FIG. 7 is a cross-sectional view taken along line CC of FIG. FIG. 9 is a front view showing the male connector 11.

  The first protrusion 31 of the holding protrusion 30 a is formed continuously from the holding portion 311 that holds the first wall portion 711 of the contact portion 71 in the male terminal 7 and the holding portion 311, and the contact portion of the male terminal 7. And an extending portion 312 extending toward the opening 510 a (see FIG. 3) of the male outer housing 5 from the tip of 71.

  Similarly, the second projecting piece 32 of the clamping protrusion 30a is formed continuously from the holding portion 321 that holds the second wall portion 712 of the contact portion 71 of the male terminal 7 and the holding portion 321 and is a male terminal. 7 and an extension portion 322 extending toward the opening 510a (see FIG. 3) of the male outer housing 5 from the tip of the contact portion 71.

As shown in FIGS. 8A and 8B, the holding portion 311 of the first projecting piece 31 has the inner surface 311 a of the holding portion 311 facing the outer surface 711 b of the first wall portion 711. Similarly, in the holding portion 321 of the second projecting piece 32, the inner surface 321 a of the holding portion 321 faces the outer surface 712 b of the second wall portion 712. In the present embodiment, the inner surface 311a of the holding portion 311 and the outer surface 711b of the first wall portion 711, and the inner surface 321a of the holding portion 321 and the outer surface 712b of the second wall portion 712 are in contact with each other. Therefore, the distance H ₀ between the contact portion 71 of the male terminal 7 and the clamping protrusion 30a in the first direction is substantially zero, and is an interval that makes it impossible to contact the finger and the test finger 8 with the contact portion 71. is there.

  The front end surface 713b of the contact portion 71 of the male terminal 7 includes a step surface 31a formed between the holding portion 311 and the extending portion 312 and a step surface formed between the holding portion 321 and the extending portion 322. It faces 32a. In the present embodiment, the front end surface 713b of the contact portion 71 is in contact with the step surface 31a and the step surface 32a.

  As shown in FIG. 7, the inner surface 312a and the inner surface 322a of the extending portion 312 of the first protruding piece 31 and the extending portion 322 of the second protruding piece 32 face each other. That is, as shown in FIG. 8C, the first wall portion 711 and the second wall portion 712 are formed by extending the extended portion 312 of the first protruding piece 31 and the extended portion 322 of the second protruding piece 32. There is no intervening between.

The distance W between the inner surface 312a of the extending portion 312 of the first protruding piece 31 and the inner surface 322a of the extending portion 322 of the second protruding piece 32 (the interval between the first protruding piece 31 and the second protruding piece 32). ) Is formed to be narrower than the diameter D ₂ (see FIG. 6) of the second cylindrical portion 82 of the test finger 8, whereby the contact of the finger with the contact portion 71 of the male terminal 7 is suppressed. That is, the interval W between the first protruding piece 31 and the second protruding piece 32 in the first direction is an interval that suppresses the contact of fingers with the contact portion 71 of the male terminal 7. In addition, the distance L from the tip of the extended portion 312 of the first protruding piece 31 and the extended portion 322 of the second protruding piece 32 to the end of the notch 713a is determined so that the tip of the fingertip portion 83 of the test finger 8 is male. The length is set such that the contact portion 71 of the terminal 7 cannot be contacted.

As shown in FIG. 9, there is a _first gap between the pinching protrusion 30 a ₁ and the parallel protrusion 30 b ₁ , between the pinching protrusion 30 a ₂ and the interlocking male connector 9, and between the pinching protrusion 30 a ₃ and the parallel protrusion 30 b ₃ . the interval in the second direction is _{H 1,} respectively, between the clamping projections 30a ₁ between the parallel projections 30b _2, between the clamping projections 30a ₂ and the parallel projections 30b _5, and the clamping protrusion 30a ₃ and the parallel projection 30b ₄ When the distance in the second direction is H ₂ , the distances H ₁ and H ₂ are formed narrower than the width of the fingers. More specifically, the intervals H ₁ and H ₂ are formed narrower than the diameter D ₂ (see FIG. 6) of the second cylindrical portion 82 of the test finger 8.

Further, in the present embodiment, as shown in FIG. 8, the entire outer surfaces 711b and 712b of the first and second wall portions 711 and 712 of the male terminal 7 are covered with the inner surfaces 311a and 321a of the holding portions 311 and 321. In other words, the distance between the contact portion 71, the clamping protrusions 30a ₁ and 30a ₃ and the interlock male connector 9 in the second direction is equal to the distance H ₁ . Further, the distance H ₃ between the contact portion 71 and the clamping protrusions 30a ₁ , 30a ₄ , 30a ₅ in the second direction is slightly larger than the distance H ₂ . The distance H ₃ is formed narrower than the width of the fingers is formed narrower than a diameter D ₂ of the second cylindrical portion 82 of the specific test finger 8.

Thereby, the contact of the finger to the contact part 71 of the male terminal 7 is suppressed. That is, the distances H ₁ and H ₃ between the contact portion 71 of the male terminal 7 and the parallel protrusion 30b and the interlock male connector 9 in the second direction suppress the contact of fingers with the contact portion 71 of the male terminal 7. It is an interval.

These intervals H ₁ , H ₂ , H ₃ are intervals that disable the contact of the finger with the contact portion 71 and the contact of the test finger 8. Here, the interval at which the finger cannot be contacted means, for example, that the finger contacts the contact portion 71 even when an adult finger is placed sideways from the opening 510 a side of the male outer housing 5 toward the contact portion 71 side. The interval is such that it is not, more specifically, for example, 4 to 8 mm.

Therefore, the contact of the finger to the male terminal 7 is suppressed by the parallel protrusion 30 b and the interlock male connector 9. In the present embodiment, the intervals H ₁ and H ₂ have the same dimensions (H ₁ = H ₂ ).

(Interlock circuit configuration)

It is sandwiched between the contact 922 and contacts the upper contact 921 and the lower contact 922, respectively. In addition, the male terminal contacts the first female terminal 91 in the same manner. By connecting the male terminal of the interlock female connector 20 to the first female terminal 91 and the second female terminal 92, the first female terminal 9 and the interlock female connector 20 are connected to each other. The female terminal 91 and the second female terminal 92 are conducted (short-circuited), and the interlock circuit is closed. That is, the male terminal functions as a short bar that short-circuits the first female terminal 91 and the second female terminal 92.

Thereby, the interlock circuit is closed, and the first female terminal 91 and the second female terminal 92 of the interlock male connector 9 and the male terminal of the interlock female connector 20 are electrically connected. A signal is output to an external control device (not shown) via the first signal line 910 and the second signal line 920. And a control apparatus works on an inverter (not shown) and the electric power is supplied to the connector apparatus 1 (refer FIG. 1).

As a result, the interlock circuit is electrically opened, and the control device to which the first signal line 910 and the second signal line 920 are connected is connected to the first female terminal 91 and the first female terminal 91 of the interlock male connector 9. It is determined that the electrical connection between the second female terminal 92 and the male terminal of the interlock female connector 20 has been released, and the power supply to the connector device 1 is interrupted by acting on the inverter.
