Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber threading auxiliary tools, and in particular to a JUMPER fixation fixture for fiber threading. Background Technology
[0002] In fiber optic communication systems, jumpers, as crucial fiber optic connectors, are widely used for fiber optic network connections and signal transmission. During jumper manufacturing, the fiber must be precisely threaded into the jumper's internal threading channels. This threading process directly impacts the jumper's connection performance and signal transmission quality. Traditional jumper threading is typically done manually, requiring the operator to hold the jumper in place with one hand while manipulating the fiber with the other. This method has several drawbacks. First, manually holding the jumper is prone to positional shifts and jitter, leading to deviations during fiber insertion and affecting threading accuracy and success rate. Second, during the threading process, it's difficult for the operator to simultaneously maintain jumper stability and control the threading motion.
[0003] Furthermore, existing fiber threading operations lack effective visualization methods, making it difficult for operators to clearly observe the fiber's insertion status inside the jumper and promptly detect problems during the process, such as fiber jamming, bending, or deviation from the intended path. This lack of visibility is particularly pronounced in mass production environments, impacting production efficiency and increasing the difficulty of product quality control. While some simple fixing devices exist on the market, these devices are typically rudimentary in structure, offer unsatisfactory fixing results, and lack specific design considerations for fiber threading operations, failing to meet the precision and efficiency requirements of modern fiber optic communication equipment manufacturing. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a JUMPER fixation fixture for fiber threading that provides stable fixation and good visibility of the fiber threading operation.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A jumber fixing fixture for threading fibers includes: a base; a receiving groove disposed on the base for holding the jumber; and a clamping device including: a pivot seat disposed on the base, and a clamping member pivotally connected to the pivot seat. The clamping member includes a pressure rod near the receiving groove and a pressure tail away from the receiving groove, and an elastic member acting on the pressure tail. The pressure rod has a first pressure arm and a second pressure arm spaced apart at one end near the receiving groove. A clearance area for observing the threading is formed between the first pressure arm and the second pressure arm. The elastic member acts on the pressure tail, driving the clamping member to rotate around the pivot seat, so that the first pressure arm and the second pressure arm clamp the jumber.
[0007] Furthermore, the pressure rod is pivotally connected to the rotating shaft seat, the pressure rod and the pressure tail are in a "T" shape, and the elastic element acts on both ends of the pressure tail respectively.
[0008] Furthermore, the lower surfaces of both ends of the pressure tail are respectively provided with first mounting holes, and the upper surface of the base is correspondingly provided with second mounting holes coaxial with the first mounting holes. The elastic element is a spring, which is installed in the first mounting hole and the second mounting hole respectively. The length of the spring in its natural state is greater than the distance between the first mounting hole and the second mounting hole, so that the spring is in a compressed state and pushes the pressure tail upward.
[0009] Furthermore, the receiving groove is a recess provided on the upper surface of the base. The receiving groove includes a first groove segment and a second groove segment, which are connected. The first groove segment is located inside the base, and the second groove segment extends outward from the edge of the base.
[0010] Furthermore, it also includes a positioning block, which is disposed in the first groove segment and at one end away from the second groove segment. The second groove segment forms an opening at the end away from the first groove segment. JUMPER is inserted through the opening and slides along the second groove segment toward the first groove segment until it abuts against the positioning block to achieve positioning.
[0011] Furthermore, the positioning block is detachably disposed within the first groove section.
[0012] Furthermore, the first pressure arm and the second pressure arm extend from the front end of the pressure rod and are parallel to each other. The free ends of the first pressure arm and the second pressure arm are respectively provided with "L"-shaped pressing sections facing the clearance area. The pressure rod, the first pressure arm and the second pressure arm are in a fork-shaped structure. The clearance area is located between the first pressure arm and the second pressure arm, forming a rectangular opening for observing the fiber threading operation.
[0013] Furthermore, the clearance area is located above the receiving groove in the vertical direction, and the opening area of the receiving groove is located within the vertical projection range of the clearance area on the horizontal plane.
[0014] Furthermore, the pivot seat and the base are connected by fasteners.
[0015] Furthermore, the JUMPER includes a main body and a fiber-threading channel disposed on the main body. The fiber-threading channel includes a first channel and a second channel. The first channel is a semi-open channel, and the second channel is a circular through-hole penetrating the main body and communicating with the first channel. The optical fiber can be pushed into the second channel along the first channel to complete the fiber threading. Two protruding supports are disposed on the side of the main body away from the first channel. The second channel is located between the two supports. When the JUMPER is installed in the receiving groove, the supports abut against the bottom of the receiving groove, and an observation gap is formed between the two supports. The end of the optical fiber after passing through the second channel can be observed through the observation gap.
