[0001] Cross Reference to Related Applications

[0002] The present application claims priority to the Chinese patent application No. 202411115481.0, filed on August 14, 2024, and entitled “Connector, charging cable and electronic device”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the technical field of electrical connector design, and in particular to a connector, a charging cable and an electronic device. BACKGROUND

[0004] Users have increasingly high demands on the charging speed of electronic devices, and manufacturers have launched electronic devices with high-power charging capabilities to meet user demands. Based on the technical requirements of high current, the wire of the charging cable of the electronic device is relatively thick, and the welding point between the wire and the circuit board of the plug is relatively high. In order to prevent the welding point and the shielding shell on the periphery of the circuit board from short-circuiting, a window is usually opened on the shielding shell to avoid the welding point. Opening a window on the shielding shell will affect the electromagnetic shielding effect, thereby reducing the electromagnetic compatibility (EMC) of the electronic device. It should be noted that electromagnetic compatibility refers to the ability of a device or system to operate in its electromagnetic environment in accordance with requirements and not to produce intolerable electromagnetic interference to any device in its environment. SUMMARY

[0005] In a first aspect, an embodiment of the present application provides a connector. The connector provided by the embodiment of the present application comprises a terminal assembly and a circuit board. The terminal assembly comprises an insulating base and a plurality of terminals embedded in the insulating base. The circuit board comprises a first side and a second side facing away from each other, and the first side is provided with a cable pad. Each of the terminals is arranged at intervals along one side of the circuit board, and the soldering leg of each of the terminals is welded to the circuit board. The side of the terminal facing away from the circuit board is provided with a plug-in area. In the thickness direction of the connector, the center surface of the circuit board relative to the plug-in area is biased in the direction away from the first side.

[0006] In a second aspect, an embodiment of the present application provides a charging cable. The charging cable provided by the embodiment of the present application comprises a wire and any one of the connectors provided by the embodiments of the present application. One end of the wire is electrically connected to the cable pad.

[0007] In a third aspect, an electronic device is provided. The electronic device includes a device body and any of the charging cords provided in the embodiments of the present application. The device body is provided with a socket, and the connector is used to interface with the socket.

[0008] The above at least one technical solution adopted by the embodiments of the present application can achieve the following beneficial effects:

[0009] In the embodiments of the present application, the circuit board is offset in the thickness direction of the connector, with the center surface of the connector facing away from the first side surface. In this way, the first side surface of the circuit board provided with the cable pad has a larger spacing from the shielding shell provided at the outer periphery of the circuit board, so that it is not necessary to open a window on the shielding shell at a position opposite to the welding point of the cable pad. Thus, the electromagnetic shielding effect of the shielding shell can be improved, and the problem of being unable to simultaneously avoid the short circuit risk and ensure electromagnetic compatibility in the related art is solved.

DETAILED DESCRIPTION

[0021] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms “mounting”, “connection”, “connecting” should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0023] In addition, although the terms used in the present application are selected from the commonly known and used terms, some terms mentioned in the description of the present application can be selected by the applicant according to his or her judgment, and the detailed meanings of the terms are described in the relevant part of the description.

[0024] In addition, the present application is required to be understood not only by the actual terms used, but also by the meaning implied by each term.

[0025] The technical solutions provided by the embodiments of the present application are described in detail below with reference to the drawings.

[0026] The embodiments of the present application provide a connector. Referring to FIGS. 1-9, the embodiments of the present application provide a connector 10. The connector 10 comprises a terminal assembly 11 and a circuit board 12. Exemplarily, the connector 10 can be a connector of Universal Serial Bus (USB) Type-C form factor standard. For example, the connector 10 is a USB Type-C plug.

[0027] The terminal assembly 11 comprises an insulating base 111 and a plurality of terminals 112 embedded in the insulating base 111. Exemplarily, the insulating base 111 can be made by injection molding, wherein the insulating base 111 is provided with through holes for passing the terminals 112. Further, the terminals 112 can be passed through the insulating base 111 to make the terminal assembly 11. It should be noted that in the case that the terminal assembly 11 further comprises other components in addition to the insulating base 111 and the terminals 112, after the terminals 112 are passed through the insulating base 111, the other components can be further assembled to make the terminal assembly 11.

