[0042] A universal small module detection device is used for installing modules and printed circuit boards 100, and detecting the modules in cooperation with signal output instruments and test instruments; it comprises a tray 1 for installing the modules, a main body 2 installed on the tray 1 and used for installing the printed circuit board 100, and a pulling device 3 installed on the main body 2 and used for separating the modules from the main body 2; the tray 1 and the main body 2 cooperate with each other to form an installation cavity for module installation.

[0043] Before testing, the module is installed in the installation cavity and the tray 1 is used to effectively support the module. The module is connected to the printed circuit board 100 by plugging and matching with the main body 2. The signal output instrument transmits the signal (low-frequency and / or high-frequency signal) to the printed circuit board 100. Then, the test instrument can be used to test each signal of the printed circuit board 100 to quickly locate the fault signal position. After the test is completed, the module is separated from the main body 2 by the extraction device 3. The utility model sets the module on the outside of the main body 2 structure, and when different modules are connected to the same printed circuit board 100 for testing, the detection of the module is more convenient and quick.

[0044] In some possible implementations, in order to effectively realize the plug-in cooperation between the module and the main body 2 and realize the connection with the printed board 100, and the connection between the signal output instrument and the printed board 100;

[0045] A module socket 21 is provided on the side of the main body 2 close to the installation cavity, and module connectors connected to the module and the printed circuit board 100 are provided in the module socket 21; a signal interface 22 is provided on the side of the main body 2 away from the tray 1; a signal connector connected to the printed circuit board 100 is provided in the signal interface 22;

[0047] Preferably, the signal interface 22 is a plurality of groups, including a low-frequency signal interface 22 and a high-frequency signal interface 22 .

[0048] In some possible implementations, in order to avoid detecting each bit signal of the printed board 100;

[0051] In some possible implementations, in order to enable the tray 1 to support modules of different thicknesses, the module block can be inserted into the module socket 21 and connected to the printed circuit board 100;

[0052] A detachable pad 11 for supporting the module is provided on the tray 1;

[0053] Due to the different sizes of modules, when the main body 2 and the module are inserted, there may be a situation where there is no support at the bottom of the module during insertion. By setting the detachable pad 11, modules of different sizes can be effectively supported to avoid the module being suspended in the air and causing damage at the insertion point.

[0054] In some possible implementations, in order to effectively separate the module from the main body 2 through the extraction device 3;

[0055] The lifting device 3 includes an abutment member 31 installed in the main body 2 and passing through the main body 2 at one end close to the installation cavity, and a driving member installed on the main body 2 and connected to the abutment member 31 and used to control the abutment member 31 to move along the X-axis direction.

[0056] In some possible implementations,

[0057] A cavity for installing the abutment member 31 and the driving member is provided in the main body 2, the printed circuit board 100 is installed in the cavity, the detection window is connected to the cavity, and a slide groove for use with the abutment member 31 is provided on one side of the main body 2 close to the installation cavity; the abutment member 31 is located in the slide groove and slides with the slide groove; the axis of the slide groove is arranged along the X-axis direction;

[0058] The driving member includes a multi-link mechanism 32, one end of which is connected to the side of the abutment member 31 away from the installation cavity and the other end of which is hinged to the main body 2, and a driving handle 33 which is transmission-connected to the multi-link mechanism 32 and located outside the main body 2;

[0059] The driving handle 33 is connected to the multi-link mechanism 32, and the other end of the multi-link mechanism 32 is connected to the abutment 31; the multi-link mechanism 32 is changed by driving the handle 33, so that the abutment 31 moves in the slide groove along the X-axis direction. When it extends out of the main body 2 and abuts against the module, the main body 2 and the module can be separated by continuously applying force.

[0060] In some possible implementations, in order to effectively drive the abutment member 31 through the multi-link mechanism 32 so that it can separate the module from the main body 2;

[0061] The multi-link mechanism 32 includes a transmission shaft 321 connected to the abutment 31 and arranged along the X-axis direction, a hinged rod 322 hinged to the other end of the transmission shaft 321, a connecting rod 323 hinged to the other end of the hinged rod 322, and a support rod 324 hinged to the other end of the connecting rod 323; one end of the driving handle 33 passes through the main body 2 and is transmission-connected to the connecting rod 323; the connection point between the connecting rod 323 and the driving handle 33 is arranged between the hinge point between the connecting rod 323 and the support rod 324 and the hinge point between the connecting rod 323 and the hinged rod 322.

[0062] Furthermore, the transmission shaft 321 and the hinge rod 322 , the hinge rod 322 and the connecting rod 323 , and the connecting rod 323 and the supporting rod 324 are respectively hingedly connected via a group of rotating shafts arranged along the Y-axis.

