BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pinch tab type connector that can firmly and efficiently fasten a pinch tab type operating arm of a motor vehicle wiper blade.

Usually, the operation arm and the connector among the constituent members of the vehicle wiper blade device are power transmission means and coupling means for easily applying rotational power in the vehicle to the blade body, and various kinds exist according to the binding form.

"으로 절곡된 일정길이와 넓이의 양 날 개 전체가 커넥터의 몸체를 감싸면서 끼워 덮는 체결형태로 구성되어 커넥터와의 결합면적이 상당히 넓다는 특징을 가지며, 이는 커넥터와 작동아암 사이에 요구되는 견고하고 안정된 결합성에 대한 최적조건을 제공함에 따라 최근 이를 채택하는 블레이드장치가 차츰 증가하고 있다.Among them, a pinch tab type operating arm is roughly defined as disclosed in Patent Publication No. 10-2005-0085129.

"Wings of both lengths and widths bent to" are composed of a fastening type that covers the body of the connector and covers it, so that the mating area between the connector and the connector is quite large. In recent years, the number of blade devices adopting them has gradually increased as they provide optimum conditions for stable and stable bonding.

However, the structure of the conventional pinch tap type connector to which the pinch tap type operating arm is fastened is very unreasonable, so it is very difficult and difficult when fastening the operating arm to the connector or detaching / detaching as necessary. There is a significant problem, such as a case that is damaged, a new improvement structure is required.

That is, the conventional pinch tab type connector is configured to be assembled pins that can be rotated to the clamp of the blade device in the upper front side is formed with an opening and a circular projection that can be inserted into the end locking piece of the working arm and rotated while ,

The rear end is provided with a resilient action part designed to provide optimal resilience by lengthening the neck and making the neck relatively small for easy resilience of the inclined locking member protruding downward from the lower rear of the operating arm. Each end has a structure in which a locking groove is formed in which the operation arm locking member can be elastically locked.

When the pinch tab type arm is fastened, the end of the arm is turned downward while the rear end is pushed up to form a large angle of inclination. In contact with the located circular protrusion,

"으로 절곡된 작동아암의 양 날개가 커넥터의 몸체양면을 감싸면서 체결되는데,In this state, when the operation arm raised up at an upward angle flips the rear part consecutively downward, it rotates a certain radius based on the circular protrusion formed at the upper side of the connector.

The wings of the working arm bent with "are wrapped around the body of the connector,

At this time, the locking member of the working arm is elastically cleaved inward by pressing the upper and side surfaces of the locking mechanism to be locked to the locking groove formed on the elastic action of the connector. Is configured to be stuck / bound on

Such a conventional pinch tap type connector has no problem at all in normal times, but in winter, when the temperature drops below freezing, the neck has a long neck and a weak elastic action part, which is hard and does not perform smooth elasticity when given a constant pressing force. not,

When pressing the fingers of both resiliency parts of the connector to release / detach the engaged working arm from the connector, it may not be pressed well, which may cause considerable difficulty in detachment or breakage due to excessive force. It has a flaw.

In addition to the above problems, as described above, when the conventional pinch-tab type connector and the operating arm are fastened, the end of the operating arm is directed downward while the opposite rear rod portion is pushed up so as to be severely inclined. Since the rod part of the working arm cannot be tilted in such a way as it is connected to the rotating power unit, when replacing the blade by a general person, the connector is actually not tilted, but the connector is removed from the blade and the arm is Holding the end and holding the connector separated by the other hand inclined in the reverse direction to engage and strongly press fastening or holding the whole blade body including the connector to be tilted to tighten, there is a significant inconvenience and difficulty in tightening the operating arm.

Therefore, in the present invention was devised to eliminate the above problems, first, when the pinch tap-type operation arm is coupled to or detached from the wiper blade device for an automobile, it is easily and easily fastened and detached at any time without breaking or breaking under any environmental conditions. Not only is it possible, but it has been completed as a technical task with the focus on providing a new pinch-tap type connector that can maintain a more robust, complete and stable coupling state in the assembled / coupled state.

In order to achieve the above technical problem, the present invention will be described in more detail based on the accompanying drawings.
