With the rapid development of modern technology and the complexity of electronic equipment, the performance requirements of terminal connectors are constantly improving, facing many challenges.

[0035] The application has the following beneficial effects:

[0036] 1. In this invention, the double-ended clamping unit extends into the insertion groove after the sub-terminal and the female terminal are mated. Simultaneously, after receiving the supplied power, the double-ended clamping unit can tightly adhere to the two clamping concave surfaces and generate friction, so that the sub-terminal is firmly mated in the female terminal, thereby improving the connection stability after the sub-terminal and the female terminal are mated. At the same time, the generated friction is used to prevent loosening. Even when working in a high-vibration environment, the sub-terminal and the female terminal can maintain a tight mating. The supply module can supply power to the double-ended clamping unit.

[0037] 2. In this invention, the power supply module supplies condensed gas, which effectively replaces manual force application, making operation more labor-saving and effectively eliminating damage to the male and female terminals caused by excessive manual force, thus improving service life. Furthermore, unlike liquids, gas is non-conductive, preventing short circuits. Additionally, the condensed gas also serves a heat dissipation function.

[0038] 3. In this invention, the rigid bearing section can rotate around a fixed pivot, which improves structural stability. The flexible damping section avoids hard impact with the mating concave surface. It prevents loosening by tightly adhering to the corresponding mating concave surface and generating friction, effectively absorbing vibration forces in high-vibration environments and improving service life. The first return spring provides inward rotational kinetic energy for the two rigid bearing sections, causing the flexible damping section to initially move away from the mating concave surface, facilitating the mating operation of the sub-terminal and the female terminal.

[0039] 4. In this invention, the passive top block can move outward after receiving condensed gas in the inner cavity, and then push the two flexible top blocks to move outward. The two flexible top blocks will press against the corresponding tips respectively, and then push the two rigid bearing sections to rotate outward. Finally, the two flexible damping sections are tightly attached to the corresponding pressing concave surface and generate friction. It has the advantage of simple control method, which can be controlled and power supply can be realized by simply sending in condensed gas. The setting of the flexible top blocks can avoid hard impact with the tips and improve the structural life. The limiting contact block can collide with the passive top block to achieve the limiting function.

[0040] 5. In this invention, the second reset spring provides kinetic energy for the two passive top blocks to move inward, so that the two flexible top blocks will not contact the corresponding tips, thus avoiding obstructing the inward movement of the flexible damping section.

[0041] 6. In the present invention, the sealing top block is initially subjected to the elastic force of the sealing spring and closely abuts against the sealing step, thereby maintaining the state of separating the condensate inlet and condensate outlet; the inner block can collide with the sealing top block to prevent the sealing spring from being squeezed and damaged.

[0042] 7、In the present application, the setting of the secondary sealing ring and the primary sealing ring can improve the sealing performance.

[0043] 8、In the present application, the setting of the limiting protrusion can not only align the position of the double-end abutting unit and the abutting concave surface, but also ensure that the extension area is exposed to the outside, thereby providing operation space for the subsequent condensing gas feeding and discharging. The setting of the condensing gas inlet can feed condensing gas to the condensing gas inlet channel; the setting of the condensing gas outlet can discharge condensing gas; and the setting of the sealing plug can manually seal the condensing gas outlet.

[0082] 3. The sealing top block 72 is tightly abutted by the elastic force of the sealing spring 73 and the sealing step 74 in the initial state, thereby maintaining the state of separating the condensed gas inlet channel 62 and the condensed gas outlet channel 63.

[0083] 4. The condensed gas outlet 941 is provided with a sealing plug.

[0084] When the female terminal 11 and the male terminal 21 are inserted and fitted:

[0085] 1.

[0086] 2. The double-end abutting unit is inserted into the insertion slot 13.

[0087] 3. The external pipeline for conveying condensed gas is aligned and inserted into the condensed gas inlet 931, and the condensed gas can enter the inner channel 932, the first inner tube 933, and then enter the condensed gas channel 62, and then the condensed gas can push the sealing top block 72 to move inward, so that the condensed gas channel 62 and the condensed gas outlet channel 63 are connected; as the condensed gas continues to enter, the condensed gas fills the expansion gas cavity 53, and the expansion gas cavity 53 expands, so that the two passive top blocks 44 move outward, and the two flexible top blocks 48 are respectively pushed onto the corresponding sharp ends 49, and then the two rigid bearing segments 32 are rotated outward; so that the two flexible damping segments 33 can be tightly attached to the corresponding abutting concave surface 14 and generate friction, achieving the purpose of stabilizing the insertion and fitting of the male terminal 21 and the female terminal 11.

[0088] When the female terminal 11 and the male terminal 21 need to be separated:

[0089] 1, the sealing plug is pulled out of the condensate gas exhaust port 941; the condensate gas in the expansion gas cavity 53 can be discharged through the condensate gas outlet 63, the second inner tube 943 and the exhaust inner channel 942 and then discharged through the condensate gas exhaust port 941.

[0090] 2, the two hard bearing sections 32 rotate inward under the kinetic energy of the first reset spring 36, so that the flexible damping section 33 is away from the abutting concave surface 14 in the initial state, facilitating the force pulling out of the sub-terminal 21;

[0091] 3, the two passive top blocks 44 move inward under the kinetic energy of the second reset spring 52, so that the two flexible top blocks 48 are not in contact with the corresponding sharp end 49, avoiding hindering the inward movement of the flexible damping section 33.

[0092] 4, the sub-terminal 21 can be pulled out.
