[0040] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In order to solve the problem of circuit and signal transmission interruption caused by insufficient stability of terminals in the connector in the prior art, a multi-line motor and differential lock control connector is provided, such as Figure 1-5 As shown, it includes a needle seat 1, a plug 2 and a fixing clip 3. The plug 2 is provided with an inner lock, and the needle seat 1 is provided with a lock buckle corresponding to the inner lock. The inner lock and the lock buckle are buckled together, so that the plug 2 is inserted into the needle seat 1. Figure 1 As shown, the plug 2 is provided with a first hole seat 7, a second hole seat 8 and a third hole seat 9. The first hole seat 7 is provided with a power terminal 10, the second hole seat 8 is provided with a motor terminal 11, and the third hole seat 9 is provided with a signal terminal 12. Figure 2 and 3 As shown, the needle seat 1 is provided with a power pin 4, a motor pin 5 and a signal pin 6. When the plug 2 is connected to the needle seat 1, the power pin 4 is plugged into the power terminal 10 in the first hole seat 7, the motor pin 5 is plugged into the motor terminal 11 in the second hole seat 8, and the signal pin 6 is plugged into the signal terminal 12 in the third hole seat 9.

[0042] like Figure 2 As shown, there are multiple power pins 4, motor pins 5 and signal pins 6 on the pin holder 1. The power pins 4, motor pins 5 and signal pins 6 are fixed on the pin fixing plate 19, and a fence 20 is provided on the pin fixing plate 19. The fence 20 separates the power pins 4, motor pins 5 and signal pins 6. A shielding layer is installed outside the fence 20 to ensure a safe creepage distance between the strong current terminal and the weak current terminal without mutual interference.

[0043] like Figure 4 As shown, the fixing clip 3 is movably installed in the middle section of the plug 2, and when the lower ends of the power terminal 10, the motor terminal 11 and the signal terminal 12 pass through the hole seat, the power terminal 10, the motor terminal 11 and the signal terminal 12 are clamped in the plug 2 again through the fixing clip 3. The power terminal 10, the motor terminal 11 and the signal terminal 12 are provided with a limiting member 17 and a limiting groove 18, and the power terminal 10, the motor terminal 11 and the signal terminal 12 are pressed in the plug 2 through the limiting member 17. The limiting groove 18 cooperates with the fixing clip 3, and when the plug 2 is inserted into the needle seat 1, the power terminal 10, the motor terminal 11 and the signal terminal 12 cooperate with the fixing clip 3 through the limiting groove 18 and are fixed in the plug 2.

[0044] like Figure 5As shown, the fixing clip 3 is provided with a pre-installed lock buckle 13, the needle seat 1 is provided with a pre-installed lock port 14, the pre-installed lock buckle 13 is engaged in the pre-installed lock port 14, and the fixing clip 3 is slidably arranged on the plug 2 through the pre-installed lock buckle 13. The shape of the fixing clip 3 matches the shape of each hole seat in the plug 2. The fixing clip 3 is pre-installed on the plug 2 through the pre-installed lock buckle 13, and then the power terminal 10, the motor terminal 11 and the signal terminal 12 are respectively passed through the fixing clip 3 and installed in the plug 2.

[0045] When the fixing clip 3 and the terminal are installed, the needle holder 1 is plugged into the plug 2, and the upper and lower end surfaces of the needle holder 1 squeeze the upper and lower end surfaces of the plug 2, so that the fixing clip 3 on the plug 2 is squeezed into the plug 2, and then the fixing clip 3 fits in the limiting groove 18 of the terminal, and the terminal and the fixing clip 3 are fixed in the plug 2.

[0046] The terminal provided in the present application is restricted in the plug 2 by its own restriction member 17, so that the relative position of the terminal is fixed. When the needle seat 1 is plugged into the plug 2, the fixing clip 3 in the plug 2 is squeezed to move the fixing clip 3 downward, so that the fixing clip 3 falls into the limiting groove 18 on the terminal, so that the position of the terminal in the plug 2 is completely fixed, preventing the terminal from loosening and detaching, and improving the stability of the connector. At the same time, the fixing clip 3 can be used to check whether the terminal is plugged in place, improve production efficiency, and modify the position of the terminal in time.

[0047] Example 1

[0048] In order to prevent the fixing clip 3 from being separated from the limiting groove 18 of the terminal, as shown in FIG. Figure 6-8 As shown, a secondary lock buckle 15 is provided on the fixing clip 3, and a secondary lock opening 16 is provided in the needle seat 1, and the secondary lock buckle 15 is clamped in the secondary lock opening 16. When the needle seat 1 is not plugged into the plug 2, as shown in FIG. Figure 7 As shown, the secondary lock buckle 15 abuts against the outer edge of the secondary lock opening 16 , and a channel is formed between the fixing clip 3 and the plug 2 , and the channel can accommodate the terminal to pass through, so that the terminal can be smoothly inserted into the plug 2 .

