The first connector 16 is made of a first conductive material and has a first end at which the conductor 12 is disposed and a second end as a mating portion for connecting to an external electrical conductor along the length of the electrical connector terminal 14. The external electrical conductor may be a plug or other type of electrical conductor, and the first connector 16 may be connected to the external electrical conductor by a quick-plug connection or by a screw or other fastener.
In a preferred embodiment, the first end of the first connector 16 has an internal bore 20, the second connector 18 is cylindrical, and the second connector 18 is inserted into the internal bore 20 of the first connector 16. The first connector 16 may also be referred to as a conductive connector and the second connector 18 may also be referred to as a conductive adaptor sleeve. The second connector 18 has an outer layer 22 and an inner layer 24, the outer and inner layers 22 and 24 being formed of different conductive materials, the outer layer 22 contacting the bore wall of the bore 20 of the first connector 16 to form an electrical connection, and the inner layer 24 forming a wire connection to electrically connect with the wire 12. Preferably, the conductive connector 16 is provided with a groove 25 on the outer surface adjacent to the conductive adaptor sleeve 18 to position the electrical connector terminal during riveting and to eliminate deformation of the first connector 18 caused by riveting pressure. It is understood that the recess 25 may be modified to be a protrusion or other structure that achieves a similar function.
The conductor 12 includes an electrical conductor 26 and an insulation layer 28 surrounding the outer periphery of the electrical conductor 26, the end of the conductor 12 connected to the electrical connector terminal 14 has no insulation layer 28, and the electrical conductor 26 is inserted into the second connector 18 and contacts the inner surface of the inner layer 24 of the second connector 18 to form an electrical connection.
Preferably, the first connector 16 is made of pure copper, the electrical conductor of the wire 12 is made of an aluminum alloy, the outer layer 22 of the second connector 18 is made of pure copper, and the inner layer 24 is made of an aluminum alloy. Further, the electrical conductor of the wire 12 and the second connecting member 18 are made of an aluminum alloy having the same composition to prevent creep when they are connected, thereby ensuring that they are electrically connected reliably.
