[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] The data cable connectors in the prior art need to shield external signals to ensure stable data transmission. They are often equipped with built-in shielding covers. After shielding and isolation, the shell is processed again, or by secondary injection molding, or the processed shell is processed again by bonding or threading. The process is complicated and requires many equipments. At the same time, it is difficult to control the quality of the product during the production conversion process. That is, the data cable connectors in the prior art have the problem of inconvenient processing.

[0032] See also Figure 1 , Figure 2 , Figure 6 and Figure 7 In order to solve the above problems, the present invention proposes a data line connector 10. The data line connector 10 includes a base component 300, a shielding component 400, an interface component 200 and a circuit board 100. The base component 300 is provided with a through hole 313, and the through hole 313 is used for the wires such as the data line body 20 to pass through; the shielding component 400 includes an inner support member 410 and an outer cover 420, one end of the inner support member 410 is clamped with the base component 300, and the inner support member 410 has a limiting rib 412 protruding laterally at one end away from the base component 300, and the outer cover 420 is sleeved on the outer periphery of the inner support member 410, and the outer cover 420 is limited between the limiting rib 412 and the base component 300; the circuit board 100 is arranged in the inner support member 410 and connected to the wire passing through the through hole 313; the interface component 200 is connected to the circuit board 100 and extends from the inner support member 410.

[0033] The inner support member 410 in the shielding assembly 400 is connected to the base assembly 300 by snapping, which avoids the situation where the base assembly 300 and the inner support member 410 are connected by an external colloid. At the same time, the inner support member 410 has a limiting rib 412 protruding laterally at one end away from the base assembly 300. When the outer cover 420 is sleeved on the outer periphery of the inner support member 410 and the inner support member 410 is connected to the base assembly 300, the outer cover 420 is limited between the limiting rib 412 and the base assembly 300, which also avoids the situation where the outer cover 420 and the inner support member 410 are connected by an external colloid. Different from screw connection, magnetic connection and other methods, the snap connection is completed by the mechanical structure of the base assembly 300 and the shielding assembly 400 itself, which ensures the stability of the connection without adding additional parts such as screws and magnets, reduces the difficulty of production and processing, saves production costs, and optimizes the process steps during installation and assembly.

[0034] The base assembly 300 is also provided with a through hole 313, and the through hole 313 is for a wire to pass through. The circuit board 100 is arranged in the inner support 410, and the circuit board 100 is connected with the wire passing through the through hole 313 and the interface assembly 200, so as to realize the connection between the interface assembly 200 and the wire, and realize the functions of charging and / or data transmission of the interface assembly 200. The outer cover 420 is then sleeved on the outer periphery of the inner support 410 to provide multi-layer protection for the circuit board 100. The interface assembly 200 extends from the inner support 410, and the extended part is used to connect with other devices.

[0035] A rubber block 700 is also provided in the inner support member 410, and the circuit board 100 is arranged between the rubber blocks 700. The rubber block 700 has the function of waterproofing and shockproofing. When the data cable connector 10 is subjected to excessive external force or water penetrates into the shielding cover, the rubber block 700 can reduce the degree of external force on the circuit board 100 or prevent the water that penetrates from the outside from flowing onto the circuit board 100 and destroying the preset circuit on the circuit board 100.

[0036] See also Figure 2 , Figure 4 and Figure 5 In one embodiment, considering the small size of the data cable connector 10, if an overly complex clamping structure is provided on the base assembly 300, the difficulty of mold manufacturing will be greatly increased, which is not conducive to production. Therefore, the base assembly 300 is configured to include a base body 310 and a clamping ring 320, the clamping ring 320 is clamped with the base body 310, and the inner support member 410 is clamped with the clamping ring 320.

[0037] By arranging the collar 320 between the base body 310 and the shielding assembly 400, when the base body 310 is connected to the inner support 410, the collar 320 is clamped to the base body 310, and the inner support 410 is clamped to the collar 320. The collar 320 is used as a bridge between the base body 310 and the inner support 410, and the base body 310 and the inner support 410 are kept in a stable and tight connection through the clamping connection. And no other parts are needed to promote its connection. Only the inner support 410, the base body 310 and the collar 320 that meet the requirements are manufactured through a fixed mold to complete the installation. While ensuring the stable connection between the base body 310 and the inner support 410, the good shielding effect of the data cable connector 10, and the extended service life of the data cable connector 10, the difficulty of production, processing and installation of the data cable connector 10 is further reduced, and the manufacturing cost of the data cable connector 10 is saved.

