Technical Field

The application relates to the field of electrical technology, in particular to a wiring terminal, an electric energy transmission component and an electric energy transmission system.

Background

A connection terminal is a device for connecting a cable, by which connection and detachment of the cable can be facilitated.

In the related art, a connection terminal includes: the shell, the elastic sheet and the conductive piece are arranged in the shell, the shell is provided with a wiring port through which a cable passes and enters the shell, and the elastic sheet can rotate in the direction close to the conductive piece, so that the cable is pressed on the conductive piece, and the cable is in contact with the conductive piece.

However, since the amount of deformation of the spring plate is limited, the range of the diameter of the cable that can be crimped is small, resulting in poor flexibility in use of the terminal.

SUMMERY OF THE UTILITY MODEL

The application provides a binding post, electric energy transmission part and electric energy transmission system, can solve the relatively poor problem of binding post's use flexibility among the correlation technique. The technical scheme is as follows:

in one aspect, there is provided a connection terminal, which may include: a housing, and an electrically conductive member and one or more crimp assemblies disposed within the housing; each of the crimping assemblies may include: the driving part, the rotating shaft and the crimping part.

The rotating shaft can be located between the driving piece and the conductive piece, the crimping piece can be rotatably connected with the rotating shaft, the end portion, close to the conductive piece, of the crimping piece can comprise a plurality of crimping ends, the driving piece can move relative to the shell, the crimping piece is driven to rotate around the rotating shaft, and the crimping ends move in the direction close to the conductive piece.

The casing may be provided with a connection port for inserting a cable, a moving direction of the driving member may be parallel to an axis of the connection port, or an included angle between the moving direction of the driving member and the axis of the connection port may be a fixed angle, an included angle may exist between the axis of the rotation shaft and the axis of the connection port, when the crimping member rotates around the rotation shaft by a first angle, distances between at least two crimping ends of the plurality of crimping ends and the conductive member are different, when the crimping member rotates around the rotation shaft by a second angle, distances between at least two crimping ends of the plurality of crimping ends and the conductive member are the same, and a distance between any one crimping end and the conductive member at the second angle may be greater than a distance between each crimping end and the conductive member at the first angle.

Since the intervals between at least two of the plurality of crimping ends and the conductive member are different when the crimping member is rotated by a first angle about the rotating shaft, the intervals between at least two of the plurality of crimping ends and the conductive member are the same and larger when the crimping member is rotated by a second angle about the rotating shaft. Therefore, when the crimping piece rotates around the rotating shaft by a first angle, the crimping end closer to the conductive piece can crimp the cable with a smaller diameter; when the crimping piece rotates around the rotating shaft by a second angle, at least two crimping ends can simultaneously crimp cables with larger diameters, and the crimping reliability is better. The wiring terminal can be used for crimping cables with smaller diameters, can also ensure the reliability of crimping when cables with larger diameters are crimped, and is good in use flexibility.

And the moving direction of the driving piece is parallel to the axis of the wiring port, or the included angle between the moving direction of the driving piece and the axis of the wiring port is a fixed angle, so that the driving piece can move only in the moving direction of the driving piece, and the problem that the wiring terminal occupies a large space is avoided.

Optionally, the crimping assembly and the wiring port are located on the same side of the housing, and the plurality of crimping ends are sequentially arranged in a direction away from the wiring port. When the crimping piece rotates around the rotating shaft by a first angle, the distance between the plurality of crimping ends and the conductive piece is gradually reduced along the direction far away from the wire connection port.

Alternatively, the crimping assembly and the wiring port may be located at different sides of the housing, and the plurality of crimping ends may be arranged in sequence in a direction away from the wiring port. When the crimping piece rotates around the rotating shaft by a first angle, the distance between the plurality of crimping ends and the conductive piece can be gradually increased along the direction far away from the wiring port.

Optionally, the driving member may include: a screw and a nut. The nut is fixed in the shell and is positioned on one side, close to the wiring port, of the crimping piece, and an included angle exists between the axis of the nut and the axis of the rotating shaft. The screw is in threaded connection with the nut, and can be in contact with one side of the crimping piece close to the nut after penetrating through the nut from one side of the nut far away from the crimping piece.

When the driving screw continues to move along the axis of the nut to the direction close to the crimping piece, the crimping piece can be pushed to rotate around the rotating shaft, so that the crimping end of the crimping piece moves to the direction close to the conductive piece, and the cable is crimped.

