Zero-power-consumption starting protector for refrigeration compressor

Abstract

A zero-power-consumption starting protector for a refrigeration compressor comprises the components of a housing, wherein the left side of the housing is provided with a starter base and the right side is provided with a starting control mechanism chamber and a zero-power-consumption starting mechanism chamber; a protector which is arranged in a protector accommodating chamber; a starting control mechanism and a zero-power-consumption starting mechanism; a protector connector, an L connector, a grounding connector and an N connector; and a housing cover. The zero-power-consumption starting protector is characterized in that the zero-power-consumption starting protector further comprises an S lead-out pin and an M lead-out pin which are arranged on the housing; the S lead-out pin is connected with the zero-power-consumption starting mechanism; the M lead-out pin is connected with the starting control mechanism; the protector connector is provided with protector connector insertion pieces; the L connector is provided with L-shaped connector insertion pieces; the grounding connector is provided with grounding connector insertion pieces; the S lead-out pin is provided with an S lead-out pin insertion piece; the M lead-out pin is provided with an M lead-out pin insertion piece; the N connector is provided with a set of N connector insertion pieces; and the set of N connector insertion pieces faces a front portion. The zero-power-consumption starting protector has advantages of high assembling efficiency, effective insurance for high safety, and high speed in connecting an operating capacitor with a circuit.

Description

technical field [0001] The invention belongs to the technical field of motor starting and protection devices for refrigeration compressors, and in particular relates to a non-power consumption starting protector for refrigeration compressors. Background technique [0002] In the published Chinese patent literature, there is no lack of technical information about the non-power consumption start protector of refrigeration compressors, such as CN104734428A (no power consumption and energy saving single-phase AC motor starter with improved structure) and CN104734570A (no power consumption and energy saving Type single-phase AC motor starter protector) and so on. [0003] The non-power consumption starting protectors of refrigeration compressors in the prior art, including the above-mentioned patents, generally have the following deficiencies: First, because the protector connectors, L connectors, and ground connectors arranged on the housing The orientation of the connecting pi...

Problems solved by technology

[0003] The non-power consumption starting protectors of refrigeration compressors in the prior art, including the above-mentioned patents, generally have the following deficiencies: First, because the protector connectors, L connectors, and ground connectors arranged on the housing The orientation of the connecting piece and the N connecting piece is inconsistent, so it is more troublesome in the process of assembling with the refrigeration compressor, which is not conducive to improving the assembly efficiency, and because the orientation of the connecting pieces is different, the compressor is required to provide enough assembly space; its Two, due to the different orientations of the aforementioned connectors, after the line connection is completed, the safety is affected due to the messy lines; third, due to the different orientations of the connectors, there is also a corresponding impact on the assembly efficiency in the production process. Fourth, due to the limitation of structural design, it is not convenient to connect the running capacitor to the circuit conveniently and quickly

[0004] According to the applicant's analysis, the reason why the directions of the aforementioned connectors on the housing are different is because of the restriction of the installation space provided by the refrigeration compressor, in other words, the restriction of the size of the housing in the longitudinal direction. The same side of the shell with a limited length cannot arrange all the connecting parts one by one, and can only be distributed on different sides of the shell, unless the dimension of the length direction of the shell is expanded, but when the dimension of the length direction of the shell is expanded, it will be Will be rejected by the reserved space of the refrigeration compressor
