Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a connector and a connector head. Background Technology

[0002] Currently, fiber optic connectors generally use LC-type fiber optic movable connectors. The International Electrotechnical Commission (IEC) has established a series of regulations regarding the interface type and mating dimensions of LC-type fiber optic movable connectors. This type of connector consists of a connector head and an adapter. The connector head has a spring-loaded clip, and the adapter's slot mates with the spring-loaded clip to achieve the connection between the connector head and the adapter. However, the spring-loaded clip needs a relatively large radial dimension along the optical axis to allow for sufficient deformation, enabling it to disengage from the slot to separate the connector head or adapter, and to snap into the slot to ensure the connection. Therefore, LC-type fiber optic movable connectors still have a relatively large radial dimension along the optical axis, limiting space utilization. Summary of the Invention

[0003] This application provides a connector and a connector head that facilitates a reduction in the size of the connector head in the radial direction of the optical axis.

[0004] A first aspect of this application provides a connector capable of partially inserting an adapter along a first direction. This connector includes a main body and a pull-out portion. The main body includes a housing and a first guide member. The housing has a mounting cavity for at least partially accommodating a plug for mating with the adapter. The first guide member is fixedly disposed on one side of the housing. The housing has a positioning groove on the side where the first guide member is disposed, the positioning groove for accommodating a movable connecting post on the adapter to restrict the housing and the adapter in the first direction. The pull-out portion includes a pull-out member and a second guide member. The second guide member is fixed to the pull-out member and slidably engages with the first guide member along the first direction. The pull-out member has a guide ramp inclined to the first direction. When the pull-out member moves relative to the housing parallel to the first direction, the guide ramp moves from a first position to a second position to drive the movable connecting post out of the positioning groove.

[0005] The connector features a positioning groove that engages with the adapter's movable connecting post to lock the connector and adapter in a first direction. When the connector and adapter are used for fiber optic connection, this first direction is the optical axis direction. The pull-out part used for unlocking does not require radial deformation along the optical axis; that is, it does not need to displace perpendicular to the first direction. Instead, it only requires the action of the first and second guide members to move the pull-out part along the first direction, allowing the guide bevel to guide the movable connecting post away from the positioning groove. Therefore, neither the main body nor the pull-out part needs to have deformable parts in the radial direction along the optical axis, reducing the size of the large elastic clips found in existing LC-type fiber optic connectors and decreasing the connector's radial dimension.

[0006] Based on the first aspect, in one possible implementation, the first guide member has a first stop surface, the second guide member has a second stop surface, and the first stop surface and the second stop surface contact each other to restrict the pull-out portion from moving away from the main body portion in a second direction, the second direction being perpendicular to the first direction.

[0007] In this possible implementation, the cooperation of the first and second stop surfaces allows the pull-out portion to always remain close to the main body and move as parallel to the first direction as possible, resulting in a stronger overall integrity of the connector. It eliminates the need to press the connector and adapter together in a direction perpendicular to the first direction when assembling them.

[0008] Based on the first aspect, in one possible implementation, the first guide member includes a dovetail rail, and the second guide member includes a dovetail groove. The side of the dovetail rail facing the housing forms the first stop surface.

[0009] In this possible implementation, the cooperation between the dovetail guide rail and the dovetail groove gives the pull-out part and the main body a high connection strength. The dovetail groove and the dovetail guide rail are relatively easy to process and the processing accuracy is easy to control. Even when the connector has a small size, a high yield can still be maintained.

[0010] Based on the first aspect, in one possible implementation, the positioning groove has an opening. The housing also has a first guide surface for guiding the movable connecting post to move toward the opening, so that the movable connecting post enters the positioning groove.

[0011] In this possible implementation, when the movable connecting post has a second directional tendency to enter the positioning slot, before docking with the positioning slot, the movable connecting post needs to be moved to the open position in the opposite direction of the second direction. When the connector moves parallel to the first direction relative to the adapter, the movable connecting post can be automatically guided to the open position by the first guide surface, eliminating the need for external equipment assistance and making docking between the connector and the adapter more convenient.

[0012] Based on the first aspect, in one possible implementation, the positioning groove has an opening. The pull-out member also has a second guide surface for guiding the movable connecting post to move toward the opening, so that the movable connecting post enters the positioning groove and the guide groove.

