Description

Technical Field

[0001] The present invention relates to the technical field of electrical machinery, and in particular to a wiring terminal and a wiring block. Background Art

[0002] In order to achieve line connection, it is usually necessary to plug the wire into the terminal and make the conductive body of the wire electrically connected to the terminal. In the related art, in order to facilitate the plugging of the wire into the terminal and avoid the situation where the wire is difficult to insert into the terminal, the connection tightness between the terminal and the wire is usually poor. However, this will result in a smaller effective electrical connection area between the conductive body and the terminal. On the one hand, it will cause poor quality or even interruption of electrical signal transmission. On the other hand, it will also cause the connection between the conductive body and the terminal to have too much resistance, thereby causing a large amount of heat to be generated at the connection, causing dangers such as wire overload, short circuit or fire. In addition, it will also lead to poor reliability of the electrical connection between the conductive body and the terminal. The wire is easy to loosen during use, resulting in a further reduction in the effective electrical connection area between the conductive body and the terminal, and even causing the wire to fall off.

[0029] In addition, since the follower assembly, the clamping assembly and the locking assembly are all located in the accommodating cavity, and the clamping assembly presses the conductive body against the cavity wall of the accommodating cavity in the accommodating cavity, during the use of the terminal block, the follower assembly, the clamping assembly and the locking assembly can be protected by the shell to avoid the influence of the external environment, which may cause the clamping effect of the clamping assembly on the conductive body to fail, or the locking effect of the locking assembly on the first locking piece to fail, so as to improve the connection reliability between the terminal block and the wire.

[0048] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the described embodiments are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0049] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0050] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0051] like Figures 1 to 4 As shown, the present invention provides a terminal block 1 for connecting a power line 2 , wherein the power line 2 includes a conductive body 20 and an insulating layer 21 disposed on the outer periphery of the conductive body 20 , and the outer periphery of the end of the conductive body 20 is not covered with the insulating layer 21 .

[0052] Specifically, the terminal block 1 includes a housing 10, a follower assembly 11, a pressing assembly 12, and a locking assembly 13. The housing 10 has a housing cavity 100, and a first insertion hole 101 connected to the housing cavity 100 is opened on one side of the housing 10. The first insertion hole 101 is extended along the first direction S1. The follower assembly 11 is slidably arranged in the housing cavity 100 along the first direction S1. The follower assembly 11 includes a sleeve 110 and a first locking member 111. The sleeve 110 has a second insertion hole 110a extending along the first direction S1. The second insertion hole 110a can be connected to the first insertion hole 101. The second insertion hole 110a is used for inserting the conductive body 20. The side of the sleeve 110 close to the first insertion hole 101 is used to abut against the insulating skin 21. The first locking member 111 is connected to the outer periphery of the sleeve 110, and the first locking member 111 extends from the sleeve 110 along the first direction S1 away from the first insertion hole 101. The clamping assembly 12 is arranged in the accommodating cavity 100 and is located on the side of the sleeve 110 away from the first jack 101. The clamping assembly 12 includes a first transmission mechanism 120 and a wiring clamping member 121. The first transmission mechanism 120 is connected between the sleeve 110 and the wiring clamping member 121. The first transmission mechanism 120 can convert the sliding output of the sleeve 110 along the first direction S1 into sliding along the second direction S2, so that when the insulating skin 21 abuts against the sleeve 110 and slides along the first direction S1, the wiring clamping member 121 is driven to slide along the second direction S2 to press the conductive body 20 against the cavity wall of the accommodating cavity 100. The locking assembly 13 is arranged in the accommodating cavity 100, and the locking assembly 13 can lock the first locking member 111, wherein the second direction S2 is perpendicular to the first direction S1.

