Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a wire connector. Background Art

[0002] In the existing power system, wire connectors are often used, and the conductive seats of the wire connectors are used to conductively connect two or more wires.

[0003] For example, in the "A General Wire Connecting Device" with the patent publication number CN209183787U, the moving clamp head on the body cooperates with the first check tooth to clamp the wire. After that, the moving clamp head improves the reliability of wire installation and connection through the second check tooth again to prevent the wire from falling off; the double clamping improves the fixing effect of the wire.

[0004] The wire clamping groove for clamping the wire is linear and is prone to detachment, so a V-shaped wire clamping groove appears.

[0005] For example, in the "A Side-Groove Clamp" with the patent publication number CN219833059U, the upper cover and the base are buckled with each other to form a wire clamping groove for clamping the wire. The wire clamping groove is in a V-shaped structure to bend the wire to improve the clamping effect.

[0006] However, the V-shaped wire clamping groove is not convenient for passing the wire through the wire clamping groove before clamping. It is necessary to drive the upper cover to move a long distance. After the wire clamping groove is expanded to a certain extent, the wire can pass through the V-shaped wire clamping groove linearly conveniently.

[0007] At the same time, the water vapor in coastal areas contains more salts, which is easy to corrode the conductive seat. The conductive seat is prone to salt spray corrosion after being infiltrated by salt spray, which will increase the resistance of the connection point between the conductive seat and the wire, cause the wire to heat seriously, and even cause a fire.

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0056] Embodiment:

[0057] A wire connector, as Figure 1-10 shown, includes a conductive base 11, a first conductive clamping seat 12, a first adjusting member 13, a second conductive clamping seat 14, a second adjusting member 15 and an insulating sleeve 16. The conductive base 11 is made of conductive metal, and the first conductive clamping seat 12 and the second conductive clamping seat 14 are also made of conductive metal, which can improve the current-carrying performance of the conductor.

[0058] The conductive base 11 is provided with a first groove 111, a second groove 112, and a wire passing hole 113 communicating with the second groove 112. The first groove 111 penetrates the conductive base 11 along the horizontal direction, and the main wire 20 can pass through the first groove 111 along the horizontal direction. The second groove 112 extends along the vertical direction, and the branch wire 30 can penetrate into the second groove 112 from the wire passing hole 113 along the vertical direction.

[0059] The first conductive clamping seat 12 is arranged in the first groove body 111. A first wire clamping channel 17 is formed between the first conductive clamping seat 12 and the inner wall of the first groove body 111. The main wire 20 passes through the first wire clamping channel 17 along the horizontal direction. The first adjusting member 13 is installed on the conductive base 11 and is used to drive the first conductive clamping seat 12 to slide so as to adjust the size of the first wire clamping channel 17. By changing the size of the first wire clamping channel 17, clamping and fixing of main wires 20 with different diameters are achieved.

[0060] The second conductive clamping seat 14 has a first rotating block 141 and a second rotating block 142 which are hinged to each other. The second groove body 112 is located above the wire passing hole 113. The first rotating block 141 and the second rotating block 142 are both rotatably installed in the second groove body 112. The first rotating block 141 and the second rotating block 142 can rotate relative to each other in the second groove body 112 and can move up and down. The first rotating block 141, the second rotating block 142 and the inner wall of the second groove body 112 jointly enclose a second wire clamping channel 18 which is communicated with the wire passing hole 113. The branch wire 30 can pass through the wire passing hole 113 and be inserted into the second wire clamping channel 18. A clamping portion 143 is formed at the hinged part of the first rotating block 141 and the second rotating block 142. The clamping portion 143 is located in the second wire clamping channel 18. The clamping portion 143 is arranged opposite to one side wall of the second groove body 112.

