Description

Diode detector

Technical Field

The utility model relates to a diode detector belongs to electron detection facility field, in particular to simple and easy detection facility of diode.

Background

A diode, an electron tube having positive and negative poles, generally performs a rectifying function in a circuit. The diodes need to be tested before being mounted on the circuit board to ensure the safety and reliability of the circuit board, which otherwise would result in the failure of the circuit board to be used normally. When the existing power supply manufacturers detect the diodes, part of the manufacturers use full-automatic resistance value testing machines, and because the full-automatic resistance value testing machines are high in price and slow in cost recovery, part of the manufacturers use universal meters for testing. Because the universal meter can be tested only after the universal meter is in contact with the two ends of the diode through the meter pen, the speed of the test process is low, and the use cost of workers is increased. Therefore, a diode tester with low price and high testing speed is needed to replace the existing multimeter.

Disclosure of Invention

The utility model relates to a diode detector has solved above-mentioned difficulty, adopt rectangular casing, rectangular display screen is installed to the top in front of the casing, at the circular shape adjust knob of mid-mounting and rectangular switch, two semicircular contact pieces have been installed side by side perpendicularly in the preceding below of casing, rectangular circuit board has been installed to the internally mounted of casing, rectangular power and detection module have been installed on the circuit board, after the detector circular telegram, the workman uses special clip to press from both sides the middle part of diode and puts the electrode at diode both ends on two contact pieces, detection module reads out the rectification data of diode fast, it can inform bee calling organ to detect qualified diode detection module and send the call, if detect unqualified person and do not send the call.

A diode detector is characterized by comprising a casing, a power switch, a display screen, a contact piece, an adjusting knob, a power line, a circuit board, a power supply, a detection module and a buzzer;

the shell is a hollow rectangle made of plastic, a rectangular display screen is arranged above the front of the shell, a round adjusting knob is arranged on the left side of the middle part of the front of the shell, a rectangular power switch is arranged on the right side of the middle part of the front of the shell, and two semicircular copper contact pieces are vertically arranged on two sides of the center of the lower part of the front of the shell;

the circuit board is rectangular and is arranged in the shell, and a rectangular power supply and detection module is arranged on the circuit board;

the power switch is connected with the plug and the detection module through power lines respectively, and the detection module is connected with the display screen, the two contact pieces, the adjusting knob and the buzzer through the power lines respectively.

Has the advantages that: when the existing power supply manufacturers detect the diodes, part of the manufacturers use full-automatic resistance value testing machines, and because the full-automatic resistance value testing machines are high in price and slow in cost recovery, part of the manufacturers use universal meters for testing. Because the universal meter can be tested only after the universal meter is in contact with the two ends of the diode through the meter pen, the speed of the test process is low, and the use cost of workers is increased. A diode detector is characterized in that after the detector is electrified, a worker uses a special clamp to clamp the middle of a diode, electrodes at two ends of the diode are placed on two contact pieces, a detection module quickly reads rectification data of the diode, the diode detection module which is qualified in detection can inform a buzzer to send a call, and if the detection is not qualified, the buzzer does not send the call.

Detailed Description

The shape and structure of the present invention will be described in detail with reference to the accompanying drawings and the reference numerals:

a diode detector is characterized by comprising a machine shell 1, a power switch (DC12V/20A)2, a display screen (DC12V/1A)3, a contact piece (DC12V/10A)4, an adjusting knob (DC12V/1A)5, a power line 6, a circuit board 7, a power supply (AC220V/DC12V/20A)8, a detection module (DC12V/20A)9 and a buzzer (DC12V/1A) 10;

the portable electronic device is characterized in that the casing 1 is a hollow rectangle made of plastic, a rectangular display screen 3 is arranged above the front of the casing 1, a round adjusting knob 5 is arranged on the left side of the middle part of the front of the casing 1, a rectangular power switch 2 is arranged on the right side of the front of the casing 1, and a semicircular copper contact piece 4 is vertically arranged on each of two sides of the center of the lower part of the front of the casing 1;

the circuit board 7 is rectangular and is arranged in the shell 1, and a rectangular power supply 8 and a detection module 9 are arranged on the circuit board 7;

the power switch 2 is connected with the plug and the detection module 9 through the power line 6 respectively, and the detection module 9 is connected with the display screen 3, the two contact pieces 4, the adjusting knob 5 and the buzzer 10 through the power line 6 respectively.

When the diode detector is used, a worker inserts a power socket, turns on a power switch, rotates an adjusting knob to a corresponding gear according to the data range of a diode to be detected by the worker, displays the highest value and the lowest value of the data of the detected range on a display screen, uses a special clamp to clamp the middle part of the diode, places electrodes at two ends of the diode on two contact pieces, a detection module quickly reads the rectification data of the diode through the data transmitted by the contact pieces (if the data transmitted by the contact pieces is reverse, the detection module automatically and quickly changes the directions of the anode and the cathode), the detection module informs a buzzer to give a call when the detection data of the diode is in the range of a set value, the diode is indicated to be qualified, the worker discards the diode into a qualified product turnover box, and if the detection data of the diode is not in the range of the set value, the, And indicating that the diode is an unqualified product, throwing the diode into an unqualified product turnover box by a worker, and continuously detecting the diode by the worker according to the operation method.
