Description

Technical Field

[0001] This invention relates to the field of optical fiber communication, and more specifically, to an integrated connector assembly and its adapter. Background Technology

[0002] In related technologies, fiber optic connector adapters are usually designed to connect to connectors of different specifications. Different connectors typically have different fiber optic mating parts, but they generally use the same connection structure to connect and fix with the adapter. When the connection structures of different connectors are different, it is not easy to connect them with adapters of the same specification.

[0003] Furthermore, when the optical distribution box in the same distribution network center encounters optical cables with different connector structures, an additional distribution box needs to be configured, which seriously affects the cost and distribution efficiency of the network center. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an integrated connector assembly and its adapter, which addresses the above-mentioned deficiencies of the prior art.

[0005] The technical solution adopted by the present invention to solve its technical problem is: to construct an integrated adapter, including a base, a connecting sleeve, and a locking component;

[0006] The connecting sleeve is fitted onto the body, and the locking assembly is installed between the body and the connecting sleeve, and can move back and forth axially between the locked position and the unlocked position.

[0007] The base is provided with a plug-in position for the connector to be inserted, and there is a driving space between the base and the connecting sleeve to drive the locking assembly to move to the locking position when the connector is inserted.

[0008] The base and the connecting sleeve are provided with locking structures for locking different inserted connectors. When the locking component is in the locking position, it limits the position of the connector insertion and keeps the inserted connector locked with the locking structure.

[0009] In some embodiments, the connector includes an optical fiber assembly, an inner sleeve sleeved outside the optical fiber assembly, and an outer sleeve sleeved outside the inner sleeve; the base includes a insertion tube and a connecting tube outside the insertion tube.

[0010] The insertion tube is used for inserting the optical fiber assembly. There is a gap between the insertion tube and the connecting tube for inserting the inner sleeve. There is a gap between the connecting tube and the connecting sleeve for inserting the outer sleeve. When the outer sleeve is inserted between the connecting tube and the connecting sleeve, it drives the locking assembly to switch from the unlocked position to the locked position.

[0011] In some embodiments, the locking assembly includes a first locking member, a second locking member, a first elastic member, and a second elastic member. The first locking member and the second locking member are movably connected. The first elastic member abuts between the first locking member and the second locking member and provides an elastic force to the first locking member away from the second locking member. The second elastic member abuts between the second locking member and the seat and provides an elastic force to the second locking member away from the seat.

[0012] In some embodiments, the first locking member and the second locking member are sleeved together and are provided with a locking structure to prevent the first locking member and the second locking member from disengaging, and the base is provided with a limiting structure to limit the movement range of the first locking member and the second locking member.

[0013] In some embodiments, the locking assembly further includes an unlocking portion connected to the second locking member, the unlocking portion extending out of the connecting sleeve to move the locking assembly toward the unlocking position and disengage the connector from the adapter.

[0014] In some embodiments, the connector includes a first connector, the locking structure includes an elastic buckle disposed on the base, the locking component abuts against the elastic buckle in the locked position to keep the elastic buckle engaged with the first connector, and the locking component is disengaged from the elastic buckle in the unlocked position.

[0015] In some embodiments, the outer wall surface of the inner sleeve of the first connection is provided with a groove or protrusion for the elastic buckle to engage, and the second locking member is provided with a pressing part. When in the locking position, the pressing part abuts against the elastic buckle to prevent the elastic buckle from loosening.

[0016] In some embodiments, the connector includes a second connector, and the locking structure includes a locking position disposed on the inner wall surface of the connecting sleeve. When the locking assembly is in the locked position, the locking position engages with the second connector, and the locking assembly provides a spring force to maintain engagement. After the locking position is separated from the second connector, the locking assembly provides an outward spring force to the second connector and resets to the unlocked position.

[0017] In some embodiments, the second connector further includes a sleeve sleeve fitted on the outside, the sleeve sleeve having a snap-fit ​​portion that engages with the snap-fit ​​position, and the inner wall surface of the connector sleeve having a guide portion for the snap-fit ​​portion to be axially snapped into the snap-fit ​​position, the guide portion being circumferentially offset from the snap-fit ​​portion, allowing the sleeve sleeve to rotate so that the snap-fit ​​portion engages or disengages from the snap-fit ​​position.

[0018] An integrated connector assembly includes the integrated adapter and a connector head that plugs into the integrated adapter.

