【Technical field】

The invention relates to a test device, in particular to a network interface unit test device.

【Background technique】

At present, many electronic products will have network interfaces (RJ45, RJ11), such as desktop computers and notebook computers. For the RJ45 interface, it has eight pins: white orange, orange, white green, blue, white blue, green, white brown, and brown, and we usually use orange, blue, green, and brown. Four pins to transmit signals. Of course, RJ11 also uses four pins to transmit signals.

For mobile devices such as laptops, it is usually necessary to move when connecting the network cable, so when the network interface is moved, the network cable will not shake and cause poor contact. For this requirement, the corresponding network interface monomer needs to verify whether the shaking of the crystal head of the network cable will affect the signal transmission. At present, it can only be tested by measuring from the appearance size or installing the network interface monomer on the electronic product.

However, the measurement of the appearance size is not reliable, and for installing the network interface monomer on the electronic product, if it is unqualified, it needs to be disassembled, which is troublesome and harmful to the electronic product.

In view of this, it is necessary to develop a network interface unit test device to solve the above problems.

Optionally, the DC power supply voltage is 3V.

Optionally, the network interface monomer is an RJ45 interface monomer.

Optionally, the four signal lines are respectively orange, blue, green, and brown signal lines of the network cable.

Compared with the prior art, using the network interface monomer testing device of the present invention, when testing, insert the crystal head of the network cable into the entrance of the network interface monomer, insert the connector into the outlet of the network interface monomer, Shake the crystal head, if the display of the display unit remains unchanged, the network interface unit test is passed; if the display unit display changes (for example, the light-emitting diode becomes dark or not bright), the network interface unit test fails. Since the above-mentioned shaking test does not need to install the network interface unit on the electronic product, there is no need to disassemble the test if the test fails.
