The anti-retraction portion extends along the insertion direction and one end is bent toward the snap-fit ​​portion, while the other end is connected to the transfer conductor.

[0007] Optionally, the anti-reverse portion is bent to form at least one first contact point that contacts the outer side wall of the male connector and at least one second contact point that contacts the inner side wall of the female connector between the two ends of the anti-reverse portion.

[0008] Optionally, the snap-fit ​​portion is a groove structure, and one end of the anti-reverse portion is deflected toward the groove structure and embedded in the groove structure so that one end of the anti-reverse portion is engaged with the groove structure for blocking.

[0009] Optionally, when the male and female connectors are inserted, the outer wall of the male connector presses against the first contact point to cause the anti-retraction portion to continue extending along the insertion direction until one end of the anti-retraction portion corresponds to the position of the groove structure and is embedded in the groove structure.

[0010] Optionally, the end of the male connector is a tapered structure, the top of the tapered structure is covered with an anti-collision member, and the groove structure is formed between the anti-collision member and the bottom of the tapered structure.

[0011] Optionally, the adapter conductor is provided with a spring wire extending along the insertion direction, the spring wire being bent to form at least one third contact point contacting the outer sidewall of the male connector and at least one fourth contact point contacting the inner sidewall of the female connector.

[0012] Optionally, the snap-fit ​​portion is disposed on the inner side wall of the female connector, and the outer side wall of the male connector is provided with a transfer conductor. The anti-retraction portion extends along the insertion direction and one end is bent toward the snap-fit ​​portion, while the other end is connected to the transfer conductor.

[0035] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0036] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0037] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0038] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0039] An embodiment of this utility model provides a plug-in assembly, including a male plug 1 and a female plug 2 adapted for plugging. The outer side wall of the male plug 1 and the inner side wall of the female plug 2 are provided with a stop part 31 on one side and a locking part on the other side. One end of the stop part 31 is bent towards the locking part and cooperates with the locking part in the pull-out direction of the male plug 1 to lock the male plug 1 and the female plug 2.

[0040] In actual use, after the male connector 1 and the female connector 2 are inserted, the male connector 1 can be locked because one end of the anti-retraction part 31 can cooperate with the locking part in the direction of pulling out the male connector 1, thus avoiding the risk of the male connector 1 retracting under vibration conditions.

[0041] As a way, such as Figures 1-12 As shown, in this embodiment, the snap-fit ​​part is provided on the outer side wall of the male connector 1, and the inner side wall of the female connector 2 is provided with a transfer conductor 3. The anti-retraction part 31 extends along the insertion direction and one end is bent towards the snap-fit ​​part, and the other end is connected to the transfer conductor 3. The end of the anti-retraction part 31 bent towards the snap-fit ​​part constitutes a free end 34. The transfer conductor 3 can be fixedly connected to the wooden connector through a conventional snap-fit ​​structure.

[0042] Obviously, in other embodiments, the snap-fit ​​portion may also be provided on the inner side wall of the female connector, and the anti-retraction portion may be provided on the outer side wall of the male connector.

[0043] Furthermore, in order to enhance the conductivity of the adapter conductor 3, such as... Figure 6 , 7 As shown in Figures 10 and 11, in this embodiment, the anti-retraction portion 31 is bent to form at least one first contact 32 that contacts the outer wall of the male connector 1 and at least one second contact 33 that contacts the inner wall of the female connector 2 between the two ends of the anti-retraction portion 31. The bending arrangement can further be wavy to allow more first contacts 32 and second contacts 33 to appear.

[0044] Furthermore, considering the plugging performance and to avoid affecting the smooth plugging of components, such as... Figures 1-3 and Figures 10-11 As shown, in this embodiment, the snap-fit ​​part is a groove structure 11, and one end of the anti-retraction part 31 is bent toward the groove structure 11 and embedded in the groove structure 11 so that one end of the anti-retraction part 31 is engaged with the groove structure 11.

[0045] In this embodiment, when the male connector 1 and the female connector 2 are inserted, the outer wall of the male connector 1 presses against the first contact point 32 to cause the stop part 31 to continue to extend along the insertion direction by a distance L until one end of the stop part 31, i.e., the free end 34, corresponds to the position of the groove structure 11 and is embedded in the groove structure 11. This arrangement ensures that the stop part 31 can only cooperate with the locking part after the male connector 1 and the female connector 2 are inserted into place, which can serve as a reminder that the male connector 1 and the female connector 2 are correctly inserted.

[0046] Furthermore, in order to make the male connector 1 have the ability to prevent electric shock and at the same time facilitate the formation of the groove structure 11, such as Figures 1-3 and Figures 10-11 As shown, in this embodiment, the end of the male connector 1 is a tapered structure 13. The top 14 of the tapered structure 13 is covered with an insulating anti-contact member 12. The anti-contact member 12 and the bottom 15 of the tapered structure 13 form the above-mentioned groove structure 11. In order to facilitate the fixing and assembly of the anti-contact member 12 and enhance the anti-electric shock capability of the male connector 1, both ends of the anti-contact member 12 are also extended along the two side walls of the male connector 1.

[0047] Furthermore, such as Figures 6-7 As shown, in this embodiment, the adapter conductor 3 is provided with spring wires 35 extending along the insertion direction. The spring wires 35 are bent to form at least one third contact 36 that contacts the outer side wall of the male connector 1 and at least one fourth contact 37 that contacts the inner side wall of the female connector 2, thereby satisfying the conductivity transfer performance requirements of the adapter conductor 3. In fact, the adapter conductor 3 can be called a conductive spring or other similar names commonly used in the art. In addition, in this embodiment, multiple spring wires 35 are spaced apart, and the anti-retraction part 31 is filled between adjacent spring wires 35.

[0048] Furthermore, as a method, such as Figures 1-12 As shown, in this embodiment, the male connector 1 is a flat strip structure, and the female connector 2 is inserted into the male connector 1 in a shape that is adapted to the male connector 1.

[0049] Furthermore, in order to ensure that the female connector 2 also has the ability to prevent electric shock, and to ensure that the female connector 2 can be protected, such as... Figures 4-5 and Figures 8-12 As shown, in this embodiment, the outer side of the female connector 2 is covered with a protective shell 21, which is composed of a first shell 22 and a second shell 23 that are detachably connected.

[0050] Obviously, in some embodiments other than this one, the snap-fit ​​portion can also be provided on the inner side wall of the female connector, and the outer side wall of the male connector is provided with a transfer conductor. The anti-retraction portion extends along the insertion direction and one end is bent towards the snap-fit ​​portion, while the other end is connected to the transfer conductor.

[0051] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
