Description

Technical Field

[0001] The utility model relates to the field of wiring equipment, in particular to a wiring terminal. Background Art

[0002] When using the existing terminal block, it is necessary to bend the handle upward so that the other end of the handle pushes the fixed spring sheet inside the shell to compress and accumulate force to make an opening for the wire to be inserted, and then release the handle to reset the fixed spring sheet together with the hardware and clamp the wire; since the fixing spring sheet is a force accumulation process when the handle is bent upward (one end is fixed and the other end swings to accumulate force), it is more laborious to bend the handle upward. At the same time, the handle is partially pulled out when it is bent upward. Therefore, the force point for the fingers is small and the force is large, which can easily cause pain. Although the fingers are in a dead point state with the fixed spring sheet after being bent upward into place, the reverse elastic force of the fixed spring sheet after the dead point state is released will push the handle down to cause an impact, which can easily cause the handle to hit or clamp the fingers in some special cases.

Detailed implementation manners

[0042] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0043] Embodiment 1

[0044] Reference Figures 1 to 26 As Figures 1 to 6A terminal block shown in the figure includes a housing 10, the housing 10 is provided with a wiring port 11, and the housing 10 is further provided with a handle 20 hinged to the housing 10 so that it swings along the hinge point and forms a first position and a second position relative to the housing 10; a hardware part 30 for wiring and a fixing spring piece 40 linked with the handle 20 are arranged in the housing 10, and the fixing spring piece 40 presses a wire (not shown in the figure) on the hardware part 30. The fixing spring piece 40 includes a fixing section 41 and a swinging section 42 arranged at an angle to each other. The connection part between the fixing section 41 and the swinging section 42 is hinged to the housing 10; the handle 20 includes a fixing part 21 that abuts against one surface of the swinging section 42 when in the first position to push the fixing spring piece 40 to swing relative to the housing 10, so that the fixing section 41 abuts against the hardware part 30 and stores energy, and an unlocking part 22 that abuts against the other surface of the swinging section 42 when in the second position to push the fixing spring piece 40 to swing relative to the housing 10 in the reverse direction, so that the fixing section 41 moves away from the hardware part 30; the unlocking part 22 is hook-shaped. When the handle 20 is in the second position, the end of the swinging section 42 is located in the hook door 221 of the unlocking part 22, and the hook tip 222 of the unlocking part 22 winds from the end of the swinging section 42 to its lower side.

[0045] In the above structure, when the handle 20 swings, the fixing part 21 and the unlocking part 22 cooperate to drive the fixing section 41 to move away from or close to the hardware part 30 by driving the swinging section 42 of the fixing spring piece 40. The elastic force of the fixing section 41 acting on the hardware part 30 is generated by the elastic deformation between the fixing section 41 and the swinging section 42, and this elastic deformation is based on the pushing of the swinging section 42 when the handle 20 is in the first position. Therefore, when the handle 20 is in the first position, it can effectively provide energy storage guarantee for the fixing section 41; when the handle 20 reaches the second position, it will first release the energy storage of the fixing section 41, and use the hinge characteristic between the fixing spring piece 40 and the housing 10 to make the fixing section 41 move away from the hardware part 30. This action will not cause energy storage deformation of the fixing spring piece 40. Therefore, when the handle 20 reaches the second position, it can drive the fixing section 41 to swing in a resistance-free environment, making its operation easier and more convenient; the fixing part 21 abuts against the upper surface of the swinging section 42, and the unlocking part 22 is hook-shaped and winds from the end of the swinging section 42 to the lower surface position of the swinging section 42. When the handle 20 is transferred to the second position, the hook tip 222 of the unlocking part 22 is made to exert force at the lower surface position of the end of the swinging section 42 with a longer lever arm as much as possible. When the wire bites with the fixing section 41 (the wire bites with the end of the fixing section 41 when being pulled by an external force) or cold welding occurs, the separation force can be increased. At the same time, the hook-shaped unlocking part 22 can also effectively improve the overall strength, avoid the possibility of fracture, and is simple in structure and high in strength, and is also convenient for demolding during injection molding.

