from fatal electric shock. It has overload and short-circuit protection functions. It can be used to protect the line or motor from overload and short circuit. It can also be used as an infrequent switching start of the line under normal circumstances.

[0003] The leakage switch is equipped with a test button circuit device to detect whether the leakage protection function of the circuit breaker is normal. The existing test button circuit device solves the problem of induced voltage at the outlet by adding a breakpoint linked to the circuit breaker mechanism, but this increases the difficulty of the production process, makes the assembly more complicated, and reduces the assembly efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a leakage switch to solve the above problems.

[0005] The technical solution of the utility model is implemented as follows: a leakage switch, comprising:

[0006] A housing, wherein a test button is provided on the housing;

[0007] A release, wherein the release is arranged in a housing, and a supporting boss is protruding from an outer wall of the release;

[0008] A side plate, which is arranged in the housing and electrically connected to a terminal of the leakage switch, and is located below the test button;

[0009] A downward pressure spring, the downward pressure spring is vertically arranged on the supporting boss, the downward pressure spring is electrically connected to another terminal of the leakage switch through a conductive mechanism, a contact portion is extended from the upper end of the downward pressure spring, the contact portion extends to between the test button and the side plate, and when the test button is pressed down, the contact portion is driven to bend down and contact and conduct with the side plate;

[0010] Wherein, when the leakage switch is in a closed state, the conductive mechanism is turned on, and when the leakage switch is in an open state, the conductive mechanism is turned off.

[0011] By adopting the above technical solution, when the leakage switch is in the closed state, pressing the test button drives the contact part of the downward pressure spring to bend down and contact and conduct with the side plate, thereby triggering a short circuit trip. By arranging the downward pressure spring and the conductive mechanism separately and supporting them through the supporting boss so that the downward pressure spring and the conductive mechanism always maintain a contact state, the production difficulty of each component is reduced, and the assembly is made more convenient, thereby improving the assembly efficiency.

[0012] The utility model is further configured as follows: the conductive mechanism comprises:

[0013] A conductive rod, which is arranged in the housing and is linked to the opening and closing mechanism of the leakage switch, and is electrically connected to another terminal of the leakage switch;

[0014] A conductive member, one end of which is placed on the supporting boss and in contact with the lower end of the downward pressing spring, the other end of which is arranged close to the conductive rod, and the conductive member is fixed in the housing;

[0015] When the leakage switch performs a closing action, the conductive rod is driven to move toward the conductive member and the conductive member is brought into contact and conducted; when the leakage switch performs an opening action, the conductive rod is driven to move away from the conductive member and the conductive mechanism is disconnected.

[0016] By adopting the above technical solution, the conductive mechanism is in a conducting state only when the leakage switch is closed, and is in a disconnected state when the leakage switch is opened, so the assembly of the conductive parts is very convenient.

[0017] The utility model is further configured as follows: a support rod is protruded from the inner wall of the shell, the downward pressure spring is sleeved on the outer side of the support rod, and the upper end of the downward pressure spring abuts against the upper side of the inner wall of the shell.

[0018] By adopting the above technical solution, the support rod can effectively improve the stability of the downward pressure spring. After the shell is closed, the downward pressure spring can be effectively pressed against the supporting boss to maintain contact with the conductive member, and the assembly is very convenient.

[0019] The utility model is further configured to include:

[0020] A test resistor is connected between the side plate and one terminal of the leakage switch or between the conductive rod and the other terminal of the leakage switch.

[0021] By adopting the above technical solution, when closing the switch, pressing the test button can turn on the test resistor; when opening the switch, pressing the test button cannot turn on the test resistor.

[0022] The utility model is further configured as follows: the support boss is arranged in an L-shaped manner on the outer wall of the release, and the downward pressure spring is arranged on one side of the horizontal support boss.

[0023] By adopting the above technical solution, the supporting boss can not only effectively support the downward pressure spring, but also make the contact between the downward pressure spring and the conductive member more stable.

[0024] The utility model is further configured as follows: the side panels are made of conductive material.

[0025] By adopting the above technical solution, the side plate can be used to fix other components and also be used for conduction. BRIEF DESCRIPTION OF THE DRAWINGS
