Detailed Description
The terminology used in the description of the embodiments of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the application, as the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
At present, in some large electronic devices or communication systems, data and signals between a plurality of Printed Circuit Boards (PCBs) and a main board are connected through a backplane, and the connection between the plurality of PCBs and the backplane can be realized through a plurality of connectors, wherein the PCBs and the connectors are in a one-to-one relationship, that is, one PCB is connected to the backplane through one connector. However, due to factors such as the flatness of the crimping surface of the connector and the warping degree of the circuit board, after the connector and the circuit board are assembled in a crimping manner, a gap is easily formed between the crimping surface of the connector and the surface of the circuit board (the standard crimping gap generally accepted in the current production is less than or equal to 0.1mm), the gap has a very large influence on the crosstalk performance of signal transmission, for example, the crimping gap of about 0.05mm deteriorates by more than 5-8dB in the crosstalk amplitude of 25Ghz-35Ghz, and in addition, the existence of the crimping gap causes the signal transmission efficiency to be low.
With the improvement of the speed of the connector, for example, 56G + connectors in the prior art are usually shielded by adopting a conductive plastic structure around a signal pin of a connector crimping surface, the bottom of the conductive plastic structure is set to be a plane, and due to the comprehensive effect of various factors such as the flatness of the conductive plastic structure and the surface of a PCB, the fitting and gapless between all differential pairs of the connector are difficult to ensure in the actual assembly process. In order to ensure effective contact between the connector crimping surface and the circuit board, the conductive plastic structure is usually made of an elastic conductive plastic material, so that after the connector is crimped with the circuit board, the elastic conductive plastic structure can be compressed under the action of crimping force, thereby ensuring that the conductive plastic structure of the connector is bonded with the circuit board without a gap. However, the cost of the elastic conductive plastic material is high, which may increase the cost of the communication product.
Based on this, this application embodiment provides a connector, the cover is equipped with electrically conductive shielding part through signal pin all around, and electrically conductive shielding part deviates from being equipped with a plurality of electrically conductive pieces on the one side of connector body, can ensure to laminate the zero clearance between connector crimping face and the circuit board to reach the mesh that improves the signal and cross talk problem, can also solve the too high problem of material cost among the prior art simultaneously.
The specific structure of the connector will be described with reference to the accompanying drawings.

Specifically, conductive elements 40 may be added to the conductive shields 30 between different differential pairs of signal pins 20.
When the connector 100 is connected to a circuit board, the conductive member 40 can be tightly attached to the circuit board, so as to ensure that no gap is formed between the press-contact surface of the connector 100 and the circuit board, thereby achieving the purpose of improving the signal crosstalk problem. Meanwhile, the embodiment of the application can also solve the problems that the cost of the material is high and the service performance of the material is not mature in the prior art.
In addition, it should be noted that, since crosstalk between different signal pairs of the connector 100 is very sensitive, the shielding of the differential signal pairs is achieved by the conductive shield 30 between the different differential pairs. The conductive shield 30 can be continuously shielded at the crimping surface by attaching the metal of the surface layer of the PCB after crimping.

As shown in fig. 2 or fig. 3, a plurality of openings 301 may be formed on the conductive shielding element 30, an edge of each opening 301 has a distance from the signal pin 20, and the conductive element 40 is located between two adjacent openings 301. By forming the plurality of openings 301 on the conductive shielding member 30, the signal pins 20 are located in the openings 301, and the edge of the opening 301 and the signal pins 20 have a distance therebetween, a safe distance can be ensured between the conductive shielding member 30 and the signal pins 20, and the problem of signal short circuit between the conductive shielding member 30 and the signal pins 20 is avoided. Moreover, the conductive member 40 is disposed between two adjacent openings 301, so that the signal crosstalk problem can be better improved.
Referring to fig. 1, the connector body 10 may include: a support part 101 and a connection part 102 connected to the support part 101, wherein the signal pin 20 is located on the connection part 102, and the conductive shield 30 is disposed near the connection part 102.

