[0002] Data cables can be used for power transmission and / or data transmission. A data cable includes an electrical connector, wire, and an insulating shell. The rear end of the electrical connector connects to the wire. The insulating shell covers the connection between the electrical connector and the wire, and a braided tail is provided at the rear end of the insulating shell to cover the front end of the wire for protection. The molding process of the insulating shell is as follows: first, an inner mold is formed to cover the connection between the electrical connector and the wire; then, an outer mold is formed to cover the inner mold and the front end of the wire. The end of the outer mold furthest from the electrical connector forms the braided tail.

[0003] However, the existing data cable has poor mesh tail structure strength. During multiple swing tests, the mesh tail bends frequently, and the rubber at the mesh tail position is prone to wear and breakage. This causes the copper wires wrapped at the bend of the mesh tail to easily fatigue and break, resulting in poor swing performance of the data cable. Utility Model Content

Therefore, the data cable of this application has better swing performance. Attached Figure Description

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] This utility model embodiment provides a data cable, such as Figures 1 to 4 As shown, the data cable includes an electrical connector 10, a wire 20, a first inner mold 30, a second inner mold 40, and an outer mold 50.

[0037] Electrical connector 10 can connect to external devices to transmit electrical energy or data.

[0038] The wire 20 is connected to the rear end of the electrical connector 10.

[0039] The first inner mold 30 includes an inner mold section 31 and a tail section 32. The inner mold section 31 covers the connection between the electrical connector 10 and the wire 20 and extends along the length of the wire 20 to cover the front end of the wire 20 to form the tail section 32. A first limiting structure 311 is formed on the inner mold section 31, and a second limiting structure 321 is formed at the front end of the tail section 32.

[0040] The second inner mold 40 covers a portion of the inner mold segment 31. A first limiting part 41 is formed on the second inner mold 40. The first limiting part 41 is embedded in the first limiting structure 311 to restrict the movement of the second inner mold 40 relative to the first inner mold 30.

[0041] The outer mold 50 covers the other areas of the second inner mold 40 and the inner mold segment 31. A second limiting part 51 is formed on the outer mold 50. The second limiting part 51 is embedded in the second limiting structure 321 to restrict the movement of the outer mold 50 relative to the first inner mold 30.

[0042] The data cable in this embodiment optimizes the outer layer protection of the data cable. The tail section 32 of the data cable is formed by the inner mold section 31 of the innermost first inner mold 30 extending along the length direction of the wire 20 and covering the front end of the wire 20. The second inner mold 40 covers a part of the inner mold section 31, and the outer mold 50 covers the other areas of the second inner mold 40 and the inner mold section 31. The relative movement between the first inner mold 30 and the second inner mold 40 is restricted by the first limiting part 41 on the second inner mold 40 being embedded in the first limiting structure 311 on the inner mold section 31. The second limiting part 51 on the mold 50 is embedded in the second limiting structure 321 on the tail section 32 to limit the relative movement between the outer mold 50 and the first inner mold 30, forming an interlock between the first inner mold 30, the second inner mold 40 and the outer mold 50, preventing the components of the data cable from separating during the swing test. The tail section 32 is formed by extending from the innermost first inner mold 30, which can increase the stress area of ​​the tail section 32 when frequently bent, and reduce the risk of bending wear and breakage at the tail section 32. Therefore, the data cable of this application has better swing performance.

[0043] refer to Figure 1 In an optional embodiment of this application, a plurality of strip holes 32a are provided on the tail section 32 to allow the wire 20 to pass through to the outside. The plurality of strip holes 32a are all extended along the circumference of the tail section 32 and are staggered on the tail section 32.

[0044] By creating strip-shaped holes 32a through the wire 20 to the outside in the tail section 32, the staggered distribution of multiple strip-shaped holes 32a allows the tail section 32 to undergo controllable local deformation when bent, absorbing bending energy and further reducing the risk of fatigue fracture of the tail section 32. The multiple strip-shaped holes 32a can be arranged in a regular, staggered pattern on the tail section 32, such as in an array, or they can be randomly staggered.

[0045] refer to Figure 2 , Figure 4 and Figure 5 In an optional embodiment of this application, a blocking portion 42 is formed at the front end of the second inner mold 40. The blocking portion 42 is exposed at the front end surface of the outer mold 50 and abuts against the front end surface of the outer mold 50.

[0046] By having the blocking part 42, which is integrally formed with the second inner mold 40, abut against the front end face of the outer mold 50, the outer mold 50 is further restricted from moving relative to the first inner mold 30 in the length direction, further preventing the outer mold 50 from separating from the second inner mold 40 during the swing test, thereby improving the structural strength of the data cable and further improving the swing performance of the data cable.

[0047] Optional, see reference Figure 4 and Figure 5 The blocking part 42 includes a limiting flange 421 surrounding the electrical connector 10, and the limiting flange 421 abuts against the front end face of the outer mold 50.

[0048] The limiting flange 421 surrounding the electrical connector 10 covers and protects the connection between the electrical connector 10 and the wire 20, and can evenly abut against the front end face of the outer mold 50 to form a radial constraint ring. During the swing test, the limiting flange 421 abuts against the front end face of the outer mold 50, restricting the outer mold 50 from generating radial swing, and further improving the swing performance of the data line.

