The connecting cylinder 23 is made of stainless steel. A positioning seat 232 is fixedly connected to the outer side of its open end by welding. The positioning seat 232 has an internal movable plug-in structure. The built-in movable component is a locking head 24. The locking head 24 can slide in the through groove of the positioning seat 232 to achieve a locking function. A locking plate 21 is fixedly connected to one end of the connecting cylinder 23 by bolt. The locking plate 21 is made of aluminum alloy material and is used to support the electrical control component. The locking plate 21 and the electrical control component are stably engaged and connected by a locking strip 22.

[0039] See Figure 3-5 The locking tongue 3 includes a positioning post 31 integrally formed with the connecting seat 12. The positioning post 31 is made of high-strength alloy material, and one end of it is fixedly connected to a fixing head 32 by bolts. The fixing head 32 is designed in the shape of a frustum and its surface is precision polished to ensure that frictional resistance is reduced when it is engaged with the locking head 24. The other end of the positioning post 31 is movably fitted with a movable head 33. The movable head 33 is designed in the shape of a flying saucer and its outer edge is designed with an arc transition to enhance contact stability. The main part of the locking tongue 3 extends into the connecting cylinder 23 and achieves the reset function through the elastic force of the second spring 4. The second spring 4 is sleeved on the outside of the locking tongue 3 and fixed on the inside of the connecting seat 12 to provide a reverse reset force.

[0040] See Figure 4 and Figure 6The side of the fixed plate 1 is symmetrically fixed with a first guide post 13. The first guide post 13 is made of corrosion-resistant alloy material and its outer surface is treated with anti-rust. The outer side of the opening end of the connecting cylinder 23 is fixedly connected with a guide seat 231 by bolts. The guide seat 231 is made of aluminum alloy material and its interior is designed as a cylindrical cavity, which fits tightly with the first guide post 13. The guide seat 231 is sleeved on the first guide post 13 and can slide along the guide post 13 to realize the smooth movement of the movable seat 2 on the fixed plate 1.

[0041] See Figure 6-7 One end of the positioning seat 232 has a through groove 2321. The inside of the through groove 2321 is designed as a rectangular structure to facilitate the sliding of the locking head 24 along the through groove 2321. The locking head 24 is made of hard plastic. One end of it is fixedly connected to a second guide post 241 by bolts. A first spring 25 is sleeved on the second guide post 241.

[0044] The working principle of this utility model is as follows:

[0045] When in use, first install the electrical control components in the distribution cabinet onto the card plate 21 by means of snap-fit, and then snap-fit ​​the card strips 22 set at both ends of the card plate 21 with the back of the electrical control components;

[0046] Then, hold the electronic control component by hand and put the connecting tube 23 onto the locking tongue 3. During the process of inserting the locking tongue 3 into the connecting tube 23, when the locking head 24 passes over the fixed head 32 and is in the space between the fixed head 32 and the movable head 33, stop applying pressure to the movable seat 2. Under the elastic force of the first spring 25, the locking head 24 will be locked on the back of the fixed head 32, so that the movable seat 2 can be connected with the locking tongue 3.

[0047] When it is necessary to remove the electronic control component, simply press the component to be removed with your hand. As the pressure increases, the locking head 24 will pass over the movable head 33. At this time, reduce the pressure on the electronic control component. Under the elastic force of the second spring 4, the locking head 24 will pass over the movable head 33 and the fixed head 32, thereby allowing the connecting cylinder 23 to separate from the locking tongue 3. The movable seat 2 can then be removed from the locking tongue 3, thus removing the electronic control component.

[0048] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
