The utility model discloses an aspect provides a binding post, include: a housing 100, and a wire connecting portion 200, a control member 300, a locking member 500 and an elastic member 400 provided on the housing 100; a wiring hole for accessing the lead 600 is further provided on the housing 100; a first end of the elastic member 400 is disposed on the housing 100, and a second end corresponds to the wire connecting portion 200; the control member 300 is provided with an abutting portion 310 and a locking portion 320, respectively; the driving control member 300 slides relative to the housing 100, the abutting portion 310 drives the second end 410 of the elastic member to move away from the wiring portion 200, and the locking portion 320 approaches the locking member 500 for locking; the wire 600 inserted into the wire hole drives the locking member 500 to move to disengage from the locking portion 320, the elastic member 400 acts on the abutting portion 310 to drive the control member 300 to slide, and the second end 410 of the elastic member abuts against the wire 600 to conduct the wire 600 with the wire connecting portion 200.

Illustratively, as shown in fig. 1, the connection terminal includes a housing 100, and a connection hole is provided on the housing 100, so that an external wire 600 can be inserted into the housing 100 through the connection hole until the wire 600 corresponds to the connection portion 200 provided on the housing 100. The elastic member 400 is further disposed on the housing 100, and a first end of the elastic member 400 is disposed on the housing 100, and a second end of the elastic member 400 corresponds to the wire connecting portion 200, so that the wire 600 corresponding to the wire connecting portion 200 can be pressed against the wire connecting portion 200 through the second end 410 of the elastic member, so that the two portions can be kept in a good conduction state.

The housing 100 is further provided with a control member 300, and the control member 300 is formed with a contact portion 310 and a locking portion 320, respectively. The abutting portion 310 always abuts against the elastic member 400. The locking portion 320 is used to cooperate with a separately provided locking member 500 to lock or unlock the control member 300, such that the second end 410 of the elastic member is in a released state when the control member 300 is in the locked state and in a compressed state when the control member 300 is in the unlocked state, respectively.

When the driving control member 300 slides relative to the housing 100, for example, when the external force drives the control member 300 to slide from top to bottom in fig. 1, the abutting portion 310 on the control member 300 pushes the elastic member 400 to deform so as to gradually store elastic potential energy, and at this time, the second end 410 of the elastic member gradually moves away from the wire connection portion 200, thereby providing an insertion space for the connected wire 600. During the sliding of the check member 300, the locking part 320 on the check member 300 is also gradually close to the locking member 500 provided on the housing 100, i.e., the elastic member 400 is gradually pushed away from the wire connecting portion 200 by the abutting part 310 and stores energy while the locking part 320 is close to the locking member 500. Until the locking part 320 of the control member 300 contacts and cooperates with the locking member 500, the control member 300 is locked, the abutting part 310 stops moving and the elastic member 400 is in the compressed energy storage state.

As shown in fig. 2, when the wire 600 is inserted into the wire hole of the wire terminal, one end of the wire 600 contacts with the locking member 500, so as to push the locking member 500 to move by using its own structural strength, such that the locking portion 320, which is originally engaged with the locking member 500 and in a locking state, is disengaged, at this time, the elastic member 400 starts to release the stored elastic potential energy, and the second end 410 of the elastic member starts to move toward the wire connecting portion 200, and since the abutting portion 310 always abuts against the elastic member, while the elastic member 400 moves, the abutting portion 310 is driven to move in an opposite direction (i.e. the direction opposite to the moving direction of the abutting portion 310 when the abutting portion 310 is close to the locking member 500 to achieve locking), such as in fig. 3, from bottom to top, until the second end 410 of the elastic member contacts with the inserted wire 600 and presses the wire connecting portion 200 by using its own elastic potential energy and stops moving, wire 600 will be under the effect of elastic component's second end 410, remain the contact with wiring portion 200 all the time, can be when the wiring through this kind of mode, thereby make elastic component 400 automatic compress tightly wire 600 by the direct unblock elastic component 400 of inserted wire 600 in the motion process, directly break away from the reliance to appurtenance when wiring, and simultaneously, simplify the wiring operation, improve wiring efficiency, because the effect that compresses tightly of elastic component 400, can also improve the stability that switches on between them, and then be convenient for improve binding post's stability.

