Description

Technical Field

[0001] This application belongs to the field of electronic technology, specifically relating to a Type-C connector and an electronic device. Background Technology

[0002] The Type-C interface is a Universal Serial Bus (USB) interface that can be plugged in both forward and reverse directions. Due to its advantages such as high data transmission speed and support for high-current charging, it is now widely used in various electronic devices.

[0003] like Figures 1-4 As shown, current Type-C connectors typically include a metal middle plate 16, a first terminal group 11 and a second terminal group 12 disposed on both sides of the metal middle plate 16, and an insulator 15 that fixes the metal middle plate 16, the first terminal group 11, and the second terminal group 12 into one unit. The first terminal group 11 and the second terminal group 12 each include a pair of ground terminals 111 and a pair of power terminals 112.

[0004] In related technologies, to improve the charging power of electronic devices, the size of the power terminals is increased to enhance the current-carrying capacity of the Type-C interface. However, due to the small distance between the power terminals and the metal middle plate 16, as well as between the power terminals and adjacent terminals, the effect of increasing the thickness or width of the power terminals on improving the current-carrying capacity of the Type-C interface is very limited, making it difficult to effectively achieve high current flow.

[0054] The following is combined with Figures 5-17 This application describes a Type-C connector and an electronic device according to embodiments thereof.

[0055] This application provides a Type-C connector, such as Figures 5-7 As shown, a Type-C connector according to some embodiments of this application includes: a first terminal group 11 and a second terminal group 12, wherein the first terminal group 11 and the second terminal group 12 are arranged at intervals relative to each other and each includes a plurality of ground terminals 111 and a plurality of power terminals 112.

[0056] In this configuration, at least one of the first terminal group 11 and the second terminal group 12 has a plurality of grounding terminals 111 electrically connected through a first plate 13. The first plate 13 is disposed between the first terminal group 11 and the second terminal group 12 and is spaced apart from the power supply terminals 112.

[0057] And / or, a plurality of power terminals 112 of at least one of the first terminal group 11 and the second terminal group 12 are electrically connected via a second plate 14. The second plate 14 is disposed between the first terminal group 11 and the second terminal group 12 and spaced apart from the ground terminal 111.

[0058] Both the first plate 13 and the second plate 14 are conductors. The Type-C connector includes a connection body for electrical connection with a mating connector. This connection body includes a first terminal group 11, a second terminal group 12, and an insulator 15 that secures the first terminal group 11 and the second terminal group 12 together. The first plate 13 and the second plate 14 are also secured to the first terminal group 11 and the second terminal group 12 via the insulator 15. The portions of the first terminal group 11 and the second terminal group 12 used for electrical connection with the mating connector are exposed on opposite sides of the insulator 15.

[0059] Optionally, a plurality of grounding terminals 111 of the first terminal group 11 are located on the outermost side of the first terminal group 11, and a plurality of power terminals 112 are located between the plurality of grounding terminals 111. The plurality of grounding terminals 111 and the plurality of power terminals 112 of the first terminal group 11 are configured in a one-to-one correspondence with the plurality of grounding terminals 111 and the plurality of power terminals 112 of the second terminal group 12.

[0060] Furthermore, the first terminal group 11 and the second terminal group 12 also include a plurality of signal terminals disposed between the ground terminal 111 and the power supply terminal 112. The first plate 13 and the second plate 14 are also spaced apart from the plurality of signal terminals.

[0061] It should be noted that when the first board 13 and the second board 14 are provided at the same time, the first board 13 and the second board 14 are arranged at intervals to avoid short circuit between the power terminal 112 and the ground terminal 111 and to ensure the connection function of the Type-C connector.

[0062] Optionally, the number of grounding terminals 111 in the first terminal group 11 and the number of power supply terminals 112 in the first terminal group 11 and the second terminal group 12 are two.

