Description

Technical Field

[0001] The utility model relates to a contactor, in particular to a split quick-install contactor. Background Art

[0002] A contactor is a widely used electrical switch that uses electromagnetic, pneumatic, or hydraulic principles to control the main circuit. While it offers advantages such as strong current-interrupting capability, rapid operation, safe operation, frequent operation, and remote control, it cannot interrupt short-circuit currents and, therefore, is typically used in conjunction with a fuse. While contactors primarily control electric motors, they can also be used to control other electrical loads such as welding machines and electric furnaces. Traditional contactors are tightly connected after assembly, making disassembly cumbersome and laborious. There is a lack of a product that offers quick disassembly and stable operation.

[0020] like Figure 1-Figure 5 As shown, a split quick-install contactor includes a shell body 1, wherein the shell body 1 is provided with a fixing seat 2 for assembling a coil, the fixing seat 2 is used to fix the coil, the coil is equipped with an iron core 3 and attracts the armature 4 to move after power is applied. This is a mature technical means and will not be elaborated on here. The shell body 1 also includes a sub-shell 5 on which the fixing seat 2 is installed, and a groove 6 for sliding insertion of the sub-shell 5 is provided on one side of the shell body 1. The groove 6 is provided with a locking position 7, a guide position 8 and a fixed position 9 from the entrance to the inside to limit the movement of the sub-shell 5. The design of the sub-shell 5 is to integrate the coil and iron core 3 parts that are vulnerable to damage and malfunction, which is conducive to quick disassembly and assembly operations without the need to disassemble the entire body, which is time-consuming and labor-intensive. Taking this embodiment as an example, during the insertion of the sub-shell 5, the sub-shell 5 is guided in the direction by the guide position 8, stops at the bottom at the fixed position 9 and is limited in relative up and down vibration. At the same time, the groove 6 is blocked at the locking position 7 at the entrance to limit disengagement.

[0021] The sub-housing 5 is provided with an elastic snap 10 at a position corresponding to the locking position 7. The locking position 7 has a locking groove 11 or a locking block 12 that engages with the elastic snap 10. The elastic snap 10 is a common locking method, and its specific implementation methods vary. In this embodiment, a three-pronged structure is used in conjunction with a dual spring. During use, the elastic snap 10 is locked in the locking groove 11 by the dual springs to prevent reverse separation from the housing body 1. It can also enter the opposite inner side of the locking block 12 to achieve blocking and limiting in the sliding direction. In this embodiment, a combination of the two methods is adopted to doubly ensure the structural stability and effectiveness after installation.

[0022] The guide latch 8 has a guide portion 13, which is provided with a guide groove 14 extending in the same direction as the channel 6. A guide strip 15 is provided on the outer wall of the sub-housing 5, which slidably engages with the guide groove 14. It should be noted that the guide portion 13 is shorter than the guide strip 15. This is because the guide portion 13 is placed in the channel 6 to avoid occupying too much space. The design of the guide portion 13 is primarily to guide the sub-housing 5 for smooth sliding installation, facilitating accurate engagement at the subsequent fixing latch 9.

[0023] The fixed position 9 has a fixing portion 16, and a fixing strip 17 is provided on the fixing portion 16. The side of the fixing seat 2 is provided with a protruding upper rib 18 and a lower rib 19. The fixing strip 17 slides between the upper rib 18 and the lower rib 19 to limit vibration. The design of the fixed position 9 is different from that of the guide position 8. The guide position 8 simply uses a guide strip 15 and may be damaged after long-term use, thereby affecting quality and safety. The fixed position 9 is specially designed with an upper rib 18 and a lower rib 19, which have a larger limiting plane and higher structural strength. The width of the upper rib 18 is greater than that of the lower rib 19. The upper rib 18 and the lower rib 19 are each provided with a reinforcing rib 20 connected to the fixing seat 2 to adapt to the collision characteristics caused by the reset and attraction of the armature 4, effectively improving the local structural strength.

[0024] The side wall of the sub-housing 5 has a positioning portion 21, with one end of the positioning portion 21 spaced from the side wall of the sub-housing 5. A retaining portion 22 and a retaining groove 23 are provided within the channel 6 for engaging with the end of the positioning portion 21. The sub-housing 5 can also be positioned in the insertion direction by engaging with the positioning portion 21, which facilitates fixed positioning near the entrance of the channel 6 and further improves overall stability.

[0025] The top surface of the fixing strip 17 is provided with a second reinforcing rib 24 that abuts against the upper rib 18. In this embodiment, the top surface of the fixing strip 17 is flush with the top surface of the fixing portion 16. The second reinforcing rib 24 enhances the strength of this area, preventing direct impact from the armature 4 when the coil is energized. A sliding groove 25 and a sliding rail 26 are provided between the channel 6 and the sub-housing 5. The groove 25 and the sliding rail 26 engage at a different location than the guide latch 8, providing multi-directional guidance that facilitates smooth and stable insertion.

[0026] The housing also includes a contact seat and armature 4 interlockingly assembled above the housing body 1. An iron core 3 is fixedly mounted between the fixed seat 2 and the sub-housing 5. The iron core 3 has a trident-shaped structure, with the fixed seat 2 mounted in the middle of the core 3. A return spring 27 is installed between the contact seat and the bottom of the slot 6. The structural design of the iron core 3 facilitates the passage of most of the magnetic flux through the core 3 after the coil is energized, generating a strong magnetic attraction. The return spring 27 also helps the armature 4 return to its original position after power is removed. This is based on basic principles, with adjustments made only to the specific core 3 and supporting structure.
