The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0027] In the present disclosure, unless otherwise stated, directional words such as "upper", "lower", "top", and "bottom" are generally defined when the connection interface provided by the present disclosure is normally installed. Figure 4 and Figure 5 The thickness direction indicated by the arrow in the figure can be understood as the up and down direction, and "inside" and "outside" refer to the inside and outside of the corresponding component contour. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.
[0028] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.
[0029] In the related art, the connection interface includes a tongue, a groove is provided on the plastic of the tongue, and the terminal is located in the groove. There is a large gap between the terminal and the inner wall of the groove, which is easy for liquid to enter and corrode the metal terminal, affecting the corrosion resistance of the connection interface.
[0030] To solve the above problems, Figures 1 to 5 As shown, the present disclosure provides a connection interface, including a tongue 1, on which is provided an insulating body 11 and a terminal 12 located on the insulating body 11, wherein the insulating body 11 has an extension portion 111 overlapping a contact surface 120 of the terminal 12, and the projections of the extension portion 111 and the contact surface 120 of the terminal 12 in the thickness direction partially overlap.
[0031] In the present disclosure, the insulating body 11 may be plastic, and the terminal 12 may be electroplated with precious metals such as platinum, rhodium, and ruthenium, and the present disclosure does not limit this. As shown in FIG. 4 , the insulating body 11 partially extends to the contact surface 120, and the projections of the extension 111 and the contact surface 120 of the terminal 12 in the thickness direction partially overlap, as shown in FIG. Figure 5As shown, the width of the overlapping part is D, which can be specifically designed according to the width of the terminal 12. Here, with respect to the upper surface of the tongue 1, the "contact surface" refers to the top surface of the terminal 12, and the uncovered area can realize the electrical connection function of the connection interface. Specifically, the arrangement of the terminal 12 on the upper surface of the tongue 1 will be described in detail below. In the present disclosure, the projections of the extension portion 111 and the contact surface 120 in the thickness direction overlap, excluding the situation where the extension portion 111 completely covers the contact surface 120, thereby ensuring the electrical connection performance of the terminal 12. In addition, the connection interface can be a charging interface or a data transmission interface, for example, it can be any one of a Mini USB interface, a Micro USB interface, and a USBType-C interface.
[0032] In the connection interface provided by the present invention, the extension portion 111 overlaps the contact surface 120 of the terminal 12, which can close the gap between the terminal 12 and the insulating body 11, increase the contact area between the terminal 12 and the insulating body 11, and enable better bonding between the terminal 12 and the insulating body 11, thereby avoiding electrochemical corrosion of the terminal 12 caused by liquid ingress, and improving the overall corrosion resistance of the connection interface.
[0033] In this disclosure, Figure 4 As shown, the terminal 12 is embedded in the insulating body 11, and the insulating body 11 wraps the bottom surface and at least one side surface of the terminal 12. The insulating body 11 on both sides of the terminal 12 extends upward beyond the contact surface 120 and forms the above-mentioned extension portion 111. The terminal 12 is embedded in the insulating body 11, and the insulating body 11 is wrapped in the area except the contact surface 120, which can ensure the insulation of the non-contact surface of the terminal 12 and can ensure better combination of the terminal 12 and the insulating body 11. The extension portion 111 can be any appropriate structure overlapped on the contact surface 120, and the present disclosure does not make specific limitations. For example, the cross-section of the terminal 12 can be rectangular, the insulating body 11 wraps the two side surfaces and the bottom surface of the terminal 12, and the top surface is the contact surface 120.
[0034] like Figure 4 As shown, the extension portion 111 has an inclined surface extending obliquely downward and overlapping the contact surface 120. The design concept of the inclined surface can be introduced in conjunction with the isolation portion 13 below. In other embodiments, the cross section of the extension portion 111 can also be trapezoidal, arc-shaped, etc.
[0035] like Figure 1 and Figure 4 As shown, along the plugging and unplugging direction of the connection interface, at least one side of the terminal 12 is provided with an extension portion 111. Preferably, both sides of the terminal 12 are provided with extension portions 111, respectively, to ensure that there is no liquid accumulation on both sides, thereby avoiding electrochemical corrosion on both sides of the terminal.
[0036] In the related art, there is a groove between two adjacent terminals, and foreign matter can easily accumulate in the groove, causing a short circuit between the two terminals and affecting the function of the connection interface.
