Description

  The present invention relates to a connector unit and a wiring structure including the connector unit.

  Conventionally, electric wires for transmitting electric power from a battery and a control signal from a control device to an electronic device are routed in the vehicle. When routing these wires, it is necessary to properly regulate the routing route and protect the wires. For example, Patent Documents 1 and 2 disclose a connector including a cover for realizing protection and path regulation of an electric wire drawn out from the connector to the outside.

  Patent Document 3 discloses an example in which an electric wire is routed inside a transmission to perform signal transmission between electronic components and signal transmission with the outside. This type of conventional transmission is necessary for controlling the transmission gear mechanism in the transmission case and changing the rotation of the input shaft to the desired rotational speed and transmitting it to the output shaft side. Electronic components such as various sensors and solenoids, a substrate for holding these electronic components, and electric wires for signal transmission between the electronic components and signal transmission with the outside.

  FIG. 9 is a plan view schematically showing an example of a wiring form of a wire inside a conventional mission case. In the example shown in FIG. 9, a base member 160 for fixing electronic components and the like in a rectangular mission case 170 and a plurality of (seven in the example of FIG. 9) fixed to the base member 160. The solenoid 150, a mating connector 140 (for example, a male connector) fixed to each side of the solenoid 150, a connector 120 (for example, a female connector) that fits the mating connector 140, and the connector 120 are led out and guided. An electric wire 180 extended to the outlet 171 and led out to the outside from the outlet 171 is accommodated. The electric wire 180 includes a branch line 181 drawn out from the connector 120 and a trunk line 182 in which the branch lines 181 are bundled. The mission case 170 is liquid-tightly covered with a separate cover (not shown). Then, oil is filled in the internal space surrounded by the mission case 170 and the cover.

  In such a conventional wiring form, as shown in FIG. 9, since the electric wires 180 led out from the connector 120 are led out toward the outlets 171, respectively, it is difficult to regulate the wiring route of the electric wires 180. It was. For this reason, as shown by the code | symbol 185 in FIG. In this case, there is a possibility that the electric wire 180 is sandwiched between the mission case 170 and the cover during the sealing operation, and the liquid tightness inside the mission case 170 cannot be maintained.

  In order to prevent such pinching, it is conceivable to use a connector as shown in Patent Documents 1 and 2, but since the connector is a large molded product, a relatively wide mounting space is required. The case 170 becomes large. In this case, the transmission case 170 is enlarged because a fixing mechanism for attaching the connector is required. Furthermore, when the connector is used, the routing route is fixed, so that the flexibility in changing the design is poor and it is difficult to divert the parts.

  Further, although it is conceivable to bundle the main line 182 portion of the electric wire 180 with a binder (not shown), it is difficult to attach the electric wire 180 so that the routing route of the electric wire 180 is appropriately regulated, and the cost is high. Moreover, in order to prevent pinching, it is possible to make wide the space between the connector 120 and the side surface of the mission case 170, but the mission case 170 will be enlarged. Moreover, in the conventional wiring form, since the electric wire 180 is directly pulled out from the connector 120, when a tensile force acts on the electric wire 180, a force is easy to act on the terminal accommodated in the connector 120, and a connection failure etc. are caused. there is a possibility. Furthermore, in the conventional wiring form, since the drawing surface side of the branch line 181 of the connector 120 is opened, there is a possibility that fine metal fragments (contamination) may enter the connector 120 from the opening, causing a short circuit. There was a possibility.

  On the other hand, the present applicant devised a connector unit as shown in FIGS. 10 and 11 as a prior invention of the present invention. FIG. 10 is a plan view showing an example of the wiring form of the electric wire in the mission case when the connector unit according to the prior invention is used, and FIG. 11 is the electric wire when the connector unit according to the prior invention is used. It is a perspective view which shows the arrangement | positioning form. The connector unit according to the prior invention is common to an insertion type connector unit 30C (see FIGS. 1 and 7) of an embodiment described later. Further, the connector unit (insertion type connector unit 30C) according to the preceding invention is common to the connector units (first binding type connector unit 30A and second binding type connector unit 30B described later) according to the embodiment as will be described later. The connector 20 is provided.

