Detailed Description

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:

connectors, generally referred to as electrical connectors, are devices used to connect two active devices, and when a connector is connected to two active devices, a current or signal can be transmitted between 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.

Fig. 2 is a schematic diagram of connection between a shield and an electrical contact module in a connector provided in an embodiment of the present application. Fig. 3 is a schematic structural diagram of an electrical contact module in a connector provided in an embodiment of the present application. Fig. 4 is a schematic cross-sectional view of a connector provided in an embodiment of the present application in a plugging direction. Fig. 5 is a schematic layout diagram of signal contacts and ground contacts in a connector according to an embodiment of the present application. Fig. 6 is a schematic structural diagram of a ground shield in a connector according to an embodiment of the present application. As shown in fig. 1 to 6, the connector in the present embodiment specifically includes a shield 1 capable of conducting electricity, and at least one electrical contact module 2. Each electrical contact module 2 comprises at least one signal contact 21, at least one ground contact 22 and at least one ground shield 23, the ground shield 23 is arranged at the side of the signal contact 21 and the ground contact 22, the signal contact 21 and the ground shield 23 are insulated, and the ground contact 22 and the ground shield 23 are electrically connected; the signal contact 21 includes a signal pin 211 located in the plugging area of the connector, the shielding element 1 is electrically connected to the ground shielding plate 23, the shielding element 1 is provided with a receiving area, the signal pin 211 passes through the receiving area, and the signal pin 211 is not electrically connected to the shielding element 1.

In the above connector, each electrical contact module 2 may have two different connection ends, for example, one of the connection ends of the electrical contact module 2 may be connected to a device such as a single board, and the other connection end may be used to be connected to a device such as a backplane, so as to implement electrical connection and signal transmission between the two devices.

Wherein each electrical contact module 2 can realize the electrical connection between the devices relatively independently. Therefore, the number of the electrical contact modules 2 in the connector may be one or more than one, and the number of the electrical contact modules 2 may vary according to the number and specifications of the devices to be electrically connected. Each electrical contact module 2 may, for example, be connected to a row or a column of pins on the device to be connected.

Specifically, each electrical contact module 2 includes a signal contact 21, a ground contact 22, and a ground shield 23. The signal contact 21 is used for signal transmission, and the ground contact 22 is used for ground isolation and shielding. The signal contacts 21 and the ground contacts 22 may have various structures and types for performing functions such as signal transmission or ground shielding. For example, in an alternative embodiment, the signal contact 21 may be a signal trace, and the ground contact 22 may be a ground line, or the signal contact 21 and the ground contact 22 may be both of a sheet-like or plate-like conductive connection structure. In this embodiment, the signal contact 21 is taken as a signal trace, and the ground contact 22 is taken as a ground line.

In order to make the connector electrically connect two devices, one end of the signal contact 21 and one end of the ground contact 22 extend from one of the connection ends of the connector and form a signal contact point and a ground contact point (the signal contact point and the ground contact point may be in a fish-eye structure), and the other end of the signal contact 21 and the ground contact 22 are located at the other connection end of the connector and form a signal pin 211 and a ground pin 221. The signal pins 211 and the ground pins 221 can be plugged into another connector, and the areas where the signal pins 211 and the ground pins 221 are located are plugging areas of the connector. Wherein, since the connector may be a male connector or a female connector, the signal pin 211 may be one of a male pin or a female pin as an alternative embodiment.

And to accomplish the transmission of one or more signals, the corresponding signal contacts 21 may be one or more, respectively. And the signal contacts 21 may be differential signal contacts or may be other types of signal contacts. Illustratively, the signal contacts 21 are differential signal contacts, in which case a plurality of signal contacts 21 may be arranged in pairs, and each pair of signal contacts 21 may be used to transmit a differential pair of signals.

Alternatively, the number of the ground contacts 22 in each electrical contact module 2 may be multiple, and the number of the ground contacts 22 may match the number of the signal contacts 21, for example, when the signal contacts 21 are differential signal contacts 21, a pair of signal contacts 21 for transmitting a differential signal pair may be matched with one ground contact 22, and the ground contact 22 may be located between the two signal contacts 21 or on the side of the two signal contacts 21.

Alternatively, the signal contacts 21 and the ground contacts 22 in each electrical contact module 2 may be arranged side by side in sequence. For example, the electrical contact module 2 may have a plate-like or sheet-like structure as a whole, and the signal contacts 21 and the ground contacts 22 on the electrical contact module 2 may be arranged side by side in the direction of the plate surface.

In order to avoid short circuit between the ground contact 22 and the signal contact 21, the ground contact 22 and the signal contact 21 need to be relatively insulated. Specifically, the signal contact 21 and the ground contact 22 may be arranged at an interval so that a certain distance is provided between the signal contact 21 and the ground contact 22, or an insulator may be arranged between the signal contact 21 and the ground contact 22 so as to achieve insulation and isolation between the signal contact 21 and the ground contact 22.

