The application belongs to the technical field of electrical components, and particularly relates to an equipment for connecting electrical conductors, especially to an optical fiber connector shell assembling equipment and an assembling process thereof; wherein one kind of optical fiber connector shell assembling equipment comprises: a driving piece which is rotationally arranged in the working position and has a limiting groove in the middle part for limiting a ceramic ferrule; a positioning sheet which is liftably arranged on the outer wall of the driving piece and is linked with the driving piece; and at least two limiting plates which are slidingly arranged on the side wall of the positioning sheet and are used for limiting springs; wherein, after the ceramic ferrule is placed in the limiting groove, the spring manipulator sets the spring on the outer wall of the ceramic ferrule from top to bottom; the driving piece drives the positioning sheet to move downward, and the limiting plate extrudes the spring to compress, so as to expose the ceramic ferrule; the plastic upper shell is set on the outer wall of the ceramic ferrule from top to bottom, and the plastic upper shell pushes the limiting plate to shrink into the positioning sheet, so that the compressed spring is reset upward to be inserted into the plastic upper shell.

This utility model discloses a projection wallcovering, relating to the field of wallcoverings. Its key technical features include an inner layer and an outer layer. A first connector is fixedly connected to the side of the inner layer away from the wall, and a second connector is fixedly connected to the side of the outer layer near the inner layer. The second connector is detachably connected to the first connector. The weave density of the inner layer is lower than that of the outer layer. In this utility model, when projection is needed, the outer layer is fixed onto the inner layer. The outer layer has a higher weave density and is flatter, and its surface is coated with a titanium dioxide coating to improve reflectivity, ensuring the optical effect of the outer layer's side away from the wall when reflecting projected light. The inner layer has a lower weave density, and its breathability is improved by the absence of padding yarn. Combined with the breathability of the linen yarn itself, this ensures the intensity of gas exchange between the two sides of the inner layer.
