Detailed Description
The following describes in detail the preferred embodiments of the present invention with reference to the accompanying drawings.
A copper bar quick clamping device comprises a protective shell 1, a fixing assembly 2, a sliding compression assembly 3 and a locking assembly 4.
As shown in fig. 1 and 2, the protective case 1 is divided into an upper case 11 and a lower case 12, and the upper case 11 and the lower case 12 are fixed by a screw 13.
The tops of the upper shell 11 and the lower shell 12 are provided with groove-shaped openings for facilitating copper bar insertion; the bottoms of the upper shell 11 and the lower shell 12 are provided with wire through holes, so that the connection of cables is facilitated.
The upper and lower cases 11 and 12 are made of an insulating material, preferably insulating ABS.
The fixing assembly 2 comprises a frame 21, an elastic clamping block 22, a sliding sleeve 23 and a second screw 24.
As shown in fig. 3 and 4, the frame 21 is Y-shaped, and has a screw hole 211 and a limiting slot 212 on the left side for fixing the elastic clamping block 22. A cable jack 213 is provided in the middle. A hinge hole 214 is provided on the right side for fixing the cam 33 and the pawl 41, and a cable pressing joint 215 is provided on the bottom. The connection between the cable connector 215 and the cable in the present invention is not limited to the crimping, but may be a copper nose connection.
The frame 21 is preferably made of brass.
As shown in fig. 5 and 6, the elastic clamping block 22 is trapezoidal in shape and has an elastic clamping surface 221, and in the state of clamping the copper bar, the elastic clamping surface is elastically deformed, and the shape of the elastic clamping surface is changed from trapezoidal shape to rectangular shape, so that the clamping moment of the copper bar is increased, and the effective contact area of the copper bar is ensured. The elastic clamping block 22 is T-shaped, a threaded hole 223 is formed in the boss 222, and the boss 222 and the limiting clamping groove 212 are used for being matched to play a limiting role.
The elastic clamping block 22 and the frame 21 are fixed by the second screw 24 only in an optimal scheme, so that the elastic clamping block 22 can be conveniently replaced after being worn. It may also be in the form of an integral structure of the resilient clamping block 22 and the frame 21.
The elastic clamping block 22 is preferably made of brass, and the surface of the elastic clamping surface 221 is preferably embossed so as to increase the contact area of the conductor.
The sliding compaction assembly 3 comprises a sliding rod 31, a connecting rod 32, a cam 33 and a hinge pin 34, the sliding compaction assembly 3 and the fixing assembly 2 form a crank slide block mechanism, and the sliding of the sliding rod 31 is transmitted through the connecting rod 32 and finally converted into the rotation of the cam 33. The cam 33 and the fixing assembly 2 form a cam clamping mechanism, so that the copper bar is clamped.
The top of the slide bar 31 is provided with a T-shaped platform which is used as a surface matched with the copper bar, the protruding part of the T-shaped platform is arranged in the limiting clamping groove 212, and the slide bar 31 can slide downwards along the sliding sleeve 23 under the action of the reaction force of the copper bar.
The connecting rod 32 is connected with the slide rod 31 and the cam 33 through the hinge pin 34.
The number of the connecting rods 32 is two, and the connecting rods are respectively arranged on the front side and the back side of the sliding rod 31.
As shown in fig. 7, the circular arc edge of the cam 33 is a pressing surface 331, and the lower end is provided with a ratchet 332. The gap between the process pressing surface 331 and the elastic clamping surface 221, in which the cam 33 rotates counterclockwise, is reduced accordingly, thereby functioning to clamp the copper bar.
The compression surface 331 is provided with an anti-slip structure, and embossing treatment is adopted in the present invention.
The ratchet 332 is engaged with the pawl 34 to prevent the cam 33 from rotating clockwise.
The cam 33 is fixed to the frame 21 by a hinge pin 34.
The locking assembly 4 comprises a pawl 41 and an unlocking pull cord 42. The pawl 41 is secured to the frame by a hinge. And a return spring is provided between the pawl 41 and the frame 21. The pawl 41 cooperates with the ratchet teeth 332 on the cam 33 to ensure that the cam 33 can rotate counter-clockwise and lock clockwise.
When unclamping is required, only the unlocking string 42 needs to be tensioned. The pawl 41 can be disengaged to unlock the lock.
The unlocking rope 42 is made of an insulating material, preferably an insulating nylon rope.
In operation, as shown in FIG. 2, the gap between the pressing surface 331 and the elastic clamping surface 221 is first determined according to the thickness of the copper bar and adjusted, and the gap should be 2-5mm greater than the thickness of the copper bar. And aligning the rectangular notch at the upper part of the copper bar rapid clamping device with the copper bar, and then forcefully pushing the rapid clamping device. After the copper bar contacts with the slide bar 31, the slide bar 31 moves downwards along the slide sleeve 23 under the action of the reaction force of the copper bar. The connecting rod 32 drives the cam 33 to rotate anticlockwise under the driving of the slide rod 31. The gap between the pressing surface 331 and the elastic clamping surface 221 is continuously reduced as the cam 33 rotates counterclockwise to play a role of clamping the copper bar. As it goes deeper, the elastic clamping surface 221 of the elastic clamping block 22 is elastically deformed. This increases the clamping force of the copper bar on the one hand and the contact area on the other hand. When the elastic clamping block is deformed from a trapezoid shape to a rectangle shape, the copper bar clamping device cannot be pushed forward any more. The ratchet 332 and the ratchet 41 cooperate to prevent the cam 33 from rotating in the opposite direction during this process, thereby functioning as a fixed lock. The operation process of the copper bar quick clamping device connected with the copper bar is finished. When the copper bar needs to be separated from the copper bar, only the unlocking rope 42 needs to be tensioned, the ratchet 41 is in an unlocking state, the cam 33 can rotate clockwise, the copper bar quick connecting device is pulled out forcibly, the pressing surface is driven by the cam to rotate clockwise under the action of friction force, the gap between the pressing surface 331 and the elastic clamping surface 221 is enlarged, and the elastic clamping surface 221 recovers elastic deformation. Finally, the separation of the copper bar and the quick copper bar clamping device is realized.