The ground shield 23 is located on the side of the ground contact 22 and the signal contact 21, and is electrically connected to the ground contact 22. The ground shield 23 may have a plate-like or sheet-like structure, and the ground shield 23 may cover the sides of the ground contacts 22 and the signal contacts 21, so as to provide electromagnetic shielding in the lateral direction for the signal contacts 21.

In the electrical contact module 2 of the present embodiment, the signal contacts 21 and the ground contacts 22 may be alternately spaced from the ground shield pieces 23. Specifically, the connector includes at least two electrical contact modules 2 arranged side by side, and the signal contacts 21 and the ground contacts 22 in the two electrical contact modules 2 are arranged alternately with the ground shield pieces 23, that is, a layer composed of the signal contacts 21 and the ground contacts 22 is sandwiched between the two ground shield pieces 23, or the ground shield pieces 23 are sandwiched between the two layers composed of the signal contacts 21 and the ground contacts 22. The ground shield 23 can provide a better ground shield at the side of the signal contact 21, and reduce the signal crosstalk between two adjacent electrical contact modules 2.

However, on the one hand, due to the limitations in size and number of the ground shield blades 23 themselves, the ground shield blades 23 have a poor ground shielding effect on the signal contacts 21 adjacent to the edges of the ground shield blades 23 in the electrical contact module 2; on the other hand, since the ground shield plate 23 is disposed at the side of the electrical contact module 2, it is difficult to achieve ground shielding of each signal contact 21 in a single electrical contact module 2, and signal crosstalk may also occur between each signal contact 21 in a single electrical contact module 2; on the last hand, poor contact between the ground shield 23 and the single ground contact 22 may occur, and thus signal crosstalk may still occur in the signal contact 21.

At this time, in order to further improve the signal crosstalk resistance of the connector, the connector further includes a shield 1, and the shield 1 is located at the plugging area side of the connector, that is, at one end having the signal pin 211 and the ground pin 221. And conduction between the shield 1 and the ground shield 23. Therefore, through the connection of the shielding element 1, the grounding contact pieces 22 and the grounding shielding sheets 23 in different electrical contact modules 2 are conducted and connected into a whole, on one hand, the phenomenon of poor contact between a single grounding contact piece 22 and the grounding shielding sheet 23 is effectively avoided, and more importantly, a plurality of grounding contact pieces 22 and grounding contact pieces are in the same network, which is equivalent to the increase of the distribution of the ground network, and the return current of signals needs to pass through the ground network, the distribution of the ground network is increased, which is equivalent to the increase of the return path of the return current, so that all signal pairs have complete and nearest return paths, the radiation effect of an electric field can be reduced, the crosstalk between signals is reduced, and the electric field radiation generated by insertion loss resonance and signal oscillation caused by impedance mismatching is inhibited.

Meanwhile, the shielding element 1 is provided with a hollow accommodating area, the signal pin 211 of the signal contact 21 passes through the accommodating area, and the signal pin 211 and the shielding element 1 are not electrically connected. Specifically, the signal pin 211 and the shield 1 may be insulated from each other, and if no specific description is given, the signal pin 211 and the shield 1 are all insulated from each other as an example. The signal pin 211 and the shield 1 may be spaced apart from each other or isolated from each other by another insulator, so as to avoid electrical connection between the signal pin 211 and the shield 1, such as conduction, contact, and the like.

At this time, in the case that the shielding element 1 is connected and conducted with the grounding shielding plate 23, since the receiving region is provided on the shielding element 1, the signal pin 211 can pass through the shielding element 1 from the receiving region without being interfered by the structure of the shielding element 1, or can be contacted and conducted with the shielding element 1. By arranging the accommodating area on the shielding part 1, on one hand, the signal pin 211 can normally extend out of the connector and can be plugged with other connectors or devices; on the other hand, a single signal pin 211 on the electrical contact module 2 is at least partially located in the accommodating area, and the outer side of the accommodating area is a structure formed by the shielding member 1, so that the signal pin 211 can be shielded and protected by the outer shielding member 1 in the circumferential direction of the signal pin 211, and the signal crosstalk resistance of the signal pin 211 is effectively improved.

Various possible configurations and embodiments of the various parts of the connector, such as the shield 1 and the electrical contact module 2, are explained in detail below.

Specifically, with respect to the shield 1, since the shield 1 needs to be conducted and grounded to the ground shield piece 23 and the ground contact 22, the shield 1 itself is a conductive conductor. Alternatively, the shielding element 1 may be made of metal, plastic with plated surface or conductive plastic, or other materials with conductivity known to those skilled in the art, so that the surface of the shielding element 1 has good conductivity, and the grounding contact 22 and the grounding shielding plate 23 can be conducted with each other when they are in contact with the shielding element 1.

The signal pins 211 of the signal contacts 21 may be insulated from the shield 1 in a number of different ways as the signal pins 211 pass through the receiving areas. As an alternative embodiment, the signal pin 211 of the signal contact 21 may be suspended in the receiving area of the shield 1.

