よび電気的に接続される。A fitting recess 31 for fitting the male connector 4o is formed in the female connector 30, and mounting pieces 32 and 32 each having a mounting hole 32a are provided on both sides of the female connector 30, and fitting pieces 32 and 32 are provided on both sides of the connector 30 to fit into the male connector 4o. Engagement holes 33 communicating with the mating recesses 31 are formed respectively (only one side is shown in the figure). On the other hand, flexible engagement claws 43 are formed on both sides of the male connector 40 in correspondence with the engagement holes 33 of the female connector 3o (only one side is shown in the figure),
One end of a tension wire 41 is attached to the rear end surface, and an attachment ring 42 is attached to the other end of the tension wire 41. The female connector 3o and the male connector 40 are connected by inserting the front end of the male connector 40 into the fitting recess 31 of the female connector 3o. As a result, the engaging claw 43 of the male connector 4o
is pushed by the inner surface of the fitting recess 31 of the female connector 30 and once bends inward, then elastically restores itself and engages with the engagement hole 33, thereby establishing a connection between the female connector 30 and the male connector 4o. In this way, harness 7a and harness 7b are mechanically and electrically connected.

１７が損傷した場合でも、ショートを防止できる。According to this electric circuit interrupting device, when the driver D is pressed against the steering wheel 6 due to a vehicle collision, the bracket 4 is removed from the bolt 5 and the steering column tube 3 is removed as shown by the imaginary lines in FIGS. 1 and 2. Displace it forward like this. Then, along with this displacement, the male connector 40 is pulled forward via the tension wire 41,
The tensile load causes the engagement claw 43 to be pulled out of the engagement hole 33, and the connection between the male connector 40 and the female connector 30 is released. As a result, the electric circuit between the key cylinder 8 and the main circuit M is cut off, the main circuit M is disabled, and the driving of electric devices such as the ignition coil 9 and the fuel bomb 11 is immediately stopped. When the driving of the ignition coil 9 is stopped, the driving of the engine is stopped, and the exhaust temperature is reduced. Moreover, when the drive of the fuel bomb 11 is stopped, the supply of fuel to the fuel piping 12 is stopped, and even if the fuel piping 12 is damaged, fuel leakage can be suppressed to a minimum. Furthermore, even if the electrical harness 17 is damaged, short circuits can be prevented.

Of course, it is also possible to apply this invention to other parts. In addition to the above-mentioned parts, examples of parts having such a mutual relationship include parts such as a bumper stay fender panel, radiator grille, bonnet, and engine mount, and corresponding parts on the vehicle body.
