Description

Technical Field

[0001] The invention relates to a structural combination of mutually insulated electrical connection elements, in particular to a circuit connector. Background Art

[0002] Circuit connectors are devices that are frequently used in power construction, circuit conduction and other occasions. Especially in high-voltage and high-current lines, power connectors play an important role. From the perspective of line safety, they mainly use electrical equipment such as circuit breakers to protect the circuit, that is, when a circuit fails, the circuit is quickly cut off. However, in special circumstances, such as a fire, the lines still remain physically connected, and the male connector is always located in the female connector, so there is still a risk of fire spreading. It should also be noted that the existing circuit connectors are mainly designed from the perspective of circuit conduction, and are relatively lacking in safety protection. Increasing the safety performance of circuit connectors is also of great research significance for safe use of electricity. Summary of the invention

[0003] In order to solve the deficiencies in the prior art, the purpose of the present invention is to provide a line connector that can quickly cut off the circuit. When a circuit fails, the limiting element will switch to a released state, and the power provided by the driving element will be used to push the embedded block and the male connector to move outward, and the male connector and the female connector will be separated. In addition, the invention also adopts an anti-misinsertion function. Only when two pins are inserted at the same time can the embedded block be pushed to move. The pins push the inner slider and the energizing element, so that the energizing element releases the restriction on the embedded block, thereby realizing the connection between the male connector and the female connector.

[0004] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows.

[0005] A power line connector comprises a male connector and a female connector. The female connector comprises a support body. Two embedded blocks are slidably arranged in the support body and are matched with the pins on the male connector. A driving element and a moving element are installed in the support body. The embedded blocks can switch between an extended state and a buried state and the initial state is the extended state. The embedded blocks receive the force of the pins and can switch from the extended state to the buried state; the moving element can switch between a floating state and a sunken state. The force applied by the embedded blocks to the moving element is used to push the moving element to switch from the floating state to the sunken state; the driving element can switch between a jacking state and an energy storage state. A bearing frame body is slidably arranged in the support body. The bearing frame body is connected to the driving element. The embedded blocks apply a force to the bearing frame body and push the driving element to switch from the jacking state to the energy storage state.

[0006] Based on the technical solution adopted in the present invention, when the male connector is inserted, the pin on the male connector will push the embedded block to move inward, and the kinetic energy generated during the movement of the embedded block is converted into potential energy accumulated in the driving element. At the same time, the embedded block also pushes the moving element to move inward. The movement of the embedded block and the moving element provides a spatial range for the insertion of the pin. In the present invention, the limiting element can maintain the position of the supporting frame and can also maintain the driving element in an energy storage state. When a line fault occurs, the limiting element will cancel the restriction on the driving element, and the driving element will release the elastic potential energy, which will push the supporting frame and the embedded block to move outward, and realize the rapid separation of the male connector and the female connector.

[0007] A further improvement and optimization of the above technical solution is that a limiting element is also installed in the support body, and the limiting element can be freely switched between a constrained state and a released state. The limiting element is used to stabilize the position of the support frame and keep the driving element in an energy storage state. Its function is to impose a limit on the support frame and to impose a limit on the driving element. When the limiting element receives an external line fault signal, it will switch from a constrained state to a released state. The limiting element in the released state will cancel the restriction on the support frame, and the driving element in the energy storage state will switch to a lifting state, and push the support frame and the embedded block to move upward.

[0008] Preferably, the support body is fixedly provided with a fixed frame, two limiting elements are provided and are respectively provided at one end of the fixed frame, the limiting element comprises a limiting base slidably connected to the fixed frame, a connecting rod is fixedly connected to the limiting base, a limiting spring is provided between the fixed frame and the limiting base, and the elastic force provided by the limiting spring is used to pull the connecting rod to conflict with the fixed frame; A driving rod fixed on the fixed frame is also provided between the two limiting elements, and pistons are slidably matched at both ends of the driving rod, and the limiting base is connected to the pistons on the corresponding end sides through the piston rod; a resistor is provided in the driving rod; its function is that when a short circuit or other fault occurs in the line, the resistor is energized and can generate a large amount of heat energy in the driving cylinder, and the pistons at both ends of the driving cylinder extend outward, and the kinetic energy of the pistons is transmitted to the limiting base and the connecting rod through the piston rod, and the movement of the connecting rod deviates from the fixed frame to provide spatial avoidance for releasing the supporting frame.

