DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0032] like Figures 1-9 As shown, in one embodiment of the present invention, a portable Bayonet locking structure connector suitable for harsh environments includes: a female connector assembly 1, a male connector assembly 4, a male main body assembly 6 and a male connector tail tube 8.

[0033] like Figure 1-Figure 7As shown, the female connector assembly 1 includes a female connector housing 101, which is provided with a limiting groove 102 and a pair of limiting strip grooves 107. The limiting strip grooves 107 are used to cooperate with the insertion of the limiting strip plate 602 to improve the limiting and fixing effect. The limiting groove 102 is provided with a stop protrusion 103 and a stop bottom wall 104. The stop protrusion 103 can provide a locking effect and prevent the device from retreating. The stop bottom wall 104 limits the inertia of the locking point from further locking and reduces spatial sway, thereby improving the stability of the device.

[0034] like Figures 1-4 As shown, one end of the female connector housing 101 is provided with a top plane 105, which is used to make one end of the female connector housing 101 and the second connecting seal 5 evenly squeeze and contact, play a first sealing role, improve the sealing reliability of the connector in a heavy oil and heavy pollution environment, thereby improving the waterproof protection effect of the connector.

[0035] like Figure 1-Figure 2 As shown, a first connecting spring 2 and a first connecting seal 3 are provided on one side of the female connector assembly 1. The first connecting spring 2 is used to improve the stability of the structural connection and is not prone to shaking or loosening. A ridge 301 is provided on the inner side of the first connecting seal 3, which is used to cooperate with the male connector body 601 to improve the fixing effect. A groove matching the first connecting spring 2 is bored in the female connector assembly 1 for convenient placement of the first connecting spring 2. A tightening bolt 106 is threadedly connected to the female connector housing 101 to facilitate rotation by the staff. Specifically, the female connector assembly 1, the first connecting spring 2 and the first connecting seal 3 form a pluggable female connector 9.

[0036] like Figures 1-6 As shown, Figures 1-6 As shown, the male connector assembly 4 includes a male connector housing 401 having a pair of stop grooves 402 formed therein. Each of the stop grooves 402 is provided with an engaging step 403. A bar 404 and an engaging protrusion 405 are fixed to either side of the engaging step 403. The engaging protrusion 405 is provided with an interference fit with the stop groove 402. Specifically, the engaging protrusion 405 is screwed into the female stop groove 102 in the direction indicated by the indicator arrow 406. The engagement is completed after the protrusion 405 slides past the stop protrusion 103 and reaches the stop bottom wall 104.

[0037] Specifically, the engaging protrusion 405 is made of a wear-resistant material, but its hardness is slightly weaker than that of the male connector housing 401. Therefore, when the engaging point becomes worn, it can be repaired and replaced, thereby extending the service life of the male connector housing 401. The engaging step 403 has rounded corners to facilitate sliding engagement and withdrawal, and to prevent sharp corners from damaging the stop groove 402, making the stop groove 402 less susceptible to damage.

[0038] like Figures 1-6 As shown, a pair of indicator arrows 406 are provided on the male connector housing 401 to facilitate guidance to personnel and prevent incorrect rotation. A second connecting spring 407 is provided within the male connector housing 401 to enhance the secure connection and reduce the likelihood of loosening. A second connecting seal 5 is also provided between the male connector housing 401 and the male connector body 601. One side of the second connecting seal 5 is chamfered to improve the sealing performance of the device and prevent oil and water leakage.

[0039] like Figures 1-8 As shown, the male end main body assembly 6 includes a male end connector body 601. One end of the male end connector body 601 is chamfered to prevent damage to the components when the female and male ends are plugged together, thereby increasing the service life of the device. A pair of limiting strips 602 are fixed to the male end connector body 601 to improve the limiting effect. A boss 603 is fixed to the male end connector body 601. A screw groove 604, a potting groove 606, and a pair of first stop holes 605 are bored on the end of the male end connector body 601 away from the boss 603. These can be used with different male end connector tail pipes 8, making the device suitable for flexible installation in situations where space is limited or different wire outlet directions are required.

[0040] like Figures 1-9 As shown, an elastic structure 7 is provided between the male connector body 601 and the male connector tail tube 8. The elastic structure 7 includes a spring buckle 701. A support spring 702 is fixedly connected between the spring buckle 701 and the boss 603 to ensure that the device is uniformly stressed during use. A pair of slots 801 are bored on the male connector tail tube 8, and a second stop hole 803 is bored on the side walls of the pair of slots 801 to cooperate with the screw groove 604 and the first stop hole 605 for stop and fixation. A tail tube step 802 is installed in the male connector tail tube 8, which cooperates with one end of the male connector body 601 to play a locking and limiting function. The male connector assembly 4, the second connection seal 5, the male body assembly 6, the elastic structure 7 and the male connector tail tube 8 constitute a plug-in male connector 10.

[0041] Specifically, the female connector housing 101, the male connector housing 401, and the male connector body 601 are all made of 316L stainless steel, and are subjected to MIM technology and specific surface treatment to enable them to withstand neutral salt spray for more than 960 hours without being corroded, thereby increasing the service life of the device.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0043] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
