Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, in particular to a wiring terminal with stable structure. Background Art

[0002] Wiring terminals are an indispensable part of electrical connections and are widely used in various electrical and electronic devices. Traditional wiring terminals are usually made of metal materials, mainly used to fix wires or cables and ensure the safety and reliability of electrical connections. Common wiring terminals include a clip body for clamping wires and a connecting piece for fixing, and connecting holes are provided on the connecting piece. It can be seen that common wiring terminals are usually in the shape of a sheet, and the structure of the sheet is usually flat, which makes their bending strength in the direction perpendicular to the sheet relatively low. When subjected to lateral external forces (such as during installation or due to external vibration), the sheet is prone to bending deformation, thus affecting the stability of the connection. Moreover, due to the thin thickness of the sheet terminals, their shear strength is often not as good as that of other types of terminals, and in high-load or high-frequency vibration application scenarios, cracks or fractures may occur at the connection points of the terminals. Summary of the Invention

[0003] Objective of the utility model: In order to overcome the defects of the prior art, the utility model provides a wiring terminal with stable structure, solving the problems of low bending strength and insufficient shear strength.

[0004] Technical solution of the utility model: It includes a clip body and a connecting piece. A connecting hole is provided in the connecting piece. A concave depression is provided on the top surface of the connecting piece, and a convex protrusion is formed by the depression extending from the depression to the bottom surface of the connecting piece.

[0005] Adopting the above technical solution, the depression and the protrusion are similar to the reinforcing rib structure of a beam, which can improve the ability of the connecting piece to resist lateral bending, increase the overall rigidity of the connecting piece. This structure can also disperse the shear force, reduce local stress concentration, thereby reducing the risk of cracks or fractures at the connection points of the terminals, increasing its shear strength, and ultimately improving the reliability and safety of the electrical connection of the wiring terminal.

[0006] In a possible design, the connecting piece is bent relative to the clip body, and the depression and the protrusion extend to the bending position and approach the clip body.

[0007] Adopting the above design can improve the bending strength of the bending position, effectively disperse the stress at the bending part, reduce the stress concentration at the bending point, thereby reducing the risk of fracture at the bending position.

[0008] In a possible design, the depression is located at the middle position in the width direction of the connecting piece.

[0009] With the above design, the design is more balanced, which helps to balance the stress distribution.

[0010] In a possible design, a limiting block protruding outward is integrally provided on the outer edge of the connecting piece.

[0011] With the above design, the limiting block can be used as a positioning reference during the installation process, simplifying the installation process, helping to ensure the correct position of the connecting piece during installation, and reducing problems caused by improper installation.

[0012] In a possible design, a number of clamping grooves are also provided on the outer edge of the connecting piece.

[0013] With the above design, the clamping grooves can be used in cooperation with the corresponding buckles at the installation position to ensure the accurate position of the connecting piece during the installation process.

[0014] In a possible design, a number of linearly arranged friction grooves are provided on the inner side of the clamping body.

[0015] With the above design, the friction grooves can increase the friction coefficient between the clamping body and the wire, helping to reduce the loosening of the wire caused by vibration. Description of the Drawings

[0020] As Figures 1 - 3The shown structurally stable terminal block includes a clamping body 1 and a connecting piece 2. A connecting hole 21 is formed in the connecting piece 2. A concave depression 22 is provided on the top surface of the connecting piece 2, and a convex protrusion 23 is formed by the bottom surface of the connecting piece 2 being concave downward from the depression 22. During the processing, the depression 22 and the protrusion 23 are formed by stamping equipment. Therefore, the positions of the depression 22 and the protrusion 23 correspond to each other. The depression 22 and the protrusion 23 are generally rectangular. The depression 22 is gradually sunken from the top surface of the connecting piece 2, and there is a transitional slope between the bottom of the depression 22 and the top surface of the connecting piece 2. The thickness at the position of the depression 22 is basically the same as the thickness of the connecting piece 2. Compared with the planar connecting piece 2, the depression 22 and the protrusion 23 have an effect similar to that of a reinforcing rib, which can improve the bending strength and enhance the shear strength, so that the terminal block can adapt to the installation environment of high-frequency vibration.

[0021] The connecting piece 2 is bent relative to the clamping body 1 by approximately 90 degrees, and the depression 22 and the protrusion 23 extend to the bending position and approach the clamping body 1, so that the bending position also has the depression 22 and the protrusion 23. The bending position is prone to problems such as fracture and decline in mechanical properties due to the force of bending. Therefore, the use of the depression 22 and the protrusion 23 can effectively improve the structural strength and keep the bending position structurally stable.

[0022] The depression 22 is located at the middle position in the width direction of the connecting piece 2. The position of the depression 22 is more balanced relative to the entire connecting piece 2, which is beneficial to convenient processing and stress dispersion.

[0023] A limiting block 24 protruding outward is integrally provided on the outer edge of the connecting piece 2, and a plurality of clamping grooves 25 are also formed on the outer edge of the connecting piece 2. The combined use of the limiting block 24 and the clamping grooves 25 can improve the fixing between the connecting piece 2 and the installation position. In a vibrating or moving environment, this enhanced fixing helps to reduce the risk of connection loosening.

[0024] There are a number of linearly arranged friction grooves 11 on the inner side surface of the clamping body 1. When the wire is inserted into the clamping body 1, the friction grooves 11 can increase a certain amount of friction and reduce the possibility of the wire detaching abnormally.
