Connector and electronic equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a connector and an electronic device.

Background

In an electronic device or among a plurality of electronic devices, in order to meet the requirements of power supply, data transmission, and the like, the electronic devices are usually equipped with a plurality of different types of connectors (interfaces). Taking a notebook computer as an example, the notebook computer may also be equipped with an audio/video interface (such as a display interface) to meet the transmission requirements of audio and video signals. In addition, the notebook computer is also equipped with a USB interface to realize signal transmission with external devices.

In practical applications, too many connectors may restrict the miniaturization design of electronic devices, and therefore, a normalized design of a plurality of connectors is required. However, current connectors can only meet a single communication standard specification. Therefore, a connector compatible with different communication standards is needed.

Disclosure of Invention

The application provides a connector and an electronic device capable of achieving different communication standard specifications.

In one aspect, the present application provides a connector for connecting two parts to be connected to electrically connect the two parts to be connected. The connector comprises a supporting body and a signal terminal assembly; the supporting body is an insulator, the signal terminal assembly is fixed on the supporting body, and the signal terminal assembly comprises a plurality of signal terminals arranged at intervals along a first direction. The signal terminal is used for transmitting electric signals and is electrically connected with the two parts to be connected. Wherein the plurality of signal terminals are arranged at two or more pitches. In the connector provided by the application, after the signal terminals are arranged at two or more pitches, two or more characteristic impedances can be realized so as to be compatible with two or more communication standard specifications. In addition, an additional protocol conversion chip is not needed, so that the normalization and miniaturization design of the connector are facilitated.

In a specific application, the pitch of the signal terminals may be greater than or equal to 0.2mm and less than or equal to 2mm. It can be understood that the pitch of the signal terminals is not limited to the above value range, and the pitch of the signal terminals can be designed reasonably according to actual requirements.

In some implementations, the connector can include at least two signal terminal assemblies. At least two signal terminal assemblies can be arranged in parallel, and the signal terminals in the two adjacent signal terminal assemblies are arranged in a staggered mode. To reduce cross-talk between adjacent two signal terminal assemblies.

In a specific application, the projection of the signal terminal in one signal terminal assembly to the signal terminal in the other signal terminal assembly in two adjacent signal terminal assemblies is not overlapped (or not overlapped) with the signal terminal in the other signal terminal assembly, so that the crosstalk between the two adjacent signal terminal assemblies can be effectively reduced.

Alternatively, when the projection of a signal terminal is located between two signal terminal assemblies, the projection of the signal terminal is the same or substantially the same as the distance between two adjacent signal terminals. Thereby effectively reducing crosstalk between two adjacent signal terminal assemblies.

Additionally, in some implementations, shield tabs can also be disposed between two adjacent signal terminal assemblies to inhibit cross-talk between adjacent signal terminals.

Wherein the distance between the shield blades and two adjacent signal terminal assemblies may be the same or substantially the same so that the shield blades provide good shielding and reference plane compliance.

In addition, the signal terminal assembly may also include a signal terminal for grounding. The signal terminals for grounding can be arranged between the signal terminals for transmitting high-speed signals, so that mutual capacitance and mutual inductance between the signal terminals for transmitting high-speed signals are effectively reduced, and mutual influence is avoided.

In some implementations, signal terminals for grounding can be connected to the shield blades so that crosstalk of the connector can be suppressed by the reference plane provided by the shield blades.

It is understood that, in the implementation, the signal terminal for grounding may be provided with one portion for connecting with the shielding plate, or may be provided with a plurality of portions for connecting with the shielding plate.

In addition, in practical use, the connector needs to satisfy a function of power transmission in addition to a function of signal transmission, and for this reason, a power supply terminal assembly may be included in the connector.

The power supply terminal assembly can be arranged on at least one side of the signal terminal assembly so as to reduce adverse effects such as interference and the like caused by the power supply terminal assembly on the signal terminal assembly as much as possible.

In particular implementations, the power terminal assemblies may include at least one power terminal and at least one ground terminal. The power supply terminal is used for transmitting electric energy, and the grounding terminal is used for providing a backflow path for the electric energy.

In addition, in order to meet the transmission requirement of high-power electric energy, the sizes of the power supply terminal and the ground terminal can be increased (for example, the widths of the power supply terminal and the ground terminal can be larger than that of the signal terminal) to improve the circulation capacity of the electric energy in the power supply terminal assembly, so that the power transmission requirement of higher power can be met.

