Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a harness clamp that binds a harness to be wired to an engine room of an automobile and fixes the harness to a predetermined panel, for example.
[0002]
[Prior art]
As this type of conventional harness clamp, there is one shown in Japanese Utility Model Laid-Open No. 5-67806.
Although the conventional harness clamp is not specifically illustrated, it is an integrally molded product of synthetic resin, and has a pair of pressing walls projecting inward on the opposing inner surface of the C-shaped main body, A pair of locking leg pieces, which are fixed portions, are extended outward at both ends of the main body portion separated from each other.
[0003]
When actually binding the harness and fixing it to the panel side, the harness is inserted into the C-shaped main body while expanding the pair of locking leg pieces, and this time, the pair of locking legs When the leg pieces are closed and the pair of locking leg pieces are locked in the mounting holes formed on the panel side, the harness is held by the pair of hooks while being held inside the C-shaped main body. Since the pressure is pressed between the pressure walls, the harness is fixed in place in a bound state.
[0004]
[Problems to be solved by the invention]
Therefore, under the conventional harness clamp, there is an advantage that the harness can be easily bundled and fixed to the panel side, but on the other hand, the harness is moved in the axial direction in relation to peripheral devices, etc. When there is a need to change the wiring state, the harness is pressed between the pair of pressing walls, so it is difficult to move the harness freely inside the C-shaped main body. In addition, when it was moved forcibly, it was thought that there was a possibility that the insulation film of the harness could be damaged or broken due to the presence of the compression wall.
[0005]
[Means for Solving the Problems]
The present invention was developed in order to effectively solve the problems of the conventional harness clamp, and the invention according to claim 1 includes a main body for holding the harness and a fixing fixed to the panel side. The body clamp and the fixed part are obtained by closing a pair of split bodies in a half-split state, and each of the split bodies is connected to be opened and closed via a hinge part. Side walls for defining a cylindrical shape are provided on both end sides, and a holding piece having a plurality of protrusions formed on the inner surface in the longitudinal direction between the both side walls is provided through a pair of slits on both sides. The structure is constructed such that it can be bent with a state of projecting to the surface, and a tension operation part is provided on the outer surface of each holding piece.
[0006]
The invention described in claim 2 is based on the premise of claim 1 and adopts a configuration in which the tension operation portion is provided at the center portion of the outer surface that is recessed in the innermost side of each gripping piece.
Invention of Claim 3 is a harness clamp which consists of the main-body part which holds a harness, and the fixing | fixed part fixed to the panel side, Comprising: The said main-body part and a fixing | fixed part are a pair of half-split state Obtained by closing the divided bodies, each of the divided bodies being connected to each other through hinges so as to be openable and closable, and provided with side walls for defining a cylindrical shape at both ends thereof, and the length between the side walls. A gripping piece having a plurality of protrusions formed on the inner surface in the direction is constructed so as to be able to bend in a state of projecting inward, and a tension operation portion is provided on the outer surface of each gripping piece, while a pair of gripping pieces are pressed inwardly. A configuration having elastic biasing means was adopted.
[0007]
Therefore, in the invention according to claim 1, when the harness is placed on one inner surface of the divided body and the other divided body is closed to the one divided body side through the hinge portion, Since the main body and the fixing part are obtained at the same time, and the harness is held while being bound inside the main body, the fixing part is fixed to the panel side. It will be fixed.
However, in such a state, since the protrusion of each holding piece bites into the outer periphery of the harness from both sides, there is no concern that the harness moves in the axial direction inside the main body.
[0008]
Conversely, if it is necessary to change the wiring state by moving the harness in the axial direction in relation to peripheral devices, etc., this time, pull the pulling operation part and If each holding piece protruding inward is bent outward, the biting of the protrusion against the outer periphery of the harness can be easily released, so that the harness can be moved in the required axial direction to change its wiring state. It becomes possible to add.
[0009]
In the invention according to claim 2, since the pulling operation portion is provided in the central portion of the outer surface that is recessed in the innermost portion of the holding piece, when changing the wiring state, the protrusion bites against the outer periphery of the harness. Can be released efficiently.
