Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of signal connection devices, and specifically to a floating connector. Background Technology
[0002] Signal connection devices generally include male and female connectors. Signal transmission is achieved by connecting the male and female connectors. Existing signal connection devices are widely used in various fields, such as computer communication and vehicle signal communication.
[0003] To improve insertion accuracy and achieve reset, existing signal connection devices typically incorporate elastic elements inside the plug. For example, see patent application CN205752793U (publication date November 30, 2016) discloses an RF coaxial connection device, which discloses that "by providing a first floating spring 310 within the first adjustment cavity 302, the position of the male connector 400 can be adjusted more flexibly and conveniently, and after disengaging from the female connector 600, the male connector 400 can reset under the action of the first floating spring 310." Also see patent application CN215896857U (publication date February 22, 2022) discloses a flexible charging device, which discloses that "various movement modes are provided for the charging male connector 21 to meet various needs." The dynamic centering adjustment requirement effectively solves the problem of poor centering of existing charging mechanisms; see also the lightweight interconnected integrated test device disclosed in patent application CN206864818U, published on January 9, 2018, which discloses that "the body of the BMA connector 5 is sleeved with a spring 3, one end of the spring 3 acts on the body of the BMA connector, and the other end, i.e. the end, acts on the cavity wall around the mounting channel; the head part of the BMA connector 5 is partially exposed outside the mounting channel. When the compressed spring causes the BMA connector to float axially, the head part of the BMA connector in the mounting channel can play a radial guiding role on the BMA connector, thereby improving the insertion alignment accuracy of the connector."
[0004] When using existing through-board connectors, such as when installing the connector onto a circuit board, precision deviations can easily occur during the assembly process, leading to misalignment of the connector and making it difficult to fit accurately.
[0005] Meanwhile, existing connectors can generate compressive stress when misalignment occurs. The long-term accumulation of this stress may affect the stability of the connector and circuit board, and even lead to malfunctions.
[0006] In addition, in some complex working environments, such as aerospace and automotive electronics, equipment may be affected by external factors such as vibration and thermal expansion, resulting in vibration or deformation, and fixed-structure connectors are not suitable.
[0007] Therefore, there is an urgent need to provide a solution to address the defects and shortcomings of the existing technologies. Summary of the Invention
[0008] In order to overcome the defects and shortcomings of the existing technology, this utility model provides a floating connector.

One end of the first elastic element is fixedly connected to the first elastic limiting part, and the other end is fixedly connected to the inner wall of the outer shell.
[0017] As a further preferred embodiment of the present invention, there is a radial gap between the outer edge of the inner shell and the inner wall of the outer shell.
[0018] As a further preferred embodiment of the present invention, the outer edge of the outer shell is provided with an outer edge fixing part protruding outward.

[0034] [First Embodiment]
[0035] like Figure 1-6 The image shown is a floating connector provided in the first embodiment of this utility model, as follows: Figure 1-3 As shown, it includes a plug 1, which is fixed inside an insulator 2, which is disposed inside a housing. In this embodiment, the plug 1 is fixed inside the insulator 2 by crimping, and the insulator 2 is also fixed inside the inner housing 3 by crimping.
[0036] The improvement of this embodiment compared to the prior art is as follows: the housing includes an inner shell 3 and an outer shell 4. The insulator 2 is fixed inside the inner shell 3, and the inner shell 3 is movably disposed inside the outer shell 4 in a floating manner. A first elastic element 6 is provided between the inner shell 3 and the outer shell 4, thereby realizing the floating connection of the inner shell relative to the outer shell. The first elastic element 6 provides elastic restoring force after floating deformation to help the inner shell 3 return to its initial position, thereby absorbing the precision deviation generated during the assembly process, facilitating the accurate insertion of the connector, and thus ensuring a stable and effective connection. At the same time, the floating connection of the inner shell relative to the outer shell can eliminate the stress caused by misalignment, thereby protecting the connector, improving the insertion reliability of the connector, and extending its service life. In addition, the floating connection of the inner shell relative to the outer shell can more flexibly adapt to changes in the surrounding environment and maintain a stable insertion effect.
[0037] like Figure 4 As shown, in this embodiment, in order to limit the floating movement of the inner shell 3 relative to the outer shell 4, a retaining ring 5 is snapped onto the outer rear end of the inner shell 3. The retaining ring 5 moves synchronously with the inner shell 3 and is axially limited and matched with the outer shell 4, thereby limiting the inner shell 3 during the process of the inner shell 3 returning to its initial position after floating deformation.
[0038] like Figure 4 As shown, the inner wall of the inner shell 3 extends out and is provided with an insulator limiting part 31 that cooperates with the limiting of the insulator 2, thereby further improving the fixed stability of the insulator 2 inside the inner shell 3.
[0039] A second elastic element 7 is fixed inside the front end of the inner shell 3. By fixing the second elastic element inside the front end of the inner shell, the second elastic element can effectively absorb the internal stress generated during the insertion process, thereby effectively protecting the connector and further extending its service life. Correspondingly, a second elastic limiting part 32 is provided on the inner wall of the front end of the inner shell 3 to cooperate with the second elastic element 7. By providing the second elastic limiting part 32, the second elastic element 7 can be stably located inside the front end of the inner shell 3. Preferably, the second elastic element 7 in this embodiment is an elastic spring.
[0040] The outer edge of the rear end of the inner shell 3 extends out and is provided with a first elastic limiting part 33 that cooperates with the first elastic member 6. One end of the first elastic member 6 is fixedly connected to the first elastic limiting part 33, and the other end is fixedly connected to the inner wall of the outer shell 4. Thus, the first elastic member 6 can be stably sleeved on the outer periphery of the inner shell 3 and located between the inner shell 3 and the outer shell 4 through the first elastic limiting part 33. Preferably, the first elastic member 6 in this embodiment is a spring.
[0041] Those skilled in the art should understand that, to facilitate the floating movement of the inner shell 3 relative to the outer shell 4 within the outer shell 4, a radial gap exists between the outer edge of the inner shell 3 and the inner wall of the outer shell 4. This gap, to a certain extent, also allows for relative radial movement of the inner shell 3 relative to the outer shell 4. Furthermore, an outer edge fixing part 41 protrudes from the outer edge of the outer shell, and the connector is fixedly connected to one side of the plate 8 through fixing holes provided on the outer edge fixing part 41. Figure 6 As shown, by adopting a floating connection between the inner shell and the outer shell, the inner shell 3 can achieve a floating motion with a stroke of L in the axial direction relative to the outer shell 4 inside the outer shell 4.
[0042] The specific assembly process of the connector provided in this embodiment includes:
[0043] S1: Press the insulator 2 into the inner shell 3;
[0044] S2: Press the plug 1 into the insulator 2;
[0045] S3: Insert the second elastic element 7 into the front end of the inner shell 3;
[0046] S4: Fit the first spring 6 onto the outer periphery of the inner shell 3;
[0047] S5: Assemble the inner shell 3 and the outer shell 4 together, and while compressing the first elastic element 6, snap the retaining ring 5 into the retaining groove of the inner shell 3.
[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
