Description

Technical Field

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

[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 connection device" with the patent publication number CN209183787U, the movable chuck on the body cooperates with the first check tooth to clamp the wire. After that, the movable chuck improves the reliability of wire installation and connection through the second check tooth to prevent the wire from falling off;

[0004] For example, in the "a sealed terminal block" with the patent publication number CN220710766U, a threaded rod is internally threaded in the upper pipe body and a clamping plate is provided in cooperation, so as to fix and clamp the connecting wire, improve the stability of the connection of the connecting wire, and prevent the connecting wire from falling off;

[0005] However, when clamping through the threaded rod, the wind force in coastal areas is relatively large, which is likely to exert an external force jitter on the threaded rod. The jitter of the threaded rod is likely to cause loosening and a decrease in the clamping force, reducing the reliability and safety of wire connection;

[0006] At the same time, the conductive seat is mostly made of copper or aluminum. The water vapor in coastal areas contains more salts, which is likely to corrode the conductive seat. After the conductive seat is infiltrated by salt mist, salt mist corrosion is likely to occur, which will increase the resistance of the connection point between the conductive seat and the wire, cause serious wire heating, and even cause a fire.

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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.

[0047] Embodiment 1:

[0048] A wire connection device, as Figures 1-6 shown, includes a conductive base 11, a wire clamping block 12, a locking block 13, a first adjusting member 14, a second adjusting member 15, and an insulating sleeve 16. The conductive base 11, the wire clamping block 12, and the locking block 13 are jointly used to fix the wire, and the two wires are electrically connected through the conductive base 11. After the two wires are installed and electrically connected, the insulating sleeve 16 is used to isolate the conductive base 11, the wire clamping block 12, and the locking block 13 from the outside, preventing the conductive base 11, the wire clamping block 12, and the locking block 13 from being corroded by water vapor and also preventing accidental contact and electric shock, thereby improving the safety of the wire connector.

[0049] The conductive base 11 is provided with a first groove 111 and a second groove 112 communicating with the first groove 111. The wire clamping block 12 is slidably arranged up and down in the first groove 111. A wire clamping channel 18 is formed between one end of the wire clamping block 12 and the inner wall of one end of the first groove 111. The wire clamping channel 18 is used for accommodating a wire. The locking block 13 is installed in the second groove 112. The locking block 13 is used for locking the wire clamping block 12. When the wire clamping channel 18 clamps the wire, the locking block 13 locks the wire clamping block 12 to prevent the wire clamping block 12 from sliding, thereby avoiding the wire from falling off the conductive base 11. The first groove 111, the second groove 112, the wire clamping block 12, the locking block 13, the first adjusting member 14, the second adjusting member 15, and the wire hole 1605 are all provided in multiple numbers and correspond to each other one by one. In this embodiment, taking the installation of two wires as an example, therefore, the first groove 111, the second groove 112, the wire clamping block 12, the locking block 13, the first adjusting member 14, the second adjusting member 15, and the wire hole 1605 are all provided in two numbers and correspond to each other one by one.

[0050] The first adjusting member 14 is installed on the conductive base 11. The first adjusting member 14 is used to push the wire clamping block 12 to slide up and down to adjust the size of the wire clamping channel 18. When the wire clamping block 12 approaches the inner wall of one end of the first groove 111, the wire clamping channel 18 increases. When the wire clamping block 12 moves away from the inner wall of one end of the first groove 111, the wire clamping channel 18 decreases, so that the wire clamping channel 18 can clamp wires of different sizes. The second adjusting member 15 is installed on the conductive base 11. The second adjusting member 15 is used to push the locking block 13 to abut against the wire clamping block 12 to lock the wire clamping block 12. Specifically, the direction of the extrusion force exerted by the locking block 13 on the wire clamping block 12 is perpendicular to the sliding direction of the wire clamping block 12. When installing the wire, first drive the first adjusting member 14 so that the width of the wire clamping channel 18 is slightly larger than the wire, then insert the wire into the wire clamping channel 18, and then drive the first adjusting member 14 so that the wire clamping channel 18 decreases until the wire clamping block 12 and the inner wall of the first groove 111 jointly clamp the wire. Finally, drive the second adjusting member 15 so that the locking block 13 abuts against the wire clamping block 12 to lock the wire clamping block 12, preventing the wire clamping block 12 from sliding. Under the action of the locking block 13, the wire reaches the locked state, preventing loosening during use, thereby avoiding the wire from falling out of the wire clamping channel 18 under the action of external force or its own weight. The two wires are installed in different wire clamping channels 18 according to the above process. When one of the wires is energized, the current is transmitted to the other wire through the conductive base 11 to complete the conduction of the two wires.

