Abstract

The invention provides a keyboard tin connection test fixture and is applied to a keyboard cable tin connection test. One end of a keyboard cable is provided with a cable connector, and the cable connector is provided with odd-numbered terminal interfaces and even-numbered terminal interfaces. The keyboard tin connection test fixture comprises a plurality of first leads, wherein each first lead is connected with the odd-numbered terminal interfaces, and the other end of each first lead converges at a first contact; a plurality of second leads, wherein each second lead is connected with the even-numbered terminal interfaces, and the other end of each second lead converges at a second contact; a DC source which has one end connected with the first contact and the other end connected with the second contact; and a sounding unit connected in series between the DC source and the first contact or the second contact. According to the invention, the structure is simple, management and control are easy, whether tin connection is generated in the keyboard cable can be tested at ease, and the product quality is guaranteed.

Description

【Technical field】 [0001] The invention relates to a fixture for testing a keyboard, in particular to a fixture for testing a keyboard with tin. 【Background technique】 [0002] Nowadays, computers are more and more widely used in people's lives, so people's requirements for computer quality are getting higher and higher. However, when producing computer keyboards in the factory, due to the denser keyboard cables, it is easy to cause soldering during soldering, and the defect rate is high. Inspection or magnifying glass inspection, etc. However, this inspection method is time-consuming and laborious, and it will still cause too many defective products to flow out. [0003] In view of this, it is really necessary to provide a test fixture to solve the above-mentioned problem of difficulty in testing the connection of the keyboard cable with tin, resulting in the outflow of defective products. 【Content of invention】 [0004] In order to achieve the above purpose, the present...
