Abstract
The utility model discloses an anti-interference filtering connector, which comprises an insulation base with the upper part of which having a hole, wherein, a fixed mounting panel with a through hole is arranged on the insulation base, 60 filtering contact pins used for transmitting low frequency signals are arranged in the insulation base, the filtering contact pins are arranged in three rows and twenty lines, one end of the filtering contact pin passes through the through hole on the fixed mounting panel and is connected with a circumscribed low frequency line, while the other end passes through the hole on the insulation base and is positioned at the bottom of the insulation base to be taken as an earthing terminal; and on the 54 filtering contact pins in total which are counted from the second line to the line next to the last, a tubular cross-core ceramic capacitor is arranged. The anti-interference filtering connector of the utility model has reasonable structure design and convenient operation, and solves a technical problem that the interface of an electronic equipment is interfered by electromagnetism in the prior art, thus being a desirable connection device for the interface of the electronic equipment.
Description
Technical field
The utility model belongs to the electronic apparatus technical field, is specifically related to a kind of anti-interference filtration connector.
Background technology
At present, accurate day by day complexity of communication apparatus and multifunction, and various electronic equipments are subjected to electromagnetic interference and radio frequency interference all the time, with regard to a system, the interface of various electromagnetic interference is the most important, it can be worked in coordination with outside EMI conduction and be radiated internal system, the EMI of internal system can be conducted and be radiated the system outside again.Therefore, it is particularly important at interface anti-electromagnetic interference connector to be set.
Summary of the invention
The purpose of this utility model is to solve the technical problem that the prior art electronic equipment interfaces is subjected to electromagnetic interference, provides a kind of anti-interference filtration connector, to overcome the deficiencies in the prior art.
To achieve these goals, the utility model anti-interference filtration connector, it comprises the insulating base that top is with holes, insulating base is provided with the mounting plate of band through hole, be provided with 60 filtering contact pins that are used to transmit low frequency signal in the insulating base, the filtering contact pin becomes three rows, 20 row to arrange setting, and the through hole that an end of filtering contact pin passes on the mounting plate is connected with external low frequency line, and the other end places the bottom of insulating base as earth terminal by the hole on the insulating base; For guaranteeing that low frequency signal passes through smoothly, prevent radio frequency interference, walk to row second from the bottom second and be provided with tubulose punching ceramic capacitor on totally 54 filtering contact pins, form filtering unit.
For guaranteeing certain algorithm level, be provided with ground connection elasticity platelet between said mounting plate and the edge pedestal, the filtering contact pin of first row and last column welds with ground connection elasticity platelet respectively.
In order to make ground connection elasticity platelet and filtering contact pin and insulating base fixation, adopt casting glue to carry out embedding and solidify, make integral product firm stable, connection reliably.
The utility model reasonable in design, easy to use has solved the technical problem that the prior art electronic equipment interfaces is subjected to electromagnetic interference, is a kind of desirable electronic equipment interfaces connection device.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model filter circuit schematic diagram.
Embodiment
As shown in Figure 1, it comprises top insulating base with holes 4 the utility model, insulating base 4 is provided with the mounting plate 6 of band through hole, be provided with 60 filtering contact pins 5 that are used to transmit low frequency signal in the insulating base 4,5 one-tenth three rows of filtering contact pin, 20 row are arranged and are provided with, the through hole that one end of filtering contact pin 5 passes on the mounting plate is connected with external low frequency line, and the other end places the bottom of insulating base 4 as earth terminal 1 by the hole on the insulating base; Walk to row second from the bottom second and be provided with tubulose punching ceramic capacitor 2 on totally 54 filtering contact pins, form filtering unit; For guaranteeing certain algorithm level, the filtering contact pin that is provided with ground connection elasticity platelet 3, the first row and last column between said mounting plate and the edge pedestal welds with ground connection elasticity platelet respectively; In order to make ground connection elasticity platelet 3 and filtering contact pin 5 and insulating base 4 fixations, adopt casting glue to carry out embedding and solidify, make integral product firm stable, connection reliably.
The utility model employing shielding measure and filter circuit combine and suppress to disturb, and consider from jamproof angle, except that shielding measure, also have a grounded circuit problem, if screen imperfect earth also can influence shield effectiveness.So the design of grounding system is the subject matter of Anti-interference Design equally, when structural design, must attach great importance to.As shown in Figure 1 and Figure 2, the utility model filtering contact pin grounded circuit is to be connected with tubulose feed-through capacitor on the filtering contact pin by ground connection elasticity platelet, earth terminal 1 by the ground connection contact pin is fixed on the printed board common ground utmost point, forms ground networks with complete machine.In addition,, adopt public pole, be about to all filtering contact pin assemblies and all and between the ground connection elasticity platelet form contact matching in order to reduce potential difference.The aperture that arranged is arranged on ground connection elasticity platelet, the arrangement in hole is arranged identical with position, insulating base hole.For ground connection reliably and is better shunted, ground connection elasticity platelet is designed to elasticity multijaw form, be processed with promptly with insulating base on the position, hole arrange corresponding hole, all have the public pole that elastic claw blocks ceramic capacitor on each hole, the printed circuit board by ground connection contact pin and insulating base 4 bottoms joins.