In order to keep the signal pin 211 and the shielding element 1 insulated from each other, the signal pin 211 can be suspended in the accommodating area, and the shielding element 1 and the signal pin 211 are not in contact with each other but isolated from each other by air. Since air is a good insulating medium, the signal pin 211 and the shield 1 can also be insulated from each other. Meanwhile, the shielding part 1 and the signal pin 211 are not required to be connected through other parts, the whole structure of the connector is simple and reliable, and the connector is convenient to process and manufacture.

In addition, in other alternative embodiments, an insulating member may be disposed outside the signal pin 211, and the insulating member and the shielding member 1 are relatively fixed, so that the signal pin 211 may be fixed in the accommodating area of the shielding member 1 through the insulating member, and meanwhile, since the insulating member itself has an insulating capability, a short circuit or the like between the signal pin 211 and the shielding member 1 may not occur.

In order to fix the insulator on the shield 1, the insulator may be connected to the shield 1 by abutting, snapping, interference fitting, or other connection methods commonly used by those skilled in the art. The specific structure and shape of the insulating member may be set according to the size and shape of the accommodating area, and is not limited herein. Illustratively, the insulator may surround the circumferential outer side of the signal pin 211.

Alternatively, the insulating member may be made of an insulating material, and for example, the insulating member may be a plastic member or a resin member.

In order to form the accommodating area, optionally, the shielding element 1 may include an accommodating cavity 11, an accommodating area for the signal pin 211 to pass through is formed inside the accommodating cavity 11, and a space is formed between the cavity wall of the accommodating cavity 11 and the signal pin 211.

The inside of the accommodating cavity 11 may only pass through the signal pin 211, that is, the signal pin 211 is suspended, and at this time, no other spacer is disposed between the cavity wall of the accommodating cavity 11 and the signal pin 211, but insulation is achieved by virtue of a gap between the two. Or, besides the signal pin 211, an insulating member may be disposed inside the accommodating cavity 11, and the signal pin 211 is kept fixed and insulated relative to the cavity wall of the accommodating cavity 11 by the insulating member.

In order to allow the signal pin 211 to pass through the accommodating cavity 11, the accommodating cavity 11 may be a cavity with an opening, that is, both ends of the accommodating cavity 11 along the axial direction of the signal pin 211 are provided with openings, and the signal pin 211 can enter and pass through the two openings so as to penetrate through the accommodating cavity 11. And the cavity wall of the accommodating cavity 11 is positioned at the side of the signal pin 211, and the shielding and grounding functions are realized.

At this time, the cavity wall of the accommodating cavity 11 may be surrounded on the circumferential outer side of the signal pin 211, for example, as an optional accommodating cavity structure, the entire circumference of the signal pin 211 may be surrounded by the cavity wall of the accommodating cavity 11. Fig. 7 is an alternative structure diagram of a receiving cavity in a shielding element according to an embodiment of the present application. As shown in fig. 7, at this time, the outer sides of the signal pins 211 in different circumferential directions are surrounded by the accommodating cavity 11, so that the cavity wall of the accommodating cavity 11 can form a closed shielding structure in the circumferential direction of the signal pins 211, thereby realizing omnidirectional shielding of the signal pins 211 in the circumferential direction, and having better shielding and signal crosstalk reduction effects.

In another alternative accommodating cavity structure, a part of the circumferential direction of the signal pin 211 may be surrounded by the cavity wall of the accommodating cavity 11. Fig. 8 is a schematic structural diagram of another alternative accommodating cavity in the shielding element provided by the embodiment of the application. As shown in fig. 8, in the accommodating cavity 11 with such a structure, the accommodating cavity 11 has an opening at a lateral position of the signal pin 211, so that the cavity wall of the accommodating cavity 11 shields the signal pin 211 at a portion outside the opening. For example, an opening may be formed at a side of the accommodating cavity 11, so that only a part of the signal pins 211 in the circumferential direction is surrounded by the accommodating cavity 11, and the corresponding opening is not shielded. Therefore, on one hand, the shielding effect of the signal pin 211 is influenced by the size of the opening and the position of the opening, so that the signal pin 211 can have special shielding effect and characteristic through different sizes and shapes of the opening; on the other hand, after the opening is formed on the shielding member 1, the structure at the opening may be used in cooperation with other structures on the shielding member 1 or other components of the connector, for example, the shielding member 1 is fixed on the connector through the opening. The size and shape of the opening of the accommodating cavity 11 can be set according to the structure and actual needs of the shielding member 1.

The accommodating cavity 11 may be of various types according to the structure of the accommodating cavity 11. For example, when the signal pins 211 are circumferentially surrounded by the cavity wall of the accommodating cavity 11, correspondingly, the accommodating cavity 11 may be a through hole, at this time, the signal pins 211 may penetrate through the through hole from the directions of the two end surfaces of the through hole, and the hole wall of the through hole is surrounded by the side of the signal pins 211 and keeps a certain interval from the signal pins 211.

Wherein, the through-hole can be the straight hole, and the through-hole can be all the same for the cross section size of each position of axial, like this signal pin 211 each section in the through-hole all can with the through-hole pore wall between keep comparatively suitable interval, even the through-hole has longer axial length, signal pin 211 also can not touch each other with the pore wall of through-hole to have comparatively reliable insulating properties.

