Description

Technical Field

[0001] This invention relates to the field of spacer installation technology, and in particular to a spacer for separating adjacent bare conductors. Background Technology

[0002] Spacer bars are electrical fittings used in overhead lines (especially high-voltage and ultra-high-voltage bare conductor lines). Their main function is to maintain the distance between split conductors, prevent the conductors from colliding and rubbing against each other under the action of wind, electromagnetic force or vibration, and at the same time suppress the vibration of the conductors in the wind, ensuring the safe and stable operation of the line.

[0003] Currently, the locking mechanism between the spacer bar and the bare conductor usually uses a movable clamp and a fixed clamp to clamp the bare conductor. Specifically, the movable clamp is driven by a drive mechanism to slide horizontally to cooperate with the fixed clamp to clamp the bare conductor. However, in actual use, a large inlet needs to be formed between the movable clamp and the fixed clamp so that the UAV can lower the locking mechanism to the outside of the bare conductor. This results in the need to increase the size of the locking mechanism and the drive mechanism to accommodate the large movement stroke of the movable clamp, which increases the overall weight and material usage of the locking mechanism.

[0004] Therefore, it is necessary to provide a spacer bar for separating adjacent bare conductors to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a spacer bar for separating adjacent bare wires, in order to solve the problem mentioned in the background art that the size of the existing locking mechanism and drive mechanism needs to be increased to accommodate the large movement stroke of the moving clamp, resulting in an increase in the overall weight and material usage of the locking mechanism.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spacer bar for separating adjacent bare conductors, comprising a spacer bar and locking mechanisms installed at both ends of the spacer bar for respectively locking adjacent bare conductors. Each locking mechanism includes a fixed clamp and a movable clamp, with an inlet formed between the fixed clamp and the movable clamp. The top of the fixed clamp is a base, and the movable clamp is movably disposed on one side of the base. The movable clamp has a rotational stroke and a horizontal sliding stroke relative to the fixed clamp. During the rotational stroke, the movable clamp has a horizontal state perpendicular to the fixed clamp and a vertical state aligned with the fixed clamp. A screw is rotatably disposed on the fixed clamp, and a screw hole is provided on the movable clamp. When the movable clamp rotates from the horizontal state downwards to the vertical state, the screw hole and the screw are engaged together. The screw rotates under the drive of the drive mechanism to engage with the screw hole thread, so that the movable clamp performs a horizontal sliding stroke to clamp the bare conductor close to the fixed clamp.

[0007] Furthermore, the hinge block fixedly connected to the movable clamp and the hinge seat slidably connected to the base are rotatably connected via a connecting shaft. A locking mechanism is provided between the hinge seat and the base. The locking mechanism is configured to have the following two working positions: working position one, which locks the hinge seat to the base in response to the horizontal state of the movable clamp; working position two, which unlocks the hinge seat from the base in response to the vertical state of the movable clamp.

[0008] Furthermore, the locking mechanism includes a sliding frame vertically slidably connected to a slot on the side of the hinge seat and a plug rod fixedly connected to the top of the sliding frame. A first elastic element is provided between the sliding frame and the hinge seat. When the first elastic element releases its elastic force, it drives the sliding frame to move upward so that the plug rod is inserted into the slot on the base. The connecting shaft is fixedly connected to the hinge block and passes through the inside of the sliding frame. A protrusion is provided on the circumferential side of the connecting shaft. During the process of the moving clamp rotating from a horizontal state to a vertical state, the locking mechanism switches from station one to station two. The protrusion presses against the bottom surface of the sliding frame, causing the sliding frame to move downward relative to the hinge seat, so that the plug rod moves out of the slot.

[0009] Furthermore, a sleeve is coaxially rotatably connected to the connecting shaft, and the sleeve is slidably fitted with the base. A third elastic element is provided between the connecting shaft and the sleeve. When the third elastic element releases its elastic force, it drives the connecting shaft to rotate relative to the sleeve, so that the moving clamp rotates from a horizontal state to a vertical state.

[0010] Furthermore, the third elastic element includes a spiral spring or a torsion spring, one end of which is connected to the sleeve and the other end of which is connected to the connecting shaft.

[0011] Furthermore, the driving mechanism includes a motor embedded in a fixed clamp and a bushing that is connected to the output end of the motor. The screw is axially slidably connected to the bushing, and a second elastic element is provided between the screw and the bushing. When the second elastic element releases its elastic force, it drives the screw to slide and extend outward from the bushing.

