The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] The embodiments of the present application provide a gas-electric hybrid connector to solve the problem in the prior art that gas-electric hybrid connectors cannot be quickly disassembled.

[0030] like Figures 1 to 10 As shown in the figure, an embodiment of the present application: a pneumatic-electric hybrid connector, comprising: a male connector 1 and a female connector 2, the male connector 1 comprising a male plastic body 10, a male plastic sheath 11, a male terminal group 13, a male cable 14, a male air pipe 18, and a plastic button 15, one end of the male terminal group 13 and the male air pipe 18 being connected to the male cable 14, and the other end being disposed within the male plastic body 10, the plastic button 15 being sleeved on the outside of one end of the male air pipe 18, and the male plastic sheath 11 being fixed to a portion of the male terminal group 13 (details to be described below) and the outer periphery of the plastic button 15;

[0031] The female connector 2 includes a female plastic body 20, a female plastic sheath 22, a female terminal assembly 23, a female cable 24, an air pipe adapter 25, and a female air pipe 29. One end of the female terminal assembly 23 is connected to the female cable 24, and the other end is located within the female plastic body 20. The air pipe adapter 25 is mounted on the end of the female air pipe 29, and the female plastic sheath 22 is mounted on the outer periphery of the air pipe adapter 25 and the female terminal assembly 23.

[0032] When the male connector 1 and the female connector 2 are mated and connected, the male terminal set 13 and the female terminal set 23 are electrically connected, and the air pipe adapter 25 and the plastic button 15 are in contact.

[0033] The pneumatic-electric hybrid connector of this embodiment transmits power, signal, and gas. The air pipe adapter 25 and the large power terminal adopt a movable nesting assembly method, which can effectively reduce the mating insertion force and disperse the overall stress caused by the high strength of the cable.

[0035] Continue to refer to Figure 10 A three-stage stepped step is provided on the side of the tightening portion 151 opposite to the abutment 1513, and the stepped step includes a first step 1510, a second step 1511, and a third step 1512. The male plastic sheath 11 is provided with a plurality of ridges 110 that cooperate with the stepped step. In particular, a plurality of recessed arc portions 1520 are provided on the surface of the holding portion 152 for identifying the rotation angle. When the ridge 110 is engaged with the first step 1510, the male connector 1 and the female connector 2 are in a locked state. When the ridge 110 abuts against the second step 1511, the trachea adapter 25 is in a loosened state. When the ridge 110 abuts against the third step 1512, the trachea adapter 25 and the plastic button 15 are in a separated state.

[0036] Combine Figure 8 、 Figure 9, the trachea adapter 25 is unlocked by the plastic button 15, and after unlocking, the product can be quickly disassembled and plugged in. Specifically, a spring 16 is provided under the plastic button 15. In normal working state, the spring 16 provides force to avoid the button from being mistakenly locked during use. When the trachea needs to be pulled out in the connector application state, first press the plastic button 15. The plastic button 15 presses down the valve of the trachea adapter 25, and the trachea and the trachea adapter 25 are unlocked. The plastic button 15 and the male plastic sheath 11 are set with a three-stage contact mode, which respectively corresponds to the locked state, unlocked single-head state, and unlocked two-head state of the trachea adapter 25. The plastic button 15 can be fixed with the male plastic sheath 11 to select three state positions by rotating the angle of the handle 152.

[0037] like Figure 3 As shown, a large terminal hole 103, multiple small terminal holes 101 and an air duct 102 are provided in the plastic body 10 of the male socket. The air duct 102 is located between the large terminal hole 103 and the multiple small terminal holes 101. A circle of protrusions 106 extending toward the center are provided on the inner surface of the air duct 102 at intervals. The spring 16 is movably provided between the protrusion 106 and the tightening portion 151.

[0038] It also includes a male plastic cover 12 and a female plastic cover 21. A pair of first snap-fit portions 120 are provided on both sides of the width direction of the male plastic cover 12, and a pair of first protrusions 104 are provided on both sides of the width direction of the male plastic body 10, and the first snap-fit portions 120 are cooperated and connected with the first protrusions 104; a pair of second snap-fit portions 210 are provided on both sides of the length direction of the female plastic cover 21, and a pair of second protrusions 201 are provided on both sides of the upper side of the female plastic body 20 in the length direction, and the second snap-fit portions 210 and the second protrusions 201 are cooperated and connected.

[0039] like Figure 3 、 Figure 6 As shown, an auxiliary latch 121 is provided on one side of the male plastic cover 12 in the longitudinal direction, and a square unlocking pressing portion 105 is provided on one side of the male plastic body 10 in the longitudinal direction, which is suspended above the male plastic body 10. One end of the unlocking pressing portion 105 is crimped onto the top of the auxiliary latch 121. A third protrusion 200 is provided on one side of the female plastic body 20 in the longitudinal direction, and the other end of the unlocking pressing portion 105 is snap-fitted to the third protrusion 200. After the male connector 1 and the female connector 2 are snapped together, they are locked by the auxiliary latch 121 of the male plastic cover 12 to prevent the male plastic lock from being accidentally unlocked. When the male and female connectors need to be unlocked, first remove the male plastic cover 12, then press the lock to unlock and separate.

[0040] The female terminal block 23 includes a large power terminal slot 231, multiple small power terminal slots 232, and multiple signal terminal slots 230. The large power terminal slot 231 houses a large crown spring 27, while the small power terminal slots 232 house small crown springs 26. The male terminal block 13 includes a large power terminal pin 131, multiple small power terminal pins 132, and multiple signal terminal pins 130, which mate with the female terminal block 23. The male plastic sheath 11 is secured to the large power terminal pin 131 and the plastic button 15. The small power terminals carry a current of approximately 5A, while the large power terminals carry a current of over 250A. The large power terminals provide charging and power for the entire system, while the small power terminals provide power for the operation of individual components.

[0041] It also includes multiple screws (including a first screw 17 and a second screw 28). The male plastic sheath 11 and the male plastic body 10 are provided with multiple first screw holes 111, and the female plastic sheath 22 and the female plastic body 20 are provided with multiple second screw holes 220. Correspondingly, the screws are installed on the screw holes to fix the male plastic sheath 11 and the female plastic sheath 22 on the corresponding male plastic body 10 and the female plastic body 20.

[0042] The terminals, air pipe adapter 25 and the plastic body in this embodiment are clearance-matched. The terminals and air pipe adapter are placed in the groove of the plastic body and fixed by a matching plastic sheath. The plastic sheath and the plastic body are locked with screws. In this state, the matching position of the terminals can be corrected and matched by the guidance of the sheath and the terminal head. At the same time, the terminals and the air pipe adapter themselves are in a free state in the plastic groove. The terminal correction reduces the insertion force during matching.

[0043] Preferably, those skilled in the art may also think of providing a waterproof ring (not shown in the figure), which may be provided on the docking surface of the male plastic body and / or the female plastic body.
