DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] like Figure 1 and Figure 2 As shown, a new type of terminal connector comprises: a mounting box 1, the interior of the mounting box 1 is a cavity and the rear end is open, a spring rod 10 extending from front to back through the axis in the inner cavity of the mounting box 1 is fixedly provided with two connecting plates distributed left and right, the rear end surfaces of the two connecting plates are jointly fixedly provided with a U-shaped plate 2 with a U-shaped opening facing upward, a plug-in mechanism 3 is jointly provided between the mounting box 1, the U-shaped plate 2 and the connecting seat, a plurality of groove groups arranged equidistantly from left to right are provided on the mounting box 1, the groove group includes two L-shaped grooves 11 distributed left and right and connected to the inner cavity of the mounting box 1, and the L-shaped grooves 11 correspond to the wiring harness on the corresponding terminal.

[0033] like Figure 1 and Figure 2 As shown, the plug-in mechanism 3 includes a mounting block 30, and the left and right end surfaces of the connecting seat are fixedly provided with mounting blocks 30, and the front end surface of the mounting block 30 is fixedly provided with two multi-stage telescopic rods 300 distributed up and down and with axes extending from back to front, and the inner wall of the mounting box 1 is fixedly provided with guide blocks 301 corresponding to the multi-stage telescopic rods 300 one by one, and the guide blocks 301 are provided with guide holes matching the multi-stage telescopic rods 300.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, the upper end surface of the U-shaped plate 2 is provided with a wire pressing unit 31 for pressing the wire harness, and the wire pressing unit 31 includes a sliding plate 310. The upper end surface of the U-shaped plate 2 is provided with a sliding plate 310 corresponding to the terminals one by one for sliding back and forth. The sliding plate 310 is provided with two groups of plate groups distributed left and right, and the plate group includes two arc-shaped wire pressing plates 311 distributed left and right. The front end of the wire pressing plate 311 is chamfered, and the plug-in mechanism 3 also includes a driving group 32 for driving the wire pressing plate 311 to press the wire harness; the installation box 1 is provided with a locking unit 34 for locking it with the connecting seat.

[0035] During operation, the multi-stage telescopic rod 300 is first stretched so that the multi-stage telescopic rod 300 is in a stretched state, and then the guide hole on the guide block 301 is aligned with the multi-stage telescopic rod 300, and the installation box 1 is manually moved so that the multi-stage telescopic rod 300 passes through the guide hole. Secondly, it should be noted that the diameter of the last section of the multi-stage telescopic rod 300 is the same as the diameter of the guide hole. Therefore, in the process of the installation box 1 moving backward to connect to the terminal, the multi-stage telescopic rod 300 and the guide hole are first matched to preliminarily guide the backward movement of the installation box 1, and then the last section of the multi-stage telescopic rod 300 is connected to the guide hole for guidance, which is convenient for the subsequent locking process.

[0036] Afterwards, the terminals and wiring harness are manually placed above the U-shaped plate 2, and the terminals are initially inserted into the plug-in slots on the connecting seat, the wiring harness is moved into the installation box 1 through the corresponding L-shaped slots 11, and the wiring harness is located between the two wire pressing plates 311 in the corresponding plate group. Then, the installation box 1 is manually pushed to move the installation box 1 backward. During the backward movement of the installation box 1, the driving group 32 is used to make the terminals first inserted into the plug-in slots and clamped, and then the two corresponding wire pressing plates 311 cooperate with each other to compress the wiring harness, and the locking unit 34 is used to lock the wire pressing state of the wire pressing plates 311. Finally, the right end portion of the installation box 1 covers the connecting seat, and the locking unit 34 is used to lock the installation box 1 and the connecting seat again to complete the terminal plugging process.

[0037] like Figure 2 As shown, two rubber strips 12 perpendicular to each other and used for sealing the L-shaped groove 11 are fixedly disposed on both left and right end surfaces of the inner wall of the L-shaped groove 11 .

[0038] During operation, when the wiring harness is placed in the installation box 1, the elastic material of the rubber strip 12 enables the wiring harness to pass through the L-shaped groove 11 and enter the installation box 1. Secondly, after the wiring harness enters the installation box 1, the two rubber strips 12 in the same L-shaped groove 11 cooperate with each other to seal the L-shaped groove 11, thereby ensuring the protection effect of the installation box 1 on the internal wiring harness and terminals, and at the same time improving the convenience of the terminal plugging process.

