Fig. 2 is the top view of described device;

Fig. 3 is the perspective view of described device and power supply comb thereof;

Fig. 4,5 and 6 is respectively expression device of the present invention end view after this comb is connected, top view and perspective view.

Embodiment

In the accompanying drawings, the module circuit breaker D of one three utmost point and middle line style can be designed to install by being clipped on the track (not shown), and is arranged side by side so that protective circuit can short circuit with other devices of same type.This circuit breaker D is accommodated among the shell B who roughly is parallelepiped shape, and it has a back side a who comprises the device that is used to be clipped on the track; Two with the perpendicular parallel interarea b of back side a, c, this device can be adjacent with other protective devices in orbit thus; A front d who is roughly parallel to back side a; With two side e, f, one of them side e that is called as joint face comprises

splicing ear

1,2,3,4, is used for handle assembly D and is connected to other devices arranged side by side.This circuit breaker D is designed to be powered by the device (not shown) that line side in orbit is set, and powers for other device (not shown)s that are arranged on load-side by this device.As seeing, by by four

power supply bars

9,10 at Fig. 3 to 6,11,12 comb P that form realize interconnecting of different device, and each power supply bar is formed by a vertical part s, evenly spaced thus tooth d stretches out perpendicular to described vertical part s, each power supply bar transmission center line or a phase.Bar 9 to 12 is arranged on the comb P by this way: described comb P along track with the mode that repeats distribute continuously center line n and different phase p1, p2, p3 wherein has a tooth that center line n is distributed in two continuous phase tooth p1, p2 is between the p3.

As at Fig. 2,3,5 and 6 are seen, circuit breaker D comprises four module m1 that hold a neutral circuit and three-phase circuit respectively, m2, m3, m4.Each module m1 to m4 comprises 1,2,3,4 and

grooves

5,6,7,8 of a terminal on the joint face e of shell.In any module, from the central authorities of groove 5 to 8 to

terminal

1,2, when the plane R that presses the back side a of the plane of track or device apart from r of 3,4 central authorities considers, roughly corresponding to half of the width L of a module, and, corresponding to the distance between two continuous tooth d of comb P, also consider that by this same level R this is apart from the spacing of representing device or comb simultaneously.According to this embodiment, the value of spacing is 9mm, and the width L of module is 18mm.

Like this, the first module m1 from left to right comprises a groove 5 that is used for the locator of the untapped p3 of tooth mutually of terminal 1 and formation that is designed to accept a center line tooth n.The second module m2 comprises that a groove 6 that is designed to hold a untapped center line tooth n is designed to accept the terminal 2 of tooth p1 mutually with one.Three module m3 comprise a groove 7 that is used to hold a center line tooth n with one be used to accept one mutually terminal 3, the four module m4 of tooth p2 comprise that a groove 8 that is used to hold a center line tooth n is used to accept the terminal 4 of tooth p3 mutually with one.

According to the present invention, for each module m1 to m4, stagger on degree of depth q direction in shell mutually in terminal and groove (1,5), (2,6), (3,7) and (4,8), and this degree of depth is confirmed as perpendicular to the plane R of track and back side a and is parallel to joint face e.Like this, according to this embodiment of expression in the accompanying drawings, with respect to the groove 5 of terminal 2 to the 4 with tooth mutually that is designed to accept to comb, terminal 1 and the groove 6 that is designed to the center line tooth n that accepts to comb stagger on the degree of depth mutually to 8.The terminal of the same degree of depth and groove be by a segment distance separately in twos, and this distance is roughly corresponding to the width of a module.Terminal on same module and groove staggering on the degree of depth can make the following setting of terminal: width is the mid-plane M that the terminal openings O of l extends beyond module, the width of described terminal openings is parallel to orbit plane R, described mid-plane M is parallel to the interarea b of described module, c.Like this, because this feature can be used the terminal with higher power capacity, that is, for example, terminal is suitable for accepting to have 25mm ²The cable of cross section.The opening of the expansion of these terminals just can make have bigger width and can transmit above 40A for example the tooth of the higher electric current of 63A be inserted in these terminals.In Fig. 3 to 6, the comb of a transmission heavy current can be seen on link position, and all teeth are inserted in the terminal.

At Fig. 2, in 3,5 and 6, can see that in the opening O of terminal and that side between the track, terminal 1 to 4 has a U-shaped opening O and a semicircular collar 13 is housed, be placed on around the cup dolly 14 of opening O of terminal 1 to 4.This collar 13 by a kind of insulating material for example plastics form, and particularly when device is provided heavy current, can between live part and operating personnel's finger, obtain certain insulation distance significantly.Another function of this collar 13 is the guiding of carrying out the cable in the opening of the guiding of tooth d or terminal.This collar 13 also has the easier effect of being discerned by naked eyes of terminal that makes.

In fact, the present invention is not limited in the purpose that is used for example and the embodiment that describes and illustrate.

For example, the present invention can be used to the device of the other types except circuit breaker, and, in conventional method, be used to any modular electrical apparatuses, each module comprises a phase or a neutral circuit, and, on its joint face, a terminal and a locator or a groove are designed to accept a comb teeth or analog, even this device in fact also can be by cable power supply.

Should be known in by same procedure on joint face, not have recessed locator and the terminal that stretches out.

On the contrary, present invention includes the equivalent and the combination thereof of the said apparatus that spirit obtains according to the present invention.