[0009] For further improvement, the support frame is provided with an inclined pushing base surface, and the suspended end of the connecting rod is fixedly provided with a matching base surface matching the pushing base surface; its function is that when the support frame moves toward the fixed frame, the support frame will push the connecting rod to move outward and provide space for the support frame to continue to move downward, and when the support frame moves to the lower end of the matching base surface, the limiting element will also be reset to the constrained state.

[0010] Further improvement and optimization of the above technical solution, a fixed frame is fixedly installed in the support body, a moving element is slidably arranged on the fixed frame, an intermediate guide rod parallel to the insertion direction of the male connector is arranged on the moving element, the embedded block is slidably matched with the intermediate guide rod, the intermediate guide rod is sleeved with an intermediate spring, and the elastic force of the intermediate spring pushes the embedded block and the moving element to separate; its function is that the moving element slidably arranged on the fixed frame can accept the kinetic energy of the embedded block, and when the embedded block continues to move inward, the embedded block will push the intermediate spring to elastically contract, the interval between the embedded block and the moving element is narrowed, and space avoidance is provided for the insertion of the pin.

[0011] What also needs to be improved is that a driving element is fixedly arranged on the fixed frame body, the driving element includes a cylindrical center guide column, a driving spring is arranged in the center guide column, a bearing frame body in the shape of an "I" is slidably matched inside the center guide column, a connecting column arranged along the insertion direction of the pin is connected to the bearing frame body, a driving plug that is slidably matched with the center guide column is installed at the end of the connecting column, one end of the driving spring is against the bottom of the center guide column, and the other end is against the driving plug, and the elastic force of the driving spring is used to push the bearing frame body away from the bottom of the center guide column; its function is that the kinetic energy of the inward movement of the embedded block is transmitted to the bearing frame body, and the bearing frame body prompts the driving spring to find elastic contraction, and the elastic potential energy accumulated by the driving spring will become the power to push the pin out of the female connector. In addition, the bearing frame body is arranged in the shape of an "I", which can make the center guide column evenly stressed in the female connector and better bear the thrust transmitted by the embedded block. Moreover, the bearing frame body can also play a role in limiting the detachment of the embedded block.

[0012] For further improvement and optimization, a connecting air hole is provided at the bottom of the center guide column, and the connecting air hole is connected with the inner cavity of the driving rod; a resistance element is also provided in the center guide column, and the resistance element includes an inner sleeve connected with the connecting air hole and sleeved on the outside of the connecting air hole; an air blocking plug which can slide along its axial direction is movably provided in the inner sleeve; an outer sleeve is sleeved on the outer surface of the inner sleeve; a sealing cover is provided at the upper end of the outer sleeve and an air guide hole is provided at the center of the sealing cover; an air guide column matching the air guide hole is provided at the upper end of the air blocking plug, and an air guide ring groove is provided on the air guide column; a spacing channel a is provided between the upper end of the inner sleeve and the sealing cover, a spacing channel b is provided between the outer sleeve and the inner sleeve, an air vent connected with the spacing channel b is provided at the bottom of the center guide column, and the end of the air vent is connected to the external atmosphere.

[0013] In the present invention, the resistance element arranged in the center guide column greatly improves the safety performance. When a line fault occurs, the continuous operation of the resistor causes the internal temperature to rise rapidly, and the resistance element is switched to the isolation state. The center guide column cannot be connected to the external atmosphere through the resistance element to form a closed cavity, thereby preventing the embedded block from moving inward, completely blocking the connection between the male connector pin and the energized element in the female connector.

[0014] A further improvement is that an upper protrusion is provided on the embedded block, and when the embedded block moves inward, the upper protrusion is in contact with the support frame body, and the embedded block drives the support frame body to move toward the fixed frame body; the connection between the embedded block and the intermediate guide rod is a resistance part, which is always located at the lower end of the support frame body, and when the embedded block extends its stroke outward, the resistance part resists the bottom of the support frame body; its function is that by setting the upper protrusion, when the embedded block moves inward, the upper protrusion can contact the support frame body to realize the transfer of kinetic energy of the embedded block to the support frame body, and through the restrictive function of the support frame body on the resistance part, the embedded block can be prevented from detaching from the support body under the elastic action of the intermediate spring.

