JP 2009-2224040 A

  By the way, as a connector of a wire harness, a connector having a substantially circular cross section, that is, a so-called round connector may be used. In general, since the connector is fixed on a flat surface, it is not easy to fix such a connector having a substantially circular cross section.

  On the other hand, the Patent Document 1 does not include details of a structure for fixing the connector to the bracket or for fixing a connector having a substantially circular cross section.

  An object of the technology of the present disclosure is to make it possible to stably fix, for example, a connector having a substantially circular cross section in a vehicle or the like.

The technology of this disclosure is:
Connector fixing structure,
An opening section forming section that forms an opening section for fitting at least a part of the connector;
In order to keep the connector in a state of being fitted into the opening, there is provided a fixing structure for a connector, including a fixing member attaching portion configured to attach a fixing member.

  Preferably, the opening section forming portion and the fixing member mounting portion are provided on a single bracket fixed to a base member to be mounted on the vehicle.

  When the connector is a connector having a substantially circular cross section, the opening is preferably substantially rectangular.

  The technique of this indication exists also in the bracket for connector fixation. The bracket has an opening section forming section for forming an opening section into which at least a part of the connector is fitted, and a fixing member to keep the connector in a state of being fitted into the opening section. It is good to provide the fixing member attaching part comprised in this way.

  According to the technology of the present disclosure, since the above-described configuration is provided, in a vehicle or the like, for example, a connector having a substantially circular cross section can be stably fixed.

It is the schematic diagram which applied the fixing structure of the connector which concerns on this embodiment, and looked at the part of the vehicle with which the connector was fixed from the vehicle upper direction. It is the II-II sectional view taken on the line of FIG. (A) is a top view of a part of the bracket in the connector fixing structure according to the present embodiment, and (B) is a plan view of the connector fitted in the hole of the bracket of (A) and its surroundings. It is a figure showing the place where the connector was fixed to the bracket of Drawing 3 (A) in the fixing structure of the connector concerning this embodiment, (A) is a top view and (B) is a side view.

  The connector fixing structure according to the present embodiment will be described below with reference to the accompanying drawings. The same parts are denoted by the same reference numerals, and their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

  FIG. 1 is a schematic view of a part of a vehicle 1 to which a connector is fixed as viewed from above the vehicle by applying a connector fixing structure (hereinafter simply referred to as “fixing structure”) 10 according to the present embodiment. is there.

  The vehicle 1 includes a chassis frame F. More specifically, the vehicle 1 includes a pair of left and right side members 14 extending in the vehicle front-rear direction, and a plurality of cross members 16 extending between the side members 14 in a direction substantially orthogonal thereto. . Although only three cross members 16 are shown in FIG. 1, this does not limit the number of cross members, and does not limit the arrangement location. A cab (cabin) 18 is provided on the front side in the vehicle front-rear direction. The vehicle 1 is a cab over type vehicle in which an engine (not shown) as a power source is disposed below the cab 18, but this is intended to limit the types of vehicles to which the technology of the present disclosure is applied. Furthermore, the power source is not limited to the engine. Further, a pair of left and right brake lamps 20 are disposed at the position of the rearmost cross member 16 'at the rear end in the vehicle front-rear direction.

  The fixing structure 10 according to this embodiment includes a connector (hereinafter referred to as a first connector) 26 attached to an end portion of a wire harness (hereinafter referred to as “harness”) 24 extending from a control device 22 mounted on the cab 18. Applied to fixing. In FIG. 1, a connector (hereinafter referred to as a second connector) 30 provided at the end of a harness 28 connected to the brake lamp 20 is connected to the first connector 26. Note that the fixing structure 10 may be applied to the second connector 30 of the harness 28 instead of being applied to the first connector 26 of the harness 24 extending from the control device 22. However, although detailed description is omitted, the control device 22 is, for example, an electronic control unit (ECU) itself or a part thereof, has a configuration as a computer, and has a functional unit corresponding to a brake lamp control unit. The control device 22 is connected to a brake lamp switch that is turned on from an OFF state when a brake pedal is operated by a driver. However, the configuration of the control device 22 is not limited to this.

  FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 1, but illustration of the configuration in the first connector 26 is omitted. The fixing structure 10 includes a single bracket 32. The bracket 32 is substantially U-shaped in cross section (with a shape in a cross section orthogonal to the vehicle longitudinal direction) in a state of being fixed to the vehicle in FIG. Here, the bracket 32 is formed by bending an iron plate having a predetermined thickness. However, this does not limit the constituent material and the manufacturing method of the bracket 32, and the bracket 32 can be manufactured by various materials and methods.

  The bracket 32 includes a connector fixing portion 34 and a vehicle side fixing portion 36. Since the bracket 32 has a substantially U-shaped cross section as described above, the connector fixing portion 34 and the vehicle side fixing portion 36 are opposed to each other as shown in FIG. The vehicle side fixing portion 36 located at one end of the bracket 32 is fixed to the side member 14 on the left side of the vehicle (left side in FIG. 1) by bolt fastening (of the mechanical joining means). For this purpose, the vehicle side fixing portion 36 of the bracket 32 is provided with a through hole through which the bolt B is inserted, and the side member 14 is also provided with a through hole through which the bolt is inserted. The bracket 32 may be fixed to the side member 14 by mechanical joining means other than bolt fastening or metallurgical joining means such as welding. In addition, the bracket 32 is fixed to the side member 14 as a base member to be attached to the vehicle, but may be fixed to another member, for example, the side member 14 on the right side of the vehicle or the cross member 16. Alternatively, the bracket 32 may be used for fixing the connector in the cab 18.

  FIG. 3A is a plan view of a part of the bracket 32, particularly a part corresponding to the connector fixing part 34, and FIG. 3B is a plan view of the first connector 26 of the harness 24 fixed to the connector fixing part 34. FIG. 3A shows the connector fixing portion 34 when the bracket 32 fixed to the left side member 14 in FIG. 1 is viewed from the right side member 14 side. In FIG. 3, the connector 26 is schematically shown. This is the same in FIG.

  As is clear from FIGS. 2 and 3A, the connector fixing portion 34 of the bracket 32 having a substantially U-shaped cross section has a flat plate shape. As shown in FIG. 3A, the connector fixing portion 34 is formed with a hole 40 and a pair of fixing holes 42 and 44. The hole 40 is rectangular, that is, the shape of the opening is square, and is provided here as a hole or opening for fitting the first connector 26. That is, the portion around the hole 40 in the connector fixing portion 34 is an opening section forming portion that forms the hole 40 as an opening into which the first connector 26 can be fitted. The hole 40 may be provided with a recess such as a notch at its edge so as to facilitate removal of the connector fitted therein. It should be rectangular.

  The fixing holes 42 and 44 of the connector fixing portion 34 are holes to which fixing bands 46 shown in FIG. 4 are attached. The fixing band 46 is a fixing member. Accordingly, the portion around the fixing holes 42 and 44 corresponds to the fixing member mounting portion. As is clear from FIGS. 1 to 3, the fixing holes 42 and 44 are positioned on the vehicle front side of the hole 40. This is because the electric wire part (for example, electric wire bundle part) 48 which has the 1st connector 26 in the edge part is extended in the vehicle front side of the 1st connector 26. FIG. However, these do not limit the positional relationship of the holes 40, 42, 44. In the vehicle 1 of FIG. 1, the fixing holes 42 and 44 are aligned in the vertical direction.

  Here, the first connector 26 of the harness 24 will be described. The first connector 26 is a so-called round connector, and is a member having an axis 26 </ b> A and having a substantially cylindrical shape. More specifically, the first connector 26 in the present embodiment includes two portions with different diameters positioned so as to be aligned along the axis 26A. In the following, for ease of explanation, of the two portions of the first connector 26 that is a female connector, the end portion of the harness 28, that is, the connection into which the second connector 30 that is a male connector is inserted. A portion where a terminal portion (not shown) opens is referred to as a housing main body portion 50. Of the two parts, the part where the electric wire part 48 extends is referred to as a housing extension part 52. The housing body 50 and the housing extension 52 can each be regarded as a substantially cylindrical shape. And since the housing main-body part 50 is larger diameter than the housing extension part 52, the housing main-body part 50 may be called a large diameter part, and the housing extension part 52 may be called a small diameter part. Thus, the 1st connector 26 is substantially circular in the cross section orthogonal to the axis line 26A over the whole. Here, the term “substantially circular” as a cross section may include not only those whose cross section is a perfect circle or an ellipse, but also those having protrusions or recesses on the outer peripheral surface thereof, those having one or a plurality of grooves, etc. . As will be apparent from the description below, the first connector 26 is fixed to the bracket 32 with the housing body 50 fitted in the hole 40. Therefore, the housing main body 50 corresponds to a coupling portion for the hole 40 of the bracket 32 in the first connector 26.

