Description

Technical Field

[0001] This utility model relates to the field of terminal assembly technology, and in particular to a terminal assembly fixture with a crimping and limiting mechanism. Background Technology

[0002] Terminal blocks are components used to achieve electrical connections and mechanical fixation between wires, cables, or electronic components, commonly found in wire harnesses, electrical equipment, and automation equipment. Crimping equipment is often used during terminal assembly. Existing crimping fixtures are mostly single rigid limiters or simple spring buffers, which cannot effectively disperse impact forces and easily lead to terminal deformation. Therefore, there is an urgent need to develop a terminal assembly fixture with a crimping limiting mechanism that utilizes a triple buffer of springs, micro-hydraulic dampers, and polyurethane elastic buffer plates, combined with a rigid limit frame for hard limiting. This fixture can efficiently absorb crimping impact forces and prevent terminal deformation, overcoming the shortcomings of current practical applications and meeting current needs. Utility Model Content

[0003] The purpose of this invention is to provide a terminal assembly fixture with a crimping and limiting mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A terminal assembly fixture with a crimping limiting mechanism includes a bracket, a lower mold, a hydraulic cylinder, an upper mold, and a limiting buffer mechanism. The lower mold is fixed to the bracket, and the upper mold is located above the lower mold and cooperates with it. The hydraulic cylinder is fixed to the upper end of the bracket, and the telescopic end of the hydraulic cylinder is fixed to the upper mold. Pressure rods are fixed to the front and rear sides of the upper mold. Two limiting buffer mechanisms are installed on the bracket, with each limiting buffer mechanism located directly below the two pressure rods. Each limiting buffer mechanism includes a rigid limiting frame, a buffer rod, a spring, and a miniature hydraulic damper. The system comprises an extension plate, a pressure dispersion rod, and an elastic buffer plate. The rigid limiting frame is fixed to the bracket. The buffer rod passes through the rigid limiting frame and slides in contact with it, with the buffer rod facing the pressure rod. A spring is installed on the outer side of the lower half of the buffer rod. The upper end of the spring is fixed to the rigid limiting frame, and the lower end of the spring is fixed to the buffer rod. A miniature hydraulic damper is fixed to the bottom of the buffer rod on the bracket. Multiple extension plates are fixed to the outer side of the upper end of the buffer rod. A pressure dispersion rod is fixed below each extension plate, facing the elastic buffer plate, which is fixed to the bracket.

[0006] Preferably, the elastic buffer plate is made of polyurethane material.

[0007] Preferably, the upper mold has two guide rods that pass through the support, and the guide rods slide in contact with the support.

[0008] Preferably, a hydraulic station is installed on the bracket, and the hydraulic cylinder is connected to the hydraulic station through an oil supply pipeline. The hydraulic station is used to supply hydraulic oil to the hydraulic cylinder to drive its operation.

