Technical Field

[0001] The present invention relates to the technical field of connection structures, and particularly to a connector for fixing an angle steel tower line. Background Art

[0002] As a core infrastructure in fields such as power transmission, communication base stations, and bridge supports, the structural stability and safety of an angle steel tower directly affect the reliability and service life of the overall project. In the construction of transmission lines, angle steel towers are widely used to erect high-voltage and extra-high-voltage lines, undertaking the important task of supporting conductors, insulator strings, and fittings. The line connector on the angle steel tower is the main structure for connecting conductors, which can butt and fix two conductors to prevent the wound positions from separating and disconnecting from each other.

[0003] Common connectors are mainly snap-type or extrusion locking type. The snap-type connector clamps two conductors to prevent them from loosening. When using this type of connector, workers still need to wind the two conductors together, and its use convenience is poor. The extrusion locking type connector mainly directly clamps and fixes the exposed metal wires on two conductors to achieve line connection. However, this method can only achieve frictional fixation of the metal wires, that is, the metal wires are prone to bifurcation, wire breakage, and loosening, and its connection is not firm. Summary of the Invention

[0005] Further, a plurality of conductive sleeves on the semi-compression column are arranged along the length direction of the semi-compression column.

[0006] Further, a plurality of ribs are arranged on the conductive sleeve.

[0007] Further, the positions of the corresponding ribs on the two semi-compression columns are staggered.

[0008] Further, a stopper for positioning the semi-compression column protrudes from both end faces of each arc-shaped seat, and the stopper can be flattened or squeezed into the inner side of the arc-shaped seat.

[0009] Further, a plug board is arranged on each arc-shaped seat, and the arc-shaped seat can be slidably connected to the shell through the plug board. The plug board and the shell are connected by an elastic body; Among them, a support body for extruding the outer wall of the semi-pressing column is arranged in each of the shells.

[0010] Furthermore, arc-shaped strips are arranged in each of the shells, a plurality of locking holes are formed in the arc-shaped strips, a plurality of locking rods cooperating with the locking holes are arranged on the semi-pressing column, and when the semi-pressing column moves along its own axis direction, the locking rods are inserted into or removed from the corresponding locking holes.

[0011] Furthermore, the two shells are connected by a plurality of soft sheets, and the two shells and the plurality of soft sheets are integrally processed.

[0012] Furthermore, a plurality of long grooves are oppositely formed in one of the shells, a plurality of inclined platforms are arranged in the long grooves, and a plurality of hook strips cooperating with the inclined platforms in each of the long grooves are arranged on the other shell.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. This embodiment is written in a progressive manner.

[0020] As Figures 1 to 5 shown, a connector for fixing an angle steel tower line of the present invention includes two shells 1 that can be buckled with each other and half-pressure columns 3 arranged on each shell 1. Both ends of the half-pressure column 3 extend to the outside of the shell 1, and the half-pressure column 3 can rotate on the shell 1 through two arc-shaped seats 2. A conductive sleeve 4 is arranged on each half-pressure column 3; In the present invention, one shell 1 and one half-pressure column 3 are used in combination to form a group. The straight line where the half-pressure column 3 is located is parallel to the plane where the shell 1 is located. Arc-shaped seats 2 are inlaid on two side walls at opposite positions on the shell 1. The half-pressure column 3 is rotatably arranged in the two arc-shaped seats 2. The two half-pressure columns 3 can be butted with each other when the two shells 1 are closed. In this way, the two half-pressure columns 3 can form a complete column shape, and the two arc-shaped seats 2 at corresponding positions can be butted to form a ring, so that the column can rotate in the ring; the conductive sleeve 4 is mainly used to provide a placement position for the wire, and when the two half-pressure columns 3 are butted, the conductive sleeves 4 on the two half-pressure columns 3 can clamp the wire between them; During use, place the stripped ends of two wires at the position of the conductive sleeves 4 on a semi-pressing post 3. The two wires can be inserted into the space between the two housings 1 in the same direction or inserted into the space between the two housings 1 opposite to each other left and right. After the wires are placed, close the two housings 1. At this time, the two semi-pressing posts 3 are butted synchronously, and the two opposite conductive sleeves 4 on the two semi-pressing posts 3 clamp and fix the wire ends therebetween. Then rotate the two semi-pressing posts 3 to wind the wires around the column formed by the two semi-pressing posts 3, that is, wind more exposed parts of the wires around the conductive sleeves 4, thereby realizing the connection of the circuit; By connecting the wires in the way of first clamping and then winding, the connection strength of the wires can be effectively improved, the connection method can be simplified, the cumbersome operation during manual winding of the wires can be avoided, the convenience of using the structure can be conveniently improved, and at the same time, phenomena such as splitting, wire breakage, and loosening of the metal wires at the ends of the wires can be avoided; It should be noted that since the wires need to be pressed and wound around the conductive sleeves 4, the two wires can achieve a conductive connection effect through the conductive sleeves 4 without directly connecting the two wires, which is convenient for connection and avoids the cumbersome operation of accurately docking the two wire ends; since the conductive sleeves 4 on the two semi-pressing posts 3 need to clamp the wire ends, the wire ends will occupy a part of the space between the two conductive sleeves 4; to facilitate the insertion of the wires into the housing 1, wire holes can be provided on the housing 1.

