Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a screw-on adapter female terminal. Background Technology

[0002] Male-female connectors are made up of male and female terminals that are plugged together. They are a basic component widely used in electronic equipment, power systems and industrial automation to achieve separable electrical connections between wires, cables or circuit boards.

[0003] The conventional connection method between male and female terminals is basically a parallel connection. However, due to the influence of space, the male terminal needs to be inserted vertically to the female terminal. Therefore, the structure of the female terminal has also been modified accordingly. A connecting screw is set at the rear end of the female terminal, and the male terminal can be inserted vertically into the female terminal by connecting the male terminal vertically to the signal source.

[0004] However, with this type of female terminal, when tightening the connecting screw, the wrench needs to be inserted from the upper part of the inner cavity of the female terminal to hold the screw head for connection. Since copper busbars are installed on the circumferential wall of the inner cavity of the female terminal, the rotating wrench can easily scratch the copper busbars during the tightening process, affecting the transmission effect. Moreover, this method of tightening the connecting screw by inserting a wrench into the inner cavity of the female terminal is also very inconvenient to operate. Summary of the Invention

[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a direct screw-on adapter female terminal that is easy to operate and can effectively prevent copper busbars from being scratched.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a direct-screw type adapter female terminal, having a housing, an annular copper busbar embedded in the housing, a connecting screw fixed to the bottom of the housing, the connecting screw including a threaded section and a connecting section, an anti-touch post extending along the axis of the annular copper busbar to the outside of the annular copper busbar fixed to the center of the end face of the connecting section, a connecting cavity at the bottom of the housing, the end of the connecting section engaging with the connecting cavity, and axial planes evenly distributed around the outer circumference of the housing to facilitate rotating the housing to drive the connecting screw to rotate synchronously.

[0007] The end of the connecting section is milled flat on both sides with a radial plane, and the cavity structure of the connecting cavity matches the end of the connecting section.

[0008] The cavity side of the connecting cavity is riveted and fixed to the end face side of the connecting section.

[0009] The outer circumferential surface of the outer shell has eight axial planes evenly distributed around it.

[0010] The upper end of the anti-touch post is equipped with an insulating cap.

[0011] The beneficial effects of this utility model are: by rotating the outer shell, the connecting screw is rotated, and the wrench does not need to be inserted into the inner cavity of the outer shell. This not only makes the operation convenient, but also avoids scratching the annular copper busbar, thus ensuring the signal transmission effect. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] like Figures 1-4 The example shown is a direct-screw type adapter female terminal, which has a circular outer shell 1, an annular copper busbar 2 and a connecting screw 3. The annular copper busbar 2 is embedded in the inner cavity of the outer shell 1, and the upper end of the annular copper busbar 2 protrudes out of the upper surface of the outer shell 1. The connecting screw 3 is fixed to the bottom of the outer shell 1.

[0020] The bottom of the outer shell 1, located in the lower part of the inner cavity, has a connecting cavity 1-1. The connecting screw 3 includes a threaded section 3-1 and a connecting section 3-2. The threaded section 3-1 is connected to the signal source, and the connecting section 3-2 is engaged with the connecting cavity 1-1. Specifically, the end of the connecting section 3-2 is milled flat on both sides with an axially symmetrical radial plane 3-3. The cavity structure of the connecting cavity 1-1 matches the end of the connecting section 3-2, and the cavity side of the connecting cavity 1-1 is fixed to the end face side of the connecting section 3-2 by riveting. In this way, the connecting screw 3 is fixed to the bottom of the outer shell 1, so that the connecting screw 3 can rotate synchronously when the outer shell 1 rotates.

[0021] The connection segment 3-2 has an anti-touch post 4 fixedly connected to the center of its end face, extending along the axis of the annular copper busbar 2 to the outside of the annular copper busbar 2, and an insulating cap 5 is provided at the upper end of the anti-touch post 4 to better improve safety during use.

[0022] The outer circumferential surface of the housing 1 has eight axial planes 1-1 evenly distributed around its periphery. The symmetrical axial planes 1-1 can form a clamping surface for a rotary wrench. Thus, by simply clamping the axial planes 1-1 and rotating the housing 1, the connecting screw 3 can be rotated synchronously, achieving a vertical connection between the adapter female terminal and the signal source.

[0023] Since the connecting screw 3 is rotated by rotating the outer shell 1, the wrench does not need to be inserted into the inner cavity of the outer shell 1. This not only makes the operation convenient but also avoids scratching the annular copper busbar 2, ensuring the signal transmission effect.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
