Technical Field

[0001] This invention relates to the field of connector processing technology, and in particular to a terminal implantation device and terminal production line for new energy connectors. Background Technology

[0002] New energy connectors are commonly referred to as large connectors (generally referring to connectors with thicker wire diameters and larger terminals, often used in high-current / high-voltage applications such as new energy vehicles, industrial equipment, and other energy devices). During production, connector terminals need to be cut and separated from the material strip, and then the cut terminals are transported to the insertion station.

[0003] However, in actual production, starting from the cutting process, slight fluctuations in the material strip can cause terminal cutting defects, which will continuously affect subsequent terminal handling and insertion, bringing a series of problems to connector production.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

These terms are primarily for the purpose of better describing the invention and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0022] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0024] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0025] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0026] Example In high-current, high-voltage applications such as new energy vehicles and industrial energy storage, connector terminals typically have large physical dimensions and high material rigidity. These terminals are often produced continuously in the form of strips. In the actual cutting process, due to the physical inertia of the strip during high-speed feeding, the strip may float or oscillate as it is conveyed to the cutting station, leading to dimensional deviations in the cutting. This can cause deviations in subsequent steps, such as when the terminal is inserted into the sleeve, resulting in a decrease in connector yield.

[0027] Therefore, this invention discloses a new energy connector terminal implantation device, referring to... Figure 1The terminal implantation device includes a frame 100, on which a cutting unit 200, a conveying unit 300, and a plugging unit 400 are mounted. The cutting unit 200 is used to cut the terminal from the material strip 260, the plugging unit 400 is used to insert the terminal into the rubber sleeve, and the conveying unit 300 is used to receive the terminals falling from the material strip 260 and collect the terminals in batches and transport them to the plugging unit 400, so that the terminals can be inserted into the rubber sleeve in batches.

[0028] Reference Figure 2 The frame 100 is equipped with a feeding rail that extends horizontally to guide the strip 260 with terminals installed. The inner dimensions of the feeding rail match the width and thickness of the strip 260, forming a sliding channel for the strip 260.

[0029] Specifically, in one embodiment of the invention, reference is made to Figure 2 A first drive structure 210 and a second drive structure 220 are sequentially arranged along the extension direction of the feeding rail. The first drive structure 210 is mounted on the frame 100 and located upstream of the feeding rail, used for the initial feeding of the strip 260. The second drive structure 220 is mounted on the frame 100 and located downstream of the first drive structure 210, responsible for pulling out the strip 260. A cutting structure 230 is arranged between the first drive structure 210 and the second drive structure 220. The first drive structure 210 and the second drive structure 220 synchronously convey the strip 260, thereby tensioning the strip 260 between the first drive structure 210 and the second drive structure 220. That is, the strip 260 is in a tensioned state at the cutting mechanism, which results in higher consistency of the cut terminals when the cutting structure 230 cuts the strip 260.

[0030] Specifically, in one embodiment of the invention, reference is made to Figure 3 and Figure 4 The first drive structure 210 includes a first feeding motor 211 and a first feeding gear 212, and the second drive structure 220 includes a second feeding motor 221 and a second feeding gear 222. The first feeding gear 212 and the second feeding gear 222 respectively mesh with the preset positioning holes 261 on the material belt 260 through their teeth. The first feeding motor 211 and the second feeding motor 221 run synchronously.

[0031] Furthermore, in one embodiment of the invention, in order to achieve better tensioning of the strip 260 at the cutting position, the rotational speed or output torque of the second drive structure 220 is slightly greater than that of the first drive structure 210, thereby generating a continuous tensile force between the two, so that the strip 260 to be processed is always in close contact with the reference surface of the feeding rail and is in a controlled tensioning state.

[0032] Of course, in one embodiment of the present invention, when the rotational speed or output torque of the second drive structure 220 is slightly greater than that of the first drive structure 210, the tension force on the material belt 260 is much less than the strength threshold of the material belt 260, thus avoiding deformation of the material belt 260.

