Description

Technical Field

[0001] This invention relates to the field of connectors, and more particularly to a floating connector assembly. Background Technology

[0002] With the development of communication technology, various military and civilian microwave communication, mobile communication, and precision testing instruments are becoming increasingly miniaturized. When multiple connectors need to be installed on the same circuit board, the relative position of each connector needs to be very precise. To address the performance loss caused by connector gaps during high-frequency signal transmission and to reduce manufacturing costs, connectors need to have axial and radial floating capabilities. However, traditional threaded fixing structures are bulky, unsuitable for high-density installation, and require the application of thread-locking adhesive to prevent loosening, increasing the difficulty of assembly and disassembly. Claw fixing structures have low structural strength, and axial forces can easily cause the claws to deform, loosen, or fail. Fixing structures with irregular retaining rings have difficult parts processing and require specialized installation tools. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the performance loss caused by the gap between multiple sets of connectors in the prior art, and to provide a floating connector assembly.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A floating connector assembly includes a connector, a fixing structure, and a mounting panel. The mounting panel has a mounting hole, and the fixing structure is fixed in the mounting hole by a connector. An elastic element is provided between the connector and the fixing structure in the axial direction. One end of the connector is provided with the fixing structure, and there is a first gap between the connector and the fixing structure. The other end of the connector is provided with a step, and there is a second gap between the step and the mounting hole.

[0006] In this design, the connector is fixed within the mounting hole by a fixing structure, which in turn is installed into the mounting hole via a connector. In the axial direction, an elastic element is provided between the fixing structure and the connector, allowing the connector to tend to separate from the fixing structure and achieve axial floating. A step is provided at one end of the connector to limit its movement; a fixing structure is provided at the other end to limit its movement. By setting the size of the step, a gap is created between the step and the mounting hole, achieving radial floating while also making the connector easier to manufacture and install, thus increasing the finished product yield.

[0007] Preferably, the junction of the step and the connector is a guide angle.

[0008] In the scheme, the step at the junction with the connector is a guide angle, which can play a guiding role and prevent the connector from being damaged to some extent when being inserted, and also make the connector and the mounting hole on the same axis in a free state, facilitating processing.

[0009] Preferably, the outer surface of the fixing structure is provided with a positioning groove.

[0010] In the scheme, the surface of the fixing structure is provided with a positioning groove, which can prevent the fixing structure from rotating in the mounting hole, thereby playing a positioning role.

[0011] Preferably, the connecting piece is a pin, the mounting hole is provided with a pin hole, the positioning groove and the pin hole are communicated, and the pin is fixed in the mounting hole through the pin hole.

[0012] In the scheme, the positioning groove can facilitate the smooth insertion of the pin into the body of the fixing structure and realize the fixation between the fixing structure and the mounting panel; in addition, the pin connection has small part processing difficulty, greatly shortening the thickness requirement of the mounting panel.

[0013] Preferably, the elastic piece is a wave spring.

[0014] The positive progress effect of the present application is that:

[0015] The connector is fixed in the mounting hole through the fixing structure, and the fixing structure is installed into the mounting hole through the connecting piece; in the axial direction, the elastic piece is arranged between the fixing structure and the connector, so that the elastic force of the elastic piece makes the connector and the fixing structure have a separation trend and realize axial floating; in addition, the connector is provided with a step at one end, thereby limiting the one end of the connector; the other end of the connector is provided with the fixing structure, thereby limiting the other end of the connector. By setting the size of the step, the step and the mounting hole have a gap, which realizes radial floating, and also makes the connector easy to manufacture and install, improving the high qualified rate of finished products.

[0036] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0037] like Figures 1-6 As shown, a floating connector assembly includes a connector 1, a fixing structure 3, and a mounting panel. The connector 1 can be a socket electrical terminal, a pin electrical terminal, a socket RF connector, or a pin RF connector. The mounting panel has mounting holes 5. The fixing structure 3 is fixed within the mounting holes 5 by connectors 4. An elastic element 2 is provided between the connector 1 and the fixing structure 3 along the axial direction. A first gap 14 is provided between the fixing structure 3 and the connector 1. A second gap 12 is provided between the connector 1 and the mounting holes 5 along the radial direction.