And because the nut is fixedly arranged in the shell, when the screw and the nut move relatively, the nut can be ensured not to move relative to the shell, and the driving piece can effectively drive the pressing piece to rotate.

Optionally, a through hole may be further provided on a side of the housing adjacent to the nut, and an axis of the through hole is collinear with an axis of the nut.

Because the moving direction of the screw is the moving direction of the driving piece, and the moving direction of the screw is the axis of the nut, the moving direction of the driving piece can be parallel to the axis of the wiring port, or the included angle between the moving direction of the driving piece and the axis of the wiring port is a fixed angle, so that the occupied space of the wiring terminal is reduced, and the wiring terminal is easy to install and maintain.

Optionally, the connection terminal further includes: and a limiting member. This locating part sets up in this casing, and is located this pivot and keeps away from one side of this wiring mouth, and this locating part is used for restricting the turned angle of this crimping piece, avoids because driving piece drive crimping piece revolutes the rotatory angle of rotation too big, and the effort to the cable crimping of crimping is great, leads to the cable to damage, guarantees the reliability of cable transmission electric energy.

Optionally, the position-limiting member may be a rod-shaped structure, and an axis of the position-limiting member may be parallel to an axis of the rotating shaft. Alternatively, the limiting member may be a plate-shaped structure, and a plate surface of the limiting member may be parallel to the axis of the rotating shaft.

Optionally, the conductive member is a sheet structure, and a plane of the conductive member is parallel to the axis of the wire connection port and parallel to the axis of the rotating shaft.

Optionally, one end of the conductive component close to the wiring port is wavy, and the orthographic projection of the crimping component on the plane where the conductive component is located overlaps with the wavy region of the conductive component, so that the roughness of the conductive component can be increased, the cable and the conductive component are prevented from shaking, and the contact tightness of the cable and the conductive component is ensured.

Optionally, the crimp member comprises: a plurality of crimping pieces. The relative positions of the ends of the plurality of the crimping pieces far away from the conductive piece are fixed, and one end of each crimping piece near the conductive piece forms one crimping end.

Optionally, a plurality of the crimping pieces include: a first crimping piece and a second crimping piece. The first pressing piece and the second pressing piece are located on two sides of the rotating shaft, or the first pressing piece and the second pressing piece are located on one side, close to the wiring opening, of the rotating shaft.

Optionally, one end of each of the plurality of crimping pieces, which is far away from the conductive piece, is of an integrated structure; or one end of the plurality of crimping pieces far away from the conductive piece is fixedly connected.

Optionally, each of the crimping ends is bent in a direction close to the wire connection port. Wherein, the bending angle of each crimping end is a right angle or an obtuse angle. Through buckling the crimping end to the direction that is close to the wiring mouth, can be so that the cable inserts this binding post back, the contained angle of every crimping end and the axis of cable is the acute angle, and this acute angle can form the barb effect, avoids this cable to be pulled out, improves the reliability of crimping piece crimping cable.

Optionally, the terminal may include two opposite crimping assemblies, and two one-to-one corresponding terminal ports of the two crimping assemblies are oppositely disposed on the housing. Each crimping assembly is positioned on one side of the shell body close to the corresponding wire connection port. That is, each crimping assembly may be used to crimp a cable inserted from a corresponding patch port.

The end of the crimping member near the conductive member may include a plurality of crimping ends. Since the intervals between at least two of the plurality of crimping ends and the conductive member are different when the crimping member is rotated by a first angle about the rotating shaft, the intervals between at least two of the plurality of crimping ends and the conductive member are the same and larger when the crimping member is rotated by a second angle about the rotating shaft. Therefore, when the crimping piece rotates around the rotating shaft by a first angle, the crimping end closer to the conductive piece can crimp the cable with a smaller diameter; when the crimping piece rotates around the rotating shaft by a second angle, at least two crimping ends can simultaneously crimp cables with larger diameters, and the crimping reliability is better.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a connection terminal provided in an embodiment of the present invention, and fig. 2 is a schematic structural diagram of another connection terminal provided in an embodiment of the present invention. As can be seen with reference to fig. 1 and 2, the connection terminal 00 may include: a housing 001, and an electrically conductive member 002 and one or more crimp assemblies 003 disposed within the housing 001. For example, figure 1 shows one crimp assembly 003 and figure 2 shows two crimp assemblies 003. Wherein each crimp assembly 003 can include: a driving member 0031, a rotating shaft 0032, and a pressure contact member 0033.

