DETAILED DESCRIPTION

[0027] The following detailed description and drawings of the embodiments of the present invention are used to illustrate the principle of the present invention, but cannot be used to limit the scope of the present invention, that is, the present invention is not limited to the embodiments described.

[0028] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0029] See also Figure 1 As shown, a connector with a protective cover provided by an embodiment of the utility model includes a conductor 1, a base 2 and a cover 3. The base 2 includes a main body 21 and a mounting portion 22 formed by an integral molding injection molding process with the main body 21. The mounting portion 22 is formed by the outer wall of the main body 21 extending radially outward along the main body 21. At least a part of the conductor 1 is located in the main body 21. The mounting portion 22 is provided with two connecting portions 221 arranged opposite to each other. The side wall of the connecting portion 221 is provided with a card slot 2211; the cover 3 can be detachably mounted on the base 2, and the cover 3 is provided with There is a limit portion 31 that cooperates with the slot 2211 and is engaged with the cover body 3. The cover body 3 can move in the horizontal direction under the action of external force to switch between the detached state and the assembled state relative to the base 2. When the cover body 3 is in the assembled state, the limit portion 31 cooperates with the slot 2211 and is engaged with the slot 2211, so that the cover body 3 is firmly installed on the base 2. When the cover body 3 needs to be switched from the assembled state to the detached state, press both sides of the base 2 with your hands and apply a thrust to the open end of the cover body 3, so that the cover body 3 can slide out along the extension direction of the slot 2211 until it is separated from the base 2.

[0030] See also Figure 1 and Figure 4 As shown, the conductor 1 passes through the main body 21, and the head end of the conductor 1 protrudes outside the head end of the main body 21. This design allows the conductor 1 to be quickly connected to other conductive components.

[0031] Specifically, by providing a connecting portion 221 on the mounting portion 22, and utilizing the slot 2211 on the connecting portion 221 to cooperate with the limiting portion 31 on the cover body 3, the cover body 3 can effectively shield and protect the base 2 and the conductor 1 inside it. This design can effectively prevent accidental touching of the conductor 1, especially after installing conductive components such as copper busbars, greatly reducing the risk of electric shock and ensuring the safety of operators.

[0032] In this embodiment, the cover 3 is designed to be detachable and can be switched between a detached state and an assembled state, thereby giving the connector high flexibility and adaptability. When the electrical connection operation between the conductor 1 and other conductive components is required, the operator can quickly remove the cover 3 from the base 2 without complex tools or cumbersome steps, which greatly facilitates the installation operation. At the same time, after the connection is completed, the protective state of the cover 3 can be quickly restored through a simple snap-on operation, which reduces the installation time and improves the work efficiency.

[0033] See also Figure 2 As shown, the limiting portion 31 includes a base 311, a stopper 312 and a limiting protrusion 313. The base 311, the stopper 312 and the limiting protrusion 313 are an integrated structure. The stopper 312 and the limiting protrusion 313 are respectively arranged on the same side of the base 311. When the cover body 3 is in an assembled state, the base 311 is embedded in the slot 2211, the stopper 312 abuts against one side of the connecting portion 221, and the limiting protrusion 313 abuts against the other side of the connecting portion 221. In this embodiment, the base 311, the stopper 312 and the limiting protrusion 313 are an integral part made by an integrated molding process, and the process is preferably an injection molding process. Such a design not only enhances the structural strength of the limiting portion 31, but also reduces the risk of loosening or failure of the limiting portion 31 due to poor connection between components.

[0034] In this embodiment, when the cover body 3 is in the assembled state, the base 311 is embedded in the slot 2211 to form a stable supporting point. At the same time, the stopper 312 and the limiting protrusion 313 are respectively abutted against the two sides of the connecting portion 221, effectively preventing the cover body 3 from accidentally falling off during use.

