[0002]

2. Description of the Related Art FIG. 7 shows an example of a mounting structure of a harness protector for a vehicle as an example of a conventional two-article locking structure (see Japanese Utility Model Laid-Open No. 6-42447). FIG. 7 shows a vehicle body cross section (CC cross section) below the front door opening of the automobile shown in FIG.

A harness protector (hereinafter referred to as a protector) 51 is formed of a synthetic resin into a substantially rectangular cylindrical shape or a similar shape, and a wire harness 52 is inserted into an inner space to protect the harness protector from interference with the outside. , FIG.
In the embodiment, when the occupant gets on and off the wire harness 52,
Is protected from being stepped on or kicked. The wire harness 52 is a floor wire harness that is routed along the floor, and is used, for example, to supply power from a battery in an engine room to an auxiliary machine in a rear seat or a trunk room.

[0004] As shown in FIG. 7, the protector 51 has two vertically parallel mounting plates 53, and a vertical rising plate 56 following the side sill 55 of the vehicle body 54 is provided between the two mounting plates 53. It is fixed (locked) to the vehicle body 54 by being sandwiched. A floor carpet 57 is disposed above the protector 51, one end of a scuff plate (kicking plate) 58 is disposed on the carpet 57, and the other end of the scuff plate 58 is fixed to a side sill 55, and one end of the scuff plate 58 is provided via the floor carpet 57. The protector 51 is pressed downward.

[0005]

However, in the above-mentioned conventional structure, the protector 51 is connected to the vehicle body 54.
Is fixed by the mounting plate 53, the fixing force is weak, vibration during vehicle running and the occupant are strong.
And so on, there is a concern that the fixing of the protector 51 may be loosened or the lock may be released.

In order to solve this problem, when the protector is strongly locked to the vehicle body 54 or the scuff plate by means of a lock arm or the like (not shown), the locking arm has a high insertion force at the time of locking, so that the lock arm cannot be inserted. (Latch) Problems such as poor workability, difficulty in releasing the lock after locking, poor maintainability and recyclability of the protector, vehicle body and scuff plate, and even if the lock can be released The base portion of the lock arm made of synthetic resin becomes cloudy and fragile due to re-locking, vibration of the vehicle, or the like, causing a problem that the locking force is extremely reduced.

The locking structure of the two articles is not limited to the locking of the protector and the vehicle body, or the locking of the protector and the plate.
Alternatively, it is appropriately adopted in a synthetic resin clamp and a vehicle body or plate for fixing a wire harness, and a connector bracket and a vehicle body or plate for holding a plurality of connectors.

In view of the above, the present invention can easily and reliably lock two articles, for example, a protector and a plate, and can prevent the locking force of a lock arm from decreasing.

It has a flexible and elastic arm portion 32 inward and obliquely downward. The claw portion 30 has an upper guide inclined surface 30 a and a lower slightly inclined upwardly inclined (inclining direction) locking surface 30.
b and is formed in a substantially triangular shape. Slope 30
a and the locking surface 30b smoothly continue through a short distal end surface 30c that is curved or substantially linear. The locking surface 30b linearly inclines slightly upward from the inner surface of the support portion 29 more than horizontally and continues to the distal end surface 30c. The outer surface of the arm portion 32 is a guide inclined surface 32 a for the claw member 16.

The slightly upwardly inclined engaging surface 30b allows the engaging claw member 16 of the mating plate 12 (FIG. 2) to engage.

The plate thickness of the arm portion 32 is formed smaller than the plate thickness of the support portion 29 of the claw member 14 so that the arm portion 32 is easily bent. Arm part 3
Numeral 2 extends linearly and flatly from the upper end of the vertical support portion 31 obliquely downward at an inclination angle of about 45 °, and a portion 33 on the distal end side (free end side) of the arm portion 32 is an arm inclined portion (reference numeral 32).
), And is bent in a substantially rectangular shape and extends vertically downward and short. The arm tip portion 33 is located below the claw portion 30, has a pressing surface 33 a of the mating plate 12 against the claw member 16 on the outside, and functions as a pressing portion of the plate 12 against the claw member 16.