[0033] Furthermore, in one embodiment of the invention, reference is made to... Figure 3 and Figure 4 A cover plate 110 is also installed on the frame 100. The cover plate 110 covers the feed rail and confines the material belt 260 within the flat space formed between the feed rail and the cover plate 110. The cover plate 110 effectively prevents the material belt 260 from arching vertically during conveying. To ensure that the first feed gear 212 and the second feed gear 222 can smoothly engage with the material, the cover plate 110 has through holes at the positions of the corresponding gears, allowing the gear teeth to pass through the cover plate 110 and mesh with the material belt 260.

[0034] Specifically, in one embodiment of the invention, reference is made to Figure 5 and Figure 6 The cutting structure 230 includes a mounting plate 231 slidably mounted on the frame 100. The mounting plate 231 is connected to the frame 100 via a slide rail, and is mounted on the output end of the drive unit 233. The drive unit 233 drives the mounting plate 231, allowing it to reciprocate only in a direction perpendicular to the feed rail. An upper cutter 232 is provided at the lower part of the mounting plate 231, while a lower cutter 234 is fixed at a corresponding position on the frame 100. The mounting plate 231 drives the upper cutter 232 to move up and down, cooperating with the lower cutter 234, thereby enabling the terminals to be smoothly cut from the feed strip 260.

[0035] Furthermore, in one embodiment of the invention, reference is made to... Figure 4 The drive unit 233 includes a cutting motor 2331, a cam 2332, and a tension spring 2333. The cutting motor 2331 is mounted on the frame 100, and its output end is connected to the cam 2332. The eccentric profile of the cam 2332 abuts against the top of the mounting plate 231. When the cutting motor 2331 rotates, the change in the radius of the cam 2332 converts the rotation into a downward pressing motion of the mounting plate 231. This downward motion of the mounting plate 231 drives the upper cutter 232 to move downward, cooperating with the lower cutter 234 to complete the cutting action on the terminal. To allow the mounting plate 231 to return to its highest point, one end of the tension spring 2333 is connected to the frame 100, and the other end is connected to the mounting plate 231.

[0036] Specifically, in one embodiment of the invention, reference is made to Figure 4Two tension springs 2333 are provided, one on each side of the mounting plate 231. When the mounting plate 231 is driven downward by the cam 2332 to perform a cutting action, the tension springs 2333 are stretched. After the cutting action is completed, the cam 2332 rotates to a small radius area, and the tension springs 2333 use their stored elastic potential energy to quickly pull the mounting plate 231 and the upper cutter 232 back to their initial high position, preparing for the next feeding cycle.

[0037] Furthermore, in one embodiment of the invention, in order to make the cutting position of the terminal more precise, refer to Figure 5 or Figure 6 The mounting plate 231 is also equipped with a positioning pin 235, which is used to insert into the positioning hole 261 on the material strip 260. During the downward movement of the mounting plate 231, the positioning pin 235 enters the positioning hole 261 of the material strip 260 before the cutter, so as to ensure that the displacement of the material strip 260 in the length direction is completely locked at the moment the cutter contacts the material, thereby ensuring the cutting accuracy of the terminal.

[0038] Furthermore, in one embodiment of the invention, reference is made to... Figure 5 or Figure 6 The mounting plate 231 is also provided with a retainer 236. The retainer 236 is usually made of wear-resistant polymer material or soft metal and is located beside the upper cutter 232. The bottom surface of the retainer 236 is provided with a groove that matches the shape of the terminal body 3321. When the upper cutter 232 and the lower cutter 234 abut, the retainer 236 abuts against the part of the terminal body 3321 at the same time, thereby preventing the terminal from lifting or twisting at the moment of cutting. At the same time, after the terminal is cut, it pushes the terminal down to the conveying unit 300.

[0039] Furthermore, in one embodiment of the invention, reference is made to... Figure 5 and Figure 6 The cutting structure 230 also includes a pre-compression member 237 and a first elastic member 238. The pre-compression member 237 is slidably connected to the mounting plate 231, and its structure is in the form of a fence surrounding the upper cutter 232, with the bottom end of the pre-compression member 237 extending below the upper cutter 232. The first elastic member 238 is connected between the pre-compression member 237 and the mounting plate 231 like a compression spring. At the beginning of the cutting stroke, the pre-compression member 237 first abuts against the material strip 260, and the first elastic member 238 is compressed to generate pre-pressure, thereby pressing the material strip 260 tightly onto the feed rail, further preventing the material strip 260 from floating. Simultaneously, in conjunction with the positioning pin 235, the cutting accuracy of the terminal is further improved. Furthermore, because the pre-compression member 237 surrounds the blade, it effectively avoids accidental injury that may be caused by exposed blades.

