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

[Fig. 1] is an exemplary diagram of a state in which a disconnection detection type junction box for a wireless power track according to the present invention is installed, and [Fig. 2] is a disconnection detection type junction box for a wireless power track according to an embodiment a of the present invention. is an exemplary view schematically showing, and [Fig. 3] is an excerpt of a part of [Fig. 2], and is an exemplary view showing the case where the track core in the track cable operates normally and when some of the track core wires are disconnected and [Fig. 4] is a view showing a plurality of embodiments in which the ring core member of the present invention is installed on the track core in the track cable, and [Fig. 5] is a plurality of ring core members constituting the present invention It is a view showing another embodiment installed on the track core in the track cable.

The present invention is a disconnection detection type junction box for a wireless power track. As shown in [FIG. 1], an inverter 10 and a plurality of core wires form a closed circuit based on the inverter 10, and power is supplied from the inverter 10. The receiving track cable 20, the inverter 10 and the extension cable 30 interconnecting the track cable 20, and the inverter 10 and the extension cable 30 and the track cable 20 are sequentially passed through It is configured to detect the disconnection of the track cable 20 in a state in which the extension cable 30 and the track cable 20 are interconnected in an automatic distribution system having a heat-sensitive wire 40 disposed thereon.

To this end, the disconnection detection type junction box for a wireless power track according to the present invention includes a first core wire junction member 110, a second core wire junction member 120, ring core members 130 and 130', and a disconnection detection member ( 140) may be included.

The first core wire junction member 110 includes a first track core wire 21 composed of a plurality of core wires positioned at one end of the track cable 20 adjacent to the extension cable 30 as shown in FIG. The first extended core wire 31 composed of a plurality of core wires disposed on the extension cable 30 to correspond to the first track core wire 21 is connected to each other so as to conduct electricity.

Here, since the first core wire junction member 110 is connected to the first track core wire 21 and the first extended core wire 31 through the lug members 111 and 112 as shown in FIG. 2 , resistance increases and fastening There is a burden of overheating due to a defect.

The second core wire junction member 120 includes a second track core wire 22 and a second The second extended core wire 32 composed of a plurality of core wires disposed on the extension cable 30 corresponding to the track core wire 22 is connected to each other so as to conduct electricity.

Here too, since the second core wire junction member 120 is connected to the second track core wire 22 and the second extended core wire 32 through the lug members 121 and 122 as in [FIG. 2], resistance increase and fastening There is a burden of overheating due to a defect.

On the other hand, referring to [Figs. 2] and [Fig. 4], the track cable 20 includes the first track core wire 21 and the second core wire junction member 110 and the second core wire junction member 120 based on the first core wire junction member 110 and the second core wire junction member 120. It is necessary to look at the arrangement structure of the track core wire 22 .

For example, among the two lug members 111 provided in the first core wire junction member 110 of FIG. 2 , the first track core wire 21 connected to the lug member 111 positioned above the second core wire junction The second track core wire 22 connected to the lower lug member 121 among the two lug members 121 provided in the member 120 is paired to conduct electricity.

And, among the two lug members 111 provided in the first core wire junction member 110 of FIG. 2 , the first track core wire 21 connected to the lug member 111 positioned below the second core wire junction The second track core wire 22 connected to the upper lug member 121 among the two lug members 121 provided in the member 120 is paired to conduct electricity.

As a result, as in [Fig. 2] and [Fig. 5], one or more ring core members 130 and 130' are provided, so that the first track core wire 21 and the It may be arranged over the two track core wires 22 at the same time.

That is, the ring core members 130 and 130' include a first selected core wire and a second track core wire 22 composed of one or more core wires selected from among the first track core wires 21 as in [FIG. 2] and [FIG. 5]. ), which is arranged in the form of bundling the second selective core wire composed of one or more core wires selected from among them, and generates magnetic flux from the current of the first selective core wire and the second selective core wire through which current flows in opposite directions.

Here, the magnetic flux generated from the ring core members 130 and 130' generates an induced current in the conducting wire (eg, the secondary side) wound around the ring core members 130 and 130'.

