Detailed Description

The present invention will be further described with reference to the accompanying drawings, and the following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in figures 1 to 3, the utility model discloses a small-size five metals terminal leaks puts detection structure, including burying mainboard 1 in injection mold, 1 center department of mainboard is provided with opening 3. The mainboard 1 has been seted up fixed orifices 8, is provided with fixing bolt 9 in the fixed orifices 8 for be connected with injection mold. The fixing holes 8 are located at both sides of the main plate 1 in the length direction. The front of mainboard 1 is seted up flutedly 2, and recess 2 is 4, is located mainboard 1's four corners department, specifically can adjust according to actual need. The number of probes 11 in a single groove 2 is 4, and the number can be adjusted according to actual needs.

An insulating fixing sleeve 10 penetrates through the main board 1 and is positioned in the groove 2, and the insulating fixing sleeve 10 plays an insulating role on the inner side and the outer side of the insulating fixing sleeve.
