Description

Technical Field

[0001] This invention relates to the field of plug technology, and more particularly to a plug connector and its method of use. Background Technology

[0002] A plug generally refers to the connector of an electronic product and the pin of an electrical appliance. Plug connectors are generally divided into male and female plugs, and mainly serve to conduct electricity and communicate. Aviation plugs are also a type of plug, but aviation plugs have higher requirements for connection stability and sealing performance.

[0003] Currently, aviation plug connectors typically use threaded sleeves to connect the male and female plugs after they are fully inserted. However, threaded connections may loosen when exposed to vibration, and the threads may strip after repeated disassembly and reassembly, resulting in a loose connection. Threaded connections require manual tightening, which is quite troublesome when connecting a large number of plugs in batches. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by providing a plug connector and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plug connector includes a male plug and a female plug. The female plug has a slot at one end, and the slot has multiple conductive cores. The male plug has a plug portion at one end, and the plug portion has multiple conductive holes at one end. When the plug portion is inserted into the slot, the conductive cores are simultaneously inserted into the conductive holes. A sealing sleeve is fitted and fixed at one end of the female plug near the slot. A sealing ring groove is formed between one side of the sealing sleeve and the outer wall of the female plug. A sliding ring is slidably fitted at one end of the male plug near the conductive holes. A sealing ring is fixed around one side of the sliding ring and fits into the sealing ring groove. A locking rod is fixed at both ends of the sliding ring near the female plug, and a locking head is provided at one end of each locking rod. When the male plug and the female plug are tightly inserted, the two locking heads are locked onto the outer wall of one side of the sealing sleeve. Guide blocks are fixed at both ends of the sealing sleeve away from the male plug. The guide blocks are used to tighten the two locking rods.

[0007] Preferably, each side of the male plug has a sliding groove near the plug-in portion, and each side of the slip ring has a slider fixed to its inner wall, with the two sliders slidingly disposed in the two sliding grooves respectively.

[0008] Furthermore, both guide blocks have a sloping structure on one side, and the male and female plugs can be rotated after being tightly inserted to drive the locking rod to slide onto the guide block.

[0009] Preferably, the outer arc surface of the sealing sleeve is fixed with an anti-disengagement hook near the guide block, and when the card head slides onto the guide block, the card rod inserts into the anti-disengagement hook.

[0010] Furthermore, a collar is movably fitted on the female insert, and pins are fixed at both ends on one side of the collar. An insertion hole is opened on one side of the card head, and the pins are adapted to the insertion holes. A fixing ring is fixedly fitted on the female insert near the collar, and multiple elastic elements are provided between the fixing ring and the collar.

[0011] As a further embodiment of the present invention, the elastic element includes a sliding pin and a sleeve. One end of each sliding pin is fixed to one side of a fixing ring, and one end of each sleeve is fixed to one side of a collar. The other end of each sliding pin extends into the inside of the sleeve and is fixed with a limiting plate. A spring is provided on one side of each limiting plate.

[0012] A method of using a plug connector includes the following steps:

[0013] S1: Align the male connector with the female connector's slot and insert it, pressing it firmly against the slot.

[0014] S2; The sealing ring moves into the sealing ring groove, and the clamping head of the clamping rod clamps onto the outer wall of one side of the sealing sleeve:

[0015] S3: Rotate the male or female plug to change the relative position of the two locking rods. Under the squeezing action of the guide block, the locking head drives the locking rod to slide a certain distance, so that the sealing ring and the sealing ring groove are further pressed together to ensure the sealing performance.

[0016] S4: When the locking head slides onto the guide block, the locking rod engages with the anti-disengagement hook to prevent the locking rod from falling off;

[0017] S5: Loosen the collar so that it slides to one side under the action of the elastic element, and the two pins are inserted into the socket to achieve the limiting effect.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. By using the sealing ring and sealing sleeve, along with the locking rod, after the male and female plugs are tightly inserted, the locking rod is locked onto one side of the sealing sleeve, and the sealing ring is inserted into the sealing sleeve to provide an auxiliary sealing effect. At the same time, after the male and female plugs rotate relative to each other, the locking rod slides a certain distance under the action of the guide block, making the sealing ring and sealing sleeve even tighter and further improving the sealing effect.

[0020] 2. By using the pins and holes, the two pins on one side of the collar can be inserted into the holes on the side of the card head, preventing the card rod from separating from the guide block, thus achieving a limiting effect and improving stability. Attached Figure Description
