Description

Technical Field

[0001] The invention belongs to the technical field of power communication auxiliary equipment, and more specifically, relates to a pigtail plugging and unplugging tool. Background Art

[0002] Pigtail refers to an optical fiber or optical cable with an optical fiber connector installed at one end and an optical connection line of the optical fiber or optical cable at the other end. In the prior art, the optical fiber connectors installed in the pigtail are mainly divided into four types: LC, FC, SC, and ST.

[0003] With the emergence of concepts such as Internet+ and digital economy, the demand for computing, storage and other resources has soared, the scale of information and communication equipment has increased exponentially, and the number and types of fiber pigtails plugged into communication equipment have also increased. At present, fiber pigtails are generally plugged and unplugged manually. However, since there are many fiber pigtails in the cabinet and plugged together on the matching fiber optic connection equipment, many fiber optic connectors are arranged together, making the fiber optic connectors densely arranged and the equipment space narrow. It is very difficult to plug and unplug one of the fiber pigtails manually, and it is also easy to damage the fiber pigtail connector.

[0004] Existing pigtail plugging and pulling tools only support the plugging and pulling of a single type of active connector. Operation and maintenance personnel often need to carry multiple different types of pigtail plugging and pulling tools at a time to adapt to the plugging and pulling operations of different types of pigtails. Frequent replacement of plugging and pulling tools during operations not only increases the labor intensity of operation and maintenance personnel, but also easily leads to incorrect use of tools, resulting in damage to the pigtail. Summary of the invention

[0005] The purpose of the present invention is to provide a pigtail plugging and extraction tool to solve the technical problem of the single applicable type of pigtail plugging and extraction tool in the prior art. The pigtail plugging and extraction tool provided by the present invention is at least suitable for plugging and unplugging LC and FC type pigtail connectors.

[0006] To achieve the above object, the technical solution adopted by the present invention is to provide a pigtail plugging and unplugging tool, comprising:

[0007] A gripping member, one end of which is provided with two spaced-apart and mutually symmetrical connecting arms;

[0008] Two clamping arms, one end of which is provided with a first clamp for clamping an LC type connector, and the other end of which is provided with a second clamp for clamping an FC type connector. The two clamping arms are symmetrically arranged and are rotatably connected to the inner side of the connecting arm in a one-to-one manner.

[0009] In a possible implementation, the middle portion of the clamping arm is rotatably connected to an end of the connecting arm away from the holding component.

[0010] In a possible implementation manner, the first clamp is L-shaped.

[0011] In a possible implementation, the second clamp is an arc-shaped plate, and a convex side of the arc-shaped plate is hinged to the clamping arm.

[0012] In a possible implementation manner, the arc-shaped cross-section of the arc-shaped plate is perpendicular to the length direction of the clamping arm.

[0013] In one possible implementation, an anti-rotation component is provided on the connecting arm, and the anti-rotation component includes a second rotating shaft that transversely passes through the connecting arm and vertical plates symmetrically arranged on both sides of the second rotating shaft. The vertical plates rotate with the second rotating shaft and cover the clamping arm to limit the rotation of the clamping arm.

[0014] In a possible implementation manner, a magnetic component is provided at one end of the holding component away from the connecting arm.

[0015] In a possible implementation, a wire is connected to the gripping portion, and the other end of the wire is connected to an alligator clip.

[0016] In a possible implementation, an end of the holding component away from the connecting arm is provided with an end cap, a resistor is provided inside the end cap, and the resistor is electrically connected between the holding component and the wire.

[0017] In a possible implementation manner, an elastic conductive component is provided between the resistor and the holding component.

[0018] The beneficial effect of the pigtail plugging and unplugging tool provided by the present invention is that compared with the prior art, when using the pigtail plugging and unplugging the LC-type connector, one end of the first clamp set on the clamping arm is rotated to the side away from the holding component, and the two connecting arms are pinched with hands to make the spaced connecting arms approach each other, thereby driving the two clamping arms connected to the inner sides of the connecting arms to approach each other, so that the two symmetrically arranged first clamps can clamp the LC-type connector for plugging and unplugging. When plugging and unplugging the FC-type connector, one end of the second clamp set on the clamping arm is rotated to the side away from the holding component, and then the same operation as above is performed to complete the clamping and plugging and unplugging of the FC-type connector by the second clamp.

