Description

FPC opens a way and tests keysets

Technical Field

The utility model relates to a FPC tests technical field, specifically is a FPC opens a way test keysets.

Background

With the continuous development of liquid crystal display technology, the application field of liquid crystal display screens is also continuously widened. Pulled by the market of liquid crystal display screens and the FPC industry, the liquid crystal display screen presents a splendid scene. Many mobile phones are designed, and due to limited space of a main board, a display screen FPC is used as a connecting mechanism of the main board and peripheral devices such as a microphone and a receiver, and a connector is used for plugging on the main board. Therefore, the space is saved, the screen interference is reduced, and in order to produce a high-quality liquid crystal display module, the open circuit test needs to be carried out on the FPC of each batch before production, and then the FOG binding is carried out. FPC manufacturers use flying pins for testing, and cannot use equipment for detection due to cost consideration when a client terminal is used. A simple and efficient method is needed for sampling test so as to prevent the defective products from flowing out. And because the number of the golden finger pins of each FPC product is different, each FPC product needs to be manufactured again by a technician, the workload is increased, and the error rate is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of existence among the prior art, provide a FPC opens a way and tests keysets, thereby solved among the prior art FPC's the detection of opening a way because pin quantity difference on every FPC is different and need the measuring signal difference and need change detection device and reduced work efficiency's problem.

In order to realize the purpose, the utility model discloses a technical scheme be:

the utility model provides a FPC opens a way test keysets, includes FPC circuit board, keysets and the LED display device that awaits measuring, its characterized in that, be equipped with the golden finger on the FPC circuit board that awaits measuring, be equipped with the golden finger pin on the golden finger, fixed mounting has the connector on the keysets, be furnished with a plurality of connector pins on the connector, golden finger pin and connector pin phase-match, still be equipped with the power on the keysets, be equipped with a plurality of LED lamps, every on the LED display device the LED lamp and connector pin one-to-one, keysets and LED display device electric connection.

Preferably, the adapter plate is 80mm long and 60 mm wide, and is made of green epoxy resin PCB board.

Preferably, the adapter plate is fixedly provided with a connector in a welding mode.

Preferably, the connector pins are provided with through contact pins and signal test point pins.

Preferably, the signal test point pin is connected with a wire, and the other end of the wire is respectively connected with the power supply and an LED lamp wiring terminal corresponding to the LED display device.

The utility model discloses possess beneficial effect: the utility model discloses a connector is installed on the keysets through designing the keysets, when needing to measure the FPC circuit board of different models, only need to exchange corresponding connector, has improved certain commonality; the utility model discloses a connector pin divide into direct contact pin and signal test point pin, so can be as required the side measurement signal to avoid the FPC of same model to be different with trading the connector because of measuring signal's requirement.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: 1. the FPC board to be tested comprises 2 portions of golden fingers, 3 portions of golden finger pins, 4 portions of adapter plates, 5 portions of connectors, 6 portions of connector pins, 7 portions of power supplies, 8 portions of LED display devices, 9 portions of LED lamps.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The FPC open circuit test adapter plate is characterized in that a golden finger 2 is arranged on the FPC circuit board 1 to be tested, golden finger pins 3 are arranged on the golden finger 2, a connector 5 is fixedly mounted on the adapter plate 4, a plurality of connector pins 6 are arranged on the connector 5, the golden finger pins 3 are matched with the connector pins 6, a power supply 7 is further arranged on the adapter plate 4, a plurality of LED lamps 9 are arranged on the LED display device 8, each LED lamp 9 corresponds to one connector pin 6, and the adapter plate 4 is electrically connected with the LED display device 8.

Preferably, the interposer 4 has a length of 80mm and a width of 60 mm, and the interposer 4 is made of a green epoxy PCB. And the adapter plate 4 is fixedly provided with a connector 5 in a welding mode. The connector pin 6 is provided with a through contact pin and a signal test point pin. And the signal test point pin is connected with a lead, and the other end of the lead is respectively connected with the power supply 7 and an LED lamp 9 wiring terminal corresponding to the LED display device 8.