[0013] In this possible implementation, the second guide surface can cooperate with the first guide surface to guide the movable connecting column towards the opening. The combined guidance of the second and first guide surfaces can improve the movement stability of the movable connecting column. Alternatively, if the housing does not have a first guide surface, the movable connecting column can be guided towards the opening solely by the second guide surface.

[0014] Based on the first aspect, in one possible implementation, the connector further includes a pull-out reset member. One end of the pull-out reset member acts on the main body, and the other end acts on the pull-out portion. The pull-out reset member is used to provide a reset force parallel to the first direction to the pull-out portion, and the reset force causes the guide ramp to move to the first position.

[0015] In this possible implementation, after the operator actively drives the pull-out part to move parallel to the main body in a first direction, causing the guide ramp to move from the first position to the second position, the pull-out part can be actively reset by the pull-out reset component, so that the guide ramp returns to the first position, waiting for the next connection between the connector and the adapter.

[0016] Based on the first aspect, in one possible implementation, the third stop surface is used to contact the pull-out portion to stop the pull-out member from displacing relative to the main body portion along the first direction.

[0017] In this possible implementation, the connector acts on the pull-out portion via a third stop surface, limiting the relative displacement of the pull-out portion relative to the main body portion and preventing the second guide member from disengaging from the first guide member along the first direction. Furthermore, the third stop surface can limit the extreme position of the pull-out portion relative to the main body portion in the first direction, where the relative position of the guide ramp and the movable connecting post is determined.

[0018] Based on the first aspect, in one possible implementation, the pull-out portion includes a protrusion, which is fixedly connected to the pull-out member. Along the first direction, a second guide member is disposed on one side of the protrusion, and the pull-out reset member is disposed on the other side of the protrusion. The first guide member engages with the second guide member from the side of the second guide member away from the protrusion.

[0019] In this possible implementation, the second guide and the pull-out reset member are positioned on opposite sides of the protrusion, with the port where the second guide mates with the first guide member located at the end of the second guide member furthest from the protrusion. This ensures that when the second and first guide members move, the first guide member does not significantly affect the pull-out reset member. Furthermore, when the pull-out reset member is clamped by the protrusion and the housing, the pull-out reset member restricts the displacement of the pull-out portion relative to the main body in the opposite direction of the first direction, preventing the second guide member from disengaging from the first guide member in the opposite direction of the first direction.

[0020] Based on the first aspect, in one possible implementation, the housing includes a first housing and a second housing. The first housing and the second housing are detachably connected, and the mounting cavity is formed between the first housing and the second housing.

[0021] In this possible implementation, the split design of the housing makes it easier to install and maintain the insert inside the mounting cavity.

[0022] Based on the first aspect, in one possible implementation, the first guide member is fixedly connected to the first housing. The first housing includes a mounting block that clamps the pull-out reset member in the first direction along with the pull-out portion. The first housing and the second housing move relative to each other along the first direction to connect or separate.

[0023] In this possible implementation, the first guide and the mounting block are respectively disposed on the two parts of the housing, and the first and second housings are connected by relative movement along the first direction. This allows the first and second guides to engage simultaneously during the connection process, as well as the mounting block and the pull-out portion clamping the pull-out reset component. Furthermore, although the installation direction of the pull-out reset component conflicts somewhat with the engagement direction of the first and second guides, the separate design of the first and second housings allows the first housing to move parallel to the first direction towards the second housing while engaging the first and second guides, and the second housing to move parallel to the first direction towards the first housing while compressing the pull-out reset component. When the first and second housings are connected, the engagement of the first and second guides is maintained, ensuring the first guide is at its limit position contacting the third stop surface, while the pull-out reset component is under compression. Therefore, by assembling the first and second housings simultaneously, the installation of the pull-out reset component and the engagement of the first and second guides are achieved, reducing the assembly difficulty of the pull-out portion and the main body.

[0024] A second aspect of this application provides a connector including an adapter and a connector head as described in any implementation of the first aspect. The adapter includes a housing and a connecting assembly. The housing has an insertion cavity into which the connector head is partially inserted along a first direction. The connecting assembly includes a connecting post reset member and a movable connecting post. One end of the connecting post reset member acts on the housing, and the other end acts on the movable connecting post, for driving the movable connecting post into the positioning groove.

