An automatic detection device for a backplane connector

Abstract

The invention relates to an automatic detecting device for a backboard connector. The device is equipped with an upper computer, a charging and discharging unit, a detecting unit, a clamp, a movement control unit and a transmission unit; the detecting unit comprises an appearance detecting unit, a precise measuring unit and an inserting drawing force measuring unit. The device is able to detect the key parameters which influence the electrical connecting performance of the backboard connector, including reading the silk-screen information, detecting appearance damage and scratch, measuring the true position of an inserting pin, measuring the true position of a pin, measuring opening dimension of a spring plate, detecting position of the spring plate in an inserting hole, and measuring inserting and drawing force of the inserting hole. With the adoption of the device, the whole detecting process can be automatically performed; in addition, the average detecting time of single backboard connector is reduced by the mode of multi-station synchronous working, and the detecting efficiency can be effectively increased.

Description

technical field [0001] The invention relates to a device capable of automatically detecting key parameters affecting the electrical connection performance of a backplane connector. Background technique [0002] The backplane connector is an electrical connector used to connect single boards and backplanes. It is mainly used to transmit high-speed differential signals, single-ended signals and high currents. It is widely used in large-scale communication equipment, high-performance servers, large-scale computers, industrial Computers and high-end storage devices. [0003] In order to ensure the quality of the product, it is necessary to detect the key parameters that can affect the electrical connection performance of the backplane connector before using the backplane connector. The detection content mainly includes the following three aspects: [0004] (1) Appearance inspection. Check whether the appearance of the backplane connector is complete. If the appearance is damag...

Problems solved by technology

The existing insertion force measurement device mainly adopts the following two measurement methods: ① Use the paired male connector as the test terminal to measure the overall insertion force of the backplane connector. This method has fast measurement speed and high efficiency, but the overall insertion force The pull-out force is an overall effect. If the overall pull-out force is qualified, it cannot guarantee that each socket is in good contact, and for a backplane connector with a large number of sockets, the overall pull-out force is large, and the clamping force of the fixture is required to be large. Too large The clamping force is easy to cause damage to the connector shell; ②Measure the single-hole insertion force of the backplane connector. Although this type of device can avoid the disadvantages of the overall insertion force measurement, the existing such devices are semi-automatic It is necessary to manually align each jack before measurement, which is cumbersome and inefficient.
