Description

Technical Field

[0001] This utility model relates to the field of diode processing technology, specifically to a diode testing device. Background Technology

[0002] A light-emitting diode (LED) is a type of semiconductor diode that converts electrical energy into light energy. Like ordinary diodes, an LED consists of a PN junction and exhibits unidirectional conductivity. When a forward voltage is applied to an LED, holes injected from the P-region into the N-region and electrons injected from the N-region into the P-region recombine with electrons in the N-region and holes in the P-region within a few micrometers of the PN junction, producing spontaneous emission of fluorescence. The energy states of electrons and holes differ in different semiconductor materials. The amount of energy released when electrons and holes recombine varies; the more energy released, the shorter the wavelength of the emitted light. Commonly used LEDs emit red, green, or yellow light.

[0003] After LEDs are manufactured, they typically undergo conformity testing. Common testing methods generally involve three steps: First, determine the positive and negative terminals of the LED. For LEDs with unequal pin lengths, the longer pin is generally positive and the shorter pin is negative. Second, energize both pins of the LED and check if it emits light. Third, reverse the polarity of the power supply, reconnect the pins, and test again. However, in actual testing, it has been found that traditional testing probes typically require two hands, necessitating simultaneous operation, which is inconvenient. Therefore, we provide a testing device that can be operated with one hand. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a diode detection device that solves the problem of inconvenient two-handed operation for detection mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a diode detection device, comprising a handle one and a handle two, which are rotatably connected. A detection conductor is provided at the front end of both handle one and handle two. A switch is provided on the inner wall of handle one. An ammeter is connected to the rear end of handle one. A battery is provided on the inner wall of handle two. A wire assembly is connected to the rear end of handle two via a nut. The detection conductor, wire assembly, ammeter, and switch are electrically connected.

[0006] Optionally, both handle one and handle two are provided with a gripping part on their side walls. The side walls of the gripping part are arc-shaped and have multiple equidistant anti-slip grooves. The anti-slip grooves can improve friction and make it convenient for people to grip handle one and handle two.

[0007] Optionally, the bottom of the first handle has a connecting part, and the top of the second handle has two connecting parts. The first handle and the second handle are rotatably connected by a pin passing through the center of the connecting part. The spacing between the rotatably connected first handle and second handle can be adjusted to accommodate diode detection with different spacing.

[0008] Optionally, a support spring is fixedly connected to the top of the second handle, and a slot adapted to the support spring is opened at the bottom of the first handle. One end of the support spring is inserted into the slot to provide elastic potential energy for the first and second handles to separate outward. The advantage of using a support spring is that it provides support force, which makes it convenient for the first and second handles to automatically contact the diode pin to be detected.

[0009] Optionally, the detection conductor includes an extension section and a bending section. The bending section is bent inward at an inward arc and is made of an elastic conductive metal material. Specifically, the bending section uses a soft steel hollow tube with a conductive copper strip inserted through its center.

[0010] Optionally, the switch includes a base fixedly connected to an inner wall of the handle, a button rotatably connected to the inner wall of the base, a movable conductive spring provided on the inner wall of the base, a spring abutment pin provided in the middle of the inner bottom wall of the base, and a fixed conductive structure provided on one side of the inner bottom wall of the base. The button can be swung to abut the movable conductive spring to contact the fixed conductive structure to form an electrical connection. The battery can be switched on and off by adjusting the position of the button.

[0011] Optionally, the lead assembly includes a flexible lead wire electrically connected to the ammeter. One end of the flexible lead wire, which passes through the nut, is connected to a conductive plate. The conductive plate can be electrically connected to the battery. The flexible lead wire can be adjusted to ensure continuous power supply when the first handle and the second handle are in motion.

[0012] Optionally, the nut has a through hole in the middle for the soft wire to pass through. The nut and the handle are connected by two threads to contact the conductive plate and connect it to the battery. The nut facilitates the removal of the battery, and the battery is a rechargeable battery that can be recycled.

