Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other. The invention will be described in detail below with reference to the drawings in connection with embodiments.
Fig. 1 is a block diagram of a multi-connector electrical separation switching separation device according to an embodiment of the present invention. As shown in fig. 1, the multi-connector electrical separation switching separation device includes: the power supply comprises a power supply wiring terminal, a switch without a self-locking button, a power supply connection indicator lamp, a peak elimination circuit, a contact element storage bag, a crocodile clip and a plurality of pinhole contact elements; wherein,
the power connection terminal is connected with one end without the self-locking button switch, the other end without the self-locking button switch is connected with one end of the power-on indicator lamp, and the other end of the power-on indicator lamp is respectively connected with the anti-peaking circuit, the crocodile clip and the plurality of pinhole contacts; part of pinhole contacts are connected with the separation connector, and the rest of pinhole contacts are connected with the contact storage bag;
the switching power supply voltage is sent into one end without the self-locking button switch through the power supply wiring terminal, the voltage is switched on to the other end without the self-locking button switch after the self-locking button switch is pressed down, the power supply on indicator lamp is lightened, the corresponding pinhole contact piece applies the voltage to the corresponding point position of the separation connector, and the head and the seat of the separation connector are smoothly separated; the coil without the self-locking button switch is loosened, the separation connector is powered off, and at the moment, the anti-peak current of the coil of the separation connector is released through the anti-peak circuit.
Fig. 1 shows a disconnecting connector disconnecting test equivalent circuit, wherein L is the inductance of an electric disconnecting plug coil, and R2 is the coil resistance. After the Vc voltage is disconnected, because the current of the inductance coil cannot be suddenly changed, the energy in the coil still needs to be released through flowing in the arrow direction, if the internal resistance and the voltage drop of the diode are ignored, and R=R1+R2 is caused, the switch K is disconnected at the moment when the current in the inductance L is Vc/R2, and then the current in the inductance L is provided with
L*(di/dt)+Ri＝0；
The general solution of the visible current i is
i＝Aexp(-Ri/L)。
Since the current cannot be suddenly changed in the inductor, i (0-) =i (0+) =1o.substitution formula i=axp (-Ri/L) yields an integration constant a=io.
Thus, the current i=loxp (-Rt/L) =loxp (-T/T), where lo=vc/R, t=l/R.
The voltages on the resistor and the inductor are respectively:
un＝Ri＝Rloexp(-t/T)；
L＝Ldi；
di＝-Rloexp(-t/T)。
from the above formula, the absolute values of the two are all reduced according to the same exponential law. The induced electromotive force inevitably causes voltage rise at both ends of the inductor along the direction of the current due to the decrease of the current, and the voltage of the inductor should be negative in the selected reference direction, so that a negative sign appears in the formula (3), the current and voltage change curves with time can also see the influence on the circuit after the resistance is increased, and finally the anti-peak voltage is released at the end of the resistor R1 through diode conduction.
The plurality of pinhole contacts includes a miniature pinhole contact, a plurality of 1mm pinhole contacts, and a 0.8mm pinhole contact.
The voltage of the switch power supply is sent to one end of the button switch through the power connection terminal, the other end of the switch is connected with the power connection indicator lamp, and the end is simultaneously connected with the anti-peaking circuit and various contact pieces, and the crocodile clip. The contact insulating storage bag is additionally arranged outside the contact wire to prevent the short circuit of the power supply. The power supply voltage is switched on to the other end after the button switch is pressed down, the power supply switch-on indicator lamp is turned on, and the corresponding contact piece applies voltage to the corresponding point position of the electric connector, namely the actual electric separation voltage value is arranged on the wiring bag of the corresponding electric separation connector, and at the moment, the separation connector is smoothly separated. When the switch is released, the switch is automatically reset, the electric separation voltage is closed, and the anti-peak current of the electric separation coil is released through the anti-peak circuit. The whole electrical separation and falling process is completed.
The steps of using the electrical disconnect switch of the various types of connectors of the present invention are as follows:
(1) The power supply wiring terminals are connected to the positive and negative stages of the power supply. The red binding post connects the positive level of power, and black binding post connects at the negative level of power.
(2) And selecting proper contact elements according to the required separation connectors, and inserting the contact elements at corresponding point positions of the corresponding connectors, inserting the red contact elements into positive stages and inserting the black contact elements into negative stages. And the redundant contact is placed in the contact storage bag, so that the positive and negative-level short circuit of the power supply is prevented.
(3) The voltage to be applied is set on the power supply.
(4) The button switch is pressed, and the power-on indicator lamp is turned on. A voltage is applied to the split connector wiring packages. The connector head and the seat are separated smoothly.
(5) The release button switch and the button spring up automatically, and the disconnection connector is powered off.
(6) The energy of the wire package without the anti-peaking circuit is released through the anti-peaking circuit.
(7) And closing the power supply.

As shown in fig. 2, the anti-peak circuit comprises a resistor R1, an anti-peak diode D, a coil resistor R2 and a separation inductance coil L; the resistor R1 is connected in series with the anti-peak eliminating diode D and then connected in parallel with the split inductor L; the coil resistor R2 is connected between the anti-peaking diode D and the split inductor coil L. The connection relation is as follows: the resistor R1 is connected in series with the anti-peaking diode and in parallel with the separate electrical connector coil.
After the self-locking button switch is pressed down, the voltage is switched on to the other end without the self-locking button switch, the power-on indicator lamp is turned on, the corresponding pinhole contact piece applies the voltage to the corresponding point of the separation connector, the anti-peak eliminating diode D is in a cut-off state, the head and the seat of the separation connector are smoothly separated, the two ends of the inductance coil L are separated at the moment of power failure to generate the multiplied anti-peak voltage, the anti-peak eliminating diode D is in a conduction state, the anti-peak voltage can release the voltage to the resistor R1 through the anti-peak eliminating diode, and the resistor R1 consumes the anti-peak voltage. Through the optimization of different contact interfaces, the quick separation test of multiple types of electric separation connectors can be realized, and the efficiency is high. And the connectors of various types are matched with each other without independently making a separation tool for each type of separation connector.