[0053] By setting up the follower component 11, when the wire 2 is inserted into the first jack 101, the conductive body 20 can be inserted into the second jack 110a. At the same time, the insulating skin 21 is pressed against the sleeve 110 along the first direction S1 to push the sleeve 110 to slide toward the clamping component 12 along the first direction S1, and the conductive body 20 is partially located between the wiring clamping member 121 and the cavity wall of the accommodating cavity 100. At this time, the first transmission mechanism 120 converts the sliding output of the sleeve 110 along the first direction S1 into sliding along the second direction S2 to drive the wiring clamping member 121 to slide toward the conductive body 20 along the second direction S2, so that the wiring clamping member 121 presses the conductive body 20 against the cavity wall of the accommodating cavity 100, and at the same time, the wiring clamping member 121 is electrically conductive with the conductive body 20 to achieve a tight connection between the conductive body 20 and the terminal 1.

[0054] Furthermore, by providing a locking assembly 13, the first locking member 111 can be locked while the wiring clamping member 121 is pressed against the conductive body 20, so that the wiring clamping member 121 can be easily maintained in a state of being pressed against the conductive body 20, so that during use, the wiring clamping member 121 can continuously press the conductive body 20, thereby keeping the wire 2 and the terminal 1 in a tightly connected state, and the connection reliability between the terminal 1 and the wire 2 is good.

[0055] In addition, since the follower assembly 11, the clamping assembly 12 and the locking assembly 13 are all located in the accommodating cavity 100, and the clamping assembly 12 presses the conductive body 20 against the cavity wall of the accommodating cavity 100 in the accommodating cavity 100, during the use of the terminal 1, the follower assembly 11, the clamping assembly 12 and the locking assembly 13 can be protected by the shell 10 to avoid the situation where the clamping effect of the clamping assembly 12 on the conductive body 20 fails due to the influence of the external environment, or the locking effect of the locking assembly 13 on the first locking piece 111 fails, so as to make the connection reliability between the terminal 1 and the wire 2 better.

[0056] Optionally, a terminal conductive member (not shown) may be connected to the side of the wiring clamp 121 away from the sleeve 110 along the first direction S1. When the wiring clamp 121 moves along the second direction S2, the terminal conductive member always maintains electrical conduction with the wiring clamp 121, and the end of the terminal conductive member away from the wiring clamp 121 extends to the outside of the housing 10 so as to be electrically connected to an external circuit. For example, the terminal conductive member may include a flexible wire that can undergo a certain deformation so that the end of the terminal conductive member connected to the wiring clamp 121 can move with the wiring clamp 121. Alternatively, one end of the terminal conductive member may have an end surface extending along the second direction S2. When the wiring clamp 121 moves along the second direction S2, it can always abut against the end surface to be electrically connected to the terminal conductive member.

[0057] Please combine Figure 5 As shown, optionally, the clamping assembly 12 may include two first transmission mechanisms 120. Along the third direction S3, the two first transmission mechanisms 120 are arranged at intervals, and the wiring clamping member 121 is connected between the two first transmission mechanisms 120, so that the driving force applied by the first transmission mechanism 120 to the wiring clamping member 121 is more balanced, and the wiring clamping member 121 can be more stably clamped to the conductive body 20.

[0058] It is understood that the first transmission mechanism 120 only needs to be able to convert the sliding movement of the sleeve 110 in the first direction S1 into sliding movement in the second direction S2, so that when the insulating sheath 21 abuts the sleeve 110 and slides in the first direction S1, the wiring clamping member 121 can be driven to slide in the second direction S2 to press the conductive body 20 against the wall of the accommodating cavity 100. The specific structure of the first transmission mechanism 120 can be variously configured. Two specific structures of the first transmission mechanism 120 that can achieve the above-mentioned functions will be described below with reference to the accompanying drawings.

[0059] like Figures 3 to 6 As shown, an optional embodiment, the follower assembly 11 further includes a first rack 112, the first rack 112 and the first locking member 111 are spaced apart and arranged on the outer periphery of the sleeve 110, and the first rack 112 extends from the sleeve 110 along the first direction S1 away from the first insertion hole 101, the first transmission mechanism 120 includes a gear structure 1201 and a second rack 1202, the second rack 1202 and the first rack 112 are both engaged with the gear structure 1201, the second rack 1202 is slidably connected to the housing 10 along the second direction S2, and the second rack 120 2 is fixedly connected to the wiring clamping member 121, so that the sliding motion along the first direction S1 output by the first rack 112 can be received through the gear structure 1201, and the motion is converted into a rotational motion of the gear structure 1201, and then the rotational motion is converted into a sliding motion along the second direction S2 through the second rack 1202. Therefore, while the insulating sheath 21 pushes the sleeve 110 to slide toward the compression assembly 12 along the first direction S1, the wiring clamping member 121 is driven by the second rack 1202 to be pressed against the conductive body 20 along the second direction S2.

