Description

Technical Field

[0001] This utility model relates to the technical field of terminal crimping equipment, and specifically to a terminal crimping device. Background Technology

[0002] A terminal block crimping machine is a specialized piece of equipment used for wire processing. It is mainly used to quickly and accurately crimp terminals (connectors) to the ends of wires, enabling reliable connections between wires and electrical equipment, circuit boards, or other conductors.

[0003] For example, CN118748343A discloses a terminal crimping device for connectors, which includes a winding assembly, a conveying assembly, a positioning assembly, an operating table, a mounting frame, and a support plate and a base plate disposed on the operating table. The support plate is elastically slidably disposed above the base plate, and a cutter plate is disposed on the base plate, penetrating the support plate. The cutter plate is used to cut the terminal components from the strip during the stamping process. The winding assembly is disposed on the mounting frame, and the conveying assembly and the positioning assembly are disposed on the support plate. A drive mechanism is disposed on the mounting frame, and the output end of the drive mechanism is connected to a lifting platform. An adaptive crimping assembly is disposed at the lower end of the lifting platform.

[0004] As the market for terminal blocks develops, some terminal blocks will have connector tabs attached to their ends. During the crimping process, the connector tabs need to be bent to facilitate connection with the terminal block. However, existing crimping equipment can only assemble conventional terminal blocks and cannot crimp terminal blocks with connector tabs. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes a crimping device for wiring terminals.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] A crimping device for terminal blocks includes a crimping base with a conveying channel for conveying terminal blocks. The terminal blocks include connecting pieces, ends spaced apart on the connecting pieces, and plug pieces horizontally connected to the sides of the ends. A bending structure and a crimping structure are sequentially arranged along the conveying direction of the terminal blocks.

[0008] The bending structure includes a bending block that is vertically and retractably disposed below the plug-in piece, wherein the plug-in piece bends vertically as the bending block rises.

[0009] The crimping structure includes a lower blade holder for placing a wire and cutting the end, and a crimping head movably disposed above the end, wherein the end retracts inward from both sides as the crimping head descends, and the crimping head drives the lower blade holder to descend and cut off the end.

[0010] Preferably, the crimping seat is provided with a connecting rod structure, and the connecting rod structure has a first actuating end that connects to the bending block and a second actuating end that connects to the crimping head, so that the bending structure and the crimping structure move synchronously. Through the above improvements, the connecting structure is driven by the driving unit to move, so that the first actuating end and the second actuating end drive the bending block and the crimping head to move synchronously, thereby ensuring the smoothness of the entire crimping process and further improving the crimping efficiency.

[0011] Preferably, the crimping connector includes a sliding block and a pressure plate assembly disposed on the sliding block. The pressure plate assembly includes spaced-apart extrusion plates, each extrusion plate having an extrusion groove for inserting an end piece. The extrusion groove tends to converge along the end piece insertion direction. With the above improvements, when the end piece is crimped, as the sliding block drives the pressure plate assembly to descend, the end piece will be inserted into the extrusion groove. As the extrusion groove gradually converges, the end piece is drawn in from both sides and fixed and guided, thus realizing the crimping process.

[0012] Preferably, the pressing plate assembly further includes a straightening plate disposed between the pressing plates. The straightening plate forms a guide arc surface. The insertion plate slides along the guide arc surface as the pressing head descends, forcing the insertion plate to be vertically disposed on the side of the connecting end. Through the above improvement, when the insertion plate is bent by the bending block, the insertion plate will bend upward. However, due to the elasticity of the metal, the insertion plate cannot be guaranteed to be completely vertical. By utilizing the further action of the straightening plate on the insertion plate, the insertion plate is made to be vertically disposed on the side of the connecting end, thereby improving the bending effect of the insertion plate.

[0013] Preferably, the crimp connector is provided with a pressure holding block, and when the bending block bends the plug piece upwards, the pressure holding block abuts against the end and is arranged adjacent to the bending block. Through the above improvements, during the bending process of the plug piece, the pressure holding block will abut against the end to ensure stability during the bending process.

[0014] Preferably, the lower cutter holder includes a cutting block slidably disposed on the pressing seat and a support plate fixedly disposed on the pressing seat. The end is disposed on the support plate, and the cutting block forms a cutting groove for the connecting piece to be inserted. With the above improvement, the connecting piece is inserted into the cutting groove, and the end is disposed on the support plate. When pressing is performed, the pressing plate assembly presses the end against the support plate, and the pressing head squeezes the cutting block down, causing the end to detach from the connecting plate, thereby achieving the cutting of the end.

[0015] Preferably, the crimping seat is provided with a first elastic element, one end of which abuts against the cutting block and the other end of which abuts against the crimping seat. Through the above improvements, the cutting block can be automatically reset by using the first elastic element, which makes it easier for users to place wires.

