Description

  The present invention relates to a connector unit that can be used advantageously in places where a large number of solenoids such as an automatic transmission and a connector for supplying power to them are disposed, and in particular, the operation of an extra length of an electric wire by restricting the handling of the electric wire. This connector unit can prevent the electric wires from being damaged by biting in time, and the connector unit that improves the installation workability by simply making the connector housing in the same direction when attached to the wire harness. is there.

<Automatic transmission>
The automatic transmission controls one end side of the input shaft, one end side of the output shaft, a transmission gear mechanism that changes the rotation of the input shaft to a desired rotational speed and transmits it to the output shaft side, and controls the gear mechanism for transmission. Electronic components such as sensors required to perform this operation, wiring harnesses for signal transmission between the board and electronic components for holding a part of these electronic components, and signal transmission to the outside, and these components are housed inside The transmission gear mechanism includes a transmission case in which lubricating oil supplied to the transmission gear mechanism is stored below the internal space.
Since an automatic transmission has a large number of solenoids, a large number of connectors and electric wires for supplying power to the solenoids are required, and the electrical connection work for that is complicated. Therefore, heretofore, inventions that facilitate electrical connection work have been made (see, for example, Patent Document 1). However, the invention described in Patent Document 1 uses a wire pattern, and does not route a large number of electric wires.
Moreover, there exists a thing using a protector as what protects the electric wire pulled out from the connector outside and aims at the improvement of the path | route control of an electric wire (for example, refer patent document 2). However, since the invention described in Patent Document 2 is a large molded product, a space for mounting and a fixing mechanism thereof are required.
Moreover, since the routing route is fixed by a protector, the flexibility at the time of changing the mounting conditions is poor, and diversion is difficult.

<An example of a conventional mission case>
An example of a conventional transmission case is one in which a large number of wires are arranged without using a wire pattern and without using a protector for improving the wire path regulation. FIG. 8A is a plan view showing an example of the inside of a mission case in which a large number of wires are arranged. 8A, a plurality of (seven in FIG. 8) solenoids 50 are fixed to a base member 60 in a mission case 1000, and a mating connector (for example, a male connector) 40 is attached to the side surface of each solenoid 50. It is fixed. A connector (for example, female connector) 20 ′ is fitted to the counterpart connector 40. Two electric wires W are drawn out from the connectors 20 ′, respectively, and each electric wire W passes through the space between the connector 20 ′ and the side wall 1010 of the mission case 1000 toward the lead-out port 1020, and is led out therefrom.
Although not shown, the mission case 1000 is liquid-tightly covered with a separate cover. This internal space is filled with oil.

<Problem of conventional connector 20 '>
In this way, in the mission case 1000 of FIG. 8A, since the wires W drawn from the connector 20 ′ are led out toward the outlets 1020, the wires are randomly wired, and there is a single wire there. However, when it is sandwiched between the mission case 1000 and the cover, the liquid tightness is not maintained, and the filled oil may leak out. Therefore, in order to prevent the electric wire W from being sandwiched between the mission case 1000 and the cover, it is necessary to make a wide space between the connector 20 ′ and the side wall 1010 of the mission case 1000. It has become.
Further, as the vehicle vibrates, the electric wire W extending from the connector 20 ′ to the lead-out port 1020 also vibrates, thus directly affecting the terminals in the connector 20 ′.
Further, in order to prevent the electric wire W from being sandwiched between the mission case 1000 and the cover, it is necessary to separately bundle a bundle of disturbed electric wires with a binder at a predetermined interval, which increases the cost.
And since the electric wire W was pulled out directly from connector 20 ', when the pulling force generate | occur | produced in the electric wire W, it had a bad influence directly on the retention strength of the terminal in connector 20'.
In addition, since the outlet of the electric wire W of the connector 20 ′ is open directly, dust (contamination) of metal powder easily enters the connector 20 ′ from the opening, and short-circuits when the contamination enters the connector 20 ′. There was a danger.