[0040] Furthermore, in one embodiment of the invention, reference is made to... Figure 2A sensor group 240 is disposed upstream of the first drive structure 210. The sensor group 240 includes a first sensor 241 for detecting the presence or absence of terminals, and a second sensor 242 for detecting the position of the positioning hole 261 of the material strip 260. The sensor group 240 is used to feed back the captured position signals to the control system in real time, so as to correct the stepping pulses of the first feed motor 211 and the second feed motor 221, and ensure that each terminal can accurately stop on the center baseline of the upper and lower cutters 234.

[0041] Preferably, in one embodiment of the invention, reference is made to... Figure 7 Downstream of the second drive structure 220, a tailings processing structure 250 is provided. The tailings processing structure 250 includes a cylinder 251 and a cutting plate 252 installed at the output end of the cylinder 251. When the continuous strip 260 enters this area after being stripped of its terminals, the cylinder 251 drives the cutting plate 252 to cooperate with the baffle 120 installed on the frame 100 to periodically cut the long strip of waste into smaller segments, which then slide down with the hopper 253 to the collection area for collection and recycling.

[0042] In one embodiment of the invention, combined with Figure 1 and Figure 8 When the terminal is cut off, the terminal falling from below the lower cutter 234 is received by the conveying unit 300 and conveyed to the plugging unit 400.

[0043] Reference Figure 8 The conveying unit 300 includes a receiving mechanism 310, a conveying mechanism 320, and a transfer mechanism 330. The receiving mechanism 310 is located below the cutting structure 230 and is used to receive the cut terminal units. The transfer mechanism 330 is used to collect terminals in batches and transfer the terminals to the terminal insertion station. The conveying mechanism 320 is disposed between the transfer mechanism 330 and the receiving mechanism 310 and is used to transport the terminals on the receiving mechanism 310 to the transfer mechanism 330, thereby realizing terminal handling.

[0044] Specifically, in one embodiment of the present invention, referring to Figure 9 The receiving mechanism 310 includes a circular receiving tray 311 and a plurality of receiving structures 312 installed in the circumferential direction of the receiving tray 311. (See reference...) Figure 10 and Figure 11 The receiving structure 312 includes a receiving block 3121, and a guide block 3122 is provided on the receiving block 3121. In order to stabilize the position of the falling terminal and the correspondence between the subsequent gripping point, the internal cavity of the guide block 3122 is adapted to the shape of the terminal, and the terminal with position deviation is physically constrained and corrected by the inclined surface or guide edge.

[0045] Specifically, in one embodiment of the present invention, referring to Figure 12 and Figure 13 The conveying mechanism 320 includes a circular conveying tray 321 and a plurality of conveying structures 322 distributed on its circumference. The conveying structure 322 includes a mounting block 3223 and a conveying block 3221. The mounting block 3223 is used to be mounted to the conveying tray 321, and the conveying block 3221 is used to convey terminals.

[0046] Preferably, in one embodiment of the present invention, reference is made to... Figure 8 The conveying unit 300 is equipped with a drive mechanism 340. The drive mechanism 340 includes a drive motor 341, a first divider 342, and a second divider 343. The drive motor 341 is drive-connected to the first divider 342, and the first divider 342 is synchronously linked to the second divider 343 via the transmission mechanism. A handling mechanism 320 is installed at the output end of the first divider 342, and a receiving mechanism 310 is installed at the output end of the second divider 343. The first divider 342 and the second divider 343 not only drive the two turntables to rotate in an indexing motion but also drive them to perform axial lifting and lowering movements, thus ensuring that the receiving and handling actions are continuous and orderly.

