Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors are reliable and efficient electrical connections that provide robust, secure, and long-lasting electrical connections. They are used in a wide variety of applications, from audio and video equipment to power electronics and medical equipment. This article will discuss the 91601-308 application field and working principle.

Introduction to 91601-308

The 91601-308 is a rectangular connector with a 2x1.5 mm footprint. It is designed with an electromagnetic interference (EMI) shielding to protect sensitive circuits from the unwanted inward or outward flow of electromagnetic interference. It offers insulation displacement contact (IDC) termination with a contact material of phosphor bronze given a maximum current capacity of 3A. Complex designs can be realized as per one’s need with a solderless assembly.

Applications

The 91601-308 is widely used in the power supply, lighting, instruments, consumer electronics, automotive electronics, office equipment, wireless communication, POS machine and other industries. It is used in the power port of mobile phones and machines, the power port of small appliances, and the charge port of interphone. In addition, this connector can also be used in combination with the crimping pin-header to provide robust and reliable electrical connections for different types of electronic devices.

Working Principle

The working principle of the 91601-308 is based on the concept of insulation displacement contact (IDC). IDC contact is an efficient wire terminating technology that utilizes a “blade” mechanism to pierce through the insulation of a stranded wire and make contact with the conductor inside. Since the length of the blade is far shorter than the insulation, extra space is saved inside the connector, allowing for a smaller form factor. By cutting away the insulation, the wire is securely connected to the contact inside the connector mechanism.

In a 91601-308 connector, the contact blades are made from a material such as phosphor bronze or stainless steel. When used in conjunction with an adequate insulation, it can offer secure interconnect performance and prevent EMI interference. The contact wears a sharpened bevel-edge that slices through the insulation of the wire and establishes a good connection with the conductor. The blade contact provides a reliable connection that\'s current-stable, and its blades are designed for multiple wire cross-sections of different sizes.

Conclusion

The 91601-308 is a versatile rectangular connector with a 2x1.5 mm footprint. It offers IDC termination with a contact material of phosphor bronze given a maximum current capacity of 3A. Furthermore, it provides EMI shielding to protect sensitive circuits from electromagnetic interference. This connector can be used in a wide variety of applications from audio and video equipment to medical equipment and power electronics. It offers a secure connection with current-stable and reliable performance.