[0051] To ensure that the conductive base 11, the locking block 13 and the wire clamping block 12 on the conductive base 11 are not corroded by water vapor during use, after the two wires are installed, an insulating sleeve 16 is sleeved outside the conductive base 11, the locking block 13 and the wire clamping block 12 on the conductive base 11. The insulating sleeve 16 is made of insulating materials such as plastic and ceramic. The insulating sleeve 16 has a sleeve cavity 1604 and a wire hole 1605. The insulating sleeve 16 is sleeved on the conductive base 11 through the sleeve cavity 1604. The conductive base 11, the locking block 13 and the wire clamping block 12 are all located in the sleeve cavity 1604. The wire clamping channel 18 communicates with the outside of the insulating sleeve 16 through the wire hole 1605, and it is convenient for the wire to pass through the wire hole 1605.

[0052] The wire connector of the present utility model is convenient to install, can be operated by a single person, and has high working efficiency. The reliability of wire installation and connection can be improved through the locking block 13 and the wire clamping block 12. The insulating sleeve 16 can be used to prevent the wire connector from being corroded, avoiding problems such as an increase in the resistance of the connection point between the conductive base 11 and the wire, serious wire heating, and fire, and improving the reliability and safety of wire connection.

[0053] The second adjusting member 15 includes an elastic member. The elastic member is clamped between the locking block 13 and the inner wall of the second groove body 112. The locking block 13 is located between the elastic member and the wire clamping block 12. The elastic member is preferably a spring. By applying an elastic force to the locking block 13 through the elastic member, the locking block 13 is abutted against the wire clamping block 12. The elastic member utilizes the Hooke's self-locking principle to realize the self-locking function of the locking block 13, and prevents the wire clamping block 12 from loosening during use under the action of the locking block 13.

[0054] In one embodiment, the insulating sleeve 16 includes a main housing and a third housing 1603. Among them, the main housing includes a first housing 1601 and a second housing 1602. The first housing 1601 is connected to the second housing 1602 and jointly forms a first wire groove 1624. The first wire groove 1624 is in a semi-circular arc shape and extends along the horizontal direction. The third housing 1603 has a second wire groove 1625. The second wire groove 1625 is in a semi-circular arc shape and extends along the horizontal direction. When the first housing 1601 and the second housing 1602 are both connected to the third housing 1603, the first housing 1601, the second housing 1602 and the third housing 1603 jointly enclose a sleeve cavity 1604, and the inner walls of the first wire groove 1624 and the second wire groove 1625 jointly enclose a wire hole 1605. Sealing gaskets are arranged opposite to each other on the side walls of the wire hole 1605.

[0055] Optionally, the connection between the first housing 1601, the second housing 1602, and the third housing 1603 is a detachable connection. In this embodiment, the connection between the first housing 1601, the second housing 1602, and the third housing 1603 is achieved by snap connection and pivot connection. The snap connection is the cooperation of a snap block and a slot or the cooperation of a snap hook and a slot, and the pivot connection is the cooperation of a shaft hole and a shaft body. The first housing 1601 has a first engaging portion 1606, the second housing 1602 has a second engaging portion 1607, and the first housing 1601 is connected to the second housing 1602 through the snap connection of the first engaging portion 1606 and the second engaging portion 1607. The first housing 1601 and / or the second housing 1602 has a third engaging portion 1608, the first housing 1601 and / or the second housing 1602 has a first pivoting portion 1610, the third housing 1603 has a second pivoting portion 1611 and a fourth engaging portion 1609 for snap connection with the third engaging portion 1608. Specifically, a first snap hook is provided at the first engaging portion 1606, a first slot is provided at the second engaging portion 1607, and the first snap hook is snap-connected to the first slot. The third engaging portion 1608 and the first pivoting portion 1610 are provided on both the first housing 1601 and the second housing 1602. A first snap block is provided at the third engaging portion 1608, and a second slot is provided at the fourth engaging portion 1609. Two lugs are arranged at intervals at the first pivoting portion 1610, and a shaft hole is provided on the lugs. A shaft body is provided at the second pivoting portion 1611. The third housing 1603 is rotatably installed in the shaft hole on the first housing 1601 and the second housing 1602. The third housing 1603 can rotate relative to the first housing 1601 and the second housing 1602. The first pivoting portion 1610 is pivotally connected to the second pivoting portion 1611, and the third engaging portion 1608 is located on the rotation path of the fourth engaging portion 1609. When installing the insulating sleeve 16, the wire is made to fall into the first wire groove 1624. First, align the first snap hook of the first engaging portion 1606 with the first slot of the second engaging portion 1607, then align the shaft hole of the first pivoting portion 1610 with the shaft body of the second pivoting portion 1611. Then, while snapping the first snap hook into the first slot, make the shaft body snap into the shaft hole. Finally, rotate the third housing 1603 to make the first snap block snap into the second slot to complete the installation of the insulating sleeve 16.

