This application relates to the field of electronic devices, and in particular, to a connector and an electronic device provided with the connector.
A connector is an apparatus that connects to an electrical terminal to form a circuit. The connector may be used to connect a wire, a cable, and a printed circuit board, to an electronic component, and transmit data, power, and a signal. Usually, a metallic shielding sheet or a conductive plastic is used in the connector to improve signal current return and isolate signal crosstalk.
For high-speed electrical signal transmission, crosstalk performance of the connector has important impact on transmission performance of a high-speed link. For a high-speed pluggable connector, signal current return is prone to generate on a mating surface between components on two sides of the connector, and the signal current return is a crosstalk source of the entire high-speed link.
An objective of this application is to provide a connector. A structure of a mating surface of the connector is improved, to improve an anti-crosstalk capability of the connector. In addition, this application further relates to an electronic device provided with the connector.
According to a first aspect, this application relates to a connector, including a socket assembly and a plug assembly. The socket assembly and the plug assembly are detachably connected. The socket assembly includes at least one connecting base. The connecting base includes a signal port and a shielding structure. The shielding structure is disposed around a peripheral edge of the signal port and forms one opening. The plug assembly includes at least one connecting head. The connecting head includes a signal terminal and a ground component. The signal terminal and the ground component are disposed side by side. When the plug assembly is fixedly connected to the socket assembly, each connecting head extends into one connecting base from one opening, the signal terminal is conducted to the signal port, and the ground component is bonded to the shielding structure.
The connector in this application includes the socket assembly and the plug assembly. The socket assembly and the plug assembly are detachably connected to form a pluggable function of the connector. The socket assembly and the plug assembly also form a mating surface of the connector. The socket assembly and the plug assembly form signal transmission in a mating surface area. In this application, the connector is provided with the shielding structure on the socket assembly, to prevent signal crosstalk that may occur when the connecting base of the socket assembly and the connecting head of the plug assembly are matched. The signal terminal and the ground component are arranged side by side in the connecting head of the plug assembly. When the plug assembly is fixedly connected to the socket assembly, the signal terminal is connected and conducted to the signal port, to implement signal transmission. The shielding structure is disposed around peripheral edges of the signal terminal and the signal port, and forms bonding with the ground component, to form reliable shielding effect on the mating surface. This may effectively prevent a phenomenon of signal current return, avoids impact of crosstalk resonance, and improves signal transmission integrity of the connector.
In a possible implementation, a quantity of connecting heads in the plug assembly is less than or equal to a quantity of connecting bases in the socket assembly.
In this implementation, setting of the quantity of connecting heads and the quantity of connecting bases may ensure that each connecting head can correspondingly extend into one connecting base. In this case, a phenomenon of connection interference between the plug assembly and the socket assembly does not occur because the quantity of connecting heads is not greater than the quantity of connecting bases.
In a possible implementation, the connector further includes a connecting piece. The connecting piece is located in the socket assembly. The socket assembly includes a plurality of connecting bases. The connecting piece is configured to be in contact with and conducted to each connecting base; and/or the connecting piece is located in the plug assembly. The plug assembly includes a plurality of connecting heads. The connecting piece is configured to be in contact with and conducted to each connecting head.
In this implementation, corresponding to a case in which a plurality of connecting bases are disposed in the socket assembly, the plurality of connecting bases need to form bonding, so that potentials of all shielding structures are equal. The foregoing function may be implemented by connecting the connecting piece to the shielding structures of each socket assembly. Correspondingly, a plurality of connecting heads are also disposed in the plug assembly. Similar effect can also be achieved by connecting the connecting piece to a ground component of each plug assembly.
In a possible implementation, the socket assembly includes a first shielding plate, a second shielding plate, and a plurality of spacer plates. The first shielding plate and the second shielding plate are in parallel and are fastened at an interval. The spacer plate is connected between the first shielding plate and the second shielding plate. The plurality of spacer plates are disposed at intervals in a length direction of the first shielding plate. One signal port is disposed between two adjacent spacer plates.
In this implementation, the first shielding plate, the second shielding plate, and the two adjacent spacer plates jointly form a shielding structure of one signal port. Shielding structures are sequentially connected at peripheral edge positions of signal ports, and form openings that allow connecting heads to enter. In addition, a plurality of signal ports may be disposed side by side in the length direction of the first shielding plate, and are arranged neatly.
