The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The embodiment of the application provides a wiring terminal, which is used for connecting a lead, wherein fig. 1 is a schematic overall structure diagram of the wiring terminal provided by the embodiment of the application, fig. 2 is a sectional view of the wiring terminal in a state that the lead is not connected, and fig. 3 is a sectional view of the wiring terminal in a state that the lead is connected, and as shown in fig. 1, fig. 2 and fig. 3, the wiring terminal comprises a wiring board 1, a positioning shaft 2, a wire pressing plate 3, a pushing piece 4 and a fixing piece 5; the pushing piece 4 and the fixing piece 5 are positioned on one side of the positioning shaft 2, and the pushing piece 4 is connected to the fixing piece 5; the wiring board 1 is positioned at the other side of the positioning shaft 2; the middle part of the wire pressing plate 3 is abutted against the positioning shaft 2, the first end 31 of the wire pressing plate 3 is positioned between the pushing piece 4 and the fixing piece 5, and the second end 32 of the wire pressing plate 3 is positioned on the side of the wiring board 1; the pushing member 4 pushes the first end 31 when approaching the fixing member 5, so that the wire pressing plate 3 rotates around the positioning shaft 2, and the second end 32 approaches the wiring board 1 to press the wires 10 against the wiring board 1.

The wiring board 1 is used for electrical connection with the accessed wires 10, so the wiring board 1 has the property of conducting electricity, one object to be electrically connected is connected with the wiring board 1, and the other object to be electrically connected is connected with the wires 10, so when the second end 32 of the wire pressing plate 3 presses the wires 10 against the wiring board 1, the wires 10 and the wiring board 1 are directly electrically connected, and the two objects to be electrically connected are indirectly electrically connected. For example, when one object to be electrically connected is a main circuit of a circuit breaker and the other object to be electrically connected is a load, the terminal block 1 is fixed in the circuit breaker and connected to the main circuit of the circuit breaker, the load is connected to the wire 10, and when the second end 32 of the tension disc 3 presses the wire 10 against the terminal block 1, the load is switched into the main circuit of the circuit breaker.

Location axle 2 can be fixed in the device that uses this binding post, and it can be arbitrary axle class structure, and location axle 2 can only be as line ball board 3's fulcrum, also can play other effects simultaneously, and this application does not limit to location axle 2's fixed mode and other effects.

The technical scheme of the application can be understood by utilizing the lever principle: the middle part of the wire pressing plate 3 is abutted against the positioning shaft 2, the wire pressing plate 3 is equivalent to a lever, the positioning shaft 2 is equivalent to a fulcrum for abutting of the lever, and the middle part of the wire pressing plate 3 is any position except two end parts of the wire pressing plate 3. When the pushing member 4 approaches the fixing member 5 and pushes against the first end 31 of the wire pressing plate 3, which is equivalent to one end of the lever being stressed, the wire pressing plate 3 necessarily rotates around the fulcrum (the positioning shaft 2), that is, the second end 32 of the wire pressing plate 3 necessarily moves along a track similar to a circumference, when the wiring board 1 is located on the moving track of the second end 32, the wire 10 is placed between the wiring board 1 and the second end 32, and along with the movement of the second end 32, the wire 10 is necessarily pressed against the wire 10 at a certain moment, so that the wire 10 is pressed against the wiring board 1, and at this moment, as long as the wire pressing plate 3 is fixed at this position, the wire 10 can be stably pressed against the wiring board 1 by the wire pressing plate 3, and stable connection between the wire 10 and the wiring board 1 is realized. If the lead 10 needs to be loosened, the wire pressing plate 3 only needs to be moved in the opposite direction.

