Description

The present invention relates to a protector and an armored harness provided with the protector.

Conventionally, corrugates and protectors, which are exterior parts of wire harnesses, have been known. A corrugate is a flexible exterior component that covers a wire harness, and protects the wire harness from foreign matter and the like. The protector is an exterior component that covers the wire harness and does not have flexibility, and protects the wire harness from foreign objects and the like, and is attached to a body panel or the like to regulate the wiring route.

By the way, Patent Document 1 and Patent Document 2 disclose protectors arranged between two corrugates. Such a protector is connected to both corrugates by closing the lid with the ends of the corrugates housed inside. However, since the width and height dimensions of such a protector are larger than the outer diameter of the corrugate, there is a problem that the cross-sectional shape cannot be avoided to be enlarged, and the protector cannot be installed in a narrow gap.

In addition, in the assembly procedure in which a protector is arranged and connected between the two corrugates after attaching two corrugates to the wire harness, the protector is arranged by appropriately shifting the corrugates attached to the wire harness. However, it is necessary to insert the ends of the corrugates into the protector one by one. Therefore, in such an assembling procedure, there is also a problem that the work of connecting the protector and the corrugate becomes complicated.

SUMMARY OF THE INVENTION The present invention provides a protector and an armored harness equipped with the protector, which can be routed in narrow gaps by reducing the size of the cross-section and can be easily connected to the corrugates arranged on both sides. purpose.

The present invention is a protector arranged between a first corrugate and a second corrugate attached to a wire harness, and communicates with an internal space accommodating the wire harness from one longitudinal side to the other longitudinal side. a protector main body having an opening; a corrugated insertion part inserted into the inside of the first corrugated end on one end side of the protector main body; and the outside of the end of the second corrugated on the other end of the protector main body It is characterized in that a corrugated portion along which it is in contact is provided.

According to the present invention, the reduction in cross-sectional shape enables wiring in narrow gaps, and facilitates connection work with corrugates arranged on both sides.
More specifically, in the protector according to the present invention, a corrugated insertion portion is provided on one end side of the protector main body portion to be inserted into the inside of the end portion of the first corrugated portion. Therefore, only by inserting the corrugated inserting portion inside the end of the first corrugate, the end of the first corrugate can be connected without being accommodated inside the protector main body. Further, in the protector according to the present invention, the corrugated contacting portion is provided on the other end side of the protector main body portion so as to contact the outer side of the end portion of the second corrugate. Therefore, while the first corrugate is connected to one end of the protector main body, the wire harness is pulled, and the outer end of the second corrugate is brought into contact with the corrugated portion (abutting along the corrugated portion). can be connected without housing the end of the second corrugate inside the protector body. Therefore, the width and height dimensions of the protector main body can be kept small, the cross-sectional shape can be made small, and it becomes possible to wire the protector in a narrow gap. Furthermore, it is not necessary to insert the ends of the corrugates one by one into the protector, and the work of connecting the corrugates arranged on both sides is facilitated.

As an aspect of the present invention, the cross section perpendicular to the longitudinal direction of the corrugated insertion portion may have an arc-shaped outer edge that contacts the inner peripheral surface of the first corrugated portion. In addition, the arcuate shape in contact with the inner peripheral surface of the first corrugate means an arcuate shape having the same or substantially the same outer diameter as the inner diameter of the first corrugate.

According to this invention, since the first corrugate is supported in a state in which the outer peripheral surface of the corrugated inserting portion abuts against the inner peripheral surface of the first corrugated portion without gaps, the first corrugated portion extends straight along the longitudinal direction of the corrugated inserting portion. Therefore, the first corrugate does not bend at the connecting portion between the protector and the first corrugate. In addition, since the wiring route of the first corrugate is stabilized, it is possible to prevent the first corrugate from approaching or coming into contact with surrounding structures unintentionally.

Furthermore, since the outer peripheral surface of the corrugated insertion part is in contact with the inner peripheral surface of the first corrugated part without any gap, the first corrugated part is supported. The first corrugated does not fall off. Therefore, in connecting the protector and the first corrugate, it is not necessary to hold the first corrugate by hand to prevent it from falling off. As a result, the work of connecting the protector and the first corrugate is facilitated.

