A Subscriber Identity Module (SIM) card connecting device for a portable electronic device which is adapted to further reduce a thickness of the portable electronic device by limiting the height of the SIM card connecting device. The device includes: a printed circuit board (PCB); one or more patterned contacts provided on the PCB and being coupled with one or more contacts formed on the SIM card; and a housing mounted on the PCB for allowing the SIM card to be inserted into / extracted from the housing. The housing presses the inserted SIM card so that the contacts of the SIM card and the patterned contacts come into substantial pressurized contact and / or pressurized contact with each other, depending on a shape of the patterns. According to the present invention, the SIM card mounting space can be reduced, and the portable electronic device can have a further reduction in thickness.

The invention relates to an electronic component moving test device and an electronic component moving test method applying the electronic component moving test device. The electronic component moving test device comprises a bearing jig and a detection instrument, and a conductive body is fixedly arranged on the bearing jig. The electronic component moving test method comprises the following steps: firstly, an electronic component is inserted to a component connecting end of the conductive body; secondly, the electronic component is electrically connected with a component contact part of the detection instrument, and the conductive body is electrically connected with an instrument contact part of the detection instrument to form a loop for testing; thirdly, the electronic component and the conductive body are respectively disconnected from the component contact part and the instrument contact part of the detection instrument after a test is completed; fourthly, the bearing jig inserted with the electronic component is moved to a workstation of the next detection instrument; fifthly, the electronic component is electrically connected with the component contact part of the next detection instrument, and the conductive body is electrically connected with the instrument contact part of the detection instrument to form the loop for testing; and sixthly, step two to step five are repeated until all tests are completed.

The invention discloses a novel USB flash disk capable of being quickly pulled away. The USB flash disk comprises a main body and an outer cover. The main body is composed of a housing, an indicating lamp, a locking press button, a core assembly and a master control circuit; a power cut-off circuit is additionally installed in the main body and is used for cutting off electrical connection between the USB flash disk and a computer, and the on / off state of the power cut-off circuit is controlled by a power cut-off button arranged on the main body. The USB flash disk capable of being quickly pulled away revealed in the invention is additionally provided with the power cut-off circuit which can quickly and accurately cut off the electrical connection between the USB flash disk and the computer, so the speed of pulling the USB flash disk away from a computer case is increased; meanwhile, the power cut-off circuit is controlled by the externally arranged power cut-off button, and the power cut-off circuit is convenient to operate and use, is safe and reliable and greatly improves operating efficiency of computers by people.
