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

[0021] Please see Figure 1-4 This utility model provides a technical solution for an interlocking connection cable of an electrical connector: it includes a plug assembly 1 and a socket assembly 2. The plug assembly 1 includes a plug housing 3 and a pin group 4. The socket assembly 2 includes a socket housing 5 and a socket group 6. An interlocking structure is installed between the plug assembly 1 and the socket assembly 2. The interlocking structure includes a first protective plate 7 symmetrically installed on the left and right and a second protective plate 8 symmetrically installed on the front and back. One end of the first protective plate 7 and the second protective plate 8 are respectively hinged to the outer side of the plug housing 3. The other end of the first protective plate 7 and the second protective plate 8 are installed on the outside of the socket housing 5 through a snap-fit ​​structure 9. The outside of the socket housing 5 is also provided with a movable sliding sleeve 10 for fixing the first protective plate 7 and the second protective plate 8. The movable sliding sleeve 10 is slidably sleeved on the outside of the socket housing 5. One end of the movable sliding sleeve 10 is provided with a slot 11 for sleeved on the first protective plate 7 and the second protective plate 8.

[0022] Furthermore, the plug housing 3 is made of insulating material and has an internal cavity and a front end for insertion opening. The pin assembly 4 is fixed in the cavity of the plug housing 3. One end of the pin assembly 4 is used to connect to an external wire, and the other end extends out of the insertion opening to form a conductive end.

[0023] Furthermore, the socket housing 5 is made of insulating material, and the socket housing 5 has a plug cavity 12 that is adapted to the plug housing 3. The socket hole group 6 is fixed in the plug cavity 12 of the socket housing 5, and its position corresponds one-to-one with the pin group 4, and is used to cooperate with the conductive end of the pin group 4.

[0024] In this embodiment, when the plug assembly 1 and the socket assembly 2 are plugged in, the movable sliding sleeve 10 is first slid away from the plugging direction, so that the first protective plate 7 and the second protective plate 8 are in a movable state. Then, the conductive end of the pin group 4 of the plug assembly 1 is aligned with the socket group 6 of the socket assembly 2 and slowly inserted. After plugging in, the first protective plate 7 and the second protective plate 8 are engaged with the socket housing 5. Then, the movable sliding sleeve 10 is slid in the plugging direction, so that the slot 11 at one end of the movable sliding sleeve 10 fits the first protective plate 7 and the second protective plate 8, thereby realizing the interlocking of the plug assembly 1 and the socket assembly 2 and ensuring the stability and reliability of the connection.

[0025] Furthermore, the latch structure 9 includes a locking hook 13 fixed on the first protective plate 7 and the second protective plate 8 and a locking hole 14 located on the outer wall of the socket housing 5, the structure of the locking hole 14 being adapted to the structure of the locking hook 13.

[0026] In this embodiment, when the first protective plate 7 and the second protective plate 8 are fastened to the socket housing 5, the locking hook 13 fixed on the first protective plate 7 and the second protective plate 8 will be accurately embedded in the locking hole 14 located on the outer wall of the socket housing 5. Through the cooperation of the locking hook 13 and the locking hole 14, the stability of the connection between the plug assembly 1 and the socket assembly 2 is further enhanced, effectively preventing loosening or accidental separation during use, and providing a reliable guarantee for the safe and stable operation of the electrical connector.

[0027] Furthermore, a compression spring 15 is installed on one side of the movable sliding sleeve 10. The compression spring 15 is sleeved on the outside of the socket housing 5. The two ends of the compression spring 15 are fixedly connected to the movable sliding sleeve 10 and the socket housing 5 respectively. The outside of the movable sliding sleeve 10 is provided with anti-slip texture.

[0028] In this embodiment, when it is necessary to release the interlock between the plug assembly 1 and the socket assembly 2, the user can slide the movable sliding sleeve 10 in the opposite direction of insertion, so that the slot 11 is disengaged from the first protective plate 7 and the second protective plate 8, thereby conveniently and quickly realizing the separation operation of the plug assembly 1 and the socket assembly 2.

[0029] Furthermore, locking strips 16 are fixedly installed on both sides of the plug housing 3. The locking strips 16 are provided with evenly distributed locking holes 17. The inner wall of the insertion cavity 12 is provided with a sliding groove that matches the locking strips 16. An elastic structure 20 is installed in the sliding groove. The elastic structure 20 includes a protrusion 18 and a compression spring 19. The protrusion 18 and the compression spring 19 are installed in the cavity inside the socket housing 5. When the plug assembly 1 is inserted into the socket assembly 2, the protrusion 18 is pressed into the locking hole 17.

[0030] In this embodiment, when the plug assembly 1 is inserted into the socket assembly 2, the locking strip 16 will slide along the groove on the inner wall of the insertion cavity 12. During the sliding process, the locking hole 17 on the locking strip 16 will press the protrusion 18, thereby achieving a more stable connection between the plug assembly 1 and the socket assembly 2.

[0031] Working principle: When an electrical connection is required, the user aligns the conductive end of the pin group 4 of the plug assembly 1 with the socket group 6 of the socket assembly 2 and slowly inserts it. During insertion, the retaining strips 16 on both sides of the plug housing 3 slide along the grooves on the inner wall of the socket housing 5, and the protrusions 18 are pressed into the retaining holes 17 under the elastic force of the compression spring 19, which plays a preliminary role in positioning and fixing the plug assembly 1 and the socket assembly 2.

[0032] Simultaneously, the movable sleeve 10 is slid away from the insertion direction, making the first protective plate 7 and the second protective plate 8 movable. Then, the first protective plate 7 and the second protective plate 8 are fastened to the socket housing 5. At this time, the locking hook 13 fixed on the first protective plate 7 and the second protective plate 8 is accurately embedded in the locking hole 14 located on the outer wall of the socket housing 5. Then, the movable sleeve 10 is slid towards the insertion direction. The movable sleeve 10 overcomes the elastic force of the compression spring 15, so that the slot 11 at one end of the movable sleeve 10 fits the first protective plate 7 and the second protective plate 8. The compression spring 15 generates a reverse elastic force, so that the movable sleeve 10 is tightly fixed on the first protective plate 7 and the second protective plate 8, thereby realizing reliable interlocking between the plug assembly 1 and the socket assembly 2, ensuring that the electrical connector will not loosen or separate due to vibration, external pulling or other factors during use, and ensuring stable transmission of signals and power.

[0033] When it is necessary to disconnect, the user overcomes the elastic force of the compression spring 15 and slides the movable sleeve 10 in the opposite direction of insertion, so that the slot 11 disengages from the first protective plate 7 and the second protective plate 8. Then, the first protective plate 7 and the second protective plate 8 are opened, and the plug assembly 1 is pulled out.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover 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 process, method, article, or apparatus.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