When only a part of the signal pins 211 in the circumferential direction is surrounded by the cavity wall of the accommodating cavity 11, correspondingly, the accommodating cavity 11 may be in the form of a through groove. At this time, the extending direction of the through groove is the same as or close to the axial direction of the signal pin 211, and the notch of the through groove is located at the side of the signal pin 211, so as to form an opening of the accommodating cavity 11. The axial direction of the signal pin 211 is the extending direction or the length direction of the signal pin 211.

Similar to the through hole, the through groove can also be a straight groove, and the cross sections of all parts of the through groove along the circumferential direction of the through groove have the same size.

When the accommodating cavity 11 is a through hole or a through groove, as an alternative, the extending direction of the through hole or the through groove may be the same as the extending direction of the signal pin 211. Therefore, the axial direction of the signal pin 211 is parallel to the extending direction of the through hole or the through groove, so that a constant distance is always kept between the signal pin 211 and the wall of the through hole or the through groove, even if the length of the signal pin 211 is long, the signal pin 211 cannot touch or interfere with the wall of the through hole or the wall of the through groove, and the phenomenon that the signal pin 211 is inclined to conduct with the shielding part 1 is avoided.

Furthermore, the cross-sectional shape of the receiving cavity 11 in the shield 1 in the direction perpendicular to the length direction of the signal pin 211 may be a variety of different shapes. For example, the cross-sectional shape of the receiving cavity 11 perpendicular to the axial direction of the signal pin 211 may be rectangular, circular, or elliptical. Thus, the cross-sectional shape of the accommodating cavity 11 is regular and symmetrical, and the distance between the signal pins 211 and the cavity wall of the accommodating cavity 11 is uniform. In the present embodiment, the cross-sectional shape of the accommodating chamber 11 is illustrated as a rectangle.

It should be noted that, when the accommodating cavity 11 is a through hole, the cross section of the through hole is the shape of the cross section of the accommodating cavity 11 in the direction. When the accommodating cavity 11 is a through groove, the shape enclosed by the opening edge of the through groove can be defined as the cross-sectional shape of the accommodating cavity 11 in the direction perpendicular to the length direction of the signal pin 211.

In the connector, the signal contacts 21 in the electrical contact module 2 may have a plurality to correspondingly transmit different signals. Accordingly, when there are a plurality of signal contacts 21, there are a plurality of signal pins 211, and there may be a larger space between different signal pins 211, and the single receiving cavity 11 has the following disadvantages: first, it may be difficult for a single receiving cavity 11 to simultaneously receive a plurality of signal pins 211; secondly, a plurality of signal pins 211 are all located in the same accommodating cavity 11, and the accommodating cavity 11 has a larger internal space, so that a larger distance may exist between the signal pins 211 and the cavity wall of the accommodating cavity 11, thereby affecting the shielding effect of the shielding element 1 on the signal pins 211. Thus, in order to avoid the above-mentioned drawback, as an alternative embodiment, the number of the receiving cavities 11 in the shielding member 1 is at least two, and the receiving cavities 11 are arranged at intervals along the radial direction of the signal pins 211.

When there are a plurality of signal contacts 21, the signal contacts 21 may be arranged side by side, and correspondingly, the signal pins 211 on the signal contacts 21 are also arranged side by side. At this time, the number of the accommodating cavities 11 is set to be more than one, so that the plurality of signal pins 211 can respectively penetrate through different accommodating cavities 11 on the shielding member 1. And the holding chamber 11 of the shielding member 1 can be arranged along the radial direction of the signal pins 211, that is, in the direction perpendicular to the axial direction of the signal pins 211 at intervals, so that the plurality of signal pins 211 arranged side by side can respectively pass through the holding chambers 11 with opposite positions, thereby a proper distance is provided between the signal pins 211 and the chamber wall of the holding chamber 11, and the holding chamber 11 can have a reasonable size and shape.

When the number of electrical contact modules 2 is greater than one, the shielding element 1 may also be of different types and configurations in order to provide shielding and the like for a plurality of electrical contact modules 2 at the same time.

For example, in an alternative structure, the connector may include a shield 1, and the shield 1 corresponds to a plurality of electrical contact modules 2 and performs a shielding function. At this time, the shielding member 1 may have at least two accommodating cavity groups, the accommodating cavity groups are disposed in one-to-one correspondence with the electrical contact modules 2, and different accommodating cavity groups are arranged at intervals along a first direction, wherein the first direction is perpendicular to the extending direction of the signal pins 211.

When a plurality of electrical contact modules 2 are included in the connector, only one shield 1 may be included in the connector, and the electrical contact modules 2 are all connected to the shield 1. At this time, in order to avoid and shield the signal pins 211 in different electrical contact modules 2, at least two accommodating cavity groups are provided on the shielding member 1, and each accommodating cavity group corresponds to one signal pin 211 of an electrical contact module 2. Each receiving cavity group may have one or more receiving cavities 11 therein, and the receiving cavities 11 may be penetrated by the signal pins 211 in the power contact module 2. Since there may be a relatively large number of signal contacts 21 in the electrical contact module 2, correspondingly, each receiving cavity group may include more than one receiving cavity 11, and the signal pins 211 on a plurality of different signal contacts 21 in the same electrical contact module 2 pass through a plurality of different receiving cavities 11.