  The insertion-type connector unit 30C is formed in a bottomed cylindrical shape having a connector 20 from which a branch line 81 branched from a trunk line 82 is drawn, and a bottom surface and a side surface, and is assembled to a drawing surface side of the branch line 81 of the connector 20 10C, and is accommodated in the mission case 70. The connector 20 accommodates a terminal (for example, a female terminal, not shown) that is electrically connected to the tip of the branch wire 81, and fits with the mating connector 40 fixed to the side surface of the solenoid 50. The mating connector 40 contains a plurality of mating terminals (for example, male terminals, not shown) that are electrically connected to the terminals. When the connector 20 and the mating connector 40 are fitted together, both ends thereof are accommodated. The child is electrically connected.

  A wire insertion port 16 is formed on the opposing side surface of the connector cover 10, and as shown in FIG. 11, a trunk line 82 is inserted into the wire insertion port 16 and a branch line 81 is drawn from the wire insertion port 16. As shown in FIG. 11, the trunk line 82 from the adjacent insertion-type connector unit 30C is inserted into the wire insertion port 16 and passes through the connector cover 10C, and the trunk line 82 and the drawn branch line 81 merge. The main line 82 is routed to the next insertion type connector unit 30C side. That is, the connector cover 10 </ b> C is an insertion type connector cover in which the branch line 81 and the trunk line 82 are inserted into the wire insertion port 16. Thus, in the insertion type connector unit 30C, the wiring direction of the branch line 81 and the trunk line 82 is guided by the connector cover 10C. Thus, according to the insertion type connector unit 30C, the routing direction can be regulated by appropriately guiding the routing direction of the branch line 81 and the trunk line 82 by the connector cover 10C.

  According to the routing form shown in FIG. 10 using such a prior invention, the wires can be concentrated and routed by the connector cover 10C, so that space saving can be realized. Moreover, since the connector 20 can be directed in the same direction at the time of a fitting operation with the mating connector 40 by the connector cover 10C, the fitting operation becomes easy. Moreover, although the details will be described later, since the drawing direction of the electric wire 80 can be changed in accordance with the change of the routing route, the flexibility with respect to the design change is improved.

  Moreover, according to the routing form shown in FIG. 10 using the prior invention, the routing route can be regulated by the connector cover 10C, so that the binding by the binder can be omitted. Further, the mission case 70 can be reduced in size. Moreover, since the electric wire 80 is pulled out via the connector cover 10 </ b> C, even if a tensile force acts on the electric wire 80, the force hardly acts on the terminals accommodated in the connector 20. Further, since the lead-out surface side of the connector 20 is covered with the connector cover 10C, it is difficult for contaminants to enter from the opening.

  Thus, according to the routing form using the insertion type connector unit 30C according to the prior invention, the problems of the prior art can be solved. However, in the insertion-type connector unit 30C according to the prior invention, the connector cover 10C is an insertion-type connector cover in which the branch line 81 and the trunk line 82 are inserted into the electric wire insertion port 16, and is configured to be rotatable with respect to the trunk line 82. ing. For this reason, the entire insertion-type connector unit 30C rotates with respect to the main line, and the orientation of the plurality of connectors 20 may not be aligned (see FIG. 8A described later). Thereby, there was a possibility that the workability of attachment to the counterpart connector 40 may not be good.

  This invention is made | formed in view of the situation mentioned above, The objective is to provide the connector unit and wiring structure which can improve attachment workability | operativity.

In order to achieve the above-described object, the connector unit and the wiring structure according to the present invention are characterized by the following points.
(1) a connector that accommodates a terminal electrically connected to the tip of a branch line branched from the trunk line;
A connector cover that is formed in a bottomed cylindrical shape having a bottom surface and a side surface and is assembled from the opening side to the drawing surface side of the branch wire of the connector, and a connector cover in which a branch wire outlet is formed on the side surface
A wiring direction of the branch line and the trunk line by the connector cover such that the branch line is drawn out from the branch line outlet and the trunk line extends along the bottom surface outside the bottom surface Is a connector unit that is guided,
The connector cover has a bands insertion hole,
A band portion of a binding band that is attached to the connector cover and binds the trunk line is inserted into the band insertion hole.

