Description

This invention relates to a harness fastener that can hold a wire harness and fasten it to a fixed object.

Harness fasteners that can hold a wire harness and fasten it to a fixed object have been known (see Patent Document 1). Such harness fasteners are provided with a holding portion that holds the wire harness and a fastening portion that can fasten it to a fixed object.

In automobiles and other vehicles, the number of wire harnesses varies depending on the specifications. For this reason, it is possible to change the harness fastener depending on the number of wire harnesses. However, preparing multiple harness fasteners in advance leads to an increase in the number of parts and makes management more complicated.

One possible solution is to set a harness fastener for a specification with a large number of wire harnesses, and use the same harness fastener regardless of the number of wire harnesses. However, a harness fastener set for a specification with a large number of wire harnesses is wasteful in a specification with a small number of wire harnesses, and there is also the problem that it gets in the way of wiring work, etc.

JP 2009-19650 A

The present invention aims to provide a harness fixture that can change the number of wire harnesses it holds.

The present invention is a harness fastener that can hold multiple wire harnesses arranged side by side in a direction intersecting the longitudinal direction and can be fastened to a fastening object, and has multiple fastener bodies provided with holding parts that hold the wire harnesses, and the fastener bodies have a basic fastener body provided with a fastening part that can be fastened to the fastening object in addition to the holding parts, and an additional fastener body provided with a holding connecting part that connects by holding at least a part of the other fastener bodies in addition to the holding parts.

According to the present invention, the number of wire harnesses held can be changed.
More specifically, the harness fastener according to the present invention is capable of holding a plurality of wire harnesses arranged side by side in a direction intersecting the longitudinal direction and fastening them to a fastening object, and has a plurality of fastener bodies provided with holding portions for holding the wire harnesses. The fastener bodies have a basic fastener body provided with a fastening portion capable of fastening to a fastening object in addition to the holding portions, and an additional fastener body provided with a holding connecting portion that connects by holding at least a part of the fastener body in addition to the holding portions.
According to this configuration, the additional fixing device main body can be connected to the basic fixing device main body. Also, a separate additional fixing device main body can be connected to the additional fixing device main body connected to the basic fixing device main body. Therefore, when the additional fixing device main body is connected to the basic fixing device main body, two wire harnesses can be held. Also, when the separate additional fixing device main body is connected to the additional fixing device main body connected to the basic fixing device main body, three wire harnesses can be held. In this way, by preparing additional fixing device main bodies in a number equal to the number of wire harnesses minus one in addition to the basic fixing device main body and connecting these, all wire harnesses can be held. Therefore, the harness fixing device according to the present invention can change the number of wire harnesses that it holds.

As an aspect of the present invention, the holding connecting portion may be a housing connecting portion having a housing space formed therein for housing the holding portion of another fixing device body.
In the present invention, "accommodating the holding portion" is not limited to accommodating the entirety of the holding portion, and may be understood to mean accommodating the entirety or a part of the holding portion.

With this invention, the retaining portion of the fixing device main body is accommodated in the accommodating and connecting portion of the additional fixing device main body, so the harness fixing device can be made smaller than harness fixing devices that are connected via connecting portions protruding from each fixing device main body.

In another aspect of the present invention, the outer shape of the holding portion may be formed to have a polygonal cross-section, the inner shape of the accommodating connection portion may be formed to have a polygonal cross-section, and the outer surface of the holding portion and the inner surface of the accommodating connection portion may abut on at least two surfaces.
In the present invention, contact does not only refer to so-called surface contact, in which surfaces come into contact with each other, but may also refer to line contact, in which a surface comes into contact with a line, or point contact, in which a surface comes into contact with a point.

With this invention, the outer surface of the holding part and the inner surface of the housing connection part come into contact on at least two surfaces, so the additional fixing device body does not rotate around the connection part. This prevents the harness fixing device from bending due to the weight of the additional fixing device body or the weight of the wire harness.

As another aspect of the present invention, the holding portion may be provided with a fitting portion at a portion extending along the longitudinal direction, the fitting portion fitting into at least one of a recess or a protrusion formed on the outer circumferential surface of an exterior member that is attached to the wire harness.

With this invention, the fitting portion provided on the holding portion fits into a recess or protrusion of an exterior member that is attached to the wire harness, so that even if the wire harness is pushed or pulled in the longitudinal direction, the holding position of the wire harness in the longitudinal direction can be prevented from shifting.

As another aspect of the present invention, the housing connection part may be provided with a fitting part that fits into at least one of a recess or a protrusion formed on the outer circumferential surface of an exterior member that is fitted to the wire harness, at a portion that extends in the longitudinal direction further than the housed holding part.