[0047] In the working cycle, the first divider 342 and the second divider 343 drive the conveying mechanism 320 and the receiving mechanism 310 to perform synchronized periodic actions, respectively. To prevent spatial interference between the two sets of rotating mechanisms during operation, in this invention, when the terminal is cut off and falls, the second divider 343 drives the receiving mechanism 310 to rise to the receiving position, and the terminal falls onto the receiving mechanism 310. At the same time, the first divider 342 drives the conveying mechanism 320 to descend, and the conveying block 3221 moves to directly above and adjacent to the receiving block 3121, transferring the terminal from the receiving block 3121 to the conveying block 3221. After receiving is completed, to receive the next cut terminal, the second divider 343 drives the receiving mechanism 310 to rotate and descend, while the first divider 342 drives the conveying mechanism 320 to rotate and rise, and the conveying block 3221 moves to the transfer block position, transferring the terminal to the transfer block, completing the conveying process. Then, the first divider 342 and the second divider 343 respectively drive the conveying mechanism 320 and the receiving mechanism 310 to repeat the above actions, that is, the receiving mechanism 310 rises and the conveying mechanism 320 falls, so as to complete the receiving and transfer of the terminal.

[0048] Furthermore, in one embodiment of the present invention, referring to Figure 10 and Figure 11To prevent the terminals from shifting in position after correction due to the indexing rotation of the receiving tray 311, an air passage is provided inside the receiving block 3121, and an air suction head 3126 is provided on the receiving block 3121. The air suction head 3126 is connected to the air passage and an external negative pressure air source. The air passage is connected to the first adsorption hole 3125 on the surface of the receiving block 3121. The external negative pressure source generates negative pressure at the first adsorption hole 3125, firmly locking the corrected terminals within the position defined by the guide block 3122.

[0049] Furthermore, in one embodiment of the present invention, combined with Figure 9 and Figure 10 Since there are several receiving structures 312, there are also several air pipes connected to the suction head 3126. To prevent interference between the air pipes connected to the suction head 3126 during the rotation of the receiving mechanism 310, the present invention also provides an air path distribution structure 313. The air path distribution structure 313 includes a base 3131, which is fixedly connected to the second divider 343. The remaining part of the air path distribution structure 313 is rotatably connected to the base 3131. The receiving plate is installed at the end of the air path distribution structure 313. The part above the base 3131 is connected to the output end of the second divider 343, that is, when the second divider 343 drives the part above the base 3131 to rotate, the receiving structure 312 rotates synchronously. Furthermore, an air chamber is provided on the base 3131, and the air chamber is connected to the air path distribution structure 313. Through the connection between the air path distribution structure 313 and the suction head 3126, interference between the air pipes is avoided.

[0050] Specifically, refer to Figure 9 The air distribution structure 313 also includes a base plate 3132 rotatably connected to the base 3131. A top plate 3133 is provided above the base plate 3132, and a receiving tray 311 is mounted on the top plate 3133. The top plate 3133 and the base plate 3132 are connected by a guide rod 3134, allowing the top plate 3133 and the base plate 3132 to rotate synchronously. Simultaneously, the top plate 3133 can slide relative to the base plate 3132 along the guide rod 3134, thereby driving the receiving plate to move up and down. Meanwhile, multiple air nozzles 3135 are provided on the base plate 3132 and communicate with the air chamber at the base 3131. The air pipe of the receiving block 3121 passes through the receiving plate and the top plate 3133 and connects to the air nozzles 3135 on the base plate 3132. The air pipe and the suction head 3126 rotate synchronously as a whole, thus preventing the air pipe from becoming entangled or damaged during rotation and lifting.

[0051] Furthermore, in one embodiment of the present invention, referring to Figure 10 or Figure 11The receiving block 3121 includes a connecting portion 3123 with an "I"-shaped cross-section. The middle part of the connecting portion 3123 passes through the sliding hole of the receiving tray 311 and the two are slidably connected. The upper and lower parts of the connecting portion 3123 respectively restrict its axial travel. A second elastic member 3124 is provided between the connecting portion 3123 and the receiving tray 311. The buffering effect of the second elastic member 3124 avoids excessive mechanical impact on the terminal and prevents the terminal from deforming.

