Abstract
Description
Technical Field
[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to a contactor measuring device. Background Technology
[0002] Contactors are widely used in industrial production. Inside a contactor are a moving iron core, a stationary iron core, and a coil. When the coil is energized, the coil generates an electromagnetic force that drives the moving iron core to move toward the stationary iron core, causing the moving iron core to attract the stationary iron core. When the coil is de-energized, the moving iron core moves away from the stationary iron core under the action of the return spring, causing the moving iron core to separate from the stationary iron core.
[0003] In the contactor manufacturing process, the contact gap and contact pressure between the moving and stationary contacts are crucial parameters affecting contactor performance. Monitoring these parameters during production helps analyze the contactor's performance stability and improves its quality.
[0004] In existing technologies, these two parameters are measured manually. When measuring the contact gap, manual measurement using calipers or height gauges is often required; when measuring the contact pressure, manual measurement using a force gauge is often required. Manual measurement is difficult to control in terms of position and accuracy. It is also difficult to reproduce previous measurement results, and the results are highly susceptible to human error. Furthermore, the operation is complex and cannot meet the needs of mass production. Utility Model Content

As another embodiment, the mounting frame 4 can be omitted, and the measurement effect can still be achieved. The driving mechanism 1 is connected to the force measuring mechanism 2.

The force measuring mechanism 2 drives the distance measuring mechanism 3 to move through the co-positioning connector 5.
[0047] This application enables the force measuring mechanism 2 and the distance measuring mechanism 3 to operate synchronously by setting up a co-position connector 5, simultaneously measuring force and distance. This makes it easier to grasp the measurement position, resulting in more accurate measurement results. The operation is simple and can improve the measurement effect.

As another embodiment, the test base 44 may not be provided, and the contactor 6 can be placed directly on the test platform or stabilized by hand, and the testing effect can still be achieved.
[0060] Preferred, such as Figure 2 and Figure 6 As shown, the mounting frame 4 further includes a support plate 45, which is located on the side of the side plate 43 away from the force measuring mechanism 2. The support plate 45 is vertically connected to the base plate 42 and the side plate 43.

[0062] Preferred, such as Figure 7 As shown, the driving component 11 is an operating handle, which allows manual rotation of the screw 14. In this embodiment, the mounting bracket 4 may not have a top plate 41.
[0063] As other embodiments, such as Figure 7 As shown, the force measuring device 21 of the force measuring mechanism 2 of this application can be replaced by the push rod 7. The stroke parameters of the contactor 6 can be tested separately through the push rod 7. The measuring device has a simple structure and lower cost.
[0064] This device is a semi-automatic measuring device, and its working process is as follows:
[0065] The contactor 6 is fixedly mounted on the test socket 44 and connected to the test circuit to monitor whether the contactor 6 is conducting. For example, the test circuit may include a test power supply and an indicator light. The contactor 6 is connected between the test power supply and the indicator light, which is the load terminal. When the contactor 6 is conducting, the indicator light lights up.
[0066] When the device is in its initial position, the force measuring rod of the force gauge 21 is not yet in contact with the moving iron core of the contactor 6, and the reading on the force gauge 21 is 0. First, the drive component 11 drives the screw 14 to rotate. The screw 14, through the moving component 13, drives the force measuring mechanism 2 to move, causing the force measuring rod to move downwards along the first direction X. The force measuring rod contacts and presses against the moving iron core, and the reading on the force gauge 21 is greater than 0. Then, the screw 14 is reversed until the reading on the force gauge 21 is 0, and the digital caliper 31 is zeroed. Next, the screw 14 is rotated to drive the moving iron core until the load end connected to the contactor 6 is detected to be conducting, and the reading on the digital caliper 31 is recorded. First, record the value X1 on the force gauge 21, and then record the value F1. Next, energize the contactor 6 coil to make it engage. At this point, the moving iron core moves until the force gauge 21 reading is 0. Continue driving the screw 14 to rotate, and the test rod moves towards the moving iron core until it contacts it. When the force gauge 21 reading is greater than 0, reverse the screw 14 to return the force gauge 21 reading to 0. At this point, de-energize the contactor 6 coil, record the value X2 on the digital caliper 31, and record the value F2 on the force gauge 21. Where X1 is the contactor 6 opening distance, X2 is the contactor 6 total stroke, F1 is the contactor 6 critical reaction force, and F2 is the contactor 6 total reaction force. Therefore, the overtravel Δ... X =X2-X1, contact pressure F c =F2-F1.
[0067] The total stroke refers to the distance the moving iron core travels from the released state to the engaged state; in terms of measurement, it refers to the distance between the moving iron core and the stationary iron core.
[0068] The open distance refers to the shortest straight-line distance between the moving contact and the stationary contact in the released state of contactor 6; the measurement refers to the distance between the moving contact and the stationary contact.
[0069] Overtravel refers to the distance the moving iron core travels during the engagement process, from the moment the moving contact and the stationary contact just make contact until they are fully engaged; in measurement, overtravel = total travel - opening distance.
[0070] Critical reaction force refers to the reaction force measured by the force gauge 21 at the tail of the moving iron core at the instant when the moving contact and the stationary contact of contactor 6 just make contact;
[0071] Total reaction force refers to the reaction force measured by the force gauge 21 at the tail of the moving iron core when the contactor 6 is fully engaged.

Therefore, they should not be construed as limitations on this utility model.

[0073] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
