Description

Technical Field

[0001] The present invention relates to the technical field of transmission lines, and in particular to a transmission line structure and a manufacturing process. Background Art

[0002] Some specifications of transmission lines require a braided layer 940 to be coated on the transmission line body 910. Generally, during the manufacturing process, after the transmission line body 910 is prepared, the braided layer 940 is directly coated on the transmission line body 910, and then the electrical connection body 930 is connected to the transmission line body 910, and the outer shell 920 is placed on the electrical connection body 930 and one end of the transmission line body 910. At this time, the outer shell 920 can be pressed against the braided layer 940 to make it close to the outer wall surface of the transmission line body 910. The specific structure is as follows: Figure 1 shown.

[0003] However, the braided layer 940 mainly serves the purpose of shielding and identification. Different customers have different requirements for the shielding parameters of the transmission line or the identification patterns formed by the braided layer 940. The manufacturer can stock a large number of transmission line bodies 910, but must wait until the customer confirms the relevant requirements before the manufacturer can proceed with the steps of covering the braided layer 940, connecting the electrical connection body 930, and installing the outer shell 920. This is time-consuming and difficult to meet customer needs. Summary of the Invention

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0034] like Figure 2 -4 shows a transmission line structure according to an embodiment of the first aspect of the present invention, including a plug assembly 100 and a transmission line assembly 200, the plug assembly 100 includes an electrical connection body 110 and an outer shell 120 sleeved on the electrical connection body 110, the outer shell 120 is provided with a wiring port 121, the transmission line assembly 200 includes a transmission line body 210, a braided layer 220 covering the transmission line body 210 and a pressure ring 230, one end of the transmission line body 210 is passed through the wiring port 121 to enter the outer shell 120, and one end of the transmission line body 210 is connected to the electrical connection body 110, and the pressure ring 230 is sleeved on a portion of the braided layer 220 so that the braided layer 220 is pressed against the outer wall surface of the transmission line body 210.

[0035] The electrical connection body 110 generally includes a guide pin seat and a plurality of guide pins passing through the guide pin seat. The guide pins can be connected to external circuits to transmit signals or supply power.

[0036] The outer shell 120 is generally made of metal and can play a supporting and signal shielding role. The transmission line body 210 can have various structures, for example, including multiple conductors, each conductor surface is covered with a first insulating outer skin, and then covered with a second insulating outer skin. It is not specifically limited here. The connection between one end of the transmission line body 210 and the electrical connection body 110 means that each conductor is electrically connected to the guide pin according to actual needs. The outer shell 120 is mounted on one end of the transmission line body 210 and the electrical connection body 110, and the internal gap can be injected with resin or other materials for packaging.

[0037] Specifically, in an actual finished product, the outer surface of the outer shell 120 may also be covered with an outer shell mold made of resin, plastic or other materials.

[0038] The braided layer 220 is interwoven with multiple braided wires, and the braided wires can be made of nylon, metal, etc. Different materials and the combination and proportion of different materials can form different shielding parameters. Different braided wires can use different colors and changing the braiding order can form different braiding patterns, as different identifications, etc. Therefore, before actual delivery, customers can provide the required braided layer 220 parameters, and manufacturers need to refer to the braided layer 220 parameters to process and produce the transmission line.

[0039] In the transmission line structure of the present invention, the pressure ring 230 can press the braided layer 220 against the outer wall surface of the transmission line body 210, so that the braided layer 220 will not deviate from the surface of the transmission line body 210, and the connection is firm and stable. Based on this structure, when processing and manufacturing the transmission line, the manufacturer can first produce the transmission line body 210, connect one end of the transmission line body 210 to the electrical connection body 110, and then put the outer shell 120 on the electrical connection body 110 and part of the transmission line body. At this time, the semi-finished transmission line can be used for inventory. After the customer provides the specification requirements of the braided layer 220, the manufacturer will weave the braided layer 220 of the corresponding specifications on the outer wall surface of the transmission line body 210, and then fix it with the pressure ring 230. This design flexibly changes the transmission line structure, thereby changing the production and manufacturing process, shortening the delivery time, and improving production flexibility.

[0040] In some embodiments of the present invention, there are two plug assemblies 100, each located at the two ends of the transmission line body 210 (not shown in the figure). The two plug assemblies 100 can be used to connect to different devices to achieve signal transmission or power supply.

[0041] In some embodiments of the present invention, there are two pressing rings 230 , each located at two ends of the transmission line body 210 , so that both ends of the braided layer 220 on the transmission line body 210 will not deviate toward the other end.

[0042] The manufacturing process according to the second embodiment of the present invention includes the following steps: preparing a transmission line body 210 and connecting one end of the transmission line body 210 to the electrical connection body 110; placing an outer shell 120 over the electrical connection body 110 and one end of the transmission line body 210 to form a semi-finished transmission line; forming a braided layer 220 on the outer wall surface of the transmission line body 210; and placing a pressure ring 230 over a portion of the braided layer 220 so that the braided layer 220 presses against the outer wall surface of the transmission line body 210.