[0025] In this connector, the connector head and adapter are combined through relative movement along a first direction. The locating groove of the connector head engages with the movable connecting post of the adapter, achieving locking of the connector head and adapter in the first direction. A connecting post reset component causes the movable connecting post to tend to move perpendicular to the first direction and toward the locating groove. After the movable connecting post enters the locating groove, the connecting post reset component can maintain the position of the movable connecting post, thus maintaining the locking of the connector head and adapter in the first direction.

[0026] Based on the second aspect, in one possible implementation, the connecting post reset member includes a first compression spring. The housing is provided with a mounting hole, and the movable connecting post includes a square segment and a cylindrical segment fixedly connected, the square segment being disposed within the mounting hole. One end of the first compression spring acts on the inner wall of the mounting hole, and the other end acts on the square segment. The cylindrical segment extends into the insertion cavity for engaging with the positioning groove.

[0027] In this connector, the movement of the movable connecting post is controlled by a first compression spring. Since the direction of the spring's elastic force is relatively fixed, this reset element can drive the movable connecting post with a relatively defined movement trajectory, allowing it to move along the length of the first compression spring. Furthermore, the outer contour of the square segment of the movable connecting post has a planar surface, making it easier for the first compression spring to apply force to the post. The cylindrical segment of the movable connecting post can better cooperate with the guide ramp, enabling the guide ramp to drive the movement of the movable connecting post.

[0028] Based on the second aspect, in one possible implementation, the block segment has two receiving slots on both sides of the first direction. There are two first compression springs, each corresponding to one of the receiving slots, with a portion of the first compression spring housed within the receiving slot.

[0029] The connector has two receiving slots on the square segment, which can compress the volume of the square segment, making it easier to install the first compression spring. In addition, the two receiving slots can also guide the deformation of the first compression spring, so that the first compression spring provides a directionally stable elastic force.

[0088] In the following detailed description of the embodiments in conjunction with the schematic diagrams, for ease of explanation, the diagrams showing the partial structure of the device will be enlarged locally without adhering to the usual scale, and the schematic diagrams are merely examples and should not limit the scope of protection of this application.

[0089] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0090] Figure 1A first-view structural schematic diagram of the connector 001 in the first embodiment of this application is shown. Figure 2 An exploded view of connector 001 in the first embodiment of this application is shown.

[0091] like Figure 1 As shown, the connector 001 includes a connector head 010 and an adapter 030. The end of the connector head 010 along the first direction X is inserted into the adapter 030. Optionally, the connector head 010 is connected to an optical fiber cable 050, and the connection between the optical fiber cable 050 and the adapter 030 is achieved through the mating of the connector head 010 and the adapter 030.

[0092] like Figure 2 As shown, the adapter 030 includes a housing 100 and a connecting assembly 200. The housing 100 has an insertion cavity 101, and the end of the connector 010 extending in the first direction X extends into the insertion cavity 101. The housing 100 has a mounting hole 110 at its end in the second direction Y, and the connecting assembly 200 is partially accommodated in the mounting hole 110, thereby enabling the connecting assembly 200 to assemble and engage with the housing 100.

[0093] Please refer to the following: Figure 1 and Figure 2 The mounting assembly includes a movable connecting post 210 and a connecting post reset component 230. The movable connecting post 210 includes a block segment 211 and a cylindrical segment 213. The block segment 211 is housed within a mounting hole 110, and the cylindrical segment 213 extends from one end of the block segment 211 parallel to the second direction Y into the insertion cavity 101. A limiting plate 111 is provided within the mounting hole 110. The limiting plate 111 is integrally formed with the outer shell 100, and the contact and engagement between the block segment 211 and the limiting plate 111 restricts the movement of the block segment 211 towards the insertion cavity 101. Through the engagement of the limiting plate 111 and the block segment 211, the relative position of the outer shell 100 and the movable connecting post 210 in the second direction Y is restricted.

