Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a fully sealed rubber sleeve structure of a compressor terminal. Background Art

[0002] At present, the air-conditioning field is subject to environmental protection and decarbonization requirements. More and more air-conditioning heat pump products use flammable refrigerants such as R32 / R290 as circulating working fluids. When using such refrigerants, safety is particularly important. At the product development and design end, it is necessary to consider preventing flammable refrigerants from coming into contact with ignition-prone devices. For conventional compressor terminal components, including terminal blocks (with card-type or threaded connections, etc.), terminal box fixing studs, terminal box fixing nuts, and terminal box housings.

[0003] This type of conventional design (such as the one in the instruction manual) Figure 1 While these products offer some protection against dust and water, the wide opening at the junction box's wire entry and the generally rigid structure of the box's housing also create a poor seal with the compressor's exterior. Consequently, they cannot effectively prevent refrigerant leaks from reaching the terminals. If these products are used in flammable refrigerant systems, the sealing structure of the junction box terminals needs to be improved. Furthermore, consideration must be given to the safety of the heat generated by the wires when fully sealed, as this poses a fire risk. Utility Model Content

[0004] The main purpose of the utility model is to provide a fully sealed rubber sleeve structure for compressor terminals, aiming to solve the technical problems that the sealing measures of traditional compressor terminals are not perfect and are easily affected by the external environment. For example, impurities such as moisture and dust may invade the interior of the compressor, causing electrical failure or reducing the service life of the compressor, and preventing external flammable refrigerant gas from entering the compressor terminals, creating a risk of ignition.

[0005] In order to achieve the above-mentioned purpose of the utility model, the first aspect of the utility model proposes a fully sealed rubber sleeve structure for a compressor terminal, including a terminal, a terminal box cover fixing bolt column, a terminal box cover fixing bolt column locking nut, a terminal box cover and a fully sealed rubber sleeve; the fully sealed rubber sleeve includes a fully sealed rubber sleeve wire hole for passing the compressor power cord, and one end of the compressor power cord is fixed on the terminal.

[0006] Furthermore, the fully sealed rubber sleeve passes through the fully sealed rubber sleeve bolt column through the junction box cover fixing bolt column and is sleeved on the wiring terminal;

[0007] Furthermore, the junction box cover is fixed on the fully sealed rubber sleeve base by passing through the junction box cover fixing bolt column, and the edge of the fully sealed rubber sleeve base completely wraps the bottom edge of the junction box cover with a margin;

[0008] The locking nut of the junction box cover fixing bolt column is fixed on the junction box cover fixing bolt column to form a tightening and sealing state.

[0009] Furthermore, the power cord of the compressor passes through the wire hole of the fully sealed rubber sleeve and is tied tightly with a binding tape, and can be further sealed by applying glue.

[0010] Furthermore, the fully sealed rubber sleeve is made of soft rubber material.

[0011] Furthermore, the gaps in the fully sealed rubber sleeve structure are sealed by adding sealant.

[0012] Furthermore, the fully sealed rubber sleeve is provided with a fully sealed rubber sleeve exhaust port, and a fully sealed rubber sleeve exhaust port rubber plug is provided on the fully sealed rubber sleeve exhaust port.

[0013] Furthermore, when the internal pressure of the vent rubber plug of the fully sealed rubber sleeve exceeds a set threshold, it can be separated from the vent outward, but cannot be separated inward.

[0014] Furthermore, the fully sealed rubber sleeve exhaust port rubber plug is used to discharge the bad air pressure in the sealed rubber sleeve while keeping the external airflow from entering the sealed rubber sleeve.

[0015] Furthermore, the fully sealed rubber sleeve is installed in the existing compressor terminal cover structure without the need to cover the compressor end cover externally.

[0016] Beneficial effects:

[0017] 1. The utility model adds a fully sealed rubber sleeve structure and seals the power cord through-hole by means of binding with a band and applying glue, thereby effectively preventing impurities such as gas, moisture, and dust from entering the interior of the compressor and enhancing the sealing performance of the terminal area. The fully sealed rubber sleeve structure design can be directly installed in the existing compressor terminal cover structure without the need for an additional external sleeve to cover the compressor end cover, simplifying the installation process, reducing installation costs, and facilitating daily maintenance and repair work.

[0018] 2. The utility model sets an exhaust port through a fully sealed rubber sleeve and is equipped with an exhaust port rubber plug. When the internal pressure exceeds a certain threshold, the rubber plug can automatically detach from the exhaust port to effectively discharge the internal bad gas (refrigerant leaked from the terminal), while preventing external flammable refrigerant from entering the sealed rubber sleeve, eliminating the possibility of external flammable refrigerant contacting the terminal, and ensuring its safety and reliability.

[0045] In this embodiment, the design of the fully sealed rubber sleeve exhaust port plug 605 can effectively prevent external gas (such as flammable refrigerant) from entering the sealed rubber sleeve, eliminating the possibility of external flammable refrigerant contacting the wiring terminals, and ensuring its safety and reliability.

[0046] In one embodiment, the fully sealed rubber sleeve 6 is installed in the existing compressor terminal cover structure without the need to cover the compressor end cover externally.

[0047] In this embodiment, the fully sealed rubber sleeve 6 is directly installed in the existing compressor terminal cover structure, without the need for an additional external sleeve to cover the compressor end cover, which simplifies the installation process and facilitates daily maintenance and repair work.

[0048] Among them, the fully sealed rubber sleeve 6 includes a fully sealed rubber sleeve wire hole 603, and the power cord of the compressor 1 passes through the fully sealed rubber sleeve wire hole 603 and is connected to the terminal 2. After the power cord passes through the wire hole, it is tied tightly with a strap to reduce the gap between the power cord and the wire hole.
