Description

Technical Field

[0001] The utility model relates to the technical field of compressor manufacturing, in particular to a lead-out line adjustment structure and a compressor. Background Art

[0002] During the assembly process of the compressor, it is necessary to electrically connect the lead wires of the motor to the terminals on the upper housing. When the lead wires are too short, the upper housing and the motor cannot be connected, and the assembly of the compressor cannot be completed. When the lead wires are too long, the lead wires may touch the housing, causing the lead wires to burn. Alternatively, because the lead wires are too long, the lead wires may sag inward, causing interference between the lead wires and the motor rotor, so that when the compressor is running, the rotor will pull the lead wires off. Since the lead wires are energized, the above two situations where the lead wires are too long will cause electrical safety accidents. Therefore, if the lead wires are too long or too short, it will cause assembly failure or safety hazards. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0037] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] During the assembly process of the compressor, if the lead wire is too long or too short, it will cause assembly failure or safety hazards. In addition, during the trial production process, in order to meet customer needs, it is often necessary to change the angle of the upper cover and the height of the stator shrink sleeve. In this case, it is often necessary to replace the lead wire length or angle again. During the tense period of motor trial production, the trial production cycle is often difficult to guarantee. Or, when small batches are produced on site, if there is feedback that the lead wire is too long or too short, the countermeasures are often very limited. When the lead wire is too long, manual deflection of the lead wire is often used for installation. When the lead wire is too short, the corresponding process is more complicated, affecting production efficiency.

[0039] In order to overcome at least one defect in the prior art, the present embodiment proposes a lead wire adjustment structure, which can flexibly adjust the lead wire angle and / or lead wire length of the lead wire of the motor.

[0040] Please refer to Figure 1 and Figure 2 The present embodiment provides a lead wire adjustment structure 100, which is used in the compressor 200. It can adjust the lead wire angle and / or lead wire length of the motor lead wire 140, facilitate the electrical connection between the motor lead wire 140 and the terminal 212 on the housing 210, and is beneficial to improving the assembly efficiency of the compressor 200. It is suitable for a variety of assembly scenarios and has high flexibility.

[0041] The lead wire adjustment structure 100 includes a bracket 110 and an adjustment block 120. The adjustment block 120 is used to connect with the lead wire 140; the adjustment block 120 is connected to the bracket 110 and can move relative to the bracket 110. The adjustment block 120 moves relative to the bracket 110 to adjust the lead wire 140's lead wire angle and / or lead wire length. The lead wire adjustment structure 100 can flexibly adjust the lead wire 140's lead wire angle and / or lead wire length, facilitate the connection between the lead wire 140 and the terminal 212, improve assembly efficiency, and reduce the potential risk of the compressor 200. It can be understood that the lead wire adjustment structure 100 can be used alone to adjust the lead wire 140's lead wire angle, can also be used alone to adjust the lead wire 140's lead wire length, and can also be used to adjust the lead wire 140's lead wire angle and lead wire length at the same time.

[0042] Combination Figure 3 and Figure 4 There are many ways for the adjustment block 120 and the bracket 110 to move relative to each other. For example, a track 111 is provided on the bracket 110, and the adjustment block 120 can slide along the track 111. Optionally, the cross-section of the track 111 is I-shaped. The adjustment block 120 slides along the I-shaped track 111. The bracket 110 or the track 111 can be U-shaped, C-shaped, straight, L-shaped, circular, semicircular, fan-shaped, an arc of any angle, etc., which are not specifically limited here. The bracket 110 and the shell 210 of the compressor 200 are fixedly connected.

[0043] It can be understood that since the lead wire 140 is connected to the adjustment block 120 , when the adjustment block 120 is located at different positions of the bracket 110 , the lead wire 140 lead angle can be changed to meet the requirements of different installation angles.

[0044] Optionally, the bracket 110 is provided with a guide protrusion 112, and the guide protrusion 112 includes a first end 113 and a second end 114 opposite to each other, and the cross-section of the guide protrusion 112 gradually increases in the direction from the first end 113 to the second end 114. The adjustment block 120 is sleeved on the guide protrusion 112 and can slide along the guide protrusion 112. The sliding direction of the adjustment block 120 is the direction from the first end 113 to the second end 114. In this embodiment, a plurality of spaced guide protrusions 112 are provided on the bracket 110 along the laying direction of the track 111. The adjustment block 120 can only move unidirectionally in the direction from the first end 113 to the second end 114, such as Figure 4 The adjusting block 120 can be moved in the direction indicated by the arrow in the middle, but cannot be moved in the direction from the second end 114 to the first end 113. In this way, it is convenient to fix the adjusting block 120. When the adjusting block 120 moves to the appropriate position of the bracket 110, it will no longer move in the reverse direction, and the relative position of the adjusting block 120 and the bracket 110 can be kept unchanged. In this way, it is convenient to connect the lead wire 140 with the terminal 212 on the housing 210. Of course, in some embodiments, the number of the guide protrusion 112 can also be one, which is not specifically limited here.

