Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a wiring method for connecting terminals, terminal blocks and power distribution terminals. Background Technology

[0002] Distribution terminals are a general term for various remote monitoring and control units installed in the power distribution network. Distribution terminals perform functions such as data acquisition, control and communication, and mainly include feeder terminals, station terminals, and transformer terminals.

[0003] During wiring, power distribution terminals need to be connected to external wires via connection terminals. In existing technology, the connection terminal includes a main housing and a conductive plate disposed within the main housing. The main housing has a insertion slot; the wire is inserted into the insertion slot and secured in place by a spring-loaded clip, allowing the wire to contact the conductive plate within the main housing and achieve electrical connection. However, this existing technology has the following drawback: the connection terminal only uses a spring-loaded clip to limit and fix the wire, resulting in insufficient stability. Summary of the Invention

[0004] The objective of this invention is to provide a connection terminal. 、 The wiring method for terminal blocks and power distribution terminals offers high stability and efficiency.

[0005] To achieve this objective, the embodiments of the present invention adopt the following technical solutions:

[0006] In a first aspect, a connection terminal is provided, comprising:

[0007] An insulating body includes a main housing, the main housing being provided with a mounting cavity and a plug-in slot, the plug-in slot communicating with the mounting cavity, and the plug-in slot being used for wire insertion;

[0008] A limiting structure is provided within the mounting cavity. The limiting structure includes a driving pressure member, a clamping member, and a conductive member. The driving pressure member is rotatably disposed within the mounting cavity. The conductive member is spaced apart on one side of the driving pressure member. The clamping member is connected to the driving pressure member and is at least partially located within the insertion slot. The driving pressure member can rotate to press the wire onto the conductive member and can drive the clamping member to clamp the wire.

[0009] An electrical connector, which is electrically connected to the conductive element.

[0010] As a preferred embodiment of the connection terminal, the clamping member includes a limiting clamp ball and a pushing member. At least two limiting grooves are recessed on the groove wall of the insertion groove. All the limiting grooves are arranged in a ring along the groove wall of the insertion groove. The length extension direction of the limiting groove is consistent with the length extension direction of the insertion groove, and the bottom of the limiting groove is inclined. The bottom of the limiting groove is inclined from the end near the insertion groove toward the end away from the insertion groove toward the side opposite to the mounting cavity. The limiting clamp ball is movably disposed in the limiting groove. The pushing member is connected to the driving pressure member. When the driving pressure member rotates, the pushing member can push the limiting clamp ball to move along the length direction of the limiting groove in the limiting groove, so that all the limiting clamp balls can come close to each other to clamp the wire.

[0011] As a preferred embodiment of the connection terminal, the pushing member includes a pushing plate and a first elastic member. The first elastic member connects the pushing plate and the driving pressure member. The pushing plate is provided with a clearance hole for avoiding the wire. The pushing plate is provided with a pushing part protruding circumferentially. The pushing part is inserted into the limiting groove and is used to push the limiting clamping ball to move.

[0012] As a preferred embodiment of the connection terminal, the limiting structure further includes a clamping member, which is connected to the driving clamping member. The rotation centers of the clamping member and the driving clamping member are spaced apart, and the driving clamping member can drive the clamping member to extend into the insertion slot and press it against the outer wall of the wire.

[0013] As a preferred embodiment of the connection terminal, the clamping member includes a clamping rod, a clamping seat, and a second elastic member. One end of the clamping rod is hinged in the mounting cavity, and the other end is a first free end. The clamping seat is movably disposed at the non-end of the clamping rod. The driving clamping member rotates to drive the clamping rod to rotate, thereby causing the end of the clamping seat away from the clamping rod to extend into the insertion slot to clamp the wire. The second elastic member is connected to the clamping seat, and the second elastic member always has a tendency to drive the clamping seat away from the insertion slot.

[0014] As a preferred embodiment of the connection terminal, the driving pressure member includes an arc-shaped convex ring and a driving rod connected to the arc-shaped convex ring. The arc-shaped convex ring is hinged in the mounting cavity and can press the wire onto the conductive member.

[0015] As a preferred embodiment of the connection terminal, the conductive element includes a third elastic element, a conductive sheet, and a power base. The power base is disposed within the mounting cavity. One end of the conductive sheet is electrically connected to the power base. The end of the conductive sheet away from the power base is a third free end. The third elastic element is connected to the third free end. The third elastic element always has a tendency to drive the third free end toward the driving pressure element.

