[0053] The beneficial effects of this disclosure are as follows: The connector in this disclosure, by placing the connecting terminals in the central island area, reduces the number of connecting terminals located on the edge of the connector, thus reducing the connector's size and contributing to the miniaturization and thinning of electronic devices. Simultaneously, the protective portion on the connecting terminals protects both ends of the central island, effectively preventing connector damage caused by misalignment during mating of the male and female connectors. Furthermore, by utilizing the central island area for the connecting terminals, the current-carrying area and path of the terminals can be made longer, allowing the terminals to be used for conducting high currents, ensuring more stable and reliable current conduction.

[0054] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0063] Figure 8 This is a schematic diagram of the structure of a connector male socket according to an exemplary embodiment. Detailed Implementation

[0064] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0065] In stacked system designs, different modules are typically connected electrically via connectors. With the continuous development of electronic equipment technology, the functional requirements for electronic devices are becoming increasingly diverse. To improve the stability and reliability of electrical connections, it is necessary to maximize the conductive current of the connectors to meet the needs of different application scenarios. The applicant, through extensive research, has discovered that... Figures 1-2 As shown, the connection terminal 10' is usually located on the housing of the connector, that is, the outer area of ​​the area where the central island 21' is located. In order to conduct a large current using the connector, for example, at the battery and charging interface, it is necessary to use the connector to achieve a large current conduction. This usually requires more connection terminals 10' or an increase in the size of the connection terminals 10', which will inevitably increase the size of the connector. Therefore, it is difficult to achieve a compact and miniaturized design of electronic devices by using the connectors in the related technology.

[0066] Meanwhile, because connectors typically have a large number of 10' terminals, production line misalignment can easily lead to processing errors, causing the connector to malfunction. Alternatively, improper alignment or force during the mating of the male and female connectors can cause damage and deformation, rendering the connector unusable. In related technologies, the material of the middle island 21' is relatively soft, making misalignment during mating highly susceptible to damage. Therefore, to prevent connector damage, it is usually necessary to separately install first armor plates 22' at both ends of the middle island 21' to protect its edges. While this solution meets the requirements for high current and protection against breakage, the added first armor plates 22' make it difficult to reduce the connector length, failing to meet the miniaturization design requirements of electronic devices, and also increasing the connector's manufacturing cost.

[0067] To address the aforementioned technical problems, this disclosure provides a connection terminal, a connector, a connector assembly, and an electronic device. The connection terminal refers to the pins of the connector. The connector, for example, can be a BTB (Board-to-Board Connector), primarily used for electrical connections between different circuit boards to achieve signal, power, and data transmission. It provides stable and reliable electrical contact, ensures efficient communication between circuit boards, adapts to high-frequency signal transmission requirements, reduces electromagnetic interference, and thus helps simplify the internal circuit layout of devices and improve the space utilization of compact electronic products. The connector assembly generally includes a male connector and a female connector that mate to form an electrical connection. The male and female connectors are mated together, with their corresponding pins connected to form current and electrical signal conduction. The electronic device can be, for example, a mobile terminal, a laptop, a tablet, a smartwatch, an electronic bracelet, etc., and this disclosure does not impose excessive limitations on these devices.

[0068] According to an exemplary embodiment, this disclosure provides a connection terminal. The connector has two forms: a male connector and a female connector (hereinafter referred to as male and female). The male and female connectors are connected by a plug-in connection to achieve electrical connection. The male connector is typically a plug-type design, with structures such as pins or conductors to facilitate insertion into the female connector. The female connector is typically a socket-type design, with recessed holes or contact points to facilitate mating with the male connector to achieve electrical connection. Figures 3-4 As shown, the connection terminal in this embodiment is a female terminal. In order to meet the requirements of conductivity, the connection terminal can be made of conductive materials such as metal and alloy.

