[0039] The present invention provides a low-voltage "T" contact multifunctional wire clamp 100.

[0040] See also Figure 1-Figure 9 In one embodiment of the present invention, the low-voltage "T" contact multifunctional wire clamp 100 includes a base 10, a pressure block structure 20 and a fixing structure 30. The base 10 is arranged on a lower housing 40 and is provided with at least one accommodating groove 11; the pressure block structure 20 includes a first pressure block 21 and a second pressure block 22. One side of the first pressure block 21 is sleeved on the second pressure block 22. Both are installed in the accommodating groove 11 to form a clamping space with the side wall of the accommodating groove 11. The first pressure block 21 is provided with a first notch 211a, and the second pressure block 22 is provided with a second notch 221a. The first pressure block 21 and the second pressure block 22 are provided with a first notch 221a. When the first pressing block 21 and the second pressing block 22 are connected, the first notch 211a and the second notch 221a are staggered to form an axial hole; the fixing structure 30 includes a first fixing member 31 and a second fixing member 32, the base 10 is provided with a square hole 12, the square hole 12 and the axial hole staggered by the first notch 211a and the second notch 221a are located on an axis, the first fixing member 31 passes through the square hole 12 and the axial hole and is partially exposed on the upper surface of the first pressing block 21 and the second pressing block 22, the second fixing member 32 is located on the first pressing block 21 and the second pressing block 22 and is connected to the second fixing member 32;

[0041] When the second fixing piece 32 is tightened, the first pressing block 21 and the second pressing block 22 are opened outward, reducing the distance with the inner wall of the accommodating groove 11, and reducing the clamping space formed with the side wall of the accommodating groove 11 for clamping the wire 60; when the second fixing piece 32 is loosened, the first pressing block 21 and the second pressing block 22 can be retracted inward, and when retracted, the clamping force of the first pressing block 21 and the second pressing block 22 on the wire 60 is gradually reduced, so that the wire 60 can be pulled out of the wire clamp.

[0042] In this embodiment, there are two receiving grooves 11, which are spaced apart and not connected, and are located on the same horizontal plane. Both sides of the receiving groove 11 are bent upwards to form a "C" shape as a whole.

[0043] The first pressing block 21 and the second pressing block 22 are connected in the accommodating groove 11 on the left side, wherein the pressing block structure 20 also includes a third pressing block 23 and a fourth pressing block 24, the third pressing block 23 is provided with a third notch 231a, and the fourth pressing block 24 is provided with a fourth notch 241a. When the third pressing block 231a and the fourth pressing block 241a are connected, the third notch 231a and the fourth notch 241a are also staggered to form an axial hole like the first notch 211a and the second notch 221a.

[0044] The third pressing block 23 and the fourth pressing block 24 are connected in the receiving groove 11 on the right side, and multiple branch wires can be clamped. It should be noted that this embodiment is only demonstrated by taking two receiving grooves 11 as an example. If multiple wires 60 need to be clamped, more receiving grooves 11 can be provided to put a corresponding number of pressing block structures 20.

[0045] In one embodiment of the present invention, the first pressing block 21 includes a first extrusion portion 211 and a first connecting portion 212, the first extrusion portion 211 faces the inner wall of the accommodating groove 11, and the first notch 211a is provided on the first connecting portion 212; the second pressing block 22 includes a second extrusion portion 221 and a second connecting portion 222, the second extrusion portion 221 faces the inner wall of the accommodating groove 11, and the second connecting portion 222 is inserted into the first connecting portion 212 and connected to the first pressing block 21.

[0046] The third pressing block 23 includes a third extruding portion 231 and a third connecting portion 232, wherein the third extruding portion 231 faces the inner wall of the accommodating groove 11, and the third notch 231a is provided on the third connecting portion 232. The fourth pressing block 24 includes a fourth extruding portion 241 and a fourth connecting portion 242, wherein the fourth extruding portion 241 faces the inner wall of the accommodating groove 11, and the fourth connecting portion 242 is inserted into the third connecting portion 232 and connected to the third pressing block 23.

[0047] In this embodiment, the first extrusion portion 211 and the second extrusion portion 221 are both in an arc shape, and cooperate with the bent side wall of the receiving groove 11 to form a ring-shaped clamping space, which is convenient for clamping the wire 60. The first connection portion 212 is also in an arc shape, and the second connection portion 222 is cylindrical. It should be noted that the arc length of the first connection portion 212 exceeds half of the complete ring, which can wrap the second connection portion 222 and prevent the second connection portion 222 from detaching from the side of the first connection portion 212, so as to avoid the first pressing block 21 and the second pressing block 23 from detaching.

