Description

Technical Field

[0001] The utility model relates to a debugging rack, in particular to a duplexer circuit board debugging rack. Background Art

[0002] A duplexer is an electronic component or assembly used in wireless communication systems that allows transceivers (radio equipment that has both receiving and transmitting functions) to operate simultaneously on the same frequency or on different but very close frequencies. The main function of a duplexer is to isolate the transmit signal from the receive signal to prevent them from interfering with each other.

[0003] During the production process of the duplexer circuit board, some electronic components (such as inductors, etc.) on the circuit board need to be debugged. During the debugging process, the circuit board needs to be placed in a stable state so that the staff can perform debugging operations. The traditional method is for the operator to hold the circuit board with one hand and perform debugging operations with the other hand. During the entire debugging process, the operator needs to hold the circuit board all the time. This operation method is labor-intensive and the operator will be more tired during the long debugging operation.

[0004] If a debugging frame that can effectively fix the duplexer circuit board can be designed, the operator does not need to hold the circuit board with one hand all the time during the debugging process, thereby freeing the operator's hand and reducing the operator's labor intensity during the debugging process.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0025] like Figures 1 to 7As shown, a duplexer circuit board debugging rack includes a base 1, on which a spacing adjustment device is provided, on which two guide columns 6 are provided, and the horizontal spacing between the two guide columns 6 is adjusted by the spacing adjustment device; the guide columns 6 are provided with guide grooves 7, in which a slider adjustment mechanism is provided, on the slider adjustment mechanism there is an insertion rod 10, and at the front end of the insertion rod 10 there is a plug component, and the plug component is used to be inserted into a screw hole 20a on a circuit board 20.

[0026] The utility model can effectively fix the circuit board 20. When fixing the circuit board 20, the plug component at the front end of the insertion rod 10 is inserted into the screw hole 20a on the circuit board 20, so as to fix the circuit board 20. The fixed circuit board 20 is placed in a vertical direction, and this placement state is convenient for operators to debug it. The device can fix the circuit board 20 during the debugging process, so that the operator does not need to hold the debugged circuit board 20 with one hand, freeing up one hand of the operator and reducing the labor intensity during the debugging process. In order to adapt to the position of the screw holes 20a on circuit boards 20 of different specifications, the utility model can adjust the distance between the two guide columns 6 through the distance adjustment device, and the height position of the insertion rod 10 can be adjusted through the slider adjustment mechanism, so as to meet the fixing requirements of circuit boards 20 of different sizes.

[0027] The plug component includes a plug 15 fixedly arranged at the front end of the plug rod 10, and a steel ball hole 17 is arranged on the plug 15. The steel ball hole 17 is arranged along the radial direction of the plug 15, and two steel balls 16 are arranged in the steel ball hole 17, and a spring 19 is arranged between the two steel balls 16; retaining rings 18 for limiting the steel balls 16 are arranged at both ends of the steel ball hole 17. The spring 19 applies elastic pressure to the steel balls 16 on both sides, and one side of the steel balls 16 protrudes from the surface of the plug 15. When the plug 15 is inserted into the screw hole 20a on the circuit board 20, the presence of the steel ball 16 ensures that the circuit board 20 will not easily fall off the debugging frame during the debugging process, thereby improving the stability of fixing the circuit board 20.

[0028] The guide column 6 is provided with a linear through slot 8, which is located on one side of the guide slot 7; the slider adjustment mechanism includes a slider 9 and a locking bolt 11, and the slider 9 is provided with a first threaded hole, and the locking bolt 11 passes through the linear through slot 8 and is connected to the first threaded hole on the slider 9. The plunger is fixedly arranged on the slider 9. When the locking bolt 11 is loosened, the slider 9 can slide in the guide slot 7, thereby realizing the height adjustment of the plunger 10; when the plunger 10 is adjusted to the target height, the locking bolt 11 is tightened to realize the locking of the slider 9.

[0029] In this embodiment, the cross sections of the sliding block 9 and the guide groove 7 are both "T" shaped.

[0030] The spacing adjustment device includes two fixed seats 2 arranged on a base 1, a guide rod 3 and a screw rod 4 are arranged between the two fixed seats 2, the guide rod 3 and the screw rod 4 are parallel to each other, and the two ends of the screw rod 4 are respectively connected to the fixed seats 2 for rotation; a knob 5 is arranged at one end of the screw rod 4; a guide hole and a second threaded hole are arranged on the guide column 6, the guide rod 3 passes through the wire hole, and the screw rod 4 passes through the second threaded hole on the guide column 6; threaded sections are respectively arranged on both sides of the screw rod 4, and the rotation directions of the threaded sections on both sides are opposite; the two guide columns 6 are respectively connected to the threaded sections on both sides of the screw rod 4.

[0031] When the distance between the two guide posts 6 needs to be adjusted, the knob 5 is rotated to drive the screw rod 4 to rotate. When the screw rod 4 rotates, it drives the two guide posts 6 to move closer to or away from each other, thereby adjusting the distance between the two guide posts 6.

[0032] Furthermore, the base 1 is provided with a resistance increasing device for increasing the rotational resistance of the screw 4. The resistance increasing device includes an elastic sheet 13 and a contact block 14. One end of the elastic sheet 13 is fixedly connected to the base 1, and the other end of the elastic sheet 13 is a free end, on which the contact block 14 is arranged; the contact block 14 contacts the outer surface of the screw 4. The elastic sheet 13 forms a certain contact pressure between the contact block 14 and the outer surface of the screw 4, and forms a certain friction force between the two. The existence of the friction force can improve the static stability of the screw 4 in a non-rotating state, so that the screw 4 will not easily rotate during normal use of the device, thereby ensuring the stability of the distance between the two guide columns 6.

[0033] In this embodiment, the elastic sheet 13 is made of spring steel, and the contact block 14 is made of rubber.

[0034] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
