  The slider body 47 is formed in a substantially rectangular block shape. The slider body 47 is formed in a shape that matches the slider assembly portion 28 of the third housing 19. In such a slider main body 47, a slide surface 50, a pair of first convex portions 51, and a slide operation portion 52 are formed. The slide surface 50 is a portion corresponding to the lower surface of the slider main body 47 and is formed as a smooth surface that slides on the slide surface 29 of the slider assembly portion 28.

  The pair of first convex portions 51 is guided to the first slide portion 30 as a portion to be inserted into the groove-shaped first slide portion 30 in the slider assembly portion 28 of the third housing 19 and during the slide movement. Formed as a part. The pair of first convex portions 51 are formed in such a shape that, when inserted into the first slide portion 30, the movement in the vertical direction (direction of engagement / disengagement) and the horizontal direction is restricted. A locking recess 53 is formed in each of the pair of first protrusions 51. The locking recess 53 is formed as a portion that is hooked on the slider locking protrusion 31 of the slider assembly portion 28. The slide operation unit 52 is a part corresponding to the upper surface of the slider main body 47 or an edge continuous with the front surface, and is formed as a part operated by a maintenance worker while pressing it, for example.

  The housing insertion portion 48 has a columnar portion 54 that extends straight rearward (extends in the sliding direction) continuously to the rear surface side of the slider main body 47, and a terminal accommodating recess 55 formed on the lower surface side of the columnar portion 54. Reference numeral 56 in the terminal receiving recess 55 indicates a fixing hole. The fixing hole 56 is formed as a part for fixing the fourth terminal 46. In addition, when the 4th terminal 46 is fixed to the housing insertion part 48 using the terminal accommodating recessed part 55 and the fixing hole 56, the part of the housing insertion part 48 has a function as a connector.

  The pair of rotation restricting portions 49 are formed so as to protrude in the left-right direction continuously from the left and right side surfaces of the slider body 47. The pair of rotation restricting portions 49 are formed so as to have a flush portion with the upper surface of the slider body 47. In the present embodiment, the pair of rotation restricting portions 49 are formed in a substantially crank shape in plan view. The pair of rotation restricting portions 49 are respectively formed with a slider facing surface 57 and a second convex portion 58.

  The pair of slider facing surfaces 57 is formed as a smooth surface located on the lower surface of the base end portion of the pair of rotation restricting portions 49. The pair of slider facing surfaces 57 are formed as portions facing the pair of slider facing surfaces 32 in the slider assembly portion 28 of the third housing 19. The pair of second convex portions 58 are formed in a convex shape at the tip portions of the pair of rotation restricting portions 49. The pair of second convex portions 58 are formed as portions guided by the pair of second slide portions 42 of the operation lever 17. Further, the pair of second convex portions 58 are formed as portions that restrict the rotation of the operation lever 17 after being guided by the pair of second slide portions 42.

  The fourth terminal 46 has a pair of electrical contact portions 59 accommodated in the terminal accommodating recess 55 and a press-fit convex portion 60 that is fixed by being inserted into the fixing hole 56, for example, in the shape shown in the figure. In the present embodiment, the fourth terminal 46 is also fixed by a pair of clamping portions 61 (see FIG. 6) formed in the housing insertion portion 48. The pair of electrical contact portions 59 has elasticity and contacts the relay terminal 43 of the movable-side relay signal connector 7. The fourth terminal 46 is fixed to the slider 45 as a portion indirectly connected to the second terminal 14 of the fixed-side signal connector 6.

  Next, the operation of the terminal-equipped slider 4 based on the above configuration and structure will be described with reference to the drawings.

  FIG. 7 is a perspective view showing a state where the slider with terminals is about to be assembled to the movable connector in which the operating lever is in the lying down position, and FIG. 8 is a perspective view showing a state where the slider with terminals is slid from the state of FIG. 9 is a cross-sectional view taken along line AA of FIG. 8, FIG. 10 is a cross-sectional view taken along line BB of FIG. 9, and FIG. 11 is a cross-sectional view showing a state where the sliding movement of the slider with terminal is completed from the state of FIG. 12 and 12 are cross-sectional views taken along the line CC of FIG.

  The drawings excluding FIG. 7 (FIGS. 8 to 12) are not particularly shown, but the movable power connector 3 is engaged with the fixed power connector 2 (in other words, the power circuit D Is on).

  In FIG. 7, in a state where the slider 4 with terminal is to be assembled, the operation lever 17 is in the lying down position (an example). In other words, the lever is extended so that the lever extending direction coincides with the front-rear direction (non-engaging / disengaging direction). At this time, in the movable power connector 3, the entire slider assembly portion 28 of the third housing 19 is exposed. The terminal-equipped slider 4 is arranged so that the housing insertion portion 48 side faces the slider assembly portion 28. When the terminal-attached slider 4 is assembled to the slider assembly portion 28, the following state is obtained.

  7 to 10, the terminal-equipped slider 4 is slid toward the movable relay signal connector 7 by assembling the terminal-equipped slider 4. At this time, the pair of first convex portions 51 of the slider 45 are guided to the pair of first slide portions 30 of the slider assembly portion 28. Further, the slide surface 29 of the slider assembly 28 and the slide surface 50 of the slider 45 slide. Further, the pair of slider facing surfaces 32 of the slider assembly portion 28 and the pair of slider facing surfaces 57 of the slider 45 face each other. In the slider 45, the second convex portion 58 in the pair of rotation restricting portions 49 is guided to the pair of second slide portions 42 of the operation lever 17.