With this invention, the fitting portion provided on the housing connection portion fits into the recess or protrusion of the exterior member that is attached to the wire harness, so that even if the wire harness is pushed or pulled in the longitudinal direction, the holding position of the wire harness in the longitudinal direction can be prevented from shifting.

As another aspect of the invention, in the additional fixing device main body, the holding portion has a first receiving portion that holds the wire harness and a first lid portion that closes the opening of the first receiving portion, and the housing connecting portion has a second receiving portion that houses the holding portion of the other fixing device main body and a second lid portion that closes the opening of the second receiving portion, and the first lid portion and the second lid portion are connected to each other to form a connected lid portion.

With this invention, by operating the connecting lid portion, it is possible to simultaneously open the openings of each receiving portion. Conversely, it is also possible to simultaneously close the openings of each receiving portion. This makes it easier to fit a wire harness or the holding portion of another fixing device body into each receiving portion. In addition, the direction in which the wire harness is fitted and the direction in which the holding portion of another fixing device body is fitted are the same, making these fitting operations easier.

As a further aspect of the present invention, a support portion may be provided for supporting the connecting lid portion so as to be pivotable relative to at least one of the first receiving portion and the second receiving portion.
According to the present invention, the connecting lid can be opened and closed while at least one of the receiving parts and the connecting lid are connected to each other. Therefore, it is possible to prevent at least one of the receiving parts and the connecting lid from being separated when fitting a wire harness or a holding part of another fixing device body into each receiving part. It is also possible to reduce the number of parts.

As a further aspect of the present invention, a locking portion may be provided to at least one of the first receiving portion and the second receiving portion, for locking the connected lid portion in a closed state.
According to the present invention, the connecting lid can be locked by simply closing the connecting lid on at least one of the receiving parts. Therefore, the connecting lid can be quickly closed and held when fitting the holding parts of the wire harness or other fixing device main body into each receiving part. It is also possible to release the lock and lock it again.

The present invention allows you to change the number of wire harnesses that are held.

And FIG. 20 is an explanatory diagram of a situation in which the harness fixing device 1 is attached to the chassis frame Cf and a situation in which the harness fixing device 1 is attached to the connector box Cb. In FIG. 20, only the fixing portion 4 is shown in cross section so that the bolt gripping portion 42 and the cassette engagement portion 43 that constitute the fixing portion 4 can be seen.

In this application, the directions of the harness fixing device 1 are indicated in all drawings. In more detail, arrow F indicates the forward side, arrow B indicates the rearward side, arrow L indicates the leftward side, and arrow R indicates the rightward side. Arrow U indicates the upward side, and arrow D indicates the downward side. In addition, in this application, the front-to-back direction is described as X, the left-to-right direction as Y, and the up-down direction as Z.

As shown in Figure 1, the harness fixing device 1 can connect an additional fixing device main body 5 to the basic fixing device main body 2. Also, as shown in Figures 18 and 19, the harness fixing device 1 can connect a separate additional fixing device main body 5 to the additional fixing device main body 5 connected to the basic fixing device main body 2. In this way, the harness fixing device 1 can hold all of the exterior-mounted harnesses WH by preparing additional fixing device main bodies 5 in the number obtained by subtracting one from the number of exterior-mounted harnesses WH in addition to the basic fixing device main body 2 and connecting these. The basic fixing device main body 2 and the additional fixing device main body 5 are described below.

As shown in Figures 2 to 7, the basic fixing device main body 2 has a holding part 3 that holds the exterior harness WH, and a fixing part 4 that can be fixed to the target object, such as a chassis frame Cf (see Figures 20(a) and 20(b)). The basic fixing device main body 2 is an injection molded product made of a resin material such as polypropylene.

The holding part 3 has a receiving part 31 formed in a substantially rectangular parallelepiped shape and a lid part 32 that closes an opening formed on one side of the receiving part 31. The holding part 3 also has a support part 33 that supports the lid part 32 so that it can pivot relative to the receiving part 31, and a locking part 34 (see Figures 3(b) and 5(a)) that locks the lid part 32 in a closed state relative to the receiving part 31.

The receiving portion 31 has an upper plate 310 perpendicular to the vertical direction Z, a front plate 311 arranged along the front edge of the upper plate 310, and a rear plate 312 arranged along the rear edge of the upper plate 310. The front plate 311 and the rear plate 312 extend from the upper plate 310 toward the downward side D and are parallel to each other. Thus, an opening 30 (see FIG. 6) is formed between the lower end portion of the front plate 311 and the lower end portion of the rear plate 312. An insertion space Sa is formed inside the receiving portion 31 in the left-right direction Y, through which the exterior harness WH is inserted.

