For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] See also Figures 1 to 4The present invention provides a novel quick crimping device for terminal blocks, comprising a detachable base 1, wherein a lithium battery is arranged inside the base 1, for providing energy for the operation of the device and for electrically connecting with various components on the device. A hand-held handle 2 is arranged on the base 1, that is, the base 1 can be installed with the bottom of the hand-held handle 2 by snapping. A crimping switch 3 is arranged at one end of the hand-held handle 2 for starting the working principle, and a control compartment 4 is arranged at the top of the hand-held handle 2, and the control compartment 4 can be an internally arranged single-chip embedded control system to provide an operating environment for the entire device. A hydraulic press 5 is arranged on the control compartment 4, and one end of the hydraulic press 5 is movably connected to a crimping platform 6, and a plurality of crimping blocks are slidably arranged on the crimping platform 6, and a crimping groove 7 is arranged between every two crimping blocks, and a plurality of crimping grooves 7 are formed mutually by a plurality of crimping blocks, thereby realizing the crimping work of a plurality of terminal blocks during operation. Its working principle is that after the hydraulic press 5 is operated, the hydraulic push rod 12 thereon pushes the multiple crimping blocks to move, and finally the crimping grooves 7 between every two crimping blocks are squeezed against each other, thereby achieving the crimping effect of the terminal in each crimping groove 7. Through the control of the hydraulic press 5, the crimping force can be set in a targeted manner, so that each terminal can be crimped evenly and with stable quality.

[0030] Specific embodiments, such as Figure 1 As shown, at least four crimping blocks are arranged on the crimping platform 6, which are arranged as a first active crimping block 8, a second follower crimping block 9, a third follower crimping block 10 and a fourth fixed crimping block 11. That is, through the mutual squeezing action of the four crimping blocks, a group of crimping areas is formed between every two crimping blocks, and a total of three groups of terminal crimping effects are achieved, which effectively improves the work efficiency. The setting of the pressure groove 7 is as follows Figure 1 or Figure 2 As shown, the first active pressure block 8 and the fourth fixed pressure block 11 are only provided with the pressure groove 7 at one end, while the second follower pressure block 9 and the third follower pressure block 10 are provided with the pressure groove 7 at both ends.

[0031] The position of each crimping block on the crimping platform 6 is set as follows: the fourth fixed pressure block 11 is located at the front end of the crimping platform 6 and is fixedly installed with the crimping platform 6, so as to provide a stable crimping basis for the first three crimping blocks. Therefore, the crimping platform 6 can be made of metal material to ensure the strength and stability of the crimping. The first active pressure block 8 is located at the front end of the hydraulic press 5, which is used to provide the source driving force. The second follower pressure block 9 and the third follower pressure block 10 are both located between the fourth fixed pressure block 11 and the first active pressure block 8. During movement, after the first active pressure block 8 is driven by the hydraulic press 5, the first active pressure block 8 slides forward on the crimping platform 6, and then gradually pushes the second follower pressure block 9 and the third follower pressure block 10 in turn, and when continuing to move forward, it pushes to the fourth fixed pressure block 11 and stops, realizing the entire crimping movement principle.

[0032] Specific movement principles such as Figure 4 As shown, the hydraulic press 5 is provided with a hydraulic push rod 12, one end of which is connected to a linkage rod 13. When the hydraulic press 5 is started, the hydraulic push rod 12 drives the linkage rod 13 to extend or retract together. Since a cavity 14 is provided at the bottom of the crimping platform 6, the linkage rod 13 slides in the cavity 14. A connecting plate 15 is provided at the bottom of the first active pressing block 8 located in the cavity 14, and the connecting plate 15 is fixedly connected to one end of the linkage rod 13, that is, when the hydraulic push rod 12 moves, it drives the first active pressing block 8 to move together, thereby realizing the sliding movement effect of the first active pressing block 8 as a source of power on the crimping platform 6.

[0033] Continue as Figure 4 As shown, the bottom of the second follower pressure block 9 and the third follower pressure block 10 located in the cavity 14 are respectively provided with a second extension plate 16 and a third extension plate 17, and the second extension plate 16 and the third extension plate 17 respectively slide with the second follower pressure block 9 and the third follower pressure block 10 in the cavity 14. The second extension plate and the third extension plate 17 are used to provide a reaction force support effect of the elastic reset mechanism 18, so as to realize the movement position reset effect of the second follower pressure block 9 and the third follower pressure block 10 on the crimping platform 6. That is, the elastic reset mechanism 18 is provided between the connecting plate 15 and the second extension plate, between the second extension plate and the third extension plate 17, and between the third extension plate 17 and the side wall of the cavity 14.

