[0001] The utility model relates to the technical field of switch assembly, in particular to power line switch assembly equipment. Background Art

[0002] Air switch, also known as air circuit breaker, is a type of circuit breaker. It is a switch that automatically disconnects as long as the current in the circuit exceeds the rated current. Air switch is a very important electrical appliance in low-voltage power distribution network and electric traction system, which integrates control and multiple protection functions. In addition to completing contact and disconnection of circuits, it can also protect circuits or electrical equipment from short circuits, severe overloads and undervoltages, and can also be used to start motors infrequently. The air switch is located between the power line and the equipment, and can provide certain overload protection for the equipment.

[0003] The current way to connect the device to the switch line is to open its top cover, remove the outer jacket at one end of the line to expose the wire inside, then pass the wire through the semi-arc groove at the bottom base of the device, and insert it between the conductive plates connected with screws, then tighten the screws and cover the top cover. It is not difficult to see from the above that the installation of the entire power cord requires many steps and is inconvenient to install. Utility Model Content

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The utility model provides a support plate inside the switch housing, and installs a fixing rod above the support plate. When assembling the power cord switch, the power cord is inserted into a connecting hole 1, so that the conductive end of the power cord falls into the semi-arc groove of the support plate, and then the fixing rod is pressed down to make the pressure plate fall on the surface of the power cord for fixing. When the fixing rod moves down, the spherical block on the surface of the fixing rod is clamped under the limit plate, and the connecting rod at the bottom of the fixing rod is clamped with the lower inclined plate through the upper inclined plate to fix the fixing rod, so as to avoid the fixing rod moving and causing the pressure plate to be separated from the power cord, simplify the overall assembly operation of the power cord, and improve the assembly efficiency of the power cord switch.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-4, including a switch housing 1, on the surface of which a switch handle 2 is installed. A connection hole 1 3 is provided on the outer wall of the switch housing 1; a support plate 4 is provided inside the switch housing 1, and the support plate 4 is close to the connection hole 1 3, and a semi-arc groove is provided on the top of the support plate 4. When the power cord is inserted into the switch housing 1 from the connection hole 1 3, the conductive position of the power cord will fall into the semi-arc groove of the support plate 4; a connection hole 2 9 is provided on the outer wall of the switch housing 1, and vertically corresponds to the support plate 4; a fixing rod 10 is provided inside the connection hole 2 9, and a guide block is fixed on the outer wall close to one end of the connection hole 2 9, and a guide groove is provided on the inner wall of the connection hole 2 9 at a position corresponding to the guide block. The guide block moves in the guide groove to prevent the fixing rod 10 from deflecting. One end of the bottom of the fixing rod 10 falls into the semi-arc groove provided on the support plate 4. When the power cord is installed in the support plate 4, the power cord is fixed by pressing down the fixing rod 10. The limit plate 11 is fixed on the inner wall of the switch housing 1. The limit plate 11 is made of elastic material. A movable hole is opened on the surface of the limit plate 11 corresponding to the position of the fixed rod 10, and an expansion groove is opened on the outer circle of the surface of the limit plate 11; the sealing plug 12 is sleeved on the outer wall of the fixed rod 10 near the end of the connecting hole 29. When the fixed rod 10 is pressed down, the sealing plug 12 will be blocked inside the connecting hole 29, which can not only reduce the dust from entering the switch housing 1 from the connecting hole 29, but also can fix the position of the fixed rod 10 through the mutual compression of the sealing plug 12 and the connecting hole 29; the spherical block 13 is fixed on the outer wall of the fixed rod 10. When the fixed rod 10 presses the power cord, the spherical block 13 moves from the fixed rod 10 as the fixed rod 10 moves downward. The spherical block 13 passes through the movable hole opened by the limiting plate 11, and due to the limitation of the size of the movable hole, when the spherical block 13 passes through the movable hole, the interior of the limiting plate 11 is recessed downward until the spherical block 13 completely passes through the movable hole, and the limiting plate 11 returns to its original position through elastic force. At this time, the limiting plate 11 is located above the spherical block 13, further limiting the position of the fixing rod 10 to ensure that the fixing rod 10 can fix the power cord and the switch. When the power cord needs to be repaired or replaced, the fixing rod 10 is pulled upward to make the spherical block 13 pass through the movable hole of the limiting plate 11 and move to the top of the limiting plate 11. At this time, the bottom of the fixing rod 10 is detached from the power cord, so that the power cord can be easily pulled out from the inside of the connecting hole 3.

[0029] The top of both sides of the support plate 4 is provided with a limiting groove 5, and a lower inclined plate 6 is fixed to the inner wall of the limiting groove 5 on one side close to the connecting hole 1 3. A movable plate 7 is installed on the side of the inner wall of the limiting groove 5 away from the lower inclined plate 6, and a guide groove is provided on the inner wall of the limiting groove 5 corresponding to the position of the movable plate 7, and one end of the movable plate 7 is installed in the guide groove. A compression spring 1 8 is fixed to the side of the movable plate 7 away from the lower inclined plate 6, and a mounting groove is provided on the inner wall of the limiting groove 5 corresponding to the position of the compression spring 1 8, and one end of the compression spring 1 8 away from the movable plate 7 is installed in the mounting groove. By applying pressure to the compression spring 1 8, the movable plate 7 can be moved within a certain range.

