BACKGROUND OF THE INVENTION
Field of the Invention
The invention relates to a jig, and more particularly to a jig structure for assembling high frequency connector.
Description of the Related Art
With the vigorous development of the audio-video communication industry, various electronic products continue to pursue better transmission quality and immediacy, and provide diversified applications. These requirements force the signal transmission speed to continue to develop to a high speed. Therefore, the connector as a communication device has become one of the important components of various electronic products.
At present, the production of high frequency connectors still requires manual visual assembly. The assembly method is to use visual methods to magnify the connector through a magnifying glass, and align the central terminal the high frequency connector with the center of the PCB board. The board must be firmly propped against the joint body, and then the fixing screws on both sides are locked. It cannot be continuously produced and assembled.
In such an assembly method, since the size of the central terminal of the high frequency connector is so small that the PCB center cannot ensure the alignment. In addition, the time spent for the manual visual alignment is longer, personnel costs is increased and relative efficiency cannot be improved. It has become the main problem in manufacturing.
BRIEF SUMMARY OF THE INVENTION
In view of the above-mentioned shortcomings, an object of the invention is to provide a jig structure for assembling high frequency connectors, and to quickly locate and assemble the connector components by using a set working tables to reduce the misalignment of manual positioning, increase assembly accuracy, and also improve the yield of the assembled connector.
The invention provides a jig structure for assembling a high frequency connector. The jig structure includes a base on which a rotatable seat is provided. A surface area of the rotatable seat is smaller than that of the base. The rotatable seat is capable of rotating for 360-degree. A fixed table is provided on the rotatable seat. The fixed table further includes a first table. A fixing post is provided at a bottom of each corner end of the first table. A first fixing plate is provided on both sides of the first table. A second fixing plate is symmetrically disposed with the first fixing plate. A first through hole is provided on the first fixing plate, and a groove is provided on the second fixing plate. An adjusting rod extends through the through hole and groove. One end of the adjusting rod is fixed in the groove, the other end of the adjusting rod reaches the other side of the first fixing plate. A handle is provided on the other end to rotate the adjusting rod. A plurality of guide rods are disposed between the second fixing plates and arranged in parallel below the adjusting rod. A plurality of assembly tables are provided on the adjusting rods and the guide rods, and the assembly tables are correspondingly arranged and adjusted by the adjusting rods. A first assembly table and a second assembly table are provided on both sides of the fixed table. The first assembly table has a movement along an X axis and a Y axis, and the second assembly table has a movement along the Y axis, thereby corresponding to the relative position of the assembly table of the fixed table to facilitate rapid placement and assembly of the circuit boards and connectors to be assembled.
A detailed description is given in the following embodiments with reference to the accompanying drawings.

The bottom structure of the adjustment base 44b of the second assembly table 4b, the base plate 41a and the first movable table 42a, are replaced by a plurality of angular posts 48b, and the adjusting base 44b is supported by the angular posts 48b, so that the fixing base 47b of the second assembly table 4b and the first assembly table 4a have identical height.
Referring to FIGS. 4 and 5, which are successive drawings of the schematic diagrams of the assembly operation of the invention. As shown in FIG. 4, the guide rods 4722a correspondingly extend through an assembly base plate 473a. A bracket 4731a extends from one side of the assembly base plate 473a, and a plurality of lock holes 4732a are formed on the assembly base plate 473a. The guide rods 4722a are further provided with a pressure plate 474a, which are stacked on a top surface of the assembly base plate 473a, and a plurality of through holes 4741a are provided on a surface of the pressure plate 474a. The locking holes 4732a should be inserted through by the plurality of screws 475a to fix the relative positions of the pressure plate 474a and the assembly base plate 473a.
As shown in FIG. 5, adjusting the certain the assembly tables 36 of the fixed table 3 to a certain width, and simultaneously adjusting the positions of the first assembly table 4a and the second assembly table 4b to correspond to the assembly tables 36, so that a circuit board 100 is placed and allow the engaging slot 361 and the first assembly stable 4a and the second assembly stable 4b of the assembly table 36 to fix the position of the circuit board 100. Two ends of the circuit board 100 have a plurality of second through holes 101, respectively. The second through holes 101 are respectively sleeved on the guide rods 4722a and 4722b. Then, connectors 200 are respectively placed on the assembly grooves 4721a and 4721b. The connectors 200 are provided with a plurality of fixing holes 201. The positions of the locking holes exactly correspond to the second through holes 101 of the circuit board 100. A plurality of bolts 300 correspondingly extend through the fixing holes 201 and the second through holes 101, and further extend through the through holes 4741a and 4741b to screw into the lock holes 4732a and 4732b, thereby assembling the high frequency connector.
Referring to FIG. 5A, a guiding groove 4723a is formed in the fixed frame 472a, and a guiding groove 4723b is formed in the fixed frame 472b. An elastic member 4724a is disposed in the guiding groove 4723a, and an elastic member 4724b is disposed in the guiding groove 4723b. The guide rod 4722a can move along the guiding groove 4723a, and the guide rod 4722b can move along the guiding groove 4723b. The elastic member 4724a props against the guide rod 4722a, and the elastic member 4724b props against the guide rod 4722b. When the bolts 300 screwed into the fixed hole 201, the bolts 300 push the guide rods 4722a and 4722b to move along the guiding groove 4723a and the guiding groove 4723b respectively. After the bolts 300 moves through the fixed hole 201, the through hole 101, the through hole 4741a to the lock hole 4732a, the guide rod 4722a completely enters the fixed frame 472a. Similarly, After the bolts 300 moves through the fixed hole 201, the through hole 101, the through hole 4741b to the lock hole 4732b, the guide rod 4722b completely enters the fixed frame 472b. The connector 200 is fixed to the circuit board 100 through the assembly base plates 473a, 473b and pressure plates 474a, 474b to constitute a product. When the assembly of the product is completed, the product is removed from the fixed frames 472a and 472b. The elastic members 4724a and 4724b push the guide rods 4722a and 4722b along the guiding grooves 4723a and 4723b to protrude from the fixed frames 472a and 472b respectively.

As shown in FIG. 7, pressing joints 476a and 476b are respectively provided on the top positions of the two fixed frames 472a and 472b. The pressing joint 476a and 476b have positioning post 4761a and 4761b respectively. It is a hollow cylinder. The positioning posts 4761a and 4761b are correspondingly inserted into positioning rods 4762a and 4762b respectively to fix the relative positions of the pressing joints 476a and 476b and the fixed frames 472a and 472b. Positioning bases 4763a and 4763b are connected to the positioning posts 4761a and 4761b respectively. In this embodiment, the positioning bases 4763a, 4763b are triangular, and the positioning base 4763a and 4763b corresponds to the guide rods 4722a, 4722b to be assembled, thereby fixing the connector and preventing the connector from shaking. In addition, in this embodiment, the positioning post 4761a and 4761b are integrally formed with the positioning bases 4763a and 4763b respectively.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
