The present utility model will now be further described with reference to the accompanying drawings and embodiments:

[0024] Please see Figure 1-4 A limiting and bending type infrared receiver module includes an epoxy resin body 1, an internal shielding bracket 2, a receiver PD3, an integrated chip 4, and bending pins 5. The internal shielding bracket 2 includes a fixing part 6, a connecting part 7, and a shielding part 8. The fixing part 6 and the shielding part 8 are connected by the connecting part 7. The receiver PD3 and the integrated chip 4 are fixedly installed on the fixing part 6. The shielding part 8 is provided with a receiving window 9. The position of the receiving window 9 corresponds to the position of the receiver PD3. The top of the epoxy resin body 1 is provided with a convex mirror structure 10.

[0025] By employing a built-in shielding bracket 2, a PD receiver, and a convex mirror structure 10, the product achieves miniaturization, strong sealing, strong anti-interference, strong receiving signal, and good stability. Integrating the receiver PD3 and the integrated chip 4 together provides advantages such as small size and high sensitivity. By providing a convex mirror structure 10 on the top of the epoxy resin body 1, the external transmission signal is effectively improved, and the receiving line distance reaches 30m, thus giving the entire product strong anti-interference capability and high receiving signal strength.

[0026] Furthermore, the connecting part 7 is perpendicular to the fixing part 6, the connecting part 7 is perpendicular to the shielding part 8, and the shielding part 8 is parallel to the fixing part 6.

[0027] In the first embodiment of this utility model, the receiving window 9 of the shielding part 8 is D-shaped.

[0028] By setting up a D-shaped built-in shielding bracket 2, the product's anti-interference ability and signal reception capability are improved.

[0029] In the second embodiment of this utility model, the receiving window 9 of the shielding part 8 is provided with an X-mesh structure 11.

[0030] The X-net structure 11 is provided in the receiving window 9 of the shielding part 8, which improves the product's anti-interference ability and signal reception ability, effectively resists the interference of ambient light, further reduces the interference to the receiving PD3, and further improves the stability of the receiving infrared signal of the receiving PD3.

[0031] This utility model, by setting up an epoxy resin body 1, an internal shielding bracket 2, a receiver PD 3, an integrated chip 4, and bent pins 5, can receive signals emitted by an infrared emitting tube. After signal amplification, frequency selection, and modulation, the original signal is output to achieve the reception of 940nm infrared signals, thereby simplifying the product circuit and improving the product's sensitivity and anti-interference.

[0032] In another embodiment of the present invention, the bent pin 5 includes a first pin 12, a second pin 13 and a third pin 14, and one end of the second pin 13 is electrically connected to the built-in shielding bracket 2.

[0033] Furthermore, one end of the first pin 12 and one end of the third pin 14 are electrically connected to the integrated chip 4, respectively.

[0034] Furthermore, the receiving PD3 is connected to the integrated chip 4 via a gold wire 18.

[0035] Furthermore, the built-in shielding bracket 2 is connected to the integrated chip 4 via a gold wire 18.

[0036] Furthermore, the first pin 12 and the third pin 14 are respectively connected to the integrated chip 4 via gold wire 18.

[0037] Furthermore, the fixing part 6, the connecting part 7, and the shielding part 8 are integrally punched and bent.

[0038] Furthermore, the other end of the first pin 12 is provided with a first bend 15, the other end of the second pin 13 is provided with a second bend 16, and the other end of the third pin 14 is provided with a third bend 17.

[0039] Furthermore, the distance between the shielding part 8 and the fixing part 6 is 1.5mm-0.2mm to 1.5mm+0.2mm.

[0040] When the built-in shielding bracket 2 punches and bends the fixing part 6, the connecting part 7 and the shielding part 8, the bending parts of the first pin 12, the second pin 13 and the third pin 14 are punched out, so that no poor soldering or tilting occurs after the product is automatically placed and reflowed.

[0041] Furthermore, the peak wavelength of the received PD3 is 850-940nm, which blocks interference signals of other wavelengths, and the received pulse width is 560±56us.

[0042] During production, an automated sheet-laying machine is used to place the support brackets to be molded, and the injection molding is automated; the finished products are automatically cut, tested, CCD inspected, and packaged.

[0043] This utility model discloses a limiting-bending type infrared receiver module, which is miniaturized and meets the requirements of high-temperature reflow soldering and automatic surface mount technology (SMT). The top limit of the product is controlled within 1.5 + 0.02 / - 0.2 mm. Therefore, this limiting-bending type infrared receiver module can realize the needs of automated production and automatic SMT, and is easy to promote and implement.

[0044] The main functions of this utility model are:

[0045] This invention achieves miniaturization, strong sealing, strong anti-interference, strong signal reception, and good stability by employing a built-in shielding bracket, PD receiver, and convex mirror structure. Integrating the receiving PD and integrated chip together results in a small size and high sensitivity. The convex mirror structure on the top of the epoxy resin body effectively enhances the external transmission signal, achieving a receiving line distance of up to 30m, thus giving the entire product strong anti-interference capabilities and high signal strength. The D-shaped built-in shielding bracket improves the anti-interference and signal reception capabilities of the infrared receiver. The X-grid structure in the receiving window of the shielding part further enhances the anti-interference and signal reception capabilities of the infrared receiver, effectively resisting interference from ambient light and further reducing interference to the receiving PD, thereby improving the stability of the receiving PD's infrared signal reception.
