Description

Technical Field

[0001] The invention relates to the technical field of connecting terminals, in particular to a lever type connecting terminal. Background Art

[0002] Terminal blocks are an accessory product used to achieve electrical connections, and are classified as connection terminals in the industry. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks has gradually increased. With the development of the electronics industry, the scope of use of terminal blocks has become wider and wider, and there are more and more types. Existing terminal blocks are used to facilitate the connection of wires. They are actually a piece of metal sheet sealed in insulating plastic. There are holes at both ends for inserting wires, and screws for tightening or loosening. For example, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals, and can be disconnected at any time without welding them or winding them together.

[0003] One type of terminal block is that when an external wire needs to be connected to the terminal block during use, the user needs to press an operating button so that the operating button opens the wire clamping connector to leave a gap for the wire to be inserted. After the wire is inserted into the gap, the user releases the pressure on the operating button, and the wire located in the gap can be clamped with the help of the elastic restoring force of the wire clamping connector, thereby achieving electrical connection between the wire and the electrical contact element, and completing the wiring operation of the terminal block.

[0004] The traditional way of using the above-mentioned terminal blocks is to refer to Fig. 9 , use a screwdriver or other tool to push open the internal elastic part through the operating hole to make room for the wire to be inserted. After the wire is inserted, remove the screwdriver and the elastic part will automatically reset to compress the wire. Alternatively, refer to Fig.10 , you need to use a screwdriver to unscrew the screws first, then disassemble the shell, and then connect the wires. The above method has obvious disadvantages, for example: first, you must use tools, if you don't have tools at hand, you can't do the plug-in and unplug wiring operations; second, the operation is unstable, which can easily cause damage to internal elastic parts, shells and other components, reducing the service life of the product.

[0005] In another type of connection terminal, the push rod is an integrated structure. When the push rod is rotated to release the lock and the spring is released, the impact of the elastic force of the elastic component rebounding instantly on the push rod is not considered. When the push rod encounters a large impact, the operating end of the push rod may cause harm to the operator.

[0006] Therefore, there is an urgent need to improve the existing wiring terminal structure so as to facilitate users to plug and unplug cables without the aid of tools. Summary of the invention

[0007] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a lever type terminal.

[0008] The technical solution of the present invention to solve the technical problem is: a lever-type terminal, comprising:

[0009] An insulating housing is provided with a wire insertion hole and a terminal hole, and the insulating housing has a receiving cavity connected to the wire insertion hole and the terminal hole;

[0010] A conductive member, which is disposed in the accommodating cavity, and at least part of the conductive member extends out of the insulating housing through the terminal hole;

[0011] An elastic clamping member is arranged in the accommodating cavity and has a movable end and a fixed end, wherein the movable end is used to press the wire entering the accommodating cavity from the wire insertion hole onto the conductive member, and the fixed end is always in contact with the conductive member;

[0012] A transmission slider is movably arranged in the accommodating cavity and is located between the operating member and the movable end of the elastic clamping member;

[0013] The operating member has an upward protruding end, a connecting end and a downward pressing end from front to back, wherein the upward protruding end extends out of the insulating shell, the connecting end is rotatably connected with the insulating shell, and the downward pressing end can extend into the accommodating cavity and cause the movable end of the elastic clamp to deform through a transmission slider, thereby forming an insertion gap between the movable end and the conductive member for the wire to pass through.

[0014] The above technical solution is further configured as follows: guide blocks are protruding from both side walls of the accommodating cavity, and the guide blocks have a front guide end face and a rear limit end face;

[0015] A vertical movable channel is formed between the front guide end surface and the hole wall of the wire plug-in hole, and the transmission sliding block is slidably arranged in the movable channel.

[0016] The above technical solution is further configured as follows: the elastic clamping member includes a clamping member base, the movable end is formed by extending outward from one end of the clamping member base, and the movable end always has an elastic movement tendency to approach the conductive member;

[0017] The movable end comprises a crimping portion and a driven portion arranged on both sides of the crimping portion, and the transmission sliding block acts on the driven portion.

[0018] The above technical solution is further configured as follows: the conductive part includes a conductive sheet body, and a first contact portion and a second contact portion protruding from the conductive sheet body; the inner end of the first contact portion forms a contactable connection with the crimping portion, and the outer end of the first contact portion extends to the outside of the insulating shell through the terminal hole; the inner end of the second contact portion forms a contactable connection with the fixed end of the elastic clamp, and the outer end of the second contact portion extends to the outside of the insulating shell through the terminal hole.