[0016] The beneficial effects of this utility model are:
[0017] A jumber fixing fixture for fiber optic cable insertion includes a base, a receiving groove disposed on the upper surface of the base, and a clamping device. The clamping device includes a rotating shaft seat, a clamping member pivotally connected to the rotating shaft seat, and an elastic member acting on the clamping member. The clamping member includes a pressure rod, a first pressure arm and a second pressure arm extending from the front end of the pressure rod, and a clearance area is formed between the first pressure arm and the second pressure arm. When the jumber is placed in the receiving groove, the elastic member drives the clamping member to rotate around the rotating shaft seat, so that the first pressure arm and the second pressure arm clamp the jumber and keep it in a fixed state. At the same time, the clearance area provides observation space for the fiber insertion operation. Technicians can observe the process of pushing the optical fiber along the fiber insertion channel of the jumber through the clearance area. This fixture achieves reliable jumber fixing and control of the fiber insertion process through the clamping of the clamping device and the visualization of the clearance area, improving the efficiency and quality of optical fiber insertion operations. It is particularly suitable for batch processing and precision fiber insertion operations of jumbers in the manufacturing of optical fiber communication equipment. Attached Figure Description

Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0029] Reference Figure 1-2A JUMPER300 fixing fixture for threading fibers includes a base 100, a receiving groove 110, and a clamping device 200. The receiving groove 110 is disposed on the base 100 for placing JUMPER300; the clamping device 200 includes: a rotating shaft seat 210 disposed on the base 100, a clamping member 220 pivotally connected to the rotating shaft seat 210, the clamping member 220 including a pressure rod 221 near the receiving groove 110 and a pressure tail 222 away from the receiving groove 110, and an elastic member 230 acting on the pressure tail 222. The pressure rod 221 is provided with a first pressure arm 223 and a second pressure arm 224 at intervals near the receiving groove 110. An empty area 226 for observing fiber threading is formed between the first pressure arm 223 and the second pressure arm 224. The elastic member 230 acts on the pressure tail 222, driving the clamping member 220 to rotate around the rotating shaft seat 210, so that the first pressure arm 223 and the second pressure arm 224 clamp JUMPER300.
[0030] Understandably, when the JUMPER300 needs to be threaded, it is first placed in the receiving groove 110 provided on the base 100, where the pivot seat 210 is fixed on the base 100 as a support point, and the clamping member 220, which is pivotally connected to the pivot seat 210, can rotate around the pivot seat 210. The clamping member 220 includes a pressure rod 221 part near the receiving groove 110 and a pressure tail 222 part away from the receiving groove 110. The front end of the pressure rod 221 A first pressure arm 223 and a second pressure arm 224 are spaced apart. The clearance area 226 formed between these two pressure arms provides a viewing channel for observing the fiber threading operation. At the same time, the elastic element 230 acting on the pressure tail 222 continuously applies downward pressure, driving the entire clamping member 220 to rotate around the rotating shaft seat 210. This allows the first pressure arm 223 and the second pressure arm 224 to effectively clamp the JUMPER300 placed in the receiving groove 110, ensuring that the JUMPER300 remains stable during the fiber threading process.
[0031] It should be noted that, referring to Figure 4The JUMPER300 described in this case includes a main body and a fiber-threading channel 310 disposed on the main body. The fiber-threading channel 310 includes a first channel 311 and a second channel 312. The first channel 311 is a semi-open channel, and the second channel 312 is a circular through hole penetrating the main body and communicating with the first channel 311. The optical fiber can be pushed into the second channel 312 along the first channel 311 to complete the fiber threading. Two protruding supports 320 are disposed on the side of the main body away from the first channel 311. The second channel 312 is located between the two supports 320. When the JUMPER300 is installed in the receiving groove 110, the supports 320 abut against the bottom of the receiving groove 110, and an observation gap is formed between the two supports 320. The end of the optical fiber after passing through the second channel 312 can be observed through the observation gap.
