Description

Technical Field

[0001] The present invention relates to the technical field of compressor connectors, and more particularly to a highly reliable compressor connector. Background Art

[0002] A compressor is a mechanical device used to compress gases or liquids and is widely used in fields such as air conditioners, refrigerators, industrial manufacturing, and energy. In the prior art, the wiring of a compressor usually requires connecting a wire to the conductive post of the compressor through a connector. Through the connector, the wire can be quickly connected to the conductive post of the compressor without complex welding or screw fixation. When maintenance or wire replacement is needed, the connector can be quickly disassembled without disassembling other parts of the compressor. As a key component for realizing power transmission, the compressor connector needs to meet the requirements of convenience while ensuring reliability and safety.

[0003] For example, the compressor connector disclosed in the authorized publication number CN221009292U has a placement portion opened on its base. The placement portion includes a receiving hole and a receiving groove, and a top end is provided between the receiving hole and the receiving groove. The top end is provided with a limiting step on the side facing the receiving hole. The terminal at the front end of the wire group is bent to form a bent end, and the bent end is placed in the receiving hole and abuts against the outer circumference of the conductive post of the compressor. An anti-arch end is provided at the front end of the bent end and abuts against the limiting step through the anti-arch end.

[0004] However, in the actual use process, when the wiring terminal is installed and disassembled multiple times, each installation and disassembly will cause the anti-arch end to abut against the limiting step, generating friction and mechanical stress, resulting in wear. The wear will cause the shape of the anti-arch end to change, affecting its contact with the limiting step, and further may cause poor contact or loosening between the connection end and the conductive post of the compressor, reducing the reliability of the connector and affecting the normal operation of the equipment. Summary of the Invention

[0005] To ensure the reliability of the connector during long-term use, a highly reliable compressor connector is provided.

[0006] The above-mentioned inventive object of the present invention is achieved through the following technical solutions:

[0007] A highly reliable compressor connector includes a housing. A conductive connecting member is provided at the bottom of the housing, and a conductive post connected to the housing is fixed on the side of the conductive connecting member facing the housing. At least one placement portion is defined in the housing, and a wiring terminal is inserted into the placement portion. The placement portion includes a connecting cavity and a placement groove that communicate with each other. The wiring terminal includes a connecting end inserted into the connecting cavity and a wire bundling end installed in the placement groove. The connecting end is connected to the conductive post. It further includes a locking cover. The locking cover is connected to the housing and is located on the side of the wire bundling end facing away from the bottom of the placement groove. A limiting end is fixed on the side of the locking cover facing the placement groove. The limiting end is located in the placement groove and abuts against the side of the connecting end facing away from the direction in which the wiring terminal is inserted into the housing.

[0008] By adopting the above technical solution, through the design that the limiting end of the locking cover abuts against the connecting end, the position of the wiring terminal can be further restricted, ensuring stable contact between the wiring terminal and the compressor conductive post, and preventing the wiring terminal from loosening due to vibration. At the same time, the wiring terminal is inserted into the placement portion, and the design that the contact surfaces of the limiting end and the connecting end abut against each other will not cause frequent friction between the limiting end and the connecting end, thereby reducing the wear of the wiring terminal and ensuring the reliability of the connection between the connecting end and the conductive post.

[0009] Optionally, a limiting groove is formed on the outer side wall of the locking cover, a limiting block is fixed on the outer side wall of the housing, and the locking cover and the housing are clamped through the limiting groove and the limiting block.

[0010] By adopting the above technical solution, through the clamping design of the limiting groove and the limiting block, the position of the locking cover can be effectively fixed, preventing the locking cover from loosening or rotating due to vibration or other external forces, further improving the stability of the connection between the locking cover and the housing. At the same time, when it is necessary to maintain or replace the wiring terminal, the clamping structure makes the disassembly of the locking cover more convenient, without the need for complex tools or operations, reducing the maintenance cost and time.

[0011] Optionally, a barb extending towards the bottom of the placement groove is fixed at the bottom of the wiring terminal, a limiting member is fixed at the bottom of the placement groove, and the limiting member is clamped with the barb.

[0012] By adopting the above technical solution, through the clamping structure of the limiting member and the barb, the longitudinal displacement of the wiring terminal during vibration can be effectively restricted. Even in complex working conditions or during long-term operation, it can resist the pressure impact applied from different directions, so that the wiring terminal will not easily slide off its initial position and cause a short circuit.

[0013] Optionally, the side of the limiting member facing away from the insertion of the wiring terminal is set as an inclined surface.

