Description

Wiper Connector Assembly

The present invention relates to a wiper connector for use in a vehicle and an assembly using such a wiper connector.

In order to clean the window of a vehicle, the wiper assembly which connects the wiper blade assembly which adheres to a glass window to the wiper arm which can reciprocate is used. Connecting the wiper blade assembly to the wiper arm requires a wiper connector sandwiched between the two parts.

Recently, flat blade wipers without primary yokes and secondary yokes of wipers have been widely used. The flat blade wiper is provided inside the blade and has an initial curvature by a support member having an initial curvature. When the flat blade wiper comes into contact with the windshield of the vehicle, the flat blade wiper is brought into close contact with the windshield by a restoring force.

In such a flat blade wiper, a wiper connecting device is used to connect the wiper arm driven by the drive means and the wiper blade. In the general wiper in which the primary yoke is used, the wiper connector can be disposed inside the primary yoke, so that the end of the wiper arm is naturally covered by the primary yoke, so the aesthetic problem is not large. However, in a flat blade wiper without a primary yoke, the wiper arm end is exposed when only the wiper connector is provided, which also has an aesthetic disadvantage. Therefore, the guide cap member which can cover the end part of a wiper arm with respect to a wiper connector is widely used for a flat blade wiper.

In the early stages, a structure in which the end portion of the U-hook wiper arm was coupled to the curved front end of the wiper connector was widely used. It is a structure in which a flat blade wiper secures a frame in which the shaft is riveted to the support member of the wiper, rotatably mounts the connector to the shaft of the frame, and fastens the U hook-type wiper arm to the connector. In recent years, however, in addition to the U-Lock type structure, a structure in which the wiper arm slides toward the wiper connector (M-Lock type) or approaches from the upper side and is coupled (Top-Lock type) has been increasingly adopted. The structure of the wiper connector is different depending on the manner of coupling, thus there is a lot of inconvenience because there is no compatibility of the wiper connector.

  That is, in the related art, by fixing and fastening the wiper arm and the blade by using various coupling type connectors to fix the blade and the arm, there is an inconvenience of increasing the cost and changing the connector that can be used according to the shape of the wiper arm. .

It is an object of the present invention to solve the problems of the prior art by proposing a multifunctional connector technology that enables the coupling of various types of wiper arms with one connector.

The vehicle wiper connector assembly according to the present invention includes a U-hook wiper arm 320, a top lock type wiper arm 310 provided with a protrusion 314 at the front end of the upper surface and a coupling part 313 provided at the side.
