Switch concent be improved shape of terminal

The present invention relates to a recessed switch outlet used by connecting a plug in a home or office, and more particularly, a switch outlet that simplifies the structure and improves electrical contact performance by improving the shape of the grounding terminal and the connecting terminal. It is about.

In general, at a predetermined position on the wall or floor of a building indoors, such as homes and offices, a power outlet and a communication outlet are separately installed so that various electric devices can be used or communication such as a telephone or the Internet can be performed.

The recessed outlet has a form in which the plug can be inserted into the indoor wiring while being inserted into the wall of the indoor to connect the plug used indoors in the indoor wiring of electricity.

On the other hand, most users of electronic products are mainly using ON / OFF only the power switch without removing the plug directly because of the inconvenience and hassle of using when the power supply of the electronic product is cut off.

In fact, when the user pulls out the plug directly, the user often pulls the wire without holding the plug body. Therefore, there is a safety risk due to damage to the wire or an electric shock.

To solve this inconvenience, outlets of various structures have been developed to enable self-power adjustment.

For example, Korean Patent Publication No. 10-0733492 discloses an embedded outlet with a switch.

The plug-in switch outlet is connected to the "+" power line and the "-" power line to the outlet and the switch, respectively, and the ground wire to the outlet and the switch connected to the power line, respectively, It consists of a form that can be supplied and cut off by the operation of the switch.

Therefore, the power can be cut off only by switching off the switch even when the plug is not removed from the outlet. In addition, most homes, offices, apartments, etc. have recently used recessed switch outlets because the power can be cut off by only switching on the switch. There is a trend.

However, in the case of a conventional recessed switch outlet, in the case of a ground terminal for grounding, it is composed of three parts, that is, a terminal body, a plug side terminal, and an earth wire side terminal, and these are connected and assembled by screw fastening and soldering, respectively. It has the following disadvantages in that it is in the form.

First, the number of parts constituting the grounding terminal is disadvantageous in terms of assembly workability, such as screw fastening or soldering of a large number of terminals one by one during assembly, and the manufacturing cost is also increased to reduce the product competitiveness There are disadvantages.

Second, since each terminal is connected in the form of screw connection and solder connection, there is a high possibility of being easily deformed when heat generated by contact resistance. The disadvantage is that it is vulnerable.

In addition, in the case of the conventional recessed type switch outlet, since the terminals of both sides are formed in a circular shape by simply molding the terminals on both sides, the electrical contact performance with the plug is not good, and for a long time, When used, the durability is significantly reduced, there is a problem of a very high risk of fire due to poor contact.

Therefore, the present invention has been devised in view of such a point, and by implementing a new integrated ground form in which the main body of the ground terminal, the plug side terminal, and the earth wire side terminal are integrated into one unit, the number of parts and the structure are simplified. The purpose of the present invention is to provide a switch outlet having an improved terminal form that can improve assembly performance and significantly lower manufacturing costs.

In addition, the present invention implements a new type of connection terminal structure in which an elastic tension contact method is introduced to the connection terminal in contact with the plug, thereby improving the electrical contact performance between the connection terminal and the plug, and thus the connection function. It is another object of the present invention to provide a switch outlet having an improved terminal shape that can achieve stabilization of the terminal and improve durability of the terminal.

One example of a switch outlet having an improved terminal shape provided by the present invention to achieve the above object includes a ground terminal for the conduit ground and a connection terminal for a positive connection, while the ground terminal is the outlet length direction A terminal body that is elongated, a plug side terminal which is integrally extended from the terminal body and is bent 90 ° in an upward direction, and an earth line side terminal which is integrally extended from the terminal body and is bent 90 ° in a downward direction. Characterized in that made.

Here, in the case of the ground terminal, the plug-side terminal is formed to extend integrally from the terminal body, and the plug-side terminal at this time includes a first vertical terminal having a shape in which the end of the terminal body is vertically bent at a predetermined length, and the terminal. It is preferable to comprise the 2nd vertical terminal of the form which bent vertically, after cut | disconnecting the center part of a main body elongately.

In addition, another example of a switch receptacle having an improved terminal form provided by the present invention for achieving the above object includes a ground terminal for a conduit ground and a connection terminal for a positive connection, while the connection terminal is a connection line. It consists of a terminal body including a connecting piece for connecting and a connecting piece to which the plug is fitted, wherein the connecting piece extends integrally from the upper end of the terminal body and consists of a pair of vertical pairs parallel to each other and at the same time an arc for accommodating the plug at each end. (Iii) the plug contact portions are formed to face each other, so that both plug contacts can be contacted while elastically compressing the plug circumferential surface as the plug is inserted into the plug contact portion.

 Here, in the case of the plug contact portion in the connecting piece of the connecting terminal it is preferable to have a tapered shape that the gap becomes narrower from the top to the bottom to improve the contact performance with the plug.

The switch outlet having an integrated ground terminal and an elastic connection terminal provided by the present invention has the following advantages.

First, since the grounding terminal is composed of the terminal body, the plug side terminal, and the earth line side terminal, the number of parts can be greatly reduced, and the structure can be simplified. As a result, it is inconvenient to fasten several terminals as before. It is possible to improve workability at the time of assembly, such as to solve the problem, and can significantly reduce the manufacturing cost.

Second, the plug detachability is excellent by securing the shape retaining force by the self-tension of the plug-side terminal integrated with the terminal main body, and there is an advantage that deformation does not occur when heat is generated by contact resistance.

Third, in the case of the plug-side terminal has a gently bent form, it has excellent contactability, and excellent electric shock protection and connection device protection.

Fourth, the electrical contact performance between the connection terminal and the plug can be improved by including an arc-shaped plug contact portion in which the connection terminal exhibits elasticity characteristics.

Fifth, since the plug contact portion of the connection terminal is elastic, the connection function can be stabilized even at frequent contact with the plug, and the durability of the terminal can be improved.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Can improve the contact performance.

In particular, the arc-shaped plug contact portion 24 is formed in a tapered shape that the gap is narrowed from the top to the bottom, so that when the plug is fully inserted, the plug is in close contact with the plug contact portion 24 as a whole Of course, it is possible to ensure a more intimate state by the crimping force exerted on the lower portion of the plug contact portion 24, and eventually to improve the electrical contact performance.

Also, when the connecting piece 23 is integrally formed from the boundary portion between the terminal body 21 and the connecting piece 23, that is, from the terminal body 21, a cutout portion 25 is formed at the first starting portion. As a result, the tensioning action of the connecting piece 23 can be further enhanced.

As such, the connection terminal has an arc-shaped plug contact portion and is elastically connected to the plug using both vertically parallel connecting pieces along the direction in which the plug is fitted, thereby making electrical contact between the connection terminal and the plug. The performance can be improved, and, as a result, the durability of the terminal can be increased as well as stabilization of the connection function of the connection terminal.