In a possible implementation, the socket assembly includes a third shielding plate. The third shielding plate is located on one side that is of the second shielding plate and that is away from the first shielding plate, and is fastened to the second shielding plate at an interval. The spacer plate is connected between the second shielding plate and the third shielding plate, and the plurality of spacer plates are disposed at intervals in a length direction of the second shielding plate.
In this implementation, the connecting bases in the socket assembly are arranged in an array. The plurality of signal ports are arranged more neatly and are easy to manufacture. The second shielding plate may separately cooperate with the first shielding plate and the third shielding plate, to simultaneously form parts of shielding structures of two signal ports.
In a possible implementation, a protruding part is disposed on the spacer plate. The protruding part extends out in a direction towards the signal port. The protruding part is configured to reinforce bonding between the ground component and the shielding structure.
In this implementation, to avoid poor contact between the shielding structure of the connecting base and the ground component of the connecting head, the protruding part is disposed on the spacer plate of the connecting base. The protruding part may abut against the ground component, to maintain bonding and contact between the shielding structure and the ground component.
In a possible implementation, the ground component includes two ground parts. The two ground parts are respectively arranged on two sides of the signal terminal. Each ground part is configured to contact one spacer plate, to form bonding between the ground component and the shielding structure.
In this implementation, when the ground component is implemented by using two ground parts, each of the two ground parts may be bonded to one spacer plate from the two sides of the signal terminal, to form contact. Bonding structures on the two sides may improve reliability of bonding and conduction between the ground component and the shielding structure.
In a possible implementation, the ground component further includes a connecting part. The connecting part bypasses the signal terminal and is connected between the two ground parts.
In this implementation, the connecting part is connected between the two ground parts. This may enhance overall rigidity of the connecting piece, and avoid a phenomenon of poor bonding caused by deformation of the two ground parts.
In a possible implementation, the connecting piece is located in the plug assembly. The connecting piece includes a plurality of windows. Each ground component passes through one window and extends out. A protruding dot is further disposed in the window. The protruding dot abuts against the ground component, to ensure that the connecting piece is in contact with and conducted to each connecting head.
In this implementation, the connecting piece is disposed on one side of the plug assembly. This simplifies a structure of the connecting piece and facilitate manufacturing. In addition, when the connecting head extends into the connecting base, the connecting piece may be located outside the shielding structure. This does not affect a connection and fastening between the socket assembly and the plug assembly.
In a possible implementation, the signal port includes two conductive plates. The two conductive plates are disposed at an interval. Correspondingly, the signal terminal includes two conductive pins. The two conductive pins are also disposed at an interval, and each conductive pin is configured to be conducted to one conductive plate. The signal port and the signal terminal are configured to transmit a differential signal.
In this implementation, both a signal port and a signal terminal are configured to transmit the differential signal. A voltage difference is formed between two groups of conductive pins and conductive plates, and a signal transmission function is formed by transmitting the voltage difference.
In a possible implementation, the plug assembly includes a plug body. The conductive pin includes a first section and a second section. The first section is exposed from the plug body, the second section is accommodated in the plug body, and an outline size of the first section is greater than an outline size of the second section.
In this implementation, due to a conductivity difference between surrounding media of the first section and the second section, outline sizes of the first section and the second section are set to be different. This helps adjust impedance matching between the first section and the second section, and can also avoid signal crosstalk.
According to a second aspect, two functional components and the connector according to any one of claims 1 to 10 connected between the two functional components are included.
It may be understood that, because the electronic device in this application is provided with the foregoing connector, the plug assembly and the socket assembly may be respectively disposed in the two functional components of the electronic device in this application, and better signal transmission integrity and reliability are obtained due to a shielding capability of the foregoing connector.

With reference to
The spacer plate 224 is connected between the upper shielding plate 222 and the lower shielding plate 223. The spacer plate 224 is clamped to both the upper shielding plate 222 and the lower shielding plate 223. A quantity of spacer plates 224 is one more than a quantity of signal ports 221. Two adjacent spacer plates 224 are also respectively arranged on the two opposite sides of the signal port 221. Alternatively, the spacer plate 224 includes two end spacer plates 2241 and a middle spacer plate 2242 located between the two end spacer plates 2241. The end spacer plate 2241 and the middle spacer plate 2242 are disposed at an interval, and two adjacent middle spacer plates 2242 are disposed at an interval, so that one signal port 221 is accommodated between any two spacer plates 224.