The rotation shaft 0032 may be located between the driving member 0031 and the conductive member 002, the pressing member 0033 may be rotatably connected to the rotation shaft 0032, and an end of the pressing member 0033 adjacent to the conductive member 002 may include a plurality of pressing ends 0033 a. For example, in the terminal 00 shown in fig. 1 and 2, each end of the crimp member 003 near the conductive member 002 includes two crimp ends 0033 a.

In this case, the driving member 0031 can move relative to the housing 001, and the driving member 0031 can drive the pressing member 0033 to rotate around the rotating shaft 0032, so that the plurality of pressing ends 0033a can move in a direction close to the conductive member 002, that is, the distance between each pressing end 0033a and the conductive member 002 can be gradually reduced.

As shown in fig. 1 and 2, a wire connection port 001a for inserting a cable is provided on the housing 001, and the moving direction X of the driving element 0031 may be parallel to the axis of the wire connection port 001a, or an included angle between the moving direction X of the driving element 0031 and the axis of the wire connection port 001a is a fixed angle. The fixed angle may range from 0 degree to 180 degrees, for example, may be 90 degrees. The axis of the rotating shaft 0032 may be at an angle with the axis of the wiring port 001 a. For example, the axis of the rotating shaft 0032 may be perpendicular to the axis of the wire connection port 001 a. The axis of the rotating shaft 0032 may be out of plane with the axis of the wiring port 001 a. When the pressure contact member 0033 is rotated by a first angle about the rotating shaft 0032, the intervals between at least two pressure contact ends 0033a of the plurality of pressure contact ends 0033a and the conductive member 002 are different, and when the pressure contact member 0033 is rotated by a second angle about the rotating shaft 0032, the intervals between at least two pressure contact ends 0033a of the plurality of pressure contact ends 0033a and the conductive member 002 are the same. Here, each of the first angle and the second angle may be an angle at which the pressure contact member 0033 starts to rotate around the rotating shaft 0032 from a free state, and a distance between any one of the pressure contact ends 0033a and the conductive member 002 at the second angle of the pressure contact member 0033 may be larger than a distance between each of the pressure contact ends 0033a and the conductive member 002 at the first angle. The free state may be a state where the pressure contact 0033 is not subjected to an external force, and in the embodiment of the present invention, the external force may be from the driving member 0031 or may be from the cable 10.

On the one hand, referring to fig. 3, when the crimp member 0033 is in a free state, a plurality of crimp ends 0033a may be located at positions distant from the conductive member 002, with a larger distance between each crimp end 0033a and the conductive member 002. At this time, the driver 0031 can drive the pressing member 0033 to rotate. On the other hand, referring to fig. 4, when the crimp member 0033 is in a free state, a plurality of crimp ends 0033a may be located at positions close to the conductive member 002, with a smaller interval between each crimp end 0033a and the conductive member 002. At this time, the cable 10 can drive the crimp 0033 to rotate.

Since the interval between at least two crimp ends 0033a of the plurality of crimp ends 0033a of the crimp member 0033 and the conductive member 002 is the same and larger when the crimp member 0033 is rotated by the second angle along the rotation shaft 0032, referring to fig. 5, the at least two crimp ends 0033a can crimp a thicker (i.e., larger diameter) cable 10. Further, since the plurality of crimp ends 0033a can provide a good crimping effect to the cable 10, the reliability of crimping the cable 10 is good.

Referring to fig. 6, when the angle of rotation of the crimp member 0033 about the rotation shaft 0032 is a first angle, the crimp end 0033a spaced more apart from the conductive member 002 of the at least two crimp ends 0033a may not contact the cable 10, and only the crimp end 0033a spaced less apart from the conductive member 002 contacts the cable 10, i.e., the crimp end 0033a spaced less apart from the conductive member 002 of the at least two crimp ends 0033a may be used to crimp the thinner (i.e., smaller in diameter) cable 10.

That is, the embodiment of the utility model provides a binding post 00 not only can the less cable 10 of crimping diameter, also can guarantee the reliability of crimping when the great cable 10 of crimping diameter, and this binding post 00's use flexibility is better.

