Description

Technical Field

[0001] This invention relates to the field of fiber optic connector disassembly tools, and particularly to a shell disassembly and spring compression tool for MMC connectors. Background Technology

[0002] MMC connectors (Multi-fiber Mini Connectors) are a high-density multi-core fiber optic connection solution widely used in high-speed optical communication networks. Their housing consists of a front shell and a rear shell (including the rear shell body and tail sleeve). Inside the housing are springs and ferrules. The ferrules have pins, also called guide pins, positioning pins, or guide pins, used to improve positioning accuracy and ensure precise alignment of the two ferrules. The spring abuts against the rear shell and the ferrule, causing the ferrule to extend from one end of the front shell. During production assembly, performance testing, and field maintenance, it is often necessary to open the connector housing and separate the internal pins from the ferrules for inspection, replacement, or adjustment. When removing the pins, the spring must be separated from the ferrule to release the axial preload and mechanical restraint of the spring on the ferrule and pins, allowing the pins to be removed safely and without damage.

[0003] Currently, some simple connector disassembly tools exist on the market, but they are usually single-function or require multiple tools to work together, making the disassembly process cumbersome, time-consuming, inconvenient, and inefficient. Furthermore, they cannot stably secure the connector when the spring is compressed, requiring the operator to manually maintain clamping force. This poses a risk of pins popping out and causing injury, or damaging the internal ferrule, pins, and spring mechanism, easily leading to product scrap. In addition, standardized operations are not possible; general-purpose tools rely on operator experience and feel, resulting in inconsistent disassembly quality and affecting product reliability and yield.

[0004] Therefore, there is an urgent need for a dedicated disassembly tool that is easy to operate and can protect the device, designed specifically for the structural characteristics of MMC connectors. Summary of the Invention

[0005] The main objective of this invention is to provide a shell disassembly and spring compression tool for MMC connectors, which aims to solve the problems of inconvenience, low efficiency, easy damage to components, and inability to perform standardized operations when using existing general tools or purely manual disassembly of MMC connectors.

[0006] To achieve the above objectives, the MMC connector housing disassembly and spring compression tool proposed in this invention has a disassembly portion and a spring compression portion. The disassembly portion has a disassembly groove, one end of which has an insertion port for inserting the MMC connector into the disassembly groove. The disassembly portion also has a disassembly protrusion extending into the disassembly groove, which abuts against the front shell of the MMC connector to disengage it from the rear shell. The spring compression portion includes a first clamping arm and a second clamping arm, and a clamping channel for accommodating the MMC connector is formed between the first clamping arm and the second clamping arm. The first clamping arm and the second clamping arm are configured to move away from each other under external force to expand the clamping channel. One end of the clamping channel has a stop protrusion extending into the clamping channel, which compresses the spring. The first clamping arm and the second clamping arm clamp the rear shell of the MMC connector so that the spring compression portion remains stationary relative to the rear shell of the MMC connector.

[0007] In one embodiment, the MMC connector housing disassembly and spring compression tool includes a first rotating part and a second rotating part. The first rotating part has the disassembly portion and the first clamping arm at its two ends, and the first rotating part also has a hinge shaft. The second rotating part has a hinge hole and the second clamping arm at its opposite ends, and the hinge shaft is hinged to the hinge hole.

[0008] In one embodiment, the disassembly portion and the first clamping arm are located on opposite sides of the hinge shaft.

[0009] In one embodiment, a first elastic buckle is provided at the end of the hinge shaft away from the first rotating member. The first elastic buckle includes a first cantilever and a first snap-fit ​​protrusion. The fixed end of the first cantilever is connected to the hinge shaft, and the first snap-fit ​​protrusion is provided at the free end of the first cantilever. A limiting boss is provided on the inner wall of the hinge hole, and the first snap-fit ​​protrusion is elastically snapped into the side of the limiting boss facing away from the first rotating member.

[0010] In one embodiment, the first clamping arm is provided with a first locking part, and the second clamping arm is provided with a second locking part; the first locking part and the second locking part have a locked state and an unlocked state, wherein in the locked state, the first locking part and the second locking part are connected, and in the unlocked state, the first locking part and the second locking part are separated.

[0011] In one embodiment, one of the first locking part and the second locking part is a second elastic buckle, and the other is a snap-fit ​​hole; the second elastic buckle passes through the snap-fit ​​hole and elastically snaps into the periphery of the snap-fit ​​hole.

[0012] In one embodiment, the first or second clamping arm is provided with a clamping protrusion, and the rear shell of the MMC connector is provided with a clamping groove. The clamping protrusion is used to abut against the inner wall of the clamping groove so that the spring compression portion is stationary relative to the rear shell of the MMC connector, and the clamping protrusion is configured to slide along the clamping groove when subjected to an external force.

