Detailed Description

The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, a switching device's wiring structure, includes casing 1, the terminal surface is equipped with entrance hole 11 before the casing, be equipped with in the casing with holding tank 2 of entrance hole intercommunication, be equipped with lug 3 and elastic wire clip 4 in the holding tank, the wire clip with form the wire clamping groove 31 that is used for pressing from both sides tight wire between the lug, wire clip bottom for be used for with the pointed end 41 of wire contact. The pressure of pressing from both sides tight wire is out of shape by the line ball piece and is produced, and the line ball piece bottom is equipped with the pointed end simultaneously, does not have the fillet, prevents that the wire from extracting easily.

In this embodiment, as shown in the figure, the front end surface of the housing is further provided with an auxiliary hole 12 for an auxiliary tool to extend into, and the auxiliary hole is arranged corresponding to the middle end of the line pressing piece. The wire can be taken out by pushing the wire pressing sheet by a screwdriver or the like.

In this embodiment, as shown in the figure, still include the wire frame 5, the wire frame with the holding tank inner wall corresponds the setting, be equipped with the logical groove 51 that is used for the lug to pass on the wire frame. Compact structure and convenient installation.

In this embodiment, as shown in the figure, the wire pressing piece is integrally provided with the wire frame. Is convenient for manufacturing.

In this embodiment, as shown in the figure, a bump 21 is disposed in the accommodating groove, a rear end face of the pressing piece corresponds to the bump, and a front end face of the pressing piece corresponds to an inner wall of a front end of the housing. The front and back directions of the wire pressing pieces are limited, and the wire pressing pieces are convenient to use.

In this embodiment, as shown in the figure, the bottom of the accommodating groove is provided with a groove 22, and the bottom of the wire frame is provided with a bottom plate 52 in limit fit with the groove. The bottom plate is arranged in the groove and is limited.

In this embodiment, as shown in the figure, a first arc surface 53 is arranged at a joint of the wire pressing piece and the wire frame, and a second arc surface 211 corresponding to the first arc surface is arranged on an outer wall of the bump. Better contact when the line ball piece is out of shape, the result of use is better.

In the present embodiment, as shown in the drawings, a fuse includes a wiring structure of a switching device as described above.