[0033] See also Figures 1 to 6 The pigtail plugging and unplugging tool provided by the present invention is now described. A pigtail plugging and unplugging tool comprises a gripping component 1 and two clamping arms 3, one end of the gripping component 1 is provided with two spaced and mutually symmetrical connecting arms 2; one end of the clamping arm 3 is provided with a first clamp 31 for clamping an LC type connector, and the other end of the clamping arm 3 is provided with a second clamp 32 for clamping an FC type connector, the two clamping arms 3 are symmetrically arranged and rotatably connected to the inner side of the connecting arm 2 in a one-to-one corresponding manner.

[0034] Compared with the prior art, the pigtail plugging and unplugging tool provided by the present invention is that when using the present device to plug and unplug an LC-type connector, one end of the first clamp 31 provided on the clamping arm 3 is rotated to the side away from the holding part 1, and the two connecting arms 2 are pinched by hand to make the spaced connecting arms 2 approach each other, thereby driving the two clamping arms 3 connected to the inner side of the connecting arms 2 to approach each other, so that the two symmetrically arranged first clamps 31 can clamp the LC-type connector for plugging and unplugging. When plugging and unplugging an FC-type connector, one end of the second clamp 32 provided on the clamping arm 3 is rotated to the side away from the holding part 1, and then the plugging and unplugging of the FC-type connector by the second clamp 32 can be completed through the same operation as above. The pigtail plugging and unplugging tool provided by the present invention can at least adapt to the plugging and unplugging of two types of pigtail connectors, LC and FC, which reduces the operation of frequent replacement of different types of plugging and unplugging tools by operation and maintenance personnel during the operation, thereby improving work efficiency.

[0035] Among them, in order to realize the rotational connection between the clamping arm 3 and the connecting arm 2, a first rotating shaft 4 is arranged in a direction perpendicular to the inner wall of the connecting arm 2 and penetrating the connecting arm 2 and the clamping arm 3, and baffles 41 are arranged on both sides of the first rotating shaft 4. The baffle 41 on the outer side of the first rotating shaft 4 is in contact with the outer side of the connecting arm 2, and the baffle 41 on the inner side of the first rotating shaft 4 is in contact with the inner side of the clamping arm 3. With such an arrangement, on the one hand, the clamping arm 3 can rotate around the first rotating shaft 4 on the inner side of the connecting arm 2, and on the other hand, the baffle 41 can prevent the clamping arm 3 and the connecting arm 2 from detaching from each other.

[0036] For further information, see Figure 1 The first rotating shaft 4 is arranged at one end of the connecting arm 2 away from the holding part 1, the middle part of the clamping arm 3 is connected to the first rotating shaft 4, and the length of the first rotating shaft 4 along the length direction of the connecting arm 2 to the holding part 1 is greater than half of the length of the clamping arm 3. In this arrangement, the clamping arm 3 can rotate 360° around the first rotating shaft 4 without being interfered by the holding part 1.

[0037] For further information, see Figure 2 , the lateral width of the connecting arm 2 gradually decreases from the connecting end with the gripping component 1 to the other end. With this arrangement, on the one hand, the lateral width of the connecting end of the connecting arm 2 and the gripping component 1 is maximized, thereby strengthening the connection strength between the connecting arm 2 and the gripping component 1. On the other hand, by gradually narrowing the lateral width, the connecting arm 2 can be used in a narrow working environment. In actual operation, the gripping component 1 of the present invention is held in one hand, and the two connecting arms 2 are pinched by fingers to drive the clamping arms 3 closer to each other. The finger force position is just in the area where the width of the connecting arm 2 gradually changes. This requires that the connection strength between the connecting arm 2 and the gripping component 1 is relatively strong, so that the connecting arm 2 is not easy to break.