[0021] Furthermore, a plurality of conductive sleeves 4 on the semi-pressing post 3 are arranged along the length direction of the semi-pressing post 3; To realize the connection of multiple wires, the multiple wires can be divided into several groups, and two wires to be connected are set in each group. In this way, the two wires in each group can be connected by means of a conductive sleeve 4 on the semi-pressing post 3, and the multiple conductive sleeves 4 on the two semi-pressing posts 3 can realize the connection of multiple groups of wires, thereby reducing the number of connectors used, reducing the wiring complexity, improving the space utilization rate, and being able to complete the multi-wire connection in a single operation, saving the installation time.

[0022] Furthermore, a plurality of ribs 5 are arranged on the conductive sleeve 4; By arranging a plurality of ribs 5 on the conductive sleeve 4, the friction effect between the conductive sleeve 4 and the wire end can be enhanced by using the ribs 5, thereby improving the clamping effect; the arrangement direction of the plurality of ribs 5 needs to be parallel to the length direction of the wire, and the length direction of the ribs 5 needs to be perpendicular to the length direction of the wire; It should be noted that the cross-sectional shape of the rib 5 can be any shape such as an arc shape or a square shape. On the premise of avoiding squeezing the wire end, any shape of the rib 5 that helps to improve the clamping effect is within the protection scope of this case.

[0023] Further, to improve the clamping effect of the conductive sleeve 4 on the wire head, the positions of the corresponding ribs 5 on the two half compression columns 3 are staggered. In this way, when the two half compression columns 3 are butted, several ribs 5 on the corresponding two conductive sleeves 4 can be butted staggeredly, thereby pressing the wire head into a continuous bent shape; In some embodiments, one rib 5 on one of the corresponding two conductive sleeves 4 can be used in cooperation with one rib 5 on the other conductive sleeve 4, that is, there are multiple docking areas of ribs 5 between the two conductive sleeves 4. In this way, the two conductive sleeves 4 can perform multi-point clamping work on the wire head. Also, one rib 5 on one conductive sleeve 4 can be used in cooperation with two adjacent ribs 5 on the other conductive sleeve 4, that is, one rib 5 can have two clamping points.

[0024] Further, on both end faces of each arc-shaped seat 2, there protrudes a stopper 6 for positioning the half compression column 3, and the stopper 6 can be flattened or squeezed into the inner side of the arc-shaped seat 2; Since the two half compression columns 3 need to be butted, the corresponding two arc-shaped seats 2 also need to be butted. Therefore, without setting other structures, the half compression column 3 can directly break away from the arc-shaped seat 2, which causes the scattering of the structure. To avoid this phenomenon, stoppers 6 can be provided at both ends of the arc-shaped seat 2 to block the half compression column 3 with the stoppers 6, so that the half compression column 3 is kept within the arc-shaped seat 2; the blocking method of the stopper 6 can be to directly block on the plane of the half compression column 3, or the radian of the overall shape formed by the arc-shaped seat 2 and the two stoppers 6 is greater than a semi-circle, thereby allowing the half compression column 3 to rotate, but restricting it within the arc-shaped seat 2; When the two half compression columns 3 are butted, the corresponding two arc-shaped seats 2 are butted synchronously, and the stoppers 6 on the two arc-shaped seats 2 will be squeezed. The stopper 6 can be deformed and flattened to ensure the smooth butting of the two arc-shaped seats 2. Of course, a receiving groove can also be opened at the end of the arc-shaped seat 2, and the stopper 6 is arranged on the receiving groove. When the stopper 6 is squeezed, it deforms and enters the receiving groove, thereby preventing the stopper 6 from hindering the butting work of the two arc-shaped seats 2; In some embodiments, the stopper 6 can also be set as a solid, and part of it is located in the receiving groove, and the remaining part is located at the end of the arc-shaped seat 2 to block the half compression column 3. When the stopper 6 is squeezed, the stopper 6 can slide into the receiving groove. In the natural state, the stopper 6 can be pushed by a spring piece or other elastic structures and partially exposed outside the arc-shaped seat 2.