Optionally, a side wall of the locking portion 320 away from the locking member 500 is a blocking wall 321; a side wall of the locking member 500 away from the locking portion 320 is a locking wall 511; when the locking portion 320 moves toward the locking member 500, the blocking wall 321 engages with the engaging wall 511 to lock the locking portion 320 with the locking member 500.

For example, as shown in fig. 3 and 4, in order to improve the stability of the locking part 320 and the locking member 500 in the locked state, a side wall of the locking part 320 away from the locking member 500 may be provided as a blocking wall 321, and similarly, a side wall of the locking member 500 away from the locking part 320 may be provided as a catching wall 511. When the locking part 320 moves toward the locking member 500, the blocking wall 321 gradually approaches the catching wall 511, and when they correspond to each other, they are attached to each other, thereby forming a stable locking. When the locking portion 320 and the locking member 500 are locked in a matching manner, the control member 300 and the locking member 500 are locked in a matching manner, and at this time, due to the limit relationship between the locking portion 320 and the locking member 500, the abutting portion 310 on the control member 300 can limit the elastic member 400, so that the elastic member is in a corresponding energy storage state. It should be noted that the locking portion 320 may be a side wall of a protrusion or a side wall of a groove, and the present application does not limit the locking portion as long as the locking portion can cooperate with the locking piece 500 to complete the limiting. Correspondingly, the locking member 500 is the same.

Alternatively, the locking member 500 includes a locking portion 510 and an energy storage portion 520 connected to each other; the locking part 510 is rotatably disposed on the housing 100, the locking part 510 is located in the sliding direction of the locking part 320 and the locking wall 511 is located on the locking part 510; when the locking part 320 slides to be close to the locking part 510, the locking part 500 is driven to rotate along the first direction, so that the energy storage part 520 stores energy, and when the blocking wall 321 corresponds to the clamping wall 511, the energy storage part 520 releases energy, so as to drive the locking part 500 to rotate along the second direction, so that the clamping wall 511 is clamped with the blocking wall 321; the first direction is opposite to the second direction.

For example, as shown in fig. 3 and 6, the locking member 500 is rotatably disposed on the housing 100, and correspondingly, the locking member 500 may include a locking portion 510 and an energy storage portion 520, where the locking portion 510 and the energy storage portion 520 are connected to each other, and may be integrally formed or separately formed and then connected to each other, which is not limited in this application. The locking portion 510 is rotatably disposed on the housing 100, and when it rotates, the energy storage portion 520 can be driven to move.

When the locking portion 320 slides close to the locking portion 510, since the locking portion 320 and the locking portion 510 are both provided with protrusions that are engaged with each other, when the locking portion 320 and the locking portion 510 are gradually deeply contacted, the locking member 500 is driven to rotate along a first direction, for example, in fig. 1, the locking portion 510 rotates clockwise by a certain angle. At this time, the energy storage part 520 connected to the locking part 510 is compressed to store elastic potential energy, and when the locking part 320 or the locking part 510 relatively passes over the protrusion, i.e. the blocking wall 321 on the locking part 320 and the blocking wall 511 on the locking part 510 correspond, the energy storage part 520 starts to release energy, so as to drive the locking part 510 to rotate in a second direction opposite to the first direction, for example, the locking part 510 rotates in a counterclockwise direction in fig. 1. At this time, the clamping wall 511 and the blocking wall 321 are attached to each other, and a limit is formed in the sliding direction of the control member 300, so that the control member 300 is in a locked state with respect to the locking member 500.

