[0013] One ends of the plurality of second signal terminals are aligned with the second reference line, and a second preset distance is formed between one end of the second detection terminal and the second reference line in the second direction.
[0014] In one possible implementation manner, a second preset distance between one end of the first detection terminal and the first reference line in the second direction is 0.3 mm-0.5 mm.
[0015] In one possible implementation manner, when the external plug is inserted into the connecting member, the contact length between the second detection terminal and the connecting terminal of the plug is 0.11 mm-0.81 mm.

The system of the electronic device obtains the signal, and controls the circuit timing to disconnect the electrical connection between the electrical connector and the external plug to close the transmission of the electrical signal. In this way, by setting the length of one end of the first detection terminal to be shorter than the length of one end of the first signal terminal, at the moment when the first detection terminal abuts against the connection terminal of the external electronic device or is separated from the connection terminal of the external electronic device, there is a larger contact area between the plurality of first signal terminals and the connection terminal of the external plug, which is conducive to the fact that arc is not easily generated when the external plug is plugged in and out, thereby improving the safety of the electrical connector.

[0033] The present embodiment provides an electrical connector, which is used to electrically connect to an external plug; illustratively, the electrical connector can be a female end of Type-C, and the plug is a male end, and the transmission of electrical signals between the male end and the female end is achieved by inserting the male end into the female end.
[0034] It can be understood that the existing female end is provided with a terminal row, and the terminal row includes multiple terminals, and the multiple terminals are aligned with one end facing the outside. Correspondingly, a terminal row is also provided on the male end, and the number of terminal rows on the male end is the same as that of the terminal rows on the female end and they correspond one to one. When the male end is inserted into the female end, the multiple terminals on the female end simultaneously abut against the multiple terminals on the male end, and each terminal on the female end abuts against a corresponding terminal of the male end.
[0035] The following describes in detail the various embodiments of the present application in conjunction with the accompanying drawings.
[0036] For ease of explanation, Figure 1A three-dimensional coordinate system is added, the direction of the X-axis is the first direction, that is, the setting direction of the multiple first signal terminals 121, the direction of the Y-axis is the second direction, that is, the extension direction of the first signal terminals 121, and the direction of the Z-axis is the third direction, that is, the setting direction of the first terminal group and the second terminal group 13, wherein the first direction, the second direction and the third direction are perpendicular to each other.
[0037] Please also read Figure 1 and Figure 2 The present embodiment provides an electrical connector 10 for electrically connecting to an external plug. The electrical connector 10 includes a connector 11 and a first terminal group 12. A first reference line 111 is provided on one side of the connector 11. The first reference line 111 extends along a first direction. The first terminal group 12 includes a plurality of first signal terminals 121 and a first detection terminal 122. The plurality of first signal terminals 121 and the first detection terminal 122 are spaced apart along the first direction and connected to one side of the connector 11. One end of the plurality of first signal terminals 121 is aligned with the first reference line 111. A first preset distance A is formed between one end of the first detection terminal 122 and the first reference line 111 in the second direction. Each first signal terminal 121 extends along the second direction, and the first detection terminal 122 extends along the second direction.
[0038] In the above-mentioned electrical connector 10, when the external plug is inserted into the connecting member 11, the plurality of first signal terminals 121 first abut against the connecting terminals connected to the external plug and form a larger contact area, until the first detection terminal 122 is connected to the connecting terminal of the external plug, the system of the electronic device will obtain the signal, and control the circuit timing to achieve electrical connection between the plurality of first signal terminals 121 and the connecting terminals of the external plug, so as to achieve the transmission of electrical signals and reduce the risk of arc generation. When the external plug is pulled out of the connecting member 11, the first detection terminal 122 is first separated from the connecting terminal of the external plug. At this time, the plurality of first signal terminals 12 1 also has a large contact area with the connection terminal of the external plug, the system of the electronic device obtains the signal, and controls the circuit timing to disconnect the electrical connection between the electrical connector 10 and the external plug to close the transmission of the electrical signal; in this way, by setting the length of one end of the first detection terminal 122 to be shorter than the length of one end of the first signal terminal 121, when the first detection terminal 122 is abutted against the connection terminal of the external electronic device or is detached from the connection terminal, a large contact area is formed between the plurality of first signal terminals 121 and the connection terminal of the external plug, which is conducive to preventing arcs from being easily generated when the external plug is plugged in and out, thereby improving the safety of the electrical connector 10.
