Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency cable core stripping devices, in particular to a radio frequency cable core flat cross-section stripping tool. Background Art

[0002] In RF switches, sintered insulators are often used to connect RF boards with upper and lower layers, but they are expensive to use. In actual operation, the RF cable core can replace the insulator, and the core can be used by stripping the ends of the core to a predetermined length using wire strippers. Existing wire strippers can adjust the stripping length as needed, but there are two problems. First, there is the problem of the insulation material being squeezed and deformed at the stripping point of the core, and the circular flat cross-section becomes an irregular convex cross-section. This deformation will prevent the core from passing through the corresponding vias on the RF switch cavity, reducing assembly efficiency. Second, the stripping effect on flexible cable cores is poor. Not only is there the problem of the insulation material being squeezed and deformed at the stripping point of the core, but there is also the problem of the core being twisted as a whole.

[0003] Therefore, providing a stripping tool that can strip a circular flat cross-section of both rigid and flexible RF cable cores and can adjust the stripping length has become a technical problem that urgently needs to be solved in this technical field. Utility Model Content

[0027] Specifically, the connecting rod 7 is a block-shaped structure that is approximately rectangular, and a cavity is opened inside the connecting rod 7, one end of which is open. A loading platform for placing the wire core is provided at the end of the connecting rod 7 away from the cavity, and a hole is extended into the interior of the connecting rod 7 at one end of the loading platform. The hole allows the wire core to be inserted, so that the length of the wire core fed in can be adjusted to adjust the length of the wire to be stripped.

[0028] The knife clamping slider 8 is specifically a slider and a blade for cutting arranged at the bottom of the slider.

[0029] The device provided by the present invention mainly includes a base 3 and a wire pressing device, a wire stripping device and a power device arranged on the base 3. The wire stripping device includes a cutter, a knife clamping slider 8, a connecting rod 7 and a sliding device.

Through the above device, when in use, the wire core is fixed by the wire pressing device, and the upper and lower heights of the knife clamping slider 8 are adjusted by the sliding device. The length of the wire core fed into the wire stripping device is adjusted to achieve the length of the wire to be stripped.

Through the above device, the wire core will not be squeezed when stripping, and the entire process of ring cutting makes the circular flat cross-section regular, which improves the wire stripping effect to a certain extent.

The stripping length can be adjusted through the hole extending from one end of the stage into the connecting rod 7. Rotate the screw column 9 to move the clamping knife slider 8 downward to the specified position and cut into the wire core. At this time, the cutting edge of the cutter is tangential to the circular metal core of the wire core. The connecting rod 7 of the stripping part is fixed to the power part through the anti-rotation shape and screws, and rotates synchronously with the transmission shaft. Lower the pressure block 1 to press the cable to prevent the stripping part from rotating and causing the wire core to rotate during stripping. Drive the handle 6, and the cutter will rotate around the metal core of the wire core. After one rotation, the insulation layer covering the metal core of the wire core can be cut radially. The cut surface is flat and there is no extrusion deformation.
