Rectangular Connectors, which are also referred to as Housings, are connectors most often used in high-power electronic applications such as industrial, automotive, telecommunications, and medical industry. They can be used in a variety of applications, such as fan-out/fan-in, bridging, ground loops, parallel connection, and inline connection. 794941-1 is one type of rectangular connector housing that is available in two standard versions – the Mini-Size range and the Mid-Size range. The 794941-1 application field and working principle will be discussed in this article.

794941-1 Application Field

The 794941-1 connectors are designed for both power and signal applications. They can be used in a variety of electronic applications, such as for LAN (Local Area Network) connections, data communications, and power distribution. These versatile connectors are particularly suitable for use in harsh environments, such as marine or wet areas where water, dust, and dust particles can be present. Additionally, these connectors are UL certified and meet the requirements of MIL-DTL-83723 standards for environmental and performance requirements. These connectors are also RoHS compliant, with a temperature rating of -55 to +125 ⁰C.

794941-1 Working Principle

The 794941-1 is a two-part connector comprising an outer housing (also called a case) and a contact block. The outer housing is made up of three living hinges that form a snap-lock. This allows for easy installation as no screws are required. The contact block is composed of two rows of four pins each, with contacts having different current carrying capabilities – up to 10 A per pin per row. The contacts feature insulation to ensure no cross-talk and signal degradation. Furthermore, the contacts feature a positive latching mechanism to ensure secure connection.

To ensure proper connection between the contacts and wires, the 794941-1 features a pre-insertion connection technique. With this technique, the terminals and the contact on one side of the connector are inserted into the housing before the terminals and contacts on the other side of the connector are inserted. This is done in order to provide a secure connection between the contact and the terminal block.

The 794941-1 is also designed with safety features. It has an integrated grounding feature that prevents contact corrosion and arcing, as well as a simple strain relief feature that ensures the wires remain in the correct position in order to prevent accidental disconnection.

Conclusion

The 794941-1 connector is a reliable and versatile rectangular connector housing that can be used in a variety of applications. It is suitable for both power and signal applications in harsh environments, has an integrated grounding feature for contact protection, and a pre-insertion connection technique for secure connection. Furthermore, it is UL certified and meets the requirements of MIL-DTL-83723 standard. All these features make the 794941-1 an ideal choice for rectangular connector housings.
