Description

  The present invention relates to a protector for housing and protecting a wire harness (electric wire), and more specifically, guides an electric wire connected to an electrical component in a predetermined direction by a main body portion and a cover portion connected by a hinge. It is related with the improvement of the protector to be derived to the outside.

  A vehicle such as an automobile is equipped with various electrical components, and in order to electrically connect them to each other, a large number of electric wires pass through a narrow space in the vehicle in some places. It is routed while being bent. In order to arrange and route the electric wires derived from each electric component and prevent damage to the electric wires due to interference with other components and externally acting force, a protector is generally attached to the electric wires. In other words, the protector has a guide function for guiding the electric wire along a predetermined path together with a protection function for protecting the electric wire from the outside.

As an example of such a protector, a thin hinge is integrally formed between two plate portions of the cover portion, and the bent routing path in the protector body is formed by the cover portion bent at the hinge. A protector that is covered is known (see Patent Document 1).
Japanese Patent Laid-Open No. 3-84212 (page 2, FIG. 1)

  Another example of such a protector is shown in FIGS. As shown in part of FIG. 7 and FIG. 8, the protector 1 includes a body portion 4 and a cover portion 5 that are integrally formed with and connected to the hinge 3. The rotation center axis C of the hinge 3 is arranged in a direction intersecting with the arrangement direction (A direction) of the electric wire 2 accommodated and guided in the arrangement path provided in the main body 4. The protector 1 bends the electric wire 2 accommodated in the accommodating chamber of the main body portion 4 by approximately 90 ° at the opening portion 6, then closes the cover portion 5 and engages the locking hole 8 with the locking claw portion 9. Cover the opening 6. Thus, the electric wire 2 is covered and wired while being bent in a predetermined direction.

  Another example of such a protector is shown in FIG. As shown in part of FIG. 9, the protector 10 rotates in a direction that intersects with the wiring direction (A direction) of the electric wire 2 housed and guided in the wiring path provided in the main body 14. A hinge 13 having a central axis C, a main body portion 14 and a cover portion 15 are integrally formed. A locking hole 18 is provided at one end of the main body portion 14 on the opening 16 side, and engages with a locking claw portion 19 formed in the cover portion 15 so as to cover the opening portion 16. The cover portion 15 has a guide portion 15a having a substantially L-shaped cross section that extends to the downstream side in the wiring direction of the electric wire 2 (upward in FIG. 9), and the bent electric wire 2 when the cover portion 15 is closed. Comes into contact with the inner surface of the wire 2 and guides the electric wire 2 for a longer distance to reliably lead it out in a predetermined direction.

  Since the wired electric wire has rigidity, when the electric wire is bent, for example, by 90 °, an elastic restoring force is applied to return to the original state, that is, the straight state. The elastic restoring force of an electric wire generally increases in proportion to the thickness, number, bending angle, etc. of the electric wire. For this reason, the bent electric wire comes into contact with the inner surface of the cover portion of the protector disclosed in Patent Document 1, and thereby a force in a direction to open the cover portion always acts on the cover portion. Since the pivot center axis of the hinge is provided in a direction crossing the wiring direction of the electric wire, the elastic restoring force of the electric wire rotates the cover portion around the pivot central axis of the hinge (that is, the cover portion is Acts in the direction of opening. In other words, the elastic restoring force of the electric wire is received only by the locking protrusion and the locking piece with which the locking protrusion is engaged. Therefore, the pressing by the elastic restoring force of the electric wire and the vibration of the vehicle such as an automobile are also applied, the engagement of the locking protrusion and the locking piece is released, and the cover part is opened. As a result, the electric wire falls off from the protector and falls apart. Is likely to be. Moreover, if the cover part is opened, the electric wire may be damaged.

  Further, the hinges 3 and 13 of the protector 1 and the protector 10 shown in FIG. 7 to FIG. 9 are electric wires that are guided by being accommodated in a routing route having their rotation center axes C provided in the main body portions 4 and 14. 2, the elastic restoring force of the electric wire 2 is provided with the locking holes 8 and 18 and the locking claws 9 and 19 through the cover parts 5 and 15. Act on. Therefore, there is a high possibility that the engagement between the locking holes 8 and 18 and the locking claw portions 9 and 19 is released due to the addition of the vibration due to the elastic restoring force of the electric wire 2 and the vibration of the vehicle such as an automobile.

