This utility model relates to the field of Ethernet connector technology and discloses a simple and efficient Ethernet connector with a raised dot structure. It includes a plastic shell, a connecting plate fixedly connected to the top of the plastic shell, a fixing tube fixedly connected to the rear end of the plastic shell, mounting protrusions fixedly connected to the surface of the fixing tube, an inner rounded corner fixedly connected to the top of the fixing tube, and a mounting clip fixedly connected to the front end of the inner rounded corner. This utility model modifies the clip structure of the plastic shell by adding an inner rounded corner, making the stress at the deformation point more even, simplifying the structure, and achieving a simple, efficient, and durable clip with lower mold costs. By adding a raised dot structure to the shell, the insertion and extraction force is increased, the gap is reduced, and a stable signal is achieved. This utility model avoids the hidden dangers of complex structures that are prone to breakage and insufficient insertion and extraction force, thus improving the service life of the connector.

The utility model discloses a simple printed board pulling tool in the field of pulling tool, including printed board switching support, fixed bolster, a plurality of positioning pin, pulling hand wheel, a plurality of positioning pin set up on fixed bolster, and fixed bolster is connected printed board switching support through pulling hand wheel. Through a simple printed board pulling tool, the pulling of the integrated printed board with many module interconnection quantity, many bus pins and big plug-in force is realized, the stress area is wide, the position of the pulling thread hole of the tool is adjusted according to the printed board opening position, makes it even stress, adjusts the pulling stroke through the control processing thread depth, only rotates the pulling hand wheel to realize pulling, and the operation is simple and flexible.

The application provides an elastic needle which is used in cooperation with a base, the elastic needle is assembled in a mounting hole of the base, the elastic needle comprises a needle tube, a plurality of split grooves are formed in the tube wall of the needle tube along the axial direction, the split grooves divide the tube wall of the corresponding area into a plurality of elastic arms which can produce radial elastic deformation, when the needle tube is assembled in the base mounting hole, the tube wall is in elastic contact with the inner wall of the base mounting hole through the radial elastic deformation of the elastic arms. The elastic needle of the application, the needle tube is in elastic contact with the inner wall of the base mounting hole through the elastic arms, so that the insertion and extraction force of the elastic needle in the mounting hole is increased, and the elastic needle is prevented from being loosened or popped out from the mounting hole in harsh working conditions such as vibration. Meanwhile, the split grooves are designed to make the tail part of the needle tube have radial deformation capacity, and prevent the insertion and extraction force from being too large.
