Abstract

The invention relates to a monitoring system with control of a refrigeration container and a refrigeration container connection socket box. A connection cable is connected to the compatible plug-in port commonly formed in refrigeration containers. The connection socket box connecting connection cables is used to collect the state information of each refrigeration container transferred to a management server, so that a monitoring system applicable to all kinds of refrigeration container is provided, and can transfer a control signal for the refrigeration container through the compatible plug-in port, thus making it possible to remotely control the refrigeration container. Hence the system is simplified so as to reduce the cost and improve the stability of the system. The function of monitoring the state information and the function of measuring the power consumption of the refrigeration container are also provided so as to reasonably calculate the cost of the actual power consumption.

Abstract

The present invention provides an end packing for a multi-cable transit for shielding electromagnetic waves so as to completely seal an internal space of a multi-cable, wherein the internal space of the multi-cable is completely sealed by rotating a screw means in a corresponding location to move a rear tension wedge in the forward and backward directions when the internal space of the multi-cable transit is not sealed by forming the number of rear tension wedges corresponding to the number of through-holes of a front tension wedge into which the screw means is inserted, so as to be configured to form one rear tension wedge corresponding to one screw means. In addition, the present invention provides the end packing for the multi-cable transit for shielding the electromagnetic waves, which can efficiently maintain the assembled shape without a change in the entire size and volume of the end packing by preventing separation of an upper pressing wedge and a lower pressing wedge due to an elastic member so as to efficiently maintain the assembled shapes of the front tension wedge, the rear tension wedge, the upper pressing wedge, and the lower pressing wedge, be easily inserted into a frame, easily disassemble the end packing when implementing a maintenance, a management or a rework, simplify an assembling structure and reduce a manufacturing time and an error rate for the end packing by inserting a screw-shaped sleeve supported by an insertion of the screw means inside the front and rear tension wedges, and enables easy treatment of maintenance, management, transportation and the like for the end packing. The end packing for the multi-cable transit for shielding the electromagnetic waves according to the present invention comprises: the front tension wedge and the rear tension wedge which face each other and move in the front and rear directions by the rotation of the screw mean; the upper pressing wedge and the lower pressing wedge which face each other and are located at upper and lower sides of the front tension wedge and the rear tension wedge so as to move in the upper and lower directions according to the front and rear movements of the front tension wedge and the rear tension wedge; and an elastic member for preventing the separation of the upper pressing wedge and the lower pressing wedge from the upper and lower sides of the front tension wedge and the rear tension wedge.

Abstract

The present invention provides a cable sealing system for electromagnetic shielding, which prevents the malfunction of electronic devices, control systems, and the like by absorbing and blocking electromagnetic waves radiated from a cable passing through a center hole of a body, and which seals the cable passing through the center hole of the body. Specifically, the present invention is capable of primarily blocking electromagnetic waves by an insert block mounted in a center hole of a body and discharging the electromagnetic waves of the cable that are radiated through the insert block to the outside by using a shielding sheet, and sealing and pressing the insert block and the cable mounted in the cable by enabling the body to be compressed by a compression member through a fastening operation of a fastening member. In addition, the present invention can be easily mounted in a small hole, a through body or the like, and can reduce costs for sealing a small number of cables. The cable sealing system for electromagnetic shielding, according to the present invention, comprises: the body which has a center hole which can be penetrated from one side to the other side such that a cable can pass therethrough and comprises a front body and a rear body that are formed to contact each other; the insert block which is mounted in the center hole of the body, positioned on and below the cable, and encloses the cable so as to block the electromagnetic waves radiated from the cable; the shielding sheet into which the insert block is inserted, and which is located between the front body and the rear body to block electromagnetic waves radiated from the cable through the insert block; the compression member mounted on both sides of the body and disposed around the center hole of the body to compress the body; and the fastening member for fixing the compression member by passing through the body.
