Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution equipment technology, and in particular to a primary and secondary integrated pole-mounted circuit breaker that is easy to connect. Background Technology
[0002] Primary and secondary integrated pole-mounted circuit breakers are typically installed on the poles of power distribution lines. Their primary side is used to connect to the power distribution line, while the secondary side is used for sampling, control, and communication functions. During maintenance, testing, temporary connections, or emergency handling, it is sometimes necessary to connect temporary conductors to the primary wiring position of the circuit breaker for testing, connection, or auxiliary operations.
[0003] Existing primary wiring structures typically use bolts, nuts, washers, or pressure plates to secure the wires. While this type of structure is suitable for long-term fixed wiring, temporary wiring on poles usually requires workers to loosen or even remove some fasteners before placing the temporary wires in the wiring location and retightening them. Due to the high working position and limited operating space, small parts such as bolts and washers are prone to falling off during disassembly and assembly, affecting wiring efficiency and increasing operational inconvenience.
[0004] Meanwhile, the conductive connection of the temporary wire needs to be reliably clamped after connection. If only a rigid crimping structure is used, the clamping state is easily unstable due to differences in wire specifications, placement deviations, or external vibrations. If a protective structure is set up, it usually only serves as a shield and cannot continuously maintain the clamping state. Therefore, the existing structure still has problems such as cumbersome operation, easy fastener loss, difficulty in compensating for and maintaining the clamping state, and insufficient protection of the connection points when making temporary wiring. Utility Model Content
[0005] The purpose of this utility model is to provide a primary and secondary integrated pole-mounted circuit breaker that is convenient for wiring, so as to solve the problems of existing pole-mounted circuit breakers requiring the removal and installation of fasteners during temporary wiring, inconvenient operation, easy falling off of fasteners, and difficulty in maintaining the compressed state of temporary wires.
[0006] To achieve the above objectives, this utility model provides a convenient primary and secondary integrated pole-mounted circuit breaker, including an insulating column and a conductive connection seat disposed on one side of the insulating column. The conductive connection seat is provided with a wiring mechanism, which has a base fixedly connected and electrically connected to the conductive connection seat. A groove is formed on the base for placing the conductive connection portion of a temporary conductor. A rotating shaft is fixedly disposed on the base, and a protective shell is rotatably disposed on the rotating shaft. The protective shell can be opened or closed relative to the base. A pressure plate is disposed between the protective shell and the base, and the pressure plate is located above the groove. A first spring connects the protective shell and the pressure plate. When the protective shell is closed, the first spring causes the pressure plate to press against the conductive connection portion of the temporary conductor towards the groove. A locking mechanism is disposed between the protective shell and the base to keep the protective shell in a closed state.
[0007] Preferably, the pressure plate is provided with a pressure groove corresponding to the wire groove, and when the protective shell is closed, the wire groove and the pressure groove together clamp the conductive connection part of the temporary wire.
[0008] Preferably, the pressure plate is in the shape of a bent sheet, with one end of the pressure plate near the rotating shaft rotatably mounted on the rotating shaft, and the other end of the pressure plate away from the rotating shaft located above the wire groove.
[0009] Preferably, the locking mechanism has a fixing member fixed to the protective shell, the fixing member is provided with a pawl, and a ratchet is fixedly provided on the rotating shaft. The pawl and the ratchet cooperate to restrict the protective shell from rotating in the opening direction.
[0010] Preferably, the ratchet is sleeved and fixed to the rotating shaft via a spline.
[0011] Preferably, a protective plate is provided on the outside of the fixing member, the pawl is located between the fixing member and the protective plate, and a second spring is provided between the pawl and the protective plate. The second spring is used to drive the pawl to remain engaged with the ratchet.
[0012] Preferably, the pawl is provided with a pull pin, which is used to drive the pawl to overcome the elastic force of the second spring and disengage from the ratchet, so as to release the locking mechanism from locking the protective shell.
[0013] Compared with the prior art, the advantages of this utility model are as follows: This utility model sets up a wiring mechanism on the conductive connector, allowing the conductive connection part of the temporary wire to be placed in the wire groove. When the protective shell is closed, the first spring pushes the pressure plate to press the temporary wire, thus forming an electrical connection between the temporary wire and the base. This structure eliminates the need to disassemble bolts, nuts, washers, and other fasteners each time a temporary connection is made, reducing the risk of fasteners falling off during pole work.
