Abstract

Provided is a cage for a connector, the cage being configured as a module and making it possible, through a simple configuration, to adapt to the number of ports of a connector. The cage for a connector is provided with: a top cover 7 having a tip plate 7a and a first side plate 7b formed by folding the top cover 7 at a right angle along a first folding line 7c extending in a longitudinal direction D1 so that the lateral cross-section has an L-shape; and a bottom cover 9A having a bottom plate 9a and a second side plate 9b formed by folding the bottom cover 9A along a second folding line 9c extending in the longitudinal direction D1 so that the lateral cross-section has an L-shape. The top cover 7 and the bottom cover 9A are disposed so that the top plate 7a and the bottom plate 9a are parallel and the first side plate 7b and the second side plate 9b are parallel, thereby forming a connector insertion space S into which the connector is inserted.

As shown in FIG. 8, the cage 2B includes two top covers 7 and one bottom cover 9B.
　トップカバー７は、第１実施形態で説明したトップカバー７と同様である。ただし、図 ７に示すように、隣り合うトップカバー７同士を天板７ａの端部で接続する場合に、一方のトップカバー７の第３係合片１３ｃの孔部１３ｃ１に他方のトップカバー７の突起片１ ３ｅを挿入して固定する。トップカバー７の天板７ａの同図における右端とボトムカバー９Ｂの第２側板９ｂの上端との固定方法は第１実施形態と同様である。 The top cover 7 is the same as the top cover 7 described in the first embodiment. However, as shown in FIG. 7, when the adjacent top covers 7 are connected to each other at the end of the top plate 7 a, the other top cover 7 is inserted into the hole 13 c 1 of the third engagement piece 13 c of one top cover 7. Insert and fix the protruding pieces 1 3e. The fixing method of the right end of the top plate 7a of the top cover 7 in the figure and the upper end of the second side plate 9b of the bottom cover 9B is the same as in the first embodiment.
　図９には、ボトムカバー９Ｂを展開した状態が示されている。底板９ａの幅方向Ｄ２の寸法は、トップカバー７の幅方向Ｄ２の寸法の２倍となっている。背板９ｄの寸法も、底板９ａの幅方向Ｄ２の寸法に対応したものとなっている。底板９ａの幅方向Ｄ２における中央には、長手方向Ｄ１に沿って複数のスリット形状とされた差込孔部２２が形成されている。これら差込孔部２２には、トップカバー７のプレスフィット１７及び第５係合片１ ５ｂ（図２Ｂ参照）が差し込まれる。 FIG. 9 shows a state in which the bottom cover 9B is expanded. The dimension of the bottom plate 9a in the width direction D2 is twice the dimension of the top cover 7 in the width direction D2. The size of the back plate 9d also corresponds to the size of the bottom plate 9a in the width direction D2. At the center in the width direction D2 of the bottom plate 9a, a plurality of slit-shaped insertion holes 22 are formed along the longitudinal direction D1. The press-fit 17 of the top cover 7 and the fifth engagement piece 1 5b (see FIG. 2B) are inserted into these insertion hole portions 22.
　次に、図１０Ａ乃至図１０Ｆを用いてケージ２Ｂの組立方向について説明する。図１０Ａに示されているように、ボトムカバー９Ｂに対して、１つ目のトップカバー７を接続する。このときに、トップカバー７のプレスフィット１７及び第５係合片１５ｂが底板９ａに形成した各差込孔部２２に挿入されるように接続する。図１０Ｂに示すように、底板９ａから下方に向けて、プレスフィット１７及び第５係合片１５ｂが突出する。 Next, the assembly direction of the cage 2B will be described with reference to FIGS. 10A to 10F. As shown in FIG. 10A, the first top cover 7 is connected to the bottom cover 9B. At this time, the press fit 17 and the fifth engagement piece 15b of the top cover 7 are connected so as to be inserted into the respective insertion holes 22 formed in the bottom plate 9a. As shown in FIG. 10B, the press fit 17 and the fifth engagement piece 15b protrude downward from the bottom plate 9a.
　次に、図１０Ｃに示されているように、ボトムカバー９Ｂに対して、２つ目のトップカバー７を接続する。このときに、２つ目のトップカバー７の第３係合片１３ｃの孔部１３ ｃ１内に、１つ目のトップカバー７の突起片１３ｅが挿入されるように接続する。 Next, as shown in FIG. 10C, the second top cover 7 is connected to the bottom cover 9B. At this time, connection is made so that the protruding piece 13e of the first top cover 7 is inserted into the hole 13 c1 of the third engaging piece 13c of the second top cover 7.
　図１０Ｄに示されているように、１つのボトムカバー９Ｂに対して２つのトップカバー ７を接続した状態では、未だ突起片１３ｅ及び第１係合片１３ａが折り曲げられていない（突起片１３ｅについては拡大して示した図１０Ｅ参照）。そして、図１０Ｆに示すように、突起片１３ｅ、第１係合片１３ａ及び第３係合片１３ｃを折り曲げることによって確実に固定を行う。 As shown in FIG. 10D, in a state where two top cover rods 7 are connected to one bottom cover 9B, the protruding piece 13e and the first engaging piece 13a are not yet bent (about the protruding piece 13e). Is an enlarged view of FIG. 10E). Then, as shown in FIG. 10F, the protrusion 13e, the first engagement piece 13a, and the third engagement piece 13c are securely fixed by bending.