[0032] Specifically, the JUMPER300 body is equipped with a dedicated fiber-threading channel 310. This fiber-threading channel 310 adopts a segmented design, including two parts: a first channel 311 and a second channel 312. The first channel 311 is a semi-open channel, which allows the optical fiber to be easily placed in the channel without slipping. The second channel 312 is a circular through-hole that penetrates the body and is connected to the first channel 311, forming a progressive fiber-threading path from open to closed. The optical fiber can be placed in the semi-open channel of the first channel 311 first, and then gradually pushed into the second channel 312 along the first channel 311 to complete the entire fiber-threading process. At the same time, two protruding supports 320 are provided on the side of the JUMPER300 body away from the first channel 311. When the JUMPER300 is installed in the receiving slot 110, the supports 320 abut against the bottom of the receiving slot 110 to ensure the stable positioning of the JUMPER300. The observation gap formed between the two supports 320 provides a visual confirmation channel for the fiber-threading operation.
[0033] In some embodiments, refer to Figure 1-3The pressure rod 221 is pivotally connected to the rotating shaft seat 210. The pressure rod 221 and the pressure tail 222 are in a "T" shape. The elastic element 230 acts on both ends of the pressure tail 222. It should be noted that the pressure rod 221, as the main force transmission component, is directly pivotally connected to the rotating shaft seat 210, forming the fulcrum for rotational motion. The pressure rod 221 and the pressure tail 222 are arranged in a "T" shape, that is, the pressure rod 221 is the vertical part of the "T", and the pressure tail 222 is the horizontal beam part of the "T". The elastic elements 230 act on both ends of the pressure tail 222 respectively. Through the symmetrically distributed double elastic elements 230, it can be ensured that the pressure tail 222 remains horizontal under the action of the elastic elements 230 and generates a uniform upward thrust. This thrust is transmitted to the pressure rod 221 through the "T" shaped connection structure, thereby driving the pressure rod 221 to rotate around the rotating shaft seat 210, and finally causing the first pressure arm 223 and the second pressure arm 224 to apply a uniform and stable clamping force to the JUMPER300.
[0034] Furthermore, refer to Figure 3 The lower surfaces of both ends of the pressure tail 222 are respectively provided with first mounting holes 2221, and the upper surface of the base 100 is correspondingly provided with second mounting holes 113 coaxial with the first mounting holes 2221. The elastic element 230 is a spring, which is installed in the first mounting holes 2221 and the second mounting holes 113 respectively. The length of the spring in its natural state is greater than the distance between the first mounting holes 2221 and the second mounting holes 113, so that the spring is in a compressed state and pushes the pressure tail 222 upward. It can be understood that the lower surfaces of both ends of the pressure tail 222 are respectively provided with first mounting holes 2221, which provide upper positioning and accommodation space for the spring. At the same time, the upper surface of the base 100 is correspondingly provided with second mounting holes 113 coaxial with the first mounting holes 2221, forming a pairing hole system structure. The elastic element 230 is in the form of a spring and is installed in the first mounting holes 2221 and the second mounting holes 113 respectively. Through this matching installation method of the upper and lower hole system, the spring can maintain good axial alignment and stability. In addition, the pre-compression ensures that the spring remains compressed after installation, thereby continuously pushing the pressure tail 222 upward and ensuring that the clamping device 200 has a constant force.
[0035] In some embodiments, refer to Figure 1 , 2The receiving groove 110 is a groove provided on the upper surface of the base 100. The receiving groove 110 includes a first groove segment 111 and a second groove segment 112. The first groove segment 111 and the second groove segment 112 are connected. The first groove segment 111 is located inside the base 100, and the second groove segment 112 extends outward from the edge of the base 100. Understandably, the receiving slot 110 is divided into two functionally different slots, namely the first slot 111 and the second slot 112. These two slots are interconnected to form a continuous receiving channel. The first slot 111 is located entirely inside the base 100, providing a stable main receiving space for the JUMPER300. The second slot 112 extends outward from the edge of the base 100, forming an open feeding channel that extends beyond the boundary of the base 100. This allows the JUMPER300 to be easily inserted from the open end of the second slot 112 and then slide along the connected slot into the first slot 111 for final positioning. The extended design of the second slot 112 not only facilitates the loading operation of the JUMPER300 but also provides ample receiving space for the longer JUMPER300.