[0061] The second adjusting member 15 is installed on the conductive base 11 and is used to drive the first rotating block 141 and the second rotating block 142 to rotate relative to each other so as to adjust the distance between the clamping portion 143 and the inner wall of the second groove body 112. By driving the first rotating block 141 and the second rotating block 142 to rotate relative to each other through the second adjusting member 15, the clamping portion 143 and the inner wall of the second groove body 112 jointly clamp the branch wire 30.

[0062] The insulating sleeve 16 has a sleeve cavity 1601, a first wire passing hole 1602 and a second wire passing hole 1603 which are both communicated with the sleeve cavity 1601. The insulating sleeve 16 is a cover body formed by insulating materials such as plastic and ceramic. The insulating sleeve 16 is sleeved outside the conductive base 11 through the sleeve cavity 1601. The conductive base 11, the first conductive clamping seat 12, the second conductive clamping seat 14, the first adjusting member 13 and the second adjusting member 15 are all located in the sleeve cavity 1601 of the insulating sleeve 16. The first wire passing hole 1602 is communicated with the first wire clamping channel 17. The main wire 20 passes through the first wire passing hole 1602 and the first wire clamping channel 17. The second wire passing hole 1603 is communicated with the second wire clamping channel 18. The branch wire 30 passes through the second wire passing hole 1603 and the wire passing hole 113 and penetrates into the second wire clamping channel 18.

[0063] In use, the insulating sleeve 16 can be first installed on the conductive base 11, and then the first conductive clip seat 12 is driven by the first adjusting member 13 so that the main wire 20 is clamped in the first wire clamping channel 17, and then the second conductive clip seat 14 is driven by the second adjusting member 15 so that the branch wire 30 is clamped in the second wire clamping channel 18. Alternatively, the insulating sleeve 16 can be put on after the main wire 20 is clamped in the first wire clamping channel 17 and the branch wire 30 is clamped in the second wire clamping channel 18.

[0064] In this way, the clamping and fixing and conduction of the main wire 20 and the branch wire 30 are realized through the first wire clamping channel 17 and the second wire clamping channel 18, and the insulating sleeve 16 is used to protect the conductive base 11, the first conductive clip seat 12, the second conductive clip seat 14, the first adjusting member 13, and the second adjusting member 15, preventing the conductive base 11 from being corroded and improving the reliability and safety of wire connection.

[0065] There are multiple second adjusting members 15, second grooves 112, second conductive clip seats 14, and wire passing holes 113, which correspond to each other one by one. In this way, clamping of multiple branch wires 30 can be realized, enabling the main wire 20 to conduct current to multiple branch wires 30.

[0066] In another embodiment, a first wire groove 1411 is provided on the first rotating block 141, and a second wire groove 1421 is provided on the second rotating block 142. The inner walls of the first wire groove 1411, the second wire groove 1421, and the inner wall of the second groove 112 together enclose the second wire clamping channel 18. The first wire groove 1411 is located on the side of the first rotating block 141 and penetrates the first rotating block 141 from top to bottom. There are multiple first wire grooves 1411, which are arranged at intervals along the horizontal direction. Similarly, the second wire groove 1421 is located on the side of the second rotating block 142 and penetrates the second rotating block 142 from top to bottom. There are multiple second wire grooves 1421, which are arranged at intervals along the horizontal direction. The multiple first wire grooves 1411 and the multiple second wire grooves 1421 correspond to each other one by one. The first rotating block 141 is located above the second rotating block 142. The axes of rotation of the first rotating block 141 relative to the conductive base 11, the axes of rotation of the first rotating block 141 relative to the second rotating block 142, and the axes of rotation of the second rotating block 142 relative to the conductive base 11 are all horizontally arranged and are spaced apart from top to bottom in sequence. When the first rotating block 141 rotates relative to the second rotating block 142, the clamping portion 143 can approach or move away from the inner wall on one side of the second groove 112, thereby realizing the clamping or release of the branch wire 30.