[0012] Furthermore, both the movable clamp and the fixed clamp have an arc-shaped opening on their opposite sides.

[0013] Furthermore, a positioning element is installed on the side of the fixing clamp. The positioning element can cover the inlet between the moving clamp and the fixing clamp along the length direction of the spacer bar. When the positioning element is placed on the top of the bare wire, the arc on the moving clamp in the vertical state and the arc on one side of the fixing clamp can be aligned with the bare wire.

[0014] Furthermore, a stop is elastically slidably connected to the side of the movable clamp away from the fixed clamp. Both sides of the stop are rotatably connected to arc-shaped pressure rods. The top of the pressure rods is provided with jaws. A limit post is fixedly provided on the outer wall of the movable clamp. When the movable clamp is in a horizontal state, the pressure rods are engaged with the limit post through the jaws. When the movable clamp rotates to a vertical state, the limit post can move out of the jaws during the process of the movable clamp sliding horizontally towards the fixed clamp.

[0015] Furthermore, a connecting post is fixedly installed on the movable clamp, and the stop member slides through the connecting post. The other end of the connecting post is provided with a limiting block to restrict the stop member from disengaging from the connecting post. A fourth elastic member is provided between the connecting post and the stop member. When the fourth elastic member releases its elastic force, it drives the connecting post to adhere to the movable clamp.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the movable clamp of the locking mechanism cooperates with the fixed clamp by first deflecting and then translating. On the one hand, without increasing the size of the base and the drive mechanism, a larger inlet is provided between the movable clamp and the fixed clamp, which is conducive to lowering the locking mechanism to the outside of the bare wire. On the other hand, it is conducive to the cooperation between the screw and the screw hole, so that the movable clamp can be driven by power to move, so that the movable clamp can be closely attached to one side of the fixed clamp to provide a stable clamping force on the bare wire.

[0020] like Figures 1-10 As shown, a spacer bar for separating adjacent bare conductors includes a spacer bar 1 and locking mechanisms installed at both ends of the spacer bar 1. The spacer bar 1 is an insulator. The two locking mechanisms are used to lock two adjacent bare conductors respectively. Each locking mechanism includes a fixed clamp 2 and a movable clamp 3. The fixed clamp 2 is fixedly installed at the bottom of the base 13. An inlet is formed between the fixed clamp 2 and the movable clamp 3. An arc-shaped opening 6 is provided on the opposite side of the movable clamp 3 and the fixed clamp 2, and a rubber pad is provided on the circumferential surface of the arc-shaped opening 6. Specifically, a cylindrical component is fixedly installed on the side of the fixed clamp 2 away from the movable clamp 3. The end of the spacer bar 1 is inserted into the cylindrical component and fixedly connected to the cylindrical component by screws. During installation, the spacer bar 1 is hoisted above the bare conductors by a drone. During the process of the drone lowering the spacer bar 1, the bare conductors can enter between the movable clamp 3 and the fixed clamp 2 through the inlet and be clamped. Then, the driving mechanism causes the movable clamp 3 to press tightly against one side of the fixed clamp 2 to clamp the bare conductors.

[0021] In the prior art, the movable clip 3 is usually slid horizontally to stably fit against one side of the fixed clip 2. In this way, the external drive mechanism can also easily drive the movable clip 3 to move relative to the fixed clip 2. However, in actual installation, a large inlet needs to be formed between the movable clip 3 and the fixed clip 2 so that the drone can lower the locking mechanism to the outside of the bare wire. This results in the need to increase the size of the base 13 and the drive mechanism to accommodate the stroke of the movable clip 3, thereby increasing the overall weight and material usage of the locking mechanism. Based on this, the following embodiments make improvements to the configuration of the movable clip 3.

[0022] In this embodiment, the movable clamp 3 is movably disposed on one side of the base 13. The movable clamp 3 has a rotational stroke and a horizontal sliding stroke relative to the fixed clamp 2. During the rotational stroke, the movable clamp 3 has a horizontal state perpendicular to the fixed clamp 2 and a vertical state aligned with the fixed clamp 2. Figures 1-5As shown, when the movable clamp 3 is in a horizontal state, the inlet between the movable clamp 3 and the fixed clamp 2 is at its maximum value so that the locking mechanism can be lowered to the outside of the bare wire. When the movable clamp 3 is deflected downward to a vertical state, the movable clamp 3 and the fixed clamp 2 are aligned with each other, thus providing conditions for them to close together to clamp the bare wire.

