Description

  The present invention relates to a clamp structure for clamping a cord-like held member that is routed in a vehicle.

  In a vehicle such as an automobile, for example, various hoses such as an evaporation hose, a breather hose, and a fuel hose that connect a fuel tank and an engine are routed. Various hoses have different diameters depending on the type of gas or liquid passing through the hose or its function.

  Various hoses arranged in the vehicle are held members that are clamped and held by a clamp structure attached to a vehicle-mounted component such as a fuel tank so that the hoses are not moved by the movement of the vehicle. Such a clamp structure is required to stably hold various hoses so that the various hoses do not move even when a vehicle vibration or the like occurs.

  Therefore, it is conceivable to prepare molding dies according to the diameters of various hoses and to mold various clamp structures using them. However, in this case, as many molding dies as the number of diameters are required, and the manufacturing cost increases. Therefore, ideally, it is preferable to clamp various hoses having different diameters with the same clamp structure formed with the same molding die.

  Patent Document 1 describes a clamp structure that forms a ring-shaped opening shape by fitting a pair of clamp pieces, which are elastic members, together. In this clamp structure, at least two pairs of protrusions are provided on the opening-shaped inner wall formed by the pair of clamp pieces at positions facing the center of the opening shape.

  In patent document 1, since the variation in the outer diameter of the hose is allowed in the entire clamp piece, the restriction (pressing force) by the protrusion can be suppressed, and the deterioration of the hose can be suppressed.

JP 2014-43909 A

  However, when the same clamp structure is used for hoses with various diameters as in Patent Document 1, the following problems occur. In other words, the gap between the two increases through the hose with a narrow hose diameter to the clamp structure for a large hose diameter, and the hose is unstable. The hose is damaged. If vibration from the road surface or the engine further propagates to the clamp structure that clamps the hose having such an incompatible diameter, the hose is fixed or the damage of the hose is worsened.

  In view of such a problem, an object of the present invention is to provide a clamp structure capable of stably fixing cable-shaped held members having various diameters.

  In order to solve the above-described problems, a typical structure of a clamp structure according to the present invention is a clamp structure for clamping a cord-like held member that is routed in a vehicle. A main body portion that is annularly surrounded over the range of the main body portion, and a main body portion in which an entrance / exit through which the member to be held can enter and exit is formed in the longitudinal direction, and is folded inward from a longitudinal end portion of the main body portion along the longitudinal direction. And at least one contact piece that elastically deforms by contacting the outer periphery of the held member.

  According to the above configuration, the abutting piece comes into contact with the outer periphery of the held member while being elastically deformed in a state where a part of the outer periphery of the held member such as a hose is surrounded by the main body. Therefore, even if the diameter of the member to be held is variously different, the member to be held can be held while the contact piece is elastic. For this reason, according to the said structure, even if a to-be-held member moves with the vibration of a vehicle, etc., a contact piece will elastically deform following this movement. Therefore, it is possible to stably fix the held member without damaging the held member while allowing the held member to move.

  The at least one abutting piece includes a pair of abutting pieces, and a line segment connecting the one pair of abutting pieces in the cross section of the main body portion has a diameter of the main body portion, and a pair of folded back contacts. The ends of the contact pieces may be oriented in opposite directions in the longitudinal direction. In this way, the one set of contact pieces is disposed facing each other, and is further folded from the upper end portion and the lower end portion of the main body portion. Therefore, with respect to the movement in the direction orthogonal to the longitudinal direction of the held member, the pair of abutting pieces can elastically deform following the held member while ensuring a good contact state with the held member. For this reason, a to-be-held member can be fixed stably. In addition, with respect to the movement of the held member along the longitudinal direction, the set of contact pieces are in surface contact with the held member, respectively, and any one of the contact pieces generates resistance. For this reason, the movement of the held member can be restricted.

