Description
Technical field
The utility model relates to a kind of attachment plug, particularly a kind of press-contacting type Quick connector plug.
Background technology
1, instrument transformer is also called instrument transformer, is the general name of current transformer and voltage transformer, high voltage can be become low-voltage, big current becomes small area analysis, for measuring or protection system.Its function is mainly by high voltage or big current, and scaling transformation becomes normal low voltage (100A) or standard small area analysis (5A or 1A all refers to rated value), to realize standardization, the miniaturization of measuring instrument, proterctive equipment and automatic control equipment.Instrument transformer also can be used to separate high-voltage system simultaneously, to ensure the safety of the person and equipment.The normal operation of calibrating instrument transformer work to electric power system plays a very important role.
2, there is the problem that equipment is few, personnel are few in the work of calibrating instrument transformer at present, and calibration equipment is old, there is error, cannot ensure high efficiency work.The quality promoting calibrating is the major issue faced now.
3, now daily test is quantitatively many, and three district of county two equipment censorship amounts are large, distance, and the calibrating time limit is short, and specify to examine and determine in three days complete, greatly, task is very heavy, causes the difficulty of calibrating for workload.In certain hour, the number needs of calibration equipment will improve further.
4, when checking measuring equipment, a copper screw bolt nut of joint test cable and tested device clamps, when clamping with nut, firmly too little, because grip force deficiency easily makes conductor overheating, and affects assay; The firmly screw thread of too large easy damaged equipment again, the use of equipment after impact.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of press-contacting type Quick connector plug.
Its technical scheme is: comprise plug body, movable contact, compression spring, spring bonnet, adjusting nut, line ball nut, connecting hole, screw thread, internal thread is provided with at the A end of plug body, external screw thread is provided with at B end, movable contact is arranged on plug body inside, rubber blanket is placed with between movable contact and compression spring, the both sides up and down of compression spring are provided with spring bonnet, the right side of downside spring bonnet is provided with adjusting nut, the right side of adjusting nut is provided with line ball nut, adjusting nut and line ball nut connecting test current cable terminal stud; Equipment outlet port is provided with connecting hole, connecting hole connecting test voltage lead-out wire termination.
The A of above-mentioned plug body holds internal thread and B to hold external screw thread to adopt M12 screw thread respectively.
The beneficial effects of the utility model are: when checking measuring equipment, connect experimental facilities and clamped by a copper screw bolt nut of experimental facilities, the utility model press-contacting type Quick connector plug, namely solves when clamping with nut, firmly too little, because grip force deficiency easily makes conductor overheating, and affect experimental result, the firmly screw thread of too large easy damaged equipment again, the use of equipment after impact, improve inspection speed again, promote work quality and operating efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: plug body 1, movable contact 2, compression spring 3, spring bonnet 4, adjusting nut 5, line ball nut 6, connecting hole 7, internal thread 8, external screw thread 9.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises plug body 1, movable contact 2, compression spring 3, spring bonnet 4, adjusting nut 5, line ball nut 6, connecting hole 7, screw thread 8, internal thread 8 is provided with at the A end of plug body 1, external screw thread 9 is provided with at B end, it is inner that movable contact 2 is arranged on plug body 1, rubber blanket is placed with between movable contact 2 and compression spring 3, the both sides up and down of compression spring 3 are provided with spring bonnet 4, the right side of downside spring bonnet 4 is provided with adjusting nut 5, the right side of adjusting nut 5 is provided with line ball nut 6, adjusting nut 5 and line ball nut 6 connecting test current cable terminal stud, equipment outlet port is provided with connecting hole 7, connecting hole 7 connecting test voltage lead-out wire termination.
Wherein, the A of plug body 1 holds internal thread 8 and B to hold external screw thread 9 to be M12 screw thread, and the elastic force of compression spring 3 is at more than 2Kg.
When carrying out transducer check, the A of this Novel pressure touch Quick connector plug being held and connects upper instrument transformer respective threaded rod, tighten and make spring-compressed, produce larger elastic force, make movable contact and instrument transformer screw rod close contact, ensure that contact resistance is less, contact is good; Suitably adjust the height of adjusting nut subsequently, and current terminal is installed, screw line ball nut until the distance apart from two to three screw threads of outlet screw rod port is advisable; Voltage terminal is inserted connecting hole; Check wiring connection everywhere subsequently, just can start test.For needing a large amount of verifying works of carrying out, only Quick connector plug need be backed out, be installed to all the other tested instrument transformer screw rods just can, without the need to using the instruments such as spanner to assist, having saved the time, having reduced workload.Galvanic circle is followed successively by: instrument transformer screw rod, plug body, movable contact, extraction screw rod, test cable.
When checking measuring equipment, connect experimental facilities and clamped by a copper screw bolt nut of experimental facilities, the utility model press-contacting type Quick connector plug, namely solves when clamping with nut, firmly too little, because grip force deficiency easily makes conductor overheating, and affect experimental result, the firmly screw thread of too large easy damaged equipment again, the use of equipment after impact, improve inspection speed again, promote work quality and operating efficiency.
