Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0022] Example: This application proposes a welding fixture for a radio frequency antenna female connector, referring to... Figure 1-4 The system includes a fixed base 1, a female antenna positioning module 2, and a main control board positioning module. The female antenna positioning module 2 is fixedly installed at one end of the upper surface of the fixed base 1 and is used to place and position the RF antenna female antenna. The main control board positioning module is a combined structure and is laid at other positions on the upper surface of the fixed base 1. The main control board positioning module is used to position the main control board, so that the main control board and the RF antenna female antenna can be accurately connected and soldered. The main control board positioning module includes two main control board positioning modules 3 set at both ends and several main control board lower positioning modules 4 set between the two main control board positioning modules 3.

[0023] The fixed base 1 is set as a rectangular metal flat plate, which can maintain the stability of the entire fixture.

[0024] The female seat positioning module 2 is fixedly mounted on the upper surface of one end of the fixed base 1 along its length. The female seat positioning module 2 includes a base connecting strip 21 and a female seat positioning seat 22.

[0025] The base connecting strip 21 has a long strip structure and is integrally formed with the fixed base 1. The length direction of the base connecting strip 21 is perpendicular to the length direction of the fixed base 1, and one side of the base connecting strip 21 is coplanar with one end face of the fixed base 1.

[0026] The female antenna positioning base 22 is designed as a rectangular block structure and is bolted to the upper surface of the base connecting strip 21, allowing the female antenna positioning base 22 to be replaced to meet the installation requirements of different models of RF antenna female antennas. The female antenna positioning base 22 has a female antenna placement slot 23 that is compatible with the model of the RF antenna female antenna. The female antenna placement slot 23 is open on the upper side and at both ends, allowing the RF antenna female antenna to be embedded into the female antenna placement slot 23 for positioning.

[0027] To secure the RF antenna mount more firmly, this application provides elastic pads on both side walls of the mount placement slot 23. Utilizing the deformable nature of the elastic pads, the RF antenna mount is effectively protected and its placement is made more secure.

[0028] The base connecting strip 21 has several connecting holes 24 evenly spaced along its length. Each connecting hole 24 is square, extending through both ends to the left and right sides of the base connecting strip 21. The axis of the connecting holes 24 is perpendicular to the length of the base connecting strip 21. A rubber pad is provided on the inner wall of each connecting hole 24. The positioning module 3 on the main control board and the lower positioning module 4 on the main control board are both inserted into the connecting holes 24. The rubber pad increases the stability of the connection between the positioning modules 3 and 4 on the main control board and the base connecting strip 21, preventing them from easily slipping out.

[0029] This application includes two sets of positioning modules 3 on the main control board and two or more sets of positioning modules 4 on the lower part of the main control board. The positioning modules 3 on the main control board and the positioning modules 4 on the lower part of the main control board are arranged in parallel, with their length direction perpendicular to the length direction of the female positioning module. The two sets of positioning modules 3 on the main control board are located on the outermost side, and the multiple positioning modules 4 on the lower part of the main control board are located between the two sets of positioning modules 3 on the main control board.

[0030] Furthermore, the positioning module 3 on the main control board includes a first connecting strip 31, a first insert 32, and two sets of main control board clamping assemblies. The first connecting strip 31 is a long strip of metal, and the first insert 32 is a rectangular block with a cross-sectional dimension smaller than that of the first connecting strip 31. The first insert 32 is fixedly connected to one end of the connecting base connecting strip 21 of the first connecting strip 31. The first connecting strip 31 is inserted into the connecting socket 24 through the first insert 32. After the first connecting strip 31 is vertically connected to the base connecting strip 21, one end of the first connecting strip 31 abuts against the base connecting strip 21, and the other end is flush with the end face of the fixed base 1. The first connecting strip 31 is also flush with the upper surface of the base connecting strip 21.

[0031] A clearance groove 33 is provided on the upper side of the first connecting strip 31. The clearance groove 33 extends to both sides of the first connecting strip 31 and makes way for electronic components on the main control board.

[0032] The main control board clamping assembly includes a fixed post 34, a guide post 35, a U-shaped clamping claw 36, and a connecting spring 37. The fixed post 34 is vertically fixedly connected to the upper surface of the first connecting strip 31 near the end. In this embodiment, the fixed post 34 is set as a cylinder. The guide post 35 is coaxially fixedly connected to the upper end of the fixed post 34. The diameter of the guide post 35 is smaller than the diameter of the fixed post. The U-shaped pressure claw 36 is set as a U-shaped frame structure with the opening direction facing downward. One side of its rod is slidably sleeved on the guide post 35, and the other side of its rod is located above the positioning module 4 under the main control board, used to press down on the main control board. The U-shaped pressure claw 36 can slide up and down on the guide post 35. The connecting spring 37 is sleeved on the guide post 35. The lower end of the connecting spring 37 is fixedly connected to the upper end face of the fixed post 34, and the lower end is fixedly connected to the lower end face of the side rod of the U-shaped pressure claw 36 sleeved on the guide post 35. The connecting spring 37 pulls down the U-shaped pressure claw 36 to prevent the U-shaped pressure claw 36 from detaching from the guide post 35, and at the same time pulls down the U-shaped pressure claw 36 to press down on the main control board.

[0033] The main control board lower positioning module 4 includes a second connecting strip 41, a second insert strip 42, and a main control board support assembly. The second connecting strip 41 has the same shape and size as the first connecting strip 31, and the second insert strip 42 has the same shape and size as the first insert strip 32. The second insert strip 42 is fixedly connected to one end of the connecting base connecting strip 21 of the second connecting strip 41. The second connecting strip 41 is inserted into the connecting socket 24 through the second insert strip 42. After the second connecting strip 41 is vertically connected to the base connecting strip 21, one end of the second connecting strip 41 abuts against the base connecting strip 21, and the other end is flush with the end face of the fixed base 1. The second connecting strip 41 is also flush with the upper surface of the base connecting strip 21.

[0034] The second connecting strip 41 has a clearance groove 33 on its upper side, which extends to both sides of the second connecting strip 41. The clearance groove 33 makes way for the electronic components on the main control board.

[0035] In this embodiment, the main control board support assembly is installed on two of the second connecting strips 41. Two sets of main control board support assemblies are installed on each second connecting strip 41. The main control board support assembly includes a lower adjusting column 43 and an upper adjusting column 44. The lower adjusting column 43 is threaded to the upper surface of the second connecting strip 41, and a threaded hole is opened axially at the upper end of the lower adjusting column 43. The upper adjusting column 44 is threaded into the threaded hole at the upper end of the lower adjusting column 43. A polygonal nut is provided at the top of the upper adjusting column 44, which abuts against the main control board from the bottom.

[0036] When using the fixture of this application, the order of the lower positioning module 4 of the main control board is adjusted according to the position of the electronic components on the main control board, so that the main control board support component avoids the position of the electronic components. The position of the electronic components corresponds to the clearance slot 33. Then the upper adjustment column 44 is leveled, and the main control board is placed on it to connect with the RF antenna socket. Then the main control board is pressed by the main control board pressing component, and finally the main control board and the RF antenna socket are soldered.