[0014] Meanwhile, the first spring provides elastic clamping force to the pressure plate, enabling the pressure plate to compensate for the temporary conductor. This helps to adapt to differences in the placement or specifications of the temporary conductor, improving the clamping stability of the temporary connection. After the protective shell is closed, it remains in the closed state through a locking mechanism, allowing the pressure plate to continuously clamp the temporary conductor and provide external protection for the connection location. This balances wiring convenience, connection reliability, and protective effect.
[0015] Furthermore, the locking mechanism employs a pawl and a fixed ratchet for locking. The ratchet is fixedly mounted on the rotating shaft, and the pawl moves with the protective shell. When the protective shell is closed, the pawl slides along the teeth of the ratchet and enters the locked position. When the protective shell tends to open in the opposite direction, the pawl is stopped by the teeth of the ratchet, thus limiting the opening of the protective shell and keeping it closed, ensuring the continuous pressing action of the first spring on the pressure plate.

[0023] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application.
[0024] like Figure 1 As shown, this embodiment of a convenient primary and secondary integrated pole-mounted circuit breaker includes an insulating column 1, a conductive connector 2, and a wiring mechanism 3. The insulating column 1 forms an insulating support structure for the primary side of the circuit breaker. The conductive connector 2 is disposed on one side of the insulating column 1 and connected to the primary conductive circuit of the circuit breaker. The wiring mechanism 3 is disposed on the conductive connector 2 and is used to connect temporary conductors in operation scenarios such as maintenance, testing, temporary connection, or temporary lead-in. Since pole-mounted circuit breakers are usually installed on poles or supports, it is not advisable for workers to frequently disassemble small fasteners such as screws, nuts, and washers when performing temporary wiring at heights. Therefore, this embodiment uses a wiring mechanism 3 that can close and tighten, in conjunction with a locking mechanism 4, to allow temporary conductors to be tightened and fixed without disassembling the crimping screws, nuts, or washers, thereby reducing the risk of parts falling during high-altitude operations and improving the convenience of temporary wiring operations.
[0025] like Figure 2 and Figure 3 As shown, the wiring mechanism 3 is located on the outside of the conductive connector 2. The wiring mechanism 3 has a base 32, which is fixed to the conductive connector 2 and forms an electrical connection with it. The base 32 is a metal conductive component and can be connected to the conductive connector 2 by means of screws, riveting, welding, crimping, or integral molding. In this embodiment, the base 32 is preferably fixedly installed at the end of the conductive connector 2, making the base 32 an external conductive wiring part on the conductive connector 2. When a temporary wire is connected, the conductive connection part of the temporary wire contacts the base 32, and the current can sequentially pass through the conductive connection part of the temporary wire, the base 32, and the conductive connector 2 into the primary conductive circuit of the circuit breaker.
[0026] A wire groove 321 is provided on the base 32 to accommodate the conductive connection part of the temporary wire. The conductive connection part of the temporary wire can be the exposed metal core after the insulation layer has been removed from the end of the temporary wire, or it can be a wire lug, conductive end, or other metal connection part that can form conductive contact with the base 32 and is pre-crimped to the end of the temporary wire. The wire groove 321 is located on the upper surface of the base 32 and extends along the insertion direction of the temporary wire. To prevent the temporary wire from slipping laterally after insertion, the wire groove 321 can be configured as an arc-shaped groove, a semi-circular groove, or a V-shaped groove. In this embodiment, the wire groove 321 is preferably a groove-shaped structure that is recessed into the base 32, so that the conductive connection part of the temporary wire can be stably placed within the wire groove 321. Since the base 32 is a metal conductive component, the groove wall of the wire groove 321 can serve as a conductive contact surface. After the pressure plate 33 presses the temporary wire, the conductive connection part of the temporary wire can fit tightly against the conductive contact surface of the wire groove 321.
[0027] A rotating shaft 47 is fixedly mounted on the base 32, and the rotating shaft 47 remains fixed relative to the base 32. The protective shell 31 is rotatably mounted on the rotating shaft 47, and the protective shell 31 can rotate about the rotating shaft 47 relative to the base 32 between an open state and a closed state. Figure 3 The diagram shows the state when the protective housing 31 is open, at which point the wire groove 321 on the base 32 is exposed, and the operator can place the conductive connection part of the temporary wire into the wire groove 321. Figure 2 The diagram shows the structure when the wiring mechanism 3 is in the closed state. At this time, the protective shell 31 covers the outside of the base 32 and the wire groove 321, which can shield and protect the wiring position.