[0063] In some embodiments of this application, at least one of the two grounding terminals 111 of the first terminal group 11 and the second terminal group 12 is electrically connected via the first plate 13. For example, as Figure 8 and Figure 9 As shown, the two grounding terminals 111 of the first terminal group 11 located on the upper side are electrically connected through the first plate 13. Figure 9 yes Figure 8The diagram shows a cross-sectional view of the two terminal groups and the first plate 13 at point BB. For example, the two grounding terminals 111 of the second terminal group 12 located on the lower side are electrically connected via the first plate 13. For example, as... Figure 10 As shown, the two grounding terminals 111 of the first terminal group 11 and the two grounding terminals 111 of the second terminal group 12 are both electrically connected through the first plate 13.

[0064] In some embodiments of this application, at least one of the first terminal group 11 and the second terminal group 12 has two power terminals 112 electrically connected via the second plate 14. For example, as Figure 11 As shown, the two power terminals 112 of the first terminal group 11 located on the upper side are electrically connected via the second plate 14. Similarly, the two power terminals 112 of the second terminal group 12 located on the lower side are electrically connected via the second plate 14. For example, as... Figure 12 As shown, the two power terminals 112 of the first terminal group 11 and the two power terminals 112 of the second terminal group 12 are both electrically connected through the second plate 14. The first plate 13 and the grounding terminal 111 can be integrally formed or welded together. The second plate 14 and the power terminals 112 can be integrally formed or welded together. The first plate 13 and the second plate 14 cover at least a portion of the first terminal group 11 and the second terminal group 12.

[0065] According to the embodiments of this application, the Type-C connector, by providing a first plate 13 and / or a second plate 14 between the first terminal group 11 and the second terminal group 12, connects multiple ground terminals 111 of at least one terminal group via the first plate 13, and / or connects multiple power terminals 112 of at least one terminal group via the second plate 14, thereby changing the separated state between multiple ground terminals 111 or multiple power terminals 112 in the same terminal group to a connected state, reducing the loop impedance between the power terminals 112 and the ground terminals 111, and thus improving the current carrying capacity of the Type-C connector. Furthermore, the first plate 13 and the second plate 14 are located between the first terminal group 11 and the second terminal group 12. When the first plate 13 and / or the second plate 14 are fixed together with the first terminal group 11 and the second terminal group 12 through an insulator 15, the structural strength of the Type-C connector tongue plate can be improved, extending its insertion and removal life. In addition, the first plate 13 is connected to the ground terminal 111, allowing the first plate 13 to shield signal interference between the first terminal group 11 and the second terminal group 12.

[0066] It should be noted that, as Figure 8As shown, in this embodiment, the width direction of the first terminal group 11 is consistent with the arrangement direction of the plurality of ground terminals 111 in the first terminal group 11, which is also the width direction of the Type-C connector. The width direction of the first terminal group 11 is consistent with the width direction of the second terminal group 12. The length direction of the first terminal group 11 and the length direction of the second terminal group 12 are consistent with the insertion direction of the Type-C connector. The thickness direction of the first terminal group 11 is orthogonal to its length and width directions. The thickness direction of the first terminal group 11 is consistent with the thickness direction of the second terminal group 12.

[0067] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the first plate 13 includes a first partition 131. A plurality of ground terminals 111 of the first terminal group 11 are electrically connected to the side of the first partition 131 near the first terminal group 11. And / or, a plurality of ground terminals 111 of the second terminal group 12 are electrically connected to the side of the first partition 131 near the second terminal group 12.

[0068] Specifically, a first partition 131 is spaced between a first terminal group 11 and a second terminal group 12, and has a first side and a second side facing away from each other. The first side faces the first terminal group 11, and the second side faces the second terminal group 12. Multiple grounding terminals 111 of the first terminal group 11 are electrically connected to the first side. (See [reference]). Figure 9 Alternatively, multiple ground terminals 111 of the second terminal group 12 are electrically connected to the second side. Alternatively, multiple ground terminals 111 of the first terminal group 11 are electrically connected to the first side, and multiple ground terminals 111 of the second terminal group 12 are electrically connected to the second side, see [reference]. Figure 10 .