[0067] It can be understood that the first wire groove 1411 and the second wire groove 1421 can also be formed on the inner wall of the second groove body 112. Additionally, a part of the first wire groove 1411 can be provided on the first rotating block 141, and another part is formed on the inner wall of the second groove body 112. A part of the second wire groove 1421 can be provided on the second rotating block 142, and another part is formed on the inner wall of the second groove body 112.

[0068] Optionally, the first wire clamping channel 17 extends along a first straight track. The main wire 20 passes through the first wire clamping channel 17 along the first straight track. The first straight track is horizontally arranged, and the axial direction of the main wire 20 is the same as the extending direction of the first wire clamping channel 17. The wire passing hole 113 extends along a second straight track. The second straight track is vertically arranged. The branch wire 30 passes through the second wire clamping channel 18 along the second straight track. The axial direction of the branch wire 30 is the same as the extending direction of the second wire clamping channel 18. The first straight track and the second straight track are skew lines. The first adjusting member 13 pushes the first conductive clamping seat 12 to move along a horizontal direction perpendicular to the first straight track. The second adjusting member 15 pushes the first rotating block 141 and the second rotating block 142 to rotate relative to each other along a horizontal direction perpendicular to the first straight track. The main wire 20 and the branch wire 30 are arranged in a T shape.

[0069] The second adjusting member 15 has a release state and a locking state. When the second adjusting member 15 is in the release state, it is in a state of releasing the branch wire 30. The branch wire 30 can be inserted into or pulled out of the second wire clamping channel 18. At this time, the second wire clamping channel 18 extends along the second straight track, that is, the second wire clamping channel 18 extends along the vertical direction. By pushing and pulling the branch wire 30 up and down, the branch wire 30 can be inserted into or pulled out of the second wire clamping channel 18. When the second adjusting member 15 is in the locking state, it can clamp the branch wire 30, and the second wire clamping channel 18 extends along a bent track. Specifically, the second wire clamping channel 18 extends along a V-shaped or S-shaped track. The clamping portion 143 and the inner wall of the second groove body 112 on the conductive base 11 jointly clamp the branch wire 30. At the same time, since the second wire clamping channel 18 extends along the bent track, the branch wire 30 is not easily pulled out when subjected to an external pulling force, and the branch wire 30 is not easily dropped, improving the clamping force on the branch wire 30. This not only improves the safety of the installation of the branch wire 30 but also increases the contact area between the branch wire 30 and the conductive base 11 and the second conductive clamping seat 14, improving the current-carrying capacity.

[0070] In this way, the wire connection device of the present utility model not only has a strong clamping force but also has good current-carrying performance. Especially when a typhoon occurs in coastal areas, it can prevent accidents such as wire breakage and wire dropping caused by the typhoon, avoiding power interruption and seriously affecting people's lives and production.

[0071] In order to improve the current carrying capacity and installation stability of the main conductor 20, the first slot body 111 has a first arc surface 117, and the first conductive clamp seat 12 is provided with a second arc surface 121. The first arc surface 117 and the second arc surface 121 are arranged opposite to each other. When the first conductive clamp seat 12 moves, the first arc surface 117 and the second arc surface 121 approach or move away from each other. The first arc surface 117 and the second arc surface 121 are used to clamp the main conductor 20. The first arc surface 117 and the second arc surface 121 increase the contact area between the main conductor 20 and the conductive base 11 and the first conductive clamp seat 12, thereby improving the current carrying performance. The contact between the main conductor 20 and the conductive base 11 and the first conductive clamp seat 12 adopts an embracing design, and the contact between the branch conductor 30 and the conductive base 11 and the second conductive clamp seat 14 also adopts an embracing design, so that the conductor contact area can reach 2 to 4 times the conductor cross-sectional area, which can meet the current carrying requirements of large loads.

