Description

Fixed structure

The present invention relates to a fixed structure.

When fixing a long member such as a control cable to the mounting target, a fixing structure is used in which the long member is fixed to the bracket provided on the mounting target so that the long member does not shift in the axial direction (for example, Patent Document). 1). This fixing structure includes an engaging portion that engages with a U-shaped groove provided in the bracket, a terminal member to which a long member is connected, and a clip attached to the terminal member. With the clip attached, the terminal member is attached to the groove of the bracket, and the engaging portion of the terminal member is engaged with the bracket. This restricts the terminal member from moving in the axial direction of the long member. Further, the clip has a pair of clip-side engaging portions that engage with each of the pair of bracket-side engaging portions provided in the groove of the bracket. When the clip-side engaging portion engages with the bracket-side engaging portion, the terminal member is prevented from being disengaged from the groove of the bracket in the direction perpendicular to the axis of the long member.

In Patent Document 1, the terminal member and the clip are attached to the bracket by pushing the clip into the groove of the bracket and deforming it so as to shorten the distance between the pair of clip-side engaging portions. Specifically, the clip and the terminal member are pushed in the depth direction of the groove in a state where the clip-side engaging portion having an inclined surface is in contact with the end edge of the bracket in which the groove is formed. Due to the reaction force applied to the engaging portion, the pair of clip-side engaging portions are deformed in the direction of approaching each other. When the pair of clip-side engaging portions reaches the bracket-side engaging portion, the deformed clip is restored and the clip-side engaging portion and the bracket-side engaging portion engage with each other.

As shown in FIGS. 4 and 5, the second engaging portion 42 is provided on the other end side of the mounting portion 43 in the circumferential direction of the mounting member 3. Further, as shown in FIGS. 1 and 4, the second engaging portion 42 is provided so as to project from the other end side of the mounting portion 43 in the second direction D2. As a result, with the clip 4 attached to the mounting member 3, the second engaging portion 42 is arranged at a position corresponding to the position of the shaft portion 33a that enters the mounting groove B2 in the axis X direction (FIG. 3). reference). As a result, when the shaft portion 33a is arranged in the mounting groove B2, the second engaging portion 42 engages with the second engaged portion B221.

The overall shape and structure of the second engaging portion 42 is that the second engaging portion 42 engages with the second engaged portion B22 and the mounting member 3 and the clip 4 move in the disengagement direction D12. Is not particularly limited as long as it can suppress. In the present embodiment, the second engaging portion 42 is formed as a convex portion protruding outward (in the direction away from the first engaging portion 41) in the third direction D3, as shown in FIGS. 4 and 5. ing. Details will be described later, but in the present embodiment, the second engaging portion 42 is used when the mounting member 3 and the clip 4 are mounted in the mounting groove B2 of the bracket B, as shown in FIGS. 1, 4 and 5. In addition, it has a second inclined surface 42a that abuts on the opening edge E that is on the end edge B1 side of the mounting groove B2. Further, in the present embodiment, the second engaging portion 42 engages with the second engaged portion B22 when a force is applied to the mounting member 3 and the clip 4 in the disengagement direction D12. It has 42b. In the present embodiment, as shown in FIGS. 4 and 5, in the second engaging portion 42, the second inclined surface 42a is provided on the insertion direction D11 side, and the second engaging surface 42b is provided on the disengagement direction D12 side. The second engaging portion 42 is provided and is formed as a substantially triangular convex portion.

Suppress. The second engaging surface 42b is provided on the side of the second engaging portion 42 in the disengagement direction D12. The second engaging surface 42b engages with the second engaged portion B22 provided so as to face the disengagement direction D12 side of the second engaging surface 42b. More specifically, the second engaging surface 42b is engaged with the first wall portion B221 provided on the disengagement direction D12 side of the second engaged portion B22 in the disengagement direction D12, whereby the second engagement surface 42b is second engaged. It is suppressed that the portion 42 is disengaged from the second engaged portion B22. The inclination angle of the second engaging surface 42b is provided so as to engage with the second engaged portion B22 and prevent the mounting member 3 and the clip 4 from being disengaged from the mounting groove B2 of the bracket B. It is not limited to the tilt angle shown in the figure.

