Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
Referring to fig. 2 to 4, an embodiment of the present invention provides a data line 20, where the data line 20 includes a signal transmission line 21, and the signal transmission line 21 includes: the data line comprises an insulator 211 and two conductor core wires 212, wherein two through holes 213 which are mutually isolated are arranged in the insulator, one conductor core wire 212 is arranged in each through hole 213, and the center distance of the cross sections of the two conductor core wires 212 is equal at any position in the length direction of the data line.
In the embodiment of the invention, the characteristic impedance between the two conductor core wires can be equal at any position in the length direction by setting the center distance of the cross sections of the two conductor core wires to be equal, so that the data passing through the output transmission line cannot generate too large fluctuation, the characteristic impedance of the data line can be equal at any position, and the beneficial effect of improving the signal transmission stability of the data line is achieved.
It should be noted that, after the insulator 211 and the two conductor core wires 212 are integrally disposed through the two through holes 213, the signal transmission line 21 can always maintain the consistency of the characteristic impedance in the data transmission process, thereby ensuring the stability of the data transmission. The matching of the two conductor core wires 212 and the two through holes 213 can keep the center distance of the cross section between the two conductor core wires 212 consistent all the time, thereby ensuring that the characteristic impedance of the two conductor core wires 212 to each position is the same.
It should be noted that the conductor core 212 in this embodiment is not a single strand, but a core formed by a plurality of wires in parallel. As shown in fig. 3 and 4, the present embodiment exemplarily describes a core wire composed of 7 wires. Of course, the number of the specific wires constituting the core wire is set according to actual needs, and the specific number is selected according to the loaded power.
In this embodiment, the conductor core wire 212 may be provided as a single wire or as a plurality of wires as needed. The specific number is set according to the actual application, for example, when the number of conductor cores 212 is 3, 4, 5, 6, etc. for data transmission, the number of conductor cores 212 is set to be corresponding, and the insulator 211 is also changed adaptively.
It should be noted that the signal transmission line 21 in the prior art generally adopts two methods, one is a coaxial line, and the other is a twisted pair line. The data line 20 uses a coaxial line for differential signal transmission, which is unacceptable from the cost of raw materials to the manufacturing process of the data line 20 manufacturers and mobile phone terminal factories. The twisted data line 20 has unstable differential impedance due to abnormal factors such as the twisted distance, variation of process parameters, and tightness of twisted pair. When the connector 10 is connected to the data line 20, the characteristic impedance at the connection position is completely different from the characteristic impedance of the data line 20, which affects the stability of the signal. In addition, the coaxial line and the twisted pair line cannot ensure that the characteristic impedance at each position is the same, and the signal transmission line 21 in this embodiment integrally sets the two wires to ensure that the characteristic impedance at each position is the same. The data line 20 in the prior art is shown in fig. 8.
It is noted that the calculation formula of the characteristic impedance is:
the capacitance is calculated as:
since the material and the twisted diameter of the core conductor are fixed at the beginning of the design of the data line, the relative area S and the relative permittivity ε of the signal transmission line 21 are fixed,
based on the above, after the signal transmission line 21 of the common data line 20 is manufactured into a product, the center distance of the cross section of the conductor twist diameter of the signal transmission line 21 is unstable, so that the characteristic impedance also jumps.
Optionally, in an embodiment of the present invention, the insulator 211 includes a first insulator body and a second insulator body, the two through holes are respectively disposed in the first insulator body and the second insulator body, and the first insulator body and the second insulator body are an integral structure.
In the embodiment of the present invention, the arrangement of the integral structure can make the insulator 211 and the two conductor core wires 212 more adaptive, ensure the indirect stability of the two conductor core wires 212, reduce the waste of the insulating material, and further improve the stability of the signal transmission line 21.
Further, the cross section of the insulator 211 may be provided in a "8" shaped structure.
In the embodiment of the present invention, the 8-shaped structure can make the insulator 211 and the two conductor cores 212 more suitable, and at the same time, can reduce the waste of the insulating material, and can further improve the stability of the signal transmission line 21 for transmitting signals. Of course, the cross section of the signal transmission line 21 may be provided in a rectangular structural configuration or other shaped configuration as required.
Alternatively, in an embodiment of the present invention, the first insulator sub-body and the second insulator sub-body are symmetrical with respect to a perpendicular bisector of the insulator 211.
