[0029] like Figure 1 As shown, a vehicle-mounted connector includes a female end base 10, such as Figure 4 and Figure 5 As shown, the female end base 10 is provided with an installation cavity 11, and a shielding assembly 30 is installed in the installation cavity 11. The shielding assembly 30 has a limiting recess 31, as shown in FIG. Figure 2 As shown, a locking hole 13 is provided on one side wall of the female end base 10, and the locking hole 13 is connected to the installation cavity 11. Figure 6 As shown, a locking member 20 is installed in the lock hole 13. After the locking member 20 is installed, the locking member 20 clamps the shielding assembly 30, thereby limiting the axial retreat of the shielding assembly 30. Further, as shown in FIG. Figure 7 As shown, the locking member 20 includes a pressing portion 22, and the upper and lower ends of the inner end surface of the pressing portion 22 are provided with protruding clamping portions 23, a clamping groove 24 is formed between the two clamping portions 23, and the limiting recess 31 is stuck in the clamping groove 24, so that the upper and lower surfaces of the limiting recess 31 are in contact with the corresponding clamping portion 23, thereby increasing the force-bearing area of ​​the locking member 20 and the shielding assembly 30, thereby ensuring the holding force of the locking member 20 on the shielding assembly 30. In this embodiment, with the insertion direction of the shielding assembly 30 as the front, when the locking member 20 is installed, the front end surface of the clamping portion 23 abuts against the front end surface of the limiting recess 31, thereby preventing the shielding assembly 30 from axial retreat, and in this embodiment, as Figure 4 As shown, a limiting step 12 is provided in the installation cavity 11, and a raised limiting protrusion 32 is provided on the shielding component 30, and the limiting protrusion is located in front of the limiting recess 31. When the shielding component 30 is installed, the limiting protrusion 32 abuts against the limiting step 12. That is to say, when installing the shielding component 30, after the shielding component 30 is inserted into the female end base 10, when the limiting protrusion 32 abuts against the limiting step 12, it indicates that the shielding component 30 is inserted into place, and then after the locking piece 20 is installed in the locking hole 13, the front end face of the clamping portion 23 abuts against the front end face of the limiting recess 31, thereby ensuring the axial fixation of the shielding component 30.

[0030] In this embodiment, if Figure 3As shown, a through hole 14 is provided on one side wall of the female end base 10, and the through hole 14 is connected to the installation cavity 11, and the through hole 14 is arranged opposite to the lock hole 13, and an avoidance groove 15 is provided on the upper and lower side walls of the through hole 14, and the avoidance groove 15 extends toward the lock hole 13, and a stop step is formed at the lock hole 13, and an elastic arm 21 corresponding to the avoidance groove 15 is provided at the connection between the pressing portion 22 and the clamping portion 23, and the elastic arm 21 extends toward the pressing portion 22, and the elastic arm 21 is inclined toward the outside of the pressing portion 22, when the locking member 20 is installed in the lock hole 13, the end of the elastic arm 21 abuts against the stop step, when installing, the clamping portion 23 is inserted from the lock hole 13, and then the pressing portion 22 applies a thrust, after the elastic arm 21 contacts the inner wall of the lock hole 13, the elastic arm 21 is elastically compressed, and the elastic arm 21 generates an elastic restoring force, when the elastic arm 21 is elastically compressed, the elastic arm 21 generates an elastic restoring force, and ... After the elastic arm 21 completely enters the avoidance groove 15, the elastic arm 21 resets under the action of the elastic restoring force. At this time, the end of the elastic arm 21 abuts against the stop step, thereby preventing the locking piece 20 from withdrawing from the lock hole 13, thereby ensuring the reliability of the installation of the locking piece 20. Furthermore, two avoidance grooves 15 set at intervals are provided on the upper and lower side walls of the through hole 14, that is, the upper and lower surfaces of the locking piece 20 have two elastic arms 21, which further increase the reliability of the installation of the locking piece 20. When the shielding component 30 needs to withdraw from the female end base 10, a special tool can be used to insert it from the avoidance groove 15, and then the elastic arm 21 is compressed and deformed, and then an outward withdrawal thrust is applied to the locking piece 20, so that the compressed elastic arm 21 enters the lock hole 13, thereby facilitating the unlocking of the locking piece 20.

[0031] In this embodiment, if Figure 2 and Figure 5 As shown, an elastic limit block 16 is provided on the end face of the through hole 14 away from the avoidance groove 15, and the end of the elastic limit block 16 abuts against the end face of the limiting recess 31. Furthermore, the end of the elastic limit block 16 is a claw portion inclined inwardly, and the end face of the claw portion abuts against the end face of the limiting recess 31. The inner side wall of the claw portion is a wedge-shaped surface. During the insertion process of the shielding component 30, after the shielding component 30 contacts the claw portion, the elastic limit block 16 is deformed, and the elastic limit block 16 generates an elastic restoring force. When the elastic limit block 16 passes over the front end of the shielding component 30 and enters the limiting recess 31, the elastic limit block 16 is reset under the action of the elastic restoring force. At this time, the end face of the claw portion of the elastic limit block 16 abuts against the front end face of the limiting recess 31, so that the shielding component 30 can be initially positioned in the axial direction, thereby avoiding interference between the locking member 20 and the shielding component 30 during the installation process, and facilitating the installation of the locking member 20.

[0032] In this embodiment, if Figure 7As shown, the outer end surface of the pressing portion 22 is provided with a cover plate 25 matching the locking hole 13. When the cover plate 25 is flush with the outer side wall of the female end base 10, it indicates that the locking member 20 is installed in place. Furthermore, the locking hole 13 can be set as a step hole, and the height of the small hole of the locking hole 13 in the up and down directions is greater than the height of the pressing portion 22, while the height of the large hole of the locking hole 13 matches the height and width of the cover plate 25. Then, during installation, when the cover plate 25 abuts against the large hole of the locking hole 13, the surface locking member 20 is installed in place.

[0033] In the existing vehicle-mounted connector, during the unlocking process of the female base 10 and the male base, the lower surface of the female base has no force application point and is smooth, which causes asymmetric force on the upper and lower surfaces of the female base 10, making it difficult to pull out. In this embodiment, an inclined force application surface 18 is provided on the lower side wall of the female base 10, and a plurality of anti-slip strips 19 are provided on the force application surface 18. When the female base 10 and the male base need to be disassembled, external force is applied to the force application surface. Since the force application surface has the anti-slip strips 19, the disassembly of the female base 10 and the male base is facilitated.

[0034] 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.
