Intelligent mould is at present, there are few amount and PCB terminal blocks, but represents a new mold technology direction, products in the industry structure adjustment and expand to more and more important role. Intelligent mould well, must be to promote the whole play strong role in driving the mold industry, therefore, the priority in an intelligent mould industry is necessary. Thought USES the higher-end mold, terminal industry is imperative. In order to ensure the quality and reliability of the terminal, the fatal weakness of attack prevention, proposal according to the product technical conditions, formulate corresponding selection techniques entreaty, expand the following reliability test targeted to prevent failure. At present, the common terminal consumer manufacturer product acceptance test without this project, and after user installed ordinary all demand to suspend the conduction test. So proposal consumer manufacturer of some of the key models of product should be increased. Some of the terminal is used in dynamic vibration environment. Real test proved that using only static contact resistance test whether qualified, does not guarantee under dynamic environment by contact and reliable. , often qualified adapter contact resistance on the suspension vibration, shock, etc still offers a transient simulation experiment infix electricity phenomenon, therefore, to the terminal of some high reliability supplications, dynamic vibration experiment examination the contact reliability. Power of single-hole respectively refers to insert in the state of the contact is changed from static to exercise force, respectively, of the pin and socket is to evaluate the contact.
A le enterprise experiments indicate: single-hole force is too small, respectively in the vibration and impact load that may constitute a signal transient breaking. Check the contact reliability using the method of measuring puckering force respectively than measuring contact resistance is effective. Examination revealed a single force out-of-tolerance jack respectively, often still qualified measurement of contact resistance. Therefore, should not be used for heavy pulling force testing machine more neat, prevent individual jack up signal transient breaking relaxation. Raw material quality of the edge body do impact on the performance. So about the choice of raw materials manufacturers especially important, do not blindly to reduce capital and loss of material quality. Should choose metal material with good credit. And for each batch of material incoming material to prove, and other important information. Use the traceability information. At present, there are some consumption plant process rules again after assembly into waste detection performance, the results for all the flange body itself with reason resistance differences, the whole batch of waste scrap.
