Accompanying drawing explanation
Fig. 1 is the housing surface structure schematic diagram of the utility model embodiment;
Fig. 2 is the relay input side structural representation of the utility model embodiment;
Fig. 3 is the relay outgoing side structural representation of the utility model embodiment;
Fig. 4 is the structural representation of the wire clamp of the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As Figure 1-Figure 4, the utility model embodiment comprises wire clamp 5, housing 6 and is arranged in the relay K M, direct supply 2, warning device etc. of housing 6, input line 1 one end being connected to relay K M is stretched into housing 6 neutral relay KM and is connected, and the other end is connected with wire clamp 5.
Specifically, relay K M is preferably auxiliary reclay, comprises input side, outgoing side, and as shown in Figure 2, its input side is connected with two input lines 1 for connection control loop; As shown in Figure 3, its outgoing side and the connection such as warning device, direct supply.Direct supply 2 is preferably battery etc., easily changes, and its two ends are connected with the outgoing side of relay K M, for power supplies such as warning devices.One of warning device preferably includes hummer 3, LED (light emitting diode) 4, both can certainly being.After hummer 3, LED4 series connection, be connected between relay K M and direct supply 2.
During application, when the input side of relay K M is connected on control loop, detect that control loop is charged, the outgoing side of relay K M closes, and direct supply 2 drives warning device to report to the police, and sounds a buzzer, light simultaneously, with reminding user.
As shown in Figure 2, Figure 4 shows, the free end 11 of input line 1 connects the wire clamp 5 for being clamped on control loop cable, pinching end 51 occlusal surface of wire clamp 5 is provided with the probe 52 for inserting cable insulation layer, even if like this for the cable being enclosed with insulation course, the present embodiment also can direct-detection, because the end of probe 52 is comparatively tiny, directly can wear out the cable insulation layer of control loop, thus directly contact with the metal core of cable.
More preferably, the length of probe 52 shortens gradually along the direction away from wire clamp 5 pinching end 51 end face, as shown in Figure 4, that is, near the position of wire clamp 5 rotating shaft, probe 52 region is shortened, because the probe 52 in outside is longer, can, by cable as between shorter probe 52, avoid wire clamp 4 from pinching end 51 landing.
As Fig. 1, the present embodiment comprises housing 6, and relay K M, direct supply 2, hummer 3, LED4 etc. are integrated in housing 6.For the ease of storage input line 1, the side of housing 6 is provided with square shape framework 7, and time idle, input line 1 is received in framework 7.
Further, framework 7 is extended with column 8 to central area, the side, end of column 8 is provided with rotating shaft 81, rotating shaft 81 is provided with the rotatable runner 9 for being wound around input line 1, runner 9 can rotate freely in the neutral gear of framework 7, its outer circumference, for being wound around input line 1, realizing input line 1 and is accommodated in object in framework 7.
More preferably, framework 7 is provided with through hole 71, and the free end of input line 1 is connected with wire clamp 5 through after through hole 71, and through hole 71 not only can provide guide effect for input line 1, and it is less than wire clamp 5, facilitates wire clamp 5 to be suspended on outside through hole 71.
When needs reclaim input line 1, in order to can quick rotation runner 9, side, side relative with column 8 on runner 9 be provided with handle 91.Column 8, handle 91 are positioned at the not ipsilateral of runner 9, and therefore the two is independent of each other.
During application, pull wire clamp 5, input line 1 is pulled out suitable length, two wire clamps 5 are linked on the positive and negative electric wire of control loop respectively, when control loop is charged, start auxiliary reclay KM, the loop conducting of auxiliary reclay KM junction closure, startup hummer 3 and LED4 realize sound and light of alarm simultaneously.
To sum up, the utility model energy very first time passes through sound, light warning reminding site work personnel control loop is charged, thus ensures personnel, test, device security.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
