Description
Technical Field
The invention belongs to an electric conduction detection instrument, and particularly relates to a temperature controller conduction performance detection pen which is not conducted at normal temperature.
Background
The test of the conduction performance of the temperature controller which is not conducted at normal temperature refers to that the temperature controller which is not conducted at normal temperature is in a conduction state or a non-conduction state by using a test pen again before leaving a factory after the temperature controller is subjected to final appearance inspection. After the final appearance inspection is performed on the temperature controller conducted at normal temperature, when two probes of the test pen are contacted with two terminals of the temperature controller at natural environment temperature, the buzzer of the test pen sounds because the fixed contact and the movable contact of the temperature controller conducted at normal temperature are contacted, so that the temperature controller conducted at normal temperature is judged to be in a conducting state and an OK state, and the temperature controller can be delivered from a factory. And the temperature controller that does not conduct at normal temperature, such as a low-temperature product and a common Y-type product, the fixed contact and the movable contact are disconnected at natural environment temperature, that is, after the temperature controller that does not conduct at normal temperature is subjected to final appearance inspection, and at natural environment temperature, when two probes of the test pen are in contact with two terminals of the temperature controller, the buzzer of the test pen is in a disconnected state because the fixed contact and the movable contact of the temperature controller that does not conduct at normal temperature are disconnected, and the whole circuit is in an open state without any sound, so that the temperature controller that does not conduct at normal temperature is judged to be in a non-conducting state, that is, an OK state, and can leave a factory.
In a word, under the natural environment temperature, the test pen is used for detecting the temperature controller which is conducted at the normal temperature, and the buzzer of the test pen sounds to be in an OK state; and the buzzer of the test pen does not sound and is in an OK state when the temperature controller for detecting non-conduction at normal temperature detects that the temperature controller is not conducted at normal temperature. Because the normal-temperature conducting type and the normal-temperature nonconducting type of each temperature controller produced by the production line are switched at any time, a detector also needs to continuously remember whether the buzzer sounds OK or not in the mind, and particularly when defective products exist in the normal-temperature nonconducting temperature controllers of the same type, the detector is easy to confuse and make wrong judgment, thereby bringing great hidden danger to manufacturers and clients.

Detailed Description
In the embodiment, referring to the attached drawings, a temperature controller conduction performance detection pen which is not conducted at normal temperature comprises a detection pen holder 3, shoulders 3-1 are arranged on the outer sides of the upper end and the lower end of the detection pen holder 3, an upper pen cover 10 is in threaded connection with the inner side of the shoulder 3-1 on the upper end, a pen cap 9 is tightly matched and installed on the shoulder 3-1, and a hook 6 is fixed on the pen cap 9, wherein an upper partition plate 13 is fixed on the upper portion in a cavity of the detection pen holder 3 through a countersunk screw 11, a middle partition plate 14 is fixed in the middle of the cavity, and a sealing cover 1 is fixed at the lower end of the detection pen holder 3; the inner side probe 4 is movably arranged in the holes arranged at the two sides of the middle partition plate 14, the upper end of the inner side probe 4 is welded with a lead 12, the buzzer 7 is arranged in the middle of the lead 12, and the buzzer 7 is fixed below the upper partition plate 13; two through holes 1-1 are symmetrically arranged on the sealing cover 1, a cylindrical outer probe 2 is movably arranged in the through holes 1-1, and an insulating layer 2-1 is fixed on the inner wall of the outer probe 2; the inner side probe 4 arranged in the hole of the insulating layer 2-1 is provided with a spring 5, the upper end of the spring 5 is fixed below the middle partition plate 14, and the lower end is fixed at the lower end of the inner side probe 4; the upper ends of the two outer probes 2 are connected in series with a battery 8 by a lead 12, and the battery 8 is arranged on the upper partition plate 13.
The height difference between the lower end surfaces of the inner probe 4 and the spring 5 and the outer probe 2 is H, and H is 10-20 mm.
The design principle and the detection method of the invention are as follows: when the conduction state of the temperature controller 15 which does not conduct at normal temperature in a state where the fixed contact 15-1 and the movable contact 15-2 are disconnected under the natural environment temperature is detected, the principle that the current only passes through the line with small resistance in the parallel circuit is used. The detection method comprises the following steps: the detection pen holder 3 is downwards, the inner side probe 4 is firstly contacted with two terminals 16 of a temperature controller 15 which is not conducted at normal temperature to be detected, then the outer side probe 2 is also contacted with the terminals 16 by pressing downwards, because a fixed contact 15-1 and a movable contact 15-2 in the temperature controller 15 which are not conducted at normal temperature are disconnected at the natural environment temperature, current passes through the right outer side probe 2, the right terminal 16, the right inner side probe 4, the buzzer 7, the left inner side probe 4, the left terminal 16 and the left outer side probe 2, and the buzzer 7 rings to indicate that the temperature controller 15 which is not conducted at normal temperature is OK qualified; if the fixed contact 15-1 and the movable contact 15-2 are in contact, the current passes through the right outer side probe 2, the right terminal 16, the movable contact 15-2, the fixed contact 15-1, the left terminal 16 and the left outer side probe 2, the current does not pass through the buzzer 7 and does not make a sound, and the temperature controller 15 which is not conducted at normal temperature is a non-qualified product. During detection, the spring 5 is compressed, detection is finished, and as long as the detection pen holder 3 is not pressed, the elastic force of the spring 5 can automatically lift the pen, so that the outer side probe 2 is lifted for a distance H.
