Technical Field

[0001] The invention belongs to the technical field of connectors, and more particularly relates to a pluggable terminal. Background Art

[0002] With the development of the electronics industry, terminal blocks, as accessories for achieving electrical connections, are becoming increasingly widely used and diverse. When connecting indoor and outdoor equipment, specialized terminal blocks are used. These blocks, when combined, are called terminal blocks. The function of a terminal block is to connect the circuits between indoor and outdoor equipment, facilitating signal (current and voltage) transmission.

[0003] However, the existing terminal blocks have a complex structure and are not easy to manufacture. Moreover, tools are required to connect and remove the wires during the wiring process, which makes the operation more troublesome. Therefore, there is still room for improvement. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention aims to provide a pluggable terminal block having the advantages of simple structure and easy operation.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a plug-in terminal, comprising a base and a conductive combination arranged in the base, a wire insertion hole for the wire to be inserted is provided on one side of the base, the conductive combination comprises a terminal body with an accommodating space and a spring arranged in the accommodating space, the spring sheet is bent into shape near one end of the wire insertion hole and forms a clamp for clamping the wire with the upper end of the terminal body.

[0006] By adopting the above technical solution, when in use, the wire can be effectively clamped and the electrical connection can be achieved by simply passing the wire through the wire insertion hole until the wire passes through the clamping opening and is clamped between the spring piece and the terminal body. In summary, the cooperation between the spring piece and the terminal body allows the connection of the wires without the use of tools, which is convenient to operate and has a simple structure.

[0007] The present invention is further configured as follows: the elastic sheet includes a mounting portion that is clamped with the bottom of the accommodating space and a wire pressing portion that abuts against the upper end of the terminal body and forms the clamping opening.

[0008] By adopting the above technical solution, during assembly, the spring piece can be connected to the terminal body through the installation portion, and the clamping opening for clamping the wire can be formed through the wire pressing portion.

[0009] The present invention is further configured as follows: a limiting block protruding upward is provided at the bottom of the accommodating space, and a limiting hole for the limiting block to pass through is provided on the mounting portion.

[0010] By adopting the above technical solution, during assembly, the cooperation between the limiting block and the limiting hole can limit the axial displacement of the mounting portion, effectively preventing the spring from separating from the terminal body.

[0011] The present invention is further configured as follows: extending retaining plates are provided on both sides of the mounting portion away from one end of the wire insertion hole, and a retaining portion abutting against the retaining plates is provided on the terminal body.

[0012] By adopting the above technical solution, under the cooperation of the locking plate and the locking portion, the installation portion can be easily inserted but difficult to be removed, further preventing the spring sheet from separating from the terminal body.

[0013] The present invention is further configured such that: the mounting portion and the wire pressing portion are connected via a bending portion.

[0014] By adopting the above technical solution, the setting of the bending portion can not only make the wire pressing portion more easily deformable, but also enhance the structural strength of the mounting portion and the wire pressing portion, making the wire pressing portion more stable in clamping the wire.

[0015] The present invention is further configured such that: a plurality of anti-slip grooves are provided on one side of the terminal body that abuts against the wire pressing portion.

[0016] By adopting the above technical solution, the design of the anti-slip groove can increase the friction resistance between the wire and the terminal body, preventing the wire from falling off the terminal.

[0017] The present invention is further configured as follows: a through hole is opened at the upper end of the base facing the wire pressing portion, and a pressing member is slidably provided in the through hole to abut against the upper end of the wire pressing portion.

[0018] By adopting the above technical solution, when the wire needs to be removed from the base, it is only necessary to apply downward force to the wire pressing part through the pressing piece, so that the wire pressing part produces elastic deformation and separates from the upper end of the terminal body, and the wire can be quickly pulled out.

[0019] The present invention is further configured as follows: sliding grooves perpendicular to the wire insertion direction are provided on both sides of the inner wall of the through hole, and sliders that slide in the sliding grooves extend from both ends of the pressing member.

[0020] By adopting the above technical solution, under the cooperation of the slider and the sliding groove, not only can the pressing piece be prevented from being separated from the through hole, but the pressing piece can also be moved up and down stably.

[0021] The present invention is further configured as follows: the pressing member includes a pair of pressing blocks that abut against the upper end of the wire pressing portion and a clearance channel located between the two pressing blocks and for the wire to pass through.

[0022] By adopting the above technical solution, when the pressing member applies downward force to the wire pressing portion, the pressing block presses against both sides of the upper end of the wire pressing portion, and the wire is released from the terminal through the clearance channel. The clearance channel can prevent the pressing member from affecting the wire's release from the terminal.

[0023] The present invention is further configured as follows: a buckle or a slot is provided on the inner wall of the base, and a corresponding slot or buckle is provided on the outer wall of the terminal body.

[0024] By adopting the above technical solution, during assembly, the connection between the terminal body and the base can be quickly achieved through the cooperation of the buckle and the slot, which is convenient and quick.