[0016] As a preferred embodiment of the connection terminal, the main housing is provided with at least two mounting cavities and two insertion slots, each mounting cavity is provided with a limiting structure, and all the conductive components are connected through the electrical connector.

[0017] In a second aspect, a terminal block is provided, including a mounting plate and at least two of the aforementioned connection terminals, wherein the insulating body of the connection terminal includes a main housing and a retaining plate disposed on one side of the main housing, and all the retaining plates are secured to the mounting plate.

[0018] Thirdly, a wiring method for a power distribution terminal is provided, comprising the aforementioned terminal block, and the wiring method for this power distribution terminal includes the following steps:

[0019] Step S100: Select a matching number of connection terminals for the terminal block based on the number of pins of the power distribution terminal;

[0020] Step S200: Secure all the connection terminals to the mounting plate of the terminal block;

[0021] Step S300: Disconnect the circuit of the connection terminal;

[0022] Step S400: Provide a first wire and a second wire that need to be wired. Insert the ends of the first wire and the second wire that need to be connected into the two plug slots of the same connection terminal respectively. Then, move the driving pressure member of the connection terminal to lock the first wire and the second wire into the plug slots.

[0023] Step S500: Repeat step S400 until all the pins are wired.

[0024] Step S600: Turn on the circuit of the connection terminal.

[0025] The beneficial effects of this invention are as follows: The connecting terminal utilizes a rotating driving pressure member within the mounting cavity, connecting a clamping member to the driving pressure member. When a wire is inserted into the insertion slot, rotating the driving pressure member presses the wire against the conductive element, achieving an electrical connection between the wire and the conductive element. Simultaneously, the rotation of the driving pressure member drives the clamping member to clamp the wire. This dual fixation of the wire by the driving pressure member and the clamping member ensures the stability of the wire within the insertion slot. Furthermore, during wiring, rotating the driving pressure member to clamp the wire simultaneously drives the clamping member to clamp the wire, simplifying operation and improving the wiring efficiency of the connecting terminal.

Detailed Implementation

[0037] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] like Figures 1 to 7 As shown, the connection terminal of this embodiment of the invention includes an insulating body 1, a limiting structure, and an electrical connector 5. The insulating body 1 includes a main housing 11, which is provided with a mounting cavity 111 and a plug-in groove 112. The plug-in groove 112 communicates with the mounting cavity 111 and is used for inserting the wire 100. The limiting structure is disposed in the mounting cavity 111 and includes a driving pressure member 2, a clamping member 3, and a conductive member 4. The driving pressure member 2 is rotatably disposed in the mounting cavity 111, and the conductive member 4 is spaced apart on one side of the driving pressure member 2. The clamping member 3 is connected to the driving pressure member 2 and is at least partially located in the plug-in groove 112. The rotation of the driving pressure member 2 can press the wire 100 onto the conductive member 4 and can drive the clamping member 3 to clamp the wire 100. The electrical connector 5 is electrically connected to the conductive member 4.

[0041] In this embodiment, the connection terminal uses a rotatable driving pressure member 2 within the mounting cavity 111, with a clamping member 3 connected to the driving pressure member 2. When a wire 100 is inserted into the insertion slot 112, rotating the driving pressure member 2 presses the wire 100 against the conductive member 4, achieving an electrical connection between the wire 100 and the conductive member 4. Simultaneously, the rotation of the driving pressure member 2 also drives the clamping member 3 to clamp the wire 100. This dual fixation of the wire 100 by the driving pressure member 2 and the clamping member 3 ensures the stability of the wire 100 within the insertion slot 112. Furthermore, during wiring, rotating the driving pressure member 2 to press the wire 100 simultaneously drives the clamping member 3 to clamp the wire 100, simplifying operation and improving the wiring efficiency of the connection terminal.

[0042] In this embodiment, the driving pressure member 2 has an initial state and a locking state. The initial state refers to the state before the wire 100 is inserted into the plug slot 112 and before insertion. The locking state refers to the state in which the wire 100 is locked in the plug slot 112 by rotating the driving pressure member 2 after the wire 100 is inserted into the plug slot 112.

