DF3E-7P-2H(20) Application Field and Working Principle

Rectangular Connectors - Headers, Male Pins plays an important role in the electronic industry. DF3E-7P-2H(20) is one of the rectangular connectors, with its application field and working principle.

1. Application Field of DF3E-7P-2H(20)

DF3E-7P-2H(20) is widely applied in various sectors such as home appliances, precision machinery, electronics, medical treatment, military industry, automotive audio, household electrical appliances, computer and peripherals, etc. In addition, it can also be used in the production of electronic modules, data communication, test measurement, equipment control, power management and other related fields.

2. Working Principle of DF3E-7P-2H(20)

DF3E-7P-2H(20) is a kind of male pin type connector. It is with two long (20mm) pins, without terminal or tapping feet, and the two pins have a “shoulder”. This kind of connectors adopts snap type electrical connection and pin insertion way. When it is connected, the “shoulder” will be stuck by the slot in the connecting port and make it stable. In order to make sure DF3E-7P-2H(20) works perfectly in the application, users often choose IC sockets or fit IC terminals as the connection parts. This kind of connectors also have good electrical insulation such as high temperature resistance and low temperature resistance.

3. Advantages of DF3E-7P-2H(20)

As a kind of rectangular connectors, DF3E-7P-2H(20) is widely applied because of the following advantages:

• High reliability and flexibility: When it is connected, physical means is used, there is no electric arc or oxidation caused in the slot, which can effectively reduce the contact resistance, and make sure its working performance. In addition, its flexibility can meet different working conditions;
• Easy installation: It has snap type electrical connection and pin insertion way, the two pins can be easily installed into the mating parts, and the same times can effectively reduce the time of installation;
• Easy maintenance: It can be easily maintained with reducing the quality of components’ damages caused by plugging and unplugging, which can reduce the cost of electronic repair.

4. Application Warning of DF3E-7P-2H(20)

When users purchase and apply DF3E-7P-2H(20), they should take notice of the following points:

• No dust to be allowed: The dust may cause contacts failure. They can use clean cloth and purified alcohol to clean up the slot for getting a better connection;
• No extra force to be given: Extra force may cause wrong contacts, so clamps should be used to reinforce connections;
• No short/over length insertion to be allowed: The insertion may cause contact failure or no stable connections.

5. Summary of DF3E-7P-2H(20)

In conclusion, DF3E-7P-2H(20) is an kind of rectangular connectors, it is widely used in a variety of electronic products and machinery due to its high reliability and great flexibility. With the snap type electrical connection and pin insertion way, it can make sure its working performance. At the same time, users should also take full attention when using DF3E-7P-2H(20), otherwise it may cause contact failure or wrong contacts.
