The locking receiving portions 92A, 82B provided on the adjacent lower insertion portions 6 and the locking pieces 91A, 81B provided on the adjacent upper insertion portions 7 are arranged in an inverted manner about the vertical direction Z (i.e., the locking pieces are arranged to be the same and the locking receiving portions are arranged to be the same).

[0037] In the second wire insertion portion 3B and the third wire insertion portion 3C (the adjacent wire insertion portions), the locking receiving portions 82B, 92C provided on the adjacent lower insertion portions 6 and the locking pieces 81B, 91C provided on the adjacent upper insertion portions 7 are arranged in an inverted manner about the axis P2, which is the vertical direction Z (the direction in which the first insertion portion and the second insertion portion are assembled) (i.e., the locking pieces are arranged to be the same locking receiving portions). The locking pieces 91B, 81C provided on the adjacent lower insertion portions 6 and the locking receiving portions 92B, 82C provided on the adjacent upper insertion portions 7 are arranged in an inverted manner about the vertical direction Z (i.e., the locking pieces are arranged to be the same locking receiving portions).

[0038] When assembling the rear holder 1 having the above-described configuration, as shown in Figures 3 and 5, three electric wires 11 are positioned between the lower member 1A and the upper member 1B, and the lower member 1A (or the upper member 1B) is moved closer to each other so that the lower divided surface 10A and the upper divided surface 10B are brought closer to each other.

[0039] Meanwhile, as the movement continues, the tip of the right locking piece 81A of the first wire insertion portion 3A comes into contact with the right abutment surface of the right locking receiver 82A, and as the movement continues, the right locking piece 81A is positioned between the first front overhang 84 and the first rear overhang 85. As a result, the right locking piece 81A becomes unable to move in the front-to-rear direction X between the first front overhang 84 and the first rear overhang 85, and the right locking piece 81A is locked by the right locking receiver 82A.

[0040] On the other hand, as the movement continues, the tip of the left locking piece 91A of the first wire insertion portion 3A comes into contact with the left abutment surface 93 of the left locking receiving portion 92A, and as the movement continues, the left locking piece 91A is positioned between the second front overhanging portion 94 and the second rear overhanging portion 95. As a result, the left locking piece 91A becomes unable to move in the front-rear direction X between the second front overhanging portion 94 and the second rear overhanging portion 95, and the left locking piece 91A is locked by the left locking receiving portion 92A.

[0041] Similarly to the first wire insertion portion 3A, the tip of the right-side locking piece 81B of the second wire insertion portion 3B contacts the right-side abutment surface of the right-side locking receiving portion 82B, so that the right-side locking piece 81B is locked to the right-side locking receiving portion 82B, and the tip of the left-side locking piece 91B contacts the left-side abutment surface 93 of the left-side locking receiving portion 92B, so that the left-side locking piece 91B is locked to the left-side locking receiving portion 92B.

[0042] Similarly to the first wire insertion portion 3A, the tip of the right-side locking piece 81C of the third wire insertion portion 3C contacts the right-side abutment surface of the right-side locking receiving portion 82C, so that the right-side locking piece 81C is locked to the right-side locking receiving portion 82C, and the tip of the left-side locking piece 91C contacts the left-side abutment surface 93 of the left-side locking receiving portion 92C, so that the left-side locking piece 91C is locked to the left-side locking receiving portion 92C.

[0043] As a result, each electric wire 11 is sandwiched vertically between the upper insertion portion 7 and the lower insertion portion 6. In this manner, the electric wire insertion portions 3A, 3B, 3C (3) are assembled, and the rear holder 1 supporting the three electric wires 11 is also assembled.

[0044] When the rear holder 1 is attached to the connector housing, the three electric wires 11 are inserted into the connector housing, and the rear holder 1 is positioned at the rear X2 of the connector housing, and the rear holder 1 approaches the connector housing, and the lower member 1A and upper member 1B are simultaneously assembled to the connector housing. In this way, the rear holder 1 is attached to the connector housing.

[0045] According to the above-described embodiment, the locking portions 8A, 8B, 8C (8), 9A, 9B, 9C (9) are provided to assemble the lower insertion portion 6 (first insertion portion) and the upper insertion portion 7 (second insertion portion) to each other, and the locking portions 8, 9 include locking pieces 81A (91A), 91B (81B), 81C (91C) that protrude from one of the lower insertion portion 6 and the upper insertion portion 7 toward the other, and locking pieces 81A (91A), 91B (81B), 81C (91C) that are provided on the other of the lower insertion portion 6 and the upper insertion portion 7. By providing locking receiving portions 82A (92A), 92B (82B), 82C (92C) that lock 1C (91C) so that it cannot move in the front-rear direction X (the direction in which the electric wires 11 extend), even if a load is locally applied to only one of the lower member 1A and the upper member 1B (two members), the lower member 1A and the upper member 1B are restricted from being relatively displaced in the front-rear direction X, and the lower member 1A and the upper member 1B are assembled to the connector housing simultaneously. This prevents only one of the lower member 1A and the upper member 1B from being assembled to the connector housing during assembly, improving the ease of assembly to the connector housing.

