Abstract: A positioning structure is applied to a male end connector and a female end connector. The female end connector has an inserting slot and two guiding slots. The positioning structure has a case, two guiding pins, two elastic parts, and a positioning member. The two guiding pins are connected to the case. The male end connector is located between the two guiding pins. The elastic parts are connected to the case and to the male end connector. The positioning member has a first positioning hole and two second positioning holes. The first positioning hole is used for the male end connector passing through to enter the inserting slot. The second positioning holes are used for the guiding pin passing through to enter the guiding slot.

Abstract: A connector mechanism is utilized to connect with a portable electronic device which includes a receptacle connector and a guide hole structure. The guide hole structure includes a first area and a second area. The connector mechanism includes a base, a plug connector and a guide pin structure. The plug connector and the guide pin structure are disposed on the base. A length of the guide pin structure is greater than a length of the plug connector. The guide pin structure includes a first portion and a second portion. A width of the first portion is smaller than a width of the second portion. Width difference between the plug connector and the receptacle connector is smaller than width difference between the second portion and the first area and between the first portion and the second area, and is greater than width difference between the second portion and the second area.

Abstract: A shielding can assembly connected to a circuit board for eliminating electromagnetic interference is disclosed, wherein the circuit board has at least one hole. The shielding can assembly has a cover and an assemble element. The cover is situated at a side of the circuit board; the assemble element with at least one assemble portion is situated at another side of the circuit board. The at least one assemble portion passes through the at least one hole to connect with the cover such that the circuit board is situated between the cover and the assemble element.
