Existing electric power connecting clamps there will be the situation connecting and loosen after a long time use, after the connection of electric power coupled situation value loosens, owing to cannot learn that it uses rear connection situation timely, thus cannot overhaul in time, and loosen due to the connection between itself and wire and cause occurring gap between connecting clamps and wire, thus in use generate heat because of overload operation, cause the mass energy waste on transmission facility.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of electric power connecting clamps with heating alarm function.
Solve the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:
A kind of electric power connecting clamps with heating alarm function, comprise wiring clip shell, fixture for fixing cord is installed in wiring clip shell, wiring clip shell is provided with installing hole, installing hole internal fixtion has the heating alarming device of reporting to the police for conductor overheating, it is characterized in that: described heating alarming device comprises light-emitting diode, sensitive switch, bimetal leaf and power supply; Light-emitting diode, sensitive switch and power sources in series form closed-loop path, inconsistent with the moving contact of sensitive switch on the hole wall that bimetal leaf is fixed on described installing hole, the deformation that bimetal leaf produces when reaching preset temperature can drive the moving contact of sensitive switch and fixed contact to connect.
As a kind of execution mode of the present utility model, described heating alarming device also comprises insulating support, described light-emitting diode, sensitive switch and power supply are all fixed on insulating support, and described sensitive switch is arranged towards the fixed position of described wire in wiring clip shell.
As a kind of execution mode of the present utility model, described power supply is button cell.
In order to improve heating alarming device to the sensitiveness of wire temperature rise, improve as one of the present utility model, described installing hole is arranged near the fixed position of described wire in wiring clip shell.
As preferred implementation of the present utility model, described installing hole is the through hole being parallel to the setting of described wire, and the lower port of this through hole is embedded with end cap, and described heating alarming device is seated on end cap, and described light-emitting diode exposes from the upper port of this through hole.
As preferred implementation of the present utility model, the wire that described wiring clip shell each root fixture corresponding is fixed is provided with a described installing hole, and, be all fixed with a heating alarming device in each installing hole.
Compared with prior art, the utility model has following beneficial effect:
The utility model, by arranging heating alarming device in the wiring clip shell of electric power connecting clamps, achieves the heating warning to this electric power connecting clamps and wire, so that maintainer learns that these electric power connecting clamps or wire exist potential safety hazard intuitively.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the vertical view of electric power connecting clamps of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the electric power connecting clamps with heating alarm function of the present utility model, comprise wiring clip shell 1, fixture 3 for fixing cord 2 is installed in this wiring clip shell 1, and, the wire 2 that wiring clip shell 1 each root fixture 3 corresponding is fixed is provided with an installing hole 1a, is all fixed with a heating alarming device of reporting to the police for conductor overheating in each installing hole 1a.
Above-mentioned installing hole 1a is arranged near the fixed position of corresponding lead 2 in wiring clip shell 1, and this installing hole 1a is the through hole being parallel to wire 2 setting, and the lower port of through hole is embedded with end cap 8.
Above-mentioned heating alarming device is seated on end cap 8, and it comprises insulating support, light-emitting diode 4, sensitive switch 5, bimetal leaf 6 and power supply 7.Light-emitting diode 4, sensitive switch 5 and power supply 7 are all fixed on insulating support, light-emitting diode 4, sensitive switch 5 and power supply 7 closed-loop path in series, further, light-emitting diode 4 exposes from the upper port of through hole, and sensitive switch 5 is arranged towards the fixed position of wire 2 in wiring clip shell 1.Inconsistent with the moving contact 501 of sensitive switch 5 on the hole wall that bimetal leaf 6 is fixed on installing hole 1a, the deformation that bimetal leaf 6 produces when reaching preset temperature can drive the moving contact 501 of sensitive switch 5 to connect with fixed contact 502.Wherein, above-mentioned power supply 7 can adopt button cell, and the preset temperature of bimetal leaf 6 is determined by himself.
Operation principle of the present utility model is as follows:
When making the electric current in wiring clip shell 1 increase because electric power connecting clamps of the present utility model connect the reasons such as the clamping loosening i.e. fixture 3 pairs of wires 2 loosens, and when causing wiring clip shell 1 overheated, the bimetal leaf 6 contacted with wiring clip shell 1 heats up and reaches its preset temperature, bimetal leaf 6 is made to produce deformation and curve inwardly, thus drive the moving contact 501 of sensitive switch 5 to connect with fixed contact 502, power supply 7 is powered to light-emitting diode 4 thus, light-emitting diode 4 is lighted, so that maintainer can learn that these electric power connecting clamps or wire 2 exist potential safety hazard very intuitively, thus overhaul.