[0094] The connecting post reset component 230 includes two first compression springs 231. A receiving groove 2111 is provided on each side of the block segment 211 in the first direction X, with each receiving groove 2111 corresponding to one first compression spring 231. A deformation cavity is formed between the receiving groove 2111 and the inner wall of the mounting hole 110. The first compression spring 231 is disposed within the deformation cavity, with one end acting on the inner wall of the receiving groove 2111 and the other end acting on the inner wall of the mounting hole 110. The first compression spring 231 provides elastic force, causing the movable connecting post 210 to tend to move away from the first compression spring 231; that is, the first compression spring 231 can drive the movable connecting post 210 to move parallel to the second direction Y.

[0095] The connector 010 includes a main body 300 and a pull-out part 400.

[0096] Figure 3 A second-view structural schematic diagram of the connector 001 in the first embodiment of this application is shown. Figure 4 It shows Figure 3 Sectional view along the AA direction.

[0097] Please refer to the following: Figure 3 and Figure 4 The main body 300 includes a housing 310, within which a mounting cavity 311 is formed. The mounting cavity 311 accommodates a ferrule 011, which is fixedly connected to an optical fiber cable 050. The ferrule 011 engages with an adapter 030 to connect the optical fiber cable 050 to the adapter 030. A positioning groove 3131 is provided at one end of the housing 310 in the second direction Y, extending in the third direction Z. When the connector 010 extends into the insertion cavity 101 in the first direction X, the movable connecting post 210 is inserted into the positioning groove 3131. The contact engagement between the outer wall of the movable connecting post 210 and the inner wall of the positioning groove 3131 restricts the movement of the main body 300 relative to the adapter 030 in the first direction X.

[0098] The pull-out section 400 includes a pull-out member 410 extending along a first direction X. A guide groove 411 is provided on the pull-out member 410, and the inner wall of the guide groove 411 forms a guide slope 4111. When the movable connecting post 210 extends into the positioning groove 3131, the movable connecting post 210 also extends into the guide groove 411. A gripping block 417 is provided at the end of the pull-out member 410 away from the adapter 030, which facilitates gripping by the operator to apply force to the pull-out member 410. When the movable connecting post 210 extends into the guide groove 411, by pulling the pull-out member 410 in the opposite direction of the first direction X, the guide slope 4111 is driven to move from a first position to a second position, thus causing the guide slope 4111 to act on the movable connecting post 210. The first position and the second position are the positions of the guide slope 4111 relative to the main body 300. Driven by the guide ramp 4111, the movable connecting post 210 moves parallel to the third direction Z and disengages from the positioning groove 3131 from the opening of the positioning groove 3131. At this time, the positions of the main body 300 and the adapter 030 in the first direction X are unlocked, and the main body 300 can be pulled out from the insertion cavity 101.

[0099] The main body 300 also includes a first guide member 330, which is fixedly connected to the housing 310. The pull-out part 400 also includes a second guide member 430, which is fixedly connected to the pull-out part 410. The first guide member 330 and the second guide member 430 are slidably engaged along a first direction X. Through the guidance of the first guide member 330 and the second guide member 430, the relative movement direction of the pull-out part 410 and the housing 310 is restricted, so that when the pull-out part 410 is subjected to force, it moves as parallel as possible to the first direction X relative to the housing 310.

[0100] Figure 5 A schematic diagram of the pull-out member 410 in the first embodiment of this application is shown.

[0101] Please refer to the following: Figure 4 and Figure 5 Optionally, the first guide member 330 includes a dovetail guide rail, and the second guide member 430 includes a dovetail groove. The dovetail guide rail extends along a first direction X, and the dovetail groove also extends along the first direction X. The cooperation of the dovetail guide rail and the dovetail groove restricts the relative movement of the pull-out part 400 and the main body part 300 in the third direction Z.

[0102] The dovetail guide rail also has a first stop surface 331, which is disposed facing the housing 310. The dovetail groove has a second stop surface 431. When the first stop surface 331 and the second stop surface 431 cooperate, they can restrict the pull-out part 400 from moving away from the main body part 300 in the second direction Y.

[0103] Understandably, the first guide member 330 and the second guide member 430 can also be configured such that the first guide member 330 includes a dovetail groove and the second guide member 430 includes a dovetail guide rail.