[0019] The integrated connector assembly and adapter of the present invention have the following advantages: the base and the connecting sleeve are provided with locking structures for locking different inserted connectors. When the locking assembly is in the locking position, the locking structure can limit the insertion position of the connector and keep the inserted connector locked with the locking structure. When connectors of different specifications are inserted, the corresponding connectors can be prevented from disengaging, thereby improving the versatility and reliability of the adapter and facilitating the integration of different fiber optic connectors.

[0032] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] like Figure 1 As shown, the integrated connector assembly in a preferred embodiment of the present invention includes an adapter 1, a connector 2, and a connecting cable 3. The adapter 1 can be adapted to different connectors 2. In this embodiment, the adapter 1 can be adapted to a first connector 2a and a second connector 2b. The first connector 2a and the second connector 2b are provided with different connection structures, which can be locked with different positions of the locking structure on the adapter 1 to achieve connection and fixation of different connectors 2. The adapter 1 has a higher degree of integration, which can improve the versatility of the adapter 1 and reduce the types of adapters 1. After the connector 2 is plugged into one end of the adapter 1, it can be connected to the optical fiber on the connecting cable 3 plugged into the other end of the adapter 1 to realize data transmission.

[0034] Combination Figures 2 to 8 As shown, the integrated adapter 1 includes a base 11, a connecting sleeve 12, and a locking assembly 13. The connecting sleeve 12 is sleeved on the outside of the base 11 and locks with the locking sleeve 13, thus locking and fixing the connecting sleeve 12 to the base 11. The locking assembly 13 is installed between the base 11 and the connecting sleeve 12 and can move back and forth axially between the locked position A and the unlocked position B. Typically, the connecting sleeve 12 can be screwed to the locking sleeve or snap-fitted together.

[0035] The base 11 is provided with a insertion position for the connector 2 to be inserted. Specifically, the base 11 includes a insertion tube 111 and a connecting tube 112 outside the insertion tube 111. The insertion tube 111 and the connecting tube 112 are spaced apart to form a space for the connector 2 to be inserted between the insertion tube 111 and the connecting tube 112. There is a driving space between the base 11 and the connecting sleeve 12 to drive the locking component 13 to move to the locking position A when the connector 2 is inserted, so that the locking component 13 is switched to the locking position A and the connector 2 is locked and fixed.

[0036] The base 11 and the connecting sleeve 12 are provided with locking structures for locking different inserted connectors 2. When the locking assembly 13 is in the locking position A, the locking structure can limit the insertion position of the connector 2 and keep the inserted connector 2 locked with the locking structure. When connectors 2 of different specifications are inserted into the adapter 1, the locking structure on the base 11 and the locking structure on the connecting sleeve 12 can lock the different connectors 2 respectively, which can prevent the corresponding connectors 2 from falling off, improve the versatility and reliability of the adapter 1, and facilitate the integration of different fiber optic connectors 2.

[0037] The connector 2 includes an optical fiber assembly 21, an inner sleeve 22 sleeved outside the optical fiber assembly 21, and an outer sleeve 23 sleeved outside the inner sleeve 22. The inner sleeve 22 and the outer sleeve 23 can be an integral structure or separate structures connected by screws or snaps. The insertion tube 111 is used to insert the optical fiber assembly 21. The optical fiber on the optical fiber assembly 21 is used for transmission. There is a gap between the insertion tube 111 and the connecting tube 112 for the inner sleeve 22 to be inserted. There is a gap between the connecting tube 112 and the connecting sleeve 12 for the outer sleeve 23 to be inserted. When the outer sleeve 23 is inserted between the connecting tube 112 and the connecting sleeve 12, it drives the locking component 13 to switch from the unlocked position B to the locked position A, and connects the inner sleeve 22 and the outer sleeve 23 to the base body 11.

[0038] The connector 2, the base 11, and the connecting sleeve 12 are interconnected in a multi-layered sleeve manner from the inside out. Sealing rings can be added at the mating positions of each sleeve surface to improve the stability and sealing of the connector 2 during insertion. Simultaneously, a sealing ring can also be provided on the outer end face of the locking assembly 13 to abut against the end face of the outer sleeve 23 for sealing. During insertion, this allows the connector 2 to connect with the adapter 1, enabling the locking assembly 13 to move stably inward to the locking position A, and also provides cushioning during insertion to prevent damage.

[0039] Specifically, in combination Figures 4 to 6 ,and Figure 9 As shown, in some embodiments, the locking assembly 13 includes a first locking member 131, a second locking member 132, a first elastic member 133, and a second elastic member 134. The first locking member 131 and the second locking member 132 are movably connected. The first elastic member 133 abuts against the first locking member 131 and the second locking member 132, providing an elastic force to the first locking member 131 away from the second locking member 132. The second elastic member 134 abuts against the second locking member 132 and the seat 11, providing an elastic force to the second locking member 132 away from the seat 11.

