[0009] Preferably, the upper ends of the limiting inclined blocks are all inserted with limiting rods, and the ends of the limiting rods close to each other are slidably connected to the female terminals.

[0010] Preferably, through grooves are symmetrically provided front and back on the right side of the female terminal corresponding to the slot, and protective plates are fixedly installed on the lower ends of the limiting inclined blocks corresponding to the through grooves.

[0011] Preferably, a nozzle tube is provided at the front side of the female terminal corresponding to the through groove, an upper end of the nozzle tube is connected to an air bag, and a left end of the air bag is fixedly connected to a fixing frame.

[0012] Preferably, a pressure plate is fixedly mounted on the right end of the airbag, and a top strip is fixedly mounted on the left end of the movable frame corresponding to the pressure plate.

[0013] Preferably, a connecting rod 2 is fixedly installed symmetrically at the left end of the pressure plate, the left end of the connecting rod 2 is slidably installed on the fixed frame, and a spring 4 is sleeved on the outer side of the connecting rod 2.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the female terminal and the tapping terminal are pressed onto the fixed frame and the movable frame from the upper ends of the fixed frame and the movable frame respectively. Since the inclined surface of the upper end of the inclined fixed block 1 is subjected to the squeezing force of the female terminal and the tapping terminal, the connecting rod 1 will be driven to slide forward and compress the spring 1 until the lower ends of the female terminal and the tapping terminal are respectively fitted with the inner bottom ends of the fixed frame and the movable frame. Then, the inclined fixed block 1 and the connecting rod 1 will slide backward and reset under the action of the spring 1, so that the inclined fixed block 1 is respectively inserted into the female terminal and the tapping terminal, which is convenient for automatically fixing the female terminal and the tapping terminal, improving the crimping efficiency, and automatically aligning and adjusting the crimping horizontal angles of the female terminal and the tapping terminal to ensure the subsequent crimping quality.

[0017] The second spring is pressed against the second end of the guide rail and the second end of the guide rail is pressed against the second end of the guide rail, and the second end of the guide rail is pressed against the second end of the guide rail, and the second end of the guide rail is pressed against the second end of the guide rail, and the second end of the guide rail is pressed against the second end of the guide rail.

[0018] 3. In the present invention, when the oblique fixed block 2 rises, it will contact and push the limit rod to slide upward on the female terminal. When the limit rod is separated from the limit oblique block, under the action of spring 3, the limit oblique block is pushed to move to the right. At this time, the right end inclined surface of the limit oblique block will move to the lower left end of the oblique fixed block 2. When the oblique fixed block 2 slides downward and resets under the action of spring 2, the elastic force of spring 2 is greater than that of spring 3, so the oblique fixed block 2 will squeeze and pass over the right end inclined surface of the limit oblique block (the limit oblique block will slide to the left and compress spring 3). When the second reset is inserted into the fixed groove block, the upper end of the inclined fixing block two will be lower than the lower end of the limiting inclined block. At this time, the limiting inclined block will reset to the right under the action of spring three, and the lower end of the limiting inclined block is located on the upper side of the inclined fixing block two, which is conducive to preventing the inclined fixing block two from detaching from the fixed groove block due to accidental collision, thereby ensuring that the inclined fixing block two can be stably inserted into the fixed groove block, thereby ensuring the stability of the crimping between the female terminal and the tapping terminal, ensuring the crimping quality of the female terminal and the tapping terminal, and can be flexibly and independently disassembled, with strong applicability.

[0019] 4. In the present invention, when the movable frame moves to the left, it will also drive the top bar to move to the left synchronously. The top bar will contact the pressure plate and squeeze the pressure plate to drive the connecting rod 2 to slide to the left, compressing the spring 4 and the airbag. The gas is ejected from the nozzle tube, which is convenient for ejecting dust and debris in the female terminal slot to the outside through the through groove, ensuring that the subsequent tapping terminal and the female terminal can contact and conduct electricity smoothly, thereby improving the crimping quality between the coupler terminals.

[0020] 5. In the present invention, when the limiting inclined block moves to the right, it will also drive the protective plates on both sides to move to the right synchronously, so as to block the through slots on both sides and prevent external dust and humid air from entering through the through slots during subsequent use, resulting in rust on the conductive head, poor contact of the wires and short circuit.

