Adjust the assembly to realize the adjustment of the distance between the upper splint and the lower splint and the adjustment of the clamping force. There is also a locking assembly for locking the upper splint and the lower splint between the upper splint and the lower splint. The upper splint or the lower splint is connected. There is the terminal clamp assembly, the lower part of the terminal clamp assembly is connected to the ground assembly, and the present invention can conveniently and accurately clamp the upper splint and the lower splint by using gears and racks to cooperate, so as to realize the connection of electric wires to the upper splint and the lower splint Between, improve the reliability and stability of the wiring, the constructor can connect the wire between the upper splint and the lower splint according to the actual needs, or choose to clamp it in the wiring clamp assembly, by rotating the force nut, you can Realize fast insertion and tightening of pins.

The invention discloses a three-station isolating switch which comprises a rack, disconnecting links, fixed contacts, grounding contacts and an operating mechanism. The rack is connected with a rotating shaft in a pivotal mode, and the rotating shaft drives the disconnecting links to rotate through first connecting levers and insulating pull rods. The operating mechanism comprises a shell, the shell is connected with a first operating shaft and a second operating shaft in a pivotal mode, and the first operating shaft is fixedly connected with the rotating shaft. The first operating shaft is fixedly connected with a first gear and an isolating limiting plate. The isolating limiting plate is provided with a first positioning hinge pin in a penetrating mode, and the two ends of the first position hinge pin are connected with the first operating shaft through two tension springs. The shell is provided with a switching-on groove, a switching-off groove and grounding grooves which are matched with the first positioning hinge pin. The second operating shaft is fixedly connected with a second gear and a connecting lever, wherein the connecting lever is connected with the shell through a second positioning hinge pin and a compression spring. The shell is provided with a second arc hole which is matched with the second positioning hinge pin. The second gear is not matched with the first gear in a switching-on state and a switching-off state and is matched with the first gear in a grounding state. The three-station isolating switch is compact in structure, reliable in action and convenient to maintain.

The invention provides a touch display device which comprises a thin-film transistor substrate, a color filter substrate and a liquid crystal layer disposed between the two. The thin-film transistor substrate comprises multiple scanning lines parallel to one another and multiple data lines parallel to one another; the scanning lines and the data lines are in insulated perpendicular intersection to define multiple pixel units. The color filter substrate comprises a screening layer which consists of multiple screening units; the screening units are in matrix arrangement and correspond to display areas of the pixel units respectively; each screening unit covers the display area of one corresponding pixel unit but exposes the scanning lines and the data lines. The touch display device has high touch sensitivity.

The invention relates to an isolated earth switch and belongs to the technical field of high-voltage power transmission. The isolated earth switch comprises a metal shell, an isolating switch, an earth switch I, an earth switch II and the like, wherein the isolating switch comprises a body embedding member, a disk-shaped insulator, a fixed-side conductor, an isolating switch fixed contact, a rack movable touch rod, a gear and a movable-side conductor; the two earth switches include disc-shaped insulator body embedding members, movable-side conductors, earth switch fixed contacts, earth switch movable contacts, earth switch movable contact shielding cases, earthing terminals, earthing shells and insulating basins. The isolated earth switch has the characteristics of simple and compact structure, high reliability and the like, is capable of earthing the buses at the two sides of breaks of the isolating switch safely and synchronously, reducing the problem of serious abrasion of the contacts when the isolating switch and the earth switches are switched on and switched off, achieving steady and reliable motion of the movable contacts of the isolating switches and rapid and convenient earthing of the movable contacts of the earth switches, and is suitable for popularization and application.