[0028] Referring to FIGS. 2 and 8, the circuit board 12 comprises a first side 121 and a second side 122 facing away from each other, and the first side 121 is provided with a cable pad 1211. Wherein, as the name implies, the cable pad 1211 can be used for welding with the wire 20, so that the wire 20 is electrically connected with the connector 10.

[0029] The terminals 112 are arranged along one side edge of the circuit board 12. Referring to FIG. 2 in detail, the terminals 112 are arranged along the left side edge of the circuit board 12. Further, the soldering legs of the terminals 112 are respectively welded with the circuit board 12. It should be noted that the first side 121 and the second side 122 of the circuit board 12 are respectively provided with terminal pads, so that the soldering legs of the terminals 112 are respectively welded with the circuit board 12.

[0030] Referring to FIG. 8 in detail, the side of the terminal 112 facing away from the circuit board 12 is provided with a plug-in area 112a. It should be noted that the plug-in area 112a is used for plug-in cooperation with other connectors matched with the connector 10, so that the two are electrically connected. Exemplarily, in the case that the connector 10 is a USB Type-C plug, the spring of the terminal on the upper layer of the USB Type-C plug is bent downward, the spring of the terminal on the lower layer of the USB Type-C plug is bent upward, and the plug-in area is formed between the upper and lower layer springs. In the case that the USB Type-C plug is inserted into the USB Type-C socket, the tongue of the Type-C socket is inserted into the plug-in area.

[0031] In the thickness direction of the connector 10, the circuit board 12 is offset from the center of the insertion area 112a in a direction away from the first side 121. More colloquially, taking the orientation shown in FIG. 8 as an example, in the vertical direction, the circuit board 12 is offset downward from the position of the center of the insertion area 112a. In other words, in the vertical direction, the circuit board 12 is not centrally disposed relative to the terminal assembly 11, but rather is offset downward from the center of the terminal assembly 11 in the vertical direction. In this way, the first side 121 of the circuit board 12, which is provided with the cable pads 1211, can be spaced farther apart from the shielding shell provided on the outer periphery of the circuit board 12, so that without having to open a window in the shielding shell, the solder joints on the cable pads 1211 are also less likely to short circuit with the shielding shell. Furthermore, the electromagnetic shielding effect of the shielding shell can be improved by eliminating the avoidance window for the avoidance solder joint on the shielding shell.

[0032] In this way, in the embodiments of the present application, because in the thickness direction of the connector 10, the circuit board 12 is offset from the center of the insertion area 112a in a direction away from the first side 121, the first side 121 of the circuit board 12, which is provided with the cable pads 1211, can be spaced farther apart from the shielding shell provided on the outer periphery of the circuit board 12, so that without having to open a window in the shielding shell, the solder joints on the cable pads 1211 are also less likely to short circuit with the shielding shell. Thus, the electromagnetic shielding effect of the shielding shell can be improved.

[0033] It should be noted that in the related art, the spacing between the pin of a voltage bus (VBUS) terminal and the pin of an adjacent signal terminal is small, so that in the event of an accidental shift of the terminal, the pin of the VBUS terminal can short circuit with the pin of the adjacent signal terminal, and the connector can be damaged during charging. To solve this technical problem, the connector 10 provided in the foregoing is further improved in the embodiments of the present application, and the further improved connector 10 is described below.

[0034] In some embodiments, the plurality of terminals 112 includes two VBUS terminals and a plurality of signal terminals. The VBUS terminals are used to supply power during charging. The plurality of signal terminals are each disposed between the two VBUS terminals, and the spacing between the pin of any VBUS terminal and the pin of an adjacent signal terminal is greater than the spacing between the pins of any two adjacent signal terminals. In this way, by increasing the distance between the pin of the VBUS terminal and the pin of the adjacent signal terminal, accidental short circuit between the pin of the VBUS terminal and the pin of the adjacent signal terminal due to a shift of the terminal 112 can be avoided. Thus, the problem of damage to the connector 10 due to short circuit between the pin of the VBUS terminal and the pin of the adjacent signal terminal during charging can be improved.

