DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0030] An embodiment of a rectangular blind-mate connector using a connection transmission structure according to the present application is shown in FIG. 1. The connector includes a socket part, a plug part, a socket floating structure, an intermediate part 5, and a double jack structure 8. The socket part is disposed on the socket floating structure, and the socket part and the plug part are inserted into each other through the intermediate part 5 and the double jack structure 8. The part of the socket part and the plug part close to the insertion end is defined as the front end, the insertion direction is the longitudinal direction, and the direction perpendicular to the insertion direction is the transverse direction. Figures 3 to 7b

[0031] ​The socket assembly includes a socket housing 1, a socket insulator 3, socket pins 6, and a socket tail housing 11. The plug assembly includes a plug housing 2, a plug insulator 4, a plug pin 7, and a plug tail housing 12. The socket insulator 3 is housed within the socket housing 1, and the plug insulator 4 is housed within the plug housing 2. The front end of the socket housing 1 has a cavity for the plug assembly to insert into. The socket insulator 3 and plug insulator 4 are fixed into their respective socket housings 1 and plug housing 2 via a snap-fit ​​structure. The plug insulator 3 and socket insulator 4 have symmetrical and identical structures, allowing for interchangeability. Each has multiple corresponding stepped holes. The socket pins 6 and plug pins 7 have identical structures and are respectively positioned within the corresponding holes of the socket insulator 3 and plug insulator 4. The socket pins 6 and plug pins 7 are secured within the corresponding holes via a snap-fit ​​structure, with their heads extending out of the holes. After the socket pin 6 and plug pin 7 are inserted into the socket hole from the tail of the corresponding socket housing 1 and plug housing 2, the socket tail housing 11 is installed at the tail of the socket housing 1, and the plug tail housing 12 is installed at the tail of the plug housing 2.

[0032] Both the socket insulator 3 and the plug insulator 4 have intermediate components 5 at their mating ends. After the plug component and the socket component are mated together, the intermediate components 5 on the socket insulator 3 and the intermediate components 5 on the plug insulator 4 are aligned. The intermediate components on the socket insulator 3 and the intermediate components on the plug insulator 4 have the same structure and the same installation structure. Taking the intermediate component 5 on the socket insulator 3 as an example, the intermediate component 5 on the socket insulator 3 is a plate-shaped body with insertion protrusions 501 corresponding to the socket holes. The protrusions 501 extend to the front and rear sides of the intermediate component 5. One side of the intermediate component 5 is attached to the front end face of the socket insulator 3, and the protrusion 501 on this side is nested in the corresponding socket hole. The protrusion 501 on the other side of the intermediate component 5 extends to the front end and has a through hole. The head of the socket pin 6 is located in the through hole of the protrusion 501.

[0033] The intermediate component 5 is fixed to the corresponding socket insulator 3 and plug insulator 4 by screws. Before the plug component and socket component are inserted, the double-ended socket structure 8 is inserted into the intermediate component 5 of the socket insulator 3 or plug insulator 4. The double-ended socket structure 8 corresponds one-to-one with the pins on the socket insulator 3 or plug insulator 4. In this embodiment, before insertion, the double-ended socket structure 8 is inserted into the intermediate component 5 of the plug insulator 4, specifically by inserting the double-ended socket structure 8 into the through hole of the protrusion 501 on the intermediate component 5. The double-ended socket structure 8 is a tubular body, with a socket at each end. Multiple slots are provided on the wall of the socket, so that the ends of the double-ended socket structure 8 form multiple cantilever structures, which facilitates the insertion of the socket pin 6 and plug pin 7 into the double-ended socket structure 8. At the same time as the double-ended socket structure 8 is inserted into the through hole of the protrusion 501, the plug pin 7 is inserted into one end of the double-ended plug structure 8. After the plug component and the socket component are inserted, the socket pin 6 is inserted into the other end of the double-ended socket structure. The middle component on the socket insulator 3 and the middle component on the plug insulator 4 are connected to each other and their protrusions are connected. The double-ended socket structure 8 is located in the through holes of the two protrusions 501 to prevent the cantilever structure on the double-ended socket structure 8 from deforming. The double-ended socket structure 8 wraps around the socket pin 6 and the plug pin 7, so that the socket pin 6 and the plug pin 7 are firmly inserted into the double-ended socket structure 8.

