[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Example 1: Please see Figure 1 and Figure 2 This utility model discloses a heavy-duty communication cable assembly, including a connector end 1 with a crimp terminal 11, which is crimped to the wire core 4 of the cable assembly; an inner mold 3, which is inserted into the connector end 1 and has a box structure. The inner mold 3 has a cavity for placing the cable assembly inside and a partition structure 31 with several rows of through holes for inserting and separating the wire core 4; and an outer mold 2, which is used to wrap the inner mold 3 and the connection part 13 between the inner mold 3 and the connector end 1. The inner mold 3 has a mesh tail 32 at the cable assembly outlet, which covers the cable assembly and connects to the outer mold 2.

[0023] Specifically, the heavy-duty communication cable assembly adopts a combination of inner mold 3 and outer mold 2. The connector end 1, used for electrical connection with external devices, has a crimp terminal 11 inside for crimping the wire cores 4 of the cable assembly, thus fixing the wire cores 4 on the crimp terminal 11 and preventing the cable assembly from loosening. The inner mold 3 and the connector end 1 are plugged into each other. The inner mold 3 is a box-shaped structure with open ends. The cable assembly passes through the inner mold 3. The inner mold 3 has a partition structure 31 inside to separate the wire cores 4 of the cable assembly. The partition structure 31 has several rows of perforations, which can be selected but not limited to two rows. The perforations allow each wire core 4 to use an independent channel, avoiding cross compression and also achieving the effect of straight cable exit.

[0024] In addition, an outer mold 2 is provided on the outside of the connector end 1 and the inner mold 3 to wrap the inner mold 3 and the connection part 13 with the connector end 1, which is used to reinforce the connection between the inner mold 3 and the connector end 1. The design of the outer mold 2 can also play a sealing role, so that the heavy-duty communication cable assembly can be used for a long time in a humid environment.

[0025] It is worth noting that the inner mold 3 has a mesh tail 32 at the cable outlet. The mesh tail 32 wraps around the cable assembly and is connected to the outer mold 2. The mesh tail 32 can distribute the tensile force to a longer cable assembly segment by extending the stress area, thus preventing the cable assembly from breaking when pulled. This allows the heavy-duty communication cable assembly to meet the requirements of dragging or long-term heavy-duty usage environments. The mesh tail 32 is located at the tail of the heavy-duty communication cable assembly to prevent fatigue fracture of the internal wire core 4 caused by frequent bending of the cable assembly.

[0026] In this embodiment, the heavy-duty communication cable assembly adopts a double-layer protective structure with inner and outer molds. The crimping terminal of the connector end 1 serves to fix the wire core 4 and prevent loosening. The partition structure 31 of the inner mold 3 is used to support and separate the wire core 4, so that the tensile force is evenly distributed. A mesh tail 32 is provided at the cable outlet. The mesh tail 32 is combined with the outer mold 2 to enhance the overall tensile strength of the heavy-duty communication cable assembly and meet the requirements of heavy-duty suspension scenarios.

[0027] Example 2: This embodiment represents a further structural optimization of the heavy-duty communication cable assembly of this utility model. Please refer to [link / reference]. Figure 1 and Figure 3 .

[0028] In some embodiments, the outer mold 2 includes a first end 21, a second end 22 and a middle region located between the first end 21 and the second end 22 along the length direction. The middle region forms a bend between the first end 21 and the second end 22, and an anti-slip texture 23 is provided between the two bends.

[0029] Specifically, the first end 21 of the outer mold 2 is connected to the connector end 1, covering the connection between the connector end 1 and the inner mold 3. The second end 22 of the outer mold 2 is connected to the tail 32, enhancing the tensile strength at the cable assembly outlet. Anti-slip texture 23 is provided in the middle area of ​​the cable, distributed in a circular direction to enhance surface friction and facilitate insertion and removal of the heavy-duty communication cable assembly by operators. The middle area extends outwards towards the first end 21 and the second end 22, forming corresponding bends. These bends act as reinforcing ribs of the outer mold 2, increasing the overall structural strength.

[0030] Understandably, the outer mold 2 can be made of a combination of soft and hard materials to achieve the corresponding functions in sections, or it can be made of a single material to meet the needs of practical applications.

[0031] In some embodiments, the crimp terminal 11 includes a pin 14, one end of which is a contact end and the other end is a crimp terminal.

[0032] Specifically, the crimp terminal 11 is electrically connected to an external device via the pin 14, and the contact end of the pin 14 extends to the side of the connector end 1 for insertion. The crimp end of the pin 14 is mated with the wire core 4 and is crimped and engaged by the crimp terminal 11.

[0033] In some embodiments, the connector end 1 has a plurality of connecting portions 13 on the contact surface near the external socket. The connecting portions 13 are sleeve-shaped, and the contacts of the pins 14 are disposed inside the connecting portions 13.

