Description

Technical Field

[0001] The utility model relates to the technical field of PT cabinets, and more specifically to a secondary module connecting device for a PT cabinet. Background Art

[0002] With the continuous development of power systems and the increasing scale of power grids, the requirements for the stability, reliability and economy of power systems are becoming higher and higher. In this context, the technical development and application optimization of PT cabinet secondary modules, as an important component of the power system, have become the key to improving the performance of the power grid.

[0003] The connecting ball socket of the existing PT cabinet secondary module is symmetrically provided with fixing components, so that when the plug is fully inserted into the connector socket, the fixing component needs to be manually turned to fix the plug and the connector socket. In this way, the installer may neglect to manually turn the fixing component to fix the plug and the connector socket, resulting in the fixation of the plug and the connector being easily loosened and falling off the connector socket, making it impossible for the plug and the connector to be stably connected. During the operation and maintenance process, the connection status of the plug and the connector is not easy to observe and needs to be manually checked, which is very troublesome. In addition, the existing fixing component makes it very laborious to pull out the plug with only one hand. Utility Model Content

Detailed Description of the Embodiment

[0018] The following further describes the present utility model in detail with reference to the drawings.

[0019] This embodiment discloses a secondary module for a PT cabinet, as Figures 1 to 5As shown in the figure, it includes a rectangular housing. A connector socket 1 is provided on the upper end face of the rectangular housing. A plug 2 that matches the connector socket 1 is provided on the connector socket 1. There is a driven fixing component 11 movably connected to the connector socket 1, and the connection method is a hinge connection. The driven fixing component 11 includes a fixing hook 111 and a fixing buckle 112. The fixing hook 111 and the fixing buckle 112 are respectively located on both sides of the connector socket 1. There are driven pressing pieces 21 on both the fixing buckle 112 and the fixing hook 111. When the plug 2 is inserted into the socket, the driven pressing pieces 21 rotate around the hinge connection between the connector socket 1 and the driven fixing component 11 under the action of the thrust of the socket. There is a buckle A 3 on the fixing hook 111, and a slot 31 adapted to the fixing hook 111 is provided on the plug 2. The buckle cooperates with the slot 31 to fix the connection between the plug 2 and the connector. Due to the existence of the slot 31, it can also be used to assist in identifying the direction of the plug 2. There is a buckle B 4 on the described fixing buckle 112, and a buckle groove 41 adapted to the buckle B 4 is provided on the connecting hook. The fixing buckle 112 is connected to the fixing hook 111 through the buckle B 4 to further strengthen the connection relationship between the connector socket 1 and the plug 2. There is a spring 5 on the fixing buckle 112 and the fixing hook 111, and the spring 5 is connected to the connector socket 1. The elastic force of the spring 5 keeps the driven fixing component 11 in an open state under non-working conditions, so that when the plug 2 is inserted into the connector socket 1, there is no need to manually open the fixing component, reducing unnecessary processes and also avoiding the possibility of the small lamp 6 wrongly reflecting the connection state.

[0020] For further improvement, the plug 2 adopts a rectangular connector. There are no exposed terminals, ensuring safety and reliability when using this new type.

[0021] For further improvement, there is a light-emitting lamp on the connector socket 1. There are small lamp normally open switches 61 connected in series with the power supply in the box on both sides of the connector socket 1. The small lamp normally open switch can be triggered by the driven pressing piece 21 to close and conduct electricity. The small lamp 6 is connected in series with the small lamp normally open switch 61. When the connector socket 1 and the plug 2 are tightly connected, the small lamp normally open switch 61 closes to conduct the circuit and the small lamp 6 lights up. Because there are driven pressing pieces 21 on both sides of each connector socket 1, there are two switches connected in series for each small lamp 6. When the connection between the plug 2 and the connector socket 1 is firm and reliable, both switches close, and the small lamp 6 circuit conducts and lights up, indicating a good connection; when any side of the connection between the plug 2 and the connector is loose, the small lamp normally open switch 61 disconnects, and the small lamp 6 goes out, indicating that it needs to be strengthened. Whether the small lamp 6 emits light can intuitively reflect whether the connection state between the plug 2 and the connector is tight and reliable, which is convenient and intuitive for operation and maintenance.

[0022] Further improved, the flame-retardant material of the housing is ABS, with a flame-retardant rating of V0. The protection rating of the housing is IP55, and it can work in an environment with a temperature range of -25°C to 50°C and a maximum altitude of 3000m. It is sturdy and durable and can be applied to a variety of working environments.

[0023] The working principle of the present utility model

[0024] When installing the plug 2, the side of the plug 2 with the card slot 31 faces the side of the fixed hook 111. At this time, the driven fixing component 11 is in an open state. Insert the plug 2 into the connector socket 1. The two sides of the plug 2 are matched with the cavities 22 adapted to the driven pressing pieces 21. Under the action of the plug 2, the driven pressing pieces 21 rotate inwardly against the elastic force of the spring 5. The driven fixing pieces continuously close. The buckle A3 on the fixed hook 111 is matched with the card slot 31 on the plug 2, and the buckle B4 on the fixed buckle 112 is matched with the buckle groove 41 on the fixed hook 111 to further strengthen the cooperation between the plug 2 and the connector socket 1. When the cooperation is tight, the small lamp 6 lights up.

[0025] When removing the plug 2, hold the fixed hook 111 with one hand and the plug 2 with the other hand. Disconnect the cooperation between the fixed buckle 112 and the fixed hook 111, and disconnect the cooperation between the fixed hook 111 and the plug 2. Rotate the fixed hook 111 in the opening direction. At this time, the driven pressing piece 21 rotates accordingly and applies a force to the plug 2 to assist the other hand in pulling out the plug 2. Since the fixed hook has a fixed hook body 23 longer than the driven pressing piece, there is a lever structure between the fixed hook 111 and the driven pressing piece 21. The driven pressing piece 21 can apply a relatively large force to the plug 2, which can reduce the effort required for the hand holding the plug 2 to overcome static friction, making it easy and convenient.

[0026] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