[0021] 6. In the present invention, when the movable frame moves to the left, the telescopic rods arranged on both sides will shrink adaptively. The telescopic rods ensure that the movable frame can slide stably horizontally, thereby preventing the tapping terminal from being unable to be smoothly inserted into the female terminal due to the misalignment of the angle of the movable frame, and preventing the tapping terminal from being tilted at an angle, resulting in greater wear during the plug-in process, thereby affecting the crimping quality between the terminals.

[0022] 7. In the present invention, when the telescopic rod adaptively contracts, it will also drive the cleaning ring, the fixed ring and the support block to move synchronously. The cleaning ring is convenient for cleaning the debris and dust adhered to the outer surface of the telescopic rod, so as to avoid the debris and dust affecting the normal extension and retraction of the telescopic rod, and the telescopic rod is not smoothly extended when extending and retracting, thereby affecting the subsequent terminal crimping quality.

[0023] 8. In the present invention, when the fixed ring moves to the left, it will also drive the magnetic block 1 to move synchronously. When the magnetic block 1 is close to one side of the magnetic block 2, it will be subjected to the magnetic repulsive force, pushing the magnetic block 1 to move in the direction of approaching each other, thereby driving the fixed ring and the cleaning ring to slide on the support block and compress the spring 5. The set spring 5 plays a resetting role, so that the cleaning ring can reciprocate when sliding on the retracting rod, thereby improving the cleaning quality of the debris and dust on the surface of the retracting rod, thereby improving the subsequent terminal crimping quality.

Since the inclined surface of the upper end of the oblique fixing block 5 is squeezed by the female terminal 201 and the tapping terminal 301, the connecting rod 6 is driven to slide forward and the spring 7 is compressed until the lower ends of the female terminal 201 and the tapping terminal 301 are respectively fitted with the inner bottom ends of the fixed frame 2 and the movable frame 3. Then, the oblique fixing block 5 and the connecting rod 6 are slid backward and reset under the action of the spring 7, so that the oblique fixing block 5 is respectively inserted into the female terminal 201 and the tapping terminal 301, so as to automatically fix the female terminal 201 and the tapping terminal 301, thereby improving the crimping efficiency and automatically aligning and adjusting the female terminal 201 and the tapping terminal 301. The horizontal angle of crimping is ensured to ensure the subsequent crimping quality. The electric push rod 4 is started to drive the movable frame 3 to slide in the direction of the fixed frame 2. The movable frame 3 will drive the tapping terminal 301 to move synchronously toward the female terminal 201 until the conductive head of the tapping terminal 301 is successfully inserted into the slot of the female terminal 201. At the same time, the tapping terminal 301 will also drive the fixed slot blocks 8 on both sides to move synchronously to the left. The fixed slot blocks 8 will gradually contact the inclined surfaces of the oblique fixed blocks 29 and squeeze the inclined surfaces of the oblique fixed blocks 29, pushing the oblique fixed blocks 29 to slide upward on the female terminal 201 and compressing the springs 210 until the fixed slot at the upper end of the fixed slot block 8 passes over the lower end of the oblique fixed block 29. Under the action of the springs 210, the oblique fixed blocks 29 are pushed downward to be clamped in the fixed slots The tapping terminal 301 is completely inserted into the female terminal 201, and the electric push rod 4 stops pushing the movable frame 3 to complete the crimping work between the tapping terminal 301 and the female terminal 201.

