Description

  The present invention relates to a connector, and more particularly to a conductive terminal and a connector and a connector assembly to which the conductive terminal is applied.

  A B-to-B connector is a connector that is widely applied inside electronic products, and usually includes an outlet and a plug that interacts with the outlet. The outlet and the plug are each connected on the circuit board. When the plug and the outlet are inserted into each other, electricity is conducted to both circuit boards into which the plug and the outlet are inserted.

  In recent years, with the development of miniaturization of electronic products, the outer size of connectors has become even smaller. There is a known low-profile connector assembly (see, for example, Patent Document 1), which has a recess at the contact end of the plug terminal and a projection at the contact end of the outlet terminal. A stable electrical connection is formed between the plug and the outlet by combining the convex portion and the concave portion.

  Since the volume of the connector described above is very small, the terminal design is also very thin. When the plug is inserted or removed from the outlet, the terminals must be elastically deformed and held together. However, since stress is present between the terminals, the portion corresponding to the terminal is easily bent or cut off, which affects the electrical connection.

The elastic portion 485 is U-shaped and includes a first elastic arm 486 and a second elastic arm 487 that are connected to each other. The first elastic arm 486 is connected to the assembly portion 481 by the arc-shaped curved portion 483, thereby further increasing the connection strength between the elastic portion 485 and the assembly portion 481, and the outlet terminal 48 can cope with a larger attachment / detachment force. . The free end of the second elastic arm 487 of the outlet terminal 48 includes a contact portion 488 protruding outward.

  The outlet terminal 48 is installed in the insertion tank 431 of the outlet body 41 from the bottom to the top. Among them, the assembly portion 481 and the first elastic arm 486 are inserted into the outer portion of the insertion tank 431.

When both connectors have been inserted, the contact portion 488 of the outlet terminal 48 is elastically pressed by the contact section 121 of the conductive terminal 10 by the elastic recovery force of the outlet terminal 48.

  Since the fixed support arm 11 and the contact arm 12 of the conductive terminal 10 of the present invention approach a rigid structure, the amount of deformation of the conductive terminal 10 is small in the process of inserting and removing the plug 20 and the outlet 40. Thus, the conductive terminal 10 is effectively prevented from being bent or cut, and the stability of electrical connection between the connectors 20 and 40 is further increased. In addition, since the contact area 121 of the conductive terminal 10 has an uneven shape, the coupling force between the terminals 10 and 48 is further improved.