[0040] Furthermore, a limiting structure 1123 is provided on the seat 11 to limit the movement range of the first locking member 131 and the second locking member 132. Preferably, the limiting structure 1123 is provided on the connecting pipe 112, and the locking assembly 13 is sleeved on one end of the connecting pipe 112. The limiting structure 1123 includes two abutting parts spaced apart on the side wall of the connecting pipe 112, and the abutting part near the end is lower, so that the locking assembly 13 can be sleeved on and abuts the end of the first locking member 131 after sleeved on to prevent it from coming off. The other abutting part abuts against the second elastic member 134 and limits the position of the second locking member 132 after it is retracted.

[0041] Combination Figure 2 , 3 As shown in Figures 5 and 6, when the connector 2 is inserted, it will first abut against the outer end face of the first locking member 131. During the continued insertion process, it will push the first locking member 131 to move inward and compress the first elastic member 133 that abuts against the first locking member 131 and the second locking member 132. Under the elastic force of the first elastic member 133, it will drive the second locking member 132 to move inward. When the second locking member 132 moves inward, it will press against the second elastic member 134 that is provided between the second locking member 132 and the base 11.

[0042] When the second elastic member 134 is compressed to the point that the second locking member 132 abuts against the seat 11, the second locking member 132 stops moving. As the connector 2 continues to be inserted inward, it will push the first locking member 131 to continue to move inward and move inward relative to the second locking member 132 until the connector 2 is inserted into place. Then the connector 2 can be locked and fixed with the adapter 1 and remain in the inserted state.

[0043] In this embodiment, the first locking member 131 and the second locking member 132 are sleeved together and can move relative to each other in the axial direction. Preferably, the first locking member 131 and the second locking member 132 are provided with a locking structure to prevent them from disengaging from each other. When the first locking member 131 and the second locking member 132 are sleeved together, the locking structure engages with each other. The locking structure may include a latch 1311 provided on the first locking member 131 and a locking groove 1321 provided on the second locking member 132 for the latch 1311 to engage. The locking groove 1321 is arranged axially, allowing the latch 1311 to slide along the locking groove 1321, thereby realizing relative movement between the first locking member 131 and the second locking member 132 in the axial direction.

[0044] The locking assembly 13 also includes an unlocking part 135 connected to the second locking member 132. The unlocking part 135 can be an integral structure with the second locking member 132, or it can be connected and fixed to the second locking member 132 and extend out of the connecting sleeve 12 for user operation. When the unlocking part 135 extends out of the connecting sleeve 12, it can drive the second locking member 132 to move closer to the first locking member 131. During the process of moving closer to the first locking member 131, the first elastic member 133 will be compressed. After the first elastic member 133 is compressed, the second locking member 132 can press against the first locking member 131 and move to the unlock position B, allowing the first locking member 131 to drive the connector 2 to disengage from the adapter 1, and then pull it out after unlocking from the adapter 1.

[0045] Adapter 1 can be matched with first connector 2a and second connector 2b. It can be understood that first connector 2a and second connector 2b have two different structures, and each structure, based on its own principle, can be appropriately sized to correspond to various specifications of connector 2. To match different connector 2, the locking structure can include different locking methods to lock connector 2 with different structures.

[0046] Specifically, such as Figure 1 As shown, the outer wall of the inner sleeve 22 of the first connector 2a is provided with a slot 221, which allows the locking structure to lock the first connector 2a. The locking component 13 can keep the locking structure locked with the slot 221, and the unlocking part 135 can also be used to drive the first connector 2a out of the adapter 1. The outer sleeve 23 of the second connector 2b is provided with a sleeve tube 24, which is provided with a snap-fit ​​part 241. Preferably, the snap-fit ​​part 241 is provided on the outer wall of the sleeve tube 24, but it can also be provided on the inner wall of the sleeve tube 24. The sleeve tube 24 is fitted onto the outside of the connecting sleeve 12, and the snap-fit ​​position 121 is provided on the outside of the connecting sleeve 12, which allows the locking structure to lock the second connector 2b. The locking component 13 can keep the locking structure locked with the snap-fit ​​part 231, and the unlocking part 135 can also be used to drive the first connector 2a out of the adapter 1.