[0023] Combination Figure 3 As shown, a screw 8 is rotatably mounted on the fixed clamp 2, and a screw hole 301 is provided on the movable clamp 3. When the movable clamp 3 rotates from a horizontal state to a vertical state, the screw hole 301 and the screw 8 are engaged together. The screw 8 rotates under the drive of the drive mechanism to engage with the screw hole 301, so that the movable clamp 3 can perform a horizontal sliding stroke. The movable clamp 3 slides closer to the fixed clamp 2, thereby clamping the bare wire.

[0024] Furthermore, a hinge block 302 is fixedly connected to the movable clamp 3, and a hinge seat 18 is slidably connected to the base 13. The hinge block 302 and the hinge seat 18 are rotatably connected via a connecting shaft 12. The connecting shaft 12 is fixedly connected to the hinge block 302 and rotatably connected to the hinge seat 18 via a bearing. A locking mechanism is provided between the hinge seat 18 and the base 13. The locking mechanism is configured to have two positions: at position one, in response to the horizontal state of the movable clamp 3, the hinge seat 18 is locked to the base 13; at position two, in response to the vertical state of the movable clamp 3, the hinge seat 18 is unlocked from the base 13. Then, the movable clamp 3 can be driven to move closer to or away from the fixed clamp 2 at the bottom of the base 13 through the cooperation of the screw 8 and the screw hole 301.

[0025] In summary, the movable clamp 3 in this solution uses a deflection-then-translation method to cooperate with the fixed clamp 2. On the one hand, without increasing the size of the base 13 and the drive mechanism, it provides a larger inlet between the movable clamp 3 and the fixed clamp 2, which is conducive to lowering the locking mechanism to the outside of the bare wire. On the other hand, it is conducive to the cooperation between the screw 8 and the screw hole 301, so that the movable clamp 3 can be moved by power drive, so that the movable clamp 3 can be closely attached to one side of the fixed clamp 2 to provide a stable clamping force on the bare wire.

[0026] like Figures 5-10As shown, the snap-fit ​​mechanism specifically includes a sliding frame 19 and a plug rod 1901 fixedly connected to the top of the sliding frame 19. The sliding frame 19 is rectangular and is vertically slidably connected to the slot on the side of the hinge seat 18. A first elastic element is provided between the sliding frame 19 and the hinge seat 18. When the first elastic element releases its elastic force, it drives the sliding frame 19 to move upward so that the plug rod 1901 passes through the through hole on the hinge seat 18 and is inserted into the slot 1302 on the base 13. The first elastic element can specifically be a support spring. The bottom of the support spring abuts against the hinge seat 18 and the top abuts against the sliding frame 19. The connecting shaft 12 passes through the interior of the sliding frame 19. A protrusion 1201 is provided on the peripheral side of the connecting shaft 12. The distance from the axis of the connecting shaft 12 to the side wall of the sliding frame 19 is greater than the distance from the axis of the connecting shaft 12 to the bottom surface of the sliding frame 19. When the moving clamp 3 is in the horizontal position, the protrusion 1201 faces the side of the sliding frame 19. During the process of the moving clamp 3 rotating from the horizontal state to the vertical state, the locking mechanism switches from position one to position two. The connecting shaft 12 drives the protrusion 1201 to rotate 90°, causing the protrusion 1201 to press the bottom surface of the sliding frame 19 and drive the sliding frame 19 to move downward relative to the hinge seat 18, thereby causing the insertion rod 1901 to move out of the slot 1302. The hinge seat 18 and the base 13 are unlocked. Subsequently, with the threaded engagement of the screw 8 and the screw hole 301, the hinge seat 18 and the moving clamp 3 can slide closer to the fixed clamp 2.

