Description

Technical Field

[0001] The utility model relates to the technical field of tooling and fixtures, in particular to a cable tinning tooling. Background Art

[0002] Cables (including but not limited to coaxial cables) after stripping the outer sheath often need to be tinned, and some tinned cables also need to be bent. When the inner bending radius of the cable is less than 2.0mm, the cable yield will be greatly reduced due to the poor ductility of tin, limiting the design of application-end products. When some application-end products have a small space for placing cables and cannot meet the requirements of the minimum bending radius of the cable, the industry will sacrifice the cable yield for production, resulting in high production costs. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a cable tinning tool which can improve the manufacturing yield of cables with bending sections.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cable tinning tool, comprising:

[0005] A positioning plate, wherein a plurality of positioning grooves for positioning cables are provided on the positioning plate, wherein the positioning grooves include a blind groove section and a through groove section that are connected to each other, wherein the through groove section has at least one bending portion, and wherein a plurality of groups of hollow structures are further provided on the positioning plate, wherein each group of the hollow structures includes two hollow grooves that are arranged opposite to each other, and the through groove section is located between two of the hollow grooves in the hollow structure and is connected to the two hollow grooves respectively;

[0006] An intermediate plate, the intermediate plate is located below the positioning plate, the intermediate plate is provided with a through slot and a plurality of positioning blocks, the positioning blocks are arranged corresponding to the hollow slots, and the through slots are arranged corresponding to the through slot sections;

[0007] A base plate is located below the middle plate, and is provided with ejection ribs corresponding to the through slot segments and an elastic abutting component for abutting the positioning plate.

[0008] In one embodiment, the middle plate has a through hole for the elastic abutting component to pass through.

[0009] In one embodiment, there are multiple elastic abutting components.

[0010] In one embodiment, the elastic abutting assembly includes a spring and an ejector pin which is movably disposed on the substrate, and the spring contacts the ejector pin and the substrate respectively.

[0011] In one embodiment, a positioning column is provided on the middle plate, and a positioning hole cooperating with the positioning column is provided on the positioning plate.

[0012] In one embodiment, the through-slot section and the ejection rib are both in a broken line shape.

[0013] In one embodiment, there are multiple positioning grooves on the positioning plate.

[0014] In one embodiment, a plurality of the positioning grooves are arranged in at least one row.

[0015] In one embodiment, a plurality of groups of the hollow structures are correspondingly provided to a single through slot segment.

[0016] The beneficial effect of the utility model is that when the staff operates, they first stack the base plate, the middle plate and the positioning plate in sequence from bottom to top, and then place the cable into the positioning groove. The positioning block inserted into the hollow groove can make the cable in the through groove section more accurately positioned, and then press the middle plate to make the positioning block withdraw from the hollow groove, and the positioning plate is separated from the middle plate. With the assistance of the ejection ribs, the area of ​​the cable in the through groove section can still be well maintained in the through groove section. Finally, the removed positioning plate and the cable positioned by it are placed in the tin bath to tin the cable. During the tinning process, the presence of the hollow groove allows the tin liquid to flow fully, and there is more contact area between the tin liquid and the cable, thereby improving the tinning effect of the cable.

[0017] Compared with the prior art of tinning first and then bending, the bending radius of the cable tinning operation performed using the present cable tinning tool can be made smaller without the risk of cracking, and the production yield is higher. Bending first and then tinning saves work stations and has lower production costs than the process of tinning first and then bending. In addition, in the post-bending process, since the cable rebounds after bending, the bending tolerance is large and the shape is difficult to control, while the tolerance of the cable tinned using the present cable tinning tool is easier to control.