[0046] In this embodiment, a limiting recess 421 that is inclined downward and concave and then upward is provided at the end of the swinging section 42; during the process of the handle 20 switching from the second position to the first position, the fixing portion 21 abuts against the upper surface of the swinging section 42 and moves toward the end of the swinging section 42, and when the handle 20 reaches the first position, the fixing portion 21 slides into the limiting recess 421.

[0047] In the above structure, when the handle 20 gradually approaches the first position, the reverse elastic force of the fixing elastic piece 40 is greater. The provision of the limiting recess 421 can assist the fixing portion 21 to enter the area of the limiting recess 421 and reduce the reaction repulsive force when approaching the end of the first position.

[0048] In this embodiment, the hardware part 30 is located inside the wiring port 11 and at the lower side position of the wiring port 11; when the handle 20 is in the first position, it is in a pressed state and its swinging end faces the opening direction of the wiring port 11, and when the handle 20 is in the second position, it is in an upwardly turned state.

[0049] In the above structure, when the handle 20 is in the second position, it is in an upwardly turned state. Therefore, when the handle 20 is turned to the first position, a pressing operation is required. During this process, the fixing portion 21 will push the swinging section 42 so that the fixed section 41 abuts against the hardware part 30 and stores energy. However, since the entire finger can be pressed on the handle 20 during the pressing operation, the contact area between the finger and the handle 20 is greatly increased, reducing the discomfort of the finger and making its energy storage and force application more reasonable (in the prior art, the operation and force application direction of the handle are exactly opposite, so it is not conducive to operation).

[0050] In this embodiment, the housing 10 is provided with a handle groove 12 for accommodating the handle 20. When the handle 20 is in the first position, the two sides of the handle 20 and the side walls of the handle groove 12 are fixed by the cooperation of concave and convex points.

[0051] In the above structure, concave pits 23 are provided on both sides of the handle 20, and convex points 121 adapted to the concave pits 23 are provided on both sides of the handle groove 12. The two can provide positioning for the handle 20 to keep it in the first position; when the handle 20 is bent upward from the first position to the second position, this process is the process of releasing the stored energy of the fixing elastic piece 40. Since the swinging direction of the handle 20 is the same as the force application direction during the release process, the finger will not be hit by the handle 20 due to the ejection of the handle 20.

[0052] In this embodiment, the housing 10 includes a main body 13 and a side cover 14. A plurality of parallel holes 131 are provided on the side of the main body 13 facing away from the side cover 14, a plurality of insertion posts 132 are provided on the side of the main body 13 facing the side cover 14, and the side cover 14 is provided with insertion holes 141 that are inserted and matched with the insertion posts 132.

[0053] In the above structure, the main bodies 13 can be connected in parallel as needed, so that the plug-in column 132 of one main body 13 is plugged into the parallel hole 131 of another main body 13; or a secondary plug-in column 132 is provided on the side of the side cover 14 facing away from the main body 13 for plugging into the parallel hole 131 of another main body 13.

[0054] In this embodiment, when the handle 20 is in the first position, the distance L1 between the hinge point between the fixing spring piece 40 and the shell 10 and the wiring port 11 is smaller than the distance L2 between the hinge point between the handle 20 and the shell 10 and the wiring port 11; at the same time, the end of the fixing section 41 extends obliquely toward the depth of the wiring port 11 and abuts against the hardware 30.

[0055] In the above structure, when the wire (not shown in the figure) is inserted into the wiring port 11, it can smoothly pass between the fixing section 41 and the hardware 30 under the inclined guidance of the fixing section 41. At the same time, the inclined fixing section 41 can play a good anti-slip effect when pressing the wire onto the hardware 30.

[0056] In this embodiment, when the handle 20 is in the first position, a vertical line a between the fixing portion 21 and the hardware 30 is close to a vertical line b between the hinge between the fixing spring 40 and the housing 10 and the hardware 30 or the two vertical lines ab coincide with each other.

[0057] In the above structure, when the handle 20 reaches the first position, the fixing portion 21 is as close to the dead point as possible to reduce the reverse force of the fixing spring 40 on the handle 20 after the fixed spring 40 accumulates force, so that the handle 20 can be fixed in the first position with less resistance when the concave and convex points cooperate.