<Connector unit 30 according to the prior invention of the present invention>
In order to eliminate all the disadvantages of the connector 20 ′ shown in FIG. 8A, the present applicant has first developed a connector unit 30 as shown in FIG. 8B.
8B, in the mission case 100, a plurality of (seven in FIG. 8) solenoids 50 are fixed to the base member 60, and a counterpart connector (for example, male connector) 40 is attached to the side surface of each solenoid 50. Is fixed. A connector (for example, a female connector) 20 is fitted to the counterpart connector 40, and the connector cover 10 is fitted to the connector 20. A connector unit 30 is formed by the connector cover 10 and the connector 20. Two electric wires W from each connector 20 are drawn out from each connector cover 10, and each electric wire W passes through all the connector covers 10 toward the outlet 120 and reaches the outlet 120. .
In this way, by using the connector unit 30 in which the connector cover 10 is attached to the connector 20 fitted to the mating connector 40, all the electric wires W can be passed through each connector cover 10, thereby The electric wires W are directed toward the outlet 120 in an orderly manner. Therefore, the space between the connector 20 and the side wall 110 of the mission case 100 can be narrowed, and the mission case 100 can be reduced in size.
Below, the connector 20 and the connector cover 10 which comprise the connector unit 30 are demonstrated.

<Connector 20 according to the Prior Invention of the Present Invention>
FIG. 9A is a perspective view before the connector and the connector cover according to the prior invention of the present invention are fitted together, and FIG. 9B is a perspective view after the connector and the connector cover are fitted together.
In FIG. 9A, the connector 20 according to the prior invention is formed by resin molding in a rectangular parallelepiped shape, and accommodates two terminals T (for example, female terminals which are not visible in FIG. 9) in the length direction. Terminal storage chambers 20T are provided on the left and right sides of the drawing, and a lance (not visible in FIG. 9) is provided on the bottom surface of each terminal storage chamber 20T. And the bending deformation | transformation space 20L of the lance is formed in the left and right of the figure under each terminal accommodating chamber 20T. A terminal (for example, a male terminal) of the mating connector 40 (see FIG. 8B) is inserted from the left side into the terminal accommodating chamber 20T that is visible on the left side in FIG. 9A and is electrically connected to the female terminal. Engagement protrusions 20K are formed on the upper outer side of the connector 20 so that the mating is not easily disengaged in a state where the mating with the mating connector 40 has been completed. It engages with the engaging recess (not visible in FIG. 8B).
The above description is the same as the conventional connector.
The feature of the prior invention is that the connector cover 10 according to the prior invention is fitted on the opposite side of the fitting side with the mating connector, and the fitting projection 20A that is tapered for that purpose is a rectangular parallelepiped. The connector 20 is formed at each of the four corners (only three are visible in FIG. 9A).
Therefore, the connector cover 10 according to the prior invention will be described below.

<Connector cover 10 according to the prior invention>
The connector cover 10 according to the prior invention of the present invention is formed by resin molding with the same material as the connector 20, and each has a flat plate-like ceiling portion 11, a bottom portion 12, and sides facing the ceiling portion 11 and the bottom portion 12, respectively. The wall portion 13 connecting the two has a U-shaped cross section.
Further, fitting spaces 10A in which fitting projections 20A formed at the four corners of the connector 20 are respectively locked are formed in the ceiling portion 11 and the bottom portion 12 in four places as follows.

