Description
Technical Field
The invention relates to the field of lightning protection equipment, in particular to a surge protector.
Background
The tripping mechanism and the tripping monitoring or indicating of the surge protector are necessary mechanisms for the safe operation of the surge protector, the current tripping mechanism mostly adopts a hot melt tripping mode, and mainly comprises a push-off type mechanism and a cut-off type mechanism, and the representative mechanisms are respectively shown in fig. 1 and 2. The principle is that when the surge protector fails to generate heat, the low-temperature welding of the electrode connecting points in the figure melts, so that the contact electrodes are separated, and the purpose of tripping is achieved.
The push-off mechanism of fig. 1 mainly comprises a surge protector (namely a surge protector) connecting electrode a, a push-off sheet B and a spring F, wherein during the production of the surge protector, an L electrode point of a piezoresistor and the surge protector connecting electrode a are welded by adopting low-temperature soldering tin, and the push-off sheet B pushes the surge protector connecting electrode a under the action of the force of the spring F. When the piezoresistor heats up due to failure, the soldering tin on the electrode point L melts, the push-off piece B rotates around the point O, and the push-off piece B pushes away the connecting electrode A of the surge protector.
The cut-off mechanism of fig. 2 mainly comprises a surge protector connecting electrode a, a cut-off sheet B and springs F1 and F2, wherein the L electrode point of the piezoresistor and the surge protector connecting electrode a are welded by adopting low-temperature soldering tin, and the cut-off sheet B is extruded between the surge protector connecting electrode a and the L welding point of the piezoresistor under the action of the forces of the springs F1 and F2. When the piezoresistor generates heat due to failure, the soldering tin on the L electrode point is melted, and the blocking sheet B cuts off the soldering tin between the connecting electrode A of the surge protector and the L welding point of the piezoresistor and isolates and blocks the soldering tin under the pulling of F1/F2.
But both the push-off mechanism of fig. 1 and the trip mechanism of fig. 2 have instances of trip failure in actual use and experimentation. The reason is that the trip mechanism of fig. 1 has insufficient release amplitude and occasional stringing of the solder material, which makes the distance between the electrode of the surge protector and the varistor electrode pad insufficient, thereby creating an arc discharge. The interrupter mechanism of fig. 2 employs a larger area of the interrupter in order to stabilize the mechanism operation, but when the piezoresistors are warmed up, the interrupter is deflected, and meanwhile, due to the thickness limitation of the spacers in the process implementation, the breakdown phenomenon exists.

In order that the invention may be understood more fully, the invention will be described with reference to the accompanying drawings.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to and integrated with the other element or intervening elements may also be present. The terms "mounted," "one end," "the other end," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
The tripping mechanism of the embodiment of the invention can be applied to an electronic device needing tripping protection, and the device to be tripped and protected is provided with an electrode connecting point, an electrode connecting piece and a tact switch. The electrode connecting piece is welded on the electrode connecting point through soldering tin, and the electrode connecting point and the tact switch are both arranged on the tripping mechanism.
The protection device to be tripped may be a surge protector of the present embodiment, as shown in fig. 3, which includes a connection electrode 22 and a varistor, and is provided with the tripping mechanism described above. The electrode connection point corresponds to an electrode point 21 of a piezoresistor in the surge protector, the electrode connection piece corresponds to a connection electrode 22 of the surge protector and a soft copper strip 24 connected with the connection electrode 22, the tact switch corresponds to a monitoring tact switch 23 of the surge protector, and the electrode point 21 is welded on the connection electrode 22 through soldering tin. In this embodiment, the function of the monitoring tact switch 23 is to monitor the working state of the surge protector, and when the monitoring tact switch 23 is closed, it indicates that the surge protector is in a protection state (i.e. a normal working state), and when the monitoring tact switch 23 is opened, it indicates that the surge protector is in an open state.
