Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a single-core electrical connector that is not easily loosened. Background Technology

[0002] A single-core electrical connector is a type of connector used to connect two electronic devices or components, typically for transmitting electrical signals.

[0003] Single-core electrical connectors consist of a plug and a socket. There are two ways to secure the plug and socket. One method uses an interference fit between the pins and the socket to fix the plug and socket. This method is simple to operate but has lower connection strength. The other method uses screws to fix the position of the plug and socket. For example, a screw hole is provided on the socket, and a screw is provided on the plug. The screw and screw hole are used to fix the plug to the socket. This method provides high connection strength for single-core electrical connectors. However, because this connection method requires screws and screw holes, the single-core electrical connector is larger and occupies more assembly space.

[0004] Therefore, existing single-core electrical connectors suffer from low connection strength. Utility Model Content

[0005] This utility model provides a single-core electrical connector that is not easily loosened, which solves the technical problem of low connection strength of existing single-core electrical connectors.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A single-core electrical connector that is not easily loosened, including a plug;

[0008] A socket into which the plug is inserted;

[0009] and a locking device, the locking device locking the position of the plug relative to the socket;

[0010] The plug is provided with a positioning groove, and the socket is provided with an elastic positioning hook that cooperates with the positioning groove. The elastic positioning hook is evenly distributed in the socket along the circumference of the socket.

[0011] The locking device pushes the elastic positioning hook, causing the elastic positioning hook to engage with the positioning groove.

[0012] Preferably, the elastic positioning hook includes a hook body that mates with the positioning groove, and the elastic positioning hook also includes an elastic sheet. The hook body is disposed on the socket through the elastic sheet. When the elastic sheet is not under force, the distance from the end of the elastic sheet away from the socket to the axis of the socket is greater than the distance from the end of the elastic sheet in contact with the socket to the axis of the socket. The hook body is disposed at the end of the elastic sheet away from the socket.

[0013] Preferably, the elastic sheet and the socket are an integral structure, or the elastic sheet is welded to the socket.

[0014] Preferably, the hook body and the elastic sheet are an integral structure, or the hook body is welded to the elastic sheet.

[0015] Preferably, the plug is provided with a positioning ridge forming the positioning groove, the positioning ridge having an inclined surface on the side facing the socket, and the hook body having a rounded corner.

[0016] Preferably, the positioning ridge and the plug are an integral structure.

[0017] Preferably, the locking device includes a cylindrical body, the socket is provided with an external thread, the cylindrical body is provided with an internal thread that meshes with the external thread, and a positioning ring is provided at one end of the cylindrical body near the plug. The positioning ring and the cylindrical body are integrally formed, and the positioning ring extends into the cylindrical body.

[0018] Preferably, the outer wall of the cylinder has a polygonal cross-sectional shape, and the tip circle diameter of the internal thread is larger than the diameter of the inner wall of the positioning ring.

[0019] Preferably, the socket is provided with an operating part, the operating part having a polygonal cross-sectional shape, the operating part and the socket being an integral structure, the socket is also provided with a mounting plate for fixing the socket to a target position, the mounting plate and the socket being an integral structure, the mounting plate being provided with mounting holes, the mounting holes being evenly distributed on the mounting plate along the circumference of the socket, and the end of the operating part away from the plug contacting the mounting plate.

[0020] Preferably, the plug is provided with a pin, the socket is provided with a socket that mates with the plug, and the plug is also provided with a guide tube. The length of the pin protruding from the plug is less than the length of the guide tube protruding from the plug. The guide tube and the pin are located at the same end of the plug, and the pin is located inside the guide tube.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] By setting a positioning groove in the plug and a flexible positioning hook in the socket, the plug and socket can be correctly assembled during assembly using the elastic deformation of the flexible positioning hook. After the plug and socket are assembled, a locking device is used to push the flexible positioning hook to engage with the positioning groove. At this time, the locking device functions to limit the position of the flexible positioning hook, that is, the flexible positioning hook is locked by the locking device and will not disengage from the positioning groove, thus preventing the plug and socket from becoming loose.

[0023] Meanwhile, by setting up elastic positioning hooks and locking devices, there is no need to set screws on the plug or socket, thus not significantly increasing the size of the electrical connector and making the electrical connector not occupy a large space. Attached Figure Description

[0035] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0036] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0037] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0038] Reference Figures 1 to 6 As shown, a single-core electrical connector that is not easily loosened includes a plug 1;

[0039] Socket 2, the plug 1 is inserted into the socket 2;

[0040] and locking device 3, which locks the position of the plug 1 relative to the socket 2;

[0041] The plug 1 is provided with a positioning groove 11, and the socket 2 is provided with an elastic positioning hook 21 that cooperates with the positioning groove 11. The elastic positioning hook 21 is evenly distributed in the socket 2 along the circumference of the socket 2.

[0042] The locking device 3 pushes the elastic positioning hook 21, causing the elastic positioning hook 21 to engage with the positioning groove 11.

[0043] In some embodiments, the elastic positioning hook 21 includes a hook body 211 that cooperates with the positioning groove 11. The elastic positioning hook 21 also includes an elastic sheet 212. The hook body 211 is disposed on the socket 2 through the elastic sheet 212. When the elastic sheet 212 is not under force, the distance E from the end of the elastic sheet 212 away from the socket 2 to the axis of the socket 2 is greater than the distance e from the end of the elastic sheet 212 in contact with the socket 2 to the axis of the socket 2. The hook body 211 is disposed at the end of the elastic sheet 212 away from the socket 2.

[0044] In the elastic positioning hook 21, the hook body 211 will not undergo elastic deformation, only the elastic sheet 212 will undergo elastic deformation.

