Modes for Carrying Out the Invention

[0010] Hereinafter, an example of the present disclosure will be described with reference to the accompanying drawings. The following description is merely exemplary in nature and does not limit the present disclosure, its applications, and its uses. The accompanying drawings are schematic drawings, and the illustrated configurations and actual products may have different ratios of each dimension, etc.

[0011] As shown in FIG. 1, the terminal block set 1 according to one aspect of the present disclosure includes a first terminal block 10 and a second terminal block 20. In this aspect, the first terminal block 10 and the second terminal block 20 are push-in connection type terminal blocks. As shown in FIG. 2, the second terminal block 20 constitutes a part of the power supply device 2.

[0012] As shown in FIGS. 3 and 4, the first terminal block 10 and the second terminal block 20 are electrically connected via a conductive member 30. The conductive member 30 includes, for example, a copper plate and an electric wire. In this aspect, power is supplied from the first terminal block 10 to the second terminal block 20 via a cable 50 (an example of a conductive member) connected to the first terminal block 10.

[0013] The first terminal block 10 is configured to be electrically connectable to other terminal blocks including the second terminal block 20. The first terminal block 10 includes a determination unit 11 and a display unit 12. In this aspect, the first terminal block 10 and the second terminal block 20 include connection portions 13 and 21, and are electrically connected via the connection portions 13 and 21. A cable 50 is connected to the connection portion 13 of the first terminal block 10.

[0014] The determination unit 11 is configured to determine whether the first voltage output to the connected second terminal block 20 or the second voltage input from the connected second terminal block 20 is normal. In this embodiment, the determination unit 11 is configured by a circuit shown in FIG. 7 as an example. In the circuit of FIG. 7, an AC voltage is input from an external power supply 60 to the first terminal block 10. The input AC voltage is divided and input to the comparator IC110. If the input AC voltage is equal to or higher than the threshold value, it is determined that the first voltage is normal, and current flows through the terminal K to the display unit 12, and the LED 121 lights up. Regarding the second voltage, it can also be determined whether it is normal with the same circuit configuration as the circuit shown in FIG. 7. In this case, the DC voltage output from the power supply device 2 is input to the first terminal block 10. The input DC voltage is divided and input to the comparator IC110. If the input AC voltage is equal to or higher than the threshold value, it is determined that the second voltage is normal, and current flows through the terminal K to the display unit 12, and the LED 121 lights up.

[0015] When the determination unit 11 determines that the first voltage or the second voltage is normal, the display unit 12 is caused to display that "the first voltage is normal" or "the second voltage is normal".

[0016] The determination unit 11 may include a processor 111 and a storage device 112. The processor 111 and the storage device 112 may constitute, for example, a part of the circuit shown in FIG. 7. The processor 111 includes, for example, a CPU, an MPU, a GPU, a DSP, an FPGA, an ASIC, or a combination thereof. The storage device 112 includes, for example, a non-transitory computer-readable storage medium configured by an internal recording medium or an external recording medium. The internal recording medium includes a non-volatile memory and the like. The external recording medium includes a hard disk drive (HDD), a solid state drive (SSD), an optical disk device, or the like. The determination unit 11 may be configured to transmit and receive data to and from an external device such as a server via a communication circuit or a communication module.

[0017] When it is determined that the first voltage or the second voltage is normal, the display unit 12 is configured to be able to display that "the first voltage is normal" or "the second voltage is normal".

[0018] In this embodiment, the display unit 12 includes a light-emitting element 121. The light-emitting element 121 includes, for example, an LED (light-emitting diode) 122 and a light guide member 123 as shown in FIG. 4. The LED 122 is located on a substrate 124 facing the second terminal block 20 of the first terminal block 10 in a state where the first terminal block 10 and the second terminal block 20 are connected. When the LED 122 lights up, it indicates that "the first voltage or the second voltage is normal".

[0019] The first terminal block 10 and the second terminal block 20 include housings 101 and 201, and each connection part 13, 21 is located inside the housings 101 and 201. Each connection part 13, 21 includes terminal parts 131, 211 configured to contact the housed conductive member 30.

