Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a wiring terminal. Background Art

[0002] In the field of electrical connectors, terminal blocks are one of the most important parts for achieving electrical connections. They are mainly used to equip electrical cabinets or boxes of industrial machines. There are two main ways to clamp wires in general terminal blocks: one is to tighten the wires by tightening bolts; the other is to clamp the wires by springs.

[0003] The Chinese utility model patent with the authorization announcement number CN214589333U discloses a terminal block, which includes a housing and a conductive member disposed inside the housing, wherein the conductive member has contact ends extending upward at both ends, and a spring sheet is fixedly mounted on the inner wall of the housing, wherein one end of the spring sheet is a free end, and the other end of the spring sheet is a fixed end, and the free end of the spring sheet abuts against the contact end of the conductive sheet. When the conductive member and the spring sheet are installed in the housing, since the spring sheet has elastic force, and there is no limit between the spring sheet and the conductive sheet, the two are only in abutment relationship, so that when the spring sheet and the conductive sheet cooperate, the spring sheet is easy to pop out of the housing, and the installation is relatively difficult, which needs to be improved. Utility Model Content

[0004] In order to solve the problem that it is difficult to install a conductive member and a spring in a housing of a wiring terminal, the present application provides a wiring terminal.

[0005] The present application provides a terminal block, which adopts the following technical solution:

[0006] A terminal block comprises a shell, a conductive member arranged in the shell, and a spring sheet arranged in the shell and elastically abutting against the conductive member, the shell is provided with a wire socket for inserting a power line, the conductive member has a conductive end, the spring sheet comprises an elastic section abutting against the conductive end and a fixed section connected to the elastic section; the fixed section is provided with a plug-in through hole for plugging the conductive end; the conductive end is provided with a bending portion, the end of the fixed section is bent to form a limiting groove for the bending portion to be snap-fitted; the angle between the direction in which the bending portion is snapped into the limiting groove and the direction in which the conductive end is snapped into the plug-in through hole is greater than or equal to 90°.

[0007] By adopting the above technical scheme, when assembling the terminal block, the conductive part is first matched with the spring sheet, and then the conductive part and the spring sheet are installed together in the shell; the installation method of the conductive part and the spring sheet is: first insert the conductive end into the plug-in through hole, then snap the bent portion into the limiting groove, and finally make the elastic section abut against the conductive end; after the bent portion is snapped into the limiting groove, the conductive end is restricted from withdrawing from the plug-in through hole, and after the elastic section abuts against the conductive end, the bent portion is pressed into the limiting portion, further making the limiting of the spring sheet and the conductive part more stable; the spring sheet and the conductive part are installed together into the shell more firmly through the above assembly method, and under the limiting of the conductive part, the spring sheet is not easy to pop out of the shell due to its elasticity, and is relatively stable.

[0008] Optionally, an angle between a direction in which the bending portion is inserted into the limiting groove and a direction in which the conductive end is inserted into the plug-in through hole is greater than or equal to 90°.

[0009] By adopting the above technical solution, the bent portion is inserted into the limiting groove, and the direction in which the bent portion is inserted into the limiting groove is greater than or equal to 90° to the direction in which the conductive end is inserted into the plug-in through hole. The conductive end and the bent portion form a mutual limit, thereby limiting the conductive end from directly withdrawing from the plug-in through hole along its length direction. The conductive end is not easily pulled out of the plug-in through hole, so that the conductive part is installed in the shell more stably.

[0010] Optionally, the number of the bending portions is two, which are symmetrically arranged at both ends of the conductive end; the limiting groove is arranged along the entire width direction of the fixed section, or it can be two unconnected limiting grooves corresponding one-to-one to the bending portions.

[0011] By adopting the above technical solution, bending parts are provided on both sides of the conductive end, and the bending parts are limited and clamped in the limiting groove. Compared with the case where there is only one bending part, the two bending parts are provided so that the force on both sides of the conductive end is uniform, the spring sheet is not easy to fall off from the conductive part, and it is more stable.

[0012] Optionally, a limiting bend is provided at the end of the conductive end, the limiting bend is bent in a direction close to the elastic segment, and a limiting groove is formed between the limiting bend and the conductive end for the end of the elastic segment to abut and limit.