[0058] In this embodiment, a pin 31 connected to the hardware 30 is provided at the bottom of the housing 10 .

[0059] In the above structure, the pins 31 are exposed for soldering on a circuit board or wiring.

[0060] Example 2

[0061] refer to Figures 1 to 26 ,like Figures 7 to 12A wiring terminal shown in the figure comprises a housing 10, wherein the housing 10 is provided with a wiring port 11, and the housing 10 is further provided with a handle 20 which is hinged to the housing 10 so as to swing along the hinge point and form a first position and a second position relative to the housing 10; the housing 10 is provided with a hardware 30 for wiring and a fixed spring 40 which is linked with the handle 20 and presses the wire (not shown in the figure) onto the hardware 30, wherein the fixed spring 40 comprises a fixed section 41 and a swing section 42 which are arranged at an angle to each other, and the connection between the fixed section 41 and the swing section 42 is hinged to the housing 10; the handle 20 includes a fixing portion 21 which, when in the first position, abuts against one side of the swinging section 42 to push the fixing spring sheet 40 to swing relative to the shell 10 so that the fixing section 41 abuts against the hardware 30 and accumulates force, and an unlocking portion 22 which, when in the second position, abuts against the other side of the swinging section 42 to push the fixing spring sheet 40 to swing relative to the shell 10 so that the fixing section 41 is away from the hardware 30; the unlocking portion 22 is hook-shaped, and when the handle 20 is in the second position, the end of the swinging section 42 is located in the hook gate 221 of the unlocking portion 22, and the hook tip 222 of the unlocking portion 22 is wrapped from the end of the swinging section 42 to the bottom thereof.

[0062] In the above structure, when the handle 20 swings, the fixing portion 21 cooperates with the unlocking portion 22 to drive the fixing segment 41 away from or close to the hardware 30 by driving the swinging segment 42 of the fixing spring sheet 40. The elastic force of the fixing segment 41 on the hardware 30 is generated by the elastic deformation between the fixing segment 41 and the swinging segment 42, and the elastic deformation is based on the pushing of the swinging segment 42 by the handle 20 when it is in the first position. Therefore, the handle 20 can effectively provide force storage guarantee for the fixing segment 41 when it is in the first position; and when the handle 20 reaches the second position, the force storage of the fixing segment 41 will be released first, and the hinged characteristic between the fixing spring sheet 40 and the shell 10 will be used to make the fixing segment 41 away from the hardware 30. This action will not cause force storage deformation to the fixing spring sheet 40. shape, so when the handle 20 reaches the second position, it can drive the fixed section 41 to swing in an environment without resistance, making its operation easier and more convenient; the fixed portion 21 is against the upper surface of the swing section 42, and the unlocking portion 22 is hooked from the end of the swing section 42 to the lower surface of the swing section 42. When the handle 20 is transferred to the second position, the hook tip 222 of the unlocking portion 22 is first applied to the lower surface of the end of the swing section 42 with a longer force arm. When the wire and the fixed section 41 are bitten (the wire is bitten to the end of the fixed section 41 when pulled by external force) or cold welded, the separation force can be increased. At the same time, the hook-shaped unlocking portion 22 can also effectively improve the overall strength and avoid the possibility of breakage. The structure is simple and strong, and it is also convenient for demolding during injection molding.

[0063] In this embodiment, a limiting recess 421 that is inclined downward and concave and then upward is provided at the end of the swinging section 42 in the direction of its end; during the process of the handle 20 switching from the second position to the first position, the fixing portion 21 abuts against the upper surface of the swinging section 42 and moves in the direction of the end of the swinging section 42, and when the handle 20 reaches the first position, the fixing portion 21 slides into the limiting recess 421.

[0064] In the above structure, when the handle 20 gradually approaches the first position, the reverse elastic force of the fixing elastic piece 40 is greater. The setting of the limiting recess 421 can assist the fixing portion 21 to enter the area of the limiting recess 421 and reduce the reaction repulsive force when approaching the end of the first position.

[0065] In this embodiment, the hardware part 30 is located inside the wiring port 11 and at the lower side position of the wiring port 11; when the handle 20 is in the first position, it is in a pressed state and its swinging end faces the opening direction of the wiring port 11, and when the handle 20 is in the second position, it is in an upturned state.

