[0015] The present utility model will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in many different forms and should not be construed as limited to the embodiments described herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.
[0016] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "several" and "multiple" is two or more, unless otherwise specifically and clearly defined. In the present application, unless otherwise clearly specified and limited, terms such as "installed", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances. In the present application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath" and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.
[0017] Such as Figures 1 to 2As shown in the figure, the connector terminal of the embodiment of the present application includes a terminal body 1 and a round copper wire 2. At both ends of the terminal body 1, a first connection cylinder 3 and a second connection cylinder 4 are coaxially provided respectively. At the front end of the first connection cylinder 3, a first jack 31 for inserting a pin is provided, and a U-shaped slit 32 is provided on the side wall of the first connection cylinder 3. An elastic contact piece 5 is formed through the U-shaped slit 32. The elastic contact piece 5 deforms towards the cavity of the first connection cylinder 3, reducing the aperture of the first jack 31. The elastic contact piece 5 is in close contact with the pin, realizing the contact function without affecting the true roundness. At the rear end of the second connection cylinder 4, a second jack 41 is provided; one end of the round copper wire 2 is inserted into the second jack 41 and is riveted to the second connection cylinder 4, and the other end is welded to the PCB board.
[0018] Optionally, a number of riveting points 42 are distributed at intervals on the side wall of the second connection cylinder 4. The side wall of the second connection cylinder 4 and the round copper wire 2 are combined together through a riveting process to achieve a firm connection.
[0019] Optionally, the first jack 31 and the second jack 41 are in a frustum shape. The design of the frustum-shaped holes helps to guide the pin and the round copper wire 2 to be correctly aligned and inserted into the first jack 31 and the second jack 41 respectively, thus simplifying the assembly process.
[0020] One end of the terminal body 1 of the present utility model is connected to the pin through the first connection cylinder 3, and the other end is connected to the round copper wire 2 through the second connection cylinder 4, thereby realizing the connection of the circuit or system. Since the first connection cylinder 3 is provided with an elastic contact piece 5, when the pin is inserted into the cavity of the first connection cylinder 3, the elastic contact piece 5 can be pressed on the pin due to the elastic force, having a contact force with the pin, and realizing a firm connection between the first connection cylinder 3 and the pin; the side wall of the second connection cylinder 4 and the round copper wire 2 are combined together through a riveting process to achieve a firm connection between the second connection cylinder 4 and the round copper wire 2. The assembly is simple, and the length specification of the round copper wire 2 is not limited by the process and can be set according to needs. The structure of the present utility model is simple. The first jack 31 and the second jack 41 of the first connection cylinder 3 and the second connection cylinder 4 are processed by turning, and the U-shaped slit 32 is formed by cutting. The manufacturing cost is low and the connection is firm.
[0021] It should be understood that all the above embodiments are exemplary rather than restrictive.
