  FIG. 3: shows the outline | summary of the state by which the male connector and female connector which concern on embodiment of this invention were fitted. FIG. 4 shows an outline of a state in which the male connector and the female connector according to the embodiment of the present invention are fitted and the interlocking male terminal and the interlocking female terminal are connected.

  First, the opening side of the male connector 10 and the opening side of the female connector 20 are arranged to face each other. Next, as shown in FIG. 3, the male connector 10 is fitted to the female connector 20. Specifically, when the male connector 10 is inserted into the opening of the female connector 20, the male terminal 100 is inserted into the female terminal 200. The interlock male connector 30 is partially inserted into the interlock female connector 35.

  Subsequently, the lever 210 is rotated toward the fitting detection unit 40, and the end of the lever 210 is brought into contact with the fitting detection unit 40. Here, the male connector 10 moves in the direction of the female connector 20 according to the rotation of the lever 210 and the male connector 10 is inserted into the female connector 20, whereby the male connector 10 and the female connector 20 are fitted together. . In this state, the male terminal 100 and the female terminal 200 are fitted together, and the male terminal 100 is electrically connected to the conductor 50a of the cable 50.

  In this case, the interlock male terminal 350 is not yet inserted into the interlock female terminal 300. That is, in this state, the interlock female terminal 300 and the interlock male terminal 350 are not fitted to each other, and the interlock female terminal 300 and the interlock male terminal 250 maintain an open state. ing. Therefore, in this state, the interlock circuit is in an open state, and no current flows between the male terminal 100 and the female terminal 200. Next, the fitting detection unit 40 is moved in a direction in which the interlock female connector 35 and the interlock male connector 30 are fitted together.

  Here, the fitting detection part 40 detects a fitting state. Specifically, the fitting detection unit 40 has a function of detecting whether or not the male connector 10 and the female connector 20 are fitted together. That is, the fitting detection unit 40 is in any state (fitted state) between a state in which the male connector 10 and the female connector 20 are fitted together and a state in which the male connector 10 and the female connector 20 are not fitted together. It has a function to detect whether it is present. For example, the fitting detection unit 40 is held at the non-detection position as shown in FIG. 3 in the process of fitting the male connector 10 and the female connector 20 together. On the other hand, when the male connector 10 and the female connector 20 are fitted together, the fitting detection unit 40 moves to a detection position indicating that the male connector 10 and the female connector 20 are fitted together as shown in FIG. It becomes possible. The non-detection position is, for example, a position where the end 40c of the fitting detection unit 40 exists outside the opening 210a provided in advance in the lever 210. The detection position is, for example, an opening provided in advance in the lever 210. 210a is a position where the end 40c of the fitting detection unit 40 is accommodated.

  Here, the end 40c of the fitting detection unit 40 is inserted into the opening 210a of the lever 210 in a state where the male connector 10 and the female connector 20 are properly fitted. That is, when the state in which the male connector 10 and the female connector 20 are fitted together is not appropriate, for example, the male terminal 100 and the female terminal 200 are in contact with each other while the male terminal 100 and the female terminal 200 are partially in contact with each other. In the case of half-fitting (a state that is not set in advance that is determined to be fitted), the fitting detection unit 40 cannot be moved to the detection position.

  On the other hand, when the fitting between the male connector 10 and the female connector 20 is appropriate, for example, when the fitting is complete (when the fitting state is set in advance), the fitting detection unit 40 detects the fitting. Can be moved to a position. In addition, the case where fitting with the male connector 10 and the female connector 20 is appropriate includes the state in which the male connector 10 and the female connector 20 are completely fitted, and the fitting detection unit 40 is moved to the detection position. The movement includes that the male connector 10 and the female connector 20 can be moved only in a state where they are completely fitted together. Since the fitting detection unit 40 and the interlock female connector 35 are linked via the rod 45, when the fitting detection unit 40 is moved to the detection position, the interlock female connector 35 is moved to the male connector 10 along with this movement. Move to the side. Then, the interlock male connector 30 and the interlock female connector 35 are fitted together as shown in FIG. As a result, the interlock female terminal 300 and the interlock male terminal 350 are electrically connected, and the interlock circuit is closed.

  When the interlock circuit is closed, a signal indicating that the interlock female terminal 300 and the interlock male terminal 350 are electrically connected is supplied to the external control device via the control cable 55. An external control device (not shown) that has received the signal determines that the male connector 10 and the female connector 20 are properly fitted. Then, the external control device works on an external power supply device (not shown) to start supplying power from the power supply device to the electrical connection connector according to the present embodiment.

  When the male connector 10 and the female connector 20 that are fitted to each other are separated (when the male connector 10 is pulled out from the female connector 20), first, the fitting detection unit 40 is moved away from the male connector 10. Thereby, the interlock male terminal 250 is pulled out from the interlock female terminal 300, and the interlock circuit is electrically opened. When the interlock circuit is electrically opened, the external control device to which the control cable 55 is connected determines that the male connector 10 and the female connector 20 can be separated, and the electrical connection connector. Shut off the power supply to

  Thereafter, the male connector 10 and the female connector 20 are separated by rotating the lever 12 toward the male connector 10 and pulling out the male connector 10 from the female connector 20. In the present embodiment, since the interlock circuit is electrically opened and the power supply to the conductor 50a is cut off, the male connector 10 and the female connector 20 are separated. The male connector 10 and the female connector 20 are separated in a state where no current flows between them.

(Effect of embodiment)
The electrical connection connector according to the embodiment of the present invention can close the interlock circuit after the fitting detection unit 40 detects that the male connector 10 and the female connector 20 are properly fitted. In other words, since the interlock female connector 35 is interlocked with the fitting detection unit 40, the interlock detection unit 40 does not detect that the male connector 10 and the female connector 20 are properly fitted to each other. The circuit never closes. Therefore, in a state where the male connector 10 and the female connector 20 are not properly mated, a predetermined signal is not supplied to the external control device via the control cable 55. Current can be prevented from being supplied to the connector. As described above, the electrical connection connector according to the present embodiment can improve the safety of work when the male connector 10 and the female connector 20 are connected.

  Moreover, the electrical connector according to the embodiment of the present invention includes an interlock female connector 35 that operates in conjunction with the fitting detection unit 40 when the male connector 10 and the female connector 20 are separated. The interlock circuit is opened by moving away from the male connector 30 for use. Therefore, the energization between the male terminal 100 and the female terminal 200 as the main energization terminal can be reliably cut off before the male terminal 100 moves relative to the female terminal 200. As a result, abnormal heat generated when the male terminal 100 and the female terminal 200 are separated while being energized and arc discharge can be prevented, so that abnormal friction between the male terminal 100 and the female terminal 200 is prevented. The durability and current-carrying performance of the terminal 100 and the female terminal 200 can be maintained. Furthermore, since the electric current between the male terminal 100 and the female terminal 200 can be interrupted when the male connector 10 and the female connector 20 are separated, the separation work of the male connector 10 and the female connector 20 (pulling work). Safety can be improved.
