Crimping device and method for PCB connector

Abstract

The invention relates to a crimping device and method for a PCB connector, and relates to the technical field of machining. The invention solves the problem of pin crimping of a novel fisheye-shaped connector. Segmented crimping with a specified stroke is carried out by using a crimping machine during crimping. The crimping device has a limiting function, and the limiting design is carried out inthe length and width directions of a plastic shell based on a connector base, so that the crimping is more accurate after the limitation is carried out on two degrees of freedom, and the crimping device can be ensured not to pressure the pin. The structure and size of the crimping device are designed to ensure that the pin outlet rate after crimping reaches 100%, the phenomenon of pin shrinkage isavoided, the reliability is high through inspection and power-on test, and the required electrical property and mechanical property are ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a crimping device and method for a PCB board connector. Background technique [0002] Electrical connectors are mounted on PCB boards (PCB boards such as Figure 4 As shown), the components on the circuit are an indispensable part of electronic equipment. They not only serve as a communication bridge between the original isolated circuits in the circuit, so that the current can flow, but also play a stable connection and provide The role of high reliable plug-in times. [0003] The commonly used shape of the traditional connector terminal part is a cylindrical pin with the same pin direction, and the length of each connector is equal. The connector crimping method is to use a traditional crimping device (such as Figure 5 Shown) crimp each connector unit sequentially to form a set of connector plugs. [0004] New fisheye pin connectors (such as figure 1 shown) c...

AI Technical Summary

Problems solved by technology

[0004] New fisheye pin connectors (such as figure 1 shown) cannot be crimped with conventional crimping devices such as Figure 5 Shown) Press out 100% of the pins, pin shrinkage will appear, and the fisheye connector plugs have different lengths depending on the connector model (such as figure 2 and image 3 Shown are two kinds of fisheye connector plugs), a PCB board will consist of two different lengths of fisheye connector plugs

And the new fish-eye connector is an independent innovative domestic pin, which has not been widely used at present, so its installation and use have become difficult. The characteristic of this type of connector is that the fish-eye pin is wider than the cylindrical pin. It is necessary to set the crimping stroke and limit the connector to ensure that the pins will not be mispressed by the crimping device during crimping, and it is necessary to increase more contact area between the crimping device and the PCB board to ensure the Pins are pressed out

When the installation direction of the pins of the fisheye connector is inconsistent (such as image 3 As shown), two groups of pins in different positions are at 90 degrees to each other, and the front row has no supporting point, so it is easy to cause pin shrinkage during crimping
