[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 connector housing with dual locking function includes an inner shell 1;

[0039] Outer shell 2, which is fitted over the inner shell 1;

[0040] Locking assembly 3, which is used to lock the inner shell 1 to the outer shell 2;

[0041] The locking assembly 3 includes a slip ring 31 slidably disposed outside the outer shell 2, the outer shell 2 is provided with a locking block 32, the inner shell 1 is provided with a locking groove 11 that cooperates with the locking block 32, the outer shell 2 is provided with a groove 21 that penetrates the side wall of the outer shell 2, a part of the locking block 32 is located in the groove 21, and another part of the locking block 32 is located in the locking groove 11. The inner side wall of the slip ring 31 positions the locking block 32 relative to the outer shell 2.

[0042] The locking assembly 3 further includes a first locking plate 12 disposed on the inner shell 1, a second locking plate 22 disposed on the outer shell 2 that cooperates with the first locking plate 12, a third locking plate 311 disposed on the slip ring 31, the second locking plate 22 being located between the first locking plate 12 and the third locking plate 311, and the locking assembly 3 further includes a locking screw that passes through the first locking plate 12, the second locking plate 22 and the third locking plate 311 in sequence.

[0043] Understandably, the locking block 32 moves up and down in the vertical direction. After a portion of the locking block 32 enters the locking groove 11, the surface of the locking block 32 away from the locking groove 11 is flush with the outer wall of the housing 2, so that the slip ring 31 can slide normally. After the slip ring 31 slides to the target position, the locking block 32 is located inside the slip ring 31, thereby using the inner wall of the slip ring 31 to position the locking block 32 and prevent the locking groove 11 from disengaging from the locking groove 11.

[0044] When unlocking is required, first move the slip ring 31 in the opposite direction to displace the locking block 32 from the slip ring 31. Then, operate the locking block 32 to disengage it from the locking groove 11, and the outer shell 2 and the inner shell 1 can be separated.

[0045] In some embodiments, an elastic element 33 is provided between the outer shell 2 and the locking block 32 to push the locking block 32 to move away from the locking groove 11. The elastic element 33 is used to automatically disengage the locking block 32 from the locking groove 11 after the slip ring 31 and the locking block 32 are misaligned, making it easier to separate the outer shell 2 from the inner shell 1.

[0046] Reference Figures 1 to 6 As shown, in some embodiments, the locking block 32 is provided with a protruding ridge 321, and the outer shell 2 is also provided with a receiving groove for accommodating the elastic member 33. The receiving groove communicates with the groove body 21. One end of the elastic member 33 contacts the protruding ridge 321, and the other end of the elastic member 33 contacts the bottom wall of the receiving groove. The elastic member 33 can be a spring. One end of the spring is bonded to the protruding ridge 321, and the other end of the spring is bonded to the bottom wall of the receiving groove.

[0047] An alternative to the elastic element 33 is an elastic sheet, which is arc-shaped. One side of the elastic sheet is fixed to the bottom wall of the receiving groove, and the other side is fixed to the protruding ridge 321. The elastic sheet can be bonded to the bottom wall of the receiving groove. The elastic sheet can be fixed to or not fixed to the protruding ridge 321. For example, the elastic sheet can contact the protruding ridge 321, or it can be bonded to the protruding ridge 321.

[0048] In some embodiments, the protruding ridge 321 and the locking block 32 are integrally formed, and the locking block 32 is provided with a weight-reducing groove 322 to reduce the weight of the locking block 32. The shape of the weight-reducing groove 322 is not limited and can be reasonably determined as needed. The weight-reducing groove 322 is only used to reduce the overall weight of the connector housing.

[0049] Reference Figures 1 to 6As shown, in some embodiments, the locking block 32 is provided with inclined surfaces 323 at both ends along the sliding direction of the slip ring 31, and the slip ring 31 is provided with driving surfaces that cooperate with the inclined surfaces 323 at both ends along the sliding direction. The driving surfaces of the slip ring 31 push the locking block 32 into the locking groove 11 through the inclined surfaces 323.

[0050] When the driving surface contacts the inclined surface 323, the inclined surface 323 divides the force exerted by the driving surface on the inclined surface 323 into two components. One component overcomes the elastic force of the elastic element 33 and pushes the locking block 32, causing a part of the locking block 32 to enter the locking groove 11.

[0051] The drive surface can also be tilted.

[0052] In some embodiments, the third locking plate 311 and the slip ring 31 are integrally formed, and the third locking plate 311 is provided with a locking screw hole that cooperates with the locking screw.

[0053] In some embodiments, the slip ring 31 is provided with a relief groove 312, and at least a portion of the second locking plate 22 is located within the relief groove 312. The slip ring 31 is also integrally provided with a protrusion, and a locking screw hole is provided on the protrusion.

[0054] In some embodiments, the first locking plate 12 and the inner shell 1 are integral structures, and the first locking plate 12 is provided with a first through hole through which the locking screw passes.

[0055] Reference Figures 1 to 6 As shown, in some embodiments, the second locking plate 22 and the outer shell 2 are integrally formed, and the second locking plate 22 is provided with a second through hole through which the locking screw passes.

[0056] In some embodiments, there are two locking screws, which are located on the front and rear sides of the housing 2, respectively.

[0057] In some embodiments, there are two locking blocks 32 and two elastic members 33, as well as two locking grooves 11 and two groove bodies 21. The two groove bodies 21 are located on the upper and lower sides of the outer shell 2, respectively. The two groove bodies 21 are located on the upper and lower sides of the inner shell 1, respectively. Each locking block 32 engages with an independent groove body 21 and locking groove 11. Each elastic member 33 supports an independent locking block 32.

[0058] 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.

[0059] 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.

[0060] 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.
