Detailed Description
The present invention will be described in further detail with reference to the following examples and accompanying drawings.
The embodiment of the utility model provides a. Refer to fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, fig. 7, fig. 8. The plug comprises an electric screwdriver connecting line plug 1, wherein the connecting line plug 1 is a five-core plug, as shown in fig. 2 and 3. The connecting wire plug 1 comprises a terminal fixing frame 11 and a round tube terminal 12. The round tube terminal 12 is constituted by an insertion hole end portion 121 and a wire harness end portion 122. The terminal fixing frame 11 is a cylinder and comprises an upper part 111 and a lower part 112, the upper part 111 is provided with five terminal accommodating grooves 1111 along the outer circumference and divided into the outer circumference uniformly, and the bottom end of the terminal accommodating groove 1111 of the terminal fixing frame 11 is provided with a convex column 1112; five reinforcing ribs 1121 are provided along the outer circumference of the lower portion 112 of the terminal fixing frame 11. The bottom end of the insertion hole end part 121 of the circular tube terminal is provided with a through hole 1211, and the convex column 1112 can be inserted into the through hole 1211. Thus, the insertion hole end 121 of the round tube terminal 12 can be inserted into the terminal receiving groove 1111, and the protruding pillar 1112 is inserted into the through hole 1211 at the same time, so that the round tube terminal 12 and the terminal fixing frame 11 are fixed together; the wire harness end 122 of the round tube terminal 12 is accommodated in five accommodation areas formed by the five reinforcing ribs 1121 on the lower portion 112 of the terminal fixing frame 11.
