How should a plastic detonating connector be attached to detonating cord?

• A. By twisting the ends and inserting into the connector
• B. By cutting the cord and making a U shape
• C. By using adhesive to secure the ends into the connector
• D. By welding the ends to the connector

Answer: (B)

Attaching a plastic detonating connector to detonating cord by cutting the cord and making a U shape is the appropriate method because it ensures a secure and reliable connection. In this technique, the detonating cord is formed into a U shape when inserted into the connector, allowing for a tight fit that enhances the transmission of the detonation wave. This design minimizes the risk of misfires or incomplete detonation, which can occur if the connection is not optimal.

The other methods are less effective for ensuring a secure and safe connection. For example, twisting the ends and inserting them into the connector does not guarantee a complete and firm connection, potentially compromising the effectiveness of the detonation. Using adhesive might introduce inconsistencies and weaken over time, leading to a failure in the detonation process. Welding the ends to the connector can be impractical and might not accommodate the materials involved in a safe manner, presenting added risks in an explosive environment. Therefore, making a U shape is the most effective and reliable method for connecting a plastic detonating connector to detonating cord.