[0039] In this embodiment, the number of the first detecting terminals 122 can be multiple.
[0040] See also Figure 2In some embodiments, a first preset distance A formed between one end of the first detection terminal 122 and the first reference line 111 in the second direction is 0.3 mm-0.5 mm; specifically, the first preset distance A is 0.4 mm.
[0041] In this way, when the first preset distance is greater than 0.5mm, that is, the shortened distance of one end of the first detection terminal 122 is too large, so that when the external plug is inserted into the connector 11, the connecting terminal of the external plug cannot contact the first detection terminal 122, and the circuit detection protection function cannot be realized. When the first preset distance A is less than 0.3mm, that is, the shortened length of one end of the first detection terminal 122 is too small, after the system of the electronic device receives the disconnection signal between the first detection terminal 122 and the connecting terminal of the external plug, the time for the multiple first signal terminals 121 to disconnect the electrical connection with the connecting terminals of the external plug through circuit timing control is shorter, resulting in that the multiple first signal terminals 121 and the connecting terminal of the external plug are still prone to arcing at the moment of plugging and unplugging, thereby reducing the arc extinguishing effect. When the first preset distance A is 0.3mm-0.5mm, the arc extinguishing effect can be improved on the basis of ensuring the stable contact between the first detection terminal 122 and the connecting terminal of the external plug.
[0042] In some embodiments, when the external plug is inserted into the connector 11 , the contact length between the first detection terminal 122 and the connecting terminal of the plug is 0.11 mm-0.81 mm.
[0043] In this way, when the contact length is too small, poor contact is likely to occur due to the influence of processing tolerances. When the contact length is too long, the overall length of the electrical connector 10 is too long, occupying the installation space, which is not conducive to the miniaturized structural design of electronic equipment. When the contact length is between 0.11mm-0.81mm, the contact stability between the first detection terminal 122 and the connecting terminal of the plug is improved without increasing the overall volume of the electrical connector 10.
[0044] In some embodiments, the cross-section of one end of the first signal terminal 121 is set as an arc surface, and the cross-section of one end of the first detection terminal 122 is set as an arc surface; so that the connecting terminal of the plug is guided by the arc surface to slide to abut against the side walls of the first signal terminal 121 and the first detection terminal 122.
[0045] See also Figure 3In some embodiments, a second reference line 112 is provided on the other side of the connector 11, and the second reference line 112 extends along the first direction. The electrical connector 10 further includes a second terminal group 13, and the second terminal group 13 includes a plurality of second signal terminals 131 and a second detection terminal 132. The plurality of second signal terminals 131 are spaced apart along the first direction and connected to the other side of the connector 11. The second detection terminal 132 and the plurality of signal terminals are spaced apart along the first direction and connected to the other side of the connector 11. One end of the plurality of second signal terminals 131 is aligned with the second reference line 112, and a second preset distance B is formed between one end of the second detection terminal 132 and the second reference line 112 in the second direction. Each second signal terminal 131 extends along the second direction, and the second detection terminal 132 extends along the second direction.
[0046] In this way, by setting a plurality of second signal terminals 131 and second detection terminals 132 on the other side of the connector 11, a double-sided plug-in terminal structure is formed, so that the external plug can achieve electrical connection whether it is plugged in the forward or reverse direction, thereby improving user convenience. At the same time, the double-sided plug-in terminal structure can form two groups of identical terminal structures, so as to improve the stability of the electrical connection.
[0047] In this embodiment, the number of the second detecting terminals 132 can be multiple.
[0048] See also Figure 3 In some embodiments, a second preset distance B formed between one end of the second detection terminal 132 and the second reference line 112 in the second direction is 0.3 mm-0.5 mm; the specific second preset distance B is 0.4 mm.
