Example one
In the process of assembling high-power electrical appliances (such as an electric water heater), a load lead is connected with a power line by generally adopting connection modes such as crimping, welding and the like. Connecting the load wire usually needs to bear a larger current, if the connection is not good (usually expressed as a small contact area), the resistance at the wire connection increases, and the heat is serious in the long-time operation process, causing the wire damage, and then the electrical appliance damage. Based on the fact that no detection device suitable for instantly detecting the wire connection quality along with production assembly on a production line exists at present, the detection device for the wire connection quality has a detection blind spot, as shown in fig. 1, the utility model provides a wire connection detection device, which comprises a plurality of detection probes 11, a detection processing module 12 and a supporting component 13, wherein the detection probes 11 are provided; the detection processing module 12 has detection terminals connected with the detection probes 11 in a one-to-one correspondence manner, and the detection processing module 12 is used for acquiring one or more of resistance, current and voltage among the detection probes 11; the inspection processing module 11 and the inspection probe 12 are respectively provided on the support assembly 13.
When the lead connection detecting device of the present embodiment is used, the detecting probes 11 are respectively inserted onto the connecting leads to be detected, the connecting leads are at least two, as shown in fig. 2 and fig. 3, in the present embodiment, two connecting leads are taken as an example for description, the two connecting leads include a first lead 21 and a second lead 22, two detecting probes 11 are correspondingly provided, one detecting probe 11 is connected with the first lead 21, and the other detecting probe is connected with the second lead 22. The detection processing module 12 can form a current loop by outputting a voltage or a current to the detection probe 11, and by acquiring one or more parameters of the resistance, the current, and the voltage between the detection probes 11, that is, the resistance, the current, or the voltage between the first wire 21 and the second wire 22. The quality of wire connection is embodied in the aspect of electrical parameters and comprises the following steps: when the connection quality is poor, the contact area of the connection part is small, the corresponding resistance is increased, if a constant voltage is output to the connection part, the current passing through the connection part is reduced, if a constant current is output to the connection part, the voltage at two ends of the connection part is increased, or the resistance between the connection wires is directly measured, and the connection quality of the wires can be judged by the above modes. The test can be realized by using the existing detection circuit. When the detection parameters meet the set limit values, the connection can be judged to be good, otherwise, the connection is poor.
As shown in fig. 3, when connecting a load wire of an electric water heater, a connection wire is usually crimped and fixed by a screw 40, so as to facilitate the operation of a production line, the wire connection detection device of the present embodiment further includes a screwing device 30, and the screwing device 30 is fixed to the support component 13. During the production line operation, the screwing device 30 drives the screw 40 to rotate, so as to fixedly connect the connecting wires. After screwing, the detection probes 11 are respectively detected to the connecting wires to be detected, so that connection detection of the connecting wires is realized. The device integrates the functions of screwing and detecting, and can greatly improve the production efficiency.

The second support portion 132 compresses the first spring 144 at this time. When the coil 141 is disconnected from the power supply, the magnetic lines of force in the iron core 142 disappear, the armature 143 is no longer attracted, and the second supporting portion 132 moves away from the first supporting portion 131 under the elastic force of the first spring 144.
