[0002] At present, with the continuous improvement of the automation and integration of mining equipment, the amount of data that needs to be transmitted between devices has increased significantly. The transmission rate of traditional connectors can no longer meet the usage requirements. At this stage, there is an urgent need for a connector that integrates high-speed transmission, waterproofing, power transmission and high-speed signal transmission, among which the focus is on improving the transmission rate of the signal transmission line.
[0003] In the existing technical solutions, the transmission circuits around the differential pairs have differential-to-common mode conversion and crosstalk effects on the differential pair signal transmission, making the differential pair transmission performance unable to meet the gigabit transmission rate requirements.

[0009] Furthermore, a bending limit structure is provided on the inner surface of one end of the socket shielding ring close to the plug insertion end. When the socket differential pair insulator contacts the bending limit structure, it indicates that the socket differential pair insulator is assembled in place.
[0010] Furthermore, a contact spring is provided on the outer surface of one end of the socket shielding ring close to the plug insertion end, so that the socket shielding ring can be in contact and conductive with the shielding structure of the adapter end after being plugged in.
[0011] Furthermore, the outer surface of the socket shielding ring is provided with positioning ribs in an annular direction for forming an interference fit with the socket insulator.
[0012] Furthermore, strip-shaped convex ribs are provided on the outer surface of the socket differential pair insulator along the axial direction, and the strip-shaped convex ribs form an interference fit with the socket shielding ring.
[0013] Furthermore, when shielding and isolating the surrounding power transmission lines, the shielding node is extended out of the PCB board pin or connected to the ground node of the PCB board connected to the socket through a wire for conduction.
[0014] Furthermore, when using a shielding ring to shield and isolate the surrounding power transmission lines, the socket shielding ring is provided with a limiting mechanism, and the limiting mechanism is a shielding ring stop plate, one end of which extends to the outside of the socket shielding ring and is arranged vertically downward. When the socket shielding ring is installed into the socket insulator, the shielding ring stop plate is tightly attached to the socket insulator.
[0015] Furthermore, when shielding and isolating the surrounding power transmission lines, the shielding node is connected to a conductive sheet, and the surrounding grounding nodes are conducted through the conductive sheet and the socket differential.
[0016] The present invention also provides a novel hybrid adapter connector, comprising a plug insulator, on which are provided at least two plug differential pair contacts constituting a plug differential pair, and a transmission node for transmitting power or signals, wherein at least two shielding nodes are provided between the plug differential pair contacts and adjacent transmission nodes, the two shielding nodes being symmetrically distributed about a perpendicular midline connecting the plug differential pair contacts, and the connection line of the two shielding nodes being parallel to a center line connecting the plug differential pair contacts;

[0018] The inner cavity of the plug shielding ring is provided with a plug differential pair insulator, and at least two plug differential pair contacts are provided in the plug differential pair insulator. A crimping sleeve is provided at the end of the plug shielding ring away from the plug end, and a cable is provided in the crimping sleeve. The tail of the plug shielding ring is connected to the shielding layer outside the cable to form a complete shielding loop.
[0019] Furthermore, the outer surface of the plug shielding ring close to the crimping sleeve or the inner surface of the crimping sleeve close to the plug shielding ring is provided with a contact protrusion, which forms an interference fit with the crimping sleeve through the contact protrusion and is connected to the plug shielding ring.

[0022] Furthermore, the upper surface of the inner cavity of the plug shielding ring is provided with a step I and an inner spring piece arranged obliquely. The inner spring piece and the step I correspond to the two positioning holes on the plug differential pair insulator, so as to limit the plug differential pair insulator.
[0023] The bottom of the outer surface of the plug shielding ring is provided with a step II and an outer spring piece arranged obliquely, which cooperates with the plug insulator to form a limit for the differential pair components.
