Description

Technical Field

[0001] This invention relates to the field of electrical connection technology, specifically to a quick-connect mechanism for terminal blocks. Background Technology

[0002] A metering box is a comprehensive set of metering instruments and auxiliary equipment necessary for measuring electrical energy. It includes electricity meters, voltage and current transformers and their secondary circuits, electricity metering panels, cabinets, and boxes, etc., which house measuring instruments and meters. The secondary outputs of the combined transformers are connected to the terminals of these instruments and meters in a prescribed manner. For more promising modular metering boxes, the box is deconstructed into independent functional units such as a back panel, cable connectors, quick-connect switch connectors, and meter bases. Each module is required to have standard electrical and mechanical interfaces, supporting quick plug-and-play installation and flexible combination in the field.

[0003] However, the current method of connecting the various components inside the metering box to power each other is to use bolts to tighten and fix the wires or to insert bolts into the holes of the terminals and tighten the terminals with threads. In practice, both of these connection methods require the operator to use a screwdriver to tighten the bolts, which is inconvenient and time-consuming. Moreover, after multiple disassemblies, the threaded fixation may become loose, which can easily lead to poor contact.

[0004] For example, the patent disclosed in CN118554191B relates to the field of electrical connector technology. It includes a terminal block, a terminal port, and a conductive sheet. The conductive sheet enables continuous power transmission on the wire. It also includes an abutment component disposed inside the terminal block, an operating plate disposed on the top of the terminal block, and a wire clamping component disposed at the bottom of the operating plate. The wire clamping component is disposed directly above the conductive sheet and is used to fix and clamp the wire conductor above the conductive sheet.

[0005] The aforementioned existing technology has solved the problems of inconvenience and time-consuming operation of traditional threaded fixed connection methods. However, the elastic clamping fixing method is difficult to guarantee that the terminal will not loosen under long-term operation, and loosening will still lead to poor wire contact. Summary of the Invention

[0006] The purpose of this invention is to provide a quick connection mechanism for terminals to solve the problem that the elastic clamping fixing method in the prior art is difficult to guarantee that the terminals will not loosen during long-term operation, and that loosening will still lead to poor wire contact.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a quick connection mechanism for terminals, comprising a connector with a flat ring and a terminal connection portion disposed inside a component. The terminal connection portion includes a base, conductive arc petals, a slide rod, and auxiliary components. The base is elastically slidably connected to the component. There are two conductive arc petals, symmetrically slidably connected to the base. The two conductive arc petals have an energized position for clamping the connector during their sliding stroke. The slide rod is elastically slidably connected to the base. One end of the slide rod is rotatably connected to two connecting rods. The other ends of the two connecting rods are slidably connected to the two conductive arc petals one-to-one. The auxiliary components include a sliding pin slidably connected to the component. When the connector is inserted into the mounting port of the component, its end abuts against and pushes the slide rod. The slide rod drives the two conductive arc petals to slide to the energized position through the two connecting rods and is locked by a locking member disposed on the base. The sliding pin is inserted into the flat ring of the connector to lock the connector and the base inside the component.

[0008] Furthermore, the locking component includes two locking pins slidably connected to the base, and two conductive arc lobes are respectively provided with locking holes adapted to the locking pins.

[0009] Furthermore, a first spring is provided between the locking pin and the base, with one end of the first spring fixedly connected to the locking pin and the other end fixedly connected to the base.

[0010] Furthermore, a sliding column is fixedly connected to the component, and the base is slidably connected to the component through the sliding column.

[0011] Furthermore, a second spring is fitted onto the sliding column, with one end of the second spring fixedly connected to the sliding column and the other end fixedly connected to the base.

[0012] Furthermore, the diameter of the sliding pin is adapted to the hole of the connector. When the conductive arc flap clamps the connector and the base elastically resets, the sliding pin is aligned with the hole of the connector.

[0013] Furthermore, a third spring is provided between the sliding pin and the component. One end of the third spring is fixedly connected to the sliding pin, and the other end is fixedly connected to the component.

