BLL1BSK16029XN

Circular Connectors are indispensable tools to connect electrical and electronic devices in many modern applications. Among all kinds of circular connectors, Backshells and Cable Clamps play an inevitable role in most of the applications. The BLL1BSK16029XN is considered as one of the most popular products among these. This part includes both the backshell and the strain relief clamp and suitable for applications that require compatibility with the MIL-DTL-38999 Series III power, blind mate and tri-start connectors.

The BLL1BSK16029XN is able to provide a 90° strain relief along the backshells of the connectors. Itt’s designed with double "U" shaped flange mount clamps which can provide positioning and protection to the cables’ overmold which ensure the stability of the connection. Furthermore, the 360° EMI gasket ensures reliable EMI/RFI shielding.

Application fields and Availability

The BLL1BSK16029XN is designed mainly for aerospace, military, industrial and commercial applications that use tri-start, power or blind-mate connectors. This part is normally found in sensitive electronic equipment such as sensors, control systems, high-speed data transfer networks, aerospace, in-flight test systems and military applications. Thus, it’s also labeled as MIL-DTL-38999 III Connector.

The BLL1BSK16029XN backshell and cable clamps can accommodate 4-18 contacts. There are three different sizes available in the range depending on cable diameter; 4 for 2.02 – 7.98mm, 5 for 7.99 – 12.46mm, 6 for 12.47 – 16.94mm. In terms of materials, the strain reliefs are usually made up of zinc die-cast with an AFS electroplated. The gaskets are normally made up of copper and the armoured cable shields are made of beryllium.

Working Principle

The working principle is quite simple. The BLL1BSK16029XN clamps first fit on the cable clamp and then screw onto the backshell. Once on, the backshell gets connected to its mating connectors. After the tension is applied correctly to the connection, the strain relief clamps hold the cable securely and prevent any unwanted movements or damage. It also ensures that the environmental performance is maintained at all times.

The Mate/Demate functions of the BLL1BSK16029XN are relatively simple and they have minimal requirements for maintenance. As with any connector, latching or re-latching of the BLL1BSK16029XN can be done to check for the fastening of the cable clamp in the inner channel of the backshell. This latching process takes very little effort.

In conclusion, The BLL1BSK16029XN is an important part in the range of circular connectors. It offers a high level of compatibility with the MIL-DTL-38999 Series III and offers great EMI/RFI shielding. For applications that require tri-start, blind-mating or power connectors, the BLL1BSK16029XN is a very suitable product.