[0035] To facilitate the better implementation of the scheme provided by the embodiments of the present application for those skilled in the art, the following provides a more detailed connector scheme for those skilled in the art to refer to.

[0036] Referring to FIG. 2, in some embodiments, the two VBUS terminals are respectively a first VBUS terminal 1121 and a second VBUS terminal 1122. The plurality of signal terminals include a data minus (DM) terminal 1131, a data positive (DP) terminal 1132, a configuration channel (CC) terminal 1133, and a voltage connection (VCONN) terminal 1134. It should be noted that the DM terminal 1131 can also be represented as a D- terminal, and the DP terminal 1132 can also be represented as a D+ terminal.

[0037] Further, the first leg 1121a of the first VBUS terminal 1121, the leg 1131a of the DM terminal 1131, the leg 1132a of the DP terminal 1132, the leg 1133a of the CC terminal 1133, and the first leg 1122a of the second VBUS terminal 1122 are sequentially soldered to the first side 121. In combination with FIG. 5, the second leg 1121b of the first VBUS terminal 1121, the leg 1134a of the VCONN terminal 1134, and the second leg of the second VBUS terminal 1122 are sequentially soldered to the second side 122.

[0038] It should be noted that in the related art, the DM terminal, the DP terminal, the CC terminal, and the VCONN terminal are all double-leg structures. That is, the DM terminal, the DP terminal, the CC terminal, and the VCONN terminal all have two legs, one of which is soldered to the first side of the circuit board, and the other of which is soldered to the second side of the circuit board. In this way, four soldering positions need to be reserved between the first VBUS terminal and the second terminal to respectively solder the legs of the DM terminal, the DP terminal, the CC terminal, and the VCONN terminal.

[0039] However, by adopting the scheme provided by the embodiments of the present application, the DM terminal 1131, the DP terminal 1132, the CC terminal 1133, and the VCONN terminal 1134 are all single-leg structures. Among them, the leg 1131a of the DM terminal 1131, the leg 1132a of the DP terminal 1132, and the leg 1133a of the CC terminal 1133 are soldered to the first side 121 of the circuit board 12, and the leg 1134a of the VCONN terminal 1134 is soldered to the second side 122 of the circuit board 12.

[0040] Thus, between the first VBUS terminal 1121 and the second VBUS terminal 1122, only 3 soldering positions can be reserved on the first side 121 of the circuit board 12, and 1 soldering position can be reserved on the second side 122 of the circuit board 12. In this way, compared with the scheme in the related art which requires reserving 4 soldering positions, the pitch between the pin of the VBUS terminal and the pin of the adjacent signal terminal can be increased without changing the pitch of the pins of the signal terminals. Thus, the pin of the VBUS terminal is less likely to be short-circuited with the pin of the adjacent signal terminal.

[0041] With reference to FIGS. 2 and 3, in some embodiments, the pin 1131a of the DM terminal 1131, the pin 1132a of the DP terminal 1132, and the pin 1133a of the CC terminal 1133 are respectively bent relative to the body portion of each terminal in a direction away from the pin of the second VBUS terminal 1122. In combination with FIGS. 6 and 7, the pin 1134a of the VCONN terminal 1134 is bent relative to the body portion 1134b of the VCONN terminal 1134 in a direction away from the second pin 1121b of the first VBUS terminal 1121. In this way, the body portion of each of the VCONN terminal 1134, the DM terminal 1131, the DP terminal 1132, and the CC terminal 1133 can be arranged in sequence and spaced apart between the body portion 1121c of the first VBUS terminal 1121 and the body portion of the second VBUS terminal 1122.

