Detailed Description
The terminology used in the description of the embodiments section 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 present application.
In the present embodiment, a connector and an electronic device using the connector are described, and the following briefly describes concepts related to the embodiments:
a connector: generally, an electrical connector, i.e., a device for connecting two active devices, is used to transmit current or signals between the two active devices after the connector is connected to the two active devices.
Crosstalk: mainly refers to the coupling phenomenon between two signal lines. Due to the close spatial distance of the signal lines, inductive and capacitive coupling occurs between the two, thereby interfering with each other. As the transmission rate of signals transmitted by the connector increases, certain crosstalk may occur between signal lines of the connector, which may affect the integrity of signal transmission. Reducing and reducing signal crosstalk and loss in connectors is one of the problems that connector designs face.
A shielding module: the shielding module refers to a grounding unit in a basic sheet-shaped unit module, wherein the connector is arranged in a direction parallel to the mounting substrate, the unit comprises a plurality of metal leads, and the grounding unit has a common ground network attribute.
Differential signaling: a numerical value is used to indicate the difference between two physical quantities. Differential signals, also known as differential mode signals, are referred to as common mode signals. Differential signals are a pair of symmetrical signals of equal magnitude and opposite polarity that are used to transmit useful signals. The signal can play a strong anti-interference role in external interference during differential transmission.
The connector assembly provided by the embodiment of the application can be applied to the scenes of high-speed signal interconnection among single boards, between a single board and a backplane, between modules, between a chip and a backplane, or between a backplane and a daughter card, and the connector assembly in the embodiment can support 56G to 112Gbps PAM4 high-speed signal transmission. One Pulse in Pulse Amplitude Modulation (PAM for short) and PAM4(4Pulse Amplitude Modulation (PAM 4 for short) has four states (namely four possible voltage values), and a PAM4 signal is used as a hot gate signal transmission technology for high-speed signal interconnection in a next-generation data center. In the prior art, currently, a typical high-speed signal transmission generally adopts an NRZ mode, and the speed generally can reach 25Gbps, wherein NRZ refers to Non-Return-to-Zero (NRZ), and a digital signal can be directly transmitted by a baseband. The baseband transmission is an electrical pulse for directly transmitting digital signals in a line, which is the simplest transmission mode, and the local area network of the short-distance communication adopts the baseband transmission at present.
For the application scenario that needs to support high-speed signal transmission (such as 56G to 112Gbps transmission speed) under development, PAM4 mode transmission is generally adopted. However, the PAM4 mode transmission has a higher requirement for signal integrity when transmitting through a high-speed connector, and it is generally required to perform omni-directional shielding between adjacent signals of the connector to improve the integrity of the transmitted signals. Therefore, the connector assembly provided by the embodiment of the application can solve the problem of signal crosstalk between adjacent signals in the contact area of the connector during high-speed signal transmission, so as to improve the integrity of the transmission signal. In the following, the application scenario of high-speed signal interconnection between the backplane and the daughter card is taken as an example in the present embodiment, and the connector assembly of the present application is further described.

When two shielding parts 131 set up the both sides at terminal group relatively, and enclose when establishing in the outside of signal terminal 12 jointly, the cavity structure of the shielding part 131 of difference has formed the first chamber 111 that holds of shielding part 13 jointly in every shielding part 13, wrap up the outside or circumference of signal terminal 12 through first chamber 111 that holds, can surround two signal terminals 12 in every terminal group in shielding part 13 respectively like this, thereby realize all-round shielding and protection to signal terminal 12 circumference part, avoid mutual interference between the signal, and then solve the signal crosstalk problem of connector, in order to promote the integrality of signal during the high-speed transmission.
Further, referring to fig. 1 and 4, in order to make the arrangement of the shielding element 13 more flexible, the different shielding parts 131 in the shielding element 13 are arranged at intervals, so that the shielding parts 131 have a smaller volume, the arrangement and use of the shielding element 13 or the shielding parts 131 are more flexible, and the adjustment of the shielding element 13 or the shielding parts 131 is facilitated.
It should be noted that, when the different shielding parts 131 in the shielding parts 13 are arranged at intervals, in order not to affect the shielding and protecting effects of the shielding parts 131 on the signal terminals 12 opposite to the shielding parts 131, in the embodiment, by adjusting the interval distance between the different shielding parts 131 in each shielding part 13, at least the shielding part 13 is required to wrap the circumference of the two signal terminals 12 in the terminal group.
Further, as shown with reference to fig. 1 and 4, each of the shields 13 includes:

Further, as shown in fig. 1 and 4, the two shielding portions 131 are symmetrically disposed.