When the inclined fixing block 2 9 rises, it will contact and push the limiting rod 13 to slide upward on the female terminal 201. When the limiting rod 13 is separated from the limiting inclined block 11, under the action of the spring 3 12, the limiting inclined block 11 is pushed to move to the right. At this time, the inclined surface of the right end of the limiting inclined block 11 will move When the inclined fixing block 29 is moved to the lower left end of the inclined fixing block 29, when the inclined fixing block 29 slides downward and resets under the action of the spring 210, the elastic force of the spring 210 is greater than the spring 312, so the inclined fixing block 29 will squeeze and pass over the right end inclined surface of the limiting inclined block 11 (the limiting inclined block 11 will slide to the left and compress the spring 312). When the inclined fixing block 29 is reset and inserted into the fixed groove block 8, the upper end of the inclined fixing block 29 will be lower than the lower end of the limiting inclined block 11. At this time, the limiting inclined block 11 will reset to the right under the action of the spring 312. The lower end of the limiting inclined block 11 is located on the upper side of the inclined fixing block 29, which is conducive to preventing the inclined fixing block 29 from detaching from the fixed groove block 8 due to accidental collision, thereby ensuring that the inclined fixing block 29 can be stably inserted into the fixed groove block 8.Thus, the stability after crimping between the female terminal 201 and the tapping terminal 301 is ensured, and the crimping quality between the female terminal 201 and the tapping terminal 301 is ensured.

The telescopic rods 21 ensure that the movable frame 3 can slide stably horizontally, and avoid that the tapping terminal 301 cannot be inserted into the female terminal 201 normally and smoothly due to the misalignment of the angle of the movable frame 3, and the tapping terminal 301 is tilted, resulting in greater wear during the plug-in process, affecting the crimping quality between the terminals. When the telescopic rod 21 shrinks adaptively, it will also drive the cleaning ring 22, the fixing ring 23 and the supporting block 24 to move synchronously. The cleaning ring 22 is convenient for cleaning the debris and dust adhered to the outer surface of the telescopic rod 21, and avoids the debris and dust affecting the telescopic rod. The normal extension and retraction of the telescopic rod 21, and the situation that the extension and retraction of the telescopic rod 21 are not smooth, thereby affecting the subsequent terminal crimping quality. When the fixed ring 23 moves to the left, it will also drive the magnetic block 1 26 to move synchronously. When the magnetic block 1 26 is close to the side of the magnetic block 27, it will be subjected to the magnetic repulsion force, pushing the magnetic block 1 26 to move in the direction of approaching each other, thereby driving the fixed ring 23 and the cleaning ring 22 to slide on the support block 24, compressing the spring five 25. The set spring five 25 plays a resetting role, so that the cleaning ring 22 can also reciprocate when sliding on the telescopic rod, thereby improving the cleaning quality of the debris and dust on the surface of the telescopic rod, thereby improving the subsequent terminal crimping quality.

