[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0040] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0041] The blind mating guide flange connector fixing device in this application is mainly used for blind mating guidance of connectors such as J30J. By setting necessary mating structures and connecting the separate mating structures to the plug and socket respectively, blind mating of the connector plug and socket can be achieved.
[0042] By transforming the blind mating of connector plugs and sockets into a shaft hole mating based on a separate mating structure, the limitations of the installation structure can be overcome, thereby ensuring the reliability and convenience of blind mating operations.
[0043] See Figures 1-4The blind insertion guide flange connector fixing device of this utility model is mainly used for blind insertion guidance of plug connector 3 and socket connector 4. The main structure of the blind insertion guide flange connector fixing device includes a guide positioning locking member 1 and a guide fixing locking member 2, which are separately arranged and cooperate with each other through shaft holes.
[0044] By inserting the guide positioning locking member 1 into the connector mounting hole 5 of the plug connector 3 or the socket connector 4, and correspondingly inserting the guide fixing locking member 2 into the connector mounting hole 5 of the socket connector 4 or the plug connector 3, blind mating connection between the plug connector 3 and the socket connector 4 can be achieved during the mutual shaft hole mating process.
[0045] The guide docking part, which is composed of the positioning pin hole 11 provided on the guide positioning locking part 1 and the docking pin 21 provided on the guide fixing locking part 2, forms a split mating structure. The plug connector 3 and the socket connector 4 are blindly mated by the shaft hole of the docking pin 21 and the positioning pin hole 11 through the shaft hole insertion cooperation.
[0046] The positioning threaded post 12 included in the guide positioning locking member 1 can protrude from the circuit board 10 or the fixing plate 9. By screwing the nut 6 onto the positioning threaded post 12 and by inserting the guide positioning locking member 1 into the connector, the separate structure of the guide positioning locking member 1 and the connector can be fixed onto the circuit board 10 or the fixing plate 9.
[0047] The guide fixing locking member 2 includes a fixing threaded post 22 that can protrude from the circuit board 10 or the fixing plate 9. By screwing the nut 6 onto the fixing threaded post 22 and by inserting the guide fixing locking member 2 into the connector, the separate structure of the guide fixing locking member 2 and the connector can be fixed onto the circuit board 10 or the fixing plate 9.
[0048] Furthermore, under the premise that the plug and socket of the connector are reliably blind-molded, the flange connector is fixed, ensuring that the overall structure formed by the flange connector and the fixing device is reliably and stably installed.
[0049] The guide positioning locking component 1 and the guide fixing locking component 2 in this utility model can be fixed on the fixing plate 9 or the circuit board 10 respectively. The connection relationship between the two separate mating structures and the plug or socket is also relative. For example, when the guide positioning locking component 1 is installed on the plug connector 3 on the fixing plate 9, the guide fixing locking component 2 is installed on the socket connector 4 on the circuit board 10.
[0050] It should be noted that the guide positioning locking member 1 and the guide fixing locking member 2 are respectively connected to the connector mounting hole 5 of the plug connector 3 or the socket connector 4. At the same time, the positioning threaded post 12 and the fixing threaded post 22 are respectively fixed in the mounting hole on the fixing plate 9 or the circuit board 10. In order to facilitate the explanation of the installation parts, the connector mounting hole 5 is used to refer to the connector mounting hole 5 of the plug connector 3 or the socket connector 4, and the board mounting hole 7 is used to refer to the mounting hole on the fixing plate 9 or the circuit board 10.
[0051] Regarding the composition of the split-type mating structure, this application will illustrate with an example in which the guide positioning locking member 1 is connected to the plug connector 3 on the fixing plate 9, and the guide fixing locking member 2 is fixed to the socket connector 4 on the circuit board 10.