  Next, the dimensional relationship between the square hole 40 of the bracket 32 and the first connector 26 having a substantially circular cross section will be described. In particular, since it is the housing main body portion 50 of the first connector 26 that fits into the hole 40, the dimensions of the hole 40 and the housing main body portion 50 (as the coupling portion) of the first connector 26 are as follows. The relationship will be described below.

  In the present embodiment, as shown in FIG. 3A, the hole 40 has a rectangular shape, that is, a rectangular shape. Here, in FIG. 3A, the length of the long side (opening length) of the hole 40 is defined as L1, and the length of the short side (perpendicular to the long side) (opening width) is defined as W1. (Here, the bracket 32 is provided in the vehicle 1 so that the long side of the hole 40 extends in the vehicle front-rear direction in the vehicle 1 of FIG. 1, but this limits the direction of the bracket 32 and the hole 40, etc. On the other hand, in FIG. 3B, the length (coupling portion length) of the housing main body 50 (in the direction of the axis 26A) of the first connector 26 is regarded as L2, and the housing main body 50 is regarded as a cylinder. The diameter (the maximum dimension in the cross section of the joint in the direction orthogonal to the length direction of the joint, that is, the maximum width of the joint) is defined as W2. Between these, the relationship of the following (1) Formula and (2) Formula is formed.

L1> L2 (1)
W1 <W2 (2)
Hereinafter, the fixing of the first connector 26 to the connector fixing portion 34 of the bracket 32 provided with such holes 40 and the like will be described with reference to FIGS. 4 (A) and 4 (B).

  Since the hole 40 has the relationship of the above formulas (1) and (2) with the housing main body 50 of the first connector 26, the housing main body 50 cannot pass through the hole 40. Here, the hole 40 is designed so that a part of the housing main body 50 protrudes to the back side of the connector fixing portion 34 when the housing main body 50 is disposed in the hole 40, that is, when the housing main body 50 is fitted. . Therefore, the housing main body 50 (a part) of the first connector 26 can be sufficiently fitted into the hole 40 (the operator fits the housing main body 50 of the first connector 26 into the hole 40. be able to).

  Then, the fixing band 46 is attached to the fixing holes 42 and 44 in order to keep the first connector 26 in such a state that the housing main body 50 is fitted in the hole 40 in this way. Here, the fixing band 46 is a resin binding band. At this time, the housing extension part 52 is positioned between the fixing band 46 and the connector fixing part 34 so as to press the housing extension part 52 of the first connector 26 against the connector fixing part 34 of the bracket 32. Therefore, by tightening the fixing band 46 inserted through the fixing holes 42 and 44, the housing extension portion 52 of the first connector 26 is fixed to the connector fixing portion 34, and thus is fitted in the hole 40. The housing main body 50 of the first connector 26 is fixedly held by the connector fixing portion 34.

  The bracket 32 to which the fixing structure 10 described above is applied has a hole 40 as an opening into which a part of the housing body 50 of the first connector 26 can be fitted, and a fixing hole to which the fixing band 46 is attached. The connector fixing part 34 provided with 42 and 44 is provided. Therefore, as described above, the housing main body 50 of the first connector 26 having a substantially circular cross section can be stably fixed to the bracket 32. As shown in FIGS. 1 and 2, the bracket 32 is fixed to the side member 14 as a base member of the vehicle 1 via the vehicle side fixing portion 36. Therefore, by using the bracket 32 to which the fixing structure 10 is applied, the first connector 26 having a substantially circular cross section can be stably fixed in the vehicle 1.