<Fitting spaces 10A and 10A on the left and right of the ceiling portion 11>
The fitting space 10 </ b> A formed at the fitting direction end of the ceiling part 11 is symmetrical with the fitting space 10 </ b> A formed at the fitting direction end of the bottom part 12. A detailed description will be given of the fitting space 10A formed at the end in the mating direction.
The narrow portion 11N (N means narrow) continues from the fitting direction end of the ceiling portion 11 in the fitting direction (left side in FIG. 9), and the wide portion 11W (W is in the fitting direction of the narrow portion 11N). (Wide meaning) followed. And downward extension part 11D, 11D (D means a down) is each extended from the right-and-left both ends of the fitting direction edge part of the ceiling part 11 below.
Furthermore, downward extending portions 11WD and 11WD extend downward from the left and right ends of the wide portion 11W, respectively.
And the lowermost ends of each extending part 11D and each extending part 11WD are connected by connecting parts 11R and 11R (R is a meaning of Renket), respectively.
With the above configuration, the end of the ceiling part 11 in the fitting direction, the narrow part 11N, the wide part 11W, the downwardly extending part 11WD, the connecting part 11R, and the downwardly extending part 11D are connected and integrally enclosed, A fitting space 10A can be obtained inside.

<The fitting space 10A of the right and left of the bottom part 12>
Similarly, the bottom portion 12 also has a narrow width portion 12N that continues from the end in the fitting direction in the fitting direction (left side in FIG. 9), and a wide width portion 12W that continues in the fitting direction of the narrow width portion 12N. Further, upwardly extending portions 12U and 12U (U means up) extend from the left and right ends of the end portion of the bottom portion 12 in the fitting direction. Furthermore, upward extending portions 12WU and 12WU extend upward from the left and right ends of the wide width portion 12W, respectively. And the uppermost ends of each upper extension part 12U and each upper extension part 12WU are connected by connection parts 12R and 12R, respectively.
With the above configuration, the bottom portion 12 in the fitting direction end portion, the narrow width portion 12N, the wide width portion 12W, the upper extension portion 12WU, the connection portion 12R, and the upper extension portion 12U are connected and integrally surrounded by the shape. Thus, the fitting space 10A can be obtained.
Since the fitting spaces 10A are respectively formed on the left and right sides of the end portions in the fitting direction of the ceiling portion 11 and the bottom portion 12 of the connector cover 10, the fitting spaces 10A are formed in four corners on the top, bottom, left and right.
When the fitting protrusions 20A formed at the four corners of the connector 20 are locked from the inside into the fitting space 10A, the connector cover 10 is fitted to the connector 20 as shown in FIG. Thus, the connector unit 30 is completed.

<Advantages of connector unit 30 1: Simplification of wiring of electric wires>
Due to the presence of the connector cover 10, the connector unit 30 according to the prior invention simplifies the wiring of electric wires. FIG. 10A is a front view of the connector 20 as viewed from the connector cover 10 side, and FIG. 10B is a perspective view showing a housing procedure for housing the electric wire coming out of the connector 20 in the connector cover 10.
(1) In the connector 20 handled by the present invention, two female terminals and electric wires W1 and W2 crimped on the ends of the two female terminals are accommodated (see FIG. 10A). ), Two electric wires W1 and W2 are extended from the connector 20 to the connector cover 10 side (see FIGS. 10B and 1).
(2) Then, the connector cover 10 is brought close to the connector 20 (see FIGS. 10B and 2), and the electric wire W2 from the connector 20 is connected to the connecting portion 11R on the connector cover 10 and the lower connecting portion 12R. It pushes in from the gap (slit) formed between.
(3) Next, the remaining electric wire W1 from the connector 20 is also pushed into the inside through a gap formed between the upper connecting portion 11R and the lower connecting portion 12R of the connector cover 10 (FIG. 10 (B) (3 )reference).
By doing in this way, the two electric wires W1 and W2 from the connector 20 can easily enter the inside of the connector cover 10 from the front surface of the connector cover 10, and are further pulled out from the side through the inside. .
If there is no gap between the upper connecting portion 11R and the lower connecting portion 12R of the connector cover 10, the two electric wires W1 and W2 from the connector 20 are placed inside the connector cover 10. When passing the wire, the tips of the electric wires W1 and W2 are first inserted into the connector cover 10, and further, the tip is pulled out from the side through the inside, so such a task is considerably troublesome. .
However, according to this connector cover 10, it is only necessary to push the middle of the electric wires W1 and W2 coming out of the connector 20 into the inside from the gap (slit) between the connecting portion 11R and the connecting portion 12R of the connector cover 10. The property is significantly improved.
(4) Finally, when the connector cover 10 is brought close to the connector 20 and the fitting protrusions 20A at the four corners of the connector 20 are fitted into the fitting spaces 10A at the four corners of the connector cover 10, FIG. ), The connector cover 10 and the connector 20 are integrated, and the connector unit 30 is easily completed.
Thus, since it is only necessary to push the middle of the electric wire into the inside through the gap between the connecting portions of the connector cover, the workability is remarkably improved and the wiring of the electric wire is simplified.