The receiving portion 31 is also provided with ribs 31r that protrude toward the central axis of the insertion space Sa. To explain in more detail, the end of the left side L of the receiving portion 31 is provided with three ribs 31r that protrude toward the central axis of the insertion space Sa, and the end of the right side R of the receiving portion 31 is also provided with three ribs 31r that protrude toward the central axis of the insertion space Sa. These ribs 31r are in an inverted U shape with the upper side U connected in an arc shape when viewed from the left side L or right side R. Therefore, these ribs 31r are fitted into the recesses of the corrugated tube C that is fitted from the lower side D (see Figures 6 and 16(b)).

When the opening 30 is closed, the lid 32 has a pivot plate 320 that is perpendicular to the vertical direction Z, and a rear edge plate 322 that is arranged along the rear edge of the pivot plate 320. The rear edge plate 322 extends from the pivot plate 320 toward the upper side U and is connected to the rear plate 312 via a resin plate 331 described below. Therefore, when the tip portion 32t of the pivot plate 320 is pivoted in a direction away from the lower end portion of the front plate 311, the opening 30 opens (see FIG. 6). Conversely, when the tip portion 32t of the pivot plate 320 is pivoted in a direction approaching the lower end portion of the front plate 311, the opening 30 closes (see FIG. 7).

The lid 32 is also provided with ribs 32r that protrude toward the central axis of the insertion space Sa. More specifically, the end of the left side L of the lid 32 is provided with three ribs 32r that protrude toward the central axis of the insertion space Sa, and the end of the right side R of the lid 32 is also provided with three ribs 32r that protrude toward the central axis of the insertion space Sa. These ribs 32r are U-shaped with the lower side D connected in an arc shape when viewed from the left side L or right side R. Therefore, these ribs 32r are fitted into the recesses of the corrugated tube C when the lid 32 is closed on the receiving portion 31 (see Figures 7 and 16(b)).

The support portion 33 supports the lid portion 32 so that it can pivot freely relative to the receiving portion 31. The support portion 33 is configured by connecting one side of the lower end portion of the rear side plate 312 along the left-right direction Y and one side of the upper end edge of the rear edge plate 322 along the left-right direction Y with a resin plate 331.

The resin plate 331 is formed to be thinner than the rear plate 312 and the rear edge plate 322, and can bend or extend in the rotational direction around an imaginary axis along the left-right direction Y. Therefore, the support portion 33 allows the tip portion 32t of the pivot plate 320 to pivot in a direction away from or toward the lower end portion of the front plate 311.

The locking portion 34 allows the lid portion 32 to lock onto the receiving portion 31 when the lid portion 32 is closed. The locking portion 34 is composed of a locking piece 341 provided on the tip portion 32t of the pivot plate 320 and a locking ring 342 provided on the lower end portion of the front side plate 311.

The locking piece 341 is formed perpendicular to the pivot plate 320 at the tip portion 32t of the pivot plate 320. When the pivot plate 320 closes the opening portion 30, the locking piece 341 is a plate with a rectangular cross section that is short in the front-rear direction X and long in the left-right direction Y, and has a locking claw 34f formed on its front surface (see Figures 3(b) and 5(a)).

The locking ring 342 is formed in a generally rectangular tube shape with a horizontal plate 34h arranged parallel to the front plate 311 at a predetermined distance, and a pair of support plates 34s arranged perpendicular to the front plate 311 and parallel to each other at a predetermined distance (see Figures 3(b) and 5(a)). A through hole is formed on the inside of the locking ring 342, penetrating in the vertical direction Z. Therefore, when the locking piece 341 is inserted into the locking ring 342, the locking claw 34f of the locking piece 341 hooks onto the horizontal plate 34h that constitutes the locking ring 342.

The fixing part 4 is mainly composed of a receiving part 41 formed in a substantially rectangular parallelepiped shape. The fixing part 4 also has a bolt gripping part 42 that can grip a stud bolt B protruding from, for example, the chassis frame Cf (see FIG. 20(a)), and a cassette engaging part 43 that can engage with a lock plate P provided on, for example, the connector box Cb (see FIG. 20(b)).

The receiving portion 41 has an intermediate plate 410 that is perpendicular to the vertical direction Z, a front side plate 411 that is arranged along the front edge of the intermediate plate 410, a left side plate 412 that is arranged along the left edge of the intermediate plate 410, and a right side plate 413 that is arranged along the right edge of the intermediate plate 410. The front side plate 411 extends from the intermediate plate 410 toward the upper side U and the lower side D, and is parallel to the front side plate 311 described above. The left side plate 412 and the right side plate 413 also extend from the intermediate plate 410 toward the upper side U and the lower side D, and are parallel to each other.

