As shown in fig. 43-47, when it is desired to assemble the female end connector: (1) the bullet core 12 is arranged in the male needle jack 2-1-1 on the upper end surface of the female needle body 2-1; (2) assembling the female needle 2 and the female seat 4 together, and welding and fixing the wire harness 5 and the female needle 2; (3) assembling the shielding hook 9 and the female seat 4 together, and welding the shielding layer of the wire harness 5 and the shielding hook 9 together; (4) assembling the shielding shell 6 with the female socket 4; (5) assembling the female housing 7 and the shield shell 6 together; (6) assembling the female housing rear cover 10 and the female housing 7 together, and encapsulating the female needle 2, the female housing 4, the wiring harness 5, the shielding shell 6, the female housing 7, the shielding hook 9 and the female housing rear cover 10 into a whole by using the encapsulating adhesive 13, thereby obtaining the female connector.

As shown in fig. 43-47, when it is desired to mate the female connector with the male connector: and buckling the female end connector on the male end connector, so that the female seat 4 is inserted into the mounting groove 3-5 of the male seat 3, and the female needle connecting part 1-2 of the male needle 1 is inserted into the elastic core 12 in the male needle jack 2-1-1 on the upper end surface of the female needle body 2-1 after penetrating through the male needle through hole 4-2 on the upper end surface of the female seat 4, so that the elastic core 12 can tightly hoop the female needle connecting part 1-2 of the male needle 1.

In addition, in the process that the female needle connecting part 1-2 is inserted into the male needle jack 2-1-1, the guide connecting strip 4-9 slides in the guide connecting hole 3-6, the first guide strip 4-7 slides in the first guide groove 3-3, the second guide strip 4-8 slides along the second guide groove 3-4, the first clamping hook 7-1 on the female seat shell 7 slides in the first guide groove 3-3, and the second clamping hook 7-2 slides in the second guide groove 3-4. Therefore, when the female end connector is plugged with the male end connector, the first guide strips 4-7 and the second guide strips 4-8 are arranged, so that the female end connector and the male end connector can be prevented from being reversely plugged. When the female end plug connector and the male end plug connector are plugged together, the lower end face of the male seat and the upper end face of the female seat are pressed together, and although the female seat has certain compression deformation, the protection grade of IP54 is still met.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
