Abstract
Description
Technical Field
[0001] This invention relates to the field of connector technology, and more particularly to a dustproof OD orthogonal optical connector. Background Technology
[0002] With the development of optical communication technology, dust disturbance inside the cabinet can contaminate the fiber optic connectors, affecting fiber optic transmission performance. Therefore, connectors with dustproof doors are increasingly being used for signal transmission.
[0003] However, due to size and structural limitations, commonly used dustproof connectors often employ a two-part, center-opening dustproof door structure, either with an outward or inward opening door. When the door is opened, whether it is an inward or outward opening, dust adhering to the door surface will fall into the fiber optic contact terminal at the moment the two halves of the door open, especially in inward opening structures where dust is more likely to fall into the fiber optic contact terminal. Summary of the Invention

The seat spring is disposed between the seat push block and the seat stop block and is in a compressed state, so that the dustproof door moves towards the opening end with the seat push block without external force, thereby closing the opening end of the seat housing.
[0013] The dustproof door assembly also includes a head spring, which is located at the end of the head push block away from the dustproof door. The other end of the head spring presses against the blind end inside the head housing. The head spring is in a compressed state, so that without external force, the dustproof door moves with the head push block toward the open end of the head housing, thereby closing the open end.
[0014] As an improvement to the above technical solution, the end of the seat spring near the seat push block rests against the connection between the two seat push blocks; the end of the head spring near the head push block rests against the connection between the two head push blocks.
[0015] As an improvement to the above technical solution, a spring post is provided inside the seat spring and the head spring. The spring post is connected to the seat housing and the head housing, so that the seat spring and the head spring can extend and retract along the spring post.
[0016] As an improvement to the above technical solution, the seat housing is inserted between the head housing and the head box, the seat push block protrudes from the seat arc groove, the distance between the head box and the seat housing is less than the height of the seat push block protruding from the surface of the seat housing, and the head push block protrudes from the head arc groove, so that when the seat housing is inserted between the head housing and the head box, the head box pushes the seat push block to move, and the seat housing pushes the head push block to move.
[0017] As an improvement to the above technical solution, seat side plates are respectively provided on both sides of the seat housing, and seat guide grooves are provided on the seat side plates. The seat guide grooves are set as straight grooves, and the seat arc grooves include arc segments and straight segments.

[0030] Example
[0031] like Figures 1-4 As shown, the dustproof OD orthogonal optical connector described in this embodiment includes a backplane connector 1 and a daughterboard connector 2, wherein the backplane connector 1 and the daughterboard connector 2 are plugged into each other;
[0032] The backplate connector 1 includes a base 11 and a housing 12. One end of the housing 12 is mated to the base 11, and the other end is an open end with a built-in dustproof door assembly.
[0033] The dustproof door assembly includes a dustproof door 151, a push block 152, and a stop block 155. The dustproof door 151 is sealed at the opening end of the seat housing 12, and the stop block 155 is disposed at the other end of the seat housing 12. The seat housing 12 is provided with a seat arc groove 154. The push block 152 is connected to the dustproof door 151 and slides along the seat arc groove 154 to realize the opening and closing of the opening end of the seat housing 12.
[0034] The daughterboard connector 2 includes a head housing 23 and a head box 26. The head housing 23 has an open end near the seat housing 12 and is provided with a head dustproof door assembly. The head box 26 is sleeved on the outside of the head housing 23.
[0035] The head dustproof door assembly includes a head dustproof door 271 and a head push block 272. The head dustproof door 271 is connected to the head push block 272. The head housing 26 is provided with a head arc groove 274, and the head push block 272 slides along the head arc groove 274.
[0036] By setting a seat dustproof door 151 and a head dustproof door 271 on the back panel connector 1 and the daughter board connector 2 respectively, bidirectional dust prevention is achieved. The head push block 272 and the seat push block 152 can be moved to open and close the seat dustproof door 151 and the head dustproof door 271. The operation is simple and easy to plug in.
[0037] Two dustproof doors 151 and two push blocks 152 are symmetrically arranged on the seat, and the two push blocks 152 are connected to each other. Two dustproof doors 271 and two push blocks 272 are symmetrically arranged on the head, and the two push blocks 272 are connected to each other. Two arc-shaped grooves 154 on the seat and two arc-shaped grooves 274 on the head are respectively provided.
[0038] By setting the base dustproof door 151 and the head dustproof door 271 as two dustproof doors arranged symmetrically at the top and bottom, the length of each individual base dustproof door 151 and head dustproof door 271 is reduced when opening and closing, and the moving distance of the base push block 152 and head push block 272 is reduced. This controls the length of the back panel connector 1 and the daughter board connector 2, and avoids increasing the length of the back panel connector 1 and the daughter board connector 2 due to accommodating an excessively long base dustproof door 151 and head dustproof door 271.
[0039] The dustproof door assembly also includes a seat spring 153, which is disposed between the seat push block 152 and the seat stop block 155 and is in a compressed state, so that the dustproof door 151 moves toward the opening end with the seat push block 152 without external force, thereby closing the opening end of the seat housing 12.
[0040] The head dustproof door assembly also includes a head spring 273, which is located at the end of the head push block 272 away from the head dustproof door 271. The other end of the head spring 273 presses against the blind end inside the head housing 23. The head spring 273 is in a compressed state, so that without external force, the head dustproof door 271 moves with the head push block 272 toward the open end of the head housing 23, thereby closing the open end.
