Description

Technical Field

[0001] This utility model belongs to the field of compressor technology, specifically relating to a compressor grounding terminal structure with a quick-connect snap-fit. Background Technology

[0002] In modern industry and daily life, compressors are key equipment and are widely used in many fields such as refrigeration, air conditioning, and air compression. The grounding terminal is an important part of the compressor's electrical safety system, and its performance directly affects the stability of equipment operation and the personal safety of users.

[0003] During the actual operation of the compressor, due to various reasons such as internal winding short circuit, overload, and poor heat dissipation, the compressor or its internal components are prone to high temperature. For example, when the insulation layer of the compressor's internal windings ages due to long-term use, or when the copper plating phenomenon is caused by the corrosion of the winding insulation layer by acidic lubricating oil, which in turn causes a short circuit in the windings, a large amount of heat will be generated, causing the internal temperature of the compressor to rise sharply.

[0004] For example, in some refrigeration equipment, if the system is not properly sealed, it will cause refrigerant leakage. The compressor will need to consume more energy to maintain operation, which will also cause the compressor to overheat. When the temperature is too high, the existing grounding terminal structure cannot respond automatically. If the grounding terminal happens to have poor contact at this time, such as loose wiring due to long-term vibration, or oxidation at the connection between the terminal and the grounding wire, resulting in increased contact resistance, then in a high-temperature environment, the grounding terminal will heat up further due to resistance. This continuous abnormal temperature rise may not only damage the grounding terminal itself, but more seriously, it may also cause fires and other safety accidents, causing incalculable damage to the equipment and the surrounding environment.

[0005] Therefore, it is necessary to develop a device that can automatically disconnect when the compressor or its internal components reach high temperatures, thereby effectively avoiding safety hazards. Utility Model Content

[0006] The purpose of this invention is to provide a compressor grounding terminal structure with a quick-connect snap-fit, which can quickly achieve the snap-fit ​​effect and cause the terminal to disengage when the compressor or internal components are too hot, effectively preventing problems such as melting of wire insulation and short circuits caused by high temperature.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A compressor grounding terminal structure with a quick-connect snap-fit ​​includes a bottom contact terminal and a top plug-in terminal. A rotating ring is rotatably connected inside the bottom contact terminal. Two connecting pieces are fixed to the top of the rotating ring, and multiple first locking blocks are fixed to the inner side of each of the two connecting pieces.

[0009] The bottom end of the top plug terminal is inserted into the bottom contact terminal and placed inside the rotating ring. A second locking block is evenly arranged outside the top plug terminal and at the position corresponding to the first locking block, and the second locking block engages with the first locking block.

[0010] A driving structure is installed inside the bottom contact terminal, which is used to drive the rotating ring to rotate. Multiple pop-out structures are installed on the top of the bottom contact terminal, which are used to control the top plug-in terminal to pop out of the bottom contact terminal.

[0011] The driving structure includes a gear fixed to the outside of the rotating ring, a rack slidably connected inside the bottom contact terminal and meshing with the gear, a first spring connected between one end of the rack and the bottom contact terminal, an adsorption block provided at the other end of the rack, and an electromagnet installed inside the bottom contact terminal at a position corresponding to the adsorption block.

[0012] A conductive structure is installed inside the bottom contact terminal, and the conductive structure is used to control the electromagnet to be de-energized.

[0013] The conductive structure includes a conductive post fixed to the side of the electromagnet away from the adsorption block. A contact groove is provided at the bottom of the conductive post. A memory metal is fixed inside the bottom contact terminal and at the bottom of the contact groove, and the end of the memory metal is in contact with the contact groove.

[0014] The pop-out structure includes a second spring, which fixes the top of the bottom contact terminal. A lower pressure plate is fixed to the outside of the top insertion terminal, and the lower pressure plate is in contact with the second spring.

[0015] At least one limiting post is fixed to the top of the bottom contact terminal, and a sliding groove corresponding to the limiting post is provided on the lower pressure plate, and the limiting post is sleeved with the sliding groove on the lower pressure plate.

[0016] The first card block has balls evenly distributed on its top and bottom.

