DF4-9P-2C

The DF4-9P-2C Rectangular Connectors - Board In, Direct Wire to Board is a connector assembly intended to board-in the corresponding connection of a welded wire-to-board terminal and a wire-to-board terminal. It uses a solderable 10-pole connection, which is also the same as the standard DF4-9P-2C. This makes it possible to reduce the costs associated with soldering board connections.The contact interface of this DF4-9P-2C is made up of a flat 10 pin plastic block, which is connected to the board by means of a detachable solderless male connector. This type of design eliminates the risk of soldering wires to the board during installation, and it also prevents the risk of electric shock caused by the wrong kind of contact between wires and boards.The working principle of the DF4-9P-2C is quite simple. The electrical connections of the 10 pole connection are soldered simultaneously to the contact interface of the board, which is achieved by manually pressing the flat 10 pin plastic block onto the contact interface. The soldering is completed by applying enough heat using a soldering iron and then pressing the plastic blocks firmly onto the interface. The heat generated during the soldering process melts the contact area, making it easier for the lead wires to be soldered simultaneously to the contact area.The DF4-9P-2C also allows for a higher contact force. This means that the wire-to-board connection is more securely held and is less likely to be damaged by vibration or by extreme temperatures. The large size of the contact area also helps to reduce the temperature increase during the soldering process, as well as ensuring better contact stability for the connection.The DF4-9P-2C\'s board-in connection also allows for cost reduction. There is no need to purchase additional welding equipment, and the soldering process is also much faster. This type of connector is therefore ideal for applications where cost efficiency is of paramount importance.Overall, the DF4-9P-2C is an effective and reliable way to board-in a connection for a wire-to-board terminal. It is easy to install, has a large contact area for greater stability, has a higher contact force, and is much cheaper than welding. All these features make it one of the best choices for applications where cost and reliability are the key requirements.