[0027] Combination Figures 3-5 As shown, a sleeve 15 is coaxially rotatably connected to at least one end of the connecting shaft 12. The sleeve 15 and the base 13 are only slidably fitted. Specifically, a through groove 1301 is provided on the base 13. The connecting shaft 12 passes through the through groove and can move along the length direction of the base 13 (parallel to the axis of the screw 8) within the through groove 1301. A square slider 1501 is fixedly provided at the end of the sleeve 15, and the slider 1501 slides within the through groove 1301 to prevent the sleeve 15 from rotating relative to the base 13. A third elastic element 14 is provided between the connecting shaft 12 and the sleeve 15. When the third elastic element 14 releases its elastic force, it drives the connecting shaft 12 to rotate relative to the sleeve 15, so that the moving clamp 3 rotates from a horizontal state to a vertical state. Specifically, the third elastic element 14 is a spiral spring or torsion spring that is movably sleeved on the connecting shaft 12. Its two ends are respectively connected to the inner wall of the sleeve 15 and the outer wall of the connecting shaft 12 to realize the elastic rotational connection between the connecting shaft 12 and the sleeve 15. Through this structure, when the rope 4 gradually loosens the moving clamp 3, the elastic force of the third elastic element 14 on the connecting shaft 12 can assist the moving clamp 3 to deflect from a horizontal state to a vertical state, and can also improve the gathering thrust of the moving clamp 3 on the bare wire.

[0028] As a preferred technical solution, the drive mechanism specifically includes a motor and a bushing 17 that is connected to the output end of the motor. The motor is embedded in the fixing clamp 2 or the base 13. The bushing 17 and the fixing clamp 2 are rotatably coupled through bearings. The screw 8 is axially slidably connected to the bushing 17. The section of the screw 8 inserted into the bushing 17 is a smooth part. The bushing 17 has a stepped hole along its axial direction, and the end of the screw 8 inserted into the stepped hole extends outward along the diameter direction of the screw 8 to form a flange to prevent the screw 8 from disengaging from the bushing 17. Figure 7 A key strip 1701 is integrally formed on the inner wall of the stepped hole, and a keyway 801 is provided on the outer circumferential surface of the screw 8 at the position of the smooth rod, which slides with the key strip 1701, so that the screw 8 and the bushing 17 are circumferentially fixed and axially slidingly engaged. A second elastic element 16 is provided between the screw 8 and the bushing 17 to enable the screw 8 and the bushing 17 to slide elastically in the axial direction. When the second elastic element 16 releases its elastic force, it drives the screw 8 to slide and extend outward from the bushing 17. The second elastic element 16 is specifically a limiting spring, which is located inside the bushing 17, with one end abutting against the bushing 17 and the other end abutting against the end of the screw 8. During the process of the movable clamp 3 rotating from a horizontal state to a vertical state, the movable clamp 3 will abut against the end of the screw 8 in the screw hole 301, causing the screw 8 to slide and retract into the bushing 17, and further compress the limiting spring. When the movable clamp 3 is completely in a vertical state, the screw 8 and the screw hole 301 become coaxial. The elastic force of the limiting spring is released, which squeezes the screw 8 into the screw hole 301, and the screw 8 and the screw hole 301 are connected together. Afterwards, only the screw 8 needs to be rotated to make the screw 8 and the screw hole 301 threadedly engage.

[0029] Combination Figure 4 As shown, a positioning element 7 is fixedly installed on at least one side of the fixed clamp 2. It is preferable that parallel and aligned positioning elements 7 are installed on both sides of the fixed clamp 2. It should be noted that the positioning element 7 can be a plate-shaped structure or a cylindrical structure. The positioning element 7 can cover the inlet between the moving clamp 3 and the fixed clamp 2 along the length direction of the spacer 1, so that during the process of the UAV lowering the spacer 1, the locking mechanism at both ends of the spacer 1 can fall onto the bare wire through the positioning element 7. Specifically, when the positioning element 7 falls on the top of the bare wire, the arc 6 on the vertical moving clamp 3 and the arc 6 on one side of the fixed clamp 2 can be aligned with the bare wire.

[0030] During use, the movable clamp 3 is suspended below the drone via rope 4. When the drone lifts the spacer 1, the tension of the movable clamp 3 on the rope 4 keeps it horizontal. When the drone lowers the locking mechanism onto the bare wire and the rope 4 gradually loosens the movable clamp 3, the movable clamp 3 gradually deflects downward and pushes the bare wire closer to the fixed clamp 2. When the movable clamp 3 rotates 90° and is completely vertical, the pressure of the protrusion 1201 on the sliding frame 19 causes the sliding frame 19 to move downward, thus causing one end of the insertion rod 1901 to move from the base. When the slot 1302 on 13 is removed, the hinge seat 18 and the base 13 are unlocked. During the process of the moving clamp 3 deflecting downward to a vertical state, the moving clamp 3 can squeeze the screw 8, so that the screw 8 overcomes the pressure of the second elastic member 16 and is further inserted into the bushing 17. When the moving clamp 3 deflects to a fully vertical state, the screw 8 can be aligned with the screw hole 301 and the screw 8 pops out and is inserted into the screw hole 301. During the process of the motor driving the bushing 17 and the screw 8 to rotate, the moving clamp 3 can be driven to gradually approach the fixed clamp 2 to clamp the bare wire at the bottom of the positioning member 7.

