Description

Technical Field

[0001] The utility model relates to the technical field of SMA adapter processing, and more specifically, to a safety clamp for a chip SMA adapter. Background Art

[0002] SMA series products are a widely used small threaded coaxial connector, which has the characteristics of wide frequency band, excellent performance, high reliability and long life. It is suitable for connecting RF cables or microstrip lines on chipsets of microwave equipment and digital communication systems.

[0003] At present, during the production process of SMA adapters, it is necessary to punch a hole in the SMA socket so that the antenna feeder core can be inserted into the SMA socket. However, the existing SMA sockets are of right-angle type (see the attached manual). Figure 1 ), therefore, holes are punched on the upper side and the side of the SMA seat. However, after most of the existing SMA adapter clamps clamp the SMA seat, in order to ensure its safety during processing, the existing SMA seat cannot be rotated after being clamped. Therefore, after drilling a hole on one side, the SMA seat needs to be removed from the clamp, and then the other side is clamped again, so that the other side of the SMA seat can be drilled. This increases the operating steps when drilling or grinding the two sides of the SMA adapter, and reduces the efficiency and speed of the SMA adapter processing. In view of the above problems, the inventor has designed a safety clamp for a chip SMA adapter. Utility Model Content

[0021] See also Figure 1-4 , the utility model provides the following technical solutions:

[0022] Specifically, it refers to a safety clamp for a chip SMA adapter, including a placement base 1 and an SMA adapter 4 placed on the placement base 1, two movable bases 2 are provided on opposite sides of the placement base 1, two extrusion plates 3 are provided on the two movable bases 2, the two extrusion plates 3 are provided on both sides of the SMA adapter 4, and clamp the SMA adapter 4, a clamping component is provided in the placement base 1, a rising component is provided on the movable base 2, and a rotating component is provided on the extrusion plate 3, the two extrusion plates 3 are controlled to clamp the SMA adapter 4 through the clamping component, and the rotating component can control the rotation of the SMA adapter 4.

[0023] Specifically, the clamping assembly includes a threaded rod 101, which is arranged in the placement base 1. The two ends of the threaded rod 101 are respectively rotatably connected to the inner wall of the placement base 1. A threaded sleeve 102 is threadedly sleeved on the outer surface of the threaded rod 101. An adjusting slide rod 103 is fixedly connected to the surface of the movable base 2 on one side close to the placement base 1. The other end of the adjusting slide rod 103 slides into the placement base 1. A rotating push plate 104 is hinged between the outer surface of the threaded sleeve 102 and the adjusting slide rod 103.

[0024] Specifically, one end of the threaded rod 101 rotates and passes through the outer surface of the placement base 1. The end of the threaded rod 101 located outside the placement base 1 can be provided with a handle or a servo motor, which can be set according to actual processing requirements and is not restricted too much here.

[0025] When in use, by driving the threaded rod 101 to rotate, since both sides of the threaded sleeve 102 are restricted by the rotating push plate 104, the threaded sleeve 102 will move under the drive of the thread of the threaded rod 101. When the threaded sleeve 102 moves toward the side close to the center of the placement base 1, the threaded sleeve 102 will form a thrust on the rotating push plate 104, so that the adjusting slide bar 103 synchronously pushes the movable base 2 to move toward the side away from the placement base 1. Therefore, the SMA adapter 4 can be placed on the placement base 1. When the threaded sleeve 102 moves toward the side away from the center of the placement base 1, the threaded sleeve 102 will form a pulling force on the rotating push plate 104, so that the adjusting slide bar 103 synchronously pulls the movable base 2 to move toward the side close to the placement base 1. In this way, the two extrusion plates 3 can squeeze and fix the SMA adapter 4, thereby avoiding the problem of loosening of the SMA adapter 4 during drilling as much as possible, and further ensuring the safety of the SMA adapter 4 during processing.

[0026] Specifically, the rotating assembly includes an extrusion disk 301, which is arranged on the side of the extrusion plate 3 close to the placement base 1. When the extrusion plate 3 moves toward the side of the SMA adapter 4, the extrusion disk 301 contacts the outer surface of the SMA adapter 4, so the SMA adapter 4 is clamped and fixed by the extrusion disk 301 on the extrusion plate 3.

