Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a connector terminal and a connector. Background Technology

[0002] Connectors, also known domestically as plugs, sockets, and connectors, generally refer to electrical connectors, which are devices that connect two active devices to transmit current or signals. Connectors are a component that electronic engineers frequently encounter. Their function is very simple: to bridge gaps in a circuit or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function.

[0003] In the field of electrical connections, many electrical circuits require terminal connections. Currently, most connections are achieved by interlocking plug-in terminals and cylindrical terminals, especially in high-current, large-diameter wire harnesses. For example, in the rapidly developing new energy vehicles, the charging guns and charging sockets for charging batteries use an interlocking structure of plug-in and cylindrical terminals. However, most existing cylindrical terminals are formed by machining copper alloys, which is costly. Therefore, a new technology is needed to solve these problems. Utility Model Content

[0049] Please refer to Figures 1 to 17 As shown, it illustrates the specific structures of two embodiments of this utility model, wherein, Figures 1 to 13 The specific structure of Embodiment 1 is shown. Figures 14 to 17 The specific structure of Embodiment 2 is shown.

[0050] like Figures 1 to 13 As shown in Embodiment 1, a connector includes a male connector 10 and a female connector 20 that are plugged into each other.

The female connector 20 includes a base 30, a back plug 40, a core 50, a plurality of connector terminals 60, and a molding part 70.

[0051] like Figures 1 to 13As shown in Embodiment 1, the core 50 has a plurality of terminal holes 51 arranged in a matrix; a plurality of connector terminals 60 are respectively inserted into the plurality of terminal holes 51, and the insertion portion 63 of the connector terminal 60 extends out of one end of the core 50, and the conductive portion 62 of the connector terminal 60 extends out of the other end of the core 50; the rear plug 40 has a plurality of positioning holes 41 arranged in a matrix; the vertical portion 622 of the conductive portion 62 of the connector terminal 60 is respectively inserted into the corresponding positioning hole 41 and extends out of the lower end of the rear plug 40; the core 50 and the connector terminals 60 are inserted into the base 30 from back to front as a whole. The insertion portion 63 of the connector terminal 60 extends into the receiving hole of the base 30. The rear plug 40 is inserted from bottom to top onto the vertical portion 622 of the conductive portion 62 of the connector terminal 60. One end of the vertical portion 622 of the conductive portion 62 of the connector terminal 60 extends out of the lower end of the base 30. The molding portion 70 is formed between the connector terminal 60, the rear plug 40, and the base 30 by molding. The front end of the base 30 is inserted into the insertion cavity 11. One end of the male terminal 12 is inserted into the insertion cavity 64 of the insertion portion 63 of the connector terminal 60.

[0052] like Figures 9 to 11 As shown in Embodiment 1, the connector terminal 60 includes a cylindrical terminal body 61. The terminal body 61 is formed into a cylindrical structure by stamping, rolling and joining a sheet-like terminal substrate. This enables the terminal to be stamped, which is more precise and less expensive than existing machining methods.

[0053] like Figures 9 to 11 As shown in Embodiment 1, the conductive part 62 and the plug-in part 63 are respectively connected to both ends of the terminal body 61 in the axial direction. The conductive part 62 includes a horizontal part 621 and a vertical part 622. The horizontal part 621 extends along the axial direction of the terminal body 61. One end of the horizontal part 621 is connected to the terminal body 61, and the vertical part 622 is connected to the other end of the horizontal part 621 and extends inward.

[0054] like Figures 9 to 11As shown in Embodiment 1, one end of the horizontal portion 621 is integrally connected to the terminal body 61, and the vertical portion 622 is integrally folded inward from the other end of the horizontal portion 621. The vertical portion 622 is perpendicular to the axis of the terminal body 61. Specifically, the vertical portion 622 includes a connecting plate portion 6221 and a columnar portion 6222. The connecting plate portion 6221 is integrally folded inward from the other end of the horizontal portion 621. The columnar portion 6222 is integrally connected to the end of the connecting plate portion 6221 away from the horizontal portion 621. The columnar portion 6222 is formed into a columnar structure by stamping, rolling, and butt jointing. Both the connecting plate portion 6221 and the columnar portion 6222 are perpendicular to the axis of the terminal body 61. One end of the columnar portion 6222 passes through the positioning hole 41 and extends out of the lower end of the base 30.

[0055] like Figures 9 to 11 As shown in Embodiment 1, the two opposite sides of the terminal body 61 near the transverse portion 621 are integrally folded outward to form limiting protrusions 611. The limiting protrusions 611 are restricted by the rear sidewall of the core 50 to limit the depth of the connector terminal 60 inserted into the core 50, so as to avoid the phenomenon of excessive insertion.

[0056] like Figures 9 to 11 As shown in Embodiment 1, on the outer peripheral sidewall of the terminal body 61 near the transverse portion 621, two pairs of protrusions 612 are integrally formed outward on each side, so that the connector terminal 60 and the terminal hole 51 of the core 50 fit more tightly and securely.

[0057] like Figures 9 to 11 As shown in Embodiment 1, the plug-in portion 63 includes a plurality of elastic arms 631, each elastic arm 631 extending along the axial direction of the terminal body 61, one end of each elastic arm 631 being integrally connected to the end of the terminal body 61 away from the conductive portion 62, and the other end of each elastic arm 631 being a contact end. The plurality of elastic arms 631 are arranged at uniform intervals around the axis of the terminal body 61 in the circumferential direction, and the plurality of elastic arms 631 together form the plug-in cavity 64.

[0058] like Figures 14 to 17The diagram shows the specific structure of the connector terminal 60 provided in Embodiment 2. The basic structure of the connector terminal 60 in Embodiment 2 is the same as that in Embodiment 1, except that: in Embodiment 2, one end of the horizontal portion 621 is integrally connected to the terminal body 61, and the vertical portion 622 is welded to the other end of the horizontal portion 621 and extends inward. The vertical portion 622 is perpendicular to the axis of the terminal body 61. A welding portion 6211 is provided at the other end of the horizontal portion 621, and the vertical portion 622 is a copper pillar. One end of the copper pillar is welded to the welding portion 6211, and the welding portion 6211 has a welding hole 6212. One end of the copper pillar is welded into the welding hole 6212. Thus, during manufacturing, it can be stamped and formed first. The connector terminal body with the horizontal portion 621 is produced, and then the copper wire is cut to obtain a copper pillar of the required length. Then, one end of the copper pillar is welded into the welding hole 6212. This allows for flexible selection according to the actual required length of the vertical portion 622, which is more conducive to meeting processing requirements. In the second embodiment, the limiting protrusion 611 and the protrusion 612 are not provided. Instead, limiting walls 65 are integrally extended outward and backward on both sides of the end of the terminal body 61 near the horizontal portion 621. The limiting walls 65 are integrally connected to the horizontal portion 621. In addition, when using the connector terminal 60 provided in the second embodiment, the base 30, rear plug 40, core 50, molding portion 70, etc. of the female connector 20 are all adjusted accordingly.

[0059] In summary, the key design feature of this utility model is that it forms a cylindrical structure by stamping and rolling the terminal body through a sheet-like terminal substrate. This enables the terminal to be processed by stamping, which is more precise and less expensive than existing machining methods.

[0060] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
