[0019] As Figures 1-4 shown, the utility model discloses a kind of cylinder penetrating connection pieces of automobile, including base 1 and terminal assembly.
[0020] The base 1 top has the first slot 101, bottom has the second slot 102, and the first slot 101 and the second slot 102 are communicated by two installation channels.
[0021] The automobile cylinder penetrating connection piece is 2pin connection structure, and the terminal assembly includes two connection terminals 2 respectively arranged at the two installation channels of the base 1, the installation channel is blocked by the connection terminal 2, and the two ends of the connection terminal 2 are respectively located in the first slot 101 and the second slot 102, and are respectively used for electrical connection device on both sides. Figure 4As shown, the middle part of the connecting terminal 2 has an "I"-shaped boss structure. The "I"-shaped boss structure is embedded into the inner side of the mounting channel to improve the anti-detachment effect. The base 1 has a partition part 11 that separates the two connecting terminals 2 on the same side. Specifically, the partition part 11 separates the protruding parts of the two connecting terminals 2 inside the second slot 102 to prevent interference between the two connecting terminals 2, and guides the connector inserted into the second slot 102 so that the connector can be accurately aligned with the two connecting terminals 2 for insertion.
[0022] like Figure 1 and Figure 2 As shown, the base 1 includes an integrally formed main body and a connector. The connector extends through the main body, and the thickness of the main body is less than the length of the connector. Both ends of the connector extend outwards from the sides of the main body in the thickness direction. The lower structure of the connector is a polygonal cylindrical structure with a step at the bottom and a chamfer on the inner edge of the bottom, which serves to guide, prevent misplacement, and limit positioning during insertion. The first slot 101 and the second slot 102 are located on both sides of the connector, facing opposite directions.
[0023] like Figure 1 As shown, the main body has multiple weight-reducing grooves 103 along its outer circumferential surface, reducing the weight of the entire cylinder-through connector and lowering material costs. The insertion part has multiple inner grooves 104 arranged in a circumferential pattern on its outer periphery, further reducing material costs. The design of the weight-reducing grooves 103 and inner grooves 104 also increases the contact area with the outside air, dissipating heat generated by the connecting terminal 2 during operation and extending the service life of this cylinder-through connector.
[0024] The main body has mounting holes, and a fixing sleeve 3 is provided at the mounting holes. The fixing sleeve 3 is a metal bushing that protects the mounting holes and allows the cylinder connector to be installed at the target position on the vehicle body without damaging the base 1. The upper outer peripheral surface of the insertion part has a locking platform 12. The locking platform 12 has a "T" shaped structure and a guide slope, which allows it to be snapped into the target position on the vehicle body. The guide slope guides the connection process.
[0025] like Figure 1 As shown, the lower outer periphery of the insertion part has an annular groove, and a sealing ring 4 is fitted into the annular groove. When this cylinder connector is installed on the vehicle body, the sealing ring 4 will be squeezed by the vehicle body, and the sealing ring 4 will play a sealing role between the base 1 and the vehicle body to ensure airtightness.
[0026] In this embodiment, the integrated design of the connecting terminal 2 ensures electrical connection. The "I"-shaped boss structure can be embedded into the mounting channel of the base 1, improving the connection reliability of the connecting terminal 2 and effectively enhancing the anti-detachment effect. This allows for effective transmission of current and signals, preventing failure of the cylinder connection component. The partition 11 of the base 1 can separate one end of the two connecting terminals 2, preventing interference between the two connecting terminals 2.
[0027] 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.