[0104] Understandably, the first guide member 330 and the second guide member 430 can also adopt other matching forms, such as the second guide member 430 being set as a T-slot and the first guide member 330 being set as a T-shaped guide rail corresponding to the T-slot.

[0105] Understandably, the resetting component 230 of the connecting column may not be the first compression spring 231. For example, it may be an elastic component such as a spring sheet or an elastic washer that can drive the movable connecting column 210 to move linearly, or it may be an elastic component such as a torsion spring that can drive the movable connecting column 210 to rotate relative to the outer shell 100.

[0106] Please return to the reference. Figure 2The housing 310 also has a first guide surface 3133. Specifically, the housing 310 includes a first boss 313, a positioning groove 3131 formed in the first boss 313, and a first guide surface 3133 formed at the end of the first boss 313 located in the first direction X. The first guide surface 3133 is inclined relative to the first direction X. When the main body 300 extends into the insertion cavity 101 along the first direction X, the first guide surface 3133 first contacts the movable connecting post 210. As the main body 300 moves further along the first direction X relative to the adapter 030, the first guide surface 3133 guides the movable connecting post 210 to move parallel to the third direction Z. At this time, the connecting post reset member 230 is compressed, and the movable connecting post 210 is guided towards the opening of the positioning groove 3131. As the movable connecting post 210 aligns with the positioning groove 3131 in the first direction X, the movable connecting post 210 disengages from the first guide surface 3133. The connecting post reset member 230 releases its elastic potential energy, driving the movable connecting post 210 into the positioning groove 3131, thereby achieving the cooperation between the movable connecting post 210 and the main body 300, and limiting the relative position of the adapter 030 and the connector 010 in the first direction X.

[0107] The pull-out component 410 has a second guide surface 4101. The second guide surface 4101 is located at the end of the pull-out component 410 in the first direction X, and the second guide surface 4101 is inclined to the first direction X. When the pull-out component 410 moves relative to the adapter 030 in the first direction X, the movable connecting post 210 will first contact the second guide surface 4101. The second guide surface 4101 guides the movable connecting post 210 to move in the second direction Y, thereby driving the movable connecting post 210 to enter the positioning groove 3131 from the opening of the positioning groove 3131. Since the guide groove 411 partially overlaps with the positioning groove 3131, when the movable connecting post 210 enters the positioning groove 3131 from the opening of the positioning groove 3131, it also enters the guide groove 411 from the opening of the guide groove 411.

[0108] Furthermore, the pull-out component 410 forms a notch at the location where the second guide surface 4101 is set, so that the first guide surface 3133 is exposed, thus preventing the pull-out component 410 from blocking the first guide surface 3133 and affecting the fit between the first guide surface 3133 and the movable connecting post 210.

[0109] Understandably, with the first guide surface 3133 provided, the pull-out member 410 does not need to have a second guide surface 4101, as long as the pull-out member 410 does not obstruct the first guide surface 3133, allowing the first guide surface 3133 to engage with the movable connecting post 210 to guide the movable connecting post 210 to move towards the opening of the positioning groove 3131. Similarly, with the second guide surface 4101 provided, the housing 310 does not need to have a first guide surface 3133. When the connector 010 is inserted into the insertion cavity 101, the pull-out part 400 and the main body 300 are driven to move together, allowing the second guide surface 4101 to engage with the movable connecting post 210 to guide the movable connecting post 210 to move towards the opening of the positioning groove 3131.

[0110] Figure 6 An exploded view of the connector 010 in the first embodiment of this application is shown.

[0111] Please refer to the following: Figure 4 and Figure 6 The connector 010 also includes a pull-out reset member 500. The pull-out reset member 500 includes a second compression spring 510, which extends along a first direction X. One end of the second compression spring 510 acts on the main body 300, and the other end acts on the pull-out portion 400. The second compression spring 510 provides a reset force parallel to the first direction X to the pull-out portion 400. This reset force can cause the pull-out portion 400 to tend to move the guide inclined surface 4111 towards a first position. That is, the reset force can drive the pull-out portion 400 to move to the position where the guide groove 411 and the positioning groove 3131 coincide. When the connector 010 is engaged with the adapter 030, this driving force can drive the second guide surface to engage with the movable connecting post 210, thereby allowing the movable connecting post 210 to extend into the guide groove 411. Furthermore, it can stabilize the relative position of the pull-out part 400 and the movable connecting post 210, so that when the connector 001 is in use, even if the pull-out part 400 encounters a small pulling force, it can be offset by the deformation of the second compression spring 510, preventing the pull-out part 400 from moving excessively and causing the movable connecting post 210 to leave the positioning groove 3131 by the guide slope 4111. When the connector 010 and the adapter 030 do not cooperate, the second compression spring 510 can make the pull-out part 400 and the main body 300 have a relatively stable relative position, preventing the pull-out part 400 from frequently sliding on the surface of the main body 300.

