Description

Connector, connector assembly and windshield wiper adapted to wiper arm of sliding cover type windshield wiper

Technical Field

The invention relates to a windshield wiper component, in particular to a connector which is adaptive to a sliding type windshield wiper arm, a connector assembly and a windshield wiper comprising the connector assembly.

Background

The fraio system company filed an invention patent of "an adapter for a windshield wiper of a motor vehicle and an assembly of the adapter" on 2016, 6, 27.78, patent publication No. CN106274819A, which discloses a wiper arm of a sliding cover type, and the specific structure of which can be referred to; meanwhile, the invention patent also discloses an adapter (wiper connector) 1226 matched with the sliding type wiper arm, as shown in fig. 1-4, the adapter 1226 has a front cover 1294 with a hollow top cover and a rear body 1298, the rear body 1298 has fingers 1299, according to the patent document, the matching mode of the adapter 1226 and the wiper arm is as follows: a cover 30 is positioned over the adapter and is ready to be inserted into space 1296 by passing through opening 1294c in enclosure 1294. The lid 30 is then linearly moved longitudinally until it is inserted into the space 1296 with the front end wall of the lid in contact with the front wall 1294a of the enclosure (fig. 3). The cover 30 then moves with the arm causing it to pivot about a transverse axis located generally at the front wall of the hood. This pivoting may be facilitated by sliding front wall 36d of cover 30 over the outer surface of front wall 1294a of enclosure 1294. This pivoting continues with the side walls of the cover 30, which are inserted into the lateral spaces 1296a, arranged on each side of the rear body 1295, which helps to correctly laterally position the arms and the cover 30 so that the complementary means of the cover 30 cooperate with the elastic snap-fastening means carried by the adapter. This pivoting forces the tabs 1298 to elastically deform laterally, moving away from each other, allowing the hooks 42cb of the rear lip 42c of the cover 30 to pass. When the hooks are positioned next to the notches 1298aa, the tabs 1298 return to their original position in the axis of the adapter sidewall, and the hooks are opposed, optionally abutting against the front face 1299a of the finger 1299. By adopting the scheme, the structure of the adapter 1226 is complex, if the front cover 1294 needs to be hollowed out, the rear body 1295 comprises a design of a protruding piece 1298 with a special-shaped structure and the like; meanwhile, when the hook 42cb of the rear lip 42c of the lid 30 is inserted into the notch 1298aa, the protruding piece 1298 needs to be elastically deformed transversely, and to ensure that the protruding piece 1298 can be finally clamped with the hook 42cb of the lid 30, the elastic cantilever of the protruding piece 1298a needs to have a certain wall thickness, so that the lid 30 needs to overcome a large resistance (elastic restoring force) to drive the protruding pieces 1298 to elastically deform away from each other, and the installation is laborious.

In view of the above, the present inventors have devised the present invention for structural redesign of the adapter.
