Under the arrangement of the two pressing plates 107, the vertical sliding of the guide rail 109 can be guided, thereby ensuring the stability of the guide rail 109 when it slides vertically. The outer surface of each guide rail 109 is slidably provided with two sliders 105, each slider 105 is horizontally slidably arranged inside the outer shell component 4, so that the two guide rails 109 can drive each slider 105 to slide horizontally when sliding vertically, so that each slider 105 is close to the middle of the outer shell component 4, thereby completing the power transmission to the inner shell component 5, and each slider 105 is fixedly connected to a guide shaft 103 on a side close to the side plate 44, and the guide shaft 103 passes through the first body 41 and the side plate 44, and the outer surface of each guide shaft 103 is wrapped with an elastic member, and one end of the elastic member is fixedly connected to the side plate The outer surface of 44 can play an elastic reset effect on the slider 105 under the setting of the guide shaft 103 and the elastic member.

A hanging head assembly 3 is installed on the upper surface of the connecting plate 106. The hanging head assembly 3 adopts a disc hanging head, which matches the standard crimping machine and is conveniently height-adjustable.

[0036] The crimping mechanism 2 includes an upper slide rail 201, a first crimping core 202, three lower slide rails 203, and three second crimping cores 204. The upper slide rail 201 is horizontally slidably arranged inside the inner shell component 5, the first crimping core 202 is vertically slidably arranged inside the inner shell component 5, the two lower slide rails 203 on the left and right sides are both vertically slidably arranged inside the inner shell component 5, the two second crimping cores 204 on the left and right sides are both horizontally slidably arranged inside the inner shell component 5, the second crimping core 204 located at the bottom is vertically slidably arranged inside the inner shell component 5, and the lower lower rail 203 located at the bottom is horizontally slidably arranged inside the inner shell component 5, and the first crimping core 202 and the three second crimping cores 204 are driven by the upper slide rail 201 and the three lower slide rails 203 under common sliding. The two crimping cores 204 are moved closer to the middle part of the inner shell assembly 5, so that the first crimping core 202 and the three second crimping cores 204 can be crimped to the terminal. A cross groove and four placement grooves are provided on the front of the crimping shell 51, and the cross groove is connected with the four placement grooves, so that the upper slide rail 201, the first crimping core 202, each lower rail 203 and each second crimping core 204 can be placed in the corresponding grooves respectively, so as to complete the motion transmission between each accessory, and it is more convenient to assemble. The upper slide rail 201 and the three lower rails 203 are respectively slidably set in the four placement grooves on the front side of the crimping shell 51, and the upper slide rail 201 will be located in the uppermost layer of the placement groove. A guide groove is provided on the back of the crimping shell 51, and the interior of the upper slide rail 201 is slidably set on the crimping shell 51 through a latch. The guide groove of the connecting shell 51 makes the upper slide rail 201 more stable when moving, and has a good guiding and limiting effect on the upper slide rail 201. The first crimping core 202 and the three second crimping cores 204 are respectively slidably arranged in the cross groove on the front side of the first main body 41, so that the first crimping core 202 and the three second crimping cores 204 are in a cross shape after being placed, so as to facilitate the crimping of the terminal. The upper slide rail 201 corresponds to the first crimping core 202, and the three lower slide rails 203 correspond to the three second crimping cores 204 one by one. The end of each slider 105 away from the side plate 44, the two ends of the upper slide rail 201, the top of the first crimping core 202, the ends of the three second crimping cores 204 away from each other and the two ends of each lower slide rail 203 are all provided with bevel edges. One end of the four sliders 105 is in contact with one end of the three lower slide rails 203 and the upper slide rail 201 respectively, so that when the two guide rails 109 slide vertically downward, each slider 105 can be driven to move closer to the middle, so that each slider 105 pushes the upper slide rail 201 and the three lower slide rails 203 to move respectively, and further makes the upper slide rail 201 and the three lower slide rails 203 push the first crimping core 202 and the three second crimping cores 204. Each second crimping core 204 is provided with an elastic reset component that automatically resets the second crimping core 204 after sliding. The elastic reset component includes a stop pin and a spring, which are connected to each other, and the stop pin and the spring are fixedly connected to the inside of the second crimping core 204, and the stop pin is fixedly connected to the inner wall of the crimping shell 51.Under the setting of the elastic reset component, after the terminal is crimped, the second crimping core 204 can be automatically reset, so that each second crimping core 204 will be away from each other, so as to facilitate the subsequent crimping of other terminals.

[0037] The upper limit block 102 is fixedly connected to the back of the connecting plate 106, and the pressure block 108 is fixedly connected to the back of the upper limit block 102. An upper punch 104 is slidably arranged between the upper limit block 102 and the pressure block 108, and the top of the upper punch 104 passes through the pressure block 108 and the upper limit block 102. The inner bottom wall of the upper punch 104 is fixedly connected with an elastic member, and the top of the elastic member is fixedly connected to the inner top wall of the upper limit block 102. The bottom end of the upper punch 104 is located directly above the first crimping core 202, so that the upper punch 104 first presses the first crimping core 202 to For downward extrusion, a groove matching the first crimping core 202 is formed on the upper surface of the first main body 41, so that the first crimping core 202 can slide up and down in the groove, and a lower limit block 101 is fixedly connected in the groove, and the lower limit block 101 has a limiting and blocking effect on the upper punch 104. The rear end of the first crimping core 202 is slidably set on the inner wall of the lower limit block 101, and an elastic part is fixedly connected to the inner top wall of the first crimping core 202, and the elastic part is fixedly connected to the groove on the upper surface of the first main body 41, which can make the first crimping core 202 have an elastic reset effect.

[0038] During operation, the connecting plate 106 and the hanging head assembly 3 are driven downward by the action of the crimping machine. When the hanging head assembly 3 just moves downward, the upper punch 104 moves downward under the action of the internal elastic member, and the bottom end of the upper punch 104 pushes the first crimping core 202 to move downward. When the bottom end of the upper punch 104 contacts the lower limit block 101, the movement stops. At this time, when the two guide rails 109 slide vertically downward, they will drive each slider 105 to move closer to the middle, and then each slider 105 will push the upper slide rail 201 and the three lower slide rails 203 to move, further making the upper slide rail 201 and the three lower slide rails 203 move. The lower sliding rail 203 relies on its own inclined surface to push the first crimping core 202 and the three second crimping cores 204, and together completes the crimping action of the terminal under the action of the three lower sliding rails 203 and the first crimping core 202, so that the terminal is crimped like a conventional terminal without the need for additional action, which greatly improves the crimping efficiency of the terminal and ensures the consistency of the crimping quality. The elastic wedge block structure is adopted to fully avoid the right-angle protruding part, and the transmission mechanism 1 and the crimping mechanism 2 adopt an inclined surface structure to convert the up and down movement of the hanging head assembly 3 into the horizontal and vertical movement of the first crimping core 202 and the three lower sliding rails 203.