[0038] Connector 1 is fixed in the mounting hole 5 by fixing structure 3, and fixing structure 3 is installed in the mounting hole 5 by connector 4. In the axial direction, elastic element 2 is provided between fixing structure 3 and connector 1, so that the elastic force of elastic element 2 makes connector 1 tend to separate from fixing structure 3 and realize axial floating. In addition, in addition to the gap between fixing structure 3 and connector 1 in the radial direction, there is also a gap between connector 1 and mounting hole 5 in the radial direction, so as to realize radial floating.

[0039] like Figures 1-3 As shown, connector 1 is an SMP structure RF connector 1. There are 3 mounting holes 5 on the mounting panel, and one connector 1 is fixed in each mounting hole 5. The elastic element 2 is in the form of a wave spring, which is 0.65mm in the free state and 0.15mm after compression, and can achieve an axial floating of 0.5mm.

[0040] One end of connector 1 is provided with a fixing structure 3, and a first gap 14 is provided between connector 1 and fixing structure 3. The other end of connector 1 is provided with a step, and a second gap 12 is provided between the step and mounting hole 5. Preferably, the size of the first gap 14 is set to 0.25mm, and the size of the second gap 12 is set to 0.2mm. The size of the second gap 12 is smaller than the size of the first gap 14, which can achieve a deviation of 0.25mm before docking and a radial float of 0.2mm after docking.

[0041] like Figure 1 and Figure 2 As shown, this embodiment includes a first step 51 and a second step 16. A guide angle 11 is provided at the junction of the first step 51 and the second step 16. The diameter of the first step 51 is smaller than that of the second step 16. A step is provided at the left end of the connector 1 to limit the left end of the connector 1; a fixing structure 3 is provided at the right end of the connector 1 to limit the right end of the connector 1.

[0042] Preferably, the junction of the step and connector 1 is a guide angle 11. Setting the junction of the step and connector 1 as a guide angle 11 can not only serve as a guide and prevent the connector 1 from being damaged during insertion to a certain extent, but also ensure that the connector 1 and the mounting hole 5 are on the same axis in the free state, which facilitates processing.

[0043] Preferably, the outer surface of the fixing structure 3 is provided with a positioning groove 31. In this embodiment, the body of the fixing structure 3 is a hollow cylinder, and the positioning groove 31 on the surface of the fixing structure 3 can prevent the fixing structure 3 from rotating in the mounting hole 5, thereby playing a positioning role.

[0044] Preferably, the connector 4 is a pin, and the mounting hole 5 has a pin hole 52. The positioning groove 31 communicates with the pin hole 52, and the pin passes through the pin hole 52 to fix the fixing structure 3 in the mounting hole 5. Figure 6 As shown, the fixing structure 3 has pin holes 52 at both ends and a positioning groove 31 on the fixing structure 3, which can facilitate the smooth insertion of pins into the body of the fixing structure 3 and realize the fixing between the fixing structure 3 and the mounting hole 5; in addition, the use of pin connection reduces the difficulty of parts processing and greatly shortens the thickness requirement of the mounting panel.

[0045] Preferably, the elastic element 2 is a wave spring. For example... Figure 4As shown, the use of wave springs can better adapt to tight axial and radial spaces to meet the precise operating conditions during connector mating.

[0046] In this embodiment, the left end step of the connector has two layers, namely a first step 51 and a second step 16, and there is a second step gap 13 between the step and the mounting hole 5. By setting the size of the step to create a gap between the step and the mounting hole 5, radial floating is achieved, while also making the connector 1 easier to manufacture and install, thus improving the finished product qualification rate.

[0047] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