Further, referring to fig. 6 to 13, the connector assembly of the present embodiment further includes:
a second connector 2 that is pluggable onto the first connector 1, wherein the second connector 2 includes: a second base 21 and at least one electrical contact module 22 attached to the second base 21;
the electrical contact module 22 includes: the end pins of the signal contacts 221 are correspondingly inserted into the signal terminals 12, and the second base 21 is provided with a second slot 211 for inserting the shielding element 13.
On the one hand, after the first connector 1 and the second connector 2 are plugged, the end pin of the signal contact element 221 and the signal terminal 12 are correspondingly plugged and conducted, so that current or signal transmission is realized; on the other hand, the second slot 211 on the second base 21 makes the connection between the first connector 1 and the second connector 2 more secure, and shortens the distance between the end pin of the signal contact 221 and the end of the signal terminal 12, thereby enhancing the connection between the corresponding pins in the connectors.
Specifically, as shown in fig. 10 to 13, the second connector 2, as another connector that is plugged with the first connector 1, is used as a female connector in the connector assembly of the embodiment of the present application, and is mounted on the clip and connected to the device such as the clip, and the terminal set in the conductor terminal in the embodiment is conducted to the pair of signal contacts 221 in the second connector 2, so that the first connector 1 and the second connector 2 are electrically connected, thereby achieving high interconnection between the backplane and the clip, and further achieving electrical connection and signal transmission between the two devices.
It should be noted that the number of the electrical contact modules 22 in the second connector 2 may be one or more, and is opposite to and corresponds to the number of the conductor terminals in the first connector 1. In particular, the number of electrical contact modules 22 may vary depending on the number and size of conductor terminals that are desired.
In order to complete the transmission of a plurality of signals, the corresponding signal contact 221 may be correspondingly plural. The signal contacts 221 may be differential signal contacts 221, in which case a plurality of signal contacts 221 may be arranged in pairs, and each pair of signal contacts 221 may be used to transmit a differential signal pair. When the first connector 1 and the second connector 2 are plugged, the signal contacts 221 are plugged with the signal terminals 12 correspondingly and are conducted, so that the number of pairs of signal contacts 221 is equal to the number of terminal groups, that is, the number of signal contacts 221 is equal to the number of signal terminals 12, and the positions of the signal contacts 221 are in one-to-one correspondence.
Referring to fig. 6 to 8, in the present embodiment, a third accommodating cavity 23 is provided in the second base 21, the electrical contact module 22 is located in the third accommodating cavity 23, and the third accommodating cavity 23 is configured to protect internal components (such as the electrical contact module 22) in the second connector 2.
In order to achieve the insulating property of the surface of the connector assembly, in the present embodiment, the second base 21 may be a housing made of an insulating material, wherein the insulating material may be plastic or resin, for example.
Further, referring to fig. 6 to 13, in order to facilitate the insertion of the first connector 1 and the second connector 2, the shape of the second slot 211 and the shape of the shielding member 13 are matched with each other, so that the insertion of the first connector 1 and the second connector 2 is easier, the insertion manner of the first connector 1 and the second connector 2 is easier to distinguish, and the accuracy of the insertion is improved to a certain extent. Meanwhile, when the first connector 1 and the second connector 2 are plugged, the signal terminals 12 in the terminal group and the signal contacts 221 in the pair of signal contacts 221 corresponding thereto are plugged into each other and conducted. Since the shape of the second slot 211 matches the shape of the shield 13, and the position of the second slot 211 is opposite to the position of the shield 13, after the first connector 1 and the second connector 2 are plugged, the shield 13 and the end of the signal terminal 12 opposite to the shield 13 pass through the second slot 211 through the second base 21, wherein the end of the signal terminal 12 and the end pin of the signal contact 221 are plugged into each other and conducted, at the same time, the end pin of the signal contact 221 plugged into the signal terminal 12 enters the shield 13, that is, the shield 13 wraps the signal terminal 12 and at least part of the end pin of the signal contact 221, thereby providing an isolation barrier between signals for the plugging area of the first connector 1 and the second connector 2 (i.e., the plugging area of the signal terminal 12 and the signal contact 221), and avoiding mutual interference between signals, therefore, the problem of signal crosstalk of the plugging area (namely the contact area) of the connector assembly is solved, and the integrity of signals in high-speed transmission is improved.
Further, as shown in fig. 8 and 9, the electrical contact module 22 further includes:
the ground contact 222, and the signal contact 221 are arranged in parallel, and an end pin of the ground contact 222 is in contact with the shield 13.
