Abstract

PROBLEM TO BE SOLVED: To simultaneously perform connection and assembling, and keep a highly reliable connection for a long time by providing a conductor terminal base vertically on the rear end of a plug edge, and fixing a conductor presser on the reverse side of an opening and closing type upper lid thereon. SOLUTION: When a conductor consisting of a flat cord the coating on the tip of which is removed for a prescribed length is put on a conductor terminal base 3, the conductor is set near a cut groove 5 since the upper edge is inclined. When an upper lid 9 begins to close, a conductor presser 10 pushes the conductor down while pressing into the groove 5 to strongly bring the conductor into contact with the front surface and rear surface of the terminal base 3, and it keeps the contact when the lid 9 is closed. When the lid 9 is entirely closed after the conductor is pushed into the terminal base 3, a projection piece 15 on the reverse side is fitted to an upper lid fixture 16 provided on an upper vessel 8, and the lid 9 is firmly closed so that it cannot be opened by fingers. In opening, a regular (minus) driver is inserted into an upper lid opening hole 19 to wrench open it.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quick-connect wiring device for twisted wires, which enables a flat cord to be quickly and reliably connected to a wiring device such as a cap.

[0002]

2. Description of the Related Art Conventionally, there have been the following techniques and requests. (B) Wiring equipment that connects stranded wires with one touch, and the quick-connect caps that are currently on the market are covered wire type, in which a cone-shaped conical blade is provided at the rear end of the plug blade, and 0 0.75 mm ²
If you leave the flat cord of No. 4 as the covered wire and close the upper lid, the sharp conical blade breaks through the cover and contacts the conductor wire, but the range of use is limited due to point contact, and 6A125V
The capacity is up to 600W. (B) The quick-connect cap for 15A125V, which is commonly used at present, has not been put on the market for both coated wire and conductive wire. (C) For this reason, the user makes a spectacle ring with a conductive wire and assembles it by screwing it to the terminal block, but it requires skill and a considerable amount of work time. (D) Therefore, it has been a long time since not only people engaged in electrical work but also people who handle electrical equipment have requested the emergence of a quick-connect cap that enables quick and reliable wiring.

[0003]

Since the twisted wire is composed of several dozen thin annealed copper wires, the flat cord has the following characteristics. (A) The conductor wire is soft and can be easily folded to make a spectacle ring. (B) Since the thin annealed copper wires are twisted together, the surface easily slips. (C) Even if the conductor wires are strongly twisted together, they do not become as hard as a single wire, and even if you try to press them against the terminal block with a pressing blade,
It cracks, swells, or slips. In this way, the stranded wire, which is both an advantage and a drawback, cannot use a full terminal block like a single wire, so in the quick-connect cap, leave the flat cord covered on the sharp truncated blade,
The covering wire is pressed by the upper lid to make a hole in the covering and the tip of the conical blade is point-contacted for connection, but since the capacity is 600 W, it cannot be used for general purposes. The present invention has been made to eliminate these drawbacks.

[Means for Solving the Problems]

1. At the rear end of the plug blades (2) and (2) in the conductor cap (1) and the plug blades (2) and (2) facing the “T” shape, the conductor terminal blocks (3) and (3) Is provided vertically, and the wire retainers (10) and (10) are fixed to the rear surface of the openable upper lid (9) attached to the upper container (8). 2. At the rear end of the coated wire plug blades (2) (2), the coated wire terminal block (4)
(4) is provided vertically, and the covered wire pressers (11) and (11) are fixed to the back surface of the upper lid (9).

[0005]

[Action]

1. For conducting wire (a) When the conducting wire (12) (12) with the tip of the flat cord being covered with 16 layers is placed on the conducting wire terminal block (3) (3), the upper edge is inclined. Therefore, the lead wire (12) (1
2) is placed near the cut grooves (5) (5). (B) When the upper lid (9) is closed, the wire retainer (1
0) (10) pushes the lead wires (12) (12) into the cut grooves (5) (5) and bends them downward to bend the lead wire terminal blocks (3) (3) front and rear surfaces. When the upper lid (9) is closed, it keeps its connection.
A flat cord of 0.75 mm ² to 2.0 mm ² can be accommodated and used. 2. For covered wire (a) When the covered wire (13) (13) of the flat cord is placed on the covered wire terminal block (4) (4), the covered wire is inclined at the center, so the covered wire (13) (13) is placed near the flutes (6) (6). (B) When the upper lid (9) starts to be closed, the covered wire retainers (11) (11) fixed to the back surface are covered with the covered wire (13).
(13) is strongly pushed into the blade groove (6) (6). (C) The pressed coated wires (13) and (13) are cut off the coating on both sides by the thin blades of the blade-shaped grooves (6) and (6) to come into contact with the conducting wire. The blade portion contacts the conductor. (D) When the upper lid (9) is pushed to the final position, the tip of the conical blade (7) pierces the covered wire (13) (13) and stops. In this way, the both-sided blades of the blade-shaped grooves (6) (6) and the tips of the conical blades (7) (7) enter the conductor portion and make three-step contact. 0.75 mm ² of flat cord is a conical blade (7) (7)
, 1.25 mm ² and 2.0 mm ² are connected to the blade grooves (6) (6) and the conical blades (7) (7).
Due to the characteristics of the annealed copper wire, the difference in the thickness of the core wire is absorbed in the blade grooves (6) and (6), and even if the coating on both sides is cut,
The core wire is not scratched. 3. Top cover (a) Conductive wire (12) (12) or covered wire (13) (1
3) is pushed into each terminal block (3) (3) for conducting wire or terminal block (4) (4) for covered wire, and then the upper lid (9)
When all are closed, the protruding piece (1) on the back surface enters the upper lid stopper (16) provided on the upper container (8), and the upper lid (9) is tightly closed and cannot be opened with fingers. When opening, insert a flat-blade screwdriver into the top lid opening (17) and pry. (B) Stop the front lid (9) completely before closing it, then close the top lid (9).
If you fix the above, the conductor (12) (12) or the covered wire (1)
3) (13) can confirm the connected state. After checking, close all the upper lids (9). (C) When reusing, insert a flat-blade screwdriver into the top lid opening (17) and pry it open, then lead wires (12) (12).
Alternatively, the covered wires (13) and (13) can be removed respectively.