[0024] The beneficial effects of the present invention are:
[0025] (1) The present invention provides a corresponding shielding ring on the outside of the differential of the plug and the socket, completely enclosing the differential pair inside the shielding ring, thereby shielding and isolating the influence of the surrounding transmission lines. The corresponding shielding ring in the socket and the plug can be conductive and conductive with the shielding layer of the cable connected to the differential pair to form a complete shielding loop;
[0026] (2) There are several ways to shield and isolate the surrounding power transmission lines with the shielding ring: connect the socket shielding ring to the ground node of the PCB board connected to the socket; connect the shielding ring to the ground nodes around the socket differential pair; there is no need to connect the shielding ring to the ground node, but it is necessary to ensure that the distance between the shielding ring and the PCB board connected to the socket is small after the socket is installed;
[0027] (3) There is no limit to the pinhole type of the contact outside the shielding ring. After adding a shielding ring to the differential pair for shielding and isolation, the transmission line outside the differential shielding ring can be symmetrically distributed or asymmetrically distributed with respect to the differential pair. When the differential external transmission line is asymmetrically distributed, the shielding ring mainly functions to reduce the influence of differential common mode conversion. When the differential external transmission line is symmetrically distributed, the shielding ring mainly functions to reduce the influence of crosstalk. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention.
[0039] Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.
[0040] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present application.
[0041] Differential (high-speed transmission requires differential signaling) is a key element in system design for controlling differential-mode to common-mode conversion. When differential signals are transmitted in the system and encounter power supply noise or interference from adjacent signals, the amplitude and phase changes of the positive and negative signals differ, converting the original ideal differential-mode signal into a certain common-mode signal.
[0042] That is, the transmission circuit around the differential pair has a differential-to-common mode conversion and crosstalk effect on the differential pair signal transmission, making the differential pair transmission performance unable to meet the gigabit transmission rate requirements. When the current size is determined, it is only necessary to control the current loop size to minimize the impact of power supply noise or interference from adjacent signals on the differential signal transmission performance. In order to eliminate the differential-to-common mode conversion and crosstalk effect brought by the differential external transmission line nodes on the differential pair transmission, such as Figure 1 As shown, the present invention places common ground shielding nodes between nodes 1 and 8, and between nodes 6 and 7 (where nodes 7 and 8 are differential pair signal nodes, and nodes 1 and 6 are transmission nodes adjacent to nodes 7 and 8). The two shielding nodes are symmetrically distributed about the perpendicular midline of the differential pair connection, ensuring that the connection line of the two shielding nodes is parallel to the center line of the differential pair. The common ground shielding node is a shielding metal component located between the differential pair and other contact components. Its function is to ensure that the distance and position of the two differential lines to the shielding component are completely symmetrical, so that the two differential lines have the same return path structure, thereby forming an equivalent current loop size. This reduces the impact of power supply noise or interference from adjacent signals on the differential signal transmission performance, ensuring high-speed transmission performance requirements.
[0043] The present invention further expands the shielding metal parts of the two shielding nodes into a shielding ring, which is relatively simple to implement in processing and assembly (if the two shielding nodes are connected and expanded into a surface, namely a shielding plate, its shape can be a semicircular semi-enclosed curved surface, etc., which can also isolate the differential pair from the surrounding transmission lines, but such semi-enclosed shielding plates are difficult to implement in processing and assembly). In this solution, the shielding ring can be circular, waist-shaped, rectangular, etc., and the material can be a conductive metal material or a material with a conductive coating. The shielding ring wraps the differential pair inside the shielding ring to achieve shielding isolation of the differential pair from other transmission lines outside the differential pair.
[0044] Specific as Figure 3 、 4As shown, the present invention provides a novel hybrid connector structure, including a socket, wherein the socket includes a socket differential pair, and the shielding members of two shielding nodes 11 of the socket are connected to form a socket shielding ring 4 surrounding the socket differential pair, and the socket shielding ring 4 is used to achieve shielding isolation of the differential pair from other transmission lines;
[0045] The socket also includes a socket differential pair contact 1 and a socket differential pair insulator 2. The two socket differential pair contacts 1 are sleeved in the socket differential pair insulator 2. The socket differential pair insulator 2 is sleeved in the inner cavity of the socket shielding ring 4. The socket shielding ring 4 is installed in the socket insulator.
