[0027] From the above, the new energy vehicle wire harness connector provided by the embodiment of the application is tightly plugged, when the connecting terminal 2 needs to be connected with the socket, the wire harness 3 is first crimped with the connecting terminal 2, then the abutment plate 54 is pulled downward, the abutment plate 54 drives the sliding block 53 and the locking shell 52 to slide downward until the bottom of the sliding block 53 contacts the plastic shell 4, at this time, the locking shell 52 completely enters the inside of the third sliding groove 43; then the end of the wire harness 3 away from the connecting terminal 2 is inserted through the plug-in slot 41 and the side of the plastic shell 4, then the connecting terminal 2 is aligned with the plug-in slot 41 and inserted into the inside of the plug-in slot 41, the first clamping block 51 slides in the inside of the second sliding groove 42 until the side of the connecting terminal 2 connected with the wire harness 3 contacts the plastic shell 4; then the abutment plate 54 is pressed to move the abutment plate 54 upward, the abutment plate 54 drives the sliding block 53 and the locking shell 52 to move upward, the top of the locking shell 52 is provided with a slot hole matched with the first clamping block 51, the first clamping block 51 gradually slides into the inside of the slot hole at the top of the locking shell 52, when the first clamping block 51 completely enters the inside of the slot hole, the pressing of the abutment plate 54 is stopped, at this time, the connecting terminal 2 is locked in the inside of the plug-in slot 41 through the locking mechanism, the stability of the connection between the connecting terminal 2 and the plastic shell 4 can be enhanced, when the connecting terminal 2 needs to be replaced, the abutment plate 54 is pulled downward to separate the locking shell 52 from the first clamping block 51, then the terminal is pulled out from the plug-in slot 41; then the plastic shell 4 and the connecting terminal 2 are inserted into the inside of the connecting shell 12, the outer surface of the plastic shell 4 contacts and presses the buffer pad 122, at the same time, the second clamping block 431 contacts the edge of the connecting shell 12, the top of the second clamping block 431 is provided with a curved surface, when the clamping strip 44 drives the second clamping block 431 to move, the connecting shell 12 applies a vertical downward component force to the second clamping block 431 through the curved surface, so that the second clamping block 431 moves downward and enters the inside of the fourth sliding groove 124, at the same time, the clamping strip 44 bends and enters the inside of the fourth sliding groove 124 until the plastic shell 4 and the connecting terminal 2 contact the base plate 11, at this time, the plug 111 is inserted into the inside of the plug hole 21, the connection between the connecting terminal 2 and the socket is completed, because the clamping strip 44 bends and continuously applies an upward elastic force to the second clamping block 431, when the plastic shell 4 contacts the base plate 11, the second clamping block 431 is aligned with the clamping port 125 and moves upward and is clamped into the inside of the clamping port 125 under the elastic force of the clamping strip 44, when the plastic shell 4 is subjected to external pulling force caused by non-human factors, the clamping port 125 prevents the second clamping block 431 from moving, so that the plastic shell 4 is prevented from sliding outward from the connecting shell 12, the connection between the plastic shell 4 and the connecting shell 12 is reinforced, when the plastic shell 4 needs to be pulled out from the connecting shell 12, a tool is used to press the second clamping block 431, the second clamping block 431 moves downward and bends one end of the clamping strip 44, the second clamping block 431 is separated from the clamping port 125, then the wire harness 3 is pulled, the wire harness 3 pulls the connecting terminal 2 and the plastic shell 4 to move in a direction away from the base plate 11, the second clamping block 431 enters the inside of the fourth sliding groove 124, then the plastic shell 4 is pulled out by continuously pulling the wire harness 3.After the plastic shell 4 is inserted into the connection shell 12, a pair of buffer pads 122 symmetrically arranged inside the connection shell 12 wrap the outer surface of the plastic shell 4. The buffer pads 122 can exert a certain pressure on the outer surface of the connection shell 12 to fix it. When the connector is subjected to vibration, the buffer pads 122 can absorb part of the kinetic energy of the plastic shell 4, reduce the amplitude of the shaking of the plastic shell 4, and maintain the fixing effect on the plastic shell 4. Since the buffer pads 122 have good elasticity and deformation ability, they can avoid gaps between the plastic shell 4 and the buffer pads 122, thereby maintaining the fixing effect on the plastic shell 4. When the plastic shell 4 is inserted into the connection shell 12, the abutment plate 54 abuts against the inner surface of the connection shell 12 and slides in the first sliding groove 123. After the plastic shell 4 contacts the base plate 11, the abutment plate 54 abutting against the connection shell 12 can prevent the locking shell 52 and the sliding block 53 from sliding downward due to gravity or vibration, causing the locking shell 52 and the first clamping block 51 to loosen.
[0028] In some embodiments, referring to Figure 1 and Figure 5 , the connection shell 12 is sleeved with a dustproof shell 6, the wire harness 3 passes through the dustproof shell 6, the base plate 11 is provided with a mounting groove 112 and a plurality of connecting grooves 113, the mounting groove 112 is provided with a sealing pad 7, the dustproof shell 6 is fixedly provided with a plurality of connecting rings 61, one end of the dustproof shell 6 away from the wire harness 3 is clamped in the mounting groove 112 and abuts against the base plate 11, the connecting rings 61 are clamped in the connecting grooves 113 and are bolted to the base plate 11, and one end of the dustproof shell 6 abuts against the sealing pad 7.
[0029] In this way, after the plastic shell 4 and the connection shell 12 are connected, the wire harness 3 passes through the opening formed in the dustproof shell 6, one end of the dustproof shell 6 close to the base plate 11 is aligned with the mounting groove 112 and clamped in the mounting groove 112, at this time, each connecting ring 61 is clamped in the connecting groove 113, then the connecting ring 61 and the base plate 11 are bolted, and one end of the dustproof shell 6 close to the base plate 11 is pressed against the sealing pad 7 to form a seal. The dustproof shell 6 can block external dust and liquid from entering the connection shell 12 through the slot holes formed in the connection shell 12, thereby protecting the facilities inside the connection shell 12.
[0030] Optionally, in some embodiments, referring to Figure 1 , the dustproof shell 6 away from the base plate 11 is fixedly provided with a sealing sleeve 8, and the wire harness 3 passes through the sealing sleeve 8 and abuts against the inner circumferential surface of the sealing sleeve 8.
[0031] In this way, the inner circumferential surface of the sealing sleeve 8 can contact the surface of the wire harness 3 and form a seal, thereby preventing external dust and liquid from entering the dustproof shell 6 through the gap between the dustproof shell 6 and the wire harness 3, and enhancing the protection effect of the dustproof shell 6 on the connector.