[0029] Working principle: When the present invention is used, the female terminal 201 and the tapping terminal 301 are pressed onto the fixed frame 2 and the movable frame 3 from the upper ends of the fixed frame 2 and the movable frame 3, respectively. Since the inclined surface of the upper end of the oblique fixing block 5 is subjected to the extrusion force of the female terminal 201 and the tapping terminal 301, it will drive the connecting rod 6 to slide forward and compress the spring 7 until the lower ends of the female terminal 201 and the tapping terminal 301 are respectively attached to the inner bottom ends of the fixed frame 2 and the movable frame 3. Then, the oblique fixing block 5 and the connecting rod 6 will slide backward and reset under the action of the spring 7, so that the oblique fixing block 5 is respectively inserted into the female terminal 201 and the tapping terminal 301, which is convenient for automatically fixing the female terminal 201 and the tapping terminal 301, thereby improving the crimping efficiency and automatically aligning and adjusting the female terminal 201 and the tapping terminal 301. 1, to ensure the subsequent crimping quality, start the electric push rod 4 to drive the movable frame 3 to slide in the direction of the fixed frame 2, and the movable frame 3 will drive the tapping terminal 301 to move synchronously toward the female terminal 201, until the conductive head of the tapping terminal 301 is smoothly inserted into the slot of the female terminal 201. At the same time, the tapping terminal 301 will also drive the fixed slot blocks 8 on both sides to move synchronously to the left, and the fixed slot blocks 8 will gradually contact the inclined surfaces of the inclined fixed blocks 29 and squeeze the inclined surfaces of the inclined fixed blocks 29, pushing the inclined fixed blocks 29 to slide upward on the female terminal 201, compressing the springs 210, until the fixed slot at the upper end of the fixed slot block 8 passes over the lower end of the inclined fixed block 29, and under the action of the springs 210, the inclined fixed blocks 29 are pushed to slide downward and snap into the fixed When the tapping terminal 301 is on the slot block 8, the tapping terminal 301 is also completely inserted into the female terminal 201, and the electric push rod 4 stops pushing the movable frame 3 to complete the crimping work between the tapping terminal 301 and the female terminal 201. The fixed slot block 8 and the inclined fixed block 29 cooperate with each other, which is beneficial to improve the firmness of the crimping between the tapping terminal 301 and the female terminal 201, ensuring the stable electrical conduction between the tapping terminal 301 and the female terminal 201, thereby ensuring the crimping quality of the coupler terminal. When the inclined fixed block 29 rises, it will contact and push the limiting rod 13 to slide upward on the female terminal 201. When the limiting rod 13 is separated from the limiting inclined block 11, under the action of the spring 3 12, the limiting inclined block 11 is pushed to move to the right. At this time, the inclined surface of the right end of the limiting inclined block 11 will When the inclined fixing block 29 moves to the lower left side of the inclined fixing block 29, when the inclined fixing block 29 slides downward and resets under the action of the spring 210, the elastic force of the spring 210 is greater than the spring 312, so the inclined fixing block 29 will squeeze and pass over the right end inclined surface of the limiting inclined block 11 (the limiting inclined block 11 will slide to the left and compress the spring 312). When the inclined fixing block 29 is reset and inserted into the fixed groove block 8, the upper end of the inclined fixing block 29 will be lower than the lower end of the limiting inclined block 11. At this time, the limiting inclined block 11 will reset to the right under the action of the spring 312. The lower end of the limiting inclined block 11 is located on the upper side of the inclined fixing block 29, which is conducive to preventing the inclined fixing block 29 from detaching from the fixed groove block 8 due to accidental collision, thereby ensuring that the inclined fixing block 29 can be stably inserted into the fixed groove block 8.Thus, the stability of the crimping between the female terminal 201 and the tapping terminal 301 is ensured, and the crimping quality between the female terminal 201 and the tapping terminal 301 is ensured. When the movable frame 3 moves to the left, it will also drive the top strip 181 to move to the left synchronously. The top strip 181 will contact the pressure plate 18 and squeeze the pressure plate 18 to drive the connecting rod 2 19 to slide to the left, compressing the spring 4 20 and the air bag 17, and the gas is ejected from the nozzle tube 16, which is convenient for ejecting dust and debris in the slot of the female terminal 201 to the outside through the through groove 14, thereby ensuring the subsequent crimping between the tapping terminal 301 and the female terminal 201 The conductive contacts 15 are connected to the connector 11 and the connector 12 is connected to the connector 13. The conductive contacts 15 are connected to the connector 13 and the connector 13 is connected to the connector 13. The conductive contacts 15 are connected to the connector 13 and the connector 13 is connected to the connector 13. The conductive contacts 15 are connected to the connector 13 and the connector 13 is connected to the connector 13. 3. The angles are not aligned, resulting in failure to be inserted into the female terminal 201 smoothly and normally, and the tapping terminal 301 is tilted, resulting in greater wear during the plugging process, affecting the crimping quality between the terminals. When the telescopic rod 21 is adaptively contracted, it will also drive the cleaning ring 22, the fixing ring 23 and the support block 24 to move synchronously. The cleaning ring 22 is set to facilitate cleaning of the debris and dust adhered to the outer surface of the telescopic rod 21, so as to avoid the debris and dust affecting the normal extension of the telescopic rod 21, and the telescopic rod 21 is not smoothly extended when it is extended, thereby affecting The subsequent terminal crimping quality is improved when the fixing ring 23 moves to the left, which will also drive the magnetic block 1 26 to move synchronously. When the magnetic block 1 26 is close to the side of the magnetic block 2 27, it will be subjected to magnetic repulsion, pushing the magnetic block 1 26 to move in a direction close to each other, thereby driving the fixing ring 23 and the cleaning ring 22 to slide on the support block 24, compressing the spring 5 25. The spring 5 25 is set to play a reset role, so that the cleaning ring 22 can also reciprocate when sliding on the retracting rod, improving the cleaning quality of the debris and dust on the surface of the retracting rod, thereby improving the subsequent terminal crimping quality.