[0045] Understandably, when the elastic sheet 212 is not under force, the elastic positioning hook 21 is in an inclined state, and the further away from the socket 2, the farther away from the socket 2 axis. There can be multiple elastic positioning hooks 21, which are evenly arranged along the circumference of the socket 2. All elastic positioning hooks 21 form a flared shape, so that the plug 1 can be correctly assembled with the socket 2.

[0046] It can be understood that when the tilt of the elastic positioning hook 21 is large enough, the plug 1 and the elastic positioning hook 21 do not contact each other when the plug 1 and the socket 2 are assembled.

[0047] In some embodiments, the elastic sheet 212 and the socket 2 are integrally formed, or the elastic sheet 212 is welded to the socket 2.

[0048] Reference Figures 1 to 6 As shown, in some embodiments, the hook body 211 and the elastic sheet 212 are an integral structure, or the hook body 211 is welded to the elastic sheet 212.

[0049] In some embodiments, the plug 1 is provided with a positioning ridge 12 forming the positioning groove 11, the positioning ridge 12 having a bevel 121 on the side facing the socket 2, and the hook 211 having a rounded corner.

[0050] Understandably, when the tilt of the elastic plate 212 is insufficient to prevent the plug 1 from contacting the elastic positioning hook 21 during assembly, or after long-term use, the tilt of the elastic positioning hook 21 is insufficient to prevent the plug 1 from contacting the elastic positioning hook 21 during assembly, in this case, when the plug 1 and the socket 2 are assembled, the plug 1 contacts the hook body 211 of the elastic positioning hook 21. In order to facilitate the assembly of the plug 1 and the socket 2, when the plug 1 and the socket 2 are assembled, the arc corner contacts the inclined surface 121, and the positioning edge 12 applies a force to the elastic positioning hook 21. This force is divided into two components by the inclined surface 121. One component causes the elastic positioning hook 21 to deform and move away from the plug 1, so that the plug 1 and the socket 2 can be assembled smoothly.

[0051] In some embodiments, the positioning ridge 12 and the plug 1 are an integral structure.

[0052] Reference Figures 1 to 6 As shown, in some embodiments, the locking device 3 includes a cylindrical body 31, the socket 2 is provided with an external thread, the cylindrical body 31 is provided with an internal thread that meshes with the external thread, and a positioning ring 311 is provided at one end of the cylindrical body 31 near the plug 1. The positioning ring 311 and the cylindrical body 31 are integrally formed, and the positioning ring 311 extends into the cylindrical body 31.

[0053] Understandably, since the elastic plate 212 of the elastic positioning hook 21 has elastic deformation capability, in order to achieve a higher connection strength between the elastic positioning hook 21 and the positioning groove 11, the elastic positioning hook 21 should be completely located within the positioning ring 311. That is, the length of the elastic positioning hook 21 is less than the length of the positioning ring 311.

[0054] Specifically, after the plug 1 and socket 2 are assembled, the cylinder 31 is rotated so that it moves closer to the plug 1. At this time, all the elastic positioning hooks 21 will enter the positioning ring 311 and be positioned by the positioning ring 311, so that the hook 211 cooperates with the positioning groove 11 to lock the plug 1 and socket 2.

[0055] When it is necessary to disconnect the plug 1 and the socket 2, rotate the cylinder 31 in the opposite direction so that the cylinder 31 moves away from the socket 2. At this time, the positioning ring 311 and the elastic positioning hook 21 will be misaligned. After the elastic positioning hook 21 and the positioning ring 311 are misaligned, the hook body 211 will disengage from the positioning groove 11 under the action of the elastic piece 212. At this time, the plug and socket 2 can be easily disconnected.

[0056] In some embodiments, the outer wall of the cylinder 31 has a polygonal cross-sectional shape, and the diameter of the crest circle of the internal thread is larger than the diameter of the inner wall of the positioning ring 311.

[0057] Reference Figures 1 to 6 As shown, in some embodiments, the socket 2 is provided with an operating part 22, the operating part 22 has a polygonal cross-sectional shape, the operating part 22 and the socket 2 are integrally formed, the socket 2 is also provided with a mounting plate 23 for fixing the socket 2 to a target position, the mounting plate 23 and the socket 2 are integrally formed, the mounting plate 23 is provided with mounting holes 24, the mounting holes 24 are evenly distributed on the mounting plate 23 along the circumference of the socket 2, and the end of the operating part 22 away from the plug 1 contacts the mounting plate 23.

[0058] Mounting plate 23 is typically used with screws to fix socket 2 to the housing of electronic device.

[0059] In some embodiments, the plug 1 is provided with a pin 13, the socket 2 is provided with a socket 25 that mates with the plug 1, and the plug 1 is also provided with a guide cylinder 14. The length of the pin 13 protruding from the plug 1 is less than the length of the guide cylinder 14 protruding from the plug 1. The guide cylinder 14 and the pin 13 are located at the same end of the plug 1, and the pin 13 is located inside the guide cylinder 14.

[0060] The guide tube 14 can be integrated with the socket 2.

[0061] Understandably, in addition to its guiding function, the guide cylinder 14 also protects the pin 13 from damage by external forces. In practice, the diameter of the pin 13 is usually small, meaning its strength is typically not high. The guide cylinder 14 prevents the pin 13 from being impacted. Furthermore, during assembly, the guide cylinder 14 ensures the pin 13 is correctly positioned relative to the socket 25, preventing misalignment and thus protecting the pin 13 from damage during assembly or disassembly of the plug 1 and socket 2. The guide cylinder 14 effectively protects the pin 13, making it less prone to damage.

[0062] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0063] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0064] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings. Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
