[0003] Traditional methods typically involve manually inserting the stripped core wire into the metal sleeve of the pre-insulated terminal, and then moving it to crimping pliers or a small crimping machine to complete the crimping. This method lacks axial positioning, and the metal sleeve can wobble left and right in the V-groove of the crimping pliers, making it very easy for the core wire to be inserted crookedly. After crimping, issues such as "eccentricity" or "flash" may occur, and the efficiency of this method needs to be improved.
[0004] Therefore, it is necessary to propose a pre-insulated terminal positioning and insertion mold to solve the above problems. Utility Model Content

[0026] Example 1: This utility model provides the following... Figures 1-5 The pre-insulated terminal positioning and insertion mold shown includes a base 1, a C-shaped frame 2 fixedly connected to the base 1, and the base 1 is installed on an operating table; the top of the base 1 is fixedly connected to the C-shaped frame 2, and the insertion and positioning of the multi-core wire harness and the pre-insulated terminal are completed at the C-shaped frame 2.
[0027] The upper surface of the bottom end of the C-shaped frame 2 is provided with a feeding channel 3. In actual use, a vibratory feeder and a vibratory guide rail are connected to the feeding channel 3. The pre-insulated terminals are automatically fed into the feeding channel 3 using the vibratory feeder and the vibratory guide rail. The vibratory feeder and the vibratory guide rail are common existing technologies and will not be described in detail here.
[0028] A push rod 4 is slidably installed inside the feeding channel 3. An electric cylinder 5 is fixedly connected to the base 1. The push rod 4 is fixedly connected to the telescopic end of the electric cylinder 5. The electric cylinder 5 drives the push rod 4 to move, thereby pushing the pre-insulated terminal to be fed.
[0029] A positioning component is provided at the end of the feeding channel 3 away from the push rod 4. The positioning component includes a fixed clamp 6 and a movable clamp 7. The fixed clamp 6 is fixedly connected to the C-shaped frame 2, and the movable clamp 7 is located above the fixed clamp 6. Both the fixed clamp 6 and the movable clamp 7 have arc-shaped cuts at their respective ends. When the fixed clamp 6 and the movable clamp 7 are close together, the pre-insulated terminal is fixed in the circular groove formed by the two arc-shaped cuts.
[0030] A slide block 12 is slidably mounted on the C-shaped frame 2, and a movable clamp 7 is fixedly connected to the bottom end of the slide block 12. The C-shaped frame 2 is equipped with a drive device that drives the slide block 12 to move up and down, including an electric push rod (not shown in the figure), which drives the movable clamp 7 to move up and down through the slide block 12.
[0031] Electric cylinder 5, drive equipment, etc. are all connected to the factory's power supply.
[0032] A clamping component is provided on the side of the positioning component facing away from the push rod 4. The clamping component includes a pressing mold 10 and a supporting mold 11. The supporting mold 11 is fixedly connected to the C-shaped frame 2, and the pressing mold 10 is located above the supporting mold 11.
[0033] A pneumatic gripper 8 is fixedly connected to the base 1, and a movable end 9 is provided on the pneumatic gripper 8. The pressure mold 10 is fixedly connected to the movable end 9.
[0034] In actual use, the pre-insulated terminals are automatically fed into the feeding channel 3 using a vibratory feeder and vibratory guide rail. Then, the telescopic end of the electric cylinder 5 is extended, driving the push rod 4 to move towards the pressing assembly, and the pre-insulated terminals move synchronously. When they move to the positioning assembly, the moving clamp 7 moves downward. The fixed clamp 6 and the moving clamp 7 cooperate to axially position the pre-insulated terminals, preventing them from sliding randomly and ensuring the accuracy of the connection with the multi-core wire harness. Then, the operator inserts the stripped multi-core wire harness into the pre-insulated terminals, and the pneumatic gripper 8 drives the pressing mold 10 to move downward. The pressing mold 10 cooperates with the support mold 11 to complete the pressing operation.
[0035] This utility model, by setting up push rod 4, positioning component, clamping component and other structures, can quickly axially position the pre-insulated terminal, avoid the pre-insulated terminal from sliding randomly, ensure the accuracy of docking with multi-core wire harness, and improve the utilization efficiency of the pre-insulated terminal positioning and plugging mold.
[0036] Example 2, the present invention provides as follows Figures 6-7 The pre-insulated terminal positioning and insertion mold shown takes into account that the existing pre-insulated terminal crimping contours of the customer are circular and square. In order to increase the flexibility of processing and production and realize the control of the crimping contour shape, adjustment components are provided at the ends of the pressing mold 10 and the support mold 11 that are close to each other. In the pressing mold 10, the adjustment components include a motor 13, a turntable 14, a rotating cavity 15 and a pressing groove 16. The rotating cavity 15 is opened on the pressing mold 10 and passes through the end of the pressing mold 10 near the support mold 11. The turntable 14 is located inside the rotating cavity 15. The motor 13 is fixedly connected to the outer wall of the pressing mold 10, and the turntable 14 is fixedly connected to the drive shaft of the motor 13.
[0037] In the support mold 11: the adjustment assembly includes a motor 13, a turntable 14, a rotating cavity 15 and a pressing groove 16. The rotating cavity 15 is opened on the support mold 11 and passes through the end of the support mold 11 near the pressing mold 10. The turntable 14 is located inside the rotating cavity 15. The motor 13 is fixedly connected to the outer wall of the support mold 11, and the turntable 14 is fixedly connected to the drive shaft of the motor 13.
[0038] The pressing groove 16 is formed on the outer ring of the turntable 14. There are multiple pressing grooves 16, and the shapes of the multiple pressing grooves 16 are different, including rectangular and semi-circular, or other shapes. Two semi-circular pressing grooves 16 cooperate to form a circular pressing profile; two rectangular pressing grooves 16 cooperate to form a square pressing profile.
[0039] In addition, the inner wall of the crimping groove 16 is provided with protruding teeth. During the crimping process, the protruding teeth squeeze out a recess on the pre-insulated terminal, which improves the mating strength.
[0040] To ensure the stability of the upper and lower turntables 14, the upper turntable 14 (corresponding to the pressure mold 10) has limit teeth 17 on both sides of the pressure groove 16. The limit teeth 17 are fixedly connected to the outer ring of the corresponding turntable 14. The lower turntable 14 (corresponding to the support mold 11) has limit grooves 18 on both sides of the pressure groove 16. The limit grooves 18 are opened on the outer ring of the corresponding turntable 14, and the limit teeth 17 and the corresponding limit grooves 18 are inserted and engaged.
[0041] During the crimping operation (taking a circular outline as an example): Start the motor 13, and the motor 13 drives the turntable 14 to rotate, causing the semi-circular crimping groove 16 on the upper turntable 14 to face downwards, and the semi-circular crimping groove 16 on the lower turntable 14 to face upwards.
[0042] The air gripper 8 drives the mold 10 to move downwards, and the two semi-circular pressing grooves 16 approach and squeeze, making the pressing outline circular. During this process, the limiting teeth 17 are inserted into the corresponding limiting grooves 18 to achieve the limiting effect. The two turntables 14 form a whole, improving the stability of the turntables 14 and preventing them from rotating randomly.
[0043] By setting adjustment components, the shape of the crimping profile can be flexibly switched and a limiting effect can be achieved, improving the stability of the turntable 14 and ensuring the quality of the crimping profile.