[0013] By adopting the above technical solution, when assembling the conductive part and the spring sheet, after the elastic section of the spring sheet abuts against the conductive end, the elastic section of the spring sheet always has a tendency to slide out from the end of the conductive end. However, since the limiting bend blocks the path of the elastic section sliding out of the wire end, and the end of the elastic section is simultaneously limited in the limiting groove, the end of the elastic section is not easy to slide out from the end of the conductive end, and the stability is better.

[0014] Optionally, an insertion portion is connected to the end of the limiting bend away from the conductive end, the insertion portion is bent in a direction away from the elastic section and forms an angle with the conductive end, and the insertion portion forms a limit with the fixed section.

[0015] By adopting the above technical solution, after the conductive end is inserted into the plug-in hole of the spring sheet, the insertion portion and the fixed section further form a limit, blocking the path of the conductive end to exit the plug-in hole, making the limit between the conductive part and the spring sheet more secure, and the two are installed more stably in the shell.

[0016] Optionally, the insertion portion has a guiding slope, the guiding slope is opposite to the wire insertion port, and the elastic section is opposite to the wire insertion port.

[0017] By adopting the above technical solution, after the wire is inserted into the wire socket, it can move along the guiding slope toward the elastic section, thereby driving the elastic section to separate from the conductive end, and the wire core of the motor can be inserted between the conductive end and the elastic section; when the wire is completely inserted, the elastic section re-contacts the wire core surface of the wire, thereby pressing the wire against the conductive section, so that the wire can be installed more stably in the housing.

[0018] Optionally, an insertion opening is provided in the wire insertion opening at an end edge close to the elastic section, and the end of the insertion portion is inserted into the insertion opening.

[0019] By adopting the above technical solution, during the process of inserting the wire into the wire socket, the end of the wire may abut against the end of the insertion part and cannot be inserted further. By clamping the end of the insertion part into the insertion port, the end of the insertion part is not easy to affect the insertion process of the wire, making the insertion process of the wire smoother.

[0020] Optionally, a fixing column is provided in the shell, and a connecting portion between the elastic section and the fixing section is bent to form a fixing ring, and the fixing ring is sleeved on the fixing column.

[0021] By adopting the above technical solution, the spring piece is installed in the housing after being matched with the conductive member, and the spring piece is fixed by the fixing column, which further makes the spring piece more firmly installed in the housing.

[0022] Optionally, the shell is provided with a handle positioning hole penetrating inside and outside, a handle is slidably installed in the handle positioning hole, and the handle abuts against the elastic section.

[0023] Optionally, a deformation cavity for elastic deformation of the elastic segment is formed between the elastic segment and the fixed segment; the fixed segment is provided with a sliding through hole for deformation and sliding of the elastic segment, and the sliding through hole is connected to the plug through hole.

[0024] By adopting the above technical solution, due to the existence of the deformation cavity and the sliding through hole, the deformation range of the elastic section is larger, and the wiring terminal can be inserted into a wire with a larger diameter, which is more practical.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. A terminal block, wherein a plug-in through hole for plugging in a conductive end is provided in a fixed section, and a limiting groove for engaging with the bent portion is formed by bending at the end of the fixed section, so that the conductive member and the spring sheet are mutually limited, and the spring sheet and the conductive member are installed together into the housing in the above-mentioned assembly method, and the spring sheet is not easy to pop out of the housing due to its elasticity;

[0027] 2. By providing a limiting bend at the end of the conductive end, the elastic section is not easy to slide out from the end of the conductive end due to the limiting of the limiting bend after elastically contacting the conductive end;

[0028] 3. By arranging an insertion portion at the end of the limiting bend, the insertion portion is stuck in the insertion port, and the insertion portion can guide the wire to slide toward the elastic section and separate the elastic section from the conductive end; and the end of the insertion portion is not easy to affect the process of inserting the wire into the shell, so that the wire can be plugged into the shell more smoothly.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] An embodiment of the present application discloses a wiring terminal.

