Description

{THE STRUCTURE OF TIMER CONTAINER CONNECTING WITH ELECTRIC WIRE}

The present invention relates to a structure of a power line connecting end of a timer housing for storing and fixing a timer, and directly outputs input power when the set time of the timer is on in an output power line connecting end structure of the timer housing. If there is a need of the user to be applied to the load side by using the power supply, the input power output connecting member having a shape corresponding to the guide groove shape formed on the outer circumferential surface of the housing is stored in the guide groove so as not to protrude above the housing surface By providing a configuration that enables the connection of the electrical path between the predetermined terminals, the electrical connection work is made safe and convenient, and the operator's insulator is coated with an insulating material on the surface where the connection member for input power output is in contact with air. For preventing electric shock and preventing interference from the external environment The.

In general, the analog timer has a configuration in which the hour hand, minute hand, second hand, and operation time setting plate are connected to each other through a plurality of connection gears having a movement part inside and gear-coupled to the movement driving gear.

In addition, the analog timer is commercialized in various forms such as a DIN rail or a wall mountable form or a form configured to be individually accommodated in each product, and a power line input to such an enclosure and applied to the analog timer. The output power line is coupled to the output power line according to the on / off operation of the timer.

In general, the analog timer has a 5-terminal type, and the 5-terminal configuration is generally designated as ①, ②, ③, U1, and U2 from the left side, where the terminals marked U1 and U2 are applied to the timer side. Input power line connection terminal for connecting phase and T phase power, and terminals marked ①, ②, ③ are A contact terminal, COMMON terminal and B contact terminal, and power output from timer is ① It is used by connecting to terminal and ③.

In such a conventional timer housing, the input power may be drawn out as it is from the load side when the timer is set on. In such a case, the output line may be connected to a terminal different from the terminal normally used. In this case, the necessary connection terminals are ② and U1 terminals.

In other words, in order to output the input power input to the timer side as it is to be output to the load side, by separating the upper case of the timer housing and coupled to the ② and U1 terminal side bolts using a single wire or stranded wire separately from the inside of the housing. Or by connecting the cable between ② and U1 terminals at the lower position of the enclosure without disconnecting the upper case, or for such a case, separately Additional methods of configuration are also used.

However, these methods all involve at least one or more problems. First, the first method has to be inconvenient to separate the upper case of the enclosure, so that the electrical insulation is completely performed in a limited space inside the enclosure. It is difficult to connect the wires. The second method is to cause an explosion due to a short circuit when the insulation of the power cable is excessively peeled off or even a single minute power wire in the stranded wire is exposed to the outside and contacts other power terminals. Although the third method is the safest method of electrical connection, it is difficult to achieve a configuration for adding two additional terminals and isolating the additional terminals from other terminal parts within a limited enclosure size and manufacturing cost. There is a problem that rises.

The present invention is conceived to solve the problems as described above, an object of the present invention is to provide a safe and convenient configuration that can draw the input power directly to the output power from the load side in the timer housing structure.

Another object of the present invention is to provide a configuration that can be connected most economically without a large structural change when providing a configuration that can draw the input power directly to the output power from the load side in the timer housing structure.

Other objects of the present invention will be described in more detail in the structures and operations described below.
