Description

Technical Field

[0001] The present invention relates to the technical field of connection structures, in particular to a connector for fixing angle steel tower lines. Background Art

[0002] Angle steel towers are core infrastructure in the fields of power transmission, communication base stations, and bridge support. Their structural stability and safety directly affect the reliability and service life of the entire project. In the construction of transmission lines, angle steel towers are widely used to erect high-voltage and ultra-high-voltage lines, and undertake the important task of supporting conductors, insulator strings, and hardware. The line connector on the angle steel tower is the main structure for connecting conductors. It can dock and fix two conductors to prevent the winding positions from detaching and disconnecting.

[0003] Commonly used connectors are mainly snap-on or squeeze-lock types. The snap-on connector clamps the two wires so that they cannot be loosened. When using this connector, workers still need to wrap the two wires together, which is less convenient to use. The squeeze-lock connector mainly clamps and fixes the exposed metal wires on the two wires to achieve line connection. However, this method can only achieve friction fixation of the metal wires, that is, the metal wires are prone to bifurcation, debonding, and loosening, and the connection is not firm. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a connector for fixing angle steel tower lines, and the specific technical solution adopted is:

[0006] Furthermore, there are several conductive sleeves on the semi-pressed column arranged along the length direction of the semi-pressed column.

[0007] Furthermore, a plurality of ribs are arranged on the conductive sleeve.

[0008] Furthermore, the positions of the corresponding ribs on the two half-compression columns are staggered.

[0009] Furthermore, a stopper for positioning the semi-compression column is protruded from both end surfaces of each of the arc-shaped seats, and the stopper can be flattened or squeezed into the inner side of the arc-shaped seat.

[0010] Furthermore, each of the arc-shaped seats is provided with an inserting plate, and the arc-shaped seat can be slidably connected to the shell through the inserting plate, and the inserting plate and the shell are connected by an elastic body;

[0011] Wherein, each of the shells is provided with a support body for compressing the outer wall of the semi-compression column.

[0012] Furthermore, each of the shells is provided with an arc-shaped bar, on which a number of lock holes are opened, and on the semi-compression column a number of lock rods for use with the lock holes are provided. When the semi-compression column moves along its own axial direction, the lock rods are inserted into or moved out of the corresponding lock holes.

[0013] Furthermore, the two shells are connected by a plurality of soft films, and the two shells and the plurality of soft films are processed into an integrated whole.

[0014] Furthermore, one of the shells is provided with a plurality of long slots, and a plurality of inclined platforms are arranged in the long slots, and the other shell is provided with a plurality of hooks for use with the inclined platforms in the long slots.

For example, they can refer to fixed connections, detachable connections, or integrated connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0028] like Figures 1 to 5 As shown, a connector for fixing angle steel tower lines of the present invention comprises two housings 1 that can be interlocked and a semi-pressing column 3 provided on each housing 1. Both ends of the semi-pressing column 3 extend to the outside of the housing 1, and the semi-pressing column 3 can rotate on the housing 1 through two arc-shaped seats 2. A conductive sleeve 4 is provided on each semi-pressing column 3.

[0029] In the present invention, a shell 1 and a half-pressure column 3 are used together to form a group. The straight line where the half-pressure column 3 is located is parallel to the surface where the shell 1 is located. The two side walls at opposite positions on the shell 1 are inlaid with arc seats 2. The half-pressure column 3 is rotatably arranged in the two arc seats 2. The two half-pressure columns 3 can also dock with each other when the two shells 1 are closed to each other. In this way, the two half-pressure columns 3 can form a complete cylindrical shape, and the two arc seats 2 at corresponding positions can dock to form a ring, so that the column can rotate within 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 docked, the conductive sleeves 4 on the two half-pressure columns 3 can clamp the guide between them;

[0030] When in use, place the two peeled wire ends at the position of the conductive sleeve 4 on a half-pressing column 3. The two wires can be inserted between the two shells 1 in the same direction, or inserted between the two shells 1 opposite to each other. When the wires are placed, close the two shells 1. At this time, the two half-pressing columns 3 are synchronously docked, and the two opposite conductive sleeves 4 on the two half-pressing columns 3 clamp and fix the wire ends therebetween. Then, rotate the two half-pressing columns 3 to wrap the wires around the column composed of the two half-pressing columns 3, that is, wrap more exposed parts of the wires around the conductive sleeve 4, thereby realizing the connection of the lines.

[0031] By connecting the wires by clamping first and then winding, the wire connection strength can be effectively improved, the connection method can be simplified, the tedious operation of manually winding the wires can be avoided, the convenience of the structure can be improved, and the bifurcation, debonding and loosening of the wire ends can be avoided.

