Description

Gold finger connecting device

Technical field

The utility model belongs to the field of liquid crystal screen production and detection, in particular to the field of liquid crystal screen detection equipment.

Background technique

The application of the liquid crystal display in various aspects has brought convenience and practicality to the people. Due to the characteristics of the liquid crystal screen itself, the liquid crystal display screen needs necessary detection steps in the production process to ensure the pass rate, and the liquid crystal display in the prior art The detection work is carried out in a card insertion mode. The so-called card insertion mode is to design the connection member of the detection device into a slot type connection slot, insert the connection electrode of the liquid crystal display to be detected into the connection slot, and then pass the detection device to the liquid crystal. The display screen is detected, and a plurality of connecting elastic pieces corresponding to the connecting electrodes of the liquid crystal display are arranged in the connecting groove, and the display screen enters the connecting groove, and the connecting elastic piece has a downward pressure, forcing the connecting elastic pieces to respectively connect with the connecting electrodes The electrodes are tightly connected, and the liquid crystal display is removed from the connection slot after the detection. The connection slot of such a detection device has three disadvantages:

1 The connecting electrode of the liquid crystal display panel is subjected to the wear of the connecting elastic piece at least twice. Since the plating layer of the connecting electrode is very thin, it is easy to fall off after being worn, and there is no problem in the detection, but the peeling of the plating layer when the connecting electrode is pulled out is easy to cause the display screen Become a problem display marked as a good product;

2 The detection process will also cause wear on the connecting elastic piece. The electrode coating on the connecting elastic piece will also fall off after long-term use, which may lead to errors in the detection result. In addition, the elastic force of the elastic piece is also likely to occur, and the virtual connection of the connection also appears. The test result is incorrect;

3 The connecting groove has a plurality of connecting elastic pieces, which has high production cost and at the same time has the problem of the second point mentioned above. After the problem occurs, the replacement cost is high, and the production cost of the liquid crystal display is improved as a whole.

technical problem

The purpose of the present invention is to provide a gold finger connecting device, which aims to solve the problem that the connecting electrode of the liquid crystal display panel in the prior art is easily worn by the connecting groove of the detecting device.

Technical solution

The utility model is realized as follows, a gold finger connecting device comprises an upper clamping plate and a lower clamping plate, and a rubber pad placed on the inner surface of the upper clamping plate, the rubber pad having a plurality of connecting electrodes with the gold finger respectively Corresponding conductive strips.

Preferably, the surface of the pad has a convex curved surface design.

Beneficial effect

According to the above technical solution, when the gold finger connecting device provided by the present invention is used, the gold finger of the liquid crystal screen to be detected is placed on the lower clamping plate, and the upper clamping plate is placed on the gold finger of the liquid crystal screen. Upper, and the conductive strips are in one-to-one correspondence with the connection electrodes of the gold fingers, the conductive strips are connected to the detecting device through a cable, and the upper clamping plate presses the gold fingers to urge the conductive strips The gold finger of the liquid crystal screen is in close contact with the gold finger, and the detection signal of the detecting device can be well input into the liquid crystal screen through the conductive strip for detection, and the physical property of the rubber pad is received by the upper splint. When the pressure is under pressure, the rubber pad may be slightly deformed to ensure that the conductive strip is in close contact with the connecting electrode of the gold finger, and the effect of preventing the gold finger connecting electrode from being worn is achieved.

Embodiments of the invention

In order to make the objects, technical solutions and advantages of the present invention more comprehensible, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIG. 1 and FIG. 2, an embodiment of the present invention provides a gold finger connecting device, comprising an upper clamping plate 1 and a lower clamping plate 2, and a rubber pad 11 disposed on an inner surface of the upper clamping plate 1, the rubber pad 11 has a plurality of conductive strips respectively corresponding to the connection electrodes of the gold fingers 31. According to the above technical solution, when the gold finger connection device provided by the present invention is used, the gold finger 31 of the liquid crystal panel 3 to be detected is used. And disposed on the lower clamping plate 2, the upper clamping plate 1 is placed above the gold finger 31 of the liquid crystal panel 3, and the conductive strips are in one-to-one correspondence with the connecting electrodes of the gold fingers 31, the conductive strips The upper splint 1 is connected to the detecting device, and the upper cleat 1 presses down the gold finger 31 to ensure that the conductive strip is in close contact with the gold finger 31 of the liquid crystal panel 3, and the detection signal of the detecting device can be well passed. The conductive strip is input into the liquid crystal panel 3 for detection. Due to the physical properties of the rubber pad 11, the rubber pad 11 may be slightly deformed when subjected to the downward pressure of the upper cleat 1 to ensure that the pad 11 is slightly deformed. Conductive strip and gold finger 3 The connecting electrodes of 1 are in close contact with each other, and the effect of avoiding the wear of the connecting electrodes of the gold fingers 31 is achieved.
