Description

Technical Field

[0001] The utility model relates to the technical field of AC motors, and particularly relates to a terminal block for an AC motor. Background Art

[0002] An AC motor is a machine used to realize the mutual conversion of mechanical energy and AC electrical energy. Due to the huge development of the AC power system, AC motors have become the most commonly used motors. Compared with DC motors, AC motors have a simpler structure, are easier to manufacture, are more robust, and are easier to make into motors with high speed, high voltage, large current, and large capacity because they do not have a commutator (see the commutation of DC motors). A terminal block is a common electrical connection component on an AC motor and is generally used to connect the power connection end of the motor to the power cord.

[0003] The current terminal block does not have the function of clamping the power cord. Most of them fix the power cord on the terminal post to complete the wiring operation. However, during use, it is easily pulled by external forces, resulting in the connection of the power cord being easily loosened and falling off, causing the operation of the AC motor to be interrupted, thus affecting the normal use of the AC motor.

[0027] The present utility model provides an AC motor terminal block as shown in Figure 1 and Figure 2 and includes:

[0028] The terminal block main body, the terminal block main body includes a base plate 1, a terminal 2, a lower fixing piece 3, a sleeve 5 and an upper fixing piece 6. The terminal 2 is connected to the upper end surface of the base plate 1 and is used to connect with the connection end of the power line. The lower fixing piece 3, the sleeve 5 and the upper fixing piece 6 are arranged outside the terminal 2. The sleeve 5 and the upper fixing piece 6 are arranged above the lower fixing piece 3. The sleeve 5 is connected to the upper end surface of the upper fixing piece 6. A wire clamping structure 4 is arranged on one side of the terminal 2. An installation screw groove 8 is opened on the upper end surface of the base plate 1. An installation screw 9 is threadedly connected inside the installation screw groove 8, and the terminal block can be installed on the AC motor.

[0029] The present utility model provides an AC motor terminal block as shown in Figure 3 and Figure 4An AC motor terminal block as shown, the wire clamping structure 4 includes a wire fixing block 41, a wire groove 42, a rod groove 43, a spring 44, a connecting rod 45, a clamping block 46, a groove 47, and a pull rod 48. The wire fixing block 41 is fixedly connected to the upper end surface of the bottom plate 1 through a round block. The wire groove 42 is opened on the wire fixing block 41. The rod groove 43 is opened inside the wire fixing block 41. The spring 44 is connected inside the rod groove 43. The connecting rod 45 is inserted into the rod groove 43. The clamping block 46 is arranged inside the wire groove 42.

[0030] The groove 47 is opened on the outer wall of the wire fixing block 41. The pull rod 48 is inserted into the groove 47, and one end of the pull rod 48 is connected to the outer wall of the connecting rod 45.

[0031] The rod groove 43 is arranged outside the wire groove 42. The free end of the spring 44 is connected to the connecting rod 45. The end of the connecting rod 45 away from the spring 44 is connected to the clamping block 46.

[0032] Through the above technical solutions:

[0033] When wiring, first manually pull the pull rod 48 to adjust the distance between the two clamping blocks 46 to the maximum. Then, pass the connection end of the power cord through the wire groove 42. After the connection end is connected to the terminal 2, release the pull rod 48. The clamping block 46 clamps the outside of the power cord segment. This operation can fix the power cord, ensuring the stability of the power cord connection after connection, avoiding the situation that the connection loosens due to accidental external pulling and causing detachment, ensuring the wiring effect of the terminal block. In addition, it can also make the terminal block have an anti-pulling function, so that the connection of the power cord is not affected by the pulling force, ensuring the normal use of the AC motor.

[0034] The present utility model provides an AC motor terminal block as shown Figure 5 On the other side of the terminal 2, there is an adjusting structure 7. The adjusting structure 7 includes a fixing plate 71, a plate groove 72, a movable connecting plate 73, a connecting shaft 74, a gear 75, a plurality of racks 76, and a convex block 77.

[0035] The fixing plate 71 is fixedly connected to the upper end surface of the bottom plate 1. The plate groove 72 is opened inside the fixing plate 71. The movable connecting plate 73 is inserted into the plate groove 72, and the end of the movable connecting plate 73 away from the fixing plate 71 is connected to the sleeve 5.

[0036] The connecting shaft 74 is movably connected in a placement groove formed in the inner wall of the fixed plate 71. The gear 75 is installed on the outside of the connecting shaft 74. A plurality of racks 76 are connected to one side of the outer surface wall of the movable connecting plate 73 at equal intervals and evenly. The convex block 77 is provided on the outside of the fixed plate 71. One end of the connecting shaft 74 is connected to the convex block 77. The other side of the outer surface wall of the movable connecting plate 73 is connected with a slider 78. A sliding groove 79 is formed in the inner wall of the fixed plate 71 outside the slider 78. When the movable connecting plate 73 moves up and down, the slider 78 slides in the sliding groove 79, ensuring the stability of the up and down movement of the movable connecting plate 73.

[0037] Through the above technical solution:

[0038] After the connection end of the power cord is connected to the terminal 2, first take a tool and insert one end of it into the slot formed in the convex block 77. Then rotate the tool to drive the connecting shaft 74 to rotate. The gear 75 rotates as the connecting shaft 74 rotates. At this time, the gear 75 meshes with the rack 76, causing the movable connecting plate 73 to descend, so that the upper fixing piece 6 connected through the sleeve 5 descends until the fixing is completed. This operation can quickly realize the fixing of the connecting wire to the terminal 2. The operation is simple and convenient, solving the problem that the existing method of fixing by screwing the nut easily causes the thread to slip and jam during the screwing process, resulting in incomplete fixing, ensuring the firmness of the connection between the power cord and the terminal 2. In addition, it also avoids the drawback of having to remove and replace the nut due to thread slippage, improving the convenience of connection and fixing.
