Abstract
Description
Technical Field
[0001] This utility model belongs to the field of connector technology, specifically relating to a quick-connect connector for electrical equipment. Background Technology
[0002] In the complex and high-intensity industrial environment of a metallurgical continuous casting production line, there are various pieces of equipment that play a crucial role in the smooth operation of the production process. Among them, movable operating equipment such as button boxes require operators to move their positions at any time according to the actual production situation in order to precisely control various operations. For example, the sector section of the casting machine, as a core component directly related to the quality of billet forming, requires regular replacement and maintenance due to its long-term exposure to harsh conditions of high temperature, high pressure, and high wear, in order to ensure the stable and efficient operation of the production line.
[0003] Previously, the electrical connections between these devices and other equipment on the production line generally used terminal box wiring. In practice, whenever equipment needed to be replaced, workers had to carefully disconnect all the wires in the terminal box, and then reconnect them in the same way after the equipment was replaced. This process was extremely tedious, not only consuming a lot of time and energy, but also prone to errors due to the large number of wires. Wiring errors could lead to equipment malfunctions or even more serious production accidents, negatively impacting production progress and corporate profits. Therefore, it is necessary to design a connector that is easy to plug in and out, provides stable connections, and is reliable in operation to replace the existing terminal boxes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0025] Example 1:
[0026] Please see Figure 1 - Figure 6 As shown, a quick-connect plug for electrical equipment includes:

[0034] Male connector 2 is inserted into female connector 1, and male connector 2 is provided with socket 4 sleeved on pin 3, and male connector 2 and female connector 1 are mechanically locked.
[0035] Connecting cable 5 is connected to the male connector 2.
[0036] As can be seen from the above, by setting up female connector 1, male connector 2, pin 3 and socket 4 to replace the original terminal box method for connection, female connector 1 and male connector 2 are stably connected together through pin 3 and socket 4. The connection is quick and easy to make, with a low probability of error. In actual use, the application method is more flexible, not only durable, but also easy to maintain, and can effectively improve the efficiency of grounding and unplugging when moving and replacing equipment.
[0037] Please see Figure 4 - Figure 6 As shown, the female connector 1 is connected to a connecting buckle 6, and the male connector 2 has a connecting groove 7 for the connecting buckle 6 to be inserted. The female connector 1 is locked to the male connector 2 through the connecting buckle 6 and the connecting groove 7. The connecting buckle 6 is T-shaped, and the outer wall of the connecting buckle 6 abuts against the inner wall of the connecting groove 7. When the male connector 2 is inserted into the female connector 1, not only can the pin 3 be inserted into the corresponding socket 4, but the connecting port 6 can also be inserted into the connecting groove 7. The connecting buckle 6 is a T-shaped abutment formed by a patch. When the connecting buckle 6 is inserted into the connecting groove 7, the connecting buckle 6 can deform and abut against the connecting groove 7. The friction between the connecting buckle 6 and the connecting groove 7 improves the connection stability of the female connector 1 and the male connector 2.
[0038] Example 3:
[0039] Please see Figure 1 - Figure 6 As shown, a quick-connect plug for electrical equipment includes:
[0040] A female connector 1 is connected to an electrical device, and a pin 3 is provided on the female connector 1;

[0043] As can be seen from the above, by setting up female connector 1, male connector 2, pin 3 and socket 4 to replace the original terminal box method for connection, female connector 1 and male connector 2 are stably connected together through pin 3 and socket 4. The connection is quick and easy to make, with a low probability of error. In actual use, the application method is more flexible, not only durable, but also easy to maintain, and can effectively improve the efficiency of grounding and unplugging when moving and replacing equipment.
[0044] Please see Figure 4 - Figure 6As shown, the female connector 1 is connected to a connecting buckle 6, and the male connector 2 has a connecting groove 7 for the connecting buckle 6 to be inserted. The female connector 1 is locked to the male connector 2 through the connecting buckle 6 and the connecting groove 7.

The connecting buckle 6 is a T-shaped abutment formed by a patch. When the connecting buckle 6 is inserted into the connecting groove 7, the connecting buckle 6 can deform and abut against the connecting groove 7. The friction between the connecting buckle 6 and the connecting groove 7 improves the connection stability of the female connector 1 and the male connector 2.
[0045] The insertion surfaces of the pins 3 and sockets 4 are all silver-plated. The silver plating effectively improves the connection stability of the pins 3 and sockets 4, and also enhances their wear resistance, thus better coping with the frequent insertion and removal of the pins 3 and sockets 4.
[0046] The outer shells of the female connector 1 and the male connector 2 are made of aluminum alloy or high-strength plastic, which enables the female connector 1 and the male connector 2 to be resistant to high temperature, moisture and dust.
