The 1677979 two-piece, heavy duty, SMT-type connector is widely used in many electronic applications. It is a common type of contact array used in various industries, such as telecommunications, automotive, aerospace, and more. Essentially, the 1677979 connector has two parts – the housing and the base. The housing is the part that covers the contacts, and the base is the part that sits on the printed circuit board and mates to the housing.

Housing

The housing is the outer shell of the 1677979 connector, and is made from a material such as plastic or metal. The housing must be able to protect the internal contacts and keep them aligned, as misplaced pins can cause connection problems. The housing must also ensure a tight fit without compromising the EMI/EMP protection.

Hoods

The hood of the connector is the part that connects the two pieces together and provides the necessary seal. It is often made from a semi-rigid material such as plastic, and is designed to be waterproof and dustproof. One of the most critical aspects of the hood is its ability to ensure stable electrical connectivity without external interference.

Bases

The base of the 1677979 connector is the part that sits on the PCB and is used to mount the housing to the board. The base is designed to provide the mechanical strength to keep the entire assembly together, and also ensures strong electrical connections between the contacts and the PCB. The base must be designed to minimize the mating force, yet provide the necessary rigidity.

Working Principle

The 1677979 contact array has two primary components - the housing and the base. The connecting elements between them are the hoods which provide the seal and the latches which ensure a mechanical connection between the housing and the base. Once the housing is aligned and secured to the base, the contacts on the housing make electrical contact with the contacts on the PCB.

To push the pins on the housing into contact with the contacts on the PCB, a pin presser is used to activate the contact. This pin presser, which is mounted onto the board, applies pressure to the contacts to make the electrical connectivity. Once the pins are inserted the pin presser is released and the contacts remain in contact with each other, providing a secure and stable connection.

Conclusion

The 1677979 connector is a two-piece, heavy duty, SMT-type connector used in many electronic applications. It is composed of a housing, hoods, and a base. The housing is responsible for protecting the internals and keeping them in alignment, while the hood provides the necessary seal. The base is the part that sits on the PCB to provide mechanical strength and electrical contact. The pin presser is also used to secure the connections between the contacts. When used together these components provide strong and stable electrical connections.