[0013] This invention provides a diode detection device, which has the following advantages:

[0014] This diode testing device consists of a handle, a second handle, a testing conductor, an ammeter, a switch, a nut, a battery, and a wire assembly. The first and second handles are rotatably connected, allowing the user to hold both handles simultaneously with one hand. By compressing the gap between the two handles, the testing conductor is inserted between the two pins of the diode to make contact and perform testing. The bending section of the testing conductor ensures better contact with the pins, while its elasticity prevents excessive pressure from damaging them. During testing, the current can also be checked to ensure it is within the normal range, thus further determining the diode's performance. The wire assembly is connected to the second handle via a nut, facilitating battery replacement and charging. Attached Figure Description

Detailed Implementation

[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a diode detection device, including a handle 1 and a handle 2, which are rotatably connected. The front end of both handle 1 and handle 2 is provided with a detection conductor 3. The inner side wall of handle 1 is provided with a switch 4. The rear end of handle 1 is connected to an ammeter 5. The inner side wall of handle 2 is provided with a battery 6. The rear end of handle 2 is connected to a wire assembly 8 through a nut 7. The detection conductor 3, the wire assembly 8, the ammeter 5 and the switch 4 are electrically connected.

[0025] As a preferred embodiment, based on the above method, both handle 1 and handle 2 are further provided with a gripping part 9 on their side walls. The side walls of the gripping part 9 are arc-shaped and have multiple equidistant anti-slip grooves. The anti-slip grooves can improve the friction and make it convenient for people to grip handle 1 and handle 2.

[0026] The bottom of handle 1 has a connecting part, and the top of handle 2 has two connecting parts. Handle 1 and handle 2 are rotatably connected by a pin 10 passing through the center of the connecting part. The rotatably connected handle 1 and handle 2 can be adjusted in distance, which is suitable for diode detection with different distances.

[0027] A support spring 11 is fixedly connected to the top of the handle 2. The bottom of the handle 1 has a slot that matches the support spring 11. One end of the support spring 11 is inserted into the slot to provide elastic potential energy for the handle 1 and handle 2 to separate outward. The advantage of using the support spring 11 is that it provides support force, which makes it easy for the handle 1 and handle 2 to automatically contact the diode pin to be detected.

[0028] The detection conductor 3 includes an extension section 31 and a bending section 32. The bending section 32 is bent inward at an arc. The bending section 32 is made of an elastic conductive metal material. Specifically, the bending section 32 uses a soft steel hollow tube with a conductive copper strip inserted into the center.

[0029] In a preferred embodiment, based on the above method, the switch 4 further includes a base 41 fixedly connected to the inner wall of the handle 1. A button 42 is rotatably connected to the inner wall of the base 41. A movable conductive spring 43 is provided on the inner wall of the base 41. A spring abutting pin 44 is provided in the middle of the inner bottom wall of the base 41. A fixed conductive structure 45 is provided on one side of the inner bottom wall of the base 41. When the button 42 swings, it can abut the movable conductive spring 43 and contact the fixed conductive structure 45 to form an electrical connection. The power supply to the battery 6 can be turned on and off by adjusting the position of the button 42.

[0030] The wire assembly 8 includes a flexible wire 81 that is electrically connected to the ammeter 5. One end of the flexible wire 81, which passes through the nut 7, is connected to a conductive piece 82. The conductive piece 82 can be electrically connected to the battery 6. The flexible wire 81 can be changed to ensure continuous power supply when the handle 1 and handle 2 are in motion.

[0031] The nut 7 has a through hole in the middle for the soft wire 81 to pass through. The nut 7 is threaded to the handle 2 and can contact the conductive plate 82 to electrically connect with the battery 6. The nut 7 makes it easy to remove the battery 6. The battery 6 is a rechargeable battery for recycling.

[0032] In summary, this diode testing device, during use, connects handle 1 and handle 2 via a pivot pin and is further supported by a support spring 11. The user can simultaneously hold both handles 1 and 2 with one hand, compressing the gap between them to insert the detection conductor 3 between the two leads of the diode for contact testing. The detection conductor 3, with its bent section 32, ensures better contact with the leads while its elasticity prevents excessive pressure and damage. During testing, it can also simultaneously check whether the current is within the normal range. The diode's performance is further determined by the surrounding structure. The wire assembly 8 is connected to the handle 2 via the nut 7, facilitating disassembly for battery 6 replacement and charging. Disassembly is performed by simply rotating the nut 7. Since the flexible wire 81 is inserted into the nut 7, it will not rotate when the nut 7 is rotated. When not in use, the button 42 can be pressed. The movement of the button 42 pushes the moving conductive spring 43 to abut against the fixed conductive structure 45, thereby achieving electrical connection. Conversely, pressing the button 42 in the opposite direction will cause the moving conductive spring 43 to automatically reset and disengage from the fixed conductive structure 45 after the pressure is released, thus disconnecting the power.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