[0025] In summary, the present invention has the following advantages: 1. Through the cooperation between the spring and the terminal body, the wire connection can be achieved without the use of tools, which is easy to operate and has a simple structure;

[0026] 2. The anti-slip groove can increase the friction resistance between the wire and the terminal body, preventing the wire from detaching from the terminal;

[0027] 3. When the wire needs to be removed from the base, simply apply downward force to the wire pressing part through the pressing piece to cause the wire pressing part to produce elastic deformation and separate from the upper end of the terminal body, and then the wire can be quickly pulled out.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] A pluggable terminal block, such as Figure 1 、 2 As shown, it includes a base 1 and a conductive combination 2. The base 1 is a three-row terminal block. The conductive combination 2 is arranged in the base 1. A wire insertion hole 3 for the wire to pass through is provided on one side of the base 1.

[0037] like Figure 2 、 3 As shown, the conductive combination 2 includes a terminal body 21 with an accommodating space 211 and a spring piece 22 arranged in the accommodating space 211. A card slot 4 is provided on the inner wall of the base 1, and a buckle 5 corresponding to the card slot 4 is fixed to the outer wall of the terminal body 21. Through the cooperation of the buckle 5 and the card slot 4, the terminal body 21 and the base 1 can be quickly assembled. In addition, the spring piece 22 is bent and formed near one end of the wire insertion hole 3 and forms a clamp 6 for clamping the wire with the upper end of the terminal body 21. Therefore, it is only necessary to pass the wire through the wire insertion hole 3, so that the wire passes through the clamp 6 and is clamped between the spring piece 22 and the terminal body 21, so that the wire can be effectively clamped and the electrical connection can be achieved.

[0038] like Figure 2 、 3 As shown, the spring piece 22 includes a mounting portion 221 that is clamped with the bottom of the accommodating space 211 and a wire pressing portion 222 that abuts against the upper end of the terminal body 21 and forms a clamping opening 6. Figure 4 As shown, an upwardly protruding limit block 7 extends from the bottom of the accommodating space 211, and a limit hole 8 for the limit block 7 to pass through is provided on the mounting portion 221. The cooperation between the limit block 7 and the limit hole 8 can limit the axial displacement of the mounting portion 221, effectively preventing the spring piece 22 from separating from the terminal body 21. In addition, a retaining plate 9 is provided on both sides of the mounting portion 221 away from the end of the wire insertion hole 3, and a retaining portion 10 is provided on the terminal body 21 to abut against the retaining plate 9. The cooperation between the retaining plate 9 and the retaining portion 10 can make the mounting portion 221 easy to enter and difficult to exit, further preventing the spring piece 22 from separating from the terminal body 21.

[0039] Furthermore, the mounting portion 221 and the wire pressing portion 222 are connected via a bending portion 223 , which enables the wire pressing portion 222 to be more easily deformed, thereby making the wire pressing portion 222 more stable in clamping the wire.

[0040] It is worth mentioning that in order to increase the friction resistance between the wire and the terminal body 21 and effectively prevent the wire from detaching from the terminal, a plurality of anti-slip grooves 11 are provided on the side where the terminal body 21 abuts against the wire pressing portion 222 in this embodiment.

[0041] like Figure 4 、 5 As shown, the upper end of the base 1 is provided with a through hole 12 facing the wire pressing portion 222, and a pressing member 13 is slidably provided in the through hole 12 to abut against the upper end of the wire pressing portion 222. Figure 6 As shown, the inner walls of the through hole 12 are provided with grooves 14 perpendicular to the wire insertion direction, and sliders 15 extending from both ends of the pressing member 13 slide in the grooves 14. Therefore, when the wire needs to be removed from the base 1, it is only necessary to apply a downward force to the wire pressing portion 222 through the pressing member 13, causing the wire pressing portion 222 to elastically deform and separate from the upper end of the terminal body 21, so that the wire can be quickly pulled out.

[0042] like Figure 5 As shown, the pressing member 13 includes a pair of pressing blocks 131 that abut against the upper end of the wire pressing portion 222 and a clearance channel 132 located between the two pressing blocks 131 for the wire to pass through. That is, when the pressing member 13 applies a downward force to the wire pressing portion 222, the pressing blocks 131 press against both sides of the upper end of the wire pressing portion 222, and the wire is separated from the terminal through the clearance channel 132, which can effectively prevent the pressing member 13 from affecting the wire's separation from the terminal.

[0043] The working process and beneficial effects of the present invention are as follows: During use, the wire is simply passed through the wire insertion hole 3, causing the wire pressing portion 222 to deform until the wire passes through the clamping opening 6 and is clamped between the wire pressing portion 222 and the terminal body 21, effectively clamping the wire and achieving an electrical connection. When the wire needs to be removed from the base 1, a downward force is applied to the pressing member 13, causing the wire pressing portion 222 to elastically deform and move downward, thereby removing the wire.

[0044] In summary, in this embodiment, the spring piece 22 cooperates with the terminal body 21 to achieve connection and removal of the wires without using tools, which is easy to operate and has a simple structure.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
