Description of the invention (2) The quality of the bleed 50 was too large and was damaged. The load is applied to the mounting base H) c, so that the mounting base is usually 'used for a large-capacity frame such as 4_ to ampere [the connection terminal of the motor bank has a structure shown in, for example, Figure 9 to Figure μ' 4 It suppresses the temperature rise caused by the thermal convection of the load-side terminal (not shown) and the busbar 50, and it has a vertical conversion structure between the vertical part and the outer flat surface. The horizontal terminal is welded and welded. μ is joined to the vertical terminal 33. As shown in FIG. 11 and FIG. 12, a first positioning groove ^ having a U-shaped notch 33 b for fitting the vertical terminal 33 is formed in the horizontal terminal 31 to fix a plurality of mounting holes 31 b to the reinforcing plate 40 with screws. And a notch 31c for fitting into the mounting base 10c. The vertical terminal 33 is formed with a plurality of mounting holes 33a for fastening the bus bar 50 by a bus connection screw (not shown) described later; and a U-shaped notch 33b for engaging the horizontal terminal 31. In the conventional bus connection terminal configured as described above, in order to connect the predetermined bus 50 determined by the rated current, the interval L1 (Fig. 10) between the plurality of vertical terminals 33 is set to be 5 more than the specified bus 〇The thickness of the plate should be large. For example, when the plate thickness L0 of the busbar 50 is specified to be 10 mm, the interval L1 of the vertical terminals 33 is set to 10.5 mm to 115 mm, which can only give a little extra space. In addition, since the interval between the busbars 50 (refer to Figure ^ 4) needs to be at least the same as the plate thickness L 0 of the bus bar 50, the plate thickness of the vertical terminals 33 cannot be made smaller than L0. Therefore, as shown in Figures 13 and 14, connect the terminals on the bus (please read the precautions on the back before filling this page)

In this state, the contact portion between the vertical terminal 33 and the bus bar 50 is not the portion S1 where the vertical terminal 33 and the bus bar 50 are overlapped, but only from the end surface of the vertical terminal 33 to the bent position of the vertical terminal 33 Only the part S2 between them, so that the electrical contact area between these conductors becomes smaller than the area that should be obtained originally. Therefore, the electrical contact resistance between the bus 50 and the vertical terminal 3 3 will increase. Furthermore, it is difficult to discharge the internal heat of the circuit breaker 10b to the busbar 50 through the busbar connection terminal 30, and there is a problem that the temperature of the circuit breaker 10b cannot be sufficiently reduced. Furthermore, as shown in FIG. 11 and FIG. 12, in order to connect the plurality of bus bars 50, a plurality of positioning grooves 31a must be formed in the horizontal terminal 31, and a plurality of vertical terminals having holes 33a and cutouts 33b must be made, respectively. 33, and many of these parts must be welded to each other, so that the production cost of the bus connection terminal 30 is high. Therefore, an object of the present invention is to provide a bus connection terminal 'that solves the above-mentioned problems, and to obtain a stable and good electrical and thermal connection relationship between the bus and the bus connection terminals. In addition, the object of the present invention is to obtain a bus connection terminal which is easy to manufacture, has the same reliability, and is inexpensive.

Description of the invention (7 The support section 72 is composed of a single conductor block member in the chart and financial department, and in Figures 7 to 14 In the conventional connection terminal shown in the figure, a portion corresponding to the support portion is formed by a plurality of plate members. In addition, a groove 7 2 e is provided to receive the conductor portion 7 1. Each of the plurality of connection plates is provided. As shown in FIG. 4, the portion 73 has a plate thickness L1 at least equal to the plate thickness L0 of the bus bar 50 to be connected, so that the interval between the connected bus bars 50 is an appropriate size L1. The interval L2 of the connection plate portion 73 is a slightly larger interval L2 than the thickness L0 of the bus bar, which makes it easy to insert the bus 5G. Furthermore, it is provided for inserting the bus bar 50 into the interval and not shown. The bolt hole tightened by the bolt and the nut is 7%. According to the present invention, in order to provide a sufficient contact area for electrical properties and heat, the plurality of connection plate portions 73 are each provided with a very large size S3 ( (See Figs. 4 and 6) the contact surface portion 73b is supported by the support portion 72 through the flexible portion 74. The flexible portion 74 is a thin-walled portion having a thickness L3 which is thinner than the thickness of the connecting plate portion 73. It can be seen from the comparison of the flexible portion 74 with FIGS. 4 and 6 that the bus bar 50 having a thickness L0 and the connecting plate portion 73 form an interactive inclusion, and the bolt 60 and the nut 65 as the locking member When locked, the flexible portion 74 is easily bent and deformed, and the entire “displayed contact surface 73b” of the connection plate portion is closely attached to the bus bar 50. Therefore, the bus bar 50 and the connection plate portion function. The electrical contact resistance between 73 will not increase, and it will not hinder the movement of heat between them, and it can sufficiently dissipate heat from electrical equipment such as circuit breaker 10b. The flexible portion 74 is shown in the legend It is formed as a groove 73c with a roughly circular cross-section, but it can also be a polygon such as a rectangle or an ellipse.

Description of the Invention (8) The support section 72, the connecting plate section 73 and the flexible section 74 are formed as a continuous integral conductor block 75. The conductor block 75 is a bus bar formed by pushing out and forming a long-length material including a support 邛 72, a connection plate portion 73, and a flexible portion 74 in a cross-sectional shape as shown in FIG. 4 as a bus bar at an appropriate predetermined size. Those who connect the terminals. Therefore, the manufacturing process required in the past is no longer needed, that is, a plurality of horizontal terminals 31 as shown in Figs. 11 and 12 are produced, and a plurality of positioning grooves 31a are formed in the plurality of horizontal terminals, respectively. The process of making a plurality of vertical terminals 33 with holes 33a and cutouts 33b and welding and assembling most of these parts with each other can reduce the manufacturing cost of the bus connection terminals, and the conductor block is not assembled. Therefore, the reliability is high. In the above description, although the bus connection terminal for connecting the bus to the circuit breaker is taken as an example for description, the bus connection terminal of the present invention can of course be generally used for electromagnetic contact of wiring on the bus And other electrical equipment such as switches and shutters. [Industrial Applicability] As described above, the busbar connection terminal of the present invention is particularly useful as a busbar connection terminal that connects a plurality of busbars to a high-current energized electrical device such as a circuit breaker. .
