Embodiment Construction

[0023] refer to Figure 1-Figure 6 . In the preferred embodiment described below, a high-density PCB board plug-in high-speed signal connector solderless crimping tooling includes: a base plate 8 placed on the base of the crimping machine, and a press-down tool placed on the base plate 8 Die 1, the upper die 2 on the crimping head 7 of the crimping machine. On both sides of the rectangular body seat of the lower die 1, there are fixedly connected the opposite side limiting plate 12 for symmetrically limiting the connector and the end limiting plate 15 for limiting the freedom of the back end. Between the plate 15 and the opposite side limiting plate 12, there is provided a relief groove 16 to avoid insertion interference with the guide pins 36 on both sides of the plug 3, and corresponding connectors are formed on the inner sides of the two opposite side limiting plates 12 The protruding rail slide bars 32 on both sides of the back plate of the plug 3 are inserted into the l...

Abstract

The invention provides a welding-free crimping tool for inserting a high-speed signal connector into a high-density PCB. The crimping tool is quick and reliable in positioning and can be flexibly connected with different plugs and printed circuit boards. According to the technical scheme, one end of the PCB is in threaded connection with plug front side plug lugs to connect the PCB and a connector together, protruding rail sliding strips on the two sides of the connector plug are clamped into lower die limiting sliding grooves in a sliding mode from top to bottom, and the other end of the connector plug fixes the PCB to a bottom plate in a suspended mode through two movable positioning columns on the bottom plate; an upper pressing die is clamped into the connector plug from top to bottom along the protruding rail sliding strips on the two sides of the connector plug to quickly position a connector plug module, and through two crimping convex dies arranged in parallel in side plates at the two ends of the upper pressing die, the upper pressing die presses the PCB to the rectangular stand column and the crimping platform of a lower pressing die by avoiding three parallel and spaced plug front side plug lugs and an optical fiber plug module on the connector plug, so that the welding-free crimping of the high-density PCB inserted into the high-speed signal connector is completed.

Description

technical field [0001] The invention relates to the technical field of electrical interconnection, in particular to a reinforced ultra-high-speed, high-density, high-reliability PCB connector crimping tooling widely used in the communication field, especially the use of automatic crimping machine technology, which can be used in complex printed circuit boards (PCB) The crimping device used to mount crimp connectors. Background technique [0002] From data communication to transportation machinery, crimp connectors have a wide range of applications. Their reliable structure, function, efficient production efficiency, and no thermal stress, no flux residue, no welding short circuit, virtual welding and other defects, have good high-frequency characteristics, no cleaning after assembly, etc., far superior to welding technology Many features make it a very popular connector. An electrical connector is an electromechanical component used to quickly and easily separate or interr...
