Abstract
The utility model provides a golden finger connecting device which comprises an upper clamp plate, a lower clamp plate and a rubber mat which is placed on the inner surface of the lower clamp plate. The rubber mat is provided with a plurality of electricity conduction bars which can respectively correspond to connecting electrodes of a golden finger. A protection layer which can prevent abrasion to the connecting electrodes is arranged on the inner surface of the upper clamp plate. The surface of the rubber mat is a protruding cambered surface. Clamp baffles which can limit the golden finger are arranged on two sides of the lower clamp plate. When the golden finger connecting device is used, the golden finger of a liquid crystal display to be detected is placed on the lower clamp plate, the upper clamp plate is placed on the golden finger of the liquid crystal display, the electricity conduction bars are enabled to be in one-to-one correspondence with the connecting electrodes of the golden finger, the upper clamp plate presses the golden finger downward to enable the electricity conduction bars to be closely connected with and sufficiently contact the golden finger of the liquid crystal display, and therefore detection signal of detection equipment can be well input to the liquid crystal display through the electricity conduction bars for detection, and the effect that the abrasion to the connecting electrodes of the golden finger is avoided is achieved.
Description
Technical field
The utility model belongs to liquid crystal display production testing field, relates in particular to the checkout equipment field of liquid crystal display.
Background technology
LCDs has been brought convenient and practical in the application of every aspect to people, because the characteristic that liquid crystal display 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 certified products 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 inside 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 inside surface is provided with the protective seam that can prevent the wearing and tearing of described connecting electrode, and 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 the card shelves.
Preferably, described card shelves are 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 that needs are detected places on the described lower plate; because the both sides of described lower plate are provided with the card shelves; described golden finger is inserted between the card shelves; 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; 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; thereby the detection signal with checkout equipment that can be good is input in the liquid crystal display by described bus and detects; because the physical characteristics 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 seam at described lower plate inside surface, further avoided golden finger connecting electrode lower surface to be worn.