[0038] See also Figure 6 , Figure 7 and Figure 8 Specifically, in one embodiment, the base body 310 includes a bearing portion 312 and a supporting portion 311 disposed on the bearing portion 312, a buckle platform 311a is disposed on the side of the supporting portion 311, and the clamping ring 320 includes a spring piece 321 and a clamping ring 322, an avoidance groove 322a is disposed in the middle of the clamping ring 322, the spring piece 321 is connected to the inner side of the avoidance groove 322a, and when the clamping ring 322 abuts against the bearing portion 312, the spring piece 321 is clamped with the buckle platform 311a. When the base body 310 and the collar 320 are installed and connected, the support portion 311 of the base body 310 passes through the avoidance groove 322a of the collar 322, and the spring piece 321 expands outward when it touches the buckle platform 311a. Finally, when the collar 322 slides to abut against the bearing portion 312, the spring piece 321 has slid past the buckle platform 311a and returns to its original state and no longer expands outward. At this time, the spring piece 321 abuts against the buckle platform 311a, and the position of the collar 320 and the base body 310 remains fixed.

[0039] If the connection surface between the buckle platform 311a and the support portion 311 is a right-angled surface, a greater force needs to be applied to enable the spring piece 321 to slide over the right-angled surface when installing and connecting the base body 310 and the retaining ring 320. Preferably, the connection surface between the top surface of the support portion 311 and the buckle platform 311a is a guide slope, and the connection surface between the spring piece 321 and the inner side of the avoidance groove 322a is a concave arc surface. During the installation of the base body 310 and the retaining ring 320, when the support portion 311 passes through the avoidance groove 322a, the arc surface of the spring piece 321 can slide in along the guide slope, thereby reducing the difficulty of installation.

[0040] Further, the spring piece 321 is provided with a clamping groove 321a, and the end of the inner support member 410 away from the limiting rib 412 is provided with a clamping portion 411, and the side of the clamping portion 411 is provided with a clamping protrusion 411a; the bearing portion 312 is provided with a receiving groove 312a, and when the inner support member 410 is connected to the base assembly 300, the clamping portion 411 extends into the receiving groove 312a, and the clamping protrusion 411a is clamped with the clamping groove 321a. When the inner support member 410 is installed and connected with the base assembly 300, the top surface of the clamping portion 411 abuts against the spring piece 321, and as the clamping portion 411 is squeezed deeper, the clamping protrusion 411a abuts against the inner side surface of the spring piece 321, and the spring piece 321 expands outward. When the engaging protrusion 411 a is pressed through the elastic sheet 321 , the engaging portion 411 enters the receiving groove 312 a . At this time, the engaging protrusion 411 a is engaged in the engaging groove 321 a .

[0041] If the connection surface between the clamping protrusion 411a and the clamping portion 411 is a right-angled surface, a greater force needs to be applied to make the right-angled surface slide over the elastic sheet 321 when installing and connecting the inner support member 410 and the clamping ring 320. Preferably, the connection surface between the top surface of the clamping portion 411 and the clamping protrusion 411a is set as a guiding inclined surface. During the installation and connection process of the inner support member 410 and the clamping ring 320, when the support portion 311 is pressed into the receiving groove 312a, the guiding inclined surface of the support portion 311 slides in close to the elastic sheet 321, reducing the difficulty of installation.

[0042] The collar 320 conveniently and effectively strengthens the connection between the base body 310 and the inner support member 410. However, if the data cable body 20 is not firmly connected to the circuit board 100 after being connected to the data cable connector 10, even if the base body 310 is not disconnected or falls off the inner support member 410, the data cable body 20 may be pulled out of the data cable connector 10 alone. In this embodiment, the collar 320, the support portion 311 and the clamping portion 411 also prevent the data cable body 20 from being pulled out. After the base assembly 300 and the inner support member 410 are connected, the support portion 311 and the clamping portion 411 form a connection channel 600 for the data cable body 20 to connect to the inner support member 410. When the data cable body 20 tends to be pulled out of the data cable connector 10, the support portion 311 on the outer periphery of the connection channel 600 tends to be compressed and shortened due to the influence of friction, and the spring piece 321 adjacent to the support portion 311 tends to be compressed and shortened due to the squeezing of the support portion 311. Furthermore, because in the length direction of the data cable connector 10, the spring piece 321 is connected to the inner side of the avoidance groove 322a on the clamping ring 320 in a concave arc, when the spring piece 321 is compressed and shortened, a component force is generated toward the connecting channel 600, and the support portion 311 and the clamping portion 411 are squeezed inward after being subjected to the component force, and the friction resistance between the data cable body 20 and the support portion 311 and the clamping portion 411 becomes larger, thereby reducing the tendency of the data cable body 20 to be pulled out of the data cable connector 10.