[0014] Furthermore, the auxiliary components also include a first card plate and a first card block. The first card plate is fixed on the base, and the first card block is fixed on the sliding pin. When the electrical connector is not plugged in, the side of the first card plate facing away from the base abuts against the side of the first card block facing the base.

[0015] Furthermore, an unlocking rod is slidably connected to the side of the component, and a transmission rod is rotatably connected to the end of the unlocking rod that is embedded in the component. The end of the transmission rod away from the unlocking rod is rotatably connected to a sliding pin.

[0016] Furthermore, the locking pin is slidably connected to the slide column, and a second locking block is fixedly connected to the end of the locking pin near the slide column. A second locking plate is fixedly connected to the end of the slide column near the locking pin. When the base slides away from the slide column, the second locking plate and the second locking block finally abut against each other and push the second locking block and the locking pin to slide out of the lock hole.

[0017] In the above technical solution, the present invention provides a quick connection mechanism for a connector. The entire installation process only requires pushing the connector towards the inside of the component until the conductive arc petals clamp the connector. Then, slightly pull the connector in the opposite direction and release the connector to complete the installation. Compared with the prior art, the installation method of the connector in the present invention saves installation time, and the installation method is simple and convenient with just one push and one pull. Finally, the connector is locked in a fixed lock. The two conductive arc petals can achieve contact with the flat annular surface of the connector through their own clamping groove design, ensuring the stability of the power connection and avoiding poor contact that is easy to occur with elastic clamping.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Please see Figures 1-9 This invention provides a quick-connect mechanism for terminal blocks, including a connector 1 and a terminal connection part 2 disposed inside a component 11. The terminal connection part 2 includes a base 3, conductive arc petals 4, a slide rod 5, and auxiliary components 7. The base 3 is elastically slidably connected to the component 11. There are two conductive arc petals 4, which are symmetrically slidably connected to the base 3. The two conductive arc petals 4 have a energized position for clamping the connector 1 during their sliding stroke. The slide rod 5 is elastically slidably connected to the base 3, and the end of the slide rod 5 located inside the base 3 is rotatably connected to... There are two connecting rods 51, and the other ends of the two connecting rods 51 are slidably connected to the two conductive arc petals 4 one-to-one. The auxiliary component 7 includes a sliding pin 71 that is elastically slidably connected to the component 11. When the connector 1 is inserted into the mounting port of the component 11, the end of the connector 1 abuts against the sliding rod 5 and pushes the sliding rod 5. The sliding rod 5 drives the two conductive arc petals 4 to slide to the energized position through the two connecting rods 51 and is locked by the locking member 6 set on the base 3. The sliding pin 71 is inserted into the flat ring of the connector 1 to lock the connector 1 and the base 3 in the component 11.

[0023] In this embodiment, the connector 1 has a flat ring. The side of the component 11 where it is connected has a mounting opening with a slot for the flat ring of the connector 1. The connector 1 is inserted after aligning the flat ring with the slot. The connector 1 abuts against the sliding rod 5 and pushes the sliding rod 5 towards the base 3. As the sliding rod 5 slides, it drives two conductive arc petals 4 to slide through the connecting rod 51. The two conductive arc petals 4 slide towards each other. The surfaces of the two sliding plates facing each other are arc-shaped, and the arc-shaped surfaces have slots for the flat ring of the connector 1. The two conductive arc petals 4 move closer to each other. During the process, the connector 1 is clamped, and the flat ring of the connector 1 is embedded in the clamping groove. The two conductive arc petals 4 can make contact with the flat ring surface of the connector 1 through their own clamping groove design, ensuring the stability of the energized connection. When the two conductive arc petals 4 enter the energized position, the locking member 6 is triggered and locks the sliding of the two conductive arc petals 4. The locking member 6 locks the sliding of the conductive arc petals 4, so that the conductive arc petals 4 and the connector 1 are connected in a fixed way. While the conductive arc petals 4 and the connector 1 are energized, the conductive arc petals 4 can also achieve the clamping and fixing effect of the connector 1, making the connection of the connector 1 in the mechanism more stable.

