[0027] like Figure 1 to Figure 4As shown, a signal connector includes a shielding component 20, the shielding component 20 has a limiting recess 21, and also includes a female end base 10. In this embodiment, as shown in FIG. Figure 6 and Figure 7 As shown, the female end base 10 includes a shell 11, and the shell 11 has an installation cavity 24 for installing the shielding component 20. The lower end surface of the shell 11 is provided with a first hole 12, and the right end surface of the first hole 12 is provided with a first elastic limiting claw 13 extending to the left. The front and rear end surfaces of the shell 11 are provided with a second hole 16, and the right end surface of the second hole 16 is provided with a second elastic limiting claw 17 extending to the left. The shielding component 20 is installed in the installation cavity 24 of the female end base 10, as shown in FIG. Figure 5 As shown, a raised abutment boss 22 is provided on the upper side wall or the lower side wall of the shielding component 20, and the abutment boss 22 is located on the left side of the limiting recess 21. A limiting step 23 abutting the abutment boss 22 is provided in the mounting cavity 24, and the abutment boss 22 abuts against the limiting step 23. The first elastic limiting claw 13 and the second elastic limiting claw 17 on the female end base 10 are located in the limiting recess 21, and the claw portions 18 of the first elastic limiting claw 13 and the second elastic limiting claw 17 abut against the left end surface of the limiting recess 21. When the shielding component 20 is installed, the axial positioning of the shielding component 20 is ensured by the abutment between the abutment boss 22 and the limiting step 23 and the abutment between the claw portions 18 of the first elastic limiting claw 13 and the second elastic limiting claw 17 and the left end surface of the limiting recess 21, thereby eliminating the TPA parts and eliminating the need for TPA parts assembly, thereby reducing assembly costs and parts costs.
[0028] In this embodiment, if Figure 3 As shown, the left ends of the first elastic limiting claw 13 and the second elastic limiting claw 17 are both provided with a claw portion 18 inclined inwardly, and the inner wall of the claw portion 18 forms a wedge-shaped surface 19, and the vertical end surface of the end surface of the claw portion 18. During assembly, when the wedge-shaped surface 19 contacts the outer wall of the shielding component 20, the first elastic limiting claw 13 and the second elastic limiting claw 17 will undergo elastic deformation, thereby facilitating the insertion of the shielding component 20 into the female end base 10. When the claw portions 18 of the first elastic limiting claw 13 and the second elastic limiting claw 17 enter the limiting recess 21, the first elastic limiting claw 13 and the second elastic limiting claw 17 enter the limiting recess 21 under the action of the elastic restoring force, thereby achieving the claw portions 18 of the first elastic limiting claw 13 and the second elastic limiting claw 17 abutting against the left end surface of the limiting recess 21, thereby facilitating the assembly of the shielding component 20 and the female end base 10.
[0029] In this embodiment, if Figure 6As shown, there are two first elastic limiting claws 13 in the first hole 12, and they are arranged at intervals, so that the female end base 10 has four elastic limiting claws, that is, the shielding assembly 20 can be locked by the four elastic limiting claws, thereby meeting the holding force requirements of the female end base 10 and the shielding assembly 20.
[0030] In this embodiment, if Figure 6 As shown, a force-applying boss 14 is further provided in the first hole 12, and the force-applying boss 14 is located between the two first elastic limiting claws 13. The thickness of the force-applying boss 14 increases from left to right, and the right end of the force-applying boss 14 protrudes out of the first hole 12. Furthermore, an anti-slip strip 15 is provided on the lower surface of the force-applying boss 14. By providing the force-applying boss 14, it is convenient for the operator to hold the female end base 10 by hand, so that the shielding assembly 20 can be more conveniently inserted into the female end base 10. Moreover, after the female end base 10 and the male end base are assembled, the anti-slip strip 15 can further increase the operator's holding force on the female end base 10, thereby facilitating the pressing of the lock tongue and facilitating the separation of the female end base 10 from the male end base.
[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
