Description

Technical Field

[0001] This utility model relates to the field of disassembly and assembly tools and equipment, specifically to a photoelectric connector disassembly and assembly wrench. Background Technology

[0002] Optical connectors (such as LC, SC, FC, ST, etc.) and their mating nuts / housings are precision-structured, compact in size, and require high surface finish. During the installation, commissioning, and maintenance of fiber optic communication systems, tools are frequently needed to tighten or loosen connectors. Currently, commonly used tools include metal wrenches and plastic wrenches.

[0003] While metal wrenches can provide sufficient rigidity and torque transmission capacity, their hard metal surfaces are prone to scratching, crushing, or abrading the delicate plastic shells or metal nuts of optoelectronic connectors during operation, affecting their appearance, sealing, and service life. Furthermore, it is difficult for operators to precisely control the amount of torque applied, and excessive force can easily lead to structural damage such as stripped connector threads, broken interfaces, shattered internal ceramic ferrules, or deformed adapters.

[0004] While some plastic wrenches can provide some surface protection, the tool body is prone to excessive deformation, twisting, or even tearing when large torque is applied, making it unable to effectively transmit enough torque to complete disassembly and assembly. Furthermore, soft materials are more likely to slip on the connector surface under high loads, making it impossible to reliably clamp the connector. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a photoelectric connector disassembly and assembly wrench, which can effectively transmit the necessary torque and reliably clamp the photoelectric connector, effectively protect its surface from scratches and wear, and actively limit the maximum torque to prevent overload damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A photoelectric connector assembly / disassembly wrench includes a connecting section and force-applying sections fixedly connected to both ends of the connecting section. The connecting section and the force-applying sections are integrally injection molded from rubber material. The force-applying sections have openings for adapting to the contours of the parts to be assembled or disassembled. A rigid skeleton block is embedded inside the force-applying section, and the rigid skeleton block is circumferentially arranged around the opening. A through hole is formed on the rigid skeleton block. During the injection molding process, molten rubber material passes through the through hole and covers the rigid skeleton block to form the force-applying section.

[0008] Furthermore, the edges on both sides of the opening protrude outward to form a thickened reinforcing portion.

[0009] Furthermore, multiple external mounting holes are provided around the opening, and internal mounting holes are provided at corresponding positions on the surface of the rigid skeleton block. The internal mounting holes are coaxially corresponding to the external mounting holes. The force-applying segment is fixed in the axial direction of the opening by passing bolts through the external mounting holes and internal mounting holes and tightening nuts.

[0010] Furthermore, there are two through holes, spaced apart between the three inner mounting holes; both the through holes and the inner mounting holes are located on the same circumference centered on the axis of the opening.

[0011] Furthermore, the external mounting hole is formed on the thickened and reinforced portion.

[0012] Furthermore, the rigid skeleton block includes a base plate and two claw arms fixed to both sides of the base plate, with the two claw arms fixedly arranged around the outside of the opening.

[0013] Furthermore, a weight-reducing through groove is provided in the middle of the connecting section.

[0014] This utility model provides a wrench for disassembling and assembling an optoelectronic connector. It has the following beneficial effects:

[0015] 1. The main body of the force-applying section is composed of a rigid skeleton block covered with rubber material. The rubber layer directly contacts the surface of the optoelectronic connector, effectively avoiding problems such as scratches, indentations, and wear caused by metal tools, and maximizing the protection of the structural integrity and surface finish of the precision housing or nut of the optoelectronic connector.

[0016] 2. The rigid skeleton block embedded inside the force application section surrounds the opening of the adapter connector, providing strong structural support and resistance to deformation. It can rigidly and efficiently transmit torque, ensuring stable and reliable force application, effectively preventing excessive deformation, twisting, and slippage that are prone to occur in pure rubber tools under high torque, and significantly improving the efficiency of assembly and disassembly operations.

