Abstract: A crimping tool with detachable cable connector tester includes a crimper body for crimping a signal connector to a cable, two pressing handles, and at least one cable connector tester. Therein, the two pressing handles are movably connected with the crimper body and have at least one fastening groove, the cable connector tester is detachably set in the fastening groove, and thereby construction workers can use the crimping tool to crimp the signal connector with the cable. After crimping, the signal connector can be inserted into the cable connector tester that is selectively attached with the crimping tool, so as to test the conduction between the signal connector and the cable.

Abstract: An improved structure of a network wire tester is disclosed. The improved structure of a network wire tester includes a primary device and a secondary device installed with respective network receptacles. The bottom of the primary device is left with a concave container, Two sides of the container are installed with respect long holes and buckle grooves. The two sides of the secondary device are formed with suspending elastic pressing buckles. Each of the elastic pressing buckle is installed with a hook and a protruded pressing key so that the primary device and the secondary device can be assembled to the two ends of a network wire to be tested so to detect the transmission quality. When they are not used, the secondary device is pushed into the container of the primary device to be hidden therein by the elastic pressing buckles to buckle the buckle grooves. Thus, the primary device and the secondary device are combined together and the space is used efficiently.

Abstract: A data transfer switch has a casing and a linking unit which is rotatably provided inside the casing and which includes a plurality of interconnected linking pieces. Each of the linking pieces is a relatively thin cylindrical insulator and has one side which is provided with an axial tubular projection that extends toward an adjacent one of the linking pieces so as to form an annular groove between each of the linking pieces and the adjacent one of the linking pieces. A plurality of connector pin sets are mounted on a side wall of the casing. Each of the connector pin sets has a plurality of connector pins which respectively extend into a corresponding annular groove of the linking unit. A conductive pattern is provided on each of the linking pieces at each annular groove.
