Description
Technical Field
The utility model relates to a no secondary lock connector's terminal location detection device.
Background
A connector, which is a device that connects two active devices, is used to transmit current or signals. After the connector is assembled, the terminal needs to be positioned and detected so as to ensure the accuracy and effectiveness of the terminal in subsequent connection and avoid the situation that the terminal cannot be connected due to non-positioning. Usually, the positioning detection needs to be performed one by one, and a plurality of terminals may be arranged in one connector, which is troublesome to detect.
The existing connectors are roughly divided into a secondary lock and a non-secondary lock according to the composition structure. The secondary locking connector is characterized in that the metal terminal is inserted into the insulating seat, and then the locking plate is additionally arranged on the insulating seat to carry out secondary locking. The connector 1 without secondary lock is to insert the metal terminal 11 directly onto the insulating base 13, and to hook the elastic hook 14 in the insulating base 13 into the positioning slot 12 of the metal terminal 11 to achieve fixing without adding a locking structure, and at this time, a gap D exists between the rear side of the elastic hook 14 and the inner wall of the insulating base 13, as shown in fig. 1. In the non-secondary-lock connector 1, there may be a case where the metal terminal 11 is not positioned (i.e., not mounted), and the elastic hook 14 in the insulating base 13 deflects and cannot be hooked in the positioning groove 12 of the metal terminal 11, and at this time, there is no gap or a gap between the rear side of the elastic hook 14 and the inner wall of the insulating base 13 becomes small, as shown in fig. 2.
Typically, conventional probes in a testing device will have a 2mm measurement stroke (due to the amount of spring compression inside the conventional probe). The critical state that the terminal in the connector without the secondary lock is not positioned is often detected as qualified by mistake, and defective products are leaked.
In order to avoid false detection and reduce the outflow of defective products, manufacturers try to improve the detection accuracy by reducing the measurement stroke, but the detection accuracy is too high, the test is quite unstable, repeated tests are needed, the detection efficiency is greatly reduced, and the applicability is poor.
The inventor of the invention has conducted extensive research by means of long-term accumulated professional knowledge and familiarity with connector products, has summarized characteristics of connector products without secondary lock, and has specially developed and designed a terminal positioning detection device without secondary lock connector to conveniently and rapidly detect whether a terminal is positioned.
