[0029] The utility model is further described below in conjunction with specific embodiments and drawings.

[0030] See Figure 1-6 As shown, an anti-interference data cable includes a wire 1 and a connector 200 disposed at the end of the wire 1, wherein the connector 200 is electrically connected to the wire 1, so that the anti-interference data cable of the utility model can be used to transmit data and can also realize a charging function, which is the function of a conventional data cable.

[0031] Among them, the connector 200 includes a connector body 2 and an outer mold 3. The wire 11 extending from the end of the wire 1 is electrically connected to the connector body 2, and the outer mold 3 is integrally connected to the outer sheath 12 of the wire 1, so that the connector 200 forms a stable connection with the wire 1, ensuring the service life of the product.

[0032] In order to reduce signal interference and improve anti-interference ability, the following design is also made: the outside of the wire 11 is also sleeved with a magnetic ring 4 for anti-interference, and the outer mold 3 is also wrapped and fixed on the periphery of the magnetic ring 4, so that the magnetic ring 4 is fixed inside the connector 200. That is to say, the utility model integrates the magnetic ring 4 for anti-interference into the interior of the connector 200, which is different from the prior art solution of setting the magnetic ring assembly on the data line. Since the magnetic ring 4 is integrated into the interior of the connector 200, it also has the effect of reducing signal interference and improving anti-interference ability. There is no need to add a metal hoop to the data line to connect the upper and lower halves of the magnetic ring assembly as in the prior art, and there is no need to form a jacket on the outside of the data line to wrap the entire magnetic ring assembly and the metal hoop, thereby saving labor costs and jacket material costs, while also achieving the purpose of simplifying the structure, reducing parts, reducing costs, and improving assembly efficiency. In addition, the connector 200 uses its own required outer mold 3 to wrap and fix the outer periphery of the magnetic ring 4, thereby protecting the magnetic ring 4. Furthermore, since there is no magnetic ring assembly on the wire, the volume of the entire wire can be reduced, the weight is lighter, and it is convenient to curl and store. At the same time, the aesthetics of the entire anti-interference data line can be ensured, meeting the aesthetic requirements of users.

[0033] The magnetic ring 4 is an integrated structure with a simple structure and easy manufacturing. The magnetic ring 4 has a hole 41 that passes through the front and rear end surfaces. The end of the wire 11 passes through the hole 41 and extends out of the magnetic ring 4. It is also very easy to assemble. The width of the hole 41 is slightly larger than the sum of the diameters of all the wires 11, and the height of the hole 41 is slightly larger than the diameter of the wire 11, so that all the wires 11 can smoothly pass through the hole 41 to extend out of the magnetic ring 4. The height of the hole 41 is 0.1 to 0.2 mm larger than the diameter of the wire 11.

[0034] The connector 200 also includes a PCB board 5 disposed at the rear end of the connector body 2 and electrically connected to the terminal 22 in the connector body 2, a metal shell 6 fixedly wrapped around the rear end of the connector body 2 and the periphery of the PCB board 5, and the metal shell 6 is also wrapped and fixed around the periphery of the magnetic ring 4, so as to position the magnetic ring 4 and ensure the stability of the assembly structure of the magnetic ring 4, the outer mold 3 is injection molded around the periphery of the metal shell 6, and the wire 11 extending from the end of the wire 1 is welded and fixed to the PCB board 5 and is conductive. The metal shell 6 is added and fixedly wrapped around the rear end of the connector body 2 and the periphery of the PCB board and the magnetic ring 4, and the metal shell 6 is also wrapped around the periphery of the wire and is clamped and fixed to the end of the wire 1, so as to enhance the stability of the connection between the connector 200 and the wire 1, and further enhance the shielding effect.

[0035] Of course, the connector 200 may also not be provided with the PCB board 5, and the wires 11 and the terminals 22 may be fixed by welding to form an electrical connection.

[0036] The rear end of the PCB board 5 has an escape groove 51 and two push-back parts 52 located on both sides of the escape groove 51 and protruding outward. The rear end surface of the push-back part 52 contacts the front end surface of the magnetic ring 4, thereby positioning the magnetic ring 4 and preventing the magnetic ring 4 from being over-pressed, so that the magnetic ring 4 and the solder joints formed by the welding of the PCB board 5 and the wire 11 form a certain distance, thereby avoiding the risk of causing a short circuit. In addition, the end of the wire 11 is partially accommodated in the escape groove 51, thereby reducing the space required for the assembly of the wire 11, reserving a larger installation space for other components, or making the thickness of the entire connector 200 smaller.

[0037] In order to improve the overall structure of the connector 200 and make it more stable, the following design is added: the connector 200 also includes an inner mold 7, which also wraps the rear end of the connector body 2 and the periphery of the PCB board 5 and the magnetic ring 4, thereby ensuring that the inner mold 7, the rear end of the connector body 2, the PCB board 5 and the magnetic ring 4 form a stable whole, and can form a more stable assembly with the metal shell 6; the front end of the metal shell 6 is clamped and fixed to the rear end of the connector body 2, and the metal shell 6 is wrapped around the outer surface of the inner mold 7, which forms a more stable assembly structure, thereby extending the service life of the product.