  By the way, when the protector 1 and the protector 10 are molded, the rotation center axis C of the hinges 3 and 13 is arranged in parallel with the opening direction of the molding die (that is, the moving direction of the movable die with respect to the fixed die). Therefore, there is a tendency that the thickness of the hinges 3 and 13 is increased due to the provision of the draft and the moldability is deteriorated.

  Further, the protector 10 is provided with a guide portion 15a having a substantially L-shaped cross section with the cover portion 15 extending downstream in the wiring direction of the electric wire 2, so that the depth direction of the molding die (in FIG. (Direction) becomes large, and much cost is required to manufacture the mold. Further, since the guide portion 15a is arranged in parallel with the opening direction of the molding die, the guide portion 15a is difficult to be removed from the molding die, and the moldability tends to deteriorate.

  This invention is made | formed in view of the said situation, The objective is to provide the protector which can prevent reliably open | release of the cover part by the elastic restoring force of an electric wire.

In order to achieve the above-described object, the protector according to the present invention is characterized by the following (1), (2), (3), and (4).
(1) An electric wire housing chamber that can accommodate a plurality of electric wires, and the electric wire in which the guide direction in the electric wire housing chamber is determined along the electric wire housing chamber is led out from the electric wire housing chamber while being bent.

Further comprising
The locking plate portion enters the locking groove when the cover portion is rotated about the hinge as a rotation center axis and covers the opening of the main body.

According to the protector having the above configuration (1), the electric wire accommodated in the electric wire accommodating chamber is bent and led out from the opening, and the cover connected to the main body by the hinge is rotated to guide the electric wire. The ridge provided in the direction intersecting with the slit and the slit are engaged. Thereby, a cover part prevents that an electric wire remove | deviates from the opening part in the radial direction, and covers the opening part of a main-body part. Therefore, the cover part for guiding the electric wire is provided in the direction intersecting with the guide direction of the electric wire and the hinge having the rotation center axis along the direction intersecting with the routing direction which is the electric wire outlet direction. Supported by ridges and slits. Even if the bent wire comes into contact with the inner surface of the cover and the elastic restoring force of the wire acts on the cover, the elastic restoring force of the wire acts on the hinges, ridges and slits at right angles to open the cover. It does not work effectively as a force in the direction of Thereby, the electric wire routed to the vehicle or the like can be reliably routed along the predetermined routing route. Further, since the opening is covered with the cover, entry of foreign matter such as water from the outside can be prevented.

The protector 100 is configured as described above, and the assembly procedure of the protector 100 will be described with reference to FIGS. 5 and 6.
As shown in FIG. 5B, while the tongue-like elastic locking piece 23f provided in the storage chamber 35 is elastically deformed, the relay connection terminal 51, which is an example of an electrical component, is inserted into the storage chamber 35, and the tongue It engages with the step portion of the elastic locking piece 23 f and is accommodated in the accommodation chamber 35 and fixed. Next, a male connection portion (not shown) of the relay 53 is inserted into a female connection portion (not shown) of the relay connection terminal 51 to be electrically connected. At this time, many electric wires 29 led out from the relay connection terminal 51 are bundled along the longitudinal direction of the protector body 23 below the protector body 23. In the embodiment shown in FIG. 5, an example in which five electrical components (relay connection terminal 51 and relay 53) are accommodated in the protector body 23 is shown, but the number of electrical components 51 is arbitrary and limited. Not.

  While a large number of bundled electric wires 29 are accommodated and guided in the electric wire accommodating chamber 38 of the lower cover 25, the pair of locking projections 23h of the protector main body 23 are inserted into the fitting holes 37g of the lower cover 25, and the protector main body 23 is inserted. And the relative position of the lower cover 25 are determined. Further, the V-shaped elastic piece portion 23j of the protector main body 23 is inserted into the groove portion 37h of the lower cover 25, and the elastic piece of the V-shaped elastic piece portion 23j is elastically deformed along the vertical wall 23d to thereby form the V-shaped elastic piece portion 23j. The stepped portion and the locking projection 37s of the lower cover 25 are engaged. At this time, the horizontal surface of the locking projection 23n provided on the protector main body 23 and the lower surface of the connecting portion 37f provided on the main body 37 are engaged, and the protector main body 23 and the lower cover 25 are coupled. In this state, the numerous electric wires 29 bundled and accommodated in the electric wire accommodating chamber 38 protrude straight from the opening 43 of the lower cover 25 (in other words, the longitudinal direction of the lower cover 25).