[0048] Similarly, the connection method between the third connecting part 232 and the fourth connecting part 242 is the same as the connection method between the first connecting part 212 and the second connecting part 222; the difference is that the third extrusion part 231 is a solid cylinder, and of course it can also be an arc shape, and the fourth extrusion part 241 is in the shape of a pliers, which is used to clamp the wire 60 with a smaller diameter. It can be understood that according to the requirements of use, the pressing block can be designed with multiple specifications and multiple different extrusion surfaces to be compatible with the clamping of wires 60 of different specifications, thereby improving the adaptability of the device.

[0049] In one embodiment of the present invention, a boss 33 is disposed on the first fixing member 31 , and the boss 33 is stuck in the square hole 12 .

[0050] In this embodiment, the square hole 12 is located at the center of the receiving groove 11, and the boss 33 is also square and matches the square hole 12; the first fixing member 31 can be a stud, and the second fixing member 32 can be a nut. The boss 33 is welded to the top of the first fixing member 31, i.e., the operating end, and the threaded end of the first fixing member 31 passes through the axial hole between the first pressing block 21 and the second pressing block 23, and then is fixed by the second fixing member 32. It can be understood that under the limitation of the boss 33, when the second fixing member 32 is screwed, the first fixing member 31 will not rotate with it, so that the second fixing member 32 can be quickly tightened or loosened.

[0051] By tightening or loosening the second fixing member 32, the size of the clamping space formed between the first pressing block 21 and the second pressing block 22 and the receiving groove 11 is changed to adapt to wires 60 of different specifications. Similarly, the working principle of the third pressing block 23 and the fourth pressing block 24 is the same.

[0052] In one embodiment of the present invention, an upper shell 50 is hingedly connected to the lower shell 40 , and the upper shell 50 can cover the lower shell 40 .

[0053] In this embodiment, the lower shell 40 is provided with a buckle 43, and the upper shell 50 is provided with a buckle platform 53. When the upper shell 50 is closed, the buckle 43 is buckled with the buckle platform 53. When the lower shell 40 and the upper shell 50 are covered, the entire base 10 can be protected in the shell. The lower shell 40 and the upper shell 50 can be quickly covered in a detachable manner, so that the wire clamp can be easily installed and removed, which greatly reduces the operation time and improves work efficiency.

[0054] In one embodiment of the present invention, a plurality of first arc grooves 41 are respectively provided on both sides of the lower shell 40, and the upper shell 50 is provided with a second arc groove 51 corresponding to each first arc groove 41. When the upper shell 50 is closed, the first arc groove 41 and the corresponding second arc groove 51 form a complete annular hole.

[0055] In this embodiment, each accommodating groove 11 corresponds to two first arc-shaped grooves 41, and the two first arc-shaped grooves 41 respectively correspond to the clamping space between the first pressing block 21 and the side wall of the accommodating groove 11 and the clamping space between the second pressing block 22 and the accommodating groove 11, so that the clamped wire 60 can be exposed outside the lower shell 40 from the first arc-shaped groove 41 and the second arc-shaped groove 51.

[0056] Among them, the edge of the lower shell 40 is provided with a recess 42, and the edge of the upper shell 50 is provided with a convex strip 52. When the upper shell 50 is closed, the convex strip 52 is inserted into the recess 42 to improve the stability of the closure of the lower shell 40 and the upper shell 50, so that the upper shell 50 will not be relatively offset from the lower shell 40 when the upper shell 50 is closed.

[0057] Working principle: When temporary power connection is required, first open the upper shell 50, then loosen the second fixing piece 32, install the main conductor 60 into the clamping space at one end of the receiving slot 11 in the wire clamp device, and then pass the branch of the conductor 60 through another clamping space. At this time, tighten the second fixing piece 32 until the first pressure block 21 and the second pressure block 22 press the conductor 60 to complete the wiring. If the second branch conductor needs to be connected, use the second receiving slot 11 to load the conductor and tighten the second fixing piece 32. The third pressure block 23 and the fourth pressure block 24 clamp the branch wire to complete the wiring. After the wiring is completed, cover the upper shell 50 to cover the entire base 10, and finally fasten it with the buckle 43 to complete the temporary power connection.

[0058] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
