Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a contactor with high protection performance. Background Technology

[0002] Existing contactors have side attachment windows for accessories. When customers use the contactor without attachments, dust and powder can enter through these windows, settling on the contactor's magnet and silver contact surfaces. This can easily cause problems such as the contactor failing to engage, making abnormal noises after engagement, or lack of contact continuity. Furthermore, due to component assembly requirements, the contact system has poor protection. During use, dust and powder can enter through assembly gaps and settle on the silver contact surfaces, causing contact failure or unreliable weak signal conduction. This can also result in arcing from the holes, blackening the product surface and affecting its appearance while posing a safety hazard. Existing dustproof contactors only protect the side attachment windows, thus still suffering from poor contact system protection, leading to contact failure or unreliable weak signal conduction. Utility Model Content

[0003] This invention provides a contactor with high protection performance to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-protection contactor includes a contactor body, an upper housing at the top of the contactor body, and a lower housing at the bottom of the contactor body. The upper housing is symmetrically and detachably provided with sheet-like contact protective covers on the side near the contactor body. Finger protective covers are symmetrically and detachably provided on both sides of the sheet-like contact protective covers. A detachable magnetic system dust cover is also detachably provided on the side of the upper housing near the lower housing.

[0006] Furthermore, the upper housing has a plurality of first hook holes on the side near the contactor body, and the sheet-shaped contact protective cover has a plurality of first hooks on the side, and the first hooks are all matched and connected to the first hook holes.

[0007] Furthermore, the sheet-shaped contact protective cover is provided with multiple second hook holes, and the side of the finger guard is provided with multiple limiting hooks, and the limiting hooks are all matched and connected with the second hook holes.

[0008] Furthermore, the upper housing has a side attachment interface, and mounting ports are symmetrically provided on both sides of the side attachment interface. The side of the detachable magnetic system dust cover is provided with multiple second hooks, and the second hooks are matched and connected to the mounting ports. The lower housing also has a disassembly port that matches the side attachment interface.

[0009] Furthermore, the finger guard is also provided with multiple screw fastening holes evenly distributed on it.

[0010] This utility model has the following beneficial effects:

[0011] This utility model provides a high-protection contactor. A sheet-like contact guard is attached to the upper housing of the contactor, shielding the outside of the stationary contact. A finger guard is clipped onto the outside of the sheet-like contact guard on the upper housing, covering the screw fastening area of ​​the stationary contact. A screw fastening through-hole is also provided. A detachable magnetic system dust cover is clipped onto the side accessory mounting interface at the connection between the upper and lower housings. The detachable magnetic system dust cover can be removed from the contactor body using a screwdriver through the disassembly port. This multi-layered protection effectively prevents powder, dust, and salt stains from entering the contactor, greatly improving the overall dustproof, moisture-proof, and salt spray-proof performance of the contactor. It solves the problem that in current contactor applications, the lack of dust and impurity protection structures often leads to poor protection against dust and powder, ultimately causing contactor contacts to fail to conduct or unreliable weak signal conduction.

[0012] The sheet-shaped contact guard is attached to the contactor housing via two positioning hooks, covering the outside of the stationary contact assembly gap hole. This effectively prevents powder, dust, and stains from falling onto the contact surface and entering the contact system through the mating gap, thus improving the protection performance of the contactor contact system, enhancing the contact's low-current conduction capability and product connection reliability. The sheet-shaped contact guard can also effectively isolate the electric arc generated during the contactor's switching on and off, achieving zero arcing and improving product safety while avoiding the problem of blackening of the contactor's exterior parts during use, which affects the product's appearance.

[0013] The finger guard is attached to the finger guard mounting hole on the outside of the plate-shaped contact guard on the upper shell via limit hooks on the left and right sides. The screw fastening part of the stationary contact is also provided with screw fastening through hole, which effectively avoids the risk of electric shock caused by operators accidentally touching conductive parts, improves the electrical insulation performance of the contactor, and at the same time plays a limiting and guiding role for the wiring screw during wiring, avoiding problems such as screw tilting and slippage during operation.

[0014] When the contactor is not attached to the side for mounting accessories, the detachable magnetic system dust cover is attached to the mounting port of the detachable magnetic system dust cover at the connection between the upper and lower housings via left and right mounting hooks. This closes the accessory mounting window and effectively prevents dust and other impurities from entering the contactor, thus achieving the dustproof function of the contactor's magnetic system. This avoids the problem of the product failing to engage or making abnormal noises after engagement due to dust and other impurities falling onto the pole surface during product use.

[0015] The detachable magnetic system dust cover is also equipped with a disassembly port. When users need to attach side-mounted accessories, they can use a screwdriver to remove the detachable magnetic system dust cover from the contactor body through the disassembly port. There are no obstructions at the window for attaching side-mounted accessories to the contactor. Users can attach side-mounted accessories to the contactor through the window, which effectively improves the convenience of disassembly and assembly. Attached Figure Description

The lower housing 6 also has a disassembly port 17 that matches the side attachment interface 10.

[0028] The finger guard 3 is also provided with multiple screw fastening holes 15 evenly distributed on it.

[0029] In practical applications, the sheet-shaped contact protective cover 2 is attached to the first hooking hole 8 on the upper housing 5 of the contactor via two first hooks 12, covering the outside of the assembly gap hole 9 of the stationary contact 7. This effectively prevents powder, dust, and salt stains from falling onto the contact surface and entering the contact system through the assembly gap hole 9, thereby improving the protective performance of the contactor contact system, enhancing the contactor's ability to conduct weak current and improving the reliability of the product's connection. The sheet-shaped contact protective cover 2 can also effectively isolate the electric arc generated at the moment of contactor switching on and off, enabling the contactor to achieve zero arcing. This improves the safety performance of the product while avoiding the problem of the outer parts being blackened and affecting the product's appearance during the use of the contactor.

[0030] The finger guard 3 is attached to the second mounting hole 13 on the outside of the plate-shaped contact guard 2 of the upper housing 5 via the left and right limit hooks 14. The screw fastening part of the stationary contact 7 is also provided with a screw fastening through hole 15, which effectively avoids the risk of electric shock caused by the operator accidentally touching the conductive parts, improves the electrical insulation performance of the contactor, and at the same time plays a limiting and guiding role for the wiring screw during wiring, avoiding the problem of screw tilting and slippage during operation.

[0031] The detachable magnetic system dust cover 4 is attached to the mounting port 11 at the connection between the upper housing 5 and the lower housing 6 via the second hook 16 when the contactor is not attached to the side-mounted accessories. This seals the side-mounted accessory hanging interface 10, effectively preventing dust and other impurities from entering the contactor and realizing the dustproof function of the contactor's magnetic system. This avoids the problem of the product failing to engage or making abnormal noises after engagement due to dust and other impurities falling onto the pole surface during product use.

[0032] The detachable magnetic system dust cover 4 is also equipped with a disassembly port 17. When users need to attach side-mounted accessories, they can use a screwdriver 18 to remove the detachable magnetic system dust cover 4 from the contactor body 1 through the disassembly port 17. There are no obstructions at the side-mounted accessory mounting interface 10 of the contactor. Users can efficiently and conveniently attach side-mounted accessories to the contactor through the window, thus ensuring that while providing dust and debris protection, it also improves the convenience of disassembly and assembly. The overall optimization and improvement of the contactor's protective structure greatly enhances the dustproof performance of its contact system, magnetic system, and terminal parts. Therefore, this contactor has good practicality.