[0052] The guide positioning locking component 1 includes a positioning pin 13 that inserts into the connector mounting hole 5, enabling the guide positioning locking component 1 to establish a connection with the flange connector via the positioning pin 13. The positioning pin 13 is mainly used to guide the connector mounting hole 5 of the plug connector 3 and the mounting hole on the fixing plate 9. It is designed with a small clearance, precise fit, and very small axial deviation, which can ensure the accuracy of guide positioning.
[0053] A positioning flange limit seat 14 is connected to the other side of the positioning pin 13 relative to the positioning threaded post 12. The outer diameter of the positioning flange limit seat 14 is larger than the outer diameter of the positioning pin 13, and a guide chamfer 15 is provided at the joint between the positioning flange limit seat 14 and the positioning pin 13.
[0054] The guide chamfer 15 is specifically a 90° chamfer, which has a centripetal function. During the mating process, the guide chamfer 15 centripetally fine-tunes the flange connector to ensure that the axis is aligned.
[0055] The positioning threaded post 12 is connected to the side of the positioning pin 13 and is mainly used to fix the plug connector 3 and the fixing plate 9. It is then tightened with an M2 nut 6. However, after tightening, the connector can wobble due to the small gap formed by the guide chamfer 15.
[0056] The positioning limit seat is mainly used to fix the plug connector 3 and the fixing plate 9, and to limit the plug connector 3 from producing excessive fine adjustment gap.
[0057] The positioning pin hole 11 mainly cooperates with the longer docking pin shaft 21 of the guide positioning and fixing locking component. During the connector mating process, the docking pin shaft 21 and the positioning pin hole 11 of the guide positioning and fixing locking component 2 are the first to cooperate. The pin hole cooperation achieves pre-positioning. Then the plug connector 3 is adjusted in preparation for the subsequent mating of the connector plug and the socket housing.
[0058] By setting the guide chamfer 15, the plug connector 3 can be finely adjusted in axis after the positioning pin hole 11 and the mating pin shaft 21 are pre-positioned and engaged, ensuring accurate mating during blind mating.
[0059] Both the positioning pin 13 and the positioning flange limit seat 14 are hollow structures. The positioning pin hole 11 includes a blind hole channel provided in the cavity inside the positioning pin 13 and the positioning flange limit seat 14. The blind hole channel extends linearly along the axial direction of the positioning pin 13 and the positioning flange limit seat 14 to ensure accurate positioning during the pre-positioning process.
[0060] Furthermore, the positioning threaded post 12, positioning pin 13, guide chamfer 15, positioning flange limit seat 14, and positioning pin hole 11 are coaxially arranged. Combined with the positioning pin 13 being inserted into the mounting hole of the plug connector 3, the entire guide positioning locking component 1 can be coaxially installed in the mounting hole of the plug connector 3 to ensure the reliability of blind mating.
[0061] The fixing plate 9 or the circuit board 10 is provided with a board mounting hole 7, and the positioning pin 13 passes through both the connector mounting hole 5 and the board mounting hole 7. Specifically, the positioning pin 13 passes through both the mounting hole of the plug connector 3 and the mounting hole on the fixing plate 9, thereby ensuring the locking connection of the plug connector 3 on the fixing plate 9.
[0062] To elaborate further, the guide fixing locking member 2 includes a fixing pin 23 inserted into the connector mounting hole 5, a fixing threaded post 22 connected to the side of the fixing pin 23, a fixing flange limiting seat 24 connected to the other side of the fixing pin 23 relative to the fixing threaded post 22, and the root of the mating pin 21 connected to the fixing flange limiting seat 24.
[0063] The outer diameter of the fixed threaded post 22 is smaller than the outer diameter of the fixed pin 23. The fixed flange limiting seat 24 includes a polygonal prism structure and its outer diameter is larger than the outer diameter of the fixed pin 23. The outer diameter of the mating pin 21 is smaller than the outer diameter of the fixed threaded post 22.
