Description

[Detailed Description of the Invention] This invention relates to an intermediate switch or an intermediate switch with an outlet that can be used as an intermediate switch or a table tap as desired.

Traditionally, the intermediate switch used for electric kotatsu simply turns the power on and off, and if you want to use electric appliances such as a desk lamp, electric kettle, or electric cooker on the kotatsu board, you have to connect the power separately from a wall outlet. Therefore, the cord often gets in the way, and if the cord of the appliance is short, an additional connecting cord must be used, which is troublesome.

To overcome this drawback, simply providing an outlet at the intermediate switch will cause the cord to generate heat as a result of an overload current flowing through the cord that is greater than the allowable current when the electric kotatsu and electric appliance are used at the same time.

This invention is an improvement based on the above points, and its purpose is to be able to supply power from the intermediate switch to the electric appliances placed on top of the electric kotatsu, and to reduce the heat generated by the cord. The goal is to provide an intermediate switch with a safe outlet that prevents this.

An embodiment of this invention will be described below with reference to FIGS. 1 to 5. Reference numeral 1 denotes a container body 4 having a pair of plug blade insertion holes 2, 2 and a long hole 3 on the front side;
It consists of a lid body 5 that is combined with the vessel body 4, and is integrally connected with a connecting screw 6.

One of the power terminals 7 and the load terminals 8 which are attached to the container 1 is attached to the container body 4 using a single terminal plate with rivets 9.
The other power terminal 7' and the load terminal 8' are separated from each other and connected to the stud 1.
It is fixed on the vessel body 4 at points 0 and 11. The power cord 12 is inserted through the power supply side opening 13 of the container 1 and connected to the power supply terminals 7, 7' by terminal screws 14, 14, and the load cord 15 is inserted through the load side opening 16 on the other side of the container 1. through the load terminals 8, 8'
The terminals are connected to each other by terminal screws 17, 17. X is a switch mechanism, which is built into the container 1 with its upper part protruding from a long hole 3 provided in the container body 4, and has a door 13a so as to open and close between the separated power supply terminal 7' and load terminal 8'. a handle 16 integrally provided with a handle 16; a movable contact plate 19 supported reversibly while being electrically connected to a load terminal 8';
It consists of a coil spring 20 interposed between the lower end of the handle 18 and the movable contact plate 19. Reference numeral Y denotes an outlet, which is composed of blade receiving springs 21 and 22 provided at both power terminals 7 and 7, and a plug blade insertion hole 2 is provided in the container body 4 in correspondence with the blade receiving springs 21 and 22.

As shown in FIGS. 3 to 5, when the handle 18 is positioned on the right side, the contact point of this intermediate switch with outlet is turned off, and as shown in FIG. The plug blade 21 can be inserted into the outlet Y, and this intermediate switch with an outlet functions as a table tap. Next, when the handle 18 is slid to the left to turn on the contact in order to supply power to the electric kotatsu 23, the handle 18 is turned on as shown in FIG.
The door 18a provided in the plug plug 21 closes the plug blade insertion hole 2, so that the plug blade of the plug 21 for supplying power to the electric appliance Z cannot be inserted into the outlet Y, and this intermediate switch with a power outlet functions as an intermediate switch. Therefore, the electric kotatsu 23 and the electric appliance Z are never used at the same time, and no overload current larger than the allowable current flows through the power cord 12.

As described above, this invention is based on the power terminals 7, 7' for connecting the power cord 12, the load terminals 8, 8' for connecting the load cord 15, and the switch for opening and closing between the power terminals 7' to 8'. It consists of a mechanism Since it is integrated, it is possible to supply power from the intermediate switch to the electric appliance Z placed on the electric kotatsu 23, and the intermediate switch or table tap can be used as desired. A safe intermediate switch with an outlet in which overload current does not flow through the cord 12 and heat generation of the cord 12 is prevented can be obtained.
