Their technical specifications include contact resistance, insulation resistance, withstand voltage, torque, and lifespan, similar to switches.1 Connectors achieve the connection, disconnection, or switching of electronic circuits through mechanical action. Their main function is to transmit electrical signals or energy; some also have filtering functions.

[0003] The pins in conventional electrical connectors are relatively small and easily damaged by external forces. Once damaged, the entire electrical connector needs to be replaced, resulting in high maintenance costs.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an easy-to-plug power distribution connector. Utility Model Content

[0005] The purpose of this invention is to provide an easy-to-plug power distribution connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-plug power distribution connector, comprising a male terminal and a movable pin, wherein a female terminal is inserted into the outer side of one end of the male terminal, and limiting frames are connected to both the upper and lower sides of the male terminal; the movable pin is inserted into the inner side of the male terminal near the female terminal, and an encapsulation component is inserted into the surface of the male terminal near the female terminal; the movable pin includes a pin body, a fastening ring, and a mating hole; the fastening ring is sleeved on the surface of the pin body near the male terminal, and a mating hole is formed in the middle of the inner side of the pin body near the male terminal.

[0007] Furthermore, the male terminal includes a main body, a snap-fit ​​hole, a socket, and an internal pin. The main body has snap-fit ​​holes symmetrically opened on the upper and lower surfaces of the side surface near the movable pin, and a socket is opened in the middle of the side surface of the main body near the movable pin. An internal pin is installed in the center of the socket.

[0008] Furthermore, the sockets are arranged at equal intervals in the middle of one side of the main body, and the internal pins are horizontally installed at the internal axis of the sockets.

[0009] Furthermore, the fastening rings are arranged at equal intervals on one end surface of the pin body and are provided in five sets. The inner surface structure of the mating hole matches the outer surface structure of the inner connecting pin. The inner wall surface structure of the insertion hole matches the surface structure of the end of the pin body where the fastening rings are provided.

[0010] Furthermore, the female terminal includes a secondary end body, a combination hole, a limiting groove, and a limiting tenon. The secondary end body has a combination hole inside the end closest to the male terminal, and limiting grooves are symmetrically provided on the upper and lower surfaces of the secondary end body. Moreover, a limiting tenon is provided at the end of the limiting groove away from the male terminal.

[0011] Furthermore, the inner surface structure of the combined hole matches the surface structure of the end of the pin body away from the fastening ring, the inner surface structure of the limiting groove matches the side surface structure of the limiting frame, and the end surface of the limiting frame near the limiting tenon is provided with a groove structure that matches the surface structure of one side of the limiting tenon.

[0012] Furthermore, the encapsulation component includes a structural component, a snap-fit ​​tenon, a stabilizing socket, and a sealing gasket. The structural component has snap-fit ​​tenons symmetrically arranged on the upper and lower surfaces of one side surface near the male terminal, and stabilizing sockets are equidistantly arranged in the middle of the structural component. A sealing gasket is installed on the inner wall surface of the stabilizing socket.

[0013] Furthermore, the inner surface structure of the snap-fit ​​hole matches the outer surface structure of the snap-fit ​​tenon, and the snap-fit ​​tenon and the structural component are integrated into one structure. Moreover, the structural component is embedded in one side surface of the main end body.

[0014] This utility model provides an easy-to-plug power distribution connector, which has the following advantages:

[0015] 1. This utility model features five sets of fastening rings evenly arranged at one end of the main body of the pin, and a matching insertion hole is provided in the middle of one side of the main body. This allows the male terminal to be quickly inserted and connected to the movable pin. The fastening rings ensure the tightness and firmness of the insertion structure and provide good structural sealing for the insertion and connection of the movable pin and the male terminal, minimizing internal leakage. Furthermore, the above structure ensures the structural stability of the device while allowing for easy disassembly of the movable pin and the male terminal. This facilitates quick replacement if the movable pin is damaged by external forces, thereby minimizing the maintenance cost of the entire connector.

[0016] 2. This utility model features a packaged component installed on the side of the male terminal where the movable pin is inserted. The structural component uses a snap-fit ​​tenon on one side to engage with a snap-fit ​​hole on the surface of the main body, and the structure is fixed by a snap-fit ​​structure between the components. At the same time, the movable pin is horizontally inserted into the inside of the stable socket. With the help of the sealing gasket on the inner wall of the stable socket, the structure can be prevented from loosening after the movable pin is inserted into the movable pin. The use of the sealing gasket can ensure the firmness of the connection between the movable pin and the packaged component, and also ensure a certain degree of sealing and waterproofing between the two. In addition, since the packaged component is located between the male terminal and the female terminal after the structure is inserted, it can act as a structural buffer and provide a structural seal between the male terminal and the female terminal, thereby minimizing the possibility of external water seepage.