The tension disc 3 is used as a component for applying a resisting force to the lead 10, and the embodiment of the application does not require any special requirements on the material, shape, size and the like of the tension disc 3 as long as the lead 10 can be pressed through the actions in the scheme. The wire pressing plate 3 is not necessarily flat, and may be long, or may be bent in any direction, and since the wire pressing plate 3 may be bent in any direction, the first end 31 and the second end 32 of the wire pressing plate 3 do not have a necessary relative position relationship, because no matter where the first end 31 and the second end 32 of the wire pressing plate 3 are located, the first end 31 is forced to necessarily drive the second end 32 to move, as long as the pushing member 4 is required to push the first end 31 when approaching the fixing member 5, and the second end 32 is caused to approach the wiring board 1 to press the wires 10 on the wiring board 1.

The pushing member 4 is connected to the fixing member 5, so that a connection portion is inevitably formed between the pushing member 4 and the fixing member 5, and in some embodiments, a threaded rod is connected to the pushing member 4, extends to the fixing member 5, and is in threaded connection with the fixing member 5, and the pushing member 4 can be moved closer to or away from the fixing member 5 by rotating the threaded rod, so as to push the first end 31 to move. In other embodiments, connect the polished rod on the top pushes away piece 4, set up the jack on the mounting 5, the polished rod can be arbitrary shape, as long as the polished rod can extend to mounting 5, and peg graft with mounting 5 can, can set up the arch that is used for the joint on the jack inner wall, also can set up some archs on the polished rod, so when promoting top pushes away piece 4, top pushes away piece 4 and drives the polished rod and remove in the jack, protruding and the jack in the arch on the polished rod is in the mutual joint of different positions, thereby fix a position the polished rod, and then fix a position top pushes away piece 4.

As can be seen from the above analysis, the connecting portion between the pushing member 4 and the fixing member 5 does not have more functions, and therefore, the size of the connecting portion is not limited, and the size of the connecting portion can be set to be small, and the first end 31 of the wire pressing plate 3 is also set between the pushing member 4 and the fixing member 5, so that the space between the pushing member 4 and the fixing plate can be used for accommodating the portion where the pushing member 4 is connected with the fixing member 5, and can also be used for allowing the first end 31 of the wire pressing plate 3 to rotate, and thus the space can be fully utilized.

As shown in fig. 2 and 3, in some embodiments, the terminal further includes a bolt, the fixing member 5 is provided with a screw hole, a screw rod of the bolt is connected in the screw hole, and the pushing member 4 is configured as a head of the bolt.

There will generally be certain diameter difference between the screw rod of bolt and the spiral shell head, this makes the spiral shell head be close to the terminal surface of screw rod one side just can be used for supporting the first end 31 of line ball board 3 of pushing, and because the bolt is the standard component, so need not special manufacture, the manufacturing cost of binding post is also lower relatively.

When using, only need twist the bolt, can make the whole direction that is close to mounting 5 of bolt move, thereby make the spiral shell head promote line ball board 3 and rotate, the operation is comparatively simple, and, because bolt and screw complex characteristic, no matter the bolt moves arbitrary position, all can realize the auto-lock in the axial, thereby make the spiral shell head with line ball board 3 location in specific position, so that make line ball board 3 keep supporting the state of pressing on wiring board 1 with wire 10, realize the stable connection between wire 10 and the wiring board 1.

As shown in fig. 1 and 4, in some embodiments, the first end 31 of the tension disc 3 is provided with an escape portion 6, and the escape portion 6 is used for escaping the screw during rotation of the tension disc 3.

Under the condition that do not establish dodging portion 6, in order to avoid the screw rod, the first end 31 of line ball board 3 can only set up in the screw rod and be close to one side of location axle 2, and at the in-process that the bolt was screwed in, the area that line ball board 3 can with the spiral shell head butt is less, and at the in-process of butt, also probably make line ball board 3 and spiral shell head break away from mutually because the skew of the deformation of line ball board 3 or position to can't realize cooperating between the part and compress tightly the purpose of wire 10.

Through setting up dodging portion 6, dodge portion 6 after avoiding the screw rod, can make the first end 31 of line ball board 3 further extend towards the space of screw rod periphery in to increase the area of the first end 31 of line ball board 3 and the first terminal surface butt of spiral shell, prevent to break away from with the spiral shell head at the rotation in-process of line ball board 3, simultaneously, dodge portion 6 set up and also can prevent that line ball board 3 from taking place to interfere with the screw rod at the rotation in-process.

