[0002] A crystal head is a standardized telecommunications network interface that provides an interface for voice and data transmission.
[0003] The crimping of the RJ45 connector (the connector body) with the network cable is usually completed in two steps: the first step is to insert the network cable into the wire slot of the RJ45 connector body according to the wire sequence, and the second step is to use crimping pliers or a small crimping machine to pierce the wire insulation with the metal blade of the RJ45 connector body and bend and fix it in one go.
[0004] Because of the small size of the RJ45 connector and the high requirements for wire sequence, traditional crimping dies rely solely on simple baffles on both sides of the jaws for positioning. This causes the RJ45 connector to move back and forth during crimping, resulting in inconsistent contact depth between the cutting edge and the core wire, which affects efficiency.
[0005] Therefore, it is necessary to propose a crystal head forming mold to solve the above problems. Utility Model Content

[0028] Example 1: This utility model provides the following... Figures 1-6 The crystal head forming mold shown includes a base 1, which is installed on an operating table. A C-shaped frame 2 is fixedly connected to the top of the base 1, and the crystal head body 14 and the network cable are crimped and formed at the C-shaped frame 2.
[0029] The bottom of the C-shaped frame 2 is provided with a first guide plate 3 and a second guide plate 4. The first guide plate 3 and the second guide plate 4 are distributed in parallel and a sliding gap is formed between the first guide plate 3 and the second guide plate 4. In actual use, the spring contacts of the crystal head body 14 face downward and are located in the sliding gap. The two sides of the bottom of the crystal head body 14 are respectively attached to the first guide plate 3 and the second guide plate 4.
[0030] The first guide plate 3 is provided with a feeding groove 5 for feeding the crystal head body 14. The feeding groove 5 is adapted to the shape of the spring of the crystal head body 14, so that the spring can be inserted into the sliding gap through the feeding groove 5.
[0031] In actual use, a vibratory feeder and a vibratory guide rail are connected to the feeding trough at 5 points. Automatic feeding is achieved using the vibratory feeder and vibratory guide rail. The vibratory feeder and vibratory guide rail are common existing technologies and will not be described in detail here.
[0032] To ensure the stability of the feeding process, a square groove 12 is provided on the side of the C-shaped frame 2, and the square groove 12 passes through the second guide plate 4. The square groove 12 is distributed correspondingly to the feeding groove 5. A positioning plate 6 for assisting in the positioning of the crystal head body 14 is slidably installed inside the square groove 12. The positioning plate 6 can be inserted into the position between the crystal head body 14 and the spring contact (see reference). Figure 5A second electric cylinder 11 is fixedly connected to the base 1, and a positioning plate 6 is fixedly connected to the telescopic end of the second electric cylinder 11. The positioning plate 6 is moved by the second electric cylinder 11.
[0033] A push post 7 is slidably mounted on the C-shaped frame 2, and the push post 7 is attached to the first guide plate 3 and the second guide plate 4. A first electric cylinder 10 is fixedly connected to the base 1, and the push post 7 is fixedly connected to the telescopic end of the first electric cylinder 10. The push post 7 is moved by the first electric cylinder 10, and the push post 7 pushes the crystal head body 14 to slide on the first guide plate 3 and the second guide plate 4.
[0034] A punch 13 is slidably mounted on the top of the C-shaped frame 2, and a drive device, including an electric push rod (not shown in the figure), is provided on the C-shaped frame 2 to drive the punch 13 to move up and down. The punch 13 is used to press the copper sheet of the crystal head body 14.
[0035] The first electric cylinder 10, the second electric cylinder 11, and the drive equipment are all connected to the factory's power supply.
[0036] To limit the position of the crystal head body 14, a baffle 8 is fixedly connected to the end of the C-shaped frame 2 away from the push post 7. When the crystal head body 14 moves to the baffle 8, it is blocked by the baffle 8. A groove 9 is provided on the top of the baffle 8. The groove 9 is distributed in correspondence with the sliding gap. The width of the groove 9 is smaller than the width of the sliding gap. The network cable can pass through the groove 9 and connect to the crystal head body 14.
