Abstract
The utility model relates to a stress relieving type contact element welding structure with preset welding flux, which is composed of a contact body, soldering tin bars and a heat-shrinkable tube. Quantitative soldering tin bars are wound on a welding part at the tail end of the contact body in advance, the transparent high-temperature heat-shrinkable tube is sleeved on the soldering tin bars at the tail part of the contact body and shrunk and shaped in advance so as to fix the soldering tin at the tail part. When the stress relieving type contact element welding structure is used, a wire penetrates through the heat-shrinkable tube and inserted into a welding hole of the contact body, the welding part is heated uniformly by heating equipment such as an electric hair drier and the like to melt the soldering tin, and meanwhile, the heat-shrinkable tube contracts and oppresses the melt soldering tin to flow into the welding hole through a side hole of the welding part, thereby realizing welding between the contact element and the wire. The tail part of the contact element and the wire are coated by the heat-shrinkable tube after contacting, thereby eliminating impacts imposed on the welding part by external force. Whether the wire on the welding part is in place or not and the wielding quality can be detected through the transparent heat-shrinkable tube and the side hole at the tail end of the contact body after welding.
Description
Technical field
The utility model relates to a kind of contact Welding Structure, is a kind of quantitative scolder that presets, and can eliminate external force to the impact of welding position, operates and detect easy Welding Structure.
Background technology
At present, the structure of contact welding lead commonly used is that bonding wire is flat or weld cup typely, generally adopts manual welding.During use, by electric iron, the welding position straight is connect heating, fill scolder in the welding position and realize contact and wire bonds.Due to the scolder non-quantitative, cause a collection of contact welded condition inconsistent; The welder of different levels, during welding same contact, quality of welding spot has gap; Due to manual operations, wire and contact axis are inconsistent, cause that in follow-up use, the welding position is stressed; Due to structural limitations, can not realize batch production, efficient is lower.
Summary of the invention
The problems such as be subjected to artifical influence factor large in order to solve existing contact Welding Structure, integrality and quality conformance are poor, and welding position stress can not effectively be eliminated and efficient is low.The utility model provides a kind of contact Welding Structure, this structure effectively reduces the human factor impact, guarantee final welded condition and quality conformance, can eliminate the impact of welding position stress and external force butt welding point, and can realize contact and wire bonds mass demand.
The technical scheme that its technical problem that solves the utility model adopts is: the present invention is a kind of stress elimination type contact Welding Structure that presets scolder, consisted of by contact, soldering tin bar and heat-shrinkable T bush, it is characterized in that: preset scolder in the contact welding position, scolder should wrap up contact one week of welding position, by high temperature transparent heat Heat-Shrinkable Tubings, scolder is fixed in the contact welding position.
Have side opening on contact afterbody welding position bonding wire hole wall, a certain amount of soldering tin bar is wrapped in outside contact tail end side opening in advance, make it surround contact one week of welding position, be enclosed within on contact afterbody soldering tin bar and the preshrunk moulding with transparent high temperature heat-shrink tube again, fixing on contact to realize afterbody scolding tin.During use, wire passes heat-shrink tube and inserts in the contact welding hole, by firing equipments such as hair dryers to the welding position homogeneous heating, scolding tin is melted, heat-shrinkable T bush shrinks but is not destroyed, and the heat-shrinkable T bush compressing melting scolding tin of contraction is by realizing contact and wire bonds in side opening inflow bonding wire hole, contact welding position.Quantitative and the welding temperature term harmonization due to scolder can guarantee the rear state of contact welding and quality conformance; The heat-shrinkable T bush of contact afterbody is coated on contact afterbody and wire after shrinking, and guarantees that contact is consistent with the axis of termination wire, and eliminating external force affects the welding position; After welding, see through transparent heat Heat-Shrinkable Tubings and contact tail end side opening, can detect the welding position wire and whether put in place and welding quality; Wire pack into contact bonding wire hole and put in place after, can be in a kind of heating environment to a collection of contact heating welding, realize batch production.
The beneficial effects of the utility model are, simple realization solder type contact and wire bonds state and quality conformance, and eliminating welding stress and external force affects the welding position, and can adapt to contact and produce in batches with wire bonds, simple in structure, easy and simple to handle.

1. contacts in figure, 2. soldering tin bar, 3. heat-shrinkable T bush, 4. wire.
Embodiment
In Fig. 1, soldering tin bar (2) is placed in contact (1) afterbody perforate position, makes it be wound around contact one week of welding position, and heat-shrinkable T bush (3) is enclosed within on contact afterbody soldering tin bar and the preshrunk moulding realizes that afterbody scolding tin fixes.
In the embodiment shown in fig. 3, wire (4) passes heat-shrinkable T bush (3) and inserts in contact (1) welding hole, by firing equipments such as hair dryers to the welding position homogeneous heating, soldering tin bar (2) is melted, and the heat-shrinkable T bush of contraction (3) compressing melting scolding tin is by realizing contact (1) and wire (4) welding in side opening inflow bonding wire hole, contact (1) welding position.After heat-shrinkable T bush (4) shrinks in welding process, be coated on contact (1) afterbody and wire (4), eliminating external force affects the welding position; By transparent heat Heat-Shrinkable Tubings (3) and contact (1) tail end side opening, can detect welding position wire (4) and whether put in place and welding quality.
Claims (3)
1. a stress elimination type contact Welding Structure that presets scolder is made of contact, soldering tin bar and heat-shrinkable T bush, it is characterized in that: preset scolder in the contact welding position, scolder should wrap up contact one week of welding position, by high temperature transparent heat Heat-Shrinkable Tubings, scolder is fixed in the contact welding position.
2. contact Welding Structure according to claim 1 is characterized in that the contact welding position puts the high temperature heat-shrinkable T bush, is subjected to the heat-shrinkable T bush compressing of thermal contraction to melt scolding tin and flows into the bonding wire hole, and eliminate external force the welding position is affected.
3. whether contact Welding Structure according to claim 1, is characterized in that having side opening on contact bonding wire hole wall, by side opening, can detect welding lead and put in place and welding quality.
