<Embodiment 1>
A first embodiment of the present invention will be described below with reference to FIGS. The assembly of this embodiment includes one housing 10 (a base member which is a constituent element of the present invention) and one lever 20 (which is a constituent element of the present invention) that can be assembled to the housing 10 in two different forms. A lever-type connector X configured to include a certain assembling member), and is adapted to be fitted into and detached from the mating connector Y by operation of the lever 20.

  The housing 10 is formed by integrally molding a terminal holding portion 11 having a block shape that is long in the left-right direction and a rectangular tubular fitting portion 12 that surrounds the terminal holding portion 11 from front, rear, left, and right. The outer periphery of the upper end and the upper end of the cylindrical fitting part 12 are connected. In the rectangular cylindrical fitting space 13 between the terminal holding part 11 and the cylindrical fitting part 12, the hood part Ya of the mating connector Y is fitted from below. A mounting space 14 having a vertically long slit-like cross section penetrating in the left-right direction is formed on both front and rear wall portions of the cylindrical fitting portion 12. The attachment space 14 communicates with the fitting space 13 at the center position in the left-right direction, and the cam pin Yb of the mating connector Y enters the communication portion 15.

  The outer wall portion outside the mounting space 14 in both the front and rear wall portions of the cylindrical fitting portion 12 is covered with cover portions 16F and 16R (selective display means which is a constituent element of the present invention) that form a square in a side view. It has become. Of the two front and rear cover parts 16F and 16R, the front cover part 16F has a window hole 17 that opens in a horizontal rectangle by notching the center position in the left-right direction (selection that is a constituent element of the present invention). Display means). The window hole 17 is formed only in the front cover portion 16F, and is not formed in the rear cover portion 16R.

  The lever 20 is formed by integrally forming two sliders 21a and 21b having a rectangular plate shape and a connecting portion 22 that connects one end portion (base end portion) of the sliders 21a and 21b in the left-right direction. Is. The sliders 21a and 21b are formed with cam grooves 23 that extend obliquely from the lower surface of the tip end portion (the end portion opposite to the connecting portion 22) toward the center position in the left-right direction. In addition, on the outer surfaces of the two sliders 21a and 21b, there are engraved marks 24a and 24b (identifiers that are constituent elements of the present invention) at positions that are the center in the left-right direction and have a height corresponding to the window hole 17 of the housing 10. ) Is formed. The markings 24a and 24b are formed as the lever 20 is molded, and the marking 24a ("AAAAAA" in this embodiment) attached to one slider 21a and the other slider 21b. The mark 24b ("BBBBB" in the present embodiment) to be attached has a character arrangement different from each other.

  The lever 20 can be assembled in a symmetrical manner with respect to the housing 10. That is, as shown in FIG. 9, the sliders 21 a and 21 b are fitted into the mounting space 14 from the right side of the housing 10 in the direction in which the connecting portion 22 is located at the right end, and the connecting portion 22 is connected as shown in FIG. 1. Assembly is possible in such a manner that the sliders 21 a and 21 b are fitted into the mounting space 14 from the left side of the housing 10 in a direction in which the portion 22 is located at the left end.

  In any assembly form, first, the lever 20 has an initial position (see FIG. 2) in which the inlet of the cam groove 23 opened on the lower surface of the tip of the sliders 21a and 21b corresponds to the communication portion 15 of the cylindrical fitting portion 12. Temporarily). At this initial position, the hood portion Ya of the mating connector Y is shallowly inserted into the fitting space 13 and the cam pin Yb on the outer surface of the hood portion Ya is inserted into the communication portion 15 and the inlet of the cam groove 23. From this state, if the connecting portion 22 is grasped and the lever 20 is pushed to the tip side, the sliders 21a and 21b are translated in the left-right direction (direction perpendicular to the mating direction with the mating connector Y) in the mounting space 14. As the sliders 21a and 21b move, the hood portion Ya is drawn into the fitting space 13 (pulled up) by the engagement between the cam groove 23 and the cam pin Yb. When the lever 20 reaches the fitting position (see FIGS. 1 and 9), the fitting of both the connectors X and Y is completed.

  Now, in a state where both connectors X and Y are fitted, it is possible to identify which assembly form the lever 20 is in. That is, when the lever 20 is assembled from the right side of the housing 10, the "AAAAAA" stamp 24a of one (front side) slider 21a is visible from the outside in the window hole 17 of the front cover 16F. In contrast, the other (the slider 21b located on the rear side) and the “BBBBB” mark 24b on the slider 21b are covered by the rear cover portion 16R and cannot be seen. On the contrary, when the lever 20 is assembled from the left side of the housing 10, the marking 24 b of “BBBBB” is exposed in the front window hole 17 so as to be visible from the outside, whereas “AAAAA” The stamp 24a is covered with the rear cover portion 16R and cannot be visually observed.

  The lever-type connector X (assembly) of the present embodiment allows the lever 20 to be assembled to the housing 10 in two different forms, and the lever 20 is assembled with the two levers 20 to the housing 10. Two markings 24a and 24b corresponding to the form are attached, and in the state where the lever 20 is assembled to the housing 10, only the markings 24a and 24b corresponding to the assembly form are exposed, and other assembly forms are provided. Selective display means for covering the markings 24a and 24b corresponding to the cover 20 is provided, and the selective display means includes cover portions 16F and 16R for covering the sliders 21a and 21b of the lever 20 in the assembled state of the lever 20. In the state where the lever 20 is assembled, a window hole that exposes only the marking 24a or 24b corresponding to the assembled form to the outer surface side. It is constituted by a 7. By adopting such a configuration, only the corresponding marks 24a and 24b are displayed according to the assembling form. Therefore, the lever-type connector in which the lever 20 is assembled from the right side and the lever 20 is assembled from the left side. A lever-type connector can be easily and reliably identified.
