Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Embodiment 1 FIG.
1 is a diagram showing a configuration example of a wiring holding structure according to Embodiment 1 of the present invention.
The wiring holding structure is formed integrally with the casing surface 1 of the device and holds wiring (cable, cord, etc.) used for the device. The housing is made of a hard mold resin. As shown in FIG. 1, the wiring holding structure has a clamp portion 2 and a stopper portion 3.

The clamp part 2 is formed integrally with the housing surface 1 and sandwiches and holds the wiring.
The clamp portion 2 is provided with a pair of support portions 21 in which a root portion 211 is continuous with the housing surface 1. In the example of FIG. 1, the support portion 21 is configured to extend in a direction perpendicular to the housing surface 1. The pair of support portions 21 are configured to be elastically deformable outward in the facing direction. In addition, the arrangement interval and the length of the pair of support portions 21 are appropriately set according to the diameter and number of wires to be held.

In addition, the end portions of the pair of support portions 21 are respectively provided with claw portions 22 that protrude to face each other. The claw portion 22 forms a gap that allows wiring to be inserted when the pair of support portions 21 are elastically deformed outward, and the pair of support portions 21 return to the original state so that the inserted wires The support part 21 is sandwiched together.
In the example of FIG. 1, the clamp portion 2 is provided with an inclined portion 23 having a surface inclined along the support portion 21 from the end portion of the claw portion 22.

  The stopper portion 3 is formed integrally with the housing surface 1 and is disposed to face the clamp portion 2 in the opening direction. This stopper part 3 is arrange | positioned in the position which the said clamp part 2 contacts within the elastic limit in the root part 211 of the said clamp part 2 when the clamp part 2 is opened. This stopper part 3 regulates the deformation amount of the support part 21 when the support part 21 which opposes contacts.

Next, an example of the operation of attaching and removing the wiring to the wiring holding structure configured as described above will be described.
When attaching the wiring to the wiring holding structure, the operator first applies a force so as to open between the claws 22 of the clamp part 2 to elastically deform the support part 21 outward. Thereby, a gap into which the wiring can be inserted can be obtained between the claw portions 22. Then, the target wiring is inserted into the clamp portion 2 from between the claw portions 22. Thereafter, the force applied to the clamp portion 2 is released. Thereby, the support part 21 returns to an original state, and the nail | claw part 22 closes. As a result, the clamp unit 2 sandwiches and holds the wiring.
Further, when removing the wiring from the wiring holding structure, the operator may perform the operation opposite to the above.

Here, in the wiring holding structure of the present invention, when the support portion 21 is elastically deformed so as to open between the claws 22 of the clamp portion 2, a force exceeding a specified value within the elastic limit of the root portion 211 of the clamp portion 2. Is applied, the contact surface 212 of the support portion 21 comes into contact with the contact ridgeline 31 of the stopper portion 3 that faces the contact surface 212. Thereby, it can control that the support part 21 deform | transforms any more, and can prevent that the clamp part 2 bends or deform | transforms.
In other words, the clamp portion 2 can be opened by bending the support portion 21 as long as the support portion 21 is within a range until it comes into contact with the stopper portion 3. Therefore, the wiring can be smoothly attached and detached without worrying about breakage.

  In addition, although the contact surface 212 of the clamp part 2 and the contact ridgeline 31 of the stopper part 3 showed the form which contacted in the example of FIG. 1, it is not restricted to this. In other words, depending on the shapes of the clamp part 2 and the stopper part 3, there are various forms of contact such as a contact surface and a contact surface, a contact surface and a contact point, and a contact ridge line and a contact ridge line.

  In the example of FIG. 1, the clamp portion 2 is provided with an inclined portion 23 having a surface inclined along the support portion 21 from the end portion of the claw portion 22. Thereby, even if it is a case where wiring is roughly pulled out from the clamp part 2, since wiring moves along the surface of this inclination part 23, it can be made hard to damage a wiring.

  As described above, according to the first embodiment, the clamp portion 2 formed integrally with the housing surface 1 and sandwiching and holding the wiring is formed integrally with the housing surface 1 and the clamp portion 2 is opened. And the stopper portion 3 disposed at a position where the clamp portion 2 contacts within the elastic limit of the root portion 211 of the clamp portion 2. It is possible to prevent (clamp part 2) from being damaged.

In the above description, as shown in FIG. 1, the support portion 21 of the clamp portion 2 is configured to extend in a direction perpendicular to the housing surface 1, and the stopper portion 3 is provided so as to protrude from the housing surface 1. Indicated. However, the shape of the clamp part 2 and the stopper part 3 is not limited to this, and the clamp part 2 is configured to be able to sandwich and hold the wiring. When the clamp part 2 is opened, the clamp part 2 What is necessary is just the structure arrange | positioned in the position where the said clamp part 2 contacts within the elastic limit in the 2nd root part 211. FIG.
For example, in FIG. 2, an opening is provided in the housing surface 1, and the support portion 21 is configured to extend in the horizontal direction with respect to the housing surface 1 in this opening. Further, the side wall portion of the opening facing the support portion 21 is used as the stopper portion 3. Moreover, in the example of FIG. 2, the contact ridgeline 213 of the clamp part 2 and the contact surface 32 of the stopper part 3 contact.

  Further, in the present invention, any constituent element of the embodiment can be modified or any constituent element of the embodiment can be omitted within the scope of the invention.