  According to the connector unit (1), the trunk line is bound to the connector cover by the binding band, and the connector unit and the trunk line are firmly fixed. That is, the connector unit according to the above-described prior invention is an insertion-type connector unit, and the connector cover is an insertion-type connector cover, whereas the connector unit (1) is a bundling-type connector unit, and its connector The cover is a bundling connector cover that firmly binds the trunk line. For this reason, it can prevent that the whole connector unit rotates with respect to a trunk line, and can improve the attachment workability | operativity at the time of attaching a connector with respect to the other party connector.

  In the connector unit (1), any type of binding band can be attached to the connector cover as long as it has a band part that can be inserted into the band insertion hole. For example, it is assumed that a plurality of types of binding bands having different band lengths are prepared, and a type of binding band suitable for the number of trunk lines to be bound (that is, the thickness of the trunk line) is selected and used. . By using a binding band suitable for the number of wires, the wires can be bound without any gaps regardless of the number of wires. Alternatively, it is assumed that a plurality of types of binding bands formed of synthetic resins having different heat resistance characteristics are prepared, and the types of binding bands suitable for the use environment are selected and used. For example, when the connector unit is used in a mission case, depending on the specifications of the mission case, heat resistance to a relatively high temperature range of about 150 ° C. to 160 ° C. may be required. In some cases, heat resistance for only a relatively low temperature range of about ° C to 90 ° C may be sufficient. In such a case, it is conceivable to use a binding band having high heat resistance that can cope with any use environment, but using a synthetic resin with good heat resistance increases the cost. On the other hand, if high heat resistance is not required, cost can be reduced if a binding band that can be used only in a low temperature range is selected and used.

  Further, in the connector unit (1) above, when the binding is not necessary, the binding band can be removed and used. Therefore, whether or not the binding band is attached can be changed according to the application.

(2) The connector unit of (1) above,
The connector cover has an extending portion extending from the side surface or the bottom surface, and the band insertion hole is formed in the extending portion.

  In the connector unit of the above (2), since the band insertion hole is provided in the extending part extending from the side surface or the bottom surface, for example, compared with the case where the band insertion hole is provided in the side surface or the bottom surface itself. In addition, it is easy to insert the band part of the binding band, and molding is also easy.

(3) The connector unit of (1) or (2) above,
The connector cover has a plurality of band insertion holes in which the binding bands are inserted in different directions.

  According to the connector unit of (3) above, the binding band can be attached to the connector cover in different insertion directions, so that the binding direction can be changed in accordance with the arrangement direction of the trunk lines to be bound. For this reason, it is possible to surely bind the trunk lines and regulate the route regardless of the arrangement direction of the trunk lines to be bundled.

(4) a connector for accommodating a terminal electrically connected to the tip of a branch line branched from the trunk line;
A connector cover that is formed in a bottomed cylindrical shape having a bottom surface and a side surface and is assembled from the opening side to the drawing surface side of the branch line of the connector, and a connector cover in which a branch line drawing outlet is formed on the side surface ;
A wiring direction of the branch line and the trunk line by the connector cover such that the branch line is drawn out from the branch line outlet and the trunk line extends along the bottom surface outside the bottom surface Is a connector unit that is guided,
The connector cover has a pre-Symbol bottom or the binding band portion integrally formed on the side surfaces,
The trunk line is bound by the binding band part.

According to the connector unit of (4) above, the connector cover and the trunk line are bound by the binding band portion, and the connector unit and the trunk line are firmly fixed. That is, the connector unit according to the above-described prior invention is an insertion-type connector unit, and the connector cover is an insertion-type connector cover, whereas the connector unit (4) is a bundling-type connector unit, and its connector The cover is a bundled connector cover. For this reason, it can prevent that the whole connector unit rotates with respect to a trunk line, and can improve the attachment workability | operativity at the time of attaching a connector with respect to the other party connector.
Further, according to the connector unit (4), the binding band portion is formed integrally with the connector cover, so that the binding work can be easily performed as compared with the case where a separate binding band is attached.