[0028] The protective housing 31 is preferably made of an insulating material, such as insulating plastic, insulating composite material, or other materials with sufficient mechanical strength and insulating properties. The protective housing 31 can be shaped like a cover or a lid, with an internal receiving space to accommodate the pressure plate 33, the first spring 331, and the portion of the temporary wire located near the wire groove 321 when closed. A clearance opening can be provided on the side of the protective housing 31 for the temporary wire to extend, allowing the protective housing 31 to remain closed even after the temporary wire is inserted into the wire groove 321. This clearance opening can be U-shaped, arc-shaped, or oblong, as long as it allows the temporary wire to extend from within the protective housing 31. With this structure, the protective housing 31 not only shields the base 32 when no wiring is being done, but also remains closed after the temporary wire is inserted, preventing the wiring location from being exposed for extended periods.
[0029] A pressure plate 33 is disposed between the protective housing 31 and the base 32, and is used to press the temporary conductive connection of the wire placed in the wire trough 321 when the protective housing 31 is closed. Figure 3 and Figure 4As shown, the pressure plate 33 is located above the wire groove 321. One end of the pressure plate 33 near the rotating shaft 47 is rotatably mounted on the rotating shaft 47, and the other end of the pressure plate 33 away from the rotating shaft 47 is located above the wire groove 321 and forms a wire pressing end. A first spring 331 is connected between the protective shell 31 and the pressure plate 33. When the protective shell 31 is closed, the first spring 331 applies an elastic force to the pressure plate 33 in the direction of the wire groove 321, so that the wire pressing end of the pressure plate 33 can press the conductive connection part of the temporary wire.
[0030] The pressure plate 33 can be a bent sheet structure, with one end near the rotating shaft 47 forming a rotating connection end and the other end away from the rotating shaft 47 forming a wire pressing end. The wire pressing end of the pressure plate 33 is located above the wire groove 321. When the conductive connection part of the temporary wire is placed in the wire groove 321, the protective shell 31 closes, and the first spring 331 pushes the pressure plate 33 to move towards the wire groove 321, so that the pressure plate 33 presses against the conductive connection part of the temporary wire from above. In this way, the conductive connection part of the temporary wire is pressed tightly into the wire groove 321 and forms a reliable metal contact with the base 32.
[0031] Combination Figure 4 As shown, the pressure plate 33 can be provided with a mating groove or a wire-pressing recess corresponding to the wire groove 321, so that when the pressure plate 33 is pressed down, it can form a relatively stable clamping space together with the wire groove 321. After the conductive connection part of the temporary wire is placed into the wire groove 321, the pressure plate 33 presses the conductive connection part from above, and the wire groove 321 supports the conductive connection part from below, thereby forming an upper and lower clamping relationship. Since the base 32 is a metal conductive part, the conductive connection part of the temporary wire can form a stable contact with the base 32 after being pressed, thereby achieving a reliable electrical connection. Compared with the direct pressing of ordinary screws, the pressure plate 33 in this embodiment does not require the operator to disassemble and reinstall it. Instead, it is pressed by the elastic force generated by the first spring 331 when the protective shell 31 is closed, reducing the operation of disassembling and assembling small parts when working at heights.
[0032] A first spring 331 is connected between the protective shell 31 and the pressure plate 33. Specifically, one end of the first spring 331 is connected to the protective shell 31, and the other end is connected to the pressure plate 33. When the protective shell 31 is closed, the first spring 331, affected by the change in the relative position between the protective shell 31 and the pressure plate 33, applies an elastic force to the pressure plate 33 in the direction of the wire groove 321, causing the pressure plate 33 to continuously press the conductive connection part of the temporary wire. The first spring 331 ensures that the pressure of the pressure plate 33 on the temporary wire is not completely rigid, but has a certain elastic compensation capability. When there are differences in the wire diameter of the temporary wire, differences in the thickness of the conductive connection part, or slight deviations in the position of the wire placed in the wire groove 321, the first spring 331 can compensate for the pressing stroke through elastic deformation, so that the pressure plate 33 can still form a stable pressing on the temporary wire.
[0033] In this embodiment, the first spring 331 can be a compression spring, a tension spring, or a torsion spring. Preferably, the first spring 331 is disposed between the inner side of the protective shell 31 and the pressure plate 33, so that it will not be exposed and affect the protective effect, and can continue to apply force to the pressure plate 33 after the protective shell 31 is closed. The number of first springs 331 can be one or more. When there are multiple first springs 331, the multiple first springs 331 can be spaced apart along the width direction of the pressure plate 33 to make the pressure plate 33 more evenly stressed. The figure only illustrates the arrangement of the first springs 331. In actual manufacturing, the spring stiffness, length, and installation position can be adjusted according to the specifications of the temporary wire and the clamping force requirements.