[0013] In one embodiment, a first elastic arm is formed on the first clamping arm, and a second elastic arm is formed on the second clamping arm; a clamping protrusion is formed on the first elastic arm and the second elastic arm respectively, and a clamping groove is provided on each opposite side of the rear shell of the MMC connector, with each clamping protrusion corresponding to a clamping groove.

[0014] In one embodiment, the disassembly protrusion has a guide surface on the side facing the insertion port, the guide surface being used to slide with the housing of the MMC connector, and an abutment surface is formed on the side of the disassembly protrusion facing away from the insertion port, the abutment surface being used to abut against the front housing of the MMC connector; and / or, the disassembly portion has at least two of the disassembly protrusions.

[0015] In one embodiment, a stepped portion is provided at one end of the disassembly groove away from the insertion port, the stepped portion being used to abut against the housing of the MMC connector.

[0016] The MMC connector housing disassembly and spring compression tool proposed in this invention allows for the following steps: When disassembling the MMC connector housing, the MMC connector is inserted into the disassembly slot through the insertion port. After insertion, the disassembly protrusion abuts against the front housing of the MMC connector. The MMC connector can then be pulled out in reverse, and the front and rear housings separate under the pulling force, exposing the ferrule and spring. When removing the PIN pin, the MMC connector with the front housing removed is placed between the first and second clamping arms, with the stop protrusion aligned with the end of the spring closest to the ferrule. The MMC connector is then pushed, causing the stop protrusion to compress the spring until it separates from the ferrule and PIN pin. During this pushing process, the pushing force overcomes the frictional force generated by the first and second clamping arms holding the rear housing of the MMC connector, causing the MMC connector to slide relative to the first and second clamping arms. After the pushing force disappears, the frictional force generated by the first and second clamping arms holding the rear housing of the MMC connector is greater than or equal to the spring force, keeping the MMC connector stationary relative to the first and second clamping arms. Thus, the spring remains detached from the ferrule and PIN pin. The MMC connector housing removal and spring compression tool of this invention enables the removal of the MMC connector housing and the compression of the spring to pull out the PIN pins. Compared with the traditional method of disassembly by operators using general tools or purely manual methods, it is more convenient and faster, and can avoid errors or damage to the device caused by improper operation. Furthermore, it does not require multiple tools and does not rely on the operator's experience and feel, thus achieving standardized operation. Attached Figure Description

[0024] This invention proposes a housing disassembly and spring compression tool 1000 for MMC connectors.

[0025] like Figure 1 As shown, the outer shell 2100 of the MMC connector 2000 is composed of a front shell 2110 and a rear shell 2120 (including the rear shell body 2121 and the tail sleeve 2122). The outer shell 2100 contains a spring 2400 and a ferrule 2200. The ferrule 2200 has a PIN pin 2300, also known as a guide pin, positioning pin, or guide pin, used to improve positioning accuracy and ensure precise alignment of the two ferrules 2200. The spring 2400 abuts against the rear shell 2120 and the ferrule 2200, causing the ferrule 2200 to extend from one end of the front shell 2110. During production assembly, performance testing, and field maintenance, it is often necessary to open the connector's outer shell 2100 and separate the internal PIN pin 2300 from the ferrule 2200 for inspection, replacement, or adjustment. When removing the PIN pin 2300, the spring 2400 needs to be separated from the insert 2200 to release the axial preload and mechanical restraint of the spring 2400 on the insert 2200 and the PIN pin 2300, so that the PIN pin 2300 can be removed safely and without damage.

[0026] Please see Figures 2 to 6In one embodiment of the present invention, the MMC connector housing disassembly and spring compression tool 1000 has a disassembly portion 11 and a spring compression portion formed thereon; the disassembly portion 11 has a disassembly groove 11a, one end of which has an insertion port 11b for inserting the MMC connector 2000 into the disassembly groove 11a; the disassembly portion 11 also has a disassembly protrusion 111 extending into the disassembly groove 11a, the disassembly protrusion 111 for abutting against the front shell 2110 of the MMC connector 2000 to disengage from the rear shell 2120 of the MMC connector 2000; the spring compression portion includes a first clamping arm 12 and The second clamping arm 21 and the first clamping arm 12 form a clamping channel 1000a for accommodating the MMC connector 2000. The first clamping arm 12 and the second clamping arm 21 are configured to move away from each other under external force so that the clamping channel 1000a expands. A stop protrusion 3 extending into the clamping channel 1000a is formed at one end of the clamping channel 1000a. The stop protrusion 3 is used to compress the spring 2400. The first clamping arm 12 and the second clamping arm 21 are used to clamp the rear shell 2120 of the MMC connector 2000 so that the spring compression part is stationary relative to the rear shell 2120 of the MMC connector 2000.