[0069] This embodiment uses Figure 3 and Figure 4Taking a female connector as an example, the structure of the connector terminal will be described. The connector terminal includes a first fixing part 11 and a protective part 12. The fixing part 11 can be used to fix and connect to a structure such as a circuit board, thereby creating current conduction between the circuit board and the connector terminal. The protective part 12 is connected to the first fixing part 11. The protective part 12 has an arc-shaped housing, which forms a receiving area for accommodating the part to be protected (i.e., the part to be protected). Figure 7 The island 21 shown provides some protection for the protected part. When the connection terminal is installed... Figure 7 When the central island 21 shown is placed on the central island 21, the four corner positions of the central island 21 can be protected. The first armor is formed directly on the central island 21 by the protection part 12, without the need to set up an additional first armor. This is beneficial to reduce the size of the connector, reduce production costs and manufacturing difficulty, and also to avoid damage to the corner positions of the central island 21 due to misalignment when the male and female connectors are plugged in, thereby improving the connection reliability and extending the service life of the connector.

[0070] The connecting terminal also includes at least one first connecting arm 13. The number of first connecting arms 13 can be one or two, depending on the function of the connecting terminal. When there are two first connecting arms 13, the two first connecting arms 13 are arranged in parallel. In some embodiments, when the connecting terminal in this embodiment is used as a current terminal of the female connector, it can be used as a grounding terminal for grounding or as a power terminal for connecting to a power source. When the connecting terminal is used as a power terminal, two first connecting arms 13 can be provided; when the connecting terminal is used as a grounding terminal, one first connecting arm 13 can be provided. Thus, when both the grounding terminal and the power terminal are installed on the central island 21, one first connecting arm of the grounding terminal can extend between the two first connecting arms 13 of the power terminal, thereby making the structure more compact. In some possible embodiments, the power terminal can also be provided with one first connecting arm 13, and the grounding terminal can be provided with two first connecting arms 13. In other possible embodiments, both the power terminal and the grounding terminal are provided with two parallel first connecting arms 13. When both the power terminal and the grounding terminal are installed on the central island 21, the two sets of first connecting arms 13 are installed in a plug-in state, and the four first connecting arms 13 are parallel to each other.

[0071] The first connecting arm 13 extends outward from the protective part 12, so as to Figure 3 Taking the orientation shown as an example, the first connecting arm 13 extends horizontally in a direction away from the protective part 12. The first connecting arm 13 includes a first contact area 131, which is located at the end of the first connecting arm 13 away from the protective part 12. The first contact area 131 is used for contact connection with other structures to achieve electrical connection. When the connecting terminal is installed... Figure 7When the first connecting arm 13 extends along the length of the island 21 shown in the diagram, it has a longer extension dimension, which is beneficial to achieve a longer current conduction path, thereby enabling it to carry a larger current, reaching a current carrying capacity of more than 20A. This is about 5A higher than the existing maximum current carrying capacity of 15A, which can better meet the current carrying capacity requirements of large-capacity battery modules for connectors.

[0072] As the charging power of electronic devices increases, battery capacity also increases accordingly. Connectors used between the battery and the motherboard need to handle larger currents to cope with high-power transmission scenarios. Connectors are equipped with signal terminals for transmitting signals and current terminals for transmitting current, both located on the edge of the connector housing. To ensure the connector can handle high-power current transmission, related technologies have four high-current terminals on the male and female connectors. Compared to signal terminals, these high-current terminals are wider to handle the large current, which increases the connector's size. In this embodiment, a connection terminal adapted to the structure of the central island is provided. This not only protects the central island but also reduces the space occupied by the high-current terminals, decreasing the number of connection terminals on the connector edge and thus reducing the connector's size. Furthermore, the connection terminal includes a connecting arm extending outward from the protective portion, with the end of the connecting arm furthest from the protective portion designated as a first contact area for contact connection. This increases the path for high current to pass through the connection terminal, facilitating high current flow and improving the stability and reliability of the electrical connection.

[0073] In some embodiments, the protective portion 12 is bent relative to the first fixing portion 11, and the first connecting arm 13 and the first fixing portion 11 are located on different planes to form a staggered space between the first connecting arm 13 and the first fixing portion 11 to form the protective portion 12 to accommodate the end of the island 21. In one example, the protective portion 12 is bent once relative to the first fixing portion 11, the protective portion 12 is located on a first plane, and the first fixing portion 11 is located on a second plane. There is a preset angle between the first plane and the second plane. The preset angle can be, for example, a common tilt angle such as 30°, 45°, 60°, or 90°. Of course, the embodiments of this disclosure do not impose too many restrictions on the specific angle of the preset angle. Those skilled in the art can design and adjust it according to the structure and size of the island 21.