[0014] By adopting the above technical solution, the inclined surface design of the fixed block can provide a better guiding effect for the limiting member of the terminal, making it easier for the limiting member to align with the clamping position of the fixed block during insertion, thereby improving the assembly success rate and efficiency.

[0015] Optionally, the connection end includes two relatively parallel connection pieces, the middle parts of the two connection pieces bulge towards the inner wall direction of the connection cavity, and the middle parts of the two connection pieces are in contact with the outer periphery of the conductive column.

[0016] By adopting the above technical solution, by bulging the middle part of the connection piece towards the wall of the placement groove, the bulging connection piece can better contact the conductive column, increasing the contact area between the connection piece and the compressor conductive column, reducing the increase in resistance or signal distortion caused by poor contact, thereby improving the current transmission efficiency and electrical conductivity, and ensuring a stable electrical connection.

[0017] Optionally, a plugging hole for plugging with the conductive column is opened at the bottom of the terminal, and the inner edge of the plugging hole bulges in the direction away from the insertion of the conductive column.

[0018] By adopting the above technical solution, the chamfer design on the outer periphery of the plugging hole can provide a better guiding effect for the insertion of the compressor conductive column, making it easier for the conductive column to align with the plugging hole. At the same time, after the conductive column is inserted, it can guide the conductive column to form a more stable contact with the plugging hole, thereby improving the connection stability.

[0019] Optionally, fixing members are fixed on both side walls outside the housing.

[0020] By adopting the above technical solution, fixing members are added. The fixing members are not on the same side as the housing. When it is necessary to connect or disconnect the connector from the compressor, the operator can support through the fixing members, reducing the sliding during the extraction of the connector, making the plugging of the connector housing and the conductive column more convenient. The user can quickly complete the plugging, improving the installation efficiency.

[0021] Optionally, an elastic reset member is arranged at the bottom of the connection cavity. The elastic reset member includes an elastic support plate. A support spring is fixed between the elastic support plate and the bottom of the connection cavity, and the elastic support plate is in contact with the end of the barb. A pressing component is fixed on the side of the limiting end facing the placement groove, and the pressing component is in contact with the terminal.

[0022] By adopting the above technical solution, when the lock cover is buckled, the pressing component first presses the terminal, and then the barb presses the elastic reset member to be engaged with the limiting member, so that the contact between the barb and the limiting member is buffered by the elastic reset member, reducing the impact and wear during direct contact.

[0023] Optionally, the side of the limiting end facing the placement slot is flush with the inner wall of the top side of the connecting cavity, the pressing assembly includes a fixing plate and a pressing rod, an adjusting cavity is opened in the lock cover, a knob assembly is installed in the adjusting cavity, the knob assembly includes a linkage rod, one end of the linkage rod passes through the outside of the lock cover, and the other end is inserted into the fixing plate, a return spring is installed on the outer periphery of the linkage rod, a limiting protrusion is fixed on the end of the linkage rod inserted into one end of the fixing plate, a limiting groove along the circumference of the linkage rod is opened in the fixing plate, and the limiting protrusion is clamped with the side of the limiting end facing the placement slot.

[0024] By adopting the above technical solution, after pressing and rotating the knob assembly, the limiting protrusion slides into the limiting groove, the limiting protrusion will be disengaged from the limiting end, the elastic potential energy of the reset spring will pull the fixed plate into the adjustment cavity, the pressure rod will no longer clamp the terminal, the terminal will be bounced up by the elastic reset part, and then the terminal can be plugged in and out, the terminal can be replaced or maintained without removing the lock cover, and the maintenance efficiency of the terminal is improved by pressing and rotating the knob assembly.

[0025] Optionally, when the limiting protrusion slides in the limiting groove, the side of the fixing plate facing away from the locking cover is flush with the side of the limiting end facing the placement groove.

[0026] By adopting the above technical solution, when the linkage rod is pressed and rotated, the limiting protrusion on the end of the linkage rod will slide into the limiting groove, and the elastic deformation of the compression spring in the adjustment cavity will be restored, thereby driving the fixed plate to enter the adjustment cavity, and the side of the fixed plate facing away from the lock cover is flush with the side of the limiting end facing the placement groove, avoiding the blocking of the connection end by the fixed plate, reducing the risk of blocking the fixed plate during the plugging and unplugging process of the terminal.

[0027] In summary, the present invention has at least the following beneficial effects:

[0028] 1. Through the abutment between the limit end and the connection end and multiple limit structures such as the barb and the limit piece, the stability and reliability of the terminal block in a high vibration environment are ensured, effectively preventing loosening and displacement.

