Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a fixture for a single electric wire used to securely hold an electric wire to a vehicle body, panel, etc. in automobiles and electrical appliances.

``Prior art'' and ``Problems to be solved by the invention'' Generally, when an electric wire pulled out from a wire harness is fixedly held on a car body, a wire holder with an elastic check piece erected on a board is used. In many cases, the electric wire to be held is fixed by being wrapped around the board with tape, and the elastic check piece is fitted into a mounting hole of the vehicle body to be fixedly held.

According to the above-mentioned fixing means, the work of winding the wire with tape around the board is complicated and troublesome, and the winding method varies, which makes the workability unfavorable, and the wire may not be fixed properly, resulting in poor wire retention performance. .

On the other hand, there are known examples of electric wire holders for stabilizing the holding of electric wires, such as Japanese Utility Model Publication No. 57-27028 and Japanese Utility Model Publication No. 56-37182. However, for example,
The method of No. 37182 has a disadvantage in that it lacks practical workability, as it requires the troublesome work of bending the upper wire, which has a complicated structure, into a small U-shape or omega-shape and inserting it into the insertion part.

The present invention was developed in consideration of the above-mentioned state of the art, and the purpose is to provide a fixture for a single wire that has a simple structure, excellent workability, and stable wire holding performance. .

``Means for Solving the Problems'' That is, the present invention that achieves the above object is provided with a locking head with an elastic check piece on one side of the plate-shaped base, and a locking head with an elastic check piece on the other side of the plate-shaped base. is provided with an electric wire holding part consisting of three locking hooks, and the locking hooks have an opening for receiving the electric wire from the side, and are connected to the opening to wrap and hold the outer circumference of a single electric wire. The openings of the locking hooks located at both ends of the three wire accommodating portions are formed narrower than the wire accommodating portions, and become elastic openings that receive the electric wires by elastic widening. A "locking claw to prevent the wire from coming off" is formed, and the openings of the three locking hooks are sequentially arranged in opposite directions to form a zigzag pattern by bending the center of a single wire held at three points. It consists of a structure that locks and holds the device in a fixed position.

"Example" and "Operation" A detailed explanation will be given below based on an example. In FIGS. 1 and 2 showing an embodiment thereof, the single electric wire fixture 1 of the present invention has a locking head 3 having a pair of elastic check pieces 4A4B at the center of one side of a plate-shaped base 2.
is erected, and when the locking head 3 is inserted into the mounting hole of the vehicle body, the umbrella-shaped elastic check piece 4A4B is elastically deformed and inserted, and the elastic check piece 4A4B is elastically engaged. The locking head 3 is fixed in the mounting hole.

On the other hand, on the other side of the base 2, three locking hooks 5A5B5C are arranged in parallel at required intervals along the longitudinal direction. That is, the locking hooks 5A to 5C constitute the wire holding part of the single wire holder 1, and are connected to an opening 6 that can receive a single wire from the side, and are connected to the opening 6 and inserted. A wire accommodating portion 7 is provided to hold the wire so as to wrap it around the outer periphery of the wire. The three locking hooks 5A to 5C bend the center of a single electric wire held at three points by the respective electric wire accommodating portions 7 and hold it in a zigzag shape, so that the openings 6 are sequentially oriented in opposite directions. are arranged in

That is, the locking hooks 5A5C located at both ends are arranged on the right side in the side view of FIG. 1B, and the locking hook 5B located at the center is arranged on the left side in the figure with the opening 6 facing. The locking hooks 5A5C at both ends are such that the opening 6 is narrower than the wire accommodating portion 7 and locking claws 8A8B are provided at both ends of the opening 6 in order to stabilize the housed electric wire. is elastically widened to receive the electric wire, and the electric wire accommodated in the electric wire accommodating portion 7 is configured to be locked and held by the locking pawl 8A8B so that it will not easily come out.

The elastic check valve 4A4B of the locking head 3 is given considerable rigidity, and its tip is bent in the opposite direction to form a reverse tapered locking portion 9. The tip of the locking part 9 and the periphery of the mounting hole in the vehicle body etc. are elastically engaged, and the locking head 3 is tightly fitted and fixed in the mounting hole in a non-returning manner, and cannot be easily pulled out under a pull-out load of, for example, 20 kg or less. It is structured like this.

Note that reference numeral 10 in the figure is a pressure contact piece provided at both ends of the base 2 to the vehicle body, etc., in order to prevent rattling during installation.

The single electric wire fixture 1 configured as described above has a locking hook 5.
The electric wires 11 to be held are hooked and housed in a zigzag pattern on A to 5C, and the locking head 3 is inserted into the mounting hole 1 of the vehicle body 12, etc.
3 in a non-returning manner, and connect a single electric wire 11 to the vehicle body 1.
Hold and fix it in 2nd class.

The above single electric wire fixture 1 of the present invention has three locking hooks 5 which have an opening 6 on the side and have a wire accommodating part 7 for wrapping and holding the outer circumference of a single electric wire as a main part.
A to 5C are provided, and the openings 6 are arranged in reverse order to be narrower than the wire accommodating portion 7, and "locking claws 8A8B for preventing wires from coming off" are formed on both sides of the entrance of the openings 6. When the electric wire 11 is sequentially pushed into the opening 6 of the locking hooks 5A to 5C, the opening 6 expands slightly elastically and accepts the electric wire 11 into the wire accommodating part 7 with a "snap". Store it in a way that it wraps around it.

As shown in FIG. 2B, the electric wire 11 is hooked and locked by three locking hooks 5A to 5C in a zigzag shape, and is held in a constant posture without variation.
Note that, after storing the wires 11 in the wire accommodating portion 7, if possible, the wires 11 extending on both sides may be pulled lightly by hand to apply tension, thereby making the holding posture more stable.

Then, the electric wires 11 in each electric wire storage section 7
Since there is a "claw 8A8B" at the entrance of the opening 6 of the narrow opening passage, its accommodation posture is locked and the wire 11 is prevented from being exposed to external forces such as normal vibrations, twisting, and lateral vibrations. Then, locking hooks 5A to 5C
The electric wire 11
Even if a pulling external force is generated in the longitudinal direction, the wire 11 locked in a zigzag shape with the three locking hooks 5A to 5C has a strong pulling force, and the holding position does not easily shift. is stably retained against any external force.

"Effects of the invention" As explained above, the single electric wire fixing device of the present invention requires only the electric wire 11 to be pushed into the three locking hooks 5A to 5C with a "snap", and is superior to conventional means. The work of fixing electric wires becomes easier. The electric wire 11 is fixedly held in a fixed position, and there is no fear that the electric wire 11 will come off or lose its position due to normal vibrations applied to the electric wire 11, and the fixed and held position is stable. There are practical effects achieved by the structure.
