[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Example: See Figure 1-5 The present utility model provides a technical solution: a highly stable, waterproof, and corrosion-resistant transformer. This solution primarily addresses the problem of existing transformers, where, due to their inherent structural influences, the terminals and connections are susceptible to water contact or water intrusion, leading to leakage. This problem, which can easily cause electric shocks to workers working in rainy conditions or other situations where the transformer is contaminated with water, endangers their lives. The specific solution is as follows: the transformer comprises a mounting base 1, a fixed holder 2, and a movable holder 3. Urushiol resin varnish is applied to the exterior of the fixed holder 2 and the movable holder 3. Urushiol resin varnish is a solution formed by dehydrating, polycondensing, and diluting raw lacquer. This varnish overcomes the inherent toxicity of raw lacquer, dries quickly, and is relatively easy to construct.
[0025] Among them, the fixed card seat 2 and the movable card seat 3 are both fixedly installed on the mounting base 1, and a sealing gasket 8 is arranged between the fixed card seat 2 and the movable card seat 3. The sealing gasket 8 is made of flexible rubber material. After being squeezed by the fixed card seat 2 and the movable card seat 2, it can produce compression deformation. At this time, through the action of its own rebound force, the contact sealing of the fixed card seat 2 and the movable card seat 3 can be improved.
[0026] See also Figure 2 and Figure 4 The sealing gasket 8 includes a compression pad 81, and the compression pad 81 is symmetrically provided with an inclined surface 82 at the end corresponding to the fixed card seat 2 and the movable card seat 3. The inclined surface 82 can make the contact sealing between the fixed card seat 2 and the movable card seat 3 more convenient.
[0027] Furthermore, the compression pad 81 is provided between the fixed card seat 2 and the movable card seat 3, and the compression pad 81 is in movable contact with both the fixed card seat 2 and the movable card seat 3. The sealing pad 8 is in close contact with both the fixed card seat 2 and the movable card seat 3.
[0028] See also Figure 1 、 Figure 2 and Figure 5 Among them, the movable card seat 3 is connected to the fixed card seat 2 through the limit assembly 6. A wiring terminal 91 is provided under the fixed card seat 2, and a fixing sleeve 92 is provided on the outside of the wiring terminal 91. The outer end of the fixing sleeve 92 is connected to the sealing sleeve 9 through a thread. The sealing sleeve 9 is provided with an insertion for connecting the wire of the wiring terminal 91; after the sealing sleeve 9 is screwed into the fixing sleeve 92, the sealing sleeve 9 can protect the connection of the wiring terminal 91, thereby further improving the sealing of the connection of the wiring terminal 91.
[0029] Specifically, the limit assembly 6 includes a sliding seat 61. An adjustment bolt 7 is provided at the end of the sliding seat 61 corresponding to the movable clamping seat 3. The adjustment bolt 7 is threadedly connected to the movable clamping seat 3 and is located above and in the center of the adjacent terminal 91. A limit rod 62 is provided on the side of the sliding seat 61 away from the movable clamping seat 3. The adjacent limit rods 62 are arranged in a ring shape, and the limit rods 62 and the adjustment bolt 7 are parallel to each other. The end of the limiting rod 62 is provided with a clamping terminal 64, which is movably clamped on the fixed clamping base 2. The clamping terminal 64 and the limiting rod 62 form an angle less than 90 degrees, and the clamping terminal 64 and the fixed clamping base 2 are movably clamped; after rotating the adjusting bolt 7, the adjusting bolt 7 drives the sliding base 61 to move to the side away from the fixed clamping base 2. Through the connection between the clamping terminal 64 and the movable clamping base 3, at this time, the movable clamping base 3 and the fixed clamping base 2 fit each other, and the sealing gasket 8 can be squeezed, so that the fixed clamping base 3 and the fixed clamping base 2 fit more tightly, further ensuring the sealing of the mutual inductor and making the waterproof effect of the mutual inductor better.
[0030] See also Figure 1 In this example, the fixed base 2 and the mounting base 1 are connected by a locking bolt 4. A sliding screw 51 is threadedly connected to the lower end of the movable base 3. The mounting base 1 is provided with a guide groove 5 for the sliding screw 51. The sliding screw 51 and the locking bolt 4 are parallel to each other and arranged in a square shape on the mounting base 1. After the fixed base 2 and the movable base 2 are connected by the limiting assembly 6, the sliding screw 51 and the locking bolt 4 can securely mount both the fixed base 2 and the movable base 3 to the mounting base 1, further improving the operational stability of the transformer.
[0031] Working principle: When using this highly stable, waterproof and corrosion-resistant mutual inductor, the movable base 3 is clamped and fixed on the fixed base 2. At this time, the clamping end 64 is clamped on the fixed base 2; after rotating the adjusting bolt 7, the adjusting bolt 7 drives the sliding base 61 to move to the side away from the fixed base 2. Through the connection between the clamping end 64 and the movable base 3, the movable base 3 and the fixed base 2 fit together, and the sealing gasket 8 can be squeezed, so that the fixed base 3 and the fixed base 2 fit more tightly; and through the sliding screw 51 and the locking bolt 4, the fixed base 2 and the movable base 3 can be fixedly installed on the mounting base 1, further improving the stability of the mutual inductor.
