Abstract

The utility model provides a gold finger connecting device, comprising an upper clamping plate, a lower clamping plate and a rubber pad arranged inside the inner surface of the lower clamping plate, wherein the rubber pad is provided with a plurality of conductive bars corresponding to the connection electrodes of the gold fingers respectively, and the inner surface of the upper clamping plate is provided with a protection layer for preventing the connection electrodes from being worn. In the process of use, the gold fingers of a liquid crystal display screen to be detected are arranged on the lower clamping plate, the upper clamping plate is arranged above the gold fingers of the liquid crystal display screen, the conductive bars are corresponding to the connection electrodes of the gold fingers one to one, the conductive bars are connected with a detective device through cables, and the upper clamping plate presses downwards the gold fingers and enables the conductive bars to be closely connected and fully contacted with the gold fingers of the liquid crystal display screen, thereby excellently inputting the detection signal of the detection device into the liquid crystal display screen through the conductive bars for detection; and the inner surface of the upper clamping plate is added with the protection layer, thereby further preventing the upper surface of the connection electrodes of the gold fingers from being worn.

Description

A kind of gold finger connection device

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, and described train wheel bridge inner surface is provided with the protective layer that can prevent described connecting electrode wearing and tearing.

Preferably, described rubber cushion surface is the cambered surface design of projection.

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; 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 train wheel bridge inner surface, further avoided golden finger connecting electrode upper surface to be worn.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

Shown in seeing figures.1.and.2; the utility model embodiment provides a kind of gold finger connection device; comprise train wheel bridge 1 and lower plate 2; and the rubber cushion 21 that places described lower plate 2 inner surfaces; described rubber cushion 21 has a plurality of buss that can be corresponding with the connecting electrode difference of golden finger 31; described train wheel bridge 1 inner surface is provided with the protective layer 11 that can prevent described connecting electrode wearing and tearing; use technique scheme; gold finger connection device provided by the utility model in use; the golden finger 31 of the liquid crystal display screen 3 that needs are detected places on the described lower plate 2; described train wheel bridge 1 places golden finger 31 tops of described liquid crystal display screen 3; and make described bus corresponding one by one with the connecting electrode of described golden finger 31; described bus is connected with checkout equipment by cable; 1 pair of described golden finger 31 of described train wheel bridge presses down; impel described bus closely to be connected fully contact with the golden finger 31 of liquid crystal display screen 3; thereby the detection signal with checkout equipment that can be good is input in the liquid crystal display screen 3 by described bus and detects; because the physical characteristic of described rubber cushion 21 own; when being subject to the downforce of described train wheel bridge 1; slight deformation can occur in described rubber cushion 21; can guarantee that described bus closely is connected fully contact with the connecting electrode of golden finger 31; owing to increased protective layer 11 at described train wheel bridge 1 inner surface, further avoided the connecting electrode upper surface of golden finger 31 to be worn.

Further, for the connecting electrode that can make golden finger 31 fully contacts with described bus, described rubber cushion 21 surfaces are the cambered surface design of projection, the described rubber cushion 21 rear generation slight deformation that is under pressure, and the rubber cushion 21 of radian design is connecting electrode better.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