[0056] The wire hole 1605 improves the sealing performance with the wire through a sealing gasket.

[0057] Furthermore, there are multiple third housings 1603. The multiple third housings 1603 correspond to the multiple wire clamping blocks 12 one by one. The multiple third housings 1603 are all installed on the first housing 1601 and the second housing 1602 to form multiple wire holes 1605.

[0058] Optionally, in order to achieve the matching between the conductive seat 11 and the insulating sleeve 16 and improve the installation efficiency, a convex strip 1612 is provided in both the first shell 1601 and the second shell 1602, and a strip groove 113 for the convex strip 1612 to be inserted into is provided on the conductive seat 11. When the first shell 1601 and the second shell 1602 wrap the conductive seat 11, the convex strip 1612 is inserted into the strip groove 113.

[0059] In one embodiment, the first adjusting member 14 and the locking block 13 are located on two adjacent sides of the wire clamping block 12 , and the second adjusting member 15 is located on a side of the locking block 13 away from the wire clamping block 12 .

[0060] The first adjusting member 14 includes a first screw rod 141 , and the second adjusting member 15 includes a second screw rod 151 . The axis of the first screw rod 141 is perpendicular to the axis of the second screw rod 151 . Specifically, the spring is sleeved on the second screw rod 151 .

[0061] The conductive seat 11 is provided with a first threaded hole connected to the first slot body 111 and a second threaded hole connected to the second slot body 112. The first screw rod 141 is threaded through the first threaded hole and is movably connected to the clamping block 12. The second screw rod 151 is threaded through the second threaded hole and abuts against the locking block 13. The clamping block 12 is sleeved on the end of the first screw rod 141. When the first screw rod 141 rotates, it moves along its own axial direction, thereby pushing or pulling the clamping block 12 to move. Specifically, the first screw rod 141 drives the clamping block 12 to move up and down in the vertical direction, and one side of the locking block 13 abuts and cooperates with the end of the second screw rod 151. The second screw rod 151 pushes the locking block 13 in the horizontal direction to abut on the clamping block 12, thereby locking the clamping block 12.

[0062] Optionally, the insulating sleeve 16 further includes a first sealing cap 1613 and a second sealing cap 1614. The main housing is provided with a first rod hole 1615 and a second rod hole 1616. Specifically, the first housing 1601 or the second housing 1602 or the first housing 1601 and the second housing 1602 together form the first rod hole 1615 and the second rod hole 1616. That is, the first rod hole 1615 can be formed on the first housing 1601, or on the second housing 1602, or partly on the first housing 1601 and partly on the second housing 1602. Similarly, the second rod hole 1616 can be formed on the first housing 1601, or on the second housing 1602, or partly on the first housing 1601 and partly on the second housing 1602. This facilitates the passing of the first screw rod 141 and the second screw rod 151. The first adjusting member 14 further has a first rod head 142 connected to the first screw rod 141, and the second adjusting member 15 further has a second rod head 152 connected to the second screw rod 151. When the third housing 1603 rotates, the first rod head 142 and the second rod head 152 can be exposed outside the sleeve cavity 1604, facilitating the driving of the first adjusting member 14 and the second adjusting member 15 to rotate to adjust the locking force. Therefore, the insulating sleeve 16 can be pre-installed on the conductive base 11 and then the wire can be installed.

