Description

Technical Field

[0001] The utility model relates to the technical field of testing, in particular to a function testing device for a fire-proof current-limiting protector. Background Art

[0002] When the fireproof current limiting protector function test device is in use, the test device is connected to the fireproof current limiting protector through the positive connecting plate and the negative connecting plate to simulate the short circuit, overload, overvoltage, undervoltage, temperature, and leakage conditions in actual operation to test various functions of the fireproof current limiting protector. In the prior art, during the connection process of the function test device, since the test device is relatively large, the connection position of the connecting plate is prone to shaking. In the long run, this will not only cause the connection of the electrode plate to wear, but also cause unstable testing, affecting the test effect. The above problems are solved by setting a fireproof current limiting protector function test device. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a fireproof current limiting protector functional testing device. Through the mutual cooperation of the set test component and the locking component, the electrode sheet can be directly subjected to multiple limit locking during the connection and use process to avoid the occurrence of force shaking and displacement, avoid connection wear, and ensure the stability of the functional test.

[0004] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0014] As a preferred solution of the fire-proof current-limiting protector function test device described in the utility model, the iron block protrusion is fitted into the magnet groove, and the iron block protrusion is adsorbed in the magnet groove.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] 1.

[0017] 2. Based on the beneficial effect 1, by cooperating with each other through the magnet groove, the circular ring and the iron block protrusion, the diameter of the small threaded column can be expanded during use, which is suitable for positioning and locking at different hole positions and improves applicability.

[0018] During specific use, the user fits the first connecting piece and the second connecting piece of the fireproof current limiting protector with the positive connecting piece and the negative connecting piece respectively, and makes the first circular hole fit with the second circular hole accordingly. At this time, the user uses a large threaded column to pass through the first circular hole and the second circular hole, and the internal threaded column and the small threaded column pass through the hole position, and uses a threaded ring to connect with the large threaded column, so that the positive connecting piece and the first connecting piece can be limited and locked.

First, it is tightened by the threaded ring, and positioned by three internal threaded columns and three small threaded columns, which completely avoids deformation and tilting between the positive connecting piece and the first connecting piece when force is applied, thereby ensuring the stability of the connection between the positive connecting piece and the first connecting piece.
