Technical Field

[0001] The utility model belongs to the technical field of antenna manufacturing, and in particular relates to a PCB antenna feeder connection auxiliary device. Background Art

[0002] PCB antenna is a trace printed on PCB. It can be drawn as a straight trace, an inverted F-shaped trace, a serpentine or circular trace, etc. A quarter wavelength can basically form an antenna to radiate or receive electrical signals. Feeder refers to the transmission line that connects the antenna to the transmitter and receiver to transmit radio frequency energy. In the process of making PCB antenna, the feeder needs to be welded to the antenna. The existing method generally uses manual fixing of the PCB board, and then holding the feeder with one hand and holding a soldering gun with the other hand to weld the feeder to the PCB board. Manually holding the feeder requires constant control of the feeder position, which is easy to fatigue and has low work efficiency when working for a long time. Utility Model Content

[0024] The present invention will be further explained below in conjunction with specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, a PCB antenna feeder connection auxiliary device includes a base 1, a clamping member 2, a universal bracket 3 and a feeder clamp 4. The base 1 is a rectangular base. Four clamping members 2 are provided and are arranged above the base 1. The upper surface of the base 1 is provided with a first slide groove 11 and a second slide groove 12. The second slide groove 12 is arranged in the middle position and extends along the length direction of the base 1. There are two second slide grooves 12. The two second slide grooves 12 are symmetrically arranged on both sides of the first slide groove 11. The first slide groove 11 and the second slide groove 12 are both T-shaped grooves. The clamping member 2 is a bar block and its length extension direction is perpendicular to the length extension direction of the base 1. Two first sliders 24 corresponding to the first slide groove 11 are provided at the bottom of the clamping member 2. The first slider 24 is a T-shaped block. The first slider 24 slides left and right on the first slide groove 11 to adjust the left and right position of the clamping member 2. The second slide groove 12 is slidably connected with a first T-shaped bolt 13. The clamping member 2 is provided with a through hole corresponding to the first T-shaped bolt 13. The first T-shaped bolt 13 penetrates the clamping member 2 upward. The first T-shaped bolt 13 is connected with a first positioning nut 14. In this embodiment, the first positioning nut 14 adopts a butterfly nut. The position of the clamping member 2 can be fixed by tightening the first positioning nut 14. By loosening the first positioning nut 14, the clamping member 2 can slide, so that the distance between several clamping members 2 can be adjusted to adapt to PCB boards 91 of different widths.

[0026] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the universal bracket 3 is connected to the clamping member 2. The universal bracket 3 is a universal metal shaped hose. The universal metal shaped hose can be bent at multiple angles and fixed in the bent position. The universal metal shaped hose is a metal tube formed by winding and wrapping stainless steel metal wire. The inside is hollow and there are spiral patterns on the outside. It can be bent into various shapes at multiple angles within a certain range in three-dimensional space and can maintain the stability of its shape. After bending, the hose has a certain supporting force. In this embodiment, the universal metal shaped hose adopts the existing metal shaped hose, the outside of which can be coated with rubber for corrosion and rust prevention, and it can be bent and shaped without rebounding. One end of the universal bracket 3 is connected to a stud 31, and the clamping member 2 is provided with a threaded hole 25, which corresponds to the stud 31. Two threaded holes 25 are symmetrically arranged on the clamping member 2 (the number is set according to the use requirements). According to the shape and position of the PCB board 91, the universal bracket 3 is selected to be connected to one of the threaded holes 25. The other end of the universal bracket 3 is connected to the feeder clamp 4. The feeder clamp 4 adopts the existing A-shaped clamp. The feeder clamp 4 is used to clamp the feeder 92. An anti-skid pad is provided on the clamping mouth of the feeder clamp 4. The anti-skid pad is made of rubber material. The anti-skid pad can protect the feeder 92 when the feeder clamp 4 is clamped to prevent it from being damaged.

[0027] like Figure 1 and Figure 4As shown, two grooves 21 are symmetrically arranged on both sides of the clamping member 2, and the grooves 21 are rectangular grooves. A plurality of elastic members 22 are arranged on the inner wall of the grooves 21, and the elastic members 22 are springs. The outer ends of the elastic members 22 are connected to the clamping blocks 23. When the clamping blocks 23 are pushed from the outside to the inside, the clamping blocks 23 overcome the elastic force of the elastic members 22 and move into the grooves 21. The clamping blocks 23 correspond to the positions of the clamping blocks 23 of the adjacent clamping members 2, and the clamping blocks 23 at the corresponding positions of the two adjacent clamping members 2 are used to clamp the PCB board 91. When in use, the PCB board 91 is placed between the two adjacent clamping members 2, and the corresponding clamping blocks 23 are pushed on both sides of the PCB board 91, so that the PCB board 91 is fixed between the two adjacent clamping members 2.

[0028] like Figure 2 and Figure 4 As shown, the clamp block 23 is provided with a supporting bottom 231, which extends outward for a certain distance, and can support the PCB board 91 from below when placing the PCB board 91 to prevent the bottom of the PCB board 91 from contacting the base 1. A buffer pad 232 is connected to the outer surface of the clamp block 23, and the buffer pad 232 is made of rubber material to protect the PCB board 91.

[0029] When the auxiliary device of this embodiment is in use, the spacing between the clamping members 2 is adjusted so that the spacing corresponds to the width of the PCB board 91 to be welded, the PCB board 91 is placed between the clamping members 2, the PCB board 91 is clamped and fixed by the clamping block 23, the universal bracket 3 is bent and adjusted to a suitable position, the feeder clamp 4 is used to clamp the feeder 92, the end of the feeder 92 to be welded is close to the point on the PCB board 91 to be welded, and then the welding operation is performed.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