Further, as a mode of the present invention, an end abutment surface with which the end surface of the first corrugate abuts may be provided on the outer peripheral side of the corrugated insertion portion in the connecting portion between the protector main body and the corrugated insertion portion.

According to the present invention, the operator can recognize the insertion margin of the corrugated insertion portion. When the end face of the first corrugate contacts the end contact face, it can be recognized that the first corrugate is properly connected. Therefore, it can be seen at a glance whether the work for connecting the protector and the first corrugate has been properly performed. As a result, the work of connecting the protector and the first corrugate is facilitated.

Further, as a mode of the present invention, a corrugated engaging portion projecting radially outward may be provided on the outer peripheral surface of the corrugated insertion portion. The corrugated locking portion refers to a projecting portion for preventing the first corrugated portion from slipping out of the corrugated inserted portion.

According to this invention, since the corrugated locking portion is caught by the concave and convex shape on the inner peripheral surface of the first corrugate, the first corrugate does not come off even if a load in the tensile direction acts on the first corrugate. Therefore, in connecting the protector and the first corrugate, it is not necessary to hold the first corrugate by hand to prevent it from falling off. As a result, the work of connecting the protector and the first corrugate is facilitated.

Further, as an aspect of the present invention, the vertical cross-section of the corrugated insertion portion with respect to the longitudinal direction may have an inner edge shape that is recessed in the radially outward direction. Note that such a concave shape is a concept that includes various shapes such as a so-called bowl shape, an arc shape, and a polygonal shape.

According to this invention, at least part of the wire harness can be accommodated inside the corrugated insertion portion. Therefore, the wire harness can be held during the work of connecting the protector and the first corrugate. As a result, the work of connecting the protector and the first corrugate is facilitated. In addition, the position of the wire harness can be restricted even after the protector and the first corrugate are connected. As a result, vibration of the wire harness can be suppressed.

Further, as a mode of the present invention, the vertical cross-section of the corrugated portion along the longitudinal direction may have a concave shape in which the inner edge shape is in contact with the outer peripheral surface of the second corrugate. Note that such a concave shape is a concept that includes various shapes such as a so-called bowl shape, an arc shape, and a polygonal shape.

According to this invention, in order to support the second corrugate in a state where the inner peripheral surface of the corrugated contact portion is in contact with the outer peripheral surface of the second corrugate with a surface or a line, the second corrugate is extended along the longitudinal direction of the corrugated contact portion. extends straight. Therefore, the second corrugate does not bend at the connecting portion between the protector and the second corrugate. In addition, since the wiring route of the second corrugate is stabilized, it is possible to prevent the second corrugate from approaching or coming into contact with surrounding structures unintentionally.

Further, as an aspect of the present invention, the cross section perpendicular to the longitudinal direction of the corrugated portion may have an arc shape in which the inner edge shape is in contact with the outer peripheral surface of the second corrugated portion. In addition, the arcuate shape in contact with the outer peripheral surface of the second corrugate means an arcuate shape having an inner diameter that is the same or substantially the same as the outer diameter of the second corrugate.

According to the present invention, the second corrugate is supported in a state in which the inner peripheral surface of the corrugated portion is in contact with the outer peripheral surface of the second corrugated portion without gaps, so that the second corrugated portion is straight along the longitudinal direction of the corrugated portion. Extend. Therefore, the second corrugate does not bend at the connecting portion between the protector and the second corrugate. In addition, since the wiring route of the second corrugate is stabilized, it is possible to prevent the second corrugate from approaching or coming into contact with surrounding structures unintentionally.

Furthermore, the wire harness between the first corrugate and the second corrugate is pushed into the protector body, and the inner peripheral surface of the corrugated contact portion is in contact with the outer peripheral surface of the second corrugate without any gap. Since the second corrugate is supported, the second corrugate does not come off even if the worker releases the hand when connecting the protector and the second corrugate. Therefore, in connecting the protector and the second corrugate, it is not necessary to manually hold the second corrugate so that it does not come off. As a result, the work of connecting the protector and the second corrugate is facilitated.

Further, as an aspect of the present invention, an end contact surface with which the end surface of the second corrugate contacts is provided on the inner peripheral side of the corrugated contact portion in the connecting portion between the protector body portion and the corrugated contact portion. good too.