[0045] In some embodiments, the guide protrusion 112 may be omitted. That is, the adjustment block 120 can slide bidirectionally on the track 111 of the bracket 110. When the position of the adjustment block 120 needs to be fixed, an additional fixing member may be provided to fix the adjustment block 120. When the position of the adjustment block 120 needs to be moved, the fixing member may be removed or dismantled to adjust the position of the adjustment block 120.

[0046] Optionally, a stopper 115 is provided on the bracket 110, and the stopper 115 is used to limit the moving range of the adjustment block 120 on the bracket 110. The stopper 115 can be fixed or movable. The number of the stopper 115 can be one or more, which is not specifically limited here. The sliding range of the adjustment block 120 on the bracket 110, such as the sliding angle, sliding distance, etc., can be flexibly set according to actual needs.

[0047] In some embodiments, the relative movement of the adjustment block 120 and the bracket 110 can also be achieved in this way. Optionally, the adjustment block 120 and the bracket 110 are detachably connected, and the adjustment block 120 can be fixed to at least one of the multiple different installation positions on the bracket 110. It can be understood that the adjustment block 120 and the bracket 110 are snap-connected to achieve the connection and separation of the two. When it is necessary to adjust the lead-out line 140, the adjustment block 120 can be removed first, the lead-out line 140 is adjusted to a suitable angle and length, and then the adjustment block 120 and the bracket 110 are snap-connected to press and fix the lead-out line 140. The number of the adjustment block 120 can be one or more.

[0048] Optionally, the adjusting block 120 is provided with a wire outlet hole 121, through which the lead wire 140 passes, so as to facilitate the overall constraint of the lead wire 140, so that the lead wire 140 remains regular and prevents contact with other parts such as the housing 210. The shape and size of the wire outlet hole 121 can be flexibly designed according to actual needs.

[0049] Optionally, the outlet hole 121 is provided with a clamping portion, which can selectively clamp or release the lead-out wire 140. In this embodiment, a notch 122 is provided on the hole wall of the outlet hole 121, and the hole wall provided with the notch 122 serves as a clamping portion, so as to change the aperture of the outlet hole 121 under the action of an external force. For example, the aperture of the outlet hole 121 is slightly smaller than the wire diameter of the lead-out wire 140, so that the lead-out wire 140 can be fixed and constrained to prevent the lead-out wire 140 and the adjustment block 120 from relative displacement. When it is necessary to adjust the length of the lead-out wire 140, that is, to allow the lead-out wire 140 and the adjustment block 120 to have a relative displacement, an external force is used to open the notch 122, so that the lead-out wire 140 is separated from the outlet hole 121. After the length of the lead-out wire 140 is adjusted, the lead-out wire 140 is clamped into the outlet hole 121 for fixing.

[0050] Alternatively, in some embodiments, the diameter of the outlet hole 121 is larger than the diameter of the lead wire 140, so that the lead wire 140 can be smoothly pulled out of the outlet hole 121 to change the length of the lead wire 140. When the lead wire 140 needs to be fixed, the lead wire 140 is fixed with an additional wire buckle or locking screw.

[0051] Optionally, the lead wire adjustment structure 100 further includes an elastic member 130. The elastic member 130 is connected to the bracket 110. The lead wire 140 is connected to the elastic member 130. The elastic member 130 may also be connected to the housing 210 of the compressor 200, which is not specifically limited here. The elastic member 130 may be made of a material or structure with a certain elastic coefficient, such as but not limited to a spiral spring, a rubber band, an elastic band, a spring or a spring. The lead wire 140 may be fixedly connected to the elastic member 130 by tying, tying, winding, welding, etc.

[0052] In this embodiment, the elastic member 130 is a coil spring. The elastic member 130 is fixed to the housing 210 , and the lead wire 140 is fixedly connected to the elastic member 130 , and then laid along the laying direction of the track 111 of the bracket 110 and passes through the lead hole 121 of the adjustment block 120 .

[0053] Optionally, an outlet end of the lead wire 140 is connected to a wiring terminal 141 , and the wiring terminal 141 is used to be electrically connected to the terminal post 212 .

