Description

Technical Field

[0001] The utility model relates to an AC contactor connection structure, and more specifically, to an AC contactor connection structure. Background Art

[0002] An AC contactor is an automatic switching device that connects or disconnects the main circuit of a motor or load. It uses electromagnetic force to close or disconnect the switch. It is suitable for frequent operation and remote control of high-voltage circuits, and has low-voltage release protection performance.

[0003] The connection of the AC contactor usually occurs at the terminal blocks of the contactor. These terminals are divided into two groups: one group is used to connect the power line, and the other group is used to connect the load line. The power terminal is used to connect the three-phase power supply and possible neutral line or ground line, and the load terminal is used to connect the motor or other loads. Currently, most of the connecting wires are connected by threading, but the connecting wires are not limited after connection, and are easy to fall off due to pulling or unstable connection. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an AC contactor connection structure.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an AC contactor connection structure, comprising an AC contactor body, a mounting seat is arranged on the AC contactor body, a limiting structure is arranged on the mounting seat, the limiting structure is mainly composed of six first slide grooves, the six first slide grooves are respectively opened on the mounting seat, two slide rods are slidably connected in the first slide grooves, a clamping block is fixedly connected to the slide rod, and a rubber pad is fixedly connected to the clamping block.

[0006] By adopting the above technical solution, after the connecting wires on the AC contactor body are connected, the two sliding rods are slid so that the two clamping blocks clamp the connecting wires, thereby limiting the connecting wires. The rubber pad can prevent the rigid contact between the clamping block and the connecting wires from causing damage to the connecting wires, and can also increase the friction between the clamping block and the connecting wires to improve the clamping effect.

[0007] The utility model is further configured as follows: first springs are fixedly connected to inner walls on both sides of the first sliding groove, and one end of the first spring is fixedly connected to the sliding rod.

[0008] By adopting the above technical solution, when the two clamping blocks clamp the connecting wire, the first spring is in a contracted state, so the rebound elastic force of the first spring acts on the sliding rod, which can enhance the limiting effect on the connecting wire.

[0009] The utility model is further configured as follows: six second sliding grooves are opened on the mounting seat, two pushing rods are slidably connected in the second sliding grooves, a bidirectional screw is rotatably connected to the second sliding grooves, the bidirectional screw is threadedly connected to the two pushing rods, the two sections of threads on the bidirectional screw are in opposite directions, and the three bidirectional screws located on one side are fixedly connected together.

[0010] The utility model is further configured as follows: one side of the mounting seat is rotatably connected to two cranks, and the two cranks are fixedly connected to the bidirectional screw.

[0011] By adopting the above technical solution, since the push rod slides in the second sliding groove, rotating the bidirectional screw can drive the two push rods to move closer to or away from each other, and then push the sliding rods closer to each other, making the clamping more stable. Since the three bidirectional screws are fixedly connected together, the bidirectional screws can be driven to rotate by turning the crank handle to further clamp the three connecting lines on one side, making the operation more convenient.

[0012] The utility model is further configured as follows: a mounting structure is arranged on the mounting seat, the mounting structure is mainly composed of a mounting groove, the mounting groove is arranged on the mounting seat, and the size of the mounting groove is adapted to the AC contactor body.

[0013] The utility model is further configured as follows: two connecting grooves are respectively provided on both sides of the AC contactor body, two limiting rods are respectively slidably inserted on both sides of the mounting seat, and the connecting grooves are adapted to the limiting rods in size.

[0014] The utility model is further configured as follows: telescopic rods are fixedly connected to both sides of the mounting seat respectively, one end of the telescopic rod is fixedly connected to a connecting rod, and the connecting rod is fixedly connected to the two limiting rods.

[0015] The utility model is further configured as follows: a second spring is sleeved on the telescopic rod, one end of the second spring is fixedly connected to the connecting rod, and the other end of the second spring is fixedly connected to the mounting seat.

[0016] By adopting the above technical solution, the connecting rod is pulled to drive the telescopic rod to stretch. At this time, the second spring is in a stretched state, and then the AC contactor body is inserted into the mounting groove. The connecting rod is loosened, and the connecting rod approaches the mounting seat under the action of the rebound force of the second spring, so that the four limit rods are inserted into the corresponding connecting grooves, and the AC contactor body and the mounting seat can be quickly installed together.

[0017] By adopting the above technical scheme, after the connecting wires on the AC contactor body are connected, the two sliding rods are slid so that the two clamping blocks clamp the connecting wires, thereby limiting the connecting wires, and the rubber pad can prevent the rigid contact between the clamping blocks and the connecting wires from causing damage to the connecting wires, and can also increase the friction between the clamping blocks and the connecting wires to improve the clamping effect. When the two clamping blocks clamp the connecting wires, the first spring is in a contracted state, so the rebound elastic force of the first spring acts on the sliding rod, which can enhance the limiting effect of the connecting wires. Since the push rod slides in the second slide groove, the rotation of the bidirectional screw rod can drive the two push rods to approach or move away from each other, thereby pushing the sliding rods to approach each other, making the clamping more stable. Since the three bidirectional screw rods are fixedly connected together, the bidirectional screw rods can be driven to rotate by turning the crank to further clamp the three connecting wires on one side, which is more convenient to operate, thereby avoiding the situation that most of the current connecting wires are connected by threading, but the connecting wires after connection are not limited, and are easy to fall off due to pulling or unstable connection.
