[0036] In this embodiment, one end of the first insulating shell 1 in the second direction is provided with a plug-in outlet, which is used for the plug-in part 3 to extend outward. The other end of the first insulating shell 1 in the second direction is provided with a first cable outlet 7, which is used for the output of a first cable. The first cable is electrically connected to the plug-in part 3.

[0037] In this embodiment, the insert part 3 is a PCB board, and the electrical connection part 4 is a gold finger.

[0038] Optionally, the first elastic snap-fit ​​part 2 includes an elastic deformation part and a moving part 9 connected in sequence to form an L-shape.

[0039] Specifically, when the end of the moving part 9 away from the elastic deformation part 8 is pressed toward the direction close to the first insulating shell 1, the elastic deformation part 8 undergoes elastic deformation, and the moving part 9 moves toward the direction close to the first insulating shell 1, which can insert the mounting plate into the first snap-fit ​​groove 22, thereby realizing the tool-free installation of the connector on the mounting plate.

[0040] In this embodiment, both sides of the first snap-fit ​​groove 22 extend away from the first insulating shell 1. One side of the first snap-fit ​​groove 22 is shorter than the other side and is provided with a guide slope to facilitate the insertion installation of the tool-free connector on the mounting plate.

[0041] Optionally, the first elastic snap-fit ​​part 2 is integrally connected to the first insulating shell 1.

[0042] Specifically, the first elastic snap-fit ​​part 2 and the first insulating shell 1 adopt an integrated structure and are made of the same material.

[0043] In other embodiments, the first elastic snap-fit ​​part 2 can also be installed on the first insulating shell 1 in an installation manner. The material is not limited, as long as the elastic snap-fit ​​function is achieved.

[0044] Optionally, the end of the moving part 9 away from the elastic deformation part is formed as an operating end, and the operating end is provided with a bent part 10 extending in a direction away from the first insulating shell 1.

[0045] Specifically, the operating end is used by the user to press, and the bent part 10 is bent in the direction away from the first insulating shell 1 to form an L-shaped structure, which facilitates pressing, increases the pressing stroke, and prevents slippage.

[0046] Optionally, the first elastic snap-fit ​​part 2 is provided at one end of the first insulating shell 1, and the other end of the first insulating shell 1 opposite to it is provided with a second snap-fit ​​groove 11, which is used to snap-fit ​​with the mounting plate.

The guide part 5 is plugged into the outside of the plug-in part 18 through the guide groove 6.

[0060] Specifically, such as Figure 3 As shown, the second connector can also be tool-free installed on the second mounting plate 17 through the setting of the second elastic snap-fit ​​part 16, which is convenient for installation. Its plug part 18 extends outward from one end of the second insulating shell 15. The plug groove 19 inside the plug part 18 is for the plug plate part 3 of the first connector to be inserted, and conduction is achieved through the contact between the electrical connection terminal 20 and the electrical connection part 4.

[0061] In this embodiment, the second elastic snap-fit ​​part 16 has the same structure as the first elastic snap-fit ​​part 2, and the second connector and the first connector respectively form the female head and the male head of the connector assembly.

[0062] In this embodiment, a second cable outlet 21 is provided on the second insulating shell 15 at the other end opposite to the end where the plug-in part 18 is located. The second cable outlet 21 is used for the outlet of the second cable.

[0063] Optionally, the first mounting plate 14 and the second mounting plate 17 are respectively provided with at least two first mounting slots and at least two second mounting slots, and each first mounting slot and each second mounting slot respectively engages with a first connector and a second connector.

[0064] Specifically, at least two first connectors and at least two second connectors are respectively mounted on the first mounting plate 14 and the second mounting plate 17. The at least two first connectors are snapped onto the first mounting plate 14 and are inserted into the at least two second connectors snapped onto the second mounting plate 17 along with the first mounting plate 14 as a whole. During this process, the guide portion 5 of the first connector and the outer side of the insertion portion 18 of the second connector are used for guiding engagement. The insertion portion 18 is inserted into the guide groove 6 for insertion guidance. This guide can adaptively adjust the misalignment or gap between each first connector and each first mounting groove on the first mounting plate 14 to ensure that each insertion plate portion 3 can be accurately and conveniently inserted into a insertion groove 19, ensuring the accuracy and convenience of insertion, and enabling reliable blind mating insertion.

[0065] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