Moreover, because the moving direction X of the driving element 0031 is parallel to the axis of the wiring port 001a, or the included angle between the moving direction X of the driving element 0031 and the axis of the wiring port 001a can be a fixed angle, that is, the moving direction X of the driving element 0031 can be the same as the extending direction of the cable 10, or the moving direction X of the driving element 0031 can be a fixed angle with the included angle between the cables 10, a space can be reserved only in the moving direction X of the driving element 0031 for the driving element 0031 to move, and the problem that the occupied space of the wiring terminal 00 is large is avoided.

To sum up, the embodiment of the utility model provides a binding post, this binding post can include: a housing, and an electrically conductive member and one or more crimp assemblies disposed within the housing, each crimp assembly may include: driving piece, pivot and crimping piece. The end of the crimping member near the conductive member may include a plurality of crimping ends. Since the intervals between at least two of the plurality of crimping ends and the conductive member are different when the crimping member is rotated by a first angle about the rotating shaft, the intervals between at least two of the plurality of crimping ends and the conductive member are the same and larger when the crimping member is rotated by a second angle about the rotating shaft. Therefore, when the crimping piece rotates around the rotating shaft by a first angle, the crimping end closer to the conductive piece can be directly crimped with the cable with a smaller diameter; when the crimping piece rotates around the rotating shaft by a second angle, at least two crimping ends can simultaneously crimp cables with larger diameters, and the crimping reliability is better. The embodiment of the utility model provides a binding post not only can the less cable of crimping diameter, also can guarantee the reliability of crimping when the great cable of crimping diameter, and this binding post's use flexibility is better.

As an alternative implementation, as shown in fig. 3, assuming that the plurality of crimp ends 0033a are located at a position away from the conductive member 002 when the crimp member 0033 is in a free state, the crimp member 0033 may be under its own elastic force before the cable 10 is inserted from the wiring port 001a so that the plurality of crimp ends 0033a can be located at a position away from the conductive member 002 with the wiring terminal 00 in an unlocked state. Thereafter, the cable 10 can be inserted into the housing 001 through the wiring port 001a, and then the driving member 0031 drives the crimping member 0033 to rotate about the rotating shaft 0032, so that the plurality of crimping ends 0033a move in a direction close to the conductive member 002, so that the plurality of crimping ends 0033a can crimp the cable 10, thereby achieving reliable connection of the cable 10 and the conductive member 002.

In this implementation, when the cable 10 is thick, the angle at which the driver 0031 drives the crimp 0033 to rotate about the axis 0032 is small; when the cable 10 is thin, the angle at which the driver 0031 drives the press-fitting member 0033 to rotate about the rotating shaft 0032 is large. That is, in this implementation, the first angle may be greater than the second angle.

As another alternative implementation, as shown in fig. 4, assuming that the crimping member 0033 is in a free state, the crimping member 0033 is under the action of its own weight so that a plurality of crimping ends 0033a can be located at positions close to the conductive member 002. Before the cable 10 is inserted from the wire connection port 001a, the driving member 0031 may be moved in a direction away from the crimping member 0033 to place the wire connection terminal 00 in an unlocked state. Thereafter, the cable 10 can be inserted into the housing 001 from the wire connection port 001a, and during the insertion of the cable 10 into the housing 001, the cable 10 can be brought into contact with the crimp terminal 0033a and can push the crimp member 0033 to rotate about the rotation shaft 0032 in a direction away from the conductive member 002. At this time, the crimp end 0033a of the crimp 0033 is only in contact with the cable 10, and does not perform a crimping action on the cable 10. After the insertion of the cable 10 is completed, the driving member 0031 can be moved in the direction close to the crimping member 0033, the driving member 0031 can be brought into contact with the crimping member 0033, and the crimping member 0033 is driven to rotate about the rotating shaft 0032, so that the crimping end 0033a can be moved in the direction close to the conductive member 002, and then an acting force is applied to the cable 10, so that the plurality of crimping ends 0033a can crimp the cable 10, thereby realizing the reliable connection of the cable 10 and the conductive member 002.

In this implementation, when the cable 10 is thick, the angle at which the cable 10 drives the rotation of the crimp 0033 about the rotation shaft 0032 is large; when the cable 10 is thin, the angle by which the cable 10 drives the rotation of the crimp 0033 about the rotation shaft 0032 is small. That is, in this implementation, the first angle may be less than the second angle.

