Manufacturing method of circle type terminal used in driving motor of hybrid vehicle
The present invention relates to a manufacturing method of circle type terminal for driving motor of hybrid vehicle, comprising: assembling a terminal assembly having a plurality of bus-rings; accommodating the terminal assembly into an insert jig; coupling the insert jig with an injection mold; and supplying insert resin into the insert jig through the injection mold to integrally form an insulator with the terminal assembly thus performing manufacturing a circle type terminal, thereby providing a simple process to manufacture the circle type terminal and a method of forming an insulating material that can lower a manufacturing cost.
1. A manufacturing method of circle type terminal for driving motor of hybrid vehicle comprising:
assembling a terminal assembly having a plurality of bus-rings;
accommodating the terminal assembly into an insert jig comprising an upper insert jig and a lower insert jig which are coupled together, where the upper insert jig is formed with an injection resin flow groove to correspond to an insulator and the lower insert jig is formed with an accommodating groove to accommodate the terminal assembly;
coupling the insert jig with an injection mold; and
supplying insert resin into the insert jig through the injection mold to integrally form the insulator with the terminal assembly thus performing manufacturing a circle type terminal.
2. The manufacturing method of circle type terminal for driving motor of hybrid vehicle according to claim 1 wherein the injection mold comprises an upper injection mold and lower injection mold which is covered by the upper injection mold, the lower injection mold has a jig accommodating depression in which the insert jig is accommodated.
3. The manufacturing method of circle type terminal for driving motor of hybrid vehicle according to claim 1 wherein the injection mold comprises an upper injection mold and a lower injection mold which are coupled together, the upper injection mold is formed with an upper insert jig accommodating depression in which the upper insert jig is accommodated, the lower injection mold is formed with a lower insert jig accommodating depression in which the lower insert jig is accommodated.
4. The manufacturing method of circle type terminal for driving motor of hybrid vehicle according to claim 1 wherein the insert jig is structured to repeatedly and releasably couple with the injection mold.
5. The manufacturing method of circle type terminal for driving motor of hybrid vehicle according to claim 1 wherein the insert jig is structured to repeatedly and releasably detach from the injection mold.
6. The manufacturing method of circle type terminal for driving motor of hybrid vehicle according to claim 1 wherein the injection mold completely surrounds the insert jig under the condition that the insert jig and the injection mold are coupled together.
7. The manufacturing method of circle type terminal for driving motor of hybrid vehicle according to claim 1 wherein, under the condition that the insert jig and the injection mold are coupled together, the injection mold completely surrounds the insert jig and the insert jig completely surrounds the terminal assembly.