[0043] In this embodiment, the driving pressure member 2 includes an arc-shaped convex ring 21 and a driving rod 22 connected to the arc-shaped convex ring 21. The arc-shaped convex ring 21 is hinged in the mounting cavity 111 and can press the wire 100 onto the conductive member 4. The arc-shaped convex ring 21 has a hinge center and a variable diameter structure. Its outer side wall has anti-slip teeth to increase the friction with the side wall of the wire 100. As the driving rod 22 deflects from a vertical state, the arc radius of the arc-shaped convex ring 21 gradually increases. It can be understood that in the initial state, the arc-shaped convex ring 21 is facing or in contact with the wire 100 at a position with a smaller arc radius. During wiring, the driving rod 22 can be manually swung to rotate the arc-shaped convex ring 21. As the position of the outer side wall of the arc-shaped convex ring 21 changes, it eventually presses against the wire 100 at a position with a larger arc radius, causing the driving pressure member 2 to enter a locked state.

[0044] In one optional embodiment, the end of the drive rod 22 away from the arc-shaped convex ring 21 is the second free end. When the drive pressure member 2 is in the locked state, the second free end is lower than the hinge center of the arc-shaped convex ring 21. This design can utilize the lever principle to make the drive pressure member 2 have a stable locking effect.

[0045] In another alternative embodiment, Figure 4 and Figure 5 As shown, the clamping member 3 includes a limiting clamping ball 31 and a pushing member 32. At least two limiting grooves 113 are recessed on the groove wall of the insertion groove 112. All the limiting grooves 113 are arranged in a ring along the groove wall of the insertion groove 112. The length extension direction of the limiting groove 113 is consistent with the length extension direction of the insertion groove 112. The bottom of the limiting groove 113 is inclined. The bottom of the limiting groove 113 is inclined from the end near the insertion groove 112 toward the end away from the insertion groove 112 toward the side away from the mounting cavity 111. In other words, the inclined surface of the bottom of the limiting groove 113 gradually approaches the center line of the insertion groove 112 in the direction of approaching the groove opening of the insertion groove 112. The limiting clamping balls 31 are movably disposed within the limiting groove 113. The pushing member 32 is connected to the driving pressure member 2. The pushing member 32 can push the limiting clamping balls 31 to move along the length of the limiting groove 113 within the limiting groove 113, so that each limiting clamping ball 31 approaches each other radially and clamps onto the wire 100. In this structure, the special structure of the limiting groove 113 allows each limiting clamping ball 31 to approach each other during the pushing process, thereby clamping wires 100 of different sizes, making it widely applicable.

[0046] It is understandable that in actual application scenarios, there will be wires 100 of different diameters. Therefore, the size of the insertion slot 112 can usually accommodate wires 100 of different sizes. When the push plate 321 pushes the limiting clamp ball 31 to move, the limiting clamp ball 31 stops moving when it moves to the position of pressing against the side wall of the wire 100. Therefore, the limiting clamp ball 31 can move to different positions in the limiting slot 113 according to the different sizes of the wires 100, thereby achieving the pressing of wires 100 of different sizes.

[0047] Specifically, the pushing member 32 includes a pushing plate 321 and a first elastic member 322. The first elastic member 322 connects the pushing plate 321 and the driving pressure member 2. The pushing plate 321 has a through-hole 3212 for avoiding the wire 100, and the diameter of the through-hole 3212 is the same as that of the insertion slot 112, so that the pushing plate 321 will not block the wire 100 when it is inserted into the insertion slot 112. The pushing plate 321 has a circumferentially protruding pushing part 3211, which is inserted into the limiting slot 113 and used to push the limiting clamping ball 31 to move. The second elastic member 63 is used to maintain the position of the pushing plate 321, and the second elastic member 63 has a retractable space to satisfy the function of the limiting clamping ball 31 to clamp wires 100 of different sizes. It should be noted that during the wiring process, the rotational distance of the second free end of the drive rod 22 is usually constant, but the distance that the drive rod 22 drives the limiting clamp ball 31 to move within the limiting groove 113 varies (the clamping position of the limiting clamp ball 31 within the limiting groove 113 varies depending on the diameter of the wire 100). Therefore, the second elastic element 63 can adjust the travel margin of the drive rod 22 and the limiting clamp ball 31.

[0048] Optionally, the second elastic element 63 is a spring.

[0049] Optionally, the limiting clamp ball 31 is a sphere, and the limiting clamp ball 31 is disposed within the limiting groove 113. In other embodiments, the limiting clamp ball 31 has a structure such as an ellipsoid or a cylinder.