[0009] The beneficial effects of this utility model are as follows: When using this terminal assembly fixture with a crimping and limiting mechanism, the terminal to be crimped is placed on the lower mold, and then the upper mold is moved downwards by a hydraulic cylinder. The upper mold presses down onto the lower mold to crimp the terminal. Simultaneously, the upper mold moves the pressure rod downwards. During the downward movement of the pressure rod, it first presses against the buffer rod, which causes the spring to deform for buffering. As the pressure rod gradually moves downwards, it presses against the micro hydraulic damper, which absorbs the impact. At the same time, the buffer rod moves the extension plate and pressure dispersion rod downwards, which disperse the pressure onto the elastic buffer plate. The elastic buffer plate deforms for further buffering. Finally, the upper end of the buffer rod presses against the hard limiting frame to achieve hard limiting. In summary, this utility model, through triple buffering of springs, micro hydraulic dampers, and polyurethane elastic buffer plates, combined with hard limiting of the hard limiting frame, can efficiently absorb the crimping impact force and prevent terminal deformation.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] See Figures 1-4 In this embodiment of the present invention, a terminal assembly fixture with a pressing and limiting mechanism includes a bracket 1, a lower mold 2, a hydraulic cylinder 3, an upper mold 4, and a limiting and buffering mechanism 5. The lower mold 2 is fixed to the bracket 1, and the upper mold 4 is located above the lower mold 2 and cooperates with it. The hydraulic cylinder 3 is fixed to the upper end of the bracket 1, and the telescopic end of the hydraulic cylinder 3 is fixed to the upper mold 4. Pressure rods 402 are fixed on the front and rear sides of the upper mold 4, respectively. The limiting and buffering mechanism 5 consists of two parts and is installed on the bracket 1. The limiting and buffering mechanism 5 is located directly below the two pressure rods 402. The limiting and buffering mechanism 5 includes: a rigid limiting frame 501, a buffer rod 502, a spring 503, a micro hydraulic damper 504, an extension plate 505, a pressure dispersing rod 506, and an elastic buffer plate 507. The rigid limiting frame 501 is fixed to the bracket 1. The buffer rod 502 passes through the rigid limiting frame 501 and slides in contact with it. The buffer rod 502 faces the pressure rods 402. A spring 503 is installed on the outer side of the lower half of the buffer rod 502. The upper end of the spring 503 is fixed to the rigid limiting frame 501, and the lower end of the spring 503 is fixed to the buffer rod 502. A miniature hydraulic damper 504 is fixed to the lower part of the buffer rod 502 on the bracket 1. Multiple extension plates 505 are fixed to the outer side of the upper end of the buffer rod 502. A pressure dispersion rod 506 is fixed to the lower part of each extension plate 505. The pressure dispersion rod 506 faces the elastic buffer plate 507. The elastic buffer plate 507 is fixed to the bracket 1. In use, the pressure rod 402 moves downward. During the process, the pressure is first applied to the buffer rod 502, which causes the spring 503 to deform for buffering. The pressure rod 402 gradually moves down and presses on the micro hydraulic damper 504, which buffers the impact. At the same time, the buffer rod 502 causes the extension plate 505 and the pressure dispersion rod 506 to move down. The pressure dispersion rod 506 disperses the pressure onto the elastic buffer plate 507, which deforms to buffer the impact. Finally, the upper end of the buffer rod 502 presses on the hard limit frame 501 to achieve hard limiting.

[0019] The elastic buffer plate 507 is made of polyurethane material, which gives it good elastic buffering performance.

[0020] Two guide rods 401 that pass through the bracket 1 are fixed on the upper mold 4. The guide rods 401 slide in contact with the bracket 1 and limit the upper mold 4 to move only up and down.

[0021] A hydraulic station 6 is installed on the bracket 1. The hydraulic cylinder 3 is connected to the hydraulic station 6 through an oil supply pipeline (not shown). The hydraulic station 6 is used to supply hydraulic oil to the hydraulic cylinder 3 to drive its operation.

[0022] Working principle: This terminal assembly fixture with a crimping and limiting mechanism is used by placing the terminal to be crimped onto the lower mold 2, and then driving the upper mold 4 to move down through the hydraulic cylinder 3. The upper mold 4 presses down onto the lower mold 2 to crimp the terminal. At the same time, the upper mold 4 drives the pressure rod 402 to move down. During the downward movement of the pressure rod 402, it first presses onto the buffer rod 502. The buffer rod 502 causes the spring 503 to deform for buffering. As the pressure rod 402 moves down, it presses onto the micro hydraulic damper 504. The micro hydraulic damper 504 buffers and absorbs the impact. At the same time, the buffer rod 502 drives the extension plate 505 and the pressure dispersion rod 506 to move down. The pressure dispersion rod 506 disperses the pressure onto the elastic buffer plate 507. The elastic buffer plate 507 deforms for buffering. Finally, the upper end of the buffer rod 502 presses onto the hard limiting frame 501 to achieve hard limiting.

[0023] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