[0060] Optionally, the gear structure 1201 may include a first gear 1201a and a second gear 1201b that are coaxial and fixedly connected, the first rack 112 is engaged with the first gear 1201a, and the second rack 1202 is engaged with the second gear 1201b, so that the first rack 112 and the second rack 1202 are staggered along the axial direction of the gear structure 1201, so that the activity space of the first rack 112 and the second rack 1202 are staggered, thereby avoiding interference between the first rack 112 and the second rack 1202 during the use of the terminal 1.

[0061] Optionally, the follower assembly 11 may also include a first connecting member 113, which is spaced apart from the first locking member 111 on the outer periphery of the sleeve 110, and the first connecting member 113 is slidably connected to the shell 10 along the first direction S1. The first rack 112 is provided on the first connecting member 113, so that the relative sliding direction of the first rack 112 and the shell 10 can be limited by the sliding connection relationship between the first connecting member 113 and the shell 10, so that the sliding movement of the first rack 112 can be more controllable.

[0062] Furthermore, the first connecting member 113 may include a first portion 113a and a second portion 113b, the first portion 113a and the first locking member 111 are spaced apart and arranged on the outer periphery of the sleeve 110, the second portion 113b is connected to the side of the first portion 113a away from the sleeve 110, the second portion 113b is slidably connected to the housing 10 along the first direction S1, the first rack 112 is connected to the outer periphery of one end of the second portion 113b along the third direction S3, and along the third direction S3, the size of the first portion 113a is smaller than that of the second portion 113b. 13b, so that along the third direction S3, the end of the second part 113b can be further away from the hole axis of the second hole 110a, so that the first rack 112, the gear structure 1201 and the second rack 1202 can all be further away from the hole axis of the second hole 110a, thereby avoiding the problem that the first rack 112, the gear structure 1201 and the second rack 1202 hinder the end of the conductive body 20 from extending into the space between the wiring clamping member 121 and the cavity wall of the accommodating cavity 100. The third direction S3 is perpendicular to the first direction S1 and the second direction S2.

[0063] It can be understood that when the clamping assembly 12 includes two first transmission mechanisms 120 as described in the above technical solution, the two second racks 1202 of the two first transmission mechanisms 120 can be respectively connected to two opposite sides of the wiring clamping member 121 along the third direction S3.

[0064] like Figure 7As shown, another option is that the first transmission mechanism 120 includes a first connecting rod 1203, a second connecting rod 1204, a third connecting rod 1205 and a slider 1206, one end of the first connecting rod 1203 is hinged to the sleeve 110, two opposite ends of the second connecting rod 1204 are hinged to the other end of the first connecting rod 1203 and one end of the third connecting rod 1205, and the middle part of the second connecting rod 1204 is hinged to the housing 10, the other end of the third connecting rod 1205 is hinged to the slider 1206, the slider 1206 is fixedly connected to the wiring clamping member 121, and the slider 1206 moves along the second direction. It is slidably connected to the shell 10 in the direction S2, so that it can receive the sliding movement along the first direction S1 output by the first rack 112 through one end of the first connecting rod 1203, and convert the movement into the rotation of the first connecting rod 1203 and the second connecting rod 1204, thereby driving the third connecting rod 1205 to move, so as to drive the slider 1206 to slide along the second direction S2, so that the insulating skin 21 can push the sleeve 110 to slide along the first direction S1 toward the clamping assembly 12, and at the same time, the wiring clamping member 121 can be driven by the slider 1206 to be pressed against the conductive body 20 along the second direction S2.