[0050] It should be noted that the limiting clamp ball 31 can extend into the insertion slot 112 so that the limiting clamp ball 31 can contact the wire 100. The width of the opening of the limiting slot 113 is smaller than the diameter of the limiting clamp ball 31. Therefore, the limiting clamp ball 31 cannot detach from the limiting slot 113 during movement. An installation port is provided at one end of the opening of the limiting slot 113. The size of the installation port is larger than the size of the limiting clamp ball 31, so that the limiting clamp ball 31 can be inserted into the limiting slot 113 from the installation port.

[0051] In an optional embodiment, such as Figure 4As shown, the limiting structure also includes a clamping member 6, which is connected to the driving clamping member 2. The rotation centers of the clamping member 6 and the driving clamping member 2 are spaced apart. The driving clamping member 2 can drive the clamping member 6 to extend into the insertion slot 112 and press it against the outer wall of the wire 100 to maintain the tension state between the wire 100 and the clamping member 3. At the same time, the driving clamping member 2 can rotate to achieve triple clamping of the wire 100, which can improve the wiring stability of the connection terminal without adding wiring steps.

[0052] Specifically, such as Figure 3 As shown, the mounting cavity 111 includes a first mounting groove 1111, a second mounting groove 1112, a third mounting groove 1113, and a fourth mounting groove 1114. The driving pressure member 2 is rotatably disposed within the first mounting groove 1111. The second mounting groove 1112 and the third mounting groove 1113 are spaced apart and both communicate with the first mounting groove 1111. The fourth mounting groove 1114 is located below the insertion groove 112. The shape of each mounting groove is set according to the structure and function of the component to be installed.

[0053] The clamping component 6 includes a pressure rod 61 and a pressure seat 62. One end of the pressure rod 61 is hinged in the third mounting groove 1113, and the other end is a first free end extending into the first mounting groove 1111. The pressure seat 62 is movably disposed at the non-end of the pressure rod 61, with the end of the pressure seat 62 away from the pressure rod 61 extending into the insertion groove 112. The driving component 2 rotates to drive the pressure rod 61 to rotate, thereby causing the pressure seat 62 to clamp the wire 100. As the driving component 2 transitions from the initial state to the locked state, the driving rod 22 gradually presses the pressure rod 61 downward, causing the pressure rod 61 to rotate around its hinged end, thereby causing the pressure seat 62 to move downward and extend into the insertion groove 112 to clamp the wire 100. Since the wire 100 has already been clamped and limited by the limiting clamping ball 31, when it is further squeezed by the pressure seat 62, the wire 100 will produce a small displacement in the compression direction, which will further improve the clamping effect of the clamping component 3. It is understandable that the third mounting groove 1113 is a triangular groove, and one end of the pressure rod 61 is hinged to the corner of the triangular groove away from the first mounting groove 1111. The triangular groove can provide swing space for the pressure rod 61, and the groove wall of the triangular groove can limit the pressure rod 61 to prevent the pressure rod 61 from rotating excessively.

[0054] Specifically, the clamping member 6 includes a second elastic member 63, which is connected to the pressure seat 62. The second elastic member 63 always has a tendency to drive the pressure seat 62 away from the insertion slot 112. When the drive rod 22 is separated from the pressure rod 61, the second elastic member 63 can drive the pressure rod 61 to rotate upward so as to drive the pressure seat 62 out of the insertion slot 112 for the next wiring.

[0055] Furthermore, a first moving groove and a second moving groove perpendicular to the first moving groove are provided through the pressure rod 61, and the length extension directions of the first moving groove and the second moving groove are consistent. A protrusion is provided on the pressure seat 62, and the protrusion is movably disposed in the first moving groove. The second elastic member 63 is connected to the protrusion. A protruding post is provided on the opposite side of the protrusion, and the protruding post is movably disposed in the second moving groove. When the pressure rod 61 rotates, the protrusion moves in the first moving groove, so as to drive the pressure seat 62 to move away from or closer to the wire 100.

[0056] Optionally, the second elastic element 63 is a spring, with one end of the spring connected to the groove wall of the third mounting groove 1113 and the other end connected to the protrusion.

