Technical Field

[0001] This utility model relates to the field of electrical connection equipment, specifically a terminal wire clamp. Background Technology

[0002] In the connection of electrical equipment terminals, terminal wire clamps are commonly used wire fixing devices. They achieve electrical connection and mechanical fixation by using bolts and limit clamps to compress the wires.

[0003] For example, Chinese patent application CN201520204050.1 discloses a terminal wire clamp, which includes a base, a wire clamp and a screw installed in the base, and a top cover with a through hole on the base. The upper end of the wire clamp has a threaded through hole, and the screw includes an externally threaded portion that mates with the internal thread of the wire clamp and a non-threaded portion. The end of the non-threaded portion contacts a contact plate inside the wire clamp. The screw of this invention includes both a threaded portion and a non-threaded portion. When the screw is loosened and removed, it will not damage the base and top cover, and the screw will not fall out. This facilitates product installation and use while saving product space and materials.

[0004] However, in actual use, when the wire is placed on the surface of the wire clamp, it is fixed by tightening the limit clamp with bolts. Due to the lack of an effective positioning structure, the wire is prone to shaking during placement and fixing, resulting in inaccurate positioning and reduced construction efficiency. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-6 As shown, this utility model provides a terminal wire clamp, including a clamp body 1, and a groove 2 is formed on the surface of the clamp body 1;

[0028] like Figure 1 , 4 As shown, a fixing component 3 is provided on one side inside the groove 2 to prevent the wire from shaking and achieve precise positioning. The fixing component 3 includes a fixing sleeve 31, and a threaded adjusting bolt 32 is provided at the center of the surface of the fixing sleeve 31. An arc-shaped fixing block 33 is connected to the bottom of the threaded adjusting bolt 32. The fixing sleeve 31 is installed on one side inside the groove 2. The fixing sleeve 31, the threaded adjusting bolt 32 and the arc-shaped fixing block 33 are used to limit the wire.

[0029] By setting the fixing component 3, a threaded through hole adapted to the threaded adjusting bolt 32 is opened on the surface of the fixing sleeve 31. The threaded adjusting bolt 32 is rotatably connected to the arc-shaped fixing block 33 through the rotating shaft. In use, when the wire is placed inside the groove 2 and one end of the wire is pushed into the inside of the fixing sleeve 31, the threaded adjusting bolt 32 is rotated to drive the arc-shaped fixing block 33 to press and fix one end of the wire inside the fixing sleeve 31. The anti-slip texture of the arc-shaped fixing block 33 can increase the friction with the wire and prevent the wire from sliding axially.

[0030] like Figure 1 , 3As shown in Figures 5 and 6, movable components 4 and pressing components 6 are respectively provided on the left and right sides of the surface of the clamping plate body 1. The movable component 4 includes a threaded rod 41, a movable sleeve 42 is sleeved on the surface of the threaded rod 41, and a threaded connecting sleeve 43 is threadedly connected to the surface of the threaded rod 41 and above the movable sleeve 42. The threaded rod 41 is connected to the surface of the clamping plate body 1 and is vertically fixed to the surface of the clamping plate body 1. The movable sleeve 42 is sleeved on the threaded rod 41 and can slide up and down. The threaded connecting sleeve 43 is screwed onto the threaded rod 41 and is located above the movable sleeve 42.

[0031] like Figure 1-3 As shown in Figures 5 and 6, the extrusion assembly 6 includes a threaded bolt 61, a connecting sleeve 62 is fitted on the surface of the threaded bolt 61, and a threaded sleeve 63 is threadedly connected to the surface of the threaded bolt 61. A limiting assembly 5 is provided between the movable assembly 4 and the extrusion assembly 6. The limiting assembly 5 includes an arc-shaped limiting frame 51, and a rubber pad 52 is adhered to the arc-shaped limiting frame 51. One end of the arc-shaped limiting frame 51 is connected to one side of the movable sleeve 42, and one side of the connecting sleeve 62 is connected to the other end of the limiting frame 51. One end of the arc-shaped limiting frame 51 is fixedly connected to the side of the movable sleeve 42, and the other end is connected to the extrusion assembly 6 through the connecting sleeve 62. The rubber pad 52 is adhered to the inner arc surface of the arc-shaped limiting frame 51 and is made of silicone rubber, which has high elasticity and wear resistance.