[0074] In another example, the protective portion 12 is bent relative to the first fixing portion 11 at least twice. The protective portion 12 is located on a first plane, and the first fixing portion 11 is located on a second plane, with the first and second planes parallel to each other. The bending of the protective portion 12 relative to the first fixing portion 11 allows the first connecting arm 13 and the first fixing portion 11 to be located on different planes, avoiding mutual interference. It can also, for example... Figure 7 The structures such as the central island 21 shown in the diagram form a buffer and serve as a cover and protection, while also extending the conductive path of high current, thereby increasing the conductive path, which is conducive to the flow of high current and improves the electrical connection effect.

[0075] In some embodiments, the connection terminal includes a power terminal and a ground terminal. The power terminal is connected to a power source, and the ground terminal is connected to a grounding point, allowing current to flow within the connection terminal to achieve grounding. One of the power terminal and the ground terminal includes a first connecting arm 13, and the other includes two parallel first connecting arms 13. In one example, the power terminal includes two parallel first connecting arms 13, and the ground terminal includes one first connecting arm 13. In another example, the ground terminal includes two parallel first connecting arms 13, and the power terminal includes one first connecting arm 13.

[0076] Of course, it is understandable that in the actual design and production process, the power terminal and the ground terminal can be configured such that one of them includes a first connecting arm 13, and the other includes two parallel first connecting arms 13; or both the power terminal and the ground terminal can be configured to include a first connecting arm 13; or both the power terminal and the ground terminal can be configured to include two parallel first connecting arms 13. The embodiments disclosed herein do not impose too many restrictions on this, as long as the connecting terminals can play the required connection role and the power terminal and the ground terminal do not interfere with each other.

[0077] In one example, the connection terminal serves as a power terminal, which includes two parallel first connecting arms 13, and a first fastening portion 132 includes a first protrusion 1321. For example... Figure 3 As shown, the first protrusion 1321 protrudes from the first connecting arm 13 along its length. The first protrusion 1321 is curved, bending towards the plane of the first fixing part 11, so as to improve the bonding force when the first connecting arm 13 is connected to other structures (such as the housing or island of the connector) by means of snap-fit ​​or increasing the contact area. Since a grounding terminal is inserted between the two first connecting arms 13, in order to avoid the grounding terminal from contacting the power supply electronics, the first fastening part 132 is provided at the end of the first connecting arm 13, thereby effectively preventing the first fastening part 132 from accidentally contacting the grounding terminal.

[0078] In one example, the connecting terminal includes a first connecting arm 13, and the first fastening portion 132 includes at least one second protrusion 1322. For example... Figure 4 As shown, the second protrusion 1322 protrudes from the first connecting arm 13 along its width direction. The second protrusion 1322 is curved and bends towards the plane where the first fixing part 11 is located to improve the bonding force of the first connecting arm 13. In this embodiment, there are two second protrusions 1322, which extend in opposite directions along the width direction of the first connecting arm 13. It is understood that the number of second protrusions 1322 can also be other. The extension directions of different second protrusions 1322 can be the same or different, and the spacing between two adjacent second protrusions 1322 can be equal or unequal. This embodiment does not impose too many restrictions on the specific arrangement of the second protrusions 1322, and those skilled in the art can choose according to actual needs.

[0079] In one example, the connecting terminal includes two parallel first connecting arms 13, and the connecting terminal also includes a second fastening portion 133. For example... Figure 3 As shown, the second fastening part 133 is disposed on the protection part 12, and the second fastening part 133 is located between two parallel first connecting arms 13. The second fastening part 133 is in a bent state to improve the bonding force between the connecting terminal and other structures, thereby improving the connection stability and reliability.