[0030] The end of the fixing rod 10 close to the supporting plate 4 is fixed with a pressing plate 14, and the surface of the pressing plate 14 on the side away from the fixing rod 10 is provided with an anti-skid groove. When the pressing plate 14 is pressed on the surface of the power line, the friction between the pressing plate 14 and the power line can be increased through the anti-skid groove. Support rods are fixed at the positions corresponding to the limit grooves 5 on both sides of the pressing plate 14, and a connecting rod 15 is connected through the support rod. An upper inclined plate 16 is fixed on the side of the connecting rod 15 close to the lower inclined plate 6. When the fixing rod 10 moves downward, the connecting rod 15 is inserted into the limiting groove 5, and the movable plate 7 is squeezed by the connecting rod 15 and moves to the side away from the lower inclined plate 6. The upper inclined plate 16 engages with the lower inclined plate 6 as the connecting rod 15 moves downward. At this time, the fixing rod 10 is restricted by the limiting plate 11, and is also restricted by the upper inclined plate 16 and the lower inclined plate 6, so as to achieve the purpose of stabilizing the fixing rod 10, prevent the fixing rod 10 from moving, and make the power line separate from the pressing plate 14.

[0031] Mounting holes are provided on both sides of the connection hole 13, and movable rods 17 are installed inside the mounting holes. Through holes are also provided at positions corresponding to the mounting holes on the side walls of the support plate 4, and the through holes are located above the lower inclined plate 6. The ends of the movable rods 17 pass through the through holes of the support plate 4 and are located inside the limiting grooves 5. A connecting plate 18 is fixed to one end of the two sets of movable rods 17 away from the switch housing 1. A compression spring 19 is provided on the outer surface of the movable rod 17, and the compression spring 19 is located between the switch housing 1 and the connecting plate 18. When the power cord or the switch needs to be repaired separately, the movable rod 1 7 pushes toward the support plate 4 through the connecting plate 18, so that the end of the movable rod 17 pushes the connecting rod 15 to move toward the movable plate 7. When the connecting rod 15 moves, the upper inclined plate 16 is disjointed from the lower inclined plate 6, and the fixed rod 10 is pulled upward to make the connecting rod 15 disengage from the inside of the limiting groove 5, so that the pressing plate 14 is separated from the power cord, and the power cord can be normally pulled out from the connecting hole 1 3. After loosening the connecting plate 18, the connecting plate 18 automatically moves in the direction away from the switch housing 1 through the thrust of the compression spring 2 19, so as to avoid the connecting rod 15 encountering obstacles when it is inserted next time.

[0032] Working principle: when installing the power cord switch, insert the conductive connection end of the power cord from the connection hole 1 3 into the switch housing 1, so that the conductive connection end falls into the semi-arc groove of the support plate 4, and then press the fixing rod 10 toward the switch housing 1. When the fixing rod 10 moves downward, it moves along the guide groove opened in the connection hole 2 9 to prevent the connecting rod 15 from deviating from the limiting groove 5. When the fixing rod 10 moves downward, the spherical block 13 passes through the movable hole opened in the limiting plate 11, and the connecting rod 15 falls into the limiting groove 5. The upper inclined plate 16 fixed on the side wall of the connecting rod 15 overlaps with the lower inclined plate 6, and the pressure plate 14 at the bottom of the fixing rod 10 is completely pressed on the conductive connection end of the power cord. When the surface is moved, the surface of the fixing rod 10 is sleeved on the sealing plug 12 and blocked in the connecting hole 29, reducing the possibility of dust and impurities entering the switch housing 1 from the connecting hole 29. The spherical block 13 fixed on the outer wall of the fixing rod 10 moves to the bottom of the limiting plate 11 to preliminarily fix the position of the fixing rod 10. The connecting rods 15 on both sides of the pressure plate 14 fall into the limiting groove 5. The connecting rods 15 are pushed by the movable plate 7, and the upper inclined plate 16 overlaps and engages with the lower inclined plate 6, thereby avoiding the possibility of the fixing rod 10 moving up, so that the pressing plate 14 is firmly pressed above the power cord, and the power cord is fixed by pressing down the fixing rod 10, which simplifies the assembly operation of the power cord and improves the efficiency of special assembly.

[0033] When the power cord or switch needs to be inspected separately, the connecting plate 18 can be pushed toward the switch housing 1 so that the end of the movable rod 17 pushes the connecting rod 15, and the connecting rod 15 moves away from the lower inclined plate 6, thereby misaligning the upper inclined plate 16 and the lower inclined plate 6, releasing the clamping state, and then the fixing rod 10 is pulled upward to disengage the connecting rod 15 from the limiting groove 5. The spherical block 13 also moves up to the top of the limiting plate 11 with the movement of the fixing rod 10. After the fixing rod 10 moves upward, the pressing plate 14 is lifted accordingly, and the distance between the semi-arc groove of the pressing plate 14 and the support plate 4 increases, so that the power cord in the semi-arc groove can be easily disengaged, which is convenient for the inspection and replacement of the power cord or switch.