The bolt gripping portion 42 is attached so as to sandwich the intermediate plate 410. The bolt gripping portion 42 has a cylindrical body 420 with an enlarged diameter at the upper end. The bolt gripping structure 421 is provided inside the cylindrical body 420 (see Figs. 4(b) and 5(b)). The bolt gripping structure is composed of a pair of gripping pieces 422, 423, one of which, the gripping piece 422, extends diagonally downward to the right from the center position in the vertical direction Z, and the other gripping piece 423, extends diagonally downward to the left from the center position in the vertical direction Z. A locking claw 42f is formed on each of the gripping pieces 422, 423.

Although the gripping pieces 422, 423 are symmetrical to each other, they are displaced in the vertical direction Z by half the pitch length of the stud bolt B (see FIG. 20(a)). That is, the gripping piece 422 is disposed at a position displaced downward D by half the pitch length of the stud bolt B from the gripping piece 423. In other words, the gripping piece 423 is disposed at a position displaced upward U by half the pitch length of the stud bolt B from the gripping piece 422. Therefore, the locking claw 42f of the gripping piece 422 and the locking claw 42f of the gripping piece 423 are both caught in the spirally formed thread groove of the stud bolt B.

The cassette engagement portion 43 is provided integrally with the front side plate 411 at the center in the left-right direction Y on the front surface of the front side plate 411. The cassette engagement portion 43 is mainly composed of an engagement plate 431 and a pair of guide plates 432, 433 (see Figures 2(b) and 3(b)). The engagement plate 431 is arranged parallel to the front side plate 411 at a predetermined distance, except for the part connected to the front side plate 411. The center part of the engagement plate 431 in the left-right direction Y is cut out from the upper edge to the middle part in the up-down direction Z. Therefore, the engagement plate 431 is formed with a connecting part 43c that connects a part of the left side L and a part of the right side R. Such connecting part 43c functions as a locking piece.

The guide plates 432, 433 extend from the front side plate 411 toward the front side F. The guide plate 432 is disposed at a predetermined interval along the left edge of the engagement plate 431, excluding the portion connected to the engagement plate 431. The guide plate 433 is disposed at a predetermined interval along the right edge of the engagement plate 431, excluding the portion connected to the engagement plate 431. These guide plates 432, 433 are disposed in parallel with an interval slightly wider than the dimension in the left-right direction Y of the mating lock plate P (see FIG. 20(b)). Therefore, these guide plates 432, 433 function as guide plates that guide the lock plate P in a straight line.

As shown in Figures 8 to 14, the additional fixing device main body 5 has a holding portion 6 that holds the armored harness WH, and a holding connecting portion 7 that connects by holding a part of the basic fixing device main body 2. The holding connecting portion 7 connects by accommodating the holding portion 3, which is part of the basic fixing device main body 2, and will be described below as the accommodating connecting portion 7. The additional fixing device main body 5 is also an injection molded product made of a resin material such as polypropylene.

The holding part 6 has the same size and shape as the holding part 3 described above. The holding part 6 has a receiving part 61 formed in a substantially rectangular parallelepiped shape and a lid part 62 that covers an opening formed on one side of the receiving part 61. The receiving part 61 is connected to the rear side B of the receiving part 71 described below to form a connected receiving part 81, and the lid part 62 is connected to the rear side B of the lid part 72 described below to form a connected lid part 82. The holding part 6 also has a support part 83 that supports the connected lid part 82 so that it can pivot freely relative to the connected receiving part 81. The connected lid part 82 and the support part 83 will be described in detail later.

The receiving portion 61 has an upper plate 610 perpendicular to the vertical direction Z, a front plate 611 arranged along the front edge of the upper plate 610, and a rear plate 612 arranged along the rear edge of the upper plate 610. The front plate 611 and the rear plate 612 extend from the upper plate 610 toward the downward side D and are parallel to each other. Thus, an opening 60 (see FIG. 12) is formed between the lower end portion of the front plate 611 and the lower end portion of the rear plate 612. An insertion space Sb is formed inside the receiving portion 61 in the left-right direction Y, through which the armored harness WH is inserted.

The receiving portion 61 is also provided with ribs 61r that protrude toward the central axis of the insertion space Sb. To explain in more detail, the end of the left side L of the receiving portion 61 is provided with three ribs 61r that protrude toward the central axis of the insertion space Sb, and the end of the right side R of the receiving portion 61 is also provided with three ribs 61r that protrude toward the central axis of the insertion space Sb. These ribs 61r are inverted U-shaped with the upper side U connected in an arc shape when viewed from the left side L or right side R. Therefore, these ribs 61r are fitted into the recesses of the corrugated tube C that is fitted from the lower side D (see Figures 12 and 16(a)).

