Abstract: The invention provides a positioning tool and a busbar mounting method. The positioning tool includes a first mount, a second mount, a first link, a second link and a positioning base. The first mount and the second mount are configured to be mounted on opposite sides of the server cabinet, respectively. The first link and the second link are spaced apart from each other. Opposite ends of the first link are respectively pivotally connected to the first mount and the second mount. Opposite ends of the second link are respectively pivotally connected to the first mount and the second mount. The positioning base is pivotally connected to the first link and the second link. The positioning base is located between the first mount and the second mount and is configured to position the busbar.

Abstract: A supported metallocene catalyst includes a carrier and a metallocene component. The carrier includes an inorganic oxide particle and an alkyl aluminoxane material. The inorganic oxide particle includes at least one inorganic oxide compound selected from the group consisting of an oxide of Group 3A and an oxide of Group 4A. The alkyl aluminoxane material includes an alkyl aluminoxane compound and an alkyl aluminum compound that is present in amount ranging from greater than 0.01 wt % to less than 14 wt % base on 100 wt % of the alkyl aluminoxane material. The metallocene component is supported on the carrier, and includes one of a metallocene compound containing a metal from Group 3B, a metallocene compound containing a metal from Group 4B, and a combination thereof. A method for preparing the supported metallocene catalyst and a method for preparing polyolefin using the supported metallocene catalyst are also disclosed.

Abstract: An automatic wire arranging device includes a controller, at least one driving device electrically connected with the controller, a first wire clamping jig connected with the at least one driving device, a second wire clamping jig disposed to the first wire clamping jig, at least one charge-coupled device camera connected with the controller, and at least one puncher pin connected with the at least one driving device. The first wire clamping jig opens a plurality of first clamping slots. Each of the plurality of the first clamping slots opens a through-hole. The second wire clamping jig opens a plurality of second clamping slots. The at least one puncher pin is capable of penetrating through the through-hole and pushing against a core wire to be away from one of the plurality of the first clamping slots and be blocked in one of the plurality of the second clamping slots.

Abstract: A holding device having a printed circuit board includes a base having a securing recess at a top surface thereof, a securing connector fixed in the securing recess and connected with the printed circuit board, a holding shell rotatably covered to the securing connector, and a flexible antenna of flat plate shape. The antenna has a rectangular radiating body, and a strip-shaped connecting portion extended outwards from a side of the radiating body. A free end of the connecting portion is held by the holding shell and rotated to connect with the securing connector electrically and detachably. An exposed portion of the connecting portion is bent so that the radiating body is attached to the top surface of the base.

Abstract: An electrical connector includes an insulating housing which has a base. Each side surface of the base protrudes outward to form a fixing block and a guiding block. A receiving groove is formed between the fixing block and the guiding block. A plurality of signal terminals are disposed in the insulating housing. A pair of positioning members each has a fixing board fastened in the fixing block. A front end of the fixing board extends frontward and then is arched oppositely to the base to form a flexible board elastically received in the receiving groove and has the apex project out of the receiving groove. When the electrical connector is inserted into the inserting mouth, the guiding block slips into the receiving fillister. The apex of the flexible board slips over the corresponding clipping element and then is restrained by the clipping element.