At this time, the core wires having the direction of the current flowing through the first track core wire 21 and the direction of the current flowing through the second track core wire 22 opposite to each other are selected and bundled with the corresponding ring core members 130 and 130 ′.

And, referring to [Fig. 1] and [Fig. 2], each of the core wires extending from the first track core wire 21 and the second track core wire 22 is the first core wire junction member 110 and the second core wire junction member. When viewed with reference to (120), it forms a seamless line shape.

For example, one core wire extending from the first track core wire 21 on [FIG. 2] is in the form of a line to the second track core wire 22 on [FIG. 2] along the track cable 20 closed circuit in [FIG. 1] is extended to

As a result, when looking at the core wires surrounded by the ring core member 130 , the core wire on the first track core wire 21 side and the core wire on the second track core wire 22 side are core wires of different lines, and currents in opposite directions are generated from each other. will flow

On the other hand, in [Fig. 2], the first track core wire 21 of the track cable 20 fitted into the ring core member 130 and the second track core wire 22 of the track cable 20 fitted into the ring core member 130 in [Fig. are the same number and because current flows in opposite directions, the magnetic flux generated in the member in the ring core member 130 is formed in the opposite direction as in [FIG. An induced current does not flow in the wire connected to the disconnection detecting member 140 in a state wound around the ring core member 130 as shown in FIG.

The disconnection detection member 140 is electrically connected to one or more ring core members 130 and 130 ′ as shown in FIGS. 2 and 5 , and is induced in one or more ring core members 130 and 130 ′. It is configured to determine whether one or more of the core wires corresponding to any one or more of the one or more ring core members 130 and 130' are disconnected by individually sensing the induced current.

That is, the disconnection detecting member 140 is an induced current generated by magnetic flux induced from the first track core wire 21 fitted inside the ring core member 130 and the ring core member 130 as shown in FIG. 2 . ) to individually sense the induced current generated by the magnetic flux induced from the second track core wire 22 fitted inside the.

By the way, as in [Fig. 2], the number of the first track core wires 21 and the number of the second track core wires 22 respectively fitted inside the ring core member 130 are the same, and the ring core member 130 ), since the current direction of the first track core wire 21 and the current direction of the second track core wire 22 are opposite to each other, the magnetic flux generated in the ring core member 130 will all be canceled.

On the other hand, as in [Fig. 2] and [Fig. 5], the same number of the first track core wire 21 and the second track core wire 22 provided in the track cable 20 is the ring core members 130 and 130'. When currents in opposite directions flow in the state sandwiched therein, the magnetic flux formed in the ring core members 130 and 130' is all canceled, and the conductor wire connected to the disconnection detecting member 140 in [Fig. 2] and [Fig. 5] In order not to form an induced current in the ring core member (130, 130') is preferably configured in the form of a circular or elliptical closed loop as shown in [Fig. 2] and [Fig. 5].

Here, the fact that an induced current is not generated in the wire connecting the ring core members 130 and 130' and the disconnection detecting member 140 in the states of [Fig. 2] and [Fig. 5] is shown in Fig. 3 (a). This means that disconnection does not occur in the first track core wires 21 and the second track core wires 22 fitted in the same number to the ring core members 130 and 130' in the same state.

However, the generation of induced current in the wire connecting the ring core members 130 and 130' and the disconnection detecting member 140 in the states of [Figs. 2] and [Fig. It means that the disconnection occurred in any one of the first track core wires 21 and the second track core wires 22 fitted in the same number of the ring core members 130 and 130' as shown in FIG.

3(b) shows a case in which one of the first track core wires 21 of the track cable 20 inserted into the ring core member 130 is disconnected.

Here, the ring core member 130' may be provided in plurality as shown in [Fig. 5], and the first track core wire 21 and the second track core wire 22 fitted to the ring core member 130' are It is preferable to keep the same number of each.