[0034] To ensure that the protective housing 31 remains closed after being closed, this embodiment also includes a locking mechanism 4. The locking mechanism 4 is positioned between the protective housing 31 and the base 32, and is used to prevent the protective housing 31 from opening in the reverse direction after it is closed. Since the first spring 331 exerts an elastic force on the pressure plate 33 after the protective housing 31 is closed, and the temporary wire may also exert a reaction force on the pressure plate 33 due to its own elasticity, external tension, or vibration, if the protective housing 31 cannot be reliably locked, the continuous pressing effect of the pressure plate 33 will be affected. Therefore, the locking mechanism 4 is an important structure for maintaining the stable pressing of the wiring mechanism 3.
[0035] like Figure 5 As shown, the locking mechanism 4 in this embodiment adopts a ratchet and pawl locking structure. The locking mechanism 4 includes a fixing member 41, a ratchet 42, a pawl 43, a pull pin 44, a second spring 45, and a guard plate 46. The fixing member 41 is fixed to the protective shell 31, and the fixing member 41 can be connected to the protective shell 31 by screws, rivets, or integral molding. The ratchet 42 is disposed on the rotating shaft 47 and fixedly connected to the rotating shaft 47. Since the rotating shaft 47 is fixedly disposed on the base 32, the ratchet 42 remains fixed relative to the base 32. The pawl 43 is disposed on the fixing member 41, and when the fixing member 41 rotates with the protective shell 31 around the rotating shaft 47, the pawl 43 also moves with the protective shell 31 around the rotating shaft 47.
[0036] The ratchet 42 is preferably splined and fixed to the shaft 47. The spline connection improves the connection stability between the ratchet 42 and the shaft 47, preventing circumferential sliding of the ratchet 42 relative to the shaft 47, thus allowing the ratchet 42 to function as a stable locking mechanism. Of course, in other embodiments, the ratchet 42 can also be connected to the shaft 47 via a key connection, square shaft connection, pin connection, interference fit, or integral molding, as long as the ratchet 42 remains fixed relative to the shaft 47.
[0037] Pawl 43 is mounted on the fixing member 41 and can engage with ratchet 42. One end of pawl 43 can be mounted on the fixing member 41 via a pin or rotatable connection, while the other end forms a locking end that engages with the teeth of ratchet 42. When the protective shell 31 rotates in the closing direction, the fixing member 41 drives pawl 43 to move around the rotating shaft 47. Pawl 43 slides along the tooth surface of ratchet 42 and makes clearance, allowing the protective shell 31 to close smoothly. When the protective shell 31 is closed, pawl 43 engages with the teeth of ratchet 42 under the action of the second spring 45. When the protective shell 31 has a tendency to rotate in the opposite direction of opening, pawl 43 is stopped by the teeth of ratchet 42, thereby restricting the rotation of the protective shell 31 in the opening direction. In this way, the protective shell 31 is locked by the locking mechanism 4 after closing and cannot be opened by itself due to the reaction force of the first spring 331 or the elastic rebound of the temporary wire.
[0038] The guard plate 46 is located on the outside of the fixing member 41, and the pawl 43 can be located between the fixing member 41 and the guard plate 46. The guard plate 46 provides external protection for components such as the pawl 43 and the second spring 45, preventing them from being hit by foreign objects or interfered with by debris. The second spring 45 is located between the pawl 43 and the guard plate 46, and is used to drive the pawl 43 to maintain an engaged state toward the ratchet 42. That is, without external force operating the pull pin 44, the second spring 45 will make the pawl 43 always tend to engage with the ratchet 42, thereby ensuring the locking reliability of the locking mechanism 4.
[0039] A pull pin 44 is mounted on the pawl 43 to disengage the pawl 43 from the ratchet 42. When the protective housing 31 needs to be opened to remove temporary wires or rewire, the operator pulls the pull pin 44. The pull pin 44 causes the pawl 43 to overcome the elastic force of the second spring 45, disengaging the pawl 43 from the ratchet 42. After the pawl 43 disengages from the ratchet 42, the protective housing 31 can rotate around the pivot 47 in the opening direction. As the protective housing 31 opens, the pressure plate 33 gradually moves away from the wire groove 321, allowing the conductive connection of the temporary wire to be removed from the wire groove 321. After releasing the pull pin 44, the second spring 45 pushes the pawl 43 back towards the ratchet 42, preparing for the next locking action.