[0027] In this embodiment, the disassembly part 11 provides an insertion space for the MMC connector 2000 and achieves separation of the front shell 2110 and the rear shell 2120 through mechanical abutment. Specifically, the disassembly part 11 forms a disassembly groove 11a, which provides a receiving space for the MMC connector 2000, and an insertion port 11b formed at one end allows the MMC connector 2000 to enter the interior of the disassembly groove 11a. A disassembly protrusion 111 extending into the disassembly groove 11a is formed on the inner sidewall of the disassembly groove 11a, and this disassembly protrusion 111 forms an abutment relationship with the front shell 2110 after the MMC connector 2000 is inserted. Figure 1 As shown, there is a gap 2100a between the front shell 2110 and the rear shell 2120, exposing the end face of the front shell 2110 near the rear shell 2120. The disassembly protrusion 111 can extend into this gap 2100a and abut against the end face of the front shell 2110. Figure 9 As shown, when the MMC connector 2000 is inserted into the disassembly slot 11a from the insertion port 11b, the disassembly protrusion 111 contacts the end face of the front shell 2110 near the rear shell 2120. If a reverse pulling force is applied to the MMC connector 2000 at this time, the disassembly protrusion 111 acts as a fixed fulcrum to prevent the front shell 2110 from moving backward, while the pulling force acts on the rear shell 2120, causing it to move away from the front shell 2110. Under the action of the splicing structure between the front shell 2110 and the rear shell 2120, the two are separated. The shape of the disassembly protrusion 111 can be wedge-shaped, rectangular, or other geometric shapes that can provide an effective contact surface 1112. Its material can be metal or high-strength engineering plastic to ensure sufficient structural strength during the application of force without deformation or damage.

[0028] The spring compression section is used to fix the rear shell 2120 of the MMC connector 2000 and compress the internal spring 2400. Specifically, the spring compression section includes a first clamping arm 12 and a second clamping arm 21, and a clamping channel 1000a is formed between the first clamping arm 12 and the second clamping arm 21 for accommodating the MMC connector 2000. The clamping channel 1000a provides lateral constraint space for the MMC connector 2000. The first clamping arm 12 and the second clamping arm 21 are configured to move away from each other under external force to expand the clamping channel. This relatively movable design allows the width of the clamping channel 1000a to be adjusted to facilitate the insertion and removal of the MMC connector 2000. Optionally, both the first clamping arm 12 and the second clamping arm 21 are made of elastic material and integrally formed into the MMC connector 2000. Thus, the elasticity and deformability of the first clamping arm 12 and the second clamping arm 21 themselves allow them to open when subjected to external force, expanding the clamping channel. Furthermore, the elastic material gives them a tendency to return to their original position, providing clamping force. Further, before being subjected to external force, the distance between the first clamping arm 12 and the second clamping arm 21 can be set slightly smaller than the size of the MMC connector 2000, allowing the rebound force of the first clamping arm 12 and the second clamping arm 21 to clamp the MMC connector 2000 without the need for manual application of clamping force.

[0029] One end of the clamping channel 1000a has a stop protrusion 3 extending into the clamping channel 1000a, the position of which corresponds to the end of the internal spring 2400 of the MMC connector 2000 near the ferrule 2200. For example... Figures 10 to 11 As shown, when the MMC connector 2000 is pushed to move towards the stop protrusion 3 within the clamping channel 1000a, the stop protrusion 3 can contact the end face of the spring 2400 and compress the spring 2400. At the same time, the first clamping arm 12 and the second clamping arm 21 clamp the rear shell 2120 of the MMC connector 2000. The clamping action of the two arms on the rear shell 2120 generates friction. When the pushing force is released, this friction allows the spring compression part to remain stationary relative to the rear shell 2120 of the MMC connector 2000. Meanwhile, the spring 2400 remains compressed and disengages from the ferrule 2200 and the PIN pin 2300, allowing the operator to safely remove the PIN pin 2300.

