The invention discloses a hard disk data interface pitch conversion connector, which includes a main body rubber core, a hard disk contact terminal, an FFC transfer terminal, a PCB board and a cover body. The PCB board is connected to the main body rubber core through a plurality of hard disk contact terminals. An FFC transfer terminal is also provided between the PCB board and the main body rubber core, and an FFC is connected to the FFC transfer terminal; a cover is provided on the outside of the PCB board, and the cover is connected to the main body rubber core; The FFC transfer terminal includes a first socket, a second socket, a first connecting body and a second connecting body, the first connecting body is connected to the PCB board, the second connecting body is connected to the main rubber core, and the The first socket and the second socket are distributed on both sides of the PCB, and the first FFC and the second FFC are respectively connected to the first socket and the second socket. In the present invention, an FFC transfer terminal is arranged between the PCB board and the main rubber core, so that the FFC can be directly inserted into the socket of the FFC transfer terminal, which is very convenient to plug and unplug, and replaces the original welding method.

The invention provides a folding display device. The folding display device is provided with a first display screen with a first connecting portion and a second display screen with a second connectingportion. The first connecting portion and the second connecting portion are provided with binding circuits electrically connected with display circuits on the first display screen and the second display screen respectively, the first connecting portion and the second connecting portion are connected through a bent portion with a connecting circuit, the connecting circuit is electrically connectedwith the binding circuits on the first and second connecting portions, and signal connection between the first display screen and the second display screen is achieved. Compared with the prior art that flexible display devices are directly folded, the thickness of the bent portion can be greatly lowered, the folding display device has the small bent curvature radius, the foldability is enhanced,the good reliability can be still achieved after repeated bending, and the product quality is improved.

The invention relates to a universal metering test interface adapter. The universal metering test interface adapter comprises an adapting cable, a uniformization test interface, a switch matrix, standard test interfaces and a power source. An input end of the uniformization test interface is connected with an external tested device through the adapting cable, and an output end of the same is connected with an input end of the switch matrix and used for accessing tested signals into the adapter. An input end of the switch matrix is connected with the uniformization test interface, and an output end of the switch matrix is connected with the standard test interfaces and used for being respectively connected with the corresponding standard test interfaces according to signal types of the tested signals. The standard test interfaces are connected with an external calibrating device and used for accessing the tested signals into the external calibrating device. The power source is connected with the switch matrix and used for supplying power for the switch matrix. The universal metering test interface adapter has higher universality and convenience in operation, signal connection can be realized only by changing the adapting cable for different non-standard test interfaces, and needs of manufacturing other test modules and opening a machine case to replace the modules are omitted.
