Description
Technical Field
The invention relates to the technical field of electric interconnection, in particular to a crimping device widely applied to a reinforced ultra-high-speed high-density high-reliability PCB connector crimping tool in the communication field, in particular to a crimping device for installing a crimping connector on a complex Printed Circuit Board (PCB) by adopting an automatic crimping machine technology.
Background
Crimp connectors have found wide application from data communications to traffic machinery. Reliable structure, function, high production efficiency, no heat stress, no welding flux residue, no welding short circuit, no false welding and other defects, the high-frequency connector has good high-frequency characteristics, does not need cleaning after assembly, and the like, and is far superior to the characteristics of welding technology, so that the high-frequency connector is quite popular. An electrical connector is an electromechanical element used to quickly and easily disconnect or interrupt a current loop. The size and shape of the connector are also varied according to specific needs, and the connector is generally different in size, shape and structural complexity and quality level. The function of the connector determines the various designs and different features of the component, such as the connection process, connection type, durability, insulation between terminals, etc., all to increase the ease of practical connection. In addition, because many connectors must operate in harsh environments, additional protection designs are often added to the construction of such connectors to prevent vibration, extreme temperature differentials, dust, moisture, contaminants, and the like from affecting their proper operation.
With the miniaturization of electronic packages, components and systems, and the high-speed signal transmission, the continuous development of communication technology and the continuous increase of digital signal transmission speed, the continuous reduction of device package size, the increasing requirements on data transmission rate and storage, and the soldering of PCB connectors in terminated form are no longer applicable. The combination of multiple signals and single signals, the design technology of high-speed high-density printed circuit board with voltage, data and other signals can be mixed in one connector, and the design technology of ultra-high-speed connector is accompanied, so that the design technology of high-speed high-density PCB has become a research hot spot and a difficulty of electronic design. With the release of new standards such as PCI-E and RapidIO, the conversion from parallel bus to serial bus is widely applied, so that the PCB wiring density is greatly reduced, the data transmission rate is improved, and the problems of jitter, loss, bit error rate, differential impedance, serial termination layout and the like are brought. With the development of high speed and complexity of digital signal transmission systems, continuous decrease of active element operating voltage and continuous enhancement of functions, a higher number of components are to be integrated on a limited board area. So many components are on a very small size printed circuit board PCB, high Density Interconnect (HDI) technology must be employed or the components must be embedded directly inside the printed circuit board PCB. In high-density wiring, crosstalk phenomenon is serious, magnetic fields between adjacent wires are overlapped together, interference can be generated to cause noise in signal transmission, and the interference phenomenon can be obviously enhanced due to the increase of the thickness of a medium. The wire-to-ground height in modern PCB routing processes has become smaller and smaller, and the thickness can be less than 5 mils, so the thickness reduction of the dielectric is limited to a certain extent. Otherwise, breakdown and other damage may occur. Analysis of high-speed transmission problems of printed circuit boards PCBs, whether high-frequency analog or digital signal transmission, is becoming increasingly important. The ultra-high speed connector is an element arranged on a PCB, is an indispensable part of electronic equipment, and not only plays a role in supporting a communication bridge between isolated and non-connected circuits in the circuits so as to enable current to flow, but also plays a role in firmly connecting and providing high-reliability plug times. For the ultra-high speed connector with high speed and high density interface, the ultra-high speed connector is often affected by high vibration and high impact load in the working process, and the working environment is extremely bad.
The high-speed connector is a type of connector commonly used for large-scale communication equipment, ultra-high performance servers, supercomputers, industrial computers and high-end storage equipment. The transmission of high-speed signals over backplanes and daughterboards, which are commonly used in crimp technology, is a more serious challenge for connector performance. The staking effect caused by the high density array integral grounding connector crimp pins and the PCB vias will cause signal reflection, thereby negatively affecting signal integrity. Generally, for such stub lines, a back drilling process can be used in the design to reduce the length of the via stub, so as to reduce the adverse effect on the high-speed signal line and ensure the integrity of the high-speed signal.