[0035] See also Figure 3As shown, the limiting protrusion 313 includes a flat surface 3131, a first inclined surface 3132 and a second inclined surface 3133. The first inclined surface 3132 and the second inclined surface 3133 are respectively located on both sides of the flat surface 3131. When the cover body 3 is in the assembled state, the first inclined surface 3132 abuts against the connecting portion 221. In this embodiment, when the cover body 3 needs to be assembled to the base 2, the limiting portion 31 on the cover body 3 is first aligned with the slot 2211 on the side wall of the connecting portion 221, and then a force is applied in the horizontal direction to cause the limiting portion 31 to be inserted into the slot 2211 and slide in the slot 2211. Since the first inclined surface 3132 and the second inclined surface 3133 are provided on the surface of the limiting protrusion 313, the first inclined surface 3132 and the second inclined surface 3133 play a guiding role. Under the action of external force, the cover body 3 and the connecting part 221 can be slightly deformed, prompting the connecting part 221 to move along the first inclined surface 3132 and the second inclined surface 3133 to abut against the stop part 312, so that the base 311 is embedded in the slot 2211, and the connecting part 221 provided with the slot 2211 is restricted between the stop part 312 and the limiting protrusion 313, thereby enhancing the installation firmness of the cover body 3 and effectively preventing the cover body 3 from falling off the base 2.

[0036] In this embodiment, a mounting hole 222 penetrating the thickness of the mounting portion 22 is formed on the mounting portion 22 , and a metal bushing 4 is disposed in the mounting hole 222 .

[0037] When the screws are directly screwed into the mounting holes 222 without taking additional measures, the screws directly act on the inner wall of the mounting holes 222. Since the mounting portion 22 is made of plastic material, the material strength, screw tightening force and other factors may easily cause the mounting portion 22 to crack, thereby affecting the overall structure of the base 2. Figure 4 As shown, the mounting hole 222 in this embodiment is provided with a metal bushing 4, and the screws no longer directly act on the inner wall of the mounting hole 222 of the mounting portion 22, but act on the stronger and stronger metal bushing 4, which greatly reduces the risk of the mounting portion 22 cracking due to excessive local force. Secondly, the metal bushing 4 itself has high wear resistance and corrosion resistance, and can maintain good performance even in long-term use or harsh environments, which helps to extend the service life of the base 2 and reduce the maintenance and replacement costs caused by damage to the mounting hole 222. It is worth mentioning that due to the presence of the metal bushing 4, the screws are easy to screw in during the installation process, reducing the risk of damaging the mounting hole 222 due to improper operation during the installation process.

[0038] See also Figure 5As shown, one side of the mounting portion 22 is provided with an annular groove 223 arranged around the main body 21, and an insulating sealing ring 5 is embedded in the annular groove 223. In this embodiment, the insulating sealing ring 5 is a silicone rubber sealing ring. With this design, when the base 2 is installed on the panel of the chassis through the mounting hole 222, the insulating sealing ring 5 is tightly matched with the chassis panel to achieve a sealing effect.

[0039] In this embodiment, at least one clamping groove 11 is provided on the surface of the conductor 1, and the clamping groove 11 is arranged in a ring shape 360° around the central axis of the conductor 1, and a part of the main body 21 is embedded in the clamping groove 11. This design can enhance the connection strength between the conductor 1 and the main body 21.

[0040] In this embodiment, the base 2 and the cover 3 are both plastic parts. Specifically, plastic is a good insulating material that can effectively isolate current and prevent electrical leakage or short circuit. In the connector, the base 2 and the cover 3 are non-conductive parts. The use of plastic materials can ensure that a good insulation barrier is formed between them and the conductor 1, thereby improving the safety of the connector.

[0041] See also Figure 6 As shown, the conductor 1 includes a first conductive part 1a and a second conductive part 1b, the first conductive part 1a and the second conductive part 1b are an integral structure, and the first conductive part 1a is cylindrical, and the second conductive part 1b is flat. Specifically, a first wiring screw hole 12 extending along the axis direction of the first conductive part 1a is provided inside the first conductive part 1a, and a second wiring screw hole 13 penetrating the thickness of the second conductive part 1b is provided on the second conductive part 1b, and the central axis of the second wiring screw hole 13 is perpendicular to the central axis of the first wiring screw hole 12.

[0042] In this embodiment, in order to prevent the conductor 1 from rotating in the main body 21 , an anti-rotation plane 14 for preventing the conductor 1 from rotating is provided on the surface of the first conductive part 1 a , and the main body 21 and the anti-rotation plane 14 are in contact.
