Description

Technical Field

[0001] This utility model relates to the field of compressor assembly technology, and in particular to a compressor motor lead harness assembly tool. Background Technology

[0002] Assembling a refrigerator compressor requires installing the assembled pump body into the lower housing of the compressor, and then assembling the motor lead harness block onto the terminals of the housing. Due to the limited space in the compressor housing, the gap between the cylinder head on the pump body and the inner wall of the lower housing is normally around 6 mm. With the trend towards compressor miniaturization, this gap is getting smaller, now generally between 4-6 mm. When the gap between the pump body and the housing is large, the motor lead harness block can be assembled by gripping it with fingers or pliers. However, with the reduced gap, plier operation becomes very inconvenient, resulting in low assembly efficiency. On the other hand, if the lead wire is lengthened to assemble the motor lead harness block first and then install the pump body, the wire increases cost, occupies housing space, and is not conducive to compressor miniaturization. Furthermore, after assembly, the lead wire is generally coiled within the space formed by the four compressor seat springs. An excessively long lead wire increases the probability of contact with the seat springs, and during compressor operation, the lead wire is prone to friction with the seat springs, leading to a risk of electrical leakage. Therefore, it is essential to design a lightweight, safe, and reliable tooling to quickly and efficiently assemble the motor lead harness block onto the terminals of the lower housing. Utility Model Content

[0003] To overcome the shortcomings of existing compressor motor lead harness blocks, such as inconvenience in assembly, the technical problem to be solved by this utility model is to provide a simple and practical compressor motor lead harness block assembly tool.

[0004] The technical solution adopted by this utility model to solve its technical problem is: The compressor motor lead harness assembly tool includes a U-shaped shift fork head composed of a plug plate, a connecting plate, and a baffle connected in sequence, and a shift fork rod connected to the side of the connecting plate away from the U-shaped opening. The plug plate has a relief groove in the middle of the end away from the connecting plate, and the parts on both sides of the relief groove are plug-in parts. The side of the compressor motor lead harness block has a plug-in hole, and the end has a protrusion. The protrusion has guide holes on both sides. The width of the relief groove is adapted to the width of the protrusion, and when the protrusion is completely located in the relief groove, the plug-in parts on both sides match and plug into the guide holes.

[0005] Furthermore, the length of the plug-in plate is such that when the plug-in plate extends into the gap between the compressor pump body and the housing, and the connecting plate contacts the edge of the housing, the plug-in hole of the motor lead harness block installed at the end of the plug-in plate is aligned with the terminal block on the housing in height.

[0006] Furthermore, the distance between the plug plate and the baffle is such that when the inner side of the baffle contacts the outer wall of the housing, the motor lead bundle block installed at the end of the plug plate is located exactly at the inner end of the terminal block and abuts against it.

[0007] Furthermore, the length of the baffle is shorter than the length of the plug plate.

[0008] The beneficial effects of this utility model are as follows: By designing a U-shaped shift fork head with a shift fork lever, the motor lead wire bundle block is first installed onto the plug plate of the shift fork head. Then, the motor lead wire bundle block is inserted into the gap between the pump body and the housing using the plug plate. Finally, by swinging the shift fork lever, the reaction force between the baffle of the shift fork head and the housing causes the plug plate to generate a lateral thrust, thereby assembling the motor lead wire bundle block onto the terminal block on the side of the housing. The entire assembly tool has a simple structure, is easy to use, can meet the assembly needs of small compressors, and improves assembly efficiency. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] It should be noted that if this utility model contains directional indicators such as up, down, left, right, front, and back, these terms are used to describe the relative positional relationships between components and are not specific references to the absolute positions of the components or the relationships between them. They are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. If this utility model contains terms related to quantity such as "many," "multiple," or "several," these terms specifically refer to two or more.

[0013] like Figure 1 , Figure 2As shown, the compressor motor lead harness assembly tool provided by this utility model includes a U-shaped shift fork head formed by sequentially connecting a plug plate 1, a connecting plate 2, and a baffle 3, and a shift fork rod 4 connected to the side of the connecting plate 2 away from the U-shaped opening. The plug plate 1 has a clearance groove 11 in the middle of the end away from the connecting plate 2, and the parts on both sides of the clearance groove 11 are plug-in portions 12. Figure 3 , Figure 4 The motor lead harness block 5 of the compressor has a plug-in hole 51 on its side. The plug-in hole 51 is used to connect to the terminal block 8 on the side of the compressor housing 7. The terminal block 8 is connected to the power supply through an external connector, thereby supplying power to the compressor pump body 6. The existing motor lead harness block 5 has a protrusion 52 at its end, and guide holes 53 are provided on both sides of the protrusion 52. The width of the relief groove 11 of the plug plate 1 is adapted to the width of the protrusion 52 of the motor lead harness block 5, and the depth is longer than the length of the protrusion 52. When the protrusion 52 is completely located in the relief groove 11, the plug-in parts 12 on both sides are matched and plugged into the guide holes 53. The plugging of the two is an interference fit, ensuring that the motor lead harness block 5 can be stably installed on the plug plate 1.