[0015] What needs to be specified and optimized is that a connecting frame is fixedly provided at the bottom of the moving element, and a bottom spring is provided between the supporting body and the connecting frame. The elastic force provided by the bottom spring is used to push the connecting frame and the moving element to move in the outward extension direction; its function is that the embedded block pushes the moving element to continue to move toward the bottom of the supporting body, the bottom spring is connected to the moving element through the connecting frame and realizes elastic support for it, and the movement of the embedded block and the moving element in the supporting body provides insertion space for the pin of the male connector. When the limiting element switches to the initial state (release state), the bottom spring will also release the elastic potential energy and push the moving element to reset.

[0016] Further improvement and optimization of the above technical solution, an inner slider is slidably matched in the embedded block, a lifting spring is arranged between the bottom of the embedded block and the inner slider, an interface groove matching the energizing element and used for inserting the energizing element is arranged on the embedded block, the energizing element is a rectangular block and is slidably arranged in the support body, the movement direction of the energizing element is perpendicular to the movement direction of the embedded block, a fastening spring is arranged between the energizing element and the support body, and the elastic force provided by the fastening spring is used to push the energizing element toward the embedded block; its function is that when the pin of the male connector is inserted into the embedded block, the pin will push the inner slider to move in the embedded block and cause the lifting spring to elastically contract, and the continuous downward movement of the inner slider will push the energizing element to disengage from the embedded block, so as to release the restrictive effect of the energizing element on the embedded block. By utilizing this function, it is possible to effectively prevent mis-insertion, and the pin can also be set to a non-standard structure, thereby effectively preventing situations such as misconnection of the line.

[0017] What needs to be improved is that an inclined transition slope is provided at one end of the power-carrying element facing the embedded block, and a guiding slope matching the transition slope is provided at the bottom of the inner slider; its function is that the power-carrying element is inserted into the embedded block, thereby restricting the movement of the embedded block along the insertion direction of the pin, and when the inner slider applies a thrust to the power-carrying element, the embedded block can be separated from the power-carrying element to achieve the smooth introduction of the male connector pin.

[0028] like Figure 1As shown, the power line connector includes a male connector (not shown in the figure) and a female connector. A safety protection structure is arranged in the female connector. When a short circuit or a line fault occurs, the safety protection structure can directly pop out the male connector, and while disconnecting the line connection, the two lines can be kept away from each other, which can prevent the line fire caused by the circuit fault from spreading to other electric wires. In addition, in the present invention, an anti-misinsertion structure is arranged on the female connector, and the safety performance of the circuit will be further improved by utilizing this structure.

[0029] More specifically, see Appendix Figure 2 , 4 As shown, the female connector includes a support body, in which two embedded blocks 10 are slidably arranged, the number of the embedded blocks 10 is adapted to the number of pins on the male connector and corresponds to the live wire and the neutral wire respectively, specifically, a fixed frame 51 is fixedly installed in the support body, a moving element 50 is slidably arranged on the fixed frame 51, an intermediate guide rod parallel to the insertion direction of the male connector is arranged on the moving element 50, the embedded block 10 is slidably matched with the intermediate guide rod, the intermediate guide rod is sleeved with an intermediate spring, and the elastic force of the intermediate spring pushes the embedded block 10 and the moving element 50 to separate.

[0030] An intermediate spring is used as an elastic support and is spaced between the embedded block 10 and the moving element 50. When the pin of the male connector is inserted, the pin will push the embedded block 10 to move into the female connector. When the intermediate spring receives the pressure of the embedded block 10, it will elastically contract, and the distance between the embedded block 10 and the moving element 50 will be narrowed, providing space for the movement of the embedded block 10.

[0031] like Figure 2 , 4 As shown in Figure 5, a driving element 40 is fixedly arranged on the fixed frame body 51, and the driving element 40 includes a cylindrical center guide column, a driving spring is arranged in the center guide column, and a "I"-shaped support frame body 30 is slidably matched in the center guide column. The support frame body 30 is connected to a connecting column arranged along the insertion direction of the pin, and a driving plug 31 that is slidably matched with the center guide column is installed at the end of the connecting column. One end of the driving spring abuts against the bottom of the center guide column, and the other end abuts against the driving plug 31. The elastic force of the driving spring is used to push the support frame body 30 away from the bottom of the center guide column.

