Description

Technical Field

[0001] The utility model relates to the technical field of air switch testing, in particular to an air switch testing fixture. Background Art

[0002] Air switch, also known as air circuit breaker, is a type of circuit breaker. It is a switch that automatically disconnects as long as the current in the circuit exceeds the rated current; air switch is a very important electrical appliance in low-voltage power distribution network and electric traction system, which integrates control and multiple protection functions; in addition to completing contact and disconnection of circuits, it can also protect circuits or electrical equipment from short circuits, severe overloads and undervoltages, and can also be used to start motors infrequently. Since air switches are widely used, they are produced in large quantities, so it is also necessary to speed up the testing of air switches.

[0003] For example, a Chinese utility model patent with announcement number CN217181153U discloses a test device for an air switch. Although the above-mentioned prior art solves the problem of poor safety, shortens the wiring time, and improves the test efficiency and safety, air switches are widely used, so a large number of them are produced at one time, and each air switch needs to be tested. The above-mentioned prior art can only test one air switch at a time, and the air switch needs to be fixed and installed, which leads to a longer test time for an air switch. If a large number of air switches need to be tested, the efficiency will be greatly affected, which will affect the subsequent production. Therefore, it is necessary to design an air switch test fixture that can test multiple air switches at the same time. Utility Model Content

[0004] In order to solve the technical problem that the prior art can only perform installation and fixing test on one air switch at a time, which affects efficiency, the utility model provides an air switch test fixture.

[0005] The utility model is implemented by the following technical scheme: an air switch test fixture, including a test frame, wherein a plurality of air switches waiting to be tested are arranged inside the test frame, a power connection component for allowing adjacent air switches to be powered on for testing is arranged on each of the air switches, a placement component for facilitating the placement and testing of a plurality of air switches and for uniformly collecting the air switches that have completed the test is arranged at the bottom of the test frame, and synchronization components for allowing a plurality of power connection components to be disconnected from adjacent air switches at the same time are arranged on both sides of the test frame.

[0006] Through the above technical solution, multiple air switches are placed in the corresponding positions of the test frame, and the power connection component will automatically insert one end of the wire into the wiring slot of the air switch for testing.

[0007] As a further improvement of the above scheme, sliding grooves are provided on both sides of the test frame, and the power connection component includes a first wire arranged on one side of the air switch, a second wire arranged on the other side of the air switch, and a sliding block slidably sleeved on the first wire and the second wire, and the two sliding blocks are slidably matched with adjacent sliding grooves.

[0008] Through the above technical solution, the sliding block cooperates with the first wire and the second wire to adjust the position of the wires, which is convenient for testing air switches of different models.

[0009] As a further improvement of the above solution, one end of the first wire and the second wire is fixedly sleeved with a circular limit plate, and the outer surface of the first wire and the second wire is sleeved with a push spring with one end fixedly installed with the adjacent limit plate and the other end fixedly installed with the adjacent sliding block.

[0010] Through the above technical solution, the push spring pushes the limit plate, thereby inserting one end of the wire into the wiring slot.

[0011] As a further improvement of the above-mentioned scheme, the placement assembly includes a placement plate slidably arranged on one side of the test frame, sliding bars fixedly installed on both sides of the test frame, and moving bars fixedly installed on both sides of the placement plate, and one side of the two moving bars is provided with a moving groove that is compatible with the adjacent sliding bars.

[0012] Through the above technical solution, the air switches are placed on the placement board, and when the test is completed, the placement board can be slid to remove all the air switches.

[0013] As a further improvement of the above scheme, the synchronization assembly includes a synchronization plate arranged on one side of the test frame and a plurality of synchronization rings arranged on one side of the synchronization plate, the synchronization plate is slidably mounted on a plurality of adjacent first wires, and the plurality of synchronization rings are fixedly mounted on the adjacent first wires.

[0014] Through the above technical solution, pulling the synchronization plate can allow the synchronization ring to drive the wires to move synchronously.

[0015] As a further improvement of the above solution, one side of the plurality of limit plates is in contact with the adjacent air switch, and one end of the plurality of first wires and the plurality of second wires extends into the wiring slot of the adjacent air switch.

[0016] Through the above technical solution, the limit plate will limit the length of the wire inserted into the wiring slot to avoid excessive length affecting the test.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model arranges a power connection component, a placement component and a synchronization component. When testing multiple air switches of the same model, the multiple air switches are placed on the placement component, and the power connection component automatically inserts the wires into the wiring slots of adjacent air switches. After the power-on test is completed, the placement component is slid and the synchronization component is pulled to separate the power connection component from the air switch. Without the support of the placement component, the air switch that has completed the test will fall and be collected. In this way, multiple air switches can be tested and collected at the same time, which improves the test efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
