Description

TO-CAN single PIN tube with inclined window

Technical Field

The utility model relates TO a sensing device technical field especially relates TO a TO-CAN single PIN pipe with oblique window.

Background

The tube caps of the existing photodiode module (TO-CAN) are all spherical or flat windows, and the responsivity index and the return loss index of the chip are not ideal when the traditional structure is used, so that the requirement of a client needing higher responsivity index cannot be met.

Disclosure of Invention

The utility model provides an effectively improve the response, the TO-CAN single PIN pipe that has the skew window that return loss performance is better.

The utility model adopts the technical proposal that: a TO-CAN single PIN tube with a tilt window, comprising: the device comprises a tube seat, a tube shell, a chip and a plurality of pins; the lower end of the tube shell is arranged on the tube seat, the upper end of the tube shell is an inclined plane, the inclined plane is provided with an installation port, a coated glass window tube cap is installed in the installation port, and the included angle between the coated glass window tube cap and the top surface of the tube seat is 17 degrees;

the chip is obliquely arranged on the tube seat and is positioned in a space formed by enclosing the tube seat, the tube shell and the coated glass window tube cap, and the included angle between the chip and the top surface of the tube seat is 5 degrees; the pins are arranged on the tube seat and are in communication connection with the chip.

Furthermore, an inclined surface mounting groove is formed in the middle of the top surface of the tube seat, a ceramic carrier is mounted in the inclined surface mounting groove, and the chip is mounted on the ceramic carrier.

Further, the inclination direction of the inclined surface mounting groove is opposite to that of the inclined surface, so that the inclination direction of the chip is opposite to that of the coated glass window tube cap.

Compared with the prior art, the utility model discloses TO-CAN list PIN pipe with oblique window forms 5 angles through setting up the tube socket and chip, and coated glass window pipe cap forms 17 angles with the tube socket TO effectively guarantee the responsivity of list PIN pipe, make the return loss performance better.

Drawings

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention. In the drawings, there is shown in the drawings,

FIG. 1: the utility model discloses a three-dimensional view of a TO-CAN single PIN tube with an inclined window;

FIG. 2: the utility model discloses the cross-sectional view of TO-CAN single PIN pipe with oblique window.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

As shown in fig. 1 and 2, the TO-CAN single PIN tube with a tilted window of the present invention comprises a tube socket 1, a tube shell 2, a chip 3 and a plurality of PINs 4; wherein, the tube shell 2 is a cylinder with an opening at the lower end, and the upper end of the tube shell 2 is an inclined surface 8. The lower end opening of tube seat 1 encapsulation tube 2 is equipped with the installing port on the inclined plane 8, installs coating glass window pipe cap 5 in the installing port, plays the printing opacity, the effect of transmission signal. The chip 3 is arranged on the tube seat 1 and is positioned in a space formed by enclosing the tube seat 1, the tube shell 2 and the coated glass window tube cap 5. A plurality of pins 4 are mounted on the socket 1, and the plurality of pins 4 are in communication connection with the chip 3. In addition, the included angle between the coated glass window tube cap 5 and the top surface of the tube seat 1 is 17 degrees, so that the product has better return loss while ensuring the responsiveness.

The tube seat 1 is used for mounting a chip 3, and the protection window ensures air tightness and nitrogen gas filling protection; the tube shell 2 is used for bearing a coated glass window tube cap 5 and protecting the air tightness in the window; the chip 3 is used for receiving signals and converting optical signals into electric signals; the pins 4 are used for being soldered on a circuit board and transmitting electrical signals.

Further, tube socket 1's top surface intermediate position is equipped with inclined plane mounting groove 6, installs carrier 7 in inclined plane mounting groove 6, and chip 3 installs on carrier 7 for the contained angle of chip 3 and tube socket 1 top surface is 5 and is located tube socket 1's centre, makes the product when guaranteeing the responsivity, and the return loss is better. The inclined surface mounting groove 6 is inclined in the direction opposite to the inclined surface 8, so that the chip 3 is inclined in the direction opposite to the coated glass window cap 5. The carrier 7 is arranged to heighten the chip 3 and adjust the focal length.

TO sum up, the utility model has the advantages of TO-CAN single PIN pipe of oblique window has:

1. through setting up tube socket 1 and chip 3 and forming 5 angles, coated glass window pipe cap 5 forms 17 angles with tube socket 1 to effectively guarantee the responsivity of single PIN pipe, make the return loss performance better.

2. By centering the chip 3, the responsivity of the chip 3 is optimized.

3. By providing the carrier 7 on the stem 1, the chip 3 is provided on the carrier 7, thereby effectively controlling the focal length.

As long as the idea created by the present invention is not violated, various different embodiments of the present invention can be arbitrarily combined, and all the embodiments should be regarded as the content disclosed by the present invention; the utility model discloses an in the technical conception scope, carry out multiple simple variant and different embodiments to technical scheme and go on not violating the utility model discloses the arbitrary combination of the thought of creation all should be within the protection scope.
