[0002] Male plugs are a crucial component of electrical connections, widely used in industrial equipment, household appliances, and communications devices. Their primary function is to transmit current or signals through the pins to the corresponding female plug or receptacle. A male plug typically consists of a housing, pins, and a connector. The housing provides physical protection, the pins transmit current, and the connector connects the power cord to the pins. This design enables the male plug to operate reliably in a variety of environments, meeting the needs of diverse applications.

[0003] However, existing quick-connect male and female connectors generally lack effective connection stabilization mechanisms. This can cause the plug to become loose or detach during use due to vibration, tension, or external impact, compromising the stable transmission of current or signals. For example, poor contact between the pins and the socket can result in increased contact resistance, potentially leading to short circuits or device failures. This issue not only reduces the lifespan of the male connector but can also negatively impact the safety and reliability of the device.

[0004] In view of the above problems, a quick connector male plug is proposed to solve the above problems. Utility Model Content

[0033] 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.

[0034] Reference Figure 1 - Figure 3The utility model provides an embodiment: a quick connector male plug, comprising: a shell 1 and a shell 2, a fixing assembly is installed on the outside of the shell 1 and the shell 2, the fixing assembly includes a rotating shaft 8, the rotating shaft 8 is fixedly connected to the inside of the shell 1, the outside of the rotating shaft 8 is rotatably connected to two rotating rods 9, the left end of the rotating rod 9 is fixedly connected to a paddle 12, the right end of the rotating rod 9 is fixedly connected to an insert block 11, a tension spring 10 is provided between the two rotating rods 9, the outside of the shell 2 is fixedly connected to a fixing block 13, the top and bottom of the fixing block 13 are provided with slots 14, the insert block 11 has an arc on the side close to the fixing block 13, and the insert block 11 can be inserted into the inside of the slot 14.

[0035] Specifically, in this embodiment, the outer side of the shell 1 is fixedly connected with a rotating shaft 8, the outer side of the shell 2 is fixedly connected with a fixing block 13, the outer side of the shell 2 is rotatably connected to two rotating rods 9, and a tension spring 10 is installed between the two rotating rods 9, the right end of the rotating rod 9 is fixed with an insertion block 11, and the right end of the insertion block 11 has an arc, and the top and bottom of the fixing block 13 are provided with slots 14. When the devices are not plugged together, the two insertion blocks 11 are very close to each other under the action of the tension spring 10. When the device is installed, the insertion block 11 is squeezed by the fixing block 13 and the two rotating rods 9 will separate to both sides. When the pin 7 is plugged into the socket 4, the insertion block 11 will be plugged into the slot 14 under the action of the tension spring 10. At this time, the pin 7 and the socket 4 are difficult to separate. When the device needs to be separated, just push the paddle 12 inward to pull the two insertion blocks 11 out of the slot 14, and the pin 7 and the socket 4 can be separated by both hands.

[0036] Reference Figure 1 - Figure 2 A male plug assembly is provided inside the shell 1, and the male plug assembly includes a pin 7. The pin 7 is installed inside the shell 1, and the left end of the pin 7 can be connected to the power cord. A female plug assembly is provided inside the shell 2, and the female plug assembly includes a socket 4. The socket 4 has a plurality of sockets for the pin 7 to be plugged in. The right end of the socket 4 can be connected to the power cord. A connector 3 is installed on the opposite side of the shell 1 and the shell 2.

[0037] Specifically, a pin 7 is provided inside the shell 1, and the pin 7 includes five metal pillars. The left side of the pin 7 is fixed inside the shell 1 and can be connected to the power cord installed in the connector 3. Similarly, a socket 4 is installed in the shell 2 2, and the pin 7 can be inserted into the inside of the socket 4. At the same time, the right end of the socket 4 can also be connected to the power cord. When the socket 4 is connected to the pin 7, the power cords on both sides are connected.

[0038] Reference Figure 6A sealing assembly is installed on the outside of the socket 4, and the sealing assembly includes a sealing ring 15. The inner side of the sealing ring 15 abuts against the outer side of the socket 4. The sealing ring 15 is made of rubber. The sealing ring 15 does not contact the inner wall of the outer shell 2. A rubber ring is sleeved on the outer side of the sealing ring 15, and the outer side of the sealing ring 15 abuts against the inner side of the outer shell 2.

[0039] Specifically, when the socket 4 and the pin 7 are connected, the shell 1 will be inserted into the interior of the shell 2 2 at the same time, and the outer wall of the shell 1 will abut against the inner wall of the shell 2 2 to form a first seal. A sealing ring 15 is also provided on the outside of the socket 4. The sealing ring 15 is made of rubber and can be deformed under force. The inner wall of the shell 1 will be squeezed by the sealing ring 15. When the socket 4 and the pin 7 are connected, the sealing ring 15 will tightly fill the gap between the inner wall of the shell 1 and the outer wall of the socket 4 to form a second seal.

[0040] Reference Figure 1 , Figure 5 A protective component is installed at the bottom of the shell 2, and the protective component includes a flip seat 6. The internal rotation of the flip seat 6 is connected to a sealing cover 5, and the sealing cover 5 can be sleeved on the left end of the shell 2.

[0041] Specifically, a protective component is installed at the bottom of the outer shell 2. When the device is not connected, the sealing cover 5 on the flip seat 6 can be flipped 90 degrees and placed on the left end of the outer shell 2 to prevent dust from entering and affecting the operation of the device.

[0042] Working principle: When the socket 4 and the pin 7 are connected together, the two plug blocks 11 will be pressurized by the fixed block 13 and begin to separate toward the upper and lower sides. Slots 14 are provided at the top and bottom of the fixed block 13. When the socket 4 and the pin 7 are connected, the tension spring 10 acts on the two rotating rods 9 so that the plug block 11 is just inserted into the inside of the fixed block 13, ensuring the stability of the device connection. When the pin 7 is inserted into the socket 4, the shell 1 will be pressurized by the sealing ring 15 installed on the outside of the socket 4. Finally, the shell 1 will stick to the inner wall of the shell 2 2 to complete the connection, and the cavity between the inner wall of the shell 1 and the outside of the socket 4 is filled with the sealing ring 15, ensuring the sealing inside the device and making it difficult for external dust to enter.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
