A pin hole 141 is provided on the side wall of the wire threading sleeve 14, and an electric locking pin device (not shown in the figure) is provided at the pin hole 141. The locking pin of the electric locking pin device is inserted into the pin hole 141.

[0032] Specifically, the cross-sectional contour of the outer skin of the wire 4 is rectangular, the contour of the profiling perforation 142 corresponds to the cross-sectional contour of the outer skin of the wire 4, and two electric wires 41 are wrapped inside the outer skin of the wire 4.

[0033] Specifically, the base is provided with a horizontal lead screw mechanism 15, and the lead screw nut of the horizontal lead screw mechanism 15 is fixedly connected with the horizontal slide 11. The horizontal slide 11 is provided with a longitudinal lead screw mechanism 16, and the lead screw nut of the longitudinal lead screw mechanism 16 is fixedly connected with the longitudinal slide 12.

[0034] Specifically, the base is fixedly connected with two vertical blocks 26. The two vertical blocks 26 are distributed horizontally. The vertical blocks 26 are arranged longitudinally. A guiding slide rail is fixedly connected to the top side edge of the vertical block 26, and a slide block 211 is slidably connected to the guiding slide rail. One slide block 211 is fixedly connected to the bottom walls of the two lateral sides of the top plate 21 respectively. A longitudinal fine-tuning cylinder 27 is provided between the two vertical blocks 26, and the piston rod of the longitudinal fine-tuning cylinder 27 is fixedly connected to the bottom wall of the top plate 21.

[0035] Specifically, a wire pressing cylinder 28 is fixedly connected to the rear side of the crimping cylinder 24. The piston rod of the wire pressing cylinder 28 is fixedly connected with a wire pressing block 281, and an arc-shaped limiting notch 282 is provided on the bottom wall of the wire pressing block 281.

[0036] Specifically, two mounting bases 13 are fixedly connected to the top wall of the longitudinal slide 12. The two mounting bases 13 are distributed horizontally.

[0037] Specifically, each mounting base 13 is provided with two wire threading sleeves 14.

[0038] The working principle of the terminal press of the present utility model is as follows:

[0039] Thread the wire 4 into the wire threading sleeve 14, so that the front section of the wire 4 extends out of the wire threading sleeve 14, and the two wires 41 of the wire 4 are exposed (as Figure 2 shown). Then, the locking pin of the electric locking pin device (not shown in the figure) provided at the pin hole 141 is inserted into the pin hole 141, thereby pressing the wire 4 tightly.

[0040] Place the strip 3 on the transverse notch 221 (the opening 311 of the terminal 31 faces the wire 4), and one end of the strip 3 is pulled by other devices, so as to intermittently move along the transverse notch 221.

[0041] When two of the terminals 31 of the strip 3 move to the notches of the two lower crimping grooves 231, the strip 3 stops advancing. Then, the mounting base 13 is driven by the transverse slide 11 and the longitudinal slide 12 to move downward in the direction of the lower module 23. Then, the piston rod of the crimping cylinder 28 extends, driving the crimping block 281 to move downward, so that the arc-shaped limiting notch 282 moves downward to a suitable position. At this time, the mounting base 13 moves forward to drive the two wires 41 to move forward along the arc surface of the arc-shaped limiting notch 282, and then respectively contact the two inclined surfaces of the separating pointed strip 232, so as to be separated into two paths by the separating pointed strip 232, and then respectively enter the openings 311 of the two terminals 31. The arc-shaped limiting notch 282 abuts against the top sides of the two wires 41, restricting the upward swing of the wires 41 and ensuring that the front ends of the two wires 41 respectively contact the two inclined surfaces of the separating pointed strip 232. Then, the crimping cylinder 24 drives the upper module 25 to move downward, so that the two upper crimping grooves 251 and the two lower crimping grooves 231 jointly squeeze the two terminals 31, causing the two terminals 31 to converge and deform to anchor to the ends of the two wires 41, thereby realizing the connection between the terminals 31 and the wires 41.

[0042] During the downward pressing of the upper module 25, the shearing flange 252 enters the shearing notch 234, and the shearing flange 252 and the shearing notch 234 jointly cut off the connecting section at the end of the terminal 31, so that the terminal 31 anchored to the wire 41 is separated from the strip 3.

[0043] The wire threading sleeve 14 of the terminal press of the present utility model can quickly place and clamp the wire 4. The wire pressing block 281 and the separating pointed bar 232 cooperate to effectively separate two wires 41 and respectively enter two terminals 31, so as to realize the pressing of two terminals 31 at the ends of two wires 41 at one time, thereby improving the efficiency of terminal pressing, reducing labor consumption and cost. The two inclined surfaces of the separating pointed bar 232 can guide the separation of two wires 41 to a proper distance, so that both wires 41 can be accurately inserted into their corresponding terminals 31 to ensure the pressing quality.

[0044] The above is only the preferred embodiment of the present utility model and does not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to obtain equivalent embodiments with equivalent changes. However, as long as it does not depart from the technical content of the present utility model, any brief modification, equivalent change and modification made to the above embodiment based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
