  A pedestal 12 on which the first electrode 4 is mounted is integrally formed on the bottom wall 5d of the first housing 5 so as to protrude upward (inwardly) from the inner wall of the bottom wall 5d. The pedestal 12 is provided with a fastening member 14 made of metal having a fastening hole 13 for fastening a screw for screwing.

  A notch 15 opened on the insertion side of the first electrode 4 is formed in the upper upper wall 5c of the fastening member 14, and a screw is introduced from the notch 15 to perform screwing operation. It is done.

  The pedestal 12 is not formed at the end of the bottom wall 5d on the connector portion 3 insertion side, and a step 16 is formed between the pedestal 12 and the bottom wall 5d. The step 16 (the surface on the side of the base 12 where the connector portion 3 is inserted) plays a role of pushing the terminal cover 30 described later into the second housing 8.

  Further, on both sides in the width direction of the pedestal 12 and at the central portion in the width direction of the pedestal 12, wall portions 17 projecting upward are formed. The wall portion 17 serves as a guide when the first electrode 4 is accommodated in the first housing 5 and increases the edge surface distance between the connection portions of the first electrode 4 and the second electrode 7 to cause a short circuit or the like. Plays a role in suppressing

  A gap 19 is formed between the pedestal 12 and the side walls 5a and 5b (between the wall portion 17 and the side walls 5a and 5b). When the two housings 5 and 8 are fitted, the gap 19 is formed. The distal end portion (projecting portion 35) of the inner housing 8b in the second housing 8 is accommodated.

  A plate-like locking release piece 18 is integrally formed on the wall portions 17 formed on both sides so as to protrude from the wall portion 17 to the insertion side of the connector portion 3.

And a guide portion 40 for guiding the slide.

  Since the lance 39 is formed in a plate shape, its mechanical strength is relatively low. Therefore, in the present embodiment, in order to suppress breakage of the lance 39, the lance 39 is formed at a position inside the outer surface of the guide portion 40 in the width direction. In other words, the lance 39 is provided so as not to project outward beyond the outer surface of the second housing 8.

  The connector portion 3 is provided slidably in the second housing 8 and has a terminal cover 30 at least a part of which is provided so as to be accommodated in the second housing 8. The terminal cover 30 is made of an insulator, and is disposed so as to cover the entire second electrode 7 when the terminal cover 30 is not housed, that is, when the terminal cover 30 is advanced from the second housing 8. In the present embodiment, the terminal cover 30 is slidably provided on the inner housing 8b, and is slidable along the fitting direction (longitudinal direction).

  The terminal cover 30 is formed in a substantially rectangular shape, and an electrode insertion hole 36 for passing the second electrode 7 is formed on the surface on the front side in the fitting direction. Moreover, the fitting direction back of the terminal cover 30 is opened, and it is comprised so that the cable 6 may be extended from the said opening. Here, two terminal covers 30 are provided independently so as to correspond to the two second electrodes 7.

  The terminal cover 30 is disposed so as to project forward in the fitting direction further than the flange portion 31 when the terminal cover 30 is disposed so as not to be accommodated and to cover the second electrode 7. Further, even when the terminal cover 30 is accommodated in the second housing 8, a part (tip portion) of the front in the fitting direction is arranged outside the second housing 8.

  Further, the connector portion 3 has a locking means 37 that locks the terminal cover 30 in a state of covering the second electrode 7 and restricts the sliding of the terminal cover 30 into the second housing 8.

  In the present embodiment, the locking means 37 is provided on the second housing 8 with the locking projection 38 provided on the terminal cover 30 so as to protrude outward (here side), and the terminal cover 30 is provided. And a lance 39 having a claw 39a that is engaged with the engagement projection 38 in a state in which the second electrode 7 is covered.

  The locking projection 38 is formed on the front end of the terminal cover 30 in the fitting direction, and is formed to project laterally from the side surface of the terminal cover 30.

  The claws 39 a are provided so as to protrude inward in the width direction from the tip (end in the fitting direction) of the lance 39, and the terminal cover 30 is pulled out of the second housing 8, When the electrode 7 is covered with the terminal cover 30, it is locked by the locking projection 38 to restrict the movement of the terminal cover 30 in the fitting direction to the rear.

  Further, in the present embodiment, the claw portion 39a is provided only at the upper portion of the tip end portion of the lance 39, and in the lower portion at the tip end portion of the lance 39, the claw portion 39a inclines inwards away from the terminal cover 30 A locking release slope 41 is formed. The locking release slope 41 is formed by forming a notch in the lower part of the tip of the lance 39.

  When the two housings 5 and 8 are fitted, the unlocking piece 18 (see FIG. 2 (b)) abuts on the unlocking slope 41 and the second housing 8 along the unlocking slope 41. It is pushed inside. As a result, the lance 39 is pushed outward by the locking release piece 18 (the projection 18a), the locking by the claw 39a is released, and the terminal cover 30 can slide rearward in the fitting direction. In the connector 1, the terminal cover 30 whose locking has been released is configured to be pushed into and accommodated in the second housing 8 by the step 16 of the first housing 5.

