Problems solved by technology

However, for relays with large currents, due to too many types of pin arrangements, the existing technology has not yet achieved the reliable contact requirements of the test by using fixtures or sockets, and it is still necessary to manually solder the wires with an electric soldering iron

Embodiment Construction

[0045] The pin connection device of the present invention is used for relays, through the modularization and flow of relay pin welding methods, and through the restriction of the shaking of the relay 9 during the test process, it meets the requirements of various relay tests and improves the test performance. Efficiency and reduced labor costs. Such as Image 6 with Figure 9 As shown, the pin connection device mainly includes a double-sided circuit board 1 , a welding base 2 , a fixed shell 5 , and a workpiece tray 6 .

[0046] Such as figure 1 As shown, the double-sided circuit board 1 is arranged such that one side has solder joints for wires, and the other side has a plurality of pads that are consistent with the pin arrangement of the relay. Each pad corresponds to a relay pin and connects to a wire soldered to a wire pad. Since on a double-sided circuit board 1, the positions of multiple welding pads can be changed according to the set positions, therefore, the doubl...

Abstract

The invention provides a pin connecting device and method for a relay, and relates to the technical field of electronics, and the device comprises a double-sided circuit board, one side of which is provided with wire welding spots and the other side of which is provided with bonding pads consistent with relay pins in arrangement; a welding base being of a first hollow structure which is communicated up and down and is provided with an inner side and an outer side, the inner side is matched with the double-sided circuit board in shape, and a first step for supporting the double-sided circuit board is arranged on the inner side; a fixed shell, provided with an internal space used for limiting shaking of the relay shell, and the fixed shell and the welding base are connected to form an integrated structure. Under the condition of relay testing, the wire is welded to one side of the double-sided circuit board, the relay pins are welded to the other side of the double-sided circuit board, the double-sided circuit board is fixed to the welding base, and when the welding base is connected with the fixed shell, the relay enters the inner space of the fixed shell. According to the invention, diversified relay test requirements can be met, the test efficiency is improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a pin wiring device and a wiring method for a relay. Background technique [0002] A relay is a switching component, usually with multiple pins. There will be some differences in the pin arrangement and quantity between different types of relays. During relay testing and testing, the pins of the relay are usually connected to special testing and testing equipment through wires. For high-grade electromagnetic relays, there will be vibration tests in the test items. The vibration test requires online testing of some properties of the electromagnetic relay during the vibration process. [0003] However, during the vibration process, if the test socket corresponds to each pin as an elastic contact, these contacts may experience short-term poor contact due to vibration, thereby causing a change in current. In the test, it is impossible to distinguish whether the current change...