  The at least one abutting piece may include a coming-out preventing abutting piece formed in the vicinity of the entrance / exit. Thereby, even if the held member tries to come out from the entrance / exit of the main body portion, the coming-out preventing contact piece is formed in the vicinity of the entrance / exit, so that the held member can be hardly pulled out from the main body portion.

  The at least one abutting piece includes two sets of abutting pieces, and a line segment connecting the two sets of abutting pieces in the cross section of the main body portion may have a diameter of the main body portion. Accordingly, the held member can be stably fixed for a long time at the center of the main body by the two sets of contact pieces. If the held member is fixed at a position deviated from the center of the main body, one of the contact pieces comes into contact with the held member more strongly than the other contact pieces, which may be caused by vehicle vibration. It will be rubbed and it will become difficult to fix stably for a long time.

  The length of the at least one contact piece along the longitudinal direction may be equal to the length of the main body portion along the longitudinal direction. Thereby, since the contact piece extends to the inner side of the main body portion, even a member to be held having a smaller diameter can be stably fixed. Moreover, since the contact area of the contact piece with respect to the held member is increased, it is possible to stabilize the held member more stably and to further restrict the movement of the held member.

  ADVANTAGE OF THE INVENTION According to this invention, the clamp structure which can fix stably the cable-shaped to-be-held member of various diameters can be provided.

  The main body 130 of the clamp structure 100 is formed of an elastic member such as resin, and has a substantially C shape as shown in FIG. 2A, and can be elastically deformed so that the hose 126 can enter and exit from the entrance 132. It is.

  The clamp structure 100 further includes two sets of contact pieces 136, 138, 140, 142 that elastically deform by contacting the outer periphery 134 of the hose (see FIG. 3) with the hose 126 clamped. As shown in FIG. 2A, the pair of contact pieces 136 and 138 are arranged facing each other. For example, the contact piece 136 is formed near the entrance / exit 132 of the main body 130. 2B, the contact piece 136 is folded inward from the upper end 144 in the longitudinal direction of the main body 130, and is inclined so as to be located inward as it extends downward along the longitudinal direction. doing.

  On the other hand, as shown in FIG. 2B, the contact piece 138 is folded inward from the lower end portion 146 in the longitudinal direction of the main body 130, and is positioned so as to be located inward as it extends upward in the longitudinal direction. It is inclined to. That is, the end portion 148 of the contact piece 136 and the end portion 150 of the contact piece 138 are directed in directions opposite to each other in the longitudinal direction of the main body 130. The dimension Lb, which is the length of the contact pieces 136, 138 along the longitudinal direction, is equal to the dimension La, which is the length of the main body 130 along the longitudinal direction.

  As shown in FIG. 2A, the pair of contact pieces 140 and 142 are disposed facing each other. As shown in FIG. 2C, the contact piece 140 is folded inward from the lower end portion 146 in the longitudinal direction of the main body 130, and is inclined so as to be located inward as it extends upward in the longitudinal direction. doing.

  On the other hand, the contact piece 142 is formed in the vicinity of the entrance / exit 132 of the main body 130. As shown in FIG. 2C, the contact piece 142 is folded inward from the upper end 144 in the longitudinal direction of the main body 130, and is inclined so as to be located inward as it extends downward along the longitudinal direction. doing. That is, the end 152 of the contact piece 140 and the end 154 of the contact piece 142 are directed in directions opposite to each other in the longitudinal direction of the main body 130. In addition, the dimension Lb that is the length of the contact pieces 140 and 142 along the longitudinal direction is equal to the dimension La that is the length of the main body 130 along the longitudinal direction.

  Next, the clamp structure 100 with the hose 126 clamped will be described. FIG. 3 is a view taken in the direction of arrow D in FIG. As shown in FIG. 3, in the clamp structure 100, when the hose 126 is inserted from the entrance / exit 132 of the main body part 130 toward the center part E, the main body part 130 is elastically deformed and surrounds the hose 126 in an annular shape.