  On the upper and lower surfaces of the distal end portion of the terminal cover 30, an outwardly projecting protrusion 42 is formed. When the two housings 5 and 8 are fitted, the withdrawal projection 42 is engaged with the withdrawal locking piece 20 (see FIG. 2B), and when the two housings 5 and 8 are disengaged. , The terminal cover 30 plays a role of automatically pulling out the inside of the second housing 8. The terminal cover 30 is formed so as to be held so as to be sandwiched from above and below by forming the withdrawal projections 42 on the upper and lower sides of the terminal cover 30 and sandwiching the terminal cover 30 with the opposing withdrawal locking pieces 20. The piece 20 can hold the terminal cover 30 firmly and enables the terminal cover 30 to be pulled out of the second housing 8 reliably.

  A chamfering process is performed on a corner of the drawing for drawing 42 so that the locking piece for drawing 20 can easily get over when the two housings 5 and 8 are fitted. Further, on both sides of each pulling out protrusion 42, locking piece guide protrusions 43 for guiding the pulling out locking piece 20 when the two housings 5 and 8 are fitted are formed.

  In the present embodiment, the projection for extraction 42 is formed on the terminal cover 30 of the portion disposed outside the second housing 8 when housed in the second housing 8, and the two housings 5 and 8 are fitted together Even when the terminal cover 30 is accommodated in the second housing 8, the locking of the pullout projection 42 and the pullout locking piece 20 is not released.

  Further, at the proximal end portion of the terminal cover 30, a retaining projection 44 is formed which prevents the terminal cover 30 from being detached from the second housing 8 (inner housing 8b). The retaining projections 44 are formed to project outward from the upper and lower surfaces of the terminal cover 30, and can slide in grooves (notches) 45 formed in the inner housing 8b along the longitudinal direction. It is housed. The retaining projection 44 and the groove 45 have both the role of retaining the terminal cover 30 and the role of guiding the slide of the terminal cover 30.

  A guide wall 40a which protrudes inward in the width direction from the outer end in the height direction is integrally formed on the guide portion 40 of the protrusion 35 in the inner housing 8b. The side end of the terminal cover 30 is sandwiched by the guide wall 40a from above and below, whereby the slide of the terminal cover 30 is guided. Thereby, when fitting both housings 5 and 8, it is suppressed that the terminal cover 30 inclines, and the terminal cover 30 becomes slidable smoothly.

(Connection between terminal block 2 and connector 3)
When connecting the terminal block portion 2 and the connector portion 3, first, as shown in FIGS. 8A and 8B, the two housings 5 and 8 are opposed to each other, and the second housing 5 is disposed in the first housing 5. Press 8 in.

At the same time, the locking release piece 18 abuts on the locking release slope 41 of the lance 39.

  When the second housing 8 is further pushed in, as shown in FIGS. 11A and 11B, the unlocking piece 18 is pushed along the unlocking slope 41 into the second housing 8 and accordingly Thus, the projection 18a of the locking release piece 18 pushes the lance 39 outward in the width direction, and the locking of the terminal cover 30 by the claw 39a is released.

  When the second housing 8 is further pushed in, the terminal cover 30 is pushed into the second housing 8 by the step 16 of the first housing 5 and the second electrode 7 passes through the electrode insertion hole 36 and the pedestal 12 of the terminal block 2 It is inserted at the top. Thereafter, after both flanges 10 and 31 abut, both flanges 10 and 31 are bolted and both electrodes 4 and 7 are screwed to complete connection between terminal block 2 and connector 3 . In the present embodiment, a member for closing the notch 15 of the terminal block 2 is not particularly provided, but the portion on the first electrode 4 insertion side of the flange portion 10 of the terminal block 2 is in the housing of the device. Because it is housed, it is not exposed to the outside, and the touch protection structure is maintained.

  When releasing the connection between the terminal block portion 2 and the connector portion 3, the terminal cover 30 is automatically pulled out of the second housing 8 by the locking of the pull-out locking piece 20 and the pull-out projection 42, With the terminal cover 30 covering the second electrode 7, the claw 39 a of the lance 39 is engaged with the engagement projection 38. Thereafter, the pullout locking piece 20 rides over the pullout projection 42 and the lock is released, and the connector portion 3 is detached from the terminal block portion 2.

  As described above, in the connector 1 according to the present embodiment, the second electrode 7 is not always exposed between the two housings 5 and 8 even during the connection operation, and the safety of the worker can be ensured. It is possible.

  The terminal cover 30 is automatically pulled out of the second housing 8 when the two housings 5 and 8 are released by urging the terminal cover 30 forward with an elastic member such as a spring. In this case, both the housings 5 and 8 are fitted while opposing the biasing force of the elastic member, which increases the load on the operator during the connection operation. In order to reduce the load on the worker during the connection operation, the biasing force of the elastic member must be reduced. In this case, the terminal cover 30 may not be pulled out reliably. As in the present embodiment, by configuring the terminal cover 30 to be pulled out from the inside of the second housing 8 by the locking of the pullout locking piece 20 and the pullout projection 42, the connection operation is facilitated, and The terminal cover 30 can be pulled out with certainty.
