TECHNICAL FIELD

[0001] The present application relates to the field of terminal technology, in particular to a large-current sheet terminal. BACKGROUND

[0002] The connection terminal is a kind of accessory product for realizing electrical connection, which is widely used in industrial automation and electronic and electrical fields. The connection terminal belongs to the category of connectors, and its consumption gradually increases with the improvement of industrial automation degree and the strictness of industrial control requirements.

[0003] Two common types of connection terminals are round terminals and sheet terminals. The round terminal usually adopts a press-fit or threaded connection method, which is stable in connection, good in sealing, and easy to install and maintain. However, compared with the sheet terminal, the round terminal usually has higher manufacturing and installation costs, and the round terminal has a larger volume, which is not suitable for space-limited application scenarios. The sheet terminal has low manufacturing cost and is suitable for mass production, and the sheet terminal occupies small space, which is suitable for high-density wiring and space-limited equipment. However, the current-carrying capacity and connection stability of the sheet terminal are weaker than those of the round terminal, so the application of the sheet terminal is limited.

[0004] According to the related technology in the above, the inventors believe that the current-carrying capacity and connection stability of the sheet terminal are weak, thereby limiting the application and development of the sheet terminal. CONTENT OF THE UTILITY MODEL

[0005] In order to solve the above technical problems, the present application provides a large-current sheet terminal.

[0008] By adopting the above technical scheme, the wave structure of the reed increases the number of contact points, thereby improving the contact area of the reed and the male terminal, and further improving the current-carrying capacity of the large-current sheet terminal. The present application enhances the installation stability of the reed and the connection stability of the large-current sheet terminal by arranging the limiting block, the first limiting hole and the clamping block.

[0009] Preferably, the shell is provided with a clamping groove in communication with the insertion opening, which is used for limiting the male terminal inserted into the insertion opening.

[0010] By using the above technical scheme, the clamping groove limits the male terminal, thereby reducing the left and right shaking of the male terminal, and further improving the connection stability of the large-current blade terminal.

[0011] Preferably, the end of the spring sheet close to the insertion opening is connected with a guide sheet arranged obliquely.

[0012] By using the above technical scheme, the guide sheet is arranged to guide and limit the inserted male terminal, thereby improving the connection stability of the large-current blade terminal.

[0013] Preferably, the shell is provided with a positioning hole for facilitating the installation of the shell.

[0014] By using the above technical scheme, the positioning hole is arranged to facilitate the quick installation and positioning of the large-current blade terminal, and facilitate the connection of the large-current blade terminal with the connector.

[0015] Preferably, the shell is provided with a second limiting hole for limiting the spring sheet body.

[0016] By using the above technical scheme, the second limiting hole further improves the connection stability of the spring sheet body and the shell.

[0017] In summary, the present application has the following beneficial technical effects:

[0018] 1. The present application increases the number of contact points between the spring sheet and the male terminal by arranging the spring sheet with a wave structure, thereby increasing the contact area and further improving the current carrying capacity of the large-current blade terminal.

[0019] 2. The present application improves the installation stability of the spring sheet body and the connection stability of the large-current blade terminal by arranging the limiting block, the first limiting hole, the second limiting hole and the clamping groove. BRIEF DESCRIPTION OF DRAWINGS

[0030] The shell 1 is provided with clamping grooves 14 communicating with the insertion port 11, and the clamping grooves 14 are used for limiting the male terminal inserted into the insertion port 11. The number of the clamping grooves 14 is two, the two clamping grooves 14 are symmetrically distributed at the two ends of the insertion port 11, and the two clamping grooves 14 are used for limiting the male terminal, thereby reducing the phenomenon that the male terminal shakes left and right, and improving the connection stability of the male terminal.