(5) A bundling type connector unit that is any one of the above (1) to (4), and an insertion type connector unit, and guides the trunk line and the branch line through a predetermined routing route. A routing structure,
The insertion-type connector unit includes the connector common to the bundling-type connector unit, and an insertion-type connector cover that is formed in a bottomed cylindrical shape having a bottom surface and a side surface and is assembled to the pull-out surface side of the connector. The wire insertion port is formed in the opposing side surface of the insertion type connector cover, the trunk line is inserted into the wire insertion port, and the branch line is drawn out from the wire insertion port.

As described above, in the insertion-type connector unit 30C according to the prior invention, the entire insertion-type connector unit 30C may be rotated with respect to the main line. On the other hand, rotation of the connector unit with respect to the main line can be prevented by using the bundled connector unit which is any one of the connector units (1) to (4).
Here, as shown in FIG. 9 and FIG. 10, when the routing route of the electric wires (main line and branch line) is regulated using a plurality of connector units, the rotation with respect to the main line is not necessarily prevented in all the connector units. There is no need. Therefore, as a configuration including both the bundling connector unit and the insertion type connector unit as in the wiring structure of the above (5), the bundling type connector unit is disposed at a location where rotation is to be prevented, and the other locations. It can be set as the structure which arrange | positions an insertion-type connector unit. With such a configuration, it is possible to reduce the number of bundling connector units that require a bundling operation of bundling bands and are expensive in product cost.
In particular, when the connector units (1) to (3) are used as a binding type connector unit, a relatively large number of trunk lines can be bound by changing the type of binding band to be attached as described above. Therefore, as a configuration including both the bundling connector unit and the insertion type connector unit as in the wiring structure of (5) above, the bundling type connector unit is arranged at a place where a relatively large number of trunk lines are wired, It can be set as the structure which arrange | positions an insertion-type connector unit in a location other than that.

  ADVANTAGE OF THE INVENTION According to this invention, the connector unit which can improve attachment workability | operativity can be provided.

  The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading through a mode for carrying out the invention described below (hereinafter referred to as an embodiment) with reference to the accompanying drawings.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a plan view showing an example of a wiring form of an electric wire in a mission case when the wiring structure according to the embodiment is used. In this embodiment, as shown in FIG. 1, a base member 60 for fixing an electronic component or the like in a rectangular mission case 70 and a plurality of (in this embodiment, 7.) From the solenoid 50, a mating connector 40 (for example, a male connector) fixed to the side surface of each solenoid 50, a connector 20 (for example, a female connector) that fits the mating connector 40, and the connector 20 An electric wire 80 that is drawn out and extends to the outlet 71 and is led out to the outside from the outlet 71 is accommodated. The electric wire 80 includes a branch line 81 drawn from each connector 20 and a trunk line 82 in which the branch lines 81 are bundled (FIGS. 3A and 3B, FIG. 6 and FIG. 11). The branch line 81 and the trunk line 82 are arranged in the first binding type connector unit 30A including the connector 20 and the connector cover 10A, the second binding type connector unit 30B including the connector 20 and the connector cover 10B, and the connector 20. It is guided by an insertion-type connector unit 30C having a connector cover 10C. The mission case 70 is liquid-tightly covered by a separate cover (not shown). Then, oil is filled in the internal space surrounded by the mission case 70 and the cover.
The insertion type connector unit 30C is the connector unit according to the above-described prior invention shown in FIGS. The first binding type connector unit 30A and the second binding type connector unit 30B have a common connector 20, and the connector 20 is also common to the connector 20 of the insertion type connector unit 30C.

  First, the first binding type connector unit 30A will be described. 2 is an exploded perspective view showing the first binding type connector unit and the male housing, FIG. 3 is a perspective view showing the first binding type connector unit in a state in which the trunk lines are bound, and FIG. 4 is a connector from the state of FIG. It is a perspective view which shows the state which rotated the cover by 90 degrees and was attached to the male housing.

  As shown in FIG. 2, the first bundling connector unit 30 </ b> A includes a connector 20 from which the branch line 81 is pulled out, and a connector cover 10 </ b> A that is assembled to the pulling surface 25 side of the branch line 81 of the connector 20. All of these members are formed of a synthetic resin.

