Description

Technical Field

[0001] The invention relates to a weight-starting thermal protector and an assembly method and an installation method thereof, in particular to a multi-terminal weight-starting thermal protector. Background Art

[0002] The heavy hammer starter thermal protector is assembled from a thermal protector 1, a heavy hammer starter 2, and a bracket 3. It is installed on the refrigerator compressor and is used to start the refrigeration compressor and protect the compressor from overcurrent and overtemperature. In view of this, a multi-terminal heavy hammer starter is disclosed in the patent document with application number 202223330017.2. In the above-mentioned prior art, ① the moving and static contacts are riveted. Due to the difference in contact size, the consistency of riveting strength is poor, resulting in poor contact resistance consistency, easy to generate heat, and reduce the life of the contact. ② The contacts are manually riveted, which has low production efficiency.

[0003] The conventional installation method of compressor starters and thermal protectors on the market is: first insert the thermal protector 1 and the heavy hammer starter 2 into the sealed terminal 4 of the compressor 5 (the thermal protector pin is inserted into the first terminal 4-1 of the compressor 5, and the S end and the M end of the starter are respectively inserted into the second terminal 4-2 and the third terminal 4-3 of the compressor 5), and the starting capacitor Cs is connected in series between the second connecting plug of the starter and the N4 end of the N end plug of the starter. In particular, the power line connection of the refrigerator temperature controller, the indicator light, etc. needs to be electrically connected by using the thermal protector and the starter connection terminal, and then the plastic cover 7 is inserted, and finally the plastic cover 7 and the compressor mounting bracket 6 are fixed by snapping; as the volume of the compressor 5 continues to shrink, the space of the plastic cover 7 for installing the thermal protector 1 and the heavy hammer starter 2 is also reduced, and the additional electrical connection (such as: the electrical connection of the power line of the refrigerator temperature controller, the indicator light, etc.) will make the wiring inside the plastic cover 7 chaotic, there are safety hazards and the installation efficiency is low (such as Figure 1 , 2 as shown).

[0004] In actual use, there are still the following defects: 1. The power neutral line, refrigerator temperature controller, and indicator light power connection need to be electrically connected at the thermal protector connection plug and the starter connection terminal. The internal wiring of the plastic cover 7 is confusing and the installation efficiency is low.

[0005] 2. Connecting the starting capacitor Cs in series between the second connecting plug of the starter and the N4 terminal of the N-terminal plug of the starter will also lead to confusion in the internal wiring of the plastic outer cover 7 and low installation efficiency.

[0006] 3. Since the refrigerator temperature controller, indicator light power connection terminal and starting capacitor Cs are provided, it is easy to cause safety hazards such as short circuit of the power line connection terminal, which may cause safety accidents in serious cases; since the refrigerator temperature controller, indicator light power connection and starting capacitor are additionally connected, the manufacturing space of the plastic cover 7 is increased, the manufacturing cost of the plastic cover 7 is increased, and the miniaturization design of the compressor is also affected.

[0007] 4. The movement is a key moving mechanism component inside the heavy hammer starter. In the existing technology, manual assembly and manual riveting are not only inefficient, but uneven force will also cause a certain proportion of springs and dynamic reeds to deform, the axis to bend, and other defective products to increase. Once it is put into use, it will cause quality problems such as jamming of movement components and poor contact of contacts. Summary of the invention

[0027] S3, placing the armature: the turntable continues to rotate, and when the turntable rotates the fixture for placing the moving plate and the spring to the second monitoring camera, the monitoring camera can be used to monitor whether the spring is placed in the fixture; The turntable continues to rotate. When the turntable rotates the fixture for placing the movable plate and the spring to the armature placement station, the armature is fed into the armature rail through the armature feeder and sent to the bottom of the armature claw. The No. 3 armature cylinder is pushed down by the No. 1 armature cylinder, and the armature claw is driven by the No. 3 armature cylinder to lock the armature. The No. 1 armature cylinder pulls the No. 3 armature cylinder up, and the No. 1 armature cylinder is pushed forward by the No. 2 armature cylinder, so that the armature is located above the material hole.