[0014] The usage process of this utility model is as follows: Figure 5 As shown, first, the motor lead harness block 5, connected to the pump body 6 of the compressor, is installed onto the end of the plug-in plate 1 through the guide hole 53 and the mating of the plug-in part 12. Then, the pump body 6 is placed into the compressor housing 7, and the plug-in plate 1 extends into the housing 7 through the gap between the pump body 6 and the housing 7. The baffle 3 is located outside the housing 7. When the motor lead harness block 5 reaches the vicinity of the terminal 8 on the bottom side of the housing 7, the position is adjusted appropriately so that the plug-in hole 51 on the motor lead harness block 5 is aligned with the terminal 8. Then, the shift fork 4 is rotated towards the middle of the housing 7. The abutment action between the baffle 3 and the outer wall of the housing 7 generates an outward lateral thrust on the plug-in plate 1, causing the terminal 8 to insert into the plug-in hole 51, thereby realizing the plug-in assembly of the motor lead harness block 5 and the terminal 8. Afterward, the shift fork 4 is pulled upward to disengage the plug-in part 12 of the plug-in plate 1 from the wire hole 53 of the motor lead harness block 5, and the shift fork head can be removed. This process is convenient and quick.

[0015] During installation, to facilitate alignment of the motor lead harness block 5 with the terminal block 8, the pump body 6 should be placed as far away from the terminal block 8 as possible when inserting it. This allows the installer to observe the alignment of the connector hole 51 with the terminal block 8. After proper assembly, the pump body 6 can be moved to the correct position. A further option is to set the length of the connector plate 1 such that when the connector plate 1 extends into the gap between the pump body 6 and the housing 7 of the compressor, and the connecting plate 2 contacts the edge of the housing 7, the connector hole 51 of the motor lead harness block 5 installed at the end of the connector plate 1 is aligned with the terminal block 8 on the housing 7 in height. In other words, the extension length of the connector plate 1 is limited by the contact between the connecting plate 2 and the housing 7, thus determining the vertical position of the motor lead harness block 5. The lateral position can be determined by observing whether the shift fork head is located in the middle of the side of the housing 7, as the terminal block 8 is generally located in the middle of the side of the housing 7. This also facilitates the use of the connection between the connecting plate 2 and the baffle 3, which forms a fulcrum with the edge of the housing 7, to rotate the shift fork head.

[0016] In addition, to reduce the rotation angle of the shift fork head and ensure smooth insertion of the terminal 8 into the insertion hole 51, the distance between the insertion plate 1 and the baffle 3 should ideally be such that when the inner side of the baffle 3 contacts the outer wall of the housing 7, the motor lead bundle block 5 installed at the end of the insertion plate 1 is exactly abutting against the inner end of the terminal 8. This way, when the shift fork lever 4 is moved, the rotation angle of the motor lead bundle block 5 is small, avoiding problems with insertion and assembly caused by an excessively large angle between the terminal 8 and the insertion hole 51. Since the baffle 3 mainly provides reverse thrust, its length does not need to be too long; it can be shorter than the length of the insertion plate 1, as long as the baffle 3 has sufficient contact length with the housing 7 and does not interfere with other external structures of the housing 7.

[0017] This utility model first installs the motor lead wire bundle block 5 onto the plug plate 1 of the shift fork head, then uses the plug plate 1 to insert the motor lead wire bundle block 5 into the gap between the pump body 6 and the housing 7, and finally, by swinging the shift fork rod 4, the reaction force between the baffle 3 of the shift fork head and the housing 7 causes the plug plate 1 to generate a lateral thrust, thus assembling the motor lead wire bundle block 5 onto the terminal block 8 on the side of the housing 7. The entire assembly tool has a simple structure, is easy to use, can meet the assembly needs of small compressors, and improves assembly efficiency, thus having good practicality and application value.