Alternatively, referring to fig. 1 to 6, the crimping assembly 003 and the corresponding one of the wiring ports 001a may be located on the same side of the housing 001, and the plurality of crimping ends 0033a may be sequentially arranged in a direction away from the corresponding wiring port 001 a. When the crimp member 0033 is rotated by a first angle about the rotation shaft 0032, the intervals between the plurality of crimp ends 0033a and the conductive member 002 may be gradually decreased in a direction away from the wire connection port 001 a. That is, when the crimp member 0033 is rotated by a first angle about the rotation shaft 0032, of at least two crimp ends 0033a of the plurality of crimp ends 0033a, a distance between one crimp end 0033a close to the wire connection port 001a and the conductive member 002 may be larger, and a distance between one crimp end 0033a far from the wire connection port 001a and the conductive member 002 may be smaller.

Alternatively, referring to fig. 7, the crimp assembly 003 and the corresponding one of the wire ports 001a may be located on different sides of the housing 001. The plurality of crimp terminals 0033a may be sequentially arranged in a direction away from the wiring port 001 a. When the crimp member 0033 is rotated by a first angle about the rotation shaft 0032, the intervals between the plurality of crimp ends 0033a and the conductive member 002 may be gradually increased in a direction away from the wire connection port 001 a. That is, when the crimp member 0033 is rotated by a first angle about the rotation shaft 0032, the interval between one crimp end 0033a close to the wire connection port 001a and the conductive member 002 among at least two crimp ends 0033a of the plurality of crimp ends 0033a and the conductive member 002 may be small, and the interval between one crimp end 0033a far from the wire connection port 001a and thus the conductive member 002 may be large.

As can be seen with reference to fig. 3 to 7, the driving member 0031 may include: screws 00311 and nuts 00312. The nut 00312 may be fixed in the housing 001, and the nut 00312 may be located on the side of the crimp member 0033 near the wiring port 001a, and the axis of the nut 00312 may be angled with respect to the axis of the rotating shaft 0032, for example, the axis of the nut 00312 may be perpendicular to the axis of the rotating shaft 0032.

Here, the screw 00311 may be screwed to the nut 00312, and the screw 00311 may be brought into contact with a side of the nut 00312 near the nut 00312 after passing through the nut 00312 from a side of the nut 00312 far from the crimp 0033. When the driving screw 00311 continues to move in the direction of approaching the crimp member 0033 along the axis of the nut 00312, the crimp member 0033 can be pushed to rotate about the rotating shaft 0032, so that the crimp end 0033a of the crimp member 0033 moves in the direction of approaching the conductive member 002, and the cable 10 is crimped.

Because nut 00312 is fixed and set up in casing 001, consequently when screw 00311 and nut 00312 relative motion, can guarantee that nut 00312 can not remove for casing 001, guarantee that this driving piece 0031 can effectively drive the rotation of pressing-in piece 0033.

In the embodiment of the utility model, because the moving direction of screw 00311 is the moving direction X of this driving piece 0031 promptly, and the moving direction of this screw 00311 is the axis of nut 00312 promptly, consequently the axis of this nut 00312 is on a parallel with the axis of wiring mouth 001a, or, contained angle between the axis of nut 00312 and the axis of wiring mouth 001a is fixed angle, the moving direction X that can realize driving piece 0031 is on a parallel with the axis of wiring mouth 001a, the moving direction X of driving piece 0031 is on a parallel with the extending direction of cable 10 promptly, or, contained angle between moving direction X that can realize driving piece 0031 and the wiring mouth 001a is fixed angle, can reduce the occupation space of this binding post 00, easily installation and maintenance.

Alternatively, referring to fig. 3 to 7, a side of the housing 001 adjacent to the nut 00312 may be provided with a through hole 001b, and an axis of the through hole 001b may be collinear with an axis of the nut 00312. The axis of the through hole 001b may be parallel to the axis of the wire connection port 001a, or the included angle between the axis of the through hole 001b and the axis of the wire connection port 001a may be a fixed angle. By providing the through hole 001b on the housing 001, it is convenient for the operator to adjust the position of the screw 00311 through the through hole 001b, i.e., to adjust the distance of the screw protruding relative to the nut, so that the adjusting screw 00311 drives the angle of rotation of the crimping member 0033, thereby adjusting the tightness of the crimping member 0033 for crimping the cable 10.