[0066] In the above structure, when the handle 20 is in the second position, it is in an upturned state. Therefore, when the handle 20 is turned to the first position, a pressing operation is required. During this process, the fixing portion 21 will push the swinging section 42 so that the fixing section 41 abuts against the hardware part 30 and stores energy. However, since the whole finger can be pressed on the handle 20 during the pressing operation, the contact area between the finger and the handle 20 is greatly increased, the discomfort of the finger is reduced, and its energy storage and force application are more reasonable (in the prior art, the operation and force application direction of the handle are just the opposite, so it is not conducive to operation).

[0067] In this embodiment, the housing 10 is provided with a handle groove 12 for accommodating the handle 20. When the handle 20 is in the first position, the two sides of the handle 20 and the side walls of the handle groove 12 are fixed by the cooperation of concave and convex points.

[0068] In the above structure, concave pits 23 are provided on both sides of the handle 20, and convex points 121 adapted to the concave pits 23 are provided on both sides of the handle groove 12. The two can provide positioning for the handle 20 to keep it in the first position; when the handle 20 is bent upward from the first position to the second position, this process is the process of the fixing elastic piece 40 storing and releasing energy. Since the swinging direction of the handle 20 is the same as the force application direction during the release process, the finger will not be hit by the handle 20 due to the ejection of the handle 20.

[0069] In this embodiment, the housing 10 includes a main body 13 and a side cover 14. A plurality of parallel holes 131 are provided on the side of the main body 13 facing away from the side cover 14, a plurality of insertion posts 132 are provided on the side of the main body 13 facing the side cover 14, and the side cover 14 is provided with insertion holes 141 that are inserted and matched with the insertion posts 132.

[0070] In the above structure, the main bodies 13 can be connected in parallel as needed, so that the plug-in column 132 of one main body 13 is plugged into the parallel hole 131 of another main body 13; or a secondary plug-in column 132 is provided on the side of the side cover 14 facing away from the main body 13 for plugging into the parallel hole 131 of another main body 13.

[0071] In this embodiment, when the handle 20 is in the first position, the distance L1 between the hinge point between the fixing spring piece 40 and the shell 10 and the wiring port 11 is smaller than the distance L2 between the hinge point between the handle 20 and the shell 10 and the wiring port 11; at the same time, the end of the fixing section 41 extends obliquely toward the depth of the wiring port 11 and abuts against the hardware 30.

[0072] In the above structure, when the wire (not shown in the figure) is inserted into the wiring port 11, it can smoothly pass between the fixing section 41 and the hardware 30 under the inclined guidance of the fixing section 41. At the same time, the inclined fixing section 41 can play a good anti-slip effect when pressing the wire onto the hardware 30.

[0073] In this embodiment, when the handle 20 is in the first position, a vertical line a between the fixing portion 21 and the hardware 30 is close to a vertical line b between the hinge between the fixing spring 40 and the housing 10 and the hardware 30 or the two vertical lines ab coincide with each other.

[0074] In the above structure, when the handle 20 reaches the first position, the fixing portion 21 is as close to the dead point as possible to reduce the reverse force of the fixing spring 40 on the handle 20 after the fixed spring 40 accumulates force, so that the handle 20 can be fixed in the first position with less resistance when the concave and convex points cooperate.

[0075] In this embodiment, a pin 31 connected to the hardware 30 is disposed on the back of the housing 10 .

[0076] In the above structure, the pins 31 are exposed for soldering on a circuit board or wiring.

