【Technical field】

The utility model 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.

【Content of invention】

Therefore, the purpose of this utility model is to provide a network interface unit test device, which solves the troublesome problem of disassembly if the crystal head fails the shaking test after the network interface unit is installed in electronic products.

In order to achieve the above object, the utility model provides a network interface unit testing device, the network interface unit has an inlet and an outlet, and both the inlet and the outlet have at least four signal pins, and the testing device includes:

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.

Optionally, the network interface monomer is an RJ11 interface monomer.

Compared with the prior art, using the network interface monomer testing device of the present utility model, when testing, the crystal head of the network cable is inserted into the entrance of the network interface monomer, and the connector is inserted into the outlet of the network interface monomer , shake the crystal head, if the display of the display unit remains unchanged, the unit test of the network interface is passed; if the display of the display unit changes (for example, the light-emitting diode becomes dark or not bright), the unit test of the network interface 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.