The arm tip portion 33 can be elastically bent (bent) inward and outward (in the thickness direction) with the bent portion 34 as a fulcrum. The vertical plate-shaped support portion 31 of the arm member 15 is reinforced by a plurality of ribs 35 so as to be inflexible. Arm part 32
Can be bent in the plate thickness direction so as to rotate about the bent portion 36 on the upper end side of the support portion as a fulcrum.

A space 38 is formed between the claw member 14 and the arm member 15 to allow the claw 37 at the tip of the claw member 16 of the counterpart plate 12 to enter, and the space 38 follows the opening 39 in the lower upper wall 11. The opening 39 continues to the inner space (harness accommodation space) 26 of the protector main body 20.

The claw member 16 of the plate 12 is formed of a synthetic resin, and has a claw portion 37 having substantially the same shape as the claw portion 30 of the protector body 20 (hereinafter simply referred to as the protector 4). That is, the claw portion 37 has an upper engagement surface 37b that is slightly inclined obliquely upward and linearly (inclined in the detaching direction), and a lower guide inclined surface 37a. Claw member 14
The angle of inclination between the locking surface 30b and the engaging surface 37b of the claw member 16 is the same, and the locking surface 30b and the engaging surface 37b surely come into contact with each other by surface contact. It has both. The claw member 16 of the plate 12 is formed wider than the claw member 14 of the protector 4. The claw portion 37 continues to the upper vertical plate-shaped support portion 40, and the support portion 40 is reinforced by a plurality of ribs 41 above the claw portion 37.

When the arm 15 is in the free state (the state in which the claw member 16 of the plate 12 is not inserted), the horizontal distance between the tip 30c of the claw 14 of the protector 4 and the pressing surface 33a of the arm tip is equal to the claw of the plate 12. The thickness is set smaller than the thickness of the support portion 40 of the member 16. Pressing surface 33 in free state
“a” may be parallel to the support portion 29 of the claw member 14 or may project slightly inclined toward the support portion 29. As a result, as shown in FIG.
The pressing surface 33 at the tip of the arm is engaged with the claw 30 of the arm.
a elastically presses and urges the claw member 16 of the plate 12 toward the claw member 14 of the protector 4,
, The locking state, i.e., the locking force, is ensured satisfactorily.

When the claw member 16 of the plate 12 is inserted (when the guide inclined surfaces 30a and 37a of the claw portions 14 and 16 are in sliding contact), the claw member 14 of the protector 4 does not bend outward much, and the arm portion 32 is not bent. At this time, the arm portion 32 bends at both the upper bent portion 36 and the lower bent portion 34, so that the stress of the arm portion 32 is dispersed at two places, and the claw member 16 is bent. And the elastic force of the arm portion 32 does not decrease, and the arm portion 32 can be repeatedly (twice or more) inserted by the claw member 16.
The upper bent portion 36 does not become cloudy (not become brittle), the elastic force of the arm portion 32 is always ensured well, and the locking force is guaranteed. The bent portion 34 on the lower side of the arm forms a pressing surface 33a of the arm tip 33, and the pressing surface 33a strongly and stably holds the claw member 16 of the plate 12 with the claw member 1 of the protector 4.
It is needless to say that pressing force is applied to the locking member 4 to secure the locking force.