[0072] The first rotating block 141 has a first connection end 1412 and a second connection end 1413. The first connection end 1412 is the upper end of the first rotating block 141, and the second connection end 1413 is the lower end of the first rotating block 141. The second rotating block 142 has a third connection end 1422 and a fourth connection end 1423. The third connection end 1422 is the upper end of the second rotating block 142, and the fourth connection end 1423 is the lower end of the second rotating block 142. The first connection end 1412 of the first rotating block 141 and the fourth connection end 1423 of the second rotating block 142 are both rotatably installed in the second groove body 112. An arc groove 1414 is provided at the second connection end 1413 of the first rotating block 141, a rotating shaft 1424 is provided at the third connection end 1422 of the second rotating block 142, and a clamping portion 143 is formed on the rotating shaft 1424. The rotating shaft 1424 is rotatably installed in the arc groove 1414. The first connection end 1412 and the second groove body 112 are in interference fit and / or the fourth connection end 1423 and the second groove body 112 are in interference fit and / or the rotating shaft 1424 and the arc groove 1414 are in interference fit. Within a certain external force range, the second conductive clamping seat 14 can achieve self-locking through interference fit, improving the stability of the second conductive clamping seat 14 for clamping the branch wire 30. Specifically, arc inner walls 119 are provided at both the upper end and the lower end of the second groove body 112. The first connection end 1412 and the fourth connection end 1423 are both arc outer sides, and the first connection end 1412 and the fourth connection end 1423 are respectively rotatably installed at the upper end and the lower end of the second groove body 112. There are three types of interference fits, and one or more of them can be used in combination. Among them, the first type is the interference fit between the first connection end 1412 and the second groove body 112. The second type is the interference fit between the fourth connection end 1423 and the second groove body 112, and the third type is the interference fit between the rotating shaft 1424 and the arc groove 1414. In this way, even if the second screw 151 of the second adjusting member 15 is loosened, the branch wire 30 will not become loose, and the stress generated by the thermal expansion and contraction of the branch wire 30 and the wire connector can be eliminated, ensuring that the branch wire 30 and the wire connector always maintain the best connection state and ensuring that they will not become loose during operation.

[0073] The first adjusting member 13 has a first screw 131. The second adjusting member 15 has a second screw 151. A first threaded hole 114 matching the first screw 131 and a second threaded hole 115 matching the second screw 151 are provided on the conductive base 11. The first threaded hole 114 communicates with the first groove body 111, and the second threaded hole 115 communicates with the second groove body 112. The first screw 131 is screwed through the first threaded hole 114 and is connected to the first conductive clamping seat 12 in the first groove body 111. The first conductive clamping seat 12 is sleeved on the end of the first screw 131, and by rotating the first screw 131, the first conductive clamping seat 12 can be driven to clamp the main wire 20.

[0074] The second connection end 1413 of the first rotating block 141 is provided with a first thread groove 1415, and the third connection end 1422 of the second rotating block 142 is provided with a second thread groove 1425. The inner walls of the first thread groove 1415 and the second thread groove 1425 jointly enclose a third thread hole 144 that matches the second screw rod 151;

[0075] The second screw rod 151 sequentially passes through the second thread hole 115 and the third thread hole 144. By rotating the first screw rod 131, the second conductive clip seat 14 can be driven to clamp the split wire 30.

[0076] Before clamping: The first rotating block 141 and the second rotating block 142 are in a substantially flush state. At this time, the inner contour of the third thread hole 144 formed by enclosing the first thread groove 1415 and the second thread groove 1425 is larger than the outer contour of the second screw rod 151 and they are not engaged;

[0077] During clamping: Rotate the second screw rod 151. The first rotating block 141 and the second rotating block 142 are relatively rotated under the extrusion of the second screw rod 151, and the first rotating block 141 and the second rotating block 142 form a V-shaped structure;

[0078] After clamping, the first rotating block 141 and the second rotating block 142 that form a V-shaped structure cooperate to fix the split wire 30 in the second wire clamping channel 18; at the same time, the third thread hole 144 formed by enclosing the first thread groove 1415 and the second thread groove 1425 is engaged with the second screw rod 151.

