Embodiment
See also Fig. 2, Fig. 3 and Fig. 4, Figure 2 shows that vertical view according to coupling arrangement of the present invention, Figure 3 shows that diagrammatic cross-section, the partial structurtes synoptic diagram after Figure 4 shows that coupling arrangement according to the present invention and first connector combining according to coupling arrangement of the present invention.The invention provides a kind of coupling arrangement 10, be suitable for the electronic installation (not shown) is tested.Electronic installation has plug-type first connector 20 and cooperates electrical connection with coupling arrangement 10.In the present embodiment, electronic installation for example is a liquid crystal indicator.Coupling arrangement 10 comprises the printed circuit board (PCB) 11 and first port one 2.Wherein first port one 2 is suitable for being connected to reach electric coupling with first connector 20.Printed circuit board (PCB) 11 has first surface 111 and the second surface 112 that is oppositely arranged, and the end of first surface 111 has the 3rd surface 113 that relative first surface 111 indents are provided with.That is the plane on the 3rd surface 113 is lower than the plane of first surface 111.First port one 2 has a plurality of terminals 13, and the signal that these terminals 13 are convexly set in the 3rd surface 113 in parallel to each other and connect outside wire rod 14 is to carry out the transmission of signal.External signal for example is the test signal of liquid crystal indicator.
Wherein printed circuit board (PCB) 11 is a multilayer circuit board, and has internal layer circuit 15, and internal layer circuit 15 electrically connects these terminals 13 and wire rod 14.
These terminals 13 of first port one 2 are equivalent to golden finger, and it can be pegged graft with plug-in type first connector 20 of liquid crystal indicator (product) and cooperate.When 10 pairs of liquid crystal indicators of coupling arrangement are tested, these terminals 13 are inserted first connector 20, the coupling arrangement 10 and first connector 20 are electrically connected, the signal of wire rod 15 can be passed to liquid crystal indicator by these terminals 13 and first connector 20, so that liquid crystal indicator is tested.Wherein the length of terminal 13 can guarantee termination contact and electric connection in the terminal 13 and first connector 20 like this smaller or equal to the degree of depth of coupling arrangement 10 insertions first connector 20.
And, for present embodiment,, can be directly the front end of these terminals 13 be cut a little and can continue to use coupling arrangement 10 to test when the terminal 13 grafting increased frequency of first port one 2 and when damaged condition occurring.
See also Fig. 5, Figure 5 shows that rear view according to coupling arrangement of the present invention.In addition, coupling arrangement 10 also comprises joint 16, and joint 16 connects the internal layer circuit 15 and the wire rod 14 of printed circuit board (PCB) 11.And joint 16 comprises a plurality of stitch 17, and these stitch 17 are electrically connected wire rods 14, and the signal of wire rod 14 reaches a plurality of terminals 13 of first port one 2 of coupling arrangement 10 via these stitch 17, internal layer circuit 15.The second surface 112 that these stitch 17 can be parallel to printed circuit board (PCB) 11 is provided with, promptly as shown in Figure 5.Certainly, these stitch 17 also can be provided with perpendicular to the second surface 112 of printed circuit board (PCB) 11, are electrically connected to these stitch 17 promptly with the perpendicular direction setting of these stitch 17 as shown in Figure 5, and then with wire rod 14.
In addition, coupling arrangement 10 also comprises housing 18, and housing 18 is based in the end of second surface 112, in order to ccontaining arrangement wire rod 14, wire rod 14 is stretched out from housing 18 ends.More specifically, housing 18 can cover the top of joint 16, with protection joint 16, and guarantees the effect that engages between wire rod 14 and the internal layer circuit 15.That is behind the covering upper shell, can prevent that jointing 16 places of wire rod 14 and internal layer circuit 15 from touching or pullling with extraneous, damage or the bad situation of joint effect appear.Understandable, the housing 18 and first port one 2 are divided into the two ends of printed circuit board (PCB) 11.
For housing 18 is firmly engaged with printed circuit board (PCB) 11, and be beneficial to dismounting, changing internal wiring, for example can be between housing 18 and the printed circuit board (PCB) 11 or pass through the mode combination of welding by the mode combination that engage.More specifically, the lateral margin of housing 18 can have the holding section, and this holding section for example is a trip.Printed circuit board (PCB) 11 can have another holding section on corresponding to the position of holding section, for example be draw-in groove, to match with grab, housing 18 and printed circuit board (PCB) 11 is firmly combined, and be easy to dismounting.Yet not as restriction, be principle in other embodiments, combining closely.