[0032] It should be pointed out that, since the wires need to be pressed and wound on the conductive sleeve 4, the two wires can achieve a conductive connection effect through the conductive sleeve 4 without having to connect the two wires directly, which facilitates the connection and avoids the tedious operation of accurately docking the two wire heads; since the conductive sleeves 4 on the two half-pressure columns 3 need to clamp the wire heads, the wire heads will occupy part of the space between the two conductive sleeves 4; in order to facilitate the insertion of the wires into the shell 1, a wire hole can be opened on the shell 1.

[0033] Furthermore, the conductive sleeves 4 on the semi-pressurized column 3 are arranged in a plurality of directions along the length of the semi-pressurized column 3;

[0034] In order to achieve the connection of multiple wires, the multiple wires can be divided into several groups, and each group is provided with two wires that need to be connected. In this way, the two wires in each group can be connected with the help of a conductive sleeve 4 on the half-pressure column 3. The multiple conductive sleeves 4 on the two half-pressure columns 3 can achieve the connection of multiple groups of wires, thereby reducing the number of connectors used, reducing wiring complexity, improving space utilization, and completing multi-line connection in a single operation, saving installation time.

[0035] Furthermore, a plurality of ribs 5 are arranged on the conductive sleeve 4;

[0036] By providing a plurality of ribs 5 on the conductive sleeve 4, the ribs 5 can be used to enhance the friction effect between the conductive sleeve 4 and the conductor head, thereby improving the clamping effect; the arrangement direction of the plurality of ribs 5 needs to be parallel to the length direction of the conductor, and the length direction of the ribs 5 needs to be perpendicular to the length direction of the conductor;

[0037] It should be pointed out that the cross-sectional shape of the rib 5 can be any shape, such as arc, square, etc. On the premise of avoiding squeezing of the wire head, ribs 5 of any shape that help to improve the clamping effect are within the protection scope of this case.

[0038] Furthermore, in order to improve the clamping effect of the conductive sleeve 4 on the conductor head, the positions of the corresponding ribs 5 on the two half-pressing columns 3 are staggered. In this way, when the two half-pressing columns 3 are docked, the corresponding ribs 5 on the two conductive sleeves 4 can be staggered and docked, thereby pressing the conductor head into a continuous curved shape;

[0039] In some embodiments, a rib 5 on one of the two conductive sleeves 4 can be used in conjunction with a rib 5 on the other conductive sleeve 4, that is, there are multiple docking areas of the ribs 5 between the two conductive sleeves 4, so that the two conductive sleeves 4 can achieve multi-point clamping of the wire heads. The rib 5 on one conductive sleeve 4 can also be used in conjunction with two adjacent ribs 5 on the other conductive sleeve 4, that is, one rib 5 can have two clamping points.

[0040] Furthermore, a stopper 6 for positioning the semi-pressing column 3 is protruded from both end surfaces of each arc-shaped seat 2, and the stopper 6 can be flattened or squeezed into the inner side of the arc-shaped seat 2;

[0041] Since the two half-pressure columns 3 need to be butted together, the corresponding two arc-shaped seats 2 also need to be butted together. Therefore, without setting other structures, the half-pressure column 3 can directly detach from the arc-shaped seat 2, which causes the structure to be scattered. To avoid this phenomenon, a blocking body 6 can be set at both ends of the arc-shaped seat 2 to block the half-pressure column 3, so that the half-pressure column 3 is kept in the arc-shaped seat 2; the blocking method of the blocking body 6 can be to directly block the plane of the half-pressure column 3, or the arc of the overall shape composed of the arc-shaped seat 2 and the two blocking bodies 6 can be greater than the semicircle, thereby allowing the half-pressure column 3 to rotate, but it will be restricted in the arc-shaped seat 2;

[0042] When the two half-pressure columns 3 are docked, the corresponding two arc-shaped seats 2 are docked synchronously, and the blocking bodies 6 on the two arc-shaped seats 2 will be squeezed. The blocking bodies 6 can be deformed and flattened, thereby ensuring that the two arc-shaped seats 2 are docked smoothly. Of course, a receiving groove can also be opened at the end of the arc-shaped seat 2, and the blocking body 6 can be set on the receiving groove. When the blocking body 6 is squeezed, it deforms and enters the receiving groove, thereby avoiding the blocking body 6 from hindering the docking work of the two arc-shaped seats 2;

[0043] In some embodiments, the blocker 6 can also be set to be solid, with part of it located in the receiving groove, and the remaining part located at the end of the arc seat 2 and blocking the semi-compression column 3. When the blocker 6 is squeezed, the blocker 6 can slide into the receiving groove. In the natural state, the blocker 6 can use the spring sheet and other elastic structures to push and partially appear outside the arc seat 2.