The second inclined surface 42a is configured to abut on the opening edge E on the end edge B1 side of the mounting groove B2 when the mounting member 3 to which the clip 4 is mounted is inserted into the mounting groove B2. When the mounting member 3 is further pushed into the insertion direction D11 with respect to the bracket B in a state where the second inclined surface 42a is in contact with the opening edge E of the mounting groove B2, the second engaging portion is formed from the opening edge E. The second inclined surface 42a is inclined so that the 42 receives a reaction force that moves toward the first engaging portion 41 in the third direction D3. As a result, when the mounting member 3 to which the clip 4 is mounted is inserted into the mounting groove B2, the reaction force received by the second inclined surface 42a from the opening edge E causes the second engaging portion 42 to become the first engaging portion. The mounting portion 43 is elastically deformed so as to approach the 41 side, and the clip 4 can move in the mounting groove B2 in the insertion direction D11. In the present embodiment, as shown in FIGS. 4 and 5, the second inclined surface 42a is inside (the first engaging portion 41 and the second engaging portion 42) in the third direction D3 as it advances toward the insertion direction D11. It is tilted so as to approach (the intermediate position with). In the present embodiment, the second inclined surface 42a is composed of a flat surface, but may be slightly curved.

The connecting portion 44 is located on the detaching direction D12 side of the mounting member 3 with the clip 4 attached to the mounting member 3. The connecting portion 44 has elasticity that allows the first engaging portion 41 and the second engaging portion 42 to be separated from each other and close to each other. Therefore, when the first engaging portion 41 and the second engaging portion 42 are close to each other with respect to the initial state, the first engaging portion 41 and the second engaging portion 42 are separated from each other due to the elasticity of the connecting portion 44. When the first engaging portion 41 and the second engaging portion 42 are separated from each other with respect to the initial state, the first engaging portion 41 and the second engaging portion 42 are in close proximity to each other. Gives urgency.

The shape and structure of the connecting portion 44 are not particularly limited as long as they have elasticity that allows the first engaging portion 41 and the second engaging portion 42 to be separated from each other and close to each other. In this embodiment, as shown in FIGS. 4 and 5, the connecting portion 44 is bent in a zigzag shape. Specifically, the connecting portion 44 is configured in a bent plate shape, and the plate-shaped connecting portion 44 is provided so as to have a folded portion on the insertion direction D11 side and the disconnection direction D12 side.

In this embodiment, the clip 4 has a pair of knobs 45 as shown in FIGS. 4 and 5. The knob portion 45 is operated so as to approach each other in the third direction D3, thereby elastically deforming the mounting portion 43 so that the first engaging portion 41 and the second engaging portion 42 approach each other. As a result, the knob portion 45 is operated to engage the first engaged portion 41 with the first engaged portion B21 and engage the second engaged portion 42 with the second engaged portion B22. The mating can be released and the mounting member 3 can be detached from the bracket B. The shape of the knob portion 45 is not particularly limited as long as the mounting portion 43 can be elastically deformed so that the first engaging portion 41 and the second engaging portion 42 come close to each other by being operated so as to approach each other. .. In the present embodiment, the knob portion 45 is a plate continuously provided on the first engaging portion 41 and the second engaging portion 42 on the disengagement direction D12 side of the first engaging portion 41 and the second engaging portion 42. It is a piece.

Next, an example of the mounting process until the mounting member 3 is mounted on the bracket B will be described. The mounting process described below is merely an example, and the present invention is not limited to the following description.

First, as shown in FIG. 2, the clip 4 is attached to the attachment member 3 to which the long member 2 is connected. For example, as shown in FIG. 2, the clip 4 attaches the clip 4 from one end side of the second direction D2 of the mounting member 3 (in the present embodiment, the second connection portion 322 side) to the second direction D2 (axis X direction). ), And the clip 4 is attached to the attachment member 3. Specifically, as shown in FIGS. 2 and 3, the clip 4 is attached to the attachment member 3 by attaching the attachment portion 43 of the clip 4 to the attachment portion 31 of the attachment member 3.

As shown in FIGS. 1 and 3, when the clip 4 is connected to the mounting member 3, the mounting member 3 (long member assembly A) is mounted in the mounting groove B2 of the bracket B. Specifically, by moving the mounting member 3 with respect to the mounting groove B2 of the bracket B in the insertion direction D11, or by moving the bracket B with respect to the mounting member 3, the mounting member 3 becomes the bracket B. It is attached.

At this time, as shown in FIGS. 1 and 3, the mounting member 3 and the bracket B are arranged so that the holding portion 33 (shaft portion 33a) of the mounting member 3 is located at the position of the mounting groove B2 of the bracket B. Then, the mounting member 3 is inserted into the mounting groove B2 of the bracket B. As a result, the shaft portion 33a of the mounting member 3 enters from the insertion portion B23 of the mounting groove B2 toward the mounting portion B24.

