Embodiment 1

[0023] Such as figure 1 As shown, a camera described in this embodiment can be extended with a shutter cable, including a cable release plug, a switch S1 and a switch S2, the switch S1 and the switch S2 are connected in parallel, the cable release plug is inserted into the corresponding socket of the camera, and the cable release is connected Entering the camera, the switch S1 and the switch S2 have the same switch function as the general shutter release, which can release the shutter and focus. On this basis, this embodiment also adds an expansion interface, which is connected in parallel to the two ends of the switch S1 On the terminal, through the expansion interface, the functional module can be connected to the shutter line, and can be connected with the camera, and the camera can realize the desired operation through the functional module. From figure 1 It can be seen from the figure that the expansion interface input terminal and the shutter line output terminal are in...

Embodiment 2

[0025] In this embodiment, on the basis of Embodiment 1, the expansion interface is limited to a USB interface. The first pin of the USB interface is the external power supply pin, the second pin is the internal battery charging pin, the third pin is the trigger signal pin, and the fourth pin is the external power supply pin. The pin is the public ground, and the USB interface is a common interface widely used at present. After the expansion interface is designed as a USB interface, it can be easily connected and the adaptability of the interface can be improved.

Embodiment 3

[0027] Such as figure 2 As shown, in this embodiment, on the basis of Embodiment 1, the functional module is limited to a lightning-triggered shutter module. The lightning-triggered shutter module includes a photosensitive resistor R1, a current limiting resistor R2, a potentiometer R3, and a triode T1. One end of the photosensitive resistor R1 Connect to the power supply VCC, the other end to one of the fixed contacts of the potentiometer R3, the movable contact of the potentiometer R3 is connected in series with the current limiting resistor R2 and then connected to the base of the triode T1, the emitter of the triode T1 is grounded, and the shutter module is triggered by lightning The output port is connected to the collector of the transistor T1, such as figure 2 As shown in the figure, the shutter line input + and the shutter line input - are the output ports of the lightning trigger shutter module, and the shutter line input + and the shutter line input - are the same ...

Abstract

The invention discloses an expandable cable release for a camera. The expandable cable release comprises a cable release plug, a switch S1 and a switch S2. The switch S1 and the switch S2 are in parallel connection. The expandable cable release further comprises an expansion port which is used for connecting a functional module to the cable release. The expansion port is parallelly connected to two ends of the switch S1. The functional module is a thunder and lightning triggering shutter module. The thunder and lightning triggering shutter module comprises a photosensitive resistor R1, a current limiting resistor R2, a potential R3 and triode T1, wherein one end of the photosensitive resistor R1 is connected with a power supply VCC, the other end of the photosensitive resistor R1 is connected with one of the fixed contacts of the potential R3, the movable contact of the potential R3 is serially connected to the current limiting resistor R2 and then connected to the base of the triode T1, and the emitter of the triode T1 is grounded. By the structure, the expandable cable release has the advantages that the camera, the cable release and the functional module are relatively independent, the requirements of shutterbugs can be fully satisfied, and repeat purchasing and resource waste can be avoided.

Description

technical field [0001] The invention relates to the field of shutter releases, in particular to an expandable shutter release for cameras. Background technique [0002] As a peripheral device of cameras, remote releases have been widely used. Ordinary remote releases can prevent camera shake. Some remote releases have the functions of preset time and long exposure, but these functions are inherent functions of remote releases and cannot be expanded at will. At present, there is no shutter release that can assist photographers to capture some unexpected events, such as lightning. Photographic equipment cannot meet the special requirements of photographers in special situations such as capturing emergencies, and photographers need a high degree of luck to capture wonderful pictures. Great economic and operational difficulties. Contents of the invention [0003] The purpose of the present invention is to provide an expandable remote release for cameras, which solves the pro...
