Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary structures for preventing errors in power wiring, and in particular to a structure for preventing misinsertion of power wiring in an excimer laser. Background Technology

[0002] The anti-misplugging structure for excimer laser power wiring is a core design to ensure the safe operation of the equipment and prevent circuit damage or personal injury caused by misoperation. Its core lies in achieving uniqueness, reliability and intelligence in the plugging process through multi-dimensional innovation in mechanics, electrical, human-machine interaction and material technology.

[0003] The existing power connectors do not have a mis-insertion prevention structure, which poses a risk of mis-insertion during the use of excimer lasers. Therefore, it is particularly important to design a mis-insertion prevention structure for excimer laser power connectors to solve the above-mentioned technical problem. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the risk of mis-insertion during the excimer laser process due to the lack of a mis-insertion prevention structure on the existing power supply terminal block, and to propose a mis-insertion prevention structure for the power supply terminal block of an excimer laser.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a power supply wiring anti-misinsertion structure for an excimer laser, comprising a machine body, a plug connected to the right side of the machine body via an auxiliary line, a terminal block provided on the right side of the plug, inserts mounted on the plug, the inserts being triangularly distributed, insert rods mounted on both sides of the top inserts, guide blocks fixedly connected to both sides of the insert rods, an auxiliary groove provided on the terminal block, and a contact groove provided on the terminal block, the position of the contact groove matching the position of the inserts, the inner wall shape of the auxiliary groove matching the shape of the insert rods, and the length of the insert rods being the same as that of the inserts.

[0006] Preferably, the inner wall of the auxiliary groove is provided with a slot, the shape of which matches the shape of the guide block.

[0007] Preferably, the guide blocks are symmetrically distributed on the insertion rod.

[0008] Preferably, a base is mounted on the top of the terminal block, and a rotatable protective plate is mounted on the base via a rotating rod.

[0009] Preferably, a torsion spring is installed on the outer side of the rotating rod, one end of the torsion spring is installed on the protective plate, and the other end of the torsion spring is installed on the base, with the torsion springs symmetrically distributed on both sides of the base.

[0010] Preferably, the protective plate is equipped with a handle.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, during use, symmetrical insertion rod structures are installed on both sides of the top insert, and guide block structures are set on both sides of the insertion rods to guide the insert into the connector slot, avoiding misinsertion. Compared with conventional plugs that do not have anti-misinsertion structures, this utility model has insertion rods and guide blocks on both sides of the top insert, which can effectively prevent plug misinsertion. The overall structure is directly installed on both sides of the top insert, optimizing the existing space structure, making it easy to install and maintain. It solves the problem of misinsertion risk in the excimer laser process due to the lack of anti-misinsertion structures on existing power connectors.

