It is interior, it is welded in the contact position at the middle part of the end face and conducting wire core wire 2 of telescopic contact 3.This end on structure is only applicable to lead
The case where core cable architecture is sub-thread silk, and meeting damage wires core wire when welding reduce tensile strength, such contact termination knot
The less use of structure.
Second class is the end on structure using solder, is contacted in conducting wire core wire 2 with telescopic as shown in Fig. 2, solder 4 is filled
Between part 3, this end on structure is only applicable to the material of easy tining, and such end on structure has the disadvantages that and 1) leads to realize
Solder 4 between core line 2 and telescopic contact 3 it is full with it is full, need longer weld interval and enforcement difficulty compared with
Greatly；2) fusing point of solder 4 is higher, and the weld interval needed is longer, is easy to cause the damage of telescopic contact mechanical life, shadow
Ring the reliability of plug；3) conducting wire welding position is located at the tail end of telescopic contact, and it is existing easily to occur climbing tin in welding process
As causing the conducting wire of telescopic contact tail end firmly crisp, conducting wire axis direction tensile strength is higher, but cuts to non-axis direction
The ability to bear of shear force is weaker, and under mechanical load function, conducting wire easy fracture is disengaged；4) it is influenced by 4 fusing point of solder, uses temperature
It is limited to spend the upper limit, when operating temperature is higher, solder 4 can melt, and conducting wire and telescopic contact disengage.
The conducting wire core wire of above-mentioned two classes contact member termination structure will receive the influence of welding and generate mechanical strength reduction
The problem of, to reduce the connection reliability of contact member termination structure；First class formation is suitable for the conducting wire of sub-thread silk, the second class
End on structure is suitable for easily climbing the material of tin, and use is temperature limited, and the use scope of two class end on structures is relatively narrow.