In addition, in the actual use process, the power supply terminal and the ground terminal have larger current, so that in order to avoid the interference of the power supply terminal and the ground terminal on the signal terminal assembly or meet some high-voltage safety standard requirements, insulators such as plastic cement and the like can be arranged on the outer surfaces of the power supply terminal and the ground terminal. Alternatively, this may be accomplished by measures such as increasing the distance between the power terminal assembly and the signal terminal assembly.

The connector may also include a housing, as the case may be, for a particular application. The signal terminal assembly, the shield plate, and the power terminal assembly may be mounted in the housing through the supporting body. The shell not only can play a good role in protecting the supporting body, the signal terminal assembly and the power supply terminal assembly, but also can provide good electromagnetic shielding performance for the signal terminal assembly and the power supply terminal assembly, and can prevent adverse effects such as interference caused by external electromagnetic signals on the signal terminal assembly and the power supply terminal assembly.

In use, the connector may be fixedly mounted on the circuit board by the housing. The housing may include at least one solder tail extending outwardly therefrom, and the circuit board may have a pad or the like disposed thereon. After the welding feet of the shell are inserted into the through holes of the welding pads, the shell can be fixedly connected and electrically connected with the circuit board through a medium such as soldering tin.

There is also a need for connection between the shield plate and the circuit board. Therefore, in practical application, the solder legs of the shielding plate and the solder legs of the shell can be arranged in parallel, so that the solder legs of the shielding plate and the solder legs of the shell can be soldered with the same solder pad in the circuit board. In addition, the distance between the welding leg of the shielding sheet and the power supply terminal can be obviously increased on the premise of not additionally increasing the size of the connector, so that the requirement of safety regulations on the distance between power supply and ground can be favorably met.

In addition, in a particular application, when there is a high voltage current in the supply terminal assembly, the current may jump along the surface of the support body to the housing. In order to increase the path of the circuit at the time of the transition, a shielding body may be provided between the power supply terminal assembly and the case in the support body. The shielding body can be in a boss structure or a groove structure, or in other shapes, and the shape of the shielding body is not limited in the application.

In another aspect, the present application further provides an electronic device including the above connector. In a specific application, the electronic device may further include a substrate, and the connector may be disposed on the substrate and electrically connected to a microstrip line or other device in the substrate. Through the connector that this application embodiment provided, can be compatible two kinds or more than two kinds of communication standard specifications simultaneously to can effectively reduce the quantity that sets up of connector, thereby be convenient for realize electronic equipment's frivolousization and miniaturized design.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.

To facilitate understanding of the connector provided in the embodiments of the present application, the following first describes an application scenario thereof.

A connector, which may also be referred to as a plug, a socket, or an interface, is a component used to connect two components to be connected (e.g., active devices). In practical applications, the connector can realize the transmission of electric energy or electric signals between various active devices. The active device including the circuit board and the cable will be described as an example.

As shown in fig. 1, in one application scenario, a connector may be used to implement a board-to-board connection, i.e., two circuit boards may be connected by a connector. Specifically, the upper board surface of the circuit board 01 is mounted with a connector 011, and the conductive terminals in the connector 011 are electrically connected with the microstrip lines or other devices in the circuit board 01. The upper board surface of the circuit board 02 is installed with a connector 021, and a conductive terminal in the connector 021 is electrically connected with a microstrip line or other devices in the circuit board 02. When the connector 011 is mated with the connector 021, the terminals of the connector 011 are connected with the terminals of the connector 021, so that the circuit board 01 and the circuit board 02 can be electrically connected.

In another application scenario, as shown in fig. 2, the connector may be used to implement a board-to-wire connection, i.e., a connection between a circuit board and a cable. Specifically, the upper board surface of the circuit board 01 is mounted with a connector 011, and the conductive terminals in the connector 011 are electrically connected with the microstrip lines or other devices in the circuit board 01. One end of the connector 031 is connected to the cable 03, and the other end is used to connect to the connector 011. When the connector 011 is mated with the connector 031, the conductive terminals of the connector 011 are connected with the conductive terminals of the connector 031, so that the circuit board 01 and the cable 03 can be electrically connected.

In the conventional connector, only a single communication standard is provided, and two or more communication standard specifications cannot be compatible. The main reason is that the characteristic impedance of the connector varies with different communication standards. For example, a commonly used serial bus standard such as USB4.0 defines a connector with a characteristic impedance of about 85 ohms. Commonly used audio/video standards such as Displayport (DP) or High Definition Multimedia Interface (HDMI) define a connector with a characteristic impedance of about 100 ohms.