[0038] Optionally, the connecting arm 2 and the holding component 1 are formed in one piece, and such a configuration enables a good connection effect between the connecting arm 2 and the holding component 1.

[0039] Furthermore, the connecting arm 2 is detachably connected and fixed to the gripping member 1. The detachable connection method may be to insert the connecting arm 2 into the gripping member 1, or to fix the connecting arm 2 to the gripping member 1 by screws 201.

[0040] In this example, see Figure 7The connecting arm 2 is made of insulating plastic, such as polyethylene plastic; the gripping part 1 is made of conductive metal material, such as aluminum alloy, carbon steel, etc.; a mounting groove is provided on the side wall of the gripping part 1, and a threaded hole is provided in the groove. A through hole for inserting a screw 201 is correspondingly provided on the connecting arm 2. When installing, first clamp the connecting arm 2 in the mounting groove, align the through hole on the connecting arm 2 with the threaded hole on the mounting groove, and then pass the screw 201 through the connecting arm 2 and connect it in the threaded hole. Rotate and tighten the screw 201, so that the screw 201 fastens the connecting arm 2 to the gripping part 1. The connecting arm 2 of different materials is fixedly connected to the gripping part 1 by the screw 201.

[0041] Furthermore, the number of screws 201 is plural.

[0042] Optionally, the number of the screws 201 is 3, and the three screws 201 are distributed in a herringbone structure.

[0043] See also Figures 1 to 6 As a specific implementation of the pigtail plugging and extraction tool provided by the present invention, the connecting arm 2 is provided with an anti-rotation member 5 for limiting the rotation of the clamping arm 3.

[0044] In this embodiment, the width of the clamping arm 3 is the same as the width of the end of the connecting arm 2 away from the holding part 1, and an anti-rotation component 5 is provided on the side of the first rotating shaft 4 on the connecting arm 2 close to the holding part 1, and the anti-rotation component 5 includes a second rotating shaft 51 that transversely passes through the connecting arm 2, and vertical plates 52 connected to both sides of the second rotating shaft 51 and a horizontal plate 53 connected between the two vertical plates 52 away from the second rotating shaft 51, and the width of the horizontal plate 53 is equivalent to the width of the connecting arm 2, wherein the second rotating shaft 51 is connected to the corners of the vertical plates 52. In actual application, the clamping arm 3 is rotated so that the length direction of the clamping arm 3 is the same as that of the connecting arm 2, and then the anti-rotation component 5 is rotated toward the inside of the connecting arm 2 around the second rotating shaft 51, so that the horizontal plate 53 is fitted with the outer wall of the connecting arm 2, so that the vertical plate 52 can cover the lateral side walls of the connecting arm 2 and the clamping arm 3 at the same time. In this way, under the constraints of the two vertical plates 52 and the horizontal plate 53, the clamping arm 3 no longer rotates. If the clamping arm 3 needs to be rotated again, the anti-rotation member 5 needs to be rotated around the second rotation axis 51 toward the outside of the connecting arm 2 so that the vertical plate 52 no longer covers the clamping arm 3, thereby freeing the clamping arm 3 from constraint and being able to rotate again.

[0045] See also Figures 4 to 6 As a specific implementation of the pigtail plugging and unplugging tool provided by the present invention, the first clamp 31 is L-shaped.

[0046] In the present embodiment, the first clamp 31 is used to clamp the LC type connector. Since the LC type connector is relatively small in size and the density of plugging on the communication equipment is relatively high, and the reserved space between similar LC type pigtails is narrow, the first clamp 31 is set to be L-shaped, wherein the head of the L-shaped first clamp 31 is one end connected to the clamping arm 3, and the tail of the L-shaped first clamp 31 is the end away from the clamping arm 3, so that the lateral width of the head of the L-shaped first clamp 31 is smaller than the lateral width of the clamping arm 3, so as to facilitate adaptation to the smaller LC type connector. The lateral width of the tail of the L-shaped first clamp 31 is twice the lateral width of its head. With this arrangement, when clamping the LC type connector, the laterally protruding part of the tail of the L-shaped first clamp 31 can be used to clamp the LC type connector from the side of the pigtail, thereby solving the problem of interference caused by the pigtail cable when clamping the pigtail connector from the rear.