According to the present invention, the end surface of the second corrugate is pressed against the end contact surface by the elasticity of the second corrugate, so that the second corrugate is stabilized in an upright posture with respect to the end contact surface. Therefore, it can be seen at a glance whether or not the connection work between the protector and the second corrugate has been properly performed. As a result, the work of connecting the protector and the second corrugate is facilitated.

Further, as a mode of the present invention, a corrugated locking portion projecting radially inward may be provided on the inner peripheral surface of the corrugated portion. The corrugated locking portion also refers to a projecting portion for preventing the second corrugated portion from coming off the corrugated portion.

According to this invention, since the corrugated locking portion is hooked on the uneven shape of the outer peripheral surface of the second corrugate, the second corrugate does not come off even if a load in the pulling direction acts on the second corrugate. Therefore, in connecting the protector and the second corrugate, it is not necessary to manually hold the second corrugate so that it does not come off. As a result, the work of connecting the protector and the second corrugate is facilitated.

Further, as an aspect of the present invention, the cross section perpendicular to the longitudinal direction of the corrugated portion has an inner edge shape that is an arc shape that contacts the outer peripheral surface of the second corrugate and extends in a tangential direction from the peripheral end portion of the arc shape. It may have a linear shape or a curved shape having a larger curvature than the arc shape.

According to this invention, the flat plate portion corresponding to the linear portion or the curved plate portion corresponding to the curved portion functions as a guide plate when connecting the second corrugate. Therefore, the second corrugate can be guided to the correct position simply by pushing the second corrugate along the flat plate portion or the curved plate portion of the corrugated portion. As a result, the work of connecting the protector and the second corrugate is facilitated.

Further, as a mode of the present invention, the protector main body is provided with an anchor portion to be inserted into a mounting hole of a body panel, and the inner peripheral surface of the wall portion facing the opening is opposed to the wall portion provided with the anchor portion. A rib may be provided to connect the wall.

According to this invention, the rigidity of the protector main body in the insertion direction of the anchor portion is improved. Therefore, when an operator presses the protector main body to lock the anchor to the body panel, the protector main body can be prevented from being bent and the anchor is incompletely locked.

Further, as an aspect of the present invention, in a pair of wall portions that constitute the opening, the wall portions are shortened in the pushing direction of the wire harness or the wall portions are extended in the anti-pushing direction of the wire harness. An extension may be provided.

According to the present invention, resistance when the wire harness is pushed in is reduced in the portion provided with the shortened portion. Therefore, it becomes easier for the worker to push the wire harness. In addition, the resistance when the wire harness is pulled out increases at the portion where the extension portion is provided. Therefore, it is possible to prevent the wire harness from falling off from the protector even if a load acts on the wire harness in the direction of pulling it out.

Further, the present invention is an armored harness comprising a first corrugate, a second corrugate, and any one of the protectors arranged and connected between the first corrugate and the second corrugate. Characterized by

According to the present invention, since the cross-sectional shape is reduced in size, the cable can be routed through a narrow gap. In addition, since the connecting work with the corrugates arranged on both sides becomes easy, the productivity can be improved.

As shown in FIG.

As shown in FIG. 1, the harness with exterior 100 is responsible for power supply and signal transmission from electrical component to electrical component. The armored harness 100 has a first corrugate 10, a second corrugate 20, and a protector 1 arranged between the first corrugate 10 and the second corrugate 20 as armor parts for protecting the wire harness 30. there is

The first corrugate 10 and the second corrugate 20 are flexible exterior parts that cover the wire harness 30 and protect the wire harness 30 from foreign substances and the like. The first corrugate 10 has a shape in which large-diameter portions 101 and small-diameter portions 102 continue alternately, and the second corrugate 20 also has a shape in which large-diameter portions 201 and small-diameter portions 202 continue alternately.

The protector 1 is an exterior part that does not have flexibility and covers the wire harness 30, and protects the wire harness 30 from foreign objects and the like, and is attached to the body panel 50 and the like to regulate the wiring route. The protector 1 is integrally formed using polypropylene resin and has at least a structure embodying the present invention. The protector 1 will be described in detail below.