[0079] During clamping, the second screw rod 151 is threadedly engaged with both the third thread hole 144 and the second thread hole 115 at the same time to improve the loosening effect.

[0080] Further, the first thread groove 1415 is installed on the first rotating block 141 through a corresponding elastic pad, and the second thread groove 1425 is installed on the second rotating block 142 through a corresponding elastic pad. The elastic pads all have a certain elastic deformation ability. When clamping split wires 30 with different outer diameters, the first rotating block 141 and the second rotating block 142 form V-shaped structures with different angles. At this time, through the automatic adjustment of the thickness of the elastic pads, the first thread groove 1415 and the second thread groove 1425 can still be engaged with the second screw rod 151.

[0081] On the inner wall of the sleeve cavity 1601, there is an avoidance groove 1605 located on the moving path of the second screw rod 151. The avoidance groove 1605 provides an avoidance position for the second screw rod 151 to prevent interference when the second screw rod 151 moves.

[0082] Furthermore, the first rotating block and the second rotating block have self-locking ability after installation. Even if the second screw 151 is removed, the branch conductor 30 will not loosen, and the overcurrent will not be affected. Sufficient overcurrent capacity is guaranteed, and later maintenance costs are eliminated. In order to improve the locking ability of the first screw 131, the first screw 131 is treated with a special anti-loosening screw glue to prevent loosening during use. The contact part between the wire connector and the wire adopts an embracing structure design. The main wire and the branch wire are installed independently and do not affect each other. The first adjustment member 13 and the second adjustment member 15 of the wire connector are also independent of each other to avoid mutual interference between the lines during use. The first adjustment member 13 and the second adjustment member 15 are bolts of the same specification, which are convenient for installation and use.

[0085] After the first shell 1606 and the second shell 1607 are assembled, a first pivoting portion 1616, a second pivoting portion 1617, and a third wire groove 1620 are formed. The first shell 1606 is provided with a first hanging ear 1628 having an axis hole, and the second shell 1607 is provided with a second hanging ear 1629 having an axis hole, and the first hanging ear 1628 and the second hanging ear 1629 are combined to form the first pivoting portion 1616, the first shell 1606 is provided with a third hanging ear 1630 having an axis hole, and the second shell 1607 is provided with a fourth hanging ear 1631 having an axis hole, and the third hanging ear 1630 and the fourth hanging ear 1631 are combined to form the second pivoting portion 1617.

[0086] The third housing 1608 has a third pivoting portion 1618, a fifth engaging portion 1614, a sixth engaging portion 1615, and a fourth wire groove 1621. The fifth engaging portion 1614 and the sixth engaging portion 1615 have the same structure, and both the fifth engaging portion 1614 and the sixth engaging portion 1615 are provided with a first engaging block and a second engaging block. The third pivoting portion 1618 is a first shaft body, and the first shaft body is installed in the shaft holes of the first hanging ear 1628 and the second hanging ear 1629.

[0087] The third pivoting portion 1618 is pivotally connected to the first pivoting portion 1616. The third engaging portion 1612 is located on the rotation path of the fifth engaging portion 1614, and the fourth engaging portion 1613 is located on the rotation path of the sixth engaging portion 1615. When the third engaging portion 1612 is engaged with the fifth engaging portion 1614 and the fourth engaging portion 1613 is engaged with the sixth engaging portion 1615, the inner walls of the third wire groove 1620 and the fourth wire groove 1621 jointly enclose a first wire passing hole 1602, and a second wire passing hole 1603 is formed by opening on the first housing 1606 or the second housing 1607, or the first housing 1606 and the second housing 1607 jointly enclose the second wire passing hole 1603. The second wire passing hole 1603 can be opened on the first housing 1606, or can be opened on the second housing 1607. The second wire passing hole 1603 can also have a part opened on the first housing 1606 and another part opened on the second housing 1607.

[0088] The fourth housing 1609 has a fourth pivoting portion 1619 pivotally connected to the second pivoting portion 1617 and a second positioning portion 1623 engaged with the first positioning portion 1622.

