[0001] The utility model relates to the technical field of electrical connectors, and particularly relates to an electrical connector with anti-dropping function. Background Art

[0002] An electrical connector is a component for circuit connection. Using an electrical connector can achieve good contact, reliable operation, and convenient maintenance. Whether it works reliably directly affects the normal operation of the circuit and can ensure the safe and stable operation of the entire device.

[0003] After retrieval, a patent with the Chinese patent application publication number CN208970830U discloses an electrical connector with anti-dropping function, which includes a socket, a plug, a housing, a first bolt, a second bolt, a first hinge, a second hinge, a first locking hook, and a second locking hook; the socket is provided with a first groove; a boss is fixed in the first groove; a first threaded hole and a second threaded hole are formed in the right side wall of the socket.

[0004] The above-mentioned electrical connector with anti-dropping function has the following deficiencies: Although the device improves the connection stability between the socket and the plug through bolts and locking hooks to realize an electrical connector with a double-locking function, and the device is provided with a first magnet and a second magnet to fix the first bolt, the second bolt, the first locking hook, and the second locking hook, when it is necessary to disassemble and replace the plug and the socket, it is difficult to rotate the first bolt and the second bolt due to the action of the first magnet and the second magnet, so the disassembly is relatively troublesome, and when the plug is connected to the socket, the conductive terminals are not easily aligned with the conductive copper cylinders, and forcibly installing them easily breaks the conductive terminals, greatly increasing the connection difficulty. Content of the Utility Model

[0005] The purpose of the utility model is to solve or at least alleviate the problem that when it is necessary to disassemble and replace the plug and the socket in the prior art, it is difficult to rotate the first bolt and the second bolt due to the action of the first magnet and the second magnet, and thus the disassembly is relatively troublesome.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An electrical connector with anti-dropping function, including a plug and a socket. The plug is composed of a first housing and a main body insulating layer from outside to inside. The socket is composed of a second housing and a socket insulating layer from outside to inside. A plurality of conductive terminals are arranged at the right end of the plug. A plurality of conductive holes are formed in the socket insulating layer. A plurality of the conductive terminals are all installed in a plurality of corresponding conductive holes. Two rectangular grooves are symmetrically formed at one end of the second housing. Fixing mechanisms are arranged in the two rectangular grooves.

[0007] The fixing mechanism includes two telescopic rods, both of which are fixedly installed on the top inner wall of the rectangular groove. Telescopic springs are sleeved on both telescopic rods. The bottom ends of both telescopic rods are fixedly installed with the same abutting plate. A sliding column is fixedly installed on the top outer wall of the abutting plate. A limiting mechanism is provided on the second housing.

[0008] With the above technical solution, under the automatic reset action of the telescopic spring, the abutting plate and the two plug posts are pushed downward, and then the two plug posts will move into the corresponding jacks to fix the plug and the socket, preventing the two from loosening, which can play a role in preventing the electrical connector from falling off, and is also convenient for quick disassembly and installation, and the operation is simple and convenient.

[0009] Optionally, the limiting mechanism includes two T-shaped blocks, both of which are fixedly installed on the main body insulating layer. Two T-shaped grooves are symmetrically opened at one end of the second housing, and the two T-shaped blocks are respectively slidably installed in the corresponding T-shaped grooves.

[0010] With the above technical solution, the T-shaped blocks and the T-shaped grooves can play a role in assisting installation.

[0011] Optionally, a sliding hole is opened on the second housing, and the sliding column is slidably installed in the sliding hole.

[0012] With the above technical solution, by providing the sliding hole, the sliding column can be slidably installed therein, and thus can play a role in assisting installation.

[0013] Optionally, a thread is provided on the outer surface of the upper half of the sliding column, and a nut is screwed on the thread.

[0016] With the above technical solution, when the front end of the conductive terminal touches the socket insulating layer, the conductive terminal is forced to contract into the installation groove to avoid breaking, and the buffer spring is compressed. The plug contacts the socket. At this time, the plug is rotated. When the conductive terminal rotates to the corresponding conductive hole, it is inserted into the conductive hole by the elastic force after the buffer spring is compressed, without the need to align the hole by experience, preventing the conductive terminal from breaking.

[0017] Optionally, the rectangular groove and the T-shaped groove are communicated.

[0018] With the above technical solution, since the rectangular groove and the T-shaped groove are through settings, it is convenient for installation and use.

[0019] Optionally, the T-shaped groove is smaller than the rectangular groove, and the abutting plate is slidably installed on the inner walls of both sides of the rectangular groove. By setting the rectangular groove, the abutting plate can be slidably installed therein, and then the limiting movement of the abutting plate can be carried out.