[0049] like Figure 8 As shown, when the needle seat 1 is plugged into the plug 2, the secondary lock 16 is plugged into the secondary lock 16, and the fixing clip 3 is fixed on the plug 2 through the secondary lock buckle 15. The fixing clip 3 moves downward and falls into the limiting groove 18 on the terminal, so that the position of the terminal in the plug 2 is completely fixed, preventing the terminal from loosening and disengaging, and improving the stability of the connector.

[0050] The fixing clip 3 is provided with a widened unlocking piece 21, which is hollowed out on the upper end surface of the fixing clip 3. When it is necessary to check the use status of the terminal and disassemble the movable terminal, the needle seat 1 is separated from the plug 2. At this time, the widened unlocking piece 21 is pulled to move the fixing clip 3 upward. The fixing clip 3 leaves the limiting groove 18 of the terminal, and the connection relationship between the terminal and the fixing clip 3 is released and restored to the initial state, which is convenient for moving and disassembling the terminal.

[0051] Example 2

[0052] like Figure 9-13 As shown, the secondary lock buckle 15 includes a first component 1501 and a second component 1502, and the first component 1501 and the second component 1502 are integrally formed. The connection between the first component 1501 and the second component 1502 is hingedly arranged on the fixing clip 3 through a hinge axis. The front end surface of the first component 1501 and the contact surface of the plug 2 are inclined surfaces that abut against each other, so that the first component 1501 can slide smoothly into the secondary lock port 16.

[0053] like Fig.10 As shown, the secondary lock 15 includes at least a first use state, and in the first use state, the first component 1501 and the second component 1502 are in a horizontal state, and the front end of the first component 1501 is against the outer edge of the secondary lock 16. When the needle seat 1 is not plugged into the plug 2, the first component 1501 of the secondary lock 15 is against the outer edge of the secondary lock 16, and the second component 1502 of the secondary lock 15 is against the fixing clip 3, and a channel is formed between the fixing clip 3 and the plug 2, and the channel can accommodate the terminal to pass through, so that the terminal can be smoothly inserted into the plug 2.

[0054] like Fig.11 As shown, the secondary lock 15 also includes a second use state, and in the second use state, the first component 1501 is in a downward tilted state, the second component 1502 is in an upward tilted state, and the front end of the first component 1501 is against the inner edge of the secondary lock 16. Before the terminal is inserted into the needle seat 1, the fixing clip 3 is manually pressed, and the fixing clip 3 moves downward, so that the first component 1501 of the secondary lock 15 is tilted downward into the secondary lock 16, and the front end of the first component 1501 is against the inner edge of the secondary lock 16. The second component 1502 is tilted upward, away from the fixing clip 3, so that the second component 1502 forms a graspable component.

[0055] When the needle seat 1 is plugged into the plug 2, in order to match the upwardly tilted shape of the second component 1502, as shown in FIG. Fig.13 As shown, the upper end surface of the needle seat 1 is correspondingly changed into a plane with a slope. The slope is a plane that gradually increases from the outside to the inside. When the needle seat 1 is gradually inserted into the plug 2, its slope pushes the second component 1502 to return to a horizontal state.

[0056] like Fig.12 As shown, the secondary lock 15 also includes a third use state, and in the third use state, the first component 1501 and the second component 1502 are in a horizontal state, and the first component 1501 is inserted into the secondary lock 16. When the needle seat 1 and the plug 2 are plugged in, the first component 1501 and the second component 1502 are in a horizontal state against the fixing clip 3, the first component 1501 is inserted into the secondary lock 16, and the fixing clip 3 is fixed on the plug 2 through the secondary lock 15. The fixing clip 3 moves downward and falls into the limiting groove 18 on the terminal, so that the position of the terminal in the plug 2 is completely fixed, preventing the terminal from loosening and disengaging, and improving the stability of the connector.

[0057] When it is necessary to check the use status of the terminal and disassemble the movable terminal, separate the needle seat 1 from the plug 2. At this time, the second part 1502 of the secondary lock 15 is tilted upward and away from the fixing clip 3, so that the second part 1502 forms a graspable part. Lift the second part 1502 upward to move the fixing clip 3 upward. The fixing clip 3 leaves the limiting groove 18 of the terminal, and the connection relationship between the terminal and the fixing clip 3 is released and restored to the initial state, which is convenient for moving and disassembling the terminal.

[0058] The use process of the embodiment of the present invention is as follows:

[0059] When installing the power terminal 10, the motor terminal 11 and the signal terminal 12, the fixing clip 3 is pre-installed on the plug 2. At this time, the first hole seat 7 and the fixing clip 3 form a complete channel to accommodate the power terminal 10, the second hole seat 8 and the fixing clip 3 form a complete channel to accommodate the motor terminal 11, and the third hole seat 9 and the fixing clip 3 form a complete channel to accommodate the signal terminal 12. After the power terminal 10, the motor terminal 11 and the signal terminal 12 enter the plug 2, the needle seat 1 cooperates with the plug 2 to push the fixing clip 3 to deflect inward. At this time, the channel becomes narrower, limiting the position of the power terminal 10, the motor terminal 11 and the signal terminal 12.

[0060] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
