Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware, in particular to a wedge-shaped wire clamp. Background Art

[0002] The wedge clamp is used to connect a branch conductor to the main conductor. The patent with application number 201921572627.9 discloses a self-rotating anti-falling amp wedge clamp, including an amp wedge clamp body, a vertical surface is provided at one end of the C-shaped groove shell of the amp wedge clamp body, and one end of the vertical surface is connected to the C-shaped groove shell through a connecting part, and a hole is provided on the vertical surface, and a wedge block fixing member is provided in the hole. The wedge block fixing member fixes the wedge block, which can ensure reliable connection of the wire, good contact, good conductivity and connection mechanical strength. However, the C-shaped groove shell is generally made of aluminum. Although aluminum has excellent conductivity and is not easy to rust, its strength is low. Therefore, when the wedge block presses the wire into the C-shaped groove shell, the pressure on the wire cannot reach a large amount, because excessive pressure will cause the C-shaped groove shell to deform, thereby reducing the pressure. Therefore, the wire is not pressed very tightly. When the branch wire is subjected to a large tensile force, it may fall off the wire clamp. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a wedge-shaped wire clamp in view of the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a wedge-shaped wire clamp, including a wedge-shaped block and a C-shaped shell matched therewith, the two sides of the shell gradually shrink inward in the direction from the bottom surface to the top surface, and also including a C-shaped outer shell, the inner side shape of the outer shell matches the outer side shape of the outer shell, a tension block is arranged in the outer shell, and a threaded hole penetrating through the bottom surface of the tension block is arranged on one side of the wedge-shaped block, and a groove penetrating through the top surface of the wedge-shaped block is arranged, and the bottom plate is formed below the groove, and a through hole is arranged on the bottom plate, and a bolt can pass through the through hole and connect with the threaded hole so as to pull the wedge block into the shell and press the wire between the two.

[0005] Preferably, the shell is made of stainless steel or galvanized steel.

[0006] Preferably, the wedge block is made of stainless steel or galvanized steel.

[0007] Compared with the prior art, the utility model has the following advantages: the outer jacket can be put on the outside of the outer shell, and a tension block with a threaded hole is arranged inside the outer jacket, and a groove for accommodating the tension block is arranged on the wedge block. The wedge block can be pulled into the outer shell and the wire between the two can be pressed by connecting the bolts through the through holes on the bottom plate and the threaded holes. The outer jacket can strengthen and restrain the outer shell, so that the outer shell can withstand greater force without deformation, so the wire can be pressed tighter.

[0011] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0012] Specific implementation method: Combination Figure 1-2 As shown, a wedge-shaped wire clamp includes a wedge-shaped block 3 and a C-shaped shell 1 matched therewith. The wedge-shaped block 3 is made of stainless steel or galvanized steel and has high strength. The shell 1 is made of aluminum and has excellent conductivity. The two sides of the shell 1 gradually shrink inward from the bottom to the top. The upper and lower parts and the front side of the shell 1 are open. The wedge-shaped wire clamp also includes a C-shaped jacket 2. The upper and lower parts and the rear side of the jacket 2 are open. The inner shape of the jacket 2 matches the outer shape of the shell 1, so that the jacket 2 can be sleeved on the outer side of the shell 1. The outer shell 1 is strengthened and bounded by the outer shell 2. A tension block 21 is arranged in the outer shell 2. A threaded hole 211 is arranged on the tension block 21 and passes through its bottom surface. A groove 31 is arranged on one side of the wedge block 3 and passes through its top surface to accommodate the tension block 21. A bottom plate 32 is formed below the groove 31 of the wedge block 3 and a through hole is arranged on the bottom plate 32. The bolt 4 can pass through the through hole and connect with the threaded hole 211 so as to pull the wedge block 3 into the outer shell 1 and compress the wire between the two.

[0013] Preferably, the shell 1 is made of stainless steel or galvanized steel, which has high strength and is not prone to rust.

[0014] When not in use, the housing 1, the jacket 2 and the wedge block 3 are separated. When in use, the housing 1 is first hung on the main conductor. Generally, the main conductor is nearly horizontal (and both ends of the main conductor are fixed by electric poles, etc.). Then, the housing 1 is in the state of Figure 1 Rotate 90 degrees, the main conductor is located in the semicircular groove on the upper side of the housing 1, then hold the outer jacket 2 to allow the main conductor to enter the interior from the rear opening, then put the outer jacket 2 on the outside of the housing 1, then insert one end of the branch conductor into the semicircular groove on the lower side of the housing 1, then insert the wedge block 3 into the housing 1 so that the main conductor and the branch conductor are respectively located in the small circular grooves on both sides, then pass the bolt 4 through the through hole on the bottom plate 32 and connect it with the threaded hole 211, then tighten the bolt 4 to compress the conductor. Due to the existence of the outer jacket 2, the housing 1 can withstand greater force without deformation, so the conductor can be pressed tighter.

[0015] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