[0019] The above technical solution is further configured as follows: a limiting column is protruding from the cavity wall of the accommodating cavity, the clamp base is sleeved on the circumferential side of the limiting column, the fixed end is formed by extending outward from the other end of the clamp base, the fixed end protrudes to the side to form a positioning block, the conductive sheet body is stuck and has a positioning slot, and the positioning block is inserted into the positioning slot.

[0020] The above technical solution is further configured as follows: the transmission slider includes a transverse section and a vertical driving section formed by folding both ends of the transverse section downward, and the vertical driving section is positioned relative to the driven part and forms a contactable connection.

[0021] The above technical solution is further configured as follows: the inner end of the first contact portion extends inward to form a wedge-shaped stop surface, a stop groove is provided on the inner wall of the wire insertion hole, the wedge-shaped stop surface passes through the gap between the two vertical drive sections and extends into the stop groove, and a vertical movable stroke of the transmission slider is formed between the wedge-shaped stop surface and the transverse section.

[0022] The above technical solution is further configured as follows: an inclined guide surface is provided on the transverse section near the downward pressing end, and the downward pressing end has an arc-shaped conduction surface. When the operating member is lifted up, the arc-shaped conduction surface contacts the inclined guide surface and causes the transmission slider to move.

[0025] The method of using the present invention is as follows: when it is necessary to plug or unplug a wire, the user aligns the operating member and lifts the raised end of the operating member upward, so that the entire operating member rotates with the connection end as the rotation center, and the downward pressure end opposite the raised end moves downward through the movement of the lever. During the downward movement, the downward pressure end contacts the transmission slider and transmits the force to the movable end of the elastic clamping member through the transmission slider, and then the movable end is deformed and moved, so that the movable end moves away from the conductive member, so that an insertion gap is formed between the two. At this time, the wire can be inserted or the originally fixed wire can be released and removed. The user releases the operating member, and the elastic clamping member returns to its initial position under the action of its own elastic force. Finally, if it is in the wiring state, the conductive member is plugged together with the external circuit to achieve conduction of the front and rear circuits.

[0026] The beneficial effects of the present invention are: 1. By improving and optimizing the structure, there is no need to use external tools such as screwdrivers. By adopting the lever principle, an insertion gap for the wire to be inserted / removed can be formed between the elastic clamping member and the conductive member through the operating member and the transmission slider, so as to achieve faster and easier wiring action, effectively reduce the operating difficulty and save a lot of time when connecting and releasing the wires; 2. The specific shapes and structures of the operating member, the transmission slider, the elastic clamping member, and the conductive member are optimized and designed, so that the four are subjected to more balanced force when working, provide anti-deformation ability, improve the reliability and service life of the components, and thus maintain the long-term stability of the contacts.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Reference Figures 1 to 8 , a lever type terminal, comprising:

[0040] An insulating housing 1 is provided with a wire insertion hole 5 and a terminal hole 6, wherein the insulating housing 1 has a receiving cavity 7 connected to the wire insertion hole 5 and the terminal hole 6;

[0041] The conductive member 4 is disposed in the accommodating cavity 7, and at least a portion of the conductive member 4 extends out of the insulating housing 1 through the terminal hole 6;

[0042] An elastic clamp 3 is disposed in the accommodating cavity 7 and has a movable end 8 and a fixed end 9. The movable end 8 is used to press the wire entering the accommodating cavity 7 from the wire insertion hole 5 onto the conductive member 4, and the fixed end 9 is always in contact with the conductive member 4.

[0043] A transmission slider 14 is movably disposed in the accommodating cavity 7 and is located between the operating member 2 and the movable end 8 of the elastic clamping member 3;

[0044] The operating member 2 has an upper end 10, a connecting end 11 and a pressing end 12 from front to back, wherein the upper end 10 extends out of the insulating shell 1, the connecting end 11 forms a rotational connection with the insulating shell 1, and the pressing end 12 can extend into the accommodating cavity 7 and cause the movable end 8 of the elastic clamp 3 to deform through the transmission slider 14, thereby forming an insertion gap 13 for the wire to pass through between the movable end 8 and the conductive member 4.