[0046] The socket shielding ring 4 is provided with a positioning rib 10, a contact spring 19, and a bending limit structure 18. The positioning rib 10 is provided to form an interference fit when the socket shielding ring 4 is installed in the socket insulator, thereby reducing the shaking of the socket shielding ring 4 in the insulator;
[0047] The contact spring 19 is bent outward from the base, with the front end bent inward to guide the mating shield (e.g., plug shield) when mated. The socket shield 4 and plug shield 7 are in contact and conductive after mating. The spring structure provides a stable and reliable contact after assembly, allowing for multiple insertions and removals. There are no specific requirements for the spring's extension direction. In this solution, the spring extends with the front end toward the mating surface, and the same contact effect can be achieved with the root of the spring facing the mating surface. In addition to the spring, a convex contact structure can also be provided (similar to the contact between the plug shield and the crimp sleeve). However, when multiple insertions and removals are required, the spring structure offers advantages such as reliable connection and long service life.
[0048] The bending limit structure 18 bends the metal sheet at the front end of the socket shielding ring 4 toward the inside of the shielding ring. After the socket insulator and the socket shielding ring 4 are assembled, the front end of the socket differential pair insulator 2 fits into the bending part, realizing the limiting function of the socket differential pair insulator 2 and preventing over-assembly.
[0049] The socket differential pair components include a socket differential pair contact 1, a socket differential pair insulator 2, and a socket shielding ring 4. During assembly, the socket differential pair contact 1 is first forcefully inserted into the socket differential pair insulator 2 from the tail of the socket differential pair insulator, and a position limit is formed by the cooperation of the step of the socket differential pair contact 1 and the step hole of the socket differential pair insulator. The socket differential pair insulator 2 is then installed into the socket shielding ring 4. Strip ribs 17 are provided on the upper, lower, left, and right outer surfaces of the socket differential pair insulator 2. The outer strip ribs 17 of the socket differential pair insulator 2 form an interference fit with the socket shielding ring 4. The extension direction of the strip ribs 17 is consistent with the direction in which the socket differential pair insulator 2 is installed into the socket shielding ring 4. This is to prevent the socket differential pair insulator 2 from shaking up and down, left, and right in the socket shielding ring 4. A semi-cylindrical rib structure can also be provided on the outer edge plane of the front circumference of the socket differential pair insulator 2, but the shape is not limited to this, and any shape that can achieve an interference fit assembly effect is sufficient.
[0050] The socket differential pair insulator 2 and the socket shielding ring 4 at the socket end are flush, and the socket shielding ring 4 does not protrude from the socket differential pair insulator 2, but is higher than the socket differential pair contact 1. The first function is that the corresponding shielding ring can protect the internal differential pair contact during assembly, and the second function is to ensure that the shielding ring starts to contact before the contact during insertion, which means that the corresponding shielding ring guides first to ensure the insertion relationship of the contact;
[0051] The bending limiting structure bends the metal sheet at the front end of the socket shielding ring 4 toward the inside of the shielding ring. After the socket differential pair insulator 2 and the socket shielding ring 4 are assembled, the front end of the socket differential pair insulator 2 contacts the bending limiting structure of the socket shielding ring 4, indicating that the socket differential pair insulator 2 is assembled in place. The limiting function of the socket differential pair insulator 2 is realized through the bending limiting structure of the socket shielding ring 4, and finally the socket shielding ring 4 is installed into the socket insulator.
[0052] like Figure 5 、 6 The present invention also provides a novel hybrid adapter connector structure, including a plug, wherein the plug includes a plug differential pair, and the shielding members of two shielding nodes corresponding to the plug differential pair are connected to form a plug shielding ring 7 surrounding the plug differential pair, and the plug shielding ring 7 is used to achieve shielding isolation of the differential pair from other transmission lines;
[0053] The plug also includes a plug differential pair contact 3 and a plug differential pair insulator 5. The two plug differential pair contact members 3 are sleeved in the plug differential pair insulator 5. The plug differential pair insulator 5 is sleeved in the plug shielding ring 7. The plug shielding ring 7 is installed in the plug insulator. A crimping sleeve 8 is sleeved on the end of the plug shielding ring 7 away from the plug end. A cable 9 is arranged in the crimping sleeve 8. The tail of the plug shielding ring 7 is pressed against the shielding layer 12 on the outside of the cable 9 to form a complete shielding loop.
