At this time, in the case of the embodiment according to the present invention, but not shown in detail, if necessary to fix the wire inserted into the inside using a fixing means such as a screw or to form a structure that does not fall off once inserted into a projection on the inner peripheral surface It is preferable.

In addition, the input line connector 32 and the pair of distribution line connector 33 is preferably formed of a conductor such as metal so that electricity can flow well.

The connecting portion 43 of the switching device 40 is movably inserted into the connecting portion hook hole 32a formed at the upper end of the input line connecting port 32.

Therefore, since the input line connector 32 having the fixed input line L1 is always connected through a pair of distribution line connector 33 and the connection portion 43 having the distribution line L2 fixed thereto, stable electrical connection can be realized. have.

The shot piece 34 is a conventional leaf spring.

In addition, the first and second current detection sensors 50a and 50b are disposed on upper surfaces of both sides of the case 31 and detect whether or not current flows, and output a detection signal.

At this time, the first and second current detection sensors 50a and 50b are conventional ammeters.

On the other hand, the control unit 60 is installed on the plate 1, the control signal output from the first and second current detection sensors (50a, 50b) to control the confirmation light 70 provided on the plate (1). . In more detail, in the present embodiment, when the detection signal is input from the first current sensor 50a, the controller 60 turns on the light bulb at the confirmation light 70, that is, the A portion, and vice versa. When the detection signal is input from the current detection sensor 50b, the control unit 60 turns on the light bulb 70, that is, the B part, to inform the worker of the current state.

And, when both the A and B bulbs of the confirmation light 70 is not lit, the operator presses the motor operation switch 80 installed on the plate 1 in the upward or downward direction, so that the switching device 40 By operating the drive motor 41, the electrical connection can be switched.

Referring to the operation of the present invention made of the configuration as described above are as follows.

As shown in FIG. 3, the input line L1 and the power distribution line L2 are respectively connected to the input line connecting port 32 and the pair of distribution line connecting ports 33.

Electricity flowing along the input line L1 is connected to the distribution line connecting port 33 located on the left side through the connecting portion 43 and flows along the distribution line L2.

At this time, the first current detection sensor 50a located on the upper left side of the case 31 detects electricity flowing through the distribution line connecting port 33 located on the left side and transmits a detection signal to the controller 60. The controller 60 receives the detection signal from the first current sensor 50a to control the operation of the A bulb of the confirmation lamp 70.

Therefore, the operator can intuitively recognize that the electricity flows smoothly through this.

On the other hand, when both the A and B bulbs of the confirmation lamp 70 is not lit, as shown in Figure 4, the operator moves the motor operating switch 80 installed on the plate 1 in the upward or downward direction. Press to operate the drive motor 41 of the switching device 40.

The drive motor 41 operated by the motor operation switch 80 forcibly rotates the screw 41a connected to one side, and the transfer block 42 connected to the screw 41a is left along the guide part 31a. Will move from right to right.

At this time, the connection part 43 fixed to the lower end of the transfer block 42 is moved from left to right and finally inserted into and fixed to the distribution line connector 33 inserted and fixed to the right side.

By being connected as described above, the electricity flowing along the input line (L1) is connected to the distribution line connector 33 located on the right side, and the electricity flows along the distribution line (L2) finally inserted and fixed to the right distribution line connector (33). .

At this time, as mentioned above, at this time, the second current sensor 50b located on the upper right side of the case 31 detects the electricity flowing through the distribution line connection port 33 located on the right side to send the detection signal to the controller 60. To pass.

The controller 60 receives the detection signal from the second current sensor 50b to control the B bulb of the confirmation lamp 70.

Therefore, the operator can intuitively recognize that the electricity flows smoothly through this.

In addition, the above-described configuration is a basic premise, and connection inducing means are further provided at both ends of the connecting portion 43 so as to eliminate connection defects of the connecting portion 43 and maintain a safe, smooth and accurate connection state.

In particular, the connection guide means are equally provided at both ends of the connection portion 43.

And, in order to connect the connection guide means to the connection portion 43, both end surfaces of the connection portion 43 is formed with a connection groove 130 is formed with a screw thread on the inner circumference.

Here, the coupling rod 100, the elastic spring 110, the connection piece 120 should all have a conductivity, it is preferably formed of silver or copper so as to reduce the heat loss is low resistance when energizing.

In addition, the coupling rod 100, the elastic spring 110, the connecting piece 120 should have a size smaller than the diameter of the connector 43, which is the coupling rod 100 when the connector 43 is moved, When the elastic spring 110 and the connecting piece 120 are inserted into the distribution line connecting port 33, the elastic spring 110 and the connecting piece 120 are smoothly inserted so as to guide the correct connection work.

In addition, the connection piece 120 is more preferably configured to minimize the contact failure by having a slightly moon-shaped convex outward to have a slight elasticity.

On the other hand, the heater mounting groove 200 is recessed in the form as shown in Figure 5 (b) in the front lower side of the mounting table 20 fixed inside the enclosure (10).

In addition, a relatively inexpensive glass tube heater 210 is installed in the heater installation groove 200, and in order to reduce heat loss and increase drying effect, a semi-circular heat reflection plate 220 is first installed in the heater installation groove 200. After the glass tube heater 210 is fixed to be installed at intervals with the heat reflection plate 220.

Then, the wire drawn out from the glass tube heater 210 is connected to the control unit 60 to control the heating operation.

In addition, the temperature sensor 230 and the humidity sensor 240 are installed on the upper sides of both sides of the mounting table 20, respectively.

In addition, the temperature sensor 230 and the humidity sensor 240 are electrically connected to the control unit 60, respectively.

Such a configuration further includes pressurized contact using the elastic deformation force of the connecting piece 120 and the elastic spring 110 when the connecting portion 43 is transferred by the ball screw to switch the connection with the power distribution line L2. The structure prevents connection failure.

In addition, when the condensation phenomenon occurs due to the temperature difference inside the enclosure 10 or the humidity inside the enclosure 10 becomes higher than a certain level due to moisture, moisture, or the like introduced through a fine gap, the controller 60 from the humidity sensor 240. After transmitting the measured signal, the glass tube heater 210 is operated to quickly dry the interior until the temperature detected by the internal temperature, that is, the temperature sensor 230 is greater than or equal to the predetermined temperature, and the drying is completed, and the predetermined temperature is completed. If abnormal, the glass tube heater 210 is turned off so that the interior of the enclosure 10 can be maintained at a constant dryness at all times.

Through this, it is possible to prevent the risk of short circuit or short circuit in the enclosure 10 in advance.