[0034] In order to ensure the unimpeded movement of the linkage rod 13 in the cavity 14, the second extension piece, the third extension piece 17 and the elastic reset mechanism 18 are all arranged above the linkage rod 13, and the elastic reset mechanism 18 is set as a tension spring or a hydraulic connecting rod, which has an elastic structure. In use, when the hydraulic press 5 drives the hydraulic push rod 12 to retract, the linkage rod 13 drives the first active pressure block 8 to retract and reset, and the second follower pressure block 9 and the third follower pressure block 10 are also gradually slid and reset on the crimping platform 6 under the action of each other's elastic reset mechanism 18, so that the crimping groove 7 between every two crimping blocks is opened, and the crimped terminal can be taken out.

[0035] Furthermore, an electronic display screen 19 is provided at one end of the hydraulic press 5, and a parameter adjustment button 20 is provided at one end of the control chamber 4, and the electronic display screen 19 is located above the parameter adjustment button 20. By equipping the device with an electronic display screen 19, the operator can monitor the degree and progress of crimping in real time. Through these feedback information, the operator can intuitively confirm the crimping quality and accuracy of each terminal, reduce human errors, and improve work accuracy. The parameter adjustment button 20 set at the tail of the device allows the operator to input and adjust the required crimping force through the parameter adjustment button 20, and the control chamber 4 adjusts the working state of the hydraulic press 5 according to this set pressure to improve the crimping accuracy of the parallel wiring terminal. Its set value can also be adjusted individually according to the material and structural requirements of different terminals, which improves flexibility.

[0036] Furthermore, a support bracket 21 is detachably mounted on the lower end of the crimping platform 6, and a sliding seat 22 is provided on the top of the support bracket 21. The sliding seat 22 is slidably mounted on the bottom of the crimping platform 6. By providing the support bracket 21, the device can be flexibly applied in different environments, which is conducive to enhancing user experience. The design of the detachable support bracket 21 also improves the portability and stability of the device, allowing operators to perform crimping operations more conveniently and accurately on the ground, adapting to various working conditions.

[0037] Furthermore, an observation plane is provided on one end side wall of the crimping platform 6, and a crimping scale 23 is provided on the observation plane, so that the operator can monitor the crimping degree in real time during crimping, provide feedback information to the operator, and effectively ensure the crimping quality.

[0038] Working principle: When the crimping work starts, press the crimping switch 3, the hydraulic press 5 starts, and the hydraulic push rod 12 moves in the cavity 14. Since the first active pressure block 8 is the source power on the crimping platform 6, when the hydraulic press 5 pushes the first active pressure block 8, the first active pressure block 8 slides forward on the crimping platform 6, and then gradually pushes the second follower pressure block 9 and the third follower pressure block 10 in turn. When it continues to move forward, it stops at the fourth fixed pressure block 11, so as to achieve the full crimping movement effect. During the crimping process, the control chamber 4 continuously obtains the real-time pressure data of the hydraulic press 5. If the pressure of the hydraulic press 5 reaches the set value, the control chamber 4 will immediately send a signal to the hydraulic press 5 to stop the operation of the hydraulic press 5, thereby avoiding the occurrence of overpressure and ensuring the crimping quality and consistency of each terminal. Furthermore, the control chamber 4 can be set with overpressure protection and emergency stop functions to prevent excessive pressure in unexpected situations and protect the safety of equipment and operators. This precise force control ensures the uniformity and stability of crimping, effectively avoiding wiring quality problems caused by uneven force, thereby enhancing the firmness of the connection.

[0039] In summary, the novel quick crimping device for terminal blocks provided by the present invention solves the drawback that the traditional crimping equipment can only crimp a single terminal block. By setting four crimping blocks, the simultaneous crimping operation of at least three groups of terminals is realized, and the device has a precise crimping force control function, which ensures that the crimping quality of each terminal meets the standard and improves work efficiency. In the case where multiple terminals need to be processed at the same time, the operation process is fast and time-saving, which meets the needs of rapid maintenance. By setting a hydraulic press 5 to crimp the terminals, the accuracy of the crimping force control is improved, so that each terminal can be crimped evenly, avoiding the traditional method of relying on manual adjustment by the operator, ensuring the stability of the crimping quality, and improving the reliability of the electrical connection. The good and stable crimping effect not only reduces the probability of equipment failure in the later stage, but also reduces the subsequent repair and maintenance costs, which is conducive to improving the overall economic benefits of power operation and maintenance. By setting an electronic display screen 19, the function of setting real-time monitoring is improved, so that the equipment can timely provide feedback on the crimping progress or quality, giving the operator a standard for judgment, and improving the safety of operation.
