Supply test finger, test marketing, test probe structures are shown in Figure

 I. Overview: The standard test finger, test marketing, test probe is all kinds of electrical safety standards for protection against electric shock as specified in the test apparatus for testing electrical products have a good structure and shell shock protection to ensure that when used not accidental contact with live parts. Second, the appearance of the structure: test finger, test marketing, test probe structures are shown in Fig Third, pay attention and use: 3.1, to prevent accidental contact of persons with live parts when the danger, in addition to operating the appliance shell holes needed for the operation shall not be opened a hole leading to a live part of II appliances shall not have access to basic insulation and open only basic insulation to metal parts separated from live parts of the holes. 3.2,0, II, holes or slits appliances, 0I and class I appliances other than metal parts connected to the ground terminal and ground contacts for holes or cracks and lamp, live parts of the socket other than the entrance hole, were used Figure 2 shows a test pin to the test, at each possible position, are used and the test pin inspection test finger, but not excessive force. 3.3, can not enter the test finger holes, the other with the same size with the test finger straight without test finger joints impose 20N force (used in conjunction with a force gauge) further testing, if the means to enter, use Figure 1 test finger shown re-test, the test finger through the hole; if the finger can not enter, put the force applied to 30N. If the protective device thus displaced or deformed hole so that the test finger shown in Figure 1 can be inserted without force, time and then test of Figure 1 Referring to the test, while in contact with the shock indicator. Test finger shall touch the exposed live parts and only paints, enamels, plain paper, cotton, oxide film, an insulating spacer beads or sealing filler for the protection of live parts. In addition, when tested with the test pin hole when the test pin must not touch the bare drive electric parts. For class II appliances, test finger shown in Figure 1 shall not touch live parts by basic insulation only separated from the metal parts. 3.4, in addition to class II appliances, but for only a switching operation can be cut off all the visible glow electric heating electrode assembly live parts and these electric components support member, as long as they do not open the lid from the outside of the appliance is clearly seen these parts in contact with the heating elements, as shown in Figure 3 should be used to test probe, and not with the test finger. Testing should not be too hard, the test probe shall not touch live electrical parts. 3.5, the standard test finger shall be designed to use only part of each of its joints relative to the central axis of the test finger is rotated 90 degrees in the same direction. 3.6, it is recommended to use light display contacts filament voltage is not less than 40V.
