[0011] <Embodiment>

[0012] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0013] 1 is a perspective view of a connector unit 1 according to an embodiment. The connector unit 1 includes a plurality of connector portions 10, a fitting portion 20 to which the plurality of connector portions 10 are attached, and a cover portion 30 that holds the plurality of connector portions 10 in the fitting portion 20. The connector unit 1 is a unit for connecting the general-purpose connector portion 10 connectable to various devices to a specific dedicated device via the fitting portion 20 for the dedicated device.

[0014] As shown in the figure, the orientation of the connector unit 1 can be specified by the coordinates of the left-right direction, the front-back direction, and the up-down direction. The left-right direction is the direction in which the multiple connector parts 10 are lined up, and is also the width direction of the mating part 20. The front-back direction is a direction perpendicular to the left-right direction and is the longitudinal direction of the connector parts 10. The up-down direction is a direction perpendicular to the left-right direction and the front-back direction and is the height direction of the connector unit 1.

[0015] Fig. 2 is an exploded perspective view of the connector unit 1 shown in Fig. 1. In this embodiment, five connector parts 10 are attached to through holes 22 provided in the fitting part 20. The five connector parts 10 include three different types of connector parts 10A, 10B, and 10C. The cover part 30 holds the five connector parts 10 together in the fitting part 20 from above in the vertical direction. The cover part 30 is fixed to the fitting part 20 by bolts 32.

[0016] Fig. 3 is a perspective view of the connector portion 10. Fig. 3 shows the connector portion 10A among the three different types of connector portions 10A, 10B, and 10C shown in Fig. 2.

[0017] The connector portion 10A has a terminal-attached electric wire 12 extending in the front-rear direction, a housing 14 that accommodates a terminal (not shown) provided at one end of the terminal-attached electric wire 12 therein and has an opening 15 capable of receiving a mating terminal, and a holding plate 16 that extends outwardly from the housing 14 in a flange-like shape. The housing 14 and the holding plate 16 are formed of, for example, resin. The connector portions 10B and 10C have a different overall shape from the connector portion 10A, but have members corresponding to the terminal-attached electric wire 12, the housing 14, and the holding plate 16, respectively.

[0018] Furthermore, the connector portion 10A has a temporary-locking projection 17 that functions as a temporary-locking portion that locks the housing 14 to the fitting portion 20 when the opening 15 of the housing 14 is inserted into the through hole 22 of the fitting portion 20. The housing 14, the holding plate 16, and the temporary-locking projection 17 are integrally molded from, for example, resin. The role of the temporary-locking projection 17 will be described later (FIG. 6).

[0019] 4 is a perspective view of the cover portion 30. The cover portion 30 is a member extending in the left-right direction so as to correspond to the five connector portions 10, and is formed of, for example, resin. It has a plurality of partition wall portions 33 extending in the front-rear direction, and a plurality of plate-shaped connector holding portions 34 formed between adjacent partition wall portions 33. The cover portion 30 further has a bolt through hole 36 through which a metal bolt 32 passes. The cover portion 30 will be described in detail later.

[0020] Fig. 5 is a top view of an assembly in which the connector portion 10 is mounted to the fitting portion 20. Fig. 6 is a rear view of Fig. 5. The fitting portion 20 is formed, for example, from resin, and has a plurality of through holes 22 that penetrate in the vertical direction. An operator can provisionally lock the multiple connector portions 10 to the fitting portion 20 by inserting the housing 14 and openings 15 of each of the multiple connector portions 10 into the corresponding multiple through holes 22 from above. The openings 15 can receive mating terminals from below in Fig. 6.

[0021] The temporary-locking projections 17 provided in the opening 15 are made of the same resin as the housing 14. Therefore, when the housing 14 is inserted into the through-hole 22, the temporary-locking projections 17 are pressed inward and deformed. Then, as shown in Fig. 6, when the insertion is completed, the temporary-locking projections 17 are caught on the edge of the through-hole 22 and can function as a temporary-locking portion that temporarily locks the housing 14 to the fitting portion 20. Here, the cover portion 30 is not attached.

[0022] Fig. 7 is a top view of the connector unit 1, and Fig. 8 is a cross-sectional view taken along line AA in Fig. 7. Figs. 7 and 8 also show a state in which a cover portion 30 is attached to the assembly of Figs. 5 and 6.

[0023] The worker can then position the cover portion 30 from above while aligning the assembly of Figures 5 and 6 so that each of the multiple partition wall portions 33 of the cover portion 30 matches both side surfaces of each connector portion 10, and assemble the cover portion 30 to the mating portion 20 by passing the bolts 32 through the bolt through holes 36 and fastening them to the bolt holes 24 (see Figure 5) of the mating portion 20.

[0024] As shown in FIG. 5, when the connectors 10 are inserted into the through holes 22 of the housing 14, the retaining plates 16 of the connectors 10 are disposed at the peripheral portions 26 (see FIG. 2, in front of the through holes 22 in the embodiment) that are located near the through holes 22. Therefore, as shown in FIG. 8, when the operator fixes the cover 30 to the fitting portion 20, the retaining plates 16 are sandwiched between the peripheral portions 26 of the through holes 22 and the connector retaining portions 34 of the cover 30. As a result, the five connectors 10 are collectively attached to the fitting portion 20. Although the cross section of the retaining plate 16 of the connector 10C is not shown in FIG. 8, the retaining plate 16 of the connector 10C is also sandwiched between the connector retaining portions 34 of the cover 30 and the corresponding peripheral portions 26, as in the other connectors 10A and 10B.

[0025] This allows the multiple connector parts 10 to be attached to the fitting part 20 together in a state where the cover part 30 and the fitting part 20 sandwich the respective holding plates 16 of the multiple connector parts 10 together. Therefore, even if the number of connector parts 10 increases, the number of bolts 32 does not increase, so that the work of fixing the connector parts 10 does not require a long time and an increase in costs can be suppressed. In addition, a large amount of space is not required to fasten the bolts 32, so that the connector unit 1 can be prevented from becoming large in size.

[0026] 6, at least connector part 10A of the five connector parts 10 has temporary-locking projections 17 that lock housing 14 to fitting part 20 when opening 15 of housing 14 is inserted into through hole 22. Therefore, temporary-locking projections 17 lock housing 14 to fitting part 20, preventing connector part 10 from falling off fitting part 20 when opening 15 is inserted into through hole 22, and preventing a decrease in work efficiency. Note that connector parts 10B and 10C do not have temporary-locking projections 17, but temporary-locking projections 17 may be provided in connector parts 10B and 10C.