The storage connection part 7 is larger than the holding parts 3 and 6 described above. The storage connection part 7 has a receiving part 71 formed in a substantially rectangular parallelepiped shape and a lid part 72 that covers an opening formed on one side of the receiving part 71. The receiving part 71 is connected to the front side F of the receiving part 61 described above to form a connected receiving part 81, and the lid part 72 is connected to the front side F of the lid part 62 described above to form a connected lid part 82. The storage connection part 7 also has a locking part 84 that locks the connected lid part 82 in a closed state to the connected receiving part 81. The connected lid part 82 and the locking part 84 will be described in detail later.

The receiving portion 71 has an upper plate 710 perpendicular to the vertical direction Z, a front plate 711 arranged along the front edge of the upper plate 710, and a rear plate 712 arranged along the rear edge of the upper plate 710. The front plate 711 and the rear plate 712 extend from the upper plate 710 toward the lower side D and are parallel to each other. Thus, an opening portion 70 (see FIG. 13) is formed between the lower end portion of the front plate 711 and the lower end portion of the rear plate 712. An accommodation space Sc that accommodates the holding portion 3, which is a part of the basic fixing device main body 2, is formed inside the receiving portion 71. The accommodation space Sc is also an insertion space Sc through which the exterior harness WH is inserted. An opening portion 80 into which the fixing portion 4 of the basic fixing device main body 2 is inserted is formed in the center portion of the front plate 711 in the left-right direction Y.

The receiving portion 71 is provided with a rib 71r that protrudes toward the central axis of the insertion space Sc. To explain in detail, the end of the left side L of the receiving portion 71, which extends further to the left side L than the accommodated holding portion 3, is provided with three ribs 71r that protrude toward the central axis of the insertion space Sc, and the end of the right side R of the receiving portion 71, which extends further to the right side R than the accommodated holding portion 3, is also provided with three ribs 71r that protrude toward the central axis of the insertion space Sc. These ribs 71r are inverted U-shaped with the upper side U connected in an arc shape when viewed from the left side L or right side R. Therefore, these ribs 71r are fitted into the recesses of the corrugated tube C that is fitted from the lower side D (see Figures 13 and 16 (b)).

The connecting lid 82 has a pivot plate 820 that is perpendicular to the vertical direction Z when the opening portion 60 and the opening portion 70 are closed, and a rear edge plate 822 that is arranged along the rear edge of the pivot plate 820. The rear edge plate 822 extends from the pivot plate 820 toward the upper side U and is connected to the rear plate 612 via a resin plate 831 described later. Therefore, when the tip portion 82t of the pivot plate 820 is pivoted in a direction away from the lower end portion of the front plate 711, the opening portion 60 and the opening portion 70 are opened at the same time (see Figures 12 and 13). Conversely, when the tip portion 82t of the pivot plate 820 is pivoted in a direction approaching the lower end portion of the front plate 711, the opening portion 60 and the opening portion 70 are closed at the same time (see Figure 14).

In addition, the connecting lid portion 82 has a rib 62r that protrudes toward the central axis of the insertion space Sb on the lid portion 62, which is a part of the rear side B of the connecting lid portion 82. To explain in detail, the end of the left side L of the lid portion 62 has three ribs 62r that protrude toward the central axis of the insertion space Sb, and the end of the right side R of the lid portion 62 also has three ribs 62r that protrude toward the central axis of the insertion space Sb. These ribs 62r are U-shaped with the lower side D connected in an arc shape when viewed from the left side L or right side R. Therefore, these ribs 62r are fitted into the recesses of the corrugated tube C when the connecting lid portion 82 is closed on the connecting receiving portion 81 (see Figures 14 and 16(a)).

Furthermore, the connecting lid portion 82 is provided with a rib 72r that protrudes toward the central axis of the insertion space Sc on the lid portion 72, which is a part of the front side F of the connecting lid portion 82. To explain in detail, three ribs 72r that protrude toward the central axis of the insertion space Sc are provided on the end of the left side L of the lid portion 72, which is extended to the left side L from the housed holding portion 3, and three ribs 72r that protrude toward the central axis of the insertion space Sc are also provided on the end of the right side R of the lid portion 72, which is extended to the right side R from the housed holding portion 3. These ribs 72r are U-shaped with the lower side D connected in an arc shape when viewed from the left side L or right side R. Therefore, these ribs 72r are fitted into the recesses of the corrugated tube C when the connecting lid portion 82 is closed to the connecting receiving portion 81 (see Figures 14 and 16 (b)).