[0037] To solve this problem, Figure 5 As shown, in the connection interface provided by the present disclosure, the terminals 12 are arranged side by side in a spaced manner, and the insulating body 11 between two adjacent terminals 12 forms an isolation portion 13, and in the thickness direction, the isolation portion 13 protrudes from the contact surface 120 of the terminal 12. The provision of the isolation portion 13 can increase the short-circuit distance between two adjacent terminals 12, and can reduce the risk of terminal short circuit. In addition, the isolation portion 13 protrudes from the contact surface 120, and foreign matter is not easy to accumulate on it. Compared with the design of the groove, the protruding isolation portion 13 is more likely to expose foreign matter to the outside. In the process of using the connection interface, foreign matter can be easily removed without causing foreign matter accumulation.
[0038] Further, in the present disclosure, if Figure 5 As shown, the isolation portion 13 has a platform higher than the contact surface 120 and inclined surfaces on both sides of the platform, and the two inclined surfaces extend to the contact surfaces 120 of the terminals 12 on both sides of the isolation portion 13 respectively. The isolation portion 13 can be any appropriate structure protruding from the contact surface 120. In the embodiment designed to have a platform and two inclined surfaces, some foreign matter on the platform will enter the contact surface of one terminal along the inclined surface and will not accumulate on the isolation portion 13, thereby avoiding short circuiting of the two terminals 12. The width of the isolation portion 13 between two adjacent terminals 12 can be the same or different, and can be designed according to needs. Figure 3 As shown in FIG. 1 , the distances between the terminals 12 at the two ends and the adjacent terminals are larger, and the distances between the multiple terminals in the middle can be smaller and can be equal.
[0039] In this disclosure, Figure 2 and Figure 3 As shown, the two surfaces of the tongue piece 1 are respectively provided with an insulating body 11 and a terminal 12. The embodiment provided in the present disclosure is for the upper surface of the tongue piece 1, and the lower surface of the tongue piece 1 can adopt the same design concept, which will not be repeated here.
[0040] like Figure 1 and Figure 2 As shown, the connection interface further comprises a housing 2, and the tongue piece 1 is received in a receiving space of the housing 2, which can protect the tongue piece 1 and facilitate docking when the connection interface is plugged in or out.
[0041] In addition, in the present disclosure, the contact surface 120 of the terminal 12 is divided into a covering area provided with the insulating body 11 and a conductive area exposed to the outside, and the electroplating materials of the covering area and the conductive area can be different. Considering that the terminal portion in the covering area is not electrically connected, a lower-cost electroplating metal can be used, so that the electroplating specifications of the non-contact surface of the terminal 12 can be appropriately reduced to reduce product costs.
[0042] In the connection interface provided by the present disclosure, the structure of the tongue 1 is improved. On the one hand, the extension portion 111 overlaps the contact surface 120 of the terminal 12, which can close the gap between the terminal 12 and the insulating body 11. The insulating body 11 and the terminal 12 are better combined, which is conducive to reducing the electrochemical corrosion of the terminal 12 caused by the liquid entering the connection interface under normal use. On the second hand, the isolation portion 13 between two adjacent terminals 12 is arranged to protrude from the contact surface 120, which can increase the short-circuit distance between adjacent terminals 12, and by designing the isolation portion 13 as a structure with a vertex and two inclined surfaces, it can further avoid the accumulation of foreign matter in the isolation portion 13, thereby reducing the risk of short circuit between the two terminals 12, avoiding functional abnormalities in the connection interface, and improving the overall user experience. On the third hand, the contact surface 120 of the terminal 12 is partially covered by the insulating body 11, and the specifications of the electroplated metal used in the covering area can be appropriately reduced, that is, the electroplating specifications of the non-contact surface of the metal terminal can be appropriately reduced to reduce the cost of the product.
[0043] According to a second aspect of the present disclosure, a functional module is also provided, on which the connection interface introduced above is provided. The functional module may be a power module, an audio module, a communication module, etc.
[0044] According to a third aspect of the present disclosure, an electronic device is also provided, the electronic device is provided with the connection interface described above, the electronic device has all the beneficial effects of the connection interface, and no further description is given here. The electronic device can be a computer, a tablet, a speaker, a headset, or other devices, and can ensure the charging and data transmission functions of the electronic device, thereby improving the user experience.

The present disclosure is intended to cover any variations, uses or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art that are not disclosed in the present disclosure.

[0046] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