[0036] Reference Figure 1 and Figure 2 The terminal block includes a shell 1, a conductive member 2 installed in the shell 1, a spring 3 installed in the shell 1 and elastically abutting against the conductive member 2, and a handle 4 installed on the shell 1. The shell 1 has an inner cavity 11 for installing the conductive member 2 and the spring 3, and the shell 1 is provided with two plug ports 12 for inserting and installing power lines that penetrate the inner cavity 11. After the two wires are inserted into the plug ports 12, they abut against the conductive member 2, and the conductive member 2 is used to conduct the two wires. The spring 3 is used to press the wires against the conductive member 2 so that the wires are not easily detached from the terminal block. The handle 4 cooperates with the spring 3 to drive the spring 3 to deform so that the wires can be removed from the terminal block.

[0037] Reference Figure 2 and Figure 3 The cross section of the conductive member 2 is C-shaped, and includes a mounting end 21 and a conductive end 22. The mounting end 21 is a long thin sheet, and the inner cavity 11 has a mounting groove 13, and the mounting section is fixed in the mounting groove 13. The conductive end 22 is a long thin sheet, and the number of the conductive ends 22 is two, corresponding to the number of the plug-in ports 12. The two conductive ends 22 are respectively connected to the two end portions of the mounting end 21 in one piece, and the ends of the conductive ends 22 are close to the connection between the plug-in port 12 and the inner cavity 11. When the wire is inserted into the plug-in port 12, the wire can abut against the conductive end 22.

[0038] Reference Figure 2 and Figure 3 The spring piece 3 includes an elastic section 31 and a fixed section 32 connected to the elastic section 31. The connection between the fixed section 32 and the elastic section 31 is bent to form a fixed ring 33. The housing 1 is provided with a fixed column 14 in the inner cavity 11. The fixed ring 33 is sleeved on the fixed column 14 so that the spring piece 3 can be fixed in the inner cavity 11. The fixed section 32 is a square strip-shaped thin sheet. Due to the bending of the fixed ring 33, the end of the elastic section 31 is close to the end of the fixed section 32, and the elastic section 31 is elastic, and the elastic section 31 always has a tendency to move away from the fixed section 32 and return to a natural state.

[0039] Reference Figure 2 and Figure 3When assembling the terminal block, the conductive member 2 and the spring 3 need to be assembled first, and then the two are installed together in the inner cavity 11, and there is an assembly structure between the conductive member 2 and the spring 3. The fixed section 32 is provided with a plug-in through hole 321, and the conductive end 22 is vertically inserted into the plug-in through hole 321. The side walls of the conductive end 22 are provided with a bending portion 23, and the bending portion 23 is perpendicular to the conductive end 22. The end of the fixed section 32 is bent to form a limiting groove 34, and the cross-section of the limiting groove 34 is C-shaped. The bending portion 23 is snap-fitted into the limiting groove 34.

[0040] Reference Figure 3 In this embodiment, there are two bending portions 23, which are symmetrically arranged on the side walls of the conductive end 22, and the limiting groove 34 is arranged along the entire width direction of the fixed section 32, so that the two bending portions 23 can be snapped into the limiting groove 34. The limiting groove 34 can also be in the form of segments, the limiting groove 34 is divided into two sections, and corresponds to the bending portions 23 one by one, so that the two bending portions 23 can be snapped into the two limiting grooves 34 one by one.

[0041] Reference Figure 2 and Figure 3 , the angle between the bent portion 23 and the conductive end 22 is greater than or equal to 90°, and the angle between the direction in which the bent portion 23 is inserted into the limiting groove 34 and the direction in which the conductive end 22 is inserted into the plug-in through hole 321 is greater than or equal to 90°, so that after the conductive member 2 and the spring sheet 3 are assembled, the bent portion 23 and the conductive end 22 are mutually limited. Due to the cooperation between the bent portion 23 and the limiting groove 34, the conductive end 22 is not easy to withdraw from the plug-in through hole 321 along the length direction. Due to the cooperation between the conductive end 22 and the plug-in through hole 321, the bent portion 23 is not easy to slide out of the limiting groove 34 along the width direction of the fixed section 32. Through the above-mentioned assembly structure, the conductive member 2 and the spring sheet 3 are well connected and not easy to separate during the process of being installed together into the inner cavity 11. And when the two are fixed in the inner cavity 11, the spring sheet 3 is not easy to pop out of the inner cavity 11 due to its own elastic force.