Because a plurality of electrical contact modules 2 can be arranged in parallel, correspondingly, a plurality of accommodating cavity groups are arranged at intervals along the same direction for corresponding connection with each electrical contact module 2. For example, the receiving cavities may be arranged along a first direction perpendicular to the extending direction of the signal pins 211. In this way, a plurality of electrical contact modules 2 are also arranged side by side along the first direction, and the electrical contact modules 2 are all located on the same side with respect to the shield 1 and maintain the same relative height and distance with respect to the shield 1. Through this mode of setting up, can make in the electric contact module 2, the signal pin 211 of signal contact 21 all can stretch out to shielding part 1 one side, and the signal pin 211 of signal contact 21 in the electric contact module 2 also can be relative with the holding chamber group position that corresponds to pass inside the holding chamber 11 of this holding chamber group, thereby obtain shielding part 1's shielding, improve the anti signal crosstalk ability of signal pin 211.

The spacing between the accommodating cavity groups may be the same or different, and the specific spacing size may be determined according to the size and type of the electrical contact module 2, which is not limited herein.

When the accommodating cavity group includes more than one accommodating cavity 11, in order to keep each accommodating cavity 11 in the same accommodating cavity group and each signal pin 211 in the electrical contact module 2 at a proper distance, optionally, at least two accommodating cavities 11 arranged at intervals along the second direction may be included in the accommodating cavity group. It should be noted that the first direction and the second direction are both located in a plane perpendicular to the extending direction of the signal pins 211, and the first direction and the second direction are also perpendicular to each other.

Specifically, in the electrical contact module 2, the signal contacts 21 are sequentially arranged along a certain direction at intervals, so that the signal pins 211 corresponding to the signal contacts 21 are also sequentially arranged along the certain direction at intervals and in parallel. Therefore, corresponding to the arrangement of the signal pins 211, the accommodating cavities 11 in the same accommodating cavity group may also be arranged at intervals along the arrangement direction of the signal pins 211. At this time, the second direction may be determined as the spaced arrangement direction of the signal pins 211 in the same electrical contact module 2.

In the case where the electrical contact module 2 has a generally thin-layer structure, a plurality of electrical contact modules 2 may be arranged side by side in the thickness direction of the electrical contact module 2; the arrangement direction of the signal pins 211 in each electrical contact module 2 is along the plane direction of the electrical contact module 2, i.e. the direction perpendicular to the thickness direction of the electrical contact module 2. Therefore, it can be easily known that, since the arrangement direction of the receiving cavities 11 corresponds to the arrangement direction of the signal pins 211, the receiving cavities 11 are also arranged at intervals along a second direction perpendicular to the first direction, i.e. the plane direction of the electrical contact module 2.

In this embodiment, a plurality of electrical contact module 2 are connected simultaneously to shield 1 in the connector, and the holding chamber group that corresponds every electrical contact module 2 on shield 1 is including more than one, and when the same holding chamber 11 of quantity, each holding chamber 11 in shield 1 can be the matrix arrangement of regularity. Accordingly, the overall structure of the shield 1 may be square or the like.

However, it will be understood by those skilled in the art that when a plurality of electrical contact modules 2 are included in the connector, different electrical contact modules 2 may have different signal connection modes, and thus different electrical contact modules 2 may have different numbers of signal pins 211. Correspondingly, among the plurality of accommodating cavity groups arranged on the shielding member 1, different accommodating cavity groups may also include accommodating cavities 11 with different arrangement modes and structures. For example, the number of the accommodating cavities 11 included in different accommodating cavity groups on the shielding member 1 may be different, for example, one accommodating cavity group has 3 accommodating cavities 11, and the other accommodating cavity groups include 4 accommodating cavities 11; the number of the accommodating cavities 11 included in different accommodating cavity groups on the shielding member 1 may also be the same, but the accommodating cavities 11 have different sizes, for example, the size and the size of the accommodating cavity 11 in one accommodating cavity group are smaller than the size of the accommodating cavity 11 in other accommodating cavity groups; or the number and size of the accommodating cavities 11 of different accommodating cavity groups on the shielding member 1 are the same, but the accommodating cavities 11 in different accommodating cavity groups have different size intervals, so that different accommodating cavity positions and the like are formed in different accommodating cavities 11; or, at least two of the number of the accommodating cavities 11, the size of the accommodating cavities 11, and the positions of the accommodating cavities 11 in different accommodating cavity groups on the shielding member 1 may be different, so that accommodating cavity groups with different arrangement modes are formed in the shielding member 1, which is not described herein again.

In a plurality of holding cavity groups in the shielding part 1, different holding cavity groups have the same or different arrangement modes and structures, so that the shielding part 1 can be connected with a plurality of electric contact modules 2 with the same or different models, and the connector can meet the wiring modes of various different types and specifications.

