Description

Technical Field

[0001] The utility model relates to the data line field technology, in particular to a non-SR type anti-loosening braided data line. Background Art

[0002] Data cables generally include a wire body and two connectors connected to both ends of the wire body. Although the industry currently has very mature technology for making data cables, the wire body will be pulled when the data cables are actually used. How to prevent the wire body from being damaged or even loose is an issue that the industry needs to pay attention to. In addition, product miniaturization and thinning have always been issues of concern to users. In actual production and processing, how to improve the controllability of the production process and increase product yield is still the pursuit of technical personnel in the industry.

[0003] CN 115603147 A manufacturing process of ATYPE-C data cable, the manufacturing process comprises the following steps: S001: welding and fixing the pins of TYPE-C connector on the pads on the PCB board to form a TYPE-C connector module for standby use; S002: cutting a section of wire material to a fixed length, making a plastic shell, and sleeve the plastic shell on the outer periphery of the wire material; S003: stripping the outer coating of the wire end to reveal a plurality of wires, and dividing the wires, and then positioning the wires by low-pressure injection molding of wire positioning glue, and then stripping the wires to reveal the metal core wires, and finally butting the metal core wires with the soldering points of the PCB board and welding them to conduct; S004: molding a protective rubber core on the outer periphery of the PCB board, and the protective rubber core also wraps the wires and their metal core wires; S005: assembling a shielding shell, the shielding shell comprising a protective rubber core, a wire positioning glue and a rear end of the TYPE-C connector; S006: A hard rubber block is formed at the end of the wire, and the hard rubber block also wraps the rear end of the shielding shell; S007: the plastic shell is pushed relative to the wire, so that the plastic shell sequentially covers the hard rubber block, the shielding shell and the rear end of the TYPE-C connector to form a semi-finished product, wherein a plurality of bone positions in the plastic shell are tensioned and positioned with the hard rubber block, so that a first gap is formed between the plastic shell and the hard rubber block, the shielding shell and the rear end of the TYPE-C connector, and a second gap is formed between the hole position of the plastic shell and the wire, and then the semi-finished product is placed in a beer-covering mold, and a soft rubber liquid is injected into the inside of the plastic shell through the second gap to form a soft rubber colloid, which fixes the plastic shell with the hard rubber block, the shielding shell and the rear end of the TYPE-C connector as one; the rear end of the soft rubber colloid passes through the second gap between the plastic shell and the outer periphery of the wire to extend out of the rear end of the plastic shell to form an SR head, and the SR head is fixed integrally with the plastic shell and the wire.

[0004] However, the protective rubber core and hard rubber block are arranged in sections, and the plastic shell is only tensioned and positioned by the bone position and the hard rubber block. A gap needs to be reserved between the plastic shell and the entire semi-finished product as a subsequent soft rubber molding space. In other words, most of the area between the plastic shell and the entire semi-finished product is sandwiched by the soft rubber colloid, and the wire and the plastic shell are prone to loosening. If the soft rubber colloid is relied upon to provide sufficient anti-separation force, the thickness of the soft rubber colloid needs to be designed to be thicker. Combined with the thickness of the SR head, the overall size of the product is larger, which is not conducive to the thin and miniaturized design of the product. Moreover, for orders that specifically specify braided data cables, the junction of the braided wire and the soft rubber colloid will inevitably bend when used multiple times, which can easily lead to the separation of the braided wire and the soft rubber colloid, affecting the appearance of the product. Users believe that this is a product quality issue, which will increase the number of after-sales customer complaints.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

A groove 261 is formed on the outer peripheral side of the insulating outer mold 26 near the head end.

[0041] Step 8, apply hot melt glue on the insulating outer molds 26 at both ends respectively; usually, the hot melt glue application operation is automatically completed using a glue dispensing machine; the glue application location can be flexibly set, and can be part or all of the outer surface, usually at least on the rear end and the rear area of ​​the peripheral side of the insulating outer mold 26, so that after the outer shell 27 is pushed into place, there will be no glue overflow at the front end.

[0042] Step 9, assemble the shells 27 by pushing the two ends; push the two shells 27 toward the corresponding insulating outer mold 26 until the shells 27 are completely fitted and positioned outside the insulating outer mold 26; after the two shells 27 are pushed toward the corresponding insulating outer mold 26, the protrusions 273 are inserted into the corresponding grooves 261.