[0049] In an optional embodiment of this application, reference is made to Figure 3 and Figure 4 The second inner mold 40 includes a transverse section 43, a first extension section 44, and a second extension section 45. The transverse section 43 surrounds and covers the front end of the inner mold section 31. The first extension section 44 and the second extension section 45 are respectively connected to the two ends of the transverse section 43 and extend along the length direction of the inner mold section 31 to cover the opposite sides of the inner mold section 31.

[0050] Specifically, the transverse segment 43 surrounds and covers the front end of the inner mold segment 31, providing additional physical protection for the connection between the electrical connector 10 and the wire 20, further preventing damage to the connection due to external forces (such as pulling) during use. Two extension segments begin from both ends of the transverse segment 43 and cover both sides of the inner mold segment 31 along its length. During the rocking test, the first extension segment 44 and the second extension segment 45 covering both sides of the inner mold segment 31 can limit excessive radial movement of the inner mold segment 31 along the wire 20, helping to maintain the relative position and shape of the inner mold segment 31 and reducing internal structural damage due to twisting. Furthermore, the first extension segment 44 and the second extension segment 45 covering both sides of the inner mold segment 31 respectively can increase the bonding area between the inner mold segment 31 and the second inner mold 40, improving the overall structural strength.

[0051] Further, see reference Figures 2 to 4The first limiting structure 311 includes at least one first limiting hole 311a and a communicating groove 311b corresponding to the first limiting hole 311a. The communicating groove 311b connects the first limiting hole 311a with the outer side of the inner mold section 31. The first limiting part 41 includes a first limiting protrusion 411 connected to the first extension section 44 or the second extension section 45 and corresponding to the first limiting hole 311a. The first limiting protrusion 411 is embedded in the first limiting hole 311a and the communicating groove 311b.

[0052] By designing at least one first limiting hole 311a and a corresponding connecting groove 311b, along with a cooperating first limiting protrusion 411, more precise positioning between the inner mold segment 31 and the second inner mold 40 can be achieved in the first limiting structure 311. The first limiting protrusion 411 is embedded in the first limiting hole 311a and the connecting groove 311b, forming an undercut structure between the inner mold segment 31 and the second inner mold 40. This undercut structure further ensures the positional stability of the inner mold segment 31 and the second inner mold 40 during long-term use or under external force and prevents relative slippage, resulting in higher structural strength for the data cable. The connecting groove 311b connects the first limiting hole 311a to the outside of the inner mold segment 31, facilitating the flow of injection molding material and forming the first limiting protrusion 411 and the corresponding extension, making processing more convenient.

[0053] Optionally, the first limiting hole 311a is provided through the outer side of the wire 20 and the inner mold section 31, and the first limiting protrusion 411 is embedded in the first limiting hole 311a and the connecting groove 311b and connected to the wire 20.

[0054] Since the first limiting hole 311a passes through the wire 20, the first limiting protrusion 411 of the second inner mold 40, after being formed, can not only be bonded to the first inner mold 30, but also glued to the wire 20, which enhances the connection strength between the wire 20, the first inner mold 30 and the second inner mold 40, reduces the possibility of relative movement between these components and improves the overall structural strength of the data cable.

[0055] refer to Figures 2 to 4 In an optional embodiment of this application, the first limiting structure 311 includes two first limiting holes 311a and corresponding connecting grooves 311b. The two first limiting holes 311a are distributed along the width direction of the inner mold section 31. The first extension section 44 and the second extension are both provided with first limiting protrusions 411. Each first limiting protrusion 411 is embedded in a first limiting hole 311a and a connecting groove 311b. The first limiting structure 311 also includes a second limiting hole 311c. In the length direction of the inner mold section 31, the second limiting hole 311c is located at the front end of the two first limiting holes 311a. The first limiting part 41 also includes a limiting post 412 embedded in the second limiting hole 311c.

[0056] Through the two first limiting holes 311a and the corresponding first limiting protrusions 411, as well as the additional second limiting holes 311c and limiting posts 412, a multi-point adhesive bond is formed between the first inner mold 30 and the second inner mold 40, increasing the adhesive bonding area between the first inner mold 30 and the second inner mold 40 and improving the structural strength.

[0057] refer to Figure 2 and Figure 4 In an optional embodiment of this application, the second limiting structure 321 includes an annular groove 321a surrounding the tail of the net, and the second limiting part 51 includes an annular protrusion 511 embedded in the annular groove 321a.

[0058] Specifically, the annular protrusion 511 of the outer mold 50 is embedded in the annular groove 321a at the front end of the tail section 32, and the front end face of the outer mold 50 abuts against the blocking part 42 of the second inner mold 40, so that the outer mold 50, the first inner mold 30 and the second inner mold 40 form an inverted structure, which increases the connection stability between the outer mold 50 and the first inner mold 30 and the second inner mold 40, reduces the possibility of separation between the components during the swing test, and further improves the overall swing performance of the data cable.

