[0002] In the fields of lighting fixture manufacturing, installation, and subsequent maintenance, connecting cables are key components for achieving electrical connections between lighting fixtures and power supplies, as well as between lighting fixtures themselves. Currently, the most commonly used connection methods for lighting fixture connecting cables include the following:
[0003] The ends of the wires are directly soldered or crimped to the terminals of the light fixture. While this method provides a secure connection, it is a permanent or semi-permanent connection.
[0004] Connect using pre-fixed terminals (such as screw terminals, spring terminals, WAGO terminals, etc.) on the light fixture or the end of the connecting wire, by tightening the screw or inserting the wire.
[0005] Whether it's soldering / crimping or integrated terminal connection, when the lamp needs repair, replacement or adjustment, a tedious disassembly operation must be performed. This usually requires the use of tools to loosen the terminals, cut the connecting wires or re-strip the wires. The process is time-consuming and labor-intensive, making assembly and disassembly difficult and maintenance inconvenient. Moreover, each installation or maintenance requires repeating a series of steps such as stripping wires, aligning wires, inserting terminals, tightening screws or crimping. Each wiring requires a lot of time, which greatly reduces work efficiency. Utility Model Content

The bridge 35 is set to block the buckle 45 to prevent the buckle 45 from falling out of the slot 34 and to ensure the stability of the snap-fit between the two.
[0025] The male connector 2 includes an inner frame 4, in which a three-prong terminal 5 is installed. An outer mold sleeve 6 is fixed to one end of the inner frame 4, and the end of the three-prong terminal 5 away from the inner frame 4 is located inside the outer mold sleeve 6. A wire 7 is fixed to the end of the outer mold sleeve 6 away from the inner frame 4, and the wire 7 is fixedly connected to the three-prong terminal 5.
[0026] The connection between the main body 3 and the inner frame 4 is achieved through a specific snap-fit structure. Users only need to align and insert the parts to complete a reliable connection. When disassembling, users can easily separate the parts by simply pressing the handle area 46. This overcomes the disadvantages of traditional disassembly methods, which are difficult and time-consuming. The operation process is extremely simple and efficient, enabling quick installation and disassembly. At the same time, the connecting wires can be disconnected in seconds without any tools, which greatly improves maintenance efficiency, reduces maintenance costs, and avoids repeated wire stripping and crimping operations, protecting the wires, extending the service life of the connecting wires, and reducing wire damage.
[0027] The inner frame 4 includes a shaped frame 41 adapted to the shaped inner cavity 36. A partition 47 is fixed inside the shaped frame 41, which divides the interior of the shaped frame 41 into three placement cavities for placing the three-corner terminals 5. Three holes 43 are provided at the end of the inner frame 4 away from the three-corner terminals 5 and at the position directly opposite the three-corner terminals 5. A glue-eating hole 42 is provided at the end of the inner frame 4 near the outer mold sleeve 6.
[0028] A spring piece 44 is fixed to the flat end of the top of the irregular frame 41. A hand grip area 46 is provided at the end of the spring piece 44 near the three-prong terminal 5.

[0030] The wire 7 includes three copper cores 71, and the copper cores 71 are riveted to the crimping joint 52. The outer wall of the copper cores 71 is covered with an insulating sheath 72. The three insulating sheaths 72 are red, black and white respectively. A TPE outer sheath 73 is fitted between the outer walls of the three insulating sheaths 72.
[0031] The working principle of this utility model is as follows: The insertion process of the inner frame 4 and the connecting body 3 is as follows: Press the hand grip area 46 to press down the spring piece 44, press the hand grip area 46 into the inside of the spring piece relief groove 61. At this time, the spring piece 44 is in a horizontal position. Then insert the inner frame 4 into the inside of the irregular inner cavity 36. At this time, the horizontal ends of the three pin bodies 33 pass through the corresponding holes 43 and are connected to the three-hole opening 51 on the three-hole terminal 5. At this time, the wire 7 is connected to the pin body 33 through the three-hole terminal 5. When the hand grip area 46 is released, under the elastic reset action of the spring piece 44, the buckle 45 enters the inside of the slot 34 and is engaged.
[0032] When the connecting body 3 and the inner frame 4 need to be separated, simply press down on the hand grip area 46 to disengage the buckle 45 from the inside of the slot 34, and pull the inner frame 4 out of the connecting body 3.