And let only include a shield 1 in the connector, and the mode that a plurality of electric contact module 2 all are connected with this shield 1, shield 1 can regard as a plurality of electric contact module 2's public link and public bearing structure, and the structural integrity of connector is better, and has higher structural strength, and the reliability is higher.

In yet another alternative embodiment, it is also possible to provide a connector with a plurality of shields 1, and to connect a plurality of electrical contact modules 2 to different shields 1. In the connector of the present embodiment, the number of the shielding members 1 may be the same as the number of the electrical contact modules 2, the electrical contact modules 2 are arranged in parallel, and the positions of the shielding members 1 correspond to the positions of the electrical contact modules 2.

In particular, when the number of the electrical contact modules 2 of the connector is plural, each electrical contact module 2 can be correspondingly connected with a corresponding shielding member 1. For example, similar to the embodiment where a plurality of electrical contact modules 2 are connected to the shielding member 1, the electrical contact modules 2 may also be arranged in parallel, and the signal pin 211 of each electrical contact module 2 is connected to an independent shielding member 1, that is, each electrical contact module 2 performs a shielding function through an independent shielding member 1. Like this every shielding 1 all sets up independently, and single shielding 1 has less volume, and the setting and the use of shielding 1 are comparatively nimble, are convenient for adjust.

At this time, since the plurality of electrical contact modules 2 are arranged in parallel, the shields 1 corresponding to the electrical contact modules 2 one by one are also arranged in parallel. And can be through the connection structure interconnect that shielding 1 self has between a plurality of shielding 1, also can be after a plurality of shielding 1 draw close each other and arrange side by side, fixed and interconnect are unified to the unified completion of other fixed knot structure of rethread. The relative fixing manner between the shields 1 may be a connection manner commonly used by those skilled in the art, such as abutting, clamping, fastener connection, etc., and is not limited herein.

Since the electrical contact module 2 may be a thin sheet or a thin layer structure, accordingly, the shielding member 1 corresponding to the electrical contact module 2 may be a strip structure, and the length direction of the shielding member 1 is consistent with the plane direction of the electrical contact module 2. When the shielding member 1 shields the signal pins 211 of the electrical contact modules 2, the structure of the shielding member 1 itself does not have much influence on the side-by-side arrangement of the electrical contact modules 2, and a small distance can be kept between a plurality of electrical contact modules 2 in the connector, so that the structure of the connector is compact.

When the shielding element 1 is provided in plural and corresponds to the electrical contact module 2 one by one, the accommodating cavity 11 on the shielding element 1 may also be one or more and corresponds to the electrical contact module 2 connected to the shielding element 1. Specifically, similar to the embodiment in which a plurality of electrical contact modules 2 are connected to the shielding member 1, in the electrical contact modules 2, the signal contacts 21 are sequentially arranged at intervals along a certain direction, so that the signal pins 211 corresponding to the signal contacts 21 are also sequentially arranged at intervals and in parallel along the certain direction. Therefore, when the same shielding element 1 includes more than one receiving cavity 11, the receiving cavities 11 may also be sequentially arranged at intervals along the arrangement direction of the signal pins 211.

Furthermore, it will be understood by those skilled in the art that when a plurality of electrical contact modules 2 are included in the connector, different electrical contact modules 2 may have different numbers of signal pins 211 since different electrical contact modules 2 may have different signal connection manners, and correspondingly, different accommodating cavities 11 on different shields 1 in the connector may also include different arrangements and structures. By way of example, it is possible to have different shields 1 comprising different numbers of housing cavities 11; the number of the accommodating cavities 11 included in different shields 1 may be the same, but the accommodating cavities 11 have different sizes; or the number and the size of the accommodating cavities 11 on different shields 1 are the same, but the accommodating cavities 11 of different shields 1 have different size intervals, positions and the like; still alternatively, at least two of the number of the accommodating cavities 11, the size of the accommodating cavities 11 and the positions of the accommodating cavities 11 in different shields 1 may not be equal. The specific differences in the arrangement have been explained in detail in the case where the connector includes one shield 1, and are not described in detail here.

In addition, in addition to the above two modes, the connector may include a plurality of shields 1, and the plurality of shields 1 include both a case where the same shield 1 is connected to a plurality of different electrical contact modules 2 and a case where one shield 1 is connected to one electrical contact module 2. In this case, the specific structure of the shield 1 and the electrical contact module 2 in the connector can refer to the above two modes, and the details are not repeated here.

In addition, the number of signal pins 211 that can be accommodated in the accommodating cavity 11 of the shielding member 1 can also be set according to the structure and usage requirements of the connector. For example, as an alternative embodiment, at least two signal pins 211 are arranged in each accommodating cavity 11.

Specifically, because the accommodating cavity 11 can provide shielding and protection in the circumferential direction of the signal pins 211, even if the number of the signal pins 211 in the accommodating cavity 11 is greater than one, the accommodating cavity 11 can also ensure to surround the circumferential outer side of the signal pins 211, so that the signal of the signal pins 211 is shielded by the wall of the accommodating cavity 11. Therefore, the number of the signal pins 211 in each receiving cavity 11 may be greater than one, for example, the number of the signal pins 211 in the receiving cavity 11 is two or more. Thus, when the number of signal contacts 21 in the electrical contact module 2 is large, even if the space on the shielding member 1 is limited, so that the number of the accommodating cavities 11 on the shielding member 1 is small, the signal pins 211 on the connector can be shielded and protected by the accommodating cavities 11.