  The slider 45 is first assembled until the locking recess 53 in the pair of first protrusions 51 is hooked and temporarily locked by the slider locking protrusions 31 in the pair of first slide portions 30 of the slider assembly portion 28. . In the temporarily locked state, the fourth terminal 46 of the slider 4 with terminal is not electrically connected to the relay terminal 43 of the movable-side relay signal connector 7.

  11 and 12, when the slider 4 with terminal 4 is slid toward the movable relay signal connector 7 while pushing the slide operation portion 52, the housing insertion portion 48 of the slider 45 and the fourth terminal 46 are moved to the movable relay signal. Insertion into the connector 7 completes the assembly of the slider 4 with terminals. If the operation lever 17 is not in the lying down position, the housing insertion portion 48 and the fourth terminal 46 are not inserted into the movable relay signal connector 7 due to the structure. The fourth terminal 46 of the terminal-equipped slider 4 is electrically connected to the relay terminal 43 of the movable relay signal connector 7, thereby turning on the signal circuit S (see FIG. 1). Therefore, the power supply circuit D (see FIG. 1) becomes conductive. In the operation lever 17, the pair of second slide portions 42 and the pair of second convex portions 58 engage with each other in the vicinity of the pair of rotating shaft portions 34 as the slider 4 with terminal 4 is assembled. Therefore, rotation regulation is made.

  When the slider 4 with terminal is slid in the reverse direction as described above, the electrical connection between the fourth terminal 46 of the slider 4 with terminal and the relay terminal 43 of the movable relay signal connector 7 is released. The signal circuit S is turned off and the power supply circuit D is turned off. When the terminal-equipped slider 4 is moved to the temporary locking position, the rotation restriction of the operation lever 17 is released, and the rotation to the standing state position becomes possible.

  As described above with reference to FIGS. 1 to 12, according to the power shut-off device 1 of the present invention, the slider 45 is included in the configuration, and the fourth terminal 46 is fixed to the slider 45. Therefore, the signal circuit S can be turned on / off not by operating the operating lever 17 but by operating the slider 45 (the operating lever 17 does not need to be slid as in the conventional example). Therefore, it is not necessary to mount the power circuit breaker 1 after securing a large amount of lever slide movement (see dimension P in FIG. 13) as in the conventional example, and as a result, it is possible to reduce the size compared to the conventional example. There is an effect that can be done.

  Further, according to the power shutoff device 1 of the present invention, since the rotation of the operation lever 17 is restricted by the slider 45, the structure of the operation lever 17 and the structure of the rotating shaft portion can be simplified as compared with the conventional example. . Therefore, the effect that it can contribute to size reduction of the power circuit breaker 1 is also produced. Furthermore, according to the power shut-off device 1 of the present invention, the operation of the operation lever 17 can be restricted and permitted simultaneously with the turning on / off of the signal circuit S by the operation of the slider 45. There is also an effect of improving the performance. Furthermore, according to the power shutoff device 1 of the present invention, since the operation lever 17 is not structured to have the on / off portion of the signal circuit S as in the conventional example, the operation lever 17 can be made compact. Therefore, the effect that it can contribute to size reduction of the power circuit breaker 1 is also produced.

  In addition, according to the power shutoff device 1 of the present invention, the groove-shaped first slide portion 30 is formed in the third housing 19 of the movable power connector 3 and the convex shape for sliding the first slide portion 30 is formed. Since the first protrusion 51 is formed on the slider 45, the slider 45 can be slidably assembled only in a predetermined direction with a simple structure. Therefore, the effect that it can contribute to size reduction of the power circuit breaker 1 and the effect that the workability can be improved are achieved.

  Further, according to the power shutoff device 1 of the present invention, the step-shaped second slide portion 42 is formed on the operation lever 17, and the convex second convex portion 58 that slides and moves the second slide portion 42 is a slider. Therefore, the rotation of the operation lever 17 can be restricted with a simple structure. Therefore, there is an effect that it is possible to contribute to the miniaturization of the power circuit breaker 1.

  Furthermore, according to the power shut-off device 1 of the present invention, the housing insertion portion 48 is formed in the slider 45 and the fourth terminal 46 is fixed so as to be positioned in the housing insertion portion 48. With the insertion, the signal circuit S can be turned on by the fourth terminal 46. Therefore, the signal circuit S can be turned on and off with a simple structure, and the power circuit breaker 1 can be reduced in size.

  Furthermore, according to the power shut-off device 1 of the present invention, the fixed-side signal connector is positioned between the operating portion 37 of the operating lever 17 in the lying down position and the third housing 19 in the movable-side power connector 3. 6 and the movable-side relay signal connector 7 are not increased in size, and as a result, an increase in size due to the position of the on / off portion of the signal circuit S can be prevented. Therefore, there is an effect that it is possible to contribute to the miniaturization of the power circuit breaker 1.

  In relation to the present invention, the power circuit breaker 1 includes a slider 45 as this configuration. The slider 45 has a configuration and structure that can simultaneously perform two functions of connector engagement assurance and engagement detection. Further, the slider 45 has a structure that makes the slide movement of the operation lever 17 unnecessary and a structure that restricts rotation.

  It goes without saying that the present invention can be variously modified without departing from the spirit of the present invention.
