Abstract
Description
Technical Field
[0001] This utility model relates to the field of radio frequency connector technology, and in particular to an RF connector housing fitting and welding structure. Background Technology
[0002] The existing technology on the market only has a shell. After the shell is bent, the plastic is positioned. The bending size is difficult to stabilize and the stress on the plastic cannot be well controlled. When the product is put on the board, the plastic deforms due to heat and cannot effectively support the terminals. The terminals are subjected to abnormal stress, the product function is unstable, and the yield is low. Utility Model Content

[0005] Furthermore, welding grooves that cover the welding area are provided on both the left and right sides of the front and rear ends of the lower iron shell.
[0006] Furthermore, the welding area and the welding fitting groove are fixed by welding.
[0007] Furthermore, the large terminal includes a straight portion and a bent portion, the straight portion being connected to the bent portion, and the bent portion being fastened into the opening at the left end of the upper plastic.
[0008] Furthermore, a positioning buckle is provided on the lower plastic, and a first positioning hole that matches the positioning buckle is provided on the large terminal.
[0009] Furthermore, the upper iron shell includes an H-shaped base plate and side plates. The side plates are located on the left and right sides at the front and rear ends of the base plate. The side plates have a welding fitting groove at their inner end. The bottom surface of the lower plastic has an installation groove that matches the H-shaped base plate. A positioning post is provided in the middle of the bottom of the installation groove. The bottom of the base plate has a second positioning hole with a corresponding position.
[0010] Furthermore, a small terminal is provided at the bottom right end of the upper plastic.
