To provide erroneous connection prevention measures of a jumper coupler, implemented by a simple operation while maintaining fitting condition between a jumper receptacle and a jumper plug without causing any human errors during coupling work.
In a jumper receptacle 10 for a control circuit disposed on the left side of a vehicle where car body wiring 100 for the control circuit and car body wiring 100 for an auxiliary circuit are mounted side by side, a long member 18 having a male screw part formed at its tip is used instead of a screw 15 for the left through-hole 13a of an insulation stand 13. The jumper receptacle 10 for the auxiliary circuit disposed on the right side is symmetrical with the jumper receptacle 10 for the control circuit. In the jumper plug 20 for the control circuit, a long member 28 having a male screw part formed at its tip is used instead of a screw 25 for the right through-hole 23b of an insulation stand 23. The jumper plug 20 for the auxiliary circuit is symmetrical with the jumper plug 20 for the control circuit.
