[0006] As a preferred, the inner mold upper cover and the inner mold lower cover of the false inner mold are fixed by buckle connection.

[0007] As a preferred, the inner mold upper cover and the inner mold lower cover are provided in a side flipping or separation structure.

[0008] As a preferred, the line outlet of the false inner mold is provided with a pin corresponding to the number of terminal placement holes on the glue core, and the pin is inserted into the terminal placement hole.

[0009] As a preferred, the line inlet of the false inner mold is arranged at the back end or the rear end of the false inner mold.

[0010] A buckle type false inner mold connector processing technology, comprising the following steps:

[0011] S1: Use a wire stripping tool to process the outer mold and core wire sheath of the terminal connection wire. Remove 19-21mm of the outer mold at both ends of the terminal connection wire and remove 2-4mm of the core wire sheath.

[0012] S2: Attach terminals to both ends of the stripped core wire;

[0013] S3: Insert the crimped terminal wires into the corresponding terminal placement holes of the rubber core in sequence;

[0014] S4: Install the dummy inner mold, place the terminal connection wire at the wire inlet of the dummy inner mold, and fasten and fix the flip cover of the dummy inner mold with the buckle;

[0015] S5: Push the snap-fit ​​dummy inner mold to the terminal placement hole at the rear end of the rubber core, and use the jig to completely install the wire outlet of the dummy inner mold into the rubber core.

[0016] S6: Molding and protecting the outer mold. Place the terminal connecting wire with the dummy inner mold installed into the outer mold forming machine to process and form a complete wire.

[0017] The beneficial effects of this invention are as follows: The use of a snap-on dummy inner mold provides a detachable design, and the placement of the inlet port in different positions allows the connecting wire to enter from various angles. During product installation, the terminal connecting wire can be first installed into the core and tested for power-on. If the test is successful, the dummy inner mold can be installed, and finally, the outer protective mold is applied. This invention has a simple structure and is convenient and quick to use. By designing the dummy inner mold with a side-opening structure, it ensures that the terminal connecting wire can be successfully powered on after installation into the core. The dummy inner mold is then installed and fixed to the rear end of the core, which improves the yield rate of finished products, reduces time wasted due to defective products, and lowers the company's production costs.
