Description

Technical Field

[0001] The present invention relates to the technical field of wire clamps, and in particular to a wire clamp and an operating method thereof. Background Art

[0002] Parallel groove wire clamps are a type of electrical hardware used to connect and fix conductors in power systems. They are mainly used to connect aluminum stranded wires or steel-core aluminum stranded wires with small and medium cross-sections and steel stranded wires of overhead lightning arresters at locations that do not bear tension. They are also used for jumper connections on non-straight pole towers and are widely used in power line projects.

[0003] Parallel groove wire clamps are often used at the T-junction of wires or the connection of bows, but in actual work, the two connected wires often have different wire diameters. The large difference in wire diameters will cause the wire on the side with the smaller wire diameter to be unable to be tightened. If the adjustment is too large, it will cause damage to the wire with the larger wire diameter on the other side. In the prior art, bolts are usually used to directly crimp the wires, which will cause wire breakage or poor contact. During long-term use, due to thermal expansion and contraction or mechanical creep, the preload force will be lost, affecting the stability of the connection.

[0004] Therefore, in order to solve the above technical problems, reduce line failure problems caused by the inability to adapt to different wire diameters, and maintain stable connection pressure and contact resistance, we propose a wire clamp and an operating method. Summary of the invention

[0005] In view of the above problems, a wire clamp in the present invention is proposed.

[0011] As a preferred solution of the wire clamp of the present invention, the arc-shaped pressure plate has a first surface and a second surface opposite to each other, the second surface contacts the cable in the surface area, and a cone is provided at the end of the fastening bolt.

[0012] As a preferred solution of the wire clamp of the present invention, the cone applies force to the first surface in a point area by rotating the fastening bolt.

[0013] As a preferred solution of the wire clamp of the present invention, wherein: a limiting bolt is connected to the first surface, and the limiting bolt is movably matched with the through hole, and the inner wall of the first wire groove is provided with anti-slip grooves.

[0014] One of the beneficial effects of the present invention is that the cable is clamped into the first wire groove, and then the first clamp and the second clamp are combined, and the arc pressure plate is moved by rotating the fastening bolts according to different wire diameters, so that the arc pressure plate tightens the cable, and the arc pressure plate is used to increase the contact area of ​​the connection, reduce contact resistance, improve poor contact and wire breakage, and concentrate force on the point area of ​​the arc clamp through the cone to ensure the tightness of the connection, and the arc pressure plate can evenly disperse the stress through the surface area, which helps to maintain the preload and reduce the loss of preload in a dynamic environment.

[0015] In view of the above problems, an operating method of a wire clamp in the present invention is proposed.

[0016] To solve the above technical problems, the present invention provides the following technical solutions: a method for operating a wire clamp, comprising: a wire clamp; and inserting the cable into the first wire groove, and then slidingly engaging with the positioning block through the positioning groove, thereby assembling the first clamping plate and the second clamping plate.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Example 1

[0031] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, provides a wire clamp, which can effectively and evenly disperse stress and protect cables from damage during use by setting an arc-shaped pressure plate 203a.

[0032] Specifically, the first connecting component 100 includes a mounting component 101 and a locking component 102 arranged on the outer wall of the mounting component 101; and, the second connecting component 200 includes a fixing component 201, a movable component 202 movably cooperated with the locking component 102, and a reinforcing component 203 movably arranged on the outer wall of the fixing component 201; and, the reinforcing component 203 includes an arc-shaped pressure plate 203a, and by applying force to one side of the arc-shaped pressure plate 203a, the other side of the arc-shaped pressure plate 203a is used to tighten the cable.

[0033] Among them, the cooperation between the locking member 102 and the movable member 202 can prevent the fixing member 201 from slipping after being connected to the mounting member 101; the size of the wire clamp is preferably set to a total length * width * height of 150mm * 70mm * 40mm, and the pressing plate is preferably set to a length of 150mm, a width of 18mm, and a thickness of 5mm; through the design of the arc-shaped pressure plate 203a, the problem of connecting and overlapping the main and secondary lines of different sizes can be solved. The arc-shaped pressure plate 203a can not only adapt to cables of different wire diameters within a certain range, but also compared with the prior art of directly crimping with flat-head bolts, the arc-shaped pressure plate 203a increases the contact area and improves poor contact and wire breakage.

[0034] In summary, by setting up the arc pressure plate 203a, force is applied from one side of the arc pressure plate 203a, and the cable is compressed on the other side of the arc pressure plate 203a, thereby increasing the scope of application. By transmitting pressure through the arc pressure plate 203a, the pressure on the cable can be more evenly distributed, avoiding damage or deformation of the cable caused by excessive direct pressure.

[0035] Example 2

[0036] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention, is based on the previous embodiment, except that by rotating the fastening bolt 201a-31, the arc-shaped pressure plate 203a can be pushed to fit the cable from one side and apply force to it to complete the fastening. Through this setting, looseness can be avoided and the use time can be extended.

[0037] Specifically, the mounting member 101 includes a first clamping plate 101 a , on which a first wire groove 101 b is formed, and the positioning member 102 includes a sliding groove 102 a formed on the first clamping plate 101 a .

[0038] Preferably, a positioning block 102b is provided on the side wall of the slide groove 102a, and a slope 102b-1 is provided on the positioning block 102b, and the slope 102b-1 extends from the connection between the slide groove 102a and the positioning block 102b to the center of the first wire groove 101b.

[0039] The first wire trough 101b is used to fit the upper surface of the cable during initial installation, and then the arc-shaped pressing plate 203a is used to press the cable from the lower surface, thereby fastening the cable from both sides. There are two first wire troughs 101b, so that two cables of different sizes can be fixed.

