Wire connection terminal and wiring device having the same

The present invention relates to a wire connection terminal for connecting an electric wire to a terminal block, and a wiring device including the wire connection terminal.

Conventionally, a wiring device such as a socket or a switch including a wire connection terminal is used by being placed on a wall surface or the like. For example, in the wiring device (switch) 30 shown in Fig. 17, the device system is constituted by the main body 31 on the lower side in the drawing and the cover 32 on the upper side in the drawing. The main body 31 is provided with a terminal plate 34 connected to the contact portion 33, a lock spring 36 that presses the inserted electric wire 35 to the terminal plate 34 and mechanically holds the electric wire 35, and constitutes a release button (not shown). The terminal housing chamber 38 of the storage wire connection terminal 37 is configured. The cover 32 is provided with a rib 32a that presses the terminal block 34. The bottom surface of the terminal storage chamber 38 has an electric wire insertion opening 38a which is an insertion opening of the electric wire 35, and is opened.

When the electric wire 35 is connected to the electric wire connection terminal 37, first, the cover of the connected electric wire 35 is peeled off by a predetermined length to expose the core wire 35a, and then the core wire 35a of the electric wire 35 is fitted and pushed into the electric wire insertion opening 38a. Further, the core wire 35a of the electric wire 35 causes the lock spring 36 to meander and enter, and at this time, the core wire 35a is pushed against the terminal plate 34 by the elastic force of the lock spring 36, and the end portion of the lock spring 36 is fitted into the core wire 35a to lock the electric wire 35. The connection of the wires 35 is completed.

However, the insertion of the electric wire 35 is not perfect, and when the core wire 35a of the electric wire 35 is separated from the terminal plate 34 by various reasons such as external pressure, the lock spring 36 is energized to the terminal block 34. The lock spring 36 is formed of a stainless steel material or the like in order to increase the stress threshold value, so that the conductor resistance is extremely high. Therefore, when the lock spring 36 is energized, the heat generation is increased and the temperature rise is increased, which may shorten the life of the wiring tool 30. Therefore, in the wiring harness 30, in order to ensure safety, it is necessary to surely maintain the electrical conductivity between the electric wire 35 and the terminal block 34.

For this reason, for example, a wire connector has been disclosed in which a wire terminal inserted into the two groove portions from the opening portion of the cover is surrounded by the groove hole, and is electrically conducted in a reliable and durable manner (see Patent Document 1). Further, a wiring device has been disclosed which has a spring inside the conductor and includes a wire fall prevention pressing mechanism (see Patent Document 2).

Therefore, when the electric wire 35 is separated from the terminal plate 34 by the external pressure or the like, a situation in which the conductor resistance between the electric wire 35 and the terminal plate 34 cannot be ensured is low, and the heat generation of the electric wire connection terminal 37 is increased, and the life is increased. May be shorter.

Further, since the conventional electric wire connection terminal 37 is used to push the electric wire 35 to the terminal block 34 by the lock spring 36 made of stainless steel.