[0063] The first screw rod 141 sequentially passes through the first rod hole 1615 and the first threaded hole, and the second screw rod 151 sequentially passes through the second rod hole 1616 and the second threaded hole. A connecting pipe 1617 is annularly provided at the edge of the first rod hole 1615. A part of the connecting pipe 1617 is located in the first housing 1601 and is integrally formed with the first housing 1601, and another part of the connecting pipe 1617 is located in the second housing 1602 and is integrally formed with the second housing 1602. The connecting pipe 1617 communicates with the sleeve cavity 1604 through the first rod hole 1615. The first sealing cap 1613 is detachably installed on the connecting pipe 1617 and jointly encloses with the connecting pipe 1617 to form a first sealing cavity for accommodating the first rod head 142. The installation of the first sealing cap 1613 on the connecting pipe 1617 closes the opening of the connecting pipe 1617, preventing the first rod head 142 from being exposed to water vapor corrosion during use and improving safety. The second sealing cap 1614 is provided on the third housing 1603 and is integrally formed with the third housing 1603. When the third engaging portion 1608 and the fourth engaging portion 1609 are engaged, the second sealing cap 1614 abuts against the outer sides of the first housing 1601 and the second housing 1602. The second sealing cap 1614 and the first housing 1601 and the second housing 1602 jointly enclose a second sealing cavity for accommodating the second rod head 152. At this time, the second sealing cap 1614 just closes the second rod hole 1616, preventing the second rod head 152 from being exposed to water vapor corrosion during use and improving safety.

[0064] In one embodiment, the first sealing cap 1613 has a first receiving groove 1621, and a positioning protrusion 1622 is provided on the inner wall of the first receiving groove 1621. On the outer side surface of the connecting pipe 1617, a first guiding groove 1618 extending along the axial direction of the first screw 141 and a second guiding groove 1619 extending along the circumferential direction of the first screw 141 are provided. A positioning groove 1620 is provided on the inner wall of the second guiding groove 1619. The first guiding groove 1618 communicates with the second guiding groove 1619. The positioning protrusion 1622 on the first sealing cap 1613 slides from the first guiding groove 1618 into the second guiding groove 1619 and is snapped into the positioning groove 1620. When installing the first sealing cap 1613, first snap the positioning protrusion 1622 into the first guiding groove 1618 along the axial direction of the first screw 141, then snap the positioning protrusion 1622 into the second guiding groove 1619 along the circumferential extension of the first screw 141, and finally make the positioning protrusion 1622 snap into the positioning groove 1620 to complete the installation of the first sealing cap 1613. The second sealing cap 1614 has a second receiving groove 1626. When the third housing 1603 rotates to make the third engaging portion 1608 engage with the fourth engaging portion 1609, the second sealing cap 1614 is sleeved on the second rod head 152 through the second receiving groove 1626 to protect the second rod head 152.

[0065] In one embodiment, a marking portion 1623 is provided on the outer side surface of the first sealing cap 1613, and the marking portion 1623 and the positioning protrusion 1622 are arranged in sequence along the radial direction of the first screw 141. A scale bar can be provided at the marking portion 1623, or a protrusion or a groove can be provided. In this embodiment, a boss is provided at the marking portion 1623, and the boss can be used to identify whether the positioning protrusion 1622 is snapped into the positioning groove 1620. In addition, the boss can also play an anti-slip role to facilitate the rotation of the first sealing cap 1613.

[0066] In one embodiment, both the first groove 111 and the second groove 112 penetrate through the conductive base 11 along a predetermined straight line direction. The predetermined straight line direction, the axial direction of the first screw 141, and the axial direction of the second screw 151 are perpendicular to each other pairwise. The wire clamping block 12 is snapped into the first groove 111 along the predetermined straight line direction and slides in the first groove 111 along the axial direction of the first screw 141. The locking block 13 is snapped into the second groove 112 along the predetermined straight line direction and abuts against the wire clamping block 12 along the axial direction of the second screw 151. The wire clamping block 12 and the locking block 13 are respectively installed in the first groove 111 and the second groove 112 from the predetermined straight line direction, which is convenient for installation.

[0067] In one embodiment, the wire connector further includes an anti - detachment sleeve 17 having a sleeve groove 171. The anti - detachment sleeve 17 is located within the sleeve cavity 1604. The anti - detachment sleeve 17 is sleeved on the conductive base 11 through the sleeve groove 171 and covers the notch of the first groove body 111 and the notch of the second groove body 112. Both the wire - clamping block 12 and the locking block 13 are located within the sleeve groove 171. By providing the anti - detachment sleeve 17, it is possible to prevent the wire - clamping block 12 and the locking block 13 from detaching from the conductive base 11 from the first groove body 111 and the second groove body 112 respectively.

