Description

Technical Field

[0002] When wiring power equipment, the cable needs to be connected from one position to another. At this time, the cable often needs to be bent at a certain angle to complete the wiring. However, if the bending angle of the cable is too large or the force on the bent part is too large, it is very likely to damage the insulation layer of the cable. Once the insulation layer of the cable is damaged, the current may leak, causing a short circuit or electric shock accident. To avoid the above adverse situations, we propose a connector for testing power grid power equipment. Content of the Utility Model

[0003] The purpose of the utility model is to provide a connector for testing power grid power equipment. By setting a support mechanism, it can relieve the bending angle and force of the cable, and play a good protective role in the connection part between the cable and the first connector, solving the problem that if the bending angle of the cable is too large or the force on the bent part is too large, it is very likely to damage the insulation layer of the cable.

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0013] The utility model has the following beneficial effects:

[0014] By providing a supporting mechanism, when the cable bends to one side during wiring of the power equipment, the cable will contact the corresponding positioning wheel, which can alleviate the angle and strength of the cable bending, and provide good protection for the connection part between the cable and the first connector, thereby preventing the first connector and the cable connection end from being damaged by bending and loosening.

There are four support mechanisms 2, and the four support mechanisms 2 are evenly distributed on the outer wall of the cable 6. By setting the support mechanism 2, it plays a good protective role in the connection part between the cable 6 and the first connector 1, thereby preventing the connection end of the first connector 1 and the cable 6 from being bent and damaged and loosening;

[0029] The connection mechanism 3 includes a dust-proof component, a connection component, and a fixing component. The dust-proof component includes a connection sleeve 31 slidably connected to the outer wall of the first connector 1. A chute 32 is opened on the connection sleeve 31. A baffle 33 is slidably connected to the inner wall of the chute 32. Before the first connector 1 and the second connector 5 are connected, the baffle 33 can be slid into the chute 32 on the connection sleeve 31, so that the baffle 33 protects the connection part of the first connector 1 and prevents dust from contaminating the connector, having a certain dust-proof effect;

[0030] The connection component includes two fixed rods 35 fixedly connected to the outer wall of the first connector 1. One end of each of the two fixed rods 35 away from the first connector 1 is hinged with a positioning rod 36. An inclined block 37 is fixedly connected to each of the two positioning rods 36.

The left ends of the two third springs 45 are fixedly connected to the right side surfaces of the two sliders 43 respectively. When the baffle 33 is inserted into the inner part of the chute 32 to protect the connection part of the first connector 1, the third springs 45 are in a stretched state, so that the right side surface of the baffle 33 can be tightly attached to the right end of the first connector 1 through the stretched third springs 45, increasing the frictional force between the first connector 1 and the baffle 33, and further preventing the baffle 33 from sliding out of the chute 32;

[0034] A specific application of this embodiment is as follows: By providing the support mechanism 2, when wiring the power equipment causes the cable 6 to bend to one side, the cable 6 will come into contact with the corresponding positioning wheel 25, causing the positioning wheel 25 to press the corresponding first sliding rod 23 to extend outwards. At the same time, the U-shaped fixing frame 24 and the L-shaped fixing rod 22 cooperate with each other, so that the first spring 26 on the corresponding positioning wheel 25 is compressed, which can relieve the bending angle and strength of the cable 6, play a good protective role for the connection part between the cable 6 and the first connector 1, and further prevent the connection end between the first connector 1 and the cable 6 from being bent and damaged and loosened;

[0035] By providing the connecting mechanism 3, before the first connector 1 and the second connector 5 are connected, the baffle 33 can be slid into the slide groove 32 on the connecting sleeve 31, so that the baffle 33 protects the connection of the first connector 1 to prevent dust from polluting the connector, and has a certain dust-proof effect. When the baffle 33 protects the first connector 1, the clamping ring 34 is located in the middle of the bevel block 37. At this time, the second spring 393 is stretched, and under the mutual cooperation of the fixing rod 35, the positioning rod 36, the bevel block 37, the clamping block 38, the connecting shaft 391 and the connecting block 392, the two clamping blocks 38 spread outward, and the clamping blocks 38 are away from the first connector 1, and when the first connector 1 and the second connector 5 are connected When the first connector 1 and the second connector 5 are connected, the connection ring 46 contacts with the connecting sleeve 31 and pushes the connecting sleeve 31 to move to the right, so that the clamping ring 34 slides to the right on the bevel block 37, and the stretched second spring 393 is released. The fixing rod 35 and the positioning rod 36 cooperate with each other, and the two clamping blocks 38 approach each other and fit with the left side surface of the second connector 5, so as to fix the connection between the first connector 1 and the second connector 5, which greatly improves the stability of the connection. When the first connector 1 and the second connector 5 need to be disassembled, the positioning rod 36 can be pulled outward to rotate the positioning rod 36 around the fixing rod 35, so as to make the clamping block 38 away from the second connector 5, so that the two connectors can be quickly disassembled.

[0036] By providing a locking mechanism 4, when the baffle 33 is inserted into the slide groove 32 and protects the connection of the first connector 1, since the connecting sleeve 31 and the slider 43 are fixed by the connecting rod 44, and the slider 43 is slidably connected to the inner wall of the fixed frame 41, the third spring 45 is in a stretched state, so that the right side surface of the baffle 33 can be tightly fitted with the right end of the first connector 1 through the stretched third spring 45, thereby increasing the friction between the first connector 1 and the baffle 33, thereby preventing the baffle 33 from sliding out of the slide groove 32, and after the baffle 33 is pulled out of the slide groove 32, the stretched third spring 45 is released, and the slider 43 slides to the right on the second slide rod 42 while driving the connecting sleeve 31 to move to the right, so that the first connector 1 and the second connector 5 can be connected.
