しにくいという欠点があつた。 Conventionally, there are plugs for electrical appliances, as shown in Figures 1 and 2, in which a blade-shaped ridge for preventing the cord from being removed is provided near the cord insertion opening, but the upper and lower cases 2 and 3 are exactly the same. When assembling, the insert blade 1 may float or the cord 10 may be placed on the blade-shaped protrusion of the lower case 3.
The disadvantage was that the cord 10 would shift or not be fixed when it was covered, making it difficult to assemble.

０の端末とを接続せしめる。 The configuration of the embodiment is as shown in FIGS. 3 to 6. 3 is a lower case, 2 is an upper case, which, together with the lower case 3, is made of a synthetic resin insulating material, and is provided with notched grooves 4 and 5 for positioning two blade holders 9 in parallel, as shown in FIG. Cord positioning portions 8 are provided facing the insertion openings 6 of 10 and protruding in two directions perpendicular to the grooves 4 and 5 provided on both sides. The blade-shaped protrusion 7 according to the present invention is on the top,
In the vicinity of the insertion opening 6 of the lower cases 2 and 3, that is, between the cord positioning part 8 and the other flat or blade-shaped holding surface 16 facing the blade-shaped protrusion 7, its width is the same as the width of the cord positioning part 8. It is provided to match the dimensions. The shape of the blade-shaped protrusion 7 is a symmetrical saw blade shape, and is formed approximately parallel to the tip of the cord positioning part 8, so that the blade direction is set so as to bite against the tension direction of the cord 10 as shown in FIG. Install.
However, the structural difference between the upper case 2 and the lower case 3 is as shown in FIG. 3 is that a cord storage section 12 is provided, which is a concave portion that engages the cord 10 from the mating surface 11, and a blade-shaped or flat pressing surface 16 is provided at the bottom of the cord storage section 12. 14 is code armor,
The cord 10 is interposed between the cord 10 and the insertion openings 6 of the upper and lower cases 2 and 3 to prevent the cord from bending. Reference numeral 13 denotes a mounting screw for fixing the upper and lower cases 2 and 3. 15 is a set screw, blade holder 9 and code 1
Connect to terminal 0.

いるため咬止力は増大する。 The function of the present invention is that during assembly, as shown in Figure 3, the tip of the cord 10 and the blade holder 9 are fixed with a set screw 15,
This is attached to the lower case 3, and the cord 10 is formed by a concave portion that engages the mating surface 11 which is opposed to the surface of the blade-shaped protrusion 7 of the upper case 2 and constitutes a blade-shaped surface or a flat holding surface 16. Code 1 in cord storage section 12
0 and insert the blade receiver 9 into the grooves 4 and 5 of the lower case 3.
At the same time, the cord positioning part 8 is secured to the outside of the protruding part 8, and is housed between the inner surface of the lower case 3 and the upper case 2. The cord 10 is reliably held by the blade-shaped protrusion 7 provided on the case 2 and the pressing surface 16 of the lower case 3. Therefore code 1
The external force applied to the blade holder 9 and the cord 10 is not applied to the tension direction. Further, when the blade-shaped protrusion 7 and the holding surface 16 are blade-shaped surfaces, the direction in which the blades are formed is perpendicular to the axis of the cord 10, so that the biting force increases.

グとなる。 According to the present invention, a cord positioning part is provided, and a blade-shaped protrusion is provided near the insertion port to hold the cord, and the blade surface of the blade-shaped protrusion is positioned near the mating surface of either the upper or lower case. By providing a blade-shaped surface or a flat holding surface in the cord storage portion, the other being a concave portion facing the blade surface of the blade-shaped protrusion, it is possible to improve the ease of assembly without the cord and blade holder coming off. Furthermore, the blade-shaped protrusion catches external forces applied to the cord and reliably prevents it from coming off the case, and the electrical appliance has improved durability as no tension is applied to the connection part. It becomes a plug for use.