Most of the existing high-speed connectors are single-signal type connectors, namely, one type of connector can only transmit single-signal type signals, and the connector has the advantages of flexible use and convenient selection, but has the defects that when various signals are required to be transmitted between components or systems, different types of connectors are required to be installed between the components or the systems, so that the total space occupied by the connector is large and the weight is large; the mounting heights of the connectors are not uniform, so that the problem of asynchronous plugging of the connectors can be caused when the components or the systems are plugged and connected; particularly, when a plurality of connectors are adopted, assembly errors can occur at the relative positions of the connectors, so that plugging difficulty is caused, and when the connectors are seriously plugged, deformation is caused, so that the reliability of signal transmission between components or systems is affected; therefore, in order to meet the increasingly complex and precise connection requirements of hardware components and systems, LRM photoelectric radio frequency integrated connectors compatible with VPX standards are developed. The integrated photoelectric radio frequency connector is generally formed by combining an optical fiber plug module, a high-speed plug module and a radio frequency plug module, and can also be used for combining different modules according to different design requirements of products. The optical fiber plug module is arranged in the optical fiber plug mounting cavity in a floating manner through rivets, after the optical fiber plug module is assembled on the plug shell, a certain floating amount is arranged in each direction, when the optical fiber plug module and the optical fiber socket module are inserted in opposite directions, the optical fiber plug module and the optical fiber socket module are compensated for by the floating of the optical fiber plug module to align errors, abnormal stress deformation is prevented after the optical fiber plug module and the optical fiber socket module are inserted and combined, so that the alignment accuracy and the attaching compactness of the optical fiber coupling surface in the optical fiber plug module and the optical fiber socket module are ensured, and smooth transmission and lower attenuation of optical signals on the optical fiber coupling surface are ensured; the radio frequency plug module is arranged in the radio frequency plug installation cavity, the fixing ring spring is arranged in the installation hole of the radio frequency plug, the inverted tooth is arranged on the fixing ring spring, the plug of the radio frequency cable is arranged in the radio frequency plug installation hole from the upper end face of the plug shell, and the plug is fixed in the radio frequency plug installation hole through the fixing ring spring.
Along with the higher and higher integration level of the printed circuit board, the main devices for communication between the boards and the cards are increasingly used as high-speed and high-density integrated photoelectric radio frequency connectors, so that the loss of the connectors in the assembly process is reduced, the working efficiency is improved, and the technology is always a major concern. In the reinforced ultra-high-speed high-density high-reliability connector disclosed in Chinese patent application number 202010644712.2, the connector plug does not have positioning pins and positioning pins, the fisheye pins of the high-speed plug module are arranged in a high-density manner, the guiding part of the pins is shorter, the pins are easily affected by vibration in the crimping process, and the pins are separated from the metallized holes of the PCB. The positioning cannot be realized by means of pins. In the prior art, cushion blocks are mainly arranged above the plug and below the PCB, and are pressed by a manual vice or a manual press, and the cushion blocks are required to be installed and detached once every time of pressing, so that the production efficiency is low and the method is not suitable for mass production. The crimping connector has multiple types, and the fish eye contact pin of traditional crimping plug has longer direction part, has locating pin or guide pin assistance-localization real-time during the installation, inserts in the metallized hole of PCB through locating pin and guide pin, just can realize the location of plug and PCB, and each interior module is packed by metal or plastics casing, and the crimping mould can directly act on the casing and press into the contact pin. The high-speed high-density connector is different from the common packaging connector in that the hollow metal shell with special structure needs to avoid the metal frame to directly act on the high-speed plug module 34 in fig. 6 during crimping so as to avoid the damage of the connector. The automatic crimping machine is used for crimping an ultrahigh-speed high-density high-reliability connector, and the connector is not yet applied in China.
A quick positioning and crimping tool for VPX plugs is disclosed in China patent application CN202010891053.2, and is mainly used for solving the crimping problem of VPX series plugs and PCBs. Through the plug terminal surface to and plug both sides face is spacing, cooperates with the rectangle stand of installing in the lower mould locating plate again, realizes the locate function. The crimping mode is only suitable for screwless fixation, and can rely on pins and positioning pins to position the plug. The crimping cannot be performed on the ultra-high-speed high-density connector which is particularly short in pin type and is arranged at high density.
To realize the application of the reinforced ultra-high-speed high-density high-reliability connector on an automatic crimping machine, the structure, the positioning mode and the assembly method of the existing die are required to be improved.
