Enter in the pressuring line structure of terminal；Second step melts tin cylinder or tin skin tin cylinder or the heating of tin skin, by crimping tool to crimping
Structure crimping deform pressuring line structure, the tin cylinder or tin skin after fusing deformation pressuring line structure effect under formed fill in conducting wire with
Circumferentially continuous circumferential tin layers between pressuring line structure.
Pressuring line structure is crimping set.
The end of conducting wire is covered with and the integrally formed end tin layers of circumferential tin layers.
The technical solution of crimp in the present invention are as follows:
Crimp, including being pressed for the pressuring line structure to terminal so that the upper mold of pressuring line structure deformation is under
Be provided on mold, upper mold and/or lower mold between the pressuring line structure and conducting wire tin cylinder or tin skin add
Heat is so that tin cylinder or the heating device of tin skin fusing.
Crimp further includes carrying out temperature controlled temperature control device to the heating device.
The heating device is heating tube.
The die cavity being oppositely arranged on upper mold, lower mold with accent, heating device be set to corresponding die cavity periphery or
Person's mould inside.
The invention has the benefit that in the present invention, while the crimping to the pressuring line structure of terminal, to pressuring line structure
Tin cylinder or tin Pi Jiare between conducting wire, tin cylinder or the fusing of tin skin after heating, the Xi Shui with the progress of crimping, after fusing
It can fill to any position between conducting wire and pressuring line structure, after crimping, tin water cure is to form and crimping knot
Structure and the good accessible circumferentially continuous circumferential tin layers of conducting wire.Due to during crimping Xi Shui just with pressuring line structure and lead
The problem of line forms good contact, therefore there is no Wuxi regions, while also eliminating the soldering operation of subsequent complexity.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one embodiment of terminal wiring structure in the present invention；
Fig. 2 is the structural schematic diagram of tin cylinder in Fig. 1；
Fig. 3 is the structural schematic diagram of one embodiment of crimp in the present invention.
Specific embodiment
The embodiment of terminal wiring structure is as shown in Figure 1 and 2: including conducting wire 1 and terminal 5, terminal 5 includes crimping set 2, is led
Filled with circumferentially continuous circumferential tin layers 3 between line 1 and crimping set 2, circumferential tin layers 3 are melted by the tin cylinder 12 for being located on conducting wire periphery
It is suppressed by the deformation that crimping covers.Tin cylinder it is closed at one end, after crimping, the closed end 13 of tin cylinder forms covering and leads
Thread end with the integrally formed end tin layers 4 of circumferential tin layers.
In other embodiments of the invention, tin cylinder can also be the structure of open at both ends；Tin cylinder can also be set by ring
Tin skin in conducting wire periphery replaces；The length of circumferential tin layers can also be shorter than the length of crimping set；Crimping set can also be by crimping
Other pressuring line structures such as nose, pressuring line groove replace.
The manufacturing process of above-mentioned terminal wiring structure is the embodiment of i.e. compression joint technique are as follows: the compression joint technique includes following step
Suddenly, the first step penetrates the conducting wire that periphery is equipped with tin cylinder in the crimping set of terminal；Second step melts tin cylinder the heating of tin cylinder,
Crimping set deformation is made to crimping set crimping by crimping tool, the tin cylinder after fusing is formed under the action of the crimping of deformation set to be filled
Circumferentially continuous circumferential tin layers between conducting wire and crimping set.Tin cylinder it is closed at one end, after crimping, the closing of tin cylinder
End formed covering wire termination with the integrally formed end tin layers of circumferential tin layers.Crimping tool can be Crimping Pliers and be also possible to
Crimp can heat tin cylinder by external heating device when crimping tool is Crimping Pliers, work as crimping tool
When for crimp, crimp can carry heating device, and the leakage rate of Xi Shui can also be reduced using crimp.Into
When row second step, can using on one side crimp, while the form that heats, tin cylinder can also be made to melt using first heating, rear crimping
Form, as long as can guarantee crimping terminate before, tin cylinder has been completely melt.It can also contribute to using crimping nested structure
Tin cylinder after guaranteeing fusing will not flee everywhere.
The embodiment for being exclusively used in implementing the crimp of above-mentioned compression joint technique is as shown in Figure 3: including with the upper of upper cavity 8