When the mounting member 3 is pushed in the insertion direction D11 as it is, the first inclined surface 41a of the first engaging portion 41 and the second inclined surface 42a of the second engaging portion 42 come into contact with the opening edge E of the mounting groove B2. .. Although the details will be described later, when the mounting member 3 is pushed in the insertion direction D11 while the first inclined surface 41a and the second inclined surface 42a are in contact with the opening edge E of the mounting groove B2, the mounting member 3 is added from the opening edge E. The reaction force on the first inclined surface 41a and the second engaging portion 42 elastically deforms the mounting portion 43 so that the first engaging portion 41 and the second engaging portion 42 come close to each other. As a result, the first engaging portion 41 and the second engaging portion 42 engage with the first engaged portion B21 and the second engaged portion B22, respectively, as shown in FIG. 10, and the mounting member 3 Is attached to the bracket B.

When the force in the detachment direction D12 is applied to the attachment member 3 in this mounting completed state, the force in the detachment direction D12 is transmitted from the attachment member 3 to the clip 4. In the clip 4, since the first engaging portion 41 and the second engaging portion 42 are engaged with the first engaged portion B21 and the second engaged portion B22, respectively, the movement of the clip 4 in the disengagement direction D12. Is suppressed. As a result, the movement of the mounting member 3 to which the clip 4 is mounted in the detaching direction D12 is also suppressed.

In the present embodiment, when the mounting member 3 and the clip 4 are mounted in the mounting groove B2 of the bracket B, the first engaging portion 42 is first engaged before reaching the second engaged portion B22. As shown in FIGS. 5 and 7, the angle θ1 of the first inclined surface 41a with respect to the end edge B1 of the bracket B is such that the portion 41 reaches the first engaged portion B21. Is larger than the angle θ2 with respect to the edge B1. Here, the angle θ1 of the first inclined surface 41a with respect to the end edge B1 of the bracket B is an end when it is assumed that the first inclined surface 41a and the second inclined surface 42a abut on the end edge B1 of the bracket B at the same time. The angle (acute angle) between the edge B1 and the first inclined surface 41a. As shown in FIGS. 1 and 6, when the opening edge E has the tapered portion T, the angle θ1 is between the line extending the end edge B1 of the bracket B and the first inclined surface 41a. The angle of. Further, when the first inclined surface 41a is slightly curved, the angle θ1 is the tangent line at the point where the first inclined surface 41a and the edge B1 (opening edge E) are in contact with each other, and the edge B1 (or the end). The angle between the edge B1 and the extended line). Similarly, the angle θ2 of the second inclined surface 42a with respect to the edge B1 of the bracket B is the end when it is assumed that the first inclined surface 41a and the second inclined surface 42a abut on the edge B1 of the bracket B at the same time. The angle (acute angle) between the edge B1 and the second inclined surface 42a. Further, as shown in FIGS. 1 and 6, when the opening edge E has the tapered portion T, the angle θ2 is between the line extending the end edge B1 of the bracket B and the second inclined surface 42a. The angle of. Further, when the second inclined surface 42a is slightly curved, the angle θ2 is the tangent line at the point where the second inclined surface 42a and the edge B1 (opening edge E) are in contact with each other, and the edge B1 (or the end). The angle between the edge B1 and the extended line).

The angle θ1 and the angle θ2 are set before the second engaging portion 42 reaches the second engaged portion B22 when the mounting member 3 and the clip 4 are mounted in the mounting groove B2 of the bracket B. The first engaging portion 41 is not particularly limited as long as it is set to reach the first engaged portion B21. If the angle θ1 is larger than the angle θ2, a predetermined effect can be obtained. The difference between the angle θ1 and the angle θ2 is not particularly limited, but can be, for example, 3 ° to 20 °, preferably 5 ° to 10 °. By setting the difference between the angle θ1 and the angle θ2 to 3 ° to 20 °, preferably 5 ° to 10 °, the insertion force when the mounting member 3 is mounted on the bracket B is easily reduced as described later. Can be made to. The respective angles of the angle θ1 and the angle θ2 are not particularly limited as long as there is an angle difference between the angle θ1 and the angle θ2. It may be appropriately changed depending on various conditions such as the shape of the opening edge E of the bracket B. The angle θ1 can be 30 ° to 70 °, preferably 50 ° to 60 °, and the angle θ2 can be 20 ° to 60 °, preferably 45 ° to 55 °. In this embodiment, when the tapered portion T is provided at the opening edge E of the bracket B and the tapered portion is provided as shown in FIG. 6 (the tapered portion T and the insertion indicated by the alternate long and short dash line). The angle between the portion B23 and the portion B23 is, for example, 60 °), and the case where the mounting groove B2 extends perpendicularly to the end edge B1 at the opening edge E of the bracket B as shown in the schematic view of FIG. The sizes of the angle θ1 and the angle θ2 may be appropriately changed so that the mounting member 3 can be easily mounted on the bracket B.