The support portion 83 supports the connecting lid portion 82 so that it can pivot freely relative to the connecting receiving portion 81. The support portion 83 is configured by connecting one side of the lower end portion of the rear side plate 612 along the left-right direction Y and one side of the upper end edge of the rear edge plate 822 along the left-right direction Y with a resin plate 831.

The resin plate 831 is formed to be thinner than the rear plate 612 and the rear edge plate 822, and can bend or extend in the rotational direction around an imaginary axis along the left-right direction Y. Therefore, the support portion 83 allows the tip portion 82t of the pivot plate 820 to pivot in a direction away from or toward the lower end portion of the front plate 711.

The locking portion 84 allows the linking lid portion 82 to be locked to the linking receiving portion 81 when it is closed. The locking portion 84 is composed of a locking piece 841 provided on the tip portion 82t of the pivot plate 820 and a locking ring 842 provided on the lower end portion of the front side plate 711.

The locking piece 841 is formed perpendicular to the pivot plate 820 at the tip portion 82t of the pivot plate 820. When the pivot plate 820 closes the openings 60 and 70, the locking piece 841 is a plate with a rectangular cross section that is short in the front-rear direction X and long in the left-right direction Y, and has a locking claw 84f formed on its front surface (see Figures 9(b) and 11(a)).

The locking ring 842 is formed in a generally rectangular tube shape with a horizontal plate 84h arranged parallel to the front plate 711 at a predetermined distance, and a pair of support plates (reinforcement plates 713 described later) arranged perpendicular to the front plate 711 and parallel to each other at a predetermined distance (see Figures 9(b) and 11(a)). A through hole is formed on the inside of the locking ring 842, penetrating in the vertical direction Z. Therefore, when the locking piece 841 is inserted into the locking ring 842, the locking claw 84f of the locking piece 841 hooks onto the horizontal plate 84h that constitutes the locking ring 842.

The receiving parts 61 and 71 constituting the connected receiving part 81 are connected via connecting plates 811 and 812 extending in the front-rear direction X. The connecting plate 811 is disposed at a position offset toward the center in the left-right direction Y from the end of the left side L of the receiving parts 61 and 71, and the connecting plate 812 is disposed at a position offset toward the center in the left-right direction Y from the end of the right side R of the receiving parts 61 and 71. Therefore, a gap space Sd recessed toward the center in the left-right direction Y when viewed from the upper side U is formed between the receiving parts 61 and 71 (see FIG. 9(b), FIG. 15, and FIG. 19).

The front plate 711 of the receiving portion 71 constituting the housing connecting portion 7 is provided with a reinforcing plate 713 protruding toward the front side F. To explain in detail, the end of the left side L of the front plate 711 is provided with two reinforcing plates 713 protruding toward the front side F, and the end of the right side R of the front plate 711 is also provided with two reinforcing plates 713 protruding toward the front side F. These reinforcing plates 713 are formed from the upper end portion to the lower end portion of the front plate 711 along the vertical direction Z. Therefore, when a separate additional fixing device main body 5 is further connected to the additional fixing device main body 5 connected to the basic fixing device main body 2, the reinforcing plate 713 is disposed inside the gap space Sd described above (see FIG. 19).

In this regard, the height (length in the front-rear direction X) of the reinforcing plate 713 may be appropriately set so that the leading edge of the reinforcing plate 713 comes into line contact with the rear side plate 712. In this way, it is possible to prevent the harness fixing device 1 from bending due to the weight of the additional fixing device main body 5 or the weight of the exterior harness WH. In addition, by appropriately setting the positions of a pair of reinforcing plates 713 provided at the center side in the left-right direction Y among the four reinforcing plates 713 provided on the front side plate 711, these reinforcing plates 713 may abut against the connecting plates 811, 812 and even sandwich the connecting plates 811, 812. In this way, it is possible to prevent the harness fixing device 1 from bending due to the weight of the additional fixing device main body 5 or the weight of the exterior harness WH.

In this way, the additional fixing device main body 5 has a housing connection portion 7 that houses the holding portion 3, which is part of the basic fixing device main body 2. Therefore, the additional fixing device main body 5 can be connected to the basic fixing device main body 2 (see Figures 13 to 15). In this case, the harness fixing device 1 can hold two exterior-equipped harnesses WH.

In addition, since the holding portion 3, which is part of the basic fixing device main body 2, and the holding portion 6, which is part of the additional fixing device main body 5, are the same size and shape, the housing connection portion 7 can also house the holding portion 6. Therefore, a separate additional fixing device main body 5 can be connected to the additional fixing device main body 5 (see Figures 18 and 19). In this case, the harness fixing device 1 can hold three exterior-equipped harnesses WH. And, by connecting a further separate additional fixing device main body 5, the harness fixing device 1 can also hold three or more exterior-equipped harnesses WH.

