Definitions
- the present invention relates to a switch four-pole differential with four fixed contacts and four corresponding movable contacts arranged in line and comprising a differential sensor arranged for detect a leakage current and to transmit a signal corresponding to a connected control device to said sensor, this device being coupled to a mechanism release to activate a switching rod bearing the moving contacts of the switch.
- the differential sensor In differential switches of this type (see for example FR-A-2 478 368), the differential sensor generally consists of a toroidal winding surrounding the supply conductors of the electric current and the controller is a relay which powers the trigger mechanism at when the sensor transmits its signal. This happens as soon as the sum of the currents in the conductors is not zero, which means that the circuit leaks to the earth.
- the mechanism of trigger usually involves a lever which releases the bar carrying the movable contacts for allow the opening of said switch contacts.
- the switch bar had the same configuration for the four contacts, it would be impossible to predict the order in which the switch contacts differential would close when a current of leak is detected.
- the current differential switches are designed so that the contact corresponding to neutral closes before contacts corresponding to the phases.
- the switching rod carrying the contacts mobile is constructed in such a way that the gap between mobile and fixed contacts which correspond to neutral is smaller than the differences between the contacts corresponding to the phases. In this way, at the time of tripping, it is guaranteed that the closing sequence contacts is the one we want, namely in order: neutral - phase - phase - phase.
- phase - phase - neutral - phase is also tolerated.
- phase - phase - neutral - phase is also tolerated.
- phase - phase - neutral - phase is prohibited: phase - phase - neutral - phase, and phase - phase - phase - neutral, because that they generate compound tensions.
- the present invention proposes to overcome these disadvantages by making a switch of the type mentioned above which removes both the increase production and storage costs and risks mounting errors for the user.
- the differential switch four-pole characterized in that said bar includes means for reducing the gap between moving contacts and fixed contacts correspondents arranged at both ends of said contact line.
- said means have peripheral bulges on the switching bar.
- the four-pole differential switch 10 includes a housing 11 provided with four input terminals 12a, 12b, 12c and 12d, and four output terminals 13a, 13b, 13c and 13d.
- the input terminals are, for example, respectively connected to fixed contacts 14a, 14b, 14c and 14d
- the output terminals are, in this case, respectively connected to movable contacts 15a, 15b, 15c and 15d.
- the fixed contacts are arranged on conductive elements connected respectively to the terminals entry.
- the movable contacts are mounted in a way known per se on a rotary switching rod 16 around its axis which is coupled to a mechanism of trigger 17 also known.
- This bar has the function of a camshaft, the movable contacts being biased against these cams by means of springs thrust.
- the geometric shape of these cams which present in the form of a peripheral bulge respectively 18, 19, defines the distance between the contacts mobiles and the corresponding fixed contacts.
- These bulges can be made by molding or machining and are in one piece with the switch bar. They can also be made up of elements reported.
- Figure 2 shows the construction more precisely and the arrangement of the mobile contacts 15a, 15b, 15c and 15d. It can be seen that the end contacts 15a and 15d are offset from the central contacts 15b and 15c. This difference, which generates a different difference, is due to the bulges 18 and 19 formed on the periphery of the bar 16.
- FIG. 3 represents a fixed contact, for example 14a or 14b, and two corresponding movable contacts, by example 15a and 15b.
- the distance separating the contacts 14a and 15a is less than the distance between the contacts 14b and 15b.
- the gap separating contacts 14d and 15d is less than the separation distance contacts 14c and 15c, that is to say that the deviations of contacts arranged at both ends of the line contacts, or at both ends of the case, are less than the deviations of the central contacts, which achieves the target.
