Description

Technical Field

[0001] The utility model belongs to the technical field of high-voltage transmission lines, and in particular relates to a high-voltage transmission line conductor tension connector. Background Art

[0002] During the construction of high-voltage overhead transmission lines, due to the long transmission distances, multiple shafts of conductors must be connected. Transmission line cutting, modification, and maintenance also require conductor connection. Traditional conductor connection methods often rely on large tools such as hydraulic presses for crimping. This method is not only complex and inefficient, but also prone to damage to the conductors, affecting their electrical conductivity and mechanical strength. Furthermore, the hydraulic crimping process carries certain safety risks. Improper operation can result in equipment damage or personal injury. Utility Model Content

[0003] The purpose of the utility model is to provide a high-voltage transmission line conductor tension connector to address the above-mentioned technical problems, thereby achieving a fast and stable connection of the conductors and reducing the operating risks of the staff.

[0004] In view of this, the utility model provides a high-voltage transmission line conductor tension connector, comprising: a sleeve, which is sleeved on the conductor, and is characterized in that the outer end and the inner end of the sleeve are respectively provided with a limit guide component, and the two limit guide components are used to guide the core wire of the conductor into the sleeve, and limit the front and rear ends of the core wire. A clamping limit mechanism is also provided between the two limit guide components, and the clamping limit mechanism is used to clamp and limit the middle end of the core wire.

[0005] In this technical solution, before connecting the wires, the outer conductive layer at the wire connection is first stripped off to expose the core wire, and then the core wire is inserted into the sleeve. The two limiting guide components accurately guide the core wire to the center position of the sleeve, and first limit the left and right ends of the core wire, and then the clamping limit mechanism reliably clamps and limits the middle end of the core wire. Under the action of the limiting guide component and the clamping limit mechanism, the stability of the wire connection and the construction efficiency are improved, while the safety risks of the staff are reduced.

[0006] In the above technical solution, further, the limiting guide assembly includes: a limiting ring, and limiting bars are provided on the left and right sides of the limiting ring, and the limiting bars are used to limit the wire core guide.

[0007] In the above technical solution, further, a number of the limit bars are equidistantly arranged in the circumferential direction, and the limit bars are arranged obliquely, and the outer walls of the left and right ends of the wire core are wrapped between the limit bars.

[0008] In this technical solution, when the core wire of the conductor is inserted into the sleeve, it first contacts the limiting guide assembly. Because the limiting strips are arranged at an angle, the core wire can be effectively guided to the center of the sleeve during insertion. After the core wire is inserted, its left and right outer walls are wrapped by the limiting strips distributed evenly around the circumference, achieving initial positioning of the left and right ends of the core wire, thereby ensuring the core wire's position stability before subsequent operations.

[0009] In the above technical solution, further, the limiting strip is made of elastic plastic material.

[0010] In this technical solution, when the core wire passes through the limiting ring, the limiting strip will undergo elastic deformation, thereby clamping and fixing the core wire.

[0011] In the above technical solution, further, the clamping and limiting mechanism includes:

[0012] a first clamping block, the first clamping block being fixedly arranged on the inner bottom of the sleeve;

[0013] The second clamping block is correspondingly opened above the first clamping block, the upper end of the second clamping block is provided with a bearing, the other end of the bearing is connected to a threaded rod, the threaded rod passes through the sleeve and is threadedly connected to the sleeve.

[0014] In the above technical solution, further, a knob is fixedly connected to the top end of the threaded rod.

[0015] In this technical solution, after the core wire is inserted into the bottom of the sleeve, the left and right ends of the core wire are clamped and fixed by the limit bars, and under the action of the limit bars, the middle part of the core wire is on the inner wall of the first clamping block. Then the staff rotates the knob to rotate the threaded rod, thereby driving the second clamping block to clamp the outer wall of the core wire. Under the cooperation of the first clamping block and the second clamping block, the outer wall of the middle end of the core wire is limited and clamped.

[0016] In the above technical solution, further, the inner walls of the first clamping block and the second clamping block are fixedly connected with rubber pads. Due to the high friction coefficient of the rubber pads, they can significantly improve the grip of the clamping block on the wire.