The holding portion 3 of the basic fixing device main body 2 and the holding portion 6 of the additional fixing device main body 5 have an outer shape formed with a square cross section. That is, the cross section perpendicular to the left-right direction Y is formed with a square cross section. On the other hand, the housing connecting portion 7 of the additional fixing device main body 5 has an inner shape formed with a square cross section. That is, the cross section perpendicular to the left-right direction Y is formed with a square cross section. Therefore, when the holding portions 3 and 6 are housed in the housing connecting portion 7, their four faces are in contact with each other.

To be more specific, when the holding unit 3 is housed in the housing connection unit 7, the upper plate 310, front plate 311, rear plate 312, and pivot plate 320 of the holding unit 3 are in contact with the upper plate 710, front plate 711, rear plate 712, and pivot plate 820 of the housing connection unit 7. Also, when the holding unit 6 is housed in the housing connection unit 7, the upper plate 610, front plate 611, rear plate 612, and pivot plate 820 of the holding unit 6 are in contact with the upper plate 710, front plate 711, rear plate 712, and pivot plate 820 of the housing connection unit 7.

As shown in FIG. 20(a), the harness fixing device 1 has a bolt gripping portion 42 on the fixing portion 4, and the bolt gripping portion 42 can grip the stud bolt B. The harness fixing device 1 according to this embodiment is attached by fitting the bolt gripping portion 42 from the lower side D to the stud bolt B protruding from the chassis frame Cf.

In addition, as shown in FIG. 20(b), the harness fixture 1 has a cassette engagement portion 43 on the fixing portion 4, and can also be engaged with the lock plate P by the cassette engagement portion 43. The harness fixture 1 according to this embodiment is attached by fitting the cassette engagement portion 43 from the upper side U to the lock plate P provided on the connector box Cb.

As described above, the harness fixing device 1 according to this embodiment holds multiple exterior harnesses WH arranged side by side in a cross direction (front-rear direction X) that crosses the longitudinal direction (left-right direction Y) and can be fixed to a chassis frame Cf or the like. It has multiple fixing device bodies provided with holding parts 3, 6 that hold the exterior harnesses WH. The fixing device body has a basic fixing device body 2 provided with a fixing part 4 that can be fixed to a chassis frame Cf or the like in addition to the holding part 3, and an additional fixing device body 5 provided with a holding connection part 7 that connects by holding the holding part 3 of the basic fixing device body 2 or the holding part 6 of the additional fixing device body 5.

According to such a harness fastener 1, the number of armored harnesses WH that can be held can be changed.
More specifically, the harness fastener 1 according to the present invention is capable of holding a plurality of armored harnesses WH arranged side by side in a transverse direction (front-rear direction X) intersecting the longitudinal direction (left-right direction Y) and fastening to a chassis frame Cf or the like, and has a plurality of fastener bodies provided with holding portions 3, 6 for holding the armored harnesses WH. The fastener body has a basic fastener body 2 provided with a fixing portion 4 capable of fastening to the chassis frame Cf or the like in addition to the holding portion 3, and an additional fastener body 5 provided with a holding and connecting portion 7 that connects by holding the holding portion 3 of the basic fastener body 2 or the holding portion 6 of the additional fastener body 5.
According to this configuration, the additional fixing device main body 5 can be connected to the basic fixing device main body 2. Also, a separate additional fixing device main body 5 can be connected to the additional fixing device main body 5 connected to the basic fixing device main body 2. Therefore, when the additional fixing device main body 5 is connected to the basic fixing device main body 2, two exterior harnesses WH can be held. Also, when a separate additional fixing device main body 5 is connected to the additional fixing device main body 5 connected to the basic fixing device main body 2, three exterior harnesses WH can be held. In this way, by preparing the additional fixing device main bodies 5 in a number equal to the number of exterior harnesses WH minus one, in addition to the basic fixing device main body 2, and connecting these, all of the exterior harnesses WH can be held. Therefore, the harness fixing device 1 according to the present invention can change the number of exterior harnesses WH that it holds.

In addition, in the harness fastener 1 according to this embodiment, the holding connection portion 7 is a housing connection portion 7 in which a housing space Sc is formed to house the holding portion 3 of the basic fastener body 2 or the holding portion 6 of the additional fastener body 5. The housing connection portion 7 is configured to house the entire holding portion 3, 6.

With this type of harness fixing device 1, the holding portion 3 of the basic fixing device main body 2 or the holding portion 6 of the additional fixing device main body 5 is accommodated in the accommodating and connecting portion 7 of the additional fixing device main body 5, so the harness fixing device 1 can be made smaller than harness fixing devices that are connected via connecting portions protruding from each fixing device main body 2, 5.