[0032] More optimally, a fastener is installed on the central guide column to limit the drive plug 31 and prevent the drive plug 31 from being disengaged; its purpose is to facilitate the drive plug 31 to be disengaged from the central guide column during installation and disassembly and maintenance.

[0033] The driving element 40 is used to store the potential energy when the male connector is inserted, and when a line failure occurs, the potential energy released by the driving element 40 is used to push the male connector and the female connector to separate. In the present invention, the following structure is used to convert the potential energy.

[0034] like Figure 2 , 3 As shown in Figures 4 and 5, an upper protrusion 12 is provided on the embedded block 10. When the embedded block 10 moves inward, the upper protrusion 12 is in contact with the support frame body 30, and the embedded block 10 drives the support frame body 30 to move toward the fixed frame body 51; more optimally, the connection between the embedded block 10 and the intermediate guide rod is a resistance portion 13, which is always located at the lower end of the support frame body 30, and when the embedded block 10 extends its stroke outward, the resistance portion 13 is in contact with the bottom of the support frame body 30; its function is to utilize the limiting effect of the support frame body 30 on the resistance portion 13 to constrain the movement stroke of the embedded block 10 and prevent the embedded block 10 from detaching from the female joint.

[0035] like Figure 5 , 6 As shown in Figures 7 and 8, a connecting frame 52 is fixedly provided at the bottom of the moving element 50, and a plurality of moving elements 50 are connected by the connecting frame 52 to realize the synchronous movement of the plurality of moving elements 50 and the plurality of embedded blocks 10; a bottom spring 53 is provided between the support body and the connecting frame 52, and the elastic force provided by the bottom spring 53 is used to push the connecting frame 52 and the moving element 50 to move in the direction of outward extension.

[0036] In the present invention, when the embedded block 10 moves inward under the push of the male connector pin, the embedded block 10 will push the middle spring between the embedded block 10 and the moving element 50 to contract, and will push the bottom spring 53 between the support body and the connecting frame 52 to contract. The contraction of the middle spring and the bottom spring will provide space for the inward movement of the embedded block; at the same time, the upper protrusion 12 on the embedded block 10 pushes the supporting frame body 30 to move inward, so as to increase the potential energy of the driving spring. The increased potential energy of the driving spring will become the driving force for the embedded block 10 to push the male connector pin to separate.

[0037] When the embedding block 10 moves inward under the push of the pin of the male connector, if there is no restrictive structure to impose restrictions, the embedding block 10 will not be able to be stabilized inside the female connector, and the pin of the male connector will not be able to stably contact the energizing element arranged in the female connector. To solve this problem, the present invention also provides a limiting element 60 on the fixed frame 51, and the limiting element 60 is used to control the elastic release timing of the driving spring.

[0038] like Figure 6 , 7As shown in FIG. 8 , two limiting elements 60 are provided and are respectively disposed at one end of the fixed frame body 51. The limiting element 60 includes a limiting base slidably connected to the fixed frame body 51, and a connecting rod 61 is fixedly connected to the limiting base. More optimally, a limiting spring is provided between the fixed frame body 51 and the limiting base, and the elastic force provided by the limiting spring is used to pull the connecting rod 61 to conflict with the fixed frame body 51.

[0039] More specifically, a driving rod 63 fixed to the fixed frame 51 is also provided between the two limiting elements 60, and pistons are slidably matched at both ends of the driving rod 63, and the limiting base is connected to the pistons on the corresponding end sides through the piston rod; more perfectly, a resistor 64 is provided in the driving rod 63. When a line failure occurs, the resistor 64 is energized and can dissipate heat in a relatively short time. The dissipated heat energy will push the pistons at both ends to move outward, thereby pushing the limiting base and the connecting rod 61 to overcome the elastic force of the limiting spring and deviate from the fixed frame 51.