[0047] For further information, see Figure 5 A reinforcement section 312 is provided at the connection between the L-shaped first clamp 31 and the clamping arm 3. The lateral width of the reinforcement section 312 gradually increases from one end of the L-shaped first clamp 31 to one end of the clamping arm 3. By providing the reinforcement section 312, the connection strength between the clamping arm 3 and the L-shaped first clamp 31 is increased and is not easily damaged.

[0048] For further information, see Figure 1 , Figure 4 and Figure 5 An anti-slip structure 311 is provided on the inner side wall of the tail of the L-shaped first clamp 31 , wherein the anti-slip structure 311 can be a convex ridge arranged laterally and protruding inward, or a plastic layer sprayed on the inner side of the L-shaped first clamp 31 .

[0049] See also Figure 1 and Figure 2 As a specific embodiment of the pigtail plugging and unplugging tool provided by the present invention, the second clamp 32 is an arc-shaped plate, and the convex side of the arc-shaped plate is hinged on the clamping arm 3; the axial direction of the arc-shaped plate is the same as the length direction of the clamping arm 3.

[0050] In this embodiment, the second clamp 32 is configured as an arc-shaped plate, and a bracket 321 is provided on the convex side of the arc-shaped plate. The end of the clamping arm 3 connected to the second clamp 32 is a round head, and a through slot 301 penetrating the inner and outer walls of the clamping arm 3 is provided on the end surface of the round head. The through slot 301 is provided with a transverse shaft 302. A bracket 321 is provided on the convex side of the arc-shaped plate, and one end of the bracket 321 is located inside the through slot 301; the transverse shaft 302 penetrates the bracket 321 and is connected to the two side walls of the through slot 301, and the arc-shaped plate can rotate around the transverse shaft 302. In addition, the axial direction of the arc-shaped plate is the same as the length direction of the clamping arm 3. With such a configuration, the process of plugging in the FC-type connector is as follows:

[0051] First, clamp the arc plate on the inclined surface of the FC-type connector. Since the arc plate is hinged on the clamping arm 3, it can rotate around the transverse rotation axis 302 to adjust the clamping angle, so that the concave side surface of the arc plate can fit partially with the inclined surface of the FC-type connector. With the force of the two arc plates, friction can be generated between the inner surface of the arc plate and the inclined surface of the FC-type connector. The generated friction can be used to insert the FC-type connector into the adapter port.

[0052] Secondly, move the arc plate so that it clamps the outer wall of the nut on the FC type connector. The arc plate is rotated by the transverse rotating shaft 302 to adjust the clamping angle so that the inner wall surface of the arc plate fits with the outer wall surface of the nut of the FC type connector. Since the cross-section of the arc plate is arc-shaped, the inner surface of the arc plate and the outer wall surface of the nut have a larger contact area. When clamped with force, a larger friction force can be generated between the arc plate and the nut. At this time, by rotating the holding component 1, the arc plate can rotate with the holding component 1 under the action of the clamping force, thereby driving the nut on the FC type connector to rotate, so that the nut is connected to the device port, and the plugging of the FC type connector can be completed.

[0053] In addition, to disassemble the FC connector, just reverse the above process.

[0054] Furthermore, the inner wall surface of the arc plate is treated with anti-skid treatment, specifically, longitudinal convex ridges are provided, and the longitudinal convex ridges are provided to adapt to the longitudinal rolling grooves on the nut of the FC type connector; or the inner wall surface of the arc plate is sprayed with plastic to form a layer of plastic film on its surface. The anti-skid treatment can increase the friction force of the inner wall surface of the arc plate, so that the plugging and unplugging effect of the plugging and unplugging tool provided by the present invention on the FC type connector is better.

[0055] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 As a specific implementation of the pigtail plugging and unplugging tool provided by the present invention, a magnetic component 6 is provided at one end of the holding component 1 away from the connecting arm 2.