[0057] In another optional embodiment, the conductive element 4 includes a third elastic element 41, a conductive sheet 42, and a terminal block 43. The terminal block 43 is disposed within the mounting cavity 111. One end of the conductive sheet 42 is electrically connected to the terminal block 43, and the end of the conductive sheet 42 away from the terminal block 43 is a third free end. The third elastic element 41 is connected to the third free end, and the third elastic element 41 always has a tendency to drive the third free end to move closer to the driving pressure element 2. The conductive sheet 42 is located below the arc-shaped convex ring 21. When the wire 100 is inserted into the insertion slot 112, the driving rod 22 drives the arc-shaped convex ring 21 to rotate, so that the area with a larger radius of the arc-shaped convex ring 21 presses the wire 100 downward. At the same time, the third elastic element 41 drives the conductive sheet 42 to press the wire 100 upward, so as to ensure the insertion stability of the wire 100 in the insertion slot 112 and improve the electrical conductivity stability. Optionally, the third elastic element 41 can be a spring or an elastic pad; the conductive sheet 42 is a conductive metal sheet. On the one hand, the metal sheet has good conductivity; on the other hand, the metal sheet cooperates with the spring to make the third free end of the conductive element 4 have good extension performance so that the wire 100 has a good clamping effect.

[0058] It should be noted that the wire 100 includes a conductor portion and a sheath portion. The area without a protective sheath on the outer surface of the conductor is the conductor portion, and the area with a protective sheath on the outer surface of the conductor is the sheath portion. The conductive element 4 is electrically connected to the conductor portion.

[0059] Furthermore, the main housing 11 is provided with at least two mounting cavities 111 and two insertion slots 112. Each mounting cavity 111 is provided with a limiting structure, and each insertion slot 112 is used to insert a wire 100. All conductive components 4 are connected by electrical connectors 5. In this embodiment, the main housing 11 has a symmetrical structure, with two mounting cavities 111 and two insertion slots 112 symmetrically arranged, corresponding to the input and output parts of the connection terminals, respectively. Two wires 100 can be inserted into the two insertion slots 112 respectively and connected to the conductive components 4 respectively. The electrical connectors 5 electrically connect the two terminals 43, thereby realizing the connection of the two wires 100.

[0060] Specifically, the electrical connector 43, the third elastic element 41, and the conductive sheet 42 are all disposed in the fourth mounting groove 1114, and the third free end of the conductive sheet 42 can extend into the insertion groove 112.

[0061] The electrical connector 5 includes an electrical connector 51 and an adjusting bolt 52 threadedly connected to the electrical connector 51; the end of the electrical connector 51 extends into the electrical base 43 and is able to contact the conductor portion within the electrical base 43.

[0062] Electrical connector 5 is used to connect the conductor portions of two sets of wires 100, so that the two parts form a connected circuit or a broken circuit. Specifically, the electrical connector 51 is a sheet-shaped conductive body with a bolt hole in its middle. The adjusting bolt 52 is threaded through the bolt hole and rotatably connected to the side wall of the main housing 11 to adjust the connection position of the electrical connector 51. When both ends of the electrical connector 51 are in contact with the conductor portion in the junction box 43, the circuit at both ends of the electrical connector 51 is connected; otherwise, the circuit at both ends is disconnected.

[0063] The present invention also discloses a terminal block, including a mounting plate 7 and at least two connection terminals in any of the above embodiments. The insulating body 1 of the connection terminal includes a main housing 11 and a retaining plate disposed on one side of the main housing 11. All retaining plates can be snapped onto the mounting plate 7.

[0064] In this embodiment, the terminal block adopts a separate design for the mounting plate 7 and the connecting terminals. During actual installation, an appropriate number of connecting terminals can be selected according to requirements, making it applicable to a wide range of scenarios. Furthermore, the connecting terminals are secured in the slots of the mounting plate 7 via clips, making assembly and disassembly convenient. The connecting terminal block utilizes the cooperation of the driving pressure component 2 and the clamping component 3. When the driving pressure component 2 is rotated to press the wire 100, the clamping component 3 simultaneously clamps the wire 100, simplifying operation and improving the wiring efficiency and stability of the connecting terminals.

[0065] Optionally, the mounting plate 7 is provided with guide rails 71 on both sides along the width direction, and the card plate is provided with a slot corresponding to the guide rail 71, and the card plate is locked onto the guide rail 71 through the slot.

[0066] like Figures 1-7 As shown, the present invention also provides a wiring method for a power distribution terminal, providing a terminal block as described in the above embodiments, including the following steps:

[0067] Step S100: Select the corresponding number of terminal blocks for connection based on the number of pins in the power distribution terminal.

