Example 2
As shown in fig. 4 to 7, the present embodiment provides a push-pull mechanism 3 capable of moving the positioning adapter plate 2 toward the TR front end module 5, and the push-pull mechanism can realize rapid insertion and extraction of the positioning adapter plate 2 and the TR front end module 5.
Specifically, the push-pull mechanism 3 comprises a force transmission push-pull plate 31, a push-pull rod 35 and a plurality of force transmission columns 33, wherein the first clamping plates 21 are fixed on two sides of the back surface of the positioning adapter plate 2, the second clamping plates 32 are arranged on two sides of the front surface of the force transmission push-pull plate 31, the first clamping plates 21 are in clamping connection with the second clamping plates 32, the plurality of force transmission columns 33 are arranged on the front surface of the force transmission push-pull plate 31, and the push-pull rod 35 is arranged at the center position of the back surface of the force transmission push-pull plate 31.
The plurality of force transmission columns 33 are arranged in an array and mounted on the force transmission push-pull plate 31. The force transmission columns 33 are arranged in a row of 12, three force transmission columns 33 are arranged into a 3x4 array, and the 12 force transmission columns 33 are uniformly abutted on the positioning interface board, so that the positioning adapter board 2 is uniformly stressed when the positioning adapter board 2 and the TR front end assembly 5 are inserted, and the joint can be pulled out relatively in parallel, and the TR assembly and the positioning adapter board 2 are separated without damaging the joint. Meanwhile, the force transmission push-pull plate 31 can well play a role in positioning the lead for the positioning adapter plate 2.
In order to buffer the contact surface between the tension column and the positioning adapter plate 2 when the positioning adapter plate 2 is pushed to the TR assembly, a rubber pad 34 is sleeved at the end part of the force transmission column 33. The rubber pad 34 can be somewhat cushioned, and a very even force pushing of the positioning plate onto the TR front end assembly 5 can be achieved while the force transfer posts 33 are pushing inwards.

It should be understood that, because the number of connectors is relatively large when the positioning adapter plate 2 and the TR front end module 5 are inserted, the connector insertion and extraction force is relatively large, and the force required for insertion and extraction is large, and uneven force can cause the positioning adapter plate 2 to incline, so that the friction force of the connector is increased. In the embodiment 1, the push-pull rod 35 is directly arranged to be connected with the positioning guide rail plate for pushing. Thus, although the problem of inaccurate positioning of the connector is solved, the plugging force is too large, and the stress of the positioning plate is uneven.
In this embodiment, 12 force-transmitting columns 33 are uniformly propped against the interface board, and rubber pads 34 on the force-transmitting columns 33 can buffer to a certain extent, so that the lead screw can push the interface board onto the TR front end assembly 5 with very uniform force while propping inwards.

The second clamping plates 32 on two sides of the force transmission push-and-pull plate 31 are clamped on the first clamping plates 21 of the positioning adapter plate 2, when the positioning adapter plate 2 needs to be moved towards the TR front end assembly 5, the force transmission push-and-pull plate 31 is pushed forward by the rotating push-and-pull rod 35, the force transmission push-and-pull plate 31 can move towards the TR assembly, and in the moving process, the force transmission rods are uniformly distributed, so that stress points are arranged on the upper, middle and lower parts of the positioning adapter plate 2, and the force transmission rods on the force transmission push-and-pull plate 31 can uniformly distribute thrust on the positioning adapter plate 2 to push the positioning adapter plate 2 to be spliced with the TR assembly.
When the test is finished, the positioning adapter plate 2 and the TR front end assembly 5 need to be separated, the push-pull rod 35 is rotated in the opposite direction, so that the force transmission push-pull plate 31 is pulled to move backwards, at the moment, the second clamping plate 32 is clamped with the first clamping plate 21 when moving backwards along with the force transmission push-pull plate 31, so that the positioning adapter plate 2 and the TR assembly are separated from two sides, the adapter plate is uniformly stressed when the joint adapter plate is pulled out, the joint is pulled out relatively parallel, the joint cannot be damaged, and the positioning adapter plate 2 is conveniently detached for replacement.