The ground component 122 includes a ground part 1221. The ground part 1221 and the signal terminal 121 are disposed side by side. In the embodiment shown in the figure, each connecting head 120 includes two ground parts 1221. The two ground parts 1221 are respectively arranged on two opposite sides of the signal terminal 121. In the embodiment shown in the figure, the ground component 122 further includes a connecting part 1222. The connecting part 1222 crosses the signal terminal 121 and is connected between the two ground parts 1221. The connecting part 1222 is configured to connect and fasten the two ground parts 1221, to improve structural stability of the ground component 122. It may be understood that the connecting part 1222 may prevent the two ground parts 1221 from deforming relative to the signal terminal 121.
In addition, the ground component 122 of each connecting head 120 is also bonded and conducted to the shielding structure of the connecting base 220. The shielding structure is disposed around the peripheral edge of the connection port 221. Therefore, after the ground component 122 is conducted to the shielding structure, a mating surface area formed by the connection terminal 121 and the connection port 221 is also accommodated in the shielding structure. The ground component 122 may be conducted to one or more of the upper shielding plate 222, the lower shielding plate 223, and the spacer plate 224. For example, refer to
Therefore, in the connector 300 of this application, when the plug assembly 100 is fixedly connected to the socket assembly 200, a group of ground part 122 and shielding structure are correspondingly bonded and conducted to peripheral edges of one signal terminal 121 and one signal port 221 that are in contact with and conducted to each other. The ground component 122 and the shielding structure that are bonded and conducted implement potential balance between the connecting head 120 and the connecting base 220. The shielding structure surrounds the mating surface, to block crosstalk impact that may be caused by an external signal on the mating surface. Cooperation between the shielding structure and the ground component 122 improves signal transmission integrity at each mating surface of the connector 300 in this application, so that signal transmission quality is higher, and a phenomenon of signal current return is effectively prevented.
For an embodiment, refer to
Therefore, when the connecting head 120 extends into the connecting base 220 from the opening 225, the ground component 122 of the connecting head 120 is in contact with the surface, and forms bonding and conduction. In this case, the protruding part 2241b protrudes relative to the surface, so that the protruding part 2241b may abut against the ground part 1221 of the ground component 122. The ground part 1221 compresses the protruding part 2241b, and the protruding part 2241b changes its shape, to ensure that the ground component 122 smoothly extends. It may be understood that the protruding part 2241b changes its shape towards a direction away from the signal port 221. Therefore, the protruding part 2241b forms resilience in a direction towards the signal port 221. Under action of the resilience, the protruding part 2241b maintains abutting pressure on the ground part 1221. This may ensure reliable bonding between the ground component 122 and the shielding structure. In the embodiment shown in the figure, there are two protruding parts 2241b on the end spacer plate 2241, and the two protruding parts 2241b are arranged at an interval in a length direction of the end spacer plate 2241. In some other embodiments, there may be one or more protruding parts 2241b, and when there are a plurality of protruding parts 2241b, an arrangement manner of the protruding parts 2241b may also be randomly selected. This does not affect a specific implementation of this embodiment.
In an embodiment, the middle spacer plate 2242 may also be implemented in a form of two sub-spacer plates 2243. The two sub-spacer plates 2243 are disposed side by side, and the clamping part 2242a is disposed on each of the two sub-spacer plates 2243. In addition, the protruding parts 2242b on the two sub-spacer plates 2243 respectively extend out in opposite directions away from each other. That is, a protruding part 2242b on one sub-spacer plate 2243 protrudes towards a signal port 221 on one side, a protruding part 2242b on the other sub-spacer plate 2243 protrudes towards an opposite side, and the opposite side is close to the other signal port 221. The two sub-spacer plates 2243 are arranged side by side to form a structure of the middle spacer plate 2242. This facilitates manufacturing of each protruding part 2242b and ensures a distance between the middle spacer plate 2242 and each of the two signal ports 221.