[0025] Further, a plug board 7 is arranged on each arc-shaped seat 2, and the arc-shaped seat 2 can be slidably connected to the housing 1 through the plug board 7, and the plug board 7 and the housing 1 are connected by an elastic body 8; Among them, a support 9 for squeezing the outer wall of the half compression column 3 is arranged in each housing 1; In the present invention, after the two half compression columns 3 have wound the wire, the wire wound on the outer wall of the conductive sleeve 4 is not restricted by other means, that is, the wire may be in a loose state, which may cause unstable connection. To avoid this phenomenon, the support 9 can be used to squeeze the wire on the outer wall of the conductive sleeve 4, thereby further improving the connection effect and clamping effect; to protect the wire, a soft layer insulation structure such as a rubber layer can be laid on the extrusion surface of the support 9; Since the two half compression columns 3 need to perform operations such as docking, rotation, and being squeezed by the support 9, and the rotation operation cannot be synchronized with the extrusion operation, it is necessary to limit the movement process of the two half compression columns 3, that is, the two half compression columns 3 first dock and rotate first. At this time, the half compression column 3 and the support 9 are in a separated state. After the two half compression columns 3 have completed rotation, the half compression column 3 approaches the support 9 and uses the support 9 to squeeze the wire on the conductive sleeve 4. To achieve this operation mode, the insertion plate 7 and the elastic body 8 are needed. That is, in the natural state, due to the action of the elastic body 8, part of the half compression column 3 and the arc-shaped seat 2 is located outside the housing 1. The insertion plate 7 can guide the movement of the arc-shaped seat 2 and the half compression column 3. When the two half compression columns 3 are docked, the half compression column 3 is still partially located outside the housing 1. After the two half compression columns 3 have completed winding, the two housings 1 are mutually squeezed. At this time, the half compression column 3 squeezes the elastic body 8 by using the insertion plate 7, and the half compression column 3 synchronously slides on the housing 1 by using the insertion plate 7. The half compression column 3 and the support 9 approach each other, and the support 9 squeezes and fixes the wire on the conductive sleeve 4, thereby completing the line connection work.

[0026] Further, an arc-shaped strip 10 is provided in each housing 1, a plurality of locking holes 11 are formed in the arc-shaped strip 10, and a plurality of locking rods 12 that cooperate with the locking holes 11 are provided on the half compression column 3. When the half compression column 3 moves along its own axis, the locking rod 12 is inserted into or removed from the corresponding locking hole 11; When the support 9 contacts the guide on the conductive sleeve 4 and squeezes it, the line connection work is completed. At this time, the half compression column 3 only receives the frictional force of the support 9 in its own circumferential direction and is not restricted by other acting forces. Therefore, the half compression column 3 may rotate in the reverse direction and cause the wire to become loose. To lock the position of the half compression column 3, the above structural method can be used, that is, when the support 9 contacts the wire on the conductive sleeve 4, the half compression column 3 is pushed horizontally to move, so that the half compression column 3 drives the locking rod 12 to be inserted into the corresponding locking hole 11, thereby realizing the locking work of the position of the half compression column 3. At this time, the conductive sleeve 4 will move relative to the support 9; It should be noted that to prevent the locking rod 12 from automatically disengaging from the locking hole 11, elastic bosses can be provided on the inner wall of the locking hole 11 and the outer wall of the locking rod 12 to realize the self-locking work of the locking hole 11 and the locking rod 12.

[0027] Further, the two housings 1 are connected by a plurality of soft sheets 13, and the two housings 1 and the plurality of soft sheets 13 are integrally processed; Since the two housings 1 are connected by a number of flexible sheets 13, there is no need to worry about the two housings 1 separating and being unable to find the corresponding housings 1 for combined use, and this method is convenient for carrying; In actual use, the two housings 1 and a number of semi-pressure columns 3 can be integrally processed by injection molding, thus effectively simplifying the production method and improving the convenience of structural processing and use.

[0028] Furthermore, a number of long grooves are oppositely formed on one housing 1, and a number of inclined platforms 14 are arranged in the long grooves, and a number of hook strips 15 are arranged on the other housing 1 and are used in cooperation with the inclined platforms 14 in each long groove; By providing a number of long grooves and a number of hook strips 15 that cooperate with each other, the quick buckling and locking of the two housings 1 can be realized by the mutual clamping of the hook strips 15 and the inclined platforms 14, thereby improving the convenience of using the connector, and the arrangement of the number of inclined platforms 14 can provide different degrees of buckling tightness for the two housings 1.

[0029] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
