[Technical field to which the invention belongs]

 The present invention relates to a waterproof type corrugated tube fixing connector, and more particularly to a waterproof type corrugated tube fixing connector for fixing a bellows tube for holding a cable to equipment or general equipment and providing a fixing head for connecting the cable. .

[0002]

[Prior art]

 A cable connector is a connecting part dedicated to a cable, and its main use is as a cable bundling or a tubular article, which can be connected to an article to be fixed, and pulls a cable or a tubular article to the article to be fixed. .

[0003] US Patent No. 5,927,892 entitled "DEVICE FOR FASTENI NG A CABLE TO A BOARD" shows the structure of a cable fixing connector, and FIG. 1 shows another known structure. It is shown. As shown in the figure, the cable connector includes a main body 10 having external threads formed at both ends, a nut 11 screwed to the main body 10 and connecting the main body to an article to be fixed, and a joint surface between the nut and the main body. A packing 15 interposed therebetween, a holding claw portion 12 provided at the other end of the main body, a cable holding ring 13 fitted in the holding claw portion, and an end provided with the holding claw portion and the cable holding ring of the main body. And a fastening part 14 to be screwed to the part. With this configuration, the cable 20 penetrating the main body is bound via the cable holding ring after receiving the pressure, and the cable is fixed to the fixed article 30 with the fixing connector.

[0004] In the above-described method of bundling a cable using a fixed connector, the holding claws are composed of a plurality of elastic claws 121 having an appropriate gap therebetween, and the claws form an inner edge of a tightened part. After compressing the inner slope, the outer edge of the cable is bound to the cable holding ring. After the claws have shrunk and clamped, there is an additional gap between each other, which provides the cable with a slightly pointed scissoring relationship with the claws. For this reason, when the cable receives relatively large rotational power or tensile force due to the lack of the pinching and binding force of the claws (see FIG. 2), the cable may be damaged due to the lack of the pulling resistance of the clamp. The cable is pulled and moved, and sometimes the cable clamp ring is also pulled out and detached from the body. In addition, once the cable is pulled, there is a problem that a gap is instantaneously generated at the position A shown in the figure, and the passage becomes a path through which moisture soaks.

【Example】

 As shown in FIGS. 3 and 4, the waterproof type corrugated tube fixing connector of the present invention is composed of the following several unit components. It includes a screw head 10, a nut 20, a clamping nut 30, an elastic clamping ring 40 and a corrugated tube 50. The above-mentioned screwing head 10 is formed in a tubular body, provided with an axial hole 11 in the axial direction, formed with threads 12, 12 'on the outside, and formed with a stopper block 13 at the middle position. 2, 12 'are divided into both front and rear portions, and are used for screwing the nut 20 and the tightening nut 30 together. That is, the nut 20 and the tightening nut 30 have female threads 21 and 31 respectively matching the threads 12 and 12 ′ formed at one end of the screw connection head 10, wherein the nut 20 is a commonly-used annular body. Then, the screwing head 10 is combined with the stopper block 13 to clamp the screwing head 10 to the article 60 to be fixed. During the operation, a packing 80 made of rubber or soft plastic is fitted therebetween, and the packing 80 is sandwiched between the stopper block 13 and the fixed article 60 to provide a sealing effect.

The tightening nut 30 is a tightening means that is screwed to the screwing head 10, is provided with a through hole 32 through which the cable 70 penetrates in the axial direction, and is coaxially formed on the inner wall surface of the through hole 32. A female screw 31 screwed into the female screw 31 and an inclined inner surface 33 connected to the end of the female screw 31 are provided.

The main purpose of installing the slant guide surface 33 of the through hole 32 of the tightening nut 30 is to use the slant guide surface 33 by changing the screwing depth of the tightening nut 30 to the screwing head 10. The purpose is to compress and contract the elastic holding ring 40 to obtain a convergence effect. As shown in the figure, the elastic clamping ring 40 is a hollow ring formed on the end where the tightening nut 30 of the screwing head 10 is screwed, and is made of a soft rubber material or an elastic plastic material. Similarly, in the axial direction, a perforation 41 for penetrating the cable 70 is provided, and a fitting portion 42 inserted into the shaft hole 11 due to a difference in form is formed. And an annular receiving cone surface 431 is provided on the outer edge of the holding portion 43, and this receiving cone surface 431 is screwed into the screwing head 10 of the tightening nut 30 described above. When the depth is changed, the diameter of the perforation 41 is changed by receiving different degrees of pinching and binding force of the inclined guide surface 33. Thus, when the cable 70 passes through the elastic holding ring, the cable 70 penetrates the holding and binding of the elastic holding ring 40, and the outer edge of the cable 70 is pressed by holding, so that the cable 70 cannot be relatively slid.

In this embodiment, in order to surely enhance the waterproof effect, the elastic clamping ring 40 clamps and binds not the cable 70 but the corrugated tube 50 provided around the outer edge of the cable 70. Please refer to FIG. The corrugated tube 50 effectively protects the cable 70 from contact with moisture, and the corrugated tube 50 is provided with a corrugated pattern in which the outer edge of the corrugated tube 50 is alternately provided. A rib 44 is provided on the inner edge of the corrugated tube 50 so as to correspond to the concave groove 51 on the outer edge of the corrugated tube 50, and extends inwardly with the stopper 45 in the perforation 41 of the elastic holding ring. The depth of entry into the perforations 41 is limited. As a result, the elastic clamping ring 40 penetrates the fastening nut 30 to clamp and bind the corrugated tube 50, and also allows the rib 44 to penetrate the tight fitting of the rib 44 into the concave groove 51, thereby providing good waterproofness, good adhesion, It provides three effects of preventing movement due to vibration, and does not generate a sliding phenomenon with the elastic holding ring 40 even when the corrugated tube 50 is pulled, and moisture outside the fixed article 60 elastically clamps with the corrugated tube 50. The ring 40 is prevented from entering the other side from the joint surface. For this reason, the present invention is surely enhanced in functionality as compared with the cable tying structure using the rigid pinching claws employed in the traditional connector.

The above is only a description of preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modification or alteration of details that can be made based on the present invention is not limited to the present invention. Shall belong to the claims.
