As shown in the attached Figure 4 figures, after this conventional metal frame is fixedly connected to the sheet-type connection terminal, although it provides a top surface that facilitates parallel contact with the wire metal sheet, more side portions are also exposed, which makes short-circuit contact prone to occur between the two metal frames of the relay, thus causing damage to the relay or even other electronic components. Meanwhile, the fixation between the conventional metal frame and the sheet-type connection terminal is not firm, shaking is likely to occur, and the problem of poor contact still exists.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to the appendix Figure 1 To be continued Figure 3This embodiment provides a relay for an electric water heater, including a relay body 1, an electrical connection assembly 2, and a reinforcing mechanism 3. The top of the relay body 1 is provided with a first terminal 11 and a second terminal 12 arranged along the height direction. The electrical connection assembly 2 includes a first copper post 21 and a second copper post 22. The reinforcing mechanism 3 includes an end cover 31 and a protective enclosure 32 provided on the end cover 31. The end cover 31 has a plurality of clearance openings 311, and each clearance opening 311 has an abutment edge 312 on its side. The end cover 31 covers the top of the relay body 1. The first terminal 11 and the second terminal 12 pass through the corresponding clearance openings 311. The first copper post 21 is fixedly connected to the first terminal 11, and the second copper post 22 is fixedly connected to the second terminal 12. The bottoms of the first copper post 21 and the second copper post 22 abut against the corresponding abutment edge 312. The protective enclosure 32 is arranged around the sides of the first copper post 21 and the second copper post 22. The relay for an electric water heater in this embodiment is provided with an electrical connection component 2 adapted to the relay body 1, and a reinforcement mechanism 3 is further provided to ensure a firm connection between the electrical connection component 2 and the relay body 1. The relay body 1 is provided with a first terminal 11 and a second terminal 12. The electrical connection component 2 includes a first copper pillar 21 and a second copper pillar 22. The side of the copper pillar is attached to the surface of the terminal, which indirectly increases the contact area between the terminal and the wire metal piece. That is, the wire metal piece can be horizontally attached to the top of the copper pillar to achieve connection with the terminal. At the same time, the reinforcement mechanism 3 includes an end cover 31 and a protective enclosure 32. The end cover 31 can be covered on the top of the relay body 1, and the protective enclosure 32 surrounds and protects the side of the copper pillar. At the same time, the bottom of the copper pillar presses against the abutment edge 312 to achieve locking. While protecting the side of the copper pillar, it can also prevent the copper pillar from shaking, so that the electrical connection between the relay and other electronic components in the electric water heater is more stable and reliable.

[0021] The protective enclosure 32 includes a first enclosure 321 and a second enclosure 322 arranged in a "U" shape. A first copper pillar 21 is sandwiched between the first enclosure 321 and the first terminal 11, and a second copper pillar 22 is sandwiched between the second enclosure 322 and the second terminal 12. Each enclosure and terminal surrounds the copper pillar in four directions on its side, restricting the swaying of the copper pillar. Both the first copper pillar 21 and the second copper pillar 22 are square. The first enclosure 321 and the first terminal 11 are simultaneously attached to the perimeter of the first copper pillar 21, and the second enclosure 322 and the second terminal 12 are simultaneously attached to the perimeter of the second copper pillar 22. In the attached state, the sides of the copper pillars can be protected to the greatest extent.

[0022] The abutment flange 312 is located at the bottom of the first enclosure 321 and the second enclosure 322 respectively. When each copper post is fixedly connected to the terminal, the copper post can simultaneously press against the abutment flange 312, lock the end cover 31, and prevent the end cover 31 from coming off the relay body 1.

[0023] The first terminal 11 and the second terminal 12 are arranged perpendicularly to each other. Based on this structural premise, the first copper post 21 and the second copper post 22 can be fixed in two mutually perpendicular directions respectively. Furthermore, both the first terminal 11 and the second terminal 12 are provided with terminal fixing holes 13, and both the first copper post 21 and the second copper post 22 are provided with copper post fixing holes 23 on their sides. The electrical connection assembly 2 also includes a plurality of screws 24, which pass through the terminal fixing holes 13 and are fixed to the copper post fixing holes 23.

[0024] In addition to being fixed with screws, the first copper post 21 can also be fixed to the first terminal 11 by welding, and the second copper post 22 can also be fixed to the second terminal 12 by welding.
