Description

Technical Field

[0001] This application relates to the field of connector terminals, and particularly to a terminal and a connector. Background Art

[0002] In the field of electronic and electrical connections, a reliable connection between a terminal and a connector is crucial for ensuring the normal operation of a circuit and the stable transmission of signals. To achieve a firm interlock between the terminal and the connector, a barb structure is often used to enhance the stability of the connection. In this design, during the insertion of the terminal into the connector, the barbs on it will be deformed by the extrusion inside the connector. When the terminal is inserted in place, the barbs will be hooked onto the hanging platform of the connector through their elastic rebound characteristics, thus achieving the interlock between the two.

[0003] However, most of the barbs of the terminals in the prior art adopt a flat cross-sectional design. Although this design simplifies the manufacturing process to a certain extent, it gradually reveals many deficiencies in use. Due to the simple cross-sectional shape of the flat barb, it lacks sufficient strength and stiffness, resulting in excessive plastic deformation easily occurring when being extruded and deformed, thus affecting its rebound ability. When the terminal is inserted in place, the flat barb often cannot provide sufficient holding force, making the connection between the terminal and the connector less stable and prone to loosening or even falling off. Summary of the Utility Model

[0004] The purpose of this application is to provide a terminal whose barb is designed as an overall arc shape. This design aims to improve the strength and stiffness of the barb by optimizing the cross-sectional shape of the barb, so as to provide a more stable connection and a greater holding force during the process of the terminal being inserted into the connector and achieving interlock.

[0005] To achieve the above purpose, this application provides the following technical solutions:

[0006] A terminal includes a main body and a barb, wherein the barb has a fixed end and a free end. The fixed end is connected to the bottom of the main body, and the free end extends obliquely backward from the bottom of the main body. The barb is in an overall arc shape.

[0007] Further, the arc-shaped opening of the barb is arranged upward.

[0008] Further, the main body includes a connecting part, a conductor riveting claw part, and an insulating riveting claw part.

[0009] Further, the connecting part includes a first bottom wall, a first side wall, and a second side wall. The first side wall and the second side wall are symmetrically arranged on both sides of the first bottom wall.

[0011] Further, the first side wall includes a first vertical portion, a first bending portion, a second vertical portion, and a second bending portion. The first vertical portion extends vertically upward from the left side of the first bottom wall. The first bending portion extends obliquely leftward from the upper side of the first vertical portion. The second vertical portion extends vertically upward from the upper side of the first bending portion. The second bending portion extends horizontally rightward from the upper side of the second vertical portion.

[0033] The terms used in the implementation manners part of the present application are only for explaining the specific embodiments of the present application, rather than aiming to limit the present application. The implementation manners of the embodiments of the present application will be described in detail below with reference to the drawings.

[0034] As Figure 1 shown, a terminal 100 includes a main body 110 and a barb 120. The barb 120 has a fixed end 121 and a free end 122. The fixed end 121 is connected to the bottom of the main body 110, and the free end 122 extends obliquely backward from the bottom of the main body 110. The barb 120 is integrally arc-shaped. The design of the arc-shaped barb 120 in the present application enables its cross-section to more effectively disperse stress when being extruded, reducing the local stress concentration phenomenon, thereby improving the overall strength and anti-deformation ability of the barb 120. When the terminal 100 is inserted into the connector 200 and in place, the arc-shaped barb 120 can have stronger rigidity, ensuring a tight connection with the hanging platform of the connector 200, providing a greater holding force, and effectively preventing the terminal 100 from loosening or falling off due to external factors (such as vibration, impact).

[0035] The terminal 100 is made of metal material and formed by stamping. After the main body 110 of the terminal 100 is initially formed, without moving the position of the sheet, the stamping die is adjusted to the forming station of the barb 120. At this time, the upper die part includes metal cutting and bending edges, which cooperate with the arc-shaped grooves of the lower die. Through re-stamping, the upper die edge first stamps the bottom of the connecting part 111 of the main body 110 into the required arc shape, and then continues to cut and bend the metal downward to form a barb 120 with a fixed end 121 and a free end 122. The free end 122 extends obliquely backward from the bottom of the main body 110 and is overall arc-shaped, which is consistent with the shape of the arc-shaped groove of the die, making the forming of the barb 120 more convenient and simple.

[0036] As Figure 4 shown, in this embodiment, the arc-shaped opening 123 of the barb 120 is arranged obliquely upward. This design enables the barb 120 to make more effective use of the rigidity characteristics of the arc-shaped structure when being extruded by an external force, thereby enhancing the hanging effect with the hanging platform of the connector 200 and improving the stability of the connection.

