Technical Field
The utility model relates to an electrical online testing device for a fresh air exchanger, and belongs to the field of electrical testing tools.
Background
The new trend switch is after the equipment is accomplished, and electrical performance test will all be carried out to every machine, and traditional test mode adopts the alligator clip to press from both sides on the terminal of new trend switch, carries out the circular telegram and detects, and its shortcoming is: the crocodile clip has the advantages of high labor intensity, low wiring speed and low efficiency, and particularly, the crocodile clip is easy to drop, so that an electric shock accident occurs to an operator, and serious potential safety hazards exist.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides the electric on-line testing device for the fresh air exchanger, which is convenient to operate, reliable in clamping, high in efficiency and good in safety.
The technical scheme of the electric on-line testing device of the fresh air exchanger is as follows: the testing device is characterized by comprising a clamping support, wherein the upper part of the clamping support is provided with a flat plate bent to one side, an insulating seat is arranged on the flat plate, 5 or 6 testing probes are arranged in the insulating seat, the upper end of each testing probe is provided with a wiring terminal, the lower end of each testing probe is provided with a spring, the lower part of the clamping support is provided with two support legs bent to one side, each support leg is provided with a baffle bent upwards, and a magnet is arranged below each support leg.
When the device is used, the device is fixed on the shell of the fresh air exchanger (the shell of the conventional fresh air exchanger is made of iron) conveniently and reliably by virtue of the suction force of the magnet, the baffle 7 can be blocked on the side wall of the shell, the gravity center of the device is effectively prevented from inclining forwards, the device is placed more stably, two support legs are provided, the two support legs can be connected by avoiding the ground wire, 5 or 6 test probes are provided, wiring and contact can be performed according to different types of machines, and the device is labor-saving and convenient to operate, high in wiring speed and high in efficiency. Particularly, the device can not fall off during testing, effectively prevents electric shock accidents, eliminates potential safety hazards and has good practicability.
According to the electric online testing device for the fresh air exchanger, the wiring terminal is an O-shaped terminal and is fixed at the upper end of the testing probe through the nut, the O-shaped terminal is convenient to wire, and the nut is firmly fixed. The clamping support is an iron sheet support, the flat plate and the support legs are bent through metal plates, the cost of the iron sheet support is saved, and the metal plates are convenient to form. The insulating seat is fixed on the flat plate through screws, and the fixing is convenient. The insulating seat on set up the perforation corresponding with test probe quantity, the test probe passes the perforation to be equipped with the spacing collar in the middle part of test probe, the test probe can reciprocate about 10mm, relies on the spring top to exert tight power in top and reset force on the spacing collar, the contact is more reliable.

Detailed Description
The utility model relates to an electrical online testing device for a fresh air exchanger, which comprises a clamping support 1, wherein the upper part of the clamping support is provided with a flat plate 2 bent towards one side, an insulating seat 3 such as a bakelite plate and the like is arranged on the flat plate, 5 or 6 testing probes 4 are arranged in the insulating seat, the upper end of each testing probe 4 is provided with a wiring terminal 5, the lower end of each testing probe 4 is provided with a spring 13, the lower part of the clamping support is provided with two support legs 6 bent towards one side, each support leg 6 is provided with an upward bent baffle 7, and a magnet 8 is arranged below each support leg 6. During the use, rely on magnet 8's suction, it is both convenient to fix this device on the casing of new trend switch (the casing of new trend switch all is iron at present), and is reliable again, baffle 7 can keep off on the lateral wall of casing, effectively prevents that the focus of this device from leaning forward, place more steadily, stabilizer blade 6 has two, can avoid the ground wire between two stabilizer blades to connect, test probe 4 has 5 or 6, can be according to different models wiring and contact, the operation is laborsaving, it is convenient, the wiring speed is fast, high efficiency. Particularly, the device can not fall off during testing, effectively prevents electric shock accidents, eliminates potential safety hazards and has good practicability. The wiring terminal 5 is an O-shaped terminal and is fixed at the upper end of the test probe 4 through a nut 9, the O-shaped terminal is convenient to wire, and the nut is firmly fixed. The clamping support 1 is an iron sheet support, the flat plate 2 and the support legs 6 are bent through a metal plate, the cost of the iron sheet support is saved, and the metal plate is convenient to form. The insulating base 3 is fixed on the flat plate 2 through a screw 10, and the fixing is convenient. Insulating seat 3 on set up and test probe 4 corresponding perforation 11 of quantity, test probe 4 passes perforation 11 to be equipped with spacing collar 12 in the middle part of test probe, about 10mm can reciprocate to the test probe, rely on the spring top to exert tight power and the power that resets on the spacing collar, the contact is more reliable.