[0029] 2. When maintenance is required, after pressing and rotating the knob assembly, the linkage rod drives the fixing plate to be retracted into the adjustment cavity, and the elastic reset part automatically bounces up the terminal, making it easier to pull out the terminal without removing the lock cover, reducing maintenance steps and improving maintenance efficiency.

Detailed implementation manners

[0038] The following is further introduced in detail with reference to the accompanying drawings of the specification:

[0039] First embodiment

[0040] As shown in the attached Figure 1 and attached Figure 2 A highly reliable compressor connector includes a housing 1. A conductive connecting member 2 is provided at the bottom of the housing 1, and a conductive column 21 inserted into the housing 1 is fixed on one side of the conductive connecting member 2 facing the housing 1.

[0041] At least one placement portion 3 is provided in the housing 1. Here, the number of placement portions 3 is three. Three terminal blocks 4 are respectively installed in the three placement portions 3. The three terminal blocks 4 are respectively inserted into the three placement portions 3. The placement portions 3 on both sides of the housing 1 are relatively parallel, and the middle placement portion 3 extends in the direction away from the direction in which the terminal block 4 is inserted into the placement portion 3, adaptively reducing the housing 1 and reducing the distance required for the terminal block 4 to be inserted into the housing 1, which helps the installation of the terminal block 4; the placement portion 3 is sequentially provided with a placement groove 31 and a connecting cavity 32 along the insertion direction of the terminal block 4. One side of the placement groove 31 is communicated with the connecting cavity 32, and the other side is communicated with the outside.

[0042] As shown in the attached Figure 2 and the attached Figure 3 As shown, the terminal 4 includes a connection end 41 and a wire bundling end 42. The connection end 41 is fixedly connected to the wire bundling end 42. The connection end 41 is located within the connection cavity 32. The connection end 41 includes two relatively parallel connection pieces 411. The middle parts of the two connection pieces 411 bulge towards the inner wall direction of the connection cavity 32, and the middle parts of the two connection pieces 411 are in contact with the outer periphery of the conductive post 21. The bulging connection pieces 411 can better contact the conductive post 21, increasing the contact area between the connection piece 411 and the compressor conductive post 21 and ensuring stable electrical connection.

[0043] The bottom of the connection end 41 is provided with a socket hole 412 for plugging into the conductive post 21, and the inner edge of the socket hole 412 bulges in the direction opposite to the insertion direction of the conductive post 21. The chamfer design on the outer periphery of the socket hole 412 can provide a better guiding effect for the insertion of the compressor conductive post 21, making it easier for the conductive post 21 to align with the socket hole 412. At the same time, after the conductive post 21 is inserted, it can guide the conductive post 21 to form a more stable contact with the socket hole 412, thereby improving the connection stability.

[0044] As shown in the attached Figure 3 and the attached Figure 4 As shown, a barb 413 extending towards the bottom of the placement groove 31 is also fixed to the bottom of the connection end 41. A limiting member 311 is fixed to the bottom of the placement groove 31, and the limiting member 311 is engaged with the barb 413 to limit the longitudinal displacement of the terminal 4 during vibration. Even under complex working conditions or during long-term operation, it can withstand the pressure impact applied from different directions.

[0045] One side of the limiting member 311 facing away from the direction in which the terminal 4 is inserted into the housing 1 is set as an inclined surface, which can provide a better guiding effect for the limiting member 311 of the terminal 4, making it easier for the limiting member 311 to align with the clamping position of the fixed block during insertion, thereby improving the assembly success rate and efficiency.

[0046] The wire bundling end 42 is located within the placement groove 31. One end of the wire bundling end 42 is fixedly connected to the connection end 41, and the other end is connected to a wire for bundling the wire.

[0047] A lock cover 5 is also provided on the housing 1 and is snap-fitted to the outer wall of the housing 1. The lock cover 5 is located on the side of the wire bundling end 42 facing away from the bottom of the placement groove 31. A limiting end 51 is fixed to the side of the lock cover 5 facing the placement groove 31. The limiting end 51 is located within the placement groove 31, and the limiting end 51 abuts against the side of the connection end 41 facing away from the direction in which the terminal 4 is inserted into the housing 1, which can further limit the position of the terminal 4 and prevent the terminal 4 from loosening due to vibration.

[0048] As shown in the attachedFigure 1 As shown, a limiting groove 52 is formed on the outer side wall of the lock cover 5, and a limiting block 11 is fixed on the outer side wall of the housing 1. The lock cover 5 and the housing 1 are clamped through the limiting groove 52 and the limiting block 11, which can effectively fix the position of the lock cover 5. When it is necessary to maintain or replace the wiring terminal 4, the clamping structure makes the disassembly of the lock cover 5 more convenient, without the need for complex tools or operations.