  Further, as shown in the figure, the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 are in contact with the outer periphery 134 of the hose 126 and elastically deformed. Furthermore, line segments 156 and 158 connecting the first set of contact pieces 136 and 138 and the second set of contact pieces 140 and 142 respectively form the diameter of the main body 130, and the center of the main body 130. Cross at part E.

  FIG. 4 is a diagram illustrating a BB cross section of the clamp structure 100 of FIG. 3. FIG. 4A is a cross-sectional view taken along the line BB in FIG. In the figure, arrows F and G indicate the downward and upward force directions received by the hose 126. 4 (b) and 4 (c) show the behavior of the set of contact pieces 136 and 138 when the hose moves in the directions indicated by arrows H and I, respectively.

  As shown in FIG. 4A, the first set of contact pieces 136 and 138 abuts on the outer periphery 134 of the hose 126 and elastically deforms so that the inner surfaces 136a and 138a are brought into contact with the outer periphery 134 of the hose 126, respectively. Surface contact. In this state, when the hose 126 receives the downward force indicated by the arrow F, the inner surface 136a of the contact piece 136 presses the outer periphery 134 of the hose 126 inward mainly in the vicinity of the end portion 148, for example. For this reason, the resistance against the downward movement of the hose 126 is generated mainly by the inner surface 136a of the contact piece 136 of the first set of contact pieces 136 and 138. Can regulate movement.

  On the other hand, when the hose 126 receives an upward force indicated by an arrow G, the inner surface 138a of the contact piece 138 presses the outer periphery 134 of the hose 126 inward mainly in the vicinity of the end 150, for example. For this reason, the resistance against the upward movement of the hose 126 is generated mainly by the inner surface 138a of the contact piece 138 of the first set of contact pieces 136 and 138. Can regulate movement.

  Here, the hose 126 may move in a direction orthogonal to the longitudinal direction, for example, when a force is applied in the vertical direction. As an example, as shown in FIG. 4B, when the hose 126 moves in the direction indicated by the arrow H, the first set of contact pieces 136 and 138 are hose on the inner surfaces 136a and 138a near the end portions 148 and 150 thereof. The outer periphery 134 of the 126 is pressed inward, and the outer surfaces 136b and 138b come into contact with the main body 130 to generate friction. As a result, the first set of contact pieces 136 and 138 can regulate the vertical movement of the hose 126 while following the movement of the hose 126 in the direction indicated by the arrow H.

  As shown in FIG. 4C, when the hose 126 moves in the direction indicated by the arrow I, the first set of contact pieces 136 and 138 are elastically deformed, and the entire surface of the inner surfaces 136a and 138a is hose 126. Surface contact with the outer periphery 134. As a result, the first set of contact pieces 136 and 138 can regulate the movement of the hose 126 in the vertical direction while following the movement of the hose 126 in the direction indicated by the arrow I.

  FIG. 5 is a diagram for explaining a CC cross section of the clamp structure 100 of FIG. 3. Fig.5 (a) is CC sectional drawing of FIG. FIGS. 5B and 5C show the behavior of the second set of contact pieces 140 and 142 when the hose 126 moves in the directions indicated by arrows J and K. FIG.

  As shown in FIG. 5A, the second set of contact pieces 140 and 142 abuts on the outer periphery 134 of the hose 126 and elastically deforms so that the inner surfaces 140 a and 142 a are brought into contact with the outer periphery 134 of the hose 126. Surface contact. In this state, when the hose 126 receives the downward force indicated by the arrow F, the inner surface 142a of the contact piece 142 presses the outer periphery 134 of the hose 126 inward mainly near the end 154, for example. For this reason, the resistance against the downward movement of the hose 126 is generated mainly by the inner surface 142a of the contact piece 142 of the second set of the contact pieces 140, 142. Can regulate movement.

  On the other hand, when the hose 126 receives an upward force indicated by the arrow G, the inner surface 140a of the contact piece 140 presses the outer periphery 134 of the hose 126 inward mainly in the vicinity of the end portion 152, for example. For this reason, the resistance against the upward movement of the hose 126 is generated mainly by the inner surface 140a of the contact piece 140 of the second set of the contact pieces 140, 142. Can regulate movement.