[0024] Locking element 6 includes two locking pins 61 that are slidably connected to the base 3 (see reference). Figure 3 Each of the two conductive arc petals 4 has a locking hole adapted to the locking pin 61. A first spring 62 is provided between the locking pin 61 and the base 3. One end of the first spring 62 is fixedly connected to the locking pin 61, and the other end is fixedly connected to the base 3. When the two conductive arc petals 4 are not in the energized position, the two locking pins 61 are not in the state of being directly opposite the locking hole. When the two slide plates are subjected to force and slide towards each other and reach the energized position, the two locking pins 61 are directly opposite the locking hole. At this time, the elastic potential energy of the first spring 62 is released, and the two first springs 62 push the two locking pins 61 to slide towards the locking hole and finally embed them into the locking hole. Since the axis of the locking pin 61 is perpendicular to the direction of movement of the conductive arc petals 4, after the locking pin 61 is embedded into the locking hole, the two conductive arc petals 4 can no longer slide along the installation direction, and thus the two conductive arc petals 4 complete the clamping of the docking head 1.

[0025] The sliding pin 71 is inserted into the hole of the connector 1 to lock the base 3. The diameter of the sliding pin 71 is adapted to the hole of the connector 1 (refer to...). Figure 6-8When the conductive arc flap 4 clamps the contact head 1 and the base 3 elastically resets, the sliding pin 71 is aligned with the hole of the contact head 1. A third spring 72 is also provided between the sliding pin 71 and the component 11. One end of the third spring 72 is fixedly connected to the sliding pin 71, and the other end is fixedly connected to the component 11. When the contact head 1 abuts against and pushes the slide rod 5 until the end of the contact head 1 near the base 3 abuts against the base 3, the sliding pin 71 moves upward under the elastic force of the third spring 72 and inserts into the round hole of the contact head 1. At this time, the contact head 1 is locked by the sliding pin 71 and can no longer slide along the insertion path. The contact head 1 slides in the direction of insertion, and at this time, the contact head 1 is engaged by the sliding pin 71 and clamped by the two conductive arc petals 4, and can no longer slide. It is worth mentioning that at this time, the contact head 1 can no longer move. Since the sliding pin 71 is engaged and the contact head 1 can no longer slide along the insertion direction, the sliding direction of the contact head 1 into the component 11 is the same as the sliding installation direction of the base 3 in the component 11. The contact head 1 reacts to the conductive arc petals 4 and the base 3. At this time, the base 3 can no longer slide along itself in the component 11. Therefore, at this time, the clamping of the contact head 1 by the mechanism is fixed and locked.

[0026] Auxiliary component 7 also includes a first locking plate 73 and a first locking block 74. The first locking plate 73 is fixed on the base 3, and the first locking block 74 is fixed on the sliding pin 71. When the connector 1 is not inserted, the side of the first locking plate 73 facing away from the base 3 abuts against the side of the first locking block 74 facing the base 3. A sliding post 31 is fixedly connected to component 11 (see reference). Figure 5 The base 3 is slidably connected to the component 11 via a sliding column 31. A second spring 32 is fitted on the sliding column 31. One end of the second spring 32 is fixedly connected to the sliding column 31, and the other end is fixedly connected to the base 3. After the connector 1 is inserted until the two conductive arc petals 4 enter the energized position, the installer slightly pulls the connector 1 away from the base 3. The connector 1 causes the conductive arc petals 4 and the base 3 to slide along the installation direction of the base 3. At this time, the second spring 32 is stretched and accumulates elastic potential energy. Since the base 3 is fixedly connected to the first clamping plate 73, the first clamping plate 73 is also stretched and slides together until the first clamping plate 73 no longer abuts against the first clamping block 74. The elastic potential energy of the third spring 72 is released, pushing the sliding pin 71 to slide closer to the connector 1. Since the operator pulls the connector 1 a certain distance away from the base 3, the sliding pin 71 is not directly connected to the hole of the connector 1. As a result, the sliding pin 71 moves upward until its end face close to the connector 1 abuts against the connector 1. Then the operator releases the connector 1, the elastic force of the second spring 32 is released and pulls the base 3 to slide closer to the second spring 32. The base 3 drives the conductive arc petal 4 and the connector 1 to slide together until the sliding pin 71 is directly connected to the hole of the connector 1. Under the pushing force of the third spring 72, the sliding pin 71 is inserted into the hole of the connector 1, completing the installation.