[0044] Furthermore, each arc seat 2 is provided with an insert plate 7, and the arc seat 2 can be slidably connected to the housing 1 through the insert plate 7, and the insert plate 7 and the housing 1 are connected through an elastic body 8;

[0045] Each shell 1 is provided with a support 9 for squeezing the outer wall of the semi-compression column 3;

[0046] In the present invention, after the two halves of the pressure column 3 are wound around the conductor, the conductor wound on the outer wall of the conductive sleeve 4 is not subject to other constraints, that is, the conductor may be in a loose state, which will cause an unstable connection. To avoid this phenomenon, the support body 9 can be used to squeeze the conductor on the outer wall of the conductive sleeve 4, thereby further improving the connection effect and the clamping effect; to protect the conductor, the extrusion surface of the support body 9 can be paved with a soft insulating structure such as a rubber layer;

[0047] Since the two half-pressing columns 3 need to be docked, rotated, and squeezed by the support body 9, and the rotation operation cannot be performed synchronously with the squeezing operation, it is necessary to limit the movement process of the two half-pressing columns 3, that is, the two half-pressing columns 3 are first docked and rotated, at this time the half-pressing columns 3 and the support body 9 are in a separated state, and when the two half-pressing columns 3 have completed their rotation, the half-pressing columns 3 are close to the support body 9 and use the support body 9 to squeeze the wire on the conductive sleeve 4. In order to realize this operation mode, it is necessary to use the plug plate 7 and the elastic body 8, that is, in the natural state, due to the elastic body 8 Due to the effect of the half-pressure column 3 and the arc seat 2, parts of the half-pressure column 3 and the arc seat 2 will be located outside the shell 1, and the plug plate 7 can guide the movement of the arc seat 2 and the half-pressure column 3. When the two half-pressure columns 3 are docked, the half-pressure column 3 is still in a state of being partially located outside the shell 1. When the two half-pressure columns 3 are wound, the two shells 1 are squeezed against each other. At this time, the half-pressure column 3 uses the plug plate 7 to squeeze the elastomer 8, and the half-pressure column 3 synchronously slides on the shell 1 using the plug plate 7. The half-pressure column 3 and the bracket 9 approach each other, and the bracket 9 squeezes and fixes the wire on the conductive sleeve 4, thereby completing the line connection work.

[0048] Furthermore, each housing 1 is provided with an arc-shaped bar 10, on which a plurality of lock holes 11 are opened, and a plurality of lock rods 12 for use with the lock holes 11 are provided on the semi-compression column 3. When the semi-compression column 3 moves along its own axial direction, the lock rods 12 are inserted into or removed from the corresponding lock holes 11;

[0049] When the support body 9 contacts the guide on the conductive sleeve 4 and squeezes it, the line connection work is completed. At this time, the half-pressing column 3 is only subjected to the friction force of the support body 9 in its own circumferential direction, and is not restricted by other forces. Therefore, the half-pressing column 3 may rotate in the opposite direction and cause the wire to loosen. In order to lock the position of the half-pressing column 3, the above-mentioned structural method can be used, that is, when the support body 9 contacts the wire on the conductive sleeve 4, the half-pressing column 3 is pushed to move laterally, so that the half-pressing column 3 drives the locking rod 12 to insert into the corresponding lock hole 11, thereby realizing the locking work of the position of the half-pressing column 3. At this time, the conductive sleeve 4 will move relative to the support body 9;

[0050] It should be noted that, in order to prevent the locking rod 12 from automatically escaping from the locking hole 11 , elastic bosses may be provided on both the inner wall of the locking hole 11 and the outer wall of the locking rod 12 to achieve self-locking of the locking hole 11 and the locking rod 12 .

[0051] Furthermore, the two shells 1 are connected by a plurality of soft films 13, and the two shells 1 and the plurality of soft films 13 are integrally processed;

[0052] Since the two shells 1 are connected by a plurality of soft sheets 13, there is no need to worry about the two shells 1 being separated and unable to find the corresponding shell 1 and use them together, and this method is convenient for carrying;

[0053] In actual use, the two shells 1 and the plurality of semi-compression columns 3 can be processed as an integral whole by injection molding, thereby effectively simplifying the production method and improving the convenience of structural processing and use.

[0054] Furthermore, a plurality of long slots are formed on one housing 1, and a plurality of inclined platforms 14 are arranged in the long slots, and a plurality of hooks 15 are provided on the other housing 1 for use with the inclined platforms 14 in the long slots.

[0055] By setting up a number of long grooves and a number of hook strips 15 that cooperate with each other, the two shells 1 can be quickly snapped together and locked by utilizing the mutual snap connection between the hook strips 15 and the ramps 14, thereby improving the convenience of using the connector, and the setting of a number of ramps 14 can provide different degrees of snap-fit tightness for the two shells 1.

[0056] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