[0045] The above content is the basic scheme of the present invention, in which the operating member 2 adopts the lever-type structural principle. When it is necessary to plug or unplug the wire, the user lifts up the upper end 10 of the operating member 2 so that the entire operating member 2 rotates with the connecting end 11 as the rotation center, so that the lower pressure end 12 opposite to the upper end 10 moves downward. During the downward movement, the lower pressure end 12 contacts the transmission slider 14 and transmits the force to the movable end 8 of the elastic clamp 3 through the transmission slider 14, and then the movable end 8 is deformed and moved, so that the movable end 8 moves away from the conductive member 4, so that an insertion gap 13 is formed between the two. At this time, the wire can be inserted or the originally fixed wire can be released and taken out. Finally, the user releases the operating member 2, and the elastic clamp 3 returns to its initial position under the action of its own elastic force.

[0046] Among them, the conductive part 4 is not fixedly connected by screws, buckles or other methods during installation, so if a certain degree of deflection occurs during use, it may not be able to achieve normal functions. The countermeasures adopted by the present invention are as follows: guide blocks 15 are convexly provided on the cavity walls on both sides of the accommodating cavity 7, and the guide blocks 15 have a front guide end face 16 and a rear limit end face 17; a vertical movable channel 18 is formed between the front guide end face 16 and the hole wall of the wire plug hole 5, and the transmission slider 14 is slidably arranged in the movable channel 18. Through the cooperation between the front guide end face 16 and the hole wall of the wire plug hole 5, a vertical movable channel 18 is formed, and then the transmission slider 14 can only move up and down in the movable channel 18 according to its specific trajectory, so as to ensure that the transmission slider 14 will not be dislocated, so that its cooperation with the operating member 2 and the elastic clamp 3 is stable and reliable. The conductive part 4 will inevitably still have a certain amount of jumping during use, but it is effectively limited between the rear limiting end face 17 of the guide block 15 and the inner cavity wall on the rear side of the accommodating cavity 7. Therefore, even if jumping occurs, it can be maintained in the effective working area to perform its function normally.

[0047] The elastic clamp 3 is generally made of copper metal, which not only meets the electrical conductivity requirements, but also has a certain amount of deformation and plasticity. If the structure of the movable end 8 is not specially designed, the defect is that after repeated use and deformation, the movable end 8 will experience product fatigue, and then fail to return to its original position after deformation, so that the clamping force of the movable end 8 on the wire decreases, and it is easy to get loose and have poor contact. In order to solve the above defects, a preferred structure of the elastic clamp 3 is as follows: the elastic clamp 3 includes a clamp base 19, the movable end 8 is formed by extending outward from one end of the clamp base 19, and the movable end 8 always has an elastic movement tendency close to the conductive member 4; the movable end 8 has a crimping portion 20 and a driven portion 21 arranged on both sides of the crimping portion 20, and the transmission slider 14 acts on the driven portion 21. Firstly, by setting the crimping part 20 and the driven part 21, the functions of the active end 8 are partitioned; also by the partitioned setting of the crimping part 20 and the driven part 21, the path of force conduction is restricted, so that the product fatigue occurring at the active end 8 is concentrated on the driven part 21, so as to reduce the product fatigue of the crimping part 20, so that the crimping part 20 can be used stably and reliably for a long time.

[0048] The specific structure of the conductive member 4 is as follows: the conductive member 4 includes a conductive sheet body 22, and a first contact portion 23 and a second contact portion 24 protruding from the conductive sheet body 22; the inner end of the first contact portion 23 forms a contactable connection with the crimping portion 20, and the outer end (first welding leg 25) of the first contact portion 23 extends out of the insulating housing 1 through the terminal hole 6; the inner end of the second contact portion 24 forms a contactable connection with the fixed end 9 of the elastic clamp 3, and the outer end (second welding leg 26) of the second contact portion 24 extends out of the insulating housing 1 through the terminal hole 6. The first welding leg 25 and the second welding leg 26 are connected to external electrical components to achieve power supply.

[0049] In some preferred configurations of the present invention, a limiting column 27 is protruded from the cavity wall of the accommodating cavity 7, and the clamping member base 19 is sleeved on the circumference of the limiting column 27. The limiting column 27 can effectively limit the clamping member base 19, thereby making the movement of the elastic clamping member 3 more regular and stable. On the other hand, since the elastic clamping member 3 is movably arranged in the cavity, but for the stability of the movement of the movable end 8, it is necessary to form a good limiting function based on the fixed end 9. The method adopted in this embodiment is: the fixed end 9 is formed by extending outward from the other end of the clamping member base 19, and the fixed end 9 protrudes to the side to form a positioning plug 28, and a positioning slot 29 is provided on the conductive sheet body 22, and the positioning plug 28 is inserted into the positioning slot 29. Through the plug-in cooperation of the positioning plug 28 and the positioning slot 29, the fixed end 9 of the elastic fixing member and the conductive sheet body 22 of the conductive member 4 form a good limiting function between each other without relying on the insulating shell 1.