[0016] Preferably, the crimping connector is provided with a pressing block, which presses the cutting block and forces it to descend to cut off the end. Through the above improvement, during the crimping process, as the crimping connector descends, the pressing block on the crimping connector will abut against the cutting block and force it to descend to achieve the cutting of the end.

[0017] Preferably, the crimp connector is provided with a limiting seat, the pressure holding block is slidably disposed within the limiting seat, and a second elastic element is provided within the limiting seat. One end of the second elastic element abuts against the limiting seat, and the other end abuts against the pressure holding block. Through the above improvements, the pressure holding block is flexibly disposed, avoiding damage to the end.

[0018] Preferably, the crimping seat has a guide groove, and the bending block and the crimping head are slidably disposed in the guide groove. Through the above improvements, the stability of the bending block and the crimping head during movement is enhanced.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] The crimping unit features a conveying channel for transporting terminal blocks, and sequentially includes a bending structure and a crimping structure along the terminal block conveying direction. The bending structure includes a bending block that is vertically adjustable below the connector, and the crimping structure includes a lower cutter for placing the wire and cutting the end, and a crimping head movably positioned above the end. During the crimping process, the terminal block moves intermittently along the conveying channel. It first moves above the bending block, which then bends the connector upwards. The terminal then moves below the crimping structure, and the end retracts inwards from both sides as the crimping head descends to connect the wire. The crimping head then drives the lower cutter to descend and cut the end, achieving a rapid connection between the end and the wire. The bending structure can be stopped during use, making the crimping equipment compatible with conventional terminal blocks. Compared to conventional crimping equipment, this allows for compatibility with different types of terminal blocks, improving the user experience. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0030] like Figure 1-6 As shown, a crimping device for a terminal block 3 includes a crimping base 1, a conveying channel 2 for conveying the terminal block 3 is provided on the crimping base 1, the terminal block 3 includes a connecting piece 4, an end piece 5 spaced apart on the connecting piece 4, and a plug piece 6 horizontally connected to the side of the end piece 5, and a bending structure 7 and a crimping structure 8 are sequentially arranged along the conveying direction of the terminal block 3.

[0031] Specifically, the bending structure 7 includes a bending block 1.1 that is vertically mounted below the plug-in piece 6. When the terminal 3 moves above the bending block 1.1, the plug-in piece 6 rises and bends vertically with the bending block 1.1.

[0032] Furthermore, the crimping structure 8 includes a lower blade holder 1.2 for placing the wire and cutting the end 5, and a crimping connector 1.3 movably disposed above the end 5. When the terminal 3 moves below the crimping connector 1.3, the end 5 retracts inward from both sides as the crimping connector 1.3 descends to connect the wire, and the crimping connector 1.3 drives the lower blade holder 1.2 to descend and cut off the end 5.

[0033] During the entire crimping process, the terminal block 3 moves intermittently along the conveying channel 2. The terminal block 3 first moves above the bending block 1.1, and the bending block 1.1 rises to bend the connector 6 of the terminal block 3 upwards. Then it moves below the crimping structure 8, and the end 5 retracts inward from both sides as the crimping connector 1.3 descends to connect the wire. The crimping connector 1.3 drives the lower cutter 1.2 to descend and cut off the end 5, realizing a quick connection between the end 5 and the wire. During use, the operation of the bending structure 7 can be stopped, making the crimping equipment compatible with conventional terminal blocks 3. Therefore, compared with conventional crimping equipment, it can be compatible with different types of terminal blocks 3, thereby improving the user experience.

[0034] like Figure 1 , Figure 3 As shown, the crimping seat 1 is also provided with a material feeding structure 10. The material feeding structure 10 includes a material feeding block 6.1 provided on the crimping seat 1 and a material feeding rod 6.2 transferred on the material feeding block 6.1. The material feeding block 6.1 moves up and down with the crimping head 1.3.

[0035] Furthermore, the crimp connector 1.3 is provided with a drive block 5.1, the drive block 5.1 is provided with a drive wheel 5.2, and the feeding block 6.1 is provided with a drive groove 5.3 for the drive wheel 5.2 to be inserted into. The drive groove 5.3 is inclined. As the drive wheel 5.2 slides in the drive groove 5.3, the drive block 5.1 tilts and slides, so that the feeding rod 6.2 can move the terminal 3 in the conveying channel 2.

[0036] Preferably, the feeding block 6.1 is provided with a tension spring, which is connected to the feeding rod 6.2 so that the feeding rod 6.2 always has a tendency to rotate toward the feeding direction of the terminal 3.

[0037] like Figure 1-6 As shown, as a further explanation of the linkage structure 9, the crimping seat 1 is provided with the linkage structure 9, and the linkage structure 9 has a first actuating end 2.1 that connects to the bending block 1.1 and a second actuating end 2.2 that connects to the crimping head 1.3, so that the bending structure 7 and the crimping structure 8 can move synchronously.