[0112] Please refer to the following: Figure 5 and Figure 6The pull-out component 410 includes a second boss 415, and a second guide 430 (dovetail groove) is disposed within the second boss 415. The second boss 415 is also provided with a guide groove 4151, and a second compression spring 510 is disposed within the guide groove 4151. The guide groove 4151 extends along a first direction X, restricting the deformation of the second compression spring 510 along the first direction X. A protrusion 4153 is formed at the portion of the second boss 415 located between the second guide 430 and the guide groove 4151, and the first guide 330 (dovetail guide rail) and the second compression spring 510 are separated by the protrusion 4153.

[0113] A mounting block 315 is provided on the housing 310, and the mounting block 315 and the protrusion 4153 together clamp the second compression spring 510. By restricting the second compression spring 510 by the mounting block 315, the movement of the pull-out part 400 relative to the main body part 300 in the opposite direction of the second direction Y can be further restricted, and the excessive movement of the pull-out part 400 relative to the main body part 300 can be prevented from causing the first guide member 330 and the second guide member 430 to disengage.

[0114] The side of the first boss 313 facing the second boss 415 forms a third stop surface 3135. When the pull-out part 400 moves relative to the main body part 300 along the first direction X, the second boss 415 approaches the first boss 313. When the second boss 415 contacts the third stop surface 3135, the third stop surface 3135 stops the further movement of the pull-out part 400. When the second boss 415 contacts the third stop surface 3135, the guide groove 411 and the positioning groove 3131 coincide, and the guide groove 411 and the positioning groove 3131 can jointly accommodate the movable connecting post 210.

[0115] The housing 310 includes a first housing 317 and a second housing 319. The first housing 317 has a locking hole 3171 at its end facing the second housing 319, and the second housing 319 has a latch 3191 at its end facing the first housing 317. When the first housing 317 and the second housing 319 approach each other along a first direction X, the latch 3191 inserts into the locking hole 3171 to connect the first housing 317 and the second housing 319. A mounting cavity 311 is formed between the first housing 317 and the second housing 319, allowing for easy placement of the ferrule 011 within the mounting cavity 311 and connection of the ferrule 011 and the fiber optic cable 050 within the mounting cavity 311, protecting the connection position of the ferrule 011 and the fiber optic cable 050. An elastic element can be installed within the mounting cavity 311, acting on both the ferrule 011 and the housing 310. When connector 010 engages with adapter 030, the elastic element drives insert 011 to move toward the insertion cavity 101, ensuring that insert 011 and adapter 030 are properly connected.

[0116] The first guide member 330 is fixed to the first housing 317, and the first guide member 330 is located on the side of the first boss 313 near the second housing 319. The mounting block 315 is fixed to the second housing 319.

[0117] When assembling the pull-out part 400, the first shell 317, and the second shell 319, the assembly can be achieved as follows: the second compression spring 510 is first placed in the guide groove 4151; the first shell 317 is driven to move relative to the pull-out part 400 in a direction parallel to the first direction X, so that the first guide member 330 and the second guide member 430 achieve guiding engagement; the second shell 319 is driven to move relative to the pull-out part 400 in a direction parallel to the first direction X, so that the mounting block 315 contacts the second compression spring 510 and compresses the second compression spring 510, and so that the buckle 3191 of the second shell 319 enters the buckle hole 3171.

[0118] The housing 310 is configured as a detachable first housing 317 and a second housing 319. The first guide 330, which cooperates with the second guide 430, and the mounting block 315, which cooperates with the second compression spring 510, are respectively disposed on the first housing 317 and the second housing 319, which facilitates the assembly of the housing 310 and the pull-out part 400, and allows the first guide 330, the second guide 430, and the second compression spring 510 to be assembled simultaneously.