[0054] The present invention also provides a compressor 200, including a motor, a housing 210 and the lead wire adjustment structure 100 as described above, wherein the bracket 110 is installed in the housing 210, and the motor is arranged in the housing 210. The motor has a lead wire 140, and the lead wire 140 is electrically connected to a terminal 212 on the housing 210.

[0055] Optionally, the housing 210 includes an upper cover 211 and a lower housing 213. The lower housing 213 has a receiving groove 214. The receiving groove 214 is used to install the motor. The upper cover 211 is arranged on one side of the notch of the receiving groove 214 of the lower housing 213. The upper cover 211 is provided with a terminal 212. The bracket 110 is fixed on the inner wall of the lower housing 213. The bracket 110 is provided with a circumferential track 111. The adjustment block 120 is movably arranged on the bracket 110 and can slide along the circumferential track 111. The elastic member 130 is fixed on the inner wall of the bracket 110 or the lower housing 213. After the lead wire 140 of the motor is fixedly connected to the elastic member 130, it is arranged along the direction of the track 111 of the bracket 110 and passes through the lead hole 121 of the adjustment block 120. After the connection terminal 141 of the outlet end is connected to the connection post 212, the upper cover 211 and the lower shell 213 are fixed to complete the assembly.

[0056] The use principle of the lead wire adjustment structure 100 is as follows:

[0057] Combination Figure 5 and Figure 6 If the lead wire 140 is too short during assembly, the lead wire 140 can be pulled out of the lead wire hole 121 with force. During the pulling process, the elastic member 130 is deformed and the spring becomes longer, which is equivalent to extending the lead wire 140. The lead wire angle remains unchanged, which is convenient for connecting the terminal 141 of the lead wire 140 and the terminal 212.

[0058] If the lead wire 140 is too long, the excess lead wire 140 can be wrapped around at least one of the elastic member 130, the bracket 110 and the adjustment block 120 to prevent the longer lead wire 140 from contacting the housing 210 or sagging too much.

[0059] Combination Figure 7and Figure 8 If the lead-out angle of the lead-out wire 140 deviates during assembly, the lead-out length is appropriate. At this time, the relative positions of the lead-out wire 140 and the adjustment block 120 remain unchanged, and the position of the adjustment block 120 on the bracket 110 is moved to adjust the lead-out angle. After adjusting to the appropriate lead-out angle, the terminal 212 is connected to the lead-out wire 140.

[0060] Similarly, if during the assembly process, the lead-out angle of the lead-out wire 140 deviates and the lead-out length is too short. You can first pull out the lead-out wire 140 with force to adjust the lead-out length. Then fix the lead-out position of the lead-out wire 140 in the lead-out hole 121. Then move the adjustment block 120 to adjust the lead-out angle to achieve a matching connection between the lead-out wire 140 and the terminal 212. Alternatively, first adjust the position of the adjustment block 120 on the bracket 110 so that the lead-out angle is suitable for assembly. Then pull out the lead-out wire 140 with force and adjust the lead-out length to match the connection with the terminal 212.

[0061] It should be noted that in the lead wire adjustment structure 100 in this embodiment, the shape, size, size, structure, etc. of the adjustment block 120 can be flexibly adjusted according to actual conditions. The shape, size, size, structure, etc. of the bracket 110 can be flexibly adjusted according to actual conditions. The fixing method of the bracket 110 and the housing 210 is not limited to bonding, welding, clamping, riveting, bolt connection or screw connection, etc., and is not specifically limited here.

[0062] In summary, the lead wire adjustment structure 100 and the compressor 200 provided by the embodiment of the utility model have the following beneficial effects, including:

[0063] The lead wire adjustment structure 100 provided by the embodiment of the utility model is provided with a relatively movable adjustment block 120 and a bracket 110, and the adjustment block 120 can flexibly adjust the lead wire angle and / or lead wire length of the lead wire 140, which is convenient for the connection between the lead wire 140 and the terminal 212, improves the assembly efficiency of the compressor 200, and avoids the problem that the lead wire 140 is too short or the angle offset is large and cannot be assembled. It can also reduce the risk of the lead wire 140 being too long and contacting the housing 210 or being broken by the motor rotor. In addition, during the trial production and mass production process, the lead wire adjustment structure 100 can quickly adapt to various assembly problems that occur on site, save resources for motor design, improve the response speed of processing the lead wire 140 size and lead wire angle changes, improve assembly efficiency, and shorten the production cycle. It is also convenient to unify the manufacturing sizes of various motors, which is conducive to the improvement of standardization, thereby helping to further reduce production costs.