Therefore, the connector capable of being effectively compatible with two or more communication standard specifications is provided.

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and specific embodiments.

The terminology used in the following examples is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, such as "one or more", unless the context clearly indicates otherwise. It should also be understood that in the following embodiments of the present application, "at least one" means one, two, or more than two.

Reference throughout this specification to "one embodiment" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in another embodiment," and the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically noted.

As shown in fig. 3, in one embodiment provided herein, the connector 10 includes a support body 11 and signal terminal assemblies 12. The supporting body 11 is an insulator, and the signal terminal assembly 12 is fixed to the supporting body 11. The signal terminal assembly 12 includes a plurality of signal terminals 120 spaced apart in a first direction, wherein the plurality of signal terminals 120 are arranged at two or more pitches. Here, the pitch of the signal terminals 120 refers to a center-to-center distance between two adjacent signal terminals 120. Specifically, the center of the signal terminal 120 may be understood as a virtual center line of the signal terminal 120. For example, in the first direction, the signal terminals 120 generally have a certain width dimension, and the virtual center line is located at the middle of the width dimension and perpendicular to the first direction. The pitch of the signal terminals 120 can also be understood as a distance between the virtual center lines of two adjacent signal terminals 120. In the connector 10 according to the embodiment of the present application, two or more characteristic impedances can be realized by arranging the signal terminals 120 at two or more pitches so as to be compatible with two or more communication standards. For example, the connector 10 provided in the embodiment of the present application can be compatible with a serial bus standard (e.g., USB 4.0) and an audio/video standard (e.g., DP or HDMI) at the same time, and does not require an additional protocol conversion chip, thereby facilitating a normalized and miniaturized design of the connector 10.

The supporting body 11 mainly plays a role in position limitation and fixation of the signal terminals, so that the signal terminals are arranged according to preset positions and intervals and are firmly fixed on the supporting body 11. In specific implementation, the support 11 is an insulator, and may be made of a material with good insulation such as Polybutylene terephthalate (PBT) or Acrylonitrile Butadiene Styrene (ABS). The material, preparation process and shape of the support 11 are not limited in this application.

The signal terminals 120 are mainly used as a carrier for signal transmission, and can be made of materials with good electrical conductivity, such as copper, aluminum or alloy materials. In shape, the signal terminals 120 may be linear, curvilinear, or otherwise shaped. The present application is not limited to the material and shape of the signal terminals.

Characteristic impedance means that during signal transmission, where the signal edge arrives, a transient current I is generated between the signal terminal 120 and a reference plane (e.g., a power supply or a ground plane) due to the establishment of an electric field. If the output level of the signal is V, the signal terminal 120 is equivalent to a resistor with a resistance of V/I during the transmission of the signal. The equivalent resistance of the signal terminal 120 constitutes the characteristic impedance of the connector 10. The main factors determining the characteristic impedance of the connector 10 include: 1. the pitch of the signal terminals 120; 2. the distance between the signal terminal 120 and the reference plane; 3. the shape (e.g., width or thickness, etc.) of the signal terminals 120 themselves; 4. the dielectric constant of the support 11. In order to clearly explain the characteristic impedance, the output level of the signal is replaced with a symbol "V"; the above-mentioned instantaneous current is replaced by the symbol "I"; the resistance value is replaced by the symbol "V/I". Thus, the symbol "V" is not equivalent to a conventional voltage or level symbol and "I" is not equivalent to a conventional current symbol.

In practical applications, when the overall configuration of the connector 10 is determined, the size of the signal terminals 120, the dielectric constant of the supporting body 11 and the distance between the signal terminals 120 and the reference plane are fixed. Therefore, the embodiment of the present application controls the characteristic impedance of the connector 10 by adjusting the pitch of the signal terminals 120. It will be appreciated that the plurality of signal terminals 120 may be arranged in two or more pitches within the signal terminal assemblies 12 for a particular application.

For example, as shown in fig. 4, in one embodiment provided herein, the plurality of signal terminals 120 are arranged at two pitches. Specifically, there are 9 signal terminals 120 shown in fig. 4, and the pitches of 5 signal terminals 120 in the area A1 are all H1. In the area A2, the pitches of the 4 signal terminals 120 are all H2, and H1 is not equal to H2. By arranging the signal terminals 120 at two pitches, the connector 10 can have two different characteristic impedances, so that two communication standards can be compatible.