As an alternative implementation, assuming that the plurality of crimp ends 0033a are located at a position away from the conductive member 002 when the crimp member 0033 is in a free state, referring to fig. 3, before inserting the cable 10 from the wire connection port 001a, an operator may first move the screw 00311 along the axis of the nut 00312 in a direction away from the crimp member 0033 using a screwdriver so that the crimp member 0033 is in a free state (which may also be referred to as an unlocked state) when each crimp end 0033a of the crimp member 0033 has a larger distance from the conductive member 002. Thereafter, the operator can insert the cable 10 into the housing 001 from the wire connection port 001a, and then move the screw 00311 in a direction approaching the crimp 0033 along the axis of the nut 00312, and come into contact with the crimp 0033, and gradually lock the screw 00311 with a screwdriver. In the locking process of the screw 00311, the screw 00311 can gradually press the pressing member 0033, so that the pressing member 0033 can rotate around the rotating shaft 0032, each pressing end 0033a of the pressing member 0033 can move in the direction close to the conductive member 002, in the process that the screw 00311 gradually presses the pressing member 0033, the pressing end 0033a can be contacted with the cable 10, the pressing end 0033a can deform, and the locking screw 00311 can be stopped after the reliable connection of the cable 10 and the conductive member 002 is ensured.

Alternatively, in the embodiment of the present invention, in order to move the screw 00311 in the direction away from the crimping member 0033 along the axis of the nut 00312, the crimping member 0033 may be under its own elastic force so that the plurality of crimping ends 0033a can be located at the position away from the conductive member 002 such as shown in fig. 5, that is, so that the connection terminal 00 can be in the unlocked state, the crimping member 0033 may further include a spring. One end of the spring may be connected to an end of the pressure-contact member 0033 distant from the conductive member 002, and the other end may be connected to a nut 00312, and the spring may be stretched when the screw presses the pressure-contact member 0033 step by step in the locking of the screw 00311. When the screw 00311 is moved in a direction away from the crimping member 0033 along the axis of the nut 00312, the spring can be under its own elastic force, so that the terminal 00 can be in an unlocked state.

Alternatively, referring to fig. 8, the crimp member 0033 may include an elastic part 0033b and a crimping part 0033c, and a blocking structure for limiting the rotation of the elastic part 0033b may be provided in the housing 001, and when the screw 00311 gradually presses one end of the crimp member 0033 away from the conductive member 002 during the locking of the screw 00311, the crimping part 0033c may move toward the conductive member 002 to crimp the cable 10, and the elastic part 0033b may be blocked by the blocking structure and may not move toward the conductive member 002, at which time the elastic part 0033b may deform. When the screw 00311 is moved in a direction away from the crimping part 0033 along the axis of the nut 00312, the elastic part 0033b can move the crimping part 0033c in a direction away from the conductive member 002 by its own elastic force, that is, the connection terminal 00 can be in an unlocked state.

As another alternative implementation, provided that the pressure contact 0033 is in a free state, the pressure contact 0033 is under the action of its own weight so that a plurality of pressure contact ends 0033a can be located at positions close to the conductive member 002. Referring to fig. 4, before inserting the cable 10 from the wire connection port 001a, an operator may first move the screw 00311 along the axis of the nut 00312 in a direction away from the crimp 0033 using a screwdriver, so that the wire connection terminal 00 is in an unlocked state in which the crimp ends 0033a of the crimp 0033 are each spaced apart from the conductive member 002 by a small distance. Thereafter, the operator can insert the cable 10 into the housing 001 from the wire connection port 001a, and during the insertion of the cable 10 into the housing 001, the cable 10 can contact the crimp end 0033a and can push the crimp 0033 to rotate about the rotation axis, at which time the crimp end 0033a of the crimp 0033 contacts only the cable 10 and does not crimp the cable 10. Therefore, it is possible to move the screw 00311 in the direction approaching the pressure-contact member 0033 along the axis of the nut 00312 and to come into contact with the pressure-contact member 0033, and to gradually lock the screw 00311 with a driver. In the process of locking the screw 00311, the screw 00311 can gradually press the crimping member 0033, so that the crimping end 0033a can apply an acting force to the cable 10, the plurality of crimping ends 0033a can crimp the cable 10, and the locking screw 00311 can be stopped after the cable 10 is reliably connected with the conductive member 002.