  The connector 20 (for example, a female connector) includes a box-shaped housing 21 having a terminal housing chamber 22 formed therein, and a plurality of terminals (for example, female terminals) that are electrically connected to the distal ends of the branch lines 81. (Not shown) is accommodated in the terminal accommodating chamber 22. The connector 20 has a locking projection 23 that is locked to a locking portion 41 of a counterpart connector 40 (for example, a male connector) on the outer surface of the housing 21, and is fitted to the counterpart connector 40. The mating connector 40 contains a plurality of mating terminals (for example, male terminals, not shown) that are electrically connected to the terminals. When the connector 20 and the mating connector 40 are fitted together, both ends thereof are accommodated. The child is electrically connected.

  Further, on the outer surface of the housing 21 on the side of the lead-out surface 25, four locking protrusions 24 that are locked in locking holes 15 of the connector cover 10A described later are formed. The locking protrusions 24 are formed in the same shape at each of the four corners on the drawing surface 25 side. These four locking projections 24 can be locked in any of the four locking holes 15 of the connector cover 10 </ b> A, whereby the mounting angle of the connector cover 10 </ b> A with respect to the connector 20 can be changed. That is, the connector cover 10A can be attached to the connector 20 both vertically and horizontally as shown in FIGS. By changing the attachment angle in this manner, the direction in which the electric wire 80 is guided by the connector cover 10A can be changed.

  As shown in FIG. 2, the connector cover 10 </ b> A is formed in a bottomed cylindrical shape having a bottom surface 12 and four side surfaces and has an opening 11. As shown in FIGS. 3 and 4, the connector cover 10 </ b> A is assembled from the opening 11 side to the drawing surface 25 side of the housing 21. Locking holes 15 that are locked to the locking protrusions 24 described above are formed at the four corners on the opening 11 side of the connector cover 10A. Further, the connector cover 10A has branch wire outlets 17 formed on the respective side surfaces facing each other, and a branch wire 81 is drawn from the branch wire outlet 17 as shown in FIGS.

  Further, the connector cover 10 </ b> A has a rectangular extension 13 extending from the bottom surface 12 in a direction perpendicular to the bottom surface 12, and a band insertion hole 14 is formed in the extension 13. The band insertion hole 14 is formed through each side surface of the extending portion 13. The band portion 9 of the binding band 7 is inserted into the band insertion hole 14. The binding band 7 is made of synthetic resin, and is formed by integrally molding the band portion 9 and the fixing portion 8 as shown in FIG. The binding band 7 is fixed to the connector cover 10 </ b> A when the fixing portion 8 prevents the band portion 9 from coming off while the band portion 9 is inserted into the band insertion hole 14. As shown in FIGS. 3 and 4, the binding band 7 is attached to the connector cover 10 </ b> A and firmly binds the trunk line 82. Thus, the connector cover 10A is a bundling connector cover that binds the trunk line 82 with the bundling band 7, and is different from the connector cover 10C according to the prior invention that is an insertion type connector cover.

  Further, the extending portion 13 has a band insertion hole 14 penetrating in a first direction (for example, the vertical direction) and intersects the first direction (in the example of FIG. 2, it is orthogonal) in a second direction ( For example, a band insertion hole 14 penetrating in the left-right direction.) Is provided. The band portion 9 can be inserted into each of the band insertion holes 14. That is, the connector cover 10 </ b> A has a plurality of band insertion holes 14 in which the binding bands 7 are inserted in different directions. For this reason, the binding band 7 can be attached to the connector cover 10A in different insertion directions. Therefore, the bundling direction can also be changed according to the routing direction of the trunk lines 82 to be bound. For example, the example shown in FIG. 3 shows a state in which the trunk line 82 is routed in the left-right direction in the figure and the trunk line 82 is bound in the up-down direction, but the attachment angle of the connector cover 10A is changed from the state. The main line 82 can be routed vertically and the main line 82 can be bundled in the left-right direction.

  Next, the second binding type connector unit 30B will be described. Fig.5 (a) is a perspective view which shows the connector cover of a 2nd binding type connector unit, FIG.5 (b) is a side view of Fig.5 (a). FIG. 6 is a perspective view showing a usage state of the second binding type connector unit. The same components as those of the first binding connector unit 30A described above are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIGS. 5A and 5B, the second binding type connector unit 30B includes a connector 20 that is common to the first binding type connector unit 30A, and a connector that is assembled to the drawing surface 25 side of the connector 20. And a cover 10B. All of these members are formed of a synthetic resin.

