Description of the Invention: [Technical Field of the Invention] The present invention relates to a functional unit and a switchboard device of a switchboard device, which can be utilized as, for example, a control center for controlling the operation of a motor. [Prior Art] For example, as a functional unit for switching control, protection, and the like of a motor circuit, a plurality of functional units are housed in a distribution panel in a stack of upper and lower sections, and a bus bridge is disposed behind each other in a vertical manner. The contactor of the function sheet 70 is used for powering the collective power distribution panel busbar device, wherein the busbar is a flat-angle conductor, and the front end of the contact plate is bent along the length direction of the flat-angle conductor on the left and right sides thereof. A U-shaped member is formed to form a clamp portion, and a rod-shaped contact member that is pulled out from the machine unit of each segment to the back is inserted between the clamp portions of the contact plate, and is connected to the bus bar for power supply (for example, refer to the patent document) ). The bus bar of the above-mentioned switchboard device is a charging portion. For the sake of safety, a protective cover is provided between the bus bar and the machine unit for protection. In this case, in order to pass the contact sub-portion in the direction of the bus bar, the protective cover is provided with a contact insertion opening that opens in the up-and-down direction at a predetermined interval. As described above, the conventional switchboard device and the functional unit (machine unit) are capable of freely responding to the connection between the busbars and reducing the cost, but are disposed between the busbar and the functional unit at a predetermined interval in the up and down direction. In the case of the protective cover of the opening contact insertion opening, when a functional unit of a special size which is not a predetermined interval is inserted, a wasteful space is generated between the functional units adjacent to each other and there is a problem that the spatial coefficient is poor. 320282 5 200945713

The direction shift causes the displacement of the connection conductor % to retreat, and is ensured in the front-rear direction by the contact holding member 31 (the left-right direction of Fig. 4). Furthermore, in addition to the above-described circuit breaker 22, the functional unit 2 is provided with an electromagnetic switch 23, a secondary contact 24, etc., a primary contact 3 to distinguish between the circuit breakers 2, and a circuit breaker 22 to The electromagnetic circuit breaker 23 and the electromagnetic switch 23 to the secondary side ❹rUf4 are formed by a main circuit connected to the main circuit wiring. Further, various internal devices 25 (25a, 25b, and 25c) are provided for switching control of the motor circuit, and the wiring is connected to the control circuit I1. The @分 breaker 22 is provided with an operation handle for distinguishing the circuit breaker: 2a, etc. However, the configuration, control object, control, and the like of these devices or circuits are not directly related to the characteristic portions of the present invention, and are, for example, widely used, and the conventional portions may be employed, and thus the detailed description thereof will be omitted. /, ❹ frame = = d = f 1, as a function of the special size of a single Si :: standard size small figure shown in Fig. 5: when the second = square is set to 2A, 2B, 2C) The upper jaw is connected to the 3 2C system as shown in the dotted line of Fig. 3 and the fourth figure (4), and the position of the contact member 3 in the upper and lower directions is fixed at the uppermost position, and is inserted into the mounting portion of the frame 1 The contact 3 protruding from the back side will respectively be the contact insertion port corresponding to the shield 14 - and will be fastened to the functional unit 2B at the center portion, so that the position of the contact member 3 in the upper and lower directions is lowered to correspond to the contact. After the position shown by the solid line or the position shown in FIG. 4(b) is inserted in the third port 320282 200945713 of the port l5c, and fixed to the mounting base 21 by a fixing means such as a fixing bolt or the like is omitted, The contact portion 3, which is inserted into the mounting portion, passes through the contact insertion opening 15c corresponding to the protective cover 14, and is engaged with the conductor 12. Further, when the position of the contact 3 is moved in the up and down direction, the connection conductor 32 of the wiring between the contact 3 and the circuit breaker is located between the contact holding member 31 and the women's base 21, and thus does not It affects the internal machinery. ❹ As described above, according to the first embodiment, the contact 3 attached to the functional unit 2 can be moved in the vertical direction. Therefore, even if the contact insertion opening 15 & 15d of the opening of the protective cover 14 is