In the invention of claim 3, as in claim 1, when the pair of divided bodies are closed together, the main body part and the fixing part are obtained at the same time, so the harness is held inside the main body part, If the fixing part is fixed to the panel side, the harness is fixed in place. In addition, when changing the wiring state of the harness, the wiring state can be changed by pulling the pulling operation portion to release the protrusions from the outer periphery of the harness. In addition, particularly in the invention according to claim 3, in addition to this, the presence of the elastic urging means makes it possible to forcibly press the holding piece toward the inside of the main body. The bundling state is further ensured, and unnecessary movement can be effectively prevented.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on a preferred embodiment. The harness clamp according to the first embodiment is also an integrally molded product of a synthetic resin. The main part and the fixed part are obtained by closing a pair of divided bodies in the following half-split state. In the point.
[0011]
Specifically, as shown in FIGS. 1 to 3, each of the pair of divided bodies 1 </ b> A and 1 </ b> B has a semi-cylindrical shape, and is connected to be opened and closed through the hinge portion 2 in an unfolded state. The side walls 3 for defining a cylindrical shape are provided on both end sides of each of the divided bodies 1A and 1B, and a plurality of triangular protrusions 5 are formed on the inner surface in the longitudinal direction between the side walls 3. The holding piece 4 is constructed so as to be able to bend in a state of being bent and protruded inward through a pair of lateral slits 6, and a tension that exhibits a U-shape at the center of the outer surface recessed in the innermost side of each holding piece 4 The operation unit 7 is integrally provided.
[0012]
In addition to this, two locking claws 8 are provided on the side edge of one divided body 1A, and two locking holes 9 are provided on the corresponding side edge of the other divided body 1B, thereby providing a pair of divided bodies. When 1A and 1B are closed together via the hinge part 2, each said latching claw 8 and each latching hole 9 will latch automatically, and it will become cylindrical by a pair of division body 1A and 1B. The locked main body A is obtained.
[0013]
In addition, rectangular stem walls 10A and 10B extending outward are individually connected to the outer intermediate portions of the side edges of the pair of divided bodies 1A and 1B, and the central portions of the stem walls 10A and 10B are connected to each other. A locking leg piece 11 having an overhanging shoulder portion 11a is formed through a pair of vertical slits 12, and a pressing operation portion 13 projecting outward is provided integrally on the free end side of each locking leg piece 11. At the same time, a locking claw 14 is provided at the distal end portion of one of the stem walls 10B, and a locking hole 15 is provided at the corresponding distal end portion of the other 10A so that the pair of divided bodies 1A and 1B are closed via the hinge portion 2. Similarly, the latching claw 14 and the latching hole 15 are latched so that the fixed portion B locked in a block shape can be obtained simultaneously on the lower side of the pair of divided bodies 1A and 1B. ing.
[0014]
In the figure, reference numeral 16 denotes convex portions provided on both sides of each of the stem walls 10A and 10B, and cooperates with the overhanging shoulder portion 11a of the locking leg piece 11 so as to be a hole for a mounting hole of a panel to be described later. The edge is gripped from the inside and outside, and the action of floating the pressing operation portion 13 upward from the panel surface by the height is also achieved.
[0015]
Therefore, when fixing the harness H to the panel P side while binding the harness H using the harness clamp having such a configuration, first, of the pair of divided bodies 1A and 1B in the unfolded state, When the harness H is placed on the inner surface and the other divided body is closed to one divided body side via the hinge portion 2, as shown in FIG. 4, it is provided on the side edge of each of the divided bodies 1A and 1B described above. Since the locking claw 8 and the locking hole 9 are locked at the same time, the locking claw 14 and the locking hole 15 provided on the stem walls 10A and 10B are also locked. The main body portion A is locked in a cylindrical shape along the longitudinal direction, and the fixing portion B is also locked in a block shape.
[0016]
Further, in such a state, the harness H is held while being bound inside the divided bodies 1A and 1B locked in a cylindrical shape. Then, it is merely movably held in the cylindrical shape defined by the side wall 3, but in the intermediate portion, the triangular protrusions 5 of the holding pieces 4 erected in a state of protruding inward are formed. Since it will bite into the outer periphery of the harness H from both sides, this can reliably prevent unnecessary movement of the harness H in a bundled state in the axial direction. Moreover, the fact that each holding piece 4 protrudes inward has an advantage that the variation in the diameter of the harness H can be effectively absorbed.
[0017]
Therefore, after that, when the fixing portion B locked in the block shape is inserted into the mounting hole Pa of the panel P, the action of the convex portion 16 is obtained as shown in FIG. Since the projecting shoulder portion 11a is elastically locked to the hole edge of the mounting hole Pa of the panel P, the harness H is thereby bound to the panel P side in place while being bound.