[0077] Example 3

[0078] refer to Figures 1 to 26 ,like Figures 13 to 21A terminal block shown in the figure includes a housing 10, the housing 10 is provided with a wiring port 11, and the housing 10 is further provided with a handle 20 hinged to the housing 10 so that it swings along the hinge point and forms a first position and a second position relative to the housing 10; a hardware part 30 for wiring and a fixing spring piece 40 linked with the handle 20 are arranged in the housing 10, and the fixing spring piece 40 presses a wire (not shown in the figure) on the hardware part 30. The fixing spring piece 40 includes a fixing section 41 and a swinging section 42 arranged at an angle to each other, and the connection part of the fixing section 41 and the swinging section 42 is hinged to the housing 10; the handle 20 includes a fixing part 21 that abuts against one surface of the swinging section 42 when in the first position to push the fixing spring piece 40 to swing relative to the housing 10, so that the fixing section 41 abuts against the hardware part 30 and stores energy, and an unlocking part 22 that abuts against the other surface of the swinging section 42 when in the second position to push the fixing spring piece 40 to swing relative to the housing 10 in the reverse direction, so that the fixing section 41 moves away from the hardware part 30; the unlocking part 22 is hook-shaped, when the handle 20 is in the second position, the end of the swinging section 42 is located in the hook door 221 of the unlocking part 22, and the hook tip 222 of the unlocking part 22 winds from the end of the swinging section 42 to its lower side.

[0079] In the above structure, when the handle 20 swings, the fixing part 21 and the unlocking part 22 cooperate to drive the fixing section 41 to move away from or close to the hardware part 30 by driving the swinging section 42 of the fixing spring piece 40. The elastic force of the fixing section 41 acting on the hardware part 30 is generated by the elastic deformation between the fixing section 41 and the swinging section 42, and this elastic deformation is based on the pushing of the swinging section 42 when the handle 20 is in the first position. Therefore, when the handle 20 is in the first position, it can effectively provide energy storage guarantee for the fixing section 41; when the handle 20 reaches the second position, it will first release the energy storage of the fixing section 41, and use the hinge characteristic between the fixing spring piece 40 and the housing 10 to make the fixing section 41 move away from the hardware part 30. This action will not cause energy storage deformation of the fixing spring piece 40. Therefore, when the handle 20 reaches the second position, it can drive the fixing section 41 to swing in a resistance-free environment, making its operation easier and more convenient; the fixing part 21 abuts against the upper surface of the swinging section 42, and the unlocking part 22 is hook-shaped and winds from the end of the swinging section 42 to the lower surface position of the swinging section 42. When the handle 20 is transferred to the second position, the hook tip 222 of the unlocking part 22 is made to act on the lower surface position of the end of the swinging section 42 with a longer lever arm as much as possible. When the wire bites with the fixing section 41 (the wire bites with the end of the fixing section 41 when being pulled by an external force) or cold welding occurs, the separation force can be increased. At the same time, the hook-shaped unlocking part 22 can also effectively improve the overall strength and avoid the possibility of fracture. The structure is simple and has high strength, and it is also convenient for demoulding during injection molding.

[0080] In this embodiment, a limiting recess 421 that is inclined downward and concave and then upward is provided at the end of the swinging section 42; during the process of the handle 20 switching from the second position to the first position, the fixing portion 21 abuts against the upper surface of the swinging section 42 and moves toward the end of the swinging section 42, and when the handle 20 reaches the first position, the fixing portion 21 slides into the limiting recess 421.

[0081] In the above structure, when the handle 20 gradually approaches the first position, the reverse elastic force of the fixing elastic piece 40 is greater. The provision of the limiting recess 421 can assist the fixing portion 21 to enter the area of the limiting recess 421 and reduce the reaction repulsive force when approaching the end of the first position.

[0082] In this embodiment, the hardware part 30 is located inside the wiring port 11 and at the lower side position of the wiring port 11; when the handle 20 is in the first position, it is in a pressed state and its swinging end faces the opening direction of the wiring port 11, and when the handle 20 is in the second position, it is in an upwardly turned state.

[0083] In the above structure, when the handle 20 is in the second position, it is in an upwardly turned state. Therefore, when the handle 20 is turned to the first position, a pressing operation is required. During this process, the fixing portion 21 will push the swinging section 42 so that the fixed section 41 abuts against the hardware part 30 and stores energy. However, since the entire finger can be pressed on the handle 20 during the pressing operation, the contact area between the finger and the handle 20 is greatly increased, the discomfort of the finger is reduced, and its energy storage and force application are more reasonable (in the prior art, the operation and force application direction of the handle are exactly opposite, so it is not conducive to operation).

