Description

Technical Field

[0001] The utility model relates to the field of electric connectors, and more specifically, to a two-core straight metal plug connector. Background Art

[0002] With the continuous development of the new energy vehicle industry, the demand for vehicle charging speed and safety performance is getting higher and higher, which also leads to the need for improvements in many aspects such as plugs and connectors.

[0003] In the existing straight metal plug connector, the shielding component and the shell component need to be connected. However, during use, since the shielding component and the shell component are mainly fixed by a set, the shielding component may separate from the shell component when vibrating, resulting in disconnection between the shielding component and the shell component of the plug connector, making it unstable to use. At the same time, when installing cables with different wire diameters, the shielding component size of the metal plug also needs to be designed to different sizes, which increases the complexity of installation. Utility Model Content

[0004] The utility model overcomes the shortcomings of the prior art and provides a two-core straight metal plug connector, so as to solve the problem of easy disconnection between the shielding component and the shell component of the prior metal plug connector.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A two-core straight metal plug connector, comprising a housing assembly, a shielding assembly, an elastic conductor, a baffle, and a tail cover assembly;

[0007] The tail cover assembly is assembled with the housing assembly, the interior of the housing assembly is a cavity, and the shielding assembly, the elastic conductor, and the baffle are installed in the interior cavity of the housing assembly;

[0008] An elastic conductor is provided between the shielding assembly and the housing assembly, and the baffle is installed on the top of the shielding assembly;

[0009] The shell assembly, shielding assembly, baffle plate and tail cover assembly are all connected front to back to form a cable installation channel.

[0010] By arranging an elastic conductor between the shielding component and the shell component, when relative movement occurs between the shielding component and the shell component, the elastic conductor can ensure that the shielding component and the shell component are continuously connected, thereby avoiding disconnection.

[0011] A further technical solution is that the tail cover assembly and the housing assembly are fixedly installed by means of a buckle and a fixing groove.

[0012] The combination of the buckle and the fixing groove is convenient to install and easy to disassemble.

[0013] A further technical solution is that the elastic conductor is an annular spring.

[0014] The annular spring as an elastic conductor has the following advantages. First, the annular spring is easy to install. When installing, you only need to put the annular spring on the shielding component.

[0015] Secondly, the annular spring has more contact points, which can avoid the problem of failure of a single contact point;

[0016] Finally, the annular spring has good deformation recovery performance and is suitable for long-term use without failure.

[0017] A further technical solution is that a fixing groove is provided on the shielding assembly, and the width of the fixing groove is consistent with the width of the annular spring;

[0018] A fixing groove corresponding to the position of the annular spring is arranged inside the cavity of the shell component.

[0019] A fixing groove is set on the shielding component to prevent the annular spring from moving on the shielding component. At the same time, a fixing groove corresponding to the position of the annular spring is set inside the cavity of the shell component. By setting the annular spring in the fixing groove inside the cavity of the shielding component and the shell component, the relative position between the shielding component and the shell component can be fixed by the annular spring.

[0020] A further technical solution is that the shielding assembly includes a shielding sleeve and a shielding ring;

[0021] The shielding ring is installed in the shielding sleeve.

[0022] In order to make the plug connector suitable for wires of different wire diameters, it is necessary to adjust the internal diameter of the shielding component, which is troublesome. In order to facilitate the adjustment of the internal diameter of the shielding component and achieve the effect of fixing the cable shielding wire, the shielding component is designed to be a structure consisting of a shielding sleeve and a shielding ring, wherein the inner diameter of the shielding ring can be adjusted according to wires of different wire diameters, and the gap formed between the shielding sleeve and the shielding ring can be used to fix the shielding wire.

[0023] Compared with the prior art, the utility model has at least the following beneficial effects: the utility model provides an elastic conductor between the shielding component and the shell component, so that when the shielding component and the shell component move relative to each other, the elastic conductor can ensure that the shielding component and the shell component are continuously connected, thereby avoiding disconnection. At the same time, by designing the shielding component as a structure composed of a shielding sleeve and a shielding ring, under the condition of the same installation size, the demand for replacement of wires of different sizes in new energy vehicles is met, and the utility model has a wider applicability.