In the embodiment of the present invention, after the first insulator body and the second insulator body are symmetrical with respect to the perpendicular bisector of the insulator 211, the two through holes 213 may be symmetrical with respect to the perpendicular bisector of the insulator 211, so that the distance between the centers of the cross sections of the two conductor core wires 212 installed in the two through holes 213 is equal at any position in the length direction of the data line, and it is ensured that the signal transmission line 21 can always maintain the consistency of characteristic impedance in the data transmission process, thereby ensuring the stability of the data transmission of the data line 20.
Optionally, in an embodiment of the present invention, a first distance is spaced between closest points of the two through holes 213, and a center distance of a cross section of the two conductor cores 212 is a second distance, where the second distance is greater than the first distance.
In the embodiment of the present invention, after the second distance is greater than the first distance, it is ensured that the two conductor cores 212 disposed in the two through holes 213 are disposed at an interval, and short-circuit linearity caused by the two conductor cores 212 crossing each other does not occur, thereby ensuring stability of the signal transmission line 21. Specifically, the first distance is D0, and the first distance is D1.
Optionally, in this embodiment of the present invention, the data line 20 further includes:
a charging line 22, the charging line 22 being disposed in parallel with the signal transmission line 21;
a ground wire 23, the ground wire 23 being disposed in parallel with the charging wire 22;
the inner shielding layer 24 wraps the signal transmission line 21, the charging wire 22 and the ground wire 23;
an outer shielding layer 25, wherein the outer shielding layer 25 wraps the inner shielding layer 24;
and the data line outer cover 27, the data line outer cover 27 is arranged on the outer side of the outer shielding layer 25 and wraps the outer shielding layer 25, and the data line outer cover 27 is made of an insulating material.
In the embodiment of the present invention, the above structure can make the data line 20 have better stability, and the arrangement of the plurality of shielding layers (the inner shielding layer 24 and the outer shielding layer 25) can make the signal transmission line 21 have stronger interference resistance. The data line 20 can be insulated and protected by the arrangement of the data line outer cover 27.
Alternatively, in the embodiment of the present invention, the inner shield layer 24 is an aluminum foil, and the outer shield layer 25 is a metal mesh formed by weaving or winding a metal wire.
In the embodiment of the present invention, after the inner shielding layer 24 is set as an aluminum foil and the outer shielding layer 25 is set as a metal mesh, the anti-interference capability of the signal transmission line 21 can be further enhanced. The metal mesh can isolate static electricity and avoid the interference of the static electricity.
Optionally, in the embodiment of the present invention, the data line 20 further includes a filling line 26, and the filling line 26 is disposed inside the inner shield layer 24 to fill a gap between the signal transmission line 21, the charging line 22, and the ground line 23.
In the embodiment of the present invention, the filling lines 26 are disposed to fill gaps between the connection lines, so as to ensure stability between the connection lines, and to make the appearance of the data lines 20 more round.
Referring to fig. 5 and 6, a schematic diagram of characteristic impedance variation at each position of the data line 20 in the prior art and a schematic diagram of characteristic impedance variation at each position of the data line 20 in the present invention are respectively shown. By contrast, the characteristic impedance of each position of the data line 20 fluctuates greatly in the prior art, and the difference between the maximum characteristic impedance and the minimum characteristic impedance is large, whereas the characteristic impedance of each position of the data line 20 fluctuates little and tends to be smooth in the present invention, which means that the data line 20 in the present invention can make the transmission of the signal transmission line 21 more stable.
Referring to fig. 9 to 13, an embodiment of the invention provides a connector 10 connected to a data line 20, where the data line 20 is the data line 20.
In the embodiment of the present invention, the connector 10 connected to the data line 20 is more stable and reliable in data transmission at the stage of the data line 20. The center distance of the cross section of the two conductor core wires is equal to any position in the length direction, so that the characteristic impedance between the two conductor core wires is equal to each other, the data passing through the output transmission line cannot fluctuate greatly, the characteristic impedance of the data line can be equal to each other at any position, and the signal transmission stability of the data line is improved.
Optionally, in the embodiment of the present invention, a bonding pad 12 is disposed on the connector 10, the bonding pad 12 includes a first bonding pad 121 and a second bonding pad 122, and the first bonding pad 121 and the second bonding pad 122 are respectively connected to the two conductor cores 212;
wherein a center distance of a cross section between the first pad 121 and the second pad 122 is equal to a center distance of a cross section between the two conductor cores 212.
In the embodiment of the present invention, after the center distance of the cross section between the first pad 121 and the second pad 122 is equal to the center distance of the cross section between the two conductor cores 212, the pad 12 and the signal transmission line 21 can be more adapted, so that the fluctuation of data during the connection between the pad 12 and the signal transmission line 21 is reduced, and the stability of data transmission at the connection position between the connector 10 and the data line 20 is improved.
