Description

Technical Field

[0001] This utility model belongs to the field of LCD screen aging test technology, and in particular relates to a wireless networking system and industrial connection cable for high temperature aging test of LCD screen. Background Technology

[0002] LCD screen aging test is a quality inspection process for liquid crystal displays (LCDs) to simulate the performance changes of LCD screens after long-term use in order to detect potential quality problems in advance.

[0003] After prolonged use, the arrangement of liquid crystal molecules inside an LCD screen may change. Aging tests allow us to observe whether display parameters such as brightness, contrast, and color saturation remain stable. For example, after a certain period of continuous operation, the brightness of an LCD monitor may decrease due to backlight aging or changes in the performance of the liquid crystal molecules. Aging tests help determine whether this brightness decrease is within a reasonable range, thus ensuring the display quality of the product throughout its normal lifespan.

[0004] Considering the performance differences of LCD screens under different temperature environments, high and low temperature aging tests are conducted. The LCD screen is placed in high temperatures and forced to operate continuously under these conditions. Under high temperatures, the performance of the internal electronic components and liquid crystal materials of the LCD screen may change. For example, increased liquid crystal fluidity may lead to blurry images or uneven color distribution.

[0005] Traditionally, the LCD screen is connected to the testing equipment, which then connects to the switch wirelessly. This method limits the number of devices that can be connected and is inefficient. Utility Model Content

[0006] The purpose of this invention is to provide a wireless networking system and industrial connection cable for high-temperature aging testing of LCD screens, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a wireless networking system for high-temperature aging testing of LCD screens, including a PC, a switch, a main router group, a vehicle router group, and aging test equipment. The main router group includes a main router and several secondary routers, and the vehicle router group includes several vehicle routers. The aging test equipment is connected to the LCD screen, and the LCD screen is connected to the vehicle routers via industrial connection cables. A single vehicle router can be connected to multiple aging test devices. The vehicle routers are wirelessly bridged with the main routers or secondary routers. The main routers and secondary routers are wiredly connected to the switch, and the switch is wiredly connected to the PC.

[0008] An industrial connection cable, employing a wireless networking system for high-temperature aging testing of LCD screens as described above, comprises a wire harness and a connector. One end of the wire harness is electrically connected to the connector. A corrugated tube is sleeved on the outside of the wire harness. The connector comprises a body, with a plug at the front end of the body. The plug has a pole at its center, and eight identical female holes are provided inside the pole. Positioning ribs are provided on the outside of the pole. Three guide grooves are provided on the inner wall of the plug, evenly arranged along the axis, for guiding the male end of the testing equipment to be in place and electrically connected to the female holes.

[0009] In a further embodiment of this invention, the outer center of the main body is provided with anti-slip texture.

[0010] In a further embodiment of this invention, a ring of equally spaced raised ribs is provided on the outer side of the main body near one end of the corrugated pipe.

[0012] In a further embodiment of this invention, the wire harness is wrapped with a fireproof layer, a corrosion-resistant layer and an insulation layer in sequence.

[0013] In a further embodiment of this invention, the corrugated pipe is made of plastic.

[0014] The beneficial effects of this utility model are:

[0015] The LCD screen is connected to the aging test equipment, which is composed of a vehicle router as a secondary router. The main router and the secondary router form an upper-layer router with the same name and configuration and are wirelessly bridged with the secondary router. This enables multiple devices to access the network wirelessly within the WIFI coverage area, which is more flexible than wired networking and thus improves the efficiency of testing.

The main router group 6 includes a main router 60 and several secondary routers 61. The vehicle router group 7 includes several vehicle routers 70. The aging test device 8 is connected to the LCD screen, and the LCD screen is connected to the vehicle routers 70 via industrial connection cables. A single vehicle router 70 can connect to multiple aging test devices 8. The vehicle routers 70 are wirelessly bridged with the main router 60 or secondary routers 61. The main router 60 and secondary routers 61 are wiredly connected to the switch 5, and the switch 5 is wiredly connected to the PC 4. The LCD screen is connected to the aging test device 8, and the vehicle router group 7 forms a secondary router. The main router 60 and secondary routers 61 form an upper-layer router with the same name and configuration, which is wirelessly bridged with the secondary router. This enables multiple devices to access the network wirelessly within the WIFI coverage area, offering greater flexibility compared to wired networking and thus improving testing efficiency.

[0025] In another embodiment, an industrial connection cable is provided, applied to the above-described solution, see reference. Figure 2 and Figure 3 The specific industrial automation connection line includes a wire harness 1 and a connector 2. One end of the wire harness 1 is electrically connected to the connector 2. In this embodiment, the other end of 1 is not shown. The other end is connected to the vehicle router 70. Information data transmission is realized through the connection between the connector 2 and the male terminal on the aging test equipment 8.

[0026] The connector 2 includes a body 20, with a plug 21 at the front end. The plug 21 has a pole post 22 at its center, and eight identical female holes 23 are provided inside the pole post 22. Positioning ribs 24 are provided on the outer side of the pole post 22. Three guide grooves 25 are provided on the inner wall of the plug 21, which are evenly arranged along the axis. The male end of the test equipment is aligned with the plug 21 on the connector 2 and inserted. After being aligned in place under the guidance of the guide grooves 25, it communicates with the eight female holes 23 on the pole post 22, making the connection stable, reliable and convenient.

[0027] Preferably, the connector 2 is made of brass, which has good conductivity and does not rust, thus improving the stability of data transmission.

[0028] The main body 20 has anti-slip texture 26 around its center, and a ring of equally spaced raised ribs 27 is provided around the main body 20 near the end of the corrugated tube 3. The anti-slip texture 26 and raised ribs 27 increase the friction with fingers, making it easier to connect or pull out.

[0029] The wire harness 1 is wrapped with a fireproof layer, a corrosion-resistant layer and an insulation layer in sequence. When excessive heat is generated under load, it has good heat resistance and corrosion resistance. The insulation layer avoids the risk of electric shock and can withstand high temperature tests.
