[0033] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0034] Example 1:

[0035] Reference Figures 1 to 4 This utility model provides a connector including a male terminal component and a female terminal component.

[0036] Structurally, the male terminal assembly includes a plug 110 and a plurality of first terminals 120, the plurality of first terminals 120 being disposed at one end of the plug 110, and a first latch 130 being connected to one side of the plug 110.

[0037] The female end assembly includes a socket 210 and a plurality of second terminals 220. The socket 210 is provided with an inner cavity for accommodating the insertion of the plug 110. The plurality of second terminals 220 are provided at the bottom of the inner cavity. A first snap-fit ​​portion 211 that cooperates with the first snap 130 is provided on one side of the socket 210.

[0038] When the plug 110 is inserted into the socket 210, the first latch 130 engages with the first latching part 211, and the first terminals 120 and the second terminals 220 contact each other, thereby ensuring a firm connection between the plug 110 and the socket 210, preventing the connector from loosening or separating during use, and improving the reliability and stability of the connector.

[0039] Meanwhile, the plug 110 and the socket 210 are sealed by a sealing ring 300, which prevents external moisture, dust or oil from entering the connector, avoids internal electrical short circuits or poor contact, improves the safety and reliability of the connector, and extends the service life of the connector.

[0040] It should be noted that the first terminals 120 can be arranged in a single row or in two rows, and the appropriate arrangement can be selected according to the user's needs.

[0041] In some preferred embodiments, the first latch 130 includes an elastic arm 131, a hook 132, and a pressing part 133. One end of the elastic arm 131 is connected to the end of the plug 110 away from the socket 210. The hook 132 is disposed at the other end of the elastic arm 131. The pressing part 133 is disposed on one side of the elastic arm 131. The front end of the socket 210 is provided with a guide groove 212 for the hook 132 to be inserted. The first engaging part 211 is disposed at one end of the guide groove 212, and the hook 132 cooperates with the first engaging part 211.

[0042] Understandably, by releasing the pressing part 133, the elastic arm 131 springs up, and the hook 132 engages with the first locking part 211 to lock the plug 110 and the socket 210; by pressing the pressing part 133, the elastic arm 131 is subjected to force and drives the hook 132 to disengage from the first locking part 211, thereby enabling the plug 110 and the socket 210 to be unlocked, making it easy to pull the plug 110 out of the socket 210.

[0043] Furthermore, the first latch 130 is integrally formed with the plug 110, thereby increasing the connection strength of the first latch 130 and improving its service life.

[0044] In some preferred embodiments, the first snap-fit ​​portion 211 is open, specifically, the first snap-fit ​​portion 211 is a snap-fit ​​hole, thereby facilitating processing and reducing production costs.

[0045] Furthermore, the hook 132 has a guide slope 134 that slopes upward from front to back. When the plug 110 is inserted into the socket 210, the guide slope 134 of the hook 132 first abuts against the front end of the guide groove 212. The front end of the guide groove 212 is subjected to the force of the hook 132. At this time, the reaction force of the front end of the guide groove 212 is applied to the guide slope 134, causing the elastic arm 131 to press down. Thus, it is convenient for the hook 132 to enter the guide groove 212 and slide along the guide groove 212 into the first engaging part 211, so that the elastic arm 131 can be pressed down without applying force to the pressing part 133.

[0046] Furthermore, the surface of the pressing part 133 has an anti-slip structure.

[0047] In some preferred embodiments, the inner side of the plug sleeve 210 is provided with a liner 230, the side of the liner 230 is provided with a first anti-mistake protrusion 231, the inner side of the plug sleeve 210 is provided with a first anti-mistake sliding groove 213, the first anti-mistake protrusion 231 cooperates with the first anti-mistake sliding groove 213, the length direction of the first anti-mistake sliding groove 213 extends along the insertion direction of the plug 110, and the insertion end of the liner 230 and the bottom wall of the plug sleeve 210 are respectively used to limit the two sides of the sealing ring 300.

[0048] Understandably, by setting the inner liner 230, during installation, the sealing ring 300 is placed in the inner cavity of the socket 210, and then the inner liner 230 is pushed to push the sealing ring 300 against the bottom wall of the socket 210. On the one hand, this facilitates the installation of the sealing ring 300, and on the other hand, it prevents the sealing ring 300 from loosening during insertion and removal, thereby improving the reliability of the connector.

[0049] It should be noted that the material of the sealing ring 300 can be rubber, silicone, fluororubber, etc., and the optimal choice can be made according to different temperature, humidity or chemical environments.

[0050] Furthermore, a second buckle 232 is provided on the outer side of the inner liner 230, and a second snap-fit ​​portion 214 is provided on the side of the insert 210. The second buckle 232 and the second snap-fit ​​portion 214 cooperate with each other. The first snap-fit ​​portion 211 and the second snap-fit ​​portion 214 are located on opposite sides of the insert 210, thereby enabling the inner liner 230 and the insert 210 to be firmly assembled and preventing the sealing ring 300 from loosening.

[0051] In some preferred embodiments, a second anti-misalignment groove 233 is provided on the inner side of the liner 230, and a second anti-misalignment protrusion 111 is provided on the side of the plug 110. The second anti-misalignment protrusion 111 cooperates with the second anti-misalignment groove 233. The length direction of the second anti-misalignment groove 233 extends along the insertion direction of the plug 110, thereby preventing mis-insertion, avoiding electrical short circuits or equipment damage caused by incorrect connection, improving the overall safety of the connector, and extending the service life of the connector.

[0052] In some preferred embodiments, the inner side of the sealing ring 300 is provided with at least two sealing lips 310. The two sealing lips 310 form a double sealing barrier. When one sealing lip 310 fails to seal due to wear or deformation, the other sealing lip 310 can still provide a certain degree of sealing protection. Moreover, the two sealing lips 310 can better adapt to the slight deformation or unevenness of the contact surface, further improving the sealing performance and effectively preventing moisture, dust or oil from entering the connector.

[0053] Furthermore, the outer side of the sealing ring 300 is provided with several protruding ribs 320. The protruding ribs 320 abut against the side wall of the insert 210. The contact between the protruding ribs 320 and the side wall of the insert 210 can increase the friction force, prevent the sealing ring 300 from shifting or loosening under vibration or impact, and better fix the sealing ring 300 in the side wall of the insert 210, ensuring the stability of the sealing ring 300. Moreover, the protruding ribs 320 can also form multiple sealing barriers, forming multi-point sealing, further improving the sealing effect.

[0054] Example 2:

[0055] Reference Figure 5and Figure 6 The difference between Embodiment 2 and Embodiment 1 is that the form of the first snap-fit ​​part 211 is different. The first snap-fit ​​part 211 in Embodiment 2 is closed. Specifically, the first snap-fit ​​part 211 is an inner groove. The guide groove 212 and the inner groove are combined to form a stepped groove, thereby sealing the side of the plug sleeve 210 and improving the waterproof and dustproof effect of the connector.

[0056] In other embodiments, the first snap-fit ​​portion 211 may also be a contour groove, the inner cavity of which is similar to the snap hook 132.

[0057] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