As shown in FIGS. 2 to 6, the protector 1 has a protector body portion 2, a corrugated insertion portion 3, a corrugated along-side portion 4, and an anchor portion 5. As shown in FIGS. Therefore, the protector body portion 2 will be described first, and then the corrugated insertion portion 3, the corrugated along-line portion 4, and the anchor portion 5 will be described in order.

The protector main body 2 has an opening 2o that communicates with the internal space S that accommodates the wire harness 30 from one longitudinal side to the other longitudinal side (from the front end to the rear end). The protector main body 2 is provided with a side wall portion 21 that serves as a right side wall portion of the internal space S so as to face the opening 2o. In addition, the protector main body 2 includes an upper wall portion 22 extending leftward from the upper edge of the side wall portion 21 and serving as an upper side wall portion of the internal space S, and an upper wall portion 22 extending leftward from the lower edge of the side wall portion 21 and forming an inner space. A lower wall portion 23 serving as a lower side wall portion of the space S is provided. Therefore, the cross section perpendicular to the longitudinal direction of the protector main body 2 is substantially U-shaped (see FIG. 6(a): XX cross-sectional view).

Further, between the upper wall portion 22 and the lower wall portion 23, the lower wall portion 23 is slightly longer. This enables the wire harness 30 to be pushed in along the lower wall portion 23 . Three ribs 211 connecting the upper wall portion 22 and the lower wall portion 23 are provided in parallel on the inner peripheral surface of the side wall portion 21 of the protector body portion 2 . The lower wall portion 23 of the protector main body 2 has a panel contact portion 231 extending downward and forward, and a panel contact portion 232 extending downward and rearward. and are provided. Functions of these ribs 211 and panel contact portions 231 and 232 will be described later.

Further, the upper wall portion 22 and the lower wall portion 23 of the protector body portion 2 are provided with shortened portions 223 and 233 that are shortened in the pushing direction of the wire harness 30 (see FIG. 3). That is, in a situation where the wire harness 30 is pushed into the internal space S of the protector main body 2, when the direction in which the wire harness 30 is pushed is defined as the pushing direction Df, the upper wall portion 22 is shortened in the pushing direction Df. 223 and a shortened portion 233 in which the lower wall portion 23 is shortened. These shortened portions 223 and 233 are provided in a predetermined range from the front end of the protector main body 2 (range from the front end of the protector main body 2 to the bent portion 2B).

The corrugated insertion portion 3 is provided on one end side (front end portion) of the protector body portion 2 . The corrugated inserting portion 3 is an inserting piece that is inserted inside the end portion of the first corrugated portion 10 , and is provided along the central axis C from the front end portion of the protector body portion 2 . A stepped surface 2 f between the protector main body 2 and the corrugated insertion portion 3 , which corresponds to the connecting portion between the protector main body 2 and the corrugated insertion portion 3 , functions as an end contact surface 31 of the first corrugate 10 . Therefore, when the corrugated insertion portion 3 is inserted inside the end portion of the first corrugated portion 10, the end surface 10f of the first corrugated portion 10 comes into contact with the stepped surface 2f (see FIG. 7).

Further, the cross section perpendicular to the longitudinal direction of the corrugated insertion portion 3 is substantially C-shaped (see FIG. 6(b): YY sectional view). Further, the outer edge shape 3oe at the cross-sectional portion has an arc shape equal to the inner diameter of the first corrugate 10 (the inner diameter of the small diameter portion 102). Therefore, when the corrugated insertion portion 3 is inserted inside the end portion of the first corrugated portion 10, the outer peripheral surface of the corrugated inserted portion 3 and the inner peripheral surface of the first corrugated portion 10 (inner peripheral surface of the small diameter portion 102) abut without a gap. state. The outer peripheral surface of the corrugated insertion portion 3 may be a tapered surface that gradually expands in diameter from the distal end side to the proximal end side. By doing so, it is considered that the contact state is achieved without a gap.

