Problems solved by technology

Therefore, if the input / output terminal is installed with an inclination with respect to the terminal seat sheet with a gap due to poor construction, etc., causing poor contact, the contact resistance of the input / output terminal with respect to the terminal seat sheet becomes large, and the contact resistance from the above-mentioned input / output terminal The larger contact resistance part will generate heat, which will have a bad influence on the surrounding components

Embodiment 1

[0039] Next, use figure 1 and figure 2 Example 1 of the present invention will be described. The terminal block device 1 in Embodiment 1 of the present invention is installed in the case 11 that accommodates various electronic components such as a booster circuit, an inverter circuit, or a filter circuit constituting a power conditioner, and an arithmetic device that controls these circuits. outer side. Furthermore, the terminal block device 1 is constituted as an insulator by mold-molding a synthetic resin, and has terminal mounting blocks 2, 2 in two upper and lower layers.

[0040] Each terminal mounting base 2, 2 is installed by, for example, sandwiching a washer 5a and tightening a screw 5 in a state where a conductive terminal base piece 3, 3, ... electrically connected to an electronic component on the power conditioner side is interposed therebetween. There are, for example, input / output terminals 4, 4, . . . which are crimp terminals. Each input / output terminal 4...

Embodiment 2

[0047] Figure 5 Example 2 of the present invention is shown. Figure 5 In the illustrated embodiment 2, a pair of adjacent input and output terminals 4, 4 is electrically connected to each other in pairs, and a hair pad as a foam material installation part is formed on the terminal mounting bases 2, 2. Foam material storage room 9a, and in the foam material storage room 9a, store and set the heat-reactive foam material 8, and form in the terminal mounting table 2 for making due to the bad contact of input-output terminal 4 and terminal pedestal piece 3 When the temperature rises, the volume-expanded foam material 8 leads to the insertion hole 2a on the input-output terminal 4 side, and the input-output terminal 4 is lifted by the volume-expanded foam material 8 from the insertion hole 2a due to the temperature rise. Lift up and press against the side of the terminal pedestal sheet 3 to eliminate the poor contact between the two. Other configurations are the same as those of...

Embodiment 3

[0050] Figure 5 Example 3 of the present invention is shown. according to Figure 5 A foam material storage chamber 9a as a foam material setting part is formed on the terminal mounting table 2, and a heat-reactive foam material 8 is accommodated in the foam material storage chamber 9a, and a foam material 8 is formed on the terminal seat sheet 3 from the foam material. The cutout portion 3a of the material 8 extending toward the input-output terminal 4 side bends the terminal seat sheet 3 due to the volume expansion of the foam material 8 and presses it against the input-output terminal 4, so that the terminal seat sheet 3 is crimped on the input-output terminal 4. on terminal 4, thereby eliminating poor contact. Other configurations are the same as those of the first embodiment described above.

[0051] According to the structure of the above-mentioned embodiment 3, for example, when the input / output terminal 4 becomes inclined relative to the terminal seat sheet 3 and i...

Abstract

Electronic components which form a power conditioner, etc. are housed in a case (11), input / output terminals (4) to which an electric power source is connected are mounted on the outer surface of the case (11) with a terminal base piece (3) provided between the outer surface of the case (11) and the input / output terminals (4), and a heat responsive foaming material (8) is disposed on the foaming material mounting section (9) of a terminal mounting base (2) so as to face the input / output terminals (4). When temperature reaches a predetermined level due to the failure of contact of the input / output terminals (4) with the terminal mounting base (2), the foaming material (8) is expanded in volume to make the input / output terminals (4) in pressure-contact with the terminal base piece (3), and as a result, the failure of contact is eliminated.

Description

technical field [0001] The present invention relates to a terminal block device configured by arranging a plurality of terminals for connecting to a power source on a terminal mounting portion on an outer surface of a case housing electronic components such as a power conditioner. Background technique [0002] In recent years, a power supply system has been developed that interconnects distributed power sources such as solar power generation and fuel cells with commercial power sources, and supplies power to devices (loads) in the home through the distributed power source, or in the distributed power source If power is not supplied in the middle, power is supplied from the system side. In such a power supply system, since the electric power supplied from the distributed power source is direct current, the direct current is converted into alternating current through a power conditioner, and electric power is supplied to devices in the home. [0003] A power conditioner of su...