[0032] By setting up the movable component 4, the limiting component 5, and the pressing component 6, the movable sleeve 42 can be used to facilitate the use of the arc-shaped limiting frame 51. It is first movably connected to the surface of the clamping plate body 1 through the threaded rod 41. The use of the threaded rod 41 and the threaded connecting sleeve 43 facilitates the pressing of the movable sleeve 42 to press and fix the arc-shaped limiting frame 51. An installation through hole adapted to the threaded bolt 61 is opened on one side of the clamping plate body 1. The use of the threaded bolt 61 and the threaded sleeve 63 can fix the arc-shaped limiting frame 51. The use of the rubber pad 52 can increase the friction when the arc-shaped limiting frame 51 contacts the wire.

[0033] In use, after the wire is placed inside the groove 2 and fixed by the fixing component 3, the threaded connecting sleeve 43 is rotated downward on the surface of the threaded rod 41. When the threaded connecting sleeve 43 moves downward on the surface of the threaded rod 41, it pushes the movable sleeve 42 to move downward on the surface of the threaded rod 31. When the movable sleeve 42 moves downward, it drives the arc-shaped limiting frame 51 to move downward, so that the arc-shaped limiting frame 51 with rubber pad 52 contacts the wire. After the arc-shaped limiting frame 51 with rubber pad 52 contacts the wire, the threaded bolt 61 is passed through the connecting sleeve 62 and the clamp body 1 at the other end of the arc-shaped limiting frame 51. Finally, the threaded sleeve 63 is used to thread the threaded bolt 61 to fix the arc-shaped limiting frame 51 to the wire.

[0034] After the wire is initially positioned by the fixing component 3, the threaded connecting sleeve 43 is rotated downwards. The threaded connecting sleeve 43 moves down along the threaded rod 41 and presses against the movable sleeve 42. The movable sleeve 42 drives the arc-shaped limiting frame 51 to move downwards, so that the rubber pad 52 fits against the surface of the wire. At this time, the rubber pad 52 generates lateral pressure due to elastic deformation, further restricting the swaying of the wire in the groove 2. The threaded bolt 61 passes through the preset installation through hole of the clamp body 1, the connecting sleeve 62 is fixed to the other end of the arc-shaped limiting frame 51, and the threaded sleeve 63 is screwed onto the threaded bolt 61. Pass the threaded bolt 61 through the through hole of the connecting sleeve 62 and the clamp body 1, ensuring that the other end of the arc-shaped limiting frame 51 is tightly fitted with the clamp body 1. Tighten the threaded sleeve 63, and the tension of the threaded bolt 61 will cause the arc-shaped limiting frame 51 to be pressed towards the clamp body 1 as a whole. At this time, the rubber pad 52 is compressed, generating uniform radial pressure, which firmly fixes the wire in the groove 2. The amount of compression of the rubber pad 52 can be adjusted by the tightness of the threaded sleeve 63 to avoid excessive compression and damage to the wire insulation layer.

[0035] When disassembly or maintenance is required: loosen the threaded sleeve 63, remove the threaded bolt 61, release the fixing of the arc-shaped limit bracket 51, rotate the threaded connecting sleeve 43 upward, the movable sleeve 42 drives the arc-shaped limit bracket 51 to move upward and separate from the surface of the wire, rotate the threaded adjusting bolt 32 counterclockwise, the arc-shaped fixing block 33 moves upward, release one end of the wire, and the wire can be taken out for replacement or repair.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