[0031] Combination Figures 3-5 , Figure 9 As shown, in order to confine the bare wire to the inlet, a stop 11 is elastically slidably connected on the side of the movable clamp 3 away from the fixed clamp 2, combined with... Figure 3 As shown, a connecting post 9 is fixedly installed on the movable clamp 3. Its end has a limiting block to restrict the stop 11 from disengaging. The connecting post 9 has a T-shaped cross-section along its axial direction. The connecting post 9 passes through the stop 11 and slides with it. A spring is provided between the end of the connecting post 9 and the stop 11 to achieve an elastic fit between the stop 11 and the movable clamp 3. When the positioning member 7 falls onto the bare conductor, the stop 11 can be positioned on one side of the bare conductor to limit the conductor at the inlet. Both sides of the stop 11 are rotatably connected to arc-shaped pressure rods 10. Specifically, the bottom end of the pressure rod 10 is rotatably connected to the stop 11 via a pin, while the top end of the pressure rod 10 is provided with jaws. Figure 9 As can be seen, a limiting post 20 is fixedly installed on the outer wall of the movable clamp 3. When the movable clamp 3 is in a horizontal state, the limiting post 20 is inside the jaws, thereby limiting the pressure rod 10. Figure 3 , Figure 6As shown, during the process of the movable clamp 3 rotating 90° and gradually reaching a vertical state, the arc-shaped pressure rod 10 facilitates the application of a horizontal force to the bare wire, thereby causing the bare wire to gradually approach the fixed clamp 2 along the positioning member 7. Furthermore, during the process of the stop member 11 rotating to the position below the fixed clamp 2, the pressure of the bottom end of the fixed clamp 2 on the stop member 11 causes the stop member 11 to move outward relative to the movable clamp 3, thereby causing the jaws to disengage from the limiting post 20. In this state, the pressure rod 10 can rotate relative to the movable clamp 3, so that during the process of the movable clamp 3 being driven to move by the screw 8 and the screw hole 301, the bare wire can enter the arc opening 6 of the movable clamp 3. Thus, during the process of the movable clamp 3 being attached to one side of the fixed clamp 2, the bare wire and the pressure rod 10 will not interfere with each other.

[0032] like Figure 1 As shown, the motor can be installed at the fixed clamp 2, and a power supply 5 electrically connected to the motor is installed above the base 13. Specifically, the power supply 5 and the base 13 can be fixedly connected or detachably connected, allowing the drone to either lift the power supply 5 away or leave it on the base 13 after installing the spacer 1. The power supply 5 and the drone, as well as the moving clamp 3 and the drone, can be connected by ropes 4. It should be noted that lifting rings can be installed on the housing of the power supply 5 and the moving clamp 3, and the end of the rope 4 is connected to the lifting rings via hooks, thus facilitating the connection between the rope 4 and the power supply. 5. Separation of the moving clamp 3, or, the rope 4 is fixedly connected to the lifting ring. In this method, a box is installed on the rope 4, so that the rope 4 passes through the box. The rope 4 near the drone is fixedly engaged with the box, while the rope 4 near the base 13 can slide relative to the box. A small electric cutting device is installed on the box. In actual use, the staff can remotely control the electric cutting device through a signal connection, so that the electric cutting device can cut the rope 4. The electric cutting device is a common device on the market, and its structure and working principle will not be described in detail here.

