Plug-in structure with high stability

Abstract

This invention provides a highly stable plug-in structure, including a connector, a connector sleeved on the connector, a wire on the connector, and a plug-in component on the connector and connected to the wire. The plug-in component includes an arc-shaped conductive element with at least one opening along its axial direction. The conductive element and the at least one opening create one or more independent elastic contact points. When the connector is mated to the connector, the conductive element is deformed by the pressure of the internal electrical contacts of the connector, ensuring stable and sufficient radial contact pressure with each insertion. After removal, the conductive element springs back to its original curvature, effectively preventing connection failure caused by permanent enlargement of the connector's inner diameter.

Description

Technical Field

[0001] This utility model relates to the field of hot-swappable plug technology, and in particular to a highly stable plug-in structure. Background Technology

[0002] Gasoline-powered drones, with their advantages of long endurance and large payload capacity, are widely used in agricultural plant protection, power line inspection, geographic surveying, logistics transportation, and border patrol. Compared to electric drones, gasoline-powered systems have a more complex structure and operate in harsher environments. Their key components (such as batteries, sensors, communication modules, and payloads) are more prone to performance degradation, failure, or the need for replacement or upgrades under long-term, high-intensity operation. Therefore, rapid, efficient, and reliable on-site maintenance and component replacement are crucial to ensuring the operational efficiency and uptime of gasoline-powered drones.

[0003] Currently, the insertion and removal of key electronic / electrical modules or mechanical functional units with electrical interfaces on gasoline-powered UAVs generally adopts a traditional fixing method. This involves connecting the inner side of the connector to the outer side of the connector seat through an interference fit, and then fixing the connector itself to the connector seat by a certain deformation. However, with repeated insertion and removal operations, the inner diameter of the connector will gradually increase, and over time, the tightness between the connector and the connector seat cannot be guaranteed, reducing the connection stability between the connector and the connector seat and posing a safety risk. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a highly stable plug-in structure, which solves the problem that the connection stability of the connector and connector will decrease after repeated plugging and unplugging in the existing technology.

[0005] According to the embodiments of this utility model, the following technical solution is adopted:

[0006] A highly stable plug-in structure includes a connector, a connector sleeved on the connector, a wire disposed on the connector, and a plug-in component disposed on the connector and connected to the wire. The plug-in component includes an arc-shaped conductive element, and the arc-shaped conductive element has at least one opening along its axial direction.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] In this solution, with the cooperation of the conductive element and at least one opening, the conductive element has one or more independent elastic contact parts. When the connector is mated with the connector base, the arc-shaped conductive element is deformed by the pressure of the internal electrical plate of the connector base, ensuring that the arc-shaped conductive element generates stable and sufficient radial contact pressure each time it is inserted. After being pulled out, the arc-shaped conductive element springs back to its original curvature, which can effectively avoid connection failure caused by permanent expansion of the inner diameter of the connector.

[0009] Preferably, there is one opening.

[0010] Preferably, the outer side of the arc-shaped conductive element is provided with several protrusions, which are distributed on both sides of the opening.

[0011] Preferably, the protrusion is spherical.

[0012] Preferably, the end of the arc-shaped conductive element near the connector has a guide bevel.

[0013] Preferably, the guide bevel portion includes a plurality of guide plates, which are arranged at intervals along the circumference of the arc-shaped conductive element.

[0014] Preferably, the end of the arc-shaped conductive element connected to the wire is bent upwards to make the arc-shaped conductive element have an L-shaped structure.

[0015] Preferably, the end of the arc-shaped conductive element away from the wire protrudes from the opening of the connector. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] This utility model embodiment proposes a highly stable plug-in structure, including a connector 2, a connector 1 sleeved on the connector 2, a wire 3 provided on the connector 1, and a plug-in component provided on the connector 1 and connected to the wire 3. The plug-in component includes an arc-shaped conductive element 4, and the arc-shaped conductive element 4 has at least one opening 401 along its axial direction.

