[0153] Example 2

[0154] This embodiment is a supplementary embodiment of Embodiment 1.

[0155] like Figure 8 As shown, the wiper connector mounting structure 100 further includes a positioning unit 160 . The positioning unit 160 is disposed on the top of the base unit 110 and is limitedly connected to the second connecting unit 130 to limit the relative position of the first connecting unit 120 and the second connecting unit 130 .

[0156] Specifically, the positioning unit 160 is disposed on the top of the base element 111 and is position-limitingly connected to the second connecting element 131 .

[0157] In some of the embodiments, the positioning unit 160 is integrally formed with the base element 111 .

[0158] The size of the positioning unit 160 matches the size of the first connecting element 121. Generally, the radial size (such as width) of the positioning unit 160 is smaller than the distance between the two first connecting elements 121.

[0159] In some embodiments, the cross section of the positioning unit 160 is L-shaped. Specifically, the positioning unit 160 includes a longitudinal positioning element and a transverse positioning element. The longitudinal positioning element is disposed on the top of the base element 111, and the side of the longitudinal positioning element is flush with the side of the first connecting element 121; the transverse positioning element is disposed on the top of the longitudinal positioning element and is slidably connected to the second connecting element 131.

[0160] The size of the longitudinal positioning element matches the size of the second connecting element 131. Generally, the height of the longitudinal positioning element is equal to the thickness of the second connecting element 131.

[0161] In some of the embodiments, the positioning unit 160 is a limiting buckle.

[0162] The advantage of this embodiment is that, by arranging a positioning unit on the top of the base unit, the second connection unit can be quickly aligned with the first connection unit, thereby saving alignment time and improving installation efficiency.
