Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a mating connector. Background Technology

[0002] In electronic devices and electrical systems, mating connectors are widely used in various products as key components for circuit connection. They achieve circuit conduction through the cooperation of a male plug and a female socket, but existing technologies have significant drawbacks. First, the lack of a reliable guiding structure during insertion and removal of the male plug and female socket leads to misalignment and jamming, reducing assembly efficiency and potentially damaging internal terminals and pins. Second, existing connection methods struggle to achieve effective pre-tightening. Under external vibrations and impacts, the male plug and female socket are prone to loosening, resulting in unstable circuit connections and severely impacting equipment operation. While some connectors employ hooks and other structures to enhance connection stability, the lack of an initial pre-tightening mechanism prevents these structures from fully functioning, and the overall connection reliability still falls short of the requirements of complex operating conditions. Therefore, a mating connector technology solution that provides both precise guidance and effective pre-tightening to enhance connection stability is urgently needed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the present invention provides a plug-in connector.

[0004] The technical solution adopted by this utility model is: a plug-in connector, including a male plug and a female socket. The male plug is provided with a plug post, and the female socket is provided with a socket that engages with the plug post. A terminal is provided inside the plug post, and a pin is provided inside the socket that engages with the terminal. Guide grooves are provided on the outer walls on both sides of the socket, and guide protrusions are provided on the outer walls on both sides of the plug post. Wedge-shaped surfaces that are interference-fitted with the guide grooves are provided on both sides of the guide protrusions.

[0005] Furthermore, the wedge-shaped surface includes a guide portion at the top and an interference portion at the bottom, and the outer wall taper of the guide portion gradually tapers towards the inside of the guide ridge from the guide portion towards the interference portion.

[0006] Furthermore, the depth of the guide groove is 1 / 4 to 1 / 2 of the total length of the female socket.

[0007] Furthermore, the guide protrusion is provided with limiting steps on both sides that can abut against the steps on both sides of the guide groove.

[0008] Furthermore, the top of the guide protrusion is provided with a fastening plate that fastens to the outer wall of the female socket.

[0009] Furthermore, the top of the fastening plate is provided with rounded corners.

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

[0011] First, the guide grooves on both sides of the socket cooperate with the guide protrusions on both sides of the plug to provide precise guidance during the insertion of the male plug and the female socket, effectively avoiding misalignment and jamming during insertion and removal, greatly improving assembly efficiency, and reducing the risk of damage to internal terminals and pins due to improper insertion.

[0012] Secondly, the wedge-shaped surfaces on both sides of the guide convex strip form an interference fit with the guide groove, achieving effective pre-tightening between the male plug and the female socket. This pre-tightening effect ensures reliable fastening of the connector in the initial connection stage, laying the foundation for subsequent connection stability and effectively reducing loosening problems caused by external vibration and impact.

[0013] Furthermore, the preload effect created by the interference fit works synergistically with other auxiliary structures (such as hooks) to further enhance the connection stability of the connector. The preload provides the initial clamping force, and the auxiliary structures further restrict the relative displacement of the two, complementing each other to ensure that this mating connector maintains a stable connection even under complex operating conditions, ensuring the reliability of circuit conduction and meeting the high stability requirements of various electronic devices and electrical systems.

[0014] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0022] This utility model provides a plug-in connector.

[0023] In this embodiment, refer to Figure 1-4 The mating connector includes a male plug 1 and a female socket 2. The male plug 1 is provided with a plug post 3, and the female socket is provided with a socket 4 that mates with the plug post. The plug post is provided with a terminal 5, and the socket 4 is provided with a pin 6 that mates with the terminal. The outer walls on both sides of the socket are provided with guide grooves 8, and the outer walls on both sides of the plug post are provided with guide protrusions 9. The two sides of the guide protrusions 9 are provided with wedge-shaped surfaces 10 that are interference-fitted with the guide grooves.

[0024] In the above technical solution, the male plug's insertion post and the female socket's socket are the main connecting components. Guide grooves are provided on the outer walls of both sides of the socket, and guide protrusions are provided on the outer walls of both sides of the insertion post. Wedge-shaped surfaces are designed on both sides of the guide protrusions to interfere with the guide grooves. The shape matching of the guide grooves and guide protrusions is used to achieve guiding and positioning during the insertion and removal process. Pre-tightening is achieved by the friction generated by the interference fit between the wedge-shaped surfaces and the guide grooves.

[0025] The precise guiding structure avoids misalignment and jamming during insertion and removal, improves assembly efficiency, and reduces the risk of damage to internal terminals and pins; the interference fit achieves effective pre-tightening, reduces loosening caused by external forces, and provides a foundation for stable connector connection.

[0026] Specifically, the wedge-shaped surface includes a top guide portion 11 and a bottom interference portion 12, and the outer wall taper of the guide portion gradually narrows towards the inside of the guide ridge from the guide portion towards the interference portion.

[0027] In this embodiment, the guide portion and the interference fit of the wedge-shaped surface employ different taper designs. The outer wall taper of the guide portion gradually narrows towards the inside of the guide ridge from the guide portion towards the interference fit. During the insertion process, the guide portion first contacts the guide groove, and its larger taper guides the insertion, making it smoother. As the insertion deepens, the interference fit tightly engages with the guide groove, achieving interference pre-tightening. This design makes the insertion process smoother, reduces insertion and extraction resistance, and ensures reliable pre-tightening of the interference fit, further improving the connection reliability and stability of the connector.

[0028] Specifically, the depth of the guide groove is 1 / 4 to 1 / 2 of the total length of the female socket.

[0029] In this embodiment, the appropriate guide groove depth ensures that the guide protrusion has sufficient guiding length during the insertion process without excessively weakening the structural strength of the female socket.

[0030] Specifically, the guide protrusion is provided with limiting steps 13 on both sides, which can abut against the steps on both sides of the guide groove.

[0031] In this embodiment, the limiting steps on both sides of the guide protrusion abut against the steps on both sides of the guide groove. When the plug is inserted into place, the limiting steps restrict the movement range of the guide protrusion in the guide groove, preventing the male plug from being over-inserted or disengaged from the female socket, thus playing a limiting role.

[0032] Specifically, the top of the guide protrusion is provided with a fastening plate 14 that fastens to the outer wall of the female socket.

[0033] In this embodiment, the fastening plate extending from the top of the guide protrusion is fastened to the outer wall of the female socket after the male plug and female socket are inserted. The fastening force generated by the elastic deformation of the fastening plate further enhances the connection between the male plug and the female socket.

[0034] Specifically, the top of the fastening plate is provided with a rounded corner of 15.

[0035] In this embodiment, the top of the fastening plate is rounded to reduce friction and collision between the fastening plate and other components during the insertion and removal of the male plug and the female socket, and to avoid scratches or damage to the components caused by sharp edges.

[0036] Please note to all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
