[0035] A compressor typically includes a housing, terminals, a motor, and motor leads. The motor and motor leads are located inside the housing. One end of the terminals is exposed outside the housing, and the other end of the terminals extends into the housing and is connected to the motor via the motor leads.

[0036] Compressors can be divided into variable frequency compressors and fixed speed compressors. Variable frequency compressors typically do not require a protector; they only require a junction box. Specifically, in a variable frequency compressor, the motor leads can be pre-connected to the junction box. Then, the mounting holes on the junction box allow for the insertion and installation of the internal terminals, facilitating the connection and installation of the motor leads to the terminals. In other words, the junction box serves as an intermediate connector, allowing the terminals extending into the compressor to connect to the motor leads.

[0037] Because the junction box is installed inside the compressor and connected to the terminals that extend into the compressor, if conductive foreign objects such as copper shavings carried by the refrigerant adhere to the exposed parts of the terminals, it can easily cause short circuits, arcing, or burning between adjacent terminals or between the terminals and other metal components, leading to equipment malfunctions and safety hazards.

[0038] Therefore, how to reduce the risk of short circuits and other problems caused by the adhesion of conductive foreign matter to the terminals is a technical problem that urgently needs to be solved in this field.

[0039] In view of this, please refer to Figure 1 This utility model proposes a junction box 100 for use in compressors. The junction box 100 can reduce the risk of short circuits and other problems caused by the adhesion of conductive foreign matter to the terminal block 210.

[0040] Without loss of generality, the compressor has a terminal assembly 200 and a lead terminal assembly 300. The terminal assembly 200 includes at least two terminals 210, and the lead terminal assembly 300 includes at least two lead terminals (not shown in the figures). The outer end of the terminal 210 is exposed outside the compressor, and the inner end of the terminal 210 extends into the interior of the compressor and is connected to one end of the lead terminal through a junction box 100. The other end of the lead terminal is connected to a motor inside the compressor.

[0041] The lead terminal assembly 300 may include a motor lead 310, through which the lead terminal is connected to the motor. Alternatively, in other embodiments, the motor lead 310 may be omitted, and the motor may be directly connected to the lead terminal.

[0042] Please see Figure 1 In one embodiment of the present invention, the junction box 100 includes a first base 110 and at least two conductive terminals. The first base 110 has a mounting surface 111 facing the terminal 210. The mounting surface 111 is provided with at least two mounting holes 112 corresponding to the terminal 210. The at least two conductive terminals are respectively installed in the at least two mounting holes 112 and are electrically connected to the lead terminals. The portion of the inner end of the terminal 210 inserted into the mounting hole 112 is electrically connected to the conductive terminal. The inner end of the terminal 210 has a terminal exposure section 211 exposed outside the mounting hole 112.

[0043] The compressor has a compression chamber for refrigerant flow. The inner end of the terminal 210 refers to the portion that extends into the compression chamber. This inner end can be divided into two areas: the outermost area extends completely into the mounting hole 112, while the remaining area is exposed outside the mounting hole 112. This exposed area outside the mounting hole 112 is defined as the terminal exposure section 211. If conductive foreign matter such as copper shavings carried by the refrigerant adheres to the terminal exposure section 211, it can easily cause short circuits, arcing, or burning between adjacent terminals 210 or between terminals 210 and other metal components, leading to equipment failure and safety hazards.

[0044] Please see Figures 1 to 2 In one embodiment, the junction box 100 may optionally include a partition protrusion 120, which is disposed on the mounting surface 111 and has a clearance hole 121 communicating with the mounting hole 112. The clearance hole 121 is used for the terminal 210 to pass through and be inserted into the mounting hole 112. The partition protrusion 120 covers the outer periphery of the exposed terminal section 211.

[0045] Thus, by providing a partition protrusion 120 on the mounting surface 111, the partition protrusion 120 can wrap around the outer periphery of the terminal exposed section 211 to provide radial shielding for the terminal exposed section 211, thereby reducing the probability of conductive foreign objects approaching and adhering to the terminal exposed section 211, thereby reducing the risk of short circuits and other problems caused by conductive foreign objects adhering to the terminal 210.