[0017] The technical effects achieved by this utility model are as follows:

[0018] This invention enables a quick plug-in latching effect through the interlocking of the first and second latching blocks. When the compressor or internal components are too hot, the electromagnet can be activated, thereby causing the bottom contact terminal and the top plug-in terminal to disengage from the terminal contact. This effectively prevents problems such as melting of the wire insulation layer and short circuits caused by high temperature, avoids serious safety accidents such as fire and explosion, and greatly improves the safety performance of the compressor.

Detailed Implementation

[0028] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0029] like Figures 1-7 As shown, a compressor grounding terminal structure with a quick-connect buckle includes a bottom contact terminal 1 and a top plug-in terminal 2. The inner side of the bottom contact terminal 1 and the bottom of the top plug-in terminal 2 are provided with a grounding terminal conductive sheet for reliably connecting the compressor metal shell or key components to the ground, thereby playing a role in safety protection and equipment operation stability. A rotating ring 3 is rotatably connected inside the bottom contact terminal 1. Two connecting pieces 4 are fixed on the top of the rotating ring 3, and multiple first locking blocks 5 are fixed on the inner side of each of the two connecting pieces 4.

[0030] The bottom end of the top plug terminal 2 is inserted into the bottom contact terminal 1 and placed inside the rotating ring 3. The second locking block 6 is evenly arranged on the outside of the top plug terminal 2 and at the position corresponding to the first locking block 5, and the second locking block 6 and the first locking block 5 are engaged with each other.

[0031] When the top connector 2 is inserted into the bottom contact terminal 1, the top connector 2 is at the center of the rotating ring 3 and gradually moves downwards via the second locking block 6, engaging with the first locking block 5, until the top connector 2 moves to the bottom inside the bottom contact terminal 1. The conductive piece on the top connector 2 then contacts the conductive piece inside the bottom contact terminal 1, stopping the movement of the top connector 2. The second locking block 6 can be made of a flexible material, such as rubber. As the second locking block 6 moves downwards, it can deform and move to the bottom of the first locking block 5. Figure 4 As shown, the upper side of the second locking block 6 is a flat surface and the lower side is an inclined surface, while the first locking block 5 is the opposite, with the upper side being an inclined surface and the lower side being a flat surface. Thus, when the second locking block 6 moves down, the first locking block 5 locks the second locking block 6.

[0032] A drive structure is installed inside the bottom contact terminal 1, which is used to drive the rotating ring 3 to rotate.

[0033] See attached document Figure 5 The drive structure includes a gear 7 fixed on the outside of the rotating ring 3, a rack 8 slidably connected in the bottom contact terminal 1 and meshing with the gear 7, a first spring 11 connected between one end of the rack 8 and the bottom contact terminal 1, when the first locking block 5 on the connecting piece 4 locks the second locking block 6, the rack 8 can be pulled by the first spring 11. Since the first spring 11 is in a stable state, the rack 8 is in a stable state. At this time, the gear 7 and the rotating ring 3 are also in a stable state, ensuring the locking effect of the first locking block 5 on the second locking block 6. An adsorption block 10 is provided at the other end of the rack 8. The adsorption block 10 can be made of magnetic material or iron material and can be attracted by the electromagnet 9. An electromagnet 9 is installed in the bottom contact terminal 1 and at the position corresponding to the adsorption block 10. In this state, the electromagnet 9 is in a de-energized state.

[0034] A conductive structure is installed inside the bottom contact terminal 1, which is used to control the electromagnet 9 to be de-energized.

[0035] See attached document Figure 5 and attached Figure 6The conductive structure includes a conductive post 12 fixed on the side of the electromagnet 9 away from the adsorption block 10. A contact groove 13 is provided at the bottom of the conductive post 12. A shape memory metal 14 is fixed in the bottom contact terminal 1 and at the bottom of the contact groove 13. The shape memory metal 14 is an existing mature technology. It is a special metal material that can recover its original macroscopic shape after plastic deformation in a certain temperature range and in another temperature range. The critical temperature at which its shape changes is called the "transformation temperature" or "phase transition temperature". When the shape memory metal 14 is in an environment below the phase transition temperature, its shape is called the "low temperature phase". When it is in an environment above the phase transition temperature, its shape is called the "high temperature phase". The end of the shape memory metal 14 is in contact with the contact groove 13.