[0046] The locking portions 8 and 9 include locking pieces 81A (91A), 91B (81B), and 81C (91C) that protrude from one of the lower insertion portion 6 and the upper insertion portion 7 toward the other, and locking receiving portions 82A (92A), 92B (82B), and 82C that are provided on the other of the lower insertion portion 6 and the upper insertion portion 7 and lock the locking pieces 81A (91A), 91B (81B), and 81C (91C) so that they cannot move in the front-rear direction X (the direction in which the electric wire 11 extends). (92C), even if a load is applied locally to only one of the lower member 1A and the upper member 1B (two members), the load is transmitted from the locking pieces 81A (91A), 91B (81B), and 81C (91C) to the locking receiving portions 82A (92A), 92B (82B), and 82C (92C) and is dispersed throughout the lower member 1A and the upper member 1B, thereby improving the strength against the pull-out load.

[0047] Furthermore, the wire insertion portions 3A, 3 have a pair of locking portions 8A, 9A, and of the pair of locking portions 8A, 9A, locking portion 8A (one side) has a locking piece 81A provided on the lower insertion portion 6 (one side) of the lower insertion portion 6 (first insertion portion) and the upper insertion portion 7 (second insertion portion), and a locking receiving portion 82A provided on the upper insertion portion 7 (the other side) of the lower insertion portion 6 and the upper insertion portion 7, and locking portion 9A (the other side) of the pair of locking portions 8A, 9A has a locking piece 91A provided on the upper insertion portion 7 (the other side) of the lower insertion portion 6 and the upper insertion portion 7, and a locking receiving portion 92A provided on the lower insertion portion 6 (one side) of the lower insertion portion 6 and the upper insertion portion 7.

[0048] Furthermore, the wire insertion portions 3B, 3 have a pair of locking portions 8B, 9B, and of the pair of locking portions 8B, 9B, locking portion 8B (one side) has a locking piece 91B provided on the lower insertion portion 6 (one side) of the lower insertion portion 6 (first insertion portion) and the upper insertion portion 7 (second insertion portion), and a locking receiving portion 92B provided on the upper insertion portion 7 (the other side) of the lower insertion portion 6 and the upper insertion portion 7, and locking portion 9B (the other side) of the pair of locking portions 8B, 9B has a locking piece 81B provided on the upper insertion portion 7 (the other side) of the lower insertion portion 6 and the upper insertion portion 7, and a locking receiving portion 82B provided on the lower insertion portion 6 (one side) of the lower insertion portion 6 and the upper insertion portion 7.

[0049] Furthermore, the wire insertion portion 3C, 3 has a pair of locking portions 8C, 9C, and of the pair of locking portions 8C, 9C, the locking portion 8C (one side) has a locking piece 81C provided on the lower insertion portion 6 (one side) of the lower insertion portion 6 (first insertion portion) and the upper insertion portion 7 (second insertion portion), and a locking receiving portion 82C provided on the upper insertion portion 7 (the other side) of the lower insertion portion 6 and the upper insertion portion 7, and the locking portion 9C (the other side) of the pair of locking portions 8C, 9C has a locking piece 91C provided on the upper insertion portion 7 (the other side) of the lower insertion portion 6 and the upper insertion portion 7, and a locking receiving portion 92C provided on the lower insertion portion 6 (one side) of the lower insertion portion 6 and the upper insertion portion 7. This allows the load to be distributed more sufficiently over the entire lower member 1A and the entire upper member 1B, even if a load is locally applied to only one of the lower member 1A and the upper member 1B (two members).

[0050] Furthermore, the locking pieces 81A, 91B, 91A, 81B and the locking receiving portions 82A, 92B, 92A, 82B of adjacent pairs of wire insertion portions 3A, 3B among the multiple wire insertion portions 3A, 3B, 3C are arranged in an inverted manner about an axis P1, which is the vertical direction Z (the direction in which the first insertion portion and the second insertion portion are assembled). Furthermore, the locking pieces 81B, 91C, 91B, 81C and the locking receiving portions 82B, 92C, 92B, 82C of adjacent pairs of wire insertion portions 3B, 3C among the multiple wire insertion portions 3A, 3B, 3C are arranged in an inverted manner about an axis P2, which is the vertical direction Z (the direction in which the first insertion portion and the second insertion portion are assembled). This allows the lower member 1A and the upper member 1B to be assembled even more firmly.

[0051] The present invention is not limited to the above-described embodiment, but includes other configurations that can achieve the object of the present invention, and the following modifications are also included in the present invention.
