Abstract
The utility model discloses a output type coupler of a novel photosensitive thyristor, which comprises supports, the photosensitive thyristor and pins, wherein, the number of the pins is four; the four pins are oppositely arranged in a mode of two pins at one side; the upper parts of the pins bend inwards to form the supports; the photosensitive thyristor is fixed on one support. Because a photosensitive thyristor chip is arranged on one main terminal (support) and is stuck by an insulation adhesive, the output type coupler of the novel photosensitive thyristor achieves the aim of only using two pins. Compared with the output type coupler of an original photosensitive thyristor, two pins which are not used originally are subtracted, thereby the structure of the output type coupler of a novel photosensitive thyristor is simplified; moreover, because six pins are changed to be four pins, the size of the coupler can be made to be smaller so as to be more suitable for the development direction of miniaturizing the existing electronic devices.
Description
Technical field
The utility model relates to a kind of electronic device, particularly relates to a kind of novel photosensitive thyristor output type coupler.
Background technology
The optical coupler (shown in Figure 1A, Figure 1B, Fig. 1 C, Fig. 1 D) of existing photosensitive thyristor output type mainly is made up of support 1 ', photosensitive thyristor 2 ' and pin 3 ' both at home and abroad at present.From contour structures all is the encapsulating structure of employing standard six line DIP or SOP, that is: six pins 31 ', 32 ', 33 ', 34 ', 35 ', 36 ' (shown in Fig. 1 E) are arranged, its photosensitive thyristor chip 2 ' is to adopt elargol 4 ' to be bonded on the support 15 ' on middle pin 35 ' top, and size is 7.62mm * 6.4mm * 3.6mm.Along with the development of electric equipment miniaturization, the photosensitive thyristor output type optical coupler of this packaging appearance is bigger than normal on overall dimension, and pin is too much, more and more incompatible present electrical equipment developing direction.
The utility model content
The purpose of this utility model is to provide that a kind of volume is littler, the simple more novel photosensitive thyristor output type coupler of structure.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of novel photosensitive thyristor output type coupler, and it comprises support, photosensitive thyristor and pin; Described pin has four, these four pins are oppositely arranged in the mode on two on one side, pin top bends inwards and forms described support, described photosensitive thyristor is fixed therein on the support, and the support that is connected and fixed by two leads of photosensitive thyristor and with another root support of this support homonymy on.
Described photosensitive thyristor and support are packaged together.
After adopting such scheme, because the utility model is from the basis of the internal structure of the quick thyristor output type of original six linear lights optical coupler, the quick thyristor output type of the four linear lights optical coupler that design makes new advances, it is that photosensitive thyristor chip is placed on one of them main end (support), bond with insulating cement, thereby reach the purpose of only using two pins, photosensitive thyristor output type with six original lines is compared, reduced by two pins that do not have use originally, simplify the structure, and owing to change four pins into from six pins, it is littler that the volume of coupler can be done, its overall dimension is reduced into 4.5mm * 6.4mm * 3.6mm from the 7.62mm * 6.4mm * 3.6mm of original standard, thereby better adapts to the developing direction of present electronics miniaturization.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Embodiment
Shown in Fig. 2 A, Fig. 2 B, Fig. 2 C, Fig. 2 D, the utility model is a kind of novel quick thyristor output type of four linear lights coupler, and it comprises support 1, photosensitive thyristor 2, pin 3, diode 4.
Described pin 3 has four 31,32,33,34, these four pins 31,32,33,34 are divided into one group in twos, promptly, pin 31,32 is one group and is positioned at a side, pin 33,342 is positioned at opposite side for another group, these two groups of pins 31,32,33,34 are oppositely arranged, pin 31,32,33,34 tops bend inwards and form described support 11,12,13,14, described photosensitive thyristor 2 is fixed therein on the support 14, and photosensitive thyristor 2 by two leads 21,22 connect its fixing support 14 and with another root supports 13 of this support 14 homonymies on.
On another pack support 11,12 medium-height trestles 11 relative, diode 4 is installed with the support 14 that photosensitive thyristor 2 is installed, on the support 12 of this diode 4 by lead electrical connection and its homonymy, this makes diode 4 need relative with photosensitive thyristor 2 and establishes, thereby reaches the order that only uses two pins.
When assembling (shown in Fig. 2 E), the mode that described photosensitive thyristor chip 2 is fixed on the support 14 is with insulating cement 5 photosensitive thyristor chip 2 to be bonded on the support 14.
After assembling is finished, photosensitive thyristor 2, diode 4 are got up with support 11,12,13,14 encapsulation.
Emphasis of the present invention just is: change the structure of original six line DIP or SOP the structure of four line DIP or SOP into, two pins deletions will not using originally.