[0027] Specifically, the interior of the extrusion plate 3 is hollow, and a movable shaft 302 is fixedly connected to the surface of one side of the extrusion disk 301 close to the extrusion plate 3. The other end of the movable shaft 302 rotates through the extrusion plate 3 and is rotatably connected to the inner wall of the extrusion plate 3. A worm gear 303 is fixedly sleeved on the outer surface of the movable shaft 302 located inside the extrusion plate 3. A worm 304 is meshingly connected to the bottom of the worm gear 303, and the two ends of the worm 304 are rotatably connected to the inner walls of the two sides of the extrusion plate 3 respectively.

[0028] Specifically, one end of the worm 304 rotates and passes through the outer surface of the extrusion plate 3. The end of the worm 304 outside the extrusion plate 3 can also be provided with a handle or a servo motor, which can be set according to actual processing requirements and is not restricted too much.

[0029] When it is necessary to drill a hole on the other side of the SMA adapter 4, by driving the worm 304 to rotate, the worm 304 meshes and drives the worm wheel 303 to rotate ninety degrees, so that the movable shaft 302 synchronously drives the extrusion plate 301 to rotate ninety degrees, so that the extrusion plate 301 synchronously drives the SMA adapter 4 to rotate ninety degrees, thereby achieving the purpose of changing the surface of the SMA adapter 4. This method avoids the need to remove the SMA adapter 4 from the fixture and manually change the surface when drilling or grinding the two sides of the SMA adapter 4, reduces the operating steps when drilling or grinding the two sides of the SMA adapter 4, and further improves the efficiency and speed of processing the SMA adapter 4.

[0030] Specifically, the lifting component includes a lifting rod 201, which is fixedly installed on the movable base 2. The upper end of the lifting rod 201 slides through the extrusion plate 3. A limiting ring 202 is fixedly sleeved on the outer surface of one end of the lifting rod 201 located in the extrusion plate 3. A spring 203 is fixedly connected between the limiting ring 202 and the bottom wall of the extrusion plate 3. The spring 203 is movably sleeved on the outer surface of the lifting rod 201. When the spring 203 is not squeezed, it will generate a thrust on the limiting ring 202 and the extrusion plate 3, so that the initial position of the extrusion plate 3 is in contact with the top surface of the movable base 2.

[0031] Specifically, a driving disk 204 is fixedly sleeved on the outer surface of the movable shaft 302, and four arc-shaped extrusion blocks 205 arranged in a circumferential array are fixedly connected to the outer surface of the driving disk 204. The shape of the arc-shaped extrusion blocks 205 is an isosceles triangle. The upper end of the lifting rod 201 contacts and slides with the outer surfaces of the driving disk 204 and the arc-shaped extrusion blocks 205. When the movable shaft 302 rotates, the driving disk 204 rotates synchronously. When the lifting rod 201 slides to the outer surface of the arc-shaped extrusion blocks 205, the arc-shaped extrusion blocks 205 will squeeze the lifting rod 201, so that the extrusion plate 3 moves upward. Since the shape of the arc-shaped extrusion blocks 205 is an isosceles triangle, after the driving disk 204 rotates more than forty-five degrees, the inclined surface of the arc-shaped extrusion blocks 205 no longer squeezes the lifting rod 201, so that the extrusion plate 3 is moved to the initial position under the push of the spring 203. In this way, the extrusion plate 3 can be synchronously driven to rise during the rotation of the SMA adapter 4, and the problem of the SMA adapter 4 being stuck with the placement base 1 when rotating can be avoided as much as possible.

[0032] The working principle of the chip SMA adapter safety clamp provided by the utility model is as follows: by driving the worm 304 to rotate, the worm 304 meshes and drives the worm wheel 303 to rotate ninety degrees, so that the movable shaft 302 synchronously drives the extrusion disk 301 to rotate ninety degrees, so that the extrusion disk 301 synchronously drives the SMA adapter 4 to rotate ninety degrees, thereby achieving the purpose of changing the surface of the SMA adapter 4;

[0033] When the movable shaft 302 rotates, the driving disk 204 rotates synchronously, and the lifting rod 201 slides to the outer surface of the arc-shaped extrusion block 205. The arc-shaped extrusion block 205 will squeeze the lifting rod 201, causing the extrusion plate 3 to move upward. Since the shape of the arc-shaped extrusion block 205 is an isosceles triangle, after the driving disk 204 rotates more than forty-five degrees, the inclined surface of the arc-shaped extrusion block 205 no longer squeezes the lifting rod 201, so that the extrusion plate 3 moves downward under the push of the spring 203 until it contacts the surface of the movable base 2.