In particular applications, the value of H1 may be greater than or equal to 0.2mm, and less than or equal to 2mm. The value of H2 may be greater than or equal to 0.2mm and less than or equal to 2mm. In specific implementation, the values of H1 and H2 are not limited in this application.

In addition, in some embodiments, two sets of signal terminals 120 arranged at the same pitch may also be included in the signal terminal assemblies 12.

For example, as shown in fig. 5, in one embodiment provided by the present application, in the area A1, the pitches of the plurality of signal terminals 120 (4 are shown in the figure) are all H1. In the area A2, the pitches of the plurality of signal terminals 120 (17 are shown in the drawing) are each H2. In the area A3, the pitches of the plurality of signal terminals 120 (4 are shown in the drawing) are each H1.

In actual use, the pitches of the signal terminals 120 in the area A1 and the area A3 are the same, and therefore, the signal terminals 120 can be used as the signal terminals 120 of the same standard.

It will be appreciated that in other embodiments, three or more sets of signal terminals 120 may be included in the signal terminal assemblies 12, arranged at the same pitch. In addition, the signal terminals 120 in the signal terminal assemblies 12 may also be arranged at three or more pitches.

In addition, in order for the connector 10 to provide more signal transmission paths in a smaller space, two or more signal terminal assemblies 12 may be included in the connector 10.

As shown in FIG. 6, in one embodiment provided herein, two signal terminal assemblies, signal terminal assembly 12a and signal terminal assembly 12b, respectively, are included in connector 10. Specifically, a plurality of signal terminals are included in the signal terminal assembly 12a, and the plurality of signal terminals are arranged at intervals in the first direction. The signal terminal assembly 12b also includes a plurality of signal terminals, and the plurality of signal terminals are spaced apart along the first direction. The signal terminal assembly 12 and the signal terminal assembly 12 are arranged parallel to each other.

In a specific application, the signal terminal assembly 12a and the signal terminal assembly 12b can be designed to be symmetrical with respect to the center, so as to effectively reduce the number of components and parts used, and achieve the requirement of positive and negative insertion.

In addition, the signal terminals in signal terminal assembly 12a can be offset from the signal terminals in signal terminal assembly 12b to reduce cross-talk between signal terminal assembly 12a and signal terminal assembly 12b.

For example, the projection of the signal terminal of one of the signal terminal assemblies onto the other signal terminal assembly in two adjacent signal terminal assemblies does not overlap (or intersect) with the signal terminal 0 in the other signal terminal assembly 12. Specifically, as shown in fig. 7, the projection of the signal terminal 120a may be located between the signal terminal 120b and the signal terminal 121b.

Alternatively, in a particular application, when a signal terminal of one of the signal terminal assemblies is located between two signal terminals in the other signal terminal assembly, the projection of the signal terminal and the distance between two adjacent signal terminals may be the same or substantially the same. Specifically, the signal terminals in signal terminal assembly 12a and the signal terminals in signal terminal assembly 12b may be arranged in a center offset manner. For example, the projection of the signal terminal 120a may be located at a middle position of the signal terminal 120b and the signal terminal 121b. It is to be understood that the above description specifically describes only the signal terminal 120a, the signal terminal 120b and the signal terminal 121b as an example. For other signal terminals, the corresponding arrangement may also be performed according to the above-mentioned center-staggered manner, which is not described herein again.

In addition, after the signal terminals in the signal terminal assembly 12a and the signal terminal assembly 12b are arranged at two or more pitches, in order to ensure that the signal terminals in the signal terminal assembly 12a and the signal terminals in the signal terminal assembly 12b can be arranged in a way of shifting the centers, the adjustment pitch can be introduced in specific implementation.

As shown in fig. 8, in the signal terminal assembly 12a, the pitch of the signal terminals in the A1 region is H1; the pitch of the signal terminals in the A2 region is H2; the pitch of the signal terminals in the A3 region is H1; the pitch of the signal terminals in the A0 region is H3, where H3 is the adjustment pitch. In the signal terminal assembly 12B, the pitch of the signal terminals in the B1 region is H1; the pitch of the signal terminals in the B2 region is H2; the pitch of the signal terminals in the B3 region is H1; the pitch of the signal terminals in the B0 region is H3, where H3 is the adjustment pitch. And, H3=1/2 (H1 + H2).