[0020] In a state where the first terminal block 10 and the second terminal block 20 shown in FIG. 4 are connected by the conductive member 30, the housing 101 of the first terminal block 10 has openings 102, 103 located on the surface opposite to the surface facing the second terminal block 20. The openings 102, 103 are adjacent to each other. The housing 201 of the second terminal block 20 has openings 202, 203 located on the surface facing the first terminal block 10. The openings 202, 203 are adjacent to each other. The openings 102, 103 of the first terminal block 10 are connected to the connection part 13, and the openings 202, 203 of the second terminal block 20 are connected to the connection part 21. In this embodiment, the housing 101 has a plurality of openings 102, 103, and the housing 201 has a plurality of openings 202, 203. The same number of openings 102, 103 are provided in the housing 101. The same number of openings 202, 203 are provided in the housing 201.

[0021] As shown in FIGS. 4 and 5, the connection portion 13 of the first terminal block 10 has, as an example, a leaf spring 112. The leaf spring 212 can sandwich and hold the cable 50 accommodated through the opening 102 together with the terminal portion 131, and is configured such that the holding of the cable 50 can be released by a jig (not shown) accommodated in the connection portion 13 through the opening 103.

[0022] As shown in FIGS. 4 and 6, the connection portion 21 of the second terminal block 20 can accommodate a part of the conduction member 30, and is configured such that a part of the accommodated conduction member 30 can be held and the holding of the accommodated conduction member 30 can be released by a jig 40. A part of the conduction member 30 is accommodated in the connection portion 21 through the opening 202 of the housing 201. The opening 202 is an example of the first opening.

[0023] As an example, the connection portion 21 has a leaf spring 212. The leaf spring 212 can sandwich and hold the conduction member 30 accommodated through the opening 202 together with the terminal portion 211, and is configured such that the holding of the conduction member 30 can be released by a jig 40 accommodated in the connection portion 21 through the opening 203. A part of the jig 40 is fixed to the housing 101 of the first terminal block 10 and extends outside the housing 101 from the opening 103. A part of the portion of the jig 40 located outside the housing 101 is accommodated inside the connection portion 21 through the opening 203 of the housing 201. By bringing the first terminal block 10 and the second terminal block 20 closer to each other, the jig 40 contacts the leaf spring 212 and the holding of the conduction member 30 is released. The opening 203 is an example of the second opening.

[0024] Referring to FIG. 8, an example of a display process for displaying the second normal state using the terminal block set 1 will be described. This display process is implemented, for example, by the processor 111 executing a predetermined program stored in the storage device 112.

[0025] As shown in FIG. 8, when the display process is started, it is determined whether the second terminal block 20 is connected (step S1). Step S1 is repeated until it is determined that the second terminal block 20 is connected. The determination unit 11 determines that the second terminal block 20 is connected, for example, in the cases shown below. · When a predetermined signal output from the second terminal block 20 is received. · When a start operation of the display process is performed on the first terminal unit 10 by the user.

[0026] When it is determined that the second terminal block 20 is connected, the determination unit 11 acquires the first voltage or the second voltage (step S2). When the voltage is acquired, the determination unit 11 determines whether the acquired voltage is normal (step S3). Whether the acquired voltage is normal is determined, for example, by whether the acquired voltage is equal to or higher than a predetermined threshold value. The predetermined threshold value of the voltage is set, for example, according to the specifications of the second terminal block 20 or the like.

[0027] When it is determined that the acquired voltage is normal, the determination unit 11 causes the display unit 12 to display that "the acquired voltage is normal" (step S4).

[0028] When it is not determined in step S3 that the acquired voltage is normal, or when it is displayed on the display unit 12 in step S4 that "the acquired voltage is normal", the determination unit 11 determines whether to end the display process (step S5). The determination unit 11 determines to end the display process, for example, in the cases shown below. · When a predetermined signal output from the second terminal block 20 is not received for a predetermined period or longer. · When an end operation of the display process is performed on the first terminal unit 10 by the user.

[0029] When it is determined that the display process is to be terminated, the display process ends. When it is not determined that the display process is to be terminated, the process returns to step S2, and the first voltage or the second voltage is acquired. If it is displayed on the display unit 12 in step S4 that "the acquired voltage is normal", the process returns to step S2 while "the acquired voltage is normal" is being displayed on the display unit 12. If it is not determined in step S3 that the voltage acquired in the state where "the acquired voltage is normal" is being displayed on the display unit 12 is normal, the determination unit 11 ends the display of "the acquired voltage is normal" on the display unit 12.
