Description

Technical Field

[0001] The utility model relates to the data line field technology, in particular to a data line for preventing SR from loosening. Background Art

[0002] A data cable generally includes a wire body and two connectors connected to both ends of the wire body. An SR is provided at the end of the wire body. Considering the use requirements of the SR, it is usually designed to be made of soft rubber material. During actual molding, the adhesion between the SR soft rubber and the insulating outer mold (hard rubber) of the connector is not ideal. After long-term use, the SR is prone to loosening or even falling out.

[0003] CN115603147A discloses a manufacturing process of a TYPE-C data cable, which includes the following steps: S001: welding and fixing the pins of the 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 periphery of the wire material; S003: stripping the outer coating of the wire end to reveal multiple 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 connecting the metal core wires with the solder joints of the PCB board and welding them to conduct; S004: forming a protective rubber core on the periphery of the PCB board, and the protective rubber core also wraps the wires and their metal core wires; S005: assembling a shielding shell, which includes a protective rubber core, a wire positioning glue and a rear end of the TYPE-C connector ; S006: forming a hard rubber block at the end of the wire, and the hard rubber block also wraps the rear end of the shielding shell; S007: pushing the plastic shell 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 the multiple 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-wrapped mold, and the soft rubber liquid is injected into the inside of the plastic shell through the second gap to form a soft rubber colloid, which makes the plastic shell and the hard rubber block, the shielding shell and the rear end of the TYPE-C connector fixed 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. That is to say, 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-slip force, the thickness of the soft rubber colloid needs to be designed to be thicker, and the area of ​​the soft colloid is larger and the amount used is larger. In order to better meet the requirements of bending the wire ends and ensuring that the SR head is not easily aged and damaged in an exposed environment, the selected soft colloid has a higher cost, which will undoubtedly increase the product cost.

[0005] Moreover, this manufacturing process has many steps, which makes the manufacturing process complicated and is not conducive to the control of production costs and finished product yield.

[0006] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

A PCB board or a tail end extension board is provided at the tail end of the core 211, and the end of the wire 10 is welded to the CB board or the tail end extension board. A UV glue part is provided at the welding point between the wire 10 and the connector 21, and the UV glue part wraps and fixes the welding point.

[0036] The insulating inner mold 22 is fixed to the tail end of the metal shielding shell 212 by one-time injection molding, and the insulating inner mold 22 wraps the corresponding outer tail end of the metal shielding shell 212, and the insulating inner mold 22 fills the inside of the metal shielding shell 212 to be fixed to the inner surface of the metal shielding shell 212 and the end of the wire 10 and the welding point; the tail end of the insulating inner mold 22 has a first anti-slip joint 221. The first anti-slip joint is provided with any one or more of a step, a hole 222, a slot, and a rib. Usually, a notch is reserved on the surface of the metal shielding shell 212, and the rubber of the insulating inner mold 22 is filled into the reserved notch on the metal shielding shell 212.

[0037] The SR23 is fixed on the first anti-slip joint 221 and the wire 10 adjacent to the first anti-slip joint 221 by secondary injection molding. The SR23 includes a second anti-slip joint 231 and a wire protection part 232 that are integrally connected. The second anti-slip joint 231 is combined and fixed to the first anti-slip joint 221, and the wire protection part 232 is wrapped around the outside of the wire 10 adjacent to the first anti-slip joint 221 and combined and fixed.

[0038] The insulating outer mold 24 is fixed to the outside of the insulating inner mold 22 and the SR 23 by three injection moldings, and the insulating outer mold 24 wraps the outer periphery of the insulating inner mold 22 and the outer periphery and tail end of the second anti-slip joint 231.

The tail end of the insulating outer mold 24 exceeds the tail end of the second anti-slip joint 231, and a tail end stopper 242 is formed outside the tail end of the second anti-slip joint 231.

[0039] Next, a manufacturing process for a data line to prevent SR from loosening is introduced, including the following steps:

[0040] Step 1, prepare the wire 10 and two connectors, and weld the two connectors to the two ends of the wire 10 respectively; both connectors are male connectors or female connectors, or one is a male connector and the other is a female connector. Among the two connectors, one is any one of a TYPE-C connector, a USB-A connector, a MICRO USB connector, and a Lighting connector, and the other is any one of a TYPE-C connector, a USB-A connector, a MICRO USB connector, and a Lighting connector. For example: both connectors are TYPE C connectors, or one connector is a TYPE-C connector and the other connector is a USB-A connector, or one connector is a MICRO USB connector and the other connector is a USB-A connector. When actually designing and manufacturing, different connector types can be freely combined and matched according to product needs. In this embodiment, the two ends are respectively TYPE-C connector 21' and USB-A connector 21 as an example for explanation. The connector includes a core 211 and a metal shielding shell 212 wrapped around the outside of the core 211. The metal shielding shell 212 of the USB-A connector 21 is integrated, while the metal shielding shell of the TYPE-C connector 21' includes a front metal shell and a rear metal shell 211' which are designed separately and then assembled and fixed by welding. The tail clamp 213 of the metal shielding shell 212 of the USB-A connector 21 is fixed on the wire 10; the welding point between the wire 10 and the connector is arranged on the PCB board 212' at the tail end of the connector or on the tail end extension board of the connector; after welding, UV glue is sprayed on the welding point and cured to form a UV glue part, and the UV glue part wraps and fixes the welding point. Specifically, when spraying glue, a UV glue part of a preset shape, size and area is formed on the PCB board or the extension board by a carrier, and it is cured by a UV curing machine. The UV glue part fully covers the solder joints at the welding point, and the solder joints will not loosen, and the waterproof effect is good. The welding points between the wire 10 and the two connectors are hidden in the metal shielding shells 212 of the corresponding connectors; usually, the outer surface of the wire 10 is rubber, which has good adhesion with SR.