[0012] 2. In this utility model, the protective plate and torsion spring work together to effectively protect the terminal block during use. When the plug is not inserted, the protective plate remains closed under the action of the torsion spring, effectively preventing dust, moisture, and other impurities from entering the terminal block, ensuring the cleanliness and safety of the power wiring. When the plug needs to be inserted, the operator only needs to manually operate the handle to lift the protective plate, allowing for easy plug insertion. After insertion, the protective plate automatically resets under the action of the torsion spring, protecting the terminal block again. The entire operation is simple and quick, greatly improving work efficiency and safety. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] This utility model provides a structure to prevent mis-insertion of power wiring for an excimer laser, including a machine body. A plug 102 is connected to the right side of the machine body via an auxiliary line 101. A terminal block 2 is provided on the right side of the plug 102. Inserts 3 are mounted on the plug 102 in a triangular arrangement. Insert rods 301 are mounted on both sides of the top insert 3. Guide blocks 302 are fixedly connected to both sides of the insert rods 301. An auxiliary groove 303 and a contact groove 305 are provided on the terminal block 2, the position of which matches the position of the insert 3. The inner wall of the auxiliary groove 303 matches the shape of the plug rod 301. The plug rod 301 has the same length as the insert 3. A slot 304 is provided in the inner wall of the auxiliary groove 303. The shape of the slot 304 matches the shape of the guide block 302. The guide blocks 302 are symmetrically distributed on the plug rod 301. In use, the plug rod 301 and the guide block 302, in conjunction with the auxiliary groove 303 and the slot 304, achieve precise positioning and stable connection of the plug 102, solving the problem of mis-insertion risk caused by the lack of an anti-mis-insertion structure on the existing power socket 2. When the plug 102 is inserted into the socket 2, the plug rod 301 first enters the auxiliary groove 303, and the guide block 302 slides along the inner wall of the auxiliary groove 303 until it matches the slot 304. This process ensures the correct insertion direction of the plug 102 and avoids the possibility of mis-insertion. Meanwhile, the lengths of the insertion rod 301 and the insertion piece 3 are consistent, ensuring a stable and reliable electrical connection between the plug 102 and the terminal block 2. In actual use, before inserting the plug 102 into the terminal block 2, the operator manually operates handle 5 to lift the protective plate 402, causing the protective plate to rotate around the rotating rod 401 in the base 4. Before the plug 102 is inserted into the terminal block 2, the guide block 302 first inserts into the slot 304, then guides the insertion rod 301 into the auxiliary slot 303, and assists in guiding the insertion piece 3 into the contact slot 305. When the insertion rod 301 is fully inserted into the auxiliary slot 303, the insertion piece 3 is also fully inserted into the contact slot 305, completing the connection between the plug 102 and the terminal block 2. 2. Under the action of the torsion spring 403, it abuts against the plug 102, protecting the plug 102 at the terminal block 2 position. By symmetrically installing the plug rod 301 structure on both sides of the top plug 3 and setting the guide block 302 structure on both sides of the plug rod 301, the plug 3 is guided into the terminal slot 305, avoiding misinsertion. Compared with the conventional plug 102 without anti-misinsertion structure, the structure of plug rod 301 and guide block 302 on both sides of the top plug 3 can effectively avoid misinsertion of the plug 102. The overall structure is directly installed on both sides of the top plug 3, optimizing the existing space structure and making it easy to install and maintain.

[0018] Example 1 like Figure 1-5 As shown, a base 4 is mounted on the top of the terminal block 2. A rotatable protective plate 402 is mounted on the base 4 via a rotating rod 401. A torsion spring 403 is mounted on the outer side of the rotating rod 401. One end of the torsion spring 403 is mounted on the protective plate 402, and the other end is mounted on the base 4. The torsion springs 403 are symmetrically distributed on both sides of the base 4. A handle 5 is mounted on the protective plate 402. The overall effect of Embodiment 1 is that, during use, the protective plate 402 and the torsion spring 403 effectively protect the terminal block 2. When the plug 102 is not inserted, the protective plate 402 remains closed under the action of the torsion spring 403, effectively preventing dust, moisture, and other impurities from entering the terminal block 2, ensuring the cleanliness and safety of the power wiring. When it is necessary to insert the plug 102, the operator only needs to manually operate the handle 5 to lift the protective plate 402 to smoothly insert the plug 102. After insertion, the protective plate 402 automatically resets under the action of the torsion spring 403, protecting the terminal block 2 again. The entire operation process is simple and quick, greatly improving work efficiency and safety.

[0019] Working principle: Before inserting the plug into the terminal block, the operator manually lifts the protective plate by operating the handle, causing the protective plate to rotate around the rotating rod in the base. Before the plug is inserted into the terminal block, the guide block first inserts into the slot, then guides the plug rod into the auxiliary slot, and guides the prongs into the contact slot. When the plug rod is fully inserted into the auxiliary slot, the prongs are also fully inserted into the contact slot, completing the connection between the plug and the terminal block. The protective plate abuts against the plug under the action of the torsion spring, protecting the plug at the terminal block position.