For example, if H1 is 0.5mm; h2 is 0.3mm. When the arrangement is carried out, the relative position of the signal terminal in the A1 area is determined, the relative position of the signal terminal in the B1 area is determined, and the signal terminal in the A1 area is arranged in a way of being staggered with the center of the signal terminal in the B1 area. I.e., the projection of the signal terminal 120a is located at an intermediate position between the signal terminal 120b and the signal terminal 121b. In addition, since the relative positions of the signal terminals in the A2 and B2 regions have also been determined, the projection of the signal terminal 121a is located at an intermediate position between the signal terminal 121B and the signal terminal 122B. At this time, in order to ensure that the projection of the signal terminal 121b is located at the intermediate position between the signal terminal 120a and the signal terminal 121a, H3=1/2 (H1 + H2) =0.4mm needs to be ensured. It is understood that in other embodiments, more adjustment pitches H3 may be introduced. The position and the specific value of the adjusting pitch can be correspondingly set according to the actual situation.

In actual use, as shown in fig. 9 and 10, shield blades 13 may also be placed between the signal terminal assembly 12a and the signal terminal assembly 12b to prevent adverse effects such as cross talk from occurring between the signal terminal assembly 12a and the signal terminal assembly 12b. In particular implementations, the distance between the shield plate 13 and the signal terminal assembly 12a and the signal terminal assembly 12b may be the same or substantially the same to enable the shield plate 13 to provide better shielding performance and reference plane uniformity.

For example, as shown in FIG. 11, the shield plate 13 has a generally L-shaped plate-like configuration, with the horizontal segment of the shield plate 13 being spaced apart from the signal terminals 120a in the signal terminal assembly 12a by a distance h1 and from the signal terminals 120b in the signal terminal assembly 12b by a distance h2. The vertical segment of shield blade 13 is spaced a distance h3 from signal terminal 120a and a distance h4 from the signal terminals in signal terminal assembly 12. Wherein h1= h2= h3= h4. By designing the equal pitch, the distances from the signal terminals 120a and 120b to the shield plate 13 are substantially constant, and adverse effects such as crosstalk due to the non-uniform distances between the reference planes are avoided. It will be appreciated that in the embodiments described above, one signal terminal in signal terminal assembly 12a and one signal terminal in signal terminal assembly 12b are illustrated as examples. In practice, the shield blades 13 are spaced the same or approximately the same distance from all of the signal terminals in signal terminal assembly 12a and all of the signal terminals in signal terminal assembly 12b.

In addition, signal terminals for grounding may also be included in the signal terminal assemblies 12 in actual use. The signal terminals for grounding can be arranged between the signal terminals for transmitting high-speed signals, so that mutual capacitance and mutual inductance between the signal terminals for transmitting high-speed signals are effectively reduced, and mutual influence is avoided.

As shown in FIG. 12, signal terminal 121a is included in signal terminal assembly 12a for grounding and signal terminal 121b is included in signal terminal assembly 12b for grounding. The signal terminals 121a and 121b can be connected to the shield plate 13, so that the reference plane provided by the shield plate 13 can be utilized to suppress crosstalk of the connector 10.

In practical implementation, the tongue structure 131 and the tongue structure 132 may be disposed at corresponding positions of the shielding plate 13. The tongue structure 131 elastically abuts the signal terminal 121a, and the tongue structure 132 elastically abuts the signal terminal 121b. In addition, in order to ensure the connection effect, the tongue piece structure 131 and the signal terminal 121a may also be fixedly connected by using laser or other processes; correspondingly, the tongue structure 132 and the signal terminal 121b may also be fixedly connected by using a laser process or the like to prevent poor contact or separation.

Alternatively, as shown in fig. 13, the end portions of the signal terminals 121a and the end portions of the signal terminals 121b may be overlapped with the shield sheet 13.

It is understood that, in the implementation, each signal terminal for grounding may be connected to the shielding plate 13 in a multi-point connection manner. Alternatively, it is understood that a plurality of portions of the signal terminals for grounding may be connected to the shield plate 13 to effectively suppress crosstalk of the connector 10.

In the embodiments provided herein, the distance between the shield blades 13 and all of the signal terminals in signal terminal assembly 12a and all of the signal terminals in signal terminal assembly 12b is set to be the same or substantially the same. Furthermore, when the signal terminals for grounding are connected to the shield plate 13 in a multi-point connection manner, crosstalk generated when signals are transmitted through the connector 10 can be significantly reduced.

In order to make the technical effect more clear, the embodiment of the application also provides a comparative simulation diagram of crosstalk.

As shown in fig. 14, in the figure, the abscissa represents frequency (GHz), and the ordinate represents crosstalk value (dB); the solid line L1 represents the signal crosstalk curve of the connector 10 after the optimization of the shield plate 13; the dashed line L2 represents the signal-to-crosstalk curve of the connector 10 when the shield blades 13 are not optimized.

