Abstract

PURPOSE:To facilitate wire insertion/extraction and ensure connection, by pushing a wire in an insertion hole, rotating a releasing member at the tip of the wire via a detecting member, locking the wire by a locking spring, and when the wire is extracted, pushing in an operating member to release a locking spring. CONSTITUTION:When a wire 15, in which a given-length coating is removed, is inserted in a wire insertion hole to pushedly press an abutting part 30 by the tip of a wire 15, a detecting member 6 is rotated with an axis 31 as a center, the tip part of a releasing member 3 is pushed in a wire insertion direction by a pushedly pressing part 32 to rotate the member 3 in a direction, in which a locking spring 2 is loosed, to rotate a key part 24. Consequently the pushedly pressing part 32 is more rotated to be apart from the member 3 while an interlocking rod 29 is moved to a slit 23 side. Resultingly the slit 23 is moved by the interlocking rod 29, and the member 3 is moved due to the returning force of the spring 2 and the returning spring 27 of an operation member 4 to return the spring 2, locking the wire 15. The operation part member 4 is returned to an original condition. When the wire 15 is to be extracted, the member 4 is pushed in to release the spring 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quick connection terminal device.

[0002]

2. Description of the Related Art A conventional example is shown in FIGS. That is, in this quick-connect terminal device, the U-shaped portion 106 is bent at the end of the conductive plate 101 mounted in the body 100, and the locking spring 102 facing the wire insertion hole 103 is mounted inside thereof. . Also, when the connected electric wire is removed, the locking spring 102
A release button 104 for extra bending is provided on the body 100 and is arranged so as to contact a part of the locking spring 102.

When the electric wire conductor is stripped to a predetermined length and the conductor of the electric wire is inserted into the electric wire insertion hole 103, the electric conductor of the electric wire enters the locking spring 102 without bending and the locking spring 1
The pressing force of 02 pushes the conductor of the electric wire against the U-shaped portion 106 to complete the connection of the electric wire. On the other hand, when disconnecting the electric wire, a driver is inserted into the hole 105 of the release button 104 and the release button 104 is pushed downward to lock the lock spring 1.
Bend 02 and pull out the wire while disconnecting it from the conductor.

[0004]

However, in this quick-connect terminal device, the electric wire is pressed against the U-shaped portion 106 by the force of inserting the electric wire to bend the locking spring 102 and the repulsive force of the locking spring 102. It depends on the power to slide the wire in the state. Normally, the inserting force of the electric wire is set so that it can be pushed in by the force of a person, but the locking spring 1 is used to ensure the contact between the electric wire and the terminal plate even if the diameter of the electric wire is different.
Since the spring constant of 02 is determined, the insertion force of the electric wire increases as the diameter of the electric wire increases, and the electric wire may be inserted halfway. Further, when releasing the electric wire, the electric wire has to be pulled out while pushing the release button 104 with a jig such as a screwdriver, which makes the work difficult. Further, the body 100 may be damaged by the force for pushing the release button 104 to bend the locking spring 102.