[0040] Preferably, the fixing member 201 includes a second clamping plate 201a movably engaged with the first clamping plate 101a, and a second wire groove 201a-1 is provided on the second clamping plate 201a. The movable member 202 includes a slide plate 202a provided on the second clamping plate 201a, and the slide plate 202a is movably engaged with the slide groove 102a, and the outer wall of the second clamping plate 201a is provided with a positioning groove 202a-1 which is engaged with the positioning block 102b.

[0041] The positioning blocks 102b are preferably arranged on both sides of each slide groove 102a. The positioning blocks 102b cooperate with the positioning groove 202a-1 to prevent the second clamping plate 201a from falling.

[0042] Preferably, three threaded holes 201a - 3 are arranged in an array on the outer wall of the second clamping plate 201a , and a through hole 201a - 2 is provided between two adjacent threaded holes 201a - 3 , and a fastening bolt 201a - 31 is provided in cooperation with the inner threads of the threaded holes 201a - 3 .

[0043] Preferably, the arc-shaped pressing plate 203a has a first surface 203a-1 and a second surface 203a-2 opposite to each other, the second surface 203a-2 contacts the cable in the surface area Q, and a cone 201a-32 is provided at the end of the fastening bolt 201a-31.

[0044] Preferably, the cone 201a-32 applies force to the first surface 203a-1 at the point area P by rotating the fastening bolt 201a-31.

[0045] Among them, the curvature of the arc pressure plate 203a is relatively small, so that it can adapt to cables of different wire diameters within a certain range, and when the arc pressure plate 203a presses the cable, the contact area between the two is the surface area Q; when the cone 201a-32 applies force to the arc pressure plate 203a, since the arc pressure plate 203a needs to fit the curvature of the cable and is designed to be an arc, compared with directly using flat-head bolts to tighten the arc pressure plate 203a, the contact area is increased, resulting in force loss, and it is easy to cause the risk of breaking the arc pressure plate 203a.

[0046] Therefore, the contact area between the cone 201a-32 and the arc pressure plate 203a is set as the point area P. The force can be concentrated through the point contact of a small area. According to the pressure formula, the smaller the contact area, the greater the pressure. The concentrated pressure helps to provide a larger preload force in the initial stage of connection, ensuring the tightness and stability of the connection. The design of the cone 201a-32 can reduce the preload force loss caused by the embedded contact surface and material creep.

[0047] Moreover, the cone 201a-32 with a small contact surface can make the clamping action faster and more accurate, thereby improving the connection efficiency. When tightening the bolt, most of the torque is used to overcome friction. By reducing the contact area, friction loss can be reduced, allowing more torque to be used for clamping force, thereby improving the connection efficiency.

[0048] Therefore, by setting up an arc-shaped pressure plate 203a, one side receives force from multiple point areas P, and then transmits it to the cable through the surface area Q from the other side. The arc-shaped pressure plate 203a can better adapt to the shape of the cable through surface-to-surface contact, provide a larger contact area, thereby reducing contact resistance, and improving connection reliability and conductivity; and face-to-face contact helps to distribute stress more evenly, reduce material deformation caused by long-term loading, thereby maintaining a more stable pre-tightening force. By tightening the cable in this way, the overall connection stability can be improved, the loose connection due to external force can be reduced, and it is more convenient for long-term and effective use.

[0049] Preferably, a limiting bolt 203b is connected to the first surface 203a-1, and the limiting bolt 203b is movably matched with the through hole 201a-2, and the inner wall of the first wire groove 101b is provided with an anti-slip pattern 101b-1.

[0050] Among them, two limiting bolts 203b are preferably provided, the nut on the limiting bolt 203b is larger than the diameter of the through hole 201a-2, and the limiting bolt 203b is fixedly connected to the first surface 203a-1. When the fastening bolt 201a-31 is rotated, it will approach and then push the arc pressure plate 203a. The limiting bolt 203b and the through hole 201a-2 are movably cooperated to limit the moving direction of the arc pressure plate 203a, thereby pushing the arc pressure plate 203a to make it close to the cable, and the other side of the cable is against the anti-slip pattern 101b-1, which can complete the fastening and fixation of the cable.

[0051] In summary, by setting the fastening bolt 201a-31, after the cable is placed in the first wire groove 101b, the fastening bolt 201a-31 is rotated, and the tip of the cone 201a-32 will approach and push the arc pressure plate 203a, thereby cooperating with the anti-slip pattern 101b-1 on the other side, so that the cable can be fastened and installed, and the operation is simple and convenient.

[0052] Example 3

[0053] Reference Figure 1 to Figure 6 , which is the third embodiment of the present invention, and this embodiment provides an operating method for a wire clamp, wherein the cable is clamped into the first wire groove 101b, and then the first clamping plate 101a and the second clamping plate 201a are assembled by slidingly engaging with the positioning block 102b through the positioning groove 202a-1.

[0054] Preferably, after the second clamping plate 201a and the first clamping plate 101a are assembled, the cone 201a-31 is moved close to the arc-shaped pressing plate 203a by rotating the fastening bolt 201a-31, and force is applied to the arc-shaped pressing plate 203a, so that the second surface 203a-2 on the arc-shaped pressing plate 203a contacts the cable and is fastened.

[0055] In summary, by rotating the fastening bolts 201a-31, the arc-shaped pressing plate 203a is moved and fitted onto the cable to prevent the cable from moving, thereby completing the fastening. This setting can adapt to the installation of cables of different sizes within a certain range.
