In addition, with the continuous innovation of ADAS (advanced automatic driving assistance) technology, the traditional distributed architecture is difficult to adapt to development needs. The domain controller (DCU) integrated architecture based on domains has come into being. After high integration, the use of traditional connectors occupies a large space, and the solder-free plug-in fisheye terminal has come into being. The fisheye terminal is a separate plug-in board, and the connector matching port is integrated and injection molded on the back cover of the domain controller, which greatly reduces the size of the controller.

[0003] After checking the announcement number: CN220821973U, a welding-free spring-type fisheye terminal for automotive domain control is disclosed.

[0031] Embodiment

[0032] An automotive connector solderless fish-eye terminal, including a root body 1, and a distinguishing mark 4 is fixedly connected to the upper part of one end of the root body 1. The distinguishing mark 4 serves to facilitate the distinction between the front and back sides of the terminal.

[0033] An elastic member 6 is fixedly connected to the bottom end of the root body 1. A through-type fish-eye hole 5 is formed at one end of the elastic member 6. The fish-eye hole 5 facilitates the insertion during the connection of the elastic member 6, causing the elastic member 6 to be squeezed towards the middle during insertion.

[0034] The elastic member 6 is in an arc shape and is arranged in an opposite direction. The arc-shaped setting of the elastic member 6 makes the installation of the terminal more convenient.

[0035] An insertion pin body 7 is fixedly connected to the bottom end of the elastic member 6. The insertion pin body 7 serves to connect two power components and transmit current or signals.

[0036] Both the elastic member 6 and the insertion pin body 7 have strong plugging and unplugging forces, making the use effects of the elastic member 6 and the insertion pin body 7 better.

[0037] A functional layer assembly 2 is arranged inside the elastic member 6. The setting of the functional layer assembly 2 makes the service life of the terminal longer.

[0038] The functional layer assembly 2 includes a high-temperature resistant layer 22, which serves to resist high temperatures. One end of the high-temperature resistant layer 22 is fixedly connected to the inner wall of one side of the elastic member 6. A corrosion-resistant layer 23 is fixedly connected to the inner wall of the high-temperature resistant layer 22, which serves to resist corrosion, making the corrosion resistance of the elastic member 6 stronger.

[0039] A compressive layer 24 is fixedly connected to the inner wall of the corrosion-resistant layer 23. A tensile layer 25 is fixedly connected to the inner wall of the compressive layer 24. The use of the compressive layer 24 and the tensile layer 25 makes the pulling force of the elastic member 6 stronger.

[0040] A strong conductive layer 26 is fixedly connected to the inner wall of the tensile layer 25, and the inner wall of the strong conductive layer 26 is fixedly connected to the inner wall of one side of the elastic member 6. The strong conductive layer 26 makes the current transmission effect of the elastic member 6 better.

[0041] A sealing glue assembly 3 is arranged on the outer surface of the root body 1. The sealing glue assembly 3 serves to facilitate the improvement of the sealing performance at the connection.

[0042] The sealing glue assembly 3 includes two glue injection grooves 31. Both of the two glue injection grooves 31 are formed at the top end of the root body 1. The glue injection grooves 31 facilitate the injection of glue towards the root body 1.

[0043] The inner walls of both of the two glue injection grooves 31 are movably inserted with sealing caps 33, and the outer surfaces of the two sealing caps 33 are made of rubber. The sealing caps 33 serve to facilitate the sealing of the glue injection grooves 31.

[0044] A plurality of through glue seepage holes 32 are formed in one inner wall of each of the two glue injection grooves 31. The corresponding plurality of glue seepage holes 32 are equally spaced. The glue seepage holes 32 serve to seep the glue in the glue injection grooves 31 to seal the connection parts of the terminals, so that the fish-eye terminals have a waterproof and moisture-proof sealing effect during connection, improving the practicability of the terminal structure.

[0045] Working principle: First, the front and back of the terminal are distinguished by the distinguishing marks 4 on the root body 1, and the fish-eye terminal to be used is inserted onto the PCB board to be used.

[0046] During connection, the pin body 7 serves to connect two power components to transmit current or signals. The fish-eye holes 5 facilitate the insertion of the elastic member 6 during connection, causing the elastic member 6 to be squeezed towards the middle during insertion. This connection method achieves a high clamping force with a small pressing force, replacing the traditional welding connection.

[0047] Through the setting of the functional layer assembly 2 structure, the high-temperature resistant layer 22 serves to resist high temperatures, and the corrosion-resistant layer 23 serves to resist corrosion.

[0048] The use of the compressive layer 24 and the tensile layer 25 makes the pulling force of the elastic member 6 stronger, and the strong conductive layer 26 makes the effect of the elastic member 6 in transmitting current better, thereby improving the service life and effect of the fish-eye terminal.

[0049] Then, through the sealant assembly 3, glue liquid is injected into the glue injection grooves 31, and then the glue liquid seeps out through the plurality of glue seepage holes 32 to fill the gaps at the connection parts, so that the fish-eye terminals have a waterproof and moisture-proof sealing effect during connection.
