DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.
[0021] Please refer to Figures 1 to 2 , a mold for positioning accuracy of PCB gold finger sockets in this embodiment includes a positioning accuracy mold 1. A connecting block 2 is fixed to the rear end of the positioning accuracy mold 1, and an anti-slip pad 3 is fixed to the rear end of the connecting block 2, so that the positioning accuracy mold 1 can be stably placed on the placement surface through the anti-slip pad 3. A pushing component 4 for pushing the PCB gold finger socket out of its interior is provided on the inner wall of the rear wall of the inner cavity of the positioning accuracy mold 1.
[0022] Please refer to Figures 1 to 3 , the pushing component 4 in this embodiment includes two jacking rods 41 slidably connected to the inner wall of the rear wall of the inner cavity of the positioning accuracy mold 1. A sleeve rod 42 is slidably connected inside the two jacking rods 41. Anti-detachment blocks 43 are fixed to both the upper and lower ends of the jacking rods 41. A lifting rod 44 is hingedly connected to the opposite sides of the left and right jacking rods 41. Rubber pads 45 are fixed to the front ends of the two jacking rods 41. When the jacking rods 41 push the PCB gold finger socket to move, the wear phenomenon of the PCB gold finger socket caused by the jacking rods 41 can be reduced. The pushing component 4 further includes a pulling structure provided at the other ends of the two lifting rods 44.
[0023] Among them, two through holes 411 for allowing the two jacking rods 41 to penetrate through its interior are opened at the front end of the connecting block 2. The jacking rods 41 are slidably connected inside the through holes 411, and the jacking rods 41 can move into or out of the connecting block 2 through the two through holes 411.
[0024] Moreover, a communication hole for allowing the two jacking rods 41 to penetrate into its interior is opened at the rear end of the positioning accuracy mold 1. When the jacking rods 41 move out of the connecting block 2, they can move into the positioning accuracy mold 1 through the communication hole, so that the jacking rods 41 can move into the positioning accuracy mold 1, so that the two jacking rods 41 can push out the PCB gold finger socket in the positioning accuracy mold 1.
[0025] In addition, the two jacking rods 41 are in the shape of a cylinder with a hollow interior and a missing rear end. The two sleeve rods 42 are fixed to the rear wall of the inner cavity of the connecting block 2, so that the sleeve rods 42 move into the interior of the jacking rods 41, so that the sleeve rods 42 can limit the moving range of the jacking rods 41.
[0026] Moreover, two vertical chutes are provided on both the upper and lower walls of the inner cavity of the connecting block 2. The anti - detachment blocks 43 are slidably connected to the inside of the vertical chutes, so that the jacking rod 41 can prevent itself from falling out of the connecting block 2 through the two anti - detachment blocks 43.
[0027] Please refer to Figure 3 , in this embodiment, the pulling structure includes a moving plate 46 hinged to the other ends of the two lifting rods 44. Two T - shaped support blocks 47 are fixed on the opposite sides of the two moving plates 46. A gear 48 is engaged on the opposite sides of the two moving plates 46. A rotating rod 49 is fixed inside the gear 48, and a motor 410 is fixed at the top of the rotating rod 49, and the motor 410 is fixed on the front wall of the inner cavity of the connecting block 2.
[0028] Secondly, a plurality of tooth grooves for engaging with the gear 48 are provided on the opposite sides of the two moving plates 46. The upper and lower walls of the gear 48 are engaged with the two groups of tooth grooves, so that the moving plate 46 can be a toothed plate through the multiple tooth roller tooth grooves, so that the moving plate 46 can be engaged with the gear 48.
[0029] At the same time, transverse chutes are provided on both the upper and lower walls of the inner cavity of the connecting block 2. The T - shaped support blocks 47 are slidably connected to the inside of the transverse chutes. The transverse chutes are in a T - shape, so that the two moving plates 46 can move stably in the connecting block 2 through the two T - shaped support blocks 47.
[0030] It should be noted that the electronic components mentioned in the text are all well - known to the public in the prior art, and the control method is controlled by the control terminal, which is well - known to the public in the prior art. And the existing power connection technology and power supply also belong to the common knowledge in this field. Those skilled in the art can simply program and implement it. Therefore, the working principle, circuit connection and control method are not described in detail in the text.
[0031] The working principle of the above - mentioned embodiment is as follows:
[0032] When in use, when the PCB gold finger socket is subjected to precision testing, the staff controls the motor 410 to work through the control terminal, so that the output end of the motor 410 drives the rotating rod 49 to rotate, thereby driving the gear 48 to rotate. When the gear 48 rotates, it meshes with the opposite sides of the two moving plates 46, so that the gear 48 can drive the two moving plates 46 to move away from each other. When the two moving plates 46 move, they can push the jacking rod 41 forward through the two lifting rods 44, so that the sleeve rod 42 gradually moves out of the inside of the jacking rod 41. The jacking rod 41 moves out of the connecting block 2 through the two through - holes 411 and moves into the positioning precision mold 1 through the two communication holes, that is, the two jacking rods 41 can push out the PCB gold finger socket in the positioning precision mold 1, so as to facilitate the staff to take out the PCB gold finger socket after the precision test, and can effectively improve the precision positioning test efficiency of using the PCB gold finger socket.