[0030] In summary, the MMC connector housing disassembly and spring compression tool 1000 of this embodiment can disassemble the housing 2100 and compression spring 2400 of the MMC connector 2000 to remove the PIN pin 2300. Compared with traditional methods where operators typically use general tools or manual methods for disassembly, this method is more convenient and faster because it eliminates the need to frequently change the angle and position of force application. Furthermore, since the force direction of the MMC connector 2000 in this embodiment is fixed, only reciprocating force along the connector axis is required when disassembling the housing 2100, and only one direction is needed to compress the spring 2400 when disassembling the PIN pin 2300. The operation is simple, and the positions of the disassembly protrusion 111, stop protrusion 3, etc., can be preset according to the MMC connector 2000, thus avoiding errors or damage to the device caused by improper operation, and preventing the PIN pin from popping out and causing injury. The MMC connector housing disassembly and spring compression tool 1000 of this embodiment does not require multiple tools and does not rely on the operator's experience and feel, achieving standardized operation.

[0031] Please see Figures 2 to 6 In one embodiment of the present invention, the MMC connector housing disassembly and spring compression tool 1000 includes a first rotating part 1 and a second rotating part 2. The two ends of the first rotating part 1 are respectively provided with a disassembly part 11 and a first clamping arm 12, and the first rotating part 1 is also provided with a hinge shaft 13. The two opposite ends of the second rotating part 2 are respectively provided with a hinge hole 2a and a second clamping arm 21, and the hinge shaft 13 is hinged to the hinge hole 2a.

[0032] In this embodiment, the MMC connector housing disassembly and spring compression tool 1000 is a split structure, including a first rotating component 1 and a second rotating component 2. The first rotating component 1 serves as the base component supporting the disassembly part 11 and the first clamping arm 12, and is rotatably connected to the second rotating component 2 via a hinge shaft 13. The material of the first rotating component 1 can be metal or high-strength engineering plastic, and its structure can be plate-shaped, block-shaped, or ergonomically designed; this embodiment does not limit this.

[0033] The second rotating member 2 serves as the base component supporting the second clamping arm 21, and together with the first rotating member 1, forms a complete spring compression section. The two opposite ends of the second rotating member 2 are respectively provided with hinge holes 2a and a second clamping arm 21. The hinge holes 2a are used for hinged connection with the hinge shaft 13 on the first rotating member 1, and the second clamping arm 21 is used to cooperate with the first clamping arm 12 to clamp the rear shell 2120 of the MMC connector 2000. When the first rotating member 1 and the second rotating member 2 rotate relative to each other, the first clamping arm 12 and the second clamping arm 21 can move closer or further apart, and the size of the clamping channel 1000a between the first clamping arm 12 and the second clamping arm 21 changes accordingly. When the first clamping arm 12 and the second clamping arm 21 approach each other, the first clamping arm 12 and the second clamping arm 21 can enclose each other to form a clamping channel 1000a with a smaller width, thereby clamping the back shell 2120 of the MMC connector 2000; when the first clamping arm 12 and the second clamping arm 21 move away from each other, the size of the clamping channel 1000a increases, making it easier to insert or remove the MMC connector 2000.

[0034] Please see Figures 2 to 6 In one embodiment of the present invention, the disassembly part 11 and the first clamping arm 12 are located on both sides of the hinge shaft 13.

[0035] In this embodiment, the first rotating member 1 has a disassembly part 11 and a first clamping arm 12 at both ends, that is, the disassembly part 11 and the first clamping arm 12 are located on both sides of the hinge shaft 13. This arrangement at both ends makes the disassembly part 11 and the spring compression part clearly separated, avoiding mutual interference and space occupation, and the disassembly part 11 and the spring compression part can work independently at the same time, improving work efficiency.

[0036] Please see Figure 5 , Figure 6 and Figure 11 In one embodiment of the present invention, a first elastic buckle 131 is provided at the end of the hinge shaft 13 away from the first rotating member 1. The first elastic buckle 131 includes a first cantilever 1311 and a first snap-fit ​​protrusion 1312. The fixed end of the first cantilever 1311 is connected to the hinge shaft 13, and the first snap-fit ​​protrusion 1312 is provided at the free end of the first cantilever 1311. A limiting boss 22 is provided on the inner wall of the hinge hole 2a. The first snap-fit ​​protrusion 1312 is elastically snapped with the side of the limiting boss 22 facing away from the first rotating member 1.