In addition, the energy storage part 520 may also be disposed at a position corresponding to the wire connecting part 200, that is, as shown in fig. 2, the locking part 510 and the energy storage part 520 are disposed at an angle to each other, wherein the extending direction of the energy storage part 520 intersects with the wire length direction of the wire 600. When the control member 300 is in a locked state with respect to the locking member 500 (at this time, the elastic member 400 is in a compressed state, i.e., an energy storage state), the wire 600 is inserted into the wiring terminal from the wiring hole, and moves to the energy storage portion 520 of the locking member 500, one end of the wire 600 contacts the energy storage portion 520, and under the structural strength of the wire 600 itself, the energy storage portion 520 is pushed to store energy, at this time, the energy storage portion 520 drives the locking portion 510 to rotate in a first direction, e.g., clockwise in fig. 2, at this time, the locking wall 511 is disengaged from the blocking wall 321, i.e., the locking portion 510 on the locking member 500 is disengaged from the locking portion 320 on the control member 300, the control member 300 is unlocked and returns to a free state, at this time, the elastic member 400 releases energy, the second end 410 of the elastic member moves in a direction close to the wire 600 (i.e., close to the, thereby realizing the stable conduction of the two. This kind of mode that compresses tightly wire 600 is comparatively ingenious, utilizes the structural strength of wire 600 self to carry out the unblock to the elastic component 400 in the binding post to the effect that the realization compressed tightly promptly has improved binding post's use and has experienced.

When the wire 600 needs to be removed, the control member 300 is driven to slide towards the direction of the locking portion 510 in the locking member 500, at this time, the abutting portion 310 on the control member 300 drives the second end 410 of the elastic member to be away from the wire 600, that is, the pressing effect of the elastic member on the wire 600 is released, at this time, the wire 600 can be directly pulled out, the energy storage portion 520 connected with the locking portion 510 starts to release energy, the locking portion 510 is pushed to reset, and when the locking portion 320 on the control member 300 moves to the locking position, the locking portion 320 and the locking portion 510 complete locking again through the blocking wall 321 and the clamping wall 511. The wire 600 may not be directly pulled out, and the wire 600 may be pushed away by the stored energy of the energy storage part 520 in the locking member 500. After the locking part 320 and the locking member 500 are locked again, the lead is pulled out. Through the setting of energy storage portion 520, not only can improve wire 600 and insert the automation that targets in place promptly to realize being compressed tightly and use experience, can also make the latched position of control piece 300 and hasp portion 510 remain invariable throughout, effectively improve the accuracy and the stability of both locks.

Alternatively, the locking portion 320 and the latching portion 510 are both rigid members.

For example, the locking portion 320 may be a rigid member, and the locking portion 510 may also be a rigid member, so as to effectively reduce the hooking amount during locking of the two. Meanwhile, the stability of the locking device and the locking device during locking is further improved. In addition, the locking part 320 and the locking part 510 may be made of plastic or metal with high hardness. When the two are plastic parts with higher hardness, the difficulty of the manufacturing processes of the two parts can be reduced, and the manufacturing cost of the whole wiring terminal can be reduced.

Alternatively, one side wall of the locking portion 320 adjacent to the catch piece 500 is a first guide wall 322; one side wall of the locking member 500 near the locking portion 320 is a second guide wall 512; the first and

second guide walls

322 and 512 cooperate to guide the engagement wall 511 into engagement with the blocking wall 321.

For example, in order to improve the smoothness of the locking portion 320 and the locking member 500 and reduce the contact strength therebetween, as shown in fig. 3 and 4, a side wall of the locking portion 320 close to the locking member 500 may be provided as the first guide wall 322, and similarly, a side wall of the locking member 500 close to the locking portion 320 may be provided as the second guide wall 512. The first guiding wall 322 may be an arc-shaped surface, an inclined surface as shown in fig. 4, and the like, which is not particularly limited in the present application. The second guide wall 512 works the same. For example, as shown in fig. 3, when the first guiding wall 322 and the second guiding wall 512 are both inclined surfaces, they can be kept in a corresponding fit relationship when they are not in contact, so that when the control member 300 slides to drive the locking portion 320 to approach the locking portion 510, the first guiding wall 322 on the locking portion 320 gradually approaches the second guiding wall 512 on the locking member 500, and when the locking portion 320 contacts the locking member 500, the two guide walls contact through the two inclined surfaces, thereby effectively reducing the stress when the two guide walls contact and improving the service life of the control member 300 and the locking member 500.