[0018]
When the harness H is fixed, for example, when the harness H needs to be moved in the axial direction in relation to peripheral devices and the like, the wiring state needs to be changed, as shown in FIG. As described above, when the pulling operation portion 7 provided on each holding piece 4 is pulled and the holding piece 4 protruding inward is forcibly bent outward, the harness H of the triangular protrusion 5 of each holding piece 4 is Since the bite to the outer periphery can be solved, the wiring state can be easily changed by moving the harness H in the necessary axial direction in this state. Needless to say, if the pulling of the pulling operation portion 7 is released after the change, each gripping piece 4 protrudes again inside the main body portion A, and the triangular protrusion 5 bites the outer periphery of the harness H.
[0019]
If it is necessary to remove the harness clamp itself from the panel P side while the harness H is bound, as shown in FIG. When each pressing operation portion 13 is pressed inward, the corresponding locking leg piece 11 is bent inward accordingly, and its overhanging shoulder portion 11a is removed from the hole edge of the mounting hole Pa of the panel P. Thereafter, if the fixing portion B is pulled out from the mounting hole Pa in this state, the harness clamp can be easily detached from the panel P side without being damaged.
[0020]
Next, the harness clamp according to the second embodiment will be described. The second embodiment basically follows the configuration of the first embodiment as it is, but the differences are as follows. As shown in FIG. 8, a C-shaped connecting wall 17 as an elastic urging means is integrally connected between the tension operation portions 7 provided on the outer surface of each holding piece 4, and the C-shaped center is formed. The concave hinge portion 18 is formed in the portion.
[0021]
Therefore, even under the second embodiment, when the pair of divided bodies 1A and 1B are closed together via the hinge portion 2, the locking claws 8 provided on the side edges of the divided bodies 1A and 1B are provided. 9 and the locking hole 9 are locked, and at the same time, the locking claw 14 and the locking hole 15 provided on the stem walls 10A and 10B are also locked. As a result, as shown in FIG. A is locked in a cylindrical shape, and the fixed portion B is also locked in a block shape. However, at this time, the relationship of L1 <L2 is established, and the relationship in which the center position Z of the connecting wall 17 is located below the hinge portion 2 is established, so that both ends of the connecting wall 17 are contracted. As a result, it is possible to press the holding pieces 4 further inwardly by the contracting force of the connecting wall 17, so that the triangular protrusions 5 are bitten more strongly on the outer periphery of the harness H.
[0022]
Therefore, in the second embodiment, unnecessary movement of the harness H in the bound state can be more reliably prevented. In addition, if the pulling operation part 7 is pulled, the harness H can be moved, and if the pressing operation part 13 is pressed, the harness clamp can be removed from the panel P side, and the like in the first embodiment. Since they are exactly the same, the description related to them is omitted here.
[0023]
【The invention's effect】
As described above, according to the present invention, by adopting the above configuration, under the first aspect, the harness is placed on one inner surface of the divided body, and the other divided body is connected to the one divided body side through the hinge portion. When the two are closed, the main body and the fixing portion are obtained at the same time, and the harness is held while being bound inside the main body, so that the fixing portion is fixed to the panel side thereafter. In this case, the harness is fixed in place.
However, in such a state, since the protrusion of each holding piece bites into the outer periphery of the harness from both sides, there is no concern that the harness moves in the axial direction inside the main body.
[0024]
Conversely, if it is necessary to change the wiring state by moving the harness in the axial direction in relation to peripheral devices, etc., this time, pull the pulling operation part and If each holding piece protruding inward is bent outward, the biting of the protrusion against the outer periphery of the harness can be easily released, so that the harness can be moved in the required axial direction to change its wiring state. It becomes possible to add.
[0025]
Under claim 2, since the tension operation part is provided in the central part of the outer surface that is recessed in the innermost part of the gripping piece, when the wiring state is changed, the biting of the protrusion on the outer periphery of the harness is efficiently released. it can.
Under the third aspect, similarly to the first aspect, when the pair of divided bodies are closed together, the main body portion and the fixing portion are obtained at the same time, so that the harness is held inside the main body portion, and the fixing portion is attached to the panel. If fixed to the side, the harness is fixed in place. In addition, when changing the wiring state of the harness, the wiring state can be changed by pulling the pulling operation portion to release the protrusions from the outer periphery of the harness. In addition, in particular, under the third aspect, in addition to this, the presence of the elastic biasing means makes it possible to force the holding piece to the inside of the main body, so that the harness is in a bound state. It becomes more reliable and can effectively prevent unnecessary movement.