  Further, as shown in FIG. 5B, when the hose 126 moves in the direction indicated by the arrow J, the second set of contact pieces 140 and 142 are elastically deformed and the entire surface of the inner surfaces 140a and 142a is hose 126. Surface contact with the outer periphery 134. As a result, the second set of contact pieces 140 and 142 can regulate the vertical movement of the hose 126 while following the movement of the hose 126 in the direction indicated by the arrow J.

  Further, as shown in FIG. 5 (c), when the hose 126 moves in the direction indicated by the arrow K, the second set of contact pieces 140, 142 are hose 126 on the inner surfaces 140a, 142a near the end portions 152, 154 thereof. The outer periphery 134 is pressed inward, and the outer surfaces 140b and 142b come into contact with the main body 130 to generate friction. As a result, the second set of contact pieces 140 and 142 can regulate the vertical movement of the hose 126 while following the movement of the hose 126 in the direction indicated by the arrow K.

  As described above, in the clamp structure 100 of the present embodiment, when the hose 126 is clamped, two sets of contact pieces 136 are formed on the outer periphery 134 of the hose 126 in a state where a part of the outer periphery 134 of the hose 126 is surrounded by the main body 130. 138 and the contact pieces 140 and 142 are in contact with each other while being elastically deformed. For this reason, in the clamp structure 100, even if the diameter of the hose 126 varies, the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 can hold the hose 126 while maintaining elasticity. Therefore, even when the hose 126 having various diameters moves due to the vibration of the vehicle, the two contact pieces 136 and 138 and the contact pieces 140 and 142 follow the movement of the hose 126. Can be elastically deformed. Therefore, according to the clamp structure 100, it is possible to stably fix the hose 126 without damaging the hose 126 while allowing the hose 126 to move.

  Further, the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 are arranged facing each other, and are further folded from the upper end portion 144 and the lower end portion 146 of the main body portion 130, respectively. Therefore, in the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142, end portions 148, 150, 152, and 154 are directed in directions opposite to each other in the longitudinal direction of the main body 130.

  Therefore, in the clamp structure 100, the two contact pieces 136 and 138 and the contact pieces 140 and 142 ensure a balanced state of contact with the hose 126 with respect to the movement in the direction orthogonal to the longitudinal direction of the hose 126. However, the hose 126 can be elastically deformed following the hose 126, and the hose 126 can be stably fixed. Further, the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 are in surface contact with the hose 126 with respect to the movement along the longitudinal direction of the hose 126, and further, any one of the contact pieces resists the movement. Therefore, the movement of the hose 126 can be restricted.

  Also, line segments 156 and 158 connecting the first set of contact pieces 136 and 138 and the second set of contact pieces 140 and 142 respectively form the diameter of the main body 130 and intersect at the center E of the main body 130. doing. For this reason, according to the clamp structure 100, the hose 126 can be stably fixed for a long period of time at the center E of the main body 130 by the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142. If the hose 126 is fixed at a position deviated from the center E of the main body 130, one of the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 becomes another contact piece. Compared to the hose 126, the hose 126 is strongly abutted and rubbed by the vibration of the vehicle. As a result, it is difficult to stably fix the hose 126 for a long period of time.

  The dimension Lb which is the length of the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 along the longitudinal direction of the main body 130 is the dimension La which is the length of the main body 130 along the longitudinal direction. be equivalent to. That is, since the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 extend to the inner side of the main body 130, even the hose 126 having a smaller diameter can be stably fixed. In addition, since the contact area between the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 with respect to the hose 126 is increased, the fixing of the hose 126 can be made more stable and the movement of the hose 126 can be more restricted. Since the dimensions La and Lb are equal, the clamp structure 100 including the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 can be easily injection-molded, for example.