[0037] In this embodiment, three first elastic latches 131 are disposed at the end of the hinge shaft 13 away from the first rotating member 1 and arranged in a circular array. Each first elastic latch 131 includes a first cantilever 1311 and a first engaging protrusion 1312. The fixed end of the first cantilever 1311 is connected to the hinge shaft 13, and the first cantilever 1311 is an elastic structure. It should be noted that the number of elastic latches can be one, two, three, etc., and this embodiment does not limit this. The first cantilever 1311 can be a sheet-like or strip-like structure extending radially along the hinge shaft 13. Its material can be the same as the hinge shaft 13 or a material with better elasticity to ensure that it can generate elastic deformation and bend towards the center of the hinge shaft 13 when subjected to radial pressure, and can return to its original shape after the pressure is released. The first engaging protrusion 1312 is disposed at the free end of the first cantilever 1311, and the protrusion can be a wedge-shaped, hemispherical, or hook-shaped structure. The inner wall of the hinge hole 2a is provided with a limiting boss 22. This limiting boss 22 is arranged in a ring-shaped protrusion structure along the circumference of the hinge hole 2a. Alternatively, multiple spaced limiting bosses 22 can be provided in the circumference of the hinge hole 2a to ensure that at least one limiting boss 22 is always engaged with the first locking protrusion 1312 when the hinge shaft 13 rotates relative to the inner wall of the hinge hole 2a. The first locking protrusion 1312 and the limiting boss 22 are elastically engaged on the side opposite to the first rotating member 1. This engagement relationship achieves axial locking between the first rotating member 1 and the second rotating member 2. At the same time, since the first cantilever 1311 can undergo elastic deformation, it can also be unlocked under the action of external force. During the assembly process, when the hinge shaft 13 is inserted into the hinge hole 2a, the first locking protrusion 1312 is squeezed by the limiting boss 22, and the first cantilever 1311 undergoes elastic deformation and retracts towards the center of the hinge shaft 13, so that the first locking protrusion 1312 can smoothly pass over the limiting boss 22. Once the first engaging protrusion 1312 has completely passed the limiting boss 22, the first cantilever 1311 elastically recovers its original shape. The first engaging protrusion 1312 and the limiting boss 22 on the side facing away from the first rotating member 1 then abut against each other. At this point, if an attempt is made to pull the hinge shaft 13 out of the hinge hole 2a, the abutting surfaces 1112 of the first engaging protrusion 1312 and the limiting boss 22 will block each other, preventing axial separation. This elastic engaging structure ensures both ease of assembly and reliable anti-disengagement protection.

[0038] Please see Figures 3 to 5 In one embodiment of the present invention, the first clamping arm 12 is provided with a first locking part, and the second clamping arm 21 is provided with a second locking part; the first locking part and the second locking part have a locked state and an unlocked state. In the locked state, the first locking part and the second locking part are connected, and in the unlocked state, the first locking part and the second locking part are separated.

[0039] In this embodiment, based on the above-described embodiment where the hinge shaft 13 connects and engages with the hinge hole 2a, to achieve the goal of eliminating the need for continuous manual clamping force during the compression of the spring 2400, a first locking part and a second locking part are respectively provided on the first clamping arm 12 and the second clamping arm 21. This allows the spring compression part to maintain a clamping state on the rear shell 2120 without the need for continuous manual clamping force, thereby freeing the operator's hands for delicate operations such as removing the PIN needle 2300, improving the convenience and safety of the operation. Optionally, one of the first locking part and the second locking part can be a threaded hole, and the other can be a bolt. In the locked state, the bolt engages with the inner wall of the threaded hole, and in the unlocked state, the bolt disengages from the threaded hole. Preferably, one of the first locking part and the second locking part is an elastic buckle, and the other is a step or hole that engages with the elastic buckle. In the locked state, the elastic buckle engages with the periphery of the step or hole, and in the unlocked state, the elastic buckle disengages from the periphery of the step or hole.

[0040] In the locked state, even if the operator stops applying gripping force to the first rotating member 1 and the second rotating member 2, the engagement of the first locking part and the second locking part can prevent the first clamping arm 12 and the second clamping arm 21 from automatically opening under the elastic force of the spring 2400 or other external forces, thereby maintaining the clamping effect of the clamping channel 1000a on the rear shell 2120 of the MMC connector 2000, and keeping the stop protrusion 3 in the position of the compressed spring 2400. In the unlocked state, the first locking part and the second locking part separate, the engagement between them is released, the first clamping arm 12 and the second clamping arm 21 can move away from each other, the width of the clamping channel 1000a increases, and it is easier to insert or remove the MMC connector 2000.

[0041] Please see Figures 3 to 5 In one embodiment of the present invention, one of the first locking part and the second locking part is a second elastic buckle 23, and the other is a snap-fit ​​hole 12a; the second elastic buckle 23 passes through the snap-fit ​​hole 12a and is elastically snapped into the periphery of the snap-fit ​​hole 12a.

