Description

  The present invention is a protector for a harness for protecting a harness arranged in a vehicle body, and in particular, when an extra long portion of the harness is drawn out from the protector at a collision of the vehicle body or the like, the protector is not broken and can slide The present invention relates to a harness protector that can be used repeatedly by having the above mechanism.

  The structure shown in FIG. 6 is known as a structure of the protector which penetrates and accommodates the conventional harness. FIG. 6A is a perspective view showing a state of being assembled and fixed to the fixing destination. FIG. 6B is a perspective view showing the state of the protector when the fixing destination is moved.

  As shown in FIG. 6A, the harness 100 is installed in a vehicle such as a car, and the protector 101 is assembled and fixed at a predetermined position of the fixing destination 102 of the vehicle in a state where the harness 100 is penetrated and stored. The protector 101 mainly includes a protector body 103 and a protector cover 104 engaged with the protector body 103. The protector main body 103 and the protector cover 104 are molded of an insulating resin material.

  The protector body 103 has a first opening 105 and a second opening 106 in order to store the harness 100 therethrough, and the first opening 105 and the second opening 106 are continuous with the storage space 107, respectively. Then, the first opening 105 widens along the first intersecting direction C orthogonal to the axis of the harness 100, and the opening interval along the second intersecting direction D becomes constant according to the diameter of the harness 100.

  The protector cover 104 is a substantially plate-like member, and is formed to cover the entire upper surface of the protector main body 103 provided with the first opening 105. The protector cover 104 has a cover main body 108, a fractured portion 109, and a slit 110 serving as a boundary between them.

  As shown in FIG. 6B, for example, when the fixed point 102 moves in the direction of arrow A at the time of a collision of the vehicle, the harness 100 moves by the length of the excess length portion 111, and the broken portion of the protector cover 104 109 is pushed by the harness 100 to break. On the other hand, the fixing destination 102 can move by the length of the extra length portion 111 of the harness 100, and if the fixing destination 102 can be moved, damage to the fixing destination 102 can be mitigated (for example, Patent Document 1).

Patent No. 5899588

  The storage space 107 of the protector 101 has an extra length storage space 112 of the harness 100, and accommodates the extra length portion 111 of the harness 100. As described above, while the fixed end 102 moves in the direction of arrow A at the time of a collision of the vehicle, the harness 100 pulls out the extra length portion 111 in the direction of arrow B which is the substantially opposite direction. The fractured portion 109 of the cover 104 is fractured.

  In the protector 101, the breakage portion 109 of the protector cover 104 is broken upward to pull out the extra length portion 111 of the harness 100, so that after the protector 101 is broken due to the collision of the vehicle, Each time the protector 101 needs to be replaced with a new one, there is a problem that the protector 101 can not be used repeatedly and it is difficult to reduce the part cost.

  Further, at the time of the collision of the vehicle, for example, the fixed position of the electrical component connected to the harness 100 may move and the harness 100 may be pulled due to the vehicle body being crushed and deformed.

However, the harness 100 derived from the protector 101 is not protected by the protector 101. As a result, although the connection state with the electrical component is maintained, the harness 100 may be involved in the crushing deformation of the vehicle body at the time of a collision and may be broken.

  In addition, when assembling the harness 100 to the protector 101, the operator erroneously pulls the harness 100 upward, and the broken portion 109 of the protector cover 104 is broken to replace the protector 101 with a new one. There is a problem that it leads to the up. In particular, the wiring work of the harness 100 and the fixing work of the protector 101 are often performed in a narrow area, and as described above, the possibility of breaking the protector 101 during the assembling work is increased.

  Further, although the extra length portion 111 of the harness 100 has a structure to be stored in the extra length storage space 112, the structure is such that the harness 100 is not fixed to the protector 101. As the harness 100 is pulled, there is a fear that the excess length portion 111 of the harness 100 is not stored in the excess storage space 112 at the time of a collision of the vehicle, and the harness 100 can not be derived. is there.

In FIG. 2A, an intermediate portion in the front-rear direction (longitudinal direction) of the main body portion 11B of the upper housing 11 and the lower housing 12 is omitted.

  FIG. 2A shows a state in which the main body portion 11B and the fitting panel portion 13 of the upper housing 11 are locked to the lower housing 12. As illustrated, the harness 21 indicated by a dotted line is stored in the storage space 22 formed by the main body portion 11B of the upper housing 11 and the lower housing 12 in a state of having an extra length. Then, one end of the extra length harness 21 is drawn out from the opening 11E of the main body 11B of the upper housing 11 to the outside, and the other end of the extra length harness 21 is the opening of the lower housing 12 It derives from the part 12G to the outside.

  The harness support 13 </ b> A is fitted to the opening 11 </ b> E of the main body 11 </ b> B of the upper housing 11 on the side 11 </ b> A side of the upper housing 11. Then, a semicircular opening that is a part of the opening 11E is formed in the main body 11B, and the harness 21 has a semicircular recess 13E (see FIG. 2) on the upper end side of the opening and the harness support 13A. 1 (C))). The shape of the opening 11E is not limited to a circle, as long as the shape allows the harness 21 to be derived. For example, a square opening may be used.