  As shown in FIGS. 5A and 5B, the connector cover 10 </ b> B is formed in a bottomed cylindrical shape having a bottom surface 12 and four side surfaces and has an opening 11. As shown in FIG. 6, the connector cover 10 </ b> B is assembled from the opening 11 side to the drawing surface 25 side of the housing 21. Locking holes 15 that are locked to the locking protrusions 24 are formed at the four corners on the opening 11 side of the connector cover 10B. Thereby, similarly to the above-described first bundling connector unit 30A, the connector cover 10B can be rotated by 90 ° from the mounting angle in addition to the mounting angle shown in FIG. 6 (that is, both vertically and horizontally). And can be attached to the connector 20. Further, the connector cover 10B has branch wire outlets 17 formed on the respective side surfaces facing each other, and branch wires 81 are drawn from the branch wire outlets 17 as shown in FIG.

  Further, the connector cover 10B has a binding band portion 57 provided integrally with the bottom surface 12. The binding band portion 57 includes a fixing portion 58 that extends from one end side of the bottom surface 12 in a direction perpendicular to the bottom surface 12, and a band portion 59 that extends from the other end side of the bottom surface 12. . A fixing hole 58B is formed in the fixing portion 58, and the band portion 59 is inserted into the fixing hole 58B to be prevented from coming off. The binding band portion 57 firmly binds the connector cover 10B and the trunk line 82 as shown in FIG. That is, the connector cover 10B is also a bundling connector cover like the connector cover 10A, and is different from the connector cover 10C according to the prior invention which is an insertion type connector cover. In addition, the band part 59 shown with a broken line in FIG.5 (b) has shown the state before binding.

  Next, a routing method using the above-described first binding type connector unit 30A, the second binding type connector unit 30B, and the insertion type connector unit 30C will be described. FIG. 7 is a plan view showing a wiring form of the electric wire using the wiring structure according to the embodiment. FIG. 8 is a diagram for explaining the function and effect of the connector unit according to the embodiment, and FIG. 8A is a perspective view showing an example of a wiring form when the connector unit according to the prior invention is used. FIG.8 (b) is a perspective view which shows an example of the wiring form at the time of using the connector unit which concerns on embodiment.

  In the present embodiment, as shown in FIG. 7, the electric wires 80 are used using the seven connector units 30 </ b> A to 30 </ b> C so that the mating connectors 40 can be sequentially fitted to the counterpart connectors 40 fixed to the seven solenoids 50 shown in FIG. 1. An example of regulating the routing route will be described. The arrangement order and ratio of the connector units 30A to 30C shown in FIG. 1 are merely examples, and any connector unit selected from the connector units 30A to 30C can be arranged for each counterpart connector 40.

  3 and 4 for the first binding type connector unit 30A, FIG. 6 for the second binding type connector unit 30B, and FIG. 11 for the insertion type connector unit 30C, as described with reference to FIG. When the cable is used, the trunk line 82 from the adjacent connector units 30A to 30C is bound by the binding band 7 or the binding band part 57, or is inserted through the wire insertion port 16 and passes through the connector cover 10C. And the branched branch line 81 merge to form a trunk line 82 routed to the next connector unit 30A to 30C side. As described above, in the connector units 30A to 30C, the routing directions of the branch lines 81 and the trunk lines 82 are guided by the connector covers 10A to 10C.

  By sequentially routing the electric wires 80 in this manner, for example, as shown in FIG. 7, the routing directions of the branch lines 81 and the trunk lines 82 can be appropriately guided to regulate the routing route.

  In particular, in the example of the routing form shown in FIG. 7, the first binding type connector unit 30A and the second binding type connector unit 30B are used as the connector units. According to the first binding type connector unit 30A and the second binding type connector unit 30B, as described above, the trunk line 82 is bound by the binding band 7 or the binding band part 57, and the binding type connector units 30A, 30B and the trunk line 82 are Is firmly fixed. For this reason, it is possible to prevent the entire bundling connector units 30 </ b> A and 30 </ b> B from rotating with respect to the main line 82, and to improve attachment workability when attaching the connector 20 to the mating connector 40.

