Description

[Detailed Description of the Invention] The present invention relates to a cord connector for connecting cords to various electrical appliances.

With conventional cord connectors, the entire cord was rotated to be fixed to the appliance body with the cord attached, and the plug was attached/detached, so the cord connected to the cord connector inserted into the appliance was narrow during installation. The disadvantage was that the cord could become kinked or come into contact with other parts within the appliance, damaging the cord and parts.

The present invention separates a cord connector to be attached to an electrical appliance into an adapter without a cord and a receptacle with a cord attached, screws the adapter onto the appliance, and then inserts the receptacle into the adapter and fixes it, unlike the conventional method. This makes it possible to eliminate defects.

Next, an embodiment of the present invention shown in the accompanying drawings will be described. Reference numeral 1 denotes a cylindrical receptacle consisting of a large diameter part 1a and a small diameter part 1b, an insulating plate 2 is fixed therein, an intermediate part of four male contacts 3 is fixed, and a cord 4 is connected to the rear end. A screw 1c is formed on the outer surface of the large-diameter tip portion 1a of the receptacle 1, and a retainer engagement ring groove 1d is formed on the outer surface of the intermediate portion.
A pull-out ring 5 is slidably fitted therein. 6
are a large diameter hole 6a and a small diameter hole 6 into which the receptacle is fitted.
An annular groove 6 is formed in the large diameter hole 6a with the adapter formed with the shape b.
The taper inner surface 7a of the retainer 7, which can be partially cut and expanded in the radial direction, is inserted into the retainer 7 with the large diameter portion facing forward, and a screw 6d is formed on the outer periphery of the rear end. 8 has four female contacts 1 on the internal insulating plate 9
0 is attached to the receptacle 1 with the connecting nut 11, and when the receptacle 1 is inserted into the adapter 6, the large diameter portion 1a is connected to the retainer 7.
The expanded retainer 7 is fitted into the retainer engagement ring groove 1d by its own elasticity and is locked integrally with the retainer 7. 12 and 13 are O-rings.

During use, when the extraction ring 5 that is connected as shown in FIG.
Since the retainer 7 comes into contact with point a and expands in the radial direction, it comes out of the retainer engagement ring groove, so when the adapter 6 is pulled, it comes off as shown in FIG. The screw 6d of the removed adapter 6 is screwed and fixed to the electrical appliance housing 14. 15 is pack king. Next, the cord 4 connected to the male contact 3 of the receptacle 1 is passed through the adapter 6 and inserted into the electrical appliance, and when the receptacle 1 is pressed into the adapter 6, the retainer 7 is fitted into the retainer engagement ring groove 1d as described above. will be stopped. When the female contact 10 of the plug 8 is inserted into the male contact 3 of the receptacle 1 and the plug 8 and the receptacle 1 are integrated with the connecting nut 11, they are connected as one body as shown in FIG. The tip of the cord 4 opens the lid of the appliance and screws into place.

According to the present invention, a cord connector is separated into an adapter without a cord attached and a receptacle with a cord attached, the two are press-fitted to form an integral body, and separated by sliding of a pull-out ring that is slidably fitted on the outer surface of the receptacle. Since the cord connector can be attached to an electrical appliance without twisting or rotating the cord, it is possible to prevent the cord from coming into contact with other parts in a small electrical appliance and damaging the cord and the parts.
