Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a 90° adapter connector assembly. Background Technology

[0002] Existing terminal connection structures are typically used for the conductivity and shielding functions of connectors. Most existing terminals are 180° structures, which cannot directly transmit signals and energy at approximately 90° angles. However, in practical applications, terminals are required to transmit signals and energy at approximately 90° angles. This type of connector primarily accommodates the mating of devices in specific spaces and at specific angles. Changes in angle will also lead to changes in the connector's internal structure, requiring consideration of the mounting connection with the device housing, the mounting connection with the shielding shell, and the placement of the outer conductor. This cannot be achieved by simply bending existing connector structures; ease of assembly and production costs must be carefully considered. Utility Model Content

The connection method between the mating part and the mating groove of the third electrical connection component of this utility model allows the floating seat to float flexibly relative to the base, effectively compensating for connector mating position deviations caused by vehicle assembly errors, vibrations, and other factors. The buffer part of the third electrical connection terminal has a U-shaped cross-section, which provides excellent elasticity and cushioning performance. During vehicle operation, vibrations and impacts are inevitable. The U-shaped buffer part effectively absorbs these external forces, reducing the impact on the electrical connection part and the fixing part, preventing the pins from breaking or loosening due to vibration, and greatly extending the service life of the connector. At the same time, the buffer part can also compensate for minor positional changes between the pins and the electrical connection part to a certain extent, ensuring that they always maintain a good conductive connection.

[0045] Furthermore, the first contact portion 441 is arc-shaped and protrudes towards the outer periphery of the floating connector 44. The arc-shaped structure can enhance the contact area with the external conductive structure, improve the conductivity reliability, and at the same time have a certain elasticity to adapt to slight displacement.

[0046] The floating connector 44 has multiple slots 445 at one end near the second contact portion 442, each slot 445 extending to the second contact portion 442 to divide the second contact portion 442 into multiple second contact units. The multiple contact units achieve independent elastic contact, which can ensure that the second contact portion 442 can effectively conduct electricity. The fixed platform 415 is provided with a limiting groove 4154 for accommodating the contact units, which limits the contact units and prevents excessive deformation.

[0047] The cross-section of the second contact portion 442 is V-shaped. The V-shaped structure has good elastic recovery ability, ensuring close contact with the inner side of the floating connection portion 431. One end is connected to the floating connector 44, and the other end is connected to the concave slope 4421. The concave slope 4421 and the second contact portion 442 form a contact point for precise contact with the fixing member 43, thereby improving the conductivity stability.

[0048] like Figure 8 and Figure 9As shown, in this embodiment, the power receiving part 454 is provided with tight-fitting buckles 4541 on both sides. The tight-fitting buckles 4541 are used to tightly fit the power receiving part 454 in the mating cavity 422 to prevent the power receiving part 454 from shaking in the mating cavity 422 and improve the stability of the power connection. One end of the power receiving part 454 is provided with an elastic clamping part 4542. The elastic clamping parts 4542 are arranged in a ring array with three spaced apart. The ring array distribution ensures all-round contact with the second connecting pin 312. The end of the elastic clamping part 4542 is provided with an inlet ramp 4543 to facilitate the insertion of the second connecting pin 312, reduce insertion and extraction resistance, and protect the terminal structure.

[0049] During assembly, the first electrical terminal is riveted into the first insulating kit to form the first electrical assembly, and the second electrical terminal is riveted into the second insulating kit to form the second electrical assembly. Next, rivet the second electrical connection component into the zinc alloy sleeve, and then rivet the first electrical connection component into the zinc alloy sleeve and plug it into the second electrical connection component. Finally, apply waterproof adhesive to the front of the first electrical connection component, insert the third electrical connection component, and complete the connector assembly.

[0050] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