[0042] In this embodiment, one of the first locking part and the second locking part is a second elastic buckle 23, and the other is a snap-fit ​​through hole 12a. Optionally, the first snap-fit ​​part is the second elastic buckle 23, and the second snap-fit ​​part is the snap-fit ​​through hole 12a. That is, the second elastic buckle 23 is disposed on the first clamping arm 12, and the snap-fit ​​through hole 12a is disposed on the second clamping arm 21. Alternatively, the second snap-fit ​​part is the second elastic buckle 23, and the first snap-fit ​​part is the snap-fit ​​through hole 12a. That is, the second elastic buckle 23 is disposed on the second clamping arm 21, and the snap-fit ​​through hole 12a is disposed on the first clamping arm 12.

[0043] The second elastic buckle 23 may include a second cantilever 231 and a second engaging protrusion 232. The fixed end of the second cantilever 231 is fixedly connected to the first clamping arm 12 or the second clamping arm 21, and the second engaging protrusion 232 is located at the free end of the second cantilever 231. The second cantilever 231 may be a sheet-like or strip-like structure, extending in a direction perpendicular to the opposite surface of the first clamping arm 12. The second engaging protrusion 232 may be a wedge-shaped, hemispherical, or hook-shaped structure located on the outside of the second cantilever 231. The engaging through hole 12a may be square, rectangular, or other hole shapes adapted to the cross-sectional shape of the second elastic buckle 23. Its opening position is located on the second clamping arm 21 corresponding to the second elastic buckle 23, so as to ensure that the second elastic buckle 23 can be aligned with the engaging through hole 12a when the first clamping arm 12 and the second clamping arm 21 are close together.

[0044] When the first clamping arm 12 and the second clamping arm 21 approach each other, the second elastic buckle 23 aligns with and enters the locking hole 12a. The second cantilever 231 undergoes elastic deformation due to the pressure of the second locking protrusion 232 against the periphery of the locking hole 12a. Once the second locking protrusion 232 has completely passed through the locking hole 12a, the second cantilever 231 recovers its elasticity, and the second locking protrusion 232 engages with the periphery of the locking hole 12a, forming a locked state. To unlock, the operator can apply pressure to the second elastic buckle 23 to disengage the second locking protrusion 232 from the periphery of the locking hole 12a, allowing the first clamping arm 12 and the second clamping arm 21 to move away from each other, restoring the unlocked state. Thus, compared to bolt locking, this embodiment uses the second elastic buckle 23 in conjunction with the locking hole 12a to more conveniently and quickly lock and unlock the first and second locking parts. Furthermore, the snap-fit ​​hole 12a can limit and guide the second cantilever 231, effectively preventing the second cantilever 231 from deflecting or buckling during the snap-fit ​​process, thereby improving structural stability and the reliability of repeated operations.

[0045] Please see Figures 2 to 5 In one embodiment of the present invention, the first clamping arm 12 or the second clamping arm 21 is provided with a clamping protrusion 4. Please refer to [link to relevant documentation]. Figure 1 The rear housing 2120 of the MMC connector 2000 is provided with a clamping groove 2120a. The clamping protrusion 4 is used to abut against the inner wall of the clamping groove 2120a so that the spring compression part is stationary relative to the rear housing 2120 of the MMC connector 2000, and the clamping protrusion 4 is configured to slide along the clamping groove 2120a when subjected to external force.

[0046] In this embodiment, the cross-sectional shape of the clamping protrusion 4 can be adapted to the cross-sectional shape of the clamping groove 2120a, and can be rectangular, trapezoidal, semi-circular, or other shapes. The clamping protrusion 4 is integrally formed with the clamping arm, and can also be made of materials with higher hardness or better wear resistance to extend its service life. The clamping protrusion 4 can penetrate deep into the clamping groove 2120a and abut against the inner wall of the clamping groove 2120a. The clamping groove 2120a is a groove structure extending axially along the rear shell 2120 of the MMC connector 2000, and its cross-sectional shape is adapted to the clamping protrusion 4, and can be rectangular, trapezoidal, arc-shaped, or other shapes. The length of the clamping groove 2120a can cover the entire distance that the MMC connector 2000 slides from the insertion position to the fully compressed position of the spring 2400 within the clamping channel 1000a, ensuring that the clamping protrusion 4 always maintains a mating relationship with the clamping groove 2120a during the sliding process. The inner wall of the clamping groove 2120a is a flat and smooth surface, which provides a continuous and uniform sliding contact surface for the clamping protrusion 4.