  When the harness support 13A of the fitting panel 13 is fitted to the opening 11E of the main body 11B of the upper housing 11, the harness fixing part 13C of the fitting panel 13 is positioned forward of the opening 11E. doing. The harness 21 is fixed to the harness fixing portion 13C by a mounting member 23 such as a vinyl tape.

  The locking portion 13D of the fitting panel portion 13 is formed at the tip of the lower end side connection portion 13B which is formed to be substantially parallel to the harness fixing portion 13C. The locking portion 13D has an anchor shape that protrudes on the lower side of the connecting portion 13B. Then, in a state where the locking portion 13D is inserted into the locking opening 12D of the lower housing 12, the locking portion 13D is hooked on the side surface 12C of the lower housing 12 that constitutes the locking opening 12D. Thus, the state in which the upper housing 11 is locked to the lower housing 12 is realized.

  As described above, in the state where the upper housing 11 is locked to the lower housing 12, the harness 21 drawn from the opening 11E is fixed to the harness fixing portion 13C. And the harness 21 is derived | led-out to a substantially orthogonal direction with respect to side 11A of main-body part 11B. On the other hand, the connecting portion 13B in which the locking portion 13D is formed is disposed in a direction substantially orthogonal to the side surface 12C of the lower housing 12. With this structure, the locking portion 13D can be retained on the side surface 12C of the lower housing 12 to maintain the locked state.

  On the other hand, on the side surface 12E side of the lower housing 12, the harness 21 drawn out from the opening 12G is fixed to the protrusion fixing portion 12F by the mounting member 24 such as a vinyl tape. Note that, as shown in FIG. 1B, the shape of the opening 12G is not limited to a square, as long as the harness 21 can be derived, for example, a circular shape having the same shape as the harness 21. It may be an opening.

  FIGS. 2B and 2C show a state in which the main body portion 11B of the upper housing 11 and the fitting panel portion 13 are released from the lower housing 12 by the locking. As described above, since the fitting panel portion 13 is in a state of being fitted into the main body portion 11B of the upper housing 11, the harness fixing portion 13C of the fitting panel portion 13 can be obtained by keeping the harness 21 strongly pulled. With respect to the main body portion 11B of the upper housing 11, it moves slightly forward and downward.

  At this time, as indicated by a circle 25, the connecting portion 13 B of the fitting panel portion 13 is bent in an arcuate shape because the harness supporting portion 13 A is fitted to the opening 11 E. The locking opening 12D of the lower housing 12 has a space above the connecting portion 13B, and interlocking with the bending operation of the fitting panel portion 13, the connecting portion 13B including the locking portion 13D. Move upwards.

  As a result, as shown in FIG. 2C, the above-mentioned locked state in which the locking portion 13D is caught on the side surface 12C of the lower housing 12 is cancelled, and as shown by the arrow 26, the fitting panel portion 13 is The main body 11 B of the upper housing 11 and the lower housing 12 are pulled out. Then, in conjunction with the pulling operation of the harness 21, the main body 11 </ b> B of the upper housing 11 starts sliding movement with respect to the lower housing 12. Incidentally, although a part of the connecting portion 13B of the fitting panel 13 bends in conjunction with the pulling operation of the harness 21, the fitting panel 13 is molded of a thermoplastic resin to have the above-mentioned locked state. By returning to the original state after being eliminated, it is difficult to be damaged and repeated use becomes possible.

  FIG. 3A is a cross-sectional view for explaining a locked state of the protector 10 of the present embodiment, and shows a cross-section in the direction of line A-A shown in FIG. Drawing 3 (B) is a sectional view explaining the slide movement state of protector 10 of this embodiment, and shows the section of the AA line direction shown in Drawing 1 (A).

  As shown in FIG. 3A, in the state where the upper housing 11 is locked to the lower housing 12, a part of the harness 21 has an extra length, and a storage space 22 of the protector 10 is obtained. It is housed inside. Then, one end side of the harness 21 is fixed to the harness fixing portion 13C of the fitting panel portion 13 fitted to the main body portion 11B of the upper housing 11 via the mounting member 23. Further, the other end side of the harness 21 is fixed to the protrusion fixing portion 12F of the lower housing 12 via the mounting member 24.

  With this structure, the harness 21 has an extra length, is stored in the storage space 22 during assembly work of the protector 10 or the like, and after being secured to the harness fixing portion 13C and the protrusion fixing portion 12F, the excess length portion However, it is possible to maintain the state of being securely stored in the storage space 22 of the protector 10.

  As shown in FIG. 3B, the harness 21 is pulled to the front of the protector 10, and as described above, in the locking portion 13D of the fitting panel portion 13, the locking opening 12D of the lower housing 12 The main body portion 11B of the upper housing 11 starts sliding movement forward with respect to the lower housing 12.