[0039] like Figure 2 , Figure 3 and Figure 4As shown, the wire pressing unit 31 also includes a T-shaped frame 312, the upper end surface of the sliding plate 310 is fixedly provided with a T-shaped frame 312, and the upper end surface of the sliding plate 310 is fixedly provided with two left-right symmetrical L-shaped frames 313, the T-shaped frame 312 is located between the two L-shaped frames 313, and the plate group is arranged between the corresponding L-shaped frame 313 and the horizontal section of the T-shaped frame 312, one of the wire pressing plates 311 in the same plate group is fixedly provided on the horizontal section of the T-shaped frame 312, and the other wire pressing plate 311 is slidably provided on the vertical section of the L-shaped frame 313 through a sliding column extending from left to right through an axis, and a spring 1 314 is fixedly provided between the sliding plate 310 and the U-shaped plate 2 through a square block.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, the driving group 32 includes a second spring 320, and a second spring 320 mounted on the corresponding sliding column is fixedly arranged between the vertical section of the L-shaped frame 313 and the corresponding wire pressing plate 311. The end surface of the sliding column away from the wire pressing plate 311 is fixedly provided with a right-angled trapezoidal matching block 321, and the two matching blocks 321 corresponding to the same sliding plate 310 are symmetrical on the left and right. The matching block 321 on the right side of the same sliding plate 310 is taken as an example for explanation, and the inclined surface of the matching block 321 is inclined to the right from front to back, and a plurality of driving blocks 322 that match the matching blocks 321 one by one are fixedly arranged on the U-shaped plate 2 through vertical columns.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the sliding plate 310 and the connecting seat are jointly provided with a clamping unit 33 for clamping the terminal, and the clamping unit 33 includes a pushing circular plate 330. The pushing circular plate 330 located at the rear side of the T-shaped frame 312 is fixedly provided on the sliding plate 310 through an L-shaped bar.

[0042] During operation, after the terminals and the wiring harness are placed at the specified positions, the installation box 1 is manually moved backwards, and the installation box 1 drives the U-shaped plate 2 to move backwards synchronously through the spring rod 2 332, and the U-shaped plate 2 drives the sliding plate 310 and the pushing circular plate 330 to move backwards synchronously, and the pushing circular plate 330 moves backwards to contact the terminal and then pushes the terminal backward to be inserted into the plug-in slot of the connecting seat. When the terminal is inserted into the corresponding plug-in slot, as the installation box 1 continues to move, the spring 1 314 is continuously compressed, so the pushing circular plate 330 is pressed against the terminal in the front-to-back direction. At this time, the sliding plate 310, the wire pressing plate 311 and the pushing circular plate 330 stop moving relatively in the front-to-back direction. Then, the installation box 1 is continuously pushed backward, and the U-shaped plate 2 is continuously moved backward, and the U-shaped plate 2 drives all the driving blocks 322 to move backward. It should be noted that the driving blocks 322 on the left and right sides cooperate with the adjacent single matching blocks 321, and the remaining driving blocks 322 cooperate with the two adjacent matching blocks 321. The driving blocks 322 move backward and contact the corresponding matching blocks 321. Through the contact between the driving blocks 322 and the inclined surfaces of the matching blocks 321, the matching blocks 321 drive the sliding posts to move, and the two sliding posts on the same sliding plate 310 approach each other. The sliding posts drive the wire pressing plates 311 thereon to move synchronously, and the spring 2 320 is stretched, so the slidingly installed wire pressing plates 311 move and close with the fixedly installed wire pressing plates 311, and the two cooperate with each other to press the corresponding wire harness, and the U-shaped plate 2 stops moving. The wire harness is pressed by the wire pressing plates 311 to avoid the problem of looseness or poor contact of the terminals or wire harnesses due to vibration or shaking during subsequent use.

[0043] like Figure 2 and Figure 5 As shown, the clamping unit 33 also includes a rectangular plate 331, and the front end surface of the connecting seat is fixedly provided with multiple groups of plate groups corresponding to the terminals one by one, and the plate group includes two rectangular plates 331 distributed on the left and right, and the opposite surfaces of the two rectangular plates 331 are fixedly provided with spring rods 332 with axes extending from left to right, and the telescopic ends of the spring rods 332 are fixedly provided with clamping plates 333 for clamping the terminals.

[0044] like Figure 5 As shown, the two locking plates 333 corresponding to the same plate group are symmetrical about the corresponding pushing circular plate 330. Taking the locking plate 333 on the left side as an example, the locking plate 333 is divided into a slope section, a raised section and a rectangular section from front to back, and the raised section of the locking plate 333 faces the right side, and the right end face of the slope section is inclined to the right from front to back.

[0045] like Figure 5As shown, two upper and lower symmetrical U-shaped blocks 334 are fixedly provided on the opposite back sides of the two corresponding positioning plates 333, and the U-shaped opening of the U-shaped block 334 faces the corresponding terminal. The inner side surface of the horizontal section of the U-shaped block 334 away from the corresponding positioning plate 333 is tightly attached to the side end surface of the terminal, and the horizontal section is chamfered.

