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 connectors for supplying power to the same are disposed, and in particular, a batch unit that can greatly reduce the fitting time of the connector unit. The present invention relates to a fitting device.

<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.

<An example of a conventional mission case>
FIG. 6A is a plan view showing an example of the inside of a conventional mission case in which a large number of wires are arranged. 6A, a plurality of (seven in FIG. 6) solenoids 50 are fixed to a base member 60 in a mission case 1000, and a mating connector (for example, male connector) 40 is attached to the side 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. Each electric wire W passes through the space between the connector 20 ′ and the side wall 1010 of the mission case 1000 toward the outlet 1020 and is led out from there.
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. 6A, the electric wires W drawn from the connector 20 ′ are led out toward the outlets 1020, so that the electric wires are randomly wired, and there is a single electric 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>
Therefore, in order to eliminate the drawbacks of the connector 20 ′ shown in FIG. 6A, the present applicant has first developed a connector unit 30 as shown in FIG. 6B.
6B, in the mission case 100, a plurality (seven in FIG. 6) of 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 the respective connectors 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. 7A is a perspective view before the connector and the connector cover are fitted according to the prior invention of the present invention, and FIG. 7B is a perspective view after the connector and the connector cover are fitted.
7A, the connector 20 according to the prior invention is formed by resin molding in a rectangular parallelepiped shape, and has a terminal accommodating chamber 20T for accommodating two terminals T (not visible in FIG. 7) in the length direction therein. In the right and left of the figure, a lance (not visible in FIG. 7) is provided on the bottom surface of each terminal accommodating 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. The terminals of the mating connector 40 (see FIG. 6B) are inserted from the left side into the terminal accommodating chamber 20T visible on the left side in FIG. 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. 6B).
The above description is the same as the conventional connector.
The feature of the prior invention of the present invention is that, in such a connector 20, fitting protrusions 20A for fitting the connector cover 10 according to the prior invention are provided at four corners (FIG. 7) on the opposite side of the fitting side with the mating connector. In (A), only three are visible.).

<Connector Cover 10 According to Prior Invention of the Present 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 continues in the fitting direction (left side in FIG. 7) from the fitting direction end of the ceiling portion 11, and the wide portion 11W continues in the fitting direction of the narrow portion 11N. And downward extension part 11D, 11D is each extended from the right-and-left both ends of the fitting direction edge part of the ceiling part 11 downward. 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, 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 integrally enclosed with the inside. A joint space 10A is obtained.

<The fitting space 10A on the right and left of the bottom 12>
Similarly, the bottom portion 12 also has a narrow width portion 12N that continues from the end portion in the fitting direction in the fitting direction (left side in FIG. 7), and a wide width portion 12W that continues in the fitting direction of the narrow width portion 12N. Further, upper extending portions 12U and 12U extend upward from both 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-described configuration, the bottom portion 12 is fitted inward by a shape that is integrally surrounded by the fitting direction end portion, the narrow width portion 12N, the wide width portion 12W, the upper extension portion 12WU, the connecting portion 12R, and the upper extension portion 12U. A space 10A is 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, the fitting spaces 10A are formed at the four corners in all directions.
When the fitting projections 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>
The advantage of the connector unit 30 according to the prior invention is that the presence of the connector cover 10 simplifies the wiring of electric wires. FIG. 8A is a front view of the connector 20 as viewed from the connector cover 10 side, and FIG. 8B 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, as shown in FIG. 8A, two electric wires W1 and W2 are accommodated by being electrically connected to the end portions of the metal terminals. Two electric wires W1 and W2 are extended to the side (see FIGS. 8B and 1).
(2) Then, the connector cover 10 is brought close to the connector 20, and the electric wire W2 from the connector 20 is passed through a gap (slit) formed between the upper connecting portion 11R and the lower connecting portion 12R of the connector cover 10. It pushes in (refer FIG. 8 (B) (2)).
(3) Next, the remaining electric wire W1 from the connector 20 is also pushed into the interior from the gap formed between the upper connecting portion 11R and the lower connecting portion 12R of the connector cover 10 (FIG. 8B (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 further easily pass out from the side through the inside. It becomes like. If there is no gap formed between the upper connecting portion 11R and the lower connecting portion 12R of the connector cover 10, the ends of the two electric wires W1 and W2 from the connector 20 are closed. Since this is an operation for putting the connector cover 10 into the connector cover 10 and then pulling the tip outward from the side surface through the interior, such an operation is quite troublesome.
(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.

<Advantages of connector unit 30: prevention of twisting of electric wires>
FIG. 9 shows a perspective view of four connector units 30 in which a large number of electric wires drawn out from the respective connectors 20 are arranged in an orderly manner toward the outlets. The two electric wires W1 and W2 drawn from the connector cover 10-1 of the connector unit 30-1 pass through the connector cover 10-2 of the adjacent connector unit 30-2, and further, the adjacent connector unit 30- 3 passes through the connector cover 10-4 of the connector unit 30-4 and the connector cover 10-3.
The two electric wires W3 and W4 drawn from the connector cover 10-2 of the adjacent connector unit 30-2 are connected to the connector cover 10-3 of the adjacent connector unit 30-3 and further to the adjacent connector unit 30-4. Through the connector cover 10-4 toward the outlet.
Similarly, the two electric wires W5 and W6 drawn out from the connector unit 30-3 also pass through the connector cover 10-4 of the adjacent connector unit 30-4 and go to the outlet.
The two electric wires W7 and W8 drawn out from the connector unit 30-4 are also drawn out from the connector cover 10-4 toward the outlet.
In this way, all the electric wires W drawn from each connector unit 30 pass through all the connector covers 10 adjacent to and after that, many electric wires are wired in the same direction, and are twisted (twisted). There is no electric wire. In the conventional wiring state of the electric wire W as shown in FIG. 6A, the electric wire is twisted. Therefore, the direction of the force applied to each connector 20 ′ is different, so that the direction of each connector 20 ′ becomes different. When mating with the mating connector, it was necessary to prepare the orientation. However, in the connector unit 30, since many wires are oriented in the same direction, each connector 20 is oriented in the same direction. When mating with the connector, the work of adjusting the orientation is omitted.

<Other advantages of the connector unit 30>
The operation of bundling the bundle of electric wires W with a conventional binder is not necessary, which can contribute to cost reduction.
Further, since the gap between the connector cover 10 and the mission case 100 may be narrow, it can contribute to miniaturization.
Even if the vehicle vibrates, each electric wire W only vibrates between the connector covers 10, so that the vibrations are small and do not affect the terminals in the connector 20.
And since the electric wire W is pulled out via the connector cover 10 without being pulled out directly from the connector 20, even if the tensile force arises in the electric wire W, the holding force of the terminal in the connector 20 is not directly affected.
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.

<Problem of connector unit 30>
In FIG. 6B, in order to fit the connector 20 on the connector unit 30 side to each counterpart connector 40 attached to the side surface of the seven solenoids 50, the connectors 20 are fitted to the counterpart connector 40 one by one. There was a need to go. Therefore, a great amount of time is required to finish fitting the connector 20 to the mating connector 40 of the seven solenoids 50. ,
