It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.
Referring to Fig.1~Fig. 2, a kind of attachment device for preventing cable terminal from overheating comprising copper to aluminum adapter bar 2, connection
To cable termination 4 copper tip 1 and be connected to the aluminum connecting terminal 6 of external equipment terminal 5, the copper to aluminum adapter bar 2
Copper material side is connect with copper tip 1, and the aluminium side of the copper to aluminum adapter bar 2 is connect with aluminum connecting terminal 6.The copper-aluminium transition
The aluminium side of plate 2 is connect by aluminium row 3 with aluminum connecting terminal 6.It is connected with copper tip 1 on cable termination 4, contains aluminium conductor
External equipment terminal 5 on be connected with aluminum connecting terminal 6, copper tip 1 is connected with aluminum connecting terminal 6 by copper to aluminum adapter bar 2
It connects.Aluminium side and aluminum connecting terminal 6 for the ease of connection, using 3 connection copper to aluminum adapter bar 2 of aluminium row.
It is further used as preferred embodiment, the copper tip 1 is equipped with screw hole, the copper to aluminum adapter bar 2
Copper material side is equipped with screw hole, and the copper tip 1 is connected by the first bolt with the copper material side of copper to aluminum adapter bar 2.The aluminium
Row 3 is equipped with screw hole, and the aluminium side of the copper to aluminum adapter bar 2 is equipped with screw hole, and the aluminium row 3 passes through the second bolt and copper-aluminium transition
The aluminium side of plate 2 is connected.To prevent the two sides of copper to aluminum adapter bar 2 and the junction of copper tip 1 or aluminum connecting terminal 6 from going out
