Terminal device

Abstract

A terminal device includes a terminal piece for making contact with a core wire of an electric wire inserted into a housing through a wire insertion hole formed in the housing; a locking spring formed separately from the terminal piece for mechanically and electrically connecting the core wire to the terminal piece by gripping the core wire in cooperation with the terminal piece; and a release button for releasing mechanical connection between the terminal piece and the core wire maintained by the locking spring, by being operated through a manipulation hole formed in the housing and the release button is provided with a pressure contact portion for, when the core wire is not inserted, pressing to bend the locking piece such that a gap is formed between the terminal piece and the leading edge of the locking piece.

Description

technical field [0001] The invention relates to a terminal device with a quick connection terminal structure capable of connecting electric wires without using screws. Background technique [0002] In general, there have been terminal devices known as quick-connect terminal structures capable of connecting electric wires without using screws, so that electric wires can be easily connected to wiring devices such as switches or outlet sockets (see, for example, Patent Literature 1). Next, the configuration of such a terminal device will be described. [0003] Figure 6A and 6B Shown are terminal arrangements A1 and A3 for use in a switch 1 comprising a housing 3, a push button handle 2 provided on the front of the housing 3, and a contact device B housed in the housing in such a manner. body 3 so that it reverses each time the button handle 3 is pressed. Each of the terminal devices A1 and A3 includes a terminal piece 14b or 18b electrically connected to the contact device...

Problems solved by technology

[0010] However, since a gap is formed between the front edges of the terminal piece 14b and the locking piece 15b when the core wire 34 is not inserted, the above construction has a disadvantage: the reaction that the locking piece 15b presses the inserted core wire 34 against the terminal piece 14b The force, together with the contact pressure that clamps the core wire 34 between the front edges of the terminal piece 14b and the locking piece 15b, becomes stronger compared with the case where no gap is formed between the front edges of the terminal piece 14b and the locking piece 15b. Small

However, when the core wire 34 is not inserted, the locking spring 15 is not fixed in place and may occasionally move within the housing 3

Therefore, the lock spring 15 may be misaligned with the terminal piece 14b due to rotation or other movement of the lock spring 15 during the insertion of the core wire 34, and thus, the connection of the core wire 34 may become unstable.