  At this time, the storage space 22 is constituted by a region in which the main body portion 11B of the upper housing 11 and the lower housing 12 are opposed and combined, but as indicated by the arrow 31, the main body of the upper housing 11 The sliding movement of the portion 11B narrows the space of the storage space 22. In other words, the extra long portion of the harness 21 is derived from the storage space 22 by the harness 21 being pulled forward. And the harness 21 of the part derived | led-out is the state by which the upper direction was protected only by the main-body part 11B of the upper housing | casing 11. FIG. Although details will be described later, since the lower housing 12 is clip fixed or bolted to the vehicle body frame 41 (see FIG. 4), the lower housing 12 is moved from the fixed position to the vehicle body frame 41 do not do.

  As a result, the width in the front-rear direction (longitudinal direction) of the storage space 22 of the protector 10 shown by the arrow 31 is narrowed, but the remaining portion of the harness 21 drawn from the storage space 22 continues to be the main body of the upper housing 11 It is a state where the upper part is protected only by 11B, and even when it is involved in the crushing deformation of the vehicle body frame 41 at the time of a collision, a structure in which the extra length part of the derived harness 21 is difficult to cut is realized.

  Although not shown, when the length of the extra length portion of the harness 21 is longer than the width in the front-rear direction (longitudinal direction) of the main body portion 11B of the upper housing 11, the main body portion of the upper housing 11 11B may be detached from the lower housing 12. On the other hand, when the length of the extra length portion of the harness 21 is shorter than the width in the front-rear direction (longitudinal direction) of the main body portion 11B of the upper housing 11, a part of the main body portion 11B of the upper housing 11 is Maintain the state combined with the lower housing 12. That is, the main body 11 </ b> B of the upper case 11 can slide as described above within the length of the extra length portion of the harness 21.

  FIG. 4 is a plan view illustrating a state in which the protector 10 and the harness 21 of the present embodiment are fixed to the vehicle body frame 41. FIG. 5A and FIG. 5B are plan views for explaining the operation state of the protector 10 of the present embodiment, and showing an arrangement region of the protector 10 shown in FIG. 4 in an enlarged manner. In FIG. 5B, the vehicle body frame 41 is illustrated in a state where the vehicle body frame 41 is not crushed and deformed for convenience of explanation.

  As shown in FIG. 4A, the harness 21 is, for example, a wire that electrically connects an electronic control unit (ECU) that executes various calculations for vehicle control and the air bag sensor 42. The airbag sensor 42 is mounted on the radiator support panel 43 at a position closest to the front of the body frame 41 in order to measure the impact at the time of a vehicle collision in detail and to inflate and deploy a desired airbag (not shown) appropriately. Be The harness 21 is routed, for example, along the front side members 44 of the vehicle body frame 41, and the protector 10 is fixed to the front side members 44 near the radiator support panel 43.

  The lower housing 12 of the protector 10 is clip fixed or bolted to a mounting hole (not shown) of the vehicle body frame 41, and the lower housing 12 is also mounted on the lower housing 12 when the harness 21 is pulled to the front side of the protector 10. The body 12 is a structure that does not move. On the other hand, when the harness 21 is pulled to the front side of the protector 10, the upper housing 11 is lower because the upper housing 11 is locked to the lower housing 12. It slides relative to the housing 12.

  FIG. 5A shows the installation state of the protector 10 in the normal operation state. As illustrated, the protector 10 is fixed to the front side member 44 near the radiator support panel 43. And the harness 21 derived | led-out from the upper housing | casing 11 of the protector 10 is connected with the airbag sensor 42 via a connector member (not shown). With this structure, the signal from the air bag sensor 42 is sent to the electronic control unit.

  FIG. 5B shows, for example, the installation state of the protector 10 when the vehicle has caused a frontal collision. As illustrated, when the vehicle causes a frontal collision, the vehicle body frame 41 such as the radiator support panel 43 is crushed and deformed to absorb the impact energy at the time of the collision and reduce the damage to the accident vehicle or the pedestrian etc. Let With this structure, the air bag sensor 42 also moves to the rear side of the vehicle in conjunction with the above-mentioned crushing deformation.

  As described above, the harness 21 is connected to the airbag sensor 42 via the connector member, and the harness 21 is also pulled by the airbag sensor 42. As described with reference to FIGS. 1 to 3, when the harness 21 is pulled, the locked state of the protector 10 is cancelled, and the main body portion 11B of the upper housing 11 is on the front side with respect to the lower housing 12. Start slide movement.

  With this structure, the harness 21 follows while maintaining the connection with the air bag sensor 42 for a fixed period of time after the frontal collision of the vehicle. The signal can be reliably transmitted to the electronic control unit to properly inflate and deploy the desired airbag. That is, the protector 10 maintains the state in which the harness 21 is connected to the air bag sensor 42 at least until the electric signal measured by the air bag sensor 42 is transmitted to the electronic control unit.

  Furthermore, at the time of the frontal collision, when the protector 10 is not involved in the crushing deformation and is not broken, the upper case 11 is assembled to the lower case 12 again to use as the protector 10 can do. Similarly, even when the worker erroneously cancels the locking state of the protector 10 at the time of assembling the protector 10, the locking portion 13D of the fitting panel portion 13 of the upper housing 11 is made of the lower housing 12 again. It can be inserted into the locking opening 12D to be in the locked state.