[0049] In this way, when the second preset distance B is greater than 0.5mm, that is, the shortened distance of one end of the second detection terminal 132 is too large, so that when the external plug is inserted into the connector 11, the connecting terminal of the external plug cannot contact the second detection terminal 132, and the circuit detection protection function cannot be realized. When the second preset distance B is less than 0.3mm, that is, the shortened length of one end of the second detection terminal 132 is too small, after the system of the electronic device receives the disconnection signal between the second detection terminal 132 and the connecting terminal of the external plug, the time for the multiple second signal terminals 131 to disconnect the electrical connection with the connecting terminals of the external plug through circuit timing control is shorter, resulting in that the multiple second signal terminals 131 and the connecting terminal of the external plug are still prone to arcing at the moment of plugging and unplugging, thereby reducing the arc extinguishing effect. When the second preset distance B is 0.3mm-0.5mm, the arc extinguishing effect can be improved on the basis of ensuring the stable contact between the second detection terminal 132 and the connecting terminal of the external plug.
[0050] In some embodiments, when the external plug is inserted into the connector 11 , the contact length between the second detection terminal 132 and the connecting terminal of the plug is 0.11 mm-0.81 mm.
[0051] In this way, when the contact length is too small, poor contact is likely to occur due to the influence of processing tolerances. When the contact length is too long, the overall length of the electrical connector 10 is too long, occupying the installation space, which is not conducive to the miniaturized structural design of electronic equipment. When the contact length is between 0.11mm-0.81mm, the contact stability between the second detection terminal 132 and the connecting terminal of the plug is improved without increasing the overall volume of the electrical connector 10.
[0052] In some embodiments, the cross-section of one end of the second signal terminal 131 is set as an arc surface, and the cross-section of one end of the second detection terminal 132 is set as an arc surface; so that the connecting terminal of the plug is guided by the arc surface to slide to abut against the side walls of the second signal terminal 131 and the second detection terminal 132.
[0053] See also Figure 1 In some embodiments, the connector 11 includes a connector 113 and a tongue plate 115, the connector 113 is provided with a slot 114, an external plug is inserted into the slot 114, the tongue plate 115 is received in the slot 114, and one end of the tongue plate 115 in the second direction is connected to the connector 113, and the tongue plate 115 is respectively connected to the first terminal group 12 and the second terminal group 13 on opposite sides in the third direction, that is, the first terminal group 12 and the second terminal group 13 are spaced apart in the third direction.
[0054] In this way, by providing a slot 114 on the connector 113, the tongue plate 115 can be accommodated and protected, and when the external plug is guided to be inserted into the slot 114, the connecting terminal of the plug can be in contact with the first terminal group 12 and the second terminal, thereby improving the stability of the plugging. At the same time, the slot wall of the slot 114 can also damp and fix the plug to prevent the plug from loosening due to external force and causing poor contact.
[0055] The working principle of the above-mentioned electrical connector 10 is roughly as follows:
[0056] When the external plug is inserted into the slot 114, the first signal terminals 121 and the second signal terminals 131 on the tongue plate 115 first contact with the connection terminals of the plug, and then the first detection terminals 122 and the second detection terminals 132 on the tongue plate 115 contact with the connection terminals of the plug. At the moment when the first detection terminals 122 and the second detection terminals 132 contact with the connection terminals of the plug, the first signal terminals 121 and the second signal terminals 131 first contact with the connection terminals of the plug stably and form a sufficient contact length. At the same time, the system of the electronic device obtains the signal and controls the circuit timing to realize electrical connection between the first signal terminals 121 and the second signal terminals 131 and the connection terminals of the plug, thereby reducing the risk of arc generation.
[0057] When the external plug is pulled out of the slot 114, the first detection terminal 122 and the second detection terminal 132 on the tongue plate 115 first come into contact with the connection terminal of the plug, and the multiple first signal terminals 121 and the multiple second signal terminals 131 on the tongue plate 115 first come into contact with the connection terminal of the plug. At the moment when the first detection terminal 122 and the second detection terminal 132 are disconnected from the connection terminal of the plug, the system of the electronic device obtains the signal and controls the circuit timing to disconnect the multiple first signal terminals 121 and the multiple second signal terminals 131 from the connection terminal of the plug, so that no current is generated when the multiple first signal terminals 121 and the multiple second signal terminals 131 are disconnected from the connection terminal of the plug, thereby reducing the risk of arc generation.
[0058] This embodiment provides an electronic device, which includes the above-mentioned electrical connector 10, so as to electronically improve the safety of the electronic device.
[0059] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