As described above, referring to [Fig. 1] and [Fig. 2], each of the core wires extending from the first track core wire 21 and the second track core wire 22 is the first core wire junction member 110 and the second core wire When viewed with reference to the core wire junction member 120, it forms a seamless line shape.

For example, one core wire extending from the first track core wire 21 on [FIG. 2] is in the form of a line to the second track core wire 22 on [FIG. 2] along the track cable 20 closed circuit in [FIG. 1] is extended to

As a result, when looking at the core wires surrounded by the ring core member 130 , the core wire on the first track core wire 21 side and the core wire on the second track core wire 22 side are core wires of different lines, and currents in opposite directions are generated from each other. will flow

On the other hand, preferably, the same number of the first track core wires 21 and the second track core wires 22 passing currents in opposite directions to each other as in (a) and [Figure 2] of [Fig. It may be configured to fit into the member 130, but in some cases, as in (b) and (c) of [Fig. 4], the ring core member 130 is the first track core wire 21 or the second track core wire. (22) may be fitted only.

For example, as in (b) of [Fig. 4], either one of the first track core wire 21 and the second track core wire 22 (eg, the second track core wire) In the case of selecting only the ring core member 130, there will be an advantage that it is not necessary to distinguish between the core wires inserted into the ring core member 130.

Here, in the case of (b) of [Fig. 4], magnetic flux is generated in the ring core member 130 only when the track cable 20 is not disconnected and in a normal state, so that the disconnection detecting member 140 and the ring core member 130. An induced current is generated in the wire connecting 140 may be configured to sense.

In the case (c) of [Fig. 4], as in Fig. 4(b), the core wire inserted into the ring core member 130 is selected from either the first track core wire 21 or the second track core wire 22. If only one side (eg, the second track core wire) is selected, there will be an advantage in that it is not necessary to distinguish the core wire inserted into the ring core member 130 .

However, in the case of (c) of [Fig. 4], as in the case of (a) of [Fig. 4], since the current passing through the ring core member 130 is in the opposite direction, the core wires of the track cable 20 are not disconnected. In a normal state, no current is induced in the conductor (eg, the secondary side) connecting the ring core member 130 and the disconnection detecting member 140, and if any one of the core cables of the track cable 20 is disconnected, the secondary conductor The current will be induced and the disconnection detecting member 140 may be configured to detect such a change in the induced current.

On the other hand, in order to detect heat in the automatic distribution system, the schematic configuration of the automatic distribution system is as follows through [Fig. 1] and [Fig. 2].

First, as the track cable 20 is arranged in the form of a track on the balance movement path of the automatic distribution system, power is wirelessly supplied to the cart moving along the track cable 20.

To this end, the track cable 20 is connected to the inverter 10 as shown in [Fig. 1] to receive power from the inverter 10.

And, the track cable 20 is not directly connected to the inverter 10, but is electrically connected to the inverter 10 through the extension cable 30 as in [Fig. 1], and the track cable 20 and the extension cable 30 ), the track cable 20 and the extension cable 30 are interconnected as shown in [FIG. 1] with the junction box according to the present invention disposed between them.

Such a junction box is a so-called terminal block in the process of interconnecting the core wires 21 and 22 of the track cable 20 and the core wires 31 and 32 of the extension cable 30, as in [Fig. 2], the core wire junction member ( 110 and 120) are provided.

And, the core wire junction members 110 and 120 may be provided with a screw fastening method for fixing the respective core wires 21, 22, 31, 32 to the core wire junction members 110 and 120, as shown in [Fig. 2]. A plurality of lug members 111 , 112 , 121 and 122 may be provided.

At this time, as in [Fig. 2], the screw fastening of each core wire 21, 22, 31, 32 is fixed to the core wire junction member 110, 120, or the lug member 111, 112, 121, 122 is compressed. As a result, the resistance value may increase, and there is a risk of fire due to the generation of heat.

The thermal wire 40 may be sequentially disposed via the inverter 10 , the extension cable 30 , and the track cable 20 with reference to FIGS. 1 and 2 .