<Advantage 2 of Connector Unit 30: Prevention of Twisting of Electric Wire>
Returning to FIG. 8B, the two electric wires W drawn from the rightmost connector 20 pass through the connector cover 10 of the adjacent connector unit 30 close to the outlet, and further to the connector cover of the adjacent connector unit 30. Go through 10 to the final outlet.
In addition, the two electric wires W drawn from the connector cover 10 of the connector unit 30 adjacent to the rightmost connector 20 also pass through the connector cover 10 of the adjacent connector unit 30 close to the outlet and further to the adjacent connector unit 30. Through the connector cover 10 and finally toward the outlet.
By doing so, all the wires W drawn from each connector unit 30 pass through the connector cover 10 up to the outlet, so that the outside of the connector unit as shown in FIG. There is no electric wire to be turned, and the wires are arranged in the same direction. Therefore, the electric wire is not twisted.

<Other advantages of the connector unit 30>
The connector unit 30 has the following five advantages in addition to the above 1 and 2.
3) Since the gap between the connector cover 10 and the mission case 100 can be narrowed as shown in FIG. 8B, it contributes to the reduction of the harness wiring space and the downsizing of the apparatus.
4) Since many electric wires are wired in the same direction, the conventional bundling operation of bundling the bundles of the electric wires W with a binder is not necessary, which can contribute to cost reduction.
5) Even if the vehicle vibrates, the electric wires W only vibrate between the connector covers 10, so that the vibrations are small and do not affect the terminals in the connector 20.
6) And since the electric wire W is pulled out through the connector cover 10 without being pulled out directly from the connector 20, even if a pulling force is generated in the electric wire W, the holding force of the terminals in the connector 20 is not directly affected.
7) Further, since the outlet of the electric wire W of the connector 20 is covered with the connector cover 10, the dust of the metal powder hardly enters the connector 20 and there is no risk of short-circuiting inside the connector 20.
When the connector cover 10 of the prior invention is used, the electric wires drawn from each connector 20 are directed to the lead-out port through the adjacent connector cover as shown in FIG. 8B, and the above advantages are obtained. .

<Improved points of connector unit 30>
However, as a result of subsequent studies, it has been found that the connector unit 30 according to the prior invention has three points to be improved. FIG. 4 is a perspective view showing a positional relationship between the connector unit according to the prior invention and a number of electric wires.
(1) As shown in FIG. 4, one of the positions of the connector covers is the electric wires W1 to W6 passing through the connector covers 10-1 to 10-3 of the three connector units 30-1 to 30-3. That is, the three connector units 30-1 to 30-3 have different directions depending on whether or not they pass. Therefore, it is necessary to adjust the orientation of the connector each time during the fitting operation, and a certain amount of time is required for the fitting operation.
(2) For example, in the case of the connector 20-3, it is difficult to specify which of the six electric wires W1 to W6 the electric wires W5 and W6 coming out of the connector 20-3 itself. .
(3) Further, for example, when the connector cover 10-3 rotates with respect to a vertical axis passing through the ceiling part 11 (FIG. 9A) and the bottom part 12 (FIG. 9A), the connector cover 10-3 It is difficult to return to the original.

