The wire pressing plate 400 can be slidably inserted into the mounting cavity 120 along a direction parallel to the wire arrangement plate 300, the wire pressing plate 400 is located above the wire arrangement plate 300, the wire pressing plate 400 is pushed toward the (front) of the crimping section 510 of the wire pressing terminal 500 to crimp the crimping section 510 in a direction close to the wire net 600, and the wire pressing plate 400 can push the middle section 530 of the wire pressing terminal to be abutted against the main body 100.

The pushing end of the wire pressing plate 400 is provided with a notch near the surface of the wire pressing plate 300, so that a pressing surface 420 and a pushing surface 410 are formed at the pushing end of the wire pressing plate 400, the pressing surface 420 is parallel to the wire pressing plate 300, and the pushing surface 410 is perpendicular to the wire pressing plate 300. Initially, referring to fig. 9, the flat cable 300 with the wire 600 installed therein is pushed into the installation cavity 120, at this time, the crimp segments 510 of the wire 600 are in one-to-one correspondence with the wire 600, the wire 400 is pushed into the installation cavity 120 from the open end of the installation cavity 120 horizontally, as the wire 400 is continuously pushed forward, the pressing surface 420 of the wire 400 is gradually located above the crimp segments 510 of the wire 500, the crimp segments 510 of the wire 500 are pressed downward and the crimp segments 510 are gradually deformed and retracted, during the pressing, the tip ends of the spikes 511 near the ends (named as abutting ends 512) of the crimp segments 510 first penetrate the wire 600 and scratch the insulation skin 620 along with the retraction of the crimp segments 510, the insulation skin 620 is scratched and peeled off, as all the spikes 511 enter the wire 600, the thrust surface 410 of the wire 400 is in contact with the abutting ends 512 of the wire 500, then the continuous pushing of the wire 400 is performed, the middle segment 530 of the wire 500 is rapidly pushed down under the action of the thrust surface 410 of the wire 400, and finally the pressing and the middle segment 530 is pressed down by the pushing end of the plate 400, and the abutting is completed. Compared with the mode that the spike 511 pierces the insulating skin 620 and tears the insulating skin 620 by extrusion force, the horizontal crimping mode is more reasonable for stripping the insulating skin 620, the insulating skin 620 is easier to strip and the cut is regular, so that the crimping of the line pressing plate 400 to the line pressing terminal 500 is more labor-saving, and meanwhile, the insulating skin 620 with the regular cut after stripping wraps the opposite side surface of the contact cambered surface 5111 under the influence of the self shrinkage characteristic, and further extrudes the contact cambered surface 5111, so that the spike 511 is in closer contact with the line core 610.

It can be understood that, in order to make the opening length of the plugging slot 320 as reasonable as possible, the opening length of the plugging slot 320 is slightly longer than the length of the crimping section 510 covered by all the spikes 511, the opening length of the plugging slot 320 is preferably set to accommodate the widths of slightly more than one spike 511 after all the spikes 511 are reserved, so that the spikes 511 have a sliding space, the effect of breaking the insulating skin 620 can be achieved, the movable space is not too large, and the compact and reasonable structure is ensured. Thus, in assembly, referring to fig. 9, after the flat cable 300 is inserted into the installation cavity 120, the insertion end of the flat cable 300 is spaced from the thrust surface 122 of the installation cavity, the distance is determined by that the rear end of the flat cable 300 is aligned with the thick end of the main body 100 after the flat cable 300 is inserted into the installation cavity 120, the spike 511 closest to the crimping end of the cable pressing terminal 500 just enters the inserting groove 320 in the length direction, then the flat cable 400 is pushed in from the open end of the installation cavity 120, when all spikes 511 completely enter the net cable 600, the node is determined by that the thick end of the flat cable 400 is aligned with the thick end of the main body 100, and of course, the flat cable pressing plate 300 and the flat cable 300 are jointly pushed forward until the flat cable 300 and the middle section 530 of the flat cable pressing terminal 500 are both attached to the thrust surface 122, the crimping is completed, and then the locking shell 200 is installed, so that the installation connection of the net cable 600 and the crystal head is completed.

In a further embodiment, the thrust surface 122 is a beveled surface and the angle between the thrust surface 122 and the inner top surface of the mounting chamber 120 is an obtuse angle, i.e. the thrust surface 122 is gradually closer to the insertion end of the body 100 from top to bottom. The thrust surface 122 is provided as an inclined surface, and after the crimp terminal 500 is crimped in place by the crimp plate 400, referring to fig. 10, the intermediate section 530 of the crimp terminal 500 is abutted against the thrust surface 122 and the lower end is inclined to the side near the insertion end of the main body 100. After the main body 100 is inserted into the female terminal, if the net wire 600 is pulled outwards, the net wire 600 has a tendency to drive the wire pressing terminal 500 to move outwards through the spike 511, the wire pressing terminal 500 has a tendency to move the middle section 530 away from the thrust surface 122, so that the middle section 530 has a tendency to lengthen, and the middle section 530 has a tendency to move upwards at the upper end of the middle section 530, because the wire pressing terminal 500 is pressed against the female terminal at this time, the pressing force of the wire pressing terminal 500 to the female terminal is increased due to the upward movement tendency, and further, after the conducting section 520 is pressed by the connecting terminal in the female terminal, the middle section 530 of the wire pressing terminal 500 is in a relatively stable posture, so that the quick-connection crystal head of the invention is not easy to fall off as a whole and is more pulled and tighter.

In a further embodiment, referring to fig. 4, 5 and 6, both side walls of the installation cavity 120 are provided with limiting protrusions 121, and both sides of the front end of the flat cable 300 are provided with limiting sliding grooves 330, and the lower half part of the limiting protrusions 121 is located in the limiting sliding grooves 330 to limit the upper and lower positions of the flat cable 300. The front end both sides of the line ball board 400 are provided with spacing sand grip 430, and spacing sand grip 430 is located the stopper top and with spacing lug 121 butt to the upper and lower position of line ball board 400 is spacing. Through the setting of spacing lug 121 for the position is more accurate reliable when the propulsion of winding displacement board 300 and line ball board 400, uses convenient and fast more.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