[0054] The outer surface of the plug shielding ring 7 near the crimping sleeve 8 and the inner surface of the plug shielding ring 7 are provided with contact bumps 6. The contact bumps 6 form an interference fit with the crimping sleeve 8 and are electrically connected to the plug shielding ring. The purpose is to form an interference fit with the crimping sleeve 8 after assembly, thereby achieving electrical connection between the plug shielding ring and the crimping sleeve, thereby forming a complete shielding circuit. Similarly, the contact bumps can also be provided inside the crimping sleeve 8 to achieve electrical connection between the plug shielding ring and the crimping sleeve 8 after assembly.
[0055] When assembling the plug differential pair components, first install the crimping sleeve 8 on the cable 9, and then complete the crimping or welding of the contacts and the cable. The next step is to force the plug differential pair contact 3 into the plug differential pair insulator 5 from the tail of the plug differential pair insulator 5, and form a limit by matching the step of the plug differential pair contact 3 with the step hole of the plug differential pair insulator 5. Then, install the plug differential pair insulator 5 into the plug shielding ring, and form an interference fit with the plug shielding ring through the outer strip ribs of the plug differential pair insulator 5 to prevent the plug differential pair insulator 5 from shaking inside the plug shielding ring. The next step is to install the crimping sleeve 8 on the outside of the plug shielding ring, and form an interference fit with the shielding ring through the contact convex points, and then press the tail of the plug shielding ring with the outer shielding layer of the cable to form a complete shielding loop. Finally, the plug differential pair shielding ring component is installed as a whole into the plug insulator.
[0056] The upper surface of the inner cavity of the plug shielding ring 7 is provided with a step I 702 and an inner spring piece 701 arranged at an angle. The inner spring piece 701 and the step I 702 correspond to the two positioning holes on the plug differential pair insulator 5, so as to limit the plug differential pair insulator 5; the bottom of the outer surface of the plug shielding ring 7 is provided with a step II 704 and an outer spring piece 703 arranged at an angle, which cooperate with the plug insulator to limit the differential pair components.
[0057] This patented product employs shielding rings on the outside of the differential pair plug and jack, completely encasing the differential pair within the rings and isolating them from the effects of surrounding transmission lines. Furthermore, the shielding rings in the plug and jack must be conductive and connected to the shielding layer of the cable connected to the differential pair, forming a complete shielding loop.
[0058] There are several ways to shield and isolate the surrounding power transmission lines using the shielding ring 4 of the shielding node or socket:
[0059] 1) Connect the shielding node or the socket shielding ring 4 to the ground node of the socket connected PCB board by extending the tail ends of the two ground pins at the shielding node or the socket shielding ring through the printed circuit board pins or connecting them to the ground node of the socket connected PCB board 14 through a wire;
[0060] 2) Connect the shielding node or shielding ring to the grounding nodes around the socket differential pair, as shown in the following example: Figure 8 As shown, a conductive sheet 16 extends from the shielding node or the socket shielding ring 4, and is connected to the grounding node 13 around the socket differential pair through the conductive sheet 16;
[0061] 3) There is no need to connect the shielding ring to the ground node. The socket shielding ring 4 is provided with a limiting mechanism. The limiting mechanism is a shielding ring stopper 15. One end of the shielding ring stopper 15 extends to the outside of the socket shielding ring and is set vertically downward. When the socket shielding ring 4 is installed in the socket insulator, the shielding ring stopper 15 is in close contact with the socket insulator. This limiting structure ensures the relative position of the shielding ring and the socket after the socket shielding ring is installed, achieving a smaller gap between the socket shielding ring and the PCB board. There is no specific limit on the smaller distance Δ, but the smaller Δ, the better the shielding effect of the shielding ring against external interference, and the smaller the impact of the transmission circuit outside the shielding ring on the differential pair inside the shielding ring, which can meet the higher transmission rate requirements of the differential pair.