[0052] In one embodiment of the present invention, the second elastic element 3124 can be a compression spring. The second elastic element 3124 is installed between the upper part of the connecting part 3123 and the receiving tray 311. When the conveying block 3221 is pressed down, the receiving block 3121 moves downward as a whole and compresses the compression spring, thereby protecting the terminal from being deformed by pressure.

[0053] In one embodiment of the present invention, the second elastic element 3124 can be a tension spring 2333. The second elastic element 3124 is installed between the lower part of the connecting part 3123 and the receiving tray 311. When the conveying block 3221 is pressed down, the receiving block 3121 moves downward as a whole and stretches the tension spring 2333, thereby protecting the terminal from being deformed by pressure.

[0054] Furthermore, in one embodiment of the present invention, referring to Figure 13 The transport block 3221 has a groove adapted to the shape of the terminal, and a second adsorption hole 3222 is provided in the groove. When the transport plate 321 rotates to the docking position and descends, the terminal enters the groove. At this time, the second adsorption hole 3222 generates negative pressure, and the receiving block 3121 at the corresponding terminal position stops adsorbing the terminal, thereby adsorbing and extracting the terminal from the receiving block 3121. Through the precise adaptation between the groove of the transport block 3221 and the terminal, the terminal can maintain a stable position during the rotation of the transport plate 321.

[0055] Of course, a similar air distribution component as that of the receiving mechanism 310 is also provided at the conveying mechanism 320, thereby ensuring that each conveying block 3221 can rotate while avoiding entanglement and interference between the air pipes connected to the conveying blocks 3221. The air distribution component at the conveying mechanism 320 is similar in principle to the air distribution structure 313 at the receiving mechanism 310, so it will not be described in detail here.

[0056] In one embodiment of the present invention, reference is made to... Figure 8 Downstream of the conveying mechanism 320, a transfer mechanism 330 is provided. The transfer mechanism 330 is used to collect the terminals transferred one by one by the conveying mechanism 320 into groups and send them in batches to the insertion station. (Refer to...) Figure 12 The transfer mechanism 330 includes a transfer plate 332 and a linear drive assembly 331 for driving the transfer plate 332 to move.

[0057] Furthermore, in one embodiment of the present invention, referring to Figure 12 The linear drive group 331 includes a first linear driver 3311 and a second linear driver 3312.

[0058] The first linear actuator 3311 is used to drive the transfer plate 332 to perform long-stroke reciprocating movement between the transport docking position and the final insertion position. It can transfer terminals in batches to the insertion station, and at the same time drive the transfer plate 332 to perform precise displacement, so that after one terminal is placed on the transfer plate 332, the next terminal transported by the transport block 3221 can be accurately placed at the next terminal mounting position on the transfer plate 332.

[0059] In one embodiment of the present invention, reference is made to... Figure 12 The second linear actuator 3312 is installed at the output end of the first linear actuator 3311 and connected to the transfer plate 332. The second linear actuator 3312 is used to drive the transfer plate 332 to move upward, so that the transfer plate 332 and the transport block 3221 are close together so that the terminal can be transported smoothly. The second linear actuator 3312 is also used to drive the transfer plate 332 to move downward, so that the transfer plate 332 and the transport block 3221 are far apart to avoid interference during rotation.

[0060] Preferably, in one embodiment of the present invention, reference is made to... Figure 15 The transfer plate 332 includes a main body 3321 and a positioning part 3322. The main body 3321 is connected to the output end of the second linear driver 3312. The positioning part 3322 is provided with a plurality of positioning grooves 3323. The plurality of positioning grooves 3323 are equally spaced. The shape of each positioning groove 3323 is adapted to the shape of the main body 3321 of the terminal. The main body 3321 is provided with a plurality of third suction holes 3324 that generate negative pressure. Each third suction hole 3324 is correspondingly provided in the positioning groove 3323 for adsorbing the terminal, so that the terminal can remain stable during the transfer process.

[0061] Specifically, in one embodiment of the present invention, after the transport block 3221 places a terminal in a positioning slot 3323, the first linear driver 3311 drives the second linear driver 3312 to move a first distance, so that the next empty positioning slot 3323 moves to the unloading position of the transport block 3221, thereby enabling the multiple positioning slots 3323 to collect terminals in an orderly batch. When the positioning slot 3323 is full of terminals, the first linear driver 3311 drives the second linear driver 3312 to move a second distance, that is, drives the transfer plate 332 to move to the insertion unit 400.

