Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present application relates to a compression type electric wire connector used for branch connection in electric wiring work.

[0002]

2. Description of the Related Art A conventional ring sleeve has a single inner portion, and a plurality of electric wires are mixed therein, crimped with dedicated crimping pliers, and then wrapped with an insulating tape or the like. The connector inserts electric wires one by one between the conductive plate and the spring piece, and has a structure in which a spring piece with a weak pressing force that can be inserted by the pressing force of one electric wire presses the electric wire.

[0003]

Since the ring sleeve mixes a plurality of electric wires into one hole, the terminals may be imperfectly connected by being crimped while being complicated and also when a large number of electric wires are put in. In a small number of cases, there are many problems such as damage caused by deformation of the electric wire by excessively pressing with the dedicated crimping pliers to the same fixed position, troublesome carrying of the dedicated crimping pliers, and troublesome insulation processing work after connection. there were. Since the plug-in type wire connector has a structure in which the conductive plate and the pressing pressure spring are pushed open with a single wire to connect, the spring pushing pressure is inevitably weak, and after connection, many joints are used in narrow joint boxes. In order to accommodate the branch connection, there is a problem that the weak spring pieces are further shocked by bending, twisting, or pushing them too hard, so that the connecting function of the spring pieces is significantly deteriorated.

[0004]

Therefore, as a means for solving the above-mentioned problems of the prior art, a metal material such as a copper material having excellent conductivity and durability is used, and the sleeve is formed into a corrugated shape in the previous step, and the inside thereof is formed. Separate the wires by wrapping them in the multiple compression holes formed in each, insert and fix them in the space at the back of the opening of the insulating case, and set the compression tool in the mounting port provided in the insulating case. If you press the compression tool and compression receiver of the product that is made up with the pliers etc. held by your hand, either the linear pressure part, the end pressure part, or the single pressure part at the tip of the compression tool will be the entire corrugated groove of each corrugated sleeve. Alternatively, both ends or a part or a plurality of points may be point-pressed to individually envelop each electric wire contained in the pressurizing hole and firmly fix the electric wire.

[0007]

The main feature of the present invention is that a plurality of compression holes 2 are provided inside the corrugated sleeves A1, B14, C16, and D17, and the compression holes 2 are formed in the opening 10 of the insulating case 3.
Of the compression tool 6 and the compression receiver 9 are sandwiched between the compression tool 6 and the compression receiver 9 with pliers or the like so that the convex portion 8 engages with the concave portion B5. When compressed to, the linear pressure portion 7 presses the inter-wave groove 22 in a slender and long manner, or the end pressure portion 21 compresses only to both ends of the inter-wave groove 22, or the single pressure portion 23 applies one or more points to each inter-wave groove 22. A single pressure is applied to the portion, and the electric wire 11 is strongly wrapped in the compression hole 2 so that the entire hole is firmly compressed and connected.

Since each of the corrugated sleeves is molded into a corrugated shape in advance, most of the required compression depth is already compressed, and the compression force of the compression tool 6 is limited to the final stage. The grip force of the is light and good, and the powerful special pliers with a long lever are unnecessary, and it can be completely compressed by the pressure of the general pliers on hand.

Since the compression hole 2 is slightly larger than the electric wire 11 and can be inserted without resistance, it can be used as a single wire.

As shown in FIG. 8, the corrugation of each corrugated sleeve has a characteristic that when only one is molded, the molding process is halved and it is very simple. 2 is formed and wraps around the wire 11,
The effect can be obtained without change.

Each sleeve is made of a material having a high conductivity and an excellent durability due to the rigidity of metal to form a corrugated cylindrical body to obtain a complete conductive effect, and the entire wire 11 is compressed so as to individually wrap it. Therefore, the electric performance is maintained without loosening the connection part even if it is pushed into the joint box after use and is given a shock such as twisting and twisting. Moreover, each sleeve and the compression tool 6 are simply set in the insulating case 3. Due to the structure, the product shape is small, and therefore many can be stored in the joint box, and it is easier to carry.