Further, in a cross section perpendicular to the longitudinal direction of the corrugated insertion portion 3, the inner edge shape 3ie in the cross section has an arc shape that is recessed radially outward. Therefore, the wire harness 30 can be held inside the corrugated insertion portion 3 when the corrugated insertion portion 3 is inserted inside the end portion of the first corrugated portion 10 (see FIG. 7). Further, even after the protector 1 and the first corrugate 10 are connected, the position of the wire harness 30 can be restricted by holding it inside the corrugate insertion portion 3 . In addition, in the cross section perpendicular to the longitudinal direction of the corrugated insertion portion 3, the inner edge shape 3ie may be a concave shape depressed radially outward. This is because it is sufficient if the wire harness 30 can be held inside the corrugated insertion portion 3 .

In addition, in the protector 1 according to the present invention, the corrugated insertion portion 3 is provided with the corrugated locking portion 33 . That is, a corrugated engaging portion 33 projecting radially outward is provided on the outer peripheral surface of the distal end portion of the corrugated insertion portion 3 . The corrugated locking portion 33 is accommodated inside the large-diameter portion 101 of the first corrugate 10 in a state in which the corrugated insertion portion 3 is inserted inside the end portion of the first corrugate 10, and the small-diameter portion 102 adjacent to the large-diameter portion 101. caught on. Therefore, even if a load in the tensile direction acts on the first corrugate 10, the first corrugate 10 does not come off. Although the protector 1 has a structure in which only one corrugated locking portion 33 is provided, a plurality of corrugated locking portions 33 may be provided.

The corrugated edge portion 4 is provided on the other end side (rear end portion) of the protector body portion 2 . The corrugated portion 4 is a piece that adheres to the outside of the end portion of the second corrugated portion 20 , and is provided along the central axis C from the rear end portion of the protector body portion 2 . A stepped surface 2r between the protector main body 2 and the corrugated along-contact portion 4, which corresponds to the connecting portion between the protector main body 2 and the corrugated along-connecting portion 4, functions as an end contact surface 41 of the second corrugate 20. Therefore, in a state in which the outer end portion of the second corrugate 20 is in contact with the corrugate contact portion 4, the end surface 20r of the second corrugate 20 comes into contact with the step surface 2r (see FIG. 9).

Further, the cross section perpendicular to the longitudinal direction of the corrugated edge portion 4 is substantially J-shaped (see FIG. 6(c): ZZ sectional view). The inner edge shape 4ie in the cross-sectional portion has an arc shape equal to the outer diameter of the second corrugate 20 (the outer diameter of the large diameter portion 201). Therefore, when the outside of the end portion of the second corrugate 20 is in contact with the corrugated portion 4, a gap is formed between the inner peripheral surface of the corrugated portion 4 and the outer peripheral surface of the second corrugated portion 20 (the outer peripheral surface of the large diameter portion 201). It will be in a state of abutment without any force. The inner peripheral surface of the corrugated portion 4 may be tapered so that the diameter gradually decreases from the distal end side to the proximal end side. By doing so, it is considered that the contact state is achieved without a gap.

Furthermore, in the vertical cross section to the longitudinal direction of the corrugated portion 4, the inner edge shape 4ie in the cross section has an arc shape in contact with the outer peripheral surface of the second corrugate 20 (the outer peripheral surface of the large diameter portion 201), and the arc shape. It has a linear shape extending in the tangential direction from the peripheral end portion 4pe. Therefore, when the outside of the end portion of the second corrugate 20 is brought into contact with the corrugated contact portion 4, simply pushing the second corrugate 20 along the inner surface of the flat plate portion 42 corresponding to this linear portion, The second corrugate 20 can be guided to the correct position. In addition, in the cross section perpendicular to the longitudinal direction of the corrugated portion 4, instead of the linear shape, it may have a curved shape with a larger curvature than the circular arc shape. Even in this case, the second corrugate 20 can be guided to the correct position simply by pushing the second corrugate 20 along the inner surface of the curved plate portion corresponding to the curved portion.

In addition, in the protector 1 according to the present invention, the corrugated portion 4 is provided with the corrugated locking portion 43 . That is, a corrugated locking portion 43 protruding radially inward is provided on the inner peripheral surface of the distal end portion of the corrugated portion 4 . The corrugated locking portion 43 is accommodated outside the small-diameter portion 202 of the second corrugate 20 in a state in which the inner end portion of the second corrugate 20 is in contact with the corrugated contact portion 4, and the large-diameter portion adjacent to the small-diameter portion 202. Get caught in 201. Therefore, even if a load in the tensile direction acts on the second corrugate 20, the second corrugate 20 does not come off. Although the protector 1 has a structure in which only one corrugated locking portion 43 is provided, a plurality of corrugated locking portions 43 may be provided.

