Embodiment
Execution mode 1
Below, based on accompanying drawing, describe embodiments of the present invention 1 in detail.Fig. 1 means the oblique view of the state before the combination of derailing switch main body 1 in embodiments of the present invention 1 and inserted terminals device 2.Fig. 2 is by the clamping terminal that is arranged on derailing switch main body 1 side in Fig. 13 and is arranged on the blade terminals 4 of inserted terminals device 2 sides and pressing plate 5 is selected out and carried out illustrated figure.Fig. 3 is after derailing switch main body 1 and 2 combinations of inserted terminals device, observes the profile of clamping terminal 3 and blade terminals 4 peripheries from the arrow apparent direction A of Fig. 1, and Fig. 4 is the profile from the arrow apparent direction B observation of Fig. 1.Fig. 5 is the details drawing of blade terminals 4, and Fig. 5 (a) is oblique view, and Fig. 5 (b) is the profile of observing from the direction identical with Fig. 4.In addition,, in each figure, for identical structure, mark identical label.
In Fig. 1, circuit is carried out to the derailing switch main body 1 of switch, be circuit-breakers such as Inturruptor for sub-line or residual current circuit breaker.Derailing switch main body 1 utilizes the insulation framework 9 consisting of the lid 9a of framework shape and the pedestal 9b of frame shape to form appearance.
In addition, known by handle 10 that part from lid 9a is protruded, to the diagram of Fig. 1, right-hand or diagram left carries out rotating operation, makes conducting or non-conduction between the power supply side terminal 11a of derailing switch main body 1 and load side terminal 11b.In addition, the right side of Fig. 1 is mains side, and left side is load-side.In Fig. 1, the position of illustrated handle 10 is positioned at load-side, and derailing switch main body 1 is in nonconducting state.
In addition, on power supply side terminal 11a and load side terminal 11b, be connected with separately clamping terminal 3, from clamping terminal 3 to power supply side terminal 11a or load side terminal 11b can conducting.
On the other hand, inserted terminals device 2 is fixed on the structures such as distribution board in advance.Inserted terminals device 2 forms appearance by insulating resin, has: base portion 2a, and it is fixed on the panel or angle bar of not shown distribution board etc.; And the portion of terminal 2b that amounts to 6 positions, it is positioned on each 3 positions of base portion both sides.
On each portion of terminal 2b, be fixed with blade terminals 4, they are positioned on relative with the clamping terminal 3 of derailing switch main body 1 respectively position.Derailing switch main body 1 and inserted terminals device 2 can by make clamping terminal 3 with the blade terminals 4 relative with them respectively in conjunction with assembling.
Below, the detailed structure of clamping terminal 3 and blade terminals 4 is described based on Fig. 2.Clamping terminal 3 is formed by conductive metal, and integral body forms roughly U word shape.Clamping terminal 3 at one end has and the power supply side terminal 11a of derailing switch main body 1 and the connecting portion 3b of load side terminal 11b electrical connection, has the compressing piece 3a that can clamp plate object in its contrary one end.Between compressing piece 3a, can clamp plate object by crimp force.
In blade terminals 4, the bending of tabular conductive metal is formed to the box shape portion of box shape, and have and will vertically erect the tabs 4a forming with box shape portion continuous board-like material.For position relationship, box shape portion is configured in the opposition side of clamping terminal 3 across tabs 4a.In addition,, at the pressing plate 5 for stoping blade terminals 4 to be jumped out, be provided with the through hole for tabs 4a is protruded.
Fig. 3 means the details drawing of the connection status of clamping terminal 3 and blade terminals 4, be from vow apparent direction A observe the derailing switch main body 1 of Fig. 1 and inserted terminals device 2 in conjunction with time the profile of state.Fig. 4 is when the state identical with Fig. 3, the profile of observing from the arrow apparent direction B of Fig. 1.
Clamping terminal 3 directly or via pad 6, by not shown bolt etc., to be fixed on the power supply side terminal 11a that derailing switch main body 1 possesses upper, is electrically connected.In addition, blade terminals 4 remains on the portion of terminal 2b of inserted terminals device 2, by pressing plate 5, is fixed.Now, the tabs 4a of blade terminals 4 runs through pressing plate 5.In addition, in blade terminals 4, as and external conductor 7 between connecting portion and there is internal thread part 4b, can utilize it by bolt 8 and external conductor 7, to be spirally connected.
When derailing switch main body 1 is connected with inserted terminals device 2, the tabs 4a of the compressing piece 3a of relative clamping part 3 clamping blade terminals 4, is electrically connected clamping part 3 and tabs 4a by contact.Thus, form the circuit from external conductor 7 to power supply side terminal 11a.In addition, because not shown load-side is also identical structure, so with Fig. 3 and Fig. 4 in the same manner, form never illustrated load-side external conductor to the circuit of load side terminal 11b.
Fig. 5 illustrates the detailed structure of blade terminals 4, and Fig. 5 (a) is oblique view, and Fig. 5 (b) is the profile of observing from the direction identical with Fig. 4.Blade terminals 4 has the tabs 4a by the compressing piece 3a clamping of relative clamping terminal 3, in this blade terminals, form box shape to support this tabs 4a, a side contrary with tabs 4a side in this box shape, have for connecting the internal thread part 4b of external conductor 7, they are that continuous OBL conductor plate bending is formed.One end of OBL plate forms tabs 4a, and tabs 4a is supported from downside on one side in its contrary one end, on one side especially at its end formation fitting portion 4c, chimeric with the embedded hole 4d being arranged on the part of box shape.
By continuous OBL conductor plate, at kink 4e, 4f, 4g and 4h place, inside Zhou Fangxiang bends and formation box shape this blade terminals 4.In addition, at kink 4i place, to peripheral direction bending, with respect to the above-mentioned part that forms box shape, one end of OBL conductor plate is vertically erect, form thus tabs 4a.
In addition,, for kink 4e, 4f, 4g, 4h and 4i, also can pass through to use the material low with other part phase specific rigidities of blade terminals 4, and they are easily bent.
Above, in the related inserted terminals device of present embodiment, can provide following blade terminals 4, it is with respect to be applied to the load on tabs 4a, comparatively robust when derailing switch main body 1 is connected with inserted terminals device 2.
In addition, can provide assembling easy and cheap blade terminals 4.
In addition, owing on the OBL conductor plate in bending, hole being set, when this conductor plate bending is formed to box shape, fitting portion 4c is inserted in above-mentioned hole, so can make blade terminals 4 firmer.
Execution mode 2
Fig. 6 illustrates the detailed structure of the blade terminals 14 in embodiments of the present invention 2, and Fig. 6 (a) is oblique view, and Fig. 6 (b) is the profile of observing from the direction identical with Fig. 4.In Fig. 6, for the structure identical with Fig. 5, also description thereof is omitted to mark identical label.
The basic structure of the blade terminals 14 in execution mode 2, identical with the blade terminals 4 in execution mode 1, but following 2 different from execution mode 1,, make internal thread part 4b become simple through hole 13, and there is nut 12 in the inner side that forms the blade terminals 14 of case shape.
As nut 12, can use the female parts of tool such as hex nut or special nut, can possess the function identical with execution mode 1, the internal thread part 4b of execution mode 1 is replaced into simple through hole 13 simultaneously, thereby does not need screw thread processing.
According to said structure, in execution mode 2, can obtain comparing with execution mode 1 blade terminals 14 of the more simple and easy making of structure.