As described above, in the present embodiment, as shown in FIG. 7, the angle θ1 of the first inclined surface 41a with respect to the edge B1 of the bracket B is larger than the angle θ2 of the second inclined surface 42a with respect to the end edge B1. Is also big. In this case, when the mounting member 3 and the clip 4 are mounted on the bracket B, as shown in FIGS. 8 and 9, the first engaging portion 41 precedes the second engaging portion 42 in the insertion direction D11. The first engaging portion 41 engages with the first engaged portion B21 before the second engaging portion 42 moves and engages with the second engaged portion B22. Therefore, when the mounting member 3 and the clip 4 are mounted on the bracket B, it is not necessary to elastically deform the first engaging portion 41 side and the second engaging portion 42 side of the mounting portion 43 at the same time. Therefore, the insertion force when the mounting member 3 and the clip 4 are mounted on the bracket B can be reduced.

Specifically, as shown in FIG. 7, when the mounting member 3 to which the clip 4 is mounted is inserted into the mounting groove B2 of the bracket 3, the opening edge E of the mounting groove B2 is tentatively inserted from the first engaging portion 41. It is assumed that the force indicated by the arrow F1 is applied, and the same force F1 is applied from the second engaging portion 42 to the opening edge E of the mounting groove B2. On the first engaging portion 41 side, the force F1 can be divided into a component force F2 and a component force F3, and a reaction force F4 is applied to the first engaging portion 41 from the opening edge E of the mounting groove B2. On the second engaging portion 42 side, the force F1 can be divided into a component force F20 and a component force F30, and a reaction force F40 is applied to the second engaging portion 42 from the opening edge E of the mounting groove B2.

As shown in FIG. 7, since the angle θ1 of the first inclined surface 41a with respect to the edge B1 is larger than the angle θ2 of the second inclined surface 42a with respect to the end edge B1, the first engaging portion 41 has the mounting groove B2. The component force F3 that is the force that advances in the insertion direction D11 is larger than the component force F30 that is the force that the second engaging portion 42 advances in the insertion direction D11 of the mounting groove B2. Therefore, as shown in FIGS. 8 and 9, the first engaging portion 41 moves in advance of the second engaging portion 42 in the insertion direction D11. Therefore, for example, as shown in FIG. 9, after the first engaging portion 41 engages with the first engaged portion B21, the second engaging portion 42 engages with the second engaging portion B22. By pushing the mounting member 3 to which the clip 4 is attached, the second engaging portion 42 can be engaged with the second engaged portion B22 as shown in FIG. At this time, the force for pushing the mounting member 3 to which the clip 4 is mounted does not need to elastically deform the already engaged first engaging portion 41 side, and the second engaging portion 42 is moved by a predetermined amount in the third direction. Only a force for elastically deforming the D3 is required, and the mounting member 3 can be mounted with a low insertion force.

Further, in the present embodiment, the horizontal component force F5 of the reaction force F4 from the opening edge E to the first engaging portion 41, which is a force that deforms the mounting portion 43 inward on the first engaging portion 41 side. Is greater than the horizontal component force F50 of the reaction force F40 from the opening edge E to the second engaging portion 42, which is the force that causes the mounting portion 43 to deform inward on the second engaging portion 42 side. Therefore, the mounting portion 43 is more deformed inward on the first engaging portion 41 side than on the second engaging portion 42 side, and the first engaging portion 41 is larger than the second engaging portion 42. It becomes easy to move in the insertion direction D11 in advance.

Further, in the present embodiment, as shown in FIGS. 5 and 10, the first engaged portion B21 and the second engaged portion B22 are symmetrical in the third direction D3, and the first engaging surface. The 41b and the second engaging surface 42b are symmetrical in the third direction D3. More specifically, the first wall portion B211 of the first engaged portion B21 and the first wall portion B221 of the second engaged portion B22 are symmetrical in the third direction D3 at the same inclination angle (in FIG. 10). , Symmetrical to the center line extending in the first direction D1 that symmetrically separates the mounting groove B2). Further, the first engaging surface 41b and the second engaging surface 42b are provided symmetrically in the third direction D3 at the same inclination angle. In this case, for example, when a force for the mounting member 3 to be detached from the bracket B is applied due to vibration applied to the long member 2, the mounting portion 43 is different from the case where the mounting member 3 is inserted into the mounting groove B2. A force that elastically deforms both the 1 engaging portion 41 side and the 2nd engaging portion 42 side at the same time is required. Therefore, in the present embodiment, the insertion force of the mounting member 3 provided with the clip 4 into the bracket B can be reduced as described above, but the structure is such that the attachment member 3 is difficult to be detached from the bracket B.