[0036] Furthermore, refer to Figure 2 It also includes a positioning block 114, which is disposed in the first groove segment 111 and away from the end of the second groove segment 112. The end of the second groove segment 112 away from the first groove segment 111 forms an opening. The JUMPER300 is inserted through the opening and slides along the second groove segment 112 toward the first groove segment 111 until it abuts against the positioning block 114 to achieve positioning. Understandably, the JUMPER300 is first placed into the receiving slot 110 system through the opening of the second slot 112, and then slid along the second slot 112 towards the first slot 111 under the push of the operator. When the JUMPER300 continues to move forward and enters the first slot 111, it will continue to slide until it abuts against the positioning block 114. At this time, the positioning block 114 acts as a stop to ensure that the JUMPER300 is accurately positioned in the first slot 111. This not only ensures that each loaded JUMPER300 reaches the same positioning position, but also provides a standardized working benchmark for the subsequent operation of the clamping device 200.
[0037] In this further embodiment, the positioning block 114 adopts a detachable design, which realizes the multi-specification adaptability and maintenance convenience of the JUMPER300 fixing fixture through flexible installation and configuration. Specifically, the positioning block 114 is detachably set in the first slot section 111, so that the positioning block 114 can be removed from the first slot section 111 or reinstalled as needed, thereby providing customized positioning solutions for JUMPER300 of different specifications and lengths. At the same time, when the positioning block 114 is worn or damaged, it can also be easily replaced and maintained without replacing the entire fixing fixture. This modular design not only reduces equipment maintenance costs, but also improves the flexibility and adaptability of the production line. The detachable feature of the positioning block 114 allows operators to adjust the positioning position of the JUMPER300 according to the specific fiber threading task requirements, or temporarily remove the positioning block 114 when handling special specifications of JUMPER300.
[0038] In some embodiments, refer to Figure 2 , 3 The first pressure arm 223 and the second pressure arm 224 extend from the front end of the pressure rod 221 and are parallel to each other. The free ends of the first pressure arm 223 and the second pressure arm 224 are respectively provided with "L"-shaped pressing sections 225 facing the clearance area 226. The pressure rod 221, the first pressure arm 223 and the second pressure arm 224 are in a fork-shaped structure. The clearance area 226 is located between the first pressure arm 223 and the second pressure arm 224, forming a rectangular opening for observing the fiber threading operation. Understandably, the first pressure arm 223 and the second pressure arm 224 extend from the front end of the pressure rod 221 and are arranged parallel to each other to ensure that a uniformly distributed clamping force is applied to both ends of the JUMPER300, avoiding deformation or damage to the JUMPER300 that may be caused by single-point force. At the same time, the free ends of the first pressure arm 223 and the second pressure arm 224 are respectively provided with "L"-shaped clamping sections 225 facing the clearance area 226. The "L"-shaped design allows the clamping sections 225 to better fit the surface contour of the JUMPER300 and provide a stable clamping force. The entire pressure rod 221, the first pressure arm 223 and the second pressure arm 224 form an integral fork-shaped structure, similar to the shape of a fork. The clearance area 226 is located between the first pressure arm 223 and the second pressure arm 224, forming a rectangular opening for observing the fiber threading operation. This rectangular opening provides technicians with a clear field of vision, allowing key operating steps in the fiber threading process to be directly observed and monitored.
[0039] In some embodiments, refer to Figure 1-3The clearance area 226 is located vertically above the receiving groove 110, and the opening area of the receiving groove 110 is within the vertical projection range of the clearance area 226 on the horizontal plane. Specifically, the clearance area 226, located vertically above the receiving groove 110, provides an ideal visual channel for vertical observation from above. Furthermore, the opening area of the receiving groove 110 is within the vertical projection range of the clearance area 226 on the horizontal plane. When the operator observes downwards from the clearance area 226, all key areas within the receiving groove 110 can be completely covered within the field of vision, eliminating blind spots and ensuring that every detail of the fiber threading operation can be clearly monitored and confirmed, providing visual support for the fiber threading operation.
[0040] In some embodiments, refer to Figure 1 , 2 The rotating shaft seat 210 is connected to the base 100 by fasteners. It is understood that the rotating shaft seat 210 can withstand the continuous force transmitted from the elastic element 230 through the clamping element 220, as well as various dynamic loads generated during the fiber threading operation. Furthermore, when equipment maintenance, cleaning, or adjustment of the working position of the clamping device 200 is required, the detachable rotating shaft seat 210 allows operators to separate the rotating shaft seat 210 from the base 100 by removing the fasteners, thereby achieving the overall disassembly or repositioning of the clamping device 200.
[0041] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model.
