[0020] like Figures 1-4 As shown in the figure, the automotive cylinder-penetrating component proposed in this embodiment includes a base 1 and a terminal assembly.

[0021] The base 1 includes an integrally formed fixed platform portion 11 and a plug-in cylindrical portion 12. The plug-in cylindrical portion 12 extends through the fixed platform portion 11, with both ends extending from the sides of the fixed platform portion 11. The plug-in cylindrical portion 12 has a first plug-in groove and a second plug-in groove on both sides along its length, with the upper one being the first plug-in groove and the lower one being the second plug-in groove. A latching portion 122 is provided on the upper outer circumferential surface of the plug-in cylindrical portion 12. The latching portion 122 includes a "U"-shaped boss portion and a ramp portion integrally connected to the inner side of the "U"-shaped boss portion. The inner top of the "U"-shaped boss portion has a chamfer, and the openings of the "U"-shaped boss portion are distributed upwards, indicating the insertion orientation when the cylinder insert is plugged into the vehicle body and defining the insertion position. The inclined platform has a guide slope that gradually slopes from bottom to top toward the opening of the "U"-shaped boss, which facilitates the process of inserting the cylinder part into the vehicle body. The cylinder part is inserted and snapped into the corresponding snapping structure on the vehicle body by the snapping part 122.

[0022] This automotive cylinder head assembly uses a 12-pin connection structure. The terminal assembly includes twelve connection terminals 2 arranged in an array. Each connection terminal 2 passes through the connector sleeve 12, with its two ends located inside the first and second connector slots, respectively. The two ends of the connection terminal 2 are used to connect to the connectors on both sides. Figure 4 As shown, the middle part of the connecting terminal 2 has an "I"-shaped boss structure. The "I"-shaped boss structure is embedded in the plug tube part 12, so the connecting terminal 2 is prevented from falling off by the "I"-shaped boss structure, which can ensure effective current and signal transmission.

[0023] like Figure 1 and Figure 3 As shown, multiple guide strips 121 are provided on the upper outer circumferential surface of the plug-in cylinder 12. The guide strips 121 are distributed along the length of the plug-in cylinder 12. The guide strips 121 can play a role in preventing mistake and indicating the connection position, and can also guide the process of plugging the cylinder part of the car into the vehicle body.

[0024] The lower part of the plug-in sleeve 12 has two symmetrically arranged slots 1201, which are respectively connected to both sides of the second plug slot. The slots 1201 have a gradually upward sloping plug-in surface from the outside to the inside. The lower part of the plug-in sleeve 12 has a through-hole 1202, which communicates with the slot 1201. When the external plug structure is inserted into the second plug slot, it is electrically connected to the bottom end of the connecting terminal 2. The external plug structure has a snap-fit ​​structure that is adapted to the slot 1201. Under the guidance of the plug-in slope, it can extend into the slot 1201 and snap outward into the snap-fit ​​hole 1202, improving the reliability of the plug-in connection.

[0025] like Figure 2As shown, the mounting platform 11 has two symmetrical mounting holes, each with a metal bushing 3 to protect it and allow the cylinder head assembly to be installed at the target location on the vehicle body. The bottom of the mounting platform 11 has a positioning boss 111 located outside one of the bushings 3. This boss indicates the installation direction of the cylinder head assembly. The positioning boss 111 is located on the side opposite to the connection position. If the positioning boss 111 is turned towards the connection position on the vehicle body, it will obstruct the smooth connection of the cylinder head assembly, thus reminding the user to flip the cylinder head assembly for correct connection.

[0026] like Figure 3 As shown, an installation groove is provided on the lower outer circumferential surface of the insertion sleeve 12, and a sealing ring 4 is fitted into the installation groove. When installing the cylinder penetration component, the snap-fit ​​part 122 snaps onto the vehicle body, and the sealing ring 4 is compressed to ensure the sealing between the cylinder penetration component and the vehicle body.

[0027] In this embodiment, the latching part 122 on the base 1 provides effective positioning. The connecting terminal 2 is designed as an integrated unit. The "I"-shaped boss structure in the middle of the connecting terminal 2 is embedded in the plug cylinder part 12. The connecting terminal 2 is positioned to prevent detachment through the "I"-shaped boss structure, which can ensure effective electrical connection and prevent the inability to transmit current and signals, thus ensuring the effective operation of the cylinder connector.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
