Detailed Description
The invention will be further described in the following with reference to the accompanying drawings in which:
referring to fig. 1 to 5, a binding post, including copper head 1 and aluminium bar 2, copper head 1 is the cylinder, and one side of cylinder is provided with plane 11 along the axis direction of cylinder, be provided with recess 12 that a plurality of equidistance set up on plane 11, recess 12 is horizontal setting, and the screw of being convenient for through setting up of plane 11 and recess 12 is fixed to binding post, and recess 12 plays the skid-proof effect of increase frictional force, avoids binding post and the equipment to take place the condition that breaks away from after passing through the screw fixation, increases the safety in utilization performance.
Further setting the following steps: the second plane 13 is arranged on the other side of the cylinder along the axis direction of the cylinder, the second plane 13 and the first plane 11 are arranged in a mirror image mode, the contact area is increased when the connection and the fixation are conducted through the increase of the second plane 13, and the bidirectional screw locking is achieved.
Further setting the following steps: the second groove 14 with a plurality of equal distances is arranged on the second plane 13, the second groove 14 is transversely arranged, the second groove 14 further plays a role in increasing the friction force and preventing skidding, the situation that the wiring terminal is separated from the equipment after being fixed through screws is further avoided through the double-sided groove, and the use safety performance is further improved.
Further setting the following steps: the first groove 12 and the second groove 14 are arranged in parallel, and the first groove 12 and the second groove 14 can be arranged in parallel in an overlapped mode or in a staggered mode, namely the second groove 14 is correspondingly arranged between the two first grooves 12.