[0069] like Figure 9 As shown, in some embodiments of this application, the grounding terminal 111 is electrically connected to the first partition 131 via an intermediate connector. Specifically, there are two grounding terminals 111, and the first plate 13 further includes two first connecting plates 132. One end of each of the two first connecting plates 132 is electrically connected to both ends of the first partition 131 in the width direction of the first terminal group 11, and the other end of each of the two first connecting plates 132 is electrically connected to the side of the two grounding terminals 111 of the first terminal group 11 or the second terminal group 12 that are close to each other.

[0070] Specifically, the first partition 131 has a first end and a second end in the width direction of the first terminal group 11. Two first connecting plates 132 are respectively connected to the first end and the second end of the first partition 131 and extend in a direction away from the side of the first partition 131 to form a U-shaped first plate 13. The side of the two grounding terminals 111 that are close to each other is the side of the two grounding terminals 111 that are close to the center line of the Type-C connector. The ends of the two first connecting plates 132 that are away from the first partition 131 are electrically connected to the side of the two grounding terminals 111 that are close to each other in the first terminal group 11 or the second terminal group 12, that is, any one of the first connecting plates 132 connects the first partition 131 and the corresponding grounding terminal 111 to form a Z-shaped folded plate structure. In this embodiment, the first plate 13 and the two grounding terminals 111 connected thereto can be integrally formed by a stamping process.

[0071] It should be noted that, Figure 9 The diagram shows the case where the two grounding terminals 111 of the first partition 131 and the first terminal group 11 are connected by two first connecting plates 132. The case where the first partition 131 and the second terminal group 12 are connected by two first connecting plates 132 is similar and will not be described again here.

[0072] like Figure 10 As shown, in some embodiments of this application, the grounding terminal 111 is directly connected to the first partition 131. Specifically, a plurality of grounding terminals 111 of the first terminal group 11 and / or the second terminal group 12 extend in their thickness direction to connect with the first partition 131. The grounding terminal 111 can be connected to the side of the first partition 131 by welding.

[0073] In one embodiment, two grounding terminals 111 of the first terminal group 11 or the second terminal group 12 extend in their thickness direction to connect with the first partition 131. The opposite sides of the two grounding terminals 111 of the first terminal group 11 or the second terminal group 12 are respectively flush with both sides of the first partition 131 in the width direction of the first terminal group 11. In this case, the two grounding terminals 111 and the first partition 131 can be integrally formed by a stamping process.

[0074] In another embodiment, such as Figure 10 As shown, the first partition 131 has a first snap-fit ​​portion 1311 on both sides of the first terminal group 11 in the width direction. The first snap-fit ​​portion 1311 is used to engage with the snap-fit ​​connector.

[0075] Specifically, the first snap-fit ​​portion 1311 is a protrusion extending outward from the first terminal group 11 in the width direction of the first partition 131. This protrusion is located near the front end of the first terminal group 11. The first partition 131 is fixed to the insulator 15, and the first snap-fit ​​portions 1311 on both sides are exposed to the insulator 15 for engagement with the mating connector. In this embodiment, the first partition 131 functions as the metal middle plate of a Type-C connector in related technologies.

[0076] In some embodiments of this application, such as Figures 11-13 As shown, the second plate 14 includes a second partition 141. A plurality of power terminals 112 of the first terminal group 11 are electrically connected to the side of the second partition 141 adjacent to the first terminal group 11. And / or, a plurality of power terminals 112 of the second terminal group 12 are electrically connected to the side of the second partition 141 adjacent to the second terminal group 12.

[0077] Specifically, the second partition 141 is spaced between the first terminal group 11 and the second terminal group 12, and has a third side and a fourth side facing away from each other. The third side faces the first terminal group 11, and the fourth side faces the second terminal group 12. Multiple power terminals 112 of the first terminal group 11 are electrically connected to the third side. (See [reference]). Figure 11 and Figure 12 Alternatively, a plurality of power terminals 112 of the second terminal group 12 are electrically connected to the fourth side. Alternatively, a plurality of power terminals 112 of the first terminal group 11 are electrically connected to the third side, and a plurality of power terminals 112 of the second terminal group 12 are electrically connected to the fourth side, see [reference]. Figure 13 .