  The hole 40 is sized to fit the size of the first connector 26 or the housing main body 50 so as to further suppress the movement of the housing main body 50 of the first connector 26 fitted and fixed therein. It is good to have. That is, when the first connector 26 is fitted in the hole 40, it is better that there is less play around the first connector 26.

  In addition, this indication is not limited to the above-mentioned embodiment, In the range which does not deviate from the meaning of this indication, it can change suitably and can implement.

  For example, the connector fixed to the bracket 32 is not limited to having a substantially circular cross section. For example, a bracket having the above-described configuration may be applied to fixing a connector having a substantially polygonal cross section, such as a connector having a regular hexagonal cross section. In this case, the hole 40 is not limited to a rectangular shape, and may be designed in a shape corresponding to the shape of the connector. In the above embodiment, only the housing main body 50 of the first connector 26 is fitted into the hole 40, but the housing extension 52 is also fitted into the hole 40 in addition to the housing main body 50. The hole 40 may be designed.

  Moreover, in the said embodiment, the hole 40 was dividedly formed in the bracket 32 as an opening part which can fit the housing main-body part of a 1st connector. One reason is that the formation of the holes 40 is relatively easy. However, the opening in which at least a part of the connector can be fitted is not limited to the hole, and may be a recess, for example.

  Further, the fixing band 46 is not limited to being used for the housing extension portion 52 of the first connector 26, and may be used for the housing main body portion 50. However, in this case, when the housing main body portion 50 of the first connector 26 has a protrusion for releasing the connection of the second connector 30, the fixing band 46 is used so as not to apply pressure to the protrusion. It should be done.

  Further, the fixing band 46 is not limited to being used for the first connector 26 itself, and may be used for a wire portion of a harness having the first connector 26 at the end. However, in this case, the portion of the electric wire portion in the vicinity of the first connector 26 is preferably tightened with the fixing band 46 so as to keep the first connector 26 firmly fitted in the hole of the connector fixing portion.

  In addition, a second fixing member, specifically, a second fixing band may be supplementarily used. The second fixing band can be used, for example, for the second connector of the harness 28 or the electric wire portion extending therefrom. The second fixing band may be the same as the fixing band 46, and may have a different configuration, for example.

  For example, in the above-described embodiment, the bracket 32 having a substantially U-shaped cross section is used. However, the bracket 32 may be rectangular, inverted L-shaped, substantially T-shaped, V-shaped, etc. The cross-sectional shape can be changed as appropriate. Moreover, the connector fixing | fixed part 34 is not limited to being formed in flat form or having a plane, For example, you may have a curved surface in at least one part. Moreover, although the bracket 32 was comprised as a single member in the said embodiment, it is not limited to being a single member. For example, the bracket is divided into two members: a member having the hole 40 (member of the opening section forming portion) and a member having the fixing holes 42 and 44 (member of the fixing member attaching portion). It may be combined at the time of use. Note that the opening section forming portion and the fixing member attaching portion are not limited to being provided on the bracket, and may be provided directly on the base member as described above.

  In the above embodiment, the fixing band 46 is a resin binding band, but the fixing band may be made of other materials or may have other configurations. For example, the fixing band 46 may be a simple band member or a string-like member. For example, a metal band portion and a fastening member (for example, made of a bolt and a nut) for fixing the ends of the band portion to each other. It may be provided with. For example, the fixing band may be configured as a clip-type member. Of course, the arrangement, shape, size, etc. of the holes in the fixing member mounting portion may be determined according to the fixing member. Depending on the fixing member, a groove or a convex portion extending to the end of the bracket instead of the hole may be used. Or a recessed part etc. may be provided.

  Moreover, in the said embodiment, the bracket 32 was used for fixation of the connector of the harness to which the harness extended from a brake lamp is connected. However, the fixing structure or bracket of the technology of the present disclosure can also be used for fixing the connector of the harness between other electrical devices. In addition, the fixing structure or the bracket according to the technology of the present disclosure is not limited to fixing the connector in the vehicle, and can be applied to fixing the connector in other fields. Further, the bracket 32 is not limited to being used for fixing the connector itself provided at the end of the harness, and a connector provided at the end of the harness and a connector provided at the end of another harness. It may be used to fix a connector used between them for the connection.
