The present invention relates to a vehicle wiper connector that can prevent shaking.

In general, when a glass surface is contaminated due to dust or weather conditions in the air, the view is blurred, which hinders safe driving. Thus, a wiper device is installed to wipe the glass surface to secure a watch for a driver's safe driving.

A general wiper is installed on one side of a vehicle as shown in FIG. 1 and is rotated left and right by a driving motor, and a wiper strip (Wiper) mounted on the arm and moved in close contact with a glass surface to wipe the glass surface. strip).

Here, the wiper strip further comprises a configuration of the bracket (Bracket) and the adapter (Adapter) for coupling with the arm, in particular, although not shown in detail in the drawing is coupled to the rubber wiper strip in contact with the glass surface to give elasticity The wiper strip and the tension spring is connected to the plurality of link members in a state including a tension spring.

Such a general wiper is operated to remove foreign substances on the vehicle glass surface while turning the wiper (R1) in the left and right directions as shown in FIG. 1 (a). Likewise, the load (P) acts on the arm to press the wiper to operate the wiper.

On the other hand, since the curvature of the vehicle glass surface is formed differently according to the position as shown in (a) and (b) of FIG. 1, the wiper strip must be rotated (R2) about the bracket as shown in (b) of FIG. The foreign matter on the glass surface of the vehicle can be smoothly removed.

Of course, even when the coupling groove 11 of the adapter 10 is formed in a circular shape as described above, deformation occurs at the coupling portion between the adapter 10 and the spindle shaft 30 when pressing force and centrifugal force generated in the arm 1 are generated. However, the present invention is to act so as not to interfere with the rotation of the bracket 20 because the spindle shaft 30 and the bracket 20 to maintain a state that can always rotate.

In particular, even if the adapter 10 according to the present invention further forms the guide groove 11a in the coupling groove 11 as in the related art, the removal means S coupled to the bracket 20 may freely rotate according to the curvature of the vehicle glass surface. To work.

Meanwhile, in the present invention, the spindle shaft 30 may be variously formed to obtain additional effects.

That is, when the side fixing jaw 32 is formed at one end or both ends of the spindle shaft 30 in the present invention as shown in Figs. 11 (b) to 11 (d), it is possible to operate the arm 1. When the wiper is turned to remove foreign substances on the glass surface of the vehicle, the gap between the vertical walls 22 formed on the bracket 20 and the phenomenon of being damaged may be minimized.

In addition, when the auxiliary fixing jaw 33 is formed on the spindle shaft 30, the same effect as that of the side fixing jaw 32 can be manufactured in a beautiful appearance.

In particular, the secondary spindle shaft coupling hole 24 having a larger diameter than the spindle coupling hole 23 in the spindle coupling hole 23 of the bracket 20 that engages the spindle shaft 30 as shown in FIG. If you form more will be able to form a more beautiful appearance.
