Abstract
The technical scheme of the utility model discloses a relay measurement tool. The relay measurement tool comprises a housing, a connection opening located at the front end of the housing and a socket located at the tail of the housing; an adapter is embedded in the connection opening; plugging pins are embedded in the socket; the connection opening is connected with the plugging pins through power source lines; and the power source lines are provided with a switch. With the relay measurement tool of the utility model adopted, a measured relay is not needed to be disassembled from a whole set of equipment, and the measured relay is not needed to be disassembled. The relay measurement tool is advantageous in convenient use and accurate measurement results.
Description
Technical field
The utility model relates to dynamo-electric fields of measurement, relates in particular to a kind of relay survey instrument.
Background technology
At present, in the equipment place with relay, all need to judge by the resistance value of multimeter measuring relay the quality of relay, and measured relay will be removed from equipment set, more measured relay is taken apart, measure with multimeter.After having repaiied and installing, if broken down again, also will again dismantle and install, workload be large, wastes time and energy, and measurement result is also inaccurate.
Utility model content
The purpose of this utility model is to provide a kind of relay survey instrument, need not dismantle measured relay, just can judge whether measured relay damages.
The technical solution of the utility model is a kind of relay survey instrument, comprise shell, be positioned at the access port of this shell front end and the socket of described shell afterbody, described access port is embedded with adapter, described socket is embedded with contact pin, described access port is connected by power lead with described contact pin, on described power lead, has switch.Described access port connects the external ac power source of 220V, and relay is connected to the contact pin on described socket by wire, then closed described switch, then observe relay, if the blade of this relay outside normally swings, illustrate that this relay does not damage; If not swinging of this relay outside, illustrates that this relay does not damage.After measuring, disconnecting external power supply, cut-off switch, disconnects the connection of described socket and relay, determines whether to start the relay after maintenance is measured according to actual conditions.Compared to the prior art, the technical program does not need measured relay to remove from equipment set, does not need measured relay to take apart yet, uses easily, and measurement result is accurate.
Further, described power lead has 2, and described switch is positioned at wherein on a power lead; Described contact pin has 2, and every contact pin connects 1 power lead.After Closing Switch, the AC power that the AC power of 220V is 12V by adapter step-down, by power lead and contact pin, passes in measured relay metering circuit conducting.Do not need measured relay to remove from equipment set, also do not need measured relay to take apart, use easily, measurement result is accurate.
Further, described adapter is cylindrical, and the output voltage of this adapter is 12V.Easy to use, safe and reliable.
Further, switch is fixed on the outside of shell, compared to the prior art, easy to operate.
Beneficial effect: the technical program does not need measured relay to remove from equipment set, does not need measured relay to take apart yet, uses easily, and measurement result is accurate.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Mark in figure: 1-shell; 2-access port; 3-socket; 4-power lead; 5-contact pin; 6-switch.
Embodiment
Below in conjunction with accompanying drawing, preferably embodiment of the present utility model is described in further detail:
Referring to Fig. 1, a kind of relay survey instrument, comprise shell 1, be positioned at the access port 2 of this shell 1 front end and the socket 3 of described shell 1 afterbody, described shell 1 is rectangular parallelepiped, described access port 2 is embedded with adapter, described socket 3 is embedded with contact pin 5, and described access port 2 is connected by power lead 4 with described contact pin 5, on described power lead 4, has switch 6.Described access port 2 connects the external ac power source of 220V, relay is connected to the contact pin 5 on described socket 3 by wire, then closed described switch 6, then observe relay, if the blade of this relay outside normally swings, illustrate that this relay does not damage; If not swinging of this relay outside, illustrates that this relay does not damage.After measuring, disconnecting external power supply, cut-off switch 6, disconnects the connection of described socket 3 and relay, determines whether to start the relay after maintenance is measured according to actual conditions.Compared to the prior art, the technical program does not need measured relay to remove from equipment set, does not need measured relay to take apart yet, uses easily, and measurement result is accurate.
Referring to Fig. 1, described power lead 4 has 2, and described switch 6 is positioned at wherein on a power lead 4; Described contact pin 5 has 2, and every contact pin 5 connects 1 power lead 4.After Closing Switch 6, the AC power that the AC power of 220V is 12V by adapter step-down, by power lead 4 and contact pin 5, passes in measured relay metering circuit conducting.Do not need measured relay to remove from equipment set, also do not need measured relay to take apart, use easily, measurement result is accurate.
Preferably, described adapter is cylindrical, and the output voltage of this adapter is 12V.Columniform adapter and columniform plug are used in conjunction with, and avoid outer lead to be wound around or reverse the loose contact causing.Easy to use, safe and reliable.
Preferably, switch 6 is fixed on the outside of shell 1, compared to the prior art, easy to operate.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