  The present invention has been made in order to solve the above-described improvements, and shortens the time for fitting work by making all the connectors face the same direction as shown in FIG. 5 instead of FIG. At the same time, it is easy to identify which wire is coming out of each connector itself, and even if the connector cover rotates with respect to the vertical axis passing through its ceiling and bottom, it can return to its original state. The object is to provide a connector cover.

In order to achieve the above-described object, the connector units (1) to (3) according to the present invention are characterized by the following.
(1): In a connector unit composed of a connector and a connector cover that is fitted to the wire drawing side of the connector,
The connector cover has a hollow rectangular parallelepiped (including hollow cubes) lacking both sides,
A lower extending part extending downward from the tip of the hollow rectangular parallelepiped on the fitting side with the connector and an upper extending part extending upward from the tip of the hollow rectangular parallelepiped on the fitting side are respectively provided. A first fitting portion is provided on each of the ceiling portion and the bottom portion, and a second fitting portion is provided on the fitting side of the connector with the connector cover. ,
A routing rib is provided downward from the ceiling 11 of the hollow rectangular parallelepiped or upward from the bottom 12.
(2): In the above (1), an electric wire from the connector is passed through a wire direction regulating portion formed between the lower extension portion and the upper extension portion and the routing rib, and the routing rib and the connector Allow wires other than the connector to pass through the wire collecting portion formed between the wall portion of the cover.
(3): In the above (1) or (2), one of the electric wires from the connector is passed through the electric wire direction restricting portion, and the remainder of the electric wires from the connector bypasses the wiring rib and the electric wire collecting portion. Pass through.
(4): In any one of the above (1) to (3), a hinge is formed in the direction perpendicular to the fitting direction at the ceiling of the hollow rectangular parallelepiped or the bottom of the hollow rectangular parallelepiped, and the hinge is centered A space is formed between the tip of the routing rib and the hinge by rotating the fitting side of the ceiling or the bottom.

According to the present invention, when the connector cover according to the present invention is used, all connector units can be aligned in the same direction, so the direction of each connector unit is corrected when mated with the mating connector. This eliminates the need for time, and can greatly reduce the mating time between a large number of connectors.
Moreover, it becomes easy to identify which electric wire is coming out of each connector itself.
Furthermore, even if the connector cover rotates with respect to a vertical axis passing through the ceiling and bottom portions, the connector cover can be returned to its original state.
By forming the hinge on the connector cover according to the present invention, a space is formed between the tip of the routing rib and the hinge, so that it is easy to accommodate the wire bundle in the connector cover, and the time required for fitting Can be greatly shortened.

FIG. 10A is a front view of the connector 20 as viewed from the connector cover 10 side, and FIG. 10B is a perspective view showing a housing procedure for housing the electric wire coming out of the connector 20 in the connector cover 10.

  In the following, all connectors are oriented in the same direction, making it easy to identify which wires are coming out of the connectors themselves, and the connector cover rotates with respect to the axis passing through its ceiling and bottom. However, the connector cover according to the present invention that can return to the original state will be described in detail with reference to the drawings.

<Connector cover 10 according to the present invention>
1A is a perspective view of the connector cover according to the present invention, and FIG. 1B shows a state in which two wires drawn from the connector side are inserted through the connector cover of FIG. It is a top perspective view of a connector cover. Since the connector cover 10 according to the present invention is basically the same as the connector cover 10 according to the prior invention described with reference to FIG. 9A, the description of the overlapping reference numerals is omitted.
The connector cover 10 according to the present invention is different from the connector cover 10 according to the preceding invention of FIG. 9A in that the connector cover 10 according to the present invention is from the inside of the ceiling portion 11 of the connector cover 10 of FIG. The wiring ribs 14 having a predetermined length in the width direction are integrally resin-molded with the same material as the connector cover 10 toward the bottom 12 in the downward direction.

