The left and right sides of the inside of the sealing paste groove 12G are respectively provided with a first main line hole 12A and a second main line hole 1BA which are flush with each other. The inner side of the sealing paste groove 12G is also provided with a branch line hole 12E which is flush with the first main line hole 12A in front and back.

[0041] By providing the first process groove 11F and the second process groove 11G, shrinkage and deformation can be reduced during the injection molding process of the housing 11 .
[0042] According to the above description, the cylindrical plug 132 is made of plastic, and a plug-in groove 132A is provided at the bottom of the cylindrical plug 132. The top of the metal piercing piece 131 is inserted into the plug-in groove 132A and fixed. The top of the cylindrical plug 132 and the circular groove 141D are clearance-fitted. The bottom of the metal piercing piece 131 is respectively provided with a main line piercing blade 131A and a branch line piercing blade 131B for piercing the main line 21 and the branch line 22.
