The module also has a circuit board on which an electronic device for controlling the light-emitting device is mounted, whereas the circuit board is mounted in a board mounting part of a lead frame. The circuit board is provided with a first pad to which a predetermined potential is applied, and a second pad for supplying a source voltage, whereas wires bonding the connection pin to the first and second pads respectively.
What is claimed is: 1. A transmission optical module comprising:
a light-emitting device assembly having a light-emitting device, a case for accommodating said light-emitting device, and a connection pin extending outward from said case and electrically connected to an anode of said light-emitting device; a circuit board, on which an electronic device for controlling said light-emitting device is mounted, and having a first pad to which a predetermined potential is applied and a second pad for supplying a source voltage; a lead frame having a board mounting part for mounting said circuit board; and wires bonding said connection pin to said first pad and second pads respectively. 2. A transmission optical module according to claim 1, wherein said source voltage is supplied to said light-emitting device from said second pad alone.
SUMMARY OF THE INVENTION The waveform of signal light outputted from the above-mentioned conventional transmission optical module, however, has not fully been stable. Therefore, it is an object of the present invention to provide a transmission module which can stabilize the waveform of signal light outputted therefrom.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view showing the overall structure of a transmission optical module in accordance with the present invention, whereas FIG. 2 is an exploded perspective view showing the inner structure thereof;
DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, a preferred embodiment of the transmission optical module in accordance with the present invention will be explained with reference to the accompanying drawings. To facilitate the comprehension of the explanation, the same reference numerals denote the same parts, where possible, throughout the drawings, and a repeated explanation will be omitted.
The island 24, first lead array 16, second lead array 30, and support part 26 constituting the lead frame 40 are disposed on a reference plane including the island 24. The first lead array 16 is constituted by ten lead pins, and is connected to a mount board, which is not depicted, thus making it possible to transmit electric signals between the optical module body 12 and the outside. On the other hand, the second lead array 30 is constituted by eight lead pins, and is connected to the external board 14, thus making it possible to transmit electric signals between the optical module body 12 and the external board 14. The first lead array 16 extends along the reference plane including the island 24, whereas the second lead array 30 has a base part 30 a extending along the reference plane and a bent part 30 b bent at a predetermined angle with respect to the base part 30 a. As shown in FIG. 2, the lead frame 40 has the support part 26, separated from the island 24, for supporting the holding member 50, and an auxiliary part 27 for assisting in supporting the holding member 50. The auxiliary part 27 is constituted by a frame-like member having one end connected to the support part 26. The support part 26 and auxiliary part 27 are disposed on the reference plane including the island 24, as with the other members constituting the lead frame 40.