[0080] In one example, the connection terminal includes a first connecting arm 13, and a first contact area 131 of the first connecting arm 13 includes an arcuate area 134. For example... Figure 4 As shown, the arc-shaped region 134 is located at the end of the first connecting arm 13 away from the first fixing part 11 and the protective part 12, and the diameter of the arc-shaped region 134 is greater than the width of the first connecting arm 13, so as to increase the contact area and improve the contact effect.

[0081] In one example, the first connecting arm 13 is provided with a first fastening part 132, and the first fastening part 132 also includes a third protrusion (not shown in the figure). The third protrusion may be a curved protrusion similar in structure to the first protrusion 1321 and the second protrusion 1322. The third protrusion is curved toward the plane where the first fixing part 11 is located, and the first fastening part 132 is provided around the first contact area 131 to increase the contact area of ​​the first contact area 131 with other structures and improve the connection reliability of the first contact area 131.

[0082] In some embodiments, the first fixing part 11 is provided with a through hole 111, which is used to enhance the stability of the connecting terminal. For example, when the connecting terminal is injection molded together with other structures, the volume of the plastic material of the connector embedded in the through hole 111 can improve the bonding stability between the connecting terminal and the connector body; for another example, a snap-fit ​​structure that mates with the through hole 111 can be provided on other structures to improve connection stability; for yet another example, fasteners such as screws can be provided to secure the connection through the through hole 111. This disclosure does not impose excessive limitations on these embodiments, and those skilled in the art can make settings according to actual needs. In addition, the first fixing part 11 penetrates the connector base, thereby exposing the side of the base that is connected to the circuit board, and the first fixing part 11 is soldered to the circuit board.

[0083] In some embodiments, the first fixing portion 11 includes a first conducting region 112 and a first fixing region 113. For example... Figures 3-4 As shown, the area of ​​the first conductive region 112 is larger than the area of ​​the first fixed region 113, thus exposing a larger area on the surface of the connector housing. This increases the current carrying capacity of the connection terminal by increasing the current-carrying area. A through-hole 111 is located at the junction of the first conductive region 112 and the first fixed region 113 to simultaneously fix both regions, improving structural stability. It is understood that the through-hole 111 can also be located only within the first conductive region 112 or the first fixed region 113; this embodiment does not impose excessive limitations on this.

[0084] According to an exemplary embodiment, this disclosure provides a connection terminal. For example... Figures 5-6 As shown, the connection terminal in this embodiment is a male terminal. The structure of the male terminal is similar to that of the female terminal described in the above embodiments, and the male terminal is used to cooperate with the female terminal described in the above embodiments to achieve electrical connection.

[0085] like Figures 5-6 As shown, the connecting terminal includes a second fixing part 14, a connecting part 15, and at least one second connecting arm 16. The number of second connecting arms 16 can be one or two. The specific number of second connecting arms 16 can be set according to the corresponding number of first connecting arms 13 in the above embodiment, and will not be elaborated further here. The connecting part 15 is connected to the second fixing part 14. The connecting part 15 includes a connected first part 151 and a second part 152. The first part 151 is connected to the second fixing part 14, and at least one second connecting arm 16 extends outward from the second part 152 to... Figure 5 Taking the orientation shown as an example, the second connecting arm 16 extends in a direction away from the second part 152 along the horizontal direction.

[0086] The second connecting arm 16 includes a second contact area 161. The second contact area 161 is used for contact connection with other structures to achieve electrical connection. The second contact area 161 is located at the end of the second connecting arm 16 away from the connecting portion 15, and the second contact area 161 is provided with contact protrusions 162. The contact protrusions 162 are used to make point contact with the first contact area 131 of the first connecting arm 13. By reducing the contact area, contact wear is reduced while achieving electrical connection, thereby improving the stability and reliability of the electrical connection.

[0087] In some embodiments, the second portion 152 is bent relative to the first portion 151 so that the first portion 151 and the second portion 152 are located in different planes. In the above embodiments, the female terminal includes a first fixing portion 11 and a protective portion 12 bent relative to the first fixing portion 11. The bending causes the first connecting arm 13 and the first fixing portion 11 to be located in different planes. Figure 7 The central island 21 shown is avoided and protected. Therefore, since the connection terminal in this embodiment is a male terminal that mates with the female terminal, the first part 151 and the second part 152 in this embodiment also need to be bent accordingly to facilitate connection with the female terminal described in the above embodiment, avoid mutual interference between the male terminal and the female terminal, and improve the stability and reliability of the electrical connection.