[0040] like Figure 5 , 8 As shown, an inclined pushing base surface 32 is provided on the carrier body 30, and a matching base surface 62 matching the pushing base surface 32 is fixedly provided on the suspended end of the connecting rod 61; when the carrier body 30 moves toward the fixed frame body 51, the pushing base surface 32 will push the matching base surface 62 to move outward, so that the pushing base surface 32 can move to the lower end of the matching base surface 62, and realize the restriction of the matching base surface 62 on the pushing base surface 32; when the two pistons move outward, the matching base surface 62 will eliminate the restriction on the pushing base surface 32, thereby allowing the driving spring to release the elastic potential energy and realize the separation of the male connector pin pushed by the embedded block 10.

[0041] like Fig. 9 As shown, a communicating air hole is provided at the bottom of the center guide column, and is connected with the inner cavity of the driving rod 63 through the communicating air hole. A resistance element 70 is also provided in the center guide column. The resistance element 70 includes an inner sleeve 72 which is connected with the communicating air hole and sleeved on the outside of the communicating air hole. An air blocking plug 73 which can slide along its axial direction is movably provided in the inner sleeve 72. An outer sleeve 71 is sleeved on the outer surface of the inner sleeve 72. A sealing cover is provided on the upper end of the outer sleeve 71 and an air guide hole is provided at the center of the sealing cover. An air guide column 74 matching the air guide hole is provided on the upper end of the air blocking plug 73, and an air guide ring groove 75 is provided on the air guide column 74.

[0042] More optimally, the thickness of the air blocking plug 73 is h, the height of the inner sleeve 72 is H, and h<H<2h; by limiting the size, the movement stroke and stability of the air blocking plug 73 can be better stabilized.

[0043] More specifically, a spacing channel a is provided between the upper end of the inner sleeve 72 and the sealing cover, a spacing channel b is provided between the outer sleeve 71 and the inner sleeve 72, and a vent hole connected to the spacing channel b is provided at the bottom of the center guide column, and the end of the vent hole is connected to the external atmosphere.

[0044] In the initial state of the resistance element 70, the bottom of the air blocking plug 73 fits with the bottom of the center guide column. At this time, the inside of the center guide column is connected to the air vent through the air guide ring groove 75, the spacing channel a, and the spacing channel b; when a line failure occurs and the resistor 64 starts to work, the connecting air hole is connected to the driving rod 63, and the expansion of the air will push the air blocking plug 73 to move upward, and the air guide column 74 will block the air guide hole.

[0045] It should be noted that in the present invention, the role of the resistance element 70 is very important. When a line fault occurs, a closed space is formed inside the center guide column, and the drive plug 31 cannot be displaced inside the center guide column, thereby blocking the insertion of the pin of the male connector. If there is no resistance element 70, the male connector can still be inserted normally and will contact the power-carrying element 20 at the moment of insertion. Even if the contact is not stable, there will still be safety hazards at the moment of contact. Therefore, the blocking effect of the resistance element 70 can be used to further improve the safety performance.

[0046] In order to further improve the safety of electricity use and avoid the wrong insertion of the embedded block 10, the present invention also provides a safety protection structure, through which the safety performance can be further improved. Only when two pins are inserted at the same time, the embedded block 10 can be driven to move inward.

[0047] Specifically, see Appendix Figure 2 , 3 As shown, an inner slider 11 is slidably matched in the embedded block 10, a lifting spring is arranged between the bottom of the embedded block 10 and the inner slider 11, and an interface groove matching the energizing element 20 and used for inserting the energizing element 20 is arranged on the embedded block 10. In detail, the energizing element 20 is a rectangular block and is slidably arranged in the support body. The movement direction of the energizing element 20 is perpendicular to the movement direction of the embedded block 10. A fastening spring is arranged between the energizing element 20 and the support body, and the elastic force provided by the fastening spring is used to push the energizing element 20 toward the embedded block 10.

[0048] More optimally, an inclined transition slope is provided at one end of the power-carrying element 20 facing the embedded block 10, and a guiding slope matching the transition slope is provided at the bottom of the inner slider; when the pin of the male connector is inserted into the inner groove of the embedded block, the pin will push the inner slider 11 to move inward, and push the power-carrying element 20 to disengage from the interface groove provided on the embedded block 10, and as the pin pushes the embedded block 10 to continue to move inward, the pin will contact the power-carrying element 20 and complete the power-on, and under the action of the tightening spring, the power-on stability can be guaranteed; when a line fault occurs, the driving spring can release the elastic potential energy, and the embedded block 10 pushes the male connector pin to disengage.
