[0040] The utility model provides an LC adapter 100, comprising a shell 10, a dust cover 20 and a reset sheet 30. The shell 10 comprises a shell body 11 and a buckle cover 12. A first receiving groove 101 is formed at one end of the shell body 11. A groove wall portion of one side of the first receiving groove 101 adjacent to the groove is penetrated to form an installation opening 111. A wall surface of the installation opening 111 close to the groove of the first receiving groove 101 is set as a step surface 106. The buckle cover 12 is installed at the installation opening 111 and matched with the step surface 106. One end of the dust cover 20 is rotatably installed on the groove wall of the first receiving groove 101. The reset sheet 30 has a fixed end 31 and a top end 32 opposite to each other. The fixed end 31 is clamped between the buckle cover 12 and the step surface 106. The top end 32 abuts against the inner side surface of the dust cover 20, so that the dust cover 20 has a tendency to cover the groove of the first receiving groove 101.
[0041] In some embodiments of the present invention, a first receiving groove 101 and a second receiving groove 103 are respectively formed at two opposite ends of the housing 10 . The housing 10 is further provided with an optical fiber channel 104 communicating with the first receiving groove 101 and the second receiving groove 103 .
[0042] In some embodiments of the utility model, a rotating shaft 21 is provided at one end of the dust cover 20, and the rotating shaft 21 is rotatably mounted on one side of the first receiving groove wall near the notch, and the dust cover 20 has a closed state and an open state. The dust cover 20 covers the notch of the first receiving groove 101 in the closed state, and the dust cover 20 is close to the buckle cover 12 in the open state. The rotating shaft 21 is generally formed integrally with the dust cover 20, which is convenient for installation and compact in structure.
[0043] The housing 10 and the dust cover 20 are generally made of plastic, specifically polyethylene (PE), polypropylene (PP), polycarbonate (PC), etc., which have good mechanical properties, heat resistance and corrosion resistance. The optical fiber channel 104 is generally made of a ceramic tube, a glass tube, etc. The reset sheet 30 is generally made of a metal sheet, of course, it can also be a plastic sheet, which is not specifically limited here.
[0044] In the above-mentioned housing 10 , the first accommodating grooves 101 , the second accommodating grooves 103 and the optical fiber channels 104 can be arranged in one group, two groups, three groups or more, depending on the specific situation, and no specific limitation is made here.
[0045] The above-mentioned step surface can be formed on the side close to the mounting opening and close to the rotating shaft 21, or it can be formed on the side of the mounting opening away from the rotating shaft 21. The shape of the reset plate 30 is generally set to be curved, that is, the reset plate 30 extends along the curve from the fixed end 31 to the top end 32, and the curvature of the reset plate 30 is set according to the rotation angle of the dust cover 20 from the open state to the closed state. In some embodiments of the utility model, the end of the top end 32 is bent in the direction away from the dust cover 20. The curved top end 32 has a small sliding resistance on the inner side of the dust cover 20, and the user can insert the optical fiber end more smoothly. The curvature of the end of the top end 32 in the direction away from the dust cover 20 needs to keep the arc surface tangent to the surface of the dust cover 20 as much as possible, and no specific limitation is made here.
[0046] Through the above scheme, when the optical fiber end is inserted into the first receiving groove 101, the optical fiber end presses against the dust cover 20, the dust cover 20 rotates, and the reset plate 30 is compressed and deformed until the reset plate 30 is pressed against the groove wall of the first receiving groove 101 by the dust cover 20. When the optical fiber end is pulled out, the reset plate 30 drives the dust cover 20 to reset.
[0047] The present solution uses a reset sheet 30 to reset the dust cover 20, which occupies little space and has a highly compact structure. During assembly, after the dust cover 20 is assembled into the first accommodating groove 101, the fixed end 31 of the reset sheet 30 can be pre-installed on the step surface 106, and finally the buckle cover 12 is installed. The reset sheet 30 is clamped between the step surface 106 and the buckle cover 12, which is convenient for assembly.
[0048] In some embodiments of the utility model, the dust cover 20 is provided with an inner recess 22 in the direction of the optical fiber channel 104, and the reset sheet 30 is provided with a corresponding avoidance opening 33. When the dust cover 20 is in the open state, the inner recess 22 is received in the avoidance opening 33. In this way, the inner recess 22 is used to avoid the optical fiber. When the optical fiber end is inserted into the first receiving groove 101, the outer shell of the optical fiber end abuts against the dust cover 20, and the optical fiber is spaced from the inner recess 22. When the optical fiber end is fully inserted, the inner recess 22 passes through the avoidance opening 33, and the structure is compact.
[0049] Furthermore, in some embodiments of the present invention, a receiving groove 127 is provided on the inner wall surface of the buckle cover 12 to receive the inner recess 22. In this way, the inner recess 22 passes through the avoidance opening 33 and is received in the receiving groove 127, and the overall structure is more compact, which is conducive to the compactness of the LC adapter 100.