[0063] In some possible implementations, in order to enable the abutment member 31 to be reset after the module is separated from the main body 2;

[0064] A reset member 34 is also provided on the outer side of the transmission shaft 321; the reset member 34 includes a reset spring 341 sleeved on the outer side of the transmission shaft 321, a fixing member 342 fixedly connected to the main body 2 and sleeved on the outer side of the transmission shaft 321, and a boss 343 fixedly connected to the transmission shaft 321 and located on the side of the reset spring 341 away from the abutment member 31; the boss 343 is provided on the outer side of the transmission shaft 321; when the abutment member 31 is located on the outer side of the main body 2, the reset spring 341 is in a compressed state and its two ends abut against the fixing member 342 and the boss 343 respectively;

[0065] Furthermore, a through hole is provided in the fixing member 342 for the transmission shaft 321 to pass through, and the through hole and the slide slot are coaxially arranged and communicated with each other;

[0066] Specifically, the fixing member 342 is fixedly installed in the main body 2, the transmission shaft 321 is sleeved in the fixing member 342 and the through hole is coaxially arranged; under normal circumstances, the abutment block will be located in the slide groove, and the return spring 341 is in the initial state or pre-compression state; when it is necessary to separate the module from the main body 2, the driving handle 33 controls the connecting rod 323 to rotate clockwise around the Y-axis direction, so that the connecting rod 323 moves upward, thereby driving the hinge rod 322 to move upward around its hinge point with the transmission shaft 321, so that the transmission shaft 321 moves toward the side close to the installation cavity, thereby causing the abutment block to move toward the side close to the installation cavity, and slide out of the slide groove to abut against the module, and the module is separated from the main body 2 by continuously applying a force;

[0067] When the transmission shaft 321 moves toward the side of the installation cavity, the distance between the boss 343 and the fixing member 342 becomes shorter, so that the return spring 341 is in a compressed state. After the module is separated from the main body 2, no force is applied to the driving handle 33, and the return spring 341 will return to the initial state, so that the abutment member 31 moves along the X-axis direction and returns to the slide groove;

[0068] In order to effectively guide the movement direction of the transmission shaft 321; the transmission shaft 321 is also provided with a guide sleeve, and the guide sleeve is located between the return spring 341 and the fixing member 342; at this time, the through hole on the fixing member 342 is a stepped hole, and the large end of the stepped hole will be located on the side close to the guide sleeve, and the inner diameter of the large end is larger than the outer diameter of the guide sleeve;

[0069] The guide sleeve is fixed by the step surface of the fixing member 342 and cannot move to the side close to the module. The transmission shaft 321 continues to move to the side close to the module when the return spring 341 is compressed. The guide sleeve is effectively provided to guide the movement direction of the transmission shaft 321, so that the transmission shaft 321 can only move along the X-axis direction.

[0070] Further, the stepped hole is a two-step stepped hole;

[0071] In some possible implementations, in order to make the modules more evenly stressed during separation;

[0072] The number of the abutment members 31 and the driving members is the same, both are two groups and are symmetrically arranged along the X-axis direction. The driving handle 33 is respectively connected to the two groups of connecting rods 323 in a transmission manner.

[0073] The two groups of abutment members 31 are respectively connected to the two groups of driving members in a one-to-one correspondence. In order to achieve synchronous control of the two groups of driving members by the driving handle 33, the driving handle 33 includes a connecting rod 35 respectively connected to the connecting rod 323;

[0074] The driving handle 33 is a U-shaped structure, including two groups of connecting plates 331 respectively connected to the two groups of connecting rods 323, and a grip rod 332 connected to the other end of the connecting plate 331 to form a U-shaped structure; the connecting plate 331 and the connecting rod 323 are connected by a connecting shaft 333, and the connecting shaft 333 is arranged along the Y-axis direction. The main body 2 is provided with arc-shaped holes for the two groups of connecting shafts 333 to pass through respectively; the center of the arc-shaped hole, the rotation center of the connecting rod 323 and the support rod 324 are on the same straight line along the X-axis;

[0075] When in use, the hand holds the handle 332 to control the connecting shaft 333 to move upward along the arc trajectory of the arc-shaped hole, thereby driving the connecting rod to move upward clockwise around the hinge point between it and the support rod 324, and then driving the hinge rod 322 to move upward counterclockwise around the hinge point between it and the transmission shaft 321, thereby driving the transmission shaft 321 to slide toward the side close to the module, so that the connecting piece slides in the slide groove toward the side close to the module and abuts against the module, and as the force continues, the main body 2 is separated from the module;

[0076] Specifically, the abutment member 31 is disc-shaped, which greatly increases the contact surface between the abutment member 31 and the module, thereby avoiding damage to the module caused by stress concentration; further, a rubber pad is provided on the side of the abutment member 31 close to the module, thereby avoiding damage to the module caused by hard contact with the module.

[0077] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