[0047] The clamping protrusion 4 is configured to slide along the clamping groove 2120a when subjected to external force. For example, when an operator applies an axial thrust along the clamping channel 1000a to the MMC connector 2000 to compress the spring 2400, this thrust overcomes the frictional resistance between the clamping protrusion 4 and the inner wall of the clamping groove 2120a, causing the MMC connector 2000 to move relative to the first clamping arm 12 and the second clamping arm 21. During this process, the clamping protrusion 4 slides along the extending direction of the clamping groove 2120a. Compared to directly clamping the surface of the housing 2100 of the MMC connector 2000, the entire process of the clamping protrusion 4 sliding against the inner wall of the clamping groove 2120a is not jammed because the inner wall of the clamping groove 2120a is smooth and flat, while the surface of the housing 2100 of the MMC connector 2000 may have gaps, steps, or other uneven features, which may cause jamming and greater resistance when pushing the connector to compress the spring 2400. Furthermore, the small contact area between the clamping protrusion 4 and the inner wall of the clamping groove 2120a results in a larger pressure under the same pressure, leading to greater friction between the actual contact surfaces. When the operator removes the pushing force, the friction between the clamping protrusion 4 and the inner wall of the clamping groove 2120a more effectively prevents the MMC connector 2000 from rebounding, making the clamping more stable and ensuring that the spring 2400 can reliably remain in a compressed state. Furthermore, the clamping protrusion 4 can be gradually tapered from its root to its top to further reduce the contact area with the inner wall of the clamping groove 2120a, thereby increasing the friction.

[0048] Please see Figures 2 to 5In one embodiment of the present invention, a first elastic arm 121 is formed on the first clamping arm 12, and a second elastic arm 211 is formed on the second clamping arm 21; a clamping protrusion 4 is formed on the first elastic arm 121 and the second elastic arm 211 respectively; a clamping groove 2120a is provided on the opposite sides of the rear shell 2120 of the MMC connector 2000, and each clamping protrusion 4 is provided with a clamping groove 2120a.

[0049] In this embodiment, the first elastic arm 121 and the second elastic arm 211 provide elastic support and adaptive adjustment capability for the clamping protrusion 4. Specifically, the first elastic arm 121 can be a cantilever structure integrally formed with the first clamping arm 12, or it can be an independent elastic component mounted on the first clamping arm 12, with its fixed end connected to the first clamping arm 12 and its free end provided with the clamping protrusion 4. The first elastic arm 121 can be made of a thin metal sheet or an engineering plastic sheet with good elasticity. Similarly, the second elastic arm 211 can be a cantilever structure integrally formed with the second clamping arm 21, or it can be an independent elastic component mounted on the second clamping arm 21, with its fixed end connected to the second clamping arm 21 and its free end provided with the clamping protrusion 4. The second elastic arm 211 and the first elastic arm 121 are symmetrically arranged about the clamping channel 1000a to ensure that a balanced clamping force is applied to the rear shell 2120 of the MMC connector 2000. The rear shell 2120 of the MMC connector 2000 is provided with a clamping groove 2120a on each opposite side. Each clamping protrusion 4 is provided with a clamping groove 2120a. This can prevent deflection or warping caused by unilateral force.

[0050] The elastic characteristics of the first elastic arm 121 and the second elastic arm 211 provide adaptive adjustment capability for clamping. When the MMC connector 2000 is placed into the clamping channel 1000a, the first elastic arm 121 and the second elastic arm 211 can produce different degrees of elastic deformation according to the actual outer diameter of the rear shell 2120. This adaptive characteristic allows the same spring compression part to adapt to different specifications of MMC connectors 2000 within a certain size range, or to compensate for dimensional deviations caused by manufacturing tolerances, thereby improving the versatility of the tool and the reliability of clamping. The adaptive deformation capability of the first elastic arm 121 and the second elastic arm 211 also has a dual function of protecting the connector and optimizing operation. On the one hand, when the elastic arm is subjected to excessive clamping force, it can be buffered by deformation to prevent excessive clamping force that may be caused by rigid clamping and damage to the rear shell 2120 of the MMC connector 2000. On the other hand, the moderate elastic deformation of the elastic arm can avoid excessive frictional resistance caused by excessive clamping, so that the operator will not encounter excessive resistance when pushing the MMC connector 2000 to compress the spring 2400, ensuring smooth sliding.

[0051] Please see Figure 7 and Figure 8In one embodiment of the present invention, a guide surface 1111 is formed on the side of the disassembly protrusion 111 facing the insertion port 11b, the guide surface 1111 is used to slide with the housing 2100 of the MMC connector 2000, and an abutment surface 1112 is formed on the side of the disassembly protrusion 111 facing away from the insertion port 11b, the abutment surface 1112 is used to abut against the front housing 2110 of the MMC connector 2000; and / or, the disassembly portion 11 is formed with at least two disassembly protrusions 111.