[0041] Step 2, perform injection molding once at both ends respectively; perform injection molding once at the tail end of the metal shielding shell 212 to obtain an insulating inner mold 22; the insulating inner mold 22 wraps the corresponding outer tail end of the metal shielding shell 212, and the insulating inner mold 22 fills the inside of the metal shielding shell 212 to be combined and fixed to the inner surface of the metal shielding shell 212 and the end of the wire 10 and between the welding points; and the insulating inner mold 22 wraps and is fixed to the outside of the tail end clamp 213. The tail end of the insulating inner mold 22 has a first anti-slip joint 221; the outer dimensions of the first anti-slip joint 221 can usually be designed to be slightly smaller than the main body of the insulating inner mold 22, that is: an annular groove is formed on the outer periphery of the first anti-slip joint 221; the first anti-slip joint 221 is provided with any one or more of a step, a hole, a slot, and a rib; for example: the first anti-slip joint 221 of the USB-A connector is provided with two holes 222 arranged at left and right intervals and passing through the first anti-slip joint 221 from top to bottom. The first anti-slip joint 221' of the TYPE-C connector is provided with a hole 222', a slot 223', and a step 224'. On the TYPE-C connector, a convex portion 221' is also formed on the insulating inner mold 22' near the head end, which is conducive to improving the stability of the subsequent insulating outer mold 24' and the insulating inner mold 22'.

[0042] Step 3, perform secondary injection molding on both ends respectively; perform secondary injection molding on the first anti-slip joint 221 and the wire 10 adjacent to the first anti-slip joint 221 to obtain SR23; the SR23 includes a second anti-slip joint 231 and a wire protection part 232 connected in an integral manner, the second anti-slip joint 231 is combined and fixed with the first anti-slip joint 221, and the second anti-slip joint 231 is filled in the annular groove to form a fully wrapped fixation to the outer periphery of the first anti-slip joint 221, such as Figure 2 and Figure 4 As shown, the accommodating cavity 2311 and the positioning rib 2312 on the second anti-slip joint 231 of the USB-A connector are shaped to match the first anti-slip joint 221. The wire protection portion 232 is wrapped around the outside of the wire 10 adjacent to the first anti-slip joint 221 and fixed in combination; during secondary injection molding, the second anti-slip joint 231 is fixed in combination with the corresponding steps, holes, grooves, and ribs. The mutual combination of the second anti-slip joint 231 and the first anti-slip joint 221 can achieve mutual positioning in multiple directions such as up, down, left, right, front, and back, and will not get loose. On the TYPE-C connector, SR23' includes a second anti-slip joint 231' and a wire protection portion 232' that are integrally molded and connected.

[0043] Step 4, perform three injection molding at both ends respectively; perform three injection molding on the outside of the insulating inner mold 22 and the SR23 to obtain an insulating outer mold 24, which wraps the outer periphery of the insulating inner mold 22 and the outer periphery and tail end of the second anti-slip joint 231. The head end of the insulating outer mold 24 exceeds the head end of the insulating inner mold 22, and a head end stopper 241 is formed outside the head end of the insulating inner mold 22. The tail end of the insulating outer mold 24 exceeds the tail end of the second anti-slip joint 231, and a tail end stopper 242 is formed outside the tail end of the second anti-slip joint 231.

[0044] And, the insulating inner mold 22 is hard glue, and the SR 23 is soft glue. The insulating outer mold 24 can be hard glue, and its specific hardness is not limited to the insulating inner mold 22. It can be understood that the material of the insulating outer mold 24 and the insulating inner mold 22 can be the same or different. Further, a notch is reserved on the surface of the metal shielding shell 212. In step 2, the glue is filled into the notch reserved on the metal shielding shell 212 during one-time injection molding. For example, in a USB A connector, the notches on the metal shielding shell 212 include (but are not limited to) process openings, spring notches, etc. The springs are downwardly lower than the corresponding holes in the core of the connector. Therefore, the spring notches and the corresponding holes are interconnected. During one-time injection molding, the rubber fills the corresponding holes through the notches. Through one-time injection molding, the insulating inner mold 22 and the metal shielding shell 212 and the core (and components such as terminals on the core) can be well combined and fixed, which not only strengthens the stability of the combination between the insulating inner mold 22 and the connector, but also strengthens the positioning between several parts of the connector itself, and has good waterproof performance.

[0045] The manufacturing process of the data cable of the utility model is simple. At this point, the entire data cable is basically completed. Subsequent inspections are required, such as appearance inspection, fixture measurement, swing test, electrical testing, burning software, burning test, data cable function test, etc. Functional testing includes the use of electrical testing machines, actual mobile phone testing, and finished product CCD inspection, winding, labeling and / or QR code, and final product inspection.

[0046] The design focus of the utility model is that it mainly uses one-time injection molding to obtain the insulating inner mold 22, the insulating inner mold 22 wraps the outside of the tail end of the metal shielding shell 212 and fills the inside of the metal shielding shell 212, and the tail end of the insulating inner mold 22 reserves a first anti-detachment joint 221. In this way, during the secondary injection molding, secondary injection molding is performed on the first anti-detachment joint 221 and the wire 10 adjacent to the first anti-detachment joint 221 to obtain SR23; SR23 is stably combined with the insulating inner mold 22. The insulating outer mold 24 wraps the outer periphery of the insulating inner mold 22 and the outer periphery and the tail end of the second anti-slip joint 231, so that the SR23 can be effectively prevented from loosening. In addition, the amount of rubber used to mold the SR23 during the secondary injection molding is small, which is beneficial to controlling the material cost. Moreover, the manufacturing process steps are simple, the three-mold injection molding is carried out, the controllability is good, and the finished product yield is high.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
