However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0016] The following combination Figs. 1 to 3 The technical solution of the present invention will be further described as follows:

[0017] The high-security interface device includes: a housing, with a first interface area formed on the front of the housing. Multiple sets of P-TAP female connector assemblies are longitudinally distributed within the first interface area. Each set of P-TAP female connector assemblies includes a P-TAP female connector with a mechanical switch and an indicator light for indicating the working status of the P-TAP female connector. In this embodiment, four P-TAP female connectors are used as an example. The specific number can be limited according to design requirements; the number of P-TAP female connectors is not limited here. Fig. 1 and Fig. 2As shown, the interface device includes: 2-core LEMO female socket 101 and 4-core Hirose female socket 102 compatible design; USB A and USB C female socket compatible design (USBA female socket 103 in the figure); 4 P-TAP female sockets 104, 106, 108, 110 with mechanical switches to meet the user's interface quantity demand; 4 blue LED indicator lights (105, 107, 109, 111) for indicating the working status of 4 P-TAP female sockets 104, 106, 108 and 110 respectively, LED blue long light represents P-TAP socket working normal, LED off represents P-TAP socket working abnormally, no output; Intelligent P-TAP plug 114, which can not only obtain power from the battery end, but also read battery information (the battery end needs to be equipped with intelligent P-TAP female socket); 1 three-color LED indicator light 112 for indicating the input interface state of P-TAP plug 114 (LED green light long light represents normal input; LED red light flickering represents insufficient battery power of input battery, red light always on represents input battery undervoltage, needs to replace the battery, at this time PT-4SBP has no input; LED yellow light flickering represents that the input current exceeds the protection current, PT-4SBP has no output; LED off represents no input or input positive and negative poles are connected reversely, PT-4SBP has no output); Fixing member: standard 15mm pipe clamp 113, used for fixing PT-4SBP in one way; Fixing member: 15mm groove 115, used for clamping standard R15 pipe, which can be fixed with PT-4SBP in cooperation with slot hole 116.

[0018] The main control circuit inside the shell is as shown in Fig. 3As shown, by detecting whether the P-TAP / smart P-TAP plug 114 input is reversed, the off of the MOS Q1 and Q2 realizes the purpose of polarity reversal protection; by SMB communication and resistance voltage divider detecting battery capacity and voltage, the off of the MOS Q3 realizes the purpose of under-voltage protection, preventing deep discharge of the battery; by Isense resistance and LMV33 sampling loop current, the off of the MOS Q3 realizes the purpose of overcurrent protection and short circuit protection; the MCU controls the input indicator light color and lighting mode by reading and collecting battery information, under-voltage protection signal, overcurrent protection signal, etc., so that the user can intuitively obtain relevant information; when the input loop function is normal, the MOS Q1, Q2 and Q3 are turned on, the 2-core LEMO, 4-core Hirose, USB A and USB C female seats supply power normally, and the 4 P-TAP female seat inputs supply power normally; the MCU judges whether there is a P-TAP plug connected by collecting mechanical switch 1, mechanical switch 2, mechanical switch 3 and mechanical switch 4 signals; when a P-TAP plug is connected, the MCU controls MOS Q4, Q5, Q6 and Q7 (field effect tubes) to realize the purpose of negative electrode first connected and positive electrode delayed connected; because the impedance of the power supply line is much lower than that of the signal line shielding layer, the positive and negative electrodes form a large current loop, and the large current loop no longer passes through the signal line, so as to achieve the purpose of protecting the camera device interface (such as SDI interface) from being damaged. At the same time, the 4 P-TAP indicator lights correspond to the working states of the 4 P-TAP female seats respectively, so that the user can intuitively obtain the working state information of the P-TAP female seat.
