Specifically, in the automatic switching circuit 100 using the reed switch according to the second embodiment of the present invention, the lead wire 155 inside the reed switch 150 may be configured with the same polarity as the previous embodiment. Therefore, when a magnetic force is applied to the inside of the reed switch 150 by the magnet 250, the lead wires 155 inside the reed switch 150 are configured to have the same polarity, so that they are pushed together to block the movement of current. Can be.

In addition, when the magnet 250 is separated from the reed switch 150, that is, when the battery 201 is separated from the battery holder 200, the magnetic force formed between the lead wires 155 inside the reed switch 150 disappears and the lead wire is removed. Reference numeral 155 is returned to its original position by elasticity, and the returning shape is coupled between the lead wires 155 having the same polarity, so that the movement of the current may be performed. According to the present invention according to FIG. 12, the rechargeable battery holder 300 may be separately provided, and the rechargeable battery 301 may be freely mounted and removed. However, the rechargeable battery 301 may be formed in the present invention. .

FIG. 13 is a diagram illustrating an automatic switching circuit using a reed switch according to a modification of the second exemplary embodiment of the present invention.

In the automatic switching circuit 100 using the reed switch according to the modified example of the second embodiment of the present invention according to FIG. 13, the reed switch 150 may include the negative electrode (-) of the battery holder 200 and the rechargeable battery holder 300. It may be different from the second embodiment shown in FIG. 12 in that it is configured in the form of connecting the negative electrode (-).

Therefore, the other side of the reed switch 150 may be connected to the negative electrode (−) of the battery holder 200 and the negative electrode (−) of the power output terminal 700. In addition, one side of the reed switch 150 is connected to the negative electrode (-) of the rechargeable battery holder 300, the positive electrode (+) of the layer battery holder 300 and the positive electrode (+) of the battery holder 200 is a power output terminal It may be made of a configuration connected to the positive electrode (+) to (700).

14 is a view illustrating a process of driving a normally open (NO) type reed switch and an NC (normally closed) type reed switch of the present invention.

In FIG. 14, the dotted line represented around the magnet 250 represents the range of magnetic force for the preferred description of the present invention, and the range of the magnetic force that may affect the operation of the reed switch 150 is shown in FIG. Named. The reed switch 150 is a (NO, Normal Open) type reed switch 150a and a (NC, Normal Close) type reed switch 150b in a process in which a contact is opened and shorted after a magnetic force is applied. ) Can be separated. For the preferred description of the present invention will be described by referring to the N-type reed switch 150a according to the drawing (A), the NC-type reed switch 150b according to the drawing (B).

 The reed switch 150 according to the second exemplary embodiment of the present invention may be different from the EN type reed switch 150a of the first exemplary embodiment described with reference to FIG. 7B as the NC type reed switch 150b. It can be seen that the reed switch 150 according to FIG. 7 is configured such that the reed is magnetized with opposite polarity and attracted to each other. However, the NC-type reed switch 150b shown in FIG. 14 may be configured such that the lead wires 155 are magnetized to the same polarity and are pushed together after the magnetic force is transmitted by the magnet 250 to open the switch. have. In addition, since the contact of the left lead wire 155a and the right lead wire 155b is broken by magnetic force, the current of the reed switch 150 does not flow, and thus the switch may be opened. On the other hand, in the state in which no magnetic occurs, the left lead wire 155a and the right lead wire 155b are joined by elasticity, and thus a short circuit state in which current flows.

15 is a view showing a driving process of the reed switch switching circuit according to whether or not the battery is inserted in the second embodiment of the present invention.

For a better understanding of the invention according to the drawings it can be compared with the inventive form of the first embodiment represented in figure 8. Operation of the reed switch 150 according to FIG. 15 may also be configured to be determined depending on whether the battery 201 is inserted into the battery holder 200. According to FIG. 15A, when the battery 201 is not inserted into the battery holder 200, current may flow differently from the EN reed switch 150a described with reference to FIG. 8 of the reed switch 150. . On the other hand, when the battery 201 is inserted according to (B) of FIG. 15, the contact may be in an open state according to the polarity of the lead and thus may be in an open state in which no current flows.

