Abstract
The present utility model discloses a connection edge socket. The connector comprises a shielding shell body, a PCB is arranged inside the shielding shell body, the PCB is provided with a filtering circuit and an electric pin array, and an axis of the electric pin array is parallel with an axis of the shielding shell body. As the PCB provided with the filtering circuit and the electric pin array is adopted to replace the prior plane ceramic capacitance array plate, the filtering circuit and the electric pin array are arranged on the PCB, the technology is simple, the structure is simple, and the PCB is low in costs. Moreover, the filtering connector is simple in structure and low in costs, and is very suitable to be applied to the civil or military field.
Description
Technical field
The utility model relates to a kind of electric connector, relates in particular to a kind of filter connector.
Background technology
In all kinds of electronic systems (particularly weaponry system), electric connector be usually used between device and device, between assembly and assembly or be electrically connected between system and system and connection device that signal transmits, be to consist of the necessary base components of holonomic system.And filter connector is the electric connector that possesses filter function, and it is to increase filter circuit construction (or being called filter network) improvement to form on the basis of general electric connector.Therefore, it had both possessed all functions of general electric connector, had again the characteristic that suppresses electromagnetic interference concurrently.At present filter connector is widely used in military service, particularly Aeronautics and Astronautics department.In recent years, along with the development of industrial production automation and popularizing of computer, computer and ancillary equipment thereof have used filter connector widely, and office equipment is also progressively using filter connector simultaneously.Yet, mostly adopting the manufacturing process of plane ceramic capacitor array plate due to present filter connector, its complex structure, cost are high, expensive, thereby have limited its application at civil area and general military equipment.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, filter connector that cost is low.
For achieving the above object, the utility model provides a kind of filter connector, comprises shield shell, in described shield shell, pcb board is installed, described pcb board is provided with filter circuit and electric mortiser pin array, and the axis of described electric mortiser pin array is parallel with the axis of described shield shell.
Filter connector of the present utility model adopts the pcb board which is provided with filter circuit and electric mortiser pin array to substitute existing plane ceramic capacitor array plate, because installation filter circuit and electric mortiser pin array processes on pcb board are simple, simple in structure, and pcb board is cheap, thereby filter connector of the present utility model is simple in structure, cost is low, is fit to very much the application of civilian or military domain.
Description of drawings
Fig. 1 is the structure cutaway view of filter connector of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:
With reference to shown in Figure 1, the filter connector of the present embodiment comprises shield shell 1, this shield shell 1 comprises columnar main casing 101 and additional housing 102, and an end of additional housing 102 is enclosed within on an end of main casing 101 and is connected cooperation with main casing 101 by ring flange.The inwall of additional housing 102 is provided with annular boss 102a, and a pcb board 2 is fixed on annular boss 102a by screw fit, and to reach the purpose of X2Y filter capacitor ground connection, the axis of additional housing 102 is perpendicular to the plate face of pcb board 2.Be provided with thermoset plastics insulator 101a in main casing 101, the plate face of thermoset plastics insulator 101a is parallel with the plate face of pcb board 2.Pcb board 2 is provided with filter circuit 3 and electric mortiser pin array 4.The axis of electric mortiser pin array 4 is parallel with the axis of shield shell 1, and an end of electric mortiser pin array 4 is fixed on pcb board 2 and is positioned at additional housing 102, and its other end passes thermoset plastics insulator 101a and gos deep in main casing 101.The electric capacity of filter circuit 3 adopts the X2Y capacitive filter, and each the electric mortiser pin in electric mortiser pin array 4 has the filtering over the ground of corresponding X2Y capacitive filter, thereby consists of C type filter circuit.Due to ESL(equivalent series inductance between the line of X2Y capacitive filter) 100pH only, line ground ESL is 50pH only, so the filter connector of the present embodiment has very high High frequency filter performance.In addition, because the X2Y capacitive filter is the electric capacity that a slice patch capacitor has two symmetrical balances, the X2Y capacitive filter that the pin number of the electric mortiser pin of the filter connector of the present embodiment only needs pin to count half gets final product, and need or not capacitive filter and electric mortiser pin quantity to be equal to, thereby dwindled the volume and weight of filter connector as existing filter connector.
In addition, for further improving filtering performance, filter circuit 3 can be promoted to LC filter circuit or π type filter circuit.This LC filter circuit can be to put a magnetic bead to consist of on each the electric mortiser pin after the plate face of pcb board 2.This π filter circuit can be to put magnetic bead on each the electric mortiser pin after the plate face of pcb board 2, consist of at second pcb board parallel with pcb board 2 of the additional interior installation of housing 102 again, and an end of the close pcb board 2 of electric mortiser pin array 4 passes from this second pcb board.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection range of claims of the present utility model.