[0046] When working, in the process of pushing the circular plate 330 to push the terminal into the plug-in slot on the connecting seat, the terminal moves backward and first contacts the inclined sections of the corresponding two positioning plates 333. The inclined sections of the positioning plates 333 guide the subsequent movement of the terminal by initially limiting the terminal. As the terminal continues to move backward, the terminal contacts the raised sections of the positioning plates 333 and squeezes the positioning plates 333, so that the corresponding two positioning plates 333 move away from each other, the spring rod 332 is compressed, and finally the terminal moves into the plug-in slot. At this time, the terminal and The rectangular section of the clamping plate 333 is in close contact, and the front end of the terminal is located behind the raised section of the clamping plate 333. The elastic force generated by the deformation of the second spring rod 332 makes the corresponding clamping plate 333 close to the terminal and press the terminal. The two clamping plates 333 cooperate to clamp the terminal in the left and right directions. Secondly, the raised section of the clamping plate 333 restricts the terminal in the plug-in slot, and cooperates with the circular plate 330 to press the terminal, so as to avoid the problem of the terminal being vibrated and falling off or shifting during the subsequent use process. The convenience of terminal plugging and subsequent removal is improved through elastic clamping.

[0047] In the process of the two locking plates 333 approaching the terminal and finally pressing the terminal, all the corresponding U-shaped blocks 334 move synchronously, and finally the four U-shaped blocks 334 corresponding to the same terminal cooperate to implement the upper and lower clamping limit of the terminal, further ensuring the tight connection between the terminal and the connecting seat, improving the plug-in stability of the terminal during subsequent use, and avoiding the problem of shaking or position deviation between the terminal and the connecting seat affecting the normal use of the terminal connector.

[0048] like Figure 2 and Figure 3 As shown, the locking unit 34 includes a rotating rod 340, and the opposite back surfaces of the two vertical sections of the U-shaped plate 2 are rotatably provided with a rotating rod 340 with a vertical axis through two connecting strips distributed up and down, and a locking strip 341 is fixedly sleeved on the rotating rod 340, and locking holes 342 are opened on the left and right end surfaces of the connecting seat, and the inner wall of the locking hole 342 is chamfered, and a locking column 343 corresponding to the locking hole 342 is fixedly provided at one end of the locking strip 341, and a spring three 344 is fixedly provided between the other end of the locking strip 341 and the vertical section of the U-shaped plate 2.

[0049] like Figure 2 and Figure 3As shown, the locking unit 34 also includes a locking hole 345. The left and right sides of the installation box 1 are both provided with locking holes 345. The installation block 30 is provided with a threaded hole 346 that matches the locking hole 345. The threaded hole 346 is internally threaded with a bolt.

[0050] During operation, before plugging in the terminals, first manually press the two locking strips 341 so that the front end parts of the two locking strips 341 compress the spring three 344, and the rear end parts of the locking strips 341 drive the corresponding locking columns 343 to move synchronously to avoid hindering the subsequent backward movement of the installation box 1 and the U-shaped plate 2. Then, the installation box 1 is manually pushed backward to plug in the terminals. When the terminals are inserted into the plug-in slots and the wiring harness is clamped, the two locking strips 341 are manually loosened, and the elastic force generated by the deformation of the spring three 344 makes the locking strips 341 drive the locking columns 343 to fit into the corresponding locking holes 342, thereby realizing the mutual locking of the U-shaped plate 2 and the connecting seat. When the terminals need to be removed later, the locking strips 341 are manually pressed first to make the locking columns 343 withdraw from the locking holes 342, and then the U-shaped plate 2 and the connecting seat are separated.

[0051] Afterwards, as the installation box 1 continues to move, the locking hole 345 on the installation box 1 is aligned with the threaded hole 346 at the corresponding position, and then the installation box 1 and the connecting seat are manually fixed by screwing the bolt into the threaded hole 346, thereby completing the assembly of the terminal connector.

[0052] By successively completing the locking between the U-shaped plate 2 and the connecting seat, and the locking between the installation box 1 and the connecting seat, the U-shaped plate 2 and the front end part of the connecting seat are finally locked into the installation box 1, and the installation box 1 protects the terminals, wiring harness and terminal connections inside it. After the installation box 1 is locked, there are elastic contacts between the installation box 1 and the U-shaped plate 2, the U-shaped plate 2 and the sliding plate 310, and the sliding plate 310 and the connecting seat. The multiple spring rods 10, spring 1 314, spring 2 320 and spring 344 are arranged to absorb the shaking or vibration of the terminals and connectors during subsequent use, thereby preventing the terminals from loosening or falling off from the connecting seat.
