Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing, specifically to a radio frequency cable assembly bushing cutting device. Background Technology

[0002] Increasingly, soldering is used to connect the outer conductors of RF cable assemblies and RF connectors, resulting in superior high-frequency performance. However, solder overflow is unavoidable during the soldering process between the cable's outer conductor (shielding layer) and the connector's outer conductor (sheath). Figure 8 As shown, excess solder must be removed and the cable shielding layer and bushing end face must be cut neatly before proceeding to the next step. This requires a tool to assist in removing excess solder and the cable shielding layer.

[0003] Currently, the following methods are used for cutting: The first method involves holding a blade close to the end face of the bushing to cut away excess solder. This method has the problems of difficulty in cutting the end face smoothly and low cutting efficiency, and it also has a significant impact on the VSWR and insertion loss of the cable assembly. The second method is to use a bench lathe chuck to clamp the welded bushing when the cable assembly is very short, start the lathe, and use a cutting tool to cut away excess solder and the cable shielding layer close to the end face of the bushing. This method is not suitable for processing longer cable assemblies because the cable needs to rotate. The third method often uses a cyclone lathe structure. The welded bushing is horizontally clamped at the fixed end of the cyclone lathe, and the cutting tool of the cyclone lathe is used to cut away the cable shielding layer and solder axially. This method is prone to cable deformation and scrapping during the machining process because the cable does not have sufficient strength, and the electroplated layer on the end face of the bushing is easily cut off.

The structure of the radio frequency cable assembly is as follows. Figure 8 As shown.

[0043] The cable clamping base 3 is provided with a cable clamping assembly 6, which is used to clamp the radio frequency cable assembly.

[0044] A cutting component 7 is rotatably mounted on the fixed base 4 at the position corresponding to the cable clamping assembly 6. The cutting component 7 includes at least a blade holder 702 and a blade 706. By rotating the cutting component 7, the blade holder 702 and the blade 706 are driven to completely cut off the excess solder and cable shielding layer on the RF cable assembly.

[0045] Specifically, the cutting device provided by this utility model clamps and fixes the RF cable assembly using the cable clamping assembly 6, and completely cuts off excess solder and cable shielding layer using the rotating cutting assembly 7, ensuring the flatness of the bushing end face and the cable in this batch. The cable clamping seat 3 is slidably disposed on the base 1 to control the length of the RF cable assembly's inlet, thereby gradually cutting off excess solder and cable shielding layer on the RF cable assembly. The blade 706 is fixed to the cutting assembly 7 by the blade bracket 702. The cutting assembly 7 can rotate on the fixing base 4. By rotating the cutting assembly 7, the blade 706 can perform rotary cutting of the RF cable assembly.

[0046] Optionally, the cutting assembly 7 includes a rotating frame 701 and a bearing, with the bearing embedded in the fixed base 4, and the rotating frame 701 being rotatably mounted on the fixed base 4 via the bearing.

[0047] One end of the blade holder 702 is fixed to the rotating frame 701, and the other end is fixed with the blade 706.

[0048] Specifically, such as Figure 2 , Figure 3 As shown, a bearing is first embedded in the fixed base 4, and a rotating frame 701 is installed inside the bearing, thus realizing the rotational setting between the rotating frame 701 and the fixed base 4. The right end of the blade holder 702 is fixed to the rotating frame 701, and the blade 706 is set at the left end. By rotating the rotating frame 701 on the right side, the blade 706 can be rotated.

[0049] Optionally, the front and back of the rotating frame 701 protrude from the fixed base 4. The rotating frame 701 has a ring-shaped structure, and the center of the rotating frame 701 is an inner cavity 708, which is designed to facilitate the blade holder 702 to pass through it.

[0050] like Figure 5 As shown, the blade holder 702 has a T-shaped structure. The blade holder 702 includes a first part 7021 and a second part 7022.

The right end of the first part 7021 is connected to the middle of the second part 7022. The first end of the second part 7022 is fixed to the outer wall of the rotating frame 701, and a return spring 707 is connected to the first end of the second part 7022.

[0051] The second part 7022 extends from above the inner cavity 708 to the other side of the rotating frame 701. The second end of the second part 7022 is provided with a slope 7022b, and the slope 7022b and the return spring 707 are located on both sides of the second part 7022.