[0062] When the socket shielding ring 4 and the plug shielding ring 7 are mated, the header mating surface is divided into two parts, completely enclosing the corresponding differential pair within the shielding ring. The outside of the shielding ring is the power supply and other transmission lines. The contact pinhole type outside the shielding ring is not limited. After the shielding ring is added to the differential pair for shielding and isolation, the transmission lines outside the shielding ring can be symmetrically or asymmetrically distributed with respect to the differential pair. Symmetrical distribution means that the power transmission lines outside the differential pair are symmetrical in position and type with respect to the differential pair, or that the signal transmission lines outside the differential pair are symmetrical in position with respect to the differential pair. Positional symmetry means that the transmission lines are symmetrically distributed about the midpoint of the differential pair connection. Type symmetry means that the polarity and potential of the symmetrically distributed transmission lines are the same. Asymmetry can lead to poor conversion capabilities between differential and common mode signals, which is not conducive to high-speed transmission. Adding a shielding ring to the differential pair when the distribution is asymmetrical is to eliminate the impact of differential and common mode conversion on the asymmetrically distributed transmission lines.
[0063] When distributed asymmetrically, the shielding ring has an isolation effect between different differential pairs of signals, reducing the crosstalk between different signal pairs (referring to the unwanted voltage noise interference generated by electromagnetic coupling on adjacent transmission lines when the signal propagates on the transmission line).
[0064] When differential transmission lines are asymmetrically distributed about the differential pair, differential-mode and common-mode signals can convert to each other (a major interference factor), resulting in differential-mode signal energy loss and affecting the differential pair transmission rate. The shielding ring is added to eliminate the effects of differential-to-common-mode conversion on the asymmetrically distributed transmission lines and improve the differential pair transmission rate.
[0065] When the differential external transmission lines are symmetrically distributed about the differential pairs, the differential pairs are opposite to the CAN signal circuit ( Figure 1The mutual inductance and mutual capacitance between the midpoints 3 and 4 and the two signal lines of the differential pair will cause noise on the line (the main interference factor), which is called crosstalk. In this case, the main function of adding a shielding ring is to eliminate the influence of crosstalk and improve the transmission rate of the differential pair.
[0066] The method of adding a shielding ring to the differential pair to increase the differential pair signal transmission rate can be used for connectors with different shapes (such as circular connectors, rectangular connectors or other special-shaped connectors).
[0067] When the headers are plugged in, multi-level guidance is adopted through the shell positioning keys and positioning grooves, insulators and shielding rings. Specifically, the multi-level guidance is to guide the header plugging process in multiple stages according to the different contact sequences of different parts when the headers are plugged in, so as to ensure that the header contacts are in a positive relationship when they start to be plugged in, and avoid problems such as failure to plug in, wrong plugging and oblique plugging.
[0068] The first level of guidance is for the socket insulator and the plug insulator. When the socket insulator and the plug insulator begin to contact, the insulators are guided to plug in with the corresponding matching shapes. The shapes are not limited as long as they can achieve a mutual matching effect.
[0069] The second level of guidance is achieved by the keyway of the plug housing and the key on the socket housing matching each other (the keyway can also be set on the socket housing and the key is located on the plug housing as required);
[0070] The third level of guidance is the plug-in guidance of the socket shielding ring and the plug shielding ring. As the header is plugged in, the plug shielding ring and the socket shielding ring begin to contact. The rounded chamfers on the outside of the socket shielding ring and the inside of the plug shielding ring guide the plugging of the shielding rings.
[0071] The fourth level of guidance is the contact (pin and socket) guidance: the ball head structure of the pin head and the chamfer of the socket hole guide the pin and socket to match.
[0072] The plugging process is guided by a multi-level structure, and the shell and insulator structure are designed to prevent errors in plugging and mis-plugging, while also ensuring that the contacts are aligned during plugging.
[0073] This product can be made of non-metallic or metallic shell material according to different usage scenarios, and you can also choose whether to add a sealing structure.