[0089] Thus, when the insulating sleeve 16 is sleeved on the upper end of the conductive base 11, first align the first engaging portion 1610 of the first housing 1606 with the third engaging portion 1612 of the second housing 1607, then align the third pivoting portion 1618 of the third housing 1608 with the first pivoting portion 1616, and align the fourth pivoting portion 1619 of the fourth housing 1609 with the second pivoting portion 1617. Then, the first engaging portion 1610 and the third engaging portion 1612 are engaged, at this time, the third pivoting portion 1618 is exactly pivotally connected to the first pivoting portion 1616, and the fourth pivoting portion 1619 is pivotally connected to the second pivoting portion 1617, so that the first housing 1606, the second housing 1607, the third housing 1608, and the fourth housing 1609 wrap the conductive base 11. Finally, rotate the third housing 1608 and the fourth housing 1609. When the third engaging portion 1612 is engaged with the fifth engaging portion 1614 and the fourth engaging portion 1613 is engaged with the sixth engaging portion 1615, the installation of the third housing 1608 is completed. When the first positioning portion 1622 and the second positioning portion 1623 are engaged, the installation of the fourth housing 1609 is completed. When it is necessary to adjust the clamping or releasing of the wire by the first conductive clip seat 12 and the second conductive clip seat 14, rotate the fourth housing 1609 to separate the first positioning portion 1622 and the second positioning portion 1623, so that one end of the first adjusting member 13 and one end of the second adjusting member 15 are exposed, thereby driving the first adjusting member 13 and the second adjusting member 15 to rotate.

[0090] Optionally, the conductive base 11 is provided with a rib 118, and both the first housing 1606 and the second housing 1607 are provided with a strip-shaped groove 1632 into which the rib 118 is inserted. Through the strip-shaped groove 1632 and the rib 118, it is convenient to position the first housing 1606 and the second housing 1607 when they are sleeved on the conductive base 11.

[0091] Optionally, the third housing 1608 further has a supporting portion 1624, the fourth wire groove 1621 is opened in the supporting portion 1624, the third pivoting portion 1618 is connected to the supporting portion 1624, and both the fifth engaging portion 1614 and the sixth engaging portion 1615 are rotatably connected to the supporting portion 1624.

[0092] Both the fifth engaging portion 1614 and the sixth engaging portion 1615 have a first position and a second position. When the fifth engaging portion 1614 is in the first position, the third engaging portion 1612 is engaged with the fifth engaging portion 1614. When the sixth engaging portion 1615 is in the first position, the fourth engaging portion 1613 is engaged with the sixth engaging portion 1615. When the fifth engaging portion 1614 is in the second position, the third engaging portion 1612 is separated from the fifth engaging portion 1614. When the sixth engaging portion 1615 is in the second position, the fourth engaging portion 1613 is separated from the sixth engaging portion 1615.

[0093] When the third housing 1608 is mounted on the first housing 1606 and the second housing 1607, the fifth engaging portion 1614 and the sixth engaging portion 1615 are rotated so that the third engaging portion 1612 is engaged with the fifth engaging portion 1614 and the fourth engaging portion 1613 is engaged with the sixth engaging portion 1615, thereby realizing the installation of the third housing 1608. Since the third housing 1608 is rotatably mounted on the first housing 1606 and the second housing 1607, if both the fifth engaging portion 1614 and the sixth engaging portion 1615 are fixed, a very high machining accuracy is required. Otherwise, it is easy to cause the third engaging portion 1612 and the fifth engaging portion 1614 to fail to engage and the fourth engaging portion 1613 and the sixth engaging portion 1615 to fail to engage. Therefore, by providing the rotatable fifth engaging portion 1614 and the sixth engaging portion 1615, it is convenient to realize the engagement between the third engaging portion 1612 and the fifth engaging portion 1614 and the engagement between the fourth engaging portion 1613 and the sixth engaging portion 1615, facilitating the installation of the third housing 1608.