[0088] The second part 152 can be bent relative to the first part 151 once or multiple times. The specific number of bends, bending direction and other factors need to be coordinated with the female terminal in the above embodiment. This disclosure does not impose too many restrictions on this, and those skilled in the art can make adjustments according to actual needs.

[0089] In some embodiments, the area of ​​the first portion 151 is larger than the area of ​​the second fixing portion 14. Since the area of ​​the first portion 151 is larger than the area of ​​the second fixing portion 14, the connection terminal can have a larger current-carrying area, thereby improving the current carrying capacity of the connection terminal, improving the electrical connection effect, and also being suitable for connection scenarios with higher current requirements.

[0090] In some embodiments, the connection terminal includes a power terminal and a ground terminal. Similar to the female connector terminal in the above embodiments, the connection terminal in this embodiment, as a male connector terminal, also includes a power terminal and a ground terminal corresponding to the female connector terminal, and the power terminal of the male connector corresponds to the power terminal of the female connector, and the ground terminal of the male connector corresponds to the ground terminal of the female connector. One of the power terminal and the ground terminal of the male connector terminal includes a second connecting arm 16, and the other includes two parallel second connecting arms 16. The second connecting arms 16 are used to cooperate with the first connecting arm 13 to achieve electrical connection when the male connector terminal and the female connector terminal are connected.

[0091] In this embodiment, both the power terminal and the ground terminal can be provided with one second connecting arm 16, or one of them can be provided with one second connecting arm 16 and the other with two second connecting arms 16, or both can be provided with two second connecting arms 16. This disclosure does not impose excessive limitations on the second connecting arms 16. Those skilled in the art can adjust the number and shape of the second connecting arms 16 according to actual needs to achieve the effect of electrical connection while avoiding interference between the power terminal and the ground terminal.

[0092] According to an exemplary embodiment, this disclosure provides a connector. The connector of this embodiment is a female connector, which includes the connecting terminals described in the above embodiments. Figure 7 As shown, the connector includes a first base 20, which has a central island 21. The central island 21 serves to position the connector during insertion between the male and female connectors, preventing misalignment and damage. A gap 22 exists between the first base 20 and the central island 21, which accommodates the male connector during connection. The central island 21 has connection terminals; that is, in the above embodiment, the power supply terminal and grounding terminal of the female connector are both located on the central island 21, thereby transmitting the power supply current through the connection terminals.

[0093] The connection terminals include a first connection terminal 101 and a second connection terminal 102. Both the first connection terminal 101 and the second connection terminal 102 extend along the length direction of the central island 21 and are arranged opposite to each other along the length direction of the central island 21. The connecting arms of the first connection terminal 101 and the second connection terminal 102 are spaced apart along the width direction of the central island 21. One of the first connection terminal 101 and the second connection terminal 102 is a power terminal, electrically connected to a power source, and the other is a ground terminal, electrically connected to the grounding terminal of the circuit board or a grounding structure such as the middle frame or rear shell.

[0094] In some embodiments, the connecting terminal includes a first fixing part 11 and a protective part 12. The protective part 12 is connected to the first fixing part 11 and includes a receiving area (not shown in the figure). The protective part 12 covers the end of the central island 21 and has an arc-shaped shell forming the receiving area. The end of the central island 21 is located within the receiving area; that is, the protective part 12 avoids the central island 21. The arc-shaped shell of the protective part 12 covers the four apex positions of the central island 21, forming a first armor. This armor provides a certain degree of protection for the central island 21, improving connection reliability and extending the connector's service life. Furthermore, by forming the protective part 12 of the connecting terminal without the need for a separate first armor, the connector size can be reduced, allowing for more space for overall stacking. It also reduces production costs and manufacturing difficulty, facilitating cost and time savings in mass production. Meanwhile, the connector in this embodiment can also be additionally provided with a second armor plate 23. The second armor plate 23 is disposed on at least a portion of the first base 20 to protect the first base 20. The second armor plate 23 and the first armor plate together provide protection for the connector, which helps to improve the safety of the connector connection and extend the service life of the connector. The connection terminal also includes at least one first connecting arm 13, which extends outward from the protective part 12. The first connecting arm 13 includes a first contact area 131, which is disposed at the end of the first connecting arm 13 away from the protective part 12. The first contact area 131 is used to contact other structures to achieve electrical connection.