[0062] In one embodiment of the present invention, reference is made to... Figure 14 and Figure 16The insertion unit 400 is used to receive the terminals at the transfer unit and clamp the terminals to insert them into the rubber sleeve.

[0063] Specifically, in one embodiment of the present invention, the plug-in unit 400 includes a fixing frame 410 and a clamping structure 420 mounted on the fixing frame 410. The clamping structure 420 includes a terminal receiving platform 422 and a pressing block 424 disposed opposite to each other. The terminal receiving platform 422 is driven by a third linear driver 421 and is used to receive terminals. The pressing block 424 is disposed above the terminal receiving platform 422 and is driven by a fourth linear driver 423 and is used to press down terminals.

[0064] In the initial state, there is a gap between the terminal receiving platform 422 and the pressing block 424. When the first linear driver 3311 moves a second distance, several terminals on the transfer plate 332 are transferred to the space between the terminal receiving platform 422 and the pressing block 424. At this time, the terminal receiving platform 422 is close to the bottom of the terminal, while the pressing plate is located above the terminal. The third linear driver 421 and the fourth linear driver 423 work synchronously to clamp the terminal, thereby facilitating the insertion of the terminal into the rubber sleeve.

[0065] Furthermore, in one embodiment of the present invention, referring to Figure 14 The insertion unit 400 is also provided with a fifth linear driver 430. The fixing bracket 410 is installed at the output end of the fifth linear driver 430. After the terminal is clamped and stabilized, the fifth linear driver 430 can drive the terminal to move toward the rubber sleeve, thereby realizing the insertion of the terminal into the rubber sleeve.

[0066] Furthermore, in one embodiment of the present invention, referring to Figure 16 To prevent damage to the terminals during clamping, when the terminals are transferred to the terminal receiving platform 422 by the transfer plate 332, the height of the terminal receiving platform 422 is as close as possible to the lower surface of the terminals. Simultaneously, a buffer block 425 is provided at the lower pressure block 424. The buffer block 425 is connected to the lower pressure block 424 via a third elastic element 426, meaning the buffer block 425 replaces the lower pressure block 424 in clamping the terminals. Because the buffer block 425 has the third elastic element 426, deformation of the terminals at the clamping point is prevented when they are clamped by the terminal receiving platform 422 and the buffer block 425.

[0067] Furthermore, to ensure the clamping effect, refer to Figure 16 The number of buffer blocks 425 corresponds to the number of terminals, so that each terminal is clamped individually, resulting in better terminal clamping effect and avoiding the situation where some terminals are not clamped properly when the lower block 424 is pressed down as a whole.

[0068] In one embodiment of the present invention, a guide block 3122 is provided at the receiving block 3121, and a first adsorption hole 3125 is provided on the receiving block 3121, so that the terminal is locked on the receiving block 3121 after being received by the receiving plate. At the same time, a corresponding groove and a second adsorption hole 3222 adapted to the terminal are provided on the transport block 3221, so that the terminal is locked on the transport block 3221 during the transport process. When the terminal is transferred from the transport block 3221 to the transfer block, the transfer block is also provided with a groove and a third adsorption hole 3324 adapted to the terminal, so that the position of the terminal is fixed after being transported to the transfer block. That is, after the terminal falls from the cutting unit 200, during the entire process of being transported on the conveying unit 300, the terminal is repositioned and stabilized by negative pressure adsorption each time the terminal is transferred, so that the terminal is accurately positioned when it is transferred to the insertion unit 400. At the same time, each terminal is individually clamped by the buffer block 425, which makes the terminal more stable in posture when it is clamped, thus making the terminal more accurate when inserted into the rubber sleeve.

[0069] The present invention also discloses a terminal production line, which includes the above-mentioned new energy connector terminal implantation device and possesses all the advantages of the terminal implantation device.

[0070] It is understood that those skilled in the art can make equivalent substitutions or changes to the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