Since the diameter of the material tube is larger than the distance between the No. 1 movable clamp and the No. 2 movable clamp that clamps the movement assembly, the movement assembly will rely on its own gravity to fall into the material storage frame through the material tube when the No. 1 movable clamp and the No. 2 movable clamp are opened.

[0031] Furthermore, a technical purpose of the present invention is to provide an installation method for a heavy hammer starting thermal protector.

[0032] The above technical objectives of the present invention are achieved through the following technical solutions.

[0033] A method for installing a heavy hammer start thermal protector on a compressor, wherein the method is as follows: during installation, the heavy hammer start thermal protector is first directly plugged into the sealed terminal of the compressor, and the ground connection is made between the PE4 end of the plug-in and the bracket through the grounding end, and the PE2 end and the PE3 end of the plug-in are used for grounding conversion of other temperature controllers, indicator bulbs, etc.; Before the compressor is powered on, the heavy hammer starting thermal protector is in the normally open state. When the compressor motor starts, the starting current of the compressor main winding is large, the contact system is energized, and the compressor auxiliary winding is instantly connected, so that the compressor motor runs quickly. As the compressor speed continues to increase, the compressor main winding current drops rapidly, and the contact system is released and disconnected, so that the compressor motor enters the running state; In order to improve the starting performance and working efficiency of the compressor motor, a starting capacitor Cs is connected in series between the second connecting plug and the N4 terminal of the starter N-terminal plug, and a running capacitor Cr is connected in series between the starter pin and the N3 terminal of the starter N-terminal plug, and finally connected to the second terminal of the compressor auxiliary winding; The power supply is connected to the first plug of the thermal protector through the C1 end or C2 end of the first plug, and the second plug of the thermal protector is connected to the first terminal of the common end of the main and auxiliary windings of the compressor through the second plug pin, so that the thermal protector is connected in series in the compressor motor circuit. When the grid voltage is too high or the refrigeration system fails, the thermal protector is activated, thereby cutting off the power supply to protect the compressor motor. The N2 terminal of the starter N terminal plug, the starting coil, the starter M pin, the third terminal and the thermal protector form an energized circuit.

[0034] Compared with the prior art, the present invention has the following advantages: ① The moving and static contacts of the heavy hammer starter thermal protector in the present application are welded, the welding strength is firm, the contact resistance consistency is good, it is not easy to heat up and the contact life is enhanced. ② The contacts are automatically welded, and the production efficiency is high.

[0035] 1. The power supply neutral line, refrigerator temperature controller, and indicator light power supply connection only need to be electrically connected to the corresponding terminal of the starting thermal protector. The plastic cover 7 is neatly wired, which reduces the manufacturing space of the plastic cover 7, reduces the manufacturing cost of the plastic cover 7, and is conducive to the miniaturization design of the compressor.

[0036] 2. A starting capacitor Cs is connected in series between the second connecting plug and the N4 terminal of the starter N-terminal plug, and an operating capacitor Cr is connected in series between the starter pin and the N3 terminal of the starter N-terminal plug, thereby improving the starting performance and working efficiency of the compressor.

[0037] 3. The first pin is provided with C1 and C2 terminals, the L-end connecting plug is provided with L1, L2 and L3 terminals, the grounding connecting plug is provided with PE1, PE2, PE3 and PE4 terminals, and the starter N-end plug is provided with N1, N2, N3 and N4 terminals. The terminals are arranged in parallel to eliminate hidden dangers such as short circuit caused by connector touching the wires and improve safety.

[0038] 4. The assembly equipment can realize the automatic assembly of the movement components. The turntable can be used to switch between the moving piece placement station, spring placement station, armature placement station, axis placement station, riveting station and material removal station. The movement components are key components in the heavy hammer starter. The movement components are assembled and processed by automatic equipment, which not only improves the efficiency but also ensures the quality of the movement components, so that they can move smoothly in the movement installation cavity and have good contact points, making the starting more stable and greatly improving the product quality.