[0068] Step S200: Secure all the connection terminals onto the mounting plate 7 of the terminal block;

[0069] Step S300: Disconnect the circuit of the connection terminal to ensure the safety of the wiring;

[0070] Step S400: Provide the first wire 110 and the second wire 120 that need to be wired. Insert the ends of the first wire 110 and the second wire 120 that need to be connected into the two plug slots 112 of the connection terminal respectively. Then, move the driving pressure member 2 of the connection terminal to lock the first wire 110 and the second wire 120 into the plug slots 112.

[0071] Step S500, repeat step S400 until all pins are wired;

[0072] Step S600: Connect the circuit to the terminal.

[0073] The wiring method of the power distribution terminal of the present invention can select an appropriate number of connection terminals according to the number of pins of the power distribution terminal to adapt to different needs. In the process of wiring the first wire 110 and the second wire 120, the wire 100 can be triple-locked by simply driving the driving pressure member 2 to rotate, so as to ensure the stability of the wire 100 in the plug slot 112 and improve the wiring efficiency.

[0074] In the actual wiring process, first select the number of connection terminals that match the number of pins of the power distribution terminal to be connected; fix the mounting plate 7 with screws through the fixing holes of the mounting plate 7 according to the installation position; then install the connection terminals by holding the main housing 11 of the connection terminal and making the slots on both sides of the card plate lock into the guide rail 71 on the mounting plate 7; then disconnect the electrical connector 5 by releasing the adjusting bolt 52 to separate the electrical connector 5 from the conductor part in the terminal block 43 to ensure the safety of the terminal block wiring.

[0075] After initializing the driving pressure member 2, in other words, moving the driving pressure member 2 to its initial state; the driving rod 22 is moved to deflect the arc-shaped convex ring 21 so that the arc-shaped convex ring 21 does not obstruct the insertion slot 112, and then the wire 100 is inserted; because the driving rod 22 is deflected, the driving rod 22 does not squeeze the second free end of the pressure rod 61, and thus, under the action of the second elastic member 63, the pressure seat 62 exits the cavity of the insertion slot 112, and does not obstruct the cavity of the insertion slot 112; while the pushing plate 321 is pulled to move within the limiting groove 113 under the action of the first elastic member 322, that is, from the end of the limiting groove 113 with a smaller radial diameter to the end with a larger radial diameter. The insertion slot 112 is completely cleared, facilitating the insertion process of the wire 100.

[0076] In the initial wiring of conductor 100, the first conductor 110 is led out from the power distribution terminal, and the end of the first conductor 110 is inserted into the plug slot 112. At this time, the conductor part of the first conductor 110 contacts and connects with the third free end of the first conductive sheet 42. Then, the drive rod 22 is turned to engage. When the drive rod is turned, the arc-shaped convex ring 21 rotates around the hinge center. Due to the irregular contact of the arc-shaped convex ring 21, as the degree of engagement of the pressure plate increases, the contact between the arc-shaped convex ring 21 and the conductor 100 increases, and the degree of compression of the side wall of the conductor 100 by the arc-shaped convex ring 21 is greater, which will push the conductor 100 to contact the conductive sheet 42 more tightly.

[0077] As the drive rod 22 deflects, the first elastic element 322 pushes the push plate 321 to move within the limiting groove 113, and pushes the limiting clamp ball 31 to move within the limiting groove 113, that is, from the end with the larger radial diameter of the limiting groove 113 to the end with the smaller radial diameter. During the process, when the limiting clamp ball 31 contacts the side wall of the wire 100, the limiting clamp ball 31 stops moving, and under the action of the push plate 321, the limiting clamp ball 31 is stably limited. The advantage of this structure is that it can adapt to wires 100 of different diameters, and at this time it is more difficult to pull the wire 100 out of the insertion groove 112 from the outside, achieving a very stable locking effect and preventing the wire 100 from detaching from the connection terminal.

[0078] Furthermore, when the deflecting drive rod 22 contacts the second free end of the pressure rod 61, it will push the pressure rod 61 to rotate in the third mounting groove 1113, and move through the protrusion in the first moving groove and the protrusion in the second moving groove, thereby pressing the pressure seat 62 against the outer wall of the wire 100, further improving the clamping effect of the clamping member 3.

[0079] After the wire 100 is connected, the position of the electrical connector 5 can be controlled by adjusting the bolt 52 to connect or disconnect the conductive circuit of the connection terminal.

[0080] When it is necessary to release the wire 100, the drive rod 22 is pulled open again, and the clamping member 3 and the pressing member 6 are disengaged from the wire 100. At this time, the wire 100 can be easily pulled out from the plug slot 112.