As is apparent from the figure, the crosstalk can be effectively reduced by more than 5dB after the shielding plates 13 are designed with equal spacing and connected with the signal terminals for grounding. In summary, in the embodiments provided in the present application, after the shielding plate 13 is optimized, the crosstalk data of the connector 10 can be significantly reduced, thereby being beneficial to ensure the transmission quality of signals. The Crosstalk may include Integrated Far-end Crosstalk (IFEXT) and Integrated Near-end Crosstalk (IFEXT), among others.

In addition, in practical use, the connector 10 needs to satisfy functions of power transmission in addition to the functions of signal transmission, and for this reason, a power supply terminal assembly may be included in the connector 10.

As shown in FIG. 15, in one embodiment provided herein, connector 10 includes a signal terminal assembly 12a, a signal terminal assembly 12b, and a power terminal assembly 14. The power terminal assembly 14 may include four power terminals and four ground terminals therein. Wherein the power supply terminal 141a is provided in pair with the ground terminal 142 a; the power supply terminal 141b and the ground terminal 142b are provided in a pair; the power supply terminal 141c and the ground terminal 142c are provided in a pair; the power supply terminal 141d is provided in pair with the ground terminal 142d. I.e., the power supply terminal is used to transmit power and the ground terminal is used to provide a return path for the power.

In the embodiments provided herein, to reduce the interference caused by the power terminal assembly 14 with the signal terminal assembly 12a and the signal terminal assembly 12b, the power and ground terminals in the power terminal assembly 14 can be located on both sides of the signal terminal assembly. Specifically, the power supply terminal 141a and the ground terminal 142a are located on the left side of the signal terminal assembly 12 a; the power supply terminal 141c and the ground terminal 142c are located to the right of the signal terminal assembly 12 a. The power supply terminal 141b and the ground terminal 142b are located on the left side of the signal terminal assembly 12 b; the power and ground terminals 141d and 142d are located to the right of the signal terminal assembly 12b.

It will be appreciated that in other embodiments, when a single signal terminal assembly (e.g., signal terminal assembly 12 a) is included in connector 10, a single power terminal and a single ground terminal may be included in power terminal assembly 14, and the power and ground terminals may be located on the same side of signal terminal assembly 12a or may be distributed on both sides of signal terminal assembly 12 a. The number of the power supply terminals and the ground terminals is not limited in the present application.

In addition, in the specific implementation, the sizes of the power supply terminal and the ground terminal in the power supply terminal assembly 14 may be increased to improve the circulation capability of the power in the power supply terminal assembly 14, so as to meet the power transmission requirement of higher power.

For example, as shown in fig. 16, the power supply terminal 141c and the signal terminal 120a are taken as an example. The width of the power supply terminal 141c is significantly greater than the width of the signal terminal 120a.

It will be appreciated that in other embodiments, the thickness of the power and ground terminals in the power terminal assembly 14 may be increased or made of a material having a lower resistance.

Alternatively, the contact resistance of the power supply terminal assembly 14 may be reduced by a reasonable positive pressure design to enhance the current carrying capability of the power. Specifically, as shown in fig. 16, the power supply terminal 141c is taken as an example. The left end of the power supply terminal may be provided in a spring arm structure, and when the power supply terminal 141c is overlapped with another power supply terminal, the tight overlapping between the two power supply terminals may be maintained by an elastic force (i.e., a positive pressure) provided by the spring arm structure. Therefore, in practical applications, in order to reduce the contact resistance between the two connected power supply terminals, the elastic force provided by the elastic arm structure can be lifted by a proper amount to lift the positive pressure.

In addition, because the power supply terminal and the ground terminal may have a large current during actual use, in order to avoid the interference of the power supply terminal and the ground terminal to the signal terminal assembly 12 or to meet some high-voltage safety specification requirements, insulators such as plastic may be disposed on the outer surfaces of the power supply terminal and the ground terminal. Alternatively, this can be accomplished by measures such as increasing the distance between the power terminal assembly 14 and the signal terminal assembly 12a and the signal terminal assembly 12b.