[0084] In this embodiment, the housing 10 is provided with a handle groove 12 for accommodating the handle 20. When the handle 20 is in the first position, the two sides of the handle 20 and the side walls of the handle groove 12 are fixed by the cooperation of concave and convex points.

[0085] In the above structure, concave pits 23 are provided on both sides of the handle 20, and convex points 121 adapted to the concave pits 23 are provided on both sides of the handle groove 12. The two can provide positioning for the handle 20 to keep it in the first position; when the handle 20 is bent upward from the first position to the second position, this process is the process of energy storage release of the fixing elastic piece 40. Since the swinging direction of the handle 20 is the same as the force application direction during the release process, the finger will not be hit by the handle 20 due to the pop-up of the handle 20.

[0086] In this embodiment, the housing 10 includes a main body 13 and a side cover 14. A plurality of parallel holes 131 are provided on the side of the main body 13 facing away from the side cover 14, a plurality of insertion posts 132 are provided on the side of the main body 13 facing the side cover 14, and the side cover 14 is provided with insertion holes 141 that are inserted and matched with the insertion posts 132.

[0087] In the above structure, the main bodies 13 can be connected in parallel as needed, so that the insertion post 132 of one main body 13 is inserted into the parallel connection hole 131 of another main body 13; or a secondary insertion post 132 is provided on the side of the side cover 14 facing away from the main body 13 for insertion into the parallel connection hole 131 of another main body 13.

[0088] In this embodiment, when the handle 20 is in the first position, the distance L1 between the hinge point between the fixed elastic piece 40 and the housing 10 and the wiring port 11 is less than the distance L2 between the hinge point between the handle 20 and the housing 10 and the wiring port 11; at the same time, the end of the fixed section 41 extends obliquely towards the deep direction of the wiring port 11 and abuts against the hardware part 30.

[0089] In the above structure, when the wire (not shown in the figure) is inserted into the wiring port 11, it can smoothly pass between the fixed section 41 and the hardware part 30 under the inclined guidance of the fixed section 41. At the same time, the inclined fixed section 41 can play a good anti-disconnection effect when pressing the wire on the hardware part 30.

[0090] In this embodiment, when the handle 20 is in the first position, the perpendicular line a between the fixed part 21 and the hardware part 30 is close to the perpendicular line b between the hinge point of the fixed elastic piece 40 and the housing 10 and the hardware part 30, or the two perpendicular lines a and b coincide with each other.

[0091] In the above structure, when the handle 20 reaches the first position, the fixed part 21 is as close as possible to the dead point position to reduce the reverse force of the fixed elastic piece 40 on the handle 20 after storing energy, so that the handle 20 can be fixed in the first position with less resistance when the concave and convex points are matched.

[0092] In this embodiment, the back of the housing 10 is provided with a mating part 15, and one end of the hardware part 30 away from the wiring port 11 is located in the mating part 15; the mating part 15 is used to be inserted into the mating part 15 of another housing 10; when the mating parts 15 of the two housings 10 are inserted into each other, the hardware parts 30 of each housing 10 are in contact and connected with each other.

[0093] In the above structure, it can be used to connect two wires; the end of the hardware part 30 located in the wiring port 11 is inclined to form a guiding surface 32, and the hardware part 30 of another housing 10 is turned over so that the two hardware parts 30 can be guided and inserted into each other through the guiding surface 32 when the mating parts 15 of the two housings 10 are mated.

[0094] Embodiment 4

[0095] Reference Figures 1 to 26 As Figures 22 to 26A terminal block as shown includes a housing 10, the housing 10 is provided with a wiring port 11, and the housing 10 is further provided with a handle 20 hinged to the housing 10 so that it swings along the hinge point and forms a first position and a second position relative to the housing 10; a hardware part 30 for wiring and a fixing spring piece 40 linked with the handle 20 are arranged in the housing 10, and the fixing spring piece 40 presses a wire (not shown in the figure) on the hardware part 30. The fixing spring piece 40 includes a fixing section 41 and a swinging section 42 arranged at an angle to each other. The connection part between the fixing section 41 and the swinging section 42 is hinged to the housing 10; the handle 20 includes a fixing part 21 that abuts against one surface of the swinging section 42 in the first position to push the fixing spring piece 40 to swing relative to the housing 10, so that the fixing section 41 abuts against the hardware part 30 and stores energy, and an unlocking part 22 that abuts against the other surface of the swinging section 42 in the second position to push the fixing spring piece 40 to swing relative to the housing 10 in the reverse direction, so that the fixing section 41 moves away from the hardware part 30; the unlocking part 22 is hook-shaped. When the handle 20 is in the second position, the end of the swinging section 42 is located in the hook door 221 of the unlocking part 22, and the hook tip 222 of the unlocking part 22 winds around from the end of the swinging section 42 to its lower side.