Thus, when the end pin of the grounding contact 222 is in contact conduction with the shield 13, on the one hand, the grounding of the connector assembly is realized to realize the shielding and protection of the signal terminal 12; on the other hand, the grounding contact 222 and the shielding piece 13 are in the same network, so that the distribution of the grounding network is increased, the return path of return current or signals is increased, and the crosstalk between the signals is reduced.
Specifically, as shown in fig. 8 and 9, at least a signal contact 221 and a ground contact 222 are included in each electrical contact module 22. The signal contact 221 is used for signal transmission, and the ground contact 222 is used for ground isolation and shielding. The signal contacts 221 and the ground contacts 222 may have various structures and types for performing functions such as signal transmission or ground shielding. For example, the signal contact 221 and the ground contact 222 are both sheet-shaped or plate-shaped conductive connection structures, or the signal contact 221 may be a signal trace and the ground contact 222 may be a ground line. That is, in the present embodiment, the signal contact 221 and the ground contact 222 include, but are not limited to, a conductive connection structure.
In the present embodiment, as shown in fig. 8 and 9, each electrical contact module 22 may also have a plurality of ground contacts 222, and the number of the ground contacts 222 may match the number of the signal contacts 221. For example, when the signal contacts 221 are differential signal contacts 221, a pair of signal contacts 221 for transmitting a differential signal pair may be mated with one ground contact 222, and the ground contact 222 may be located between the two signal contacts 221 or on the sides of the two signal contacts 221.
Referring to fig. 8 and 9, the signal contacts 221 and the ground contacts 222 in each electrical contact module 22 may be arranged side by side in sequence. For example, the electrical contact module 22 may have a plate-like or sheet-like structure as a whole, and the signal contacts 221 and the ground contacts 222 on the electrical contact module 22 may be arranged side by side in the direction of the plate surface.
In order to avoid a short between the ground contact 222 and the signal contact 221, the ground contact 222 and the signal contact 221 need to be relatively insulated from each other. Specifically, as shown in fig. 8 and 9, the signal contact 221 and the ground contact 222 may be arranged at an interval so that the signal contact 221 and the ground contact 222 have a certain interval therebetween, or the first insulating member 224 may be arranged between the signal contact 221 and the ground contact 222 so that the signal contact 221 and the ground contact 222 are arranged at an interval, thereby achieving the insulating isolation between the signal contact 221 and the ground contact 222. Specifically, the first insulating member 224 may be sleeved on an end portion of the plate-shaped structure provided with the ground contact 222, and the first insulating member 224 may allow a certain distance between the signal contact 221 and the ground contact 222.
In a possible implementation manner, the first contact connection portion 24 is disposed on the shield 13, and the shield 13 is in contact with and conducted with the corresponding ground contact 222 through the first contact connection portion 24, so that the ground contact 222 and the shield 13 are in the same network, and distribution of the ground network is increased, thereby increasing a return path of a return current or a signal, and further reducing crosstalk between signals.
Further, referring to fig. 8 and 9, in the present embodiment, the electrical contact module 22 further includes:
and a ground shield piece 223, wherein the ground shield piece 223 is disposed at the side of the signal contact 221 and the ground contact 222, and the ground contact 222 and the ground shield piece 223 are electrically connected.
As shown in fig. 8 and 9, the ground shield 223 is located at the side of the ground contact 222 and the signal contact 221, and is electrically connected to the ground contact 222, and the signal contact 221 and the ground shield 223 are insulated from each other; the signal contact 221 includes a signal pin at the plugging area of the connector, the shield 13 and the ground shield 223 are conductive, and the signal pin and the shield 13 are not electrically connected. Here, the ground shield 223 may have a plate-like or sheet-like structure, and in this case, the ground shield 223 may cover the sides of the ground contact 222 and the signal contact 221, so as to provide electromagnetic shielding in the lateral direction for the signal contact 221.
Referring to fig. 8 and 9, in the electrical contact module 22 of the present embodiment, the signal contacts 221 and the ground contacts 222 may be alternately spaced from the ground shield 223. Specifically, the connector includes at least two electrical contact modules 22 arranged side by side, and the signal contacts 221 and the ground contacts 222 in the two electrical contact modules 22 are arranged alternately with the ground shield pieces 223, that is, a layer composed of the signal contacts 221 and the ground contacts 222 is sandwiched between the two ground shield pieces 223, or the ground shield pieces 223 is sandwiched between the two layers composed of the signal contacts 221 and the ground contacts 222. The ground shield 223 can provide a better ground shield on the side of the signal contact 221, and reduce the signal crosstalk between two adjacent electrical contact modules 22.