Optionally, in the embodiment of the present invention, the cross-sectional areas of the first solder joint 121 and the second solder joint 122 are respectively the same as the cross-sectional areas of the two conductor cores 212;
wherein, the two through holes 213 are spaced apart by a first distance, and the first welding point 121 and the second welding point 122 are spaced apart by the first distance.
In the embodiment of the present invention, after the sectional areas of the first pad 121 and the second pad 122 are respectively the same as the sectional areas of the two conductor cores 212, and the interval between the closest points of the two through holes 213 is the same as the interval between the closest points of the first pad 121 and the second pad 122, the characteristics of the first pad 121 and the second pad 122 and the two conductor cores 212 can be closer to each other, so that the impedance characteristic between the first pad 121 and the second pad 122 is the same as the impedance characteristic between the two conductor cores 212, and further, the fluctuation of data during the connection between the pad 12 and the signal transmission line 21 is reduced, so as to improve the stability of data transmission at the connection between the connector 10 and the data line 20. After the first pad 121 and the second pad 122 are spaced apart by the first distance, i.e., D0, the distance between the first pad 121 and the second pad 122 can be made to be consistent with the spacing between the two through holes 213, so that the joint between the pad 12 and the signal transmission line 21 can have the same impedance characteristics as the data line itself at different positions, and the transmission fluctuation of data tends to be consistent during the connection between the pad 12 and the signal transmission line 21, thereby further improving the stability of data transmission at the connection between the connector 10 and the data line 20.
It should be noted that the calculation formula of the characteristic impedance is:
where L is a definite value, from which can be derived: the larger the capacitance C between the signal transmission lines 21, the smaller the characteristic impedance.
C is Capacitance (Capacitance), also referred to as "Capacitance", and refers to the charge storage at a given potential difference, denoted as C, and is given international units of farad (F). Generally, charges are forced to move in an electric field, and when a medium is present between conductors, the movement of the charges is blocked, so that the charges are accumulated on the conductors, resulting in the accumulated storage of the charges, and the amount of the stored charges is called as a capacitance.
The capacitance is calculated as:
wherein the meaning of each parameter is respectively as follows:
s is the electrode area in m 2; ε is the permittivity of the dielectric medium, with the unit of F/m; d is the inter-electrode distance in m; ε 0 is the vacuum permittivity, constant, with a value of 8.855 x 10-12F/m; the relative permittivity of ε r dielectric is given in F/m.
The material and thickness of the connector 10 are fixed parameters, and now, after the distance D (see fig. 10) of the signal transmission line 21 of the connector 10 is adjusted to be consistent with the data line 20, the relative area S is only adjusted to obtain the characteristic impedance consistent with the data line 20, as can be seen from fig. 4 and 5, by adjusting the relative area S of the signal pair of the connector 10, the required characteristic impedance is achieved to be consistent with the characteristic impedance of the data line 20. Therefore, the characteristic impedance can be smoothly transited without a bulge, and the signal integrity is ensured. As can be seen from comparison between fig. 8 and 12, the change of the characteristic impedance is more stable after the relative area S is adjusted to the preset value.
Optionally, in an embodiment of the present invention, the first solder joint 121 and the second solder joint 122 are respectively connected to the two conductor cores 212, and a center distance of a cross section of the first solder joint 121 and the second solder joint 122 is the same as a center distance of a cross section of the two conductor cores 212.
In the embodiment of the present invention, after the first pad 121 and the second pad 122 are respectively connected to the two conductor cores 212, when the relative area S between the first pad 121 and the second pad 122 is a preset value, the connector 10 may keep consistent with the characteristic impedance of the data line 20, and in combination with the signal transmission line 21 having the same characteristic impedance at each position, the characteristic impedance at each position may be kept stable all the time during the whole data transmission process, so that the data during the data transmission process is transmitted without loss, and the integrity and reliability of the data are ensured.

Further, the adapter has the first pad 121 and the second pad 122 described above fitted to the signal transmission line 21.
It should be noted that the bonding pad 12 of the present invention has more than the first bonding point 121 and the second bonding point 122, and the bonding pad 12 has other bonding pads for bonding wires, such as the ground wire 23, the bonding pad of the charging wire 22, and the like.
It is noted that, in the present invention, the center distance of the cross section between the two conductor cores 212 is D, and D is a preset value. The center distance of the cross section between the first pad 121 and the second pad 122 is also D to better bond the first pad 121 and the second pad 122 to the two conductor cores 212.
