Description

Technical Field

[0001] The utility model relates to the technical field of high-speed cables, in particular to a laser cutting jig for high-speed cables. Background Art

[0002] High-speed cable is a low-cost short-distance connection cable for data transmission. It is widely used in data center interconnection scenarios such as SATA storage devices, RADI system scenarios, core routers, Ethernet, etc. As a high-speed and stable data transmission medium, high-speed cable has brought great convenience to people's work and life. High-speed cable generally includes a cable body and a connector connected to the end of the cable. According to different transmission protocols, common high-speed cables include SFP, QSFP, OSFP, SAS and other types. In the production process of high-speed cable, it is necessary to combine and connect the high-speed parallel line cable and the corresponding connector, that is, to connect the high-speed parallel line inside the cable to the corresponding connector. The high-speed parallel line needs to be cut before connection to remove the aluminum foil layer wrapped around the periphery. According to the design requirements of the product, the cutting process does not require the complete removal of the aluminum foil layer, but only needs to cut to form a window smaller than the diameter of the high-speed parallel line. At present, the cutting operation of the aluminum foil layer of the high-speed parallel line is generally performed by laser, but because the diameter of the high-speed parallel line itself is small and positioning is difficult, it is easy to exceed the cutting range during the laser cutting process, affecting the quality of subsequent products.

DETAILED DESCRIPTION

[0022] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0023] Reference Figures 1 to 3 The present embodiment provides a laser cutting jig for high-speed cables, including a base, a cable positioning mechanism disposed on the base, a cable fixing mechanism disposed on the base, and a cable clamping assembly disposed on the cable fixing mechanism.

[0024] The cable positioning mechanism includes a positioning seat connected to the base, a positioning cover rotatably connected to the positioning seat, the top surface of the positioning seat is recessed downward to form a concave platform, the concave platform is evenly provided with a plurality of positioning strips, and the plurality of positioning strips divide the concave platform into a plurality of receiving grooves for accommodating cables, and the positioning cover is provided with openings corresponding to the receiving grooves, and a pressure strip matching the positioning strip is formed between adjacent openings. In this embodiment, there are three positioning strips, forming four receiving grooves, and four cables can be placed at the same time. After the positioning cover is closed, the opening portion is the area through which the laser can pass, so that during the cutting process, the laser will not cut the portion of the cable outside the area, thereby ensuring the accuracy of the cutting position.

[0025] The positioning seat is provided with a plurality of first permanent magnets, and the positioning cover is made of ferromagnetic material. After the positioning cover is closed, the first permanent magnets absorb the positioning cover to prevent the positioning cover from moving.

[0026] The top surface of the positioning seat is provided with a first positioning column, and the positioning cover is provided with a positioning hole matching the first positioning column. The positioning cover is a rotating connection, so a rotation space needs to be reserved at the connection, so that the positioning cover may be offset along the axial direction of the rotating shaft. The cooperation of the first positioning column ensures that the positioning cover is in a set position after closing.

[0027] The cable fixing mechanism comprises a fixing seat connected to the base, a fixing cover plate with one end rotatably connected to one end of the fixing seat, and a spring telescopic buckle arranged at the other end of the fixing seat for locking the fixing cover plate.

[0028] A boss is arranged at the end of the top surface of the fixing seat, the spring extension buckle is arranged on the boss, and the fixing cover plate is provided with a buckling portion corresponding to the boss.

[0029] A plurality of second permanent magnets are arranged on the boss, and the fixed cover is made of ferromagnetic material or at least the buckling part is made of ferromagnetic material. After the fixed cover is closed, the second permanent magnets adsorb the fixed cover, and then the spring telescopic buckle is pressed to lock the fixed cover, so that the cable clamping assembly on the fixed seat can be locked and fixed to avoid displacement of the cable during laser cutting.

[0030] The cable clamping assembly includes a clamping seat, a clamping plate connected to the clamping seat, the clamping plate is connected to one end of the clamping seat, and the other end of the clamping seat is provided with a clamping member for clamping the clamping plate. The clamping member and the clamping seat are rotatably connected. After the clamping plate is closed, the clamping member is rotated, and the clamping member contacts the upper end surface of the clamping plate and squeezes the clamping plate, pressing the clamping plate onto the clamping seat (such as Figure 3 as shown).

[0031] Both ends of the clamping seat are provided with positioning notches, and the fixing seat is provided with a second positioning column matching the positioning notches. The clamping seat and the fixing seat are detachable structures, and two second positioning columns are provided, corresponding to the two positioning notches respectively, so that after the cable clamping assembly is placed on the fixing seat, it is restricted to the set position. At this time, the cable clamped by the cable clamping assembly can accurately correspond to the receiving groove of the cable positioning mechanism, so that the cable can quickly enter the receiving groove. Since the cable clamping assembly is detachably connected, several cable clamping assemblies can be used when performing laser cutting operations, and the cables are pre-arranged and clamped. After each laser cutting operation is completed, a new cable to be cut can be quickly replaced, which greatly improves the efficiency of laser cutting.

[0032] The clamping seat is provided with a plurality of grooves for placing cables. Multiple cables can be evenly arranged on the clamping seat. The plurality of grooves correspond to the accommodating grooves one by one, so that after the cables are placed in the grooves, the positions of the cables can correspond to the positions of the accommodating grooves.

[0033] The positioning seat is provided with a plurality of waist-shaped holes, and fasteners pass through the waist-shaped holes to fix the positioning seat to the base. In specific implementation, the positioning seat can be adjusted to a suitable position and then fixed by fasteners (that is, the distance between the positioning seat and the fixing seat can be adjusted) to meet the requirements of different cutting positions of the cable.

[0034] When the utility model is in use, it can be placed on the workstation of the laser equipment. First, the high-speed parallel line is clamped on the cable clamping assembly, and then the cable clamping assembly is installed to the corresponding position of the fixed seat of the cable fixing mechanism. At this time, the cable enters the receiving groove of the cable positioning mechanism, and then the positioning cover and the fixed cover plate can be closed, and the laser equipment can start the cutting operation. After the cutting is completed, the fixed cover plate and the positioning cover are opened, the cable clamping assembly is taken out, and another cable clamping assembly is replaced. In this embodiment, two cable positioning mechanisms are provided on the base, and two cable clamping assemblies can be placed correspondingly on the fixed seat. In addition, the utility model is not limited to the application in the cutting of SAS lines. If other types of cables have the same cutting requirements, the laser cutting jig provided by the utility model can also be used.

[0035] The opening of the positioning cover and the positioning seat receiving groove of the utility model can ensure that only the aluminum foil in the set area is cut during the laser cutting process, ensure the accuracy of the cutting position, ensure the cutting quality, and thus ensure the quality of the product. On the other hand, the cable clamping assembly and the fixing seat are detachably connected, so that the cable can be pre-clamped in the cable clamping assembly and then placed in the cable fixing mechanism and the cable positioning mechanism for cutting, shortening the processing interval and improving the laser cutting efficiency.
