[0002] Relay is a kind of electric control device, and it plays the roles of automatic regulation, safety protection and conversion circuit in circuit. To ensure the normal operation of power system, the relay needs to be detected periodically to ensure its normal function, and the traditional detection method is to connect the detection clamp and the foot of the relay by the cooperation of multimeter and detection clamp, then detect the resistance value and other values by multimeter to judge the work of the relay. Since the foot of the relay is more and the spacing is smaller, in order to improve the detection efficiency, the existing equipment changes the connection mode of the foot and the detection clamp, and connects by plug-in mode. However, since the size of the foot is small, and when the foot is plugged, the hole and the surface of the equipment are in a plane state, which causes the foot to be unable to be accurately inserted into the plug-in hole due to the unclear position of the hole, thereby causing the equipment to be inconvenient to use and the plug-in accuracy to be poor. For example, the patent No. CN202420406487.2 discloses a technical solution, which has the above-mentioned problems, and the equipment cannot accurately plug in during testing, and the foot cannot be cleaned, which may cause the resistance value to be inaccurate during testing, thereby affecting the test result.

[0029] As the utility model is preferred, the cleaning assembly further comprises a sliding rod 13 which is slidingly arranged on the plug-in pipe 3 and has an end fixedly arranged on the cleaning ring 12, and a second spring member 15 is sleeved on the sliding rod 13 and used for resetting the sliding rod 13, two pressing plates 14 are rotatably arranged on the plug-in pipe 3, and the end of the sliding rod 13 is hingedly connected with the pressing plate 14, which is used for cleaning the inserted heel and ensuring the cleanliness of the surface of the heel, so as to avoid that impurities and foreign matters affect the resistance value of the detection, thereby affecting the detection result when the equipment is used.
[0030] The working principle of the utility model is as follows:
[0031] Reference Figure 1 The initial position of the plug-in pipe 3 is located in the detector body 1, and a plurality of holes corresponding to the plug-in pipe 3 are formed in the front side of the detector body 1, so that the plug-in pipe 3 can be moved out, and the position of the plug-in pipe 3 is arranged corresponding to the mounting position of the relay heel.
[0032] Reference Figure 3 When in use, the detector body 1 and the relay are placed correspondingly, at this time, the limiting rod 9 and the limiting frame 11 are in movable contact, and when the moving plate 2 is moved by being pushed, the connecting rod 5 slides in the detector body 1, and at the same time, the first spring member 4 is elongated along with the movement of the moving plate 2, since the torsional spring member 10 is sleeved between the limiting rod 9 and the fixed frame 8, the limiting rod 9 is subjected to the torsional force of the torsional spring member 10, so that the limiting rod 9 is offset upwardly based on the fixed frame 8, when the moving plate 2 drives the limiting rod 9 to move forwardly, the limiting rod 9 will rotate downwardly, and when the moving plate 2 stops moving, the torsional force of the torsional spring member 10 will drive the limiting rod 9 to rotate upwardly, and at the same time, the elastic force of the first spring member 4 is used to form a resistance between the limiting frame 11 and the limiting rod 9, so as to keep the moving plate 2 fixed and keep the plug-in pipe 3 fixed, and when the plug-in pipe 3 is exposed outside the detector body 1, the plug-in pipe 3 can be quickly and accurately matched with the heel, so that the heel can be quickly inserted into the plug-in pipe 3, thereby avoiding that the surface of the detector body 1 is too close to the surface of the relay, so as to affect the stability and accuracy of the insertion.
[0033] Reference Figure 4When the plug-in pipe 3 moves out of the detector body 1, the pressing plate 14 is pressed due to the inclined state of the pressing plate 14, at this time, the pressing plate 14 pushes the two slide rods 13 to be close to each other, and the second spring member 15 is elongated, and at this time, the plug passes through the two cleaning rings 12, the extrusion friction between the cleaning rings 12 can effectively clean the impurities on the surface of the plug, avoid the influence of the foreign matters and impurities on the surface of the plug on the resistance value of the detection;
[0034] Reference Figure 3 After the detection is completed, the connecting rod 5 is pushed to the side of the moving plate 2, at this time, the connecting rod 5 drives the limiting rod 9 to move, and the limiting rod 9 and the limiting frame 11 are separated, at this time, the elastic force of the first spring member 4 drives the moving plate 2 to reset, and then the plug-in pipe 3 is reset, so that the convenience of the equipment is realized;
[0035] The moving plate 2 in the equipment pushes out the plug-in pipe 3, so that the equipment can not only plug in the plane, but also make the plug-in pipe 3 located outside the detector body 1, so that the equipment is more accurate when plugging, avoids that the distance between the two planes is too close when plugging, so that the position of the plug-in pipe 3 cannot be observed when plugging, thereby affecting the plug-in accuracy of the equipment, and when the plug-in pipe 3 moves out, the cleaning ring 12 in the cleaning assembly can clean the plug of the relay, thereby effectively ensuring the cleanliness of the plug, avoiding that the plug contains foreign matters, causing the resistance value to change during the detection of the equipment, thereby affecting the detection accuracy of the equipment.
