Description

Technical Field

[0001] The utility model relates to refrigeration equipment, in particular to a wire harness sealing structure of refrigeration equipment, belonging to the technical field of wire harness sealing of refrigeration equipment. Background Art

[0002] The temperature inside the refrigeration equipment cabinet is low, while the temperature outside the cabinet is normal. Leakage caused by poor sealing will affect the refrigeration efficiency, thereby increasing energy consumption. At the same time, large temperature differences are prone to condensation, which will reduce insulation and increase electrical safety risks. If chemicals are used to increase sealing, it is not conducive to environmental protection.

[0003] Refrigeration equipment of different specifications have different electrical connections. Therefore, equipment of the same specifications and sizes have different wiring harness configurations. The same wiring harness sealing structure needs to be flexible and applicable to multiple configurations. Since there are many different applications for wiring harnesses in the cabinet, the wiring harness specifications of the same equipment are diverse, including various voltages, currents, wire diameters, etc. In order to meet electrical safety and convenient wiring, it is necessary to distinguish between high-voltage, low-voltage and communication lines, and divide the wiring harness into multiple paths. Since the wiring harness distinguishes between outside and inside the cabinet, it is required to be able to be quickly plugged in and out for production and transportation.

[0004] The existing connectors on the market do not have additional protection, cannot solve the temperature difference problem, and will cause condensation. In addition, due to the size and type of the connector, the number and types of wire harnesses that can be fixed are small, which is difficult to meet the actual use needs. The use of through holes and chemical glue can improve the sealing performance, but it is not removable and cannot be plugged in, making later maintenance difficult. In the process of chemical manufacturing and use, environmental pollution will increase, which is not conducive to environmental protection. Therefore, in response to the above problems, a wire harness sealing structure suitable for refrigeration equipment is proposed. Utility Model Content