[0119] When this connector 001 connects the connector head 010 and the adapter 030, the operator drives the connector head 010 to extend into the insertion cavity 101 along the first direction X. Inside the insertion cavity 101, the first guide surface 3133 first contacts the first guide surface 3133, which drives the movable connecting post 210 to move parallel to the second direction Y, causing the movable connecting post 210 to approach the opening of the positioning groove 3131. At this time, the connecting post reset member 230 is compressed and stores elastic potential energy. When the main body 300 of the connector head 010 moves along the first direction X, causing the movable connecting post 210 to disengage from the first guide surface and be at the opening of the positioning groove 3131, the elastic potential energy of the connecting post reset member 230 is released, causing the movable connecting post 210 to move into the positioning groove 3131. The contact between the movable connecting post 210 and the inner wall of the positioning groove 3131 restricts the relative position of the main body 300 and the adapter 030 in the first direction X. During the above process, the main body 300 and the pull-out part 400 move synchronously in the first direction X, and the connecting column also enters the guide groove 411 of the pull-out part 400 under the guidance of the second guide surface 4101.

[0120] When the connector 001 separates the connector head 010 and the adapter 030, the pull-out portion 400 is pulled. Guided by the first and second guides, the pull-out portion 400 moves relative to the main body 300 in the opposite direction to the first direction X. The guide ramp 4111 contacts the movable connecting post 210, and the guide ramp 4111 drives the movable connecting post 210 to move parallel to the second direction Y, causing the movable connecting post 210 to move toward the opening of the positioning groove 3131. At this time, a force away from the adapter 030 is continuously applied to the main body 300. When the movable connecting post 210 moves to the opening position, the engagement between the movable connecting post 210 and the positioning groove 3131 is released, and the main body 300 and the adapter 030 can move relative to each other in the first direction X again. Since the compression of the second compression spring 510 is limited, the amount of movement of the pull-out part 400 relative to the main body part 300 in the opposite direction to the first direction X is limited. On the one hand, it can prevent the first guide and the second guide from disengaging. On the other hand, it can prevent the pull-out part 400 from moving too much, causing the pull-out part 400 to be pulled out instantly. The movable connecting post 210 quickly moves from engaging with the guide inclined surface 4111 to engaging with the second guide surface 4101 again, and re-enters the positioning groove 3131.

[0121] Understandably, the pull-out part 400 may not have a guide groove 411. The guide slope 4111 is provided at the end of the pull-out part 410 located in the first direction X. When the connector 010 and the adapter 030 are engaged, the guide slope 4111 is located on the side of the movable connecting post 210 away from the first guide surface 3133. When it is necessary to separate the connector 010 and the adapter 030, the pull-out part 400 is driven to move along the first direction X, that is, driven to move towards the insertion cavity 101, so that the guide slope 4111 pushes against the movable connecting post 210 and drives the movable connecting post 210 to move towards the opening of the positioning groove 3131.

[0122] In this connector 001, the connector head 010 and adapter 030 can also be detachably coupled, and when the connector head 010 and adapter 030 are engaged, they have high connection strength. Unlocking the connector head 010 and adapter 030 is achieved by moving the pull-out portion 400 parallel to the first direction X (parallel to the optical axis), eliminating the need for deformable parts perpendicular to the first direction X in the connector head 010 and adapter 030, thus reducing their size in the first direction X. This connector 001 improves space utilization and is beneficial for fiber optic splicing in confined spaces.

[0123] Figure 7 A schematic diagram of the connector 001 in the second embodiment of this application is shown.

[0124] like Figure 7As shown, it can be understood that the adapter 030 may include two sets of connection components 200. The two sets of connection components 200 are used to connect with two connectors 010. The two connectors 010 can engage with the adapter 030 from both ends of the housing 100 in the first direction X. The connection components 200 engage with the connectors 010 one by one, so that when the connectors 010 are connected to the adapter 030, the relative positions of the connectors 010 and the adapter 030 in the first direction X are fixed.

[0125] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of disclosure of this application.
