Abstract
The invention discloses a technological method for raising lead wire welding strength. During the process of welding and heating a circuit, a heating wire is easy to snap. In allusion to the above problem, original technologies are improved. The novel technology provided by the invention mainly comprises the following steps: (1) during the processing of welding a heating tape to a lead wire, blow molding is firstly carried out on a heat shrinkable sleeve and the lead wire part when carrying out heat shrinkage; (2) the heating tape is pushed 2-4mm into the heat shrinkable sleeve and a certain radian of a heating wire can be seen inside the sleeve by naked eyes; (3) heat shrinkage is carried out on the heat shrinkable sleeve, the heating tape part and free part of the heat shrinkable sleeve to complete the welding of the heating tape and the lead wire. By the adoption of the method provided by the invention, structural strength after welding is effectively raised and tensile performance is increased.
Description
Technical field
The present invention relates to a kind of method that improves weld strength, more particularly, the present invention relates to a kind of method that improves weld strength between the satellite assembly heater strip of heating tape and lead-in wire.
Background technology
In the solder taul process of compensation heating tape, the heater strip diameter of compensation heating tape is 0.1mm, goes between as AR-100 (line of 19 0.12mm twists into), and its diameter is about 1.2mm.In existing technical process, first by heater strip and wire bonds, put heat-shrinkable T bush and carry out blowing.Heat-shrinkable T bush and heating tape and lead-in wire are all pyrocondensations, and intermediate heat Heat-Shrinkable Tubings free end is protected heater strip, solder joint and lead-in wire.Thus, can find out that heater strip disconnection mainly contains following two possibilities: if pyrocondensation power is enough large, heater strip only may be in freely part disconnection of heat-shrinkable T bush, and under tension is broken heater strip because the free part of heat-shrinkable T bush is extended; If pyrocondensation power is large not, be likely that heat-shrinkable T bush and heating tape or lead-in wire are thrown off and cause heater strip under tension and be pulled off.After having welded by this technique, the heater strip of the free partial interior of heat-shrinkable T bush, solder joint and lead-in wire are all straight lines, if heat-shrinkable T bush extends in the time being subject to external force, heater strip will under tension, may be pulled off.Therefore, how improving weld strength between the satellite assembly heater strip of heating tape and lead-in wire is problem in the urgent need to address.
Summary of the invention
The process of the raising heating tape solder taul intensity that the present invention proposes can overcome the shortcoming of existing technique, effectively improves the resistance to tension of structure.
The method of weld strength between the heater strip end of raising satellite assembly use of the present invention heating tape and lead-in wire, mainly comprises the following steps:
First heater strip and lead-in wire are welded, heat-shrinkable T bush is wrapping in lead portion, and pyrocondensation is carried out in heat-shrinkable T bush one end of parcel lead portion, the heater strip of heating tape in heat-shrinkable T bush is advanced to 2-4mm to above-mentioned heat-shrinkable T bush one end that is enclosed with lead portion through pyrocondensation, make heater strip in sleeve pipe, present certain radian; The other end of the heat-shrinkable T bush to parcel heating tape part carries out pyrocondensation again, completes the welding of heating tape and lead-in wire.
Wherein, described pyrocondensation has been moulded by hot blow.
Weld strength between raising satellite assembly of the present invention can significantly improve heater strip and go between by the method for weld strength between the heater strip end of heating tape and lead-in wire, in the time that heat-shrinkable T bush extends, heater strip can not be pulled off.Examples prove, adopts after method of the present invention, and pull-off force is 17N, and higher than the average pull-off force 13.6N of original technique, resistance to tension is enhanced.
Accompanying drawing explanation
Fig. 1 is that before welding, heat-shrinkable T bush is wrapped in the state diagram on lead-in wire, and wherein lead-in wire is mutually close with the heater strip of heating tape.
1 is heat-shrinkable T bush; 2 is lead-in wire; 3 is that heating tape 4 is heater strip; 5 is weld pads.
Fig. 2 is the state diagram that heat-shrinkable T bush is wrapped in the rear welding lead of lead-in wire and heating tape heater strip.
Fig. 3 is that heat-shrinkable T bush moves and be arranged near the state diagram heater strip of heating tape to heater strip direction.
Fig. 4 is the state diagram after the first pyrocondensation in heat-shrinkable T bush one end of parcel lead-in wire.
To be heating tape heater strip form the state diagram after certain radian to Fig. 5 after advancing 2-4mm in heat-shrink tube.
Fig. 6 is the state diagram after the heat-shrink tube other end pyrocondensation of parcel heating tape heater strip.
The specific embodiment
1-6 describes by the method for weld strength between the heater strip end of heating tape and lead-in wire satellite assembly of the present invention with reference to the accompanying drawings.First, contrast Fig. 1, first the present invention by mutually close with the heater strip of heating tape the lead-in wire before welding, and is enclosed within heat-shrinkable T bush in lead portion.Then satellite assembly is welded with heater strip and the lead-in wire of heating tape, referring to Fig. 2, for pyrocondensation is carried out in heat-shrinkable T bush one end, heat-shrinkable T bush and lead portion are carried out to blowing, referring to the state diagram of Fig. 3, then heater strip is advanced to 2mm in heat-shrinkable T bush, make naked eyes can see that heater strip has certain radian in sleeve pipe, as shown in Figure 4, then heat-shrinkable T bush is moved near the heater strip of heating tape, state diagram as shown in Figure 5, and then heat-shrinkable T bush and heating tape part and the heat-shrinkable T bush other end carry out pyrocondensation, complete after the heater strip of heating tape and the Welding Structure of lead-in wire, said structure is applied to pulling force, and measure.Wherein, along with the increase of pulling force, heat-shrinkable T bush freely part is elongated, and in the time that pulling force reaches 17N, inner heater strip is pulled off, and breakpoint is solder joint; In the time that pulling force reaches 19N, heating tape and sleeve pipe tearaway load.
Examples prove adopts after this technique, and pull-off force is 17N, and higher than the average pull-off force 13.6N of original technique, resistance to tension is enhanced.
Carry out 4 tests by applying this process, obtain some experimental data table as follows:
According to actual operating experience, when general operation, can't be applied to 12N to heating tape, so generally heat-shrinkable T bush can not be elongated to 3mm, but twining while tiing up pipeline and may make heat-shrinkable T bush generation deformation because be wound around pipeline.
So process in application the present invention, putting before heat-shrinkable T bush pyrocondensation, one end, heating tape is advanced to 2mm more in heat-shrinkable T bush, make heater strip in heat-shrinkable T bush, have certain radian, can reach the effect that heater strip is unlikely to be pulled off in the time that heat-shrinkable T bush extends.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned embodiment according to conception of the present invention and change and revise; when its function producing does not exceed spiritual that description and accompanying drawing contain yet, all should be within protection scope of the present invention.