[0046] The partition protrusion 120 has various structural forms; for example, please refer to [reference needed]. Figure 1 In one embodiment, the partition protrusion 120 is configured as a boss structure, and the clearance hole 121 includes at least two receiving grooves 122 spaced apart on the platform. A mounting hole 112 is correspondingly connected to the bottom surface of one receiving groove 122, and the exposed terminal section 211 is at least partially received within the receiving groove 122. That is, the receiving groove 122 and the mounting hole 112 are distributed axially, and the sidewall of the receiving groove 122 and the exposed terminal section 211 are distributed radially. In this embodiment of the present invention, axial refers to the direction of extension of the hole axis of the mounting hole 112, and radial refers to the direction perpendicular to the hole axis of the mounting hole 112.

[0047] In this way, each exposed terminal section 211 is surrounded and protected by the sidewall of a receiving groove 122, which further reduces the probability of conductive foreign objects forming a short circuit path between two adjacent exposed terminal sections 211, thereby further reducing the risk of short circuits and other problems caused by conductive foreign objects adhering to the terminal 210.

[0048] Of course, in other embodiments, the partition protrusion 120 may be configured as an annular rib structure, with the annular rib surrounding the outer periphery of all terminal exposure sections 211, that is, all terminal exposure sections 211 are disposed within the inner periphery space enclosed by the annular rib.

[0049] In one embodiment, optionally, the minimum thickness t of the sidewall of the receiving groove 122 is configured as follows: t ≥ 0.3 mm. For example, t can be 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2 mm. It is understood that if the minimum thickness t is too large, it will result in a larger external size and volume of the partition protrusion 120 and the junction box 100, which is not conducive to the arrangement and installation of the junction box 100 in the compression cavity.

[0050] In this way, on the one hand, it can ensure that the sidewall of the receiving groove 122 has a certain structural strength to avoid structural failure of the receiving groove 122; on the other hand, it is beneficial to the manufacturing and forming of the partition protrusion 120 and improve its production yield. Of course, in other embodiments, the minimum thickness t of the groove sidewall can also be other values.

[0051] Please see Figure 1 Optionally, the number of mounting holes 112 and receiving slots 122 can be three, and the number of conductive terminals and wiring terminals 210 can also be three. The three conductive terminals are respectively installed in the three mounting holes 112 and connected to the three wiring terminals 210 one by one. The distribution of the three receiving slots 122 on the platform of the partition protrusion 120 is roughly triangular, so that the structure of the junction box 100 can be more compact.

[0052] The cross-sectional shape of the mounting hole 112 and the receiving groove 122 can be circular, elliptical, or polygonal, etc., and the cross-sectional shape of the terminal 210 can also be circular, elliptical, or polygonal, etc. For example, please refer to... Figure 1 The cross-sectional shape of the terminal block 210, the mounting hole 112 and the receiving groove 122 can all be circular, and the diameter of the receiving groove 122 is larger than the diameter of the mounting hole 112.

[0053] In one embodiment, the partition protrusion 120 is optionally integrally formed with the first base 110. This simplifies the manufacturing process of the junction box 100, improves its production efficiency, and enhances the structural stability of the partition protrusion 120. More importantly, during the installation of the first base 110 to the terminal assembly 200, the partition protrusion 120 automatically wraps around the outer periphery of the exposed terminal section 211. That is, after the first base 110 is installed, the partition protrusion 120 can act as a shield, eliminating the need for additional installation operations on the partition protrusion 120 and thus saving on the compressor assembly process. Specifically, the partition protrusion 120 and the first base 110 are optionally integrally formed by injection molding. Of course, in other embodiments, the partition protrusion 120 and the first base 110 can also be separately formed and then assembled into one piece by fasteners such as screws, or directly welded together, or directly bonded together.

[0054] In order to meet the insulation and sealing requirements in the high-pressure, high-temperature and oil-refrigerant mixed environment inside the compressor, in one embodiment, the first base 110 and the partition protrusion 120 may optionally be made of polyester, polyphenylene sulfide or liquid crystal polymer.

