Description
The utility model relates in particular to the grounding construction of this circuit board about a kind of circuit board that is used for the clamp connected connector.
The electric connector that is connected with printed circuit board (PCB) in the clamping connection mode exists for a long time, bayonet connector promptly is a kind of of clamp connected connector, for example can be an example (MICTOR is one of the trade mark of the AMP Science and Technology Ltd. of the above-mentioned Delaware State) from the matched impedance type connectors such as MICTOR connector that the AMP Science and Technology Ltd. of Delaware, USA buys.Be the U.S. the 5th as depicted in figs. 1 and 2,199, the schematic diagram of the matched impedance type connector that No. 885 patent disclosed, this connector includes two row's conducting terminals 10, be formed with the space of accommodating circuit board 12 two rows between the terminals, the set conducting strip 14 in these conducting terminals 10 and circuit board 12 surfaces contacts and in 12 formation electric connections of this connector 10 and circuit board.Described circuit board 12 upper edges are contained in a lateral margin 18 in aforementioned conducting terminal 10 spaces near it and the position of the suitable distance of being separated by is provided with some through holes 16, and each through hole 16 is provided with the inside coating of the grounding path that is electrically connected to circuit board 12.This connector further is provided with some earth terminals 20, and it is arranged in the space between the aforementioned conducting terminal 10, enters in the corresponding through hole 16 with the lateral margin 18 that passes described circuit board 12, is connected and reach with the grounding path of circuit board 12.
In above-mentioned the ' No. 885 patents, mentioned once that several guaranteed the mode that correctly is connected between the interior coating of earth terminal 20 and through hole 16, yet described mode both had been not suitable for practical situation, also need to set up additional structure and can cause structure complicated.
Between the interior coating of described earth terminal 20 and through hole 16 feasible pattern of construction electrical connection path be provided with some from circuit board 12 lateral margins 18 to the slit that corresponding through hole 16 extends, make earth terminal 20 to extend in the described through hole 16 by these slits.These slits are processed to form by particular tool when connector is assembled to circuit board 12, that is, these slits are just machine-shaping after the interior coating of through hole 16 is finished, thereby the result of this machine-shaping process, must cause the damage that is difficult to remedy to the interior coating of through hole 16, and can't guarantee that correct between described earth terminal 20 and coating, excellent electrical property is connected.
And, each earth terminal 20 all is to contact with the interior coating of corresponding through hole 16 by its tip, only form a some contact relation between the two, so in the connector operation, be difficult to keep the continuation and the continuity that electrically contact between this earth terminal and coating.
Therefore, be necessary to provide a kind of connector construction that is used for the clamp connected connector, it had firmly, reliably the ground connection performance to be to overcome the shortcoming of above-mentioned existing structure.
The purpose of this utility model is to provide a kind of circuit board that is connected with group with bayonet connector of using, and can guarantee to continue between itself and the bayonet connector, link up and good ground connection conductive path.
For achieving the above object, this circuit board includes the basic unit of tool first surface and second surface, respectively is laid with signal line and ground path on first and second surface.This basic unit includes a lateral margin, first and second surface at this lateral margin place simultaneously with a connector winding together.It is characterized in that, be provided with some through holes and slit near the position of the suitable distance of described lateral margin in this basic unit, and these slits are interconnected and extend to above-mentioned lateral margin with corresponding through hole and sentence the earth terminal of guiding and holding connector.Inner surface at above-mentioned through hole and slit is provided with first and second conductive layer that links to each other with the grounding path of this circuit board, and can electrically connect with corresponding earth terminal.Above-mentioned slit has and earth terminal size corresponding width, make earth terminal can be simultaneously with slit in both side surface keep in touch, thereby guarantee firm between earth terminal and conductive layer, electrically connect reliably.
In addition, above-mentioned conductive layer is provided with along the circumference of each through hole and corresponding slit inner surface, and, at the lateral margin of circuit board third and fourth conductive layer is set further also.Because this conductive layer just is provided with after slit on the circuit board is made moulding, thereby its forming process can not cause the damage of conductive layer.
Compared with prior art, the ground connection performance that the utility model can be guaranteed to continue, link up, and simplify processing procedure relatively, reduce manufacturing cost.
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.

Fig. 2 is the plane exploded view of existing matched impedance connector.
Fig. 3 is the partial perspective view of the utility model clamp connected connector with circuit board.
Fig. 4 is the plane graph of circuit board shown in Figure 3.
See also shown in Figure 3, the utility model circuit board 100 includes the basic unit 102 on first and second surface 134,136 of tool, and respectively be provided with the conducting wire that comprises signal line 104 and ground path 106 on this two surface 134,136, this basic unit 102 has a lateral margin 108 that is connected between first and second surface 134,136, make a connector especially a bayonet connector directly winding on this position, as described in preamble " DESCRIPTION OF THE PRIOR ART ", and the conducting terminal of connector and signal line 104 are conducted.
Position in these basic unit 102 upper edges near described lateral margin 108 suitable distances is provided with some through holes 110, pegs graft for the earth terminal of bayonet connector.Be provided with some slits 112 from each through hole 110 towards the extension of lateral margin 108 directions in this basic unit 102, these slits 112 have opening 114 near lateral margin 108 1 ends, and can accommodate the corresponding earth terminal of bayonet connector.
In the inner surface of described each through hole 110 conductive layer (calling first conductive layer in the following text) that metal level 116 or other electric conducting materials form is set, and the conducting that is connected with the ground path 106 of circuit board 110 of this first conductive layer 116.And, on the two side walls of each slit 112, also be provided with metal level 118 (calling second conductive layer in the following text), these first and second conductive layers 116,118 are connected to one and form through hole 110 and slit 112 interior continuous conductive surfaces, so when the earth terminal of bayonet connector inserts in the through holes 110 by slit 112, can formation electric connection between the ground path 106 of the earth terminal of this connector and circuit board 100 by means of this first and second conductive layer.And, slit 112 have with earth terminal (shown in Fig. 4 dotted line, label not) cross sectional dimensions corresponding width, make earth terminal can be simultaneously with slit in both side surface keep being close to contacting, and between second conductive layer 118 of slit 112 and earth terminal, form a face contact relation.Whereby, can guarantee that mechanicalness stable between the earth terminal of this circuit board 100 and connector cooperates, and guarantee firm between earth terminal and the conductive layer 106, electrically connect reliably.