It may be understood that structures of the protruding part 2241b and the protruding part 2242b may be further applied to a position of the upper shielding plate 222 and/or the lower shielding plate 223, that is, a structure of the protruding part 2241b is disposed on a surface that is of the upper shielding plate 222 and that faces the signal port 221, and/or a structure of the protruding part 2241b is disposed on a surface that is of the lower shielding plate 223 and that faces the signal port 221. The structure may be configured to abut against a connecting part 1222 of a ground component 122 corresponding to the structure, to reinforce bonding and conduction between the shielding structure and the ground component 122. In some other embodiments, the structure of the protruding part may also be disposed on the ground component 122. Alternatively, the structure of the protruding part is disposed on each of the ground component 122 and the shielding structure.
It should be noted that, as shown in
In addition, the upper shielding plate 222 is simultaneously used as a shielding structure of the plurality of signal ports 221, and the lower shielding plate 223 is also simultaneously used as a shielding structure of the plurality of signal ports 221. This may implement potential balance between the shielding structures. That is, for a same row of connecting bases 220, the shielding structures are sequentially conducted due to action of the upper shielding plate 222 and the lower shielding plate 223, and potentials of the shielding structures are the same. This helps prevent signal current return, and prevents crosstalk of a low-frequency signal. After the shielding plates of the two adjacent split body structures are integrally formed, the shielding structures in the two adjacent split body structures are also conducted to each other, and the potentials of the shielding structures are balanced. A plurality of split body structures are sequentially arranged, and the spacer plate 224 has a function of connecting and conducting the shielding plates, so that the potentials of the shielding structures in the socket assembly 200 are balanced. In this case, the upper shielding plate 222, the lower shielding plate 223, and the spacer plate 224 further form a structure of the foregoing connecting piece, to implement an electrical conduction function between shielding structures of the connecting bases 220.
In an embodiment, as shown in
For the data line 101 connected to the signal terminal 121, two data lines 101 may be both connected to one signal terminal 121 and each data line 101 is correspondingly connected to one conductive pin 1211, to implement a differential signal transmission function. In some other embodiments, the data line 101 may also include two transmission lines (not shown in the figure). The two transmission lines are used to form a differential signal, and each transmission line is connected to one conductive pin 1211. This may also implement a differential signal transmission function from the data line 101 to the signal terminal 121.
For an embodiment, refer to

Refer to embodiments in
In this embodiment, a width D1 of the first section 1211a that is of the conductive pin 1211 and that is located outside the plug body 110 is set to be greater than a width D2 of the second section 1211b that is located inside the plug body 110. In this way, impedances of the first section 1211a and the second section 1211b match each other. It may be understood that, because the first section 1211a is exposed outside the plug body 110, a peripheral medium of the first section 1211a is air. The second section 1211b is accommodated in the plug body 110, and a peripheral medium of the second section 1211b is an insulation material such as plastic. If the impedances of the first section 1211a and the second section 1211b do not match, in a process in which a signal is transmitted between the first section 1211a and the second section 1211b, current return disturbance occurs, and a crosstalk problem occurs. Therefore, an outline size difference is set between the first section 1211a and the second section 1211b. This may prevent the crosstalk problem.
In an embodiment, a transition section 1211c is further disposed on the conductive pin 1211. The transition section 1211c is located between the first section 1211a and the second section 1211b. One side that is of the transition section 1211c and that is close to the first section 1211a has a relatively large width, and one side that is of the transition section 1211c and that is close to the second section 1211b has a relatively small width. In addition, an outline slope of the transition section 1211c is even, to implement smooth transition of the conductive pin 1211 between the first section 1211a and the second section 1211b. Therefore, when a signal is transmitted between the first section 1211a and the second section 1211b, a phenomenon of current return disturbance may be further reduced because of transition effect of the transition section 1211c, to avoid signal crosstalk.
The foregoing descriptions are merely specific embodiments of this application, but are not intended to limit the protection scope of this application. Any variation or replacement, for example, reducing or adding a mechanical part, and changing a shape of a mechanical part, readily figured out by a person skilled in the art within the technical scope disclosed in this application shall fall within the protection scope of this application. When no conflict occurs, embodiments of this application and the features in embodiments may be mutually combined. Therefore, the protection scope of this application shall be subject to a protection scope of the claims.