As shown in fig. 4, in some embodiments, the relief 6 is configured as a notch in the tension disc 3, and the screw is at least partially located in the notch, and the notch has at least one dimension in a direction larger than the diameter of the screw and smaller than the diameter of the screw head.

The opening of the notch may be oriented in any direction, such as away from the second end 32. The degree of depth of breach can be greater than the diameter of screw rod, and the screw rod can block in the breach completely like this, and the width of breach can be greater than the diameter of screw rod and be less than the diameter of spiral shell head, and so, the range that the screw rod takes place to remove in the breach is less, is favorable to increasing binding post's structural stability.

The breach can be used for dodging the screw rod, simultaneously, when the at least part of screw rod is located the breach, the edge of breach can also be used for spacing line ball board 3 for line ball board 3 can't produce the displacement of great degree in the axis direction of perpendicular to screw rod, thereby makes the spiral shell head can support the position that is close to the breach at line ball board 3 all the time, so, line ball board 3's rotation direction is also relatively fixed, can not influence the butt effect to wire 10 owing to produce great skew at the rotation in-process.

In some embodiments, the escape portion 6 is configured as a through hole provided in the tension plate 3, and a screw rod is inserted into the through hole, and the through hole has at least one dimension larger than the diameter of the screw rod and smaller than the diameter of the screw head.

Line ball board 3 passes through the through-hole cover on the screw rod for the screw rod can only be at the through-hole activity, consequently, line ball board 3 can't produce the displacement of great degree on the axis direction of perpendicular to screw rod, thereby makes the spiral shell head can support the position that is close to the through-hole at line ball board 3 all the time, and so, line ball board 3's direction of rotation is also relatively fixed, can not influence the butt effect to wire 10 owing to produce great skew at the rotation in-process.

As shown in fig. 2, 3 and 4, in some embodiments, the wire pressing plate 3 includes a plurality of stacked elastic sheets 33, and an end of the elastic sheets 33 close to one end of the wiring board 1 has a gap and is disposed in a staggered manner, so that the elastic sheets 33 can respectively press the wires 10 against the wiring board 1 after the wire pressing plate 3 rotates.

The elastic sheet 33 is a component capable of generating obvious elastic deformation after being stressed, and the wire 10 is pressed through the elastic sheet 33, so that when the pressing force is too large, the elastic sheet 33 can deform, the force applied to the first end 31 of the elastic sheet 33 can not be completely transferred to the wire 10, and the phenomenon that the force applied to the first end 31 of the wire pressing plate 3 is too large to cause the second end 32 to damage the wire 10 is avoided.

Because the line pressing plate 3 is close to the lead 10 by rotating and presses the lead 10 against the wiring board 1, the elastic pieces 33 are basically not perpendicular to the lead 10, that is, when the elastic pieces 33 press against the lead 10, the included angle between the elastic pieces 33 and the lead 10 is not 90 degrees, if the multiple layers of elastic pieces 33 are not arranged in a staggered manner, only the end part of one elastic piece 33 positioned on the front side of the moving direction of the second end 32 can be directly contacted with the lead 10, and the rest elastic pieces 33 cannot be directly contacted with the lead 10, so that the pressed part of the lead 10 is only one, in this case, two problems may exist, one is that the force of the line pressing plate 3 pressing against the lead 10 is too large, the contact area between the line pressing plate 3 and the lead 10 is small, so that the pressure intensity is large, and the lead 10 is damaged by extrusion; secondly, the force of the wire pressing plate 3 pressing the wire 10 is too small, and the pressing part is only provided with one part, so that the pressing of the wire 10 is not firm enough, and the wire 10 is easy to loosen.