[0065] It can be understood that when the pressing assembly 12 includes two first transmission mechanisms 120 as described in the above technical solution, the two sliders 1206 of the two first transmission mechanisms 120 are respectively connected to two opposite sides of the wiring pressing member 121 along the third direction S3.

[0066] Optionally, the wiring clamping piece 121 has a connected clamping surface 121a and a guide surface 121b, and the guide surface 121b is located on the side of the clamping surface 121a close to the sleeve 110. The guide surface 121b is used to guide the conductive body 20 to move to a part located between the clamping surface 121a and the shell 10, so that the operator can more easily insert the wire 2 into the first jack 101 and the conductive body 20 into the second jack 110a, so that the end of the conductive body 20 can easily enter between the clamping surface 121a and the cavity wall of the accommodating cavity 100, so that the wiring clamping piece 121 can effectively compress and connect the conductive body 20 between the clamping surface 121a and the cavity wall of the accommodating cavity 100.

[0067] like Figures 2 to 5As shown, optionally, the accommodating cavity 100 may include a first cavity 100a, a second cavity 100b and a third cavity 100c which are connected in sequence, and the wiring clamping member 121 can be movably arranged in the first cavity 100a, and the wiring clamping member 121 can press the conductive body 20 against the cavity wall of the first cavity 100a along the second direction S2. Along the second direction S2, the first cavity 100a and the third cavity 100c are separated, and the second cavity 100b has a first jack 101. The follower assembly 11 and the first transmission mechanism 120 are arranged in the second cavity 100b, and the locking assembly 13 is arranged in the third cavity 100c. Thus, the setting position of the locking assembly 13 and the wiring clamping member 121 can be made more compact to avoid the terminal 1 from being too long along the first direction S1.

[0068] Specifically, the locking assembly 13 may include a second locking member 130 and a first elastic member 131. The second locking member 130 can be movably arranged in the third cavity 100c. The end of the first locking member 111 away from the first socket 101 can follow the sleeve 110 to move into the third cavity 100c to be opposite to the second locking member 130. The first elastic member 131 is connected between the second locking member 130 and the cavity wall of the third cavity 100c. The first elastic member 131 is used to apply elastic force to the second locking member 130 so that the second locking member 130 can be pressed against the first locking member 111 to prevent the first locking member 111 from moving along the first direction S1 toward the first socket 101.

[0069] Optionally, one side of the first locking member 111 has a first toothed portion 1110, the first toothed portion 1110 has a first guide surface 1110a facing the sleeve 110, the first guide surface 1110a forms an angle α with the first direction S1, 90°<α<180°, the first toothed portion 1110 further has a first locking surface 1110b facing away from the sleeve 110, the first locking surface 1110b forms an angle β with the first direction S1, 90°≤β<180°, and one side of the second locking member 130 has a second toothed portion 1301, the second toothed portion 1302 forms an angle β with the first direction S1, 90°≤β<180°. 1301 has a second guide surface 1301a facing away from the sleeve 110, the second guide surface 1301a is parallel to the first guide surface 1110a, and the second guide surface 1301a can abut against the first guide surface 1110a, the second toothed portion 1301 also has a second locking surface 1301b facing toward the sleeve 110, the second locking surface 1301b is parallel to the first locking surface 1110b, and the second locking surface 1301b can abut against the first locking surface 1110b, so that when the first locking member 111 pushes the sleeve 110 along with the insulating skin 21, 0, and when sliding away from the first insertion hole 101 along the first direction S1, the first guide surface 1110a and the second guide surface 1301a can abut against each other, so that the second locking member 130 is subjected to a certain pushing force in the direction away from the first locking member 111. When the pushing force is greater than the elastic force applied by the first elastic member 131, the second locking member 130 moves in the direction away from the first locking member 111, so that the second locking member 130 does not hinder the sliding movement of the first locking member 111 away from the first insertion hole 101 along the first direction S1. After the tightening member 121 is pressed against the conductive body 20, the sleeve 110 and the first locking member 111 no longer slide along the first direction S1 away from the first socket 101. At this time, the second locking surface 1301b can abut against the first locking surface 1110b, so that the thrust exerted on the second locking member 130 is parallel to the first direction S1, or the second locking member 130 is subjected to a certain thrust directed toward the first locking member 111, so that the second locking member 130 can stably prevent the first locking member 111 from moving along the first direction S1 toward the first socket 101.

