Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of triode detection, in particular to a triode pin detection device. Background Art
[0002] The pin is one of the important components of the triode, which can effectively transmit current to the triode. The triode, whose full name should be semiconductor triode, also known as bipolar transistor and crystal triode, is a semiconductor device that controls current. Its function is to amplify weak signals into electrical signals with larger amplitude values. It is also used as a contactless switch.
[0003] At present, when testing the pins of transistors, a multimeter is usually used to measure between the three pins. However, this measurement method is easy to cause shaking when the hand shakes or is bumped because the transistor is not clamped. The shaking may cause the transistor to fall, and then the pins of the transistor may be bent. The measurement efficiency is relatively low, and the measurement difficulty is also large. The practicality is insufficient. The transistor cannot be clamped and positioned during the test, which easily causes the transistor to deviate, further reducing the measurement efficiency. In view of this, we propose a transistor pin detection device. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] (1) When testing the transistor pin detection device, the transistor is placed inside the transistor placement groove, and the pin is inserted into the pin placement groove. When the pin enters, the metal connection block is squeezed, so that the metal connection block moves. After the metal connection block moves, it drives the metal plate to move. When the placement is completed and the test is carried out, the sliding plate is unlocked by pulling the adjustment structure, and then the sliding plate drives the test plate to move. After the test plate moves, it contacts the metal plate, and then the pin is tested by the test device. Through the above structure, when testing, the transistor can be placed in the groove for testing, which protects the transistor and prevents the transistor from moving during the test.

[0014] (2) The transistor pin detection device uses the protection plate to compress the second spring when placing the transistor, giving the transistor a certain range of movement to prevent the transistor from being damaged by force. After the test is completed, the reset plate can be pulled, and the reset plate will simultaneously stretch the second reset spring. At the same time, the reset plate will also pull the triangular block synchronously. After the triangular block moves, the inclined surface contacts the ejector pin, and the ejector pin moves upward, thereby driving the protection plate to rise, thereby ejecting the transistor. The reset plate is then released and the second reset spring can be used to complete the reset. Through the above structure, not only can the staff complete the test of the transistor pins more easily and conveniently, but also when taking out the transistor, they can just pull the reset plate, which is convenient and will not cause damage to the transistor itself.