Among other things, since in the electrical contact module 2 the signal contacts 21 can be used to transmit differential signal pairs, the signal contacts 21 in the electrical contact module 2 can be arranged in pairs. Accordingly, as an alternative structure, each receiving cavity 11 of the shielding member 1 can also receive two signal pins 211. At this time, the two signal pins 211 may be respectively used to transmit two different signals in one differential signal pair.

Specifically, two signal pins 211 are accommodated in the same accommodating cavity 11, and signals transmitted by the two signal pins 211 are from the same differential signal pair, that is, the two signal pins 211 respectively transmit two signals with the same amplitude but opposite polarities. Therefore, when the two signal pins 211 are located in the same accommodating cavity 11, the mutual interference between the two signal pins 211 is small, so that the accommodating cavity 11 plays a good protective shielding role for the signal pins 211, and the mutual interference between the two signal pins 211 for transmitting differential signals is small.

While in the connector each electrical contact module 2 itself may likewise have a number of different configurations and types. For example, since the signal contact 21 is to be insulated from both the ground contact 22 and the ground shield 23 in the electrical contact module 2, a structure for isolating the signal contact 21 from the ground contact 22 and the ground shield 23 needs to be provided inside the electrical contact module 2. Wherein, in an alternative embodiment, the electrical contact module 2 comprises an insulating support 24, the insulating support 24 being supported between the signal contacts 21 and the ground shield 23.

Since the ground shield piece 23 and the ground contact 22 are electrically connected to each other and grounded, and the ground shield piece 23 covers the sides of the signal contact 21 and the ground contact 22, an insulating support 24 having an insulating property may be provided between the signal contact 21 and the ground shield piece 23 to isolate and insulate the signal contact 21 and the ground shield piece 23 from each other.

The insulating support 24 may be made of an insulating material, such as a non-conductive plastic material, to form the insulating support 24.

At this time, the signal contact 21 and the ground contact 22 may be respectively disposed at different positions on the ground shield 23, so that a gap is formed between the signal contact 21 and the ground contact 22, and the signal contact 21 and the ground contact 22 are insulated from each other by air; alternatively, the signal contact 21 and the ground contact 22 may be insulated and isolated from each other by an insulator, for example, the signal contact 21 and the ground contact 22 are isolated from each other by the insulating support 24.

Wherein the insulating support 24 may also have a variety of different configurations. For example, the insulating support 24 may partially or completely surround the outside of the signal contact 21. At this time, the signal contact 21 is located inside the insulating support 24, and the outside is protected and isolated by the insulating support 24 without contacting the ground contact 22 and the ground shield 23.

Specifically, in order to surround the signal contact 21, the insulating support 24 may be provided with a cavity or a groove, and the signal contact 21 may be placed in the cavity or the groove and isolated from the ground contact 22 and the ground shield 23 outside the insulating support 24, so as to prevent the signal contact 21 from being conducted with the ground contact 22 or the ground shield 23. Alternatively, the insulating support 24 may be surrounded on the outside of the signal contact 21 by injection molding or the like, thereby insulating the signal contact 21 from the ground contact 22 and the ground shield 23.

Furthermore, the insulating support 24 may be isolated only between the signal contact 21 and the ground shield 23, and the signal contact 21 and the ground contact 22 may be insulated from each other by providing a gap therebetween. Specifically, the signal contact 21 may be provided with a fixing structure such as a positioning groove, so that the signal contact 21 is fixed on the insulating support 24, and the insulating support 24 and the ground contact 22 are respectively fixed at different positions of the ground shield 23. Furthermore, the insulated contact may have other different structures and shapes as long as the insulated contact can achieve the insulation and isolation between the signal contact 21 and the ground shield 23, and the like, and is not limited herein.

And, in order to fix and isolate the signal contacts 21 and the ground contacts 22, the ground shield sheet 23 may alternatively have an uneven plate surface. At this time, the ground shield 23 has a plurality of protruding regions 231 in a direction perpendicular to the thickness direction thereof, and the protruding regions 231 are spaced apart from each other, so that a recessed region 232 is formed between every two adjacent protruding regions 231. This makes it possible to arrange the signal contacts 21 and the ground contacts 22 in different areas on the ground shield 23, respectively.

Wherein the signal contact 21 may be disposed in the recessed area 232 of the ground shield 23 and the ground contact 22 may be disposed in the raised area 231 of the ground shield 23. Since the directions of the grounding shield sheet 23 and the whole electrical contact module 2 are parallel to each other, the signal contact 21 is disposed in the recessed area 232 of the grounding shield sheet 23, and the signal contact 21 is protected by the concave-convex structure of the grounding shield sheet 23, so that the exposure of the signal contact 21 is reduced, and the signal insulation member has more reliable insulation performance.