  Next, a number of electric wires 29 protruding in the lateral direction from the opening 43 are bent substantially 90 ° downward, and the cover lead 39 is opened (see FIG. 1C). 45, after being led downward, as shown in FIGS. 3 and 5 (c), the cover 39 is rotated approximately 180 ° in the direction of arrow D about the rotation center axis C of the hinge 41. Let As a result, the locking plate portion 39e of the cover portion 39 is fitted into the locking groove 49 of the main body portion 37, the protrusion 37k of the main body portion 37 is fitted into the slit 47 of the cover portion 39, and The claw portion 39d is inserted into the locking claw receiving portion 37p, the horizontal surface of the locking claw portion 39d is engaged with the upper surface of the plate-like connecting portion 37n of the locking claw receiving portion 37p, and the cover portion 39 is assembled to the main body portion 37. .

  Then, as shown in FIG. 6, the triangular protrusion 23 g of the protector body 23 is inserted into the locking hole 31 of the upper cover 21 while the upper cover 21 is placed on the protector body 23 to cover the relay connection terminal 51 and the relay 53. Then, the lower surface of the connecting portion 21c and the horizontal surface of the triangular protrusion 23g are engaged to assemble the upper cover 21 to the protector body 23, and the assembling of the protector 100 is completed. As a result, the large number of electric wires 29 led out from the lower surface of the protector body 23 are accommodated and guided in the electric wire accommodating chamber 38, further guided by the inner surface of the cover portion 39, bent downward, and led out.

  At this time, the bundle of electric wires 29 bent downward by approximately 90 ° and led downward from the electric wire outlet hole 45 of the lower cover 25 presses the inner surface of the cover portion 39 by the elastic restoring force of the electric wires 29. However, one end of the cover portion 39 rotates in the guiding direction (arrow A direction) of the electric wire 29 guided by the electric wire accommodating chamber 38, in other words, in a direction parallel to the direction in which the elastic restoring force of the bent electric wire 29 acts. It is connected to the main body portion 37 by a hinge 41 having a moving center axis C set, and the other end of the cover portion 39 is set in a direction perpendicular to the guide direction (arrow A direction) of the wire 29 guided by the wire housing chamber 38. Since the engaging groove 49 and the engaging plate portion 39e are engaged, and the slit 47 and the protrusion 37k set in the same direction are engaged with the main body portion 37, the cover The elastic restoring force of the electric wire 29 acting on the part 39 acts on the hinge 41, the locking groove 49 and the locking plate part 39e, and the slit 47 and the protrusion 37k in a direction perpendicular to the hinge 41. Therefore, the elastic restoring force of the electric wire 29 is received by being shared by these, and does not act effectively as a force in the direction of opening the cover 39. In addition, since the main body portion 37 and the cover portion 39 are connected by engagement of the locking claw portion 39d and the locking claw receiving portion 37p, the connection between the main body portion 37 and the cover portion 39 is further strengthened. Has been.

  Further, the main body portion 37 and the cover portion 39 are arranged parallel to each other with their side surfaces adjacent to each other, and along the longitudinal direction of the main body portion 37 (in other words, the electric wires guided by the electric wire housing chamber 38). 29 (in parallel with the guide direction of 29), it is arranged and molded in a state of being rotated 180 ° about the hinge 41 with the rotation center axis C set (that is, upside down with respect to each other). The length of the protector 100 (the length in the left-right direction in FIG. 2) can be shortened compared to a conventional protector in which the pivot center axis C of the hinge is provided in a direction perpendicular to the longitudinal direction of the main body portion 37. . Thereby, the protector 100 can be arranged in a narrow space. Therefore, the protector 100 of the present invention is suitable for use in routing in a device having a narrow routing space such as a vehicle.

