Description
Technical field
The present invention relates to a kind of contact member termination structure.
Background technology
Contact common at present welds the contact member termination structure to be formed with wire two classes.The first kind is without using weldering
The end on structure of material, as shown in figure 1, wire termination removes wire insulation 1, wire cored wire 2 is inserted into telescopic contact 3
It is interior, welded in the end face of telescopic contact 3 with the contact position at the middle part of wire cored wire 2.This end on structure is only applicable to lead
Core cable architecture is the situation of sub-thread silk, and can damage wires cored wire, reduction tensile strength, such contact termination knot during welding
Structure is less to be used.
Equations of The Second Kind is the end on structure using solder, is contacted as shown in Fig. 2 solder 4 is filled in wire cored wire 2 with telescopic
Between part 3, this end on structure is only applicable to the material of easy tining, and such a end on structure has the disadvantages that：1）Led to realize
Solder 4 between core line 2 and telescopic contact 3 it is full with it is full, it is necessary to longer weld interval and enforcement difficulty compared with
Greatly；2）The fusing point of solder 4 it is higher, it is necessary to weld interval it is longer, be easily caused the damage of telescopic contact mechanical life, shadow
Ring the reliability of plug；3）Wire welding position is located at the tail end of telescopic contact, easily occurs in welding process climbing tin and shows
As causing that the wire of telescopic contact tail end is firmly crisp, wire axis direction tensile strength is higher, but non-axis direction is cut
The ability to bear of shear force is weaker, under mechanical load function, and wire easy fracture is disengaged；4）Influenceed by the fusing point of solder 4, use temperature
Spend the upper limit to be limited, when operating temperature is higher, solder 4 can melt, wire is disengaged with telescopic contact.
The wire cored wire of above-mentioned two classes contact member termination structure can by weld influenceed and produce mechanical strength reduction
The problem of, so as to reduce the connection reliability of contact member termination structure；First class formation is applied to the wire of sub-thread silk, Equations of The Second Kind
End on structure is applied to easily climb the material of tin, and temperature in use is limited, and the use scope of two class end on structures is narrower.
The content of the invention
It is an object of the invention to provide a kind of contact member termination structure, tied with solving contact termination of the prior art
The wire cored wire of structure is caused the problem of its mechanical strength is reduced by welding influence.
To solve the above problems, the contact member termination structure in the present invention is adopted the following technical scheme that：Contact termination knot
Structure includes being arranged with hollow contact and the wire cored wire for being inserted into contact inside and being connected with contact, wire cored wire
Reducing sleeve, reducing sleeve is welded with contact, is had on reducing sleeve on the insertion end for the insertion of wire cored wire, reducing sleeve away from insertion
The end of the one end at end and wire stylet wire bonding.
The cylinder for being shaped as two ends insertion of the reducing sleeve, inner peripheral surface and the wire cored wire gap of reducing sleeve coordinate.
The contact is columnar telescopic contact, the inner peripheral surface of telescopic contact and the outer peripheral face of reducing sleeve
Gap coordinates.
Extend the end face of contact in the end of the insertion end of reducing sleeve.
The pad of the one end of the reducing sleeve away from insertion end and wire cored wire is located at the end of reducing sleeve.
The end face of the one end of the reducing sleeve away from insertion end, which is provided with along what reducing sleeve axis direction extended, to be used for leading
The solder-bump of core line melting connection.
The solder-bump is extended by the side wall of reducing sleeve and formed.
At least one is welded by argon arc welding between wire cored wire and reducing sleeve, between reducing sleeve and contact.
The insertion end of reducing sleeve and the end of contact are welded.
Pad between the reducing sleeve and contact is located at the side of contact radial direction.
The beneficial effects of the invention are as follows：Reducing sleeve is set between contact and wire cored wire, and reducing sleeve is respectively with contacting
Part and wire stylet wire bonding, tail end and end of the reducing sleeve away from insertion end of wire cored wire are welded, and reduction welding is to wire stylet
The damage of line, while avoid wire cored wire during welding climbs the hard crisp problem of wire cored wire caused by tin, it is ensured that wire cored wire
Bonding strength, improves the connection reliability of contact member termination structure.