[0059] In an optional embodiment of this application, the first inner mold 30 is made of thermoplastic elastomer (TPE) with a hardness of 80A-90A. This provides the first inner mold 30 with good flexibility and elasticity, high abrasion resistance and tear resistance. The lower material hardness also increases the stress area of ​​the tail section 32 during frequent bending, resulting in a larger bending radius, thereby further reducing the risk of wear and breakage of the rubber at the tail section 32. Optionally, the hardness of the first inner mold 30 can be a value within the range of 80A-90A, such as 80A, 82A, 84A, 85A, 86A, 88A, or 90A. For example, the first inner mold 30 uses a thermoplastic elastomer with a hardness of 85A.

[0060] Furthermore, the hardness of both the second inner mold 40 and the outer mold 50 is greater than that of the first inner mold 30. This allows the second inner mold 40 and the outer mold 50 to effectively distribute the force on the data cable, reducing pressure on the first inner mold 30, providing stronger physical protection for the first inner mold 30, and extending the lifespan of the data cable. For example, the second inner mold 40 is made of thermoplastic elastomer with a hardness of 130A, and the outer mold 50 is made of thermoplastic elastomer with a hardness of 95A.

[0061] It should be noted that the wire 20 has various structures. Several embodiments are listed below for illustration.

[0062] refer to Figure 6In one embodiment, the cable 20 includes multiple transmission wires 21 and a first insulating layer 22. The multiple transmission wires 21 are connected to the rear end of the electrical connector 10, and the first insulating layer 22 covers the outer periphery of the multiple transmission wires 21. The multiple transmission wires 21 can transmit power or data. Each transmission wire 21 typically includes a conductive conductor and a conductive insulation layer covering the outer periphery of the conductive conductor. The first insulating layer 22 covering the outer periphery of the multiple transmission wires 21 can effectively isolate the transmission wires 21 from direct contact with the outside world, improving the electrical safety of the data cable.

[0063] Further reference Figure 7 In an optional embodiment, the wire 20 may further include a braided layer 23 and a second insulating layer 24. The braided layer 23 covers the outer periphery of the first insulating layer 22, and the second insulating layer 24 covers the outer periphery of the braided layer 23. The braided layer 23 covering the outer periphery of the first insulating layer 22 not only increases the mechanical strength of the wire 20, improving its tensile, deformation, sway, and elongation resistance, preventing external physical damage, but also improves abrasion resistance and extends the service life of the data cable. The second insulating layer 24 forms a protective barrier, effectively preventing oil, dust, and other possible contaminants from entering the wire 20, preventing damage caused by contaminants or water, such as corrosion and short circuits.

[0064] Optionally, the braided layer 23 can be made of secondary high-elastic nylon yarn and wrapped around the outer periphery of the first insulating layer 22. Nylon yarn has high tensile strength and abrasion resistance.

[0065] refer to Figure 8 In one embodiment, the cable 20 includes multiple transmission conductors 21 and a braided layer 23. The multiple transmission conductors 21 are connected to the rear end of the electrical connector 10, and the braided layer 23 covers the outer periphery of the multiple transmission conductors 21. The braiding covering the outer periphery of the multiple transmission conductors 21 increases the mechanical strength of the cable 20, improves its tensile strength, deformation resistance, sway resistance, and elongation resistance, prevents external physical damage, improves abrasion resistance, and extends the service life of the data cable. Optionally, the braided layer 23 can be made of secondary high-elastic nylon yarn and covers the outer periphery of the first insulating layer 22. Nylon yarn has high tensile strength and abrasion resistance.

[0066] The following combination Figures 3 to 5 The specific molding process of the data line in this application is described below:

[0067] First, a first inner mold 30 is formed. The inner mold section 31 of the first inner mold 30 covers the connection between the electrical connector 10 and the wire 20. At the same time, the tail section 32 is also formed. The inner mold section 31 has a first limiting hole 311a and a second limiting hole 311c of the first limiting structure 311. The tail section 32 has an annular groove 321a of the second limiting structure 321. Second, a second inner mold 40 is formed. The second inner mold 40 has a limiting protrusion 421 of the blocking part 42. The transverse section 43, the first extension section 44, and the second extension section 45 of the second inner mold 40 respectively cover the front end of the inner mold section 31 and the opposite sides of the inner mold section 31, and the first limiting protrusion 411 on the first extension section 44 and the second extension section is formed. The first limiting protrusion 411 is embedded in the corresponding first limiting hole 311a and connecting groove 311b. The second inner mold 40 fills the first limiting hole 311a and connecting groove 311b formed by the first inner mold 30. At this time, the second inner mold 40 and the first inner mold 30 form an undercut structure with high structural strength. Finally, the outer mold 50 is formed, which covers the other areas of the first inner mold 30 and the second inner mold 40. The annular protrusion 511 of the outer mold 50 is embedded in the annular groove 321a of the tail section 32 of the mesh, filling the annular groove 321a reserved after the tail section 32 of the mesh is formed, forming an undercut structure with the first inner mold 30, increasing the adhesive bonding area of ​​the first inner mold 30, the second inner mold 40 and the outer mold 50, and improving the structural strength.