[0033] Regarding the specific installation method of the hinge seat 18, a slot is opened on one side of the bottom of the base 13, and the hinge seat 18 is installed in the slot. The aforementioned slot 1302 is opened on the top wall of the slot, combined with... Figures 8-10 As shown, a connector 1801 with the same structure as the connecting post 9 is fixedly installed on the hinge base 18. A connecting hole is provided at the inner end face of the slot. The connecting hole is stepped, and the connector 1801 slides within the connecting hole. In the initial state, the moving clamp 3 is in a horizontal state, and the end of the connector 1801 is fitted with the end of the connecting hole to prevent the connector 1801 from moving outward relative to the base 13. Figure 9As shown, the side of the hinge base 18 away from the movable clamp 3 and the top surface of the hinge base 18 are both provided as abutment portions 1802, so that the movable clamp 3 can contact the abutment portion 1802 at the top of the hinge base 18 when it is in a horizontal state, and can contact the abutment portion 1802 on the side of the hinge base 18 when it is in a vertical state, so that the movable clamp 3 can be stably kept in a horizontal or vertical state. It should be noted that the side edge of the bottom outer side of the fixed clamp 2 can be chamfered to avoid interference with the fixed clamp 2 when the movable clamp 3 is deflected downwards, and to facilitate the contact between the bottom surface of the fixed clamp 2 and the movable clamp 3 when it is rotated to a vertical state.

[0034] In the above technical solution, it should be noted that the moving direction between the movable clamp 3 and the fixed clamp 2 in the vertical state, the sliding direction between the sleeve 15 and the base 13, the sliding direction between the sleeve 15 and the screw 8, and the sliding direction between the movable clamp 3 and the stop 11 in the horizontal state are all the same as the axial direction of the screw 8.

[0035] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.

4. The spacer bar for separating adjacent bare conductors according to claim 3, characterized in that: A sleeve (15) is coaxially rotatably connected to the connecting shaft (12). The sleeve (15) and the base (13) are in sliding fit. A third elastic element (14) is provided between the connecting shaft (12) and the sleeve (15). When the third elastic element (14) releases its elastic force, it drives the connecting shaft (12) to rotate relative to the sleeve (15), so that the moving clamp (3) rotates from a horizontal state to a vertical state.

5. The spacer bar for separating adjacent bare conductors according to claim 4, characterized in that: The third elastic element (14) includes a spiral spring or a torsion spring, one end of which is connected to the sleeve and the other end of which is connected to the connecting shaft.

6. The spacer bar for separating adjacent bare conductors according to claim 1, characterized in that: The driving mechanism includes a motor embedded in the fixed clamp (2) and a bushing (17) that is connected to the output end of the motor. The screw (8) is axially slidably connected to the bushing (17). A second elastic element is provided between the screw (8) and the bushing (17). When the second elastic element releases its elastic force, it drives the screw (8) to slide and extend outward to the bushing (17).

7. The spacer bar for separating adjacent bare conductors according to claim 1, characterized in that: The movable clamp (3) and the fixed clamp (2) are both provided with an arc-shaped opening (6) on the opposite side.

8. The spacer bar for separating adjacent bare conductors according to claim 7, characterized in that: The side of the fixed clamp (2) is equipped with a positioning member (7). The positioning member (7) can cover the inlet between the moving clamp (3) and the fixed clamp (2) along the length direction of the spacer (1). When the positioning member (7) falls on the top of the bare wire, the arc opening (6) on the moving clamp (3) in the vertical state and the arc opening (6) on one side of the fixed clamp (2) can be aligned with the bare wire.

9. The spacer bar for separating adjacent bare conductors according to claim 1, characterized in that: The movable clamp (3) is elastically slidably connected to a stop (11) on the side away from the fixed clamp (2). Both sides of the stop (11) are rotatably connected to an arc-shaped pressure rod (10). The top of the pressure rod (10) is provided with a jaw. A limit post (20) is fixedly provided on the outer wall of the movable clamp (3). When the movable clamp (3) is in a horizontal state, the pressure rod (10) is engaged with the limit post (20) through the jaw. When the movable clamp (3) is rotated to a vertical state, the limit post (20) can move out of the jaw during the process of the movable clamp (3) sliding horizontally close to the fixed clamp (2).

10. The spacer bar for separating adjacent bare conductors according to claim 9, characterized in that: A connecting column (9) is fixedly installed on the movable clamp (3). The stop (11) slides through the connecting column (9). The other end of the connecting column (9) is provided with a limiting block to prevent the stop (11) from disengaging from the connecting column (9). A fourth elastic element is provided between the connecting column (9) and the stop (11). When the fourth elastic element releases its elastic force, it drives the connecting column (9) to adhere to the movable clamp (3).