[0042] Reference Figure 2 and Figure 3 When the conductive member 2 and the spring sheet 3 are assembled in the inner cavity 11, the end of the elastic section 31 of the spring sheet 3 elastically abuts against the conductive end 22. At this time, the elastic section 31 is in a state of compression deformation. The end of the elastic section 31 always exerts deformation pressure on the conductive end 22, and the end of the elastic section 31 always has a tendency to slide out from the conductive end 22. In order to prevent the end of the elastic section 31 from sliding out from the conductive end 22, the end of the conductive end 22 is integrally connected to a limited position bend 24. The cross section of the limited position bend 24 is an arc shape and is bent toward the direction close to the elastic section 31. A limited position groove 25 is formed at the connection between the limited position bend 24 and the conductive end 22, and the end of the elastic section 31 elastically abuts against the limited position groove 25.

[0043] Reference Figure 2 and Figure 3 The conductive end 22 and the elastic section 31 are both located at the connection between the wire insertion port 12 and the inner cavity 11, and are directly opposite to the wire insertion port 12. When the wire is inserted into the wire insertion port 12, the end of the wire abuts against the elastic section 31 and drives the elastic section 31 to deform in the direction of increasing deformation pressure. At this time, the wire is located between the conductive end 22 and the end of the elastic section 31. Under the action of the deformation pressure, the elastic section 31 presses the wire against the conductive end 22, and the wire cannot be pulled out of the wire insertion port 12.

[0044] Reference Figure 1 and Figure 4 When the wire needs to be removed from the terminal, the spring piece 3 is opened by the handle 4. The housing 1 is provided with a handle positioning hole 15 that runs through the inside and outside. The handle 4 is slidably installed in the handle positioning hole 15, and one end of the handle 4 abuts against the elastic section 31. When the handle 4 is pressed, the elastic section 31 is deformed in the direction of increasing deformation pressure. At this time, the end of the elastic section 31 is separated from the wire, and the wire can be pulled out from the plug port 12.

[0045] Reference Figure 3 and Figure 4 In order to prevent the fixed section 32 from interfering with the elastic section 31 when the elastic section 31 moves in the direction of increasing deformation pressure, the fixed section 32 is provided with a sliding through hole 322 along the length direction, the sliding through hole 322 is connected with the plug through hole 321, and a deformation cavity 35 is provided between the elastic section 31 and the fixed section 32. When the elastic section 31 is deformed, the elastic section 31 can slide in the sliding through hole 322.

[0046] Reference Figure 2 and Figure 3 The end of the limiting bend 24 away from the conductive end 22 is integrally connected with an insertion portion 26. The insertion portion 26 bends in a direction away from the elastic section 31 and forms an angle with the conductive end 22, so that it is further limited with the fixed section 32, and the conductive end 22 is not easy to fall out of the plug-in through hole 321. The insertion portion 26 has a guiding slope 261, and the guiding slope 261 is directly opposite to the plug-in port 12. When the wire is inserted into the plug-in port 12, the wire can slide along the guiding slope 261 to the abutment between the conductive end 22 and the elastic section 31. In order to prevent the end of the insertion portion 26 from obstructing the wire during the insertion of the wire into the plug-in port 12, an insertion port 16 is provided at the edge of the connection between the plug-in port 12 and the inner cavity 11, and the insertion portion 26 is inserted into the insertion port 16.

[0047] Reference Figure 1 The side wall of the housing 1 is also provided with a cover plate 5, which covers the inner cavity 11, so that the conductive member 2 and the spring 3 are not easy to escape from the inner cavity 11 after being installed in the inner cavity 11.

[0048] Combination Figures 1 to 3The implementation principle of a terminal block in an embodiment of the present application is as follows: an assembly structure is provided between the conductive member 2 and the spring sheet 3, the conductive end 22 is inserted into the plug-in through hole 321, the bent portion 23 is clamped in the limiting groove 34, and the elastic section 31 abuts against the conductive end 22; after the bent portion 23 is clamped into the limiting groove 34, the conductive end 22 is restricted from withdrawing from the plug-in through hole 321, and after the elastic section 31 abuts against the conductive end 22, the bent portion 23 is pressed tightly into the limiting portion, further making the limiting of the spring sheet 3 and the conductive member 2 more stable.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