FIG. 16 is a view illustrating a state in which an automatic switching circuit using a reed switch is driven according to whether a battery and a rechargeable battery are inserted in the second embodiment of the present invention.

For the description of the automatic switching circuit 100 using the reed switch according to the second embodiment of the present invention will be described with reference to (1a) the driving process of the automatic switching circuit 100 using the reed switch of FIG. In addition, as shown in FIG. 9, the drawings of (1a) and (2b) are divided into (A), (B), and (C) according to whether the battery 201 and the rechargeable battery 301 are inserted.

The driving process of the second embodiment of the present invention mainly described with reference to FIG. 16 is illustrated as (b) of FIG. 16. 1A and 2B of FIG. 16 differ in the type of the reed switch 150. First, 1a is an NO reed switch 150a. When magnetic force is transmitted to the reed switch 150, the lead wires 155 having different polarities are joined to each other so that the reed switch 150 is driven. In the NC (NC) reed switch 150b of (2b), when the magnetic force is transmitted to the reed switch 150, the lead wires 155 having the same polarity push against each other and the left lead wire 155a and the right lead wire ( 155b) may be broken.

Therefore, when comparing (A) of (1a) and (2b) of FIG. 16, the reed switch 150 of (1a) may be shorted to apply a current from the rechargeable battery holder 301 to the power output terminal 700. The reed switch 150 of 2b does not apply magnetic force to the lead wire 155 constituting the reed switch 150, that is, the magnet 250 is spaced apart from the reed switch 150 by a predetermined distance or more. 155 is configured in such a state that the original positions are not separated from each other to apply a current from the rechargeable battery holder 301 to the power output terminal 700.

Next, the driving of the reed switch 150 will be described by comparing (B) of (1a) and (2b). First, in the case of 1a, the reed switch 150 may be opened by spaced apart from the magnet 250 by a predetermined distance or more.

Therefore, the lead wires 155 having different polarities inside the reed switch 150 are not affected by the magnetic force, and are returned to their original positions due to the elasticity of the lead wires 155 themselves, which may cause the contact to be broken. . Accordingly, the reed switch 150 may be a current from the battery holder 201 to the applied power output terminal 700. On the other hand, in the case of (B) of (2b) in Figure 16, the transfer magnet 250 may be in contact with the inside of the reed switch 150 may apply a magnetic force. However, in FIG. 16, the lead wires 155 inside the reed switch 150 of 2b are configured to have the same polarity, and when the magnetic force is applied, the lead wires 155 having different polarities push against each other, thereby opening the switch. Can be. Therefore, the current may not be applied in the direction of the rechargeable battery holder 300 and the automatic switching circuit 100 using the reed switch may be in a state in which no current is applied from the battery 201.

The following will be described by comparing (C) of (1a) and (2b). In the case of (1a), as in (B), the transfer magnets are spaced apart and no magnetic force is applied. However, regardless of whether the rechargeable battery 301 is inserted or not, the automatic switching circuit using the reed switch of the present invention has a difference in driving process only when the battery 201 is inserted into the battery 201. Similarly, since the magnetic force is not applied to the inside of the reed switch 150, the lead wire 155 is not in contact with each other, so that a current cannot be applied.

On the other hand, in the case of (2b), the magnetic force is applied by the magnet 250, but when the magnetic force is applied, the lead wires 155 configured inside the reed switch 150 push each other by the same polarity, whereby the reed switch 150 There is a difference in that the current is configured to be blocked so that the current from the rechargeable battery 301 can not be transferred to the power output terminal 700.

When comparing the first embodiment 1a of the present invention illustrated in FIG. 16 with the second embodiment 2b of the present invention, there may be a difference in the switching process of the reed switch 150, but the battery 201 It is the same that it was invented for the purpose of preventing safety accidents and problems that can occur by using the rechargeable battery 301. Therefore, as in (C), in the case of (1a) and (2b), both the batteries 201 and the rechargeable battery 301 are configured to cut off the current flowing from the rechargeable battery holder 300 at the same time.

FIG. 17 is a view illustrating a state in which an automatic switching circuit using a reed switch is driven depending on whether a battery and a rechargeable battery are inserted in a modification of the second embodiment of the present invention.

