Description

Cable Guide {A CABLE GUIDE}

The present invention relates to a cable guide, and more specifically, to a connection terminal provided on one side of a control device such as a programmable logic controller (hereinafter referred to as a PLC) for use in automatic control and monitoring of an industrial plant. The present invention relates to a cable guide for holding a cable for wired connection between a connection terminal of an automation device to be controlled while having a predetermined radius of curvature.

Recently, a control device such as a PLC that performs automatic control and monitoring through data communication by connecting a plurality of automation devices by wire is widely used.

The control device and the automation device communicate data between a connection terminal provided on one side such as the side or front of the control device and a connection terminal provided on one side of the side or the front of the automation device for the convenience of execution and movement of the automation device. Frequently, the cable for the cable is bent in a bent state.

However, recently, optical cables are mainly used as such cables. In the case of such optical cables, they must be connected to both connection terminals in a bent state while securing a minimum radius of curvature for preventing attenuation or damage.

However, in the actual industrial field, such a minimum radius of curvature is not secured, or a cable having a weak strength may be damaged by collision with a flow or an operator due to the operation of an automation device, or the communication signal quality may be degraded.

In order to prevent such a problem, a "cable guide" proposal of Korean Patent Laid-Open Publication No. 10-2009-0045144, which is a patent document of the prior art document, which will be described later, is proposed.

The prior art “cable guide” has a curved and elongated body portion 4 as shown in FIGS. 1 to 6 of Korean Laid-Open Patent Publication, and a boot holder at a connection terminal side end of the body portion 4. (bootholder) 6 and the cord holder 8 are provided in the other end side, respectively. The boot portion of the optical fiber cable is held by the boot holder 6, the cord portion by the cord holder 8, and the cord portion located between each holder 6, 8 follows the curved shape of the body portion 4 You will be guided. The main body portion 4 is formed in the innermost of the plurality of optical fiber cables connected to the connecting terminal, the optical fiber cable that is maintained in the most bent state of curvature radius is not smaller than the minimum bending radius, that is to form a curvature radius of the same or larger do.

To install and fix an optical fiber cable in such a "cable guide", the cable guide (between the cords 20a and 20b) of the two-core one set optical fiber cable 20 connected at the plug portion as described in the identification number <32>. 2) is arranged, and the cords 20a and 20b are inserted into the respective hollow portions of the inner diameter A of the boot holder 6. And the cable guide 2 is moved to the plug side suitably. Then, the cord 20 is moved to an appropriate position such as near the shrinkage tubes 20c and 20d, and the cords 20a and 20b are inserted into the cord holders 8, respectively. In addition, the boot holder 6 of each cord 20a, 20b and the central portion of the cord holder 8 must be pushed in such a way that they are held by the jaws 16a, 16b.

However, the "cable guide" according to the prior art is not only troublesome and inconvenient to install and fix the optical fiber cable, but also to shrink the cords 20a and 20b, as shown in FIG. Since the tube 20c and 20d and the plug side portion must be configured to increase discontinuously, there is a problem in that the manufacturing cost of the optical fiber cable is increased and manufacturing efficiency is lowered.

In addition, even if the cords 20a and 20b are bent and accommodated in the cord holder 8, the lower portion thereof does not have a separate fixing means, so the lower portion of the optical fiber cable flows or collides with an operator to secure a minimum radius of curvature. Is not guaranteed, and a problem arises that the signal quality is broken or the communication signal is degraded.

The body part 100 is a pair of cables, one end of which is open so that the central portion of the cable 10, one end of which is connected to at least one connection terminal (not shown) provided on one side of the control device (not shown), is bent and received. Receiving groove 110 is formed.

The plug holder 200 is integrally formed at one end of the body part 100, and one side of the plug holder 200 is connected to one end of the cable 10 to receive and couple a pair of cable plugs 20 connected to the connection terminal of the control device. A pair of open plug holder accommodating grooves 210 are formed. As such, in the present embodiment, since the cable plug 20 that is not the end of the cable 10 can be directly coupled to the plug holder 200 at one time, the receiving coupling of the cable 10 is very simple compared to the past.

Then, the cable 10 is accommodated in the cable receiving groove 110 of the body part 100 and the cable 10 is applied to the side that is open to the first cable holder 300 and the second cable holder 400. If the cable is accommodated, the cable 10 can be easily received and coupled to the cable guide.

According to the cable guide according to the present invention as described above, by using the plug holder 100, the first cable holder 300 and the second cable holder 400 easily and simply fix the cable 10 to have a predetermined radius of curvature. Not only can it be installed, but also the structure of the cable 10 to be installed can be simplified compared to the prior art has an advantageous effect that can reduce the manufacturing cost of the cable 10 and improve the manufacturing efficiency.

In addition, according to the cable guide according to the present invention, the middle portion of the cable 10 that can not be fixed by the conventional cable guide can also be fixed through the second cable holder 400 and the connecting portion 500 of the minimum radius of curvature Not only is it easier to secure, there is an advantageous effect that can prevent the flow of the middle portion of the cable 10 and the damage caused by collision with the operator and the degradation of the communication signal quality.
