Description

Report of the Invention Patent for "COMBOMODULAR PROTECTION AND DEPARTURE FOR REFRIGERATION HERMETIC COMPRESSOR".

The present invention relates to a modular start-up combo for airtight refrigeration compressor, requiring a smaller tooling to produce various combo configurations, compared to the prior art, as well as the use of a simpler tooling and consequent cost reduction for the installation. development of such settings.

Description of the prior art

The protection and starter combo is a product that groups the starter relay and overload protector functions into a single set.

Combos are currently built so that each function is an integral part of the combo and cannot be decoupled.

In this sense, each function is merged into the bodies we make combo. Therefore, for different combo configurations, different molds are required. Current systems have the following disadvantages:

- High tooling cost for each type of configuration as it requires specific tooling (mainly injection molds) for each type of configuration;

- The over-molding technique is not viable due to the complexity of plastic injection molds. Overmolding, in some cases, could bring cost savings.

- Higher component inventory cost due to the complexity of plastic components.

Thus, the present invention offers an innovative solution for the hermetic compressor protection and starting combo, compared to the previous techniques, providing a system that makes use of a simpler and less expensive tool.

Purpose of the Invention

The aim of the present invention is to propose a modular start-up and start-up combo for airtight refrigeration compressor, requiring a smaller tooling to produce many different configurations compared to the previous techniques, as well as the use of a simpler tooling and consequent reduction of costs for the development of detailed configurations.

Brief Description of the Invention

The object of the present invention is achieved by providing a refrigeration hermetic compressor protection and starting combo comprising at least one motor starting device and at least one motor overload protection device, the The motor starter being releasably associated with the overload protection device, the protection and starter combination is associable by at least one hermetic compressor power terminal, characterized by being releasably associable with at least one electrical connector platform, the combo being seatable with at least one cable gland.

Detailed Description of the Figures

As mentioned earlier, prior art solutions for hermetic compressor starting and protection combos today present a number of disadvantages regarding the tools required and the high costs involved.

Figures 1 to 6 show the possible embodiments for the proposed modular module.

The protection and starting combo for hermetic cooling compressor 1, object of the present invention comprises at least one motor starting device 2 and at least one motor overload protection device 3.

The motor starter 2 (starter relay) fits neatly into the overload protection device 3. The starter and starter combo 1 is assignable to at least one hermetic compressor power supply terminal, and it is releasably assignable. at least one platform of electrical connectors.

Combo 1 is pluggable to at least one cable gland 30, as illustrated in detail in Figure 5. Combo1 is associable to at least one side electrical connector platform 10.

The combo, according to the teachings of the present invention, is associable with at least one front electrical connector platform 20, and it is still dockable with a support base 40.

The support base 40 is associated with an airtight compressor housing.

The present combo 1 may be further engageable with a lid 50, as illustrated in detail in FIG. 6.

Finally, from the present solution, the combo can be formed by combining several modules, as listed below: a) basic protection and starting combo (various protection and starting models can be employed (4TM, 4MP, WMP, etc.);

b) front access connector platform;

c) side access connector platforms;

d) cable glands;

e) fence; and

f) cap.

In addition, this combo offers as advantages, compared to previous techniques the following characteristics:

a) smaller tooling to produce various configurations of the color;

b) simpler tooling to produce more complex combos;

c) simpler discrete components allow for over-molding to achieve cost savings;

d) enables great variability of configurations at lower cost;

e) inventory cost reduction due to lower number of i-tens and lower complexity of discrete items.

Finally, for the proposed combo, it is found that the same is slidably associable with the late-riser electrical connector platforms 10 or the front-connector electrical platforms 20.

Having described examples of preferred embodiments, it should be understood that the scope of the present invention encompasses other possible variations and is limited only by the content of the appended claims, including the possible equivalents thereof.