[0038] Specifically, the linkage structure 9 includes a hinged first connecting rod 7.1 and a second connecting rod 7.2. The first connecting rod 7.1 connects to the crimping head 1.3, and the second connecting rod 7.2 connects to the bending block 1.1. The connecting structure is driven by a drive unit to move, so that the first connecting rod 7.1 and the second connecting rod 7.2 drive the bending block 1.1 and the crimping head 1.3 to move synchronously, thereby ensuring the smoothness of the entire crimping process and further improving the crimping efficiency.

[0039] Additionally, the second connecting rod 7.2 can be detached to allow the crimp connector 1.3 to operate independently, thus making the crimping equipment compatible with conventional terminal blocks 3.

[0040] Preferably, the crimping seat 1 is provided with a guide groove 4.8, and the bending block 1.1 and the crimping head 1.3 are slidably disposed in the guide groove 4.8, which improves the stability of the bending block 1.1 and the crimping head 1.3 during the movement process.

[0041] like Figure 3 , Figure 4 As shown, as a further explanation of the implementation of the bending structure 7, a pressure holding block 4.1 is provided on the crimping joint 1.3, and when the bending block 1.1 bends the insert piece 6 upward, the pressure holding block 4.1 abuts against the end 5 and is arranged adjacent to the bending block 1.1 to ensure stability during the bending process and prevent the end 5 from shifting during the bending process.

[0042] Specifically, a limiting seat 4.6 is provided on the crimp connector 1.3, and a pressure holding block 4.1 is slidably disposed within the limiting seat 4.6. A second elastic element 4.7 is provided within the limiting seat 4.6. One end of the second elastic element 4.7 abuts against the limiting seat 4.6, and the other end abuts against the pressure holding block 4.1, so that the pressure holding block 4.1 is flexibly disposed to avoid damage to the end 5.

[0043] like Figure 1-6 As shown, in a further explanation of the embodiment of the crimping structure 8, the crimping joint 1.3 includes a sliding block 3.1 and a pressing plate group 3.2 disposed on the sliding block 3.1. The pressing plate group 3.2 includes extrusion plates 3.3 disposed at intervals. The extrusion plates 3.3 are formed with extrusion grooves 3.4 for inserting the end head 5, and the extrusion grooves 3.4 tend to converge along the insertion direction of the end head 5.

[0044] When the end 5 is crimped, as the sliding block 3.1 drives the pressing group 3.2 to descend, the end 5 will be placed into the extrusion groove 3.4. As the extrusion groove 3.4 gradually closes, the end 5 is gathered from both sides and fixed and guided, thus realizing the crimping process.

[0045] Furthermore, the tablet assembly 3.2 also includes a straightening plate 3.5 disposed between the extrusion tablets 3.3. The straightening plate 3.5 forms a guide arc surface 3.6 on the straightening plate 3.6. The insertion piece 6 slides along the guide arc surface 3.6 as the pressing head 1.3 descends, and forces the insertion piece 6 to be vertically disposed on the side of the connecting end 5.

[0046] After the connector 6 is bent by the bending block 1.1, the connector 6 will bend upward. However, due to the elasticity of the metal, the connector 6 cannot be guaranteed to be completely vertical. The straightening piece 3.5 further acts on the connector 6 to make the connector 6 vertically set on the side of the connecting end 5, so as to improve the bending effect of the connector 6.

[0047] Additionally, the lower cutter holder 1.2 includes a cutting block 4.2 slidably mounted on the crimping seat 1 and a support plate 4.3 fixedly mounted on the crimping seat 1. The end 5 is mounted on the support plate 4.3, and the cutting block 4.2 forms a cutting groove 4.9 for the connecting piece 4 to be inserted. During the crimping process, the connecting piece 4 is inserted into the cutting groove, and the end 5 is mounted on the support plate 4.3. When crimping is performed, the pressing plate assembly 3.2 presses the end 5 against the support plate 4.3, and the crimping head 1.3 squeezes the cutting block 4.2 down, causing the end 5 to detach from the connecting piece 4, thereby achieving the cutting of the end 5.

[0048] The crimping connector 1.3 is provided with a pressing block 4.5. During the crimping process, as the crimping connector 1.3 descends, the pressing block 4.5 on the crimping connector 1.3 will abut against the cutting block 4.2 and force it to descend, so as to cut the end 5.

[0049] Preferably, the crimping seat 1 is provided with a first elastic element 4.4. One end of the first elastic element 4.4 abuts against the cutting block 4.2, and the other end abuts against the crimping seat 1. The first elastic element 4.4 is used to realize the automatic reset of the cutting block 4.2, which makes it easier for users to place wires.

[0050] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