  According to the protector 100 of this embodiment, the electric wire 29 accommodated in the electric wire accommodating chamber 38 is bent and led out from the opening 43, and the cover portion 39 connected to the main body portion 37 is rotated by the hinge 41. The protrusion 37k provided in the direction crossing the guide direction of the electric wire 29 and the slit 47 are engaged. Thereby, the cover part 39 prevents the electric wire 29 from coming off from the opening part 43 in the radial direction and covers the opening part 43 of the main body part 37. Therefore, the cover portion 39 that guides the electric wire 29 is supported by the hinge 41 and the protrusions 37k and the slits 47 that are provided in a direction crossing the guide direction of the electric wire 29 and engage with each other. Thereby, even if the bent electric wire 29 abuts against the inner surface of the cover portion 39 and the elastic restoring force of the electric wire 29 acts on the cover portion 39, the elastic restoring force of the electric wire 29 is the hinge 41, the ridge 37k and the slit 47. It does not act effectively as a force in a direction to open the cover portion 39 by acting in a direction perpendicular to the direction. Thereby, the opening of the cover part 39 is prevented and the electric wire 29 routed in the vehicle or the like can be reliably routed along the predetermined routing route. Moreover, since the opening part 43 is covered with the cover part 39, the penetration | invasion of the foreign material from the outside, such as water, can be prevented.

  Further, according to the protector 100 of the present embodiment, the locking claw portion 39d is disposed on one of the main body portion 37 and the cover portion 39, and the locking claw receiving portion is provided on the other of the main body portion 37 and the cover portion 39. 37p is disposed, and when the opening 43 of the main body portion 37 is covered with the cover portion 39, the protrusion 37k and the slit 47 are engaged, and the locking claw portion 39d and the locking claw receiving portion 37p are locked. Let As a result, the force acting on the cover portion 39 is rotated by the engagement of the protrusion 37k and the slit 47 provided in the direction in which the force in the guide direction of the electric wire 29 intersects the guide direction of the electric wire 29, and the cover portion 39. The force in the moving direction is received by the engagement between the locking claw portion 39d and the locking claw receiving portion 37p, and the rotation of the cover portion 39 is reliably prevented. Accordingly, the cover 39 is not opened by the elastic restoring force of the electric wire 29, and the electric wire 29 can be securely bent and routed in a predetermined direction.

  Furthermore, according to the protector 100 of the present embodiment, the hinge 41 is formed between the main body portion 37 and the cover portion 39 so that the rotation center axis C of the hinge 41 extends in parallel with the guide direction of the electric wire 29. Therefore, the hinge 41 arranged in this way has high strength against the elastic restoring force of the electric wire 29. Further, the positional relationship between the main body portion 37 and the cover portion 39 at the time of molding is such that the main body portion 37 and the cover portion 39 are arranged in parallel as compared to when the assembly is completed, and the rotation center axis C of the hinge 41 is the center. It will be in the state expanded 180 degrees. Thereby, in order to guide the electric wire 29 over a long distance, even if the length (height) of the cover portion 39 is increased, the entire length (height) is longer than that of the conventional protector. Never become. That is, the protector can be molded with a small molding die, and the manufacturing cost of the molding die can be reduced.

  Further, according to the protector 100 of the present embodiment, the locking groove 49 is further formed in the vicinity of one of the hinges 41 of the main body portion 37 and the cover portion 39, and the other hinge of the main body portion 37 and the cover portion 39. When a locking plate portion 39e is further formed in the vicinity of 41 and the cover portion 39 is rotated about the rotation center axis C of the hinge 41, the locking plate portion 39e enters the locking groove 49. Accordingly, the cover portion 39 includes the hinge 41, the engagement of the protrusion 37k and the slit 47, the engagement of the locking claw portion 39d and the locking claw receiving portion 37p, the engagement of the locking plate portion 39e and the locking groove 49, Are securely supported at the four locations.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimension, numerical value, form, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  In the above embodiment, the protector is configured by the upper cover, the protector main body, and the lower cover, but instead of using the upper cover and the protector main body, for example, a storage chamber for storing an electrical component is formed in a part of the vehicle body of the vehicle, It is also possible to guide the electric wire by attaching a lower cover to a part of the vehicle body in which the accommodation chamber is formed. That is, the lower cover according to the present invention is a single product, and can be used as a protector without the upper cover and the protector body.

  Further, the protector has been described as covering the electric wire led out from the electrical component accommodated in the protector with the protector and guiding it in a predetermined direction while bending, but the protector is not limited to this and is routed. Needless to say, the present invention can be similarly applied to a case where the middle portion of the electric wire is bent while being covered with a protector and guided in a predetermined direction.
