Abstract
The utility model discloses a secondary control loop detection device. The key is that the device comprises a shell and a circuit arranged in the shell, wherein the circuit comprises a power source; one pole of the power source is sequentially connected in series with a resistor R, a buzzer and a light-emitting diode connected in parallel and a contact B through a lead wire, and the other pole of the power source is provided with a contact A in a connecting manner; the buzzer and the light-emitting diode are arranged on the upper surface of the shell; the shell is provided with a hole; and the lead wire which connects the contact A with the contact B is led out from the hole. The secondary control loop detection device, disclosed by the utility model, is simple in structure, small in volume, convenient to carry, low in cost, easy to operate, convenient for the front-line workers in a factory to use, capable of greatly improving first-pass yield of secondary loop wiring in a power distribution device and suitable for the work sites and fields with dark light and poor illumination condition as well as high noise.
Description
Technical field
The utility model relates to a kind of circuit checker.
Background technology
In various controller switching equipment secondary control loops, because feeder number is more, the wire size use amount is big, the situation that wrong occurs or miss through regular meeting.In order to guarantee the connection in loop, generally adopt multimeter to detect, but multimeter cost an arm and a leg, the higher and part producing shop floor worker of cost can not use, and has directly had influence on the first-time qualification rate of product.
The utility model content
The purpose of the utility model provides a kind of simple in structure, easy to operate secondary control loop pick-up unit.
To achieve these goals; Adopt following technical scheme: a kind of secondary control loop pick-up unit; It is characterized in that: said device comprises housing and the circuit that is arranged in the housing, and wherein circuit comprises power supply, and a utmost point of power supply is in series with hummer and light emitting diode, the contact B of resistance R, parallel connection successively through lead; Another utmost point of power supply is connected with contact A; Wherein hummer and light emitting diode are arranged in the upper surface of housing, have the hole on the housing, and the lead of connecting terminal A and contact B is drawn in the hole.
Wherein said power supply is a rechargeable battery.
The utility model circuit structure is simple, and volume own is little, is easy to carry, with low cost; Simple to operate; The workman of being convenient to factory's one line uses, and has significantly improved the first-time qualification rate of secondary circuit wiring in the controller switching equipment, is applicable to production scene, rather dark underlit, place that noise is big.
Description of drawings
Fig. 1 is the external structure of the utility model;
Fig. 2 is the circuit theory diagrams of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
As depicted in figs. 1 and 2, a kind of secondary control loop pick-up unit comprises housing 3 and the circuit that is arranged in the housing; Wherein circuit comprises power supply, and a utmost point of power supply is in series with resistance R, hummer 1 and the light emitting diode 2 of parallel connection, contact B successively through lead, and another utmost point of power supply is connected with contact A; Wherein hummer and light emitting diode are arranged in the upper surface of housing; Have the hole on the housing, the lead of connecting terminal A and contact B is drawn in the hole, and power supply can be selected rechargeable battery for use.
When detecting secondary control loop, only need contact A and contact B be inserted the loop, correct if the loop connects, the circuit in the housing forms the loop so, lumination of light emitting diode, hummer is sounded simultaneously, otherwise, the two equal attonity.