[0027] It is worth mentioning that the entire installation process only requires the operator to hold the connector 1 and push it into the component 11 until the conductive arc petal 4 completes the clamping of the connector 1. Then, the operator should slightly pull the connector 1 in the opposite direction and release the connector 1 to complete the installation. Compared with the prior art, the installation method of the connector 1 in this embodiment saves installation time and is simple and convenient. Finally, the connector 1 is locked in a fixed lock to avoid poor contact that is easy to occur with elastic clamping.

[0028] (refer to Figure 3-4 as well as Figure 8 An unlocking rod 8 is slidably connected to the side of component 11. The end of the unlocking rod 8 embedded in component 11 is rotatably connected to a transmission rod 81. The end of the transmission rod 81 away from the unlocking rod 8 is rotatably connected to a sliding pin 71. A locking pin 61 is slidably connected to a sliding column 31. A second locking block 611 is fixedly connected to the end of the locking pin 61 near the sliding column 31. A second locking plate 311 is fixedly connected to the end of the sliding column 31 near the locking pin 61. When the base 3 slides away from the sliding column 31, the second locking plate 311 and the second locking block 611 finally abut against each other and push the second locking block 611 and the locking pin 61 out of the lock hole. The elastic element on the sliding rod 5 includes a fourth spring.

[0029] In this embodiment, a specific method is provided for disassembling the connector 1. When disassembly is required, the operator pulls the unlocking lever 8. The unlocking lever 8 drives the sliding pin 71 to slide away from the connector 1 via the transmission rod 81 until the sliding pin 71 disengages from the hole of the connector 1. At this time, the sliding pin 71 no longer locks the connector 1. Then, the operator pulls the connector 1 outward. The connector 1 drives the conductive arc petal 4 and the base 3 to slide away from the component 11 together (the stroke of pulling the connector 1 this time is greater than the stroke of pulling the connector 1 during the installation process). Since the locking pin 61 is slidably connected to the base 3 and is subjected to the elastic force of the first spring 62, the locking pin 61 slides synchronously with the base 3. The base 3 slides along the axis of the sliding column 31 and stretches the second spring 32 (the second spring 3... (2. Energy storage) When the second locking plate 311 on the sliding column 31 is locked and abuts against the second locking block 611, the second locking plate 311 abuts against the lower locking pin 61 and no longer slides with the base 3. As the base 3 continues to move, the locking pin 61 slides relative to the base 3 until the locking pin 61 no longer locks against the locking hole. At this time, the contact head 1 continues to slide away from the component 11 under the force. Therefore, the sliding rod 5 is not subject to the clamping force of the contact head 1. The elastic force of the fourth spring pulls the sliding rod 5 to slide towards the contact head 1. The sliding rod 5 slides through the connecting rod 51 and drives the two conductive arc petals 4 to slide away from each other. Thus, during this process, the two conductive arc petals 4 release the clamping of the contact head 1, so the base 3 is no longer under the force. At this time, the contact head 1 continues to move away from the component 11 until disassembly is completed.

[0030] During this process, the unlocking lever 8 remains in a pulled state, and the operator does not release it, thus keeping the sliding pin 71 in a pulled state. There is a certain distance between the end face of the first locking block 74 fixedly connected to the sliding pin 71 facing the first locking plate 73 and the end face of the first locking plate 73 facing the first locking block 74. Subsequently, the base 3 is reset by the elastic force of the second spring 32 until the first locking plate 73 moves with the base 3 to directly above the first locking block 74. Then, the operator releases the unlocking lever 8, and the sliding pin 71 slides towards the base 3 by the elastic force of the third spring 72 until the first locking plate 73 abuts against the first locking block 74, completing the reset of the components inside the mechanism and facilitating the next installation.

[0031] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