[0094] Optionally, both the fifth engaging portion 1614 and the sixth engaging portion 1615 are connected to the support portion 1624 through the bending portion 1625. The bending portion 1625 can be bent and deformed. By using the bending deformation of the bending portion 1625, both the fifth engaging portion 1614 and the sixth engaging portion 1615 are rotated around the support portion 1624, realizing the engagement between the third engaging portion 1612 and the fifth engaging portion 1614 and the engagement between the fourth engaging portion 1613 and the sixth engaging portion 1615.

[0095] Furthermore, the fourth housing 1609 has a specific receiving groove 1626. When the first positioning portion 1622 is engaged with the second positioning portion 1623, the inner wall of the receiving groove 1626, the first housing 1606, the second housing 1607, and the third housing 1608 jointly enclose a sleeve cavity 1601. The first adjusting member 13 has a first driving head 132 located in the receiving groove 1626, and the first adjusting member 13 has a second driving head 152 located in the receiving groove 1626. The first driving head 132 and the second driving head 152 facilitate the installer to drive the first screw 131 and the second screw 151 to rotate by hand. After the main wire 20 and the branch wire 30 are installed, the fourth housing 1609 covers the first driving head 132 and the second driving head 152 to achieve sealing, preventing the first driving head 132 and the second driving head 152 from being accidentally touched and also preventing the first driving head 132 and the second driving head 152 from being corroded.

[0096] The fourth housing 1609 can be snap-fitted with the first positioning portion 1622 and the second positioning portion 1623. The insulating sleeve 16, the conductive base 11, the first conductive clamping seat 12, the second conductive clamping seat 14, the first adjusting member 13, and the second adjusting member 15 are pre-assembled into a whole, eliminating the need for on-site assembly. Tightening the first adjusting member 13 and the second adjusting member 15 realizes the installation of the main wire 20 and the branch wire 30, which is simple and convenient to operate. The insulating sleeve 16 is color-coded according to the phase sequence colors of the wires, facilitating installation and phase sequence identification. The main wire 20 and the branch wire 30 are respectively locked, facilitating installation, enabling live operation, and having high working efficiency. There are four types of model specifications for the wire connection device, meeting the installation and use requirements of wires with a cross-sectional area of 6 - 300 mm 2 to facilitate type selection and reduce inventory pressure. The insulating sleeve 16 is of a fully enclosed type, with a high anti-electric shock level, color-coded by phase, and is standard, safe, and beautiful.

[0097] Furthermore, a wire plug 1627 is detachably installed on the insulating sleeve 16. The second wire passing hole 1603 has an outlet 1604, and the wire plug 1627 covers at least a part of the outlet 1604. The wire plug 1627 is provided on the outer side surface of the insulating sleeve 16 and is connected to the insulating sleeve 16 through a plastic sheet. The wire plug 1627, the plastic sheet, and the insulating sleeve 16 are integrally formed by plastic. When the branch wire 30 needs to be passed through the second wire passing hole 1603, the wire plug 1627 can be separated from the insulating sleeve 16 by an external force. The wire plug 1627 is retained in the unused second wire passing hole 1603, thus preventing the second wire passing hole 1603 from being blocked before it is used. Different second wire passing holes 1603 can be set with different diameters to meet the clamping of branch wires 30 with different diameters.

[0098] Optionally, an extension hole 116 is provided on the conductive base 11. The second wire clamping channel 18 is located between the extension hole 116 and the wire passing hole 113. The two ends of the second wire clamping channel 18 are respectively communicated with the extension hole 116 and the wire passing hole 113. In this way, the branch wire 30 sequentially passes through the wire passing hole 113, the second wire clamping channel 18, and the extension hole 116. The extension hole 116 increases the insertion length of the branch wire 30, improves the clamping stability of the branch wire 30 and the contact area between the branch wire 30 and the conductive base 11, and improves the current-carrying capacity.