When the elastic sheet is provided with multiple layers, the lengths of the ends, close to the wiring board 1, of the multiple layers of elastic sheets 33 are different, and the lengths of the ends, close to the wiring board 1, of the multiple layers of elastic sheets 33 are shorter and the lengths of the ends, close to the wiring board 1, of the multiple layers of elastic sheets 33 are longer as the ends, close to the wiring board 1, of the multiple layers of elastic sheets 33 are farther. The length of the elastic sheet 33 near one end of the wiring board 1 refers to the distance from the position where the elastic sheet 33 abuts against the positioning shaft 2 to the end of the elastic sheet 33 near the wiring board 1.

The lengths of the elastic sheets 33 in the above layers are set in such a way that the second end of the elastic sheet 33 far away from the wiring board 1 is protruded from the second end of the elastic sheet 33 near the wiring board 1, thereby forming a dislocation. Thus, when the multi-layer elastic sheet 33 rotates to approach the wiring board 1 and abuts against the wires 10, the end of each elastic sheet 33 can be in direct contact with the wires 10 independently to form an independent pressing point, and the more the elastic sheets 33 are, the more the pressing points are, the tighter the wires 10 are attached to the wiring board 1, and the more the electrical connection between the wires 10 and the wiring board 1 is stable.

Wherein, multilayer shell fragment 33 can interconnect, perhaps need not to connect, when being connected between a plurality of shell fragments 33, a plurality of shell fragments 33 can only be first end 31 interconnect, and the connected mode can be joint, welding, clamping, buckle or bonding etc. this application embodiment does not limit to this, can understand that, when a plurality of shell fragments 33 interconnect, a plurality of shell fragments 33 can receive the butt of top pushing part 4 simultaneously and rotate, and the stability of whole structure is stronger.

As shown in fig. 2, 3 and 4, in some embodiments, the wire pressing plate 3 is provided with a positioning groove 9 in the middle, and the positioning groove 9 is at least partially sleeved on the positioning shaft 2 for positioning the wire pressing plate 3 on the positioning shaft 2.

In some embodiments, at least one of the inner surface of the positioning groove 9 and the outer circumferential surface of the positioning shaft 2 is arc-shaped, so that the inner surface of the positioning groove 9 and the outer circumferential surface of the positioning shaft 2 are not clamped during the rotation of the tension bar 3.

Through being equipped with constant head tank 9 in the middle part of line ball board 3, owing to there is the limiting displacement of constant head tank 9, so line ball board 3 is less at the range that the relative location axle 2 of pivoted in-process takes place to slide the skew for line ball board 3 can rotate to preset position and support wire 10 on wiring board 1 along preset direction under the effect of supporting of top pushing element 4, improves the reliability that wire 10 and wiring board 1 electricity are connected. The preset direction is a direction in which the second end 32 of the wire pressing plate 3 rotates to be close to the lead 10, and the preset position is a position in which the wire pressing plate 3 is located when the second end 32 of the wire pressing plate 3 presses against the lead 10.

As shown in fig. 1, 2, 3 and 5, in some embodiments, the terminal further includes a side plate 7, the side plate 7 is disposed at one end or both ends of the positioning shaft 2 for fixing the positioning shaft 2, and the fixing member 5 is connected to the side plate 7.

Based on the foregoing description, the positioning shaft 2 is a part for supporting the wire tension plate 3, so the positioning shaft 2 needs to have a fixed supporting position, for example, the positioning shaft 2 can be fixed in a device using the terminal, for example, a case of the circuit breaker, but this may result in requiring field assembly of each part of the terminal at the time of manufacturing the circuit breaker, resulting in a complicated and time-consuming manufacturing process of the circuit breaker.

This embodiment of this application is through all connecting location axle 2 and mounting 5 on curb plate 7, make curb plate 7, setting element and fixed plate constitute a whole, install ejecting 4 on the fixed plate, and after installing line ball board 3 and wiring board 1, binding post becomes a holistic part, relative position between each structure is fixed, can install binding post in the device that uses it with the state of assembling, avoid assembling each spare part of binding post in the device, binding post's use is more convenient.

Wherein, curb plate 7 can set up in one side of location axle 2, and the one end of location axle 2 fix on this curb plate 7 can, and is the same, and mounting 5 also can only fix on curb plate 7 one end.