Preferably, the heat-sensitive wire 40 constitutes a closed circuit in which two core wires are independently coated and arranged side by side. That is, each of the core wires arranged side by side on the heat-sensitive wire has a configuration in which current flows independently of each other normally.

In this way, when current flows independently of each other in each of the core wires provided in the heat-sensitive wire 40 and heat is generated in a portion adjacent to the heat-sensitive wire 40, the coated portion of each core wire melts and as a result, each of the core wires arranged side by side A short circuit occurs in which the core wires stick together.

If the short-circuit characteristic of the heat-sensitive wire 40 is utilized as described above, it can be detected whether heat is generated in the area where the heat-sensitive wire 40 is disposed through the current flowing through the heat-sensitive wire 40 and the amount of change in the resistance value corresponding to the current. have.

Here, since the heat-sensitive wire 40 is arranged for a very long time sequentially via the inverter 10, the extension cable 30, and the track cable 20, when a short occurs in the heat-sensitive wire 40, the heat-sensitive wire ( 40) and it is very important to be able to check where the short circuit occurred in any configuration adjacent to it.

To this end, the first embodiment of the present invention provides a first heat-sensitive wire junction member 310, an auxiliary heat-sensitive wire member 410, and a second heat-sensitive wire junction member 320 as shown in FIGS. 2 and 5. , a third heat-sensitive wire junction member 330 may be further included.

The first heat-sensitive wire junction member 310 has a first track feeling disposed in the track cable 20 corresponding to the first track core wire 21 among the heat-sensitive wires 40 as shown in FIGS. 2 and 5 . A structure in which one end of the heating wire 41 and one end of the first extended thermal wire 51 disposed in the extension cable 30 corresponding to the first extended core wire 31 of the thermal wire 40 are connected to each other so as to conduct electricity with each other. accomplish

The auxiliary heat-sensitive wire member 410 is disposed so as to be in contact with the outer surfaces of the first core wire junction member 110 and the second core wire junction member 120 as in [Fig. 2] and [Fig. 5], and the first core wire junction member (110) or the second core wire junction member (120) responds to heat generation.

To this end, the auxiliary heat-sensitive wire member 410 may constitute a closed circuit in which two core wires are independently coated and arranged side by side. That is, each of the core wires arranged side by side on the auxiliary heat-sensitive wire member 410 normally flows independently of each other.

In this way, when current flows independently of each of the core wires provided in the auxiliary heat-sensitive wire member 410 and heat is generated in a portion adjacent to the auxiliary heat-sensitive wire member 410, the coated portion of each core wire melts as a result. A short-circuit phenomenon occurs in which each core wire arranged side by side sticks to each other.

When the short characteristic of the auxiliary heat-sensitive wire member 410 is utilized as described above, the area in which the auxiliary heat-sensitive wire member 410 is disposed is measured through the current flowing through the auxiliary heat-sensitive wire member 410 and the amount of change in the resistance value corresponding to the current. The presence of fever may be detected.

As such, as the auxiliary heat-sensitive wire member 410 is disposed to contact the outer surfaces of the first core wire junction member 110 and the second core wire junction member 120 as shown in FIGS. 2 and 5 , the first When heat is generated in the core wire junction member 110 and the second core wire junction member 120, as the auxiliary thermal wire member 410 is shorted, the external heat sensing control member (not shown) is connected to the first core wire junction member 110 ) or the second core wire junction member 120 can be seen that heat is generated.

The second heat-sensitive wire junction member 320 has a second track feeling disposed in the track cable 20 corresponding to the second track core wire 22 of the heat-sensitive wire 40 as shown in [Figures 2] and [Figure 5]. One end of the heating wire 42 and one end of the auxiliary heat-sensitive wire member 410 are connected to each other to conduct electricity.

The third heat-sensitive wire junction member 330 extends to correspond to the other end of the auxiliary heat-sensitive wire member 410 and the second extended core wire 32 of the heat-sensitive wire 40 as shown in FIGS. 2 and 5 . One end of the second extended heat-sensitive wire 52 disposed in the cable 30 is connected to conduct electricity with each other.
