The connecting part is sleeved and connected to the outside of the threaded rod 2, i.e., the base 1 and the threaded rod 2 are connected in sliding sleeve connection. The two support parts are symmetrically connected to the connecting part, and are located on the two sides of the threaded rod 2.

[0047] ​Two centering rods 3 are symmetrically connected to the base 1, the upper ends of the centering rods 3 are hingedly connected to the connecting part of the base 1, the two centering rods 3 are separately arranged on the two sides of the threaded rod 2, and the two centering rods 3 are staggered with the two supporting parts. The upper end of the centering rod 3 is provided with a gear, the connecting part is provided with a hinged seat, and the center of the gear is hingedly connected to the hinged seat. The edge of the gear is in contact with the thread on the outer surface of the threaded rod 2, and the threaded rod 2 is used to drive the rotation of the two centering rods 3. When the threaded rod 2 rotates, the gear rotates with it, that is, the centering rod 3 rotates, and the angle between the centering rod 3 and the threaded rod 2 changes. The lower end of the centering rod 3 is provided with a fitting block, the inner side of the fitting block is a circular arc surface, and the circular arc surface is matched with the outer cylindrical surface 8 of the electronic component connector mounting area. When the threaded rod 2 rotates, the two centering rods 3 on the two sides rotate towards each other until the fitting block is tightly in contact with the outer cylindrical surface 8 of the electronic component connector mounting area, so as to ensure that the axis of the centering rod 3 is consistent with the axis direction of the connector mounting hole 9, and ensure that the axis of the tightening rod 4 is coincided with the axis of the connector mounting hole 9.

[0048] The threaded rod 2 is a hollow structure, the center of the threaded rod 2 is provided with a first through hole, the first through hole is provided with a tightening rod 4, and the tightening rod 4 penetrates through the first through hole of the threaded rod 2. The bearing 5 is arranged between the tightening rod 4 and the threaded rod 2, and the bearing 5 is arranged in the first through hole. The bearing 5 is used to ensure the reliable assembly between the centering rod 3 and the threaded rod 2.

[0049] The upper end of the tightening rod 4 is provided with a tightening part 401, the size of the tightening part 401 is larger than the size of the first through hole, the shape of the tightening part 401 is matched with the clamping opening of the torque wrench, and the torque wrench can apply force to the tightening part 401 to make the tightening rod 4 rotate. The tightening rod 4 is also a hollow structure, the center of the tightening rod 4 is provided with a second through hole, the upper end of the tightening rod 4 is used to be connected with a vacuum suction air pipe, and the lower end of the tightening rod 4 is provided with a tapered groove.

[0050] When the electronic component 7 needs to be assembled with the threaded SMP connector 6, the tightening rod 4 with the vacuum suction air pipe connected externally sucks the threaded SMP connector 6 at the lower end of the tightening rod 4, after the threaded SMP connector 6 is sucked, the substrate 1 is placed in contact with the corresponding plane of the electronic component 7, the threaded rod 2 is rotated to drive the two centering rods 3 to rotate towards each other until the lower end of the centering rod 3 is in close contact with the outer cylindrical surface 8 of the connector mounting area of the electronic component, so that the axis of the tool coincides with the axis of the connector mounting hole 9.

[0051] The tightening rod 4 is moved downward to preliminarily assemble the connector 6 into the mounting hole, and then the tightening rod 4 is rotated in the tightening direction of the connector 6 using a torque wrench, so that the connector 6 can be accurately assembled into the electronic component 7 according to the required torque.

[0052] By using the above tool, the threaded SMP connector 6 is reliably sucked at the lower part of the tightening rod 4 with the vacuum suction air pipe connected externally, the centering rod 3 is rotated under the drive of the threaded rod 2 and is in close contact with the outer cylindrical surface 8 of the connector mounting area of the electronic component, so that the axis of the tightening rod 4 coincides with the axis of the connector mounting hole 9, and then the torque wrench is used to complete the torque tightening of the connector 6, and the reliable assembly of the threaded SMP connector 6 in the electronic component 7 is completed. Compared with the current manual assembly of the threaded SMP connector, the use of the tool changes the manual process without control and easy damage into a process relying on the tool, which can reduce the damage of the connector in the manual assembly process and ensure the accurate control of the compression amount of the floating hard needle of the connector.

[0053] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes.