By arranging the protrusion 303 on the main body 302 of the conductive shielding element 30, and using the protrusion 303 as the conductive element 40, it can be ensured that no gap is left between the conductive shielding element 30 and the circuit board after the connector 100 and the circuit board are connected by pressure, thereby achieving the purpose of reducing crosstalk at the pressure connection surface.
The protruding portion 303 has a certain height, and the surface of the protruding portion 303 contacting with the PCB is a compression joint stop surface, so that the conductive protruding portion 303 is completely attached to the surface of the PCB after compression joint, and the optimal crosstalk performance can be realized in performance.
As an alternative embodiment, the material of the protruding portion 303 may be conductive plastic (i.e., a plastic material with conductive property), or the material of the protruding portion 303 may be plastic, and a metal layer is disposed on an outer surface of the plastic, so as to form the protruding portion 303 with conductive function. The protrusion 303 may be a hard conductive plastic, a hard plastic with a metal layer on an outer surface, a soft (i.e., having a certain elasticity) conductive plastic, or a soft plastic with a metal layer on an outer surface, which is not limited in the embodiments of the present application.
It will be appreciated that the local hard bumps may also ensure contact, i.e., the conductive hard plastic or hard plastic metallization may also ensure that the protrusions 303 fully conform to the PCB surface, achieving optimal crosstalk performance in terms of performance.
Another possible implementation is: as shown in fig. 5, conductive member 40 is a compressible conductive medium disposed on conductive shield 30. The compressible conductive medium is arranged on the conductive shielding piece 30, and after the connector 100 is in compression joint with the circuit board, the compressible conductive medium is tightly attached to the circuit board, so that the conductive shielding piece 30 can be attached to the circuit board without a gap, and the purpose of reducing the crosstalk of a compression joint surface is achieved.
Wherein, as an alternative embodiment, the compressible conductive medium may be conductive adhesive.
Further, in the embodiment of the present application, the specific arrangement manner of the conductive member 40 on the conductive shielding member 30 includes, but is not limited to, the following possible implementation manners:
one possible implementation is: the conductive members 40 have a cylindrical structure or a conical structure, a plurality of cylindrical structures are located on a surface of the conductive shielding member 30 facing away from the connector body 10, and the cylindrical structures are located between two adjacent openings 301. For example, the conductive member 40 may have a cylindrical structure, a prismatic structure, a conical structure, or a strip-shaped structure. As shown in fig. 4, the conductive member 40 has a cylindrical structure. As shown in fig. 6, the conductive member 40 has a strip-shaped structure.
Another possible implementation is: as shown in fig. 7, the conductive member 40 has an L-shaped structure, a plurality of L-shaped structures are located on a surface of the conductive shielding member 30 facing away from the connector body 10, and the L-shaped structures are located between two adjacent openings 301.
Yet another possible implementation is: as shown in fig. 8, the conductive member 40 has a ring structure, and the opening 301 is located in the ring structure, so that the ring structure surrounds the signal pin 20.
It should be noted that the conductive shield 30 may be made of conductive plastic (i.e., a plastic material with conductive properties), or the conductive shield 30 may be made of plastic, and a metal layer is disposed on an outer surface of the plastic. The connector body 10 may be made of plastic material or the like.
In addition, in some embodiments, the material of the signal pin 20 may be copper alloy. The shielding leads 50 may also be made of copper alloy. Of course, in other embodiments, the signal pin 20 may be made of other metals. Shield leads 50 may be metal of other materials. The embodiments of the present application do not limit this, nor are they limited to the examples described above.
In a practical application scenario, in a straight high-speed crimp connector, the influence of the gap between the crimp stop surface of the conductive shielding element 30 and the PCB on the high-speed crosstalk is very large. As shown in fig. 9, L1 is a cross-talk curve diagram when the gap between the press-contact stop surface of the conductive shield 30 and the PCB is 0.1mm, L2 is a cross-talk curve diagram when the gap between the press-contact stop surface of the conductive shield 30 and the PCB is 0.05mm, and L3 is a cross-talk curve diagram when the conductive shield 30 is provided with the conductive member 40 and the conductive member 40 is attached to the PCB (the conductive member 40 is in good contact with the PCB), and it can be seen from the figure that, by providing the conductive member 40 on the conductive shield 30 and attaching the conductive member 40 to the PCB, the optimal cross-talk performance can be achieved.
As shown in fig. 9, in a high frequency band of 25-35Ghz relative to a crimp gap of 0.05mm, the crosstalk amplitude of the connector 100 provided in the embodiment of the present application is optimized by more than 8dB, and the crosstalk performance of the crimp surface is greatly optimized.