used, When the functional unit of the special size is separated by L, the contact element 3 can be changed from above to below, so that the functional units adjacent to each other in the upper and lower directions do not generate waste space, and the single type of frame corresponds to a plurality of functional units. , can also increase the number of valleys. Therefore, the type of the frame can be reduced and the constituent members can be made productive. Further, when the steep stack is changed, only the mounting position of the contact 3 of the one side can be changed, so that it is not necessary to modify the internal structure of the function tl2. Furthermore, there is no position in the lower direction of the contact 3, and in the conventional functional unit, since the contact is fixed on the upper unit of the functional unit, in the example of Fig. 5, for example, the second from the above When the contacts of the table are inserted into the contact insertion port 15c, an unnecessary dead space corresponding to the size of the drop 3 in the first embodiment is generated between the upper and lower sides (1). However, in the case of the same frame, there is a problem that the number of mountable units is reduced, but in the present embodiment 10 320282 200945713, the state 1 does not have this problem. 'Implemented Bear 2 * Fig. 6 is a conceptual view of the functional unit of the switchboard device according to the second embodiment of the present invention, where (a) is a side view of the upper and lower positions of the contact sub-position at the second level of the standard, (b) It is a side view when the position of the contact sub-position is in the second position. In the figure, the attachment base 21 is attached to the rear side of the functional unit 2 so as to extend in the vertical direction, and the machine type such as the internal device 25 is floatingly fixed to the attachment base 21 via the machine mounting jig 27, and 'once The side contact 3 is configured to be directly attachable to an arbitrary position in the up-down direction of the mounting base 21. Further, since the contact conductors 3 between the primary side contacts 3 and the discrimination circuit breakers 22 are located between the machine mounting jigs 27 and the base 21, as in the embodiment! It does not affect the internal machine's composition. Other configurations are the same as those of the embodiment, and the description thereof is omitted. In the second embodiment configured as described above, as in the embodiment, when the function unit of a special size is used, the position of the contact member 3 in the up-down direction can be changed in accordance with the contact insertion port 15, whereby the function of the up-and-down abutment can be performed. The unit does not create a wasteful space between the units, and the frame can be correspondingly arranged, so that the constituent members can be integrated to obtain an effect of improving productivity, and further, since the contact member 3 is directly mounted on the mounting base 21, the contact is suppressed. The effect of child 3 shaking. In the above-described second embodiment, the device 2 is configured to use the device mounting jig 27 (FIG. 6) for the attachment base 21, but the present embodiment and the 3 system can correspond to, for example, when the internal device 25 is small or not used. When the mounting base 21 is fixed, 320282 11 200945713 The machine mounting jig 27 of the second embodiment is not used, and the constituent unit of the functional unit is directly fixed to the mounting base 21 or the top plate 20, and the second embodiment is configured as The position in the vertical direction of the contact 3 can be directly attached to the attachment base 21 (not shown). As described above, even if the function unit of the jig 27 for the machine mounting is omitted, it is not necessary to change the interval L between the contact sub-inserts 15 on the side of the switchboard, so that the space can be stored without wasting space, and the functional unit can be standardized. Further, in the above-described first to third embodiments, the space in which the displacement of the contact contact 3 and the contact conductor 32 of the circuit breaker U can be retracted as the position of the contact 3 in the vertical direction is changed is ensured. The case of the front-rear direction (the left-right direction of FIG. 4) is of course not limited to this case. For example, the space in which the displacement is retracted in the left-right direction when viewed from the front is also two. At this time, by bringing the space closer to the inner side of the function unit, the space in the rear direction can be reduced. Therefore, the machine to be stored can also correspond to a large size in the front-rear direction. Further, although the height shape of the functional unit of a special size is described as being smaller than the standard size, the same effect can be expected when it is formed to be larger than the standard size. Further, the fixing means of the contact 3 is of course not limited to bolt fixing. At the office.