[0096] In the above structure, when the handle 20 swings, the fixing part 21 and the unlocking part 22 cooperate to drive the fixing section 41 to move away from or close to the hardware part 30 by driving the swinging section 42 of the fixing spring piece 40. The elastic force of the fixing section 41 acting on the hardware part 30 is generated by the elastic deformation between the fixing section 41 and the swinging section 42, and this elastic deformation is based on the pushing of the swinging section 42 when the handle 20 is in the first position. Therefore, when the handle 20 is in the first position, it can effectively provide energy storage guarantee for the fixing section 41; when the handle 20 reaches the second position, it will first release the energy storage of the fixing section 41, and use the hinge characteristic between the fixing spring piece 40 and the housing 10 to make the fixing section 41 move away from the hardware part 30. This action will not cause energy storage deformation of the fixing spring piece 40. Therefore, when the handle 20 reaches the second position, it can drive the fixing section 41 to swing in a resistance-free environment, making its operation easier and more convenient; the fixing part 21 abuts against the upper surface of the swinging section 42, and the unlocking part 22 is hook-shaped and winds around from the end of the swinging section 42 to the lower surface position of the swinging section 42. When the handle 20 is transferred to the second position, the hook tip 222 of the unlocking part 22 is made to exert force on the lower surface position of the end of the swinging section 42 with a longer lever arm as much as possible. When the wire bites with the fixing section 41 (the wire bites with the end of the fixing section 41 when being pulled by an external force) or cold welding occurs, the separation force can be increased. At the same time, the hook-shaped unlocking part 22 can also effectively improve the overall strength, avoid the possibility of fracture, and is simple in structure and high in strength, and is also convenient for demolding during injection molding.

[0097] In this embodiment, a limiting recess 421 that is inclined downward and concave and then upward is provided at the end of the swinging section 42; during the process of the handle 20 switching from the second position to the first position, the fixing portion 21 abuts against the upper surface of the swinging section 42 and moves toward the end of the swinging section 42, and when the handle 20 reaches the first position, the fixing portion 21 slides into the limiting recess 421.

[0098] In the above structure, when the handle 20 gradually approaches the first position, the reverse elastic force of the fixing elastic piece 40 is greater. The provision of the limiting recess 421 can assist the fixing portion 21 to enter the area of the limiting recess 421 and reduce the reaction repulsive force when approaching the end of the first position.

[0099] In this embodiment, the hardware part 30 is located in the wiring port 11 and at the lower side position of the wiring port 11; when the handle 20 is in the first position, it is in a pressed state and its swinging end faces the opening direction of the wiring port 11, and when the handle 20 is in the second position, it is in an upward-flipped state.

[0100] In the above structure, when the handle 20 is in the second position, it is in an upward-flipped state. Therefore, when the handle 20 is switched to the first position, a pressing operation is required. During this process, the fixing portion 21 will push the swinging section 42 so that the fixed section 41 abuts against the hardware part 30 and stores energy. However, since the entire finger can be pressed on the handle 20 during the pressing operation, the contact area between the finger and the handle 20 is greatly increased, reducing the discomfort of the finger and making its energy storage and force application more reasonable (in the prior art, the operation and force application direction of the handle are exactly opposite, so it is not conducive to operation).

[0101] In this embodiment, the housing 10 is provided with a handle groove 12 for accommodating the handle 20. When the handle 20 is in the first position, the two sides of the handle 20 and the side walls of the handle groove 12 are fixed by the cooperation of concave and convex points.

