Description

Clamping type wiring terminal structure Technical Field The utility model relates to the technical field of wiring terminals, in particular to a clamping type wiring terminal structure. Background The existing wiring terminal has the defects of easiness in loosening, complexity in mounting, poor compatibility, weak vibration resistance and the like of the cable, and is characterized in that the traditional crimping is dependent on manual alignment and lacks of self-locking guide, so that stress is uneven, an insulating layer is easy to damage, a single-point locking structure cannot adapt to wire diameter change, the cable is often damaged due to hard separation during maintenance, and the cable is frequently failed under the vibration environment due to insufficient thread looseness prevention. In multi-strand twisted conductor fastening operations, strand discretization is a common process challenge. Part of constructors are forced to correct the shape by adopting an unconventional bending method for solving the problem of loose stranded wire structure. The improper operation not only can reduce the assembly efficiency, but also can cause hidden defects to be formed in the conductor, and the actual measurement shows that the abnormal contact resistance generated by the improper operation can raise the temperature of a connecting point by 60-120 ℃ compared with the standard process, thereby causing the problems of line loss multiplication and local overheating. This effect of malignant temperature rise has constituted a significant electrical fire risk. In view of the above, in order to overcome the above technical problems, the present utility model provides a clamping type terminal structure, which solves the above technical problems. Disclosure of utility model The self-locking type cable guide device has the technical purposes that the natural cross guide channel is formed by the staggered arrangement of the threading holes of the compression blocks and the grooves of the limiting blocks, the cables automatically cross after penetrating, the self-locking type cable guide device is fixed in a self-locking mode, external force pulling is effectively resisted, and the cable is prevented from loosening. In order to achieve the technical purpose, the utility model provides the following technical scheme: The utility model provides a clamping type wiring terminal structure which comprises a base and a compression block, wherein two limiting blocks are fixedly arranged above the base, the two limiting blocks are positioned at the middle positions of two ends of the base, the compression block is slidably arranged between the two limiting blocks, the threading holes of the compression block and the grooves of the limiting blocks are in space staggered layout, and natural cross guidance is formed through a hole slot dislocation structure, so that self-locking type cross wiring of cables is realized. Preferably, a limiting groove for limiting the sliding of the compression block is formed in the base, the limiting groove is located between the two limiting blocks, the cross section of the limiting groove is rectangular, and a sliding groove is connected in the middle of the center of the limiting groove. Preferably, a groove is formed above the limiting block, and the cross section of the groove above the limiting block is arc-shaped. Preferably, the middle of the compression block is provided with a threading hole, and the two ends below the compression block are provided with arc grooves, and the limiting block can slide in the arc grooves formed by the compression block.