[0070] It can be understood that as long as the first locking member 111 and the second locking member 130 are in contact with each other, the second locking member 130 can be used to prevent the first locking member 111 from moving along the first direction S1 toward the first socket 101. There can be a variety of different specific setting schemes for the specific structure of the first locking member 111 and the second locking member 130. For example, in other embodiments, the surfaces of the first locking member 111 and the second locking member 130 that can be pressed against each other can have a larger friction coefficient, so that when the first locking member 111 and the second locking member 130 are pressed against each other, the friction force generated between the first locking member 111 and the second locking member 130 can also be used to prevent the first locking member 111 from moving along the first direction S1 toward the first socket 101, thereby achieving the effect of locking the first locking member 111.

[0071] like Figure 2 、 Figure 3 、 Figure 4 as well as Figure 8 As shown, optionally, the accommodating cavity 100 further includes a fourth cavity 100d connected to the third cavity 100c, the terminal block 1 further includes an unlocking assembly 14, the unlocking assembly 14 includes an operating end 140a and a second transmission mechanism 141, the operating end 140a is located outside the housing 10, the second transmission mechanism 141 is located in the fourth cavity 100d, and the second transmission mechanism 141 is connected to the operating end 140a, the second transmission mechanism 141 has a first connecting end 1410, the first connecting end 1410 is connected to the second locking member 130, the operating end 140a is used for the operator to move, the second transmission mechanism 141 is used to drive the first connecting end 1410 and the second locking member 130 to move under the drive of the operating end 140a, so that the second locking member 130 is away from the first locking member 111, the terminal block 1 further includes a second elastic member (not shown in the figure) ), the second elastic member is connected between the wiring clamping member 121 and the shell 10, and the second elastic member can apply an elastic force to the wiring clamping member 121, so that the wiring clamping member 121 has a tendency to move away from the conductive body 20 along the second direction S2, or the second elastic member is connected between the follower component 11 and the shell 10, and the second elastic member can apply an elastic force to the follower component 11, so that the follower component 11 has a tendency to approach the first jack 101 along the first direction S1, or, a second elastic member is connected between the wiring clamping member 121 and the shell 10, and between the follower component 11 and the shell 10, so that the wiring clamping member 121 has a tendency to move away from the conductive body 20 along the second direction S2 under the action of the elastic force of the second elastic member, and the follower component 11 has a tendency to approach the first jack 101 along the first direction S1 under the action of the elastic force of the second elastic member.

[0072] Therefore, when it is necessary to take out the wire 2, the operator can unlock the second locking member 130 and the first locking member 111 by moving the operating end 140a. At the same time, the wiring pressing member 121 slides away from the conductive body 20 along the second direction S2 under the elastic force of the second elastic member, driving the sleeve 110 to slide along the first direction S1 close to the first insertion hole 101, or the sleeve 110 slides along the first direction S1 close to the first insertion hole 101 under the elastic force of the second elastic member, driving the wiring pressing member 121 to slide away from the conductive body 20 along the second direction S2, or the wiring pressing member 121 is in the first direction S2. Under the action of the elastic force of the two elastic members, the sleeve 110 slides along the second direction S2 away from the conductive body 20, and under the action of the elastic force of the second elastic member, the sleeve 110 slides along the first direction S1 close to the first insertion hole 101, so that the sleeve 110 and the wire 2 can slide along the first direction S1 close to the first insertion hole 101, and the wire clamping member 121 can move away from the conductive body 20 along the second direction S2. In other words, the follower component 11 and the clamping component 12 can both be reset to the position when the wire 2 is not inserted, the wire clamping member 121 releases the clamping effect on the conductive body 20, and the wire 2 can be taken out of the accommodating cavity 100.