In addition, as shown in fig. 17, the connector 10 may further include a housing 15 in a specific application. Specifically, the housing 15 may be a substantially rectangular frame-like structure, and the signal terminal assembly 12a, the signal terminal assembly 12b, the shield plate 13, and the power supply terminal assembly 14 may be mounted inside the housing 15 through the supporting body 11. The housing 15 can not only protect the supporting body 11, the signal terminal assembly 12a, the signal terminal assembly 12b and the power supply terminal assembly 14 well, but also provide good electromagnetic shielding performance for the signal terminal assembly 12a, the signal terminal assembly 12b and the power supply terminal assembly 14, and prevent adverse effects such as interference caused by external electromagnetic signals on the signal terminal assembly 12a, the signal terminal assembly 12b and the power supply terminal assembly 14. During the preparation, the shell 15 may be made of a material with a good conductivity, such as stainless steel or copper alloy, wherein the material, shape and preparation process of the shell 15 are not limited in the present application.

In addition, as shown in fig. 18, the connector 10 can be fixedly mounted on the circuit board 20 by the housing 15 at the time of application. The housing 15 may include at least one solder leg 151 extending outwardly therefrom, and the circuit board 20 may be provided with a pad 21 and the like. After the solder tails 151 of the housing 15 are inserted into the through holes of the pads 21, the housing 15 and the circuit board 20 can be fixedly and electrically connected by a medium such as solder. The circuit board 20 may be a printed circuit board or a flexible circuit board, and the application does not limit the specific type of the circuit board 20.

In addition, as shown in fig. 19, in practical application, since the shielding plate (not shown) needs to be connected to the circuit board 20 through the solder 130, and the power supply terminal (e.g., the power supply terminal 142 a) needs to be connected to the circuit board 20. The conventional shielding plate is usually soldered by a surface-mounting process to the solder pads 130 of the shielding plate and the solder pads 21 on the circuit board 20. However, in a limited space, the distance between the solder leg 130 of the shield piece and the power supply terminal 142a is made too small. When the voltage in power supply terminal 142a is large, current designs cannot meet the distance requirements of safety regulations for the power supply (e.g., power supply terminal 142 a) and ground (e.g., solder tail 130).

For this reason, as shown in fig. 20, in an embodiment provided by the present application, the solder tails 130 of the shielding plate (not shown in the drawings) and the solder tails 151 of the housing 15 may be juxtaposed, so that the solder tails 130 of the shielding plate and the solder tails 151 of the housing 15 can be soldered to the same pads 21 in the circuit board, so as to significantly increase the distance between the solder tails 130 of the shielding plate and the power supply terminals 142a without increasing the size of the connector 10. It is to be understood that the power supply terminal 142a mentioned above is merely an exemplary illustration, and in practical applications, the power supply terminal may be any one of the power supply terminal assemblies.

In addition, in a specific application, when a high voltage current is present in the power supply terminal, the current may transition to the case along the surface of the supporting body 11. To increase the path of the circuit at the transition, a shield can be provided in the support body 11.

Specifically, as shown in fig. 21, the power supply terminal 141a is taken as an example. When the shielding body is not provided in the supporting body 11, the length of the transition path between the power supply terminal 141a and the case 15 is D.

As shown in fig. 22, when the shield body 111 of the boss structure is disposed in the supporting body 11, the transition path between the power supply terminal 141a and the case 15 is D +2h. Where h is the height of the shielding body 111, the transition path between the power supply terminal 141a and the housing 15 can be effectively extended by the shielding body 111. So that a large current in the power supply terminal 141a can be prevented from jumping into the case 15.

It is understood that in other embodiments, the shielding body 111 may also have a groove structure. In addition, in a specific application, the shielding body 111 may also include a plurality of boss structures or groove structures. Or, the shape, size and arrangement position of the shielding body 111 can be reasonably set according to actual requirements, which is not limited in this application.

In summary, as shown in fig. 23, the connector 10 provided in the embodiment of the present application can simultaneously meet the transmission requirements of two different communication standard specifications, i.e., audio/video signals and data signals. Alternatively, it is understood that two or more characteristic impedances may be realized by arranging the signal terminals in the connector 10 at two or more pitches to be compatible with two or more communication standard specifications, and no additional protocol conversion chip is required. In addition, the power supply terminal assembly (not shown in the figure) can meet the required power supply requirement, thereby being beneficial to realizing the normalized and miniaturized design of the connector 10.

In addition, as shown in fig. 24, in actual use, the connectors are generally used in pairs. For example, when connection between the circuit board 01 and the circuit board 02 needs to be established, the connector 10a may be provided on the circuit board 01 and electrically connected to the circuit board 01. The connector 10b may be provided on the circuit board 02 and electrically connected to the circuit board 02. When the connector 10a is connected to the connector 10b, the circuit board 10 and the circuit board 20 are connected to each other.

