Abstract

PROBLEM TO BE SOLVED: To provide a cable clamp of which a cross section is an U-shaped, which has a high intensity.SOLUTION: A cable clamp 2 is comprised to an electric device having a jack part. The cable clamp has an almost U-shaped form, and is formed by: a fixing part 4 and a clamp part 6 which can hold a cable 3a having a plug part connected to the jack part; and a bend part 5 coupling the fixing part 4 and the clamp part 6. The bend part 5 has a bent part 5a and a non-bent part. The clamp part 6 allows the cable to be inserted and extracted when the bent part 5a is elastically deformed to a separating direction from the fixing part 4. The bend part 5 includes: a first abutment 8 extended to a connection line direction of the almost U-shaped form; and a second abutment 9 in which a direction opposite to the first abutment 8 and a central axis are approximately match, and that is projected from the bend part 5.SELECTED DRAWING: Figure 3

Description

  The present invention relates to a cable clamp for holding a cable.

  Conventionally known cable clamps have a U-shaped cable holding groove formed by a support substrate and a cable holding plate, as described in Patent Document 1. And the retainability of a cable is improved by giving urging | biasing force from a cable holding plate to a support substrate side using spring steel.

JP 2013-42601 A

  However, since the conventional cable clamp has a structure in which the cable holding groove is formed in a U-shaped cross section and is urged by spring steel, the cable holding groove is deformed or damaged after being opened to some extent in the direction in which the holding groove opens. There was a problem in strength such as In addition, the structure was also vulnerable to external impacts, and was also susceptible to deformation and breakage. Therefore, the actual situation is that provision of a higher-strength cable clamp is required.

  The present invention has been proposed in order to solve the above-described problems of the prior art, and an object of the present invention is to provide a cable clamp with higher strength and a simple structure compared to the prior art.

In order to achieve the above object, a cable clamp according to the present invention comprises:
In a cable clamp that is provided in an electronic device having a jack portion and can hold a cable having a plug portion connected to the jack portion,
A substantially U-shaped cable clamp comprising a fixed part and a clamp part, and a curved part connecting the fixed part and the clamp part,
The bending portion has a bending portion and a non-bending portion, and the clamping portion enables insertion and removal of a cable by elastically deforming the bending portion in a direction away from the fixing portion.
The curved portion has a first abutment extending in a tangential direction of a substantially U shape,
The second abutment has a direction opposite to the first abutment, a center axis that is substantially the same, and a protrusion from the curved portion.

  According to the present invention, a cable clamp having a higher strength can be provided in a cable clamp having a U-shaped cross section.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

(Description of appearance of imaging device)
FIG. 1 is a perspective view showing an example of the appearance of an imaging apparatus 1 according to an embodiment of the present invention.

  As shown in FIG. 1, the imaging device 1 includes a cable clamp 2, and the cable clamp 2 holds a cable 3 a of a plug 3 connected to the imaging device 1.

(Description of cable clamp configuration)
2a and 2b are perspective views shown for explaining the configuration of the cable clamp 2. FIG.

  The cable clamp 2 includes a fixed portion 4 and a clamp portion 6, and a curved portion 5 that connects the fixed portion 4 and the clamp portion 6, and is generally a U-shaped cable clamp. Moreover, the bending part 5 is comprised by the bending part 5a and the non-bending part 5b.

(Explanation of butting at the curved portion of the cable clamp according to the present invention)
FIG. 3 illustrates a state in which the cable 3 a is inserted into the cable clamp 2 attached to the imaging device 1.

  The cable clamp 2 is a part formed of a material such as POM or 66 nylon which is easily elastically deformed. The clamp portion 6 is formed by elastically deforming the bent portion 5a in the bending portion 5 in the direction away from the fixing portion 4, thereby the cable 3a. The cable 3a is held in the cable holding groove 7a by urging the clamp portion 6 toward the fixed portion. Here, when the clamp part 6 is deformed in a direction away from the fixed part 4 with a certain load or more, there is a possibility that the bent part 5a exceeds the elastic region, causes plastic deformation, and then breaks. Therefore, as shown in FIG. 3, the cable clamp 2 according to the present invention has the first abutting 8 extending in the tangential direction of the substantially U shape on the curved portion 5, so that the bent portion 5a is excessively deformed. In this case, the bent portion 5a is prevented from causing plastic deformation or breakage when the first abutment 8 abuts against the exterior of the imaging device.

  Further, as shown in FIG. 3, the bending portion 5 has a second abutment 9 which is opposite to the first abutment 8 and whose center axis substantially coincides and protrudes from the bent portion 5 a of the bending portion 5. Thereby, since the impact from the outside is applied to the second abutment 9 before being transmitted to the bent portion 5a, the bent portion 5a can be prevented from being damaged.

(Description of the arrangement of the first butting and the second butting)
In FIG. 4, the perspective view of the cable clamp 2 for demonstrating arrangement | positioning of the 1st butting | fastening 8 and the 2nd butting | wearing 9 is shown.

  4, 2 is a cable clamp, 4 is a fixing part, 6 is a clamping part, 5 is a bending part, 5a in the bending part 5 is a bending part, and 5b is a non-bending part. Further, 8 is a first butting and 9 is a second butting. Here, as shown in FIG. 4, the first butting 8 and the second butting 9 are arranged in the non-bent portion 5 b. Thereby, the strength of the cable clamp 2 can be increased effectively without impairing the flexibility of the bending portion 5.

(Description of cable holding groove in cable clamp)
FIG. 5 illustrates a state in which a plurality of cables 3 a and 3 b having different thicknesses are inserted into the cable clamp 2 attached to the imaging device 1.

  Here, the cable clamp 2 according to the present invention has a plurality of cable holding grooves 7a and 7b having different curvatures. Accordingly, the cables 3a and 3b having different thicknesses can be placed and held in the cable holding grooves 7a and 7b.

(Explanation of arrangement of screw fastening part and positioning part in fixed part of cable clamp)
FIG. 6 is a perspective view of the cable clamp showing the arrangement of the screw fastening portion and the positioning portion in the fixing portion of the cable clamp.

  Here, 4 is a fixing portion, 10 is a screw fastening portion, 11 is a positioning portion, and 12 is a fixing screw. The positioning portion 11 included in the cable clamp 2 is inserted into a positioning hole provided in the imaging device 1 (not shown) and fixed to the imaging device 1 by the fixing screw 12, so that the position with respect to the imaging device 1 is regulated. Here, the fixing portion 4 has a positioning portion 11 at a symmetrical position with respect to the screw fastening portion 10. Thereby, even if the cable clamp 2 is rotated 180 °, it can be fixed to the image pickup apparatus 1 and the convenience for the user can be improved.

  As described above, the present invention has been described in detail based on the preferred embodiment. However, the effect of the present embodiment can provide a cable clamp with higher strength in a cable clamp having a U-shaped cross section.