[0078] like Figure 11 and Figure 12 As shown, in some embodiments of this application, the power terminal 112 is electrically connected to the second partition 141 via an intermediate connector. Specifically, there are two power terminals 112, and the second plate 14 further includes two second connecting plates 142. One end of each of the two second connecting plates 142 is electrically connected to both ends of the second partition 141 in the width direction of the first terminal group 11, and the other end of each of the two second connecting plates 142 is electrically connected to the side of the two power terminals 112 of the first terminal group 11 or the second terminal group 12 that are close to each other.

[0079] Specifically, the second partition 141 has a first end and a second end in the width direction of the first terminal group 11. Two second connecting plates 142 are respectively connected to the first end and the second end of the second partition 141 and extend in a direction away from the side of the second partition 141 to form a U-shaped second plate 14. The ends of the two second connecting plates 142 away from the second partition 141 are electrically connected to the sides of the two power terminals 112 of the first terminal group 11 or the second terminal group 12 that are close to each other. That is, any one of the second connecting plates 142 connects the second partition 141 and the corresponding power terminal 112 to form a Z-shaped folded plate structure. In this embodiment, the second plate 14 and the two power terminals 112 connected thereto can be integrally formed by a stamping process.

[0080] It should be noted that, Figure 9 The diagram shows the case where the two grounding terminals 111 of the first partition 131 and the first terminal group 11 are connected by two first connecting plates 132. The case where the first partition 131 and the second terminal group 12 are connected by two first connecting plates 132 is similar and will not be described again here.

[0081] In the above embodiments, a first plate 13 formed by a first connecting plate 132 and a first partition plate 131 connects two grounding terminals 111 to reduce the resistance of the grounding terminals 111; and / or, a second plate 14 formed by a second connecting plate 142 and a second partition plate 141 connects two power supply terminals 112 to reduce the resistance of the power supply terminals 112. This reduces the overall circuit resistance, according to the thermal energy formula: Q=I 2 RT, with the temperature rise of the Type-C connector and the time it takes for the full-load charging current to pass remaining constant, the loop resistance decreases, allowing the current to pass through to increase.

[0082] The dimensions of the first connecting plate 132 and the second connecting plate 142 in the thickness direction of the first terminal group 11 should ensure that the first terminal group 11 and the second terminal group 12 maintain a safe distance in the thickness direction, so as to ensure that the function of the Type-C connector is not affected, and also to provide a certain signal shielding effect for the first terminal group 11 and the second terminal group 12, thereby improving the high-frequency performance of the Type-C connector.

[0083] In this embodiment, the processing steps for integrally forming the first plate 13 and the two grounding terminals 111 include: unloading and loading material from the target plate to form the two grounding terminals 111 and a connecting portion connecting the two grounding terminals 111. The connecting portion is then stretched using a stretching process to create a step between the connecting portion and the two grounding terminals 111; the stretched portion is the first connecting plate 132. The processing steps for integrally forming the second plate 14 and the two power terminals 112 are similar to those for the first plate 13 and the two grounding terminals 111, and will not be described again here.

[0084] like Figure 13 As shown, in some embodiments of this application, the power terminal 112 is directly connected to the second partition 141. Specifically, a plurality of power terminals 112 of the first terminal group 11 and / or the second terminal group 12 extend in their thickness direction to connect with the second partition 141. The power terminals 112 can be connected to the side of the second partition 141 by soldering.

[0085] In one embodiment, two power terminals 112 of the first terminal group 11 or the second terminal group 12 extend in their thickness direction to connect with the first partition 131. The opposite sides of the two power terminals 112 of the first terminal group 11 or the second terminal group 12 are respectively flush with both sides of the second partition 141 in the width direction of the first terminal group 11. In this case, the two power terminals 112 and the second partition 141 can be integrally formed by a stamping process.

[0086] In another embodiment, such as Figure 12 and Figure 13 As shown, the Type-C connector provided in this application also includes two metal middle plates 16. The metal middle plates 16 are disposed between the first terminal group 11 and the second terminal group 12. The two metal middle plates 16 are located on both sides of the second partition 141 in the width direction of the first terminal group 11 and are spaced apart from the second partition 141. Each of the two metal middle plates 16 has a second latching portion 161 on its opposite side, which is used to engage with the latching position of the mating connector. The metal middle plates 16 are used to connect to the ground terminal of the interface circuit.