[0043] In addition to the inner support member 410, the shielding assembly 400 is also provided with an outer cover 420 sleeved on the outer side of the inner support member 410 to protect the components in the inner support member 410. After the base body 310, the collar 320 and the inner support member 410 are connected, the outer cover 420 can be restricted from moving in the direction of the base assembly 300. The limiting rib 412 protruding laterally from one end of the inner support member 410 away from the base assembly 300 can prevent the outer shell from moving in the direction away from the base assembly 300. During installation, the end of the inner support member 410 provided with the clamping portion 411 is first inserted into the outer cover 420. Since the end of the inner support member 410 away from the base assembly 300, i.e., the end facing away from the clamping portion 411, is provided with a protruding limiting rib 412, the end face of the inner support member 410 provided with the limiting rib 412 cannot pass through the outer shell, i.e., the movement of the outer cover 420 in the direction facing away from the base assembly 300 is restricted. However, the end face of the inner support member 410 provided with the limiting rib 412 is outside the outer cover 420, which is not conducive to processing the gap between this end face and the outer cover 420.

[0044] See also Figure 4 In view of this, in one embodiment, a limiting groove 421 is provided at one end of the inner wall of the outer cover 420 away from the base assembly 300, and when the outer cover 420 is sleeved on the inner support member 410, the limiting rib 412 abuts against the limiting groove 421 toward the bottom of the base assembly 300. The movement of the outer cover 420 in the direction away from the base assembly 300 is limited, and at the same time, the end face of the inner support member 410 provided with the limiting rib 412 is located inside the outer cover 420, so that the gap between this end face and the outer cover 420 can be processed.

[0045] The interface component 200 is used to connect with other devices. In order to achieve data transmission, the interface component 200 also needs to be connected to the circuit board 100. The circuit board 100 is arranged in the inner support member 410. In order to enable the interface component 200 to connect with other devices, the interface component 200 needs to extend out of the inner support member 410. There are many models of the interface component 200, including but not limited to USB (Universal Serial Bus) type A, USB type B, USB type C, HDMI (High Definition Multimedia Interface)-TYPE-A, HDMI-TYPE-B, HDMI-TYPE-C or HDMI-TYPE-D, etc.

[0046] See also Figure 4 and Figure 5In order to ensure the stability of the connection between the interface component 200 and other devices, it is necessary to fix the position of the interface component 200 without any deviation in any direction. To achieve the above purpose, in one embodiment, the interface component 200 is provided with a limiting boss 800 on the periphery of one side close to the circuit board 100. When the interface component 200 is extended from the inner support 410, the limiting boss 800 is limited in the inner support 410 and abuts against the end face of the inner support 410. At this time, it is only necessary to keep the limiting boss 800 in stable abutment with the end face of the inner support 410 to keep the position of the plug stable. There are many ways to keep the limiting boss in abutment with the end face of the inner support 410, such as screw connection, welding, bonding, etc. In this embodiment, in order to optimize the fixing method of the interface component 200, the limiting boss 800 is kept in stable abutment with the end face of the inner support 410 through the circuit board 100. When one end of the circuit board 100 is connected to the interface assembly 200, the other end abuts against the clamping portion 411 of the inner support member 410. The circuit board 100 abuts between the limiting boss 800 and the clamping portion 411 of the inner support member 410 to achieve stable abutment between the limiting boss 800 and the end face of the inner support member 410.

[0047] Please continue reading Figure 4 and Figure 5 In one embodiment, the data cable connector 10 is further provided with an annular baffle 500, which is arranged on the outer periphery of the interface component 200 and seals the limiting groove 421. The annular baffle 500 and the limiting groove 421 are interference fit, further limiting the movement of the inner support member 410 in the protective shell, and sealing the limiting groove 421 to prevent dust and other debris from entering the inner support member 410 through the connection gap between the inner support member 410 and the outer cover 420, thereby affecting the service life of the data cable connector 10. At the same time, the annular baffle 500 is arranged on the outer periphery of the interface component 200, further fixing the part of the interface component 200 in the limiting groove 421, and reducing the possibility of shaking of the interface component 200.

[0048] Preferably, in one embodiment, the inner support member 410 is connected to a ground wire, and the base assembly 300, the shielding assembly 400 and the interface assembly 200 are all made of metal materials. When leakage occurs, the base assembly 300, the shielding assembly 400 and the interface assembly 200 are connected as a whole and are all made of metal materials. After the inner support member 410 is connected to the ground wire, it can protect the user's safety and the safety of other devices that use the data cable connector 10 for charging and / or data transmission, and avoid electric shock, fire, and explosion.

[0049] The present invention also provides a data cable, the data cable includes a data cable body 20 and the data connector as described above, the data connector includes a circuit board 100, and the data cable is connected to the circuit board 100. The data cable body 20 includes a ground wire, and the ground wire is connected to the inner support member 410. The data cable provided by the present invention, because the data cable connector provided by the present invention is adopted, the data cable also has the advantages of convenient production, processing and installation, stable connection, good shielding effect, safe use and long service life.

[0050] The present invention also provides an electronic device, which includes a device body and a plug interface, wherein the plug interface matches the interface component of the data cable connector described above, and the electronic device can be charged and / or data transmitted by the data cable described above.
