Description

Connection terminals Technical Field

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

[0002] Connecting terminals are key components in connectors used to achieve electrical connections. A connecting terminal typically includes a main body with wiring portions and connecting portions at its front and rear ends. The wiring portions secure the wire harness to the connector, ensuring it won't loosen or fall off during use and guaranteeing connection stability. The connecting portions are either insert-shaped or slot-shaped depending on whether they are for the corresponding male or female connector. When the male and female connectors are connected, the two connecting portions facilitate current or signal transmission of the wire harness. After the connecting terminal is installed on the connector, a spring with elastic movement is provided on the main body to ensure a limiting effect between the terminal and the connector. This elastic movement facilitates insertion into the connector for installation. However, in existing connecting terminals, the strength of the limiting spring is relatively poor, leading to deformation and affecting subsequent stability and performance. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a connection terminal with higher strength and greater stability.

[0004] To achieve the above objectives, this utility model provides a connecting terminal, including a main body and a wiring portion. The main body is provided with a spring piece, and a retaining edge is provided on one side of the main body corresponding to the width direction of the spring piece. The retaining edge and the spring piece are in clearance fit. The spring piece is provided with a reinforcing portion and a limiting protrusion. The reinforcing portion is provided on the other side of the spring piece and is bent toward the inner cavity of the main body. The limiting protrusion is provided on one side of the end of the spring piece, and the retaining edge is provided with a limiting groove corresponding to the movement trajectory of the limiting protrusion.

[0005] The advantages of the above technical solution are as follows: By setting a retaining edge and a reinforcing part on the main body and the spring respectively, the retaining edge is located on one side of the spring in the width direction, which can limit the displacement of the spring in the width direction. When the spring is subjected to external force, such as vibration during the assembly process with the connector or during use, the retaining edge can prevent the spring from shaking or shifting excessively, improve the strength of the connecting terminal, and facilitate the installation of the connecting terminal. On the spring and the retaining edge, mutually cooperating limiting protrusions and limiting grooves are respectively set to limit the movement of the spring and enhance stability. On the other side of the spring, a reinforcing part formed by bending is set, which increases the thickness of the corresponding part of the spring, making the corresponding part less prone to bending or deformation. This limits the deformation position of the spring when subjected to external force, improves the strength of the spring, ensures the stability of the connecting terminal after it is installed in the connector, and improves the service life of the product.

[0006] The present invention can be further configured such that: a first notch is provided between the reinforcing part and the main body, and the first notch is provided near the root of the spring piece.

[0007] By further designing the spring clip by creating a first notch between the reinforcing part and the main body, the thickness of the spring clip near the root is reduced, thereby limiting the deformation position and ensuring a stable and reliable movement trajectory during installation.

[0008] The present invention can be further configured such that: the front end of the spring sheet is bent to form an arc portion and an abutment portion, the abutment portion can swing with the spring sheet until its height is less than that of the arc portion, and the abutment portion can return with the spring sheet to be parallel to the end face of the main body.

[0009] By further designing the spring, an arc portion and an abutment portion are provided at the front end of the spring. The abutment portion can swing with the spring until its height is less than that of the arc portion, and the abutment portion can return with the spring to be parallel to the end face of the main body. During installation, the product mainly uses the arc portion of the spring to cooperate with the connector, and the shape of the arc portion reduces wear and bumps. After installation, the abutment portion, which is parallel to the end face of the main body, cooperates with the connector to abut and limit the connection, ensuring strength.

[0010] The present invention can be further configured such that: the spring sheet has a second notch between the corresponding abutting part and the reinforcing part.

[0011] By further designing the spring, a second notch is provided between the contact part and the reinforcing part to prevent contact between the contact part and the reinforcing part, thus facilitating processing.

[0012] The present invention can be further configured such that: the main body includes an inlet and an extension, the inlet is located at one end of the main body corresponding to the wiring part, the extension is located below the end of the inlet corresponding to the baffle, and the extension can swing to the other side of the inlet and cover the top of the inlet.

[0013] By further designing the extension portion on the main body, the extension portion is positioned below the end of the cable inlet corresponding to the guard edge, and can swing to cover the top of the cable inlet. On the one hand, the extension portion can provide additional restraint for the wire harness inserted into the cable inlet. On the other hand, the extension portion can also form an abutment restraint with the connector, better matching the connector and enhancing the stability of the product.

[0014] The present invention can be further configured such that: the wiring portion includes a first limiting piece and a plurality of recesses, the first limiting piece extends from the wiring portion toward both sides, the recesses extend from one side of the first limiting piece through the wiring portion to the other side of the first limiting piece, and the plurality of recesses are spaced apart.

[0015] By further configuring the wiring section, a first limiting piece and several recesses are provided on the wiring section. When the wiring section extends to both sides to form the first limiting piece, and it is bent and pressed against the wire harness, the recesses can enhance the friction between the wiring section and the wire harness, thereby strengthening the connection strength.

[0016] The wiring section includes a first limiting piece and two second limiting pieces. The first limiting piece and the second limiting piece are arranged sequentially in a direction away from the main body, and the two second limiting pieces are staggered.

[0017] By further designing the second limiting piece, which is offset, the contact area between the second limiting piece and the wire harness can be increased after bending and pressing it onto the wire harness, thus enhancing the limiting effect. Attached Figure Description