[0017] 3. The connecting section is made of rubber, exhibiting significant elasticity and flexibility. When torque is applied during connector assembly or disassembly, the connecting section undergoes significant elastic bending deformation. This deformation process absorbs and dissipates some energy. When significant deformation occurs in the connecting section, the operator can clearly feel a sharp increase in resistance, indicating that the safe torque limit has been reached. Applying force should be stopped immediately, enhancing operational controllability and safety, and reducing the risk of misoperation. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] See attached document Figure 1-2 A wrench for disassembling and assembling an optoelectronic connector includes a connecting section 1 and force-applying sections 2 fixedly connected to both ends of the connecting section 1. The connecting section 1 and the force-applying sections 2 are integrally injection molded from rubber material. The force-applying sections 2 have openings 3 for adapting to the contours of the component being disassembled (optoelectronic connector). A rigid skeleton block 4 (made of metal or high-strength engineering plastic) is embedded inside the force-applying section 2, and the rigid skeleton block 4 is arranged circumferentially around the opening 3. A through hole 8 is formed on the rigid skeleton block 4. During the injection molding process, molten rubber material passes through the through hole 8 and covers the rigid skeleton block 4 to form the force-applying section 2. The molten rubber passes through the through hole 8 on the rigid skeleton block 4, and after molding, the rigid skeleton block 4 and the rubber covering it form a mechanical interlock, tightly combined into a whole. The rigid skeleton block 4 bears the main structural load, while the rubber provides coverage, cushioning, and flexible connection with the connecting section 1.

[0023] Working principle: In use, align and engage the opening 3 at the end of the force-applying section 2 with the optoelectronic connector (or its compatible nut / housing) that needs to be disassembled or assembled, and then turn the other end of the force-applying section to disassemble or assemble the optoelectronic connector. The rigid skeleton block 4 embedded inside the force-applying section 2 surrounds the opening 3 that conforms to the contour of the optoelectronic connector, providing strong structural support and resistance to deformation for the force-applying section 2. Covering the rigid skeleton block 4 avoids scratches, indentations, or wear that may be caused by metal tools, protecting the appearance and structural integrity of the optoelectronic connector. The rigid skeleton block 4 rigidly transmits torque, ensuring that torsional force is stably applied to the optoelectronic connection. It prevents the rubber force-applying section 2 from excessively deforming or slipping under strong force, ensuring efficient force application. The connecting segment 1 has significant elasticity and flexibility, making it more prone to elastic bending deformation when subjected to torsional force. When the applied torque is used to assemble or disassemble the optoelectronic connector, the rubber material of the connecting segment 1 will undergo significant bending deformation. This deformation absorbs and consumes some energy, while significantly increasing the difficulty of applying a larger torque. It actively limits the maximum torque transmitted to the optoelectronic connector, effectively preventing structural damage such as stripping, breakage, and deformation of the optoelectronic connector or its interface due to excessive force.

[0024] In addition, the edges on both sides of the opening 3 protrude outward to form thickened reinforcements, which enhance the strength and wear resistance of the high-stress area, prevent tearing, and at the same time, increase the contact length with the optoelectronic connector in the axial direction of the opening 3 to prevent loosening.

[0025] Multiple external mounting holes 6 are provided around the opening 3, and corresponding internal mounting holes 7 are provided on the surface of the rigid skeleton block 4. The internal mounting holes 7 and the external mounting holes 6 are coaxially aligned. By passing bolts through the external mounting holes 6 and the internal mounting holes 7 and tightening the nuts, the force-applying section 2 is fixed in the axial direction of the opening 3. The rubber layer of the force-applying section 2 is clamped onto the rigid skeleton block 4 by the bolts and nuts, which effectively prevents the rubber layer from slipping or peeling off relative to the rigid skeleton block 4 under high torque, ensuring effective force transmission. The external mounting holes 6 are provided on the thickened reinforcing part 5. When the bolts are fixed, they are located in the thicker rubber reinforcing part 5, which increases the stability and reliability of the structure.

[0026] There are two through holes 8, which are spaced apart between the three inner mounting holes 7. Both the through holes 8 and the inner mounting holes 7 are located on the same circumference centered on the axis of the opening 3, ensuring that the rigid skeleton block 4 is stably connected to the rubber wrapped around it in the circumferential direction.

[0027] In this embodiment, the rigid skeleton block 4 includes a base plate 42 and two claw arms 41 fixed to both sides of the base plate 42. The two claw arms 41 are fixedly arranged around the outside of the opening 3. The claw arms 41 provide additional support and constraint for the rubber outside the opening 3, thereby enhancing the overall torsional stiffness of the force-applying section 2.

[0028] A weight-reducing through groove 9 is provided in the middle of the connecting section 1, thereby reducing the rigidity of the connecting section 1 and making it easier to undergo the required flexible bending and torsional deformation. The deformation characteristics actively limit the maximum output torque, provide an overload protection structure, and reduce the weight of the tool. The torque limiting function provides intuitive force feedback. When the connecting section 1 undergoes significant deformation, the operator can clearly feel a sharp increase in resistance, indicating that the safe torque limit has been reached and force should be stopped immediately, enhancing the controllability and safety of operation.
