technical field

The utility model relates to the field of server cabinet plug-in detection, in particular to a PDU plug-in test fixture.

Background technique

PDU (PowerDistributionUnit, power distribution unit), which is what we often call power distribution strips for cabinets, PDU is a product designed to provide power distribution for cabinet-mounted electrical equipment, with different functions, installation methods and different plug positions Combining multiple series of specifications can provide suitable rack-mounted power distribution solutions for different power environments. The application of PDU can make the power distribution in the cabinet more orderly, reliable, safe, professional and beautiful, and make the maintenance of the power supply in the cabinet more convenient and reliable.

The PDU strip includes a socket panel with jacks and a male electrical connector. The cables on the socket panel are connected to the male electrical connector. Because the interface of the male electrical connector of the PDU strip is special, it is not suitable for connecting with the socket. direct connection.

For a long time, the arrival of PDU sockets is based on the specifications, and the appearance is fully inspected. The power-on inspection is very difficult, which affects the inspection efficiency; It takes about 10 minutes for the cable to power up 1PCS), which may flow the defective materials with unchecked performance into the production line or send them directly to customers. If the PDU socket is not more comprehensively tested, it may cause expensive equipment to be burned, or even the entire system to crash. The cabinet cannot work normally, and even suffers major complaints from customers.

Further, the power plug is a three-phase plug.

Compared with the prior art, a PDU power-on test fixture of the utility model has the following beneficial effects:

1. This utility model aims at the problem that the interface of the PDU plug-in male electrical connector is relatively special and cannot be directly plugged into the socket for use. A PDU plug-in power-on test fixture is designed. The plug-in fit of the male electrical connector realizes the power-on inspection of the PDU socket;

2. It is designed with a leakage protector. If there is an abnormality in the tested PDU socket, such as a short circuit or leakage problem, the leakage protector can be triggered at the first time to cut off the power supply;

3. The voltage identifier is composed of an electric measuring pen with built-in components, which includes a measuring pen head, an insulating pen holder and an electric measuring pen display light. Its working principle is the same as that of the existing electric measuring pen. The difference is in the structural design. Vertically located at the front end of the insulating pen holder, the end of the measuring pen leads to three pins, forming a structure similar to a three-phase plug, one of the three pins is a conductive pin, and the rest are insulating pins; when the voltage needs to be observed, it will be measured Insert the tip of the pen into the corresponding jack of the PDU socket, touch the metal end cover with your hand, and display the on-off of the PDU socket through the neon tube indicator light, so as to visually distinguish whether it is good or bad.

To sum up, the utility model has simple structure, convenient and fast operation, and it takes about 3 minutes to detect 1PCS. It is safe and convenient to manage, reduces unnecessary abnormal situations of the cabinet in the hands of customers, and realizes the method that all PDUs can be powered on for inspection when they arrive. .