[0017] 3. This utility model, by symmetrically setting limiting frames on the upper and lower sides of the male terminal, and symmetrically opening limiting grooves and limiting tenons on the upper and lower surfaces of the female terminal body, when the male terminal and female terminal are horizontally connected and inserted into each other, the limiting frames will slide along the inside of the limiting grooves and engage with the limiting tenons at one end, thereby forming a locking structure. By using the above structure, on the one hand, it can provide a good structural fixation without affecting the structural use of the entire connector, and avoid unnecessary structural loosening of the male and female terminals after insertion. At the same time, the simple structure of the limiting frames also makes the manufacturing cost relatively low, so as to facilitate mass production and popularization. Attached Figure Description

The movable pin 4 includes a pin body 401, a fastening ring 402, and a mating hole 403. The fastening ring 402 is sleeved on the surface of the pin body 401 on the end near the male terminal 1, and the pin body 401 is close to the male terminal 1. A mating hole 403 is provided in the middle of one end of the main body 401. Five sets of fastening rings 402 are arranged at equal intervals on one end surface of the pin body 401. The inner surface structure of the mating hole 403 matches the outer surface structure of the inner pin 104. The inner wall surface structure of the insertion hole 103 matches the surface structure of the end of the pin body 401 where the fastening rings 402 are provided. Five sets of fastening rings 402 are arranged at equal intervals on one end of the pin body 401. At the same time, an insertion hole 103 matching the structure is provided in the middle of one side of the main body 101, so that the male terminal 1 can be quickly inserted and mated with the movable pin 4.

[0027] like Figures 1 to 6As shown, the male terminal 1 includes a main body 101, a snap-fit ​​hole 102, a socket 103, and an inner pin 104. The main body 101 has snap-fit ​​holes 102 symmetrically arranged on the surface near the movable pin 4, and a socket 103 is located in the center of the surface near the movable pin 4. An inner pin 104 is installed in the center of the socket 103. The sockets 103 are equidistantly arranged in the center of one side of the main body 101, and the inner pin 104 is horizontally mounted at the inner axis of the socket 103. The female terminal 2 includes a secondary... The sub-end body 201 has a combination hole 202, a limiting groove 203, and a limiting tenon 204. The sub-end body 201 has a combination hole 202 inside the end near the male terminal 1, and the upper and lower surfaces of the sub-end body 201 have symmetrically provided limiting grooves 203. The end of the limiting groove 203 away from the male terminal 1 is provided with a limiting tenon 204. When the male terminal 1 and the female terminal 2 are horizontally connected and inserted into each other, the limiting frame 3 will slide along the inside of the limiting groove 203 and make one end engage with the limiting tenon 204 to form a locking structure.

[0028] like Figures 1 to 6 As shown, the inner surface structure of the combination hole 202 matches the surface structure of the end of the pin body 401 away from the fastening ring 402. The inner surface structure of the limiting groove 203 matches the side surface structure of the limiting frame 3. The end surface of the limiting frame 3 near the limiting tenon 204 has a groove structure that matches the surface structure of one side of the limiting tenon 204. The encapsulation component 5 includes a structural component 501, a snap-fit ​​tenon 502, a stable socket 503, and a sealing gasket 504. Snap-fit ​​tenons 502 are symmetrically arranged on the side surface of the structural component 501 near the male terminal 1. Stable sockets 503 are equidistantly arranged in the middle of the structural component 501. Furthermore, the inner wall surface of the stable socket 503 is fitted with... The inner surface structure of the sealing gasket 504 and the snap-fit ​​hole 102 matches the outer surface structure of the snap-fit ​​tenon 502. The snap-fit ​​tenon 502 and the structural component 501 are integrated into one structure. The structural component 501 is embedded on one side of the main end body 101. The structural component 501 uses the snap-fit ​​tenon 502 on one side to connect with the snap-fit ​​hole 102 on one side of the main end body 101. The structure is fixed by the snap-fit ​​structure between the structures. At the same time, the movable pin 4 is horizontally inserted into the inside of the stable socket 503.

[0029] In summary, as Figures 1 to 6As shown, when using this plug-in power distribution connector, firstly, one end of the pin body 401, which is provided with a fastening ring 402 and a mating hole 403, is horizontally inserted into the socket 103 on one side of the main body 101. At the same time, the inner pin 104 inside the socket 103 is horizontally inserted into the mating hole 403, so that the movable pin 4 and the male terminal 1 can be quickly connected and combined.

[0030] Then, the snap tenon 502 on one side of the structural component 501 is connected to the snap hole 102 on one side of the main end body 101. At the same time, one end of the movable pin 4 is horizontally passed through the inside of the stable socket 503 with the sealing gasket 504 on the inner wall. Finally, the snap tenon 502 is snapped into the inside of the snap hole 102. This allows the package 5 to quickly connect with the male terminal 1 while providing structural support and stability for the movable pin 4.

[0031] Afterwards, the holes on the side surfaces of male terminal 1 and female terminal 2 can be connected to the two sets of cables to ensure normal use. Then, the movable pin 4 on one side of male terminal 1 is horizontally inserted into the combination hole 202 inside one end of the sub-end body 201. During this process, the limiting frames 3 on the upper and lower sides of male terminal 1 will slide along the limiting grooves 203 on the upper and lower surfaces of the sub-end body 201. Finally, one end of the limiting frame 3 is engaged with the limiting tenon 204, thereby providing a limiting and locking function for the inserted male terminal 1 and female terminal 2.