[0064] Compared to the installation of the guide positioning locking component 1 on the plug connector 3 and the fixing plate 9, the longer mating pin 21 on the guide fixing locking component 2 is mainly used to tightly cooperate with the positioning pin hole 11 of the guide positioning locking component 1. The fixing flange limit seat 24 is mainly used to fix the socket connector 4, and the fixing pin 23 mainly cooperates with the mounting hole of the socket connector 4 to ensure that the mounting hole of the guide fixing locking component 2 and the socket connector 4 are on the same axis. The fixing threaded post 22 is mainly used to fix the socket connector 4 and the circuit board 10, and is fastened by the M2 nut 6.
[0065] The mating pin 21, the fixed flange limit seat 24, the fixed pin 23, and the fixed threaded post 22 are coaxially arranged. By inserting the fixed pin 23 into the mounting hole of the socket connector 4, the entire guide fixing locking component 2 can be coaxially installed in the mounting hole of the socket connector 4, so as to ensure the reliability of blind mating.
[0066] Based on the above-mentioned structural composition and installation relationship of the guide positioning locking component 1 and the guide fixing locking component 2, the outer side of the fixed threaded post 22 is fitted with a limiting sleeve 8. The limiting sleeve 8 provides limiting support between the connector mounting hole 5 and the board mounting hole 7, which can play a good limiting role. Furthermore, through the action of the pad post, it prevents the connector solder pins from being stressed during mating.
[0067] During connection and installation, the positioning threaded post 12 and the fixing threaded post 22 protrude at least a certain length from the fixing plate 9 or the circuit board 10, and are locked by screwing in the nut 6 to ensure reliable fixing.
[0068] The above description process is carried out with the guide positioning locking component 1 installed on the fixed plate 9 and the plug connector 3, and the guide fixing locking component 2 installed on the circuit board 10 and the socket connector 4. The fixed plate 9 and the circuit board 10 are interchangeable. The connector axis position is adjusted by the locking component of the split mating structure to ensure that the connector itself with its own shell can be smoothly mated.
[0069] The blind-mating guide flange connector fixing device in this utility model only has a good guiding function, and the connector mating limit is completed by the connector itself.
[0070] The guide fixing locking component 2 and the flange socket connector 4 are fixed together on the circuit board 10. A nut 6 is provided on the back of the circuit board 10. The guide fixing locking component 2 has a fixing pin 23 that fits precisely with the connector mounting hole 5 to ensure accurate axial positioning.
[0071] The guide positioning locking component 1 and the flange plug connector 3 are fixed together on the fixing plate 9. The fixing plate 9 has a nut 6 on the back. The guide fixing locking component 2 has a positioning pin 13 that can achieve a precise shaft hole fit with the connector mounting hole 5. After assembly, a certain fine adjustment gap is left to ensure that the shaft center position can be finely adjusted during the insertion process.
[0072] During the blind mating process of the connector, the mating pin 21 of the guide fixing locking part 2 and the positioning pin hole 11 of the guide positioning locking part 1 first make a precise shaft hole fit. At this time, based on the self-contained guide chamfer 15 of the guide positioning locking part 1, the position of the plug connector 3 is finely adjusted to ensure that the mounting hole of the plug connector 3 is on the same axis as the guide positioning locking part 1, the guide fixing locking part 2 and the mounting hole of the flange socket connector 4.
[0073] Fine-tune the position of plug connector 3 to ensure that the housing of socket connector 4 and the housing of plug connector 3 are properly mated. Then, readjust the position of flange plug connector 3 to ensure that the pins and sockets are properly mated and that the limit sleeve 8 provided with the connector is used for limiting.
[0074] The blind-fit guide flange connector fixing device in this utility model enables flange connectors such as J30J to be accurately and correctly blind-fitted and to be used normally under vibration, impact and other environments.
[0075] It is also particularly suitable for connectors such as J30J that have built-in flange mounting holes, and has high applicability in blind mating guidance and fixing of connector sockets and plugs.
[0076] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0077] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