[0087] Specifically, the second latching portion 161 is a protrusion extending outward from the first terminal group 11 in the width direction of the metal middle plate 16. This protrusion is located on the metal middle plate 16 near the front end of the first terminal group 11. The metal middle plate 16 is fixed to the insulator 15, and the second latching portions 161 of both metal middle plates 16 are exposed to the insulator 15 for engagement with the mating connector. In this embodiment, the metal middle plate 16 can shield signal interference between the terminals on both sides, improve the structural strength of the Type-C connector tongue, and extend its insertion / removal life.

[0088] In some embodiments of this application, a plurality of grounding terminals 111 of one of the first terminal group 11 and the second terminal group 12 are electrically connected via a first plate 13. A plurality of power terminals 112 of one of the first terminal group 11 and the second terminal group 12 are electrically connected via a second plate 14. The first plate 13 and the second plate 14 are spaced apart along the length of the first terminal group 11, with the first plate 13 positioned closer to the front end of the first terminal group 11 than the second plate 14.

[0089] Specifically, when the Type-C connector provided in this application is provided with both a first plate 13 and a second plate 14, both the first plate 13 and the second plate 14 are connected to the first terminal group 11; or, both the first plate 13 and the second plate 14 are connected to the second terminal group 12; or, one of the first plate 13 and the second plate 14 is connected to the first terminal group 11 and the other is connected to the second terminal group 12.

[0090] In some embodiments of this application, such as Figure 7 As shown, both the grounding terminal 111 and the power terminal 112 have interconnected first segments 111a and second segments 111b. The first segment 111a is located closer to the front end of the first terminal group 11 than the second segment 111b. The width of the second segment 111b is greater than the width of the first segment 111a to improve the current-carrying capacity of the Type-C connector. A step is formed between the first segment 111a and the second segment 111b. Optionally, the first segment 111a is used for contact connection with a mating connector, and the second segment 111b is fixed within the insulator 15.

[0091] In this embodiment, the first segment 111a of the two grounding terminals 111 in the same terminal group has a first straight edge on the side where they are close to each other, and the first plate 13 is connected to the grounding terminal 111 through the first straight edge. The second segment 111b of the two power terminals 112 in the same terminal group has a second straight edge on the side where they are close to each other, and the second plate 14 is connected to the power terminal 112 through the second straight edge.

[0092] As a specific example, such as Figure 14 As shown, the first plate 13 connects to the straight edges of the two grounding terminals 111 of the first terminal group 11. This satisfies the process requirement of integrally forming the first plate 13 and the two grounding terminals 111 by stamping. Further, as... Figure 15 As shown, the second plate 14 is connected to the second ends of the two power terminals 112 of the first terminal group 11. The first plate 13 and the second plate 14 are spaced apart. While meeting the process requirements of stamping the first plate 13 and the two ground terminals 111 into one piece and stamping the second plate 14 and the two power terminals 112 into one piece, the current carrying capacity of the Type-C connector is further improved.

[0093] Optionally, a portion of the first segment 111a of the grounding terminal 111 and the power terminal 112 is exposed to the insulator 15 for contact connection with the mating connector. The second segment 111b of the grounding terminal 111 and the power terminal 112 is held within the insulator 15.

[0094] Optionally, either the first terminal group 11 or the second terminal group 12 is provided with two grounding terminals 111, which are the two outermost terminals in the width direction of the first terminal group 11. The inner sides of the first segment 111a and the second segment 111b of the two grounding terminals 111 are set as continuous straight edges, and the first segment 111a and the second segment 111b of the two grounding terminals 111 are connected through the first plate 13. In this way, the area of ​​the first plate 13 can be increased, and the loop impedance between the power supply terminal 112 and the grounding terminal 111 can be reduced to a greater extent.

