Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an electric wire protector, and more particularly to protection of an electric wire of, for example, an automobile.

(Prior Art) FIG. 7 shows a state in which a wire protector conventionally used, for example, in an automobile is used. The body 1a of the protector is a rectangular article having a U-shaped cross section and is integrally formed of resin or the like.
The electric wire 9a is placed in the main body of the electric wire protector, the electric wire protector main body is covered with a lid (not shown), or is sometimes used without a lid. At the entrance / exit of the body of the protector, the electric wire is fixed by a tape 10a or the like so that the electric wire does not vibrate in the body of the protector to make an abnormal noise or be damaged by vibration during driving of the automobile.

(Problems to be Solved by the Invention) However, the wire protector having the above structure is not sufficient for coping with vibration generated in an automobile or the like. For example, when the electric wire protector main body is fully laid with the electric wire and is covered with the electric wire, the electric wire rarely generates noise because the electric wire is tightly fixed. However, in this case, if there is no lid, the electric wire may be detached from the body of the protector due to vibration and the electric wire may be damaged. When the amount of the electric wire is small, a space is created in the protector body regardless of the presence / absence of the lid of the protector body, and the electric wire in the protector body vibrates due to the vibration during driving of the automobile. As a result, abnormal noise may occur, the arrangement of the electric wires may be disturbed, or the electric wires may be damaged. Then, this invention aims at eliminating the said inconvenience.

(Means for Solving the Problems) In order to solve the above problems, the wire protector of the present invention is configured as follows.

That is, a protector body having a U-shaped cross section with an open upper surface and accommodating a plurality of electric wires therein, an engaging portion formed on a side wall of the protector body, and an engaging portion attached to the engaging portion And a pressing member for holding the electric wire in a stored state, the pressing member includes a pressing piece for pressing the electric wire from the upper surface side of the protector body to the bottom plate, and one side of the pressing piece. The engaging piece is integrally formed.
Further, the engaging portion is formed with a hole formed so that the engaging piece can be inserted from the upper surface of the protector body toward the bottom plate, and communicates with the hole to prevent movement of the pressing piece when the engaging piece is inserted. The cutout portion is formed so as to be allowed, and a locking claw formed so as to be locked with the engaging piece on the inner surface of the hole.

Further, the number of the holding members may be two, the holding piece of one holding member may be provided with a connecting projection, and the holding piece of the other holding member may be formed with a connecting window slidably connected to the connecting projection. (Operation) After the electric wire is laid inside the body of the protector, the pressing member is inserted into the engaging portion provided on the inner side of the side wall until the pressing piece abuts and presses the electric wire to prevent the electric wire from vibrating. In this case, the structure is such that the vertical position of the pressing piece can be changed and locked depending on the amount of electric wire. Further, the pressing member is made up of two members, the connecting piece is provided on the pressing piece of one pressing member, and the connecting piece capable of slidably receiving and connecting the connecting projection is provided on the pressing piece of the other pressing member. Since the length can be freely selected, not only the vertical position of the pressing piece can be changed and locked according to the amount of the electric wire, but also the protective body of various widths can be applied.

The engaging portion 4 has a rectangular parallelepiped shape having the same height as that of the side wall 2 protruding inward from the side wall, and a hole 5 for inserting and locking the pressing member 20 is formed on the bottom plate 3 from the upper surface at a substantially central portion of the upper surface of the rectangular parallelepiped. It is built to face. Further, a rectangular notch 6 is formed on the side surface so that the pressing piece 21 can be moved in the vertical direction, and a cross-section for locking the engaging piece 22 is formed on the side wall 2 on the back surface of the notch 6. A trapezoidal locking claw 7 is projected. A tape winding portion 8 for fixing the electric wire 9 with a tape 10 or the like is provided on the end portion of the protective equipment main body 1 in a state of protruding from the bottom plate 3.

Next, the operation and usage of the first embodiment based on the above configuration will be described with reference to FIGS. 3 and 4. In FIG. 4, two engaging portions 4 are provided alternately on one side wall. First, a plurality of electric wires 9 are laid on the bottom plate 3 of the protector body 1 so that the thickness thereof is substantially uniform. Next, each pressing member 20 is pressed into the hole 5 formed in the engaging portion 4
Insert the wire 21 until it contacts and presses the wire 9. At this time, the pressing member 20 is elastically deformed and fitted and engaged by the locking claw 7 protruding from the side wall 2 and the locking claw 23 formed on the engaging piece 22, and the electric wire 9 is fixed to the pressing piece. It is stopped by 21. The vertical position of the pressing piece 21 can be adjusted by changing the position where the locking claw 23 and the locking claw 7 are fitted together. Therefore, the electric wire 9 can be pressed according to the amount of the electric wire 9 to be laid, and vibration of the electric wire can be prevented. The electric wire 9 is fixed to the entrance / exit of the protective equipment main body 1 with a tape 10 or the like including the tape winding portion 8.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIGS. 5 and 6. The side walls 2 and 2 have the same engaging portions 4 and 4 as in the first embodiment.
It is provided at a position facing 2,2.

The pressing member in this embodiment is composed of a pressing member 30a and a pressing member 30b that are substantially the same as those in the first embodiment. That is, the engaging piece 32
The shape of the engaging piece 34 is the same as that of the engaging piece 22 in the first embodiment, but the pressing pieces 31, 33 are different. A connecting projection 35 having a rectangular parallelepiped head is vertically provided at an end of the pressing piece 33, and a rectangular connecting window capable of slidably receiving and connecting the connecting projection 35 to one pressing piece 31. 36 are drilled.

(Effect of the Invention) As described above, according to the present invention, the pressing member including the pressing piece for pressing the electric wire and the engaging piece formed on one side of the pressing piece is attached to the side wall of the protector body in a cantilever manner. In addition, since the engaging piece of the pressing member is firmly inserted into the hole of the engaging portion formed in the side wall of the protector body, one kind of pressing member is provided for the protector body having different opening widths on the upper surface. Even if an external force such as vibration is applied to the body of the protector, and the relative amount of deformation or relative twisting with different deformation directions occurs on both side walls, the engaging piece of the pressing member engages with the engaging portion of the body of the protector. It is prevented from coming off. These effects are obtained not only when one pressing member is attached to one side wall of the protective equipment main body, but also when the two pressing members are attached to both side walls of the protective equipment main body. This can be achieved by slidably coupling, so that the electric wire is always held in a proper storage state.