  Further description will be made with reference to FIG. 8. In the case of a wiring configuration using only the insertion type connector unit 30 </ b> C (in the case of the wiring configuration of FIG. 10 described above), in the insertion type connector unit 30 </ b> C, the main line is connected to the wire insertion port 16. Since only the terminal 82 is inserted, the connector unit 30C may rotate with respect to the electric wire 80 as shown in FIG. Thus, if the orientation of the connector 20 is difficult to align, the workability of attaching the connector 20 to the mating connector 40 is not good. On the other hand, in the routing form of the present embodiment, the entire bundling connector units 30A and 30B are prevented from rotating with respect to the main line 82 as described above, and is shown in FIG. As described above, the orientation of the plurality of connectors 20 can be easily aligned, so that the mounting workability is improved.

  As described above, the arrangement order and ratio of the connector units 30A to 30C shown in FIGS. 1 and 7 are examples, and for example, the first binding connector unit 30A is fitted to all the mating connectors 40. It is good also as a structure. However, when the routing route of the electric wire 80 is regulated using the plurality of connector units 30A to 30C, it is not always necessary to prevent the rotation with respect to the main line 82 in all the connector units 30A to 30C.

  Accordingly, as in the arrangement structure shown in FIGS. 1 and 7, the configuration includes both the bundling connector units 30A and 30B and the insertion type connector unit 30C. , 30B, and the insertion type connector unit 30C can be arranged at other locations. With such a configuration, it is possible to reduce the number of bundling connector units 30A and 30B that require bundling work and are expensive in product cost.

  As for the first binding type connector unit 30 </ b> A, any type of binding band 7 can be attached to the connector cover 10 </ b> A as long as it has the band portion 9 that can be inserted into the band insertion hole 14. For example, a plurality of types of bundling bands 7 having different lengths of the band portion 9 are prepared, and a bundling band 7 of a type suitable for the number of main lines 82 to be bundled (that is, the thickness of the main line 82) is selected and used. It is assumed that

  In addition, since the first bundling connector unit 30A has a relatively large number and can bind the trunk wires 82 of a relatively thick portion as described above, as shown in FIGS. 1 and 7, the insertion type connector unit 30C. It can arrange | position in the thick site | part in the trunk line 82 rather than. In FIG. 1 and FIG. 7, since the number of trunk lines 82 increases and becomes thicker toward the left side in the drawing, the first bundling connector unit 30A is arranged on the left side of the insertion type connector unit 30C. . That is, as the wiring structure shown in FIGS. 1 and 7, the configuration includes both the binding type connector unit (the first binding type connector unit 30A or the second binding type connector unit 30B) and the insertion type connector unit 30C. The bundling connector units 30A and 30B can be arranged at locations where a relatively large number of trunk lines 82 are routed, and the insertion type connector unit 30C can be arranged at other locations.

  Alternatively, it is assumed that a plurality of types of binding bands 7 formed of synthetic resins having different heat resistance characteristics are prepared, and the types of binding bands 7 suitable for the use environment are selected and used. For example, when the first binding connector unit 30A is used in the mission case 70, depending on the specifications of the mission case 70, heat resistance to a relatively high temperature range of about 150 ° C. to 160 ° C. is required. In some cases, heat resistance for only a relatively low temperature range of about 80 ° C. to 90 ° C. may be sufficient. In such a case, it is conceivable to use a binding band 7 having a high heat resistance that can be used in any use environment, but using a synthetic resin with good heat resistance increases the cost. On the other hand, if high heat resistance is not required, the cost can be reduced if the binding band 7 that can be used only in a low temperature range is selected and used.

  Further, since the first binding type connector unit 30A can be used without attaching the binding band 7 when binding is not required, whether or not the binding band 7 is attached can be changed according to the application.

  Further, in the second binding type connector unit 30B, since the binding band portion 57 is formed integrally with the connector cover 10B, the binding work can be easily performed as compared with the case where a separate binding band is attached. .

Below, the connector unit and wiring structure which concern on embodiment are summarized.
