To make it possible to prevent a cable from being loosen as the cable is puled up by bending a cable which enters a terminal housing by way of a slot in S shape at a swollen area of the terminal housing and then mounting the cable on a screw-shaped terminal.

When a circuit board support plate 315 is inserted into a circuit board housing 310, a tab 312a is inserted into a notch 307 and various tabs 312, which are projected from he edge of a support plate 315 are respondingly inserted into the notchs of the circuit board housing 310. When the upper part 306 of a terminal housing 330 and a base plate 305 are fitted in, the housing receiving a cable 350 by way of a cable slot 360 a wire of the cable 350 is mounted on a ribbon conductor 343 with a terminal screw 341. The cable 350 is bent in S shape with a ridge 339 of the upper portion and a ride 333 of the base plate 305.
