Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figure 1 , Figure 2 , Figure 8 As shown, an all-metal housing connector includes a plug 100 and a socket 200. The housing portion of the plug 100 includes a middle shell 1d0, a plug locking tube 1h0, and a male locking nut 1j0. The exposed portion of the socket 200 includes a female insertion tube 2a0, a socket shell 2g0, and a socket locking nut 2e0.

[0035] The middle shell 1d0 is inserted and sleeved on the outer layer of one end of the plug locking tube 1h0, the male plug locking nut 1j0 is threadedly connected to the other end of the plug locking tube 1h0, the socket shell 2g0 is threadedly connected to the end of the plug tube 2a0 away from the plug 100, and the socket locking nut 2e0 is threadedly connected to the end of the socket shell 2g0 away from the plug 100.

[0036] The materials of the six components, namely the middle shell 1d0, the plug locking tube 1h0, the male plug locking nut 1j0, the female plug tube 2a0, the socket shell 2g0, and the socket locking nut 2e0, are zinc alloy or aluminum alloy A6063.

[0037] Using zinc alloy or aluminum alloy A6063 for the outer shell enhances the connector's heat dissipation, anti-interference, and durability, thus extending the connector's service life.

[0038] Comparing the product of this invention with existing plastic housing connectors reveals the following:

[0039] (1) The strength and durability of the all-metal waterproof connector are more than 20% higher than those of the traditional plastic shell;

[0040] (2) The heat dissipation effect of the all-metal waterproof connector is 10% to 30% better than that of the traditional plastic shell;

[0041] (3) All-metal waterproof connectors are more resistant to shielding interference than ordinary plastic connectors;

[0042] (4) The lifespan of the all-metal waterproof connector is more than 10% longer than that of the ordinary plastic connector.

[0043] Using zinc alloy or aluminum alloy for the outer shell enhances the connector's heat dissipation, anti-interference, and durability. Traditional plastic-shelled connectors, in harsh environments, experience excessively high internal temperatures, leading to functional degradation and aging of the plastic shell over time. Connectors with all-metal shells effectively maintain performance and extend their lifespan.

[0044] Because the outer shell of the plug 100 and socket 200, including the middle shell 1d0, plug locking tube 1h0, male locking nut 1j0, female tube 2a0, socket shell 2g0, and socket locking nut 2e0, are made of zinc alloy or aluminum alloy, the connector's heat dissipation, anti-interference, durability, and service life are greatly enhanced.

[0045] like Figure 2 , Figure 8 As shown, the plug 100 and socket 200 are respectively equipped with a plug insulating tube 1k0 and a socket insulating tube 2d0, which serve to provide insulation and waterproofing. Simultaneously, a first sealing ring 1p0 and a second sealing ring 1q0 are respectively fitted at both ends of the outer layer of the plug fixing tube 1e0; a socket sealing ring 2j0 is fitted on the outer layer of the threaded end of the mating tube 2a0. This gives the entire connector waterproof and dustproof sealing functions, effectively blocking the influence of the external environment on the internal electrical connection when locked. The plug 100 also includes a plug inner shell 1m0, and the plug locking tube 1h0 is fitted on the outer layer of the plug inner shell 1m0. The socket 200 also includes a socket inner shell 2c0, and a socket shell 2g0 is fitted on the outer layer of the socket inner shell 2c0.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9As shown, the outer shell of the plug 100 is snapped together with the insertion tube 2a0.

[0047] Specifically, the plug 100 also includes a button 1a0, a pivot 1b0 and a spring 1c0 disposed at one end of the middle shell 1d0; the pivot 1b0 passes through the middle shell 1d0 and the button 1a0, and the spring 1c0 is installed between the middle shell 1d0 and the button 1a0; the button 1a0 is snapped into connection with the insertion tube 2a0.

[0048] Specifically, the outer wall of one end of the middle shell 1d0 is provided with a mounting groove for the button 1a0. The bottom of the mounting groove is provided with a middle shell spring seat 1d1 and a spring limiting post 1d2. Two through holes, middle shell pivot holes 1d3, are provided on both sides of the mounting groove. A hook through hole 1d4 is provided radially on the outer edge of the mounting groove. The hook through hole 1d4 is provided with a notch 1d5 in a radial circular direction. The button 1a0 includes a button body 1a1, a button press part 1a2, a button spring seat 1a3, a pivot hole 1a4, and a hook part 1a5. A hook groove 2a2 is provided on the outer side of the insertion tube 2a0 near the end of the middle shell 1d0. A guide part 2a1 is provided radially near the edge of the insertion tube 2a0 in the hook groove 2a2.

[0049] In use, first place one end of the spring 1c0 inside the spring seat 1d1 of the middle shell, and then fit it onto the outer layer of the spring limiting post 1d2. At the same time, place the other end of the spring 1c0 against the button spring seat 1a3. Use the rotating shaft 1b0 to pass through the rotating shaft hole 1a4 and the rotating shaft hole 1d3 of the middle shell to make the button 1a0 rotatably connected to the middle shell 1d0. Press the button press 1a2 near one end of the spring 1c0, align the notch 1d5 with the guide part 2a1, and insert the plug 100 and the socket 200. When the hook through hole 1d4 is aligned with the hook groove 2a2, release the button. The hook part 1a5, using the action of the spring 1c0 and the rotating shaft 1b0, simultaneously inserts into the hook through hole 1d4 and the hook groove 2a2, realizing the insertion and locking of the plug 100 and the socket 200. To unlock, simply press the button press 1a2 to pull the plug 100 and the socket 200 apart. It is convenient to use.

[0050] This structure offers 30% greater locking force compared to similar plastic locking mechanisms, ensuring safety and reliability. It can be unlocked up to 10,000 times. In demanding applications, this structure guarantees a stable connection between the plug 100 and the socket 200 while providing easy unlocking or disconnection.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the rotating shaft 1b0 is made of stainless steel or brass. The button 1a0 is made of zinc alloy, aluminum alloy, or stainless steel. The spring 1c0 is made of spring steel or stainless steel.

[0052] like Figure 2 , Figure 8 As shown, the plug 100 includes at least one plug copper pin 1f0; the socket 200 includes at least one socket copper pin 2b0; the surfaces of the plug copper pin 1f0 and the socket copper pin 2b0 are coated with gold. Specifically, the surfaces of the plug copper pin 1f0 and the socket copper pin 2b0 are gold-plated. The plug 100 and the socket 200 have low resistance, high conductivity, and high oxidation resistance, ensuring stable signal or power transmission. The shape and size of the contact components are precisely designed so that the corresponding parts of the plug 100 and the socket 200 can precisely mate to achieve a tight connection.

The plug pin mounting base 1g0 is snap-fitted to the plug fixing tube 1e0, and the socket pin mounting base 2i0 is snap-fitted to the mating tube 2a0.

[0054] like Figure 2 , Figure 8 As shown, the plug 100 and socket 200 are respectively equipped with a plug wire harness locking component 1i0 and a socket wire harness locking component 2f0.
