[0059] The cable plug waterproof test equipment provided by the embodiment is used for evaluating the waterproof level of two cable plugs (referred to as a first cable plug and a second cable plug respectively) of a transmission cable.

[0060] Then, the air tightness of the first plug test slot 201 and the second plug test slot 401 is detected by starting the air tightness detection assembly.

[0061] If there is no micro crack in the first cable plug and the second cable plug, the first plug test slot 201 and the second plug test slot 401 are completely closed, and the internal air pressure of the plug test slot reaches a preset value within a preset time; otherwise, if there is a micro crack in the first cable plug or the second cable plug, the first plug test slot 201 or the second plug test slot 401 is connected to the external space of the insulation part through the micro crack of the corresponding cable plug, and accordingly, the internal air pressure cannot reach the preset value within the preset time.

[0062] Therefore, the air pressure parameter of the first plug test slot 201 or the second plug test slot 401 at a specified time is obtained, and whether the first cable plug and / or the second cable plug has a micro crack connected to the outside of the insulation part is determined, and then the waterproof level of the first cable plug and / or the second cable plug is evaluated.

[0063] Therefore, the cable plug waterproof test equipment provided by the embodiment is used for realizing the air tightness test of the cable plug, so as to evaluate the waterproof level of the cable plug.

[0064] In the embodiment, the first compression assembly 3 comprises a fixed base 301, a rotating pressing plate 302, a compression torsional spring, a first hand piece 303 and a silica gel pad 304.

[0065] The fixed base 301 is located at the side of the first plug jig 2. One end of the rotating pressure plate 302 is hinged to the fixed base 301 through a rotating shaft, and the other end extends above the first plug test slot 201. The compression torsion spring is sleeved on the rotating shaft, which is used to drive the other end of the rotating pressure plate 302 to rotate towards the first plug jig 2, so as to compress the first cable plug. One end of the first hand-breaking piece 303 is fixed to the rotating pressure plate 302, and the other end extends upward and away from the first plug jig 2. The silica gel pad 304 is fixed to the bottom of the other end of the rotating pressure plate 302.

[0066] Generally, the compression torsion spring drives the other end of the rotating pressure plate 302 to rotate towards the first plug jig 2, so that the silica gel pad 304 compresses the first cable plug; when the first cable plug needs to be taken out, the other end of the first hand-breaking piece 303 needs to be pressed downward, the first hand-breaking piece 303 overcomes the elastic action of the compression torsion spring, drives the rotating pressure plate 302 to rotate upward to release the first cable plug, and then the first cable plug can be taken out.

[0067] In this embodiment, the second compression assembly 5 includes a vertical stand plate 501, a fixed seat 502, a second hand-breaking piece 503, a transfer plate 504, a vertical sliding rod 505, and a silica gel pressing block 506.

[0068] The vertical stand plate 501 is fixed to the side of the second plug jig 4. The fixed seat 502 is fixed to the upper end of the vertical stand plate 501. The middle part of the second hand-breaking piece 503 is hinged to the upper end of the fixed seat 502. One end of the transfer plate 504 is hinged to one end of the second hand-breaking piece 503. The upper end of the vertical sliding rod 505 is hinged to the transfer plate 504, and the lower end extends above the second plug jig 4 after sliding through the fixed seat 502. The silica gel pressing block 506 is fixed to the bottom of the vertical sliding rod 505.

[0069] Rotating the second hand-breaking piece 503 downward can drive the vertical sliding rod 505 to move downward with the silica gel pressing block 506 and compress the second cable plug; conversely, rotating the second hand-breaking piece 503 upward can drive the vertical sliding rod 505 to move upward with the silica gel pressing block 506 and release the second cable plug.

[0070] Both the first plug jig 2 and the second plug jig 4 can be detachably mounted on the bottom plate 1. Specifically, both the first plug jig 2 and the second plug jig 4 are fastened and connected to the bottom plate 1 through fastening bolts.

[0071] In this embodiment, the air tightness detection assembly includes a timer, an inflation pump or a vacuum pump, a first air pipe 601 connecting the inflation port of the inflation pump to the first air hole, a first pressure gauge connected to the first air pipe 601, a second air pipe 602 connecting the inflation port of the inflation pump to the second air hole, and a second pressure gauge connected to the second air pipe 602. The timer starts timing when the inflation pump or the vacuum pump is started. After a specified time, the pressure data detected by the first pressure gauge and the second pressure gauge are obtained, and it can be determined whether there is a tiny crack.

[0072] In summary, the cable plug waterproof test equipment provided by the embodiment has the following advantages:

[0073] ① Precise detection: The air tightness detection assembly can accurately detect whether there is a tiny crack inside the cable plug, thereby evaluating its waterproof level.

[0074] ② Double plug simultaneous test: The equipment can test two cable plugs at the same time, improving test efficiency and reducing test time.

[0075] ③ Compression assembly design: The design of the first compression assembly 3 and the second compression assembly 5 ensures that the cable plug can be firmly and uniformly compressed during the test, ensuring the accuracy of the test.

[0076] ④ Easy to operate: The design of the rotating pressure plate 302 and the hand bending piece makes it easy for the operator to load and unload the cable plug, improving the operation convenience.

[0077] ⑤ Protect the cable plug: The use of the silica gel pad 304 and the silica gel compression block 506 avoids damage to the cable plug during compression, protecting the surface of the plug.

[0078] ⑥ Modular design: The first plug jig 2 and the second plug jig 4 can be detached and installed on the bottom plate 1, facilitating maintenance and replacement.

[0079] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the present application, they do not limit the patent protection scope of the present application. Any equivalent structure or equivalent process substitution or modification based on the essential concept of the present application, using the content described in the specification and drawings, and directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are all included in the patent protection scope of the present application.
