Therefore, the features defined as "first", "second", "third", "fourth", "fifth", "sixth", "seventh" and "eighth" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, the meaning of "a plurality of" is two or more than two, unless otherwise specifically defined.
[0037] In the embodiments of the present application, unless otherwise specifically defined and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0038] In one embodiment of the present application, as shown in Figures 1-7 A double-spiral high-pressure-resistant connector is provided, which comprises a male connector 100, a female connector 200 and a double locking assembly 300. The male connector 100 is formed with a boss 500 for inserting a PIN needle. The female connector 200 is formed with a female groove 600 for accommodating the boss 500. The double locking assembly 300 is arranged on the outer sidewall of the female connector 200. The double locking assembly 300 comprises a first threaded ring 310, a second threaded ring 320 and a buffer washer 330. The outer sidewall of the female connector 200 is formed with an external thread 400. The first threaded ring 310 and the second threaded ring 320 are threadedly connected to the female connector 200 in sequence along the extension direction of the external thread 400. The buffer washer 330 is sleeved on the female connector 200 and located between the first threaded ring 310 and the second threaded ring 320.
[0039] Specifically, after the connection of the male seat 100 and the connection of the female seat 200 is completed, the PIN pin on the boss 500 extends into the female groove 600 and is electrically connected with the corresponding conductive unit, the user drives the first threaded ring 310 to move to the direction of the connection of the male seat 100 to the preset position, and then drives the second threaded ring 320 to the direction of the first threaded ring 310 until the buffer washer 330 is extruded and deformed by the first threaded ring 310 and the second threaded ring 320, at this time, the buffer washer 330 generates a reverse force on the first threaded ring 310 and the second threaded ring 320, so that the first threaded ring 310 and the second threaded ring 320 are more closely contacted with the external thread 400. Compared with the prior art, the connector in the high pressure environment lacks a stable connection structure, which is prone to have a large safety hidden trouble. The connector provided in the embodiment of the utility model adopts a double threaded ring structure to fix the washer with deformation characteristics, and the reverse fixing of the first threaded ring 310 and the second threaded ring 320 is realized through the reaction force generated by the deformation of the washer. Even in the high-voltage electrical connection environment with frequent vibration, the connector can still provide stable conductive connection effect, and has good high-voltage environment adaptation performance.
[0040] In the embodiment, during the movement of the first threaded ring 310 and the second threaded ring 320 to the boss 500, the outer side wall of the connection female seat 200 can be extruded, so that the part of the connection female seat 200 close to the boss 500 can be slightly deformed. When the connection of the male seat 100 and the connection of the female seat 200 is plugged and adapted, the slight deformation can further improve the connection tightness of the male seat 100 and the female seat 200.
[0041] As shown in the drawings, Figures 1-7 In another embodiment of the utility model, the first threaded ring 310 is threadedly connected to the end of the external thread 400, and the second threaded ring 320 is provided with a gap for accommodating the buffer washer 330 between the first threaded ring 310. When the second threaded ring 320 rotates and moves to the direction of the first threaded ring 310, the second threaded ring 320 can extrude the buffer washer 330 in cooperation with the first threaded ring 310, the buffer washer 330 is deformed, and the two ends of the buffer washer 330 generate elastic forces on the first threaded ring 310 and the second threaded ring 320 respectively.
[0042] In the embodiment, the buffer washer 330 is made of insulating glue material, such as insulating silica gel, insulating rubber, etc. The use of insulating glue material is conducive to providing stable elastic reaction force, and also can realize insulation effect, further reducing the probability of occurrence of electric leakage.
[0043] As shown in the drawings, Figures 1-7As shown, in another embodiment of this utility model, the connecting female seat 200 includes a first outer shell 210 and a first inner shell 220. The first outer shell 210 is provided with a sleeve-shaped structure. The external thread 400 is formed on the outer side wall of the first outer shell 210. The female groove 600 is formed on the inner ring end of the first outer shell 210. The first inner shell 220 is installed in the inner ring of the first outer shell 210. The first inner shell 220 is provided with a first pin groove through it. There are multiple sets of the first pin grooves. The multiple sets of the first pin grooves are evenly distributed on the first inner shell 220. The extension direction of the first pin groove is consistent with the length direction of the first inner shell 220. A first gap 122 is provided between the end of the first inner shell 220 near the boss 500 and the inner wall of the female groove 600.
[0044] like Figure 3 As shown, in this embodiment, a power-connecting pin sleeve is provided in the first pin groove. When the male connector 100 and the female connector 200 are plugged in and adapted, the PIN pin can extend into the first pin groove and be elastically engaged with the power-connecting pin sleeve.
[0045] like Figures 1-7 As shown, in another embodiment of this utility model, the first outer shell 210 is configured as a circular sleeve structure.

When the first threaded ring 310 and the second threaded ring 320 are threadedly connected to the external thread 400, a second gap is formed between the flat end face 700 and the first threaded ring 310 and the second threaded ring 320. Using the flat end face 700 helps to reduce the contact area between the first threaded ring 310 and the second threaded ring 320 and the first outer shell 210, thereby reducing the resistance encountered by the first threaded ring 310 and the second threaded ring 320 during rotation, and thus improving operational convenience.
[0046] like Figures 1-7 As shown, in another embodiment of this utility model, the outer diameter of the end of the first inner shell 220 away from the female groove 600 is increased, and a first mounting groove is provided on the end of the first inner shell 210 away from the female groove 600.

On the other hand, the sealing protective ring 123 can increase the sliding friction between the first inner shell 220 and the first outer shell 210, further reducing the possibility of the first inner shell 220 and the second outer shell 210 becoming loose.
[0047] As Figures 1-7 shown, in another embodiment of the utility model, the first shell 210 is provided with the rotating clamping groove 800 on the outer side wall close to the female groove 600, the connecting male seat 100 is provided with the connecting block 900 which can be clamped and matched with the rotating clamping groove 800 on the end close to the female groove 600.