[0038] The metal shell 6 is a stamped seamless structure, which has a stable structure, strong pressure resistance, better strength, better shielding effect, and stronger protection. The metal shell 6 includes a cylindrical body 61 and two convex hulls 62 formed on both sides of the cylindrical body 61 and protruding outward, and the front end of the convex hull 62 is flush with the front end of the cylindrical body 61 and connected; the rear end of the cylindrical body 61 is sleeved on the periphery of the end of the wire 1, and the front end of the cylindrical body 61 is sleeved into the rear end of the connector body 2, and is clamped and fixed by the front end of the convex hull 62 and the rear end of the connector body 2, and its assembly structure is extremely stable.

[0039] The structure of the connector body 2 is described in detail below.

[0040] The connector body 2 includes a plastic seat 21 , a plurality of terminals 22 , and a shielding shell 23 .

[0041] The front end of the plastic seat 21 has a slot 211 , and the rear end of the plastic seat 21 is provided with a terminal slot 212 penetrating the slot 211 .

[0042] The terminal 22 is inserted and fixed in the terminal groove 212, and the conductive portion 221 of the terminal 22 is exposed in the pair of slots 211. The rear end of the terminal 22 is provided with a receiving groove 222 and two pins 223 located on both sides of the receiving groove 222; the end of the PCB board 5 is inserted into the receiving groove 222 at the rear end of the terminal 22, and the pin 223 of the terminal 22 is welded and fixed to the pad 53 of the PCB board 5. Its assembly structure is extremely well positioned, and through the conductive connection of the double pins 223, its conductive performance is extremely ideal.

[0043] The shielding shell 23 is fixedly wrapped around the outer surface of the plastic seat 21 to achieve a tightening effect, and the shielding shell 23 also has a good shielding effect. The front end of the metal shell 6 is clamped and fixed with the rear end of the shielding shell 23 to form a stable connection.

[0044] The terminal 22 is in the shape of a flat plate, has high structural strength, will not deform unexpectedly, and has a very long service life.

[0045] The conductive portion 221 includes a first conductive arm 201 and a second conductive arm 202 which are symmetrically distributed. The first conductive arm 201 and the second conductive arm 202 have first conductive points 203 and second conductive points 204 which are relatively distributed on the inner sides of their front ends. The conductive portion 221 has an extremely ideal plug-in conductive performance.

[0046] A partition 213 is also provided in the terminal groove 212, and a relatively distributed first clamping point 205 and a second clamping point 206 are provided on the inner sides of the rear ends of the first conductive arm 201 and the second conductive arm 202. The first clamping point 205 and the second clamping point 206 are respectively clamped and positioned with the upper and lower surfaces of the partition 213 to form a primary clamping and positioning assembly, and a third clamping point 207 and a fourth clamping point 208 are respectively formed on the outer sides of the first conductive arm 201 and the second conductive arm 202. The third clamping point 207 and the fourth clamping point 208 are respectively clamped and positioned with the upper and lower inner walls of the terminal groove 212 to form a secondary clamping and positioning assembly, so that the terminal 22 can be stably installed in the plastic seat 21, thereby improving the quality of the connector body 2.

[0047] The upper and lower inner walls of the front end of the shielding shell 23 are both provided with a plurality of elastic arms 231 for increasing the plugging and unplugging force. The outer periphery of the front end of the plastic seat 21 is provided with a plurality of windows 214 penetrating the matching slots 211. The ends of the elastic arms 231 pass through the windows 214 and are exposed in the matching slots 211. The elastic arms 231 are pressed against the mating connector inserted into the matching slots 211 to enhance the plugging and unplugging force.

[0048] In summary, the utility model integrates the anti-interference magnetic ring 4 inside the connector 200, which is different from the prior art solution of setting the magnetic ring assembly on the data line. Since the magnetic ring 4 is integrated inside the connector 200, it also has the effect of reducing signal interference and improving anti-interference ability. There is no need to add a metal hoop to the data line to connect the upper and lower halves of the magnetic ring assembly as in the prior art, and there is no need to form a jacket on the outside of the data line to wrap the entire magnetic ring assembly and the metal hoop, thereby saving labor costs and jacket material costs, while also achieving the purpose of simplifying the structure, reducing parts, reducing costs, and improving assembly efficiency. In addition, the connector 200 uses its own required outer mold 3 to wrap and fix the outer periphery of the magnetic ring 4, thereby protecting the magnetic ring 4. Furthermore, since there is no magnetic ring assembly on the wire, the volume of the entire wire can be reduced, the weight is lighter, and it is convenient to curl and store. At the same time, the aesthetics of the entire anti-interference data line can be ensured, meeting the aesthetic requirements of users.