[0037] As Figure 1 shown, the main body 110 includes a connecting part 111, a conductor riveting claw part 112, and an insulating riveting claw part 113. The connecting part 111 is the main part for the terminal 100 to connect with an external device (such as the connector 200). Through specific shape and size designs, it ensures that the terminal 100 can be accurately and smoothly inserted into the corresponding socket or hole to achieve electrical connection. The conductor riveting claw part 112 is the key part for electrical connection in the terminal 100. It is usually made of materials with good electrical conductivity (such as copper or copper alloy), and is tightly connected to the conductor part of the wire or cable through riveting or similar processes. In this way, when the terminal 100 is connected to an external device, current can be smoothly transmitted through the conductor riveting claw part 112. In addition to electrical connection, the conductor riveting claw part 112 also plays a role in fixing and protecting the wire or cable. It ensures that the wire or cable will not fall off or become loose from the terminal 100 through a tight riveting connection. At the same time, the structural design of the conductor riveting claw part 112 also takes into account factors to prevent damage to the wire or cable. The insulating riveting claw part 113 also plays a role in fixing and supporting the wire or cable.

[0038] As Figure 3 shown, in this embodiment, the connecting part 111 includes a first bottom wall 1111, a first side wall 1112, and a second side wall 1113. The first bottom wall 1111 is arc-shaped, corresponding to the arc of the barb 120, enhancing the stability of the overall structure. The first side wall 1112 and the second side wall 1113 are symmetrically arranged on both sides of the first bottom wall 1111, ensuring the balance and smoothness of the terminal 100 when inserted into the connector 200.

[0039] AsFigure 3 As shown, in this embodiment, the first sidewall 1112 includes a first vertical portion 1112a, a first bending portion 1112b, a second vertical portion 1112c, and a second bending portion 1112d. The first vertical portion 1112a extends vertically upward from the left side of the first bottom wall 1111. The first bending portion 1112b extends obliquely leftward from the upper side of the first vertical portion 1112a. The second vertical portion 1112c extends vertically upward from the upper side of the first bending portion 1112b. The second bending portion 1112d extends horizontally rightward from the upper side of the second vertical portion 1112c. The second sidewall 1113 includes a third vertical portion 1113a, a third bending portion 1113b, a fourth vertical portion 1113c, and a fourth bending portion 1113d. The third vertical portion 1113a extends vertically upward from the right side of the first bottom wall 1111. The third bending portion 1113b extends obliquely rightward from the upper side of the third vertical portion 1113a. The fourth vertical portion 1113c extends vertically upward from the upper side of the third bending portion 1113b. The fourth bending portion 1113d extends horizontally leftward from the upper side of the fourth vertical portion 1113c.

[0040] As Figure 3 shown, the first sidewall 1112 is composed of the first vertical portion 1112a, the first bending portion 1112b, the second vertical portion 1112c, and the second bending portion, and each part is connected in sequence to form a specific shape. Similarly, the second sidewall 1113 also includes a similar structure (the third vertical portion, the third bending portion, the fourth vertical portion, and the fourth bending portion), but in the opposite direction to achieve left - right symmetry. This design not only enhances the structural strength of the terminal 100 but also facilitates matching with the internal structure of the connector 200.

[0041] As Figure 3 shown, in this embodiment, the distance H1 between the first vertical portion 1112a and the third vertical portion 1113a is less than the distance H2 between the second vertical portion 1112c and the fourth vertical portion 1113c. This design helps to provide a guiding effect when the terminal 100 is inserted into the connector 200 and reduces the insertion resistance. At the same time, a first contact protrusion 114 is provided on the right sidewall of the second vertical portion 1112c, and a second contact protrusion 115 is provided at the corresponding position of the fourth vertical portion. These two protrusions play a contact role when the terminal 100 is connected to the connector 200, further improving the connection reliability.

[0042] As Figure 3As shown, in this embodiment, a first contact protrusion 114 is provided on the right side wall of the second vertical portion 1112c, and a second contact protrusion 115 is provided on the fourth vertical portion corresponding to the first contact protrusion 114. Through the design of the bending portion, the first side wall 1112 and the second side wall 1113 have a certain elasticity as a whole. This elastic design is particularly important when the terminal 100 is connected to the connector 200. When the male end is inserted, the side walls will be subjected to a certain extrusion force and undergo elastic deformation. This deformation, in cooperation with the first contact protrusion 114 and the second contact protrusion 115, not only helps to better adapt to the internal structure of the connector 200 but also provides an additional holding force during the insertion process to prevent the terminal 100 from loosening or falling off under vibration or external forces.

[0043] As Figures 5 to 7 shown, this embodiment also provides a connector 200 including the above-mentioned terminal 100. A limiting elastic piece 210 is provided at a position corresponding to the barb 120 on the connector 200. When the terminal 100 is inserted into the connector 200, the barb 120 first contacts the limiting elastic piece 210 and causes it to undergo elastic deformation; as the terminal 100 continues to be inserted, the barb 120 passes over the limiting elastic piece 210 and rebounds to its original position. At this time, the limiting elastic piece 210 exerts a certain pressure on the barb 120, thus achieving a firm connection between the terminal 100 and the connector 200. This design not only simplifies the structure of the connector 200 but also improves the convenience and reliability of the connection.
