DETAILED DESCRIPTION
[0021] A preferred embodiment of the present application will now be described in detail with reference to the accompanying drawings.
[0022] The present application relates to a floating mechanism used to accurately align a plug connector and a socket connector during mating, so as to avoid structural damage, such as mating guide and / or conductive elements, caused by forced insertion due to inaccurate alignment. The plug connector and the socket connector can refer to those described in the patent application No. 202510908638.3.
[0023] As shown in FIGS. 1-12, the floating assembly 100 is floatingly retained between the upper base 31 and the lower base 32 of a device 300 (e.g., a cartridge). The floating assembly 100 includes a metal frame 10 and an elastic assembly 20. The metal frame 10 is provided with at least one connector receiving cavity 11 for tightly receiving a plug connector (e.g., a backplane), the rear end of which can be connected to a cable. The plug connector and the socket connector can be those in the patent application No. 202510908638.3. That is, the device 300 has a receiving cavity 33 for receiving the floating assembly 100 and allowing the cable to pass through. The upper base 31 and the lower base 32 jointly define the receiving cavity 33. The upper base and the lower base can be part of the housing of the device 300, or can be separate from the housing of the device 300. Two guide pins 12 extend forwardly from the front surface 143 of the metal frame 10, for insertion into two guide holes of a socket connector mounted on a mating device (e.g., a switch). The elastic assembly 20 is located at the rear of the metal frame 10 and is blocked by the rear inner wall 331 of the receiving cavity 33, as shown in FIG. 2. When the guide pins 12 are inserted into the guide holes, the elastic assembly 20 provides sufficient elastic force to keep the metal frame 10 in a forward position, as shown in FIGS. 3 and 4. Figure 4 When the plug connector starts to be inserted into the socket connector, the metal frame 10 is driven to move rearwardly together with the plug connector until the two connectors are mated with each other.
[0024] The elastic assembly 20 includes three coil springs 21 and three long rods 22 with nuts 221. As shown in Fig. 2, the front section of each coil spring 21 is received in the channel 13 provided in the metal frame 10, the long rod 22 is inserted into the rear section of the coil spring 21, and the nut 221 is pressed against the rear inner wall 331 of the receiving cavity 33. The front end of the coil spring 21 is positioned at the positioning pin 131 in the channel 13. Each upper base 31 and lower base 32 has a blocking portion 361, 362 behind the limiting post 34, and the elastic assembly 20 is pressed against the blocking portion 361, 362. The front surface of the blocking portion defines the rear inner wall 331 of the receiving cavity 33.
[0025] The metal frame 10 has a top surface 141, a bottom surface 142, and a rear surface 144. The metal frame 10 is provided with four guide posts 15 on the top surface 141 and the bottom surface 142, and has a through hole 16 between the top surface 141 and the bottom surface 142. The guide pin 12 is located at approximately the middle of the metal frame 10, and the through hole 16 is located behind the guide pin 12. Each upper base and lower base has a limiting post 34 and four guide recesses 35. The limiting post 34 extends downward / upward and protrudes into the through hole 16. The cooperation of the limiting post 34 and the through hole 16 limits the forward position and the rearward position of the floating assembly 100 in the docking direction X-X (Fig. 1).
[0026] As shown in Figs. 3-5, each guide recess 35 has a tapered inner wall surface 351 with a slope surface. Each guide recess 35 converges forward, and the through hole 16 converges rearward. From the top-down direction (as shown in Fig. 9), the through hole 16 is tapered, with a rear tip 161 at the rear end. From the top-down direction, the guide recess 35 is tapered, with a front tip 352 at the front end, as shown in Fig. 7. When the plug connector starts to be inserted into the socket connector, the interface of the two connectors provides further accurate alignment, and the floating assembly 100 will move along the tapered inner wall surface 351 under the push of the elastic assembly 20, starting to self-align. The metal frame 10 can move or float in the X, Y, Z axes or three axes, moving the metal frame 10 back to the center position. Therefore, the centering of the metal frame 10 will accurately mate the plug connector with the socket connector, thereby achieving the self-return function. In summary, the floating assembly and the guide recesses in the device together constitute a floating mechanism.
[0027] It is noted that conductive components will be provided within the connector housing of the plug connector, and for simplicity and clarity, these conductive elements are omitted from the figures. Likewise, conductive elements provided in the socket connector are also omitted from the figures where applicable.
[0028] In summary, the above is only the preferred embodiment of the present application, should not be limited by the scope of the present application, namely, the simple equivalent changes and modifications made in accordance with the claims and the contents of the present application, should still be within the scope of the present application.
