Abstract
The utility model provides a golden finger connecting device, which comprises an upper clamping plate, a lower clamping plate and a rubber pad arranged on the inner surface of the lower clamping plate. The rubber pad comprises a plurality of bus bars respectively corresponding to the connection electrodes of a golden finger. The inner surface of the upper clamping plate is provided with a protective layer preventing the connection electrodes from being worn. A projecting cambered face is designed on the surface of the rubber pad. The two sides of the lower clamping plate are provided with stoppers for limiting the golden finger. When the golden finger connecting device is in use, the golden finger of a liquid crystal screen to be detected is placed on the lower clamping plate. The upper clamping plate is placed above the golden finger of the liquid crystal screen. The bus bars and the connection electrodes of the golden finger are corresponding one by one. The upper clamping plate presses the golden finger downwards to make the bus bars and the golden finger of the liquid crystal screen tightly connected and fully contacted. Detection signals of a detection apparatus can be well input into the liquid crystal screen through the bus bars for further detection. The connection electrodes of the golden finger are thus prevented from being worn.
Description
Technical field
The utility model belongs to liquid crystal display screen production testing field, relates in particular to the checkout equipment field of liquid crystal display screen.
Background technology
LCDs has been brought convenient and practical in the application of every aspect to people, because the characteristic that liquid crystal display screen itself has, LCDs needs necessary detecting step to guarantee its qualification rate in process of production, adopt card inserting-in mode to carry out to the testing of LCDs in the prior art, so-called card inserting-in mode is the link slot that the stud connector design of checkout equipment is become insertion slot type, the connecting electrode of the LCDs that need are detected inserts in the link slot, then by checkout equipment LCDs is detected, be provided with a plurality of connection shell fragments corresponding with the connecting electrode of LCDs in the link slot, display screen enters in the link slot, described connection shell fragment has downward pressure, force the connection shell fragment closely to be connected with each electrode points of connecting electrode respectively, detect complete afterwards LCDs the taking-up from link slot, the link slot of this type of checkout equipment has three shortcomings:
The connecting electrode of 1 LCDs is subject to the wearing and tearing of at least twice connection shell fragment, because the coating of connecting electrode is very thin, come off easily afterwards frayed, no problem during detection, but coming off of coating causes display screen to become a problem display screen that is labeled as qualified product easily when extracting connecting electrode;
2 testing processes also can consist of wearing and tearing to connecting shell fragment, connect the phenomenon that the electrode coating on the shell fragment also can come off after long-term the use, cause easily testing result mistake to occur, it is not enough that shell fragment elastic force also occurs in addition easily, connects to occur virtually connecting the testing result mistake to occur equally;
3 link slots have a plurality of connection shell fragments, and its production cost is higher, have again above-mentioned problem at the 2nd simultaneously, and after problem having occurred, its replacement cost is high, the whole production cost that can improve LCDs.
The utility model content
The purpose of this utility model is to provide a kind of gold finger connection device, and the connecting electrode that is intended to solve LCDs in the prior art is subject to the problem of the link slot wearing and tearing of checkout equipment easily.
The utility model is to realize like this; a kind of gold finger connection device; comprise train wheel bridge and lower plate; and the rubber cushion that places described lower plate inner surface; described rubber cushion has a plurality of buss that can be corresponding with the connecting electrode difference of golden finger; described train wheel bridge inner surface is provided with the protective layer that can prevent described connecting electrode wearing and tearing; described rubber cushion surface is the cambered surface design of projection; described lower plate both sides be provided with can be spacing to described golden finger block; the middle part of the middle part of described train wheel bridge Width and lower plate Width is flexibly connected by axis, and any side of described train wheel bridge and lower plate connecting portion has a flexible member that can make train wheel bridge and lower plate closure.
Preferably, described block is provided with the guide end that can make things convenient for described golden finger to insert.
Use technique scheme; gold finger connection device provided by the utility model in use; the golden finger of the liquid crystal display screen that needs are detected places on the described lower plate; because the both sides of described lower plate are provided with block; described golden finger is inserted between the block; make things convenient for the connecting electrode on the golden finger corresponding with described bus; described train wheel bridge places the golden finger top of described liquid crystal display screen; and make described bus corresponding one by one with the connecting electrode of described golden finger; described bus is connected with checkout equipment by cable; described train wheel bridge presses down described golden finger; impel described bus closely to be connected fully contact with the golden finger of liquid crystal display screen; thereby the detection signal with checkout equipment that can be good is input in the liquid crystal display screen by described bus and detects; because the physical characteristic of described rubber cushion own; when being subject to the downforce of described train wheel bridge; slight deformation can occur in described rubber cushion; can guarantee that described bus closely is connected fully contact with the connecting electrode of golden finger; owing to increased protective layer at described lower plate inner surface; further avoided golden finger connecting electrode lower surface to be worn; the middle part of the middle part of described train wheel bridge Width and lower plate Width is flexibly connected by axis; any side of described train wheel bridge and lower plate connecting portion has a flexible member that can make train wheel bridge and lower plate closure; described flexible member adopts spring or metal clips; the combination of described axis and flexible member is made as Flexible clamp with described train wheel bridge and lower plate; exert pressure to the end with flexible member; open the end that lower plate has protective layer and rubber cushion; after inserting described golden finger; upper lower plate is the described golden finger of closed clamping under the effect of flexible member, more convenient operation.