[0034] Mounting plates 101 are provided on both sides of the rear of the socket housing 1. The extended plane of the mounting plate 101 is perpendicular to the insertion direction of the socket component and the plug component. The mounting plate 101 is provided with multiple floating through holes 102. Floating protrusions 103 are provided at the ends of the mounting plate 102.

[0035] The floating structure of the socket includes a floating block 9 and a threaded guide pin 10. In this embodiment, the threaded guide pin 10 is an M3 threaded guide pin 10. The threaded guide pin 10 corresponds one-to-one with the floating through hole 102. From head to tail, the threaded guide pin 10 consists of a light shaft 1001, a floating shaft 1002, a threaded shaft 1003, and a nut 1004. The diameter of the floating shaft 1002 is smaller than the diameter of the light shaft 1001 and smaller than the outer diameter of the threaded shaft 1003. Furthermore, the diameter of the floating shaft 1002 is 1.4~2.0mm smaller than the diameter of the floating through hole 102, allowing the floating shaft 1002 to float within the floating through hole 102 after insertion. A floating groove 901 is provided on one side of the floating block 9 for inserting the mounting plate 101. The floating groove 901 penetrates both side walls of the floating block 9, facilitating the insertion of the mounting plate 101 of the socket component into the floating groove 901. The bottom of the floating groove 901 is provided with a floating hole 902 that runs horizontally through the floating block 9 for inserting the floating protrusion 103. After installation, the maximum horizontal gap between the floating hole 902 and the floating protrusion 103 is greater than the maximum gap between the floating shaft 1002 and the floating through hole 102, and does not affect the floating of the floating shaft 1002. The floating block 9 is provided with multiple guide pin holes 903 that correspond to the floating through holes 102 and run vertically through the floating block 9. The guide pin holes 903 are divided into two parts by the floating groove. One part is a smooth hole 90301 that fits with the smooth shaft 1001 with clearance, and the other part is a threaded hole 90302 that is threadedly connected to the threaded shaft 1003. When mounting the mounting plate 101 onto the floating block 9, the mounting plate 101 is inserted into the floating groove 901, and the floating protrusion 103 is inserted into the floating hole 902. At this time, the floating through hole 102 corresponds to the position of the guide pin hole 903, and the end of the threaded guide pin 10 is tapered. Even if the floating through hole 102 and the guide pin hole 903 are not completely aligned, the head of the threaded guide pin 10 can be passed through the threaded hole 90302, the floating through hole 102, and the light hole 90301 in sequence. Then, the threaded shaft 1003 of the threaded guide pin 10 is threadedly connected to the threaded hole 90302, and the light shaft 1001 is limited within the light hole 90301. The floating block 9 is fixed on the chassis corresponding to the rectangular blind-mating connector. After the socket housing 1 is mounted on the floating block 9, when the plug component and the socket component are mated, a radial floating amount of 1.4 to 2.0 can be achieved.

[0036] The connector's plug and socket components have identical insulator structures, meaning the plug and socket insulators are symmetrically arranged. Both insulators are fitted with pins of the same structure, corresponding to the socket and plug pins. The two intermediate components 5 contain a double-ended socket structure 8. When the plug and socket components are engaged, the pin contacts are protected within the intermediate components and the double-ended socket structure. Simultaneously, the socket housing has a floating structure. Therefore, this connector effectively enables reliable signal transmission or current conduction between devices, preventing pin knocking and pinhole damage during engagement. Furthermore, the symmetrical structure of the plug and socket insulators achieves significant structural simplification and cost optimization.

[0037] The dual-ended socket structure and pins are made of existing conductive materials, and will not be described in detail here.

[0038] A locking device 15 is provided on the socket component and the plug component. When the socket component and the plug component are inserted, the locking device 15 is used to securely lock the socket component and the plug component. The locking device is existing technology and will not be described in detail here.

[0039] An embodiment of the connection transmission structure of the present invention, such as... Figures 7a to 7b Figures 7a to 7b As shown, the structure includes plug pins 7 and socket pins 6 with the same structure, as well as a double-ended socket structure 8 that connects the plug pins 7 and socket pins 6. The plug pins 7, socket pins 6, and double-ended socket structure 8 have the same structure as the plug pins 7, socket pins 6, and double-ended socket structure 8 in the rectangular blind-mating connector in the previous embodiment, and will not be described again here.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