The anchor portion 5 has a panel insertion portion 51 inserted into the mounting hole 50h of the body panel 50 and a panel locking portion 52 locked into the mounting hole 50h of the body panel 50 . Note that the panel abutting portions 231 and 232 described above are in a state in which the panel insertion portion 51 is inserted into the mounting hole 50h of the body panel 50 and the panel locking portion 52 is locked into the mounting hole 50h of the body panel 50. It is pressed against the surface of the body panel 50 . With such a structure, the panel abutting portions 231 and 232 always apply a load in the direction away from the body panel 50, so that the protector 1 can be prevented from rattling, and the protector 1 can be stably supported.

When the protector 1 is fixed to the body panel 50 , the worker presses the protector main body 2 to lock the anchor portion 5 to the body panel 50 . That is, the operator presses the upper wall portion 22 of the protector main body 2 downward from above to deform the panel abutting portions 231 and 232 so that the panel locking portion 52 is moved into the mounting hole 50h of the body panel 50. hooked on and locked. At this time, if the protector main body 2 is bent, the panel locking portion 52 cannot be properly hooked to the mounting hole 50h of the body panel 50, and the anchor portion 5 is incompletely locked. Become. Therefore, three ribs 211 are provided on the inner peripheral surface of the side wall portion 21 so that the protector main body portion 2 is not bent.

These ribs 211 are provided along the insertion direction of the anchor portion 5 and connect the lower wall portion 23 provided with the anchor portion 5 and the opposing upper wall portion 22 . Furthermore, the central rib 211 of the three ribs 211 extends straight upward from the central portion of the anchor portion 5, and the remaining two ribs 211 extend upward from near the ends of the anchor portion 5. It is installed straight. In addition, these ribs 211 have a height that is in contact with the outer peripheral surface of the wire harness 30 so as not to apply a load to the wire harness 30 pushed into the internal space S of the protector main body 2 . However, a structure in which the wire harness 30 is held by recessing the middle portion in the vertical direction of these ribs 211 may be employed.

Next, an assembly procedure for arranging and connecting the protector 1 between the first corrugate 10 and the second corrugate 20 will be described with reference to FIGS. 7 to 11. FIG. Here, it is assumed that the first corrugate 10 and the second corrugate 20 are already attached to the wire harness 30 .

As shown in FIG. 7 , the first step is to connect the protector 1 to the first corrugate 10 . In the first step, the wire harness 30 between the first corrugate 10 and the second corrugate 20 is appropriately bent, and the corrugate insertion portion 3 is inserted inside the end portion of the first corrugate 10 . Then, the end contact surface 31 of the protector 1 is brought into contact with the end face 10 f of the first corrugate 10 . At this time, holding the wire harness 30 inside the corrugated insertion portion 3 facilitates the work.

As shown in FIG. 8 , the second step is to push the wire harness 30 into the protector 1 . In the second step, the wire harness 30 between the first corrugate 10 and the second corrugate 20 is stretched and pushed into the internal space S from the front end of the protector main body 2 through the opening 2o. At this time, since the shortened portions 223 and 233 are provided within a predetermined range from the front end portion of the protector main body portion 2, the initial resistance when pushing the wire harness 30 into the internal space S is suppressed, thereby facilitating the work. .

As shown in FIG. 9 , the third step is to connect the second corrugate 20 to the protector 1 . In the third step, while pulling the wire harness 30 between the first corrugate 10 and the second corrugate 20 , the outer end portion of the second corrugate 20 is brought into contact with the corrugate contact portion 4 . Then, the end face 20 r of the second corrugate 20 is brought into contact with the end contact face 41 of the protector 1 . At this time, if the second corrugate 20 is pushed along the flat plate portion 42 of the corrugated portion 4, the work is facilitated.

As shown in FIG. 10 , the fourth step is to fix the protector 1 and the corrugates (first corrugate 10 and second corrugate 20 ) with tape 40 . In the fourth step, the protector main body 2 and the first corrugate 10 are wound and fixed with a continuous tape 40 .
