Detailed Description

The invention will be further described by way of examples with reference to the accompanying drawings:

as shown in FIGS. 1-4, a novel three way connection, including three way connection main part 1, three way connection main part 1 is gone to left to extend and is provided with first joint 2, three way connection main part 1 is gone to right to extend and is provided with second joint 3, the lower extreme of three way connection main part 1 sets up to third joint 4, first joint 2, second joint 3 and third joint 4 communicate each other, and first joint 2, second joint 3 bilateral symmetry set up, above for prior art, no longer describe herein.

The three-way joint comprises a three-way joint body 1, a mounting protrusion 5, an electrostatic groove 5a for inserting an electrostatic terminal 6, a clamping groove 5b communicated with the electrostatic groove 5a, an elastic clamping protrusion 6a, a clamping protrusion 6a and a clamping groove 6 b, wherein the three-way joint body 1 is formed by conducting plastic in an injection molding mode, the upper end of the three-way joint body 1 is provided with the mounting protrusion 5, the front side face of the mounting protrusion 5 is horizontally provided with the electrostatic groove 5a, the rear end of the clamping protrusion 6a is fixed on the electrostatic terminal 6, and the front end of the clamping protrusion 6a extends upwards in an inclined mode and a gap is reserved between the clamping protrusion and the electrostatic terminal 6; when the electrostatic terminal 6 is mounted in the electrostatic slot 5a, the front end of the engaging projection 6a just abuts against the front inner side wall of the engaging slot 5 b.
