[0002] In actual work, the mechanical bonding strength of Class A cable plugs and sockets as specified in the industry standard is relatively low. When the plugs and sockets are actually removed, they may become disengaged, which can easily cause line failures. Summary of the invention

[0003] The purpose of the present invention is to address the deficiencies in the prior art and provide a sealing device for a navigation light cable plug connector, which can prevent axial displacement and radial rotation at both ends of the cable plug connector, thereby ensuring normal connection of the cable.

[0004] In order to achieve the above object, the present invention provides a sealing device for a navigation light cable plug connector, comprising:

[0005] A threaded sleeve is sleeved on the outer circumference of the cable plug connector, a raised portion is provided in the middle of the threaded sleeve, and elastic limiting portions are provided at both ends of the threaded sleeve, and the radial size of the elastic limiting portion gradually decreases from the end close to the raised portion to the end away from the raised portion;

[0008] Optionally, the elastic limiting portion includes a plurality of elastic sheets arranged along the circumferential direction, and there is a gap between adjacent elastic sheets. In a natural state, the ends of the elastic sheets gather toward the center, and the radial dimension of the elastic limiting portion is smaller than the radial dimension of the elastic ring. In a tension state, the ends of the elastic sheets expand toward the periphery, and the radial dimension of the elastic limiting portion is larger than the radial dimension of the elastic ring.

[0022] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0023] The present invention provides a sealing device for a navigation light cable plug connector, comprising:

[0024] A threaded sleeve is sleeved on the outer circumference of the cable plug connector, a raised portion is provided in the middle of the threaded sleeve, and elastic limiting portions are provided at both ends of the threaded sleeve, and the radial size of the elastic limiting portion gradually decreases from the end close to the raised portion to the end away from the raised portion;

[0025] Two lock buckles are respectively threadedly connected to the two ends of the threaded sleeve, and the inner peripheral side wall of the lock buckle is provided with a wedge block, which cooperates with the elastic limiting part;

[0026] Two elastic rings are respectively arranged on the inner sides of the elastic limiting parts, and the thickness of the elastic rings is greater than the gap between the threaded sleeve and the cable plug connector.

[0027] Optionally, the protrusion is arranged corresponding to the plug-in location of the cable plug connector.

[0028] Specifically, the sealing device includes a threaded sleeve, a locking buckle and an elastic ring, the locking buckle and the elastic ring are respectively arranged on the inner side and the outer side of the threaded sleeve. Before the cable plug connector is plugged in, the locking buckle is firstly sleeved on the plug and the socket at both ends, and the two elastic rings are respectively put into the threaded sleeve from both ends, and then the threaded sleeve is sleeved on one end of the plug; when the plug connector is plugged in, the threaded sleeve is adjusted to the connection of the plug connector, and finally the locking buckles at both ends are locked with the threaded sleeve, so that in the locking process of the locking buckle, the internal wedge block pushes the elastic ring into the gap between the threaded sleeve and the plug connector in the direction of the screwing of the locking buckle. Since the gap between the two is smaller than the thickness of the elastic ring, the elastic ring is squeezed and deformed, and is firmly pressed on the cable insulation layer of the plug connector, thereby increasing the friction between the two and preventing the plug connector from being accidentally disconnected.

[0029] Optionally, the elastic limiting portion includes a plurality of elastic sheets arranged along the circumferential direction, and there are gaps between adjacent elastic sheets. In a natural state, the ends of the elastic sheets gather toward the center, and the radial dimension of the elastic limiting portion is smaller than the radial dimension of the elastic ring. In a tension state, the ends of the elastic sheets expand toward the periphery, and the radial dimension of the elastic limiting portion is larger than the radial dimension of the elastic ring.

[0030] Specifically, the elastic limiting portion of the threaded sleeve is composed of a plurality of elastic sheets, which are arranged in a circumferential direction and have gaps between each elastic sheet, so that the elastic sheets can gather together and also expand each other, which is convenient for the disassembly and assembly of the elastic ring. When the elastic ring is squeezed and set between the threaded sleeve and the cable for a long time, the elastic ring can no longer realize the elastic deformation ability, so it needs to be removed from the threaded sleeve and replaced; when the lock buckle is locked with the threaded sleeve, the wedge block inside the lock buckle will squeeze the elastic sheet, so that the elastic sheet gathers inward, so that the elastic ring can be squeezed to the middle of the threaded sleeve, so that the elastic ring fits with the plug cable.

[0031] Optionally, the threaded sleeve is provided with an external thread between the raised portion and the elastic limiting portion.

[0032] Optionally, the protrusion extends toward the inner side of the threaded sleeve to form a flange, and the inner diameter of the flange is smaller than the outer diameter of the elastic ring.

[0033] Specifically, the raised portion forms a circle of protrusions on the outer circumference of the threaded sleeve, which facilitates the alignment of the threaded sleeve and the plug-in connector. In addition, the raised portion forms a circle of flanges on the inner side of the threaded sleeve. When the elastic ring is placed into the threaded sleeve from both ends, the two elastic rings are prevented from being fixed on the cable of one end of the plug or one end of the socket. No matter how the lock is tightened, the effect of preventing accidental disconnection cannot be achieved.

[0034] Optionally, the cross-section of the outer periphery of the lock buckle is hexagonal.

[0035] Optionally, the outer surface of the lock buckle is provided with anti-slip grooves.

[0036] Specifically, in order to push the elastic ring to the gap between the threaded sleeve and the plug connector and adjust the friction between the elastic ring and the plug connector cable to the maximum, it is necessary to lock the lock buckle on the threaded sleeve, set the cross-section of the lock buckle to a hexagon and the outer surface to have anti-slip grooves, so that it is convenient to provide a greater rotational force to the lock buckle with the help of tools.

[0037] Optionally, the radial dimension of the elastic ring gradually decreases from the middle of the threaded sleeve to the outside of the threaded sleeve.

[0038] Specifically, the elastic ring can adopt a tubular structure, and an inclined surface is set at the end of the elastic ring that contacts the wedge block. In this way, during the locking process of the lock buckle and the threaded sleeve, the wedge block squeezes the elastic limiting part, so that the internal elastic ring can gradually move toward the middle of the threaded sleeve. When the elastic ring cannot move toward the middle, the lock buckle continues to lock with the threaded sleeve, the elastic ring is squeezed and deformed, and the cross-section of the elastic ring begins to increase, filling the gap between the threaded sleeve and the cable connector, thereby increasing the friction between the elastic ring and the connector cable.

[0039] Optionally, the material of the threaded sleeve is polyvinylidene fluoride.

[0040] Specifically, the threaded casing made of polyvinylidene fluoride can achieve waterproof and dustproof effects.