The tripping mechanism of the embodiment mainly comprises a base 1, a first shaft 2, a push-off sheet 3, a traction piece 4, a shielding sheet 5, a second shaft 6 and a blocking point 7. One end of the push-off piece 3 is rotatably mounted on the base 1, for example, one end of the push-off piece 3 is rotatably mounted on the base 1 through a first shaft 2, and the first shaft 2 can be a pin, a screw, a bolt or the like. The other end of the push-off sheet 3 is pushed down on the connection electrode 22 by the traction of the traction member 4, providing a push-off force of the connection electrode 22 against the electrode point 21. The end of the connection electrode 22 remote from the electrode point 21 is rotatably connected, and the connection electrode 22 can be connected to one L-pin of the surge protector by a flexible copper strip 24. Referring to fig. 5, when the solder on the electrode point 21 melts, the connection electrode 22 and the electrode point 21 are in a loose state, so that the pushing piece 3 pressed down on the connection electrode 22 pushes the connection electrode 22 away from the electrode point 21. The electrode point 21 may be fixed to the base 1 or other components according to the installation environment of the surge protector, as long as the use of the trip mechanism of the present embodiment is not affected.
The pushing-off piece 3 can be in a herringbone shape, one leg of the herringbone shape is rotatably arranged on the base 1, the other leg of the herringbone shape is pressed down on the connecting electrode 22, and one leg pressed on the connecting electrode 22 has a contact plane and contact angles positioned on two sides of the contact plane. The head of the Y-shaped is pulled by the pulling member 4.
The traction member 4 may be an elastic member or a non-elastic member, and when it is a non-elastic member, external traction force needs to be introduced, and the introduction mode is not limited, so long as it can finally act to pull the push-off sheet 3. The pulling element 4 is preferably an elastic element, such as a spring, so that both ends of the elastic element can be fixed, and when fixed, the elastic element generates a deformation force due to stretching, and the deformation force can be used as the pulling force of the whole tripping mechanism.
The shielding sheet 5 is rotatably mounted on the push away sheet 3, for example, the shielding sheet 5 is rotatably mounted on the push away sheet 3 through a second shaft 6, and the second shaft 6 can also adopt pins, screws, bolts and the like, in this embodiment, the shielding sheet 5 is rotatably mounted at the junction of two legs of the herringbone shape. The blocking point 7 is fixed to the base 1. The first end of the shutter 5 is pressed down on the monitoring tact switch 23 by a blocking force on the blocking point 7 at the opposite end (second end). The monitoring tact switch 23 may be fixed on the base 1 or other components according to the installation environment of the surge protector, as long as the use of the trip mechanism of the present embodiment is not affected. The first end of the shielding 5 also extends between the electrode point 21 and the connection electrode 22 and to the same side of the electrode point 21 as the connection electrode 22. In this embodiment, the first end of the shielding plate 5 extends between the electrode point 21 and the connection electrode 22 and extends to the same side of the electrode point 21 and the connection electrode 22, the second end of the shielding plate 5 abuts against the blocking point 7, and the blocking point 7 is used for applying a blocking force for rotating the first end of the shielding plate 5 between the electrode point 21 and the connection electrode 22 to the shielding plate 5. The rotation here is performed only when the electrode point 21 is separated from the connection electrode 22, and when the electrode point 21 is not separated from the connection electrode 22, the blocking force only tends to rotate the shutter 5.
When the solder on the electrode point 21 melts, the push-off piece 3 pushed down on the connecting electrode 22 moves down by the continuous pulling of the pulling member 4, and the shielding piece 5 is pulled to move along with the continuous pushing down. However, the shielding 5 is blocked by the presence of the blocking point 7, which results in the shielding 5 rotating about the axis two 6. In this way, the second end of the shielding plate 5 is blocked by the blocking point 7, so that the first end rotates towards the direction approaching the connection electrode 22 and between the electrode point 21 and the connection electrode 22, and simultaneously the monitoring tact switch 23 is released, the monitoring tact switch 23 is disconnected, and the shielding plate 5 is suspended on the monitoring tact switch 23.