  The contact pieces 136 and 142 are formed in the vicinity of the entrance / exit 132 of the main body 130. For this reason, even if the hose 126 tries to come out from the entrance / exit 132 of the main body 130, the contact pieces 136, 142 function as a coming-out prevention contact piece, and the hose 126 can be made difficult to come off from the main body 130.

  In the above-described embodiment, the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 arranged on the opposite sides contact the outer periphery 134 of the hose 126. However, the present invention is not limited to this. As long as the hose 126 can be stably fixed by following the elastic deformation, the arrangement and number of contact pieces may be changed as appropriate. For example, instead of the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142, one set of contact pieces may be used, or three or more sets of contact pieces may be used.

  FIG. 6 is a view showing a clamp structure 100A according to another embodiment of the present invention. 6 (a) and 6 (b) correspond to the BB cross section of FIG. 4 (a) and the CC cross section of FIG. 5 (a), respectively.

  The clamp structure 100A differs from the clamp structure 100 described above in that the arrangement of the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 is changed.

  That is, in the clamp structure 100A, as shown in FIG. 6A, the contact piece 136 and the contact piece 142 face each other as the first set of contact pieces. Therefore, the first set of contact pieces 136 and 142 that face each other are folded back from the upper end 144 in the longitudinal direction of the main body 130 and extend downward along the longitudinal direction. Therefore, the end portions 148 and 154 of the first set of contact pieces 136 and 142 are directed in the same direction in the longitudinal direction of the main body 130.

  In the clamp structure 100A, as shown in FIG. 6B, the contact piece 138 and the contact piece 140 face each other as the second set of contact pieces. Therefore, the second set of contact pieces 138 and 140 facing each other are folded inward from the lower end 146 in the longitudinal direction of the main body 130 and extend upward along the longitudinal direction. Therefore, the end portions 150 and 152 of the second set of contact pieces 138 and 140 are directed in the same direction in the longitudinal direction of the main body 130.

  Even in such a clamp structure 100A, the first set of contact pieces 136 and 142 and the second set of contact pieces 138 and 140 arranged on the opposite side contact the outer periphery 134 of the hose 126 and elastically deform. Since they are in surface contact, the hoses 126 having different diameters can be stably fixed.

  FIG. 7 is a diagram showing clamp structures 100B and 100C according to still another embodiment of the present invention. The clamp structure 100B shown in FIG. 7A differs from the clamp structure 100A shown in FIG. 2A in that the positions of the second set of contact pieces 140 and 142 are interchanged. That is, in the clamp structure 100 </ b> B, the contact pieces 136 and 140 are formed near the entrance / exit 132 of the main body 130.

  Even in such a clamp structure 100B, the contact pieces 136 and 140 function as contact pieces for preventing the removal, and two sets of contact pieces 136 and 138 and the contact pieces 140 and 142 are provided on the outer periphery of the hose 126. Since it abuts on 134 and elastically deforms, the hoses 126 having different diameters can be stably fixed.

  The clamp structure 100C shown in FIG. 7B is the above-described clamp structure in that only one contact piece 136 is formed instead of the two sets of contact pieces 136 and 138 and the contact pieces 140 and 142. Different from 100.

  Even with such a clamp structure 100C, for example, when a bellows-shaped hose having a large diameter and an uneven surface is clamped, one contact piece 136 contacts the outer periphery of the hose and elastically deforms. Since the hose is pressed against the main body 130, such a hose can be stably fixed.

  In the above embodiment, the evaporative hose 126 is exemplified as the hose 126 to be clamped by the clamp structure 100. However, the hose 126 is not limited to this, and may be various types such as a breather hose and a fuel hose as long as it is a cord-like thing routed in the vehicle. A hose may be applied.

  Moreover, in the said embodiment, although the fuel tank 102 was illustrated as an in-vehicle component to which the clamp structure 100 is attached, it is not restricted to this, The clamp structure 100 is attached to an air-conditioning unit (HVAC), and a drainage hose is clamped as the hose 126. It may be.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.