[0068] In one embodiment, the conductive base 11, the wire - clamping block 12, and the locking block 13 are all conductive metal parts. The conductive base 11, the wire - clamping block 12, and the locking block 13 are preferably made of aluminum alloy, which has good electrical conductivity and corrosion resistance. One side of the wire - clamping block 12 located in the wire - clamping channel 18 is provided with an arc surface 121. The first groove body 111 has an arc inner wall 114. The arc surface 121 and the arc inner wall 114 are oppositely arranged and jointly enclose the wire - clamping channel 18. The second groove body 112 has an arc segment 115. The locking block 13 has an arc portion 131 and an abutting portion 132 connected to the arc portion 131. The arc portion 131 is rotatably installed within the arc segment 115, facilitating the abutting portion 132 to actively abut against the wire - clamping block 12. The second adjusting member 15 abuts against the abutting portion 132, and the wire - clamping block 12 is located on the rotation path of the abutting portion 132. By surrounding the wire with the arc surface 121 and the arc inner wall 114, the contact area between the wire and the wire can reach 2 to 4 times the cross - sectional area of the conductor, meeting the over - current requirements of large loads.

[0069] Furthermore, barbs are provided on both the inner wall of the first groove body 111 of the conductive base 11 and the outer surface of the wire - clamping block 12. The barbs on the conductive base 11 and the barbs on the wire - clamping block 12 slide relative to each other. When the wire - clamping block 12 pushes and clamps the wire, the first adjusting member 14 continues to apply force to further clamp the wire by the wire - clamping block 12, causing partial deformation of the wire. At this time, the deformation causes the wire - clamping block 12 to generate a reaction force acting on the first adjusting member 14. The locking block 13 will prevent the wire - clamping block 12 from moving in the opposite direction under the action of the spring, so that the barbs of the fixed conductive base 11 and the barbs of the wire - clamping block 12 are engaged together to reach a self - locking state, which can prevent the wire connector from loosening during use and ensure the over - current capacity of the wire connector. When the wire connector needs to be removed, first, unlock the second adjusting member 15 to compress the spring, reducing the extrusion force of the locking block 13 on the wire - clamping block 12, and then rotate the first adjusting member 14 to drive the wire - clamping block 12 to the initial state.

[0070] The insulating sleeve 16 has different specifications, and different insulating sleeves 16 are set with different colors for easy identification and classification.

[0071] Embodiment Two:

[0072] It includes all the content of Embodiment One, with the difference that, as Figure 7As shown, an activity channel is formed between adjacent two side walls of the conductive base 11. One end of the activity channel extends to the side of the wire clamping block 12 with the arc surface 121, and the other end of the activity channel extends to the side that abuts and cooperates with the locking block 13. A push block 123 is slidably connected in the activity channel. The moving direction of the push block 123 in the activity channel is consistent with the axis of the second screw rod 151. A flexible bag 122 is arranged in the activity channel, and fine sand is contained in the flexible bag 122.

[0073] When the wire is formed by twisting multiple small wires, its surface is uneven.

[0074] Rotate the first screw rod 141 to push the wire clamping block 12 to move upward, so that the arc surface 121 of the wire clamping block 12 tightly abuts against the wire to achieve pre-clamping. Then rotate the second screw rod 151 to push the abutting portion 132 of the locking block 13 to abut against the push block 123, thereby pushing the push block 123 to move a short distance to the right. The movement of the push block 123 pushes the flexible bag 122 filled with fine sand to move in the activity channel, so that one end of the flexible bag 122 moves to abut against the wire. The flexible bag 122 can be deformed to fit on the uneven surface of the wire. At this time, both ends of the flexible bag 122 in the activity channel are clamped by the push block 123 and the wire and cannot be deformed arbitrarily.

[0075] The push block 123 has a certain length to ensure that it can always abut and cooperate with the abutting portion 132 of the locking block 13 during the up and down movement of the wire clamping block 12;

[0076] The wire is first clamped by the wire clamping block 12, and then the flexible bag 122 is attached to the uneven surface of the wire, greatly increasing the contact area between the wire clamping block 12 and the wire and greatly increasing the friction force.
