At this time, the card block 412 is plugged and matched with the card groove 312, which increases the bonding strength between the plug 3 and the socket 4, and effectively avoids the loosening of the plug-in point due to the influence of external force, thereby causing poor sealing and poor conduction at the plug-in point.

[0034] Furthermore, the maximum width of the clamping block 412 is greater than the width of an end of the clamping block 412 close to the socket body 41 .

[0035] It can be seen from the above description that the clamping block 412 and the clamping slot 312 are not easy to separate after being clamped together, so that the connection between the plug 3 and the socket 4 can be more stable.

[0036] Furthermore, the block 412 is circular.

[0037] It can be seen from the above description that providing a circular block 412 is more convenient for making a mold for the plug 3 .

[0038] Furthermore, the socket body 41 and the clamping block 412 are an integrally formed one-piece structure.

[0039] It can be seen from the above description that the one-piece structure has higher strength, can effectively prevent the block 412 from being separated from the socket body 41, and has fewer production and assembly steps, which is conducive to improving production efficiency.

[0040] Furthermore, the clamping blocks 412 are respectively disposed on both sides of the plug-in protrusion 411 , and the clamping grooves 312 are respectively disposed on both sides of the plug-in groove 311 .

[0041] It can be seen from the above description that after the plug 3 and the socket 4 are plugged in, both sides are firmly connected and the force is balanced, avoiding the plug 3 and one side of the socket 4 separating to cause poor sealing and poor conduction at the plug-in point.

[0042] Furthermore, the card slot 312 is communicated with the inner side surface of the insertion groove 311 .

[0043] Furthermore, the card slot 312 is communicated with the outer side surface of the plug 3 .

[0044] From the above description, it can be seen that the card slot 312 connects the inner side of the insertion groove 311 and the outer side of the plug 3 respectively, which can effectively reduce the width of the side wall of the plug 3, thereby reducing the overall size of the plug 3 and meeting the development trend of product miniaturization.

[0045] Furthermore, the end edge of the inserting boss 411 or the end edge of the inserting groove 311 is rounded.

[0046] It can be seen from the above description that the rounded corner structure can guide the plugging boss 411 of the plug 3 , making it easier for the plugging boss 411 to be inserted into the plugging groove 311 .

[0047] Furthermore, the socket 4 also includes a sealing ring 43 , and the sealing ring 43 is sleeved on the plug-in boss 411 .

[0048] It can be seen from the above description that the sealing ring 43 can close the assembly gap between the plug-in boss 411 and the plug-in groove 311, thereby improving the sealing performance of the plug-in joint.

[0049] Furthermore, an annular groove 413 is provided on the outer peripheral surface of the plug-in boss 411 , and the sealing ring 43 is disposed in the annular groove 413 .

[0050] It can be seen from the above description that the annular groove 413 is used to limit the position of the sealing ring 43 to prevent the sealing ring 43 from shifting or even detaching from the socket 4 .

[0051] Please refer to Figure 1 and Figure 2, Embodiment 1 of the present invention is: a plug-in connection cable, comprising a first wiring harness 1, a second wiring harness 2, a plug 3 and a socket 4; the plug 3 comprises a plug body 31 and a plurality of pin terminals 32, one end of the plug body 31 is connected to the first wiring harness 1, and the other end is provided with a concave plug-in groove 311 and a card slot 312, a plurality of pin terminals 32 are arranged in the plug-in groove 311, and the pin terminals 32 are electrically connected to the first wiring harness 1; the socket 4 comprises a socket body 41 and a plurality of jack terminals 42, one end of the socket body 41 is connected to the second wiring harness 2, and the other end is provided with a plug-in boss 411 matched with the plug-in groove 311 and a card block 412 matched with the card slot 312, a plurality of jack terminals 42 are arranged in the plug-in boss 411, and the jack terminals 42 are electrically connected to the second wiring harness 2.

[0052] Specifically, the number of pin terminals 32 and the number of wires in the first wiring harness 1 are set in a one-to-one correspondence, and the number of pin terminals 32 and the number of jack terminals 42 are set in a one-to-one correspondence. In this embodiment, the number of pin terminals 32 and the number of plug terminals 3 are both two. In other embodiments, the number of pin terminals 32 and jack terminals 42 can be set to three or more. The end surface of the plug boss 411 away from the second wiring harness 2 is provided with a mounting hole, and the jack terminal 42 is arranged in the mounting hole. One end of the pin terminal 32 is inserted into the plug body 31, and the other end protrudes from the bottom surface of the plug groove 311.

[0053] The maximum width of the block 412 is greater than the width of the end of the block 412 close to the socket body 41. In this embodiment, the block 412 is circular, and the slot 312 is adapted to the shape of the block 412. In other embodiments, the block 412 can be set to an ellipse, triangle, trapezoid or other polygon.

[0054] In order to improve the connection strength between the socket body 41 and the card block 412, the socket body 41 and the card block 412 are integrally formed into an integrated structure. The outer side of the card block 412 is flush with the outer side of the socket body 41, which improves the appearance while ensuring that the card block 412 has sufficient thickness to ensure practicality.

[0055] Blocks 412 are provided on both sides of the plugging boss 411, and slots 312 are provided on both sides of the plugging groove 311. Specifically, the two blocks 412 provided on both sides of the plugging boss 411 are symmetrically arranged, and the two slots 312 provided on both sides of the plugging groove 311 are symmetrically arranged. It is easy to understand that after the plug 3 and the socket 4 are plugged in, both sides are firmly connected and the force is balanced, so as to avoid the separation of one side of the plug 3 and the socket 4, which may cause poor sealing and poor conduction at the plugging point.

[0056] The card slot 312 is connected to the inner side of the plug groove 311, and the card slot 312 is connected to the outer side of the plug 3, that is, the card slot 312 is formed by a notch opened on the side wall of the plug 3.

[0059] The outer surface of the socket 4 is provided with an anti-slip structure 44, which is composed of a plurality of convex blocks arranged side by side. It is easy to understand that the anti-slip mechanism can increase the friction between the socket 4 and the user's hand, making it convenient for the user to plug and unplug the plug 3 and the socket 4. In other embodiments, the anti-slip structure 44 can be composed of a plurality of pits arranged in an array; or, the outer surface of the plug 3 is provided with an anti-slip structure 44, which is also feasible to be composed of a plurality of convex blocks arranged side by side or a plurality of pits arranged in an array.

[0060] Please refer to Figure 3 The second embodiment of the present invention is a further improvement on the pin terminal 32 and the socket terminal 42 based on the first embodiment, and is different from the first embodiment in that the number of the pin terminal 32 and the socket terminal 42 are both three.

[0061] In summary, the plug-in connection wire provided by the utility model can realize the connection and conduction between the first wiring harness and the second wiring harness through the plug-in groove of the plug and the plug-in boss of the socket. At this time, the card block and the card groove are plugged and matched, which increases the bonding strength of the plug and the socket, and effectively prevents the plug-in joint from loosening due to external forces, thereby causing poor sealing and poor conduction at the plug-in joint. The sealing ring can close the assembly gap between the plug-in boss and the plug-in groove, and improve the sealing of the plug-in joint.
