Abstract

The invention provides an instrument for intelligently detecting a Nano SIM card dynamic signal, and the instrument comprises a circuit board main body and an external Nano card seat, an external Micro SIM card seat, a plurality of LED signal indicating lights and a plurality of test pin contacts which are arranged on the circuit board main body; one end of the circuit board main body extends outwards and comprises a connecting plug which is used for inserting to a socket of to-be-detected equipment; and a pad which simulates a Nano SIM card is welded with the back of the plug; and the pack on the back of the plug, the external Nano card seat, the external Micro SIM card seat, the plurality of LED signal indicating lights and the plurality of test pin contacts have VCC, CLK, RST, IO and VPP contacts. According to the invention, the design adopts a low voltage red LED light to perform signal indication, the instrument can dynamically and precisely display if a state of each signal exists in real time, the instrument is convenient to help engineering technicians and general maintenance personnel quickly locate which signal is not conducted, the reliability is high, and engineering research personnel can more conveniently and quickly analyze and locate a problem.

Description

[0001] [technical field] [0002] The invention relates to the technical field of SIM detection equipment, in particular to an instrument and equipment for intelligently detecting the dynamic signal of a Nano SIM card with fast detection speed, high precision and convenient use. [0003] [Background technique] [0004] Tablet PCs used in daily life generally have 2G / 3G call functions and 4G-LTE data transmission functions. In tablet PCs with these functions, it is essential to keep the SIM card slot. The SIM card is the user identification card connected to the operator. Only when the SIM card is correctly pressed into the SIM card slot of the tablet computer, the tablet computer can complete GMS communication and wireless data transmission. Because the SIM card slot is often plugged and pulled out, the SIM card slot is prone to defects. For example, problems such as broken shrapnel inside the SIM card slot, deformation, and false welding of the card slot will cause the SIM car...
