[0032] Preferably, the crimping cable hole 104 can be matched with the cable by a tube expansion or tube shrinking process.

[0033] like Figures 1 to 4 As shown, the jack connector 101 and the intermediate connector 102 are both cylindrical, and the front end of the jack connector 101 is rounded. By setting the jack connector 101 and the intermediate connector 102 to be cylindrical, the smoothness of plugging the jack connector 101 is improved.

[0034] It is worth noting that a plating layer is provided on the contact area of ​​the jack connector 101 , so as to form a contact protection layer on the outer side of the jack connector 101 and improve the contact stability of the jack connector 101 .

[0035] Specifically, the crimped cable rear shell 103 is formed at the rear end of the intermediate connector 102 by an extrusion molding process. This simplifies the process of processing and molding the crimped cable rear shell 103. The crimped cable rear shell 103 is processed by extrusion molding, replacing the traditional welding processing method, reducing environmental pollution and safety hazards caused by exhaust gas generated by the welding process.

[0036] Preferably, the cross section of the crimped cable rear shell 103 after riveting is hexagonal, so as to ensure the contact stability between the crimped cable rear shell 103 and the cable.

The connecting spring 2 is sleeved on the outer side of the intermediate connecting body 102 by connecting the fixing spring 202 and the intermediate connecting body 102 to each other.

[0040] like Figure 4 As shown, the intermediate connector 102 cooperates with the cable crimping rear shell 103 to form an assembly boss, and a plurality of fixing springs 202 are fixedly connected to the assembly boss, so that the fixing springs 202 can be assembled and fixed through the assembly boss.

[0041] like Figures 5 and 6 As shown, multiple snap-fit ​​springs 203 are integrally formed at one end of the spring body 201, and the multiple snap-fit ​​springs 203 are tilted toward the outside of the spring body 201. It is convenient to assemble and limit the terminal body 1 through the mutual cooperation of the multiple snap-fit ​​springs 203 and the high-current power supply terminal plastic shell.

[0042] Preferably, the spring body 201, the plurality of fixing springs 202 and the plurality of engaging springs 203 are all made of copper, thereby ensuring the conductive performance of the connecting spring 2.

[0043] During the processing, the solid round rod material is placed in a predetermined mold, and after multiple composite extrusions, the jack connector 101, the intermediate connector 102 and the crimped cable back shell 103 are formed.

When in use, the cable is inserted into the crimping cable hole 104 for shrinking, and the cable is assembled in the crimping cable hole 104 by riveting, and then the terminal body 1 and the connecting spring piece 2 are inserted into the plug hole of the plastic shell, and the terminal body 1 is quickly assembled by the mutual engagement of the plurality of snap-fit ​​spring pieces 203 with the card slots in the plastic shell.