(A) and (2b) of FIG. 15 are different in the kind of the reed switch 150. FIG. In the case of the second embodiment and the second embodiment of the present invention, when compared with the first and second embodiments of the automatic switching circuit 100 using the reed switch of the present invention shown in FIG. ) May be different from the connected position, the driving according to whether the rechargeable battery 301 and the battery 201 is inserted can be made in the same configuration.

For the preferred description of the present invention, as shown in Figure 16 (1a) may be made of a configuration using the NC (NO) reed switch 150a, (2b) NC (NC) reed switch 150b.

Therefore, in the case of 1a, when the magnetic force is transmitted to the inside of the reed switch 150, the lead wires 155 having different polarities are joined to each other so that the reed switch 150 is driven, and the magnetic force is the reed switch 2b. When delivered inside 150, the lead wires 155 having the same polarity may be pushed together and the junction between the left lead wire 155a and the right lead wire 155b may be broken.

In addition, in the case of (B) of FIG. 17 (1a), as in (B) of (16) of FIG. Magnetic force may not be applied. Similarly, in the case of (B) of FIG. 17 (2b), the lead wires 155 inside the reed switch 150 of (2b) of FIG. 16 are configured with the same polarity and lead wires 155 having different polarities when magnetic force is applied thereto. ) Are pushed together so that the switch can be blocked.

The following will be described by comparing (C) of (1a) and (2b).

In the case of (1a) of FIG. 17, as in the case of (1a) of FIG. 16, the automatic switching circuit 100 using the reed switch of the present invention has a difference in the driving process only when inserted into the battery 201. As in (B) of (1a), C) has no magnetic force applied to the inside of the reed switch 150, so that the lead wire 155 does not come into contact with each other, so that a current cannot be applied. The driving process of the modified embodiment of the automatic switching circuit using the reed switch according to the first and second modified embodiments of the present invention according to FIG. 17 is illustrated in FIG. 16. It can be seen that there is no difference from the second embodiment. However, the automatic switching circuit 100 using the reed switch according to the modified embodiment of the present invention can be seen that there is no difference in the driving process depending on whether the rechargeable battery and the battery are inserted.

On the other hand, in the case of 2b, the lead wire 155 inside the reed switch 150 is applied with magnetic force by the magnet 250, but when the magnetic force is applied, the lead wire 155 configured inside the reed switch 150 has the same polarity. By pushing each other by, the reed switch 150 is cut off accordingly, there may be a difference in that it is configured so that the current from the rechargeable battery 301 can not be transmitted to the power output terminal 700.

18 is a view showing a switching sequence of the automatic switching circuit using the reed switch when the battery is inserted.

Here, the open state of the reed switch 150 refers to a state in which the lead wire 155 provided inside the reed switch 150 returns to its original position by elasticity. The state in which the lead wire 155 is returned to its original position by elasticity is achieved because the magnetic force of the magnet 250 provided inside the battery holder 200 does not reach the reed switch 150 in the process of inserting the battery 201. Can lose. This is described based on the first embodiment of the present invention having the EN type reed switch 150a, and the automatic switching circuit 100 using the reed switch is provided with the NC type reed switch 150b. In the case of the second embodiment, the step (S18-3) of opening the reed switch 150 when the battery 201 is inserted (S18-3) is that the magnetic force of the magnet 250 provided in the battery holder 200 of the reed switch 150 The lead wire 155 may be transferred to the component and be opened. However, regardless of the modifications of the first embodiment, the second embodiment, and / or the first embodiment, and the modification of the second embodiment, the switching order when the battery 201 is inserted may be performed in the same order.

This is described with reference to the first embodiment of the present invention having the end switch 150a.

On the other hand, when the automatic switching circuit 100 using the reed switch includes the NC type reed switch 150b, the magnet 250 provided inside the battery holder 200 is the reed switch when the battery 201 is removed. It may be made in a state that does not transmit the magnetic force to the 150, that is, the reed switch 150 is not received the magnetic force from the magnet 250, so the lead wire 155, which is a component inside the reed switch, is originally caused by elasticity. The short circuit can be made by returning to the position of. Although the process of shorting may be different, the order of switching when the battery 201 is removed regardless of the modifications of the first and second embodiments and / or the first and second embodiments is the same order. Can be done with.