<Wiring rib 14 according to the present invention>
FIG. 2 is a five-side view of the connector cover 10 according to the present invention shown in FIG.
In FIG. 2, the middle drawing S is a front view, the upper drawing H is a plan view, the lower drawing T is a bottom view, the right drawing R is a side view seen from the right, and the left drawing L is seen from the left. It is a side view.
From the five views, it can be seen that the connector cover 10 according to the present invention is formed with the wiring ribs 14 extending from the inner side of the ceiling part 11 of the connector cover 10 to the vicinity of the bottom part 12 in the full width direction. Therefore, when two wires from the connector side are passed through the connector cover 10 (see FIG. 1B), the result is as shown in FIG.
3 is a six-sided view of the connector cover shown in FIG. 2 when the connector-side wires are wired. Drawing S is a front view, drawing H is a plan view, drawing T is a bottom view, and drawing R is viewed from the right. Side view, Drawing L is a side view seen from the left, Drawing A is AA arrow sectional drawing of Drawing R.

<Positional relationship between the two electric wires W1, W2 and the routing rib 14>
In FIG. 3, one of the two electric wires W1, W2 from the connector side of the connector cover 10 on its own side, W1 is a wire direction regulating portion 14A formed between the routing rib 14 and the extended portion 11D of the ceiling portion 11. In a state of clearance (see FIG. 3A).
The other electric wire W2 of the electric wires W1 and W2 passes through the electric wire direction restricting portion 14A to the opposite side to the electric wire W1 in a state of clearance, bypasses the wiring rib 14, and then between the wiring rib 14 and the wall portion 13 It passes in the same direction as the electric wire W1 through the electric wire aggregation part 14B in between (refer drawing 3 (A)).
And many electric wires W3-Wn which arrived from the other connector cover have passed the electric wire aggregation part 14B (refer drawing 3 (A)).

<Holding the horizontal state by the routing rib 14: Effect 1>
Thus, one (W1) of the two electric wires W1 and W2 passes through the front side (connector side) of the wiring rib 14 of the connector cover, and the other (W2) is the back side (wall 13 side) of the wiring rib 14. Since the two wires W1 and W2 are arranged in parallel at the same height across the wiring rib 14, the connector cover can maintain a horizontal state (see FIG. 5).
Since this is true for all connector covers, a connector unit having such a connector cover can also maintain a horizontal state.
Moreover, what is necessary is just to let the electric wire group from the other connector unit 30 which arrives at the connector unit 30 pass the electric wire aggregation part 14B horizontally.
As a result, all the connector units are maintained in the horizontal state as shown in FIG.

<All connector units remain in the same horizontal state>
FIG. 5 is a perspective view showing the positional relationship between the connector unit according to the present invention and a number of electric wires. As described above, since any connector unit 30-1 to 30-3 includes the connector covers 10-1 to 10-3 according to the present invention, any connector unit 30-1 to 30-3 maintains a horizontal state. doing.
Therefore, when each of the connector units 30-1 to 30-3 is fitted with the mating connector, the orientation of the connector units 30-1 to 30-3 is aligned, so that the fitting operation is progressed. It becomes like this.
Further, a part of the electric wires of the own connector unit 30 is horizontally passed through the electric wire direction restricting portion 14A, and the remaining portion of the electric wires of the own connector unit 30 and the electric wire group coming from the other connector unit 30 are connected to the electric wire collecting portion 14B. By passing the wires horizontally, all the wires are flat, which also prevents the connector from rotating further. When each connector unit is mated with the mating connector, the orientation of the connector unit As a result, the mating work progresses.

<Easy to identify the wire from the connector itself by the routing rib 14: Effect 2>
Since one of the wires coming out of its own connector is always routed through the wire direction restricting portion 14A side of the connector cover's routing rib 14, the wire passing through the wire direction restricting portion 14A It becomes easy to specify that the wire is from the connector with which the connector cover is fitted.