[0050] In some embodiments of the present invention, the width of the avoidance opening 33 near the abutting top 32 is smaller than the width of the avoidance opening 33 near the fixed end 31. With this arrangement, when the abutting top 32 is compressed and the reset sheet 30 is deformed, the actual width of the portion of the reset sheet 30 near the fixed end 31 is wider, more materials participate in the deformation, the stress distribution is more uniform, the occurrence of local high stress areas is reduced, and the fatigue life is longer.
[0051] The buckle cover 12 can be installed on the mounting opening 111 in various ways. In some embodiments of the present invention, guard plates 123 are provided on opposite sides of the buckle cover 12, and assembly grooves 119 are provided on opposite sides of the shell 11, and the guard plates 123 are snap-fitted into the corresponding assembly grooves 119.
[0052] In other embodiments of the utility model, the installation opening 111 is provided with an assembly opening 113 along the wall away from the optical fiber channel 104, and a latch 121 is provided at one end of the buckle cover 12, and the latch 121 is engaged in the assembly opening 113, and the buckle cover 12 abuts against the reset sheet 30. In this way, when assembling, after the reset sheet 30 is placed in place, the latch 121 is inserted into the assembly opening 113, and the buckle cover 12 can limit the reset sheet 30, and then the buckle cover 12 is installed in place, and when disassembling, the reset sheet 30 can be directly removed after the buckle cover 12 is removed, and both disassembly and assembly are relatively convenient.
[0053] In this embodiment, the specific installation methods of the buckle cover 12 are various. In some embodiments of the utility model, a through hole is provided on the side of the buckle cover 12 away from the tongue 121, and a threaded hole is provided at the position of the housing 11 near the installation opening 111, and the screw passes through the through hole and is screwed into the threaded hole. In other embodiments of the utility model, an elastic buckle 122 is provided on the side of the buckle cover 12 away from the tongue 121, and a buckle interface 118 is formed on the edge of the installation opening 111 away from the assembly opening 113, and the elastic buckle 122 is engaged with the buckle interface 118. In this way, when the buckle cover 12 is installed to the housing 11, the tongue 121 at one end of the buckle cover 12 is first inserted into the assembly opening 113, and then the other end of the buckle cover 12 is covered, so that the elastic buckle 122 is engaged with the buckle interface 118. In this way, the two ends of the buckle cover 12 are installed in sequence, the difficulty of assembly and disassembly is small, and the installation can be achieved in one step, and the damage rate of parts caused by assembly is low, which can save production material costs and assembly time costs.
[0054] In some embodiments of the utility model, a mounting opening 113 is provided on one side wall of the mounting opening 111 away from the bottom of the first receiving groove 101; a buckle interface 118 is provided on one side wall of the mounting opening 111 away from the groove of the first receiving groove 101; the buckle cover 12 is bent at opposite ends adjacent to the latch 121 to form a guard plate 123, and mounting grooves 119 are correspondingly provided on opposite sides of the housing 11, and a guard plate 123 is assembled in an assembly groove 119. Through the above scheme, the buckle cover 12 is provided with structures that cooperate with the housing 11 in four directions, and the connection between the two is more stable.
[0055] Furthermore, in some embodiments of the present invention, the inner side surface of the guard plate 123 is provided with a convex clamp, and the groove wall of the assembly groove 119 is provided with a clamp hole 1191, and the convex clamp is clamped in the clamp hole 1191. This further improves the connection stability between the buckle cover 12 and the housing 11, and when installing the buckle cover 12, the clamping tongue 121 is first inserted into the assembly opening 113, and the assembly opening 113 can play a certain role in limiting the movement and flipping of the buckle cover 12. At this time, the assembly opening 113 and the hand of the assembler jointly form a stable support for the buckle cover 12, so that the guard plate 123 can be smoothly clamped in the assembly groove 119.
[0056] In some embodiments of the utility model, the wall surface of the installation opening 111 is further provided with a buckle protrusion 1181, which is located on the side of the buckle interface 118 away from the first receiving groove 101, and the elastic buckle 122 includes a hook portion 1221 and a groove portion 1222, the hook portion 1221 is buckled in the buckle interface 118, and the groove portion 1222 cooperates with the buckle protrusion 1181. In this way, when the buckle cover 12 is pressed until the hook portion 1221 is buckled in the buckle interface 118, the buckle protrusion 1181 cooperates in the groove portion 1222, which limits the buckle cover 12 from further moving in the direction close to the first receiving groove 101, avoiding the problem of pressure damage of internal components.
[0057] The reset sheet 30 can be fixed by pressing and clamping the buckle cover 12 and the wall of the first receiving groove 101, limiting the movement of the fixed end 31 in the direction of approaching and moving away from the optical fiber channel 104. In some embodiments of the utility model, the reset sheet 30 is provided with lugs 34 on opposite sides of the fixed end 31, and the groove walls of the first receiving groove 101 adjacent to the installation opening 111 are respectively provided with limit baffles 114, and the limit baffles 114 limit the lugs 34 between the buckle cover 12 and the step surface 106. Such a setting has a good limiting effect and high structural stability.