[0056] In this embodiment, the magnetic component 6 is a block magnet, which is embedded in the end of the holding component 1 away from the connecting arm 2. By setting the block magnet, the pigtail plugging and unplugging tool provided by the present invention can be adsorbed on the cabinet of the communication equipment, which is convenient for operation and maintenance personnel to use.

[0057] Optionally, a block magnet is embedded in the side wall of the gripping component 1. With such a configuration, when the gripping component 1 is adsorbed on the cabinet of the communication equipment through the block magnet, the length direction of the gripping component 1 is parallel to the cabinet surface, so that the height of the gripping component 1 protruding from the cabinet surface is small, thereby reducing the touch of the gripping component 1 by the operation and maintenance personnel during activities.

[0058] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 As a specific embodiment of the pigtail plugging and unplugging tool provided by the present invention, the holding component 1 can be conductive, and a wire 8 is connected to it, and the other end of the wire 8 is connected to an alligator clip 9.

[0059] In this embodiment, the holding part 1 is made of a metal material such as aluminum alloy or carbon steel, so that the holding part 1 can be conductive. A wire 8 is connected to one end of the holding part 1 away from the connecting arm 2, and the other end of the wire 8 is connected to an alligator clip 9. The alligator clip 9 is used to clamp on a grounded device. With such a configuration, when the operation and maintenance personnel hold the holding part 1 of the tool of the present invention, the human body can be connected to the ground, thereby eliminating the static electricity carried by the human body to prevent the static electricity from affecting the equipment.

[0060] Furthermore, the wire 8 is a stretchable elastic winding wire. The elastic winding wire can be stretched by the staff as needed, and when the external force is reduced, it will shrink due to the elastic force of the winding wire itself, which can ensure that the winding wire length is not too long, thereby reducing the impact of the wire 8 on the operation and maintenance personnel.

[0061] See also Figure 1 and Figure 4 As a specific embodiment of the pigtail plugging and unplugging tool provided by the present invention, an end cap 7 is provided at one end of the holding component 1 away from the connecting arm 2, and a resistor 10 is provided in the end cap 7, and the resistor 10 is electrically connected between the holding component 1 and the wire 8.

[0062] In this embodiment, the end cap 7 is made of a non-conductive material, such as plastic or rubber. The end cap 7 is connected to the holding part 1 by plugging or threading. A resistor 10 is embedded inside the end cap 7. The resistor 10 is electrically connected between the holding part 1 and the wire 8. The resistor 10 is provided to reduce the current flowing through the human body to a safe current, thereby avoiding the risk of electric shock to the human body.

[0063] Furthermore, the resistance of the resistor 10 is 1 to 3 megohms. Within the resistance range of 1 to 3 megohms, the current flowing through the human body can be better prevented and reduced, and the electrons can be smoothly moved to the grounding device to ensure the effect of removing static electricity.

[0064] See also Figure 1 and Figure 4As a specific embodiment of the pigtail plugging and unplugging tool provided by the present invention, an elastic component 11 is provided between the resistor 10 and the holding component 1 for electrically connecting the resistor 10 to the holding component 1 .

[0065] In this embodiment, a mounting hole 12 is provided on one side of the end cover 7 close to the holding part 1, and a metal spring is fixedly installed in the mounting hole 12. The metal spring is electrically connected to the resistor 10 arranged inside the end cover 7. When the end cover 7 is in a disassembled state, the metal spring is in a free state, and one end of the metal spring away from the resistor 10 protrudes outside the mounting end surface of the end cover 7. When the end cover 7 is installed on the holding part 1, the metal spring in the end cover 7 can first contact the holding part 1. When the end cover 7 is installed in place, the mounting end surface of the end cover 7 fits with the end of the holding part 1. At this time, the metal spring is compressed into the mounting hole 12. At the same time, the compressed metal spring can always rest against the holding part 1 under the action of its own elasticity, so that the electrical connection between the resistor 10 and the holding part 1 is stable and reliable.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