[0095] like Figure 8 , Figure 9 , Figure 11 As shown, some embodiments of the Type-C connector provided in this application further include a snap-fit ​​member 17, which is a plate-shaped member extending in the thickness direction of the first terminal group 11. Snap-fit ​​members 17 are respectively provided on both sides of the first terminal group 11 in the width direction, and the snap-fit ​​members 17 are spaced apart from the first terminal group 11 and the second terminal group 12. A third snap-fit ​​portion 171 protrudes from the side of the snap-fit ​​member 17 opposite to the first terminal group 11, and the third snap-fit ​​portion 171 is used for engaging with the locking position of the mating connector.

[0096] The snap-fit ​​component 17 is integrally fixed to the first terminal group 11 and the second terminal group 12 via the insulator 15. The third snap-fit ​​portion 171 of the snap-fit ​​component 17 is exposed to the insulator 15 and is used for engaging with the locking position of the mating connector. The snap-fit ​​component 17 is a sheet metal part.

[0097] Specifically, such as Figure 16 As shown, the snap-fit ​​member 17 in this embodiment can be formed by a stamping and bending process. The snap-fit ​​member 17 has an inner side surface near the first terminal group 11 and an outer side surface away from the first terminal group 11. The outer side surface of the snap-fit ​​member 17 has a convex surface that protrudes in the direction away from the first terminal group 11, and the inner side surface of the snap-fit ​​member 17 has a concave surface facing the first terminal group 11 corresponding to the position of the third snap-fit ​​portion 171.

[0098] In related technologies, the contact surface between the metal middle plate and the mating connector is the stamped blank end face. The contact area between the metal middle plate and the mating connector for mutual mating and plugging depends on the thickness of the metal middle plate. In order to ensure that the metal middle plate does not contact the terminal, the thickness of the metal middle plate should not be too large.

[0099] In this embodiment, the dimension of the snap-fit ​​member 17 in the thickness direction of the first terminal group 11 is not limited by the material thickness and can be designed according to the stamping process and product space dimensions. The contact area for mating and plugging with the connector can be increased by increasing the dimension of the third snap-fit ​​part 171 in the thickness direction of the first terminal group 11. Under the same force, a smaller contact area results in greater wear, thereby improving the connector's mating life.

[0100] This embodiment eliminates the need for a metal middle plate for engaging with the mating connector between the first terminal group 11 and the second terminal group 12 by providing a snap-fit ​​connector 17. This frees up space for the first plate 13, allowing the two grounding terminals 111 of either the first terminal group 11 or the second terminal group 12 to be connected via the first plate 13. This embodiment also improves the insertion / removal performance of the Type-C connector while reducing the loop impedance between the power terminal 112 and the grounding terminal 111 to enhance current carrying capacity.

[0101] Furthermore, the snap-fit ​​connector 17 is provided with a plurality of first through holes 172, and a portion of the insulator 15 is located within the first through holes 172. Optionally, the snap-fit ​​connector 17 is provided with first through holes 172 at both ends along the length of the first terminal group 11. The insulator 15 is typically made of plastic and can be integrally molded with the first terminal group 11, the second terminal group 12, and the snap-fit ​​connector 17 by injection molding. During the injection molding process, the adhesive can flow into the first through holes 172, improving the bonding strength between the snap-fit ​​connector 17 and the insulator 15, thereby improving the insertion and removal performance of the Type-C connector.

[0102] Optionally, the first plate 13 and / or the second plate 14 are provided with a second through hole, which can improve the bonding strength between the first plate 13 and the second plate 14 and the insulator 15, thereby improving the plugging and unplugging performance of the Type-C connector.

[0103] This application also provides an electronic device including a housing and a Type-C connector. The Type-C connector is the Type-C connector described in any of the above embodiments. Figure 17 As shown, the Type-C connector also includes a housing 2, with a first terminal group 11 and a second terminal group 12 disposed within the housing 2, and the housing 2 connected to the housing of the electronic device. Specifically, the Type-C connector also includes an insulator 15, with the first terminal group 11 and the second terminal group 12 fixed together by the insulator 15, and the first terminal group 11 and the second terminal group 12 connected to the housing 2 by the insulator 15.
