Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a reverse anti-disengagement structure for a watertight connector plug and threaded sleeve. Background Technology

[0002] Typically, the plug housing and the screw sleeve are prone to detachment during connection, which can cause difficulties during on-site installation and affect subsequent installation. Currently, there is no good solution to this problem. The poor communication between parts is detrimental to the product's structure.

[0003] Therefore, by further designing the connection structure, two completely separate structures can be integrated into a whole during installation, which facilitates installation and fixation, making the entire installation process more convenient and efficient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a reverse anti-detachment structure for a watertight connector plug and sleeve that provides a secure connection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reverse anti-disengagement structure for a watertight connector plug and threaded sleeve, comprising a plug assembly and a socket assembly. The plug assembly includes a plug and a buffer sleeve fitted onto the front end of the plug. A plug housing and a connecting threaded sleeve that engages with the plug housing are provided between the plug assembly and the socket assembly. The plug housing has an installation hole adapted to the plug, and one end of the plug housing has an annular protrusion. A fan-shaped baffle is provided on one side of the annular protrusion. The connecting threaded sleeve has a first through hole and a second through hole. A slot is provided between the first through hole and the second through hole. The slot is configured such that when the plug housing passes through the connecting threaded sleeve, the fan-shaped baffle and the slot abut against each other to form a snap-fit.

[0006] The present invention is further configured such that: the diameter of the annular protrusion is larger than the second through hole and smaller than the first through hole, and the ratio of the diameter of the fan-shaped baffle to the diameter of the first through hole is 10:9.

[0007] The present invention is further configured such that the depth of the slot is less than the diameter of the sector-shaped baffle.

[0008] The present invention is further configured such that: the mounting hole is provided with a first inner hole, a second inner hole and a third inner hole in sequence, and the diameters of the first, second and third inner holes increase sequentially along the axial direction of the plug housing.

[0009] The present invention is further configured such that: the first inner hole extends to one end face of the plug housing to form a circular hole.

[0010] The beneficial effects of this utility model are:

[0011] 1. The snap-fit ​​mechanism between the plug housing and the connecting screw sleeve, using a fan-shaped baffle and a slot, effectively prevents them from separating under reverse tension. This snap-fit ​​structure provides additional stability to the connection, ensuring that the plug and socket assemblies remain tightly connected even in complex operating environments (such as under vibration or pulling), making the electrical connection and signal transmission of the entire connector more stable and reliable.

[0012] 2. The diameter of the annular protrusion is larger than that of the second through hole but smaller than that of the first through hole. This allows the plug housing to be restricted from excessive passage when passing through the connecting screw sleeve, ensuring that it engages with the connecting screw sleeve in the correct position. The ratio of the diameter of the sector-shaped baffle to the diameter of the first through hole is 10:9. This ratio provides sufficient space for the sector-shaped baffle to adjust its angle after entering the first through hole of the connecting screw sleeve, so as to accurately engage with the slot.

[0013] 3. When the depth of the slot is less than the diameter of the sector baffle, the sector baffle can be stably locked in the slot and is not easy to accidentally come out of the slot, thereby strengthening the reverse anti-disengagement capability of the entire structure and making the connection between the plug and socket assembly more stable and reliable when subjected to reverse force.

[0014] 4. The first inner hole extends to one end face of the plug housing to form a circular hole. The diameter of this first inner hole is relatively small, serving as a preliminary guide and positioning mechanism when the plug is inserted and passes through the circular hole. This allows the plug to be more accurately aligned with the mounting hole before insertion, preventing significant deviations and facilitating subsequent assembly. As the plug continues to penetrate, the gradually increasing diameter of the second and third inner holes provides more ample space for the remaining parts of the plug, allowing it to be smoothly and completely inserted into the appropriate position. Overall, this reduces the difficulty of plug installation and improves installation efficiency. Attached Figure Description

[0018] Reference Figures 1 to 2 The embodiments of this utility model will be further described below.

[0019] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0020] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0021] Figures 1 to 2 The diagram illustrates a reverse anti-dislodgement structure for a watertight connector plug and threaded sleeve, comprising a plug assembly and a socket assembly. The plug assembly includes a plug 5 and a buffer sleeve 6 fitted onto the front end of the plug 5. A plug housing 2 and a connecting threaded sleeve 11 that engages with the plug housing 2 are provided between the plug assembly and the socket assembly. The plug housing 2 has an installation hole adapted to the plug 5, and one end of the plug housing 2 has an annular protrusion 9. A fan-shaped baffle 8 is provided on one side of the annular protrusion 9. The connecting threaded sleeve 11 has a first through hole 7 and a second through hole 10. A slot 12 is provided between the plug housing 2 and the connecting screw sleeve 11. The slot 12 is configured such that when the plug housing 2 passes through the connecting screw sleeve 11, the sector baffle 8 and the slot 12 abut against each other to form a snap-fit. The snap-fit ​​between the plug housing 2 and the connecting screw sleeve 11 by the sector baffle 8 and the slot 12 can effectively prevent the two from separating when subjected to reverse pulling force. This snap-fit ​​structure provides an additional guarantee for the connection, ensuring that the plug 5 assembly and the socket assembly remain tightly connected under complex usage environments (such as under vibration, pulling, etc.), making the electrical connection and signal transmission of the entire connector more stable and reliable.

[0022] When the diameter of the annular protrusion 9 is larger than the second through hole 10 and smaller than the first through hole 7, the annular protrusion 9 restricts the excessive passage of the plug housing 2 through the connecting screw sleeve 11, ensuring that it fits the connecting screw sleeve 11 in the correct position. However, when the ratio of the diameter of the sector baffle 8 to the diameter of the first through hole 7 is greater than 10:9, the diameter of the sector baffle 8 is too large, which may prevent the plug housing 2 from being installed with the connecting screw sleeve 11 or damage the parts. When the ratio of the diameter of the sector baffle 8 to the diameter of the first through hole 7 is less than 10:9, the engagement formed by the sector baffle 8 and the connecting screw sleeve 11 is easily broken, reducing the connection strength. Therefore, the optimal ratio of the diameter of the sector baffle 8 to the diameter of the first through hole 7 is 10:9. This ratio allows the sector baffle 8 sufficient space to adjust its angle after entering the first through hole 7 of the connecting screw sleeve 11, so as to accurately engage with the slot 12.

[0023] When the depth of the slot 12 is less than the diameter of the sector baffle 8, it ensures that the sector baffle 8 can be stably locked in the slot 12 and is not easy to accidentally come out of the slot 12, thereby strengthening the reverse anti-disengagement capability of the entire structure and making the connection between the plug 5 and the socket assembly more stable and reliable when subjected to reverse force.

[0024] The first inner hole 1 extends to one end face of the plug housing 2 to form a circular hole. The rear end of the plug 5 is inserted into the plug housing 2, with part of the plug 5 protruding through the circular hole. The diameter of the first inner hole 1 is relatively small, which can play a preliminary guiding and positioning role when the plug 5 is inserted and passes through the circular hole, allowing the plug 5 to be more accurately aligned with the mounting hole before insertion, avoiding large deviations during insertion and facilitating subsequent smooth assembly. As the plug 5 continues to penetrate, the diameters of the second inner hole 3 and the third inner hole 4 gradually increase, providing more spacious accommodation for the remaining part of the plug 5, allowing the plug 5 to be inserted smoothly and completely into the appropriate position. Overall, this reduces the difficulty of installing the plug 5 and improves installation efficiency.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
