Description

Technical Field

[0001] This utility model relates to the technical field of terminals and charging connectors for electronic devices, and particularly to a terminal and a charging connector using the same. Background Technology

[0002] In existing technologies, terminals for wireless contact charging, such as wireless contacts, are typically incorporated into the charging connector. These wireless contacts are connected to an internal PCB board, allowing the PCB board to control wireless charging via the wireless contacts. Generally, these terminals consist of positive and negative terminals mounted on an insulating base; that is, the positive and negative terminals and the insulating base are separate structures that need to be assembled to form a single unit. This assembly method presents problems such as cumbersome assembly, difficulty in precisely controlling assembly dimensions, and poor consistency. Furthermore, the terminals may lack sufficient strength, leading to charging or signal transmission interruptions during use. Damage to the terminals during production or assembly can increase defective products, reduce yield, waste raw materials, and result in low production efficiency. Utility Model Content

[0039] like Figure 1-15 As shown, this application provides a terminal and a charging connector using the same.

[0040] like Figures 1 to 5 As shown, the terminal of this utility model includes a contact portion 101, an inlay portion 102, a connecting portion 103, and a support portion 104. The contact portion 101 is used for contact connection with an external charging device, the inlay portion 102 is used for inlaying with an insulating base 10, the connecting portion 103 is used for connection with an external PCB board, and the support portion 104 is used to strengthen the connecting portion 103. The contact portion 101 and the connecting portion 103 are respectively connected to both ends of the inlay portion 102. The connecting portion 103 and the support portion 104 are connected by an arc-shaped fold 108. The connection point between the connecting portion 103 and the support portion 104 is bent, and the support portion 104 increases the strength of the connecting portion 103. A snap-fit ​​portion 105 is provided on the connecting portion 103.

[0041] like Figure 3As shown, a support portion 104 is formed by connecting the end of the connecting portion 103 via an arc-shaped fold-back portion 108. The support portion 104 and the connecting portion 103 are symmetrically arranged and have roughly the same shape. A first reinforcing portion 1043 is provided at the end of the support portion 104 away from the connecting portion 103, and a second reinforcing portion 1031 is provided at the end of the connecting portion 103 away from the support portion 104. The first reinforcing portion 1043 on the support portion 104 is bent through the arc-shaped fold-back portion 108 and then riveted to the second reinforcing portion 1031 on the connecting portion 103, forming a fastening connection between the support portion 104 and the connecting portion 103, thereby strengthening the connection portion 103. The end of the support portion 104 is connected to the material strip 109, which enables batch and automated production of terminals and facilitates the storage, use, and installation of terminals. In this embodiment, there is one set of the first reinforcing part 1043 and the second reinforcing part 1031, which are respectively disposed at the middle position of the end of the supporting part 104 and the connecting part 103; there may also be two or more sets of the first reinforcing part 1043 and the second reinforcing part 1031, which are disposed on both sides of the end of the supporting part 104 and the connecting part 103, and are evenly distributed.

[0042] like Figure 4 As shown, there is another embodiment of the fastening method between the support portion 104 and the connecting portion 103. A first circular hole 1044 is provided at the end of the support portion 104 away from the connecting portion 103, and a second circular hole 1032 is provided at the end of the connecting portion 103 away from the support portion 104. The first circular hole 1044 and the second circular hole 1032 correspond to each other. They are then injection molded into the interior of the insulating base 10. During injection molding, the plastic fills the first circular hole 1044 and the second circular hole 1032, thereby fastening the support portion 104 and the connecting portion 103 and strengthening the connecting portion 103. In this embodiment, there are two first circular holes 1044 and two circular holes 1032, but they can also be one or more, depending on the specific product structure.

[0043] The snap-fit ​​portion 105 is exposed outside the insulating base 10. The snap-fit ​​portion 105 includes symmetrically arranged first cards 1051 and second cards 1052. In this embodiment, two pairs of first cards 1051 and second cards 1052 are used. An upward-opening slot 106 is provided between the first cards 1051 and the second cards 1052. The combination design of the snap-fit ​​portion 105 and the slot 106 facilitates connection with the PCB board, enabling a snap-fit ​​connection with the PCB board. This eliminates the need for wiring and soldering between the terminals and the PCB board, eliminates the need for soldering positioning, and simplifies operation.

[0044] The support portion 104 and the latching portion 105 are connected by an arc-shaped fold 108, which increases the strength of the latching portion 105. A first support arm 1041 and a second support arm 1042 are provided. An upward-opening U-groove 107 is provided between the first support arm 1041 and the second support arm 1042. The U-groove 107 is connected to the latching portion 105 via the arc-shaped fold 8. The end of the support portion 104 is connected to the material belt 109, which makes the latching portion 105 stable and less prone to loosening, enabling uninterrupted charging or signal transmission and extending its service life.

[0045] The outer surface of the contact portion 101 is provided with a contact surface for contacting and connecting with an external charging base. The contact portion 101 has a planar irregular structure and the contact surface is planar, which can increase the contact area and make the contact more stable, so as to realize uninterrupted charging or signal transmission.

[0046] like Figures 6 to 12 As shown, embodiments of this application also provide a charging connector using the aforementioned terminals, including an insulating base 10. The terminal includes a contact portion 101 for contacting and connecting with an external charging device, an inlay portion 102 for inlay molding, a connecting portion 103 for connecting with an external PCB board, and a support portion 104 for reinforcing the strength of the connecting portion 103. The two ends of the inlay portion 102 are respectively connected to the contact portion 101 and the connecting portion 103, and the inlay portion 102 is inlaid and molded inside the insulating base 10. Parts of the contact portion 101 and the connecting portion 103 are exposed outside the insulating base 10, and a snap-fit ​​portion 105 is provided on the connecting portion 103. Both the contact portion 101 and the connecting portion 103 can be individually connected to external components, and can present different functions in different positions. By inlaying the inlay portion 102 inside the insulating base 10, the terminal and the insulating base 10 are integrally molded, thereby eliminating the need for assembly between the terminal and the insulating base 10, saving the assembly process and effectively solving the problem of insufficient dimensional control and poor consistency during the assembly of the terminal and the insulating base 10.

[0047] In this embodiment, two terminals are provided: a positive terminal 20 and a negative terminal 30. The positive terminal 20 and the negative terminal 30 are disposed opposite each other on the insulating base 10, and the positive terminal 20 and the negative terminal 30 adopt the same structural arrangement. This can be used for symmetrical installation and positioning, so as to more stably position the charging connector structure.

[0048] like Figure 5 As shown, in some embodiments, due to the product's structure, the terminal does not have a support portion 104. In this case, it is necessary to enhance the strength of the connecting portion 103 itself so that the terminal has sufficient strength to facilitate production and assembly.

[0049] In the above embodiments, the insulating base 10 is a plastic base, or other insulating materials may be used.

[0050] like Figures 13 to 15 As shown, in some embodiments, the charging connector 50 can be used at the distal end of each earphone stem 40. In this case, the slot 106 between the first card 1051 and the second card 1052 engages with the PCB board inside the earphone stem 40, and then the charging connector 50 can be attached to the distal end of the earphone stem 40 to couple charging and data signals to the earphone. The charging connector 50 can mate with a socket connector 60, and the contact portion 101 on the charging connector 50 is electrically connected to the metal spring on the socket connector 60, which can be mounted on the PCB.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.
