As shown in fig. 1 and 2, a SIM card insertion and extraction tester 100 according to an embodiment of the present invention includes:

a work table 110;

a motor 120 located on the table 110;

a screw 130 having a first end connected to the motor 120 and driven to rotate by the motor 120;

a card holder clamp jig 140 for loading a standard card holder 141, installed on the screw 130, and moving along the screw as the screw 130 rotates;

a micropositioner 150 positioned on the table 110 and capable of adjusting position along three dimensions of length, width and height; and

and a PCB 151 positioned on the micropositioner 150 is welded with a standard clamping groove.

In some embodiments, the card-holding jig 140 includes:

a base 142 installed on the screw 130 and having a pressing groove for placing one end of the standard card holder 141 on one side of the top surface thereof;

a horizontal elastic pressing block 143, which is disposed in the base 142 and can be adjusted and elastically abut against one end of the standard card holder 141 from the side;

a vertical elastic pressing block 144 elastically pressing one end of the standard card holder 141 from above;

and a pressing plate 145 detachably mounted on the upper surface of the base 142 and pressing the vertical elastic pressing plate.

In some embodiments, the SIM card insertion and extraction tester 100 further includes a controller 160 mounted at the bottom of the table 110, electrically connected to the motor 120, and configured to control the operation of the motor 120.

The card-holding jig 140 and its base 142 may be mounted on the lead screw 130 directly or through other intermediate components.

As shown in fig. 3 and 4, the right side of the upper portion of the base 142 may be provided with a pressing groove, and the root of a standard card holder may be placed in the pressing groove. A groove may be formed in the middle of the upper portion of the base 142, the horizontal elastic pressing block 143 may be disposed in the groove, the right end of the horizontal elastic pressing block is lower than the root of the standard clamping holder, and the left end of the horizontal elastic pressing block is abutted by a stud penetrating through the base 142. The tightness degree of the horizontal elastic pressing block 143 against the standard clamping support can be adjusted by rotating a knob with a stud extending out of the left side of the base 142. The horizontal resilient pressing piece 143 may be made of a material having suitable elasticity, such as plastic or the like.

The vertical elastic pressing block 144 may be placed on the root of the standard card holder 141 in the pressing groove to elastically press the root of the standard card holder 141. The vertical spring press 144 may be constructed of a suitably resilient material such as plastic or the like.

The pressure plate 145 is removably and adjustably connected to the base 142 by a threaded connection. For example, a plurality of threaded holes may be formed in the base 142, a circular hole with a slightly larger diameter may be formed at a corresponding position of the pressing plate 145, and a stud may pass through the circular hole to be connected to the threaded hole, so as to press the pressing plate 145 on the base 142. By rotating the knob at the top of the stud, the tightness between the pressing plate 145 and the base 142 can be adjusted, and the pressure applied by the vertical elastic pressing block 144 to the root of the standard clamping holder 141 can be adjusted.

The SIM card or SIM/TF composite card to be tested may be placed in a standard card holder 141. The edge of the standard card holder 141 is narrow, so that the standard card holder 141 is clamped by a clamping tool in the test process to be convenient to test, and the standard card holder 141 is easy to wear due to the precision of the manufacturing process, so that the standard card holder is an easily-consumable product and is convenient to replace. According to the utility model discloses a card holds in palm and presss from both sides tool 149 design has adopted modes such as indent, elastic pressing piece to hold in the palm 141 to the standard card and carry out screens, perpendicular roof pressure, horizontal elastic pressing block mode and fix, has both guaranteed firm and has certain elasticity again, has prevented that mechanical plug stress from holding in the palm to the card and causing too big wearing and tearing and damage.

According to the utility model discloses an embodiment, the mode of welding standard draw-in groove has been adopted in the draw-in groove design on standard PCB board. The mode reduces the cost of replacing the card slot for many times, and the test cost is controlled at a lower level. The design of the card support and the card slot clamp jig reduces the replacement steps and the replacement difficulty to the maximum extent.

The PCB 151 is mounted on the micropositioner 150, and the micropositioner can adjust the position of the PCB 151 along the three dimensions of length, width and height, so that the standard card holder 141 and the card slot are accurately aligned, and the abrasion and the test fault caused by dislocation are reduced. In the test process, due to the fact that the card holder and the card slot are small in size and high in precision due to the fact that the card holder and the card slot are subjected to multiple plugging tests, and therefore the test is guaranteed to be conducted smoothly by the aid of the micro-motion table in an alignment assisting mode.

The motor 120 may be a stepping motor, which may be electrically connected to a driver, which may be electrically connected to the controller 160 and receive a control command from the controller to drive the motor to operate. The controller 160 may be a programmable controller, so that the control program may be modularized, which reduces the difficulty of programming the control program, and enables a non-professional person to control and program the device. The running precision and reliability of the testing equipment are ensured through the programmable controller, the driver, the stepping motor and the lead screw.

In some embodiments, since the volume of the object to be tested is small, the precision requirement of the adjustment stage of the testing apparatus is high, and the SIM card plugging and unplugging tester 100 further includes an LED lamp installed on the worktable 110 as the auxiliary lighting for testing.

The SIM card insertion and extraction tester 100 according to the embodiment of the present invention is described above with reference to the drawings, and it should be noted that the above description and drawings are only examples, and are not intended to limit the present invention.