The dimension in the width direction D2 of the bottom plate 9a of the bottom cover 9B was set to twice the dimension in the width direction D2 of the top plate 7a of the top cover 7. Then, the two top covers 7 are connected in parallel in the width direction D2 with respect to one bottom cover 9B. Thereby, by using one bottom cover 9B and two top covers 7, two connector insertion spaces S can be formed in parallel.
　また、同様の形状とした２つのトップカバー７を用意することで、２つのコネクタ挿入空間Ｓを有する１×２のコネクタ装置とすることができるので、第１実施形態のような１×１のコネクタ装置のトップカバー７と共通化することができる。これにより、トップカバー７の金型をコネクタ数に応じて専用設計する必要がなくなり、コストを低減することができる。 In addition, by preparing two top covers 7 having the same shape, a 1 × 2 connector device having two connector insertion spaces S can be obtained, so that 1 × 1 as in the first embodiment. It can be shared with the top cover 7 of the connector device. Thereby, it is not necessary to design the die of the top cover 7 according to the number of connectors, and the cost can be reduced.
［変形例１］
　上記第２実施形態では、１×２のコネクタ装置としたが、並列に配置するコネクタ挿入空間Ｓの数は３つ以上でも良い。例えば、図１１及び図１２に示したように、４つのコネクタ挿入空間Ｓを有する１×４のケージ２Ｃとすることもできる。トップカバー７は、４つを幅方向Ｄ２に並列に設置する。ボトムカバー９Ｃの底板９ａの幅方向Ｄ２の寸法は、トップカバー７の幅方向の寸法の４倍となっている。本変形例についても、トップカバー ７を共通化することができ、コストを低減することができる。 [Modification 1]
In the second embodiment, the 1 × 2 connector device is used, but the number of connector insertion spaces S arranged in parallel may be three or more. For example, as shown in FIGS. 11 and 12, a 1 × 4 cage 2C having four connector insertion spaces S may be used. Four top covers 7 are installed in parallel in the width direction D2. The dimension in the width direction D2 of the bottom plate 9a of the bottom cover 9C is four times the dimension in the width direction of the top cover 7. Also in this modified example, the top cover 7 can be shared, and the cost can be reduced.

Each slide projecting piece 24 is formed with a slit-shaped slide hole 24a. The other top cover 7 to be connected is provided with a slide piece 25 to be inserted into the slide hole 24a at a position corresponding to the slide hole 24a. The slide piece 25 is erected with respect to the top plate 7a and has a base portion 25a and a tip portion 25 b. Both the base portion 25a and the distal end portion 25b extend in the longitudinal direction D1, and a predetermined interval T is formed in the longitudinal direction D1 between the base portion 25a and the distal end portion 25b. This interval T corresponds to the plate thickness t of the slide protruding piece 24 in which the slide hole 24a is formed. 14B, after the slide piece 25 is inserted into the slide hole 24a, the slide piece 25 is relatively slid in the longitudinal direction D1, and as shown in FIG. 14C, the base portion 25a and the distal end portion 25b of the slide piece 25 are slid.