[0040] The wiring process in this embodiment is as follows. Before performing temporary wiring, the operator shall operate under conditions that meet the requirements for electrical safety. First, the operator shall disengage the pawl 43 from the ratchet 42 by pulling the pin 44, or directly open the protective housing 31 if it is not locked, so that the protective housing 31 is in the locked position. Figure 3 The diagram shows the open state. At this time, the wire groove 321 on the base 32 is exposed, and the pressure plate 33 is away from the wire groove 321. The operator can insert one end of the temporary wire's conductive connection into the wire groove 321. Because the wire groove 321 has a certain limiting function, the conductive connection of the temporary wire is not easily allowed to slide left or right after being inserted.
[0041] Subsequently, the operator rotates the protective housing 31 in the closing direction. During the closing process of the protective housing 31, the first spring 331 gradually receives force and generates an elastic clamping force on the pressure plate 33, causing the pressure plate 33 to press the conductive connection part of the temporary wire towards the wire groove 321. When the protective housing 31 is closed in place, the pressure plate 33, under the action of the first spring 331, presses the conductive connection part of the temporary wire, making the conductive connection part of the temporary wire tightly adhere to the conductive contact surface of the wire groove 321 on the base 32. At this time, the temporary wire forms an electrical connection with the base 32, and the base 32 is in turn electrically connected to the conductive connection seat 2, thereby realizing the connection between the temporary wire and the primary conductive circuit of the circuit breaker.
[0042] During the closing process of the protective housing 31, the fixing member 41 moves around the rotating shaft 47 with the protective housing 31, and drives the pawl 43 to move along the ratchet 42 fixed on the rotating shaft 47. The pawl 43 is displaced by the teeth of the ratchet 42 and passes over them one tooth at a time. When the protective housing 31 is closed, the pawl 43 is engaged with the teeth of the ratchet 42 by the action of the second spring 45, preventing the protective housing 31 from rotating in the opposite direction of opening. Thus, the protective housing 31 is kept in the closed state, and the first spring 331 can continuously apply elastic clamping force to the pressure plate 33, which continuously presses the conductive connection of the temporary wire. Since this clamping process does not require the operator to remove screws, nuts or washers, it can effectively reduce the risk of parts falling when working at heights.
[0043] When it is necessary to remove the temporary wire, the operator operates the pull pin 44 to disengage the pawl 43 from the ratchet 42, thus releasing the locking mechanism 4. Then, the protective housing 31 is rotated in the opening direction. After the protective housing 31 is opened, the pressure of the first spring 331 on the pressure plate 33 is released, and the pressure plate 33 leaves the wire groove 321, allowing the conductive connection of the temporary wire to be removed from the wire groove 321. Throughout the entire wire removal process, it is also unnecessary to remove the crimping screws or small fasteners, making the wire removal operation more convenient.
[0044] The beneficial effects of this embodiment are as follows: First, the wiring mechanism 3 is set on the conductive connector 2. The temporary wire only needs to be placed in the wire groove 321 of the base 32. By closing the protective shell 31, the pressure plate 33 can press the temporary wire tightly, avoiding the need to disassemble bolts, nuts, washers, or pressure plates in traditional temporary wiring, thus reducing the risk of parts falling during high-altitude operations. Second, a first spring 331 is provided between the pressure plate 33 and the protective shell 31, so that the pressure plate 33 forms an elastic compensation pressure on the temporary wire, which can adapt to slight differences in the size, placement position, or contact state of the conductive connection part of the temporary wire, improving the pressure stability. Third, the locking mechanism 4 restricts the reverse opening of the protective shell 31 after it is closed, so that the pressing action of the first spring 331 can be maintained continuously, avoiding the protective shell 31 from loosening due to vibration, wire rebound, or external force. Fourth, after the protective shell 31 is closed, it covers the outside of the base 32, wire groove 321, and pressure plate 33, forming a shielding protection for the wiring part, reducing accidental contact, foreign object entry, or external environmental influence caused by exposed wiring parts.
[0045] In summary, this embodiment integrates the placement, clamping, locking, and protection of temporary wires into a single wiring mechanism 3 through the cooperation of the base 32, wire groove 321, protective shell 31, pressure plate 33, first spring 331, and locking mechanism 4. Its core principle is to utilize the closing action of the protective shell 31 in conjunction with the first spring 331 to push the pressure plate 33 to clamp the temporary wires, while the locking mechanism 4 maintains the protective shell 31 in a closed state, thereby achieving a comprehensive effect of convenient wiring, preventing component loss, continuous clamping, and external protection.
[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