[0055] In one embodiment, the conductive terminal may optionally be pre-embedded inside the base. For example, in an embodiment where the partition protrusion 120 and the first base 110 are integrally molded by injection molding, the conductive terminal and the first base 110 may be integrally injection molded. This simplifies the manufacturing process of the junction box 100, improves its production efficiency, and also enhances the structural stability of the conductive terminal. Of course, in other embodiments, the conductive terminal and the first base 110 may also be assembled together using adhesives or screws.

[0056] Please see Figure 2 In one embodiment, optionally, the side of the first base 110 is provided with a lead hole 113 corresponding to the lead terminal. The portion of the lead terminal inserted into the lead hole 113 is electrically connected to the conductive terminal, and the axis of the lead hole 113 intersects the axis of the mounting hole 112. Thus, the lead hole 113 is located on the side of the first base 110 and faces the side of the first base 110, reducing the probability of interference when the lead terminal and the wiring terminal 210 are installed on the junction box 100, thereby improving the ease of assembly.

[0057] In one embodiment, optionally, three lead holes 113 and lead terminals can be provided. The three lead terminals are respectively inserted into the three lead holes 113, and the three lead terminals are connected to the three conductive terminals one by one, so that the three lead terminals can be connected to the wiring terminal 210 through the conductive terminals.

[0058] Please see Figure 2 In one embodiment, optionally, the terminal assembly 200 further includes a second base 220, the second base 220 including a base plate portion 221 and a cover portion 222, the terminal 210 passing through the base plate portion 221, the cover portion 222 being disposed on the plate surface of the base plate portion 221 near the junction box 100, and the partition protrusion 120 being at least partially received in the inner peripheral space of the cover portion 222.

[0059] That is, the inner end of the terminal 210 passes through the substrate portion 221 and through the inner peripheral space of the cover portion 222, and then extends into the mounting hole 112 after passing through the receiving groove 122, so as to connect with the conductive terminal in the mounting hole 112; the platform of the partition protrusion 120 is located on the side of the cover opening of the cover portion 222 near the substrate portion 221, and the partition protrusion 120 and the cover portion 222 are arranged opposite each other in the radial direction. In this way, the partition protrusion 120 and the cover portion 222 are arranged opposite each other in the radial direction, which can further reduce the probability of conductive foreign objects carried by the refrigerant approaching and adhering to the terminal 210. Of course, in other embodiments, the cover portion 222 may not be provided.

[0060] This utility model also proposes a compressor, which includes a housing, a terminal assembly 200, a lead terminal assembly 300, and a junction box 100. The specific structure of the junction box 100 is as described in the above embodiments. Since this compressor adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0061] The housing has a compression chamber, the terminal assembly 200 includes at least two terminals 210, one end of the terminal 210 extends into the compression chamber, the lead terminal assembly 300 includes at least two lead terminals, the junction box 100 is disposed in the compression chamber, the part of the terminal 210 inserted into the mounting hole 112 is electrically connected to the conductive terminal, and the conductive terminal is electrically connected to the lead terminal.

[0062] Please see Figure 2 In one embodiment, the terminal assembly 200 may optionally include a second base 220, which includes a base plate portion 221 and a cover portion 222. The terminal 210 passes through the base plate portion 221, and the cover portion 222 is disposed on the plate surface of the base plate portion 221 near the junction box 100. The partition protrusion 120 is at least partially received in the inner peripheral space of the cover portion 222. Thus, the partition protrusion 120 and the cover portion 222 are arranged opposite each other in the radial direction, which can further reduce the probability of conductive foreign matter carried by the refrigerant approaching and adhering to the terminal 210. Of course, in other embodiments, the cover portion 222 may not be provided.