[0053] Specifically, such as Figure 4 , Figure 6 As shown, the handle 703 is threadedly connected to the rotating frame 701 via the screw 709. The inclined surface of the end face 7031 of the handle 703 is tangent to the inclined surface 7022b of the blade holder 702. When the handle 703 is held and the rotating frame 701 is rotated, the blade holder 702 is pushed to rotate at a small angle under the action of the thread and the inclined surface of the handle.

[0054] like Figure 2 As shown, the top of the cable clamping base 3 has a first mounting groove 301, and the cable clamping assembly 6 is disposed in the first mounting groove 301.

[0055] Cable clamping assembly 6 includes a sleeve 601 and a push rod 602. The sleeve 601 consists of two interlocking parts (e.g., Figure 7 As shown, a cable slot 6011 for placing an RF cable assembly is provided at the center of the sleeve 601. A push rod 602 is disposed on the side wall of the first mounting groove 301, with one end abutting against the sleeve 601 and the other end penetrating through the side wall of the first mounting groove 301. Tightening or loosening the sleeve 601 by rotating the push rod 602 allows for clamping or loosening of the RF cable assembly inside the sleeve 601. The push rod 602 is threadedly connected to the side wall of the first mounting groove 301.

[0056] Optionally, a guide rail 2 is provided on the base 1, and a slider 5 adapted to the guide rail 2 is provided at the bottom of the cable clamp 3. The fixing seat 4 is located at the right end of the guide rail. In order to prevent the cable clamp 3 from damaging the blade 706 when it slides to the right, a positioning block 8 can be provided on the cable clamp 3.

[0057] Optionally, the sleeve 601 and the inner cavity 708 are coaxially arranged; the fixed seat 4 is provided with a second mounting groove 401, and the bearing is located in the second mounting groove 401.

[0058] The cable clamp 3 is mounted on the base 1. The sleeve 601 is coaxially arranged with the inner cavity 708, so that the cable mounting axis is coaxial with the rotation axis of the rotating frame 701. The sleeve 601 is used to clamp the RF cable assembly with the bushing welded on. The cable clamp 3 can slide left and right on the guide rail 2 to adjust the gap between the blade 706 and the bushing.

[0059] Optionally, the first part 7021 has a blade mounting groove 7021a at its end, and the blade is disposed in the blade mounting groove 7021a. In the non-operating state, the blade 706 should be tangent to the outer surface of the RF cable assembly.

[0060] The first end of the second part 7022 is provided with a screw hole 7022a, a shoulder screw 704 is provided in the screw hole 7022a, and a bearing cover 705 is provided on the bearing.

[0061] The fixed base 4 is fixed on the base 1. A bearing is installed in the second mounting slot 401. The rotating frame 701 is installed in the inner hole of the bearing and can rotate freely. One end of the blade holder 702 is installed on the outer end face of the rotating frame 701 by a shoulder screw 704. The blade holder 702 can rotate at a small angle around the shoulder screw 704 in the inner cavity 708 of the rotating frame 701. The blade 706 is installed in the blade mounting slot 7021a at the left end of the blade holder 702. When the blade holder 702 rotates at a small angle, it drives the blade 706 to approach or move away from the center of the rotating frame 701, so as to cut the excess solder and cable shielding layer at the bushing. The inclined surface of the end face 7031 of the handle 703 is tangent to the inclined surface 7022b of the blade holder 702. When the handle 703 is held and the rotating frame 701 is rotated, the blade holder 702 is pushed to rotate at a small angle by the thread and the inclined surface of the handle.

[0062] The working principle of the RF cable assembly bushing cutting device provided by this utility model is as follows: The RF cable assembly with the bushing soldered is clamped into the cable clamping seat, and the cable clamping seat is pushed to the right so that the end face of the bushing is flush with the side of the blade; the handle is held and rotated clockwise, and the rotating seat drives the blade holder and the blade to make a circular motion while the blade approaches the center of the RF cable assembly, gradually cutting off the excess solder. After rotating several times, the excess solder and the cable shielding layer are cut off; the handle is rotated counterclockwise, and the blade holder drives the blade away from the axis under the action of the return spring (coil spring); the RF cable assembly is removed, and the cutting is completed.

[0063] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application.
