[0002] Generally, when the twist needles on the market are crimped, they are placed in the crimping equipment and stand on the positioning core by their own weight. Since the twist needles rely on the bulge structure of the head, the hole of the positioning core must generally be larger than the size of the bulge position, so the needle body will generally be skewed when placed in (such as Figure 1 As shown). A certain proportion of the crimped twist needle assembly will be skewed. In the later assembly of the finished product, the twist needle will be close to the inner wall. When the mismatched socket is used, the insertion and extraction force will increase, and the friction will increase, shortening the product's insertion and extraction life.

DETAILED DESCRIPTION

[0031] The following is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but they do not constitute a limitation of the utility model and are only used as examples. At the same time, the advantages of the utility model are made clearer and easier to understand through the description.

[0032] Referring to the attached drawings, it can be seen that: a twist needle crimping clamping positioning core comprises a positioning core head 1, left and right twist needle clamping pieces 2, a movable sleeve 3, a main body 4 and a round tube electromagnet 5;

[0033] The left and right clamping pieces 2 of the twist needle, the movable sleeve 3, the main body 4 and the round tube electromagnet 5 are arranged in sequence from top to bottom;

[0036] The movable sleeve 3 is sleeved on the outside of the left and right clamping pieces 2 of the twist needle and is located on the outside of the positioning core head 1; the upper and lower parts of the left and right clamping pieces 2 of the twist needle are inclined; the mouth of the movable sleeve 3 is in a fitted state after being assembled with the left and right clamping pieces 2 of the twist needle, and the upper and lower parts of the left and right clamping pieces 2 of the twist needle have a certain inclination angle, so when the movable sleeve 3 is located at the upper part of the left and right clamping pieces 2 of the twist needle, the left and right clamping pieces 2 of the twist needle are in a clamped state, clamping the twist needle head and making the twist needle in a vertical state, and when the mouth of the movable sleeve 3 is at the lower part of the left and right clamping pieces 2 of the twist needle, the left and right clamping pieces 2 of the twist needle are in a loosened state, loosening the twist needle head;

[0037] An oblong hole 1.1 is provided at the lower part of the positioning core head 1; an internal pin shaft 9 passes through the oblong hole 1.1, and both ends are respectively located on the movable sleeve 3;

[0038] The movable sleeve 3 is connected to one end of the movable connecting shaft 6 through an internal pin shaft 9;

[0039] The other end of the movable connecting shaft 6 is connected to the electromagnet movable rod 7; the round tube electromagnet 5 and the spring 8 are both sleeved on the outer circumference of the electromagnet movable rod 7; the round tube electromagnet 5 is located at the upper end of the lower end spring 8; the spring 8 is located at the lower part of the electromagnet movable rod 7;