<Even if the connector cover rotates, the wiring rib 14 returns to the original state: Effect 3>
Of the two wires W1, W2, one wire W2 is routed from the front side (connector fitting side) to the back side (wall 13 side) of the routing rib 14 (FIG. 3A). See), the connector cover is difficult to rotate with respect to the axis passing through the ceiling and bottom, and even if it rotates, the electric wire entangled with the routing rib 14 tries to return to its original state. Because the force works, it becomes easy to return to the original state. Therefore, even if there is a rotation, the direction of the connector unit returns to the original position again, so that the fitting work is progressed.

<Other variations>
In the above description, the shape of the connector cover has been described as a rectangular parallelepiped. However, it is needless to say that the shape of the connector cover is not limited to a rectangular parallelepiped and may be a cube.
Moreover, although the wiring rib 14 was formed below from the ceiling part 11, as long as an electric wire is passed, you may form the wiring rib 14 toward the upper part from the bottom part 12. FIG.
Further, as can be seen from FIG. 3A, the routing ribs 14 are formed to have the same length as the length of the connector cover 10 in the width direction (direction perpendicular to the fitting direction) to provide a function of preventing rotation. However, since the electric wire protrudes from the width direction of the connector cover 10, if it is desired to avoid it, the wiring rib 14 ′ has a function of preventing rotation as shown in FIG. It is good to form so that an electric wire may not protrude from the width direction of the connector cover 10.

<Further Improvement of Connector Cover 10 According to the Present Invention>
FIG. 6 is a view showing a further improvement of the connector cover of FIG. 1, and is a perspective view of the connector cover in which a hinge is formed on the bottom 12. 6 (A) (1) shows a state in which the hinge is closed, FIGS. 6 (A) and (2) show a state in which the hinge is open, and FIG. 6 (B) shows a state in which the hinge in FIGS. 6 (A) and (2) is open. It is the figure which showed a mode that an electric wire was let to pass through the connector cover.
FIG. 7 is a five-side view of the connector cover with the hinges of FIGS. 6A and 6A closed. Drawing S is a front view, drawing H is a plan view, drawing T is a bottom view, and drawing R is a right view. The side view seen from the figure, Drawing L is the side view seen from the left.
As shown in FIGS. 6A and 6A, the hinge 12 </ b> H is formed in the vicinity of the wall portion 13 of the bottom portion 12 in the full direction (width direction) perpendicular to the fitting direction. On the other hand, the routing ribs 14 are formed downward from the inside of the ceiling portion 11 as described above. Therefore, when the fitting side of the bottom portion 12 is rotated around the hinge 12H, FIG. ), A large space is opened between the tip of the routing rib 14 and the hinge 12H.
Therefore, a large number of electric wires W3 to Wn from other connector units other than the connector unit are passed through the electric wire aggregation portion 14B formed between the wiring rib 14 of the connector unit and the wall portion 13 of the connector cover 10. In this case, the fitting of the closed bottom portion 12 (see FIG. 6A (1)) is removed, and the connector fitting side of the bottom portion 12 is lowered with the hinge 12H as the center as shown in FIG. 6A (2). When rotated, a large space is opened between the routing rib 14 and the hinge 12H. Therefore, it is only necessary to push the middle portions of the numerous electric wires W3 to Wn from here and arrange them horizontally as shown in FIG.
Thereafter, the fitting side of the bottom portion 12 is closed, and the left and right fitting protrusions 20A formed at the corresponding portions of the connector 20 are locked in the fitting spaces 10A on the left and right sides of the bottom portion 12 of the connector cover 10, respectively. A large number of wires W3 to Wn from other connector units can be passed through the wire collecting portion 14B of the connector cover 10 of the connector unit 30 in a horizontal state.

<Summary>
By forming the hinge on the bottom, turning the mating side of the bottom about the hinge opens a large space between the routing rib and the hinge, so many wires from other connector units can be connected to the connector cover. Can be easily integrated into the electric wire aggregation section.
On the other hand, in the case of the connector cover as shown in FIG. 1 without such a hinge 12H, a large number of electric wires W3 to Wn from other connector units have their tips at the electric wire collecting portion 14B of the connector cover 10 of the connector unit 30. This work was laborious and cumbersome.