[0052] In this embodiment, to improve the smoothness of the disassembly operation of the housing 2100, a guide surface 1111 is formed on the side of the disassembly protrusion 111 facing the insertion port 11b. The technical function of the guide surface 1111 is to provide smooth sliding guidance for the MMC connector 2000 to be inserted into the disassembly groove 11a. The guide surface 1111 can be a slope, an arc surface, or other continuously transitioning curved surface. It gradually moves away from the side wall of the disassembly groove 11a and gradually moves closer to the center of the disassembly groove 11a from the insertion port 11b towards the interior of the disassembly groove 11a, so that the housing 2100 of the MMC connector 2000 can slide smoothly into the guide surface 1111 during the insertion process, avoiding scratches or jamming caused by sharp edges. When the MMC connector 2000 is inserted into the insertion port 11b, the surface of its outer shell 2100 first contacts the guide surface 1111. Under the action of continuous thrust, the outer shell 2100 gradually penetrates into the disassembly groove 11a along the contour of the guide surface 1111 until the end face of the front shell 2110 passes the disassembly protrusion 111. At this time, pulling the MMC connector 2000 in the opposite direction can make the end face of the front shell 2110 contact the abutment surface 1112, thereby restricting the front shell 2110 in the disassembly groove 11a until the front shell 2110 is separated from the rear shell 2120. At this time, the front shell 2110 can be taken out from the groove of the disassembly groove 11a, while the rear shell 2120 and the ferrule 2200 leave the disassembly groove 11a from the insertion port 11b.

[0053] To address the issue of uneven stress on the front housing 2110 that might result from single-point contact, the disassembly section 11 has at least two disassembly protrusions 111. This arrangement aims to achieve balanced stress distribution on the front housing 2110 through multi-point contact. The two or more disassembly protrusions 111 can be arranged symmetrically about the disassembly groove 11a, forming symmetrical contact points. When the MMC connector 2000 is inserted into the disassembly groove 11a, the multiple disassembly protrusions 111 simultaneously contact different positions on the front housing 2110. Under the pull-out force, the front housing 2110 is supported by multiple contact surfaces 1112, preventing excessive local stress or bias pressure that could cause the front housing 2110 to tilt and jam due to single-point contact.

[0054] In this embodiment, the combined design of the guide surface 1111 and the abutment surface 1112 and the arrangement of the multiple disassembly protrusions 111 can be a technical solution used simultaneously, or one can be selected according to actual application requirements. Both designs can improve the performance of the disassembly operation of the housing 2100, making the disassembly process of the housing 2100 of the MMC connector 2000 more efficient and safe, and reducing the risk of device damage caused by improper operation.

[0055] Please see Figure 7 and Figure 8 In one embodiment of the present invention, a step portion 5 is provided at one end of the disassembly groove 11a away from the insertion port 11b, and the step portion 5 is used to abut against the housing 2100 of the MMC connector 2000.

[0056] In this embodiment, the stepped portion 5 is disposed at one end of the disassembly groove 11a away from the insertion port 11b. It can be used to provide axial limiting for the housing 2100 of the MMC connector 2000 and to provide an indication after the MMC connector 2000 is inserted, indicating that the front housing 2110 has passed the disassembly protrusion 111. At this time, pulling in the opposite direction can make the front housing 2110 abut against the disassembly protrusion 111.

[0057] Specifically, the stepped portion 5 can be a stepped structure that protrudes into the groove from the bottom or side wall of the disassembly groove 11a. The surface of the stepped portion 5 can be a side wall or bottom wall perpendicular to the disassembly groove 11a. The stepped portion 5 can be integrally formed with the side wall or bottom wall of the disassembly groove 11a. When the MMC connector 2000 is inserted into the disassembly groove 11a from the insertion port 11b, the surface of its housing 2100 slides along the inner wall of the disassembly groove 11a, and the front end gradually penetrates deeper. During the insertion process, the guide surface 1111 of the disassembly protrusion 111 provides sliding guidance for the housing 2100 until the housing 2100 of the MMC connector 2000 contacts the stepped portion 5. The step portion 5 acts as a physical barrier, preventing the MMC connector 2000 from moving forward further. At this point, the MMC connector 2000 reaches the predetermined insertion depth, and the end face of the front shell 2110 just passes the abutment surface 1112 of the disassembly protrusion 111. Pulling the MMC connector 2000 in the opposite direction will make the end face of the front shell 2110 contact the abutment surface 1112. The contact between the step portion 5 and the outer shell 2100 can also indicate to the operator that it has been inserted in place. Therefore, it effectively solves the problem of operational errors caused by inaccurate insertion depth, simplifies the operation requirements, and improves the ease of use, accuracy, and standardization of the operation.
