[0027] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0029] See also Figures 1 to 4 As shown, according to an embodiment of this application, a terminal block assembly includes:

[0030] The cylindrical body 1 is equipped with a conductive sheet 4 inside;

[0031] A cover plate 2 is provided on one end of the cylinder 1; the cover plate 2 is provided with through holes that pass through both sides;

[0032] The through hole is provided with a guide structure on the side away from the cylinder 1, which can guide the terminal 3 to be inserted into the through hole and electrically connected to the conductive sheet 4.

[0033] This application provides a guiding structure on the cover plate 2, which can guide the terminal 3, making it easier for the terminal 3 to pass through the through hole and connect with the conductive sheet 4. This eliminates the need for repeated hole alignment, reduces operational difficulty, and improves assembly efficiency.

[0034] A guide structure is provided on the outer side of the cover plate 2 of the terminal block to guide the abutting terminal 3 to the through hole, so that the terminal 3 can be inserted into the through hole and make contact with the conductive sheet 4 on the other side of the cover plate 2 to form an electrical connection. This eliminates the need for repeated hole alignment in the traditional method, effectively avoids wiring errors, reduces operational difficulty, reduces production steps, and effectively improves production and assembly efficiency.

[0035] In some embodiments, the guide structure includes a groove 21, the bottom surface of the groove 21 is inclined, and the extension direction of the groove 21 is the circumferential direction of the cover plate 2; the terminal 3 abuts against the groove 21 and can slide along the bottom surface of the groove to the through hole.

[0036] The guiding structure can specifically adopt a groove 21. The bottom surface of the groove 21 is inclined. When the terminal 3 contacts the bottom surface of the groove, the terminal 3 can slide inclinedly along the bottom surface of the groove to the through hole position, so that the terminal 3 can be inserted into the through hole. In this way, the electrical connection between the terminal 3 and the conductive sheet 4 can be completed with one hand, and the operation is easy.

[0037] In some embodiments, a bearing is provided between the cover plate 2 and the cylinder 1; the terminal block 3 abuts against and presses against the bottom surface of the groove, driving the cover plate 2 to rotate until the through hole is aligned with the terminal block 3.

[0038] A bearing is installed between the cover plate 2 and the cylinder 1, and the two are rotatable. When the terminal 3 contacts the bottom surface of the decompression groove, there is an oblique force that drives the cover plate 2 to rotate, so that the through hole moves relative to the terminal 3 until the terminal 3 passes through the through hole, which can realize the one-time insertion and alignment of the compressor terminal 3.

[0039] In some embodiments, two grooves 21 are provided on one side of the through hole, and the two grooves 21 are arranged symmetrically with respect to the through hole.

[0040] Grooves 21 are provided on both sides of the through hole and are arranged symmetrically with the through hole. This way, no matter which side of the through hole the groove 21 contacts the terminal 3, it can guide the cover plate 2 to rotate, making it easy for the terminal 3 to pass through the through hole.

[0041] In some embodiments, there are three through holes and three conductive sheets 4, which are evenly distributed around the circumference; the conductive sheet 4 is an arc-shaped sheet, and the three arc-shaped sheets form a ring, with adjacent conductive sheets 4 separated by a separator.

[0042] The through holes on the cover plate 2 are evenly distributed around the circumference, corresponding to the distribution of the three terminals 3. The corresponding conductive sheets 4 are also evenly distributed around the circumference inside the cylinder 1. The conductive sheets 4 are arc-shaped and form a ring with intervals between each other, which increases the circumferential distance between the terminals 3 and the conductive sheets 4, and realizes accurate, fast and efficient connection between the terminals 3 and the conductive sheets 4.

[0043] In some embodiments, the inner wall of the cylinder 1 is provided with three ribs, and the separator includes the ribs.

[0044] Ribs are placed between adjacent conductive sheets 4 to space and fabricate the conductive sheets 4, thereby stabilizing the structure of the conductive sheets 4 within the cylinder 1.

[0045] In some embodiments, the terminal assembly further includes an inner cylinder 5 disposed within the annulus; the inner cylinder 5 is movably connected to the cover plate 2.

[0046] An inner cylinder 5 is arranged within the annular space of the conductive sheet 4, so that the conductive sheet 4 abuts against the outer wall of the inner cylinder 5, and the cover plate 2 can be movably connected to the inner cylinder 5, making the entire product a one-piece structure. Preferably, the end face of the cover plate 2 near the cylinder 1 is provided with a buckle 24, and the inner wall of the inner cylinder 5 is provided with an annular groove 51, and the buckle 24 matches and engages with the annular groove 51.

[0047] The cover plate 2 and the inner cylinder 5 are connected by a snap fastener 24, which not only stabilizes the connection between the two but also facilitates the rotation between the cover plate 2 and the cylinder 1.

[0048] In the actual structure of the cylinder 1, conductive sheet 4 and inner cylinder 5, the cylinder 1 and conductive sheet 4 are spaced apart in the radial direction to facilitate the insertion of the terminal 3 and contact with the conductive sheet 4, while the conductive sheet 4 and inner cylinder 5 are in contact.

[0049] In some embodiments, the terminal assembly further includes a top cover 6, which is fixedly connected to the cylinder 1 and the inner cylinder 5.

[0050] To enhance the structural strength of the terminal block assembly, the top cover 6 is fixedly connected to the cylinder 1 and the inner cylinder 5 respectively.

[0051] like Figure 1 As shown, the terminal assembly of this application includes a top cover 6, a cylinder 1, a conductive sheet 4, an inner cylinder 5, a ball bearing 22, a cover plate 2, and a terminal post 3; wherein the cover plate 2 is provided with a through hole, and a corresponding groove 21 is provided on one side of the through hole, the three through holes are sequentially 120° apart, corresponding to the compressor terminal post 3.

[0052] The groove 21 on the cover plate 2 allows for the simultaneous insertion of three terminals 3. During installation, the three terminals 3 on the top of the compressor are inserted into the corresponding groove 21 on the cover plate 2. The bottom surface of the groove 21 consists of six inclined planes, each with the axis of symmetry around the three through holes. The inclined planes have the same inclination angle. When the terminal 3 contacts the bottom surface of the groove, axial pressure is applied by hand, and a pushing force is generated at the contact point, allowing the cover plate 2 to rotate around the center of the bottom cover. The compressor terminal 3 slides along the inclined plane to the through hole and is then inserted into the hole, making contact with the side wall of the conductive sheet 4 inside the cylinder 1 to achieve electrical connection. The compressor terminal 3 and the conductive sheet 4 are interference fit to ensure reliable insertion. At this time, there is a rib in the gap between two adjacent conductive sheets 4 to prevent the terminal 3 from being inserted into the gap.

[0053] The bearing structure between the cover plate 2 and the cylinder 1 can be constructed using balls 22 and bearing grooves 23 to achieve relative rotation between the cover plate 2 and the cylinder 1. The cover plate 2 and the inner cylinder 5 are connected by a snap fastener 24 that engages with an annular groove 51.

[0054] In actual setup, a notch 52 is provided at one end of the inner cylinder 5 to facilitate the connection of the screw 41 on the conductive sheet 4. The screw 41 is used to connect the power cord, which is routed through the outlet hole on the side of the top cover 6. This distribution method can ensure that the compressor wiring is connected smoothly and that the three-phase circuits are not interfered with.

[0055] According to another aspect of this application, a compressor is provided, including the terminal block assembly described above.

[0056] According to another aspect of this application, an air conditioning system is provided, including the terminal block assembly as described above or the compressor as described above.

[0057] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above description is merely a preferred embodiment of this application.