[0043] It should be noted that the transmission line body 210 generally includes a conductor and an insulating sheath covering the conductor, and may also have other structures. Manufacturers can process it according to actual needs. The actual process of preparing the transmission line body 210 will be appropriately changed according to the specific structure of the transmission line body 210, and is not specifically limited here.

[0044] Specifically, one end of the transmission line body 210 is connected to the electrical connection body 110, and the outer shell 120 is put on the electrical connection body 110 and one end of the transmission line body 210 to form a semi-finished transmission line. It can be understood that each conductor is electrically connected to the guide pin according to actual needs. The outer shell 120 can be processed by stamping or other processes to be put on one end of the transmission line body 210 and the electrical connection body 110, and the internal gap can be injected with resin or other materials for packaging.

[0045] According to the manufacturing process of the present invention, the manufacturer can first prepare the transmission line body 210, connect one end of the transmission line body 210 to the electrical connection body 110, and then put the outer shell 120 on the electrical connection body 110 and part of the transmission line body. At this time, the semi-finished transmission line can be used for inventory. After the customer provides the specification requirements of the braided layer 220, the manufacturer will then weave the braided layer 220 of the corresponding specifications onto the outer wall surface of the transmission line body 210, and then fix it with a pressure ring 230. This design transforms the production and manufacturing process, shortens the delivery time, and improves production flexibility.

[0046] In some embodiments of the present invention, there are two electrical connection bodies 110 and two outer shells 120 , which are connected to the two ends of the transmission line body 210 in a one-to-one correspondence to form a semi-finished transmission line (not shown in the figure).

[0047] It should be noted that the semi-finished transmission lines here can be used for inventory. Generally speaking, customers will only make relevant requirements on the shielding specifications and markings to be achieved by the braided layer 220, and the transmission parameters of the transmission line itself can be pre-set, so that the semi-finished transmission lines can be produced in large quantities in advance. After the customer provides the specification requirements of the braided layer 220, the semi-finished transmission lines can be used to further process the braided layer 220, shortening the time for later processing and improving supply efficiency.

[0048] In some embodiments of the present invention, the braided layer 220 is interwoven by multiple braided wires. Specifically, in the processing technology of the braided layer 220, the wires are generally placed in a braiding machine, wherein the braiding machine generally includes a base frame, a traction mechanism and a plurality of nested support ring disks. The support ring disks can be rotatably set on the base frame, and the wires to be woven can be placed in the middle of the support ring disks. Each support ring disk is provided with a plurality of winding rollers around the periphery of the wires to be woven, and each winding roller is wound with a braided wire. At this time, according to customer needs, the braided wires can be set on different winding rollers as required. The traction mechanism can be a roller, which is generally located above the support ring disk. One end of the wire can be wound on the roller. The roller is driven by a motor or other driving component, so that the traction mechanism can drive the wire to move, and the braided wire can be set on the surface of the wire. The support ring disk rotates and cooperates with the traction mechanism to drive the wire to move, so that the braided wire can be woven on the surface of the wire.

[0049] In some embodiments of the present invention, in the step of forming the braided layer 220 on the outer wall surface of the transmission line body 210, the manufacturer can arrange multiple transmission line semi-finished products end to end, and let the multiple transmission line semi-finished products pass through the braiding machine in sequence, so that the braided layer 220 is braided on the outer surface of each transmission line semi-finished product in sequence. Figure 3 As shown, the excess braided layer 220 is then processed. This step greatly improves the processing efficiency.

[0050] Specifically, after braiding a plurality of semi-finished transmission line products arranged end to end based on the above steps, a pressure ring 230 can be provided at both ends of the transmission line body 210. Then, the manufacturing process further includes: cutting the braided layer 220 between the pressure ring 230 and the adjacent outer shell 120 to remove the braided layer 220 between the two adjacent transmission line bodies 210.

[0051] There are many ways to cut the braided layer 220 here, such as cutting with a knife. In some embodiments of the present invention, the braided layer 220 between the pressure ring 230 and the adjacent outer shell 120 can be heat-melted to cut the braided layer 220. The heat-melting treatment can improve efficiency. In addition, the braided layer 220 after heat melting can also be adhered to the outer surface of the transmission line body 210 to make the connection more stable.

[0052] Specifically, the hot melt treatment may involve placing a heated metal block close to the braided layer 220 to break it.

[0053] In some embodiments of the present invention, the metal strip may be bent around the circumference of the transmission line body 210 to form the pressure ring 230 , which is more convenient to process and easier to implement.

[0054] Specifically, a movable mold and a fixed mold can be used to cooperate to squeeze the metal strip placed at a suitable position of the transmission line body 210, so that the metal strip is bent and deformed to form the pressure ring 230. This process is fast and improves processing efficiency.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