Specifically, the recessed area 232 and the raised area 231 of the ground shield 23 may extend along the length direction of the signal contact 21 or the ground contact 22, so as to form a shape and a size that are matched with the shape of the signal contact 21 or the ground contact 22. The recessed area 232 and the raised area 231 of the ground shield 23 can limit and fix the signal contact 21 or the ground contact 22 by their own shape.

In order to fix the ground shield 23 and the shield 1, the edge of the ground shield 23 facing the shield 1 may have a shape matching the shape of the shield 1, and the ground shield 23 abuts against the shield 1.

At this time, since the edge of the ground shield piece 23 abuts against the shield 1 and conduction connection is achieved, when the shape of the edge of the ground shield piece 23 facing the shield 1 and the shape of the surface of the shield 1 match each other, the contact surface between the ground shield piece 23 and the shield 1 extends in a plurality of different directions, and even if the ground shield piece 23 is displaced and moved in a certain direction with respect to the shield 1, the ground shield piece 23 can be kept in contact with the shield 1. Meanwhile, the contact part of the grounding shield sheet 23, which can be in contact with the shield 1, has a longer length and a larger contact area, and effective conduction between the grounding shield sheet 23 and the contact can be realized.

Illustratively, since the shielding element 1 is provided with the accommodating cavity 11, and the accommodating cavity 11 is in the shape of a through hole or a through groove, the shape of the edge of the grounding shielding sheet 23 may correspondingly be uneven, and the edge protruding outwards may extend into the accommodating cavity 11; the edge of the recess is located at the outer part of the accommodating cavity 11 and is abutted with the outer surface of the shielding element 1.

Specifically, in an alternative embodiment, the edge of the grounding shield 23 facing the shield 1 has at least two protrusions spaced apart from each other, and the protrusions extend into the corresponding accommodating cavities 11 and contact the cavity walls of the accommodating cavities 11. The size and shape of the protruding portion may be matched with the shape of the accommodating cavity 11, for example, the width of the protruding portion is matched with the size of the accommodating cavity 11, so that the protruding portion is clamped into the accommodating cavity 11.

The edge of the ground shield 23 facing the shield 1 may have other shapes, for example, the edge of the ground shield 23 may have a snap structure capable of connecting with the shield 1, and the invention is not limited thereto.

In order to support the structures such as the electrical contact module 2 and the shielding member 1 and enable the connector to be normally plugged, the connector may further include an insulating base. Fig. 9a is a schematic front structural view of an insulating base in an embodiment of the present application. Fig. 9b is a schematic diagram of a reverse structure of the insulating base in the embodiment of the present application. Fig. 10 is a schematic structural view of a connector with an insulating base according to an embodiment of the present application. As shown in fig. 9a, 9b and 10, the connector further includes an insulating base 3, and the insulating base 3 is disposed outside the plugging area of the connector.

In particular, the insulating base 3 may be a semi-enclosed housing structure as a whole to protect the electrical contact module 2 and the shield 1. In particular, the insulating base 3 may be constituted by one or more frame-shaped elements 31. The frame-shaped part 31 surrounds the outer sides of the electrical contact module 2 and the shield 1, with the inner side of the frame-shaped part 31 facing the electrical contact module 2 and the shield 1 and the outer side of the frame-shaped part 31 facing the structure or device to be mated with the connector. When the insulating base 3 is formed by a plurality of frame-shaped elements 31, the plurality of frame-shaped elements 31 may be arranged side by side, and each frame-shaped element 31 is located in correspondence with one electrical contact module 2.

In order to avoid affecting the normal plug connection of the signal contact 21 and the ground contact 22 in the connector, the frame 31 in the insulating base 3 may include an avoiding hole 311 for the signal pin 211 or other pins to pass through, because the insulating base 3 is located outside the plugging area of the connector. Thus, the signal pin 211 can pass through the avoiding hole 311 and be supported and fixed by the wall of the avoiding hole 311. The avoiding holes 311 are opposite to the signal pins 211 and the ground pins 221 on the connector, so that the signal pins 211 and the ground pins 221 can penetrate from the inner side of the frame-shaped member 31 to the outer side of the frame-shaped member 31. Alternatively, the avoiding holes 311 may be provided in one-to-one correspondence with the pins. Illustratively, the avoiding holes 311 may be arranged in an array on the insulating base 3.

The insulating base 3 is made of an insulating material in order to insulate other components from each other. Alternatively, the frame member 31 and the like in the insulating base 3 may be made of insulating plastic. Illustratively, the insulating base 3 may be formed by injection molding of a material such as Liquid Crystal Polymer (LCP).

In this embodiment, the first circuit component and the second circuit component may be a plurality of different devices or components, respectively. For example, when the electronic device is a backplane interconnection system, the first circuit component may be a backplane, and the second circuit component is a single board, and the single board and the backplane are interconnected through a connector. Alternatively, the first circuit component and the second circuit component may be single boards, and the two circuit components are connected to each other through a connector. Further alternatively, the first circuit component and the second circuit component may be both modular units, or the first circuit component is a circuit board, and the second circuit component is a chip, etc., where the specific type of the first circuit component and the second circuit component is not limited.
