Embodiment
For exemplary purposes, these accompanying drawings show and apply the present invention to for example differential switch of the type described in French Patent (FRP) FR 2870987 of electrical switching unit.
This electric unit is well-known equally, and because it is not a theme of the present invention, so be not described in detail here.To only describe understanding element essential to the invention.
Electric unit A comprises in shell B in known manner be mounted to the movable contact support 4,5 that rotates in shell B; Movable contact 2 in the face of at least one fixed contact 3 installation.This movable contact support is mounted between the open position of contact and make position rotates, wherein at open position, movable contact 2 separates with fixed contact 3, and in make position, movable contact 2 is by being pressed on the fixed contact 3.
This movable contact support comprises and being mounted to respect to first support 4 of the shell B of described unit rotation and the several supports 5 that are called second support, is mounted to support 5 with respect to 4 rotations of first support and is designed to support movable contact 2.
In this certain embodiments, by being mounted to axle formation first support 4 with respect to the shell rotation of unit.This comprises the housing 6 that is designed to receive the contact supporting 5 that is called second support, and movable contact 2 is installed in the contact supporting 5.In these housings 6 each is that two sidewalls 7,8 by contact back shaft 4 limit, and each sidewall 7,8 comprises that 9,10, two knuckle-pins of knuckle-pin 9,10 form the jointed shaft of contact supportings 5.
According to describe and illustrated embodiment, contact pressure spring 15 is installed in the contact supporting that is called first contact supporting, promptly axle 4 and is called between each contact supporting 5 of second contact supporting.
The hinge axes Y of the hinge axes of first support 4 and second support 5 separates, thereby movable contact slides on fixed contact when contacting between movable contact and the fixed contact.
Each contact supporting 5 that is called second contact supporting is included in two flanges 11,12 of its bottom and top mechanical connection, and between two flanges formation housing 13, housing 13 is designed to hold the movable contact 2 of the form of contact blade 14.This support 5 that is called second support also comprises the device (not shown) that is used for holding piece 14 is clamped in the inside of the support 5 that is called second support.Above-mentioned two flanges 11,12 of each second support 5 comprise two holes 16,17 on its outer surface, hole 16,17 are designed to hold respectively when contact supporting 5 being installed in the contact supporting 4 that is called first contact supporting above-mentioned two knuckle-pins 9,10 of the respective housings 6 of axle 4.
Second contact supporting 5 also comprises next door 18, next door 18 is designed to the part of occulting disk to the movable contact 2 of the contact zones of fixed contact 3, only this next door 18 is installed on the side of second support 5, thereby permission is inserted contact by the bending of described support and is clamped in second support 5.
Can notice that in Fig. 3,4 and 5, according to another embodiment, form opening in one in two flanges of contact supporting, this opening can increase the pliability of assembly, to prevent from when assembling, to be called contact supporting 5 fractures of second contact supporting.
Because second support 5 is hinged on first support 4, so compared with prior art, each movable contact 2 is positioned to such an extent that dispersion is less.Owing to the shape of contact and axle, so hinged dispersion, the inaccuracy of dividing breaking up to cause contact to be located eliminated.Now, positioning contact in an identical manner always.The wearing and tearing of contact back shaft are reduced to minimum.
All phase contact of contact back shaft (phase contact) all contact with fixed contact simultaneously.All phase contact of contact back shaft are all left fixed contact simultaneously.Performance closed and that open is improved and is reproducible.
Because the axis of contact supporting is with respect to the fact of the axis runout of contact back shaft, so when contacting between movable contact and the fixed contact, movable contact slides on fixed contact, this slip has produced the effect of self-cleaning.
Because contact supporting has sealed contact with insulation and increase the fact of leakage distance, so strengthened these contacts and with respect to the insulation between the front panel.Therefore, needn't be in the distance between the axis that increases next door or increase contact on the contact back shaft.
Because the contact pressure spring by the fact that is pressed on the contact supporting, so the contact pressure spring is not subjected to tension force, therefore, needn't provide extra insulation next door.
Owing to there is the next door on the side be fixed on the movable contact support, thus by the movable contact towards described fixed contact contact zones partly move more approaching described fixed contact, and do not reduce gap between the contact.Therefore, the shape of contact is complicated to obtain appropriate gap.
Also can change the contact back shaft contact plate of different-thickness just can be installed.Have only second contact supporting to have to change.
Therefore, a kind of electrical switching unit and a kind of contact axle that can reproduce the performance of this unit have better been realized by the present invention.
The present invention advantageously is applied in one pole or the multipole switch, and in the differential switch.
The present invention be not defined to describe and illustrated embodiment, wherein said embodiment just provides for exemplary purposes.
Therefore, in the embodiment that describes, each movable contact is hingedly mounted in the different supports.
In another embodiment, it is contemplated that all movable contacts are mounted in the single support.
On the contrary, the present invention expands to all technical equivalents thing and combinations thereof that comprise described mode, if latter's spirit according to the present invention is achieved.