[0095] Compared to related technologies, in the connector of this embodiment, the connecting terminal is provided with a first connecting arm, thereby increasing the current flow of the connecting terminal and improving the stability and reliability of the electrical connection. Furthermore, placing the connecting terminal in the central island 21 can improve space utilization, not only carrying a larger current, but also allowing for more connecting terminals to be provided without increasing the overall size of the connector. For example, in addition to providing connecting terminals for electrical connections, signal connecting terminals 40 for signal connections can also be provided on the connector, thereby enabling the connector to meet different usage requirements and be applied to different usage scenarios.

[0096] In some embodiments, the first connecting terminal 101 is provided with two parallel first connecting arms 13, and the second connecting terminal 102 is provided with one first connecting arm 13. The first connecting arm 13 of the second connecting terminal 102 extends between the two first connecting arms 13 of the first connecting terminal 101, and the first connecting terminal 101 and the second connecting terminal 102 enclose each other, forming a protective island 21. Of course, it is understood that those skilled in the art can adjust the number and shape of the first connecting arms 13 of the first connecting terminal 101 and the second connecting terminal 102 according to actual needs, and the embodiments disclosed herein do not impose excessive limitations in this regard.

[0097] In some embodiments, the connecting terminals are connected to the first base 20 by injection molding. For example... Figures 3-4 As shown, the first connecting arm 13 is provided with a first fastening part 132. The first fastening part 132 is disposed around the first contact area 131 and extends into the interior of the central island 21, thereby improving the bonding force of the injection molding connection between the connecting terminal and the first base 20 and improving the connection stability.

[0098] In one example, the first fastening part 132 includes a first protrusion 1321 that protrudes from the first connecting arm 13 along the length direction of the first connecting arm 13 of the first connecting terminal 101 and bends toward the central island 21 to improve the bonding force between the first connecting arm 13 and the central island 21.

[0099] In one example, the first fastening part 132 further includes a second protrusion 1322, which protrudes from the first connecting arm 13 along the width direction of the first connecting arm 13 of the second connecting terminal 102 and bends toward the central island 21 to increase the bonding force between the first connecting arm 13 and the central island 21.

[0100] In one example, the first connection terminal 101 also includes a second fastening portion 133. For example... Figures 3-4 As shown, the second fastening part 133 is disposed on the protective part 12 of the first connecting terminal 101. The second fastening part 133 is located between the two parallel first connecting arms 13 of the first connecting terminal 101. The second fastening part 133 bends toward the central island 21 and extends into the central island 21, thereby further increasing the bonding force between the first connecting arm 13 and the central island 21 and improving the connection stability.

[0101] In some embodiments, the first fixing part 11 is provided with a through hole 111, and a portion of the structure of the first seat 20 is embedded in the through hole 111. The through hole 111 is used to increase the contact area between the first fixing part 11 and the first seat 20 to improve the connection effect. The through hole 111 can be formed by injection molding or obtained by processing after the first fixing part 11 is formed. A portion of the structure of the first seat 20 can be directly formed in the through hole 111 or formed separately and then snapped into the through hole 111. The embodiments of this disclosure do not impose too many restrictions on this, and those skilled in the art can set it according to actual needs.

[0102] In some embodiments, the first fixing portion 11 includes a first conducting region 112 and a first fixing region 113. For example... Figures 3-4As shown, the area of ​​the first conductive region 112 is larger than the area of ​​the first fixed region 113, thereby increasing the current carrying capacity of the connection terminal by increasing the current-carrying area. A through-hole 111 is disposed at the junction of the first conductive region 112 and the first fixed region 113 to simultaneously fix both regions, improving structural stability. Of course, it is understood that the through-hole 111 can also be disposed only within the first conductive region 112 or the first fixed region 113; this embodiment does not impose excessive limitations on this.