[0017] In the above technical solution, further, a guide plate is provided at one end of the sleeve away from the conductor, and the guide plate is used to connect a jumper wire at the pole tower end.

[0018] The beneficial effects of the utility model are:

[0019] 1. When the core wire of the conductor is inserted into the sleeve, it first contacts the limit guide assembly. Since the limit strip is set at an angle, the core wire can be effectively guided to the center position of the sleeve during the insertion process. As the core wire is inserted, its left and right outer walls are wrapped by the limit strips evenly distributed circumferentially, achieving preliminary limitation on the left and right ends of the core wire, thereby ensuring the position stability of the core wire before subsequent operations.

[0020] 2. After the core wire is inserted into the bottom of the sleeve, the left and right ends of the core wire are clamped and fixed by the limit bars, and under the action of the limit bars, the middle part of the core wire is on the inner wall of the first clamping block. Then the staff rotates the knob to rotate the threaded rod, thereby driving the second clamping block to clamp the outer wall of the core wire. Under the cooperation of the first clamping block and the second clamping block, the outer wall of the middle end of the core wire is limited and clamped. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Depend on Figure 1-3 As shown, this embodiment provides a high-voltage transmission line conductor tension connector including: a sleeve, the sleeve is sleeved on the conductor, the outer end and the inner end of the sleeve are respectively provided with a limiting guide assembly, the two limiting guide assemblies are used to guide the core wire of the conductor into the sleeve, and limit the front and rear ends of the core wire, and a clamping limiting mechanism is also provided between the two limiting guide assemblies, and the clamping limiting mechanism is used to clamp and limit the middle end of the core wire. Before the conductors are connected, the outer conductive layer of the conductor connection is first stripped off to expose the core wire, and then the core wire is inserted into the sleeve, the two limiting guide assemblies accurately guide the core wire to the center position of the sleeve, and first limit the left and right ends of the core wire, and then the clamping limiting mechanism reliably clamps and limits the middle end of the core wire. Under the action of the limiting guide assembly and the clamping limiting mechanism, the stability of the conductor connection and the construction efficiency are improved, while the safety risk of the staff is reduced.

[0033] Furthermore, the limiting guide assembly includes: a limiting ring, and limiting strips are provided on the left and right sides of the limiting ring, and the limiting strips are used to guide and limit the wire core. A number of limiting strips are circumferentially equidistant, and a number of the limiting strips are inclined, and the outer walls of the left and right ends of the wire core are wrapped between the number of limiting strips. When the core wire of the conductor is inserted into the sleeve, the first thing it contacts is the limiting guide assembly. Since the limiting strips are inclined, the core wire can be effectively guided to the center position of the sleeve during the insertion process. After the insertion of the core wire is completed, the outer walls of the left and right ends are wrapped by the limiting strips circumferentially equidistantly distributed, so as to achieve preliminary limiting of the left and right ends of the core wire, thereby ensuring the position stability of the core wire before subsequent operations.

[0034] Furthermore, the limiting strip is made of elastic plastic material. When the core wire passes through the limiting ring, the limiting strip will elastically deform, thereby clamping and fixing the core wire.

[0035] Furthermore, the clamping and limiting mechanism includes: a first clamping block, which is fixedly arranged at the bottom of the sleeve; a second clamping block, which is correspondingly opened above the first clamping block, and a bearing is provided at the upper end of the second clamping block, and the other end of the bearing is connected to a threaded rod, which passes through the sleeve and is threadedly connected to the sleeve. The top of the threaded rod is fixedly connected to a knob. After the core wire is inserted into the bottom of the sleeve, the left and right ends of the core wire are clamped and fixed by the limiting strips, and under the action of the limiting strips, the middle part of the core wire is located on the inner wall of the first clamping block. Then the staff rotates the knob to rotate the threaded rod, thereby driving the second clamping block to clamp the outer wall of the core wire. Under the cooperation of the first clamping block and the second clamping block, the outer wall of the middle end of the core wire is limited and clamped.

[0036] Furthermore, the inner walls of the first clamping block and the second clamping block are fixedly connected with rubber pads. Due to the high friction coefficient of the rubber pads, they can significantly improve the grip of the clamping block on the wire.
