Description

Technical Field

[0002] Existing electronic products all involve connecting wires between electronic components and circuit boards. The connecting wires can be directly plugged in and used, which is very convenient to use. Its structure usually includes a wire and a plastic shell. One end of the wire has solder and the other end has a terminal. The terminal is inserted into the plastic shell to form a connecting wire.

[0003] The processing of connecting wires needs to go through multiple processes such as wire stripping, wire cutting, terminal punching, and plugging in a plastic shell. There are various devices for plugging in a plastic shell in the prior art. In the existing plugging in a plastic shell device, a wire feeding device is provided. The wire feeding device is used to feed the connecting wire with the terminal punched to the plugging in a plastic shell device so as to insert the terminal of the connecting wire into the plastic shell. In order to fix the connecting wire and ensure the insertion of the terminal, the wire feeding device is provided with a fixing mechanism for clamping and fixing the connecting wire. However, the fixing mechanism cannot clamp the connecting wire fixed at the root of the terminal, so that after the fixing mechanism clamps the connecting wire, the connecting wire exposed outside the fixing mechanism on one side of the terminal is longer, such as Figure 8 In the prior art, in the clamping state of the connecting wire, the root of the terminal 200 of the connecting wire 100 is far away from the fixing mechanism 300, which causes the connecting wire to be easily twisted, offset, misaligned, etc. during the plugging process, which affects the plugging accuracy.

In this way, the first clamping and fixing unit, the second clamping and fixing unit and the shifting mechanism 40 of the clamping mechanism 20 are combined to stably position the connecting wire. In particular, the clamping mechanism 20 is designed to be linked with the shifting mechanism 40 so that the clamping mechanism 20 can be displaced toward the root of the terminal 500 of the connecting wire 400, so that the clamping mechanism 20 can stably clamp the connecting wire 400 at the root of the terminal 500, so that the exposed connecting wire 400 is shorter (such as Fig. 9 As shown in the figure, it avoids the phenomenon that the connection wire is soft and thus may cause distortion, deviation, dislocation and other problems that may affect the insertion accuracy during the insertion process of the plastic shell, and enables the terminal to be inserted into the plastic shell more accurately and firmly.

A reset spring 26 is provided on the clamping seat 24; one end of the reset spring 26 is fixed to the clamping seat 24, and the other end is connected to the linkage part 231 on one side of the lower clamping and fixing unit 23.

[0061] The clamping mechanism 20 also includes a receiving plate 27, which is located at the front side of the connecting seat 14. The clamping and fixing unit and the clamping drive unit 21 are both installed on the receiving plate 27. A second slider 28 is connected below the receiving plate 27, and the second slider 28 is adapted to the slide rail 16. The displacement drive unit 41 is installed on the receiving plate 27. The displacement unit is a displacement rod 42. One end of the displacement rod 42 is connected to the displacement drive unit 41, and the other end is connected to the connecting seat 14. And the clamping seat 24 is fixed to the upper end of the receiving plate 27. In this way, the moving mechanism 10 can drive the clamping mechanism 20 to move as a whole.

[0062] A wire pressing mechanism 50 is arranged on the rear side of the wire clamping mechanism 20, and the wire pressing mechanism 50 is connected to the top of the moving unit, and the wire pressing mechanism 50 includes a wire pressing unit and a wire pressing driving unit 51 for driving the wire pressing unit; the wire pressing unit is located on the rear side of the clamping and fixing unit, and the wire pressing unit includes a first wire pressing unit and a second wire pressing unit, and the wire pressing driving unit 51 drives the first wire pressing unit and the second wire pressing unit to selectively open and close, so as to clamp or release the connecting wire 400.

[0063] Specifically, the first wire pressing unit and the second wire pressing unit are respectively defined as an upper wire pressing unit 52 and a lower wire pressing unit 53, the upper wire pressing unit 52 is connected to the wire pressing driving unit 51, and the lower wire pressing unit 53 is limited by the lower side of the connecting line 400, the upper wire pressing unit 52 is located on the rear side of the upper clamping and fixing unit 22, and the lower wire pressing unit 53 is located on the rear side of the lower clamping and fixing unit 23. The upper wire pressing unit 52 can be selectively displaced downward in the up and down direction under the drive of the wire pressing driving unit 51 to clamp on the upper side of the connecting line 400 or displaced upward to release the clamping of the connecting line 400. In this way, the middle part of the connecting wire 400 can be firmly clamped and positioned through the combined design of the upper pressing unit 52 and the lower pressing unit 53, thereby combining the aforementioned upper clamping and fixing unit 22 and the lower clamping and fixing unit 23 to firmly position the connecting wire 400, thereby avoiding the phenomenon of misalignment, distortion, etc. that affects the accuracy due to the insufficient positioning of the connecting wire 400 during the plug-in process.

[0067] The general working process is as follows:

[0068] First, the wire feeding mechanism 30 feeds the connecting wire 400 from the back to the front until the head of the connecting wire 400 is exposed outside the wire clamping unit; then, the upper wire pressing unit 52 of the wire pressing mechanism 50 presses the middle part of the connecting wire 400 onto the lower wire pressing unit 53, and then, the terminal is crimped; after the terminal 500 is crimped, the shifting mechanism 40 drives the wire clamping mechanism 20 to move forward as a whole, so that the clamping and fixing unit of the wire clamping mechanism 20 moves to the connecting wire 400 at the root of the terminal 500, and then, the clamping driving unit 21 drives the lower clamping and fixing unit 23 to move upward, so that the upper clamping and fixing unit 22 and the lower clamping and fixing unit 23 are clamped together at the connecting wire 400 at the root of the terminal 500, as shown in FIG. Fig. 9 In this way, after the connecting wire 400 at the root of the clamping terminal 500 is clamped, the process of clamping the terminal and then inserting the plastic shell can be carried out.

[0069] To sum up, the design focus of the present invention is that it mainly uses the combined design of the first clamping and fixing unit, the second clamping and fixing unit and the shifting mechanism of the wire clamping mechanism to enable it to firmly position the connecting wire. In particular, through the design of the shifting mechanism linking the wire clamping mechanism, the wire clamping mechanism can be displaced toward the root of the terminal of the connecting wire, so that the wire clamping mechanism can firmly clamp the connecting wire at the root of the terminal, making the exposed connecting wire shorter, avoiding the phenomenon of distortion, offset, dislocation, etc. of the connecting wire being soft and affecting the insertion accuracy during the plug-in process of the plastic shell, and allowing the terminal to be inserted into the plastic shell more accurately and firmly.