[0041] When the backplate connector 1 is connected, the head housing 26 of the daughter board connector 2 presses against the seat push block 152 of the backplate connector 1, so that the seat push block 152 overcomes the elastic force of the seat spring 153 and drives the seat dustproof door 151 to slide along the seat arc groove 154, thereby opening the opening end of the seat housing 12. After the backplate connector 1 is pulled out, the head housing 26 no longer restricts the seat push block 152. Under the elastic force of the seat spring 153, the seat push block 152 slides along the seat arc groove 154, thereby closing the opening end of the seat housing 12, thus realizing the automatic opening and closing of the seat dustproof door 151.
[0042] When the daughter board connector 2 is mated, the seat housing 12 of the back plate connector 1 presses against the head push block 272 of the daughter board connector 2. The head push block 272 overcomes the elastic force of the head spring 273 and drives the head dustproof door 271 to slide along the head arc groove 274, thereby opening the opening end of the head housing 23. When the back plate connector 1 is separated, the head push block 272 is no longer restricted by the seat housing 12. Under the elastic force of the head spring 273, the head push block 272 slides along the head arc groove 274 to close the opening end of the head housing 23, thereby achieving the automatic opening and closing of the seat dustproof door 151.
[0043] The seat spring 153 rests near the seat push block 152 at one end, which is located at the connection between the two seat push blocks 152; the head spring 273 rests near the head push block 272 at one end, which is located at the connection between the two head push blocks 272. This ensures that the elastic force of the seat spring 153 and the head spring 273 is more evenly distributed on the two seat push blocks 152 and the two head push blocks 272, preventing uneven force distribution on the two seat push blocks 152 or the two head push blocks 272, which could cause them to jam with the seat arc groove 154 and the head arc groove 274, making it difficult for them to slide.
[0044] The seat spring 153 and the head spring 273 are provided with spring posts to constrain the seat spring 153 and the head spring 273. The spring posts are connected to the seat housing 12 and the head housing 23, so that the seat spring 153 and the head spring 273 can extend and retract along the spring posts.
[0045] The seat housing 12 is inserted between the head housing 23 and the head box 26. The seat push block 152 protrudes from the seat arc groove 154. The distance between the head box 26 and the seat housing 12 is less than the height of the seat push block 152 protruding from the surface of the seat housing 12. The head push block 272 protrudes from the head arc groove 274. When the seat housing 12 is inserted between the head housing 23 and the head box 26, the head box 26 pushes the seat push block 152 to move, and the seat housing 12 pushes the head push block 272 to move.
[0046] When the backplate connector 1 is mated, the head housing 26 of the daughter board connector 2 presses against the seat push block 152 of the backplate connector 1, causing the seat push block 152 to drive the seat dustproof door 151 to slide along the seat arc groove 154, thereby opening the opening end of the seat housing 12. After the backplate connector 1 is pulled out, the head housing 26 no longer restricts the seat push block 152, and moves the seat push block 152 to slide along the seat arc groove 154, thereby closing the opening end of the seat housing 12. This effectively blocks dust, is easy to operate, and can further reduce production costs.
[0047] When the daughter board connector 2 is mated, the seat housing 12 of the back plate connector 1 presses against the head push block 272 of the daughter board connector 2, causing the head dustproof door 271 to slide along the head arc groove 274, thereby opening the opening end of the head housing 23; when the back plate connector 1 is separated, the head push block 272 is no longer restricted by the seat housing 12, and the head push block 272 slides along the head arc groove 274 to close the opening end of the head housing 23; thus achieving effective dust protection, simple operation, and further reducing production costs.
[0048] By setting a base dustproof door 151 and a head dustproof door 271 on the backplane connector 1 and daughterboard connector 2 respectively, bidirectional dust prevention is achieved. Furthermore, the base dustproof door 151 and head dustproof door 271 are automatically opened by pushing the head push block 272 and the base push block 152 during insertion through the base housing 12 and the head housing 26. The operation is simple and easy to insert.
[0049] The seat housing 12 is provided with seat side plates 13 on both sides. The seat side plates 13 are provided with seat guide grooves 156. The seat guide grooves 156 are straight grooves. The seat arc grooves 154 include arc segments and straight segments, and the straight segments of the seat arc grooves 154 correspond to the seat guide grooves 156. The seat push block 152 can only move along the seat guide grooves 156. When the seat dust door 151 enters the arc segment, the opening end of the seat housing 12 is closed; when the seat dust door 151 enters the straight segment, the opening end of the seat housing 12 is opened.
[0050] The head arc groove 274 includes an arc segment and a straight segment. The head push block 272 can only move in the straight segment. The head dustproof door 271 enters the straight segment when it is open and enters the arc segment when it is closed.
[0051] The seat housing 12 is provided with a seat positioning boss 157, and the seat side plate 13 is provided with a seat positioning groove that cooperates with the seat positioning boss 157; the head housing 23 is provided with a head positioning boss 276, and the head box 26 is provided with a head positioning groove 278 that cooperates with the head positioning boss 276; all of which serve a positioning function.
[0052] The head box 26 is provided with head side plates 24 on both sides. The head side plates 24 enclose the two sides of the head box 26 to prevent dust. The head side plates 24 are provided with side plate positioning grooves 279, which cooperate with the head positioning bosses 276.
[0053] The sub-board connector 2 also includes a top cover plate 21 and a bottom cover plate 22, which are connected to the upper and lower ends of the head housing 26, respectively, for sealing and dustproofing the upper and lower ends of the head housing 26.
