Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to an oxime gas testing device and its testing method. Background Technology

[0002] During the curing process, silicone continuously releases oxime gas, which is an alkaline gas. Oxime gas will react chemically with the outer shell of the connector on the junction box, causing the shell to crack. In addition, the copper terminals inside the connector will also oxidize and turn black.

[0003] The existing technology lacks a testing device and method, making it impossible to know the service life of the connector in an oxime environment and the degree of protection it provides to the equipment inside the housing after corrosion. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the problem that the existing technology lacks a testing device and testing method, and thus cannot determine the service life of the connector in an oxime environment, so an oxime testing device and testing method are provided.

[0005] The technical solution adopted by this invention to solve its technical problem is: an oxime gas testing device, including a box, a shelf, and a silicone unit made of silicone. The box has a cavity, the shelf is arranged in the cavity of the box, the silicone unit is coated in the cavity of the box, the shelf is used to place the test piece, and the silicone unit is used to release oxime gas. By placing the silicone unit in the box, the emitted oxime gas reacts with the connector placed in the box to test the service life of the connector.

[0006] To address the issue that the silicone unit is sticky and adheres to the housing, making replacement inconvenient, a further improvement is made by arranging a pad inside the cavity of the housing, on which the silicone unit is placed. Placing the silicone unit on the pad allows it to be easily removed and replaced after testing, once the silicone unit has lost its ability to release oxime gas.

[0007] To address the issue of how to arrange the material of the pad, the pad is further described as being made of plastic film.

[0008] To address the issue of low or incomplete oxime gas release efficiency by the silicone unit, the silicone unit is further provided with channels extending from its surface.

[0009] To address the issue of how to arrange the silicone unit, the silicone unit further includes several silicone layers stacked sequentially from top to bottom.

[0010] To address the issue of how the silicone sheet is arranged, the silicone layer further includes a plurality of interlaced silicone strips with mesh formed between the silicone strips.

[0011] To address the issue of how to arrange the silicone sheets, a further method is proposed that the mesh openings at corresponding positions of two adjacent silicone layers be connected, and several mesh openings be connected to form channels.

[0012] A testing method for an oxime gas testing device, the method using the oxime gas testing device, and comprising the following steps:

[0013] a. Lay the pad on the bottom of the cavity of the box, and apply silicone strips to one side of the pad. The silicone strips are evenly distributed and overlapped to form silicone units.

[0014] b. Place the shelf inside the box, keeping it flat;

[0015] c. Place the prepared connectors on the shelf, distributing them evenly;

[0016] d. Put the cover plate on the box and seal it with silicone.

[0017] e. Set the oven temperature to 85℃ and the time to 72 hours, then place the oven inside to begin testing.

[0018] f. After the test is completed, open the enclosure and inspect the appearance of the connector.

[0019] The beneficial effects of the present invention are as follows: The oxime gas testing device provided by the present invention, by placing a silicone unit in the chamber, emits oxime gas that reacts with the connector placed in the chamber, thereby testing the service life of the connector.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0025] like Figure 1This is a schematic diagram of the structure of the present invention, an oxime gas testing device, including a housing 1, a shelf 2, and a silicone unit 3 made of silicone. The housing 1 has a cavity 11, the shelf 2 is arranged in the cavity 11 of the housing 1, and the silicone unit 3 is coated in the cavity 11 of the housing 1. The shelf 2 is used to place the test piece, and the silicone unit 3 is used to release oxime gas. By placing the silicone unit 3 in the housing 1, the released oxime gas reacts with the connector placed in the housing 1 to test the service life of the connector.

[0026] A pad 4 is arranged inside the cavity 11 of the housing 1, and the silicone unit 3 is placed on the pad 4. Placing the silicone unit 3 on the pad makes it easy to remove and replace the silicone unit 3 after the test is completed, that is, after the silicone unit 3 loses its ability to release oxime gas.

[0027] The pad 4 is made of plastic film.

[0028] The silicone unit 3 has a channel 31 extending from its surface into the interior.

[0029] The silicone unit 3 includes several silicone layers 32 stacked sequentially from top to bottom.

[0030] The silicone layer 32 includes a plurality of interlaced silicone strips 321 and a mesh 311 is formed between the silicone strips 321.

[0031] The mesh 311 at corresponding positions of two adjacent silicone layers 32 are connected, and several mesh 311 are connected to form a channel 31.

[0032] A test method for an oxime gas testing device:

[0033] a. Place the pad 4 on the bottom surface of the cavity 11 of the box 1, and apply silicone strips 321 to one side of the pad 4. The silicone strips 321 are evenly distributed and overlapped to form silicone units 3.

[0034] b. Place the shelf 2 into the box 1, keeping the shelf 2 flat;

[0035] c. Place the prepared connectors on shelf 2, distributing them evenly;

[0036] d. Cover the box 1 with the cover plate and seal it with silicone.

[0037] e. Set the oven temperature to 85℃ and the time to 72 hours. Place chamber 1 inside the oven to begin testing. The silicone is a deoxime-type product, producing methyl ethyl ketone (MEK) oxime. MEK oxime undergoes a hydrolysis reaction, producing alkaline substances. Polycarbonate (PC) is easily hydrolyzed under alkaline conditions, which is the reason silicone causes PC aging. It also contains a large amount of crosslinking agents and reacts to produce small molecules such as methanol. These small molecules can enter the PC polymer, causing swelling and cracking.

[0038] f. After the test is completed, open the housing 1 to inspect the appearance of the connector.

[0039] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