The end of the shielding sheet 5 pressed down on the monitoring tact switch 23 is in the form of a hook, that is, the first end of the shielding sheet 5 is in the form of a hook, and the pointed part of the hook extends to the same side of the electrode point 21 and the connecting electrode 22. By the shape design, when the blocking piece 5 of the tripping mechanism is directly inserted between the electrode point 21 and the connecting electrode 22, the soldering wire between the electrode point 21 and the connecting electrode 22 can be conveniently and quickly cut off, and the arc between the electrode point 21 and the connecting electrode 22 can be quickly blocked.
When the surge protector is operating normally and the solder on the electrode point 21 is not melted, the inference piece 3 presses against a contact angle of one leg of the connection electrode 22 to contact with the connection electrode 22. When the soldering tin on the electrode point 21 melts, the pushing-off piece 3 continuously presses down the connecting electrode 22 through the traction of the traction piece 4, and when one leg pressed on the connecting electrode 22 rotates to the state of fig. 4, the contact surface of the pushing-off piece forms surface contact with the connecting electrode 22, so that the contact surface can still effectively push the connecting electrode 22 even if the contact angle part of the pushing-off piece 3 is deformed due to heating, and finally the connecting electrode 22 is pushed away from the electrode point 21, and meanwhile, the shielding piece 5 is pulled; at this time, the other contact angle pressed against one leg of the connection electrode 22 is in contact with the connection electrode 22. One end of the shielding plate 5 is rotated by the blocking force of the blocking point 7 in a direction approaching the connection electrode 22 and is rotated between the electrode point 21 and the connection electrode 22, and is suspended on the monitoring tact switch 23.
The surge protector has an off state in which the electrode point 21 is separated from the connection electrode 22, and the first end of the blocking plate 5 is located between the electrode point 21 and the connection electrode 22 with gaps between the electrode point 21 and the connection electrode 22. In general, when the first end of the blocking sheet 5 is inserted between the electrode point 21 and the connection electrode 22, a gap of 2mm or more is provided between the electrode point 21 and the connection electrode 22.
When the surge protector is in a protection state (namely a normal working state), the tripping mechanism is not tripped and is in a locking state, at the moment, the blocking sheet 5 presses the monitoring tact switch 23 to enable the monitoring tact switch 23 to be closed, and at the moment, a circuit matched with the monitoring tact switch 23 is in a conducting state, so that the surge protector can be indicated to be in the normal working state. When the surge protector is in an off state due to excessive current, the blocking sheet 5 rotates and releases the monitoring tact switch 23 to enable the monitoring tact switch 23 to be turned off, and a circuit matched with the monitoring tact switch 23 is in an off state at the moment, so that the surge protector can be externally indicated to be in the off state.
When the surge protector is manufactured, the tripping mechanism is at rest in the position shown in fig. 3, the electrode points 21 of the piezoresistors are welded with the connecting electrodes 22 of the surge protector by low-temperature soldering tin, and the blocking sheet 5 presses down the monitoring tact switch 23 to enable the monitoring tact switch 23 to be in a closed state. When the varistor heats up due to failure, the solder on the electrode point 21 melts, the push-off piece 3 rotates clockwise around the first axis 2 under the force of the spring, the upper end of the shielding piece 5 rotates anticlockwise around the second axis 6 due to the blocking effect of the blocking point 7, the release effect of the shielding piece 5 is as shown in fig. 5, the push-off piece 3 pushes the connecting electrode 22 of the surge protector away from the electrode point 21 of the varistor, and meanwhile, the shielding piece 5 is inserted between the connecting electrode 22 of the surge protector and the electrode point 21 of the varistor. The monitoring tact switch 23 returns to the off state.
The push-off action of the tripping mechanism of the invention enables the electrode point 21 of the piezoresistor and the connecting electrode 22 of the surge protector to have a larger space distance, and in the implementation scheme, the space distance is larger than the electrode safety distance of 6 mm. The blocking piece 5 of the mechanism is directly inserted between the electrode point 21 of the piezoresistor and the connecting electrode 22 of the surge protector, cuts off the soldering wire between the electrode point 21 and the connecting electrode 22, and blocks the arc between the electrode point 21 and the connecting electrode 22.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples merely represent a few embodiments of the invention, which are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