[0042] In some embodiments, the pitch between the pin of each VBUS terminal and the pin of the adjacent signal terminal is equal. In combination with FIG. 3, in other words, the pitch between the first pin 1121a of the first VBUS terminal 1121 and the pin 1131a of the DM terminal 1131 is a first distance, the pitch between the first pin 1122a of the second VBUS terminal 1122 and the pin 1133a of the CC terminal 1133 is a second distance, and the pitch between the second pin 1121b of the first VBUS terminal 1121 and the pin 1134a of the VCONN terminal 1134 is a third distance. The first distance, the second distance, and the third distance are equal. Of course, in other embodiments, the first distance and the second distance can be equal, and the third distance can be greater than or equal to the first distance. Alternatively, in other embodiments, only the first distance, the second distance, and the third distance are required to be greater than the pitch of the pin of the adjacent signal terminal.

[0043] In some embodiments, the pins of the signal terminals soldered to the first side 121 are equally spaced. In other words, in combination with FIG. 3, the pin 1131a of the DM terminal 1131, the pin 1132a of the DP terminal 1132, and the pin 1133a of the CC terminal 1133 are equally spaced.

[0044] With reference to FIG. 2 and FIG. 3, in some embodiments, the plurality of terminals 112 further comprises two Ground (GND) terminals embedded in the insulating base 111. Two VBUS terminals are arranged between the two GND terminals, and the pins of the VBUS terminals are adjacent to the pins of the GND terminals respectively. Exemplarily, the two GND terminals are a first GND terminal 1141 and a second GND terminal 1142 respectively. The two VBUS terminals are arranged between the first GND terminal 1141 and the second GND terminal 1142.

[0045] With reference to FIG. 2, in some embodiments, the conductive terminals 11 further comprise a clasp 115 embedded in the insulating base 111. The clasp 115 is used to provide appropriate plugging resistance during plugging.

[0046] With reference to FIG. 4 and FIG. 8, in some embodiments, the outer periphery of the rear end of the insulating base 111 is provided with a recess 1111. The connector 10 further comprises an adhesive 13, which is bonded to the circuit board 12 and fills the recess 1111. Exemplarily, the adhesive 13 can be formed after the terminals 112 are welded to the circuit board 12, and the adhesive is then solidified to form the adhesive 13. In the embodiments of the present application, by providing the recess 1111, the bonding effect of the adhesive 13 is improved to prevent the terminal assembly 11 and the circuit board 12 from being separated accidentally.

[0047] With reference to FIG. 4, in some embodiments, the side of the recess 1111 away from the insulating base 111 is provided with a protrusion 1112 protruding relative to the bottom of the recess 1111. In this way, the adhesive 13 can hook the protrusion 1112 to better prevent the terminal assembly 11 and the circuit board 12 from being separated accidentally.

[0048] The embodiments of the present application provide a charging cable. With reference to FIG. 1 and FIG. 2, the charging cable 1 provided by the embodiments of the present application comprises a wire 20 and any one of the connectors 10 provided by the embodiments of the present application. One end of the wire 20 is electrically connected to the cable pad 1211.

[0049] Further, in some embodiments, the connector 10 further comprises a first shielding shell 14. Referring to Fig. 8, the first shielding shell 14 is sleeved outside the terminal assembly 11. The charging cord 1 further comprises a second shielding shell 30, the second shielding shell 30 is connected with the rear end of the first shielding shell 14, and the second shielding shell 30 is sleeved outside the circuit board 12. In combination with Fig. 9, the distance between the first side surface 121 and the inner wall of the second shielding shell 30 facing the first side surface 121 is greater than the distance between the second side surface 122 and the inner wall of the second shielding shell 30 facing the second side surface 122. In this way, by increasing the distance between the first side surface 121 of the circuit board 12 and the second shielding shell 30, the soldering points of the cable pads 1211 arranged on the first side surface 121 can be prevented from short-circuiting with the second shielding shell 30.

[0050] Referring to Fig. 2, in some embodiments, the connector 10 further comprises an inner protective sleeve 41, a cable protective sleeve 42 and an outer protective sleeve 43. The inner protective sleeve 41 is sleeved outside the second shielding shell 30, the cable protective sleeve 42 is connected with the inner protective sleeve 41 and sleeved outside the end of the wire 20 welded with the cable pads 1211. Further, the outer protective sleeve 43 is sleeved outside the inner protective sleeve 41.