In the above embodiment, the engaging surface 37b of the pawl 37 of the plate 12 is connected to the pawl 3 of the protector 4.
Although the inclination angle is adjusted to the engagement surface 30b of 0, the engagement angle is not necessarily required. The engagement surface 37b of the claw portion 16 of the plate 12 is formed by a horizontal surface or an obliquely upward inclined surface opposite to FIG. It is also possible to configure. Also in this case, the claw portion 14 of the protector 4 needs to have an obliquely upwardly inclined surface 30b. Alternatively, on the contrary, the engaging surface 37b of the claw portion 37 of the plate 12 may always be an obliquely downwardly inclined surface as shown in FIG. 6, and the locking surface 30b of the claw portion 14 of the protector 4 may be a horizontal surface. However, it is best from the viewpoint of improving the releasability (maintenance and recyclability) that the locking surface 30b and the engagement surface 37b of both claw portions 30, 37 are formed at the same inclination angle as shown in FIG.

Further, the shape of the protector 4 is not limited to the configuration in which the main body 20 and the cover 19 are divided, but the structure of only a gutter-shaped protector main body (not shown), the structure of the main body 20 and the cover 19 are not limited. May be connected by a thin hinge (not shown) so as to be openable and closable.

In the above embodiment, the plate 12 is locked from above the protector 4.
It is not always necessary to be in this direction. For example, a configuration in which the protector is placed vertically and the plate is locked from the lateral direction, or a configuration in which the plate is locked from under the protector can be used. In this case, the upper wall 1 of the protector 4
1 may be a side wall or a lower wall.

The above configuration is not limited to the locking between the harness protector 4 and the kicking plate 12, but may be, for example, a locking structure between the harness protector and another plate, panel, or vehicle body, or a harness for fixing the wire harness by tape winding or the like. A locking structure between a clamp (not shown) and another plate, panel, or vehicle body, a locking structure between a connector bracket (not shown) holding a plurality of connectors, and another plate, panel, or vehicle body, etc. It is applicable also in.

[0036]

As described above, according to the first aspect of the present invention, the two articles are locked by inserting the claw member of the other article between the claw member of one article and the arm member. It can be easily performed, and the locking workability is improved. Further, even if vibration of the vehicle or the like acts in the locked state of the two articles, the locking force is always secured by the pressing force of the arm member. Reliability is improved.

According to the second aspect of the present invention, when the claw members of both articles are engaged with each other, the arm member is bent at both the distal end side and the base end side, so that the stress of the arm member is dispersed, and the claw is disengaged. The insertion of the member can be performed more easily with a small force, and no excessive force is applied to the bent portion of the arm member, preventing a decrease in the elastic force of the arm member and deterioration of the material, thereby locking the two articles. Reliability is further improved. Further, since the pressing portion at the tip of the arm member presses against the claw member of the other article by surface contact, the pressing force is increased, and the pressing force is stably exhibited,
The reliability of the locking of both articles is further improved.

According to the third aspect of the present invention, when the two articles are detached (the two articles are unlocked), the other article is strongly pulled with respect to the one article, so that the other article is pulled. Since the claw member is guided in the detaching direction along the inclined locking surface of the claw member of one of the articles, detachment is relatively easily performed, and the maintainability and recyclability of the article are improved.

According to the fourth aspect of the present invention, when the two articles are detached (unlocking the two articles), the other article is strongly pulled with respect to the one article, so that the one article is removed. Since the claw member is guided in the detaching direction along the inclined locking surface of the claw member of the other article, the detachment is relatively easily performed, and the maintainability and recyclability of the article are improved. In particular, the combination of the inclined engagement surface of the claw member of one article and the inclined engagement surface of the claw member of the other article further improves the maintainability and recyclability of the article.

According to the fifth aspect of the present invention, when the two articles are locked, the claw member of the other article smoothly and lowly moves along the tapered guide inclined surfaces with the claw member and the arm member. Since it is inserted between them, the locking workability is improved. This is particularly effective when a plurality of sets of claw members and arm members are provided to lock a long article.

According to the sixth aspect of the present invention, since the protection plate is easily and securely attached to the harness protector, the workability in assembling is improved. In addition, since the protection plate is easily detached from the harness protector, maintenance of the wire harness and recyclability of the plate are improved. This is particularly effective when a plurality of sets of claw members and arm members are provided in locking the long harness protector with the plate.