[0073] like Figure 3 、 Figure 4 、 Figure 8 and Figure 9 As shown, optionally, the unlocking assembly 14 includes two second transmission mechanisms 141 , which are arranged opposite to each other along the third direction S3 , so that the stability and reliability of the unlocking action of the unlocking assembly 14 can be improved by increasing the number of the second transmission mechanisms 141 .

[0074] Preferably, the two second transmission mechanisms 141 are symmetrically arranged, so that the unlocking force applied by the two second transmission mechanisms 141 to the second locking member 130 through the two first connection ends 1410 is more balanced and reasonable.

[0075] Optionally, the unlocking assembly 14 also includes a third connecting member 142, the third connecting member 142 having two second connecting ends 142a spaced opposite to each other along the third direction S3, and a third connecting end 142b spaced from the second connecting end 142a, the two second connecting ends 142a are respectively connected to the two first connecting ends 1410 of the two second transmission mechanisms 141, and the third connecting end 142b is connected to the second locking member 130, so that it can receive the unlocking force output by the two first connecting ends 1410 of the two second transmission mechanisms 141 through the third connecting member 142, and transmit the unlocking force to the second locking member 130, so that the second locking member 130 moves in the direction away from the first locking member 111 following the two first connecting ends 1410 through the third connecting member 142.

[0076] Optionally, after the operator's operating force on the operating end 140a disappears, the second locking member 130 can be reset under the action of the elastic force of the first elastic member 131, and the first connecting end 1410 of the second transmission mechanism 141 can follow the second locking member 130 to reset, so as to drive the overall structure of the second transmission mechanism 141 and the operating end 140a to reset.

[0077] Preferably, a third elastic member 143 may be connected between the second transmission mechanism 141 and the shell 10. The third elastic member 143 can apply an elastic reset force to the second transmission mechanism 141, so that after the operator's operating force on the operating end 140a disappears, the second transmission mechanism 141 as a whole and the operating end 140a are reset by the third elastic member 143, thereby improving the reliability of the reset process of the unlocking component 14.

[0078] It is understood that the second transmission mechanism 141 only needs to be able to move the second locking member 130 away from the first locking member 111 when the operating end 140a is moved by the operator, thereby unlocking the second locking member 130 from the first locking member 111. The specific structure of the second transmission mechanism 141 can be arranged in a variety of different ways. The following will exemplify three specific structures of the second transmission mechanism 141 that can achieve the above-mentioned functions, with reference to the accompanying drawings.

[0079] like Figures 8 to 10As shown, optionally, along the second direction S2, the operating end 140a is located on one side of the housing 10, and the operating end 140a is located on the side of the second locking member 130 away from the first locking member 111, the operating end 140a is used for the operator to press along the second direction S2, the unlocking assembly 14 also includes an operating rod 140, the operating rod 140 is slidably connected to the housing 10 along the second direction S2, the operating rod 140 has relative operating ends 140a and a driving end 140b, the second transmission mechanism 141 includes a transmission rod 141a, a sliding sleeve 141b and a second connecting member 141c, one end of the transmission rod 141a is hinged to the driving end 140b, the middle part of the transmission rod 141a is hinged to the housing 10, the outer periphery of the other end of the transmission rod 141a is slidably sleeved with a sliding sleeve 141b, the sliding sleeve 141b is hinged to the second connecting member 141c, and the second connecting member 141c is slidably connected to the housing 1 along the second direction S2. 0, the second connecting member 141c has a first connecting end 1410, so that when the operator presses the operating end 140a toward the housing 10 along the second direction S2, the driving end 140b drives one end of the transmission rod 141a to move along the second direction S2 toward the first locking member 111. Since the middle part of the transmission rod 141a is hinged to the housing 10, the other end of the transmission rod 141a is away from the first locking member 111, driving the sliding sleeve 141b along the second direction S2 away from the first locking member 111. At this time, the sliding sleeve 141b also slides relative to the transmission rod 141a along the extension direction of the transmission rod 141a. The second connecting member 141c is driven by the sliding sleeve 141b to move away from the first locking member 111 along the second direction S2, thereby driving the second locking member 130 along the second direction S2 away from the first locking member 111 through the first connecting end 1410, so that the second locking member 130 is unlocked from the first locking member 111.