[0022] In the embodiments of this utility model, such as Figure 3 As shown, the arc-shaped conductive element 4 has an overall arc structure or a cylindrical structure. As a conductive material, it possesses a certain deformation capability and has at least one opening 401. When multiple openings 401 are provided, they form independent elastic contact areas. When the connector 1 is mated to the connector seat 2, the arc-shaped conductive element 4 is deformed by the pressure of the internal electrical plates of the connector seat 2. This ensures that the elastic contact areas formed by the arc-shaped conductive element 4 generate stable and sufficient radial contact pressure each time it is inserted. After being pulled out, each elastic contact area of ​​the arc-shaped conductive element 4 springs back to its original curvature, effectively preventing connection failure caused by permanent expansion of the inner diameter of the connector. To ensure the strength of the connection, such as... Figure 2 As shown, the inner diameter of the cavity of connector 1 is slightly smaller than the outer diameter of connector 2, further ensuring the stability of the connection between the two. After the connection is completed, as shown... Figure 3 As shown, the inner diameter of connector 1 is fitted onto connector 2, while the arc-shaped conductive element 4 deforms and abuts against the electrical sheet inside connector 2. Preferably, to facilitate the processing and manufacturing of the arc-shaped conductive element 4, there is only one opening 401, which can be processed by heating and bending the sheet metal.

[0023] Specifically, such as Figure 3 As shown, the outer side of the arc-shaped conductive component 4 is provided with several protrusions 402, which are distributed on both sides of the opening 401. When the arc-shaped conductive component 4 is inserted into the connector 2, the protrusions 402 of the arc-shaped conductive component 4 abut against the internal electrical sheet of the connector 2, indirectly increasing the deformation of the arc-shaped conductive component 4 and improving the effect of installing the arc-shaped conductive component 4 into the connector 2. Meanwhile, as... Figure 3 As shown, the protrusion 402 is spherical, which facilitates the insertion of the arc-shaped conductive component 4 into the connector 2. The spherical protrusion 402 will not interfere with the movement of the arc-shaped conductive component 4.

[0024] Specifically, such as Figure 3As shown, the arc-shaped conductive element 4 has a guide bevel at its end near the connector 2. This guide bevel forms an insertion structure, allowing the connector 2 to automatically slide into the inner cavity of the arc-shaped conductive element 4 under the guidance of the guide bevel, facilitating the insertion between the connector 1 and the connector 2. The guide bevel can be conical, causing the end of the arc-shaped conductive element 4 to tilt inwards radially; the tilted portion is the guide bevel. Preferably, the guide bevel includes several guide pieces 403, which are spaced apart circumferentially along the arc-shaped conductive element 4. To facilitate processing of the guide bevel, a cutting method can be used. A cut is made along the axial direction at the end of the arc-shaped conductive element 4, forming a cut. The space between the cuts is the guide piece 403. Finally, the guide piece 403 is bent, causing its end to tilt inwards towards the arc-shaped conductive element 4, thus providing guidance.

[0025] Specifically, such as Figures 1 to 3 As shown, the end of the arc-shaped conductive element 4 connected to the wire 3 is bent upwards to make the arc-shaped conductive element 4 have an L-shaped structure. If the arc-shaped conductive element 4 were straight, more axial insertion and removal space would need to be reserved to facilitate the subsequent insertion and removal of the connector 1. Therefore, when processing the arc-shaped conductive element 4, the end connected to the wire 3 is bent, and the connector 1 is also designed to correspond to the arc-shaped conductive element 4 in an L-shaped structure. This not only saves axial installation space but also facilitates manual insertion and removal of the connector 1.

[0026] Specifically, such as Figure 2 As shown, the end of the arc-shaped conductive part 4 away from the wire 3 protrudes from the opening of the connector 1. The protrusion of the end of the arc-shaped conductive part 4 is between 3mm and 5mm, preferably 5mm, which makes the insertion between the arc-shaped conductive part 4 and the connector 2 more intuitive and convenient to operate.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