[0058] In some embodiments of the utility model, a first partition 116 is provided in the housing 11, and the first partition 116 divides the space in the housing 11 into pairs of first accommodating grooves 101, and multiple first accommodating grooves 101 are all connected to the installation port 111, and the limit baffle 114 is formed at one end of the first partition 116 close to the installation port 111; the reset pieces 30 are arranged in pairs, and the adjacent side lugs 34 of the two pairs of reset pieces 30 are integrally connected, and an assembly interval 35 for assembling the limit baffle 114 is formed between the two pairs of reset pieces 30. In this way, an LC adapter 100 can connect more than two optical fibers, and has better applicability. The reset pieces 30 are arranged in pairs, which can reduce the assembly steps, save the trouble of assembling the reset pieces 30 one by one, and have higher assembly efficiency.
[0059] Furthermore, in some embodiments of the present invention, the housing 11 further includes a second partition 117, which is disposed between two adjacent and unpaired first accommodating grooves 101, and an anti-fool baffle 115 is disposed at one end of the second partition 117 facing the mounting opening 111, and the width of the anti-fool baffle 115 is greater than the assembly interval 35. In this arrangement, the paired reset sheets 30 cannot be installed on both sides of the anti-fool baffle 115, thereby avoiding mis-installation.
[0060] In some embodiments of the utility model, a rotating shaft 21 is provided on opposite sides of one end of the dust cover 20, and two groove side walls of the first receiving groove 101 adjacent to the installation opening 111 are respectively provided with a shaft groove 105, and the shaft groove 105 penetrates on one side close to the installation opening 111, and the rotating shaft 21 is installed in the shaft groove 105, and the fixed end 31 of the reset piece 30 is limited to one side of the rotating shaft 21. In this way, when assembling, after the rotating shaft 21 is assembled into the shaft groove 105, the fixed end 31 of the reset piece 30 is placed on the side through which the shaft groove 105 penetrates, and finally the buckle cover 12 is installed, and the reset piece 30 is clamped between the groove wall of the first receiving groove 101 and the buckle cover 12, and the buckle cover 12 limits the rotating shaft 21 in the shaft groove 105 through the reset piece 30, which is convenient for disassembly and assembly, and has good structural stability.
[0061] In some embodiments of the present invention, a side of the buckle cover 12 facing the first receiving groove 101 is provided with an escape groove 126 to escape the bent portion of the reset sheet 30. With this arrangement, when the dust cover 20 is opened, the top portion is received in the escape groove 126, and the overall structure is further compacted, which is conducive to the compactness of the LC adapter 100.
[0062] In some embodiments of the present invention, a limiting protrusion 125 is further provided at one end of the buckle cover 12 close to the assembly opening 113, and a limiting groove 1121 is correspondingly provided on a side wall of the installation opening 111 away from the bottom of the first receiving groove 101, the limiting groove 1121 penetrates in a direction away from the first receiving groove 101, and the limiting protrusion 125 is assembled in the limiting groove 1121. In this way, the limiting groove 1121 can further limit the buckle cover 12, thereby improving the structural stability.
[0063] In some embodiments of the utility model, a lap protrusion 107 is formed on one side of the two side walls of the first receiving groove 101 adjacent to the installation opening 111 and close to the groove opening, and a side of the lap protrusion 107 facing the groove bottom of the first receiving groove 101 is set as a lap bevel 108, and the lap bevel 108 abuts against the outer side surface of the dust cover 20, and the lap bevel 108 is inclined from the direction away from the buckle cover to the direction close to the groove bottom of the first receiving groove 101. In this way, the outer side surface of the dust cover 20 fits with the lap protrusion 107, and the peripheral side surface of the dust cover 20 fits with the groove wall of the first receiving groove 101, and the dustproof effect is better.
[0064] In some embodiments of the utility model, a protective platform 109 is convexly provided on one side of the groove wall of the first receiving groove 101 near the groove opening, and a dust-proof boss 23 is connected to one end of the dust cover 20 near the installation opening, and the dust-proof boss 23 is located between the outer side of the dust cover 20 and the protective platform 109. In this way, the protective platform 109 can prevent the light end from hitting the rotating shaft 21 of the dust cover 20 when the light end is inserted, and prevent the rotating shaft 21 from breaking due to a large radial force, and the dust-proof boss 23 can fill the gap between the dust cover 20 and the protective platform 109, and prevent dust from accumulating between the dust cover 20 and the protective platform 109. In particular, in some embodiments, the dust cover 20 is arranged obliquely, and the gap between the dust cover 20 and the protective platform 109 is larger, so it is more necessary to provide the dust-proof boss 23.
[0065] The dustproof boss 23 and the dustproof cover 20 are generally connected in one piece. Of course, they can also be connected by bonding, hot melting or other methods, which are not limited here.