In addition, in the harness fastener 1 according to this embodiment, the outer shape of the holding parts 3 and 6 is formed to have a square cross section, the inner shape of the housing connection part 7 is formed to have a square cross section, and the outer surfaces of the holding parts 3 and 6 and the inner surface of the housing connection part 7 abut on at least two surfaces.

With this harness fixing device 1, the outer surfaces of the holding parts 3 and 6 come into contact with the inner surface of the housing connecting part 7 on at least two surfaces, so the additional fixing device main body 5 does not rotate around this connecting part. This prevents the harness fixing device 1 from bending due to the weight of the additional fixing device main body 5 or the weight of the exterior-mounted harness WH.

In addition, in the harness fixing device 1 according to this embodiment, the holding portions 3 and 6 are provided with ribs 31r, 32r, 61r, and 62r at their portions extending in the longitudinal direction (left-right direction Y) that fit into recesses formed on the outer circumferential surface of the corrugated tube C that is sheathed on the sheathed harness WH.

With this type of harness fixing device 1, the ribs 31r, 32r, 61r, and 62r provided on the holding portions 3 and 6 fit into the recesses of the corrugated tube C that is sheathed to the wire harness W, so that even if the sheathed harness WH is pushed or pulled in the longitudinal direction (left-right direction Y), the holding position of the sheathed harness WH in the longitudinal direction (left-right direction Y) can be prevented from shifting.

In addition, in the harness fastener 1 according to this embodiment, the housing connection portion 7 is provided with ribs 71r, 72r that fit into recesses formed on the outer circumferential surface of the corrugated tube C that is fitted to the wire harness W, at a portion that extends in the longitudinal direction (left-right direction Y) beyond the housed holding portions 3, 6.

With this type of harness fixing device 1, the ribs 71r, 72r provided on the housing connection portion 7 fit into the recesses of the corrugated tube C that is sheathed to the wire harness W, so that even if the sheathed harness WH is pushed or pulled in the longitudinal direction (left-right direction Y), the holding position of the sheathed harness WH in the longitudinal direction (left-right direction Y) can be prevented from shifting.

In addition, in the harness fastener 1 according to this embodiment, in the additional fastener main body 5, the holding portion 6 has a receiving portion 61 that holds the exterior-mounted harness WH and a lid portion 62 that closes the opening portion 60 of the receiving portion 61, and the housing connecting portion 7 has a receiving portion 71 that houses the holding portion 3 of the basic fastener main body 2 or the holding portion 6 of the additional fastener main body 5 and a lid portion 72 that closes the opening portion 70 of the receiving portion 71, and the lid portion 62 and the lid portion 72 are connected together to form a connected lid portion 82.

With this harness fastener 1, the openings 60, 70 of the receiving parts 61, 71 can be opened simultaneously by operating the connecting lid 82. Conversely, the openings 60, 70 of the receiving parts 61, 71 can also be closed simultaneously. This makes it easier to fit the exterior harness WH, the holding part 3 of the basic fastener main body 2, or the holding part 6 of the additional fastener main body 5 into the receiving parts 61, 71. In addition, the fitting direction of the exterior harness WH is the same as the fitting direction of the holding part 3 of the basic fastener main body 2 or the holding part 6 of the additional fastener main body 5, making these fitting operations easier.

Further, in the harness fastener 1 according to this embodiment, a support portion 83 is provided that supports the connecting lid portion 82 so that it can pivot freely relative to the connecting receiving portion 81 .
According to such a harness fastener 1, the connecting lid portion 82 can be opened and closed while the connecting receiving portion 81 and the connecting lid portion 82 are connected to each other. Therefore, it is possible to prevent the connecting receiving portion 81 and the connecting lid portion 82 from being separated from each other during the operation of fitting the exterior-mounted harness WH, the holding portion 3 of the basic fastener main body 2, or the holding portion 6 of the additional fastener main body 5 into the connecting receiving portion 81. It is also possible to reduce the number of parts.

Further, in the harness fastener 1 according to this embodiment, a locking portion 84 is provided that locks the connecting lid portion 82 to the connecting receiving portion 81 in a closed state.
According to such a harness fastener 1, the connecting lid portion 82 can be locked simply by closing the connecting lid portion 82 on the connecting receiving portion 81. Therefore, the connecting lid portion 82 can be quickly kept in a closed state during an operation such as fitting the exterior-mounted harness WH, the holding portion 3 of the basic fastener main body 2, or the holding portion 6 of the additional fastener main body 5 into the connecting receiving portion 81. It is also possible to release the lock and lock it again.