[0036] When abnormally high temperatures occur in the compressor or its internal components within the bottom contact terminal 1, the temperature will also affect the shape memory metal 14. If the shape memory metal 14 is subjected to a temperature exceeding 80°C, it will deform, and its shape will shift from the attached... Figure 6 State transformation into attachment Figure 5 The device gradually moves to the position of the contact groove 13 and comes into contact with the conductive post 12. At this time, the shape memory metal 14 can conduct electricity with the conductive post 12 and conduct electricity to the electromagnet 9. After the electromagnet 9 is energized, it emits magnetism to attract the adsorption block 10, causing the adsorption block 10 to drive the rack 8 to move. Through the meshing connection between the rack 8 and the gear 7, the rack 8 can drive the gear 7 to rotate when it moves. At this time, the gear 7 drives the rotating ring 3 and the connecting piece 4 to rotate, and causes the first locking block 5 to rotate so that it does not lock with the second locking block 6. The top of the bottom contact terminal 1 is equipped with multiple pop-out structures. The pop-out structures are used to control the top plug-in terminal 2 to pop out of the bottom contact terminal 1, so that the top plug-in terminal 2 can pop out of the bottom contact terminal 1 through the pop-out structure, thus breaking the circuit. The user can check that the compressor or other components are correct before inserting the top plug-in terminal 2 into the bottom contact terminal 1.

[0037] If the temperature inside the bottom contact terminal 1 remains high, the first locking block 5 will not engage with the second locking block 6. If the temperature inside the bottom contact terminal 1 is low, the shape memory metal 14 will bend due to the "low temperature phase," causing it to no longer contact the conductive post 12. This will de-energize the electromagnet 9, and the first spring 11 will pull the rack 8 back to the reset state, causing the gear 7 and the rotating ring 3 to rotate, and causing the connecting piece 4 and the first locking block 5 to rotate to the reset state. After the second locking block 6 is inserted into the bottom contact terminal 1, it can re-engage with the first locking block 5. Furthermore, the top and bottom of the first locking block 5 are evenly provided with ball bearings 15. The ball bearings 15 facilitate the downward movement of the second locking block 6. When the first locking block 5 rotates due to high temperature, the ball bearings 15 will also reduce the friction between it and the second locking block 6, making rotation easier.

[0038] See attached document Figure 5 The pop-out structure includes a second spring 18, and the second spring 18 is fixed to the top of the bottom contact terminal 1. A lower pressure plate 16 is fixed to the outside of the top insertion terminal 2, and the lower pressure plate 16 is in contact with the second spring 18.

[0039] After the top plug terminal 2 is inserted into the bottom contact terminal 1, the lower pressure plate 16 can be moved towards the bottom contact terminal 1, compressing the second spring 18. If the first locking block 5 and the second locking block 6 are not in contact, the lower pressure plate 16 can be popped open by the second spring 18, causing the top plug terminal 2 to pop out into the bottom contact terminal 1. At least the conductive sheet on the top plug terminal 2 is no longer in contact with the conductive sheet on the bottom contact terminal 1. Furthermore, at least one limiting post 17 is fixed at the top of the bottom contact terminal 1. The plate 16 is provided with a sliding groove corresponding to the limiting post 17, and the limiting post 17 is sleeved with the sliding groove on the lower pressure plate 16. When the top plug-in terminal 2 is inserted into the bottom contact terminal 1, the sliding groove on the lower pressure plate 16 can be aligned with the limiting post 17, so that the top plug-in terminal 2 is always inserted into the bottom contact terminal 1 at the same angle, so that the first locking block 5 can be locked with the second locking block 6 without displacement. After the first locking block 5 is displaced, after the top plug-in terminal 2 is inserted into the bottom contact terminal 1, the first locking block 5 and the second locking block 6 are no longer locked.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