[0050] The shape and structure of the transmission slider 14 are specially designed, including a transverse section 30 and a vertical driving section 31 formed by folding both ends of the transverse section 30 downwards. The vertical driving section 31 is opposite to the driven part 21 and forms a contactable connection.

[0051] The inner end of the first contact portion 23 extends inward to form a wedge-shaped stop surface 32, and a stop groove 33 is formed on the inner wall of the wire insertion hole 5. The wedge-shaped stop surface 32 passes through the gap between the two vertical driving sections 31 and extends into the stop groove 33, and a vertical movable stroke 34 of the transmission slider 14 is formed between the wedge-shaped stop surface 32 and the transverse section 30. First, through the cooperation between the wedge-shaped stop surface 32 and the stop groove 33, the lateral installation position of the conductive sheet body 22 is effectively limited, and the wedge-shaped contact surface can increase the contact area, making the cooperation tighter and more stable and reliable during installation; secondly, the above method not only provides sufficient position stability for the first contact portion 23, but also through the extension setting of the first contact portion 23, it ensures that the wire is clamped by cooperating with the elastic clamp 3; furthermore, the vertical active stroke 34 formed between the wedge-shaped stop surface 32 and the lateral section 30 can play a good vertical limiting role for the moving transmission slider 14, preventing it from excessive vertical movement and causing it to be unable to be used normally; in addition, the wedge-shaped stop surface 32 passes through the gap between the two vertical drive sections 31, and this structure effectively limits the longitudinal position of the transmission slider 14. Once the transmission slider 14 is longitudinally offset, it will contact the two side walls of the wedge-shaped stop surface 32, playing a role of limiting and timely correcting.

[0052] A further preferred configuration of the present invention is as follows: an inclined guide surface 35 is provided on the transverse section 30 near the pressing end 12, and the pressing end 12 has an arc-shaped conductive surface 36. When the operating member 2 is lifted, the arc-shaped conductive surface 36 contacts the inclined guide surface 35 and causes the transmission slider 14 to move. Through the cooperation of the inclined guide surface 35 and the arc-shaped conductive surface 36, the contact and transmission cooperation between the operating member 2 and the transmission slider 14 are smoother and more comfortable to operate.

[0053] The above technical solution is further configured as follows: an inclined "W"-shaped transition section 37 is provided between the clamp base 19 and the movable end 8, and a portion a of the transition section 37 close to the clamp base 19 is in contact with the wall of the inner cavity, and a portion b of the transition section 37 away from the clamp base 19 is suspended in the inner cavity. With the above structural solution, firstly, a portion b of the transition section 37 is suspended in the air to obtain sufficient deformation space to ensure the movable end 8's movement requirements; secondly, another portion a of the transition section 37 is in contact with the wall of the inner cavity, and the wall of the inner cavity provides a certain supporting force, which, combined with the overall "W" shape, can better disperse the pressure, thereby providing the elastic clamp 3 with the ability to resist deformation and improving the reliability and service life of the component.

[0054] Multiple wiring terminals are often used side by side to connect / lead out more circuits. Therefore, this embodiment also provides a special structure of an insulating shell 1, which can realize any number of splicing combinations to meet the usage requirements of different users. Specifically: the insulating shell 1 includes a main shell 38 and a side sealing plate 39, the main shell 38 has a closed side 40 and an open side 41, the open side 41 is assembled with the side sealing plate 39 or the closed side 40 of another main shell 38 to form the accommodating cavity 7.

[0055] Furthermore, in order to automatically and quickly reset the operating member 2 after use, an elastic reset member (not shown in the figure) is provided between the operating member 2 and the conductive member 4. The elastic reset member is preferably a torsion spring, which acts on the connecting end 11 of the operating member 2.

[0056] Furthermore, a test hole 42 penetrating the operating member 2 is provided on the top of the operating member 2 , and the test hole is located directly above the conductive member 4 , so as to facilitate rapid detection of the internal circuit without disassembling the insulating housing 1 .

[0057] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment according to the technical essence of the invention still falls within the protection scope of the technical solution of the present invention.