[0103] In one example, a first conductive region 112 is exposed on a first side of the first base 20, and a first fixing region 113 passes through the first base 20 and is exposed on a second side of the first base 20. The first base 20 avoids the first conductive region 112 so that the first conductive region 112 is exposed on the first side of the first base 20, thereby avoiding interference with heat dissipation of the connection terminals. The first side is the side of the first base 20 where the central island 21 is located, and the second side is opposite to it. The first side of the first base 20 is used for electrical connection with the connector, while the second side can be fixed to other structures and / or electrically connected to other structures. For example, the second side of the first base 20 can be connected to a circuit board (not shown), and the portion of the first fixing region 113 that passes through the first base 20 and is exposed on the second side of the first base 20 is soldered to the circuit board.

[0104] According to an exemplary embodiment, this disclosure provides a connector. The connector of this embodiment is a male connector for mating with the female connector described in the above embodiments to achieve electrical connection, and the connector of this embodiment includes the connection terminals described in the above embodiments. Figure 8 As shown, the connector in this embodiment includes a second base 30, which has a receiving area 31. When the male connector of this embodiment is connected to the female connector in the above embodiment, the receiving area 31 of the second base 30 is used to accommodate and avoid the central island 21 and the connecting terminal of the female connector.

[0105] The connector in this embodiment further includes connection terminals disposed on the bottom surface of the receiving area, and the connection terminals are used to transmit power supply current. The connection terminals include a third connection terminal 103 and a fourth connection terminal 104, one of which is a power terminal and the other is a ground terminal. Both the third connection terminal 103 and the fourth connection terminal 104 extend along the length direction of the receiving area 31, are disposed opposite to each other along the length direction of the receiving area 31, and are spaced apart along the width direction of the receiving area 31.

[0106] In some embodiments, the connecting terminal includes a second fixing portion 14 and a connecting portion 15. The connecting portion 15 is connected to the second fixing portion 14 and includes a first portion 151 and a second portion 152 connected together. The first portion 151 is connected to the second fixing portion 14. The connecting terminal also includes at least one second connecting arm 16, which extends outward from the second portion 152. The second connecting arm 16 includes a second contact area 161, which is located at the end of the second connecting arm 16 away from the connecting portion 15. The second contact area 161 is provided with contact protrusions 162, which are used to make point contact with the first contact area 131 of the first connecting arm 13. By reducing the contact area, contact wear is reduced while achieving electrical connection, thereby improving the stability and reliability of the electrical connection.

[0107] In some embodiments, the connecting terminal is connected to the second housing 30 by injection molding. For example... Figures 5-6 As shown, the first portion 151 is embedded in the second base 30, and the first portion 151 is exposed on the first side of the second base 30. The first portion 151 is used to fix with the second base 30 and to enable the connecting terminal to contact and connect with the connecting terminal of the connecting female. The second fixing portion 14 passes through the second base 30 and is exposed on the second side of the second base 30. The second fixing portion 14 is used to fix with the second base 30 and to connect with the circuit board disposed on the second side of the second base 30.

[0108] In one example, the third connecting terminal 103 is provided with two parallel second connecting arms 16, and the fourth connecting terminal 104 is provided with one second connecting arm 16. That is, the third connecting terminal 103 is provided corresponding to the first connecting terminal 101 in the above embodiment, and the fourth connecting terminal 104 is provided corresponding to the second connecting terminal 102 of the connecting female in the above embodiment. The second connecting arm 16 of the fourth connecting terminal 104 extends between the two second connecting arms 16 of the third connecting terminal 103.

[0109] According to an exemplary embodiment, this disclosure provides a connector assembly including a connector female as described above in the embodiments of this disclosure (such as...). Figure 7 As shown) as the female connector, and the male connector as described in the above embodiments of this disclosure (such as...) Figure 8 (As shown) serves as the male connector. The male and female connectors can be electrically connected to electronic devices such as circuit boards and cables, or they can be fixedly connected to other structures.
