[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a windshield wiper connector. (Refer to...) Figure 1The wiper connector includes a connector body 1 and a connecting base 2. The upper side of the connector body 1 is used to connect the wiper arm, and the bottom of the connecting base 2 is used to install the wiper blade 3. The connector body 1 and the connecting base 2 are detachably connected. This detachable connection means that when the wiper needs to be replaced, only the wiper blade and the connecting base 2 need to be replaced, while the connector body 1 remains unchanged, thus reducing the cost of wiper replacement. In this embodiment, to improve vehicle compatibility, the connector body 1 can be detachably connected to the connecting base 2 via a detachable replacement clip.

[0029] Reference Figure 2 and Figure 3 The connector body 1 has a downward-protruding limiting insert 11 at its bottom. A plug-in block 12 extends horizontally from one end of the limiting insert 11 and is located on the side wall of the limiting insert 11 away from the bottom of the connector body 1. The lower surface of the plug-in block 12 is flush with the lower surface of the limiting insert 11. A snap-fit ​​block 13 is located at the bottom of the connector body 1, and the snap-fit ​​block 13 has snap-fit ​​grooves 131 that communicate on both sides. The upper surface of the connecting base 2 has a downward-facing hollowed-out limiting through groove 21 for the limiting insert 11 to be inserted into. The end of the connecting base 2 has a receiving groove 22, which is close to and communicates with the limiting through groove 21. A snap-fit ​​post 23 is horizontally fixed at one end of the limiting through groove 21. The plug-in block 12 can be inserted into the receiving groove 22 through the limiting through groove 21, and the snap-fit ​​groove 131 and the snap-fit ​​post 23 snap together. The snap-fit ​​block 13 is located at the bottom of the connector body 1 away from the plug-in block 12, so that the snap-fit ​​block 13, the limiting insert block 11, and the plug-in block 12 are in a straight line. During the installation of the connector body 1 on the connecting base 2, the connector body 1 is first tilted so that the plug-in block 12 extends through the limiting through groove 21 into the receiving groove 22. Then, the connector body 1 is rotated so that the snap-fit ​​groove 131 of the snap-fit ​​block 13 and the snap-fit ​​post 23 of the connecting base 2 snap-fit ​​into each other and fix them in place. This fixes the connector body 1 and the connecting base 2 together, making it easy to disassemble and assemble, and improving the stability of the connection between the connecting base 2 and the connector body 1.

[0030] To facilitate the complete insertion of the plug-in block 12 into the receiving groove 22 during rotation, the upper surface of the plug-in block 12 is arc-shaped at the connection with the limiting insert 11, and the connection between the limiting through groove 21 and the groove wall of the receiving groove 22 is arc-shaped. Furthermore, the arc angle between the plug-in block 12 and the limiting insert 11 is consistent with the arc angle between the limiting through groove 21 and the groove wall of the receiving groove 22.

[0031] Meanwhile, to improve the lateral stability between the connecting base 2 and the connector body 1, the widths of the limiting insert 11, the snap-fit ​​block 13, and the plug-in block 12 are all equal to the width of the limiting through groove 21. The limiting through groove 21 can limit and fix the limiting insert 11.

[0032] The snap-fit ​​groove 131 is an arc groove, and the snap-fit ​​post 23 is a circular post. The groove opening of the snap-fit ​​groove 131 is notched outwards. The notched groove opening of the snap-fit ​​groove 131 facilitates the snap-fit ​​of the circular post into the arc groove, thereby facilitating the assembly and disassembly of the connector body 1 and the connecting base 2.

[0033] Reference Figure 1 and Figure 3 Both sides of the bottom of the connector body 1 are provided with downward-facing limit blocks 14, which are in contact with the upper sidewall of the connecting base 2. The limit blocks 14 are inclined outwards towards the lower sidewall of the connecting base 2 and have guide slopes 141. The sidewall of the connecting base 2 has mating slopes 24 that are adapted to the guide slopes 141. The limit blocks 14 on both sides of the bottom of the connector body 1 are in contact with the sidewall of the connecting base 2, thus further limiting the connecting base 2 and improving the stability between the connector body 1 and the connecting base 2. Simultaneously, the guide slopes 141 on the lower sidewall of the limit blocks 14 facilitate the insertion of the snap-fit ​​block 13, the limit insert block 11, and the plug-in block 12 at the bottom of the connector body 1 into the limit through groove 21. The mating slopes 24 on the sidewall of the connecting base 2, which are adapted to the guide slopes 141, further enhance the stability between the connecting base 2 and the connector body 1, thereby improving the stability of the wiper during its swing and improving the quality of the wiper.

[0034] This application also discloses a windshield wiper, as shown in the embodiments below. Figure 4 The windshield wiper includes a wiper connector and a wiper blade 3, which is mounted on the bottom of the connecting base 2.

[0035] The implementation principle of the wiper connector and wiper in this application embodiment is as follows: the connector body 1 is connected to the wiper arm, while the connecting base 2 is installed and fixed to the wiper blade. The connector body 1 is mutually fixed with the receiving groove 22 and the locking post 23 on the connecting base 2 through the locking groove 131 in the bottom plug block 12 and locking block 13, thereby realizing the quick disassembly and assembly of the connector body 1 and the connecting base 2. Thus, when the wiper needs to be replaced, only the wiper blade and the connecting base 2 need to be replaced, thereby reducing the cost of wiper replacement.