The specific structure of the connector 10a can be similarly designed with reference to the structure of the connector shown in fig. 17.

The specific structural composition of the connector 10b can be referred to fig. 25. Specifically, the connector 10b may include a support 11a and a support 11b. The signal terminal assembly 12a may be secured in the support body 11a and the signal terminal assembly 12b may be secured in the support body 11b. The shield sheet 13 may be disposed between the support 11a and the support 11b. The signal terminal assembly 12a, the signal terminal assembly 12b, and the shield plate 13 may be fixedly mounted in the housing 15 by the supporting body 11a and the supporting body 11b.

It is understood that in other embodiments, the specific structure, the number of the components and the connection relationship between the components of the connector 10b may be reasonably set according to actual requirements, and the application is not limited thereto.

In addition, in specific applications, the definitions of the signal terminals in the signal terminal assemblies can be reasonably set according to actual requirements.

For example, the signal terminal assembly and power terminal assembly 14 shown in FIG. 26 are taken as an example. In the figure, two signal terminal assemblies are included, signal terminal assembly 12a and signal terminal assembly 12b, respectively. Signal terminal assembly 12a includes 23 signal terminals 120a therein. Also included in signal terminal assembly 12b are 23 signal terminals 120b. The power supply terminal assembly 14 includes a power supply terminal 141a, a power supply terminal 141b, a ground terminal 142a, and a ground terminal 142b on the left side. And the power supply terminal assembly 14 further includes a power supply terminal 141c, a power supply terminal 141d, a ground terminal 142c, and a ground terminal 142d on the right side.

The flexibility in defining each of the signal terminal assembly 12a, signal terminal assembly 12b and power terminal assembly 14 can be adjusted according to actual needs.

For example, as shown in fig. 27, the embodiment of the present application provides a typical signal layout.

In this figure, reference numerals 1 to 27 denote terminals arranged in order from left to right in the lower row of fig. 26, respectively. Reference numerals 28 to 54 denote terminals arranged in order from right to left in the upper row in fig. 26, respectively.

It is understood that, in practical applications, each terminal may not be defined by the signal arrangement shown in the drawings, and the present application is not limited thereto.

Fig. 28 is a graph of impedance simulation data of the connector provided in the embodiment of the present application. In the figure, the abscissa represents time (or corresponds to different positions of the connector; in particular, when a signal is transmitted in the connector, the signal is transmitted to different positions of the connector over time). The ordinate represents the impedance value (Ω); curve M1 represents the impedance of the signal terminal for transmitting the DP signal in signal terminal assembly 12 a; curve M2 represents the impedance of the signal terminal for transmitting the DP signal in signal terminal assembly 12 b; a curve M3 represents the impedance of the signal terminal for transmitting the USB signal in the signal terminal assembly 12 a; the curve M4 represents the impedance of the signal terminal for transmitting USB signals in the signal terminal assembly 12b.

The detailed simulation structure is summarized in the following table 1 (note: since DP2.0 has no detailed specification index of crosstalk, refer to the specification index of USB 4.0).

TABLE 1

In Table 1, IRL is Integrated Rrturn Loss (INTEGRATED Rrturn Loss). IFEXT is Integrated Far-end Crosstalk (Integrated Far-end Crosstalk). IFEXT is Integrated Near-end Crosstalk (Integrated Near-end Crosstalk).

It can be seen from the above simulation data that, with the connector provided in the embodiment of the present application, after the signal terminals are arranged at two pitches, two characteristic impedances can be realized, so that the connector can be compatible with two different communication standard specifications (such as the above USB4.0 standard and the DP2.0 standard), and has a stable transmission effect.

It will be appreciated that in practice, the connector may be used in many different types of electronic devices.

For example, as shown in fig. 29, in the electronic device 30 provided in the present application, the connector 10 is included. In a specific application, the electronic device 30 may further include a substrate (not shown), and the connector 10 may be disposed on the substrate and electrically connected to a microstrip line or other device in the substrate. Wherein, the substrate can be a printed circuit board or a flexible circuit board. In addition, the devices disposed on the substrate may include a processor, a power module, or a filter, among many different types of devices. Through the connector 10 provided by the embodiment of the application, two or more than two communication standard specifications can be compatible at the same time, so that the number of the connectors can be effectively reduced, and the light, thin and miniaturized design of the electronic equipment is facilitated.

In addition, in practical applications, the electronic device may be a notebook computer, a television box or a display, and the application does not limit the specific application scenario of the connector 10.