[0063] Optionally, the minimum distance D between the end face of the partition protrusion 120 and the plate surface of the base plate 221 is configured as: 0.1mm ≤ D ≤ 20mm. For example, the minimum distance D can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 5mm, 7mm, 10mm, 13mm, 15mm, 17mm, or 20mm. By leaving a certain distance between the end face of the partition protrusion 120 and the plate surface of the base plate 221, interference between the partition protrusion 120 and the base plate 221 can be avoided during the installation of the terminal assembly 200 into the junction box 100. On the other hand, if the minimum distance D is set too large, the size and volume of the junction box 100 and the terminal assembly 200 will be large, which is not conducive to the miniaturization design of the compressor.

[0064] Please see Figure 1 In one embodiment, optionally, the partition protrusion 120 is configured as a boss structure, and at least two receiving grooves 122 are provided at intervals on the boss surface. A mounting hole 112 is correspondingly connected to the bottom surface of one receiving groove 122, and the exposed terminal section 211 is at least partially received within the receiving groove 122. That is, the receiving groove 122 and the mounting hole 112 are distributed axially, and the sidewall of the receiving groove 122 and the exposed terminal section 211 are distributed radially. In this embodiment of the present invention, axial refers to the direction of extension of the hole axis of the mounting hole 112, and radial refers to the direction perpendicular to the hole axis of the mounting hole 112.

[0065] In one embodiment, optionally, the minimum distance d between the peripheral side surface of the partition protrusion 120 and the inner peripheral surface of the cover portion 222 is configured as: 0.1mm ≤ d ≤ 8mm. For example, the minimum distance d can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm. This reserved distance between the peripheral side surface of the partition protrusion 120 and the inner peripheral surface of the cover portion 222 prevents interference between the partition protrusion 120 and the cover portion 222 during the installation of the terminal assembly 200 into the junction box 100. On the other hand, if the minimum distance d is set too large, the size and volume of the junction box 100 and the terminal assembly 200 will be large, which is not conducive to the miniaturization design of the compressor.

[0066] In one embodiment, optionally, the circumferential lateral surface cross-sectional shape of at least a portion of the partition protrusion 120 is configured to match the inner circumferential surface cross-sectional shape of at least a portion of the cover portion 222, being circular, elliptical, or polygonal. For example, see [link to relevant documentation]. Figure 1 and Figure 2 In this embodiment, the peripheral surface of the partition protrusion 120 is approximately cylindrical, and the inner peripheral surface of the cover portion 222 includes a connected cylindrical section and a frustum-shaped conical section. The end of the frustum-shaped conical section away from the cylindrical section has a larger diameter and forms the opening of the cover portion 222. This facilitates the alignment and assembly between the junction box 100 and the terminal assembly 200, and also facilitates the processing and manufacturing of both.

[0067] Please see Figure 2 In one embodiment, the terminal assembly 200 may optionally include an insulating structure 230. The terminal 210 is sealed to the substrate portion 221 via the insulating structure 230. The insulating structure 230 at least partially protrudes from the surface of the substrate portion 221 near the junction box 100 and at least partially extends into the receiving groove 122. Thus, the insulating structure 230 serves both to mount the terminal 210 to the substrate portion 221 and to provide insulation between the terminal 210 and the substrate portion 221, preventing short circuits of the terminal 210 via the substrate portion 221, especially in embodiments where the substrate portion 221 is made of a conductive material. Optionally, the insulating structure 230 may be made of glass, ceramic, or other materials with good insulating properties. Of course, in other embodiments, the insulating structure 230 may not be provided.

[0068] Optionally, the minimum distance A between the peripheral surface of the insulating structure 230 and the inner peripheral surface of the receiving groove 122 is configured as follows: 0.05mm ≤ A ≤ 6mm. For example, the minimum distance A can be 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, 0.2mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, or 3mm. This reserved distance between the peripheral surface of the insulating structure 230 and the inner peripheral surface of the receiving groove 122 prevents interference between the insulating structure 230 and the sidewall of the receiving groove 122 during the installation of the terminal assembly 200 into the junction box 100. On the other hand, if the minimum distance A is set too large, the size and volume of the junction box 100 and the terminal assembly 200 will be large, which is not conducive to the miniaturization design of the compressor.

[0069] This utility model also proposes an air conditioner, which includes the aforementioned compressor. The specific structure of the compressor is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0070] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