[0102] In the above structure, concave pits 23 are provided on both sides of the handle 20, and convex points 121 adapted to the concave pits 23 are provided on both sides of the handle groove 12. The two can provide positioning for the handle 20 and keep it in the first position; when the handle 20 is bent upward from the first position to the second position, this process is a process of releasing the stored energy of the fixing elastic piece 40. Since the swinging direction of the handle 20 is the same as the force application direction during the release process, the finger will not be hit by the handle 20 due to the ejection of the handle 20.

[0103] In this embodiment, the housing 10 includes a main body 13 and a side cover 14.

[0104] In this embodiment, when the handle 20 is in the first position, the distance L1 between the hinge point between the fixed elastic piece 40 and the housing 10 and the wiring port 11 is less than the distance L2 between the hinge point between the handle 20 and the housing 10 and the wiring port 11; at the same time, the end of the fixed section 41 extends obliquely towards the depth of the wiring port 11 and abuts against the hardware part 30.

[0105] In the above structure, when a wire (not shown in the figure) is inserted into the wiring port 11, it can smoothly pass between the fixed section 41 and the hardware part 30 under the inclined guidance of the fixed section 41. At the same time, the inclined fixed section 41 can play a good anti - detachment effect when pressing the wire against the hardware part 30.

[0106] In this embodiment, when the handle 20 is in the first position, the perpendicular line a between the fixed part 21 and the hardware part 30 is close to the perpendicular line b between the hinge point of the fixed elastic piece 40 and the housing 10 and the hardware part 30, or the two perpendicular lines a and b coincide with each other.

[0107] In the above structure, when the handle 20 reaches the first position, the fixed part 21 is as close as possible to the dead - point position to reduce the reverse force of the fixed elastic piece 40 on the handle 20 after energy storage, so that when the concave - convex points are matched, the handle 20 can be fixed in the first position with a smaller resistance.

[0108] In this embodiment, there are two housings 10 which are symmetrically arranged and integrally connected; the hardware part 30 passes through the two housings 10 and is adapted to the fixed elastic pieces 40 of each housing 10.

[0109] In the above structure, the two housings 10 are integrally injection - molded to form a whole.

[0110] In this embodiment, guide - rail buckles 16 are provided at the bottoms of the two housings 10.

[0111] In the above structure, the guide - rail buckles 16 are used to be adapted to the guide rails in the distribution box.

[0112] Advantages of the present utility model: When the handle 20 swings, the fixing part 21 cooperates with the unlocking part 22 to drive the fixed section 41 to move away from or close to the hardware 30 by driving the swinging section 42 of the fixed elastic piece 40. The elastic force exerted by the fixed section 41 on the hardware 30 is generated by the elastic deformation between the fixed section 41 and the swinging section 42, and this elastic deformation is based on the pushing of the swinging section 42 when the handle 20 is in the first position. Therefore, when the handle 20 is in the first position, it can effectively provide energy storage guarantee for the fixed section 41; when the handle 20 reaches the second position, it will first release the energy storage of the fixed section 41 and use the hinged characteristic between the fixed elastic piece 40 and the housing 10 to make the fixed section 41 move away from the hardware 30. This action will not cause energy storage deformation of the fixed elastic piece 40. Therefore, when the handle 20 reaches the second position, it can drive the fixed section 41 to swing in a resistance-free environment, making its operation easier and more convenient; the fixing part 21 abuts against the upper surface of the swinging section 42, and the unlocking part 22 is in a hook shape and winds from the end of the swinging section 42 to the lower surface position of the swinging section 42. When the handle 20 is transferred to the second position, the hook tip 222 of the unlocking part 22 is made to act on the lower surface position of the end of the swinging section 42 with a longer lever arm as much as possible. When the wire is engaged with the fixed section 41 (the wire bites with the end of the fixed section 41 when being pulled by an external force) or cold-welded, the separation force can be increased. At the same time, the hook-shaped unlocking part 22 can also effectively improve the overall strength and avoid the possibility of fracture. While the structure is simple and has high strength, it is also convenient for demolding during injection molding.

[0113] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and modifications can be made. These improvements and modifications made under the above assumptions should also be regarded as the protection scope of the present utility model.
