Description

Technical Field

[0001] This utility model relates to the field of stamping terminal technology, and in particular to a stamping terminal for an automotive connector. Background Technology

[0002] In the automotive connector field, stamped terminals are key components for current transmission, and their performance directly affects the stability of the automotive electrical system. However, existing automotive connector stamped terminals suffer from several problems during long-term use: First, frequent insertion and removal of the terminals can lead to a gradual decrease in clamping force over time, resulting in poor contact, severely affecting the stability of current transmission, and potentially interfering with the normal operation of automotive electrical equipment. Second, the direct impact force generated during insertion and removal can easily act on the terminal's spring structure, causing deformation and wear, significantly shortening the overall lifespan of the terminal, and increasing maintenance costs and replacement frequency. Third, the springs used for auxiliary clamping in some terminals are prone to dislodging from their original fixed position under long-term stress and vibration, losing their elasticity and further exacerbating the problem of poor clamping effect. Fourth, automotive operating conditions are complex, facing various environmental factors such as vibration and temperature changes. The clamping effect of existing terminals on male terminals cannot be consistently guaranteed, resulting in insufficient reliability and durability, and failing to meet the requirements of long-term stable automotive operation.

[0026] Reference Figure 1-6 This utility model provides a stamped terminal for an automotive connector, comprising: a female terminal 1, a wire core connecting part 2 fixedly connected to one end of the female terminal 1, and a cable connecting part 3 fixedly connected to the end of the wire core connecting part 2 away from the female terminal 1.

[0027] Specifically, when installing the female terminal 1, the wire is placed at the cable connection part 3, and the wire core is placed at the wire core connection part 2. Then, the cable connection part 3 and the wire core connection part 2 are squeezed to compress them into a cylindrical shape, thereby fixing the female terminal 1 to the wire and the wire core. When in use, the male terminal is inserted into the female terminal 1 to complete the connection.

[0028] A plug tube 9 is fixedly connected to one end of the female terminal 1 away from the wire core connection part 2. An extension part 10 is fixedly connected to the side surface of the plug tube 9. A spring piece 11 is fixedly connected to one end of the extension part 10 away from the plug tube 9. A spring 14 is fixedly connected to the side surface of the spring piece 11. A fixing plate 12 is fixedly connected to one end of the spring 14 away from the spring piece 11. The side surface of the plug tube 9 is fixedly connected to the fixing plate 12. There are two fixing plates 12, which are symmetrically distributed.

[0029] Specifically, the other end of the female terminal 1 is provided with a plug tube 9 to fix the male terminal inserted into the female terminal 1. The plug tube 9 has an extension 10 at the slot on its surface, and the end of the extension 10 is provided with a spring piece 11. By inserting the spring piece 11 into the corresponding slot on the male terminal, the male terminal and the female terminal 1 are fixed. The plug tube 9 is also provided with a fixing plate 12. A spring 14 is provided between the fixing plate 12 and the spring piece 11. The spring force of the spring 14 allows the spring piece 11 to better fit with the male terminal and clamp the male terminal. During frequent insertion and removal, it can effectively reduce the poor contact caused by the decrease in clamping force, thereby improving the durability of the terminal. In addition, the spring 14 can also provide a certain buffering effect, reducing the direct impact of insertion and removal force on the spring piece 11, reducing the deformation and wear of the spring piece 11, and thus improving the service life of the terminal.

[0030] A second fixing block 15 is fixedly connected to the side surface of the fixing plate 12. The end of the spring 14 near the fixing plate 12 is fixedly connected to the second fixing block 15. A first fixing block 13 is fixedly connected to the side surface of the spring piece 11. The end of the spring 14 near the spring piece 11 is fixedly connected to the first fixing block 13.

[0031] Specifically, fixing block 2 15 and fixing block 13 are installed on fixing plate 12 and spring piece 11 respectively, which fix the two ends of spring 14 for secondary fixation, improve the fixing effect of spring 14, and prevent spring 14 from detaching from fixing plate 12 and spring piece 11 during use, thus affecting the clamping effect.

[0032] A dovetail buckle 6 is fixedly connected to the side surface of the female terminal 1. A dovetail groove 7 is provided on the side surface of the female terminal 1. There are multiple dovetail buckles 6 and they are evenly distributed. The dovetail groove 7 and the dovetail buckle 6 match each other.

[0033] Specifically, the female terminal 1 has dovetail buckles 6 and dovetail grooves 7 on its two side surfaces before installation. After matching the dovetail buckles 6 and dovetail grooves 7 of the female terminal 1, the female terminal 1 is squeezed to form a cylindrical structure. At this time, the dovetail buckles 6 and dovetail grooves 7 are tightly spliced, and the connection naturally forms a butt joint 8. The setting of dovetail buckles 6 and dovetail grooves 7 makes the structure of the female terminal 1 stable and not easy to crack after splicing. The other end of the cable connection part 3 is provided with a mounting plate 4. During the installation of the female terminal 1, mounting parts such as bolts and screws can be used to pass through the mounting holes 5 to fix the mounting plate 4 to the required parts, thereby fixing the female terminal 1 to the required parts and improving the fixing effect.

[0034] Working principle: During installation, the wire is first placed in the cable connector 3, and the core is placed in the core connector 2. The two are then pressed together to form a cylindrical shape, thus fixing the female terminal 1 to the wire and core. Before installing the female terminal 1, the dovetail clips 6 and dovetail grooves 7 at both ends are matched. After pressing the female terminal 1 into a cylindrical shape, the two are spliced ​​together, forming a butt joint 8, ensuring the structural stability of the female terminal 1 after splicing and preventing cracking. Next, bolts or other mounting components are passed through the mounting holes 5 of the mounting plate 4 to fix the mounting plate 4 to the required component, thereby fixing the female terminal 1. In use, the male terminal is inserted into the plug tube 9 at one end of the female terminal 1. The spring piece 11 at the end of the extension 10 at the slot of the plug tube 9 is inserted into the male terminal slot. The spring 14 between the fixing plate 12 and the spring piece 11 uses its elasticity to make the spring piece 11 fit and clamp the male terminal, reducing poor contact caused by insertion and removal, buffering impact, and extending the service life of the terminal. The fixing block 13 and fixing block 2 15 fix the two ends of the spring 14 to prevent it from coming off, and finally the connection between the male terminal and the female terminal 1 is completed.
