Description

Technical Field

[0001] This utility model relates to the field of automotive connectors, and in particular to a small automotive LED light connector. Background Technology

[0002] With the development of society and the economy and the improvement of people's living standards, new energy vehicles have become an emerging means of transportation and are loved by many people. Their market share is increasing. New energy vehicles have many advantages, including saving fuel, reducing emissions, effectively protecting the environment, low noise, and low operating costs. As automobiles develop towards multi-functionality, comfort, aesthetics, and energy sustainability, automotive connectors are also developing rapidly and facing more challenges.

[0003] The function of automotive connectors is very simple: to bridge the gaps in a circuit or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function.

[0004] Currently, LED automotive connectors used in small cars typically consist of an insulating body and two terminals. The front end of the insulating body has a recessed cavity, and the two terminals are inserted into the lower end of the insulating body to secure them. While this type of connector has a simple structure and can achieve basic circuit connection functions, during the manufacturing process, after the connector is soldered onto the PCB board, the connection between the terminals and the insulating body is not robust enough, resulting in poor terminal retention. During subsequent assembly, the terminals easily loosen, leading to a high defect rate and causing production inconvenience. In use, when the external connector is mated to the automotive connector, the terminals easily slip or fall off, interrupting the circuit connection. Furthermore, when the external connector is removed, the insulating body and terminals of the automotive connector easily separate, causing damage to the connector. This results in poor product quality, a poor user experience, and fails to meet current requirements. Therefore, it is necessary to research a new technical solution to improve current automotive connectors. Utility Model Content

[0005] In view of the above, this utility model addresses the deficiencies of the existing technology and its main purpose is to provide a small automotive LED light connector. This connector effectively solves the problems of existing LED light automotive connectors, such as: after the automotive connector is soldered onto the PCB board during production, the connection structure between the terminals and the insulating body is not stable enough, resulting in poor terminal retention. This leads to easy loosening of the terminals during subsequent assembly, resulting in a high defect rate and inconvenience to production. Furthermore, during use, when the external connector is plugged into the automotive connector, the terminals are prone to slippage or detachment, causing circuit interruption. When the external connector is pulled out, the insulating body and terminals of the automotive connector easily separate, causing damage to the automotive connector and resulting in poor product quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A small automotive LED light connector includes an insulating body, terminals, and a suction cap. The insulating body has an upward-facing insertion cavity. There are two terminals, which are embedded in the lower end of the insulating body. Each terminal includes an integrally formed contact portion, a fixing portion, and a soldering portion. The contact portion extends upward into the insertion cavity and is exposed on the inner wall of the insertion cavity. Protrusions are provided on the left and right sides of the contact portion and are embedded in the insulating body. The fixing portion is embedded in the insulating body, and the soldering portion extends outward from the insulating body. The suction cap is detachably disposed on the upper end of the insulating body and covers the upper opening of the insertion cavity.

[0008] As a preferred embodiment, the protrusion has a serrated structure, which effectively enhances the holding force of the terminal and strengthens the stability of the connection structure between the terminal and the insulating body.

[0009] As a preferred embodiment, two protrusions are symmetrically arranged on the left and right sides of the contact portion, and all four protrusions are embedded in the insulating body, further enhancing the stability of the connection structure between the terminal and the insulating body.

[0010] As a preferred embodiment, the welded part has a C-shaped structure, which helps to enhance the stability of the connection structure between the terminal and the insulating body, making the structure more reliable.

[0011] As a preferred embodiment, the longitudinal section of the terminal is L-shaped.

[0012] As a preferred embodiment, the insertion cavity is symmetrically provided with fixing grooves on the left and right sides, and the two terminals are symmetrically arranged at the lower end of the insulating body. The upper ends of the contact parts of the two terminals are respectively arranged in the corresponding fixing grooves for fixation, which helps to enhance the fixing ability of the terminals and make the connection structure between the terminals and the insulating body more stable.

[0013] As a preferred embodiment, the bottom left and right sides of the insulating body are symmetrically provided with limiting grooves, and the two terminals are symmetrically arranged at the lower end of the insulating body. The welding parts of the two terminals are respectively arranged in the corresponding limiting grooves, which helps to enhance the fixing ability of the terminals and make the connection structure between the terminals and the insulating body more stable.

[0014] As a preferred embodiment, the upper end of the insertion cavity is symmetrically provided with positioning grooves on both the front and rear sides. The suction cover includes a main body and two positioning buckles extending downward from the main body. The two positioning buckles are symmetrically arranged on the main body and are respectively positioned in the corresponding positioning grooves. The upper and lower surfaces of the main body form two through holes, which are respectively located on the upper outer side of the corresponding positioning buckles. During the production process, external parts can be inserted through the two through holes and pressed inward to disengage the two positioning buckles from the corresponding positioning grooves, thereby allowing the suction cover to be removed from the insulating body. The operation is simple and brings convenience to the production process.

[0015] As a preferred embodiment, the upper end of the insulating body is provided with a positioning part, and the suction cover includes two positioning blocks. The two positioning blocks extend downward from the main body and are arranged symmetrically on the left and right. The two positioning blocks are disposed between two positioning buckles, and the two positioning blocks cooperate with the positioning part for positioning.

[0016] As a preferred embodiment, the insulating body has a cylindrical structure.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0018] By embedding two terminals into the lower end of the insulating body, each terminal includes an integrally formed contact portion, a fixing portion, and a soldering portion.

During use, when the external connector is mated with the automotive connector, the terminals are not easy to slip or fall off, ensuring normal circuit connection and conduction. When the external connector is pulled out, the insulating body and terminals of the automotive connector will not separate, preventing damage to the automotive connector, improving product quality, enhancing user experience, and meeting current needs.