However, on the one hand, due to the limitation in size and number of the ground shield pieces 223 (i.e., the shield module in the related art) themselves, the ground shield pieces 223 have poor ground shielding effect on the signal contacts 221 adjacent to the edges of the ground shield pieces 223 in the electrical contact module 22; on the other hand, since the ground shield piece 223 is disposed at the side of the electrical contact module 22, it is difficult to achieve ground shielding of each signal contact 221 in a single electrical contact module 22, and signal crosstalk may also occur between each signal contact 221 in a single electrical contact module 22; on the last hand, poor contact between the ground shield 223 and the single ground contact 222 may occur, and thus, signal crosstalk may still occur in the signal contact 221.
At this time, in order to further improve the signal crosstalk resistance of the connector, the shielding member 131 is located on the side of the plugging region of the connector and is disposed around the periphery of the terminal group by the arrangement of the shielding member 13 in the first connector 1, so that when the first connector 1 and the second connector 2 are plugged and conducted, the signal pins of the pair of signal contacts 221 are plugged and conducted to the signal terminals 12 in the corresponding terminal group, and at the same time, the shielding members 13 are conducted to the ground shielding plate 223 and the ground contact 222 (i.e. the ground contact 222 and the ground shielding plate 223 are electrically connected to the shielding member 13), so that the connection of a plurality of shielding members 13 effectively avoids the poor contact between the single ground contact 22222 and the ground shielding plate 22323, and more importantly, the ground contact 222, the ground contact b, and the ground contact b in the single electric contact module 22, The grounding shield strips 223 and the shields 13 are in the same network, so that the distribution of the grounding network is increased, the return path of the return current is increased, a good return path is provided for the signal pairs, insertion loss resonance is reduced or avoided, crosstalk between adjacent signals (adjacent differential signal pairs) is reduced, and the integrity of signal transmission is improved.
For example, in order to maintain insulation between the signal pin and the shield 13, the signal pin and the shield 13 may be spaced apart from each other by a certain distance, so that the shield 13 and the signal pin are not in contact with each other, but are isolated from each other by air. Since air is a good insulating medium, the signal pins and the shield 13 can also be insulated from each other. Therefore, the shielding member 13 and the signal pin do not need to be connected through other parts, and the overall structure of the connector assembly is simple and reliable, and is convenient to process and manufacture.
For example, referring to fig. 8 and 9, in order to insulate the signal contact 221 and the ground shield 223, the present embodiment may provide a second insulating member 225 on the signal contact 221 and the ground shield 223, and the second insulating member 225 makes the signal contact 221 and the ground contact 222 not contact with each other and be in a spaced state, so as to achieve the insulating isolation between the signal contact 221 and the ground shield 223.
Further, referring to fig. 13, there are at least two second contact connection portions 25 between the shield 13 and each corresponding ground shield piece 223, the second contact connection portions 25 are connected between the shield 13 and the ground shield piece 223, and each second contact connection portion 25 is located on a different shield portion 131 of the shield 13.
Referring to fig. 13, after the first connector 1 and the second connector 2 are plugged, the shielding member 13 is connected to the corresponding ground shielding plate 223 through the second contact connection portion 25, so that an annular closed shielding structure is formed at the periphery of the terminal group, and the plugged area of the first connector 1 and the second connector 2 can be completely shielded, so as to suppress the reverse magnetic flux generated by the oscillating magnetic field energy due to impedance mismatch, enhance the isolation of the electric field energy, reduce the mutual inductance between the loops, reduce the inductive coupling noise, and reduce the crosstalk between adjacent signals, thereby improving the integrity of the signals during high-speed transmission.
In one possible implementation, the first contact connection 24 and/or the second contact connection 25 is a conductive dome.
In this embodiment, referring to fig. 13, the conductive elastic sheet may be disposed on the contact and the grounding shield 223 opposite to the electrical contact module 22. Specifically, the first contact connection portion 24 may be disposed on the ground contact 222, the second contact connection portion 25 may be disposed on the ground shield piece 223, and the first contact connection portion 24 and the ground contact 222, and the second contact connection portion 25 and the ground shield piece 223 may be an integrated structure. When the first connector 1 and the second connector 2 are plugged, the grounding contact piece 222 is connected with the corresponding shielding part 131 through the first contact connecting part 24, the grounding shielding piece 223 is connected with the different shielding part 131 of the shielding piece 13 through the second contact connecting part 25, and an annular closed shielding structure is formed on the periphery of the terminal group.
