Insulated moisture proof butt connector




A butt connector is used for joining two cables by crimping and shrinking.
The crimping is done at two points ( 1 ) on a metal girdle to join the cable cores from each side.
The crimp section of the connector is divided in the center by an metal tab ( 2 ) which is where the cable core ends meet.
The support sections ( 3 ) are coated with glue on the inside. When they are heated the plastic layer shrinks, the glue is released and flows out in the connector over the cable. When correctly used this method provides a strong and moisture proof joint.

Uninsulated butt connector




This type of butt connector is used in certain production operations to join cables.
To insulate the crimped butt connector a heat-shrinkable tubing is used that has an internal coating of glue. When heated the tube shrinks and the glue melts for good sealing properties and moisture protection.
Where an uninsulated butt connector must be replaced use an insulated butt connector as described in Splicing using insulated moisture proof butt connector Splicing Using Insulated Moisture Proof Butt Connector.

Branch point
Several cables can be joined together in a branch point splice.
To make a branch point use an insulated butt connector as described in Splicing using insulated moisture proof butt connector Splicing Using Insulated Moisture Proof Butt Connector.