[0049] Fixing members 12 are fixed on both side walls outside the housing 1. The fixing members 12 and the housing 1 are not on the same side. When it is necessary to connect or disconnect the connector from the compressor, the operator can support through the fixing members 12, reducing the sliding when pulling out the connector, making the insertion of the connector housing 1 and the conductive post 21 more convenient. The user can quickly complete the insertion, improving the installation efficiency.

[0050] Embodiment 2

[0051] This Embodiment 2 is an improvement based on Embodiment 1, and the rest of the structures are the same as those in Embodiment 1, so no more description will be given here.

[0052] As shown in the attached Figure 5 and attached Figure 6 As shown, an elastic reset member 13 is arranged at the bottom of the connection cavity 32. The elastic reset member 13 includes an elastic support plate 131 and a support spring 132. The elastic support plate 131 is parallel to the bottom of the connection cavity 32. One side of the elastic support plate 131 facing away from the bottom of the connection cavity 32 abuts against the barb 413; the number of the support springs 132 is multiple, and both ends of the multiple support springs 132 are respectively connected to the elastic support plate 131 and the bottom of the connection cavity 32. The contact between the barb 413 and the limiting member 311 is buffered by the elastic reset member 13, reducing the impact and wear during direct contact.

[0053] One side of the limiting end 51 facing the placement groove 31 is flush with the inner wall of the top side of the connection cavity 32. A pressing assembly 6 is fixed on one side of the limiting end 51 facing the placement groove 31. The pressing assembly 6 includes a fixing plate 61 and a pressing rod 62. One end of the pressing rod 62 is fixedly connected to the fixing plate 61, and the other end abuts against the wiring terminal 4.

[0054] As shown in the attached Figure 5 and attached Figure 7As shown, an adjustment cavity 53 for the fitting and sliding of the fixing plate 61 is formed in the lock cover 5. A knob assembly 7 is installed in the adjustment cavity 53. The knob assembly 7 includes a linkage rod 73. One end of the linkage rod 73 penetrates to the outside of the lock cover 5, and a knob 71 is fixed to the end. Threads are provided on the outer periphery of the knob 71 for easy rotation. The other end of the linkage rod 73 is located inside the fixing plate 61, and two limit protrusions 731 are fixed on the outer periphery of the end. A limit groove 611 in the circumferential direction of the linkage rod 73 is also formed in the fixing plate 61, and both limit protrusions 731 slide movably in the limit groove 611.

[0055] The knob assembly 7 further includes a fixing ring 74 and a return spring 72. The fixing ring 74 is located on the outer periphery of the linkage rod 73. At the same time, the fixing ring 74 is located on one side of the fixing plate 61 in the adjustment cavity 53 and is fixedly connected to the fixing plate 61. The return spring 72 is located on the outer periphery of the linkage rod 73. One end of the return spring 72 is fixedly connected to the side of the fixing ring 74 facing away from the fixing plate 61, and the other end of the return spring 72 is fixedly connected to the groove wall on the top side of the adjustment cavity 53.

[0056] After pressing and rotating the knob assembly 7, the limit protrusion 731 slides into the limit groove 611, and the limit protrusion 731 will disengage from the clamping with the limit end 51. The elastic potential energy of the return spring 72 will pull the fixing plate 61 into the adjustment cavity 53, and the pressing rod 62 will no longer clamp the terminal 4. The terminal 4 is bounced up by the elastic resetting member 13, and then the terminal 4 can be inserted and removed. It is not necessary to remove the lock cover 5 to replace or maintain the terminal 4. By pressing and rotating the knob assembly 7, the maintenance efficiency of the terminal 4 is improved.

[0057] Working effect

[0058] Through the above specific implementation manners, it can be seen that the high-reliability compressor connector of the present invention has multiple limiting and fixing functions in the structural design. Combining the optimized design of the elastic resetting member 13 and the pressing assembly 6, the stability and reliability of the connector under high vibration and complex working conditions are significantly improved.

[0059] At the same time, the innovative design of the knob assembly 7 makes the maintenance operation more convenient. It is not necessary to remove the lock cover 5 to complete the extraction and replacement of the terminal 4, which greatly reduces the maintenance cost and time. It not only meets the requirements of high reliability and high stability in the industrial environment, but also improves the service life and maintenance efficiency of the connector through the optimized structural design.

[0060] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as they are within the scope required to be protected by the present invention, they are protected by the patent law.