Specifically, conductive elements 40 may be added to the conductive shields 30 between different differential pairs of signal pins 20.
When the connector 100 is connected to a circuit board, the conductive member 40 can be tightly attached to the circuit board, so as to ensure no gap between the press-contact surface of the connector 100 and the circuit board, thereby achieving the purpose of improving the signal crosstalk problem. Meanwhile, the problems that the cost of the material is too high and the service performance of the material is not mature in the prior art can be solved.
In addition, it should be noted that, since crosstalk between different signal pairs of the connector 100 is very sensitive, the shielding of the differential signal pairs is achieved by the conductive shield 30 between the different differential pairs. The conductive shield 30 is crimped and then continuously shielded at the crimped surface by attaching the surface layer of the PCB.
In the embodiment of the present application, as shown in fig. 12, the connector 100 may further include: and a shielding pin 50, wherein the shielding pin 50 is electrically connected to the conductive shield 30, and an extending direction of the shielding pin 50 is identical to an extending direction of the signal pin 20.

As shown in fig. 11 or 12, a plurality of openings 301 may be formed on the conductive shielding element 30, and an edge of the opening 301 is spaced from the signal pin 20. Thus, a safe distance between the conductive shield 30 and the signal pin 20 can be ensured, and the problem of signal short circuit between the conductive shield 30 and the signal pin 20 can be avoided.
Referring to fig. 10, the connector body 10 may include: a support part 101 and a connection part 102 connected to the support part 101, wherein the signal pin 20 is located on the connection part 102, and the conductive shield 30 is disposed near the connection part 102.
Specifically, the support part 101 may include at least: first 1011 and second 1012 opposite sides, third 1013 and fourth (not shown) opposite sides, and a bottom 1014, the bottom 1014 being connected to the first 1011, second 1012, third 1013 and fourth sides.
In the present embodiment, one of the first side surface 1011, the second side surface 1012, the third side surface 1013, and the fourth side surface of the support 101 may be used as the crimping surface. For example, a fourth side surface (a surface opposite to the third side surface 1013) of the support 101 may be used as the pressure contact surface.
Further, in one possible implementation, as shown in fig. 10, the supporting portion 101 may be provided with a notch 1015, and the connecting portion 102 may be located on a plane parallel to the bottom surface 1014 in the notch 1015.
It should be noted that the conductive shield 30 may be made of conductive plastic, or the conductive shield 30 may be made of plastic, and a metal layer is disposed on an outer surface of the plastic. The connector body 10 may be made of plastic material or the like.
In addition, in some embodiments, the material of the signal pin 20 may be copper alloy. The shielding leads 50 may also be made of copper alloy. Of course, in other embodiments, the signal pin 20 may be made of other metals. Shield leads 50 may be metal of other materials. The embodiments of the present application do not limit this, nor are they limited to the examples described above.
In a practical application scenario, in the bent high-speed crimping connector, the influence of the gap between the crimping stop surface of the conductive shielding element 30 and the PCB on the high-speed crosstalk is very large. As shown in fig. 13, L1 is a cross-talk curve diagram when a gap between the press-contact stop surface of the conductive shield 30 and the PCB is 0.1mm, L2 is a cross-talk curve diagram when a gap between the press-contact stop surface of the conductive shield 30 and the PCB is 0.05mm, and L3 is a cross-talk curve diagram when the conductive shield 30 is provided with the conductive member 40 and the conductive member 40 is attached to the PCB (the conductive member 40 is in good contact with the PCB), and by providing the conductive member 40 on the conductive shield 30 and attaching the conductive member 40 to the PCB, an optimal cross-talk performance can be achieved.
As shown in fig. 13, in the high frequency band of 25-35Ghz, the crosstalk amplitude of the connector 100 provided in the embodiment of the present application is optimized by more than 10dB, and the crosstalk performance of the crimping surface is greatly optimized, relative to the crimping gap of 0.05-0.1 mm.
It should be noted that other technical features (such as a forming manner of the conductive element 40 and a specific arrangement manner of the conductive element 40 on the conductive shielding element 30) are the same as or similar to those of the first embodiment, and the same or similar technical effects can be achieved, and no repeated description is repeated in this embodiment.