[0080] Optionally, the second transmission mechanism 141 may further include a limiting sliding member 141d, the limiting sliding member 141d and the second connecting member 141c are respectively hinged to the two opposite sides of the sliding sleeve 141b, and the limiting sliding member 141d can be slidably connected to the shell 10 along the second direction S2, so that the sliding movement direction of the sliding sleeve 141b relative to the shell 10 can be jointly limited by the limiting sliding member 141d and the second connecting member 141c, so that the controllability and reliability of the sliding movement of the sliding sleeve 141b relative to the shell 10 along the second direction S2 are better.

[0081] Optionally, an avoidance groove 140c may be provided in the middle of the driving end 140b along the radial direction of the operating rod 140, one end of the transmission rod 141a extends into the avoidance groove 140c, and both sides of the transmission rod 141a along the radial direction are hinged to the driving end 140b, so that the transmission balance of the acting force between the driving end 140b and the transmission rod 141a is better, which is conducive to making the transmission action between the operating rod 140 and the transmission rod 141a more reliable, and by providing the avoidance groove 140c, the structure of the transmission rod 141a can be avoided, and activity space is reserved for the situation where the transmission rod 141a rotates relative to the driving end 140b.

[0082] When, as in the aforementioned technical solution, a third elastic member 143 is also connected between the second transmission mechanism 141 and the shell 10, for example, a third elastic member 143 may be connected between the driving end 140b and the shell 10, so that after the operator's operating force on the operating end 140a disappears, the third elastic member 143 drives the operating rod 140 to slide along the second direction S2, so that the operating end 140a moves and resets in the direction away from the shell 10, and the operating end 140a drives the transmission rod 141a, the sliding sleeve 141b and the second connecting member 141c to reset.

[0083] like Figure 11 As shown, another option is that along the second direction S2, the operating end 140a is located on one side of the shell 10, and the operating end 140a is located on the side of the second locking member 130 close to the first locking member 111, and the operating end 140a is used for the operator to press along the second direction S2, so that when the operator presses the operating end 140a toward the shell 10 along the second direction S2, the second transmission mechanism 141 as a whole follows the operating end 140a to move along the second direction S2 toward the direction away from the first locking member 111, driving the second locking member 130 along the second direction S2 away from the first locking member 111, so that the second locking member 130 is unlocked from the first locking member 111.

[0084] like Figure 12 As shown, another option is that the operating end 140a is located on one side of the housing 10 along the first direction S1 or the third direction S3, and the operating end 140a is used for the operator to move it along the second direction S2. The middle part of the second transmission mechanism 141 is hinged to the housing 10, so that when the operator moves the operating end 140a in the direction close to the first locking member 111 along the second direction S2, the first connecting end 1410 of the second transmission mechanism 141 moves in a direction away from the first locking member 111 under the seesaw principle, thereby driving the second locking member 130 away from the first locking member 111, so that the second locking member 130 is unlocked from the first locking member 111, wherein, Figure 12Taking the operating end 140 a located on one side of the housing 10 along the first direction S1 as an example, a structure of the housing 10 , the first locking member 111 , the locking assembly 13 and the unlocking assembly 14 is exemplarily shown.

[0085] It should be noted that when the aforementioned components are slidably connected to the shell 10 along one direction, a slide groove extending along the one direction can be provided on the shell 10, and the various components can be slidably connected to the slide groove along the one direction to achieve slidable connection with the shell 10 along one direction.

[0086] like Figure 13 As shown, the present invention further provides a terminal block 3 comprising a plurality of sequentially arranged and connected terminal blocks, at least some of which are the terminal blocks 1 described in the aforementioned technical solution. The terminal block 3 provided by the present invention, by providing the aforementioned terminal blocks 1, provides for improved tightness and reliability in the connection between the terminal block 3 and the electrical wires.
