Abstract
The utility model relates to a filter circuit board for a connecting device. The filter circuit board comprises a circuit board body, wherein , a plurality of filtering elements are welded on the circuit board body, and COB bonder covers the circuit board body except for the filtering element welding points. Compared with the prior art, the COB Bonder covers the circuit board body except for the filtering element welding points, so that instant high temperature caused by welding or temperature impacting is avoided, the damage of the filtering elements on the circuit board body caused by the physical force generated by the bending of the flexible circuit board is eliminated, and the reliability is improved.
Description
Technical field
The utility model relates to a kind of filter circuit plate that is used for connector.
Background technology
Along with socioeconomic continuous development, various communication apparatus become increasingly complex and precise treatment, and various electronic equipments are subjected to the puzzlement of electromagnetic interference (EMI) all the time, particularly the interface of various electromagnetic interference is the most key, it both can conduct the electromagnetic interference of outside and be radiated internal system, can and be radiated the system outside with the conduction of the electromagnetic interference of internal system again, therefore, at the system interface place anti-electromagnetic interference connector is set and just seem very important.
At present the used anti-electromagnetic interference connector of electron trade normally is designed to one with filter element and connector, and filter element often needs special customization just can meet the requirements, and it is higher not only to process comparatively complexity and cost; And when the different needs of environment for use was selected the filter element of different size, this structure was not easy to change filter element.
A kind of filter connector is disclosed as Chinese patent CN2598204Y, by preceding, back iron-clad and be sleeved on before, before in the back iron-clad, back plastic cement body and a plurality of link are in formation, before described, also be provided with printed circuit board (PCB) in the back iron-clad, the centre of described printed circuit board (PCB) has the through hole of many row's tape welding dishes, described splicing ear passes from through hole respectively, and weld together with through hole, the other electric capacity that is provided with one to one of through hole, one end of described electric capacity welds together by connection lead and the splicing ear on the printed circuit board (PCB), and its other end all is welded on the common wire on the printed circuit board (PCB).
The electric capacity that is provided with on the printed circuit board (PCB) of above-mentioned filter connector is easy to break down under the situation of high temperature such as welding, causes condenser failure, so that influences the filtering performance of filter connector.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming of prior art, and a kind of filter circuit plate that is used for connector with high temperature protection is provided.
The utility model adopts following technical scheme:
A kind of filter circuit plate that is used for connector includes the circuit board body, is welded with some filter elements on this circuit board body, is coated with the COB bonder outside this filter element solder joint.
Outside described filter element integral body and solder joint thereof, all be coated with described COB bonder.
Described circuit board body is a flexible PCB.
By above-mentioned to description of the present utility model as can be known, compared with prior art, a kind of filter circuit plate that is used for connector of the present utility model has following beneficial effect:
At first, the utility model is coated with the COB bonder outside the filter element solder joint, can avoid when welding or temperature shock, producing moment high temperature effectively, can eliminate simultaneously because the crooked physical force that produces of flexible PCB to the damage that the filter element on the circuit board body causes, has improved reliability;
Secondly, the circuit board body is a flexible PCB, can effectively reduce small product size, increases the convenience that carries; Can reduce the weight of final products; Can improve pliability, strengthen in the confined space, doing tridimensional assembling.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below the utility model will be further described by embodiment.
With reference to Fig. 1, a kind of filter circuit plate that is used for connector of the present utility model, include flexible PCB body 10, on flexible PCB body 10, be welded with a plurality of filter elements 20, outside filter element 20 integral body and solder joint 30 thereof, all be coated with COB bonder 40.
Above-mentioned only is an embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection range.
