Abstract
The utility model relates to a safety protective rubber plug, which comprises a plug body and a cylinder-shaped pin fixedly connected with the plug body, wherein the plug body and the cylinder-shaped pin are made of rubber. The safety protective rubber plug provided by the utility model can prevent misplug and avoid occurrence of accidents.
Description
Technical field
The utility model relates to a kind of safeguard protection rubber plug.
Background technology
At present, the error testing work of electric energy meter mainly is divided into laboratory error testing and site error test.No matter be tested standard electric energy meter in laboratory or the standard electric energy meter tester that uses at the scene, all belong to the high accuracy expensive instrument, the input of the voltage and current of many testers all adopts jack type, but the shape of the needed low pressure input jack of the instrument that has is the same with the pattern of high pressure input jack, the position on same row and from very near (as the multi-functional standard electric energy meter of CL311V2), measurement verification personnel or staff have carelessness slightly, just probably tested high voltage plug is inserted in the low pressure jack, or with tested pressure-wire and electric current line wrong plug position, thereby cause the damage of precision instrument, cause the generation of field accident.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can prevent the wrong plug jack, the safeguard protection rubber plug of avoiding accident to take place.
The utility model adopts following technical scheme:
The utility model comprises plug body and the cylindricality pin of fixedlying connected with plug body; The material of described plug body and cylindricality pin is a rubber.
Described cylindricality pin is cylindrical pin or square column type pin.
Described cylindricality pin is made up of two fixedly connected cylindricality pins, and the overall dimension of the cylindricality pin of close plug body one side is greater than the overall dimension of another one cylindricality pin.
Good effect of the present utility model is as follows:
When the laboratory verification master meter, the utility model plug is injected in the jack that has nothing to do with test, jack is closed, after test is finished, again this plug is taken off and restPose, avoided effectively taking place owing to plug mistake jack causes the phenomenon of instrument damage.
When some technical parameters such as electric energy meter error, voltage, electric current and power of scene operation being tested with electric energy meter on-site calibrator; electric energy meter on-site calibrator current input terminal is jack type; be respectively 10A, 5A and 1A; the 0.5A in addition that has; will be before test according to the size of tested electric current; the patch jack of rational selection check instrument; to temporary transient no electric current input jack; seal with the utility model safeguard protection rubber plug, thereby effectively protect electric energy meter on-site calibrator normally to move.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is provided with two pin configuration schematic diagrames for the utility model.
In the accompanying drawings, 1 plug body, 2 cylindricality pins.
Embodiment
As shown in Figure 1, the utility model comprises plug body 1 and the cylindricality pin 2 of fixedlying connected with plug body 1, in the reality, can cylindricality pin 2 be made cylindrical pin or square column type pin according to the shape of jack.As shown in Figure 2, cylindricality pin 2 is made up of two fixedly connected cylindricality pins, and the overall dimension of the cylindricality pin of close plug body one side can be inserted in the jack of different size greater than the overall dimension of another one cylindricality pin.When the jack size was big, the larger-size part of pin contacted with jack; When the jack size hour, the less part of pin size contacts with jack, realizes the function of using more.In the use, be provided with twill, can prevent to skid, the convenient use on plug body 1 surface.
The material of the utility model plug body 1 and cylindricality pin 2 is a rubber, and rubber itself has good insulation and elasticity, can closely contact with jack, is inserted into to be not easy in the hole to drop out, and has avoided loosening phenomenon to occur.
When the laboratory verification master meter, the utility model plug is injected in the jack that has nothing to do with test, jack is closed, after test is finished, again this plug is taken off and restPose, avoided effectively taking place owing to plug mistake jack causes the phenomenon of instrument damage.
When some technical parameters such as electric energy meter error, voltage, electric current and power of scene operation being tested with electric energy meter on-site calibrator; electric energy meter on-site calibrator current input terminal is jack type; be respectively 10A, 5A and 1A; the 0.5A in addition that has; will be before test according to the size of tested electric current; the patch jack of rational selection check instrument; to temporary transient no electric current input jack; seal with the utility model safeguard protection rubber plug, thereby effectively protect electric energy meter on-site calibrator normally to move.
In real life, plug can be made into difformity as required, as the supply socket that family uses, has also having of rectangle circular, can prevent effectively that the child mistake from bumping power supply and the phenomenon of getting an electric shock.
