[0045] Thus, the base body 1 has a first positioning groove 11 into which the copper busbar H1 can be snapped. The base body 1 has a first duct 13. After the copper busbar H1 is snapped into the first positioning groove 11, the mounting hole H111 on the copper busbar H1 in the first positioning groove 11 communicates with the first duct 13. When the connector H2 is inserted into the mounting hole H111, the connector H2 can be received in the first duct 13, preventing the connector H2 from being blocked by the base body 1 during the process of being inserted into the mounting hole H111. The base body 1 has a second positioning groove 12 into which the protective sleeve H3 can be snapped. The second positioning groove 12 has a second duct 14, and the barrel H32 of the protective sleeve H3 can be inserted into the second duct 14, facilitating the maintenance of the relative position stability between the protective sleeve H3 and the base body 1. Since the copper busbar H1 and the protective sleeve H3 can be separately placed on the base body 1, the connector H2 can be directly inserted into the mounting hole H111 of the copper busbar H1. After the connector H2 is inserted into the mounting hole H111 of the copper busbar H1, the copper busbar H1 can be removed from the base body 1 and assembled with the protective sleeve H3 on the base body 1, greatly saving the assembly time and also greatly reducing the number of jigs.

Thus, the first duct 13 and the second duct 14 are relatively convenient to process.

[0049] Further, please refer to Figures 1 to 17 , as a specific embodiment of the quick-insert terminal jig provided by the present utility model, the first positioning groove 11 has a first annular groove 111 for the first annular flange H112 to snap into; the edge of the second duct 14 has a second annular groove 121 for the second annular flange H33 to snap into. Thus, after the first annular flange H112 is snapped into the first annular groove 111, the copper busbar H1 is not likely to become loose; after the second annular flange H33 is snapped into the second annular groove 121, the protective sleeve H3 is not likely to become loose.

[0050] Further, please refer to Figures 1 to 17, as a specific implementation of the quick-insert terminal fixture provided by the present utility model, the base body 1 further includes: a third positioning groove 15 for the copper bar H1 installed on the protective sleeve H3 to be snapped into; the third positioning groove 15 communicates with the second positioning groove 12.