[0037] In actual use, automatic feeding is achieved using a vibratory feeder and vibratory guide rail. The positioning plate 6 extends into the sliding gap and can be inserted between the main body of the crystal head 14 and the spring contact (see reference). Figure 5 This ensures that the crystal head body 14 remains horizontal, with both sides of the bottom of the crystal head body 14 respectively abutting against the first guide plate 3 and the second guide plate 4; then, the first electric cylinder 10 drives the push column 7 to move towards the baffle 8, and the push column 7 abuts against the crystal head body 14. The positioning plate 6 quickly retracts, and the push column 7 pushes the crystal head body 14 to continue moving towards the baffle 8 and abutting against the baffle 8. The push column 7 and the baffle 8 cooperate to position the crystal head body 14, while the inner wall of the C-shaped frame 2 is positioned by the two sides of the crystal head body 14 (see reference). Figure 2 ).
[0038] Then, the operator manually passes the network cable through the groove 9 and into the square hole of the crystal head body 14; controls the punch 13 to move downward, squeezes the copper sheet on the crystal head body 14, presses the copper sheet tightly, then the punch 13 returns to its original position, the crystal head body 14 and the network cable are taken out together, and the push post 7 and other components return to their original positions.
[0039] Then connect the other RJ45 connectors 14 to the network cable following the steps described above.
[0040] This utility model, by setting up a positioning plate 6, a push column 7 and other structures, forms a sliding gap according to the shape characteristics of the crystal head body 14, and quickly feeds and clamps the crystal head body 14, ensuring the stability of the crystal head body 14 and the connection with the network cable, and improving the utilization efficiency of the crystal head forming mold.
[0041] Example 2, the present invention provides as follows Figures 7-8 The crystal head forming mold shown considers that after the crystal head body 14 is connected to the network cable, it is necessary to drag the network cable to bring out the crystal head body 14. It is easy to affect the stability of the connection between the crystal head body 14 and the network cable due to the large drag force. In order to realize the automatic pop-out of the crystal head body 14, the C-shaped frame 2 is provided with a pop-out component to assist the crystal head body 14 in being taken out, and the pop-out component is distributed correspondingly to the punch 13.
[0042] In specific configuration, the pop-up component includes a first sliding channel 15, a second sliding channel 17, and an inner cavity 20. The first sliding channel 15 and the second sliding channel 17 are both located on the upper surface of the bottom of the C-shaped frame 2. The second sliding channel 17 is connected to the sliding gap. The inner cavity 20 is located inside the wall of the C-shaped frame 2. The bottom ends of the first sliding channel 15 and the second sliding channel 17 are connected to the inner cavity 20. A pressure rod 16 is slidably installed inside the first sliding channel 15. The pressure rod 16 is L-shaped, and the top end of the pressure rod 16 abuts against the punch 13.
[0043] The second sliding channel 17 is internally slidably provided with a push rod 18. The top of the push rod 18 can be provided with a rubber pad or the like to reduce wear between it and the crystal head body 14. The bottom end of the push rod 18 is fixedly connected to the pressure rod 16. The bottom of the pressure rod 16 is fixedly connected to a spring 19. The bottom end of the spring 19 is fixedly connected to the bottom of the inner cavity 20.
[0044] In actual use, before pressing the copper sheet on the crystal head body 14, the punch 13 moves downward a certain distance, the punch 13 contacts the top of the pressure rod 16 and drives the pressure rod 16 and the push rod 18 to move downward, the spring 19 contracts, and at this time the top of the push rod 18 will not contact the spring sheet of the crystal head body 14.
[0045] After the pusher 7 and the baffle 8 work together to position the crystal head body 14, the punch 13 continues to move downward to squeeze the copper sheet on the crystal head body 14, and the pressure rod 16, push rod 18 and other components continue to move downward.
[0046] After the crystal head body 14 is connected to the network cable, the punch 13 moves upward to reset, and the bottom of the punch 13 does not contact the top of the pressure rod 16. At this time, the reset force of the spring 19 causes the push rod 18 to move upward and push out the crystal head body 14, making it easy for the operator to pick it up directly without pulling.
[0047] Next, the punch 13 moves downward a certain distance, and the punch 13 contacts the top of the pressure rod 16, causing the pressure rod 16 and the push rod 18 to move downward. At this time, the top of the push rod 18 will not contact the spring of the crystal head body 14, and the next round of operation will begin.
[0048] By setting up structures such as pop-out components, the movement of the punch 13 is used as power to push out the crystal head body 14, making it easy for operators to pick up directly and further improving the efficiency of the crystal head forming mold.