[0034] Specifically, the connector end 1 is provided with multiple connecting parts 13 for mating and insertion. The connecting parts 13 provide positioning and protection. Each connecting part 13 is sleeve-shaped, and each connecting part 13 contains a corresponding pin 14, enabling mating and insertion with external devices to achieve electrical connection when connecting the heavy-duty communication cable assembly. Furthermore, the independent connecting parts 13 achieve multi-point contact while also enhancing the vibration resistance of the heavy-duty communication cable assembly, preventing loosening due to vibration, and improving the stability of the insertion.

[0035] In some embodiments, the connecting portions 13 are arranged in two staggered rows.

[0036] Specifically, the connecting portions 13 are arranged in two staggered rows, improving space utilization and reducing connector size while maintaining a safe spacing, thus meeting the needs of portable devices. In some implementations, the two rows of connecting portions 13 on the connector end 1 are specifically arranged in three or four staggered rows. This asymmetrical layout serves as a natural foolproof design and also prevents mis-interlocking with other connectors of different specifications. It is understood that the specific numerical relationship of the connecting portions 13 can be determined according to the actual situation, and this application does not limit it here.

[0037] In this embodiment, the outer mold 2 of the heavy-duty communication cable assembly is distributed in three sections and has a bending section as a reinforcing rib for the overall structure. The central area has anti-slip texture 23 for easy insertion and removal. A connecting portion 13 is provided on the contact surface of the connector end 1, and a crimp terminal 11 is provided inside. The crimp terminal 11 is used to crimp the wire core 4 of the cable assembly with the crimp end of the pin 14. The contact end of the pin 14 extends into the connecting portion 13. The connecting portions 13 are staggered for signal isolation and can also enhance the overall tensile strength of the cable assembly.

[0038] Example 3: This embodiment represents a further structural optimization of the heavy-duty communication cable assembly of this utility model. Please refer to [link / reference]. Figure 1 and Figure 3 .

[0039] In some embodiments, both the connector end 1 and the inner mold 3 have small holes 5 on their longitudinal sidewalls for engaging with the outer mold 2.

[0040] Specifically, small holes 5 are provided on the connector end 1 and the inner mold 3. The small holes 5 are located on the longitudinal sidewall and can be covered by the outer mold 2. The setting of small holes 5 can increase the bonding strength of the outer mold 2, ensuring that the outer mold 2 can firmly secure the connection between the connector end 1 and the inner mold 3, and preventing the outer mold 2 and the inner mold 3 from peeling off during the pulling process.

[0041] In some embodiments, fasteners 12 for connection and fixation are symmetrically provided on the outer side of the connector end 1.

[0042] Specifically, fasteners 12 are provided on both sides of the connector end 1 to prevent detachment. The fasteners 12 can be of the snap-fit ​​type. When the connector end 1 is inserted into the interface of an external device, the barb of the elastic snap automatically engages with the corresponding slot of the device. When disassembling, pressing the vertical section of the snap deforms it, and the barb disengages from the slot, allowing it to be pulled out. Alternatively, the fasteners 12 can be of the threaded type, such as a rotating screw. The rotating screw passes through the mounting hole on the side of the connector end 1 and locks itself in place with the threaded post of the device.

[0043] In some embodiments, the tail 32 and the inner mold 3 are an integral structure.

[0044] Specifically, the design of the inner mold 3 and the mesh tail 32 set at the outlet position as an integrated structure can eliminate the connection gap between the inner mold 3 and the mesh tail 32, so that the stress can be continuously transferred from the inner mold 3 to the mesh tail 32, thereby enhancing the load-bearing capacity of the heavy-duty communication cable assembly. In addition, the seamless integrated structure can avoid the water leakage channels that may occur in the split design. Combined with the secondary wrapping of the outer mold 2, a double seal is formed, which can adapt to complex humid environments.

[0045] In some embodiments, the outer mold 2 is injection molded. Specifically, the outer mold 2 may be made of TPE material, but is not limited to, and the connector end 1 and the inner mold 3 are wrapped by a secondary injection molding process. During injection molding, the molten TPE material flows into the small hole 5 and forms a snap-fit ​​structure after cooling, which enhances the bonding strength between the outer mold 2 and the inner mold 3, so that the outer mold 2 does not require additional adhesives or mechanical fasteners 12 to achieve a reinforced bond.

[0046] In this embodiment, the heavy-duty communication cable assembly is secured by fasteners 12 symmetrically arranged on the outer side of the connector end 1. The fasteners 12 can be snap-fit ​​or threaded, engaging with the device's slot via hooks or locking with the device's threaded post via screws to prevent detachment. Small holes 5 are provided on the longitudinal sidewalls of both the connector end 1 and the inner mold 3. The outer mold 2 is injection molded; during injection, molten material flows into the small holes 5 and cools to form a snap-fit ​​structure, allowing the small holes 5 to be covered by the outer mold 2 to increase the bonding strength and prevent the outer mold 2 from separating from the inner mold 3 during pulling, thus improving load-bearing capacity. Furthermore, the tail 32 and the inner mold 3 are an integral structure, eliminating connection gaps and achieving continuous stress transmission to enhance load-bearing capacity. Combined with the secondary encapsulation of the outer mold 2, a double seal is formed to adapt to humid environments.
