Abstract

A wiper connector for a vehicle may be provided which connects a wiper arm to a wiper blade 10 and includes: a body 320 including a pair of elastic moving pieces 362 which is formed on one end thereof and faces each other, and one or more coupling parts 330 and 340 which are formed on both sides thereof and by which the wiper arm is caught; and a cover 310 movable to a fixing position for fixing the wiper arm which is caught by the body 320 and to a release position for releasing the fixed wiper arm. The pair of the elastic moving pieces 362 elastically restrains the movement of the cover 310 at the fixing position and allows the cover 310 to move to the release position when a releasing force for removing the elastic restraint is applied to the elastic moving piece 362.

Claims

1. A wiper connector 300 for a vehicle, which connects a wiper arm to a wiper blade 10, the wiper connector 300 comprising:

a body 320 comprising a pair of elastic moving pieces 362 which is formed on one end thereof and faces each other, and one or more coupling parts 330 and 340 which are formed on both sides thereof and by which the wiper arm is caught; and

a cover 310 movable to a fixing position for fixing the wiper arm which is caught by the body 320 and to a release position for releasing the fixed wiper arm,

wherein the pair of the elastic moving pieces 362 elastically restrains the movement of the cover 310 at the fixing position and allows the cover 310 to move to the release position when a releasing force for removing the elastic restraint is applied to the elastic moving piece 362.

2. The wiper connector for a vehicle of claim 1, wherein the cover 310 surrounds both sides of a portion of the body 320 and has an open front side thereof such that one end of the cover 310 is caught at the fixing position by the elastic moving piece 362 and the elastic moving piece 362 is located within the lower portion of the cover 310 at the release position.

3. The wiper connector for a vehicle of claim 1, wherein the elastic moving piece 362 is formed at the fixing position to contact with at least a portion of an end of the cover 310.

4. The wiper connector for a vehicle of claim 1, wherein the body 320 further comprises a coupling recess 363 formed in both sides thereof, and wherein a pair of coupling protrusions 311 formed within the cover 310 is coupled to the coupling recess 363 and guides a forward and backward movement of the cover 310.

5. The wiper connector for a vehicle of claim 4, wherein the coupling recess 363 is formed to be inclined upwardly toward a front of the connector.

6. The wiper connector for a vehicle of claim 4, wherein the body 320 further comprises a coupling guide part 364 which is formed on both sides of the body 320 and guides the coupling of the pair of the coupling protrusions 311 of the cover 310 and the coupling recess 363, and wherein the coupling of the coupling protrusion 311 and the coupling recess 363 is performed by the following process that the pair of the elastic moving pieces 362 is closer to each other, the cover 310 is rotated at a predetermined angle such that the coupling protrusion 311 is inserted into the coupling guide part 364 in accordance with the shapes of the coupling protrusion 311 and the coupling guide part 364, the coupling protrusion 311 is guided from the top to the bottom of the body 320 along the coupling guide part 364, and the cover 310 is rotated in an opposite direction to the rotation direction of the predetermined angle.

7. The wiper connector for a vehicle of claim 1, wherein the body 320 further comprises a fitting part 350 which is formed to protrude within the body 320 and is fitted and coupled to a fitting recess 211 formed approximately in the center of the wiper blade 10.

8. The wiper connector for a vehicle of claim 7, wherein the fitting part 350 slides on the fitting recess 211 from the top to the bottom of the fitting recess 211 and an upward movement of the fitting part 350 is restricted by a catching protrusion 215 formed on the fitting recess 211, so that the fitting part 350 is coupled to the fitting recess 211.

9. The wiper connector for a vehicle of claim 1, wherein a protrusion receiving recess 220 into which a lower protrusion 351 formed in a lower portion of the body 320 is inserted is formed in a central portion 210 of the wiper blade 10, wherein the central portion 210 is comprised of a pair of plate-shaped members which faces each other and protrudes parallel to each other, wherein a bottom surface of the body 320 comprises a central portion receiving recess 355 receiving the pair of the plate-shaped members, and wherein an uneven structure is formed on at least a portion of a side of the lower protrusion 351 and a side 352 of the central portion receiving recess 355.

10. The wiper connector for a vehicle of claim 9, wherein a central connection portion 214 connecting the plate-shaped members is formed between the pair of the plate-shaped members, and wherein the lower portion of the body 320 comprises a central connection recess 354 receiving the central connection portion 214.

11. The wiper connector for a vehicle of claim 9, wherein the central portion 210 comprises an opening 216 extending through the central portion 210.

12. The wiper connector for a vehicle of claim 1, wherein the wiper connector is selectively connected either to a wiper arm (ta) comprising a tap which contacts with the top surface and both sides of the wiper connector and extends toward the cover 310, or to a wiper arm (ca) comprising a cap which contacts with the top surface or side of the wiper connector.