[0047] Combination Figure 2 , 3 As shown, in order to correspond to the slot 221 of the first connector 2a, the locking structure includes an elastic buckle 1121 disposed on the base 11. Specifically, the elastic buckle 1121 is disposed on the connecting tube 112. When the locking component 13 is in the locking position A, it abuts against the elastic buckle 1121 to keep the elastic buckle 1121 engaged with the connector 2. When the locking component 13 is in the unlocking position B, it is disengaged from the elastic buckle 1121.

[0048] Preferably, when the first connector 2a is inserted, the inner sleeve 22 is inserted between the insertion tube 111 and the connecting tube 112. The inner sleeve 22 can press and deform the elastic buckle 1121 outward, allowing the elastic buckle 1121 to slide along the outer wall surface of the inner sleeve 22 until the groove 221 of the inner sleeve 22 slides to the position of the elastic buckle 1121, and the elastic buckle 1121 is engaged in the groove 221 under the action of elastic force.

[0049] Furthermore, the second locking member 132 is provided with a pressing part 1322. After the elastic buckle 1121 is inserted into the slot 221, the locking assembly 13 also changes to the locking position A. At this time, the pressing part 1322 presses against the elastic buckle 1121 to prevent the elastic buckle 1121 from loosening, thus maintaining the connection between the first connector 2a and the adapter 1.

[0050] When it is necessary to pull out the first connector 2a, pull the unlocking part 135 to move the second locking part 132 in the direction of pulling out the first connector 2a, so that the pressing part 1322 and the elastic buckle 1121 are separated. At this time, the elastic buckle 1121 no longer has the pressure. When pulling out the first connector 2a, the slot 221 disengages from the elastic buckle 1121, so that the first connector 2a can be pulled out and removed.

[0051] Understandably, in other embodiments, the slot 221 on the first connector 2a can also be replaced with a protrusion, and the elastic buckle 1121 is provided with an indentation for the protrusion to be engaged, so as to achieve mutual engagement.

[0052] Furthermore, combined Figure 10 , 11 As shown, in order to correspond to the snap-fit ​​portion 241 of the second connector 2b, the locking structure includes a snap-fit ​​position 121 provided on the inner wall surface of the connecting sleeve 12. Specifically, the snap-fit ​​portion 241 is provided on the outer wall surface of the sleeve 24, and the inner wall surface of the connecting sleeve 12 is provided with a guide portion 122 for the snap-fit ​​portion 241 to snap into the snap-fit ​​position 121 along the axial direction. Preferably, the guide portion 122 is a guide groove, so that the snap-fit ​​portion 241 snaps into the snap-fit ​​position 121 after being snapped in along the axial direction.

[0053] In this embodiment, when the second connector 2b is inserted, the outer sleeve 23 of the second connector 2b abuts against the first locking member 131, causing the locking assembly 13 to shift to the locking position A. Simultaneously, the outer sleeve 23 and the sleeve 24 are inserted between the connecting pipe 112 and the connecting sleeve 12, and the snap-fit ​​portion 241 moves along the guide portion 122 on the inner wall of the connecting sleeve 12. In other embodiments, the locking assembly 13 can also shift to the locking position A by the sleeve 24 abutting against the first locking member 131, or by the outer sleeve 23 and the sleeve 24 simultaneously abutting against the first locking member 131.

[0054] The second connector 2b also includes a reset member that engages with the engagement position 121 and provides circumferential rotational force to the sleeve 24. Under the action of the guide portion 122, the sleeve 24 reverses, causing the engagement portion 241 to be misaligned with the engagement position 121 and compressing the reset member.

[0055] When the locking assembly 13 is in the locked position A, the sleeve 24 rotates under the action of the reset member, and the locking part 241 is engaged in the locking position, so that the locking position 121 can engage with the locking part 241 on the second connector 2b. After the second connector 2b is released, the locking assembly 13 has an outward reset elastic force, which can provide an elastic force to keep the second connector 2b engaged with the locking position 121.

[0056] When it is necessary to remove the second connector 2b, rotate the sleeve 24 in the opposite direction to separate the locking position 121 from the locking part 241 on the connector 2. Then, the locking component 13 can be unlocked to apply force in the pulling direction, causing the second connector 2b to come out. The locking component 13 also provides an outward elastic force to the second connector 2b. The locking component 13 then returns to the unlocked position B, and the second connector 2b also comes out of the adapter 1.

[0057] The snap-fit ​​part 241 is a protrusion, the engaging part is an inner groove, and the guide part 122 is a guide groove. Understandably, the snap-fit ​​part 241 on the second connector 2b can also be interchanged with the engaging part 121 on the inner wall surface, as long as the engaging connection can be achieved.

[0058] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0059] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
