Insertion and extraction force testing device

Abstract

The embodiment of the invention discloses an insertion and extraction force testing device, which comprises an upright, a force sensor, an upper fixture, a lower fixture, a driving unit and a control unit, wherein the control unit comprises a data extraction module, a touch display screen and a control module; the data extraction module is connected with the force sensor for extracting testing information of the force sensor; the touch display screen is used for displaying a control interface and inputting a control instruction, and connected with the data extraction module for displaying testing data obtained by the data extraction module in real time; and the control module is connected with the driving unit for controlling the driving unit to run according to the control instruction. The insertion and extraction force testing device is simple in structure, easy and simple to operate, high in stability, and low in use cost and manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to an insertion force testing device. Background technique [0002] Many data cables, power cables and other connecting cables used in conjunction with mobile phones, computers, servers and other electronic devices, as well as various mobile electronic devices such as U disks, need to be tested for the insertion and extraction force between the corresponding plugs and sockets during the manufacturing process. , to ensure that it meets the specific requirements of each connector. With the continuous development of science and technology, the insertion and extraction force has been developed from traditional manual and semi-automatic to fully automatic. [0003] The existing fully automatic connector insertion force testing machine is composed of two parts: the host computer and the control terminal that complete the test action. The control terminal is an additionally configured com...

Problems solved by technology

[0005] 1. High cost of use: the price of the mainframe of the existing automatic connector insertion force testing machine is relatively high, and at the same time, it is necessary to purchase a computer, related accessories and testing software systems, etc., which will undoubtedly increase the use cost of the insertion force testing machine;

[0006] 2. Higher requirements for operators: to use the existing fully automatic connector insertion force testing machine, the operator must have certain computer operation skills to be able to use the test software system proficiently. At the same time, the operator is also required to be able to handle the test Various problems in the daily use of the software system and computer system to ensure the normal progress of the test operation;

[0007] 3. The instrument is bulky, the stability is not high, and the manufacturing cost is high: the existing automatic connector insertion force testing machine is equipped with thick steel double guide posts with a diameter of 40mm and a thick steel movable guide sleeve with a diameter of 68mm. The weight of the main body of the instrument reaches 108.9KG, and the large-sized steel parts and supporting parts arranged on the upper part of the testing machine case greatly increase the weight of the upper part of the case. , will affect the stability of the screw due to the excessive weight of the movable guide sleeve, thereby reducing the overall stability of the machine; in fact, the international standard electrical connector insertion force is set below 122.5N, while the existing test The machine can withstand a load of up to 31000N (from the performance level of the M24 thread connection at the bottom part of the fixed and locked double guide column), which is more than two hundred times the actual demand of the test machine, far exceeding the actual demand strength of the test machine, high load The configuration can not be fully utilized, but it increases the manufacturing cost of the tester
