Detailed Description

The invention will be described in detail below with reference to the drawings in combination with embodiments.

As shown in fig. 1 to 4, a compact quick wiring connector comprises a housing 1, a wire inlet hole 2 is formed in the housing 1, a combined spring plate and a spring plate switch 3 are arranged in the housing 1, the combined spring plate is composed of an upper spring plate 4 and a lower spring plate 5, an elastic wire passing gap 45 is formed between the upper spring plate 4 and the lower spring plate 5 through elastic deformation, a wire passing opening 41 is formed in the upper spring plate 4, the wire passing opening 41 corresponds to the wire inlet hole 2 in the housing 1 and is used for guiding wires to penetrate into the elastic wire passing gap 45, one end of the lower spring plate 5 is adjacent to the spring plate switch 3, and the spring plate switch 3 drives the lower spring plate 5 to deform so as to change the size of the elastic wire passing gap 45 and clamp or loosen the penetrated wires.

The rear sections of the upper spring plate 4 and the lower spring plate 5 are fixedly connected to the inner side wall of the shell 1, the middle section of the upper spring plate 4 is provided with the wire through opening 41, the front sections of the upper spring plate 4 and the lower spring plate 5 form a clamping extension 451 for prolonging the clamping length, and the part forming the elastic wire through opening 45 at least comprises the middle sections of the upper spring plate 4 and the lower spring plate 5 and the clamping extension 451.

The middle section of shell fragment switch 3 is equipped with rotation portion, and shell fragment switch 3 sets up in casing 1 through the recess that corresponds the setting on rotation portion and the casing 1 rotationally, in this embodiment, rotation portion of shell fragment switch 3 is circular to the integrative pivot that is equipped with in the rotation portion for rotate in the recess that corresponds on casing 1, the anterior segment of shell fragment switch 3 and the anterior segment of lower shell fragment 5 abut on for push/pull down shell fragment 5 when shell fragment switch 3 rotates, the rear segment of shell fragment switch 3 is outside casing 1 through the logical groove that corresponds the setting on casing 1, and the logical groove on casing 1 provides the rear segment toggle stroke of shell fragment switch 3.