Optionally, a through hole 323 or a through groove is provided on the control member 300, and the second end 410 of the elastic member penetrates out of the control member 300 through the through hole 323 or the through groove to correspond to the wire connecting portion 200; the sidewall of the through hole 323 or the through groove forms an abutting portion 310 to abut against the elastic member 400.

For example, as shown in fig. 4, a through hole 323 or a through groove may be further provided on the control member 300, and both of the through holes 323 or the through groove extend in the same direction, and the second end 410 of the elastic member penetrates through the through hole 323 or the through groove to correspond to the wire connection portion 200, that is, the first end and the second end of the elastic member 400 are located at two sides of the control member 300, and the wire connection portion 200 and the second end 410 of the elastic member are located at the same side of the control member 300. In order to realize the abutting between the abutting portion 310 and the elastic member 400, the portion of the through hole 323 or the through groove abutting against the elastic member 400 may be the abutting portion 310. This kind of mode of setting up can effectual improvement binding post internal layout's compactification, is convenient for realize binding post's miniaturization.

Optionally, the abutting portion 310 is an arc-shaped abutting portion 310.

For example, as shown in fig. 4, in order to further reduce the stress concentration when the abutting portion 310 abuts against the elastic member 400, the abutting portion 310 may be configured as an arc-shaped abutting portion 310, so that the arc-shaped surface of the abutting portion 310 abuts against the elastic member 400.

Optionally, the elastic element 400 includes a supporting portion 430 and a pressing portion 420 that are connected to each other, a fixing hole or a fixing groove is further disposed on the casing 100, the pressing portion 420 of the elastic element 400 passes through the fixing hole or the fixing groove to abut against the abutting portion 310, and the supporting portion 430 abuts against the casing 100.

As shown in fig. 5, the elastic member 400 includes a supporting portion 430 and a pressing portion 420, and a fixing hole or a fixing groove may be further disposed on the casing 100, so that a portion of the elastic member 400 is located in the fixing hole or the fixing groove, for example, the pressing portion 420 of the elastic member 400 passes through the fixing hole or the fixing groove and abuts against the abutting portion 310 on the control member 300, and the supporting portion 430 abuts against the casing 100. By sliding the control member 300, the abutting portion 310 is driven to push the pressing portion 420 to approach the supporting portion 430, thereby completing energy storage. When the control member 300 is further provided with the through hole 323 or the through groove, the pressing portion 420 further passes through the through hole 323 or the through groove of the control member 300, and thus corresponds to the wire connecting portion 200. The elastic member 400 may be a spring plate as shown in fig. 5, a torsion spring, or the like.

Optionally, a sliding hole is formed in the housing 100, and the control member 300 is located in the sliding hole and can slide along the extending direction of the sliding hole.

For example, as shown in fig. 1, in order to control the sliding direction of the control member 300 and improve the stability of the control member during sliding, a sliding hole may be further provided on the housing 100, and the control member 300 and the sliding hole may be corresponding, for example, when the cross section of the control member 300 is circular, the radial section of the corresponding sliding hole is also circular, when the cross section of the control member 300 is square, the radial section of the corresponding sliding hole is also square, and so on. Thereby further improving the assembling accuracy of the control member 300 and the housing 100 and achieving more stable sliding.

For example, when the terminal is installed in a circuit breaker, the second end 410 of the elastic member may press the connected wire 600, so as to fix the wire 600, and the wire 600 and the terminal portion 200 may maintain a stable conductive state. The elastic member 400 can be directly unlocked by the access wire 600, so that the elastic member automatically compresses the wire 600, and the operation of connecting the wiring terminal into the wire 600 in the circuit breaker can be effectively simplified.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